Rotating disc type numerical control sand blasting and shot blasting machine for large workpieces

Abstract

The invention belongs to the technical field of surface treatment equipment, and particularly discloses a rotating disc type numerical control sand blasting and shot blasting machine for large workpieces. The rotating disc type numerical control sand blasting and shot blasting machine comprises a rack, a sand blasting bin and a sand collecting bin are sequentially arranged on the rack from top to bottom, an electric trolley with a translation function is connected onto a working panel of the rack, a rotating disc is rotatably connected onto the electric trolley, the rotating disc is located between the sand blasting bin and the sand collecting bin, a sliding seat is connected in the sand blasting bin in an inclined sliding mode, a spray gun is connected to the sliding seat in a lifting mode, a conveying mechanism is arranged in the sand collecting bin, and a lifting mechanism is arranged at the discharging end of the conveying mechanism and connected with the spray gun through a shot blasting device. According to the rotating disc type numerical control sand blasting and shot blasting machine for the large workpieces, the rotating disc is automatically moved into the sand blasting bin through the electric trolley, efficient sand blasting is achieved through cooperation of rotation of the rotating disc and oblique movement of the spray gun, then the sprayed sand is output through the conveying mechanism, the sand is lifted to the shot blasting device through the lifting mechanism to be recycled, and continuous and stable sand blasting is achieved.

Description

technical field [0001] The invention belongs to the technical field of surface treatment equipment, and in particular relates to a turntable-type numerically controlled sandblasting and shot-peening machine for large workpieces. Background technique [0002] The sandblasting machine is a new type of equipment powered by abrasive liquid pumps and compressed air to perform abrasive liquid spraying and finishing on workpieces. It can clean the rough skin, scale, residual salt and burrs of forging and casting blanks, welded parts, heat treatment parts, stamping parts and machined parts. It can be used as pretreatment before coating and plating, and can complete complex shapes. , High-precision, high-gloss parts processing. [0003] The traditional sandblasting equipment usually keeps the workpiece still and the spray gun rotates to blast the workpiece, or the spray gun keeps still and the workpiece rotates to blast the workpiece. For some complex workpieces with irregular shape...

Problems solved by technology

[0003] The traditional sandblasting equipment usually keeps the workpiece still and the spray gun rotates to blast the workpiece, or the spray gun keeps still and the workpiece rotates to blast the workpiece. For some complex workpieces with irregular shapes, especially large workpieces with large volume (such as large molds) , not only the sandblasting effect is poor, but also prone to partial spraying leakage, resulting in low sandblasting accuracy and low yield of workpieces
