Multifunctional sand-blasting grinder

Abstract

The invention discloses a multifunctional sand-blasting grinder which comprises a sand-blasting machine and a machine stand, wherein the sand-blasting machine comprises a sand-blasting gun, a sand storage bucket, a fan and a compressed air filter; the machine stand comprises a bracket capable of making horizontal movement, a workpiece holder and a rack; the bracket is provided with a rotatable disc; the sand-blasting gun is fixedly connected onto the rotating disc and is provided with a sand-blasting hole in the center, and a ring-shaped sand return hole in the outer ring; the sand-blasting hole is communicated with the compressed air filter and the sand storage bucket by a compressed air pipe and a sand outlet pipe respectively; the sand return hole is connected with the fan by a sand return pipe; a grinding material is driven by compressed air to be sprayed outside for grinding a workpiece from the sand-blasting hole, and then is adsorbed and recovered at the sand return hole. The multifunctional sand-blasting grinder is simple and reasonable in structure, easy to operate, simple in implementation and low in cost.

Description

technical field [0001] The invention relates to a multifunctional sandblasting and grinding machine. Background technique [0002] In modern mechanical processing, sandblasting machines are often used to treat the surface of the workpiece, and the accelerated abrasive is used to hit the surface of the workpiece to obtain a certain degree of cleanliness and different roughness, so as to achieve rust removal, deburring, deoxidation layer, and surface atomization treatment. etc. purpose. [0003] The traditional sandblasting machine will produce a lot of dust when grinding the workpiece. The flying dust will not only pollute the environment, affect the health of workers, but also cause waste of abrasives. In order to solve the problem of dust, some sandblasting machines adopt the method of mixing water and co-spraying, using high-pressure water pumps to provide high-pressure water flow mixed with abrasives to spray out, but this method increases high-pressure water pumps and o...

Problems solved by technology

[0003] The traditional sandblasting machine will produce a lot of dust when grinding the workpiece. The flying dust will not only pollute the environment, affect the health of workers, but also cause waste of abrasives.

In order to solve the problem of dust, some sandblasting machines adopt the method of mixing water and co-spraying, using high-pressure water pumps to provide high-pressure water flow and mixed abrasives to spray out, but this method increases equipment such as high-pressure water pumps, increases costs, and the abrasives are difficult to separate and recycle.

Moreover, most of the traditional sandblasting machines are semi-automatically controlled, requiring manual operation of the sandblasting gun, and relying on the experience of the workers to control the grinding effect, resulting in low production efficiency and low product yield.
