At present, the press working in the machining process plays an important role in the processing industry of national economy. The application field of sheet metal parts is extremely wide, and extends into various aspects of the manufacturing industry, and the plate forming is mainly realized through a pressurizing and stamping die. The stamping process has the advantages of high precision, high efficiency, good quality, cost saving, material and energy saving and the like.

In the existing punching machine, a motor drives a flywheel, and a transmission gear drives a crank-link mechanism to enable a sliding block to move up and down through a clutch so as to drive a drawing die to form a steel plate. The double-acting means that the press is provided with two slide blocks which are an inner slide block and an outer slide block, the inner slide block drives a male die or a female die of the die, the outer slide block drives a blank holder on the die, the blank holder firstly acts to press the edge of a steel plate during drawing, and the inner slide block then acts to draw. The design principle is that the circular motion is converted into linear motion, the main motor drives the flywheel, the gear, the crankshaft (or eccentric gear), the connecting rod and the like are driven to rotate through the clutch to achieve the linear motion of the sliding block, and the motion from the main motor to the connecting rod is circular motion. The connecting rod and the sliding block need to have a transfer point of circular motion and linear motion, and the design of the connecting rod and the sliding block is roughly provided with two mechanisms, one is spherical, and the other is pin-shaped (cylindrical), and the circular motion is converted into the linear motion of the sliding block through the mechanism. Since the press machine applies pressure to the material to plastically deform the material to obtain a desired shape and accuracy, it is necessary to fit a set of dies (divided into an upper die and a lower die) with the material interposed therebetween, to apply pressure by the machine to deform the material, and to absorb a reaction force caused by a force applied to the material during the process by a machine body of the press machine.

At present, people have higher and higher requirements on the precision of mechanical manufacturing, the precision requirement of a punching machine is improved along with the requirement, but the manufacturing precision is reduced due to the thermal expansion effect and the like caused by the temperature change generated in the punching machine during use, and further the production efficiency is reduced.
