Description

Technical Field

[0001] The present application relates to the field of metal seamless pipes, and in particular to a wear-resistant aluminum alloy seamless pipe. Background Art

[0002] Aluminum alloy seamless pipe refers to a kind of pipe that will not produce gaps in the production process. Aluminum alloy seamless pipe is divided into hot-rolled extruded seamless pipe and cold-drawn seamless pipe due to different manufacturing processes.

[0003] The production process of aluminum alloy seamless pipes is basically hot rolling: round tube billet → heating → perforation → three-roller oblique rolling, continuous rolling or extrusion → tube removal → sizing (or reducing diameter) → cooling → billet tube → straightening → water pressure test (or flaw detection) → marking → storage. Traditional aluminum alloy seamless pipes are insufficient in strength and wear resistance. They are easily bent and broken when squeezed or collided by external forces, and are easily damaged after long-term wear. Surface strengthening treatment, alloy composition optimization and other methods are often used.

[0004] The existing method to solve the shortcomings of aluminum alloy seamless pipes in strength and wear resistance is generally to cover the aluminum alloy seamless pipes with a protective layer after the existing aluminum alloy seamless pipes are produced. Although this can solve the problems of strength and wear resistance of the aluminum alloy seamless pipes, when the aluminum alloy seamless pipes are in use, only a certain position needs to be protected, but the protection position cannot be determined during production, so the entire section of the aluminum alloy seamless pipe needs to be protected, which will increase the overall weight of the aluminum alloy seamless pipes and cause unnecessary waste. Utility Model Content

[0005] The purpose of the present application is to solve the problem raised in the above-mentioned background technology that when the aluminum alloy seamless pipe is in use, only a certain position needs to be protected, but the protection position cannot be determined during production, so the entire section of the aluminum alloy seamless pipe needs to be protected, which will increase the overall weight of the aluminum alloy seamless pipe and cause unnecessary waste. The present application provides a wear-resistant aluminum alloy seamless pipe.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A wear-resistant aluminum alloy seamless pipe comprises an aluminum alloy seamless pipe body, on which a plurality of protective sleeves are arranged, the plurality of protective sleeves are sleeved on the aluminum alloy seamless pipe body, a splicing mechanism is arranged between adjacent protective sleeves, and a fixing mechanism is arranged between adjacent protective sleeves.

[0008] By adopting the above technical scheme, a corresponding number of protective sleeves are selected according to the length of the aluminum alloy seamless pipe body, and then the protective sleeves are sequentially sleeved on the aluminum alloy seamless pipe body, and the adjacent protective sleeves are connected by a splicing mechanism, and then the adjacent protective sleeves are fixed on the aluminum alloy seamless pipe body by a fixing mechanism, so that the number of protective sleeves and the area to be protected can be conveniently selected according to actual needs, and the protective sleeves can be divided into several pieces for easy transportation, while reducing the trouble of splicing the protective sleeves.

[0009] Furthermore, the splicing mechanism includes a plurality of splicing blocks fixed at one end of the protective sleeve, the plurality of splicing blocks are distributed in a circle, a connecting block is fixed on the splicing block, a clamping block is fixed on the connecting block, and one end of the protective sleeve is provided with a plurality of connecting grooves distributed in a circle, the connecting grooves correspond to the connecting blocks, a clamping groove is provided on the inner wall of the connecting groove, the clamping groove corresponds to the clamping block, and the clamping groove passes through the protective sleeve.

[0010] By adopting the above technical solution, when two protective sleeves are close to each other, the splicing block on one of the protective sleeves drives the connecting block, and the connecting block drives the clamping block, so that the clamping block is inserted into the connecting groove on the other protective sleeve, and then the clamping block is clamped in the corresponding clamping groove, so that the number of protective sleeves can be conveniently selected according to actual needs, and the protective sleeves can be modularized for easy transportation.

[0011] Furthermore, a clamping bevel is provided on a surface of the clamping block away from the connecting block, and the clamping bevel corresponds to the edge of the connecting groove.

[0012] By adopting the above technical solution, when the connecting block drives the clamping block to enter the connecting groove, the clamping inclined surface on the clamping block contacts the edge of the connecting groove, and the clamping block enters the connecting groove under the action of the inclined surface, thereby making it easier for the clamping block to enter the connecting groove and facilitating the clamping block to be clamped into the clamping groove.

[0013] Furthermore, the fixing mechanism includes a fixing threaded ring sleeved on a plurality of splicing blocks, a plurality of the splicing blocks are provided with threaded grooves, the fixing threaded ring is threadedly connected to a plurality of circumferentially distributed splicing blocks, a plurality of circumferentially distributed interference blocks are fixed to one end of the protective sleeve away from the splicing block, a interference slope is provided on the interference block, the interference slope corresponds to the fixing threaded ring, and a plurality of the interference blocks are staggeredly distributed with a plurality of splicing blocks.

[0014] By adopting the above technical solution, when two adjacent protective sleeves are close to each other, the splicing block and the resistance block are plugged together in a staggered manner, and then the fixed threaded ring is twisted to allow the fixed threaded ring to squeeze the resistance block, so that the resistance block can be in contact with the surface of the aluminum alloy seamless pipe body, reducing the movement of the protective sleeve.

[0015] Furthermore, a limiting block is fixed to one end of the splicing block close to the connecting block, and the limiting block corresponds to the fixed threaded ring.

[0016] By adopting the above technical solution, when the fixed thread ring is screwed, the fixed thread ring moves on the splicing block, and the limit block on the splicing block restricts the fixed thread ring, thereby reducing the possibility of the fixed thread ring detaching from the splicing block when the fixed thread ring is screwed.

[0017] Furthermore, a resistance rubber pad is fixed on a surface of the resistance block close to the main body of the aluminum alloy seamless pipe.

[0018] By adopting the above technical solution, when the resistance block is in contact with the aluminum alloy seamless pipe body, the resistance rubber pad on the resistance block is in contact with the surface of the aluminum alloy seamless pipe body, thereby increasing the friction force of the resistance block in contact with the surface of the aluminum alloy seamless pipe body.

[0019] Furthermore, a butt tip is fixed to one end of the abutment block away from the protective sleeve.

[0020] By adopting the above technical solution, when adjacent protective sleeves are close to each other, the butt joint tip on the abutment block allows the abutment block to be more easily inserted into the gap between adjacent splicing blocks, thereby making it easier to plug the splicing block and the abutment block.

[0021] Furthermore, the protective sleeve is provided with evenly distributed hollow grooves, and the hollow grooves penetrate the protective sleeve.

[0022] By adopting the above technical solution, evenly distributed hollow grooves are opened on the protective sleeve, so that the surface of the protective sleeve forms a mesh, thereby reducing the overall weight of the protective sleeve and reducing the possibility of the protective sleeve compressing the aluminum alloy seamless sleeve body.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application, when a plurality of protective sleeves are sleeved on the main body of the aluminum alloy seamless pipe, the connecting blocks and connecting grooves on adjacent protective sleeves are aligned. When the two protective sleeves are close to each other, the splicing block on one of the protective sleeves drives the connecting block, and the connecting block drives the clamping block, so that the clamping block is inserted into the connecting groove on the other protective sleeve, and then the edge of the connecting groove conflicts with the clamping inclined surface on the clamping block. Under the restriction of the clamping inclined surface, the clamping block and the connecting block enter the connecting groove together, and after the clamping block moves to the position of the clamping groove, the clamping block is clamped into the clamping groove, the clamping block restricts the connecting block, and the connecting block restricts the splicing block, so that adjacent protective sleeves are restricted together, thereby achieving the purpose of being able to conveniently select the number of protective sleeves and the area to be protected according to actual needs, reducing unnecessary waste, dividing the protective sleeves into several pieces for convenient transportation, and reducing the trouble of splicing the protective sleeves.

[0025] 2. The present application connects two protective sleeves together by twisting a fixed threaded ring to move the threaded ring on a plurality of joint blocks, and then the threaded ring squeezes the resistance inclined surface on the resistance block to make the resistance block approach toward the main body of the aluminum alloy seamless pipe, so that the resistance rubber pad on the resistance block is in resistance to the surface of the main body of the aluminum alloy seamless pipe, and the resistance block cannot move on the main body of the aluminum alloy seamless pipe due to the influence of the extrusion friction force, and the adjacent protective sleeves are fixed on the main body of the aluminum alloy seamless pipe, thereby achieving the purpose of reducing the possibility of the protective sleeve moving back and forth when the protective sleeve is sleeved on the main body of the aluminum alloy seamless pipe, and conveniently fixing the protective sleeve at the corresponding position.

[0033] The following is combined with Figure 1 —5 further describes this application in detail.

[0034] The embodiment of the present application discloses a wear-resistant aluminum alloy seamless pipe.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A wear-resistant aluminum alloy seamless pipe comprises an aluminum alloy seamless pipe body 1, a plurality of protective sleeves 2 are arranged on the aluminum alloy seamless pipe body 1, the plurality of protective sleeves 2 are sleeved on the aluminum alloy seamless pipe body 1, a splicing mechanism 3 is arranged between adjacent protective sleeves 2, and a fixing mechanism 4 is arranged between adjacent protective sleeves 2.

[0036] When using the aluminum alloy seamless tube body, first select the corresponding number of protective tubes 2 according to the length of the aluminum alloy seamless tube body 1, and then sequentially sleeve the protective tubes 2 on the aluminum alloy seamless tube body 1, and connect the adjacent protective tubes 2 by means of the splicing mechanism 3, so that the adjacent protective tubes 2 are combined together, and then the adjacent protective tubes 2 are fixed on the aluminum alloy seamless tube body 1 by means of the fixing mechanism 4, so as to reduce the possibility of the protective tubes 2 moving on the aluminum alloy seamless tube body 1, and then install the aluminum alloy seamless tube body 1 at the required position for use, by sleeved a number of protective tubes 2 on the aluminum alloy seamless tube body 1 before using the aluminum alloy seamless tube body 1, and then connect the adjacent protective tubes 2 together by means of the splicing mechanism 3, and then fix the protective tubes 2 on the aluminum alloy seamless tube body 1 by means of the fixing mechanism 4, so that the number of protective tubes 2 and the area to be protected can be conveniently selected according to actual needs, and unnecessary waste can be reduced, and dividing the protective tubes 2 into several pieces can also facilitate transportation, while reducing the trouble of splicing the protective tubes 2.

[0037] Reference Figure 3 , Figure 4 and Figure 5The splicing mechanism 3 includes a plurality of splicing blocks 31 fixed at one end of the protective sleeve 2, the plurality of splicing blocks 31 are distributed in a circle, a connecting block 32 is fixed on the splicing block 31, a clamping block 33 is fixed on the connecting block 32, and a plurality of connecting grooves 34 distributed in a circle are opened at one end of the protective sleeve 2, the connecting groove 34 corresponds to the connecting block 32, a clamping groove 35 is opened on the inner wall of the connecting groove 34, the clamping groove 35 corresponds to the clamping block 33, and the clamping groove 35 passes through the protective sleeve 2.

[0038] In addition, a clamping inclined surface is formed on a surface of the clamping block 33 away from the connecting block 32 , and the clamping inclined surface corresponds to the edge of the connecting groove 34 .

[0039] When a plurality of protective sleeves 2 are sleeved on the aluminum alloy seamless pipe body 1, the connecting blocks 32 and the connecting grooves 34 on the adjacent protective sleeves 2 are aligned. When the two protective sleeves 2 are close to each other, the splicing block 31 on one of the protective sleeves 2 drives the connecting block 32, and the connecting block 32 drives the clamping block 33, so that the clamping block 33 is inserted into the connecting groove 34 on the other protective sleeve 2, and then the edge of the connecting groove 34 conflicts with the clamping inclined surface on the clamping block 33. Under the restriction of the clamping inclined surface, the clamping block 33 and the connecting block 32 are moved together. After the clamping block 33 is inserted into the connecting groove 34 and the clamping block 33 is moved to the position of the clamping groove 35, the clamping block 33 is clamped into the clamping groove 35, the clamping block 33 restricts the connecting block 32, and the connecting block 32 restricts the splicing block 31, so that the adjacent protective sleeves 2 are restricted together. After a number of protective sleeves 2 are sleeved on the aluminum alloy seamless pipe body 1, the adjacent protective sleeves are restricted by the clamping block 33 and the clamping groove 35, so that the number of protective sleeves 2 can be conveniently selected according to actual needs, and the protective sleeves 2 can be modularized for easy transportation.

[0040] Reference Figure 2 and Figure 5 The fixing mechanism 4 includes a fixing threaded ring 41 sleeved on a plurality of splicing blocks 31, a threaded groove 42 is provided on the plurality of splicing blocks 31, the fixing threaded ring 41 is threadedly connected with a plurality of circumferentially distributed splicing blocks 31, and a plurality of circumferentially distributed interference blocks 43 are fixed to one end of the protective sleeve 2 away from the splicing block 31, an interference slope is provided on the interference block 43, and the interference slope corresponds to the fixing threaded ring 41, and a plurality of interference blocks 43 are staggeredly distributed with a plurality of splicing blocks 31.

[0041] In addition, a limiting block 44 is fixed to one end of the splicing block 31 close to the connecting block 32 , and the limiting block 44 corresponds to the fixed threaded ring 41 .

[0042] In addition, a resistance rubber pad 45 is fixed on a surface of the resistance block 43 close to the aluminum alloy seamless pipe body 1 .

[0043] Furthermore, a butt tip 46 is fixed to one end of the abutment block 43 away from the protection sleeve 2 .

[0044] When the two protective sleeves 2 are connected together, the splicing blocks 31 and the abutment blocks 43 are inserted together in an interlaced manner, and the butt tips 46 on the abutment blocks 43 make it easier to insert the abutment blocks 43 into the gaps between the adjacent splicing blocks 31. The fixed threaded ring 41 is twisted to allow the threaded ring to move on several splicing blocks 31. At the same time, the limit block 44 restricts the moving fixed threaded ring 41 to reduce the possibility of the fixed threaded ring 41 being separated from the corresponding splicing block 31. Then, the threaded ring squeezes the abutment slope on the abutment block 43 to allow the abutment block 43 to move toward the direction of the aluminum alloy seamless pipe body 1. Get close to make the resistance rubber pad 45 on the resistance block 43 resist against the surface of the aluminum alloy seamless pipe body 1, so that the resistance block 43 cannot move on the aluminum alloy seamless pipe body 1 due to the influence of the extrusion friction force, and the adjacent protective sleeve 2 is fixed on the aluminum alloy seamless pipe body 1, and the resistance inclined surface on the resistance block 43 is squeezed by using the fixed threaded ring 41 to make the resistance block 43 resist against the aluminum alloy seamless pipe body 1, so that when the protective sleeve 2 is sleeved on the aluminum alloy seamless pipe body 1, the possibility of the protective sleeve 2 moving back and forth is reduced, and the protective sleeve 2 is conveniently fixed at the corresponding position.

[0045] Reference Figure 1 and Figure 2 The protective sleeve 2 is provided with evenly distributed hollow grooves, which penetrate the protective sleeve 2. When the protective sleeve 2 is produced, evenly distributed hollow grooves are provided on the protective sleeve 2, so that the surface of the protective sleeve 2 forms a mesh, reducing the overall area of ​​the protective sleeve 2 and the overall weight of the protective sleeve 2. By providing evenly distributed hollow grooves on the protective sleeve 2 and reducing the overall area of ​​the protective sleeve 2, the overall weight of the protective sleeve 2 can be reduced, and the possibility of the protective sleeve 2 pressing the main body of the aluminum alloy seamless sleeve can be reduced.

[0046] Working principle: When using the aluminum alloy seamless sleeve body, first select the corresponding number of protective sleeves 2 according to the length of the aluminum alloy seamless pipe body 1, and then put the protective sleeves 2 on the aluminum alloy seamless pipe body 1 in sequence, and make the connecting blocks 32 and connecting grooves 34 on adjacent protective sleeves 2 correspond to each other. When the two protective sleeves 2 are close to each other, the splicing block 31 on one of the protective sleeves 2 drives the connecting block 32, and the connecting block 32 drives the clamping block 33, so that the clamping block 33 is inserted into the connecting groove 34 on the other protective sleeve 2. At the same time, the resistance block 43 and the splicing are staggered and inserted together, and then the edge of the connecting groove 34 is in conflict with the clamping bevel on the clamping block 33. Under the restriction of the clamping bevel, the clamping block 33 and the connecting block 32 enter the connecting groove 34 together. After the clamping block 33 moves to the position of the clamping groove 35, the clamping block 33 is clamped in. The clamping block 33 is used to restrict the connecting block 32, and the connecting block 32 is used to restrict the splicing block 31, so that the adjacent protective sleeves 2 are restricted together, and the fixed threaded ring 41 is twisted to allow the threaded ring to move on several splicing blocks 31. At the same time, the limit block 44 restricts the moving fixed threaded ring 41 to reduce the possibility of the fixed threaded ring 41 detaching from the corresponding splicing block 31. Then the threaded ring squeezes the resistance inclined surface on the resistance block 43, so that the resistance block 43 approaches the aluminum alloy seamless pipe body 1, and the resistance rubber pad 45 on the resistance block 43 is in contact with the surface of the aluminum alloy seamless pipe body 1, so that the resistance block 43 cannot move on the aluminum alloy seamless pipe body 1 due to the extrusion friction force, and the adjacent protective sleeves 2 are fixed on the aluminum alloy seamless pipe body 1. Finally, the protected aluminum alloy seamless pipe body 1 is installed in the required position for use.
