The main components of the press include the following: Machine body, Transmission, Clutch, Slider, Brake, Control mechanism.
1. Machine body
The body of J23 J21 power press machine is a C-shape integral casting part, and features a workbench with a rectangular hole in the center to allow completed workpieces or scrap pieces to easily fall through. The pad is bolted to the work bench, with a T groove installed on the pad to facilitate die installation.
The transmission system is powered using a motor mounted on the back of the fuselage.
The clutch is positioned at the right end of the crankshaft. The turn-button of the clutch is woodruff key, which uses the force of extension spring to remain the turn-button at a normally open status.
The slider is located between the fuselage guideway. The slider moves straight up and down in the V-groove of the guide rail using the crankshaft rotary motion.
The brake wheel is circular and attached on the left end of the crankshaft. It is a continuous brake, with the belt made using a soft steel leather, or internal riveted copper asbestos brake tape.
6. Control mechanism
This machine uses a mechanical manipulation mechanism to control the slider for single punching with a foot lever.
