The stamping process of pneumatic punching machines in the production process belongs to traditional mechanical processing, which has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that mechanical processing cannot achieve through various mold applications. Therefore, its use is becoming increasingly widespread, and the future punching machine industry will develop towards intelligence.
Mechanical industry analysts point out that the basic characteristics of punching machines produced by Chinese punching machine manufacturers mainly include two aspects: first, rigidity, which includes longitudinal rigidity - the arch between the slider and the workbench and the elastic elongation of the frame; And the horizontal displacement of the slider under the influence of lateral rigidity - eccentric load; The second is the motion characteristics of the slider, including verticality, parallelism, straightness, etc., which have a significant impact on the accuracy of the product. The accuracy of a product is not only related to the punching machine, but also to materials, molds, lubrication, and other factors, and cannot be solely considered.
From the perspective of the elements of pneumatic punching machines, the accuracy of the thickness direction of the product is related to longitudinal rigidity, while deviation, bending or parallelism are related to transverse rigidity and motion curve characteristics. So by improving these characteristics, product accuracy can be improved, mold life can be extended, and production stability can also be improved. Mechanical punching machines include the most widely used crankshaft type punching machines in stamping processing, the elbow type punching machines with the slowest speed near the bottom dead center, and the connecting rod type punching machines with high torque capacity, where the slider speed starts to slow down from a high position above the bottom dead center.
The pneumatic punch press, originally used as a general-purpose machine, also pursues high precision and high functionality, thus developing a one-piece gantry punch press; A linkage punch with AIDA linkage driving mechanism and slow speed near the bottom dead center without affecting SPM.
Add sufficient lubricating oil to all lubrication points and friction parts. Rotate the flywheel by hand, allowing it to spin a few laps without engaging the clutch. Carefully check if the oil circuit is unobstructed. Check if the clutch mechanism and control mechanism are functioning properly. Adjust the tightness of the V-belt by adjusting the nut on the machine board. After the above preparation work, rotate the flywheel by hand to put the clutch in the disengaged position, then start the motor, operate the handle by hand, and perform a few empty strokes.
Carefully check whether the installation of the pneumatic punching machine mold is accurate and firm, as well as the operation of each part, and confirm that everything is normal before proceeding with work. A press equipped with a foot pedal device is equipped with a travel selection switch on the front panel of the electronic control box. According to work needs, set any single or continuous work itinerary. Step on the foot switch to operate.
