A kind of semi-shaft shrink rod production process and its production equipment

Abstract

The invention provides a production process and production equipment for a half shaft contracting rod. The production process for a half shaft contracting rod disclosed in the invention mainly comprises the following steps: clamping and fixing a horizontally arranged blank in a vertical direction and making the blank to be upright; transversely fixing the blank relative to the tail part of the blank at a horizontal direction; allowing a contracting rod die corresponding to a half shaft to be produced to move relative to the head of the blank in the horizontal direction and pressing the head of the blank into the contracting rod die; loosening the blank in the vertical direction after complete pressing is realized; and applying a pulling force on the tail part of the blank at a horizontal direction to pull out the blank which has become a semi-finished product of the half shaft through plastic deformation from the contracting rod die. The invention also provides a half shaft contracting rod machine used in the production process for the half shaft contracting rod. The machine comprises a frame, the contracting rod die, a clamping and straightening mechanism, a remolding device and a power installation. The production process and the production equipment for the half shaft contracting rod have the characteristics of high work efficiency, reliable quality of produced products and the like.

Description

technical field [0001] The invention relates to a process and equipment for producing a half shaft, in particular to a half shaft shrinking process and a half shaft shrinking machine. Background technique [0002] At present, forging methods such as flat forging or swing rolling are mainly used for the production of half shafts at home and abroad. When using these forging methods to produce half shafts, it usually needs to go through multiple steps such as gathering materials, pre-forging, final forging, and then performing multiple steps such as turning around, upsetting the tail and trimming. process, and each process needs to be equipped with corresponding equipment and molds; in addition, the forging method is used to produce the half shaft, the forged part must be rough machined and then finished, and the thin rod part must also be turned. Therefore, in the prior art, the consumption of materials for the production of half shafts is relatively large, and the process is ...
