Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to an explosion-proof pipe bending sander. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece, thereby obtaining a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the surface of a workpiece.

[0003] Existing sanders for polishing the outer surface of round tubes are diverse and relatively mature. They typically use grinding wheels or belts for polishing, and their structure generally consists of a transmission mechanism and a polishing mechanism. The transmission mechanism transports the round tube and, considering the characteristics of round tubes, generally has a structure with a motor-driven turntable, with the round tube loaded in the center of the turntable. The polishing mechanism generally consists of a grinding wheel or belt assembly and a drive motor. This mechanism can polish most regular straight round tubes, but it cannot process the outer surface of bent round tubes, such as the outer surface polishing of some automotive guards, motorcycle guards, etc.

[0004] However, in existing technologies, the bends of pipes are usually polished using a combination of machine and manual methods, especially at the corners, where manual polishing is generally used. This method is inefficient and the polishing effect is not ideal. Therefore, we need to propose an explosion-proof pipe bending sander. Utility Model Content

[0005] The purpose of this utility model is to provide an explosion-proof pipe bending sander that facilitates polishing of the bends in pipes without the need for manual polishing, thereby improving the polishing efficiency of pipes and enabling the polishing of pipes of different specifications. This expands the applicability of the device, thereby improving the quality of polished products and reducing the production cost of polishing equipment, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof pipe bending sander, comprising a base, a fixing clamp for positioning the bent pipe mounted on the upper surface of the base, a control box provided on one side of the fixing clamp, a first moving mechanism provided on the upper surface of the base, a second moving mechanism provided on the first moving mechanism, a rotating mechanism provided on the second moving mechanism, a turntable rotatably mounted on the rotating mechanism, a driving mechanism for driving the turntable to rotate on the rotating mechanism, and polishing mechanisms for polishing the bent pipe provided on both sides of the turntable;

[0007] The polishing mechanism includes a bidirectional screw, with adjusting blocks threaded to both ends of the bidirectional screw. One end of the bidirectional screw is fixedly connected to an internal hexagon block. Each set of adjusting blocks has a movable wheel on one side of its opposite side.

[0008] Preferably, the tensioning assembly includes a vertical rod, a slider is slidably disposed on the outer side of the vertical rod, a tensioning wheel is fixedly connected to one side of the slider and is slidably disposed with the sanding belt, and a spring is sleeved on the outer side of the vertical rod.

[0009] Preferably, the turntable includes a disc body, one side of which has a side groove for the sliding of the adjusting block, both sides of which have tension holes for the fixed installation of the upright, the slider is slidably disposed in the tension holes, one side of which has a pipe hole for the passage of the bent pipe, and the outer side of which has a circular groove for the embedding of the internal hexagonal block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model mainly utilizes the cooperation between a first moving mechanism, a second moving mechanism, a rotating mechanism, a drive mechanism, a turntable, and a polishing mechanism. The first moving mechanism, the second moving mechanism, and the rotating mechanism facilitate the adjustment of the position and tilt angle of the turntable, making it easy for the turntable to be perpendicular to the bent pipe. This facilitates the polishing mechanism to polish the bent pipe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: an explosion-proof pipe bending sander, including a base 1, a fixing clamp 8 for positioning the pipe is installed on the upper surface of the base 1, a control box 9 is provided on one side of the fixing clamp 8, a first moving mechanism 2 is provided on the upper surface of the base 1, a second moving mechanism 3 is provided on the first moving mechanism 2, a rotating mechanism 4 is provided on the second moving mechanism 3, a turntable 6 is rotatably provided on the rotating mechanism 4, a driving mechanism 5 for driving the turntable 6 to rotate is provided on the rotating mechanism 4, and polishing mechanisms 7 for polishing the pipe are provided on both sides of the turntable 6. The working principle of the control box 9 controlling the first moving mechanism 2, the second moving mechanism 3, the rotating mechanism 4 and the driving mechanism 5 are all existing technologies and will not be described in detail.

[0022] The polishing mechanism 7 includes a bidirectional screw 74, with adjusting blocks 73 threaded to both ends of the bidirectional screw 74. An internal hexagon block 75 is fixedly connected to one end of the bidirectional screw 74. A movable wheel 76 is provided on the opposite side of each of the two sets of adjusting blocks 73. An abrasive belt 72 is provided on each set of movable wheels 76. The abrasive belt 72 is rotatably equipped with a fixed wheel 71 and a tensioning component. By adjusting the position of the movable wheel 76, the included angle of the corresponding abrasive belt 72 can be changed, thereby facilitating the polishing of bent pipes of different specifications and improving the applicability.

[0023] The tensioning assembly includes a vertical rod 77, a slider 78 slidably disposed on the outer side of the vertical rod 77, a tensioning wheel 710 fixedly connected to one side of the slider 78 and rolled with the sanding belt 72, and a spring 79 sleeved on the outer side of the vertical rod 77. The spring 79 is used to conveniently limit the position of the slider 78, thereby causing the slider 78 to drive the tensioning wheel 710 to tighten the sanding belt 72, so that the sanding belt 72 can polish the bent pipe and improve the polishing effect on the surface of the bent pipe.

[0024] The turntable 6 includes a disc body 61. One side of the disc body 61 has a side groove 63 for the sliding of the adjusting block. Both sides of the disc body 61 have tension holes 64 for the fixed installation of the upright 77. The slider 78 is slidably disposed in the tension holes 64. One side of the disc body 61 has a pipe hole 62 for the passage of the bent pipe. The outer side of the disc body 61 has a circular groove 65 for the insertion of the hexagonal block 75. The side groove 63 facilitates the movement of the adjusting block and limits the angle of the adjusting block to ensure the stability of the movement of the movable wheel 76. At the same time, the tension holes 64 facilitate the installation of the tensioning components.

[0025] The first moving mechanism 2 includes a first screw 22 rotatably disposed in the base 1. One end of the first screw 22 passes through the base 1 and is driven by a first motor 21. A rectangular slot for mounting the first screw 22 is provided on the upper surface of the base 1. The other end of the first screw 22 is connected to a moving block 23. The first motor 21 drives the first screw 22 to adjust the position of the moving block 23, thereby facilitating the polishing of continuous bent pipes and improving the efficiency of polishing bent pipes.

[0026] The second moving mechanism 3 includes a support frame 31 fixedly connected to the upper surface of the moving block 23. Two sets of guide rods 32 are fixedly connected to the inner cavity of the support frame 31. A cylinder 33 is installed on one side of the support frame 31. The position of the disc 61 can be easily adjusted by the cylinder 33, so that the position of the disc 61 can be adjusted as the bending tube polishing position is adjusted. This makes it suitable for polishing discs with different curvatures and improves the applicability.

[0027] The rotating mechanism 4 includes a bottom frame plate 41 slidably mounted on two sets of guide rods 32. A second motor 42 is mounted on the lower surface of the bottom frame plate 41. The output shaft of the second motor 42 is connected to a support plate 43. Two sets of fixing frames 44 are fixedly connected to the upper surface of the support plate 43. A support bearing 45 for rotating the disc 61 is provided between the two sets of fixing frames 44. The second motor 42 drives the support plate 43, which facilitates the rotation of the fixing frames 44. This facilitates the change of the angle of the turntable 6 inside the support bearing 45, so that the bent pipe can pass through the pipe hole 62 and the bent part of the pipe can be polished.

[0028] The drive mechanism 5 includes a third motor 51 mounted on one side of one of the fixed brackets 44. The output shaft of the third motor 51 is connected to a gear 52. The outer side of the disc 61 is provided with teeth 66 that mesh with the gear 52. The third motor 51 drives the gear 52 to rotate, thereby causing the gear 52 to mesh with the teeth 66 on the disc 61, so as to drive the disc 61 to rotate. This facilitates the sanding belt 72 to make circumferential movements along the curved tube, which is convenient for polishing the outer wall of the curved tube and improves its practicality.

[0029] In use, the fixed clamp 8 facilitates the fixation of the bend, ensuring it is parallel to the horizontal plane. The control box 9 operates the first moving mechanism 2, the second moving mechanism 3, the rotating mechanism 4, and the drive mechanism 5. The first motor 21 drives the first screw 22 to adjust the position of the moving block 23, and the cylinder 33 adjusts the position of the rotating mechanism 4, causing the second motor 42 to adjust the angle of the support plate 43. This ensures the turntable 6 is perpendicular to the end of the bend. A wrench rotates the internal hexagonal block 75, causing the bidirectional screw 74 to adjust the distance between the two sets of adjusting blocks. The distance is adjusted to facilitate the passage of the bent tube through the abrasive belt 72 and through the tube hole 62, and to make the abrasive belt 72 contact the outer surface of the bent tube. The third motor 51 is started to drive the gear 52 to mesh with the teeth 66, thereby driving the disc body 61 to rotate. This facilitates the polishing mechanism 7 on the disc body 61 to polish the bent tube, improving the polishing efficiency of the bent tube. Under the action of the control box 9, the first moving mechanism 2, the second moving mechanism 3 and the rotating mechanism 4 are continuously controlled to facilitate the accurate passage of the bent tube through the tube hole 62, thereby improving the polishing effect of the bent tube bending part and improving the polishing quality of the bent tube.
