Air-suction recycling type two-spray-head sand blasting machine for automobile part

Abstract

The invention relates to an air-suction recycling type two-spray-head sand blasting machine for an automobile part. The air-suction recycling type two-spray-head sand blasting machine comprises a housing, and further comprises a circulating transmission device, wherein a sand blasting cavity and a sand blasting device are arranged in the housing; the sand blasting device comprises a sand supply pipeline and two sand blasting mechanisms; each sand blasting mechanism is separately arranged on the left upper side or the right upper side of a clamp; the circulating transmission device comprises aring-shaped conveyor belt and a circulating drive mechanism for driving the ring-shaped conveyor belt to move in a circulating mode; a charge hole and a discharge hole for allowing the conveyor belt to get in and out are formed in the housing; blast sand recycling boxes are separately arranged on positions, on the charge hole and the discharge hole, of the housing; each blast sand recycling box isseparately equipped with a box body outlet, a box body inlet and a curtain; a blast sand collecting pipeline is arranged on the bottom of each blast sand recycling box; and a negative-pressure mechanism for guiding blast sand to the outside of the corresponding blast sand recycling box is arranged on the corresponding blast sand collecting pipeline. With the adoption of the scheme, the inventionprovides an air-suction recycling type two-spray-head sand blasting machine for the automobile part, and the air-suction recycling type two-spray-head sand blasting machine avoids blast sand waste andenvironmental pollution as a result of taking out products.

Description

technical field [0001] The invention relates to a sandblasting machine, in particular to a sandblasting machine with two spray heads for air suction recovery type automobile parts. Background technique [0002] The sandblasting machine uses the impact and cutting effect of abrasives on the surface of the workpiece to obtain a certain degree of cleanliness and different roughness on the surface of the workpiece, which improves the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece and increasing It improves the adhesion between it and the coating, prolongs the durability of the coating film, is also conducive to the leveling and decoration of the coating, removes impurities, variegated colors and oxide layers on the surface, and at the same time roughens the surface of the medium to eliminate workpieces. Residual stress and increase substrate surface hardness. [0003] The traditional sandblasting machine is only used for s...

Problems solved by technology

[0003] The traditional sandblasting machine is only used for sandblasting tubular components. When sandblasting auto parts with holes, the auto parts can only be manually placed on the processing platform in the sandblasting machine. After the sandblasting is completed Take out, in the process of taking out or observing the processing progress of the product, a part of sandblasting is often carried, which will not only be wasted, but also pollute the air environment near the equipment
