Abstract

The invention relates to the field of leaf spring processing equipment and technology, and specifically discloses a leaf spring hot bending forming unit and a bending forming process. The equipment group includes a heating furnace, a bending forming machine and a connecting device. The process includes: S1, to be The bent steel plate is placed on the steerable conveying device and heated by the heating furnace. When heating, the steerable conveying device drives the steel plate to stay in the preheating zone of the furnace body for 10-60s to preheat the steel plate and then continue to convey to the furnace Heating in the body; S2. Transfer the heated steel plate to the bending machine through the connecting device for bending. The beneficial effects of the invention are: the steel plate after bending has consistent performance, and the performance of the leaf spring composed of it is also more stable, and processing multiple steel plates at the same time improves the production efficiency, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of leaf spring processing, in particular to a leaf spring hot-bending forming machine and a hot-bending forming process. Background technique [0002] A spring composed of a single steel plate or a stack of multiple steel plates. The plate spring has friction between the plates and has a large buffering and damping capacity, and is widely used in the suspension of automobiles, tractors and railway vehicles. [0003] During the processing of the leaf spring, the steel plate needs to be heated, bent and quenched. In the technical scheme of the heating furnace in the prior art, only a single leaf spring can be heated, and only the end of the leaf spring can be heated. Heating, the heating efficiency is low, and the function is single; when heating the leaf spring, the leaf spring is not preheated, and it is directly heated, which has a certain impact on the performance of the steel plate, and the heating metho...
