Novel method for producing plate springs

Abstract

The invention discloses a novel method for producing plate springs. The method comprises the steps that the plate springs are stacked together to be preheated according to a certain sequence, and the plate springs are pre-formed; quenching dies are fixed on a quenching machine in advance, the plate springs are sent into the plate spring forming quenching dies after pre-forming, and quenching is performed at the same time; during quenching, a turbine is arranged at the bottoms of the plate spring forming quenching dies, and cooling oil is stirred strongly to guarantee that all portions of the plate springs are evenly cooled and the consistency of metallographic structures in the plate springs is good; and the plate springs after quenching forming are sent back to a tempering furnace through a conveying mesh belt, and tempered reeds can be assembled directly after tempering. According to the novel method for producing the plate springs, the method is simple, the quality and the performance of products are guaranteed, the production cost is lowered, and energy consumption is reduced; the quenching dies used in the quenching process of the plate springs are standardized and systematized, and all the quenching dies are only needed to be produced at a time, so that the method design is simplified, and costs of the quenching dies are reduced.

Description

technical field [0001] The invention relates to the production technical field of leaf springs, in particular to a novel production method for manufacturing leaf springs. Background technique [0002] In the production process of the leaf spring, in order to ensure the various technical requirements of the leaf spring, hard mold processing is used. Generally, during the quenching process of the leaf spring, a quenching machine can only produce one piece of leaf spring per minute, so the output is relatively large. Low, and a production line requires more employees, so it consumes a lot of labor. With the development of my country's economy, labor costs have increased greatly, so it is necessary to improve the method, equipment, and operation methods of leaf springs, and the production efficiency is extremely high. Improve, to reduce production costs, improve production efficiency. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention ...
