The connecting rod parts of the slider body are connected by screw rods and are in plane contact, instead of the traditional ball head and bowl structure. There is no gap in stamping and high repeat positioning accuracy.
The connecting rod piece, crankshaft and flywheel drive all adopt the precision rolling bearing structure, and the operation is stable. The closed bearing does not need to be refueled frequently in the working state, and the machine is clean and tidy.
Clutch parts are designed in the fuselage to seal the inner cavity independently, with low noise and low leakage during operation, which is beneficial to environmental protection and clean production.
The fuselage is made of high-strength gray cast iron, and after internal stress is eliminated, the accuracy is stable for a long time. Various punching machines can be configured for automatic punching lines.
