Abstract

The invention relates to a quenching collet used for the straight section of the end of an automobile leaf spring, comprising a quenching collet, a U-shaped installation hole is vertically arranged on the quenching collet, and a quenching collet is vertically arranged on the bottom of the quenching collet The straight section at the end, the quenching chuck is installed and positioned on the body of the quenching swinging machine by the bolt through the U-shaped mounting hole, and the straight section at the end of the quenching chuck is evenly equipped with multiple full-through oil grooves with arc-shaped cross-sections . The invention solves the problem that the cooling speed of the leaf spring end is slowed down due to the contact surface during quenching and forming, resulting in a lower quenching structure conversion rate. Through the multi-channel all-through oil grooves uniformly arranged under the straight section of the end of the quenching chuck, It can increase the contact area between the quenching medium and the end of the leaf spring, and ensure the cooling rate so as to solve the problem of the transformation rate of the quenching structure.

Description

technical field [0001] The invention relates to a tooling for heat treatment of leaf springs, in particular to a quenching chuck used for the straight section at the end of an automobile leaf spring. Background technique [0002] Heat treatment forming tooling is a necessary equipment for leaf spring forming. The louver clip forming fixture has strong versatility and is widely used. The quenching chuck of the straight section at the end of the traditional automobile leaf spring is as follows: figure 1 , 2 As shown, the quenching chuck 1 is vertically provided with a U-shaped mounting hole 2, and the bottom of the quenching chuck 1 is horizontally and vertically provided with a straight section 3 at the end of the quenching chuck. The quenching chuck 1 is formed by bolts passing through the U-shaped mounting hole. 2. Install and locate on the body of the quenching swing machine. After clamping, the straight section 3 at the end of the quenching chuck is closely attached to...
