High-efficiency environment-friendly rolling production method for automobile shaft parts

Abstract

The invention provides a high-efficiency environment-friendly rolling production method for automobile shaft parts, and belongs to the technical field of rolling production of shaft parts. An upper roller, a rolled part, a lower roller, an upper roller forming wedge, a lower roller forming wedge, an upper roller cut-off edge, a lower roller cut-off edge and a wedge inclined groove are included; the upper roller is fixedly arranged at a wedge rolling upper end; the upper roller is provided with the upper roller forming wedge; the lower roller is fixedly arranged at a wedge rolling lower end; the lower roller is provided with the lower roller forming wedge; the rolled part is subjected to middle induction furnace heating to 1150 DEG C and then cut; the upper roller cut-off edge is fixedly arranged at the left end of the upper roller end surface and is arranged on the end side of the upper roller forming wedge; and the lower roller cut-off edge is fixedly arranged at the right end of thelower roller end surface and is arranged at the side end of the lower roller forming wedge. Through the oblique rolling continuous forming process, shaft parts with low draw ratio are precisely formed, mold design is simple, and production can be conducted continuously in batch.

Description

technical field [0001] The invention relates to a rolling production technology of shaft parts, in particular to a high-efficiency green rolling production method of shaft parts for automobiles. Background technique [0002] Part rolling technology is an advanced technology for plastic forming of shaft parts. The oblique rolling process is more suitable for shaft parts with relatively short length-to-diameter ratio. When designing the mold, it is necessary to accurately calculate the materials contained in each section of the mold cavity. Due to the complex spatial relationship, this will be a very difficult thing, especially when trying to accurately form products with complex shapes. In addition, the skew rolling process cannot adjust the axis inside the rolled piece during skew rolling. In some cases, it is easy to loosen the core of the product. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be ...
