Embodiment Construction

[0009] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0010] as attached figure 2 As shown, the steps of a continuous punching precision forming method for automobile cage parts are: a. The first step: punching the inner hole → b. The second step: thinning / extruding the protrusion → c. Three working steps: forging the boss → d. The fourth working step: punching through the boss hole / punching the inner hole / blanking.

[0011] The first step: punching the inner hole. The feeding roller sends the strip material to the first working step, and the slider of the press moves down to punch out the inner hole. The hole can play the role of radial diversion of material during the second step of flattening / extruding the protrusion, so that the material flow due to thinning can gather towards the inner hole, which can reduce the deformation of the strip material periphery.

[0012] The seco...

Abstract

The invention provides a continuous stamp forging precise forming process of an automobile retaining frame part and belongs to the field of metal pressure processing. The process adopts the process route that a forming process method of combining precise stamping and cold forging is adopted, an annealed steel plate with the thickness a little greater than the thickness of a part flange part is selected as raw materials, after uncoiling and flattening work procedures, the steel plate is clamped by a feeding roller and is conveyed into a multi-station stamp forging forming mold, workpieces are formed in four steps, the four steps respectively comprise the first work step of inner hole blanking, the second work step of flattening / bulge extrusion, the third work step of hole extrusion and bulge forming and the fourth work step of bulge hole punching / inner hole punching / blanking, and the workpieces are obtained. The parts obtained by adopting the process do not need the subsequent machining at all. Compared with the traditional forging process, the continuous stamp forging precise forming process has the advantages that the precision of the forged piece is improved, the efficient and continuous production of retaining frame part products is realized, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a precision forming method, in particular to a continuous stamping and forging precision forming process for automobile cage parts, which belongs to the field of metal pressure processing. Background technique [0002] At present, in the world's metal pressure processing industry, production efficiency has become the core factor of the market competitiveness of enterprises. In order to improve production efficiency, the production method of multi-station continuous forming is being widely used. More and more fields such as automobiles, aerospace, machinery, etc. The manufacturing of parts adopts the automatic continuous forging production method, and the production efficiency has been greatly improved. attached figure 1 The shown is a cage part widely used in the automotive industry. The part is in the shape of a ring flange as a whole. The upper and lower end faces of the flange have higher flatness requirements, and there ar...
