Description

Technical Field

[0001] The invention relates to the technical field of stainless steel production, in particular to a continuous stress relief device based on stainless steel production. Background Art

[0002] During the forging, cutting, casting, welding and other processing, metal components will produce uneven plastic deformation due to uneven stress or heat, and residual stress will exist after processing. Residual stress is an important cause of cracking or deformation of metal components, and seriously affects the fatigue strength and dimensional accuracy stability of metal components.

[0003] At present, the method used to eliminate the inherent stress of steel is to anneal the steel material, and then the production personnel manually knock around the mold with tools such as rubber hammers to remove the residual stress inside the steel after annealing. However, this manual knocking method of removing residual stress is inefficient and has high labor costs, which is not conducive to improving work efficiency. In addition, shot peening is to hit the surface of steel by spraying metal particles at high speed, which can also remove stress. However, the existing shot peening equipment requires manual movement of the shot peening mechanism, which is inconvenient. Since manual movement cannot ensure uniform shot peening, the surface shot peening effect of the steel plate is different. Secondly, the sprayed steel shots fly everywhere, and the steel shots cannot be collected and sorted. The oxide scale, rust and dust impurities on the surface of the steel plate are also scattered everywhere and mixed with the steel balls, and personnel are required to classify and clean them.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a continuous stress relief equipment based on stainless steel production is proposed. Summary of the invention

[0007] Furthermore, a bucket elevator is arranged on the side of the bottom plate, and a feed trough at the lower end of the bucket elevator corresponds to a discharge pipe at the end of the guide bin.

[0008] Furthermore, brackets are fixed at four corners of the bottom plate, and the top ends of the brackets are bolted to fixed limiting angle irons.

[0009] Furthermore, a fixing frame is bolted to the inner side of the limiting angle iron, and a stainless steel belt is conveyed between the fixing frames arranged opposite to each other.

[0010] Furthermore, a stepper assembly is arranged inside the bracket, and the stepper assembly includes a driving pulley, a bevel gear and a bevel gear motor. The outer side of the driving pulley is coaxially connected with a bevel gear, and the bevel gear is meshed with the bottom bevel gear motor for transmission.

[0011] Furthermore, the stepper assembly also includes a synchronous belt and a driven pulley. The driving pulley is covered with a synchronous belt, and the synchronous belt is rotated with the driven pulley at one end away from the driving pulley, and the driven pulley and the driving pulley are respectively rotatably installed on two brackets on the same side.

[0012] Furthermore, the stepper assembly also includes a crank and a movable frame, the driven pulley and the inner side of the driving pulley are connected to the crank for transmission, and the crank is eccentrically connected to the movable frame at one end away from the rotation center of the driven pulley and the driving pulley, and the movable frame is eccentrically arranged in the gap between the opposite surfaces of the fixed frames on both sides.

[0015] Furthermore, the shot blasting assembly also includes a nozzle and an impeller body. The nozzle is opened on the side of the bottom of the cover shell, and the cover shell is rotatably installed on the impeller body.

[0016] The present invention provides a continuous stress relief device based on stainless steel production, which has the following beneficial effects:

[0017] 1. During the use of the present invention, the driven pulleys and the inner sides of the driving pulleys on the two brackets on the same side drive the movable frame to swing in the gap between the opposite surfaces of the fixed frame through the crank.
