JH21
An open (C-frame) fixed-worktable press with PLC control and a pneumatic double-balance-cylinder system, offering three-side die access for large, heavy dies and automation.
Overview
The open fixed table press adopts imported PLC centralized control, with the air circuit using imported safety double valve control. It can perform inching, single and continuous stamping operations.
The body is welded from high-quality steel plates that have been tempered or vibration aged, then shot blasted, providing good rigidity and stable precision.
The crankshaft features longitudinal placement with a compact structure, rolled construction, good finish and flexible rotation. The rectangular six-sided extended guide rail offers high guiding precision. Pneumatic double balance cylinders balance the weight of the slider and upper die, reducing impact and noise, eliminating gaps between connecting rod and slider and decreasing impact and wear on stressed components while improving forming accuracy.
Key data
Full technical parameters are confirmed together with our engineers, based on your part and production volume.
Features
The open C-shaped machine body provides three-sided access for convenient die loading and operation. Constructed from high-quality cast iron or welded steel, it effectively resists deformation during stamping, ensuring accuracy and die longevity.
The spindle (crankshaft) is ground using high-precision equipment and supported by high-quality double-sealed rolling bearings. The slide uses six- or eight-sided rectangular guideways with extended guide surfaces and precision gap adjustment, enabling precise and smooth movement while significantly reducing die damage from lateral forces — particularly suitable for precision stamping.
The fixed worktable, unlike tilting presses, accommodates large, heavy dies and automated accessories such as robots. Ample space beneath the worktable suits installation of devices like air cushions. Standard safety features include two-handed operation buttons and emergency stop buttons, with optional photoelectric safety devices.
The fixed platform structure integrates seamlessly with automated equipment including automatic feeders, manipulators and three-axis robots, enabling fully automated stamping production lines.
