Description

Technical Field

[0001] The utility model belongs to the technical field of bending for production, and particularly relates to a bending device for the production of heating pipes. Background Art

[0002] A heating pipe is formed by inserting an electric heating wire into a seamless metal pipe (carbon steel pipe, titanium pipe, stainless steel pipe, and copper pipe), filling the gap with magnesium oxide powder having good thermal conductivity and insulation properties, and then shrinking the pipe, and then processing it into various shapes required by users.

[0003] When the existing heating pipes are bent, usually, the operator needs to open the fixed buckle of the bending machine, then place the pipe into it for fixing and bending. After bending, the fixed buckle needs to be opened again to take out the pipe, and a new material needs to be placed into it for work, and so on. For this reason, we provide a bending device for the production of heating pipes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bending device for the production of heating pipes, which bends the pipe through the rotation of the friction ring and the inclination angle of the bending groove, and can be used for pipes of different sizes at the same time, without manual fixing of the pipe, and solves the problems that the existing pipe is placed into it for fixing and bending, and after bending, the fixed buckle needs to be opened again to take out the pipe, and a new material needs to be placed into it for work.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a bending device for the production of heating pipes, including a bending mechanism and a workbench. An adjusting mechanism is arranged at the top of the bending mechanism. A bending groove is slidably connected to the top of the workbench. An installation groove is opened inside the workbench. A motor is fixedly connected to the inner wall of the installation groove. The bottom output end of the motor is fixedly connected to a rotating shaft, and the top of the rotating shaft penetrates the workbench and extends to the outside.

[0007] A rotating table is fixedly connected to the top of the rotating shaft. A friction ring is fixedly connected to the outer surface of the rotating table. A connecting ring is rotatably connected to the outer surface of the rotating shaft. An activity groove is opened inside the connecting ring. There are two activity grooves in total, and the two activity grooves are symmetrically arranged with the rotating shaft as the center. The rotation of the friction ring and the inclination angle of the bending groove are used to bend the pipe, and pipes of different sizes can be used at the same time, without manual fixing of the pipe.

[0008] Further, the parts contained inside the two movable slots are the same. A first spring is fixedly connected inside the movable slot. The bottom of the first spring is fixedly connected with a convex block. A groove is formed in the inner wall of the rotating shaft. When the convex block is snapped into the groove, the rotating shaft can drive the connecting ring to rotate when it rotates.

[0009] Further, the outer surface of the convex block is fixedly connected to the inner wall of the groove. A gear is fixedly connected to the outer surface of the connecting ring. A rack is meshed with the front surface of the gear. A sliding groove is formed in the inner wall of the rack. A fixing plate is slidably connected to the inner wall of the sliding groove. The front surface of the fixing plate is fixedly connected to the inner wall of the mounting groove. One end of the rack away from the fixing plate is fixedly connected with a connecting rod at the top. The outer surface of the connecting rod is in contact with the inner wall of the mounting groove. The top of the connecting rod penetrates through the workbench and extends to the outside. The fixing plate is used to limit the rack to prevent it from shifting when moving.

[0010] Further, the adjusting mechanism includes a sliding block fixedly connected to the top of the connecting rod. A sliding groove is formed inside the sliding block. A connecting rod is slidably connected to the inner wall of the sliding groove. The left side of the connecting rod penetrates through the sliding block and extends to the outside. A pull rod is fixedly connected to the left side of the connecting rod.

[0011] Further, an extrusion block is fixedly connected to the right side of the connecting rod. A second spring is sleeved on the outer surface of the connecting rod. The left side of the second spring is fixedly connected to the inner wall of the sliding groove. The right side of the second spring is fixedly connected to the left side of the extrusion block. The outer surface of the extrusion block is in contact with the inner wall of the sliding groove. The movement of the clamping rod is driven by the movement of the extrusion block.

[0012] Further, sliders are fixedly connected to both the front and back surfaces of the extrusion block. A clamping rod is in contact with both the front and back surfaces of the extrusion block. A T-shaped groove is formed at one end of the clamping rod close to the extrusion block. The outer surface of the slider is slidably connected to the inner wall of the T-shaped groove. A clamping rod is clamped at one end of the clamping rod away from the extrusion block. The right side of the clamping rod penetrates through the sliding block and extends to the outside. The right side of the clamping rod is fixedly connected to the left side of the bending groove. The left side of the bending groove is in contact with the right side of the sliding block. The clamping rod is moved closer to the inside by the cooperation of the slider and the T-shaped groove. At the same time, when the clamping rod moves closer to the inside, it will disengage from the clamping rod, and then the bending groove is taken out for replacement. The operation is simple and the replacement can be carried out quickly.

[0013] The utility model has the following beneficial effects:

[0014] By setting a friction ring in the present utility model, when not in use, the bending groove is located on the left side of the workbench, and there is a certain distance between the bending groove and the friction ring. When in use, the bending groove moves to the right, then pushes the pipe placed between the two to move, and clamps the pipe through the bending groove and the friction ring. Then, the pipe is bent by the rotation of the friction ring and the inclination angle of the bending groove. At the same time, pipes of different sizes can be used without manual fixing of the pipes.

[0015] By setting an extrusion block in the present utility model, when the pull rod is pulled to the left, the connecting rod moves when the pull rod moves to the left. The extrusion block moves by the movement of the connecting rod, and the clamping rod is pulled to move closer to the inside. Since the groove opened in the clamping rod is a T-shaped groove and the slider is also T-shaped, when the extrusion block moves to the left, the clamping rod will move closer to the inside through the cooperation of the slider and the T-shaped groove. At the same time, when the clamping rod moves closer to the inside, it will disengage from the clamping rod, and then the bending groove can be taken out for replacement. The operation is simple and the replacement can be carried out quickly.

[0028] A rotating table 115 is fixedly connected to the top of the rotating shaft 104. A friction ring 116 is fixedly connected to the outer surface of the rotating table 115. A connecting ring 105 is rotatably connected to the outer surface of the rotating shaft 104. An activity groove 111 is opened inside the connecting ring 105. There are two activity grooves 111 in total. The two activity grooves 111 are symmetrically arranged with the rotating shaft 104 as the center. When the bending groove 202 is not in use, it is located on the left side of the workbench 101, and there is a certain distance between the bending groove 202 and the friction ring 116. When in use, the bending groove 202 will move to the right, then push the pipe placed between the two to move, and clamp it through the bending groove 202 and the friction ring 116. Then, the pipe is bent through the rotation of the friction ring 116 and the inclination angle of the bending groove 202. At the same time, pipes of different sizes can be used.

[0029] The parts contained inside the two movable slots 111 are the same. A first spring 112 is fixedly connected inside the movable slot 111. A bump 113 is fixedly connected to the bottom of the first spring 112. A groove 114 is formed in the inner wall of the rotating shaft 104.

[0030] The outer surface of the bump 113 is fixedly connected to the inner wall of the groove 114. A gear 106 is fixedly connected to the outer surface of the connecting ring 105. A rack 108 is meshed with the front surface of the gear 106. A sliding groove 110 is formed in the inner wall of the rack 108.

[0031] A fixing plate 107 is slidably connected to the inner wall of the sliding groove 110. The front surface of the fixing plate 107 is fixedly connected to the inner wall of the mounting groove 102. A connecting rod 109 is fixedly connected to the top of the end of the rack 108 away from the fixing plate 107. The outer surface of the connecting rod 109 is in contact with the inner wall of the mounting groove 102. The top of the connecting rod 109 penetrates through the workbench 101 and extends to the outside.

[0032] The adjusting mechanism 2 includes a sliding block 201 fixedly connected to the top of the connecting rod 109. A sliding groove 205 is formed in the sliding block 201.

The left side of the second spring 206 is fixedly connected to the inner wall of the sliding groove 205. The right side of the second spring 206 is fixedly connected to the left side of the pressing block 208. The outer surface of the pressing block 208 is in contact with the inner wall of the sliding groove 205.

[0034] Sliders 210 are fixedly connected to both the front and back of the pressing block 208. A clamping rod 211 is in contact with both the front and back of the pressing block 208. A T-shaped groove 209 is formed at the end of the clamping rod 211 close to the pressing block 208. When the pull rod 203 is pulled to the left, when the pull rod 203 moves to the left, it drives the connecting rod 204 to move. By moving the connecting rod 204, the pressing block 208 is driven to move, and the clamping rod 211 is pulled to move closer to the inside. Since the groove formed in the clamping rod 211 is a T-shaped groove 209 and the slider 210 is also T-shaped, when the pressing block 208 moves to the left, the clamping rod 211 will be moved closer to the inside through the cooperation of the slider 210 and the T-shaped groove 209. At the same time, when the clamping rod 211 moves closer to the inside, it will disengage from the clamping rod 207, and then the bending groove 202 can be taken out for replacement. The operation is simple and can be quickly replaced.

[0035] The inner wall of the T-shaped groove 209 is slidably connected to the outer surface of the slider 210. One end of the clamping rod 211 away from the extrusion block 208 is clamped with a clamping rod 207. The right side of the clamping rod 207 penetrates through the sliding block 201 and extends to the outside. The right side of the clamping rod 207 is fixedly connected to the left side of the bending groove 202, and the left side of the bending groove 202 is in contact with the right side of the sliding block 201.

[0036] A specific application of this embodiment is as follows: First, the staff places the pipeline to the left of the friction ring 116, then starts the motor 103. When the motor 103 starts, it drives the rotating shaft 104 to rotate. Then, through the rotation of the rotating shaft 104, the rotating table 115 is driven to rotate. Through the rotation of the rotating table 115, the friction ring 116 is driven to rotate. When the rotating shaft 104 rotates, at this time, the convex block 113 is stuck in the groove 114, so the connecting ring 105 is driven to rotate simultaneously. Through the rotation of the connecting ring 105, the gear 106 is driven to rotate. The rack 108 rotates by the gear 106 and moves to the right. While the rack 108 moves to the right, it drives the connecting rod 109 to move to the right, and simultaneously drives the sliding block 201 and the bending groove 202 to move. When the bending groove 202 moves to the right, it will push the pipeline to the right until it contacts the friction ring 116. When the bending groove 202 cooperates with the friction ring 116 to clamp the conduit, the bending groove 202 will be stuck and unable to move. When the bending groove 202 is stuck, the rack 108 will also be stuck and unable to move. Therefore, the rack 108 will lock the gear 106. Since the convex block 113 and the groove 114 are both spherical and adapted to each other, and the rotating shaft 104 continues to rotate, the right convex block 113 will be extruded from the groove 114 and enter the movable groove 111. Therefore, the rotating shaft 104 can continue to rotate without being stuck. When not in use, the bending groove 202 is located on the left side of the workbench 101, and there is a certain distance between the bending groove 202 and the friction ring 116. When in use, the bending groove 202 will move to the right, then push the pipeline placed between the two to move, and clamp it through the bending groove 202 and the friction ring 116. Then, the pipeline is bent through the rotation of the friction ring 116 and the inclination angle of the bending groove 202. At the same time, pipelines of different sizes can be used. Sometimes different angles are required during bending. At this time, the bending groove 202 needs to be replaced. Pull the pull rod 203 to the left. When the pull rod 203 moves to the left, it drives the connecting rod 204 to move. Through the movement of the connecting rod 204, the extrusion block 208 is driven to move, and the clamping rod 211 is pulled closer to the inside. Since the groove opened in the clamping rod 211 is a T-shaped groove 209 and the slider 210 is also T-shaped, when the extrusion block 208 moves to the left, the clamping rod 211 will be pulled closer to the inside through the cooperation of the slider 210 and the T-shaped groove 209. At the same time, when the clamping rod 211 moves closer to the inside, it will disengage from the clamping rod 207. Then, the bending groove 202 can be taken out and replaced. The operation is simple and can be quickly replaced.
