Pneumatic numerical control shot blasting machine

Abstract

The invention belongs to the technical field of material surface treatment, and particularly relates to a pneumatic numerical control shot blasting machine. Comprising a box body, an impeller head, a lifting hook assembly, a feeding box, a waste treatment box, a screening box and a steel shot recovery device, the bottom wall of the box body is of a structure high in front and low in rear, the screening box is arranged on the rear side of the box body and fixedly connected with the rear wall of the box body, and a first discharging opening is formed in the part, fixedly connected with the box body, of the screening box; a wedge-shaped baffle is arranged in the screening box and located on the lower side of the first discharging port and fixedly connected with the front wall of the screening box, the bottom wall of the screening box is of a structure high in front and low in rear, a motor is arranged at the bottom of the screening box, a disc-shaped electromagnet is fixedly connected to the top of a rotating shaft of the motor, and the upper surface of the electromagnet is of an inverted-cone-shaped structure. According to the steel shot screening and recycling device, automatic screening and recycling of steel shots can be achieved, and compared with the prior art, the screening precision is higher, the maintenance frequency is effectively reduced, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of material surface treatment, and in particular relates to a pneumatic numerical control shot blasting machine. Background technique [0002] Shot blasting equipment is firstly used to remove sand and scale on the surface of cast steel and iron castings in the foundry industry. [0003] Almost all steel castings, gray castings, malleable steel parts, ductile iron parts, etc. must be shot blasted. This is not only to remove scale and sticky sand on the surface of the casting, but also an indispensable preparation process before the quality inspection of the casting. For example, the casing of a large gas turbine must be subjected to strict shot blasting before non-destructive testing to ensure the accuracy of the testing results. reliability. In the production of general castings, shot peening cleaning is an indispensable process to find surface defects of castings such as subcutaneous pores, slag pores, s...

Problems solved by technology

[0005] Nowadays, most of the common steel shot recovery and screening devices adopt the principle of mesh screen to filter out the mixed impurities through a certain number of vibrating mesh screens to filter out the steel shots that have become smaller and fragmented, as well as metal debris, rust residue, and dust. , to obtain steel shots that can continue to be recycled, but in this way, due to the different sizes of the steel shots, some steel shots will be stuck on the mesh of the vibrating screen, and the filtering effect of the screen will decrease significantly over time, which is unqualified The steel shot will seriously affect the effect of shot blasting
