What are the characteristics and uses of hydraulic presses?

The hydraulic press with direct drive of the hydraulic press pump has the following characteristics:

1. The travel speed of the movable beam of the hydraulic press depends on the liquid supply of the pump, and has nothing to do with the deformation resistance of the forging in the process. If the liquid supply volume of the pump is constant, the working speed of the hydraulic press is a fixed value.

2. The liquid supply pressure and power consumed by the pump are related to the deformation resistance of the workpiece to be processed, and the working deformation resistance is large, and the liquid supply pressure and power consumed by the pump are also large, and vice versa is small.

3. The characteristics of constant stroke speed of the movable beam and the change of the pump supply pressure can be used as the signal to operate the distributor to realize the automatic control of the hydraulic press.

4. The basic investment is low, the area is small, and the daily maintenance and maintenance are simple. The hydraulic pumps in the direct transmission system of the pump are selected according to the maximum working speed and working pressure of the hydraulic press, and the hydraulic pump is not fully utilized when the liquid filling stroke, return stroke, auxiliary process and the required working pressure are small, especially the large-tonnage hydraulic press, and its utilization coefficient is very low. Therefore, the hydraulic press tends to carry out the graded transmission of the working speed and working pressure.

Hydraulic press use:

It is widely used in the processing of spare parts in the automotive industry and the setting, punching, correction and shoemaking, handbags, rubber, molds, shafts, bushing parts of the press-fitting, embossing and forming, bending, embossing, sleeve stretching and other processes of plate parts, washing machines, electric motors, automobile motors, air conditioning motors, micro motors, servo motors, wheel manufacturing, shock absorbers, motorcycles and machinery and other industries.

Hydraulic press (a kind of hydraulic press) is a kind of special hydraulic oil as the working medium, through the hydraulic pump as the power source, by the force of the pump to make the hydraulic oil enter the cylinder piston through the hydraulic pipeline, and then the cylinder piston has several groups of seals that cooperate with each other, the seals in different positions are different, but they all play the role of sealing, so that the hydraulic oil can not leak. Finally, through the check valve, the hydraulic oil is circulated in the oil tank, and the cylinder piston circulates to do work, so as to complete a certain mechanical action as a kind of machinery for productivity.

Scope of application:1Embossing, forming, shallow drawing, shaping and pressure assembly of metal or non-metal parts;

2.Glasses, locks and hardware parts pressing, electronic connectors, electrical parts, motor turning, stator pressing, etc.

3.It is especially suitable for mobile phone button punching, silicon steel sheet shaping, burr treatment, bearing pressing, etc.

Presses can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. It is processed into a part by applying strong pressure to the metal blank to cause the metal to plastically deform and break.

The open fixed table press is a general press for sheet metal stamping, suitable for punching blanking, bending, folding and shallow drawing and other stamping work, and has a wide range of applications in watches, toys, tableware, telecommunication equipment, instrumentation, motors, electrical appliances, tractors and automobile manufacturing, daily hardware, radio components and other industries.

Mechanics. The press is driven by the motor through the transmission mechanism to drive the working mechanism, and the process force is applied to the workpiece. The transmission mechanism is a belt drive, gear drive deceleration mechanism; The working mechanism is divided into a screw mechanism, a crank connecting rod mechanism and a hydraulic cylinder.

Presses are divided into three categories: screw presses, crank presses and hydraulic presses. Crank presses are also known as mechanical presses.

The screw press has no fixed dead center, and for larger die forgings, it can be hit and formed many times, and can be singled, continuous and inch-moving. The striking force is related to the amount of deformation of the workpiece, the striking force is small when the deformation is large, and the striking force is large when the deformation is small (such as cold blow). In these respects, it is similar to a forging hammer.

But its striking force is closed through the frame, so it works smoothly, the vibration is much smaller than that of a forging hammer, and it does not require a large foundation.

The lower part of the press is equipped with a forging ejector. The screw press has the functions of a variety of forging machinery such as die forging hammer and mechanical press, and has strong versatility and can be used for die forging, blanking, drawing and other processes. In addition, the screw press has a simple structure and is easy to manufacture, so it is widely used.

The press is a kind of general equipment, which refers to the mechanical work tools that realize the pressure through energy conversion under the action of mechanical pressure, in fact, the most important function is to liberate manpower from heavy physical labor, and then it is to use mechanical principles to complete the pressure that cannot be completed by manpower.

Uses and classification of presses::

A press is a device used to provide power and movement for the material in a mold to achieve pressure processing. Crank presses belong to the mechanical transmission type of presses. It is an important pressure processing equipment, which can carry out various stamping processes and directly produce semi-finished products or products.

Therefore, crank presses are widely used in the industrial sectors of automobiles, agricultural machinery, electrical appliances, instrumentation electronics, medical machinery, defense, aerospace and daily necessities.

In order to adapt to the process requirements of different parts, various types of crank presses are used in production, which have their own unique structural forms and characteristics. Crank presses can usually be classified according to their process use and structural characteristics.

According to the process use, crank presses can be divided into two categories: general purpose presses and special presses. General purpose presses are suitable for a variety of process uses, such as blanking, bending, forming, shallow drawing, etc.; The special press has a single purpose, such as deep drawing pressure peach, sheet metal bending machine, plate machine, cold automatic machine, high-speed press, meal press, hot chess suction press. All belong to special presses.

The working principle of the press The main working principle of the press is to convert the existing energy into mechanical kinetic energy through transportation, act on the forming slider, and act on the operating object to form or shape the final work through the slider. Through the crank slider mechanism of the system, the motor is promoted to rotate, and in the process of rotation movement, the slider is promoted to carry out the reciprocating linear motion up and down, through such movement, the blank is acted, and then the forming processing of the blank is carried out, and the press belongs to a kind of machinery with forging function. Because the press is the use of mechanical pressure, so the action tomorrow obvious jitter is very stable, and the work is very reliable, so it is widely used in production practice, especially in the stamping or extrusion industry, which is more difficult to achieve by manpower, and other metallurgical work processes are widely used, and it is precisely because of this practicability, so the number of mechanical presses used in production practice is the largest, basically more than half of the total number can be pointed, which is the principle of the press.
