Problems solved by technology

Because the diameter of the middle hole of the finished product is too small (φ17.4mm), the middle hole cannot be pre-forged at one time when precision forging the blank. Pre-hole, then finish turning the middle hole to size, its production efficiency is low, and the labor intensity of machine tool operators is high
Therefore, the drilling process is the bottleneck of the machining production line, and two drilling machines are needed to meet the needs of the machining production line, and the hands of drilling machine operators are often corroded by cutting fluid or scratched by iron filings. This process also affects the production site and The quality of the surrounding environment, for which the production process must be improved

Embodiment Construction

[0018] A claw pole red trimming and punching composite process, which has the following process steps: a. blanking; b. hot forging, and simultaneously forging the center pre-holes on both ends of the claw pole blank; c. using a red trimming punching compound die The two processes of red trimming and red punching of the claw pole blank are completed at one time; d, shot blasting; e, shaping; f, turning plane; g, finishing turning.

[0019] Such as figure 1 As shown, the above-mentioned red trimming and punching composite formwork includes an upper template 1 and a lower template 2 arranged up and down oppositely, and the two sides of the bottom surface of the lower template 2 are fixedly connected with two lower support seats 91, 92 respectively. The side of the lower template 2 facing the upper template 1 is fixedly connected with a trimming die 3 for placing the formed claw pole hot forging blank 10 and performing red trimming on it and for red punching the claw pole hot forg...

Abstract

The invention relates to a red trimming and punching compound process of a claw pole. The red trimming and punching compound process includes the following steps of a, blanking; b, hot forging, wherein center prebores are forged in two end faces of a claw pole workblank; c, red trimming; d, shot blasting; e, reshaping; f, face cutting; g, fine turning. In the step c, a red trimming punching compound moldbase is adopted to complete the two working procedures of red trimming and red punching of the claw pole workblank at one time. The red trimming and punching compound process of the claw pole can punch a center hole at one time when the red trimming is carried out on the claw pole workblank.

Description

technical field [0001] The invention relates to a composite process of trimming and punching with claw pole red. Background technique [0002] The claw pole is the key part of the automobile generator. It has various varieties and complex shapes, mostly 6 claws and 8 claws. The requirements for dimensional accuracy and internal quality are relatively high, and the production and manufacturing are very difficult. Because the diameter of the middle hole of the finished product is too small (φ17.4mm), the middle hole cannot be pre-forged at one time when precision forging the blank. Pre-hole, and then finish turning the middle hole to size, its production efficiency is low, and the labor intensity of machine tool operators is high. Therefore, the drilling process is the bottleneck of the machining production line, and two drilling machines are needed to meet the needs of the machining production line, and the hands of drilling machine operators are often corroded by cutting fl...
