Problems solved by technology

This function cannot be realized in existing published technical documents. For example, the patent No. 201080002776.7 discloses a shot blasting device in a patent document titled "Shot Peening Device". Units and Recovery Units
The shot peening device involved in this patent can only store projectiles of one specification, so it can only be shot once. For workpieces that need to be shot many times, there are problems such as changing the shot peening device and multiple clamping. Affect work efficiency

Embodiment Construction

[0036] A mixed shot peening method, combining process and figure 1 described as follows:

[0037] method one

[0038] A variety of projectile spraying process in different time periods: it can be one kind, two or more kinds of projectiles, in the same clamping, the same device can be shot peened in different time periods through different channels and different specifications,

[0039] For example: according to the process requirements, the pipeline 3 connecting the main material bin 1, the auxiliary material bin 2, the shot blaster 8 and the projectile recovery device 7 is equipped with a valve 4, and if the projectiles in the auxiliary material bin 2 are required, the 21 valves are opened. After the corresponding valve 4 passes through the main material bin 1, the shot peening manipulator 6 performs shot peening on the workpiece. After a certain period of shot peening, the corresponding valve 21 is closed, the shot peening manipulator 6 stops peening, and the shot peening m...

Abstract

The invention discloses a mixed shot blasting method which specifically comprises the following steps: respectively placing shots in one or more specifications into 21, 22 to 2i (i is greater than or equal to n) cabins of an auxiliary cabin; sequentially opening one or more of the 21, 22 to 2i (i is greater than or equal to n) cabins of the auxiliary cabin or opening a plurality of corresponding valves at the same time; proportioning the shots according to requirement, and after shots in one or more specifications enter into a main cabin, fully mixing the shots in the main cabin; opening a valve which connects the main cabin and a shot blasting mechanical arm pipeline, wherein a shot blasting mechanical arm blasts shots to a workpiece; after stopping blasting shots, enabling the shot blasting mechanical arm to return to an automatic nozzle-changing cabin of the shot blasting mechanical arm for replacing the nozzle, wherein the rest shots in the main cabin enter into a shot recovery device. The method disclosed by the invention eliminates the risk of micro-cracks generated by same blast shots, so that multiple functions of the device are realized, the work efficiency is improved and the labor intensity is reduced.

Description

technical field [0001] The invention relates to a shot peening method, in particular to a mixed shot peening technology for 304 stainless steel plates and a method capable of realizing multiple shot peening of different specifications and types of projectiles at one time and mixing of various specifications and models of projectiles in one shot peening. Background technique [0002] Shot peening is a traditional material surface strengthening method. Accelerated projectiles are used to hit the surface of the sprayed material to cause large plastic deformation on the surface, thereby generating residual compressive stress on the surface of the target body to improve the fatigue strength and stress resistance of the material. Corrosion ability and surface hardness. [0003] Because shot peening does not require high-tech equipment and is suitable for most metals and parts of various shapes, and has low energy consumption, simple operation and convenient implementation, it has ...
