Shot blasting equipment for surface treatment of automobile leaf spring

Abstract

The invention provides shot blasting equipment for surface treatment of an automobile leaf spring and belongs to the field of equipment and processes for surface treatment of spring steel. The shot blasting equipment is characterized by comprising a shot storage device, a weighing and shot conveying device, a shot blasting device and a steel shot recycling device; and an output port of the shot storage device is sequentially connected with the weighing and shot conveying device, the shot blasting device and the steel shot recycling device through conveying pipes, and the steel shot recycling device is connected with an input port of the shot storage device through a stepped conveying belt. The surface shot blasting strength and the covering surface of the spring steel can be accurately controlled, and step-by-step treatment of shot blasting on the surface of a workpiece from coarse to fine can be achieved in an assembly line manner. The second technical purpose that used steel shots can be collected, filtered and sorted, and broken shots and iron residues can be automatically filtered out is achieved through the shot blasting equipment.

Description

technical field [0001] The invention belongs to the field of spring steel surface treatment equipment and technology, and in particular relates to a surface treatment shot blasting equipment for automobile leaf springs. Background technique [0002] Shot blasting includes shot blasting cleaning and shot blasting strengthening. As the name suggests, shot blasting cleaning is to remove impurities such as surface oxide skin to improve the appearance quality. Shot blasting strengthening is to use high-speed moving projectile flow to continuously impact the surface of the strengthened workpiece, forcing the target surface and surface layer The following changes occur during the cyclic deformation process: 1. The microstructure is modified; 2. The non-uniform plastic deformation outer layer introduces residual compressive stress, and the inner surface produces residual tensile stress; 3. The roughness of the outer surface changes. This process can improve the fatigue fracture resi...

AI Technical Summary

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.
