A forming and processing system for automobile leaf spring components

Abstract

The invention provides an automobile leaf spring assembly forming and machining system. The automobile leaf spring assembly forming and machining system comprises an upper mold unit, a lower mold unitand an actuator. The actuator is arranged on the upper part of the lower mold unit, the upper mold unit is installed on the lower mold unit, and the actuator is located directly below the upper moldunit. The problems that poor lug hole roundness, large fluctuation in the center distance between two lug holes, complicated hydraulic eye equipment, large investment and other shortcomings exist in an existing leaf spring lug rolling machining technology scheme, the existing leaf spring lug rolling machining technology scheme is low in production efficiency, high in labor intensity and unstable in quality and is generally used in small machining plants, the labor intensity of workers is increased, because no reshaping process exists, the lug holes rolled out have different degrees of bell mouths, and the perpendicularity of the lug holes and reeds does not meet the requirements.

Description

technical field [0001] The invention relates to the technical field of forming automobile leaf spring components, in particular to a forming and processing system for automobile leaf spring components. Background technique [0002] Leaf spring: It is composed of multiple steel plates with unequal lengths and unequal curvatures. After installation, the two ends naturally bend upwards. When the impact force from the road to the wheels comes, the steel plate will deform, which will play the role of cushioning and vibration reduction, and also play the role of guiding and transmitting force when arranged longitudinally. Most of the non-independent suspensions use leaf springs as elastic elements, which can save guide devices and shock absorbers, and have a simple structure. Leaf spring is the most widely used elastic element in automobile suspension. [0003] There are two existing leaf spring rolling lug processing schemes: the first hydraulic rolling lug: material heating, ...

AI Technical Summary

Problems solved by technology

[0003] There are two existing leaf spring rolling lug processing schemes: the first hydraulic rolling lug: material heating, R die-cutting head, center hole positioning, hydraulic cylinder rotation to roll the lug, this processing method is currently used more commonly , there are deficiencies such as poor roundness of the ear holes, large fluctuations in the center distance between the two ear holes, complex hydraulic ear rolling equipment, and large investment; the second type of artificial ear rolling: cutting the head with a heated punching machine, half-wrapping the ear, and taking the ear hole as the center, Pneumatically or manually rotate the ear to form the ear hole. This method of forming the ear hole is simple, the production efficiency is low, the labor intensity is high, and the quality is unstable. It is generally used in small processing plants and the labor intensity of the workers is increased. In the shaping process, the rolled out ear holes have different degrees of bell mouth, and the perpendicularity between the ear holes and the reed does not meet the requirements
