Description

Technical Field

[0001] This utility model relates to the field of steel pipe bending technology, and in particular to an adaptive stainless steel pipe bending device. Background Technology

[0002] A steel pipe bending device is an auxiliary device used to bend steel pipes during use. In traditional bending machines, the steel pipe is first clamped into two limiting angle irons on the surface of the bending machine, and then inserted into the bending frame. The rotation of the bending frame will cause the steel pipe to bend and be processed into the required shape and specifications.

[0003] Existing technologies, such as Chinese Patent Publication No. CN222036563U, disclose a bending device for building steel pipes, including a bending machine. A controller is fixedly connected to the surface of the bending machine, a bending frame is provided on the surface of the bending machine, and a fixing device is provided near the bending frame on the surface of the bending machine. The fixing device includes a servo motor, which is fixedly connected to the surface of the bending machine. A screw is fixedly connected to the output end of the servo motor, and a fixing plate is fixedly connected to the surface of the bending machine. One end of the screw is rotatably connected to the surface of the fixing plate. This invention solves the problem in existing technologies where, during the bending process, the steel pipe is difficult to maintain stability under the force of the bending frame, causing the steel pipe clamped between angle irons to shake or even break off, affecting the bending effect and potentially leading to safety accidents, thus reducing the effectiveness of the bending machine. However, this invention can only position and bend pipes of specific sizes and specifications, limiting its applicability.

[0004] To address the problem that stainless steel pipe bending devices are not convenient for positioning and bending pipes of different sizes, most existing bending devices can only position and bend pipes of specific sizes and specifications, which is not very applicable. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing stainless steel pipe bending devices are not convenient for positioning and bending pipes of different sizes, and to propose an adaptive stainless steel pipe bending device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive stainless steel pipe bending device, comprising a workbench and a bending mechanism, wherein the bending mechanism is disposed on the surface of the workbench; The bending mechanism includes a drive assembly, a positioning assembly, and an adjustment assembly. The drive assembly includes a motor, which is fixedly mounted on the surface of the worktable. A screw is fixedly connected to the output end of the motor, and a movable frame is threadedly connected to the surface of the screw. A limit groove is formed on the surface of the worktable, and the movable frame is slidably connected to the surface of the limit groove. The positioning components are provided in three sets, one of which is fixed to the surface of the movable frame; The positioning component includes a frustum and a motor. The motor is fixedly installed on the inner wall of the frustum. The output end of the motor is fixedly connected to a screw. The surface of the screw is threadedly connected to the frustum. The surface of the frustum is fixedly connected to a guide rod. The frustum and the guide rod are slidably connected.

[0007] Furthermore, the first and second frustums are adapted to each other, and soft pads are fixedly connected to the surfaces of both the first and second frustums.

[0008] Furthermore, the surface of the cushion is provided with anti-slip textures, which are multiple sets and evenly distributed around the circumference.

[0009] Furthermore, the adjustment assembly includes a bidirectional threaded rod, which is rotatably connected to the inner wall of the worktable, and a movable block is threadedly connected to the surface of the bidirectional threaded rod.

[0010] Furthermore, the number of the movable blocks is two sets, which are symmetrically arranged, and a set of positioning components is fixed on the surface of each of the two sets of movable blocks.

[0011] Furthermore, the surface of the worktable is provided with a guide groove, and the movable block is slidably connected to the surface of the guide groove.

[0012] Furthermore, a motor three is fixedly mounted on the surface of the workbench, a worm gear is fixedly connected to the output end of the motor three, a worm wheel is fixedly connected to the surface of the bidirectional threaded rod, and the surfaces of the worm gear and the worm wheel are meshed together.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a bending mechanism, the pipe fitting is placed on the worktable, positioned between the positioning components on the movable block and the positioning components on the movable frame. The second motor is started to rotate the second screw, causing the second truncated cone to slide along the guide rod to an appropriate height to accommodate pipe fittings of different specifications. Then, the third motor is started to rotate the worm gear, which drives the worm wheel and the bidirectional threaded rod to rotate, causing the two sets of movable blocks to move towards each other or away from each other along the guide groove, thereby adjusting the distance between the two sets of positioning components. This allows for adjustment of the bending angle of the pipe fitting, and the self-locking function of the worm gear and worm wheel ensures sufficient stability of the movable block. Finally, the first motor is started to rotate the first screw, causing the movable frame to slide along the limiting groove, so that the positioning components on the movable frame and the positioning components on the movable block stably clamp the pipe fitting. As the movable frame continues to move, the pipe fitting can be bent.

[0014] 2. In this utility model, by setting a bending mechanism, it can adapt to pipes of different sizes during positioning and bend at different angles as needed. Moreover, the structure is simple and the operation is convenient, which effectively improves the applicability of the equipment. Attached Figure Description

[0017] Please see Figures 1-5 This utility model provides a technical solution: an adaptive stainless steel pipe bending device, including a workbench 1 and a bending mechanism 2, wherein the bending mechanism 2 is disposed on the surface of the workbench 1.

[0018] The specific setup and function of its bending mechanism 2 will be explained below.

[0019] In this embodiment: the bending mechanism 2 includes a drive assembly 21, a positioning assembly 22 and an adjustment assembly 23. The drive assembly 21 includes a motor 211, which is fixedly mounted on the surface of the workbench 1. The output end of the motor 211 is fixedly connected to a screw 212. The surface of the screw 212 is threadedly connected to a movable frame 213. A limit groove 214 is provided on the surface of the workbench 1. The movable frame 213 is slidably connected to the surface of the limit groove 214. The positioning components 22 are provided in three sets, one of which is fixed to the surface of the movable frame 213; The positioning component 22 includes a first truncated cone 221 and a second motor 222. The second motor 222 is fixedly installed on the inner wall of the first truncated cone 221. The output end of the second motor 222 is fixedly connected to a second screw 223. The surface of the second screw 223 is threadedly connected to a second truncated cone 224. The surface of the first truncated cone 221 is fixedly connected to a guide rod 225. The second truncated cone 224 and the surface of the guide rod 225 are slidably connected.

[0020] The effects achieved by the above components are as follows: When the motor 211 is started, the screw 212 rotates, causing the movable frame 213 to slide along the limit groove 214, so that the positioning component 22 on it moves and cooperates with the other two sets of positioning components 22 to perform positioning and bending operations. The frustum 1 221 and frustum 224 are set to facilitate the positioning of the pipe fittings. The motor 222, the screw 223, and the guide rod 225 are set to rotate when the motor 222 is started, causing the frustum 224 to slide along the guide rod 225 to accommodate pipe fittings of different specifications.

[0021] Specifically, frustum 1 221 and frustum 2 224 are compatible, and soft pads 226 are fixedly connected to the surfaces of frustum 1 221 and frustum 2 224.

[0022] The effect achieved by the above components is as follows: the soft pad 226 is set to prevent the first frustum 221 and the second frustum 224 from coming into hard contact with the pipe during the bending process, which would cause damage to the pipe.

[0023] Specifically, the surface of the pad 226 is provided with anti-slip textures 227, which are multiple sets and evenly distributed around the circumference.

[0024] The effect achieved by the above components is as follows: the anti-slip texture 227 is set to increase friction and prevent slippage after the pipe is positioned.

[0025] Specifically, the adjustment component 23 includes a bidirectional threaded rod 231, which is rotatably connected to the inner wall of the worktable 1, and a movable block 232 is threadedly connected to the surface of the bidirectional threaded rod 231.

[0026] The effect achieved by the above components is that the bidirectional threaded rod 231 and the movable block 232 are set so that when the bidirectional threaded rod 231 rotates, the two sets of movable blocks 232 can move towards each other or away from each other.

[0027] Specifically, there are two sets of movable blocks 232 arranged symmetrically, and a set of positioning components 22 are fixed on the surface of each set of movable blocks 232.

[0028] The effect achieved by the above components is as follows: the two sets of movable blocks 232 and the positioning components 22 thereon are set so that when the two sets of movable blocks 232 move towards each other or away from each other, the distance between the two sets of positioning components 22 can be adjusted, and thus can be used in conjunction with the positioning components 22 on the movable frame 213 to bend the pipe at different angles.

[0029] Specifically, the surface of the workbench 1 is provided with a guide groove 233, and the movable block 232 is slidably connected to the surface of the guide groove 233.

[0030] The effect achieved by the above components is that the guide groove 233 provides guidance and limit for the movement of the movable block 232, preventing it from rotating with the bidirectional threaded rod 231.

[0031] Specifically, a motor 234 is fixedly mounted on the surface of the workbench 1, a worm gear 235 is fixedly connected to the output end of the motor 234, a worm wheel 236 is fixedly connected to the surface of the bidirectional threaded rod 231, and the surfaces of the worm gear 235 and the worm wheel 236 are meshed together.

[0032] The effect achieved by the above components is as follows: the motor 234, worm 235 and worm wheel 236 are set so that when the motor 234 is started, the worm 235 can drive the worm wheel 236 and the double-threaded rod 231 to rotate, and the self-locking function of the worm wheel 236 and worm 235 can be used to keep the moving block 232 sufficiently stable.

[0033] Working principle: By setting up bending mechanism 2, the pipe fitting is placed on workbench 1, positioning it between positioning component 22 on movable block 232 and positioning component 22 on movable frame 213. Motor 222 is started to rotate screw 223, causing frustum 224 to slide along guide rod 225 to an appropriate height to accommodate pipe fittings of different specifications. Then, motor 324 is started to drive worm gear 235 to rotate worm wheel 236 and double-threaded rod 231, causing the two sets of movable blocks 232 to move towards each other along guide groove 233. Moving in opposite directions allows for adjustment of the distance between the two sets of positioning components 22, enabling adjustment of the bending angle of the pipe fitting. The self-locking function of the worm gear 236 and worm 235 ensures sufficient stability of the movable block 232. Finally, the motor 211 is started to rotate the screw 212, causing the movable frame 213 to slide along the limiting groove 214. This allows the positioning components 22 on the movable frame 213 and the positioning components 22 on the movable block 232 to stably clamp the pipe fitting. As the movable frame 213 continues to move, the pipe fitting can be bent.

[0034] By setting up the bending mechanism 2, it can adapt to pipes of different sizes during positioning and bend them at different angles as needed. The structure is simple and the operation is convenient, which effectively improves the applicability of the equipment.
