Shape-protecting fine stamping die for refrigerator stamping part

Abstract

The invention belongs to the field of refrigerator part production, and particularly discloses a shape-protecting fine stamping die for a refrigerator stamping part. The shape-protecting fine stampingdie comprises a workbench. A top plate is arranged above the workbench, the two ends of the sides, close to each other, of the workbench and the top plate are fixedly connected through supporting columns, a female die is fixedly connected to the center of the top side of the workbench, a connecting plate is slidably arranged between the two supporting columns, a male die is fixedly connected to the center of the bottom side of the connecting plate, a convex block is arranged at the center of the bottom side of the male die, connecting rods are symmetrically slidably connected to the two endsof the bottom side of the male die, the top ends of the connecting rods slidably penetrate through the connecting plate and extend to the upper portion of the connecting plate to be fixedly connectedwith clamping blocks, and a pressing plate is fixedly connected between the bottom ends of the two connecting rods. According to the shape-protecting fine stamping die, through the design of the connecting rods, the pressing plate, springs, screw rods and side plates, the stamping part can be preliminarily fixed before stamping, the stamping part can be further fixed during stamping, and the deformation of the stamping part is avoided.

Description

technical field [0001] The invention relates to the technical field of refrigerator parts production, in particular to a shape-protecting fine-blanking die for refrigerator stamping parts. Background technique [0002] Typical structures of fine punching dies include active convex mode structure, fixed convex mode structure and continuous fine punching die. The fine blanking process requires accurate blanking force, blank holder force and back pressure of the fine blanking equipment. Therefore, mechanical fine-blanking presses are generally used for mass production of fine-blanking parts, but the investment cost of mechanical press equipment is high, so many manufacturers use hydraulic mold frames to fine-blank parts on hydraulic presses. The cost of the hydraulic press is low, and it is suitable for the production of fine blanking parts of various varieties and small and medium batches.

Problems solved by technology

[0003] In the production process of refrigerator stamping parts, in order to ensure its accuracy, fine blanking dies are often used to make them, but the existing fine blanking dies lack protection for stamping parts when they are working, which makes the stamping parts prone to accidents during stamping. The denaturation of stamping parts, so we designed a shape-protecting fine-blanking die for refrigerator stamping parts to solve the above problems
