Refrigerator door stamping device with locating groove

Abstract

The invention discloses a refrigerator door stamping device with a locating groove. The refrigerator door stamping device comprises a base; vertically-placed supporting plates are welded on the two sides of the top of the base correspondingly; horizontally-placed connecting plates are welded on the tops of the two supporting plates; vertically-arranged sliding rails are welded on the inner side walls of the two supporting plates correspondingly; sliding blocks are slidably mounted on the two sliding rails; connecting rods are welded on the tops of the sliding blocks; and upper stamping moulds are fixed at the bottoms of the sliding blocks through fastening bolts. The locating groove is formed in the middle of the top of the base; a limiting groove is formed in the bottom of the locating groove; a buffering groove is formed in the bottom of the limiting groove; a plurality of buffering devices are fixed to the bottom of the buffering groove in a rectangular array mode; and a lower stamping mould is mounted in the limiting groove. Through the design of hydraulic cylinders, the impact depth of an impact block can be controlled to adjust the depths of different refrigerator doors, because the needed impact depths for different types of refrigerator doors are not the same.

Description

technical field [0001] The invention relates to the technical field of punching devices, in particular to a refrigerator door punching device with positioning grooves. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. For a long time, the development of China's mold industry has been uneven in geographical distribution. The development of the southeastern coastal areas is faster than that of the central and western regions, and the development of the south is faster than that of the north. The most concentrated areas of mold production are in the Pearl River Delta and Yangtz...

Problems solved by technology

[0003] Patent application publication number: CN 103028660 A proposes a stamping device for positioning and processing workpieces, which includes a fixed assembly, a linkage mechanism, a force application assembly, and a stamping component. The force application assembly is rotatably connected to the fixed assembly. The stamping device It is not suitable for the stamping of refrigerator doors. The positioning effect of the device is not very good. The upper stamping die and the lower stamping die of the existing stamping device are independently separated, so deviations are prone to occur during stamping. The buffering effect of the existing stamping device Not very good, the mold is easy to be damaged, so this invention proposes a refrigerator door stamping device with positioning grooves to solve the above problems
