Hot straightening die for first gear and second gear shifting fork

Abstract

The invention discloses a thermal correction mold for a one-two shift fork, which belongs to the field of mold design technology, and includes an upper mold, a lower mold, an upper mold groove, a lower mold groove, and a fixed boss. The base bodies of the upper mold and the lower mold are uniform. It is a cuboid, the upper mold groove is located on the lower surface of the upper mold, the lower mold groove is located on the upper surface of the lower mold, the upper mold groove and the lower mold groove are arranged symmetrically front and rear, and the fixed boss is arranged on the left-right symmetrical line of the upper surface of the lower mold One at the front and one at the front and back, and fixed counterbores are set at the corresponding positions of the upper mold. When the upper mold and the lower mold are closed, the fixed boss and the counterbore are embedded and installed. High, the first and second gear shift fork heat correction mold disclosed by the present invention has good safety, the upper mold and the lower mold are conveniently fixed, the thermal correction accuracy of the parts is high, the bending degree of the upper mold groove and the lower mold groove is large, and the first and second gears The shift fork is placed between the upper mold and the lower mold at high temperature for thermal correction processing, and the forming efficiency is high.

Description

technical field [0001] The invention relates to the technical field of mold design, in particular to a heat correction mold for a one-two shift fork. Background technique [0002] Some auxiliary parts that are often used in vehicles and mechanical equipment have irregular shapes. Shift forks are a common type of such parts. The traditional processing methods for these parts are mostly casting. The processing efficiency of this processing method and The accuracy is very low, and it is easy to cause damage to other important parts in vehicles and mechanical equipment. These parts can also be processed by forging. Due to the unreasonable structural design of the previous forging die, the die strength and precision are low, which affects the transmission parts. Therefore, it is very necessary to design a first and second shift fork thermal correction die with good safety, high hardness of the mold base, high strength, accurate positioning of the upper and lower dies, and high pr...
