Abstract

PURPOSE:To manufacture a socket tie rod free from futile thickness, by preliminarily forming a material having small draft as a whole by hammer die forging and press forming after putting a punch to the inside. CONSTITUTION:A material having draft of 7-10 deg. as a whole is preliminarily formed by hammer die forging. Then, this material is put in a press die 2, and press formed inserting a punch 4 to the inside through a plate 3. By this press forming, the draft of the socket tie rod 1 becomes smaller as a whole, and the dimension of outer periphery of the tie rod 1 becomes close to the finished dimension of the machine. After press forming, the punch 4 is pulled out form the tie rod 1. The pressure of the plate 3 facilitates pulling out.

Description

【発明の詳細な説明】 本発明は限在自動車の足まわり等に広く使われているソ

外側について、１鎗減少を目ざしている自動軍隊 にとって大きな開蓋であった。Socket tie rod molding is done by T-smithing and hammer die forging, so as shown in Figure 1, the socket tie rod is made from the molding surface so that it is in the middle, and from the molding surface to the top and bottom. There are draft angles on the outside and inside. Since the tie rod is finally machined into the shape shown by the two-dot dashed line, there is a large amount of finishing allowance in the machining process, a large number of man-hours, and there is a lot of waste in terms of the life of the cutter. . In addition, there was more meat than necessary on the outside, which was a big opening for the automatic army, which was aiming to reduce its size by one spear.

There is a draft angle of 7 to 10 degrees from that point toward the bottom. Put this material into a punsu mold,
A punch 4 is inserted inside and press molding is performed. This book/
By forming the socket tie rod 1 as a whole, the drawing slope is further reduced, and the outer circumferential dimension of the tie rod 1 approaches the machine finished dimension. Since the punch 4 is inserted and press-formed, the inner dimensions of the tie rod 1 can be made close to the finished dimensions.
