The stamping mechanism includes a driving device and an upper die. The driving device fixedly penetrates through the top of the fixing frame, and the upper die is fixedly installed at the output end of the driving device.

The plate member moves to apply a thrust to the U-shaped plate, and the U-shaped plate moves towards the cross plate under the influence of the thrust. The clamping plate is slidably installed on the inner wall of the carrying frame, the first elastic sheet is arranged between the clamping plate and the carrying frame, the support plate slidably penetrates through the top of the carrying frame, and the first spring is arranged between the support plate and the carrying frame. The clamping plate stretches the first elastic sheet during the movement, and the first elastic sheet deforms under the stretching. A card slot is opened on the side of the cross plate close to the triggering block, and a limiting groove is opened on the inner wall of the cross plate.

[0007] According to the above technical solution, an arc surface one is opened on the side of the U-shaped plate close to the clamping plate, and an inclined surface one is opened on the side of the clamping plate close to the arc surface one.

[0008] According to the above technical solution, the clamping plate is elastic, and a first corrugation is opened on the side of the clamping plate away from the U-shaped plate. The first corrugation of the clamping plate contacts the side wall of the plate member during the movement, so that the clamping plate continues to move to apply a clamping force to the plate member.

[0009] According to the above technical solution, it further includes a discharging device and an auxiliary device; the discharging device includes a placement plate, a telescopic plate, a second spring, a moving plate, a cylindrical rod, a clamping plate and a Z-shaped piece. When the portal plate moves towards the cross plate, it contacts the moving plate. The movement of the portal plate exerts a thrust on the moving plate, and the moving plate moves towards the placement plate under the influence of the thrust. The placement plate is fixedly penetrated through the inner and outer walls of the carrying frame. The telescopic plate slides through the side of the placement plate away from the cross plate. The second spring is arranged between the telescopic plate and the placement plate. During the movement of the telescopic plate, the second spring is compressed, and the compressed second spring stores energy under the action of its own elasticity. The moving plate is fixedly installed at one end of the telescopic plate away from the placement plate. The cylindrical rod is fixedly installed on the circumferential surface of the telescopic plate. The cylindrical rod slides through the top of the placement plate. The clamping plate slides through the top of the telescopic plate. The Z-shaped piece is arranged between the clamping plate and the telescopic plate.

[0010] According to the above technical solution, the size of the clamping plate is adapted to the card slot. The Z-shaped piece has elasticity, and the squeezed Z-shaped piece restores itself under the action of its own elasticity. The restored Z-shaped piece exerts an upward thrust on the clamping plate, and the clamping plate moves upward under the influence of the thrust.

[0011] According to the above technical solution, an arc surface two is opened at the top of the clamping plate, and the arc surface two contacts the inner wall of the cross plate. The surface of the arc surface two of the clamping plate that contacts the cross plate separates during the movement, so that the restriction exerted by the cross plate on the clamping plate is released.

[0012] According to the above technical solution, the auxiliary device includes a loading plate, a rotating shaft, a resisting piece, a blocking plate, a limiting plate, a second elastic piece and a pull rod. The cylindrical rod contacts the side of the resisting piece close to the blocking plate.

[0013] According to the above technical solution, an arc surface three is opened at one end of the blocking plate close to the resisting piece, and the arc surface three contacts the side of the resisting piece close to the cylindrical rod. The reset of the rotating shaft drives the resisting piece to rotate towards the blocking plate, and the side of the resisting piece close to the blocking plate collides with the arc surface three during the rotation to generate vibration.

[0014] The present invention provides a rotary continuous stamping device for sheet metal of automobile parts. It has the following beneficial effects:

[0015] (1) In the rotating continuous stamping device for sheet metal of automobile parts, the corrugation of the clamping plate contacts the side wall of the plate, so that the clamping plate continues to move to apply clamping force to the plate. When the plate is received by the carrying frame, the clamping plate automatically applies clamping force to the plate to ensure that the plate is stably maintained at the specified position during the movement, thereby ensuring the accuracy of continuous stamping. The fixed frame applies supporting force to the support plate, and the support plate stabilizes the carrying frame under the influence of the supporting force. The support plate positions and provides support for the carrying frame, making the carrying frame more stable during the stamping process, thereby reducing the error during stamping.

[0016] (2) In the rotary continuous stamping device for sheet metal of automobile parts, the telescopic plate is limited and cannot move, so that the deformed No. 2 spring is limited and cannot be restored. By automatically limiting the telescopic plate, it is ensured that the deformed No. 2 spring will not actively restore and eject the plate during the production process, thereby improving the safety of continuous stamping. The moving plate applies a thrust to the door-shaped plate, so that the door-shaped plate moves and drives the plate to move away from the mounting frame. The limit of the telescopic plate is released by the trigger block, so that the deformed No. 2 spring provides kinetic energy for the telescopic plate, ensuring that the stamped plate can stably eject from the vacant position.

[0017] (3) In the rotating continuous stamping device for sheet metal of automobile parts, the three collisions between the plate and the arc surface generate vibration. Due to resonance, the generated vibration is transmitted to the cylindrical rod. Continuous vibration is generated through the intermittent collision between the plate and the blocking plate, which prevents the telescopic plate from getting stuck during movement and causing plate failure, thereby improving the smoothness of the overall movement. The loading plate drives the plate to move, so that the cylindrical rod does not vibrate in contact with the plate during movement. By actively releasing the limit of the loading plate, the operator can perform vibration according to the usage situation, which helps to extend the service life of the plate.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 9, an embodiment of the present invention is: a rotary continuous stamping device for automotive parts sheet metal, including a processing table 1, a feeding plate 2 is fixedly installed on the top of the processing table 1, a pushing mechanism 3 is fixedly installed on the top of the processing table 1, a fixing frame 4 is fixedly installed on the top of the processing table 1, a stamping mechanism 5 is arranged on the fixing frame 4, the stamping mechanism 5 includes a driving device and an upper die, the driving device is fixedly penetrated through the top of the fixing frame 4, the upper die is fixedly installed at the output end of the driving device, a lower die 6 is fixedly installed at the bottom of the fixing frame 4, a triggering mechanism 7 is arranged on the top of the processing table 1, the triggering mechanism 7 includes an electric push rod and a triggering block, the electric push rod is fixedly installed on the top of the processing table 1, the triggering block is fixedly installed at the output end of the electric push rod, a positioning groove is opened on the top of the fixing frame 4, and a moving device is further included; wherein, the moving device includes a servo motor 8, a cross plate 9, a carrying frame 10, a portal plate 11, a clamping plate 12, a first elastic piece 13, a support plate 14, and a first spring 15. The servo motor 8 is fixedly penetrated through the inner and outer walls of the processing table 1, the cross plate 9 is fixedly installed at the output end of the servo motor 8, the carrying frame 10 is fixedly installed on the side of the cross plate 9 away from the servo motor 8, the portal plate 11 is slidably installed on the inner wall of the carrying frame 10, the clamping plate 12 is slidably installed on the inner wall of the carrying frame 10, the first elastic piece 13 is arranged between the clamping plate 12 and the carrying frame 10, the support plate 14 is slidably penetrated through the top of the carrying frame 10, the first spring 15 is arranged between the support plate 14 and the carrying frame 10, a card slot is opened on the side of the cross plate 9 close to the triggering block, and a limiting groove is opened on the inner wall of the cross plate 9. When receiving the plate member through the carrying frame 10, the clamping plate 12 automatically applies a clamping force to the plate member, improving the stable contact between the carrying frame 10 and the plate member, and effectively avoiding the situation of the plate member shifting during the production process.

[0030] An arc surface one is opened on the side of the portal plate 11 close to the clamping plate 12, a slope surface one is opened on the side of the clamping plate 12 close to the arc surface one, and a sliding groove is opened on the top of the cross plate 9. By opening the arc surface one and the slope surface one, it is ensured that when the portal plate 11 and the clamping plate 12 are in contact, the arc surface one can smoothly drive the clamping plate 12 to move, thereby improving the stability of the work.

[0031] The clamping plate 12 is elastic, a first corrugation is opened on the side of the clamping plate 12 away from the portal plate 11, and a positioning rod is fixedly installed at the bottom of the support plate 14. The support plate 14 positions and provides support for the carrying frame 10, making the carrying frame 10 more stable during stamping, thereby reducing the error during stamping.

[0032] During the operation of this embodiment, the plate is guided by the feeding plate 2 and moves to the designated area. The pushing mechanism 3 is started, and the output end of the pushing mechanism 3 moves to drive the plate to move towards the cross plate 9. During the movement, the plate contacts the inner wall of the carrying frame 10, enabling the carrying frame 10 to receive the plate. At the same time, the plate contacts the portal plate 11 during the movement, and the movement of the plate exerts a thrust on the portal plate 11. Affected by the thrust, the portal plate 11 moves towards the cross plate 9. The first arc surface of the portal plate 11 contacts the first inclined surface during the movement, and the continuous movement of the first arc surface exerts a pressure on the first inclined surface. Affected by the pressure, the clamping plate 12 moves away from the support plate 14. During the movement, the clamping plate 12 stretches the first elastic piece 13, and the first elastic piece 13 deforms under the stretching. At the same time, the first corrugation of the clamping plate 12 contacts the side wall of the plate during the movement, enabling the clamping plate 12 to continue moving and exert a clamping force on the plate. When the carrying frame 10 receives the plate, the clamping plate 12 automatically exerts a clamping force on the plate, preventing the plate from shifting during the production process. The servo motor 8 is started, and the output end of the servo motor 8 drives the cross plate 9 to rotate clockwise. The rotation of the cross plate 9 drives the carrying frame 10 to rotate clockwise, and the rotation of the carrying frame 10 drives the plate to move. When the plate moves above the lower die 6, the output end of the servo motor 8 stops rotating. The stamping mechanism 5 is started, and the output end of the driving device drives the upper die to move downward. During the movement of the upper die, it contacts the top of the support plate 14, and the movement of the upper die exerts a downward thrust on the support plate 14. Under the action of the thrust, the support plate 14 moves downward. During the movement, the support plate 14 squeezes the first spring 15, and the first spring 15 deforms under the squeeze. At the same time, the positioning rod of the support plate 14 contacts the inner wall of the positioning groove during the movement, and the support plate 14 continues to move and contacts the fixed frame 4, enabling the fixed frame 4 to exert an upward supporting force on the support plate 14. Affected by the supporting force, the support plate 14 stabilizes the carrying frame 10. The upper die continues to move and contacts the plate and stamps the plate. By positioning and providing support for the carrying frame 10 through the support plate 14, the carrying frame 10 is more stable during stamping, thereby reducing the error during stamping.

[0033] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, a discharging device and an auxiliary device are further included; the discharging device includes a placing plate 161, a telescopic plate 162, a second spring 163, a moving plate 164, a cylindrical rod 165, a clamping plate 166 and a Z-shaped piece 167. The placing plate 161 is fixedly penetrated through the inner and outer walls of the carrying frame 10. The telescopic plate 162 is slidably penetrated through the side of the placing plate 161 away from the cross plate 9. The second spring 163 is arranged between the telescopic plate 162 and the placing plate 161. The moving plate 164 is fixedly installed at one end of the telescopic plate 162 away from the placing plate 161. The cylindrical rod 165 is fixedly installed on the circumferential surface of the telescopic plate 162. The cylindrical rod 165 is slidably penetrated through the top of the placing plate 161. The clamping plate 166 is slidably penetrated through the top of the telescopic plate 162. The Z-shaped piece 167 is arranged between the clamping plate 166 and the telescopic plate 162. The cylindrical rod 165 contacts the inner wall of the chute. By triggering the block, the limit on the telescopic plate 162 is released, and the deformed second spring 163 provides kinetic energy for the telescopic plate 162 to ensure that the plate can be stably ejected under the action of the thrust.

[0034] The size of the clamping plate 166 is adapted to the card slot. The Z-shaped piece 167 has elasticity. By automatically limiting the telescopic plate 162, it is ensured that the deformed second spring 163 during the production process will not actively recover and eject the plate, thereby ensuring the integrity of the plate during the production process.

[0035] An arc surface two is opened on the top of the clamping plate 166. The arc surface two contacts the inner wall of the cross plate 9. By opening the arc surface two on the clamping plate 166, the friction between the clamping plate 166 and the cross plate 9 is effectively reduced, thereby prolonging the service life of the clamping plate 166.

[0036] The auxiliary device includes a loading plate 171, a rotating shaft 172, a resisting piece 173, a blocking plate 174, a limiting plate 175, a second elastic piece 176 and a pull rod 177. The loading plate 171 is slidably installed on the top of the cross plate 9. The rotating shaft 172 is rotatably installed on the inner wall of the loading plate 171. The resisting piece 173 is fixedly installed on the circumferential surface of the rotating shaft 172. The blocking plate 174 is fixedly installed on the inner wall of the loading plate 171. The limiting plate 175 is slidably penetrated through the inner and outer walls of the loading plate 171. The second elastic piece 176 is arranged between the limiting plate 175 and the loading plate 171. The pull rod 177 is fixedly installed on the side of the limiting plate 175 away from the loading plate 171. The limiting plate 175 contacts the inner wall of the limiting groove. A scroll spring is arranged between the rotating shaft 172 and the loading plate 171. The resisting piece 173 has elasticity. By actively releasing the limit on the loading plate 171, the operator can perform vibration according to the usage situation, which helps to prolong the service life of the resisting piece 173.

[0037] One end of the baffle 174 close to the abutting piece 173 is provided with a third arc surface, and the third arc surface contacts the surface of the abutting piece 173 close to the cylindrical rod 165. Continuous vibration is generated by the intermittent collision between the abutting piece 173 and the baffle 174, avoiding jamming when the telescopic plate 162 moves, resulting in faults in the plate parts, thereby improving the smoothness of the overall movement.

[0038] During the operation of this embodiment, when the portal plate 11 moves towards the cross plate 9, it contacts the moving plate 164. The movement of the portal plate 11 exerts a thrust on the moving plate 164. Affected by the thrust, the moving plate 164 moves towards the placing plate 161. The movement of the moving plate 164 drives the telescopic plate 162 to move towards the placing plate 161. The movement of the telescopic plate 162 drives the cylindrical rod 165 to move towards the placing plate 161. At the same time, during the movement of the telescopic plate 162, it squeezes the second spring 163, and the second spring 163 deforms under the extrusion. The deformed second spring 163 stores energy under the action of its own elasticity. At the same time, the movement of the telescopic plate 162 drives the clamping plate 166 to move away from the moving plate 164. The second arc surface of the clamping plate 166 separates from the surface contacting the cross plate 9 during the movement, so that the squeezed Z-shaped piece 167 restores under the action of its own elasticity. The restoration of the Z-shaped piece 167 exerts an upward thrust on the clamping plate 166. Affected by the thrust, the clamping plate 166 moves upward. The clamping plate 166 moves upward through the card slot. The telescopic plate 162 is restricted by the cross plate 9 and cannot move, so that the deformed second spring 163 is restricted and cannot restore. By automatically limiting the telescopic plate 162, it is ensured that the deformed second spring 163 will not actively restore and eject the plate parts during the production process, which helps to improve the safety of production. After stamping, the servo motor 8 drives the cross plate 9 to rotate clockwise. The rotation of the cross plate 9 drives the carrying frame 10 to move below the triggering mechanism 7. The triggering mechanism 7 is started, and the output end of the electric push rod drives the trigger block to move downward. During the movement, the trigger block passes through the card slot, so that the trigger block contacts the top of the clamping plate 166. The trigger block continues to move and exerts a downward pressure on the clamping plate 166. Affected by the pressure, the clamping plate 166 moves downward. During the movement, the clamping plate 166 squeezes the Z-shaped piece 167, and the Z-shaped piece 167 deforms under the extrusion. At the same time, the surface of the clamping plate 166 contacting the card slot separates during the movement, so that the limit applied by the cross plate 9 to the telescopic plate 162 is released. The restored second spring 163 drives the telescopic plate 162 to move away from the placing plate 161. The movement of the telescopic plate 162 drives the moving plate 164 to move away from the placing plate 161. During the movement, the moving plate 164 exerts a thrust on the portal plate 11, so that the movement of the portal plate 11 drives the plate parts to move away from the carrying frame 10. The surface of the plate parts contacting the carrying frame 10 separates during the movement, thus completing the disassembly of the plate parts. By the trigger block releasing the limit on the telescopic plate 162, the deformed second spring 163 provides kinetic energy for the telescopic plate 162, ensuring that the plate parts can be stably ejected;

[0039] When the cylindrical rod 165 moves away from the moving plate 164, the cylindrical rod 165 contacts the side of the abutting piece 173 close to the blocking plate 174. The movement of the cylindrical rod 165 exerts a thrust on the abutting piece 173. Affected by the thrust, the abutting piece 173 rotates away from the blocking plate 174. The side of the abutting piece 173 that contacts the third arc surface separates during the rotation. At the same time, the rotation of the abutting piece 173 drives the rotating shaft 172 to rotate away from the blocking plate 174. During the rotation of the rotating shaft 172, the volute spring is stretched. The volute spring deforms under the stretching force. The cylindrical rod 165 continues to move and separates from the side that contacts the blocking plate 174. The thrust exerted by the cylindrical rod 165 on the blocking plate 174 gradually decreases, causing the deformed volute spring to recover under its own elasticity. The recovery of the volute spring drives the rotating shaft 172 to rotate back to its original position. The reset of the rotating shaft 172 drives the abutting piece 173 to rotate towards the blocking plate 174. The side of the abutting piece 173 close to the blocking plate 174 collides with the third arc surface during the rotation, generating vibrations. Due to resonance, the generated vibrations are transmitted to the cylindrical rod 165, making the telescopic plate 162 move more smoothly. Through the intermittent collision between the abutting piece 173 and the blocking plate 174, continuous vibrations are generated, preventing the telescopic plate 162 from getting stuck during movement and causing faults in the plate components, thereby improving the overall smoothness of movement. When the maintenance of the telescopic plate 162 is completed, the operator can actively stop using the abutting piece 173 and pull the pull rod 177 to move away from the loading plate 171. The movement of the pull rod 177 drives the limiting plate 175 to move away from the loading plate 171. During the movement of the limiting plate 175, the second elastic piece 176 is stretched. The second elastic piece 176 deforms under the stretching force. At the same time, the side of the limiting plate 175 that contacts the limiting groove separates during the movement, releasing the limit exerted by the cross plate 9 on the loading plate 171. Push the pull rod 177 to move away from the carrying frame 10. The movement of the pull rod 177 drives the limiting plate 175 to move away from the carrying frame 10. The movement of the limiting plate 175 drives the loading plate 171 to move away from the carrying frame 10. The movement of the loading plate 171 drives the abutting piece 173 to move away from the cylindrical rod 165, so that the cylindrical rod 165 does not contact the abutting piece 173 during movement to generate vibrations. By actively releasing the limit on the loading plate 171, the operator can control the generation of vibrations according to the usage situation, which helps to extend the service life of the abutting piece 173.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and deformations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
