The scope of use of punches, punches are generally divided into several types

All the places where thin metal plates and strips are used, except for welding or sheet metal forming, are basically punching work. Large industries include automobiles (most of the body), motors (silicon steel sheets), military (cartridge shells), batteries (shells) and so on; Small things include gaskets, cups and plates, etc. Some wire rods and plates will also be used in the forming process.

Stamping equipment mainly includes crank presses, friction presses, double-action drawing presses, fine blanking presses, high-speed presses, CNC stamping die rotary head presses and other types.

The main partners of punching machines are all kinds of (continuous) punching dies, punching dies, drawing dies, bending dies, dressing dies and other so-called cold stamping dies.

A punch press is a press that is stamped.

Presses include hydraulically driven and mechanically driven.

Mechanical transmission is called a punch press.

Hydraulically driven presses are also known as hydraulic presses and hydraulic presses.

In national production, the stamping process has the advantages of saving materials and energy compared with traditional machining, high efficiency, low technical requirements for the operator and products that can not be achieved by machining through various mold applications, so it is more and more widely used.

Stamping production is mainly for sheet metals. It can pass through the mold, and can make blanking, punching, forming, drawing, dressing, fine blanking, shaping, riveting and extrusion, etc., which are widely used in various fields. Such as the switches and sockets we use, cups, cupboards, plates, computer cases, and even missiles and airplanes ......There are a lot of parts that can be produced by punching through molds.

Haha, I am a professional punch maintenance, in 11 years of maintenance experience, summed up, the general auto parts industry, the tonnage of the punch will not be too small, the home appliance industry, will not be too small, as for the small hardware industry, 100 tons is considered large, you are free to our ** on the Kunshan Huanzhen electromechanical.

Most of them are used for stamping and forming, which is related to all aspects, small and large hardware processing, terminal molding, electronic appliances and other mass forming metals, large to auto parts shells.

Motors, motors, compressors, hardware tableware, I am a compressor, open an AIDA CNC punch, and consume 24t silicon steel sheets together with 15 punches in 8 hours.

24*15*3 (three shifts).

According to its use and characteristics, the punch has the following types, which can be applied to one or more stamping processes.

1.Universal punch press.

The universal punch press is the most common type of press. It is suitable for a variety of stamping processes, such as blanking, shallow drawing, bending and stamping. General purpose punch press according to nominal pressure.

The size is divided into large, medium, and small. The nominal pressure of the small punch is less than 1000kn; 1000 3000kN for medium punches; More than 3000kn is a large punch. According to the characteristics of the bed structure, the general punch is divided into two types: open punch and closed punch.

The pressure of the open punch press is smaller, generally between 25-4000kN. The nominal pressure of the closed punch is larger, generally above 1600 16000kn.

2.Drawing (drawing) punch.

This kind of punch is suitable for the drawing process, according to the position of its transmission system is divided into upper transmission and lower transmission punch: according to the number of its sliders, it is divided into single-acting, double-acting, three-action drawing punch.

3.Dedicated punch press.

The special punch is used to stamping a certain complex shape of the part, such as the die rotary head press belongs to this kind of special punch.

4.Fine punching press.

Fine blanking punch is a punch specially suitable for punching precision parts.

5.Fine press.

Fine press is a punch machine suitable for precision extrusion, leveling, embossing and other stamping operations.

6.High-speed punching press.

The high-speed punch has a higher number of strokes per minute (referred to as strokes per minute) of the slider, or its corresponding automatic feeding speed is higher, which is suitable for the production of automatic forming and stamping operations of large quantities of products.

1.According to the driving force of the slider, it can be divided into two types: mechanical type and hydraulic type, so the punch press is divided into two types according to the different driving force it uses

1) Mechanical

powerpress)

2) Hydraulic punch (hydraulic

press)

In general, sheet metal stamping is processed, and most of them use mechanical punching machines. Hydraulic punch according to the different liquids used, there are hydraulic punches and hydraulic punches, the current use of hydraulic punches accounted for the majority, hydraulic punches are mostly used in large machinery or special machinery.

2.Classification according to the way the slider moves:

According to the slider movement mode classification has single-acting, double-acting, three-action punches, but the most used at present is a single-action punch of a slider, and the double-action and three-action punches are mainly used in the extension processing of automobile bodies and large processing parts, and their number is very small.

If there is a problem with the cylinder head and the cylinder gasket in the middle, it is called a stamping machine. That is, the cylinder gasket of the ramjet has a gasket on the contact surface between the engine and the cylinder head, which isolates the engine oil passage from the waterway and prevents water and oil from leaking into the cylinder, resulting in many faults in the stamping machine: high water temperature, cylinder bolting, air in the waterway, etc.

The cylinder block and crankcase are usually cast into a single unit, collectively known as the cylinder block, which is the shell and assembly basis of the engine, and is generally made of high-quality alloy cast iron or aluminum alloy. The empty cylinder block in the cylinder block is called the cylinder block, and the surface of the cylinder block is called the cylinder wall. The cylinder is the place where the gas is exchanged and burned, and it is also the trajectory of the piston movement.

In order to ensure the sealing between the piston and the cylinder and reduce wear and tear, the cylinder wall should have high machining accuracy and low surface roughness. In order to dissipate the heat of the cylinder during operation, there is a sandwich hollow between the cylinder block and the cylinder liner, called the water jacket. The oil pan is used to store lubricating oil, so it is commonly known as the oil pan.

Generally, it is stamped by thin-walled steel plate, with an oil stabilizing baffle inside to prevent excessive agitation of the lubricating oil, and an oil drain plug at the bottom to replace the lubricating oil. The main function of the cylinder head is to close the upper part of the cylinder and form a combustion chamber with the top of the piston. The cylinder head has a combustion chamber, a water jacket, a spark plug seat hole (diesel engine has an injector mounting hole), an intake and exhaust port, a valve seat, a valve guide seat hole, etc.

The upper part is equipped with a rocker shaft assembly, which is closed by a cylinder head cover, and the sealing point gasket is installed between the joint surfaces. The cylinder head of a gasoline engine is generally monolithic, but there are some exceptions, such as the two cylinder heads of the EQ6100-1 engine. Diesel engines with larger bore adopt one cylinder and one head or two cylinders and one head, and no more than three cylinders and one head at most, to prevent the cylinder head from deforming.

Cylinder gaskets, commonly known as cylinder blocks, are installed between the cylinder head and the cylinder block, and their function is to seal the joint surface of the cylinder block and cylinder head to prevent air leakage, coolant leakage and oil leakage. The cylinder head gasket is mostly made of asbestos board, some are asbestos boards with copper or iron sheets on both sides, and some are latex asbestos boards with good adaptability on both sides of the middle steel plate. The combustion chamber holes are covered with a double or single layer of metal to prevent the combustion gases from damaging the asbestos layer.

Operating procedures of CNC punching machine:

1. CNC punch operators must undergo the necessary training and be familiar with the mechanical properties of the equipment.

And the working principle, people who do not understand the work of CNC punch are not allowed to use and operate CNC punch.

2.Before the operator works on the synchronous CNC punch, he must make detailed preparations, including checking whether the lubrication system is normal, whether the mechanical properties meet the requirements, whether the electrical equipment is normal, and before the stamping work, the no-load operation must be started to check, and everything is normal before being put into work.

3.The operator must be full of energy and concentrate when working, if he feels mentally tired and difficult to adapt to the work, he should take a proper rest and not work reluctantly. Shouting.

Stamping process because of the traditional machining than the traditional machining material saving, high efficiency, the operator technical requirements are not high, can be made through a variety of molds blanking, punching, forming, drawing, dressing, fine blanking, shaping, riveting and extrusion and other stamping workpieces, due to the above advantages of stamping is more and more widely used. However, improper use of stamping equipment may lead to safety accidents, and the following is a brief introduction to the problems that need to be paid attention to in the use of stamping equipment

1) Before use, check whether the punch guard is complete and whether the flywheel runs smoothly. Whether the upper part and both sides of the foot pedal device are protected, whether the operation is reliable and flexible, and remove the objects that hinder the operation in the work site.

2) Before starting, the plate needs to be inspected to ensure that the stamping oil completely covers the processing part. And there is no foreign matter or cracking on the surface of the plate, so as to prevent the foreign body from popping up during the processing process and endangering the safety of personnel.

3) When more than two people operate, attention should be paid to coordination and cooperation, and the transmission parts exposed to the press must be installed with a protective cover, and it is forbidden to drive or test the car in the case of removing the protective cover, and if necessary, you can drive an empty car test. The installation mold must open the slider to the bottom dead center, the closing height must be correct, the eccentric load must be avoided as much as possible, and the mold must be fastened firmly and checked by pressure test.

4) Pay attention when using, and it is strictly forbidden to put hands and tools and other objects into the danger zone. If it is found that the press is running abnormally or has abnormal sound, the feeding should be stopped to check the cause. After each workpiece, hands or feet must be removed from the button or pedal to prevent misoperation.

5) The punching force must be verified, and overload operation is strictly prohibited. The mold installation must be firm and reliable, and the power supply must be cut off before installing and disassembling the mold. When adjusting the height of use, it is carried out gradually by manual or dynamic methods, and it is forbidden to connect to the car until the adjustment is confirmed.

6) When operating, it is strictly forbidden to talk and do at the same time, and cooperate with each other to ensure safe operation. Generally, it is forbidden for more than two people to operate the punch at the same time, if necessary, there must be a special person to command and be responsible for the operation of the foot pedal device, and any part of the body is strictly forbidden to carry out the mold range feeding and unloading, and there should be special tools.

7) It is forbidden to punch the interlayer feeding, and the second feeding can only be carried out after the front punch or the remaining material must be removed. The installation of the mold must be checked regularly, if there is looseness or slippage, it should be adjusted in time, and the mold must be disassembled in the clamping state.

8) In the formal punching process, because the static difference rate of the main motor changes with different loads, when punching different parts, the electromagnetic counter arranged on the control board can be used to correct the speed.

9) After use, the mold and punch should be wiped clean and ready, and the mold should be dropped before getting off work, the power supply should be disconnected, and the necessary cleaning should be carried out.

The above is the matters that personnel need to pay attention to when using the punch, and the strictly forbidden process can effectively improve efficiency and avoid accidents.

1.Punch workers must learn, master the structure and performance of the equipment, be familiar with the operating procedures and obtain operating permission before they can operate independently.

2.Correctly use the safety protection and control devices on the equipment, and do not disassemble them arbitrarily.

3.Check whether the transmission, connection, lubrication and other parts of the machine tool and the protective safety device are normal, and the screws for the mold must be firm and must not be moved.

4.The machine tool should be run dry for 2-3 minutes before work, check the flexibility of the control devices such as foot brakes, and confirm that it is normal before it can be used, and it should not be operated with illness.

5.The mold should be firm and firm, the upper and lower molds should be aligned to ensure that the position is correct, and the machine tool should be moved by hand to test punch (empty car) to ensure that the mold works in good condition.

6.Pay attention to lubrication before driving, and remove any floating items on the bed.

7.When the punch is taken or in the operation of the punch, the operator should stand properly, keep a certain distance between the hand and the head of the punch, and always pay attention to the punch action, and it is strictly forbidden to chat with others.

8.When punching or obscene short workpieces, special tools should be used, and materials should not be fed or picked up directly by hand.

9.When punching or obscene long-body parts, safety support racks or other safety measures should be taken to avoid digging injuries.

10.When rushing alone, the hands and feet are not allowed to be placed on the hands and feet brakes, and they must be moved (stepped) once to prevent accidents.

11.When more than two people operate together, the person responsible for moving (stepping) the gate must pay attention to the action of the feeder, and it is strictly forbidden to pick up the piece while moving (stepping) the gate.

12.At the end of the work, stop the car in time, cut off the power supply, wipe the machine tool, and tidy up the environment.
