Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a parts processing device and its processing method. Background Technology

[0002] This invention relates to the field of metal parts stamping technology, specifically to a metal parts loading and unloading device for automated stamping production lines, particularly suitable for batch stamping of small and medium-sized metal parts (such as stamped gaskets, small brackets, connector housings, etc.) in automotive parts, electronic components, and general mechanical parts. In modern manufacturing, with the accelerating pace of production and increasing requirements for processing precision, enterprises have increasingly prominent needs for continuous operation capabilities, precise part positioning, and unmanned operation of stamping production lines—achieving full-process coordination from automatic sorting and loading of metal parts, precise delivery to the stamping station, to automatic unloading after stamping, in order to reduce manual intervention, lower scrap rates caused by manual operation, and ensure the stability and economy of the batch production process, meeting the high-efficiency and high-precision processing requirements of industrial production lines.

[0003] In real-world industrial scenarios, existing technologies for loading and unloading metal parts in stamping mainly fall into two categories: one is "semi-automatic feeding + rigid fixing" equipment for small to medium batch production. Its typical structure consists of a vibratory feeder combined with a pneumatic clamping mechanism. The vibratory feeder sorts the disordered parts through vibration, then transports them to the receiving plate via a straight discharge track. Independent pneumatic grippers clamp the parts at the receiving plate to fix them in place, and then the parts are transferred to the stamping station via a conveyor belt. The other category is "modular handling + program control" equipment for mass production. For example, a rotary tray is used to store parts. A servo-driven lateral movement module works in conjunction with a lifting and gripping mechanism to grab the parts from the tray to the stamping worktable. The positioning of the parts depends on the mechanical stops preset on the worktable.

[0004] However, due to the lack of an adaptive adjustment structure that is linked to the motion state of the conveying mechanism, the parts are easily loosened by the vibration of the conveying or the impact of the stamping. This not only leads to a decrease in the stamping accuracy (such as excessive deviation of part dimensions and excessive edge burrs), but also requires frequent manual stops to adjust the position of the parts, which reduces the automation level and continuous operation efficiency of the production line. Summary of the Invention

[0005] The purpose of this invention is to provide a parts processing device and a processing method thereof, which aims to improve the problem of parts being easily loosened by conveying vibration or stamping impact in the prior art.

As a further description of the above technical solution: The tension adjusting component includes a support shaft, which is fixedly connected to the rear end of the driven roller. Limiting posts are provided on both sides of the stamping forming device. Limiting grooves are opened inside the limiting posts. An arc-shaped track is fixedly connected to the top of the limiting posts. A sliding groove is opened inside the arc-shaped track. A fixed shaft is fixedly connected to the outside of the support shaft. A rotating sleeve is rotatably connected to the outside of the support shaft, and the outside of the rotating sleeve is slidably connected inside the sliding groove.

As a further description of the above technical solution: The driving component includes an output shaft fixedly connected to the rear end of the drive roller, a movable groove is provided at the front end of the stamping forming device, the outer side of the output shaft is slidably connected to the inside of the movable groove, a motor is installed inside the stamping forming device, and the motor can slide inside the stamping forming device, the output end of the motor is connected to the output shaft, an extension shaft is fixedly connected to the outer side of the output shaft, a buffer damping cylinder is fixedly connected to the outer side of the stamping forming device, and the bottom end of the extension shaft is slidably connected to the inside of the buffer damping cylinder. As a further description of the above technical solution: The stamping forming device includes a support platform, a controller is provided on the top of the support platform, a stamping head is provided at the output end of the controller, and a worktable is provided at the front end of the support platform. As a further description of the above technical solution: The top of the base is provided with a feeding device and a discharging robot. The feeding device includes a support frame, and a vibrating feeder is provided on the top of the support frame. A discharge track is provided on the outside of the vibrating feeder. A metal spring is provided on the inner side of the end of the discharge track to prevent metal parts from falling. An electromagnet is provided on the gripping end of the discharging robot. A method for processing parts, applicable to any of the parts processing apparatuses described above, comprising the following steps: S1. Equipment Start-up: Start the two motors corresponding to the conveyor belt to make the conveyor belt start to rotate; at the same time, start the vibrating feeder and the punch head. The metal parts enter the discharge track through the vibrating feeder and are stuck by the metal springs in the track, preparing for subsequent feeding and processing. At this time, all equipment is in the initial working state, waiting for the subsequent processing action to be triggered, ensuring that the initial position and running state of each component before linkage are normal. S2. Pressure Adjustment: The punch head presses downwards, transmitting force to the receiving plate. The receiving plate then presses down the middle section of the conveyor belt, causing the two driven rollers to tilt upwards. Simultaneously, the tension of the conveyor belt drives the two driving rollers upwards. When the driven rollers tilt upwards, they are restricted by the limiting posts. The support shaft slides along the limiting groove on the arc track and compresses the buffer spring. The output shaft of the driving roller slides in the movable groove and is acted upon by the buffer damping cylinder, ensuring stable deformation and constant tension of the conveyor belt and preventing damage to the belt due to pressure. S3. Feeding Plate: The driven roller tilts up, causing the corresponding receiving plate to tilt up synchronously. After one end of the receiving plate in the feeding direction tilts up, the clamping post and the counterweight block, under the action of gravity, overcome the tension of the tension spring and the magnetic force of the first magnetic block and slide outwards towards the receiving plate. After the counterweight block slides, the sealing block loses its squeezing force and slides and separates into the receiving plate under the attraction of the second magnetic block, opening the feeding channel; at the same time, the driven roller tilts up and moves the components on the discharge track, causing them to overcome the elastic force of the metal spring sheet and enter the feeding channel, finally falling into the middle of the receiving plate under gravity; S4. Reset Fixture: The stamping head moves upward, the tension adjusting component and the drive component reset synchronously, the conveyor belt returns to its normal shape, and the receiving plate returns to a horizontal state. The elastic force of the tension spring causes the clamping pile to retract inward, pressing against the outside of the metal parts; the attraction of the magnetic block one causes the counterweight block to move towards the receiving plate, and the wedge-shaped surfaces at both ends of the counterweight block squeeze the sealing block, causing the two sealing blocks to close together, completing the fixation of the metal parts inside the receiving plate, preparing for subsequent stamping; S5. Stamping and Blanking: The conveyor belt moves the fixed metal parts, transporting them directly below the stamping head. The stamping head is activated, pressing down to stamp the parts. After stamping, the unloading robot is activated, using electromagnets on the robot to attract the formed parts and remove them from the receiving plate, thus completing the unloading process. This achieves the complete automatic feeding, stamping, and unloading of metal parts, while maintaining stable conveyor belt tension throughout the process.

[0007] Compared with the prior art, the advantages of the present invention are as follows: 1. By tilting the driven roller, the receiving plate is tilted synchronously. The tilting of the receiving plate causes the clamping pile and the counterweight to slide under the action of gravity, overcoming the tension of the tension spring and the magnetic force of the magnetic block one. The sliding of the counterweight releases the squeezing force on the sealing block. The sealing block separates under the attraction of the magnetic block two, opening the feeding channel. At the same time, the tilting of the driven roller pushes the metal parts on the discharge track to overcome the elastic force of the metal spring and enter the feeding channel. When the stamping head resets, the tension adjustment component and the drive component reset, driving the receiving plate to be horizontal. The tension spring and the magnetic block one drive the counterweight to reset. The wedge-shaped surface of the counterweight squeezes the sealing block to close and fix the parts. This realizes the automatic and precise feeding and stable fixing of metal parts, providing a reliable guarantee for subsequent stamping and forming and robotic unloading, and improving the automation level and processing accuracy of the overall stamping production.

[0008] 2. The pressing head drives the receiving plate downwards, which in turn drives the middle part of the conveyor belt downwards, causing the driven roller to tilt upwards and the driving roller to move upwards. When the driven roller tilts upwards, the support shaft slides along the arc track under the restriction of the limit stake and the limit groove, and squeezes the buffer spring. When the driving roller moves upwards, the output shaft slides in the movable groove and is damped by the buffer damping cylinder. This ultimately achieves stable deformation of the conveyor belt and ensures that the conveyor belt maintains stable tension when the pressing head is pressed down. This effectively avoids damage to the conveyor belt caused by a sudden increase in tension due to pressure, thus ensuring the service life and operational reliability of the conveyor belt.

The feeding device 4 includes a support frame 401, which is used to support the vibrating feeder 402 to ensure the stable installation of the vibrating feeder 402. The vibrating feeder 402 is provided on the top of the support frame 401. The vibrating feeder 402 vibrates... The metal parts 6 are sorted so that they enter the discharge track 403 in a preset direction. The discharge track 403 is provided on the outside of the vibrating feeder 402. The discharge track 403 provides a conveying channel for the metal parts 6 and limits the conveying path of the parts. The inner side of the end of the discharge track 403 is provided with a metal spring 404 to prevent the metal parts 6 from falling. The metal spring 404 controls the feeding rhythm of the parts and prevents the parts from slipping out prematurely. The gripping end of the unloading robot 5 is provided with an electromagnet. The electromagnet attracts the parts by magnetic force to ensure a stable gripping process.

[0013] The stamping forming device 2 includes a support platform 201, which provides mounting support for the controller 202, the stamping head 203, and the worktable 204 to ensure stable stamping operation. The controller 202 is installed on the top of the support platform 201. The controller 202 is used to control the start, stop, and movement of the stamping head 203 and coordinate the linkage of various components. The stamping head 203 is installed at the output end of the controller 202. The stamping head 203 stamps and forms parts by pressing down, thereby realizing the shape processing of the parts. The worktable 204 is installed at the front end of the support platform 201. The worktable 204 provides an operating platform for the conveying device 3 and the receiving structure to ensure that the parts are in a stable processing position.

[0014] The base 1 is also equipped with a receiving plate 361 on its top. The receiving plate 361 is used to receive metal parts 6 and provide space for the parts. A spring is provided at its bottom to buffer the pressure on the receiving plate 361 and keep the receiving plate 361 moving stably. A clamping post 362 is provided on the top of the receiving plate 361. The clamping post 362 is used to clamp the outside of the metal parts 6 to prevent the parts from shifting during conveying or stamping. A counterweight 364 is provided on the top of the clamping post 362. The counterweight 364 assists in adjusting the position of the clamping post 362 through gravity and drives the clamping post 362 to slide. A tension spring 363 is provided on one side of the clamping post 362. 63 provides a reset spring force for the clamping pile 362, causing the clamping pile 362 to retract inward. A magnetic block 365 is provided on the other side of the clamping pile 362. The magnetic block 365 attracts the counterweight 364 through magnetic force, assisting the counterweight 364 to reset towards the receiving plate 361. A sealing block 366 is provided at the bottom of the clamping pile 362. The sealing block 366 is used to control the opening and closing of the feeding channel. When it is open, it allows parts to enter. When it is closed, it fixes the parts. A magnetic block 367 is provided at the bottom of the sealing block 366. The magnetic block 367 drives the sealing block 366 to slide into the receiving plate 361 through attraction, so that the sealing block 366 separates to open the feeding channel.

[0015] The conveying device 3 includes two driving rollers 31 and two driven rollers 33. Driven rollers 33 are mounted on the top of the base 1, and work in conjunction with the driving rollers 31 to support the conveyor belt 35, adjust the tension of the conveyor belt 35, and prevent slack. A motor 323 is mounted on the top of the driven rollers 33, providing rotational power. The output shaft 321 of the motor 323 is connected to the input end of the driven rollers 33 via a coupling. The coupling is used to stably transmit the power of the motor 323, ensuring synchronous rotation of the driven rollers 33. A controller 202 is mounted on one side of the motor 323, controlling the start, stop, and speed of the motor 323, and coordinating the operation of the motor 323 with other components. The output end of the controller 202 is electrically connected to the input end of the motor 323. The controller 202 is electrically connected to the output of the control box, enabling the control box to transmit commands to the motor 323. A conveyor belt 35 is coupled to the outer sides of the two active rollers 31 and the two driven rollers 33. The conveyor belt 35 rotates to move the components, thus transferring the components to their workstations. A drive unit 32 is located at the rear end of the active rollers 31, providing rotational power and assisting in adjusting the position of the active rollers 31 to stabilize the belt tension. A tension adjusting unit 34 is located at the rear end of the driven rollers 33, compensating for belt slack or deformation to ensure the belt maintains stable tension. A receiving unit 36 ​​is engaged on the outer side of the conveyor belt 35, fixing the position of the components and moving synchronously with the belt.

[0016] The driving component 32 includes an output shaft 321 fixedly connected to the rear end of the drive roller 31. The output shaft 321 connects the drive roller 31 and the motor 323, transmitting power from the motor 323 to drive the drive roller 31 to rotate. It can also slide within a movable groove 322 to adjust the position of the drive roller 31. A movable groove 322 is provided at the front end of the stamping forming device 2, providing sliding space for the output shaft 321, allowing it to move up and down with the drive roller 31. The outer side of the output shaft 321 is slidably connected to the inside of the movable groove 322. A motor 323 is installed inside the stamping forming device 2, and the motor 323 can move within the stamping forming device. The internal sliding of the device 2 is coordinated with the output shaft 321 to adjust its position. The output end of the motor 323 is connected to the output shaft 321, and the motor 323 provides rotational power to the output shaft 321. An extension shaft 324 is fixedly connected to the outside of the output shaft 321. The extension shaft 324 is used to connect the output shaft 321 and the buffer damping cylinder 325 to transmit the movement of the output shaft 321. The buffer damping cylinder 325 is fixedly connected to the outside of the stamping forming device 2. The buffer damping cylinder 325 slows down the sliding speed of the extension shaft 324 through internal damping, keeping the movement of the drive roller 31 stable. The bottom end of the extension shaft 324 is slidably connected inside the buffer damping cylinder 325.

[0017] The tension adjusting component 34 includes a support shaft 341, which connects the driven roller 33 and the rotating sleeve 343, driving the driven roller 33 to adjust its position to regulate the chain tension. The support shaft 341 is fixedly connected to the rear end of the driven roller 33. Limiting posts 344 are provided on both sides of the stamping forming device 2. The limiting posts 344 are used to fix the limiting groove 345 and the arc-shaped track 346, limiting the movement range of the driven roller 33. The limiting post 344 has a limiting groove 345 inside, which limits the movement trajectory of the support shaft 341, ensuring that the driven roller 33 moves in a preset direction. The top of the limiting post 344 is fixedly connected to the arc-shaped track 346, which provides a sliding path for the rotating sleeve 343, guiding the driven roller 33 to adjust its position along the arc-shaped trajectory. The arc-shaped track 346 has a sliding groove 347 inside. 7 provides sliding space for the rotating sleeve 343, allowing the rotating sleeve 343 to move along the arc-shaped track 346. The outer side of the support shaft 341 is fixedly connected to the fixed shaft 342, which is used to stabilize the connection between the support shaft 341 and the rotating sleeve 343 and prevent them from separating. The outer side of the support shaft 341 is rotatably connected to the rotating sleeve 343, and the outer side of the rotating sleeve 343 is slidably connected inside the sliding groove 347. The rotating sleeve 343 is used to transmit the reaction force of the buffer spring 348 to the support shaft 341 and adjust the position of the driven roller 33. The inner side of the arc-shaped track 346 is fixedly connected to the buffer spring 348, and the other end of the buffer spring 348 is connected to the outer side of the rotating sleeve 343. The buffer spring 348 generates a reaction force through elastic deformation, which slows down the movement speed of the driven roller 33, keeps the movement of the driven roller 33 stable, and compensates for the slack of the chain belt.

[0018] The receiving component 36 includes a receiving plate 361. The bottom ends of the receiving plate 361 are engaged with the outer sides of two conveyor belts 35 and move synchronously with the conveyor belts 35. The receiving plate 361 is slidably connected with a retaining post 362. A tension spring 363 is provided between the retaining post 362 and the outer side of the receiving plate 361. A counterweight 364 is slidably connected to the outer side of the retaining post 362 and the inside of the receiving plate 361. A magnetic block 365 is provided on the inner side of the counterweight 364 and the opposite side of the receiving plate 361. Two sealing blocks 366 are slidably connected in the middle of the receiving plate 361. The two ends of the counterweight 364 are set as wedge-shaped surfaces. The wedge-shaped surfaces are controlled by the counterweight 364 sliding to squeeze or release the sealing blocks 366, thus controlling the opening and closing of the sealing blocks 366. The shape of one end of the two sealing blocks 366 sliding inside the receiving plate 361 is adapted to and abuts the wedge-shaped surfaces at both ends of the counterweight 364. One outer end of the sealing block 366 is provided with an arc-shaped guide surface, which is used to guide the component smoothly into the middle of the receiving plate 361 to avoid feeding jamming. Furthermore, the inner shape of the two sealing blocks 366 after they are closed and the two end shapes of the clamping post 362 are adapted to the outer shape of the metal component 6, ensuring that the component is firmly fixed. Additionally, the receiving plate 361 has a magnetic suction block 367 inside that attracts the rear end of the sealing block 366.

[0019] A method for processing parts, applicable to the aforementioned part processing apparatus, comprising the following steps: S1. Equipment Start-up: Start the two motors 323 corresponding to the conveyor belt 35 to make the conveyor belt 35 start to rotate; at the same time, start the vibratory feeder and the stamping head 203. The metal parts 6 enter the discharge track 403 through the vibratory feeder and are stuck by the metal spring 404 in the track, preparing for subsequent feeding and processing. At this time, all equipment is in the initial working state, waiting for the subsequent processing action to be triggered, ensuring that the initial position and running state of each component before linkage are normal. S2. Pressure Adjustment: The punch head 203 presses downward, and the force is transmitted to the receiving plate 361. The receiving plate 361 drives the middle part of the conveyor belt 35 to press down, which in turn drives the two driven rollers 33 to tilt up. At the same time, the tension of the conveyor belt 35 drives the two driving rollers 31 to move upward. When the driven rollers 33 tilt up, they are restricted by the limiting post 344. The support shaft 341 slides along the limiting groove 345 on the arc track 346 and squeezes the buffer spring 348. The output shaft 321 of the driving roller 31 slides in the movable groove 322 and is affected by the buffer damping cylinder 325, ensuring that the deformation of the conveyor belt 35 is stable and the tension is constant, and avoiding damage to the belt due to pressure. S3. Feeding Plate: The driven roller 33 tilts up, causing the corresponding receiving plate 361 to tilt up synchronously. After one end of the receiving plate 361 tilts up in the feeding direction, the clamping pile 362 and the counterweight block 364, under the action of gravity, overcome the tension of the tension spring 363 and the magnetic force of the magnetic block 365 and slide to the outside of the receiving plate 361. After the counterweight block 364 slides, the sealing block 366 loses its squeezing force and slides and separates into the receiving plate 361 under the attraction of the magnetic block 367, opening the feeding channel; at the same time, the driven roller 33 tilts up and pushes the parts on the discharge track 403, causing them to overcome the elastic force of the metal spring 404 and enter the feeding channel, and finally fall into the middle of the receiving plate 361 under gravity; S4. Reset Fixture: The stamping head 203 moves upward, the tension adjusting component 34 and the driving component 32 reset synchronously, the conveyor belt 35 returns to its normal shape, and the receiving plate 361 returns to the horizontal state. The elastic force of the tension spring 363 drives the clamping pile 362 to retract inward, pressing against the outside of the metal part 6; the attraction of the magnetic block 365 causes the counterweight block 364 to move towards the receiving plate 361, and the wedge-shaped surfaces at both ends of the counterweight block 364 press against the sealing block 366, so that the two sealing blocks 366 close together, completing the fixation of the metal part 6 inside the receiving plate 361, preparing for subsequent stamping; S5. Stamping and Unloading: The conveyor belt 35 moves the fixed metal parts 6, transporting them directly below the stamping head 203; the stamping head 203 is activated, pressing down to stamp the parts. After stamping, the unloading robot 5 is activated, using the electromagnet on the robot to attract the formed parts and remove them from the receiving plate 361 to complete the unloading. This completes the automatic feeding, stamping, and unloading process of the metal parts 6, while maintaining stable tension on the conveyor belt 35 throughout the process.

[0020] Working principle: First, start the two motors 323 to make the entire conveyor belt 35 start to rotate. At the same time, start the vibrating feeder 402 and the punch head 203. The metal parts 6 enter the discharge track 403 through the vibrating feeder 402 and are stuck under the action of the metal spring 404. At this time, due to the downward pressure of the punch head 203, which acts on the receiving plate 361, the receiving plate 361 drives the middle part of the conveyor belt 35 to press down, thereby causing the two driven rollers 33 to tilt up. At the same time, due to the tension of the conveyor belt 35, the two driving rollers 31 move upward. During the tilting process of the driven rollers 33, they are restricted by the limit post 344, so that the movement trajectory of the driven rollers 33 becomes the sliding trajectory of the support shaft 341 along the limit groove 345. This causes the support shaft 341 to compress the buffer spring 348 inside the arc track 346, and through the buffer... The reaction force of the spring 348 keeps the movement of the entire support shaft 341 stable, thereby ensuring that the lifting process of the driven roller 33 remains stable and directionally controllable. At the same time, due to the tension, the output shaft 321 slides upward inside the movable groove 322, and the damping effect of the buffer damping cylinder 325 keeps the movement of the entire drive roller 31 stable, thereby ensuring that the deformation process of the entire conveyor belt 35 remains stable. At the same time, it ensures that the tension of the conveyor belt 35 remains stable during the pressing of the punch head 203, thereby avoiding damage to the conveyor belt 35 due to a sudden increase in tension caused by pressure. When the downward pressure generated by the punch head 203 on the conveyor belt 35 disappears, the drive roller 31 and the driven roller 33 automatically reset due to the influence of gravity and the deformation recovery force of the buffer spring 348, thereby restoring the entire conveyor belt 35 to its normal shape.

[0021] Furthermore, due to the tilting of the two driven rollers 33, the receiving plate 361 at the tilted position tilts synchronously. Because one end of the receiving plate 361 in the feeding direction tilts, the clamping pile 362 and the counterweight block 364, under the action of gravity, overcome the tension of the tension spring 363 and the magnetic force generated by the magnetic suction block 365, sliding away from the outside of the receiving plate 361. Due to the movement of the counterweight block 364, the two sealing blocks 366 are no longer affected by the squeezing force, and thus slide inwards into the receiving plate 361 under the attraction of the magnetic suction block 367, causing the two sealing blocks 366 to separate, opening the feeding channel. Furthermore, the tilting of the driven rollers 33 further moves the metal parts 6 on the discharge track 403, overcoming the force of the metal parts. The elastic force of the spring 404 enters the feeding channel of the receiving plate 361 and enters the middle of the receiving plate 361 under the influence of gravity. When the stamping head 203 moves upward, the tension adjusting component 34 resets, the driving component 32 also resets synchronously, and the conveyor belt 35 returns to normal, thereby keeping the receiving plate 361 in a horizontal state. In this way, the elastic force of the tension spring 363 drives the clamping pile 362 to retract inward and press against the outside of the metal part 6. At the same time, under the attraction of the magnetic block 365, the counterweight block 364 also moves towards the receiving plate 361. Then, through the pressure of the wedge-shaped surfaces at both ends of the counterweight block 364 on the sealing block 366, the two sealing blocks 366 close together, thereby completing the fixation of the metal part 6.

[0022] When the fixed metal parts 6 are transported to the bottom of the stamping head 203, the stamping head 203 is activated to perform stamping and forming operations. After stamping, the parts are attracted by the electromagnet of the unloading robot 5 to perform unloading operations. This completes the automatic feeding, stamping and unloading of the entire metal parts 6 while ensuring that the tension of the tree hole chain belt remains stable.

Equipment Start-up: Start the two motors (323) corresponding to the conveyor belt (35) to make the conveyor belt (35) start to rotate. At the same time, start the vibrating feeder (402) and the punch head (203). The metal parts (6) enter the discharge track (403) through the vibrating feeder (402) and are stuck under the action of the metal spring (404) in the track, which prepares for subsequent feeding and processing. At this time, each piece of equipment is in the initial working state, waiting for the subsequent processing action to be triggered, ensuring that the initial position and running state of each component before linkage are normal. S2. Pressing and tension adjustment: The punch head (203) presses down, and the force is transmitted to the receiving plate (361). The receiving plate (361) drives the middle part of the conveyor belt (35) to press down, which in turn drives the two driven rollers (33) to lift up. At the same time, the tension of the conveyor belt (35) drives the two active rollers (31) to move upward. When the driven rollers (33) lift up, they are restricted by the limiting piles (344). The support shaft (341) slides along the limiting groove (345) on the arc track (346) and squeezes the buffer spring (348). The output shaft (321) of the active roller (31) slides in the movable groove (322) and is affected by the buffer damping cylinder (325) to ensure that the conveyor belt (35) is stable in deformation and constant in tension, and to avoid damage to the belt due to pressure. S3. Feeding plate: The driven roller (33) tilts up and drives the corresponding receiving plate (361) to tilt up synchronously. After one end of the receiving plate (361) tilts up in the feeding direction, the pressing pile (362) and the counterweight (364) slide to the outside of the receiving plate (361) under the action of gravity, overcoming the tension of the tension spring (363) and the magnetic force of the magnetic block one (365). After the counterweight (364) slides, the sealing block (366) loses the squeezing force and slides and separates into the receiving plate (361) under the attraction of the magnetic block two (367). The feeding channel is opened. At the same time, the driven roller (33) tilts up and pushes the parts on the discharge track (403) to overcome the elastic force of the metal spring (404) and enter the feeding channel. Finally, it falls into the middle of the receiving plate (361) under gravity. S4. Reset the fastener: The stamping head (203) moves upward, the tension adjusting component (34) and the driving component (32) reset synchronously, the conveyor belt (35) returns to normal shape, the receiving plate (361) returns to the horizontal state, the elastic force of the tension spring (363) drives the clamping pile (362) to contract inward, clamping the outside of the metal part (6), the attraction of the magnetic block (365) causes the counterweight block (364) to move towards the receiving plate (361), the wedge-shaped surfaces at both ends of the counterweight block (364) squeeze the sealing block (366), so that the two sealing blocks (366) close together, completing the fixation of the metal part (6) inside the receiving plate (361), preparing for subsequent stamping; S5. Stamping and unloading: The conveyor belt (35) drives the fixed metal parts (6) to move and transport them to the bottom of the stamping head (203). The stamping head (203) is started and the stamping head (203) presses down to stamp the parts. After the stamping is completed, the unloading robot (5) is started. The electromagnet on the robot is used to attract the formed parts and remove them from the receiving plate (361) to complete the unloading. Thus, the complete processing flow of automatic feeding, stamping and unloading of metal parts (6) is realized, and the tension of the conveyor belt (35) is kept stable throughout the process.
