Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a polishing machine for producing cold-drawn precision seamless steel pipes. Background Art

[0002] The steel pipe polishing machine is used to polish the surface of steel pipes. The steel pipe polishing machine is mainly composed of a drive motor, a polishing wheel, a displacement wheel, etc. Cold-drawn precision seamless steel pipes may have some surface defects during the manufacturing, processing or transportation process, such as oxide scale, burrs, stains, etc. The steel pipe polishing machine can remove the defects on the surface of the steel pipe, making the surface of the steel pipe cleaner and smoother, and prolonging the service life of the steel pipe;

[0003] The cold-drawn precision seamless steel pipe is a steel pipe made by cold-drawing a hot-rolled or cold-rolled steel billet. The cold-drawn precision seamless steel pipe is placed between the driving main roller and the auxiliary wheel seat, and the adjusting screw of the auxiliary wheel seat is rotated to confine the seamless steel pipe between the driving main roller and the auxiliary wheel seat. At this time, the motor driving the main roller is started to drive the main roller and the auxiliary wheel seat to transmit the seamless steel pipe. At this time, the driving motor is started to drive the output shaft of the driving motor to drive the polishing wheel to polish the seamless steel pipe. When the polishing machine is finished, the cold-drawn precision seamless steel pipe gradually moves out from between the driving main roller and the auxiliary wheel seat. The staff generally needs to hold the seamless steel pipe by hand to prevent the seamless steel pipe from falling directly from the table of the polishing machine. However, since the seamless steel pipe is still rotating when it gradually moves out from between the driving main roller and the auxiliary wheel seat, the staff's hands are easily injured, which makes it dangerous for the staff to hold the seamless steel pipe by hand. Therefore, we proposed a polishing machine for the production of cold-drawn precision seamless steel pipes. Utility Model Content

[0004] The purpose of the utility model is to provide a polishing machine for the production of cold-drawn precision seamless steel pipes, so as to solve the problem proposed in the above-mentioned background technology that when the cold-drawn precision seamless steel pipe is gradually moved out from between the driving main roller and the auxiliary wheel seat, the staff generally need to hold the seamless steel pipe by hand, which makes the staff's hands easily injured, making it particularly dangerous for the staff to hold the seamless steel pipe by hand.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a polishing machine for the production of cold-drawn precision seamless steel pipes, comprising a polishing machine body and a driving main roller, the upper side of the polishing machine body is sequentially installed with a driving main roller, an auxiliary wheel seat and a driving motor, and the output shaft of the driving motor is installed with a polishing wheel, a bracket is provided on one side of the polishing machine body, and a plug rod is fixed at one end of the bracket, a slot is provided on the side of the polishing machine body close to the plug rod, and the plug rod is connected to the slot, the bracket is connected to the polishing machine body by a limiting bolt, the upper side of the bracket is connected with a fixing ring, and a sliding rod is slidably penetrated inside the fixing ring.

[0006] Preferably, the slide rod is sleeved with the limit spring, and a connecting plate is fixed to one end of the slide rod.

[0007] Preferably, two ends of the limit spring are respectively fixed to the fixing ring and the connecting plate, and a groove is provided on the inner side of the connecting plate.

[0008] Preferably, the slot is engaged with the ball bearing, and a connecting block is fixed on one side of the connecting plate.

[0009] Preferably, a collecting box is provided below the polishing wheel, and a connecting rod passes through the interior of the collecting box.

[0010] Preferably, the connecting rod is movably connected to the collecting box via a bearing, and a limiting block is fixed at one end of the connecting rod.

[0011] Preferably, a limiting groove is provided on one side of the auxiliary wheel seat bottom plate close to the limiting block, and the limiting block is connected to the limiting groove.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when the seamless steel pipe is completely separated from the driving main roller and the auxiliary wheel seat, the seamless steel pipe is restricted between the connecting plates, so that the polishing machine body can connect the seamless steel pipe by itself, so that the staff does not need to manually support the seamless steel pipe for connecting the material, which makes the staff's hands less likely to be injured. The collection box is restricted together with the auxiliary wheel seat. When the polishing wheel polishes the seamless steel pipe, the collection box can collect the waste chips polished by the polishing wheel, so that the polishing machine body is easy to collect and clean the waste chips polished.

[0013] 1. The cold-drawn precision seamless steel pipe production polishing machine is a steel pipe made by cold-drawing hot-rolled or cold-rolled steel billets. Before the main body of the polishing machine is operated, the bracket is fixed to the main body of the polishing machine with a limit bolt. When the main body of the polishing machine is polishing, the cold-drawn precision seamless steel pipe gradually moves out from between the driving main roller and the auxiliary wheel seat, and one end of the seamless steel pipe is squeezed with the connecting plate. When the seamless steel pipe gradually moves between each connecting plate, the connecting plate drives the ball to squeeze the seamless steel pipe under the action of the limit spring. When the seamless steel pipe is completely separated from between the driving main roller and the auxiliary wheel seat, the seamless steel pipe is restricted between each connecting plate, so that the main body of the polishing machine can connect the seamless steel pipe by itself, so that the staff does not need to manually support the seamless steel pipe for connecting, so that the hands of the staff are not easily injured;

[0014] 2. The polishing machine for the production of cold-drawn precision seamless steel pipes, before the polishing wheel grinds the cold-drawn precision seamless steel pipe, places the collection box under the polishing wheel, docks the limit block with the limit groove, rotates the connecting rod, and drives the limit block to rotate, so that the collection box is restricted to one side of the bottom plate of the auxiliary wheel seat. When the staff adjusts the position of the auxiliary wheel seat, the collection box can move with the auxiliary wheel seat. When the polishing wheel polishes the seamless steel pipe, the collection box can collect the waste chips polished by the polishing wheel, so that the main body of the polishing machine is easy to collect and clean the waste chips polished.

[0024] In specific implementation, according to Figure 1-Figure 5 , the cold-drawn precision seamless steel pipe is a steel pipe made by cold-drawing a hot-rolled or cold-rolled steel billet. Before the polishing machine body 1 is operated, the plug rod 201 is first docked with the slot 202. The cross-sectional size of the plug rod 201 matches the cross-sectional size of the slot 202, so that the plug rod 201 is not easy to shake inside the slot 202, which is convenient for the staff to use the limit bolt 203 to fix the bracket 2 and the polishing machine body 1, and then place the cold-drawn precision seamless steel pipe between the driving main roller 101 and the auxiliary wheel seat 102, rotate the adjusting screw of the auxiliary wheel seat 102, so that the seamless steel pipe is restricted between the driving main roller 101 and the auxiliary wheel seat 102, and then start the motor of the driving main roller 101, so that the driving main roller 101 and the auxiliary wheel seat 102 transmit the seamless steel pipe, and then start the driving motor 103, so that the output shaft of the driving motor 103 drives the polishing wheel 104 to polish the seamless steel pipe;

When the staff adjusts the position of the auxiliary wheel seat 102, the collecting box 3 can move with the auxiliary wheel seat 102.
