Embodiment

[0031] Place the workpiece to be punched on the fixed plate 6, and the extrusion plate 16 squeezes and fixes the punched workpiece. According to the type of blanking, adjust the position of the blade 9, that is, loosen the fastening nut 12, and turn the adjustment pin 10 , the blade slot 24 moves in the blade moving slot 23 and drives the blade 9 to move back and forth. After being adjusted to a suitable position, tighten the fastening nut 12 to fix the blade slot 24 to achieve the purpose of fixing the blade 9.

[0032] Turn on the hydraulic switch 4, the hydraulic cylinder 3 works and drives the stamping plate 2 to carry out the stamping operation.

[0033] Step on the extrusion column 28 downwards, the gas in the U-shaped cylinder 31 pushes the rotating shaft 5 upwards, the limit rod 29 breaks away from the limit groove 8, rotates the fixed plate 6, and adjusts the position of the blanking workpiece; loosen the extrusion column 28 Due to the pressure, the rotating shaft 5 f...

Abstract

The invention discloses an easy-to-adjust refrigerator backplane blanking device. The easy-to-adjust refrigerator backplane blanking device comprises a base and a punching plate, a hydraulic cylinderis connected between the base and the punching plate, a hydraulic switch and a rotating shaft are arranged on the base, a fixed disc is welded to the rotating shaft, four pairwise symmetrical fixed devices are fixed to the side wall of the fixed disc, and a movable blade is arranged at the bottom of the punching plate. According to the easy-to-adjust refrigerator backplane blanking device, the movable blade is additionally arranged, the purpose of adjustable cutting length is realized, the blanking die model is variable, and is suitable for different types of blanking workpieces; and in addition, the fixed disc is rotatably arranged, the blanking position can be rotated, and the working range of a blanking die is expanded.

Description

technical field [0001] The invention relates to a punching device, in particular to a punching device for the back panel of a refrigerator which is easy to adjust, and belongs to the application field of punching equipment. Background technique [0002] Punching is a stamping process that uses a die to separate part of the material or process part from another part of the material, process (process) part or waste. It belongs to the stamping method that separates parts or blanks of the required shape and size from the sheet. Blanking is a general term for separation processes such as shearing, blanking, punching, punching, notching, sectioning, chiseling, edge trimming, tongue cutting, cutting, and trimming. [0003] Punching uses the cutting edge of the die to cause the sheet to shear deformation and separate along a certain contour line, which accounts for the largest proportion in stamping production. In the blanking process, except for the metal near the shear contour li...
