Pneumatic press in the production process stamping process belongs to the traditional mechanical processing, there are savings in materials and energy, high efficiency, the operator's technical requirements are not high, through a variety of moulds can be made through the application of mechanical processing can not be achieved by the product of these advantages, and therefore it is more and more widely used, and the future of the punching machine industry will be developed in the direction of intelligence.
Machinery industry analysts pointed out that: China's punch press manufacturers produce the basic characteristics of the punch press are mainly two, one is the rigidity, which includes longitudinal rigidity - the slider and the workbench of the arch and the elastic elongation of the frame; and transverse rigidity - eccentric loads affecting the lower slider's horizontal displacement; and the second is the slider's movement characteristics, including perpendicularity, parallelism, straightness, etc., which have a great influence on the accuracy of the product. The precision of the product is not only related to the press, it is related to the material, mould, lubrication and so on, and cannot be considered only one factor.
Considering the elements of pneumatic punching machine, the accuracy of the thickness direction of the product is related to the longitudinal rigidity, while the deviation, bending or parallelism is related to the transverse rigidity and the characteristics of the motion curve. Therefore, by improving these characteristics, the product accuracy can be improved, the mould life can be extended, and the stability of production can be improved. Mechanical presses include the crankshaft press, which is the most widely used in stamping, the elbow-type press, which has the slowest speed near the lower dead centre, and the link-type press, which has a high torque capacity and starts to slow down when the speed of the slide is very high above the lower dead centre.
Pneumatic presses originally used as general-purpose machines are also pursuing high precision and functionality, resulting in the development of an integrated gantry press; and a link-type press with an AIDA link drive mechanism that is slowed down around the lower dead centre, while the SPM is unaffected.
Add sufficient lubricant to all lubrication points and friction parts. Turn the flywheel by hand so that the flywheel idles for a few revolutions in the state of being disengaged from the clutch. Carefully check that the oil circuit is clear. Check whether the clutch mechanism and the manoeuvring mechanism are normal. Adjust the adjusting nut on the machine board, adjust the tightness and looseness of the triangle belt. After the above preparations, turn the flywheel by hand to make the clutch in the disengaged position, then turn on the motor, manoeuvre the handle by hand, and punch several times in vacuo.
And then carefully check whether the pneumatic press mould installation is accurate, firm, as well as the operation of the ministries, to confirm that everything is normal, you can work. Equipped with a foot pedal device press, electronic control box front panel, with a trip selector switch. According to the needs of the work, set a single or continuous working stroke. The press can be operated by stepping on the foot switch.
High-speed punching machine rotates the flywheel driven by the electric motor to store energy, and then releases the energy of the flywheel instantly through the control of the clutch and brake to drive the slider to carry out high-speed reciprocating motion to realize the punching action.
