Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe processing, and particularly relates to a stainless steel pipe polishing device. Background Technique

[0002] A stainless steel pipe is a hollow long round steel, which is mainly widely used in industrial conveying pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments, etc., and mechanical structure components, etc. During the use of the stainless steel pipe, polishing processing of the stainless steel pipe is required.

[0003] When the stainless steel pipe is polished, the inner wall and the outer wall of the stainless steel pipe need to be polished and ground respectively. When grinding the inner wall, the fixture is often fixed on the outer wall. When grinding the outer wall, the fixture is often fixed on the inner wall. Therefore, the polishing of the stainless steel pipe is often divided into two steps, which makes the processing process very cumbersome.

[0004] At the same time, during the polishing and grinding process of the stainless steel pipe, the waste chips generated by polishing need to be disposed of in time to avoid the waste chips polluting the grinding materials and damaging the surface of the nearly completed stainless steel pipe.

[0032] Refer to the drawings. The stainless steel pipe polishing device described in this embodiment includes a base 1, and a feeding mechanism 2 and a polishing mechanism 3 are provided on the base.

[0033] The feeding mechanism 2 includes a mounting frame 21, a support member 22, a first linear module 23, a first support wheel set 24 and a first dust hood 25; the mounting frame 21 is fixed on the base 1, the first linear module 23 is mounted on the top of the mounting frame 21, and the top of the support member 22 is installed on the first linear module 23 through a slider and can move along the first linear module 23.

[0034] The lower part of the support member 22 is of an annular structure, including an outermost fixed ring 221, an intermediate bearing sleeve 222 and an inner rotating ring 223. The rotating ring 223 can rotate relative to the fixed ring 221 through the bearing sleeve 222; the first dust hood 25 is of a horn-shaped structure, one end is installed on the fixed ring 221 of the support member 22, and the other end is connected to a dust removal fan 27 through a telescopic pipe 26.

[0035] A motor mounting frame is provided inside the first dust hood 25, and a rotating motor 28 is installed inside the first dust hood 25. The rotating motor 28 drives the rotating ring 223 to rotate relative to the fixed ring 221. When the stainless steel pipe 4 is placed inside the rotating ring 223, the rotating motor 28 can drive the stainless steel pipe 4 to rotate through the rotating ring 223, which is convenient for polishing.

[0036] A first support wheel set 24 is installed on the base 1. The first support wheel set 24 consists of a pair of support wheels, which are rotatably installed on the base 1. The outer edges of the two support wheels are tangent to the outer wall of the stainless steel pipe 4, and can support the stainless steel pipe to keep the stainless steel pipe 4 in a horizontal state. At the same time, the outer wall of the support wheel is a smooth structure, reducing the friction with the surface of the stainless steel pipe and facilitating the support member 22 to push the stainless steel pipe 4 to move.

[0037] The polishing mechanism 3 includes an outer polishing assembly 31, an inner polishing assembly 32, a pipe-pushing assembly 33 and a second dust hood 34. The outer polishing assembly 31 includes an outer polishing grinding wheel set 311 and an outer polishing motor 312.

[0038] The inner polishing assembly 32 includes an inner polishing grinding wheel 321, a long rod 322 and an inner polishing motor 323. The inner polishing grinding wheel 321 is installed on the inner polishing motor 323 through the long rod 322. The length of the long rod 322 is greater than the length of the stainless steel pipe 4, so that the stainless steel pipe can move from the outside of the inner polishing grinding wheel to complete the polishing work on the inner wall.

[0039] The pipe-pushing assembly 33 consists of a pair of vertically placed pipe-pushing columns 331 and a pipe-pushing motor 332 for driving the pipe-pushing columns to rotate. The pipe-pushing columns 331 are in a cylindrical structure with a reduced outer diameter in the middle, and the two pipe-pushing columns 331 are located on both sides of the long rod 322. The pipe-pushing columns 331 can be in rolling connection with both sides of the stainless steel pipe 4 translated into the polishing area, further supporting the stainless steel pipe 4. The pipe-pushing motor 332 drives the pipe-pushing columns 331 to rotate, which can drive the stainless steel pipe 4 to enter and exit on the support member 22, dock with the support member 22 and convey the stainless steel pipe.

[0040] The outside of the polishing mechanism 3 is covered with a second dust hood 34. The second dust hood 34 completely covers the overall polishing mechanism. The top of the second dust hood 34 is connected to a dust removal fan, which can adsorb the dust generated by the polishing of the outer wall of the stainless steel pipe. The second dust hood 34 is made of transparent acrylic material, which is convenient for users to observe the internal polishing situation through the second dust hood.

[0041] During use:

[0042] 1) The support member 22 is in the initial position. The end of the stainless steel pipe 4 to be polished is placed into the rotating ring 223 of the support member 22, and the other end of the stainless steel pipe 4 is supported by the first support wheel set 24, so that the stainless steel pipe 4 is kept in a horizontal state.

[0043] 2) The first linear module 23 drives the support member 22 to move towards the polishing mechanism 3. The support member 22 pushes the end of the stainless steel pipe 4, so that the other end of the stainless steel pipe 4 enters the polishing area.

[0044] 3) The outer wall of the stainless steel pipe 4 is in contact with the outer polishing grinding wheel set 311. The outer polishing grinding wheel set 311 rotates driven by the outer polishing motor 312 to polish the outer wall of the stainless steel pipe 4. At the same time, the inner polishing grinding wheel 321 extends into the stainless steel pipe 4 and rotates driven by the inner polishing motor 323 to polish the inner wall of the stainless steel pipe 4.

[0045] 4) Start the dust removal fan connected to the first dust hood 25 and the second dust hood 34. The first dust hood 25 is in a negative pressure state to adsorb the powder generated by the polishing of the inner wall of the stainless steel pipe 4, and the second dust hood 34 is used to adsorb the powder generated by the polishing of the outer wall of the stainless steel pipe 4.

[0046] 5) The support member 22 pushes the stainless steel pipe 4 into the polishing area, and the pipe-pushing column 331 is in contact with the stainless steel pipe 4. The pipe-pushing column 331 can support the stainless steel pipe and drive the stainless steel pipe 4 to move forward continuously, so that the end of the stainless steel pipe can leave the support member, which is convenient for the outer polishing grinding wheel set 311 to polish and grind the end of the stainless steel pipe. At the same time, the stainless steel pipe can be supported by the second support wheel set 25 on the polishing mechanism.

[0047] 6) After the polishing is completed, the inner polishing grinding wheel 321 and the outer polishing grinding wheel set 311 stop working, and the pipe-pushing column 331 rotates in the reverse direction to send the stainless steel pipe 4 back to the feeding mechanism and unload it from the feeding mechanism, completing the polishing of the inner and outer walls of the stainless steel pipe.
