A surface treatment production line for spring steel

Abstract

The invention provides a spring steel surface treatment production line and belongs to the field of spring steel surface treatment equipment and processes. The spring steel surface treatment production line comprises a heat treatment apparatus, a shot-blasting apparatus and an electrophoresis apparatus; the spring steel surface treatment production line is characterized in that the shot-blasting apparatus comprises a shot storage device, a weighing shot-conveying device, a shot-blasting device and a steel shot recovering device, wherein an output opening of the shot storage device is orderly connected with the weighing shot-conveying device, the shot-blasting device and the steel shot recovering device through a conveying pipe; the steel shot recovering device is connected with an input opening of the shot storage device through a stepped conveyor belt. The spring steel surface treatment production line is capable of accurately controlling the surface shot-blasting strength and the covering surface of the spring steel and also capable of realizing stepping processing on a surface of a workpiece from coarse to fine by means of shot blasting in a pipeline manner. The second technical problem solved by the spring steel surface treatment production line is that the used steel shots can be collected, filtered and sorted and broken shots and iron residue can be automatically filtered out.

Description

technical field [0001] The invention belongs to the field of spring steel surface treatment equipment and technology, in particular to a spring steel surface treatment production line. Background technique [0002] After the initial forming of the spring steel sheet, it needs to be processed by a series of surface treatment equipment before it can be finally formed into a finished product. The surface treatment equipment includes heat treatment, shot blasting, high temperature compression, cooling and setting, electrophoresis and other process steps. Among them, the shot blasting operation is one of the more important processes, which directly affects the quality of the finished product of the spring steel sheet. The shot blasting process includes shot blasting cleaning and shot blasting strengthening. As the name suggests, shot blasting cleaning is to remove impurities such as surface scale to improve the appearance quality. The surface and surface layer of the material un...

Problems solved by technology

[0003] However, the traditional shot blasting process cannot accurately control the speed, angle, and distance between the shot head and the steel plate surface for precise control. In addition, for the high-speed impact and crushing problems that occur during normal use of shot blasting, automatic sorting and filtering cannot be achieved. , which seriously affects the speed and quality of the continuous cycle of shot blasting

[0004] In addition, the general shot blasting process adopts extensive hitting and collision operations, and the degree of refinement is low, and it is impossible to achieve polishing treatment on the surface of the workpiece. Instead, it relies on an additional polishing machine for secondary processing, which seriously reduces production efficiency.
