Raschig ring one-step forming die

Abstract

The invention relates to a Raschig ring one-step forming die which comprises an upper die and a lower die. The surface, close to the lower die, of the upper die is detachably and fixedly connected toa forming die, and extrusion mechanisms for laminating a stainless steel plate to the forming die are separately arranged on the left and right sides of the forming die. A forming groove where the forming die is embedded is formed in the lower die, a sliding bar is arranged at the bottom of the forming groove, the sliding bar is elastically and slidably arranged in the lower die, one end of the sliding bar penetrates from the lower die, a stroke switch is arranged below the other end of the sliding bar, the stroke switch is in control connection to the extrusion mechanisms, a cutting device isarranged on one side of the forming die, and the cutting device is fixed to the surface, close to the lower die, of the upper die. A Raschig ring is formed in one step in the whole punching process,so that the Raschig ring one-step forming die is simple and skillful in structure, and the production efficiency is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a Raschig ring primary forming mold. Background technique [0002] Raschig ring is a kind of filler, which can resist the corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid. It can be used in various high and low occasions, and its application range is very wide. [0003] In the prior art, such as the Chinese patent whose publication number is CN209318578U, it discloses a Raschig ring forming mold, which includes an upper mold box body and a lower mold box body, and the bottom of the upper mold box body is sequentially provided with an upper mold box body from left to right. Cutting knife, pre-bending upper die, drawing U upper die and round pressing upper die, the lower die box body is a cavity, and its top, bottom and right side are all openings, the bottom of the lower die box body is fixed with a bottom plate, the lower die The ba...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the above-mentioned patent is used to produce metal Raschig rings, four processing procedures are required: cutting, pre-bending, U-drawing and rounding, and the entire production process takes a long time , Time-consuming and labor-intensive, reducing production efficiency, therefore, there is an urgent need for a mold that can process Raschig rings at one time
