Bush forging technology

Abstract

The invention discloses a bush forging technology, including the following steps of: 1, chamfering one end of a steel ingot workblank, pressing feeder head at the other end to form pincers handles, cutting off excessive length, cutting water gap, and burring; 2, vertically placing the workblank into an upsetting plate part in a mold; 3, taking out the mold, punching a through hole by using a punch; 5, leveling the end face, penetrating a rod into an inner hole to press to be hexagonal and rounding, clearing angles, and enlarging the hole to the designed size; 6; leveling the end face, penetrating the rod again, pressing the small end to be hexagonal and drawing out, chamfering and rounding, leveling the end face, and slight enlarging the inner hole again to the designed size; 7, leveling and reshaping; 8, thermal processing after the infrared measured size is qualified. The bush forging technology has the advantages of being simple and convenient in technology, according to the bush forging technology, qualified product can be directly obtained by forging, the tissue fibers of the product is prevented from being damaged by turning processing, the service life is improved, and meanwhile, the processing amount is reduced, the material is saved, and the cost is lowered.

Description

technical field [0001] The invention relates to a forging process, in particular to a bushing forging process. Background technique [0002] The main steps of the existing bush forging process are as follows: firstly, the rough material is subjected to upsetting and punching to form a hollow cylinder, and then the outer wall is put into a lathe for cutting and forming. Although the product can be formed in this way, there are following deficiencies in such a process: 1. The processing amount is large, resulting in long processing time; 2. When turning on a lathe, the amount of material waste is large, which wastes materials and improves the processing efficiency. 3. During the turning process, the fibrous structure of the forging is destroyed, which affects the quality of the forging, resulting in a shorter service life of the product. Contents of the invention [0003] The object of the present invention is to provide a bush forging process capable of improving the qu...
