[0002] Seamless steel pipe is a pipe with a hollow cross-section, which is widely used to transport fluids such as oil, natural gas, coal gas, water and some fixed materials. Compared with solid steel, when seamless steel pipe has the same bending and torsional strength, the metal material is first smelted into an appropriate chemical composition and molten state, and then processed into a seamless steel pipe with the required diameter and wall thickness through processing techniques such as calendering. After calendering, the surface of the steel pipe needs to be sandblasted with a sandblasting machine to remove impurities such as oxide scale, rust, oil stains, etc. on the surface of the steel pipe, making the surface cleaner and smoother.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A sandblasting machine for seamless steel pipes of metal smelting rolled products is provided with a clamping component group and a side shifting component group. At present, an automatic sandblasting machine is often used to sandblast seamless steel pipes. During operation, the steel pipes are manually placed into the sandblasting machine cabin one by one, and then the sandblasting machine cabin door is closed, and the sandblasting machine is started to sandblast the steel pipes. This operation method is relatively cumbersome. In actual processing, the efficiency of taking and placing the steel pipes from the sandblasting machine is low, which reduces the overall sandblasting work efficiency. When the seamless steel tube body needs to be placed in the sandblasting machine body, first move the movable table in the side shift component group in the Y-axis direction through the slide slot, and move the movable table to the end position of the bottom guide frame away from the limit plate, then put four seamless steel tube bodies on the movable table, open the seamless steel tube bodies, and then move the movable table so that its side contacts the limit plate. The operator holds the adjustment handle with both hands to move the two adjustment handles toward each other, and the spring part accumulates force and contracts. At this time, the movable clamp rod will be close to the fixed clamp rod, so that the seamless steel tube body can be placed on the sandblasting machine body. The seamless steel tube body is clamped, and the non-slip rubber pads on the mobile clamp rod and the fixed clamp rod will contact it. After clamping, push the adjusting handle to move in the direction of the X-axis so that the seamless steel tube body can enter the main body of the sandblasting machine. After the seamless steel tube body reaches the sandblasting position, release the adjusting handle, the spring part releases the stored force, and the mobile clamp rod will return to its position without contacting the seamless steel tube body, thereby releasing the clamping of the seamless steel tube body. Then, the adjusting handle can be pulled to move the mobile seat to a position away from the main body of the sandblasting machine, and then the mobile table can be moved to the position of the bottom guide frame away from the end of the limit plate. At this time, the seamless steel tube body can be closed, and the machine can be turned on to allow the main body of the sandblasting machine to grind the seamless steel tube body inside it. Compared with the current method of placing the seamless steel tube body, this operation can calibrate the position between the seamless steel tube bodies on the mobile table in advance when placing it. At this time, the position of the seamless steel tube body is adjusted. Since there is no shielding of the main body of the sandblasting machine outside, it is more convenient to adjust, which can improve the efficiency of placing the seamless steel tube body, thereby improving the efficiency of the overall sandblasting work;

[0014] 2. The sandblasting machine for seamless steel pipes of metal smelting rolled products is provided with a clamping component group and a side shifting component group. In the correspondingly designed clamping component group and side shifting component group, when it is necessary to take out the seamless steel pipe body after the internal sandblasting is completed, the movable clamping rod and the fixed clamping rod are controlled to clamp the seamless steel pipe body, and the movement of the movable seat is controlled to allow the seamless steel pipe body to be taken out from the inside of the sandblasting machine body. After taking it out, since there is no obstruction from the main structure of the sandblasting machine, the seamless steel pipe body can be taken more conveniently. When facing a heavier seamless steel pipe body, the clamping component group and the side shifting component group can take out the seamless steel pipe body, which is convenient for personnel to carry the seamless steel pipe body and facilitate subsequent operations.

[0023] There are two groups of clamping assemblies 22, and the two groups of clamping assemblies 22 are distributed vertically in upper and lower positions. The movable clamping rod 221 is in sliding contact with the sleeve 222 through a slide groove, the fixed clamping rod 223 is connected to the sleeve 222, and the fixed clamping rod 223 and the movable clamping rod 221 are provided with protective banana pads at positions corresponding to the seamless steel pipe body 13.

[0024] A set of clamping components 22 is provided with two movable clamping rods 221 and a fixed clamping rod 223 , and the two movable clamping rods 221 and the fixed clamping rod 223 are symmetrically distributed on both sides of the sleeve body 222 .

[0025] The adjusting handle 21 is connected to the movable clamping rod 221, the two ends of the spring member 23 are connected between the two movable clamping rods 221, the sleeves 222 in the two sets of clamping assemblies 22 are connected through a bracket, the movable seat 24 is connected to a sleeve 222 at the bottom, and the movable seat 24 is in sliding contact with the upper movable frame 25 through a slide groove.

[0029] Working principle: Currently, automatic sandblasting machines are often used to sandblast seamless steel pipes. During operation, the steel pipes are manually placed into the sandblasting machine cabin one by one, and then the sandblasting machine cabin door is closed and the sandblasting machine is started to sandblast the steel pipes. This operation method is relatively cumbersome. In actual processing, the efficiency of taking and placing the steel pipes from the sandblasting machine is low, which reduces the overall sandblasting work efficiency. In the corresponding designed clamping component group 02 and side shift component group 03, when the seamless steel pipe body 13 needs to be placed in the sandblasting machine body 11, the moving table 31 in the side shift component group 03 is first moved. By moving the slide in the Y-axis direction, the movable table 31 is moved to the end position of the bottom guide frame 32 away from the limit plate 33, and then four seamless steel tube bodies 13 are placed on the movable table 31, the seamless steel tube body 13 is opened, and then the movable table 31 is moved to make its side contact with the limit plate 33.
