Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a rust removal shot blasting machine. Background Art

[0002] Shot blasting machine is a casting equipment, mainly used for sand removal, core removal and cleaning of castings. It uses high-speed projectiles thrown by the shot blaster to impact the surface of the material object to achieve the purpose of cleaning or strengthening the surface. This treatment technology is faster and more effective than other surface treatment technologies. The working principle of the shot blasting machine is to project steel shot or other granular materials onto the metal surface to be treated, and remove impurities on the surface through high-speed impact and friction;

[0003] In the prior art, a Chinese patent with a patent publication number of CN220113079U discloses a steel pipe rust removal shot blasting machine. The shot blasting box of the device can play a good protective role. During the operation of the shot blasting machine, it can effectively avoid environmental pollution and accidental injury to surrounding workers. At the same time, the sand and shot after shot blasting can fall into the inside of the recovery chamber and be recycled again.

[0004] However, when the device is removing rust from the steel pipe, one side is fixed by a positioning shaft, and the other side needs to support the pipe by two rollers. The installation of the two rollers will limit the movement of the sliding frame into the feed box of the shot blasting box, resulting in the pipe at the feed box being unable to be removed from rust. The direction of the pipe needs to be turned around for rust removal, which affects the rust removal efficiency. Therefore, the present application provides a rust removal shot blasting machine to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a rust removal shot blasting machine to solve the problem that the roller at the feed port of the existing rust removal shot blasting machine will limit the sliding frame from moving into the feed box, resulting in the pipes in the feed box being unable to be rusted.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A rust removal shot blasting machine comprises a base plate, a vertical plate is fixedly arranged on the right side of the upper surface of the base plate, a first fixed head is rotatably arranged on the vertical plate through a bearing, a bracket is fixedly arranged between the left side of the upper surface of the base plate and above the vertical plate, a first motor is fixedly arranged above the left side surface of the bracket, a screw rod is installed at the output end of the first motor, a sliding rod is threadedly connected to the screw rod, a fixing ring is fixedly arranged at the bottom of the sliding rod, a plurality of shot blasting heads are installed on the inner surface of the fixing ring, an electric telescopic rod is fixedly arranged at the bottom of the left side surface of the bracket, a sliding plate is fixedly arranged at the output end of the electric telescopic rod, a second motor is fixedly arranged on the left side surface of the sliding plate, and a second fixed head is fixedly arranged at the output end of the second motor.

[0008] Optionally, the axes of the first fixing head, the second fixing head and the fixing ring are on the same straight line.

[0009] Optionally, the first fixing head and the second fixing head are in a frustum shape with a smaller diameter on the proximal side and a larger diameter on the distal side.

[0010] Optionally, the shot blasting heads are evenly distributed on the inner surface of the fixing ring, and 6-12 shot blasting heads are provided.

[0011] Optionally, the horizontal height of the top surface of the sliding rod is equal to the horizontal height of the inner top of the bracket, and the top of the sliding rod is in close contact with the top surface of the bracket.

[0012] Optionally, the fixing ring is in the shape of a hollow annular box, and a plurality of nozzles are penetrated on the inner surface of the fixing ring, a water inlet pipe is penetrated on the side of the fixing ring, a water pump is fixedly installed at the bottom of the water inlet pipe, and a water tank is fixedly installed at the bottom of the water pump.

[0013] Optionally, the water tank is a box structure with an opening at the top, the water pump is fixed to the inner bottom of the water tank, and the water tank is filled with water.

[0014] Optionally, a plurality of the nozzles are provided, and the nozzles and the shot blasting heads are alternately arranged on the inner surface of the fixing ring.

[0015] Optionally, a blocking net is fixedly provided on the upper inner side of the water tank, and the blocking net is arranged in an inclined shape with one side having a higher horizontal height and the other side having a lower horizontal height.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, a first fixing head and a second fixing head are provided. When fixing the pipe that needs to be derusted, the pipe that needs to be derusted is sleeved between the first fixing head and the second fixing head, so that the first fixing head and the second fixing head respectively support the two ends of the pipe that needs to be derusted, thereby ensuring the stability of the pipe when it is fixed. The first fixing head and the second fixing head will not affect the movement of the fixing ring to the two ends of the pipe, thereby ensuring that the fixing ring drives the shot blasting head to move to the two ends of the pipe during rust removal, thereby ensuring that the pipe is completely derusted, thereby increasing work efficiency. The first fixing head and the second fixing head are in the shape of a truncated cone with a small diameter on the near side and a large diameter on the far side, thereby enabling the first fixing head and the second fixing head to cooperate to fix pipes of different diameters, thereby increasing adaptability.

[0018] By providing a nozzle and a water tank, during the rust removal process, the water pump is turned on, the water pump draws the water in the water tank into the fixed ring, and then sprays it out from the nozzle. The sprayed water absorbs the dust generated by the rust removal to achieve the dust removal effect, and the sprayed water falls back into the water tank, which is convenient for the recycling of water.

[0019] By providing a blocking net, the sand shots sprayed from the shot blasting head fall into the water tank and are blocked by the sand shots on the blocking net. Since the blocking net is inclined with one side having a higher horizontal height and the other side having a lower horizontal height, the sand shots on the surface of the blocking net move to the side with a lower horizontal height of the blocking net under the action of gravity, which facilitates the recovery and reuse of the sand shots.
