Punching device for stainless steel machining

Abstract

The invention discloses a punching device for stainless steel machining. The punching device for stainless steel machining comprises a lower die box, wherein a working area is arranged inside the lower die box, a push plate is slidably connected to the lower die box, sliding grooves are formed in the two sides below the push plate, rolling wheels are fixedly connected to the two sides of the lowerend face of the push plate, a sliding plate is slidably connected to the interior of the push plate, an annular die is fixedly connected to the upper end face of the sliding plate, a discharging groove is formed above the working area, a discharging plate is slidably connected to the interior of the discharging groove, fixing rods are fixedly connected to the four corners of the upper end face ofthe lower die box, an upper die box is slidably connected to the fixing rods, a punch is fixedly connected to the middle of the lower end face of the upper die box, an annular groove is formed in theouter ring of the punch, a punching ring is slidably connected to the punch, piston rods are fixedly connected to the two sides of the upper end face of the upper die box, a hydraulic box is fixedlyconnected to the upper end faces of the fixing rods, a piston groove is formed in the hydraulic box, a connecting pipe is fixedly connected to the hydraulic box, and the connecting pipe is fixedly connected with a hydraulic press. The punching device for stainless steel machining is convenient in operation, and can freely adjust the size of the punch and the size of a die hole.

Description

technical field [0001] The invention relates to the technical field of punching devices, in particular to a punching device for stainless steel processing. Background technique [0002] In factory production, it is often necessary to process stainless steel parts, and a punching device is used for punching. The existing punching device usually includes an upper die and a lower die matching the upper die, and the stainless steel parts are placed on the lower die. On the hole of the lower die, the punch of the upper die is pressed down to punch the stainless steel part, and for the thinner stainless steel part, the punch needs to be the same size as the hole of the lower die. [0003] However, at present, the existing punching device cannot freely switch the size of the punch and the lower die hole. When punching stainless steel parts with different sizes, it is often necessary to use multiple punching devices or replace the upper die and lower die. The process is extremely c...
