Description

Technical Field

[0001] This application relates to the technical field of bent pipe polishing, and in particular to an auxiliary device for surface polishing of titanium bent pipes. Background Art

[0002] Since titanium has better corrosion resistance compared to other metals, titanium pipes made of it are commonly used in corrosive industries such as chemical engineering and petroleum. During the laying process of pipelines, they usually include right angles, bends, etc. according to the design route. At these places, straight pipes are usually connected through straight pipes and bent pipes to complete the laying of the pipeline. Currently, when processing bent pipes, they are usually formed by extrusion, casting, etc. of straight pipes, resulting in a relatively high surface roughness. After forming, it is necessary to polish their surfaces.

[0003] Due to the special structure of bent pipes, they usually cannot be clamped on a polishing machine for mechanical operation like straight pipes. Currently, workers hold the bent pipes by hand and use polishing wheels for polishing operations. As shown in the instruction manual appendix Figure 1-2 As shown, the polishing wheel is usually assembled on the rotating shaft of the driving motor and suspended outside the driving motor. Due to the suspended setting, the polishing wheel can be used to polish product components of any structure, such as bent pipes. When polishing a bent pipe, since the bent pipe is usually used for connecting the straight pipe ports at both ends, the overall arc length is relatively short, and its outer shape structure has a circumferential surface structure and an arc surface structure in the length direction. Therefore, when polishing a bent pipe, as Figure 2 shown, workers hold both ends of the bent pipe by hand and directly lift the outer circumferential surface of the bent pipe to contact the polishing wheel for polishing. Due to the structural characteristics of the bent pipe, during polishing, the operator needs to rotate the bent pipe in the circumferential direction shown by arrow a and rotate it in the arc length direction shown by arrow b to completely polish the surface of the bent pipe.

[0004] Currently, during the manual polishing process of holding the bent pipe, since the metal (titanium) itself is relatively hard, during the polishing operation, the operation time spent is relatively long. The operator needs to resist the force of the high-speed rotation of the polishing wheel on the bent pipe during the entire polishing process, which will cause a relatively large physical burden. At the same time, due to the increase in the operation burden, during the manual support operation, the polishing depth will be inconsistent, affecting the surface flatness of the polished bent pipe. In addition, during the operation, it is also necessary to drive the complete circumferential rotation and rotation in the arc length direction, further increasing the operation difficulty and unable to guarantee the surface quality of the polished bent pipe. Summary of the Invention

[0005] In view of the above problems, the present application aims to provide an auxiliary device for surface polishing of titanium elbow pipes, which can adjust the polishing position of the elbow pipe while supporting the elbow pipe, solve the problem of excessive physical burden during manual operation, and the problem of inconsistent polishing depth caused by the artificially supported suspension of the held elbow pipe. On the basis of improving the operation efficiency, the polishing quality is further improved.

[0006] In order to achieve the above object, the technical solution adopted in the present application is as follows: An auxiliary device for surface polishing of titanium elbow pipes, the surface polishing of titanium elbow pipes includes a polishing wheel, and is characterized in that: the auxiliary device is arranged on one side where the titanium elbow pipe contacts the polishing wheel, and the auxiliary device includes a support member, and an assembly member connected to the support member and connected to the titanium elbow pipe, and the assembly member is adjustably connected to the support member.

[0007] Preferably, the support member is a support rod; the assembly member is a collar that is hinged to the support rod along the axial direction of the polishing wheel and is movably sleeved on the titanium elbow pipe.

[0008] Preferably, the support rod is of a telescopic rod structure.

[0009] Preferably, ball bearings that are in rolling contact with the titanium elbow pipe are evenly distributed on the inner circumferential surface of the collar.

[0010] The beneficial effect of the present application is that: the auxiliary device is arranged on one side where the titanium elbow pipe contacts the polishing wheel, and it can adjust the polishing position of the elbow pipe, bring its different surface positions into contact with the polishing wheel for polishing, so as to complete the complete polishing operation of the circumferential surface of the elbow pipe. At the same time, under the support of the support member and the assembly member on the elbow pipe, the problem of excessive physical burden during manual operation and the problem of inconsistent polishing depth caused by the artificially supported suspension of the held elbow pipe are solved. On the basis of improving the operation efficiency, the polishing quality is further improved. Description of the Drawings

[0020] In order to enable ordinary technicians in the art to better understand the technical solution of this application, the technical solution of this application will be further described below in conjunction with the drawings and embodiments.

[0021] Refer to Figures 1 to 8 A surface polishing assistance device for a titanium elbow pipe shown. The surface polishing of the titanium elbow pipe includes a polishing wheel 1, and the structure is as Figure 1-2 shown. It is assembled on the rotating shaft of the driving motor and suspended outside the driving motor. Currently, when performing the polishing operation of the elbow pipe, as Figure 2 shown, manually hold both ends of the elbow pipe and directly lift the outer peripheral surface of the elbow pipe to contact the polishing wheel for polishing. In order to solve the problems of the increased physical burden during the current elbow pipe polishing, the inconsistent polishing depth, and the influence on the surface quality of the elbow pipe after polishing, this application is provided with an assistance device, as Figure 4 shown. The assistance device is arranged on the side where the titanium elbow pipe contacts the polishing wheel 1, and includes a support member, and an assembly member connected to the support member and connected to the titanium elbow pipe, and the assembly member is adjustably connected to the support member. Among them, the elbow pipe to be polished is assembled and connected through the assembly member, and the elbow pipe is supported by the support member to contact the polishing wheel. And because the assembly member is adjustably connected to the support member, the polishing position of the elbow pipe can be adjusted, that is, different surface positions of it are contacted with the polishing wheel 1 for polishing, so as to complete the complete polishing operation of the circumferential surface of the elbow pipe. At the same time, under the support of the support member and the assembly member for the elbow pipe, the problem of the excessive physical burden during manual operation and the inconsistent polishing depth caused by the artificially supported and suspended elbow pipe held are solved. On the basis of improving the operation efficiency, the polishing quality is further improved.

[0022] Specifically, as Figures 3-4As shown, the support member is a support rod 2, which can preferably be fixedly arranged on the ground on one side of the polishing wheel 1. The assembly member is a collar 3 that is hingedly connected to the support rod 2 along the axial direction of the polishing wheel 1 and is movably sleeved on the titanium elbow pipe. The inner diameter of the collar 3 is slightly larger than the outer diameter of the elbow pipe, facilitating the circumferential rotation and the rotation in the arc length direction during the polishing process of the elbow pipe. During the polishing operation, the elbow pipe is threaded through the collar 3 for supporting the elbow pipe. By circumferentially rotating the elbow pipe in the collar 3 and rotating it in the arc length direction, different positions of the elbow pipe can be brought into contact with the polishing wheel 1, thereby achieving a complete polishing operation on the circumferential surface of the elbow pipe in the supported state. The collar 3 is hingedly connected to the support rod 2, and driving the rotation of the collar 3 can drive the rotation of the elbow pipe in the arc length direction, improving the flexibility of the polishing operation.

[0023] After the elbow pipe changes its polishing position during the polishing process, the distance between different circumferential surface positions of the elbow pipe and the polishing wheel 1 will change. Therefore, to adjust the contact between the surface of the elbow pipe and the polishing wheel 1 in real time, as Figures 5-6 shown, the support rod 2 is of a telescopic rod structure. After adjusting the polishing position of the polishing wheel 1, by adjusting the forward and backward telescoping of the support rod 2, the surface of the elbow pipe is always in contact with the polishing wheel 1, ensuring the smooth progress of the polishing operation.

[0024] The preferred polishing operation method is as follows: Thread one end of the elbow pipe into the collar 3 for support, adjust the length of the support rod 2, and rotate the collar 3 so that one side of the elbow pipe is in contact with the polishing wheel 1. Then, continuously rotate the elbow pipe circumferentially during the polishing process for circumferential polishing operation, and at the same time drive the elbow pipe to rotate in the arc length direction of the elbow pipe, and then complete the complete polishing of the circumferential surface of the elbow pipe in a spiral continuous polishing manner. During the polishing process, through the articulated rotation of the collar 3 and the telescopic adjustment of the support rod 2, the polishing position of the elbow pipe is adjusted in real time. Through this spiral polishing method, it is possible to avoid unpolished areas on the surface of the elbow pipe, ensuring the integrity of the polishing operation of the elbow pipe. Under the action of supporting the elbow pipe, the physical burden of manual operation is reduced, and thus the polishing depth can be effectively guaranteed, improving the consistency of surface polishing.

[0025] During the above-mentioned polishing process of the elbow pipe, the elbow pipe needs to continuously adjust its position compared to the collar 3. Therefore, to avoid the frictional resistance and frictional wear between the elbow pipe and the inner wall of the collar 3, as Figures 7-8 shown, ball bearings 4 that are in rolling contact with the titanium elbow pipe are evenly distributed (embedded) on the inner circumferential surface of the collar 3. When driving the circumferential rotation and the rotation in the arc length direction of the elbow pipe, the elbow pipe is in rolling contact with the collar 3 through the ball bearings 4, thereby effectively reducing the frictional resistance and frictional wear during the adjustment of the elbow pipe and improving the convenience of the operation.

[0026] The principle of this application is as follows: On one side of the polishing wheel, a telescopic support rod 2 is provided. A collar 3 is horizontally hinged on the support rod 2, and a plurality of balls 4 are evenly distributed on the inner wall of the collar 3. When polishing a bent pipe, one end of the bent pipe is inserted into the collar 3 for support. The length of the support rod 2 is adjusted, and the collar 3 is rotated so that one side of the bent pipe contacts the polishing wheel 1. Then, during the polishing process, the bent pipe is continuously rotated circumferentially for circumferential polishing operations, and at the same time, the bent pipe is driven to rotate in the arc length direction of the bent pipe, thereby completing the complete polishing of the circumferential surface of the bent pipe in a spiral continuous polishing manner. During the polishing process, the polishing position of the bent pipe is adjusted in real time through the articulated rotation of the collar 3 and the telescopic adjustment of the support rod 2.

[0027] The above shows and describes the basic principle, main features and advantages of this application. Without departing from the spirit and scope of this application, various changes and improvements will occur to this application, and these changes and improvements all fall within the scope of this application claimed.
