Automatic quenching production line

Abstract

The invention discloses an automatic quenching production line, and belongs to the field of plate spring shaping and heat treatment equipment. The automatic quenching production line is characterized by comprising a stepping type quenching furnace, a plate spring bending shaping device and a quenching pond. The stepping type quenching furnace is linked with the plate spring bending shaping device through a mechanical hand, and the plate spring bending shaping device is linked with the quenching pond through an oil inlet mechanism. The plate spring bending shaping device comprises a shaping machine frame, a feeding mechanism, a length alignment mechanism, a width alignment mechanism, a shaping device and a material supporting lifting mechanism; the feeding mechanism, the length alignment mechanism, the width alignment mechanism, the shaping device and the material supporting lifting mechanism are installed on the shaping machine frame. Heating, shaping and quenching operation of a plate spring can be automatically implemented, various working procedures are automatically and continuously executed, linage is compact, and the product production efficiency and the output quality are greatly improved.

Description

technical field [0001] The invention belongs to the field of shaping and heat treatment equipment for leaf springs, and in particular relates to an automatic quenching production line. Background technique [0002] Leaf Spring Leaf Spring is the most widely used elastic element in automobile suspension. It is composed of several alloy spring sheets with equal width but unequal length (the thickness can be equal or not). An elastic beam of approximately equal strength. When the leaf spring is installed in the automobile suspension and the vertical load it bears is positive, each spring leaf is deformed by force and tends to arch upward. At this time, the axle and frame are close to each other. When the axle and frame move away from each other, the positive vertical load and deformation of the leaf spring gradually decreases, and sometimes even reverses. [0003] The flat rectangular steel plate is curved, and the chassis is made of several stacked springs. One end is insta...

Problems solved by technology

In the implementation process of the above steps in the prior art, due to the unreasonable structure of the equipment, the connection between the various processes relies on manual operation

In addition, there are many problems in the equipment involved in each process

For example, after the reed is heated to the specified temperature, the furnace must be opened to pick up the piece, which is not only time-consuming and laborious, but also prone to burn accidents during the pick-up process. Opening the furnace to pick up the piece will inevitably cause the temperature curve in the heating furnace to change, causing a large amount of heat in the furnace to be lost unnecessarily. , wasting energy

And, the traditional leaf spring shaping technology adopts hard contact bending, which is not conducive to the uniform bending of the leaf spring. In addition, the hard contact will also cause trauma to the surface of the leaf spring, affecting the quality of the formed workpiece
