Description

Technical Field

[0001] This invention relates to the field of control element pin bending technology, specifically a bending device for the production of power distribution switch control equipment components. Background Technology

[0002] As a core component in power systems for circuit switching, protection, and regulation, the pin processing precision of internal components directly determines the assembly stability and electrical performance of these devices. The pins of these components need to be bent at different angles, such as 45°, 90°, and 135°, depending on the PCB layout, installation space dimensions, and assembly scenario, to meet the requirements of dense wiring, avoidance of irregular structures, and reliable connections. Therefore, the pin bending process is a critical step in the production of power distribution switch components.

[0003] Traditional bending devices mostly use fixed-angle molds. If it is necessary to switch to other angles such as 45° or 135°, the corresponding molds must be disassembled and replaced manually. This is not only time-consuming and labor-intensive, but also prone to positioning deviations during mold disassembly and assembly, resulting in a decrease in the accuracy of subsequent bending angles. At the same time, some adjustable angle devices rely on manual knob adjustment, which cannot respond quickly according to the needs of component assembly and is difficult to meet the production scenarios of multiple varieties and small batches, thus restricting production efficiency.

[0019] The present invention provides a bending device for manufacturing components of power distribution switch control equipment, the advantages of which include:

[0020] 1. This invention, through the setting of the bending mechanism, can bend the pins at different angles to maximize the installation space and assembly requirements of electronic devices. In dense PCB boards, 90-degree vertical bending allows components to be mounted on the board, saving height space. In areas with irregular structures, 45-degree or 135-degree bending can avoid obstacles and prevent interference between components.

[0021] 2. This invention, through the setting of the bending angle adjustment mechanism, can adjust the bending angle of the pin according to the thickness of the pin. Thick pins have a strong springback effect, so the bending angle of the pin is automatically bent to less than 90 degrees. After springback, it can accurately fall to the preset value of 90 degrees. Thin pins have weak springback, so there is no need to make large adjustments to the bending angle to make the final angle meet the requirements, avoiding the uniform deviation of "thick pins having a larger angle and thin pins having a smaller angle".

[0022] 3. The present invention, through the setting of the transportation mechanism, can pre-smooth the pins of the component. Unsmoothed pins may have slight deformations at the factory. Direct bending will cause the bending point to be offset and the angle reference to be inconsistent. After smoothing, the pins are regular straight lines or fit the reference surface. When bending, they can be accurately aligned with the tool positioning point and reduce the angle deviation. If there are local wrinkles or stress concentration points on the pins, the external force will be applied to these weak points first when bending, causing the pin root or wrinkle to break. The smoothing process can disperse local stress, eliminate wrinkles, and make the force evenly distributed in the preset bending section when bending, which greatly reduces the risk of breakage.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figures 1-9This technical solution provides a bending device for the production of power distribution switch control equipment components, specifically including a platform 1. A bending mechanism 2 is installed inside the platform 1. The bending mechanism 2 includes a protective shell 201, which is fixedly installed on the top of the platform 1. An inner frame 202 is fixedly installed inside the protective shell 201. Two inner frames 202 are provided. A first sliding column 203 is slidably installed inside the front inner frame 202. A side pressure plate 204 is rotatably installed at the end of the first sliding column 203. A second torsion spring is installed inside the side pressure plate 204. An electric telescopic rod 205 is fixedly installed at the other end of the first sliding column 203. A second sliding column 206 is slidably installed on the rear inner frame. Inside the rear inner frame 202, a mounting plate 207 is fixedly installed at the end of the second sliding column 206. The mounting plate 207 is slidably installed inside the rear inner frame 202. The other end of the second sliding column 206 is connected to a bending angle adjustment mechanism 3, which can achieve different bending angles for pins of different thicknesses. A partition 208 is fixedly installed on the side of the rear inner frame 202. A slot 209 is opened on the surface of the partition 208. A bevel block 210 is fixedly installed at the bottom of the slot 209. A mounting base 211 is fixedly installed on the side of the mounting plate 207. A damping rod 212 is fixedly installed inside the mounting base 211. There are two damping rods 212. The surface of 212 is fitted with a first spring 213. A power pressure plate 214 is slidably mounted on the surface of the mounting plate 207. A pressure head 215 is fixedly mounted on the side of the power pressure plate 214. The inclined surface of the pressure head 215 has the same inclination angle as the inclined block 210. A guide rod 216 is fixedly mounted on the side of the mounting base 211. Two guide rods 216 are provided, and a second spring 217 is fitted on the surface of each guide rod 216. The second spring 217 is positioned between the mounting base 211 and the power pressure plate 214. When bending the pins of a component, if pins of the same thickness from the same batch are bent, because their thickness is the same, only the bending angle adjustment mechanism 3 will be activated. The second sliding column 206 reciprocates, and the stroke of the second sliding column 206 remains constant, thereby driving the mounting plate 207 to slide back and forth inside the rear inner frame 202. The mounting plate 207 drives the power pressure plate 214 to move back and forth, thereby bending the component pins that have moved into the slot 209. When bending pins of different thicknesses in the same batch, if the same bending angle is used, the thicker pins will spring back after bending due to their excessive yield strength. This will cause the pins that need to be bent at 90 degrees to be bent at 95 degrees in the end, resulting in quality problems in subsequent production processes.

[0036] Under the action of the bending angle adjustment mechanism 3, the sliding stroke of the second sliding column 206 will change, thus making the moving distance of the power pressure plate 214 longer. This causes the inclined surface of the pressure head 215 to come into contact with the surface of the inclined block 210. Under the action of the inclined block 210, the pressure head 215 will be displaced. Before the pressure head 215 contacts the inclined block 210, the pressure head 215 has already achieved the operation of bending the pin to 90 degrees. When the pressure head 215 contacts the inclined block 210, the pressure head 215 will be displaced, causing the bending angle of the pin to change again. The bending angle of the pin is less than 90 degrees, which can offset the influence of the yield strength caused by the thicker pin.

[0037] This structure can also be used to bend lead elements of the same thickness at different angles. The thickness detection part in the bending angle adjustment mechanism 3 is disassembled and directly connected to a hydraulic telescopic rod. Different lead angles are achieved by controlling the stroke of the telescopic rod. The electric telescopic rod 205 drives the side pressure plate 204 to move. When the pressure head 215 bends the lead to less than 90 degrees, the electric telescopic rod 205 drives the side pressure plate 204 to move. The side pressure plate 204 rotates due to the lead during the movement, allowing it to be smoothly pulled out from the bent lead. Then, it returns to its original position under the action of the second torsion spring. The electric telescopic rod 205 then moves the side pressure plate 204 towards the pressure head 215 again to perform a second bending of the bent lead. The bending angle of 90 degrees to 180 degrees is achieved by controlling the moving distance of the pressure head 215.

[0038] Reference Figures 1-9This embodiment also proposes a bending angle adjustment mechanism 3, including a first motor 301, which is fixedly mounted on the top of the platform 1. A first mounting bracket 302 is fixedly mounted on the top of the platform 1. A crankshaft 303 is rotatably mounted inside the first mounting bracket 302. A first rotating shaft 304 is rotatably mounted on the side of the first mounting bracket 302. The first rotating shaft 304 is fixedly connected to the crankshaft 303. The output end of the first motor 301 is fixedly connected to the first rotating shaft 304. A second mounting bracket 305 is fixedly mounted on the top of the platform 1. A second rotating shaft 306 is rotatably mounted inside the mounting bracket 305. A connecting assembly 307 is fixedly mounted at the end of the second rotating shaft 306. A connecting seat 308 is rotatably mounted at the eccentric part of the crankshaft 303. A first connecting plate 309 is rotatably mounted at one end of the connecting seat 308. The end of the first connecting plate 309 is rotatably connected to the second sliding column 206. An eccentric circular plate 310 is eccentrically fixedly mounted at the other end of the second rotating shaft 306. A second connecting plate 311 is rotatably mounted on the surface of the eccentric circular plate 310. The end of the second connecting plate 311 is connected to the connecting seat 305. 8. Rotary connection: The connecting assembly 307 includes a mounting plate 3071, which is fixedly mounted on the surface of the second rotating shaft 306. A first torsion spring 3072 is sleeved on the surface of the second rotating shaft 306 and is disposed between the mounting plate 3071 and the second mounting bracket 305. The first motor 301 can drive the first rotating shaft 304 to rotate, which in turn drives the crankshaft 303 to rotate. The rotation of the crankshaft 303 can drive the connecting seat 308 to rotate, thereby driving the first connecting plate 3... 09 performs an eccentric rotation, which drives the second sliding column 206 to reciprocate within the rear inner frame 202. When the second rotating shaft 306 rotates, it drives the eccentric circular plate 310 to rotate. The rotation of the eccentric circular plate 310 drives the second connecting plate 311 to rotate eccentrically, which causes the connecting seat 308 to rotate within the crankshaft 303. The rotation of the connecting seat 308 causes a change in the eccentric torque of the first connecting plate 309, which in turn changes the reciprocating sliding stroke of the second sliding column 206.

[0039] Reference Figures 1-9This embodiment also proposes that a first gear 3073 is rotatably mounted on the side of the mounting plate 3071. The first gear 3073 has a ratchet groove 3074 inside, and multiple ratchet grooves 3074 are provided. A connecting block 3075 is fixedly mounted on the side of the mounting plate 3071. A ratchet pawl 3076 is rotatably mounted on the surface of the connecting block 3075, and multiple ratchet pawls 3076 are provided. These ratchet pawls mesh with the ratchet grooves 3074. A third spring 3077 is provided between the ratchet pawl 3076 and the connecting block 3075. An electromagnetic component 3078 is provided inside the third spring 3077. The electromagnetic component 3078 includes an electromagnet and a metal block. When the electromagnetic component 3078 is energized, the ratchet pawl 3076 rotates on the surface of the connecting block 3075. The ratchet pawl 3076 no longer meshes with the ratchet groove 3074. The rotation of the first gear 3073 will not affect the rotation of the connecting block 3075. The connecting block 3075 and the mounting plate 3071 will rotate back to their original positions under the action of the first torsion spring 3072. When the electromagnetic component 3078 is de-energized, the ratchet pawl 3076 meshes with the ratchet groove 3074. When the first gear 3073 rotates counterclockwise, the connecting block 3075 will not drive the second rotating shaft 306 to rotate. However, when the first gear 3073 rotates clockwise, the first gear 3073 can drive the second rotating shaft 306 to rotate, and at the same time, the first torsion spring 3072 will generate elastic potential energy. Once the electromagnetic component 3078 is energized, the elastic potential energy generated by the first torsion spring 3072 will cause the second rotating shaft 306 to rotate to its initial state.

[0040] Reference Figures 1-9This embodiment also proposes that a transport mechanism 4 be provided on the top of the platform 1. The transport mechanism 4 includes a control console 401, which integrates a control board and a signal processor. The control console 401 is fixedly installed on the top of the platform 1. A cylinder 402 is fixedly installed on the top of the platform 1. A clamping frame 403 is fixedly installed on the output end of the cylinder 402. A clamping claw 404 is slidably installed inside the clamping frame 403 via a pneumatic guide rail. Two clamping claws 404 are provided. A transport guide rail 405 is fixedly installed on the top of the platform 1. A control element 406 is placed inside the transport guide rail 405. The control console 401 can control the cylinder 402 and the pneumatic guide rail. The cylinder 402 can push the clamping frame 403 to move. When the cylinder 402 pushes the clamping frame 403... When the gripper 404 moves to the top of the control element 406, the two grippers 404 are brought closer together by the pneumatic guide rail to clamp the control element 406. The cylinder 402 is fixedly mounted on the top of the platform 1 by bolts. The operator can adjust the bending position of the pin by changing the height of the cylinder 402 to accommodate pins of different lengths. The top of the transport guide rail 405 is fixedly mounted with a clamping plate 407 by bolts. There are two clamping plates 407. The clamping plates 407 can straighten the top of the control element 406 and prevent the control element 406 from tilting. The top of each clamping plate 407 is rotatably mounted with a second gear 408, and the bottom of each clamping plate 407 is rotatably mounted with a threaded rod 409. The threaded rod 409 is fixedly connected to the second gear 408. A base plate 410 is fixedly installed on the bottom of each of the two clamping plates 407. A mounting frame 411 is slidably installed on the side of the base plate 410. A roller 412 is rotatably installed inside the mounting frame 411. A threaded cylinder 413 is fixedly installed on the top of the mounting frame 411, and the threaded cylinder 413 is threadedly connected to the threaded rod 409. A first toothed plate 414 is slidably installed on the top of the clamping plate 407, and the first toothed plate 414 meshes with the second gear 408. A sliding cylinder 415 is fixedly installed on the side of the first toothed plate 414, and a sliding rod 416 is slidably installed inside the sliding cylinder 415. The sliding rod 416 is fixedly connected to the clamping jaw 404. When the clamping jaw 404 moves, it can drive the first toothed plate 414. The movement of the platform 1 drives the second gear 408 to rotate, which in turn drives the threaded rod 409 to rotate, thereby causing the mounting frame 411 to move up and down. This, in turn, causes the roller 412 to move up and down, smoothing out irregular pins. A second electric slide rail 417 is fixedly installed on the top of the platform 1. A sliding block 418 is slidably installed inside the second electric slide rail 417. A stop bar 419 is fixedly installed on the side of the sliding block 418. A laser emitter 420 is fixedly installed on the surface of the stop bar 419. A laser receiver 421 is fixedly installed on the side of the control console 401. When the laser receiver 421 receives the laser emitted by the laser emitter 420,The control console 401 controls the second electric slide rail 417 to move the stop lever 419 to the front of the transport guide rail 405, blocking the control element 406 and preventing it from falling out of the transport guide rail 405. When the control element 406 moves to the front of the stop lever 419, it blocks the laser emitted by the laser emitter 420. At this time, the gripper 404, controlled by the control console 401, grips the control element 406. Simultaneously, the laser receiver 421 no longer receives the laser emitted by the laser receiver 421, the stop lever 419 returns to its original position, no longer blocking the control element 406, and the gripper 404 moves, further moving the control element 406. After the clamping movement and the control element 406 leaves its original position, the laser receiver 421 receives the laser emitted by the laser emitter 420 again. The stop bar 419 moves again to block the subsequent control element 406. A sliding groove 422 is fixedly installed on the side of the second electric slide rail 417. A second toothed plate 423 is slidably installed inside the sliding groove 422. A top seat 424 is fixedly installed on the top of the platform 1. A thickness measuring plate 425 is slidably installed inside the top seat 424. There are two thickness measuring plates 425. A side rod 426 is fixedly installed on the side of each thickness measuring plate 425. A fourth spring 427 is sleeved on the surface of the side rod 426. The side rod 426 passes through the side of the top seat 424 and is slidably connected to the top seat 424. The right side rod 426... A connecting vertical plate 428 is fixedly connected to the second toothed plate 423. The second toothed plate 423 meshes with the first gear 3073. The thickness measuring plate 425 can measure the thickness of the pin. This structure can be installed when producing pins of different thicknesses in the same batch. However, when producing pins of the same thickness, it can be removed and replaced with a separate hydraulic telescopic rod for adjustment. The separate hydraulic telescopic rod is directly connected to the second sliding column 206, and the hydraulic telescopic rod directly controls the second sliding column 206. When the pin enters between the two thickness measuring plates 425, the two thickness measuring plates 425 move, driving the second toothed plate 423 to move, thereby enabling the first gear 3073 to move. When the pin rotates clockwise, the rotation of the first gear 3073 drives the second rotating shaft 306 to rotate. After the pin passes the positions of the two thickness measuring plates 425, the thickness measuring plates 425 return to their original positions. When the first gear 3073 rotates counterclockwise, the second rotating shaft 306 does not follow the rotation of the first gear 3073 and remains in its original position. However, the ratchet pawl 3076 remains engaged with the ratchet groove 3074. Under the action of the first gear 3073, the second rotating shaft 306 will not return to its original position. When the clamping pawl 404 clamps again, the control console 401 controls the electromagnetic component 3078 to energize it, causing the ratchet pawl 3076 to disengage from the ratchet groove 3074.The second rotating shaft 306 returns to its original position under the action of the first torsion spring 3072, ready for the subsequent control element 406 to pass between the thickness measuring plates 425.

[0041] Specifically, the working process or working principle of the bending device for producing components of a power distribution switch control equipment is as follows: When bending the pins of the components, if pins of the same thickness in the same batch are bent, because their pin thickness is the same, the bending angle adjustment mechanism 3 drives the second sliding column 206 to reciprocate, and the stroke of the second sliding column 206 remains unchanged, thereby driving the mounting plate 207 to slide back and forth inside the rear inner frame 202. The mounting plate 207 drives the power pressure plate 214 to move back and forth, thereby bending the component pins that have moved into the slot 209. When bending pins of different thicknesses in the same batch, if the same bending angle is used, the thicker pins will spring back after bending due to their excessive yield strength. This will cause the pins that need to be bent at 90 degrees to be bent at 95 degrees in the end, resulting in quality problems in subsequent production processes.

[0042] Under the action of the bending angle adjustment mechanism 3, the sliding stroke of the second sliding column 206 will change, thus making the moving distance of the power pressure plate 214 longer. This causes the inclined surface of the pressure head 215 to come into contact with the surface of the inclined block 210. Under the action of the inclined block 210, the pressure head 215 will be displaced. Before the pressure head 215 contacts the inclined block 210, the pressure head 215 has already achieved the operation of bending the pin to 90 degrees. When the pressure head 215 contacts the inclined block 210, the pressure head 215 will be displaced, causing the bending angle of the pin to change again. The bending angle of the pin is less than 90 degrees, which can offset the influence of the yield strength caused by the thicker pin.

[0043] This structure can also be used to bend lead elements of the same thickness at different angles. The thickness detection part in the bending angle adjustment mechanism 3 is disassembled and directly connected to a hydraulic telescopic rod. Different lead angles are achieved by controlling the stroke of the telescopic rod. The electric telescopic rod 205 drives the side pressure plate 204 to move. When the pressure head 215 bends the lead to less than 90 degrees, the electric telescopic rod 205 drives the side pressure plate 204 to move. The side pressure plate 204 rotates due to the lead during the movement, allowing it to be smoothly pulled out from the bent lead. Then, it returns to its original position under the action of the second torsion spring. The electric telescopic rod 205 then moves the side pressure plate 204 towards the pressure head 215 again to perform a second bending of the bent lead. The bending angle of 90 degrees to 180 degrees is achieved by controlling the moving distance of the pressure head 215.

[0044] The first motor 301 can drive the first rotating shaft 304 to rotate. The rotation of the first rotating shaft 304 can drive the crankshaft 303 to rotate. The rotation of the crankshaft 303 can drive the connecting seat 308 to rotate, which in turn can drive the first connecting plate 309 to rotate eccentrically. This can drive the second sliding column 206 to rotate back and forth inside the rear inner frame 202. When the second rotating shaft 306 rotates, it can drive the eccentric circular plate 310 to rotate. The rotation of the eccentric circular plate 310 can drive the second connecting plate 311 to rotate eccentrically. This can cause the connecting seat 308 to rotate inside the crankshaft 303. The rotation of the connecting seat 308 causes the eccentric torque of the first connecting plate 309 to change, thereby changing the reciprocating sliding stroke of the second sliding column 206.

[0045] The electromagnetic component 3078 includes an electromagnet and a metal block. When the electromagnetic component 3078 is energized, the ratchet pawl 3076 rotates on the surface of the connecting block 3075, and the ratchet pawl 3076 no longer meshes with the ratchet groove 3074. The rotation of the first gear 3073 does not affect the rotation of the connecting block 3075, while the connecting block 3075 and the mounting plate 3071 will rotate back to their original positions under the action of the first torsion spring 3072. When the electromagnetic component 3078 is de-energized, the ratchet pawl 3076... 076 meshes with ratchet groove 3074. When the first gear 3073 rotates counterclockwise, the connecting block 3075 will not drive the second rotating shaft 306 to rotate. However, when the first gear 3073 rotates clockwise, it can drive the second rotating shaft 306 to rotate, and at the same time, the first torsion spring 3072 will generate elastic potential energy. Once the electromagnetic component 3078 is energized, the elastic potential energy generated by the first torsion spring 3072 will cause the second rotating shaft 306 to rotate to its initial state.

[0046] The control console 401 can control the cylinder 402 and the pneumatic guide rail. The cylinder 402 can push the clamping frame 403 to move. When the cylinder 402 pushes the clamping claw 404 to move to the top of the control element 406, the two clamping claws 404 are brought closer together by the pneumatic guide rail to clamp the control element 406. The cylinder 402 is fixedly installed on the top of the platform 1 by bolts. The operator can adjust the bending position of the pin by changing the height of the cylinder 402 to accommodate pins of different lengths. When the clamping claw 404 moves, it can drive the first toothed plate 414 to move, which in turn drives the second gear 408 to rotate. The rotation of the second gear 408 can drive the threaded rod 409 to rotate, which in turn drives the mounting frame 411 to move up and down, which in turn causes the roller 412 to move up and down. The up and down movement of the roller 412 can smooth out irregular pins.

[0047] When the laser receiver 421 receives the laser emitted by the laser emitter 420, the control console 401 controls the second electric slide rail 417 to move the stop lever 419. The stop lever 419 moves to the front of the transport guide rail 405, blocking the control element 406 and preventing it from falling out of the transport guide rail 405. When the control element 406 moves to the front of the stop lever 419, it blocks the laser emitted by the laser emitter 420. At this time, the gripper 404... The control console 401 controls the control element 406 to clamp it. At the same time, the laser receiver 421 no longer receives the laser emitted by the laser receiver 421, the stop lever 419 returns to its original position and no longer blocks the control element 406. Meanwhile, the clamping claw 404 moves to clamp and move the control element 406. After the control element 406 leaves its original position, the laser receiver 421 receives the laser emitted by the laser emitter 420 again, and the stop lever 419 moves again to block the subsequent control element 406.

[0048] The second toothed plate 423 meshes with the first gear 3073. The thickness measuring plate 425 can measure the thickness of the pin. This structure can be installed when producing pins of different thicknesses in the same batch. However, when producing pins of the same thickness, it can be removed and replaced with a separate hydraulic telescopic rod for adjustment. When the pin enters between the two thickness measuring plates 425, the two plates move, causing the second toothed plate 423 to move, which in turn causes the first gear 3073 to rotate clockwise. The rotation of the first gear 3073 then drives the second rotating shaft 306 to rotate. After the pin passes the positions of the two thickness measuring plates 425, the thickness measuring plate... 425 returns to its original position, the first gear 3073 rotates counterclockwise, the second rotating shaft 306 does not follow the first gear 3073 and remains in its original position, but the ratchet pawl 3076 is still engaged with the ratchet groove 3074. Under the action of the first gear 3073, the second rotating shaft 306 will not return to its original position. When the clamping pawl 404 clamps again, the control console 401 controls the electromagnetic component 3078 to energize it, causing the ratchet pawl 3076 to separate from the ratchet groove 3074. The second rotating shaft 306 returns to its original position under the action of the first torsion spring 3072, ready for the subsequent control element 406 to pass between the thickness measuring plates 425.
