Punching machine with multiple copper sleeves and multiple guide columns

Abstract

The invention discloses a punching machine with multiple copper sleeves and multiple guide columns. The punching machine comprises a punching machine body, guide column bodies and copper sleeve bodies, wherein the guide column bodies and the copper sleeve bodies are arranged on the punching machine body, and flow guiding devices which enable the guide column bodies to move stably and conduct dustproof lubrication on the guide column bodies are arranged inside the copper sleeve bodies. According to the punching machine with the multiple copper sleeves and the multiple guide columns, drainage devices are arranged inside the copper sleeve bodies, and therefore, on the one hand, lubricating oil can fully fill the inside of the copper sleeve bodies, meanwhile, the effect of timely oiling the copper sleeve bodies is achieved, and meanwhile, the phenomenon that the lubricating oil inside the copper sleeves is dry and astringent is avoided, and the stamping rate of an upper mold and a lower mold is further improved; and on the other hand, dustproof pieces can effectively prevent large-particle impurities such as dust attached to the outer surfaces of the guide column bodies from entering the inside of the copper sleeves in the moving process of the guide column bodies, and meanwhile, noise during working of the punching machine body is reduced, and the working efficiency of the punching machine body is improved.

Description

technical field [0001] The invention relates to the technical field of punching machines, in particular to a punching machine with multiple copper sleeves and multiple guide columns. Background technique [0002] Punch presses are widely used in stamping and forming of hardware parts such as electronics, communications, computers, household appliances, furniture, vehicles, automobiles, motorcycles, bicycles, etc. [0003] The design principle of the punching machine is to convert the circular motion into a linear motion. The main motor drives the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to achieve the linear motion of the slider. From the main motor to the The movement of the connecting rod is a circular motion, and there needs to be a transition point between the circular motion and the linear motion between the connecting rod and the slider. There are roughly two types of mechanisms in its design, one is a ball type, an...
