Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical processing equipment technical field, especially a device for shrapnel shell shot blasting. BACKGROUND

[0002] In the industrial production field, often use shot blasting equipment (shot blasting machine) to the corresponding parts shot blasting (use high speed jet sand shot and iron shot etc., impact the workpiece surface, to improve the part of the mechanical properties and change the surface state). Affected by different factors such as different to be processed equipment and equipment material (for example due to the change of processing parts), different processing technology, etc., the shot blasting equipment adopts different projectile materials when carrying out shot blasting process on different equipment parts, which may be cast iron shot, ceramic shot, sand shot, etc., and the outer diameter of the projectile of different materials is also different.

[0003] The shrapnel shell also needs to use shot blasting program in processing, in the prior art, one of the electric conveying lines continuously sends the shrapnel shell needing shot blasting to the shot blasting work station, a multi-axis robot based on PLC etc. controls the machine hand to clamp and place the shrapnel shell needing shot blasting on the shot blasting table, then the multi-axis robot arm clamps the shot blasting gun (a solenoid valve is connected in series between the shot blasting gun and the shot blasting generator output pipe, and the solenoid valve is controlled by PLC to open during shot blasting), and respectively carries out shot blasting on the outer side and the blind hole of the shrapnel shell (when carrying out shot blasting on the blind hole, the shot blasting gun carries out shot blasting on the inside of the blind hole of the shrapnel shell from bottom to top, and the shot blasting shot falls out of the lower end of the blind hole after shot blasting); then the dust removal equipment (air compressor) controlled by PLC etc. carries out air blowing on the outer surface of the shrapnel shell, and the dust etc. remaining on the surface of the shrapnel shell falls into the collecting bin (the multi-axis robot places the shrapnel shell after shot blasting on another electric conveying line, and conveys the shrapnel shell after shot blasting to the next station) together; then the electric screw conveyor at the lower end of the collecting bin conveys the collected shot and dust etc. to the treatment equipment, the treatment equipment screens the dust mixed in the shot and the shot with unqualified particle size that is too small after collection by the dust collector (the dust and the shot with unqualified particle size that is too small are uniformly treated after collection by the dust collector), and re-outputs them to the material box of the shot blasting generator device; the shot blasting generator device pressurizes the shot stored and recycled in the material box at high speed, and the shot enters the shot blasting gun again to carry out shot blasting on the next shrapnel shell. The above-mentioned shrapnel shell shot blasting complete equipment composed of the electric conveying line, the shot blasting generator device, the multi-axis robot based on PLC control, the dust collector, the treatment equipment, the collecting bin, the electric screw conveyor, the dust collector, the dust removal equipment (compressed air output by the air compressor is used as power source), the shot blasting gun, etc. is collectively referred to as a shrapnel shot blasting system.

[0004] Although the existing grenade shell shot blasting system meets the production needs to some extent, its shortcomings are also obvious due to the structure. Specifically, only one grenade shell can be placed on the shot blasting table for shot blasting processing at a time, the outer side and blind hole of the grenade shell cannot be simultaneously subjected to shot blasting processing, and the blowing operation can be performed only after the shot blasting process of a corresponding grenade shell is completed, so the production efficiency is relatively low.
