The punch press is a stamping press. 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 cannot be achieved by machining through various mold applications. Its use is more and more extensive. The difference between hydraulic press and ordinary punch:
1. The ordinary punching machine is driven by a belt type motor, the belt is easy to wear, and the rotation of the rotating wheel has a certain influence on the operator.
2. The general punching machine is straight and pressed, and the action mode of this kind is quite large, but at the same time, the hardness requirement of the mold is higher, the impact force is large, and the damage to the mold may be greater.
3. The hydraulic press adopts a four-column and three-plate structure. The friction coefficient from the power system can be minimized, and the punch can maintain considerable accuracy during long-term operation. The mold life is extended.
4. The ordinary punching machine adopts the straight-through type, and has no controllability for the pressing. The power of the Tianjin hydraulic press can be adjusted freely.
5, ordinary punching machine is generally direct punching, such work noise will be relatively large, Suzhou hydraulic press is the use of controllable speed stamping decibel is much smaller.
6. In combination, the strength of the ordinary punching machine is not adjustable, and the hydraulic press has an adjustable pressure. The stroke of the ordinary punching machine is not arbitrarily controlled, and the hydraulic press has an arbitrary limit of the stroke limit.
Hydraulic press and ordinary punch configuration; hydraulic press configuration: hydraulic drive is a transmission method that uses liquid pressure to transmit power and control.
The hydraulic unit is composed of a hydraulic pump, a hydraulic cylinder, a hydraulic control valve and hydraulic auxiliary components. Auxiliary components: 1, fuel tank: used to store oil, heat. Separation of air and impurities in oil 2, tubing and tubing joint 3, oil filter 4, pressure gauge 5, sealing element
The configuration of ordinary punching machine: switch, button, electric box, belt, wheel, motor, template, fuselage, is a kind of output method that generates pressure by the motor to drive the belt to pull the wheel and press it down. It is a kind of traditional and long-lasting use. Stamping machinery.
