High-precision and high-stability punch press
By adopting alloy steel with a low coefficient of thermal expansion and sliding layer material with a low coefficient of friction, optimizing the transmission mechanism and guiding structure, and combining it with a constant temperature lubrication oil circuit and air cushion anti-vibration feet, the problems of thermal stability, guiding accuracy and vibration reduction and leveling of existing punch presses have been solved, and high-precision and high-stability punch press operation has been achieved.

Abstract
The application relates to the field of mechanical pressure processing equipment, and provides a high-precision and high-stability punch. The punch comprises a machine body, a crankshaft, two sliders, a counterweight, a sliding block, an upper connecting rod, a lower connecting rod and a driving connecting rod. The crankshaft is arranged on the machine body; the sliders are arranged on the two sides of a transmission mechanism and horizontally slide with the machine body; the counterweight vertically slides with a top base above the transmission mechanism; the sliding block is arranged below the transmission mechanism and is used for mounting an upper die. The upper connecting rod connects the counterweight and the slider, the lower connecting rod connects the sliding block and the slider, and the driving connecting rod connects the crankshaft and the slider. The second ends of the three connecting rods are coaxially hinged with the slider through the same rotating shaft. The scheme effectively reduces vibration and friction, and improves the precision and stability of the punch.
