What is the difference between a punch and a slotting machine, and what is the function of a punch

A punch press is a press that is stamped. In national production, the stamping process is more efficient than traditional machining because it saves materials and energy, and has high efficiency, and the technical requirements for operators are not high. Stamping production is mainly for sheet metals.

Through the mold, it 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.

A slotting machine is a machine tool that uses the vertical reciprocating motion of the inserting cutter to insert keyways and holes. Slotting machines are generally used for inserting single pieces and small batch production of workpieces, including ordinary slotting slots, keyway slots, gantry slotting slotting beds and mobile slotting machines. The ram of the ordinary slotting machine carries the tool holder for the main movement of the up and down reciprocating, and the round table equipped with the workpiece can use the upper and lower seats for longitudinal, transverse and rotary feed movements (see machine tools).

The workbench of the keyway slotting bed is integrated with the bed, and the workpiece is installed on the workbench. The tool holder that extends upwards from the bed through the workpiece hole carries the insertion knife while making the main movement of reciprocating up and down, and the intermittent feed movement at the same time. It is characterized by the fact that the workpiece mounting is not limited by the column like ordinary slotting machines, so it is suitable for machining keyways in the holes of large parts (such as propellers).

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.

A punch press is a press that is stamped.

In national production, the stamping process has the advantages of saving materials and energy compared with traditional machining, high efficiency, low technical requirements for operators 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 the plate, through the Zen reed mold, can make blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion, etc., widely used in various fields. For example, we use switches and sockets, cups, cupboards, plates, computer cases, and even missiles and airplanes, there are a lot of accessories that can be produced through molds with punches.

The main classification of punches

1. From the drive: mechanical and servo punch (servo).

At present, most of the air-fired presses on the market are mechanical presses driven by ordinary motors, with flywheels and clutches, and cannot be freely programmed to set the running speed of the slider and the residence time of any position in a single stroke. The servo punch is driven by a servo motor, without a flywheel and clutch, and can freely program the running speed of the slider and the residence time of any position, and the bottom dead center accuracy is also higher than that of the mechanical punch (can be achieved.

2. From the fuselage: open (C type) and closed (O type).

The open punch is generally below 300t, with a single axis (single point) punch press, the working table is larger, the overall structure is not as stable as the closed punch, and the opening phenomenon is easy to occur during long-term operation, which has a certain impact on the accuracy. For manufacturers with high requirements for product accuracy and stability, especially punches above 300t, closed-structure punches are generally selected. In the closed punch, according to the manufacturer's requirements for the working table and the strength of the punch, it can be divided into one-piece punch and split punch (three-split type).
