A kind of dough hook cold-bending forming device and its process

Abstract

The invention discloses a cold bending molding device and process for a dough kneading hook. The cold bending molding device comprises system components such as a demoulding device, a material returning device, a compressing device, a speed change drive device, and an arc molding die. Compared with prior art, the cold bending molding device and process for a dough kneading hook have the beneficial effects that a mechanical molding principle is used to mold round steel into a required three dimensional irregular-shaped effect at one step. The structure is simple, the round steel is directly used for molding, direct cold bending molding without any heating is realized in a production process, the "rigidity" of raw materials is kept, and the molding process for larger-scale three dimensional irregular-shaped products (the raw materials are too hard) is realized. The cold bending molding device and process are simple in operation and suitable for promotion and use.

Description

technical field [0001] The invention relates to a forming process, in particular to a dough hook cold-bending forming device and its process. Background technique [0002] Current production process: traditional process is divided into two types, a precision casting or casting, the disadvantages are 1. The internal structure of the product has air holes and blisters (determined by the process) and will break during use; 2. The installation part cannot be "truly round" As a result, the stirring hook cannot be completely fixed tightly, and it will loosen after a long time; 3. The cast product has a large amount of deformation, and it needs to be reshaped many times to achieve the use effect or even barely achieve the use effect. b. The disadvantage of hot bending process is that the product is produced by heating. After heating, the raw material loses its original "steelness". During use, it will be deformed under the action of external force and cannot be used, resulting in a...

B hot bending process production, the disadvantage is that the product is produced by heating, the raw material loses its original "steelness" after heating, and will be deformed under the action of external force during use and cannot be used, resulting in a greatly shortened service life of the product
