When the moving plate on the moving block moves leftward until it conflicts with the U-shaped blocking plate, the moving block continues to move leftward, and then drives the support rod to rotate in the direction away from the moving plate through the moving plate, so that the two positioning brackets move in the expansion direction, so that the positioning bracket is separated from the automobile door frame steel plate, and the automobile door frame steel plate falls from the moving block. , completing the unloading operation of the automobile door frame steel plate, the hydraulic cylinder drives the stamping plate and the tooth plate to move downward, so that the movable plate gradually breaks away from the contact with the U-shaped obstruction plate, and under the elastic force of the first spring, drives the positioning support plate to move in the direction of approaching each other, so as to realize the merging of the two positioning support plates, and drives the stamping plate, the special-shaped plate and the tooth plate to move by the hydraulic cylinder, so as to realize the stamping, loading and unloading operations of the automobile door frame steel plate, and the rapid positioning in the loading process, so that the stamping operation has good continuity, thereby saving unnecessary time and improving the efficiency of stamping production.

[0020] 2. The present invention starts the cylinder and energizes the electromagnet to generate magnetic force. The cylinder drives the electromagnet to move downward, so that the electromagnet absorbs the automobile door frame steel plate to be punched, and the automobile door frame steel plate to be punched is unloaded onto the loading plate after the punching is completed. Then the rotating shaft drives the loading plate and the automobile door frame steel plate to be punched to flip 180 degrees, so that the automobile door frame steel plate to be punched is flipped to face directly upward, and then the motor is started. The motor drives the second screw rod to rotate, so that the second screw rod drives the U-shaped frame, the loading plate and the automobile door frame steel plate with punching to move upward into the moving block. In the process of driving the punching plate downward by the hydraulic cylinder, the contraction of the positioning support plate is completed. When the positioning plate to be determined supports the automobile door frame steel plate to be processed and the positioning support plate is not completely merged, the second screw rod is rotated counterclockwise to drive the loading plate to move downward to the bottom of the operating table, and the feeding operation of the automobile door frame steel plate to be punched is completed. The feeding operation of the automobile door frame steel plate to be punched is realized by flipping and moving the loading plate, and the labor of manual feeding is reduced, thereby effectively improving the production efficiency.

[0021] 3. The present invention drives the L-shaped connecting rod and the collar to move downward through the electric telescopic rod, and further drives the sleeve to move downward through the collar, so that the sleeve is gradually sleeved on the outside of the transmission rod. At this time, the hemisphere on the inside of the sleeve squeezes and contacts the transmission rod. Under the elastic force of the third spring, the hemisphere is stuck in the spherical groove on the transmission rod, so that the sleeve, the worm and the transmission rod rotate synchronously, and then the worm drives the worm gear meshing therewith to rotate, and the worm gear further drives the rotating shaft to rotate, providing power for the rotation of the rotating shaft, and the electric telescopic rod drives the L-shaped connecting rod and the collar to move the rod upward, and drives the sleeve upward through the collar, so that the hemisphere is out of contact with the transmission rod, and the worm is in a static state, and the sleeve and the hemisphere are driven to move by the electric telescopic rod to achieve the matching state of the hemisphere and the spherical groove, and then the flipping state of the loading plate is controlled, so as to better realize the loading of the automobile door frame steel plate to be stamped.

[0045] The operation process of this embodiment is as follows: first, the initial position of the automobile door frame steel plate is placed on the positioning support plate 203 in the moving block 201, and the automobile door frame steel plate is directly below the stamping plate 402, and the hydraulic cylinder 401 is started. The hydraulic cylinder 401 drives the stamping plate 402 to punch the automobile door frame steel plate downward to complete the stamping operation on the automobile door frame steel plate. After the stamping is completed, the hydraulic cylinder 401 drives the stamping plate 402 to move upward. The hydraulic cylinder 401 synchronously drives the special-shaped plate 507 and the tooth plate 508 to move upward, so that the tooth plate 508 engages to drive the spur gear 509 to rotate, and the rotation of the spur gear 509 further drives the first screw rod 502 to rotate clockwise, so that the first screw rod 502 drives the L-shaped plate 503, the slide plate 504, the moving block 201 and the automobile door frame steel plate to move to the left. When the moving plate 207 on the moving block 201 moves to the left until it conflicts with the U-shaped blocking plate 14, the moving block 201 continues to move to the left, and then drives the support rod 208 to rotate in the direction away from the moving plate 207 through the moving plate 207. At this time, the first spring 211 connected and fixed between the baffle 210 and the concave cavity 206 is compressed, so that the two positioning support plates 203 move in the expansion direction, so that the positioning support plates 203 are out of contact with the automobile door frame steel plate, and the automobile door frame steel plate falls from the moving block 201, completing the unloading operation of the automobile door frame steel plate;

[0046] After the automobile door frame steel plate is fed to the positioning support plate 203, the hydraulic cylinder 401 drives the stamping plate 402 and the tooth plate 508 to move downward. During the downward movement, the tooth plate 508 meshes and drives the spur gear 509 and the first screw rod 502 to rotate counterclockwise, so that the first screw rod 502 drives the L-shaped plate 503, the slide plate 504, the moving block 201 and the automobile door frame steel plate to move rightward. During the rightward movement, the compressed first spring 211 begins to reset, thereby driving the two positioning support plates 203 to approach each other, realizing the merging of the two positioning support plates 203, and having a positioning effect on the automobile door frame steel plate;

[0047] In the above process, when the hydraulic cylinder 401 drives the stamping plate 402 and the tooth plate 508 to move downward, the tooth plate 508 meshes and drives the spur gear 509 and the first screw rod 502 to rotate counterclockwise, and the first screw rod 502 drives the L-shaped plate 503, the slide plate 504, the moving block 201 and the automobile door frame steel plate to move rightward. When the moving block 201 moves to contact the right inner wall of the first guide groove 7, the automobile door frame steel plate is just under the stamping plate 402, and the stamping plate 402 continues to move downward to start stamping the automobile. The door frame steel plate, with the cooperation of the slide plate 504, the guide rod 505 and the second spring 506, allows the L-shaped plate 503 to continue to move to the right, thereby not affecting the normal stamping operation of the stamping plate 402. The hydraulic cylinder 401 drives the movement of the stamping plate 502, the special-shaped plate 507 and the tooth plate 508 to synchronously realize the stamping, loading and unloading operations of the automobile door frame steel plate, as well as the rapid positioning during the loading process, so that the stamping operation has good continuity, thereby saving unnecessary time and improving the efficiency of stamping production.

By flipping and moving the loading plate 907, the loading operation of the automobile door frame steel plate to be stamped is realized, the labor of manual loading is reduced, and the production efficiency is effectively improved.

[0050] Synchronously, through the rotation of the second screw rod 1102, the second screw rod 1102 drives the first sprocket 1103 to rotate, and the first sprocket 1103 drives the second sprocket 1105 to rotate through chain engagement, and then drives the sleeve 1108 to rotate. Since the sliding rod 1110 on the transmission rod 1104 can only move in the limiting groove 1109 on the sleeve 1108, the sleeve 1108 not only drives the transmission rod 1104 to rotate, but also does not affect the movement of the transmission rod 1104 in the vertical direction.

[0051] For example 3, please refer to Figure 1-16, the third embodiment of the present invention is improved as follows on the basis of the first embodiment: the top of the partition 910 is rotatably provided with a flip control component 12 for controlling the flipping of the loading plate 907, the flip control component 12 includes a worm 1201 that is rotatably connected to the partition 910, wherein the peripheral side surface of a rotating shaft 904 is fixedly connected with a worm wheel 1202 that meshes with the worm 1201, the peripheral side surface of the worm 1201 is slidably sleeved with a sleeve 1203 that matches the transmission rod 1104, the outer peripheral side surface of the sleeve 1203 is rotatably sleeved with a collar 1204, the inner bottom of the U-shaped frame 903 is fixedly connected with an electric telescopic rod 1205, the driving end of the electric telescopic rod 1205 is fixedly connected with an L-shaped connecting rod 1206, the L-shaped connecting rod 1206 is fixedly connected to the collar 1204, and the outer peripheral side surface of the sleeve 1203 is provided with a An annular groove 1207 matching the ring 1204, a push rod 1208 symmetrically fixedly connected to the inner circumferential side of the sleeve 1203 on the circumferential side, a limit groove 1209 symmetrically opened on the inner circumferential side of the sleeve 1203 matching the two push rods 1208, a plurality of grooves 1210 evenly opened on the inner circumferential side of the sleeve 1203, a hemisphere 1211 matching the spherical groove 1107 slidably connected inside each groove 1210, a third spring 1212 fixedly connected between each hemisphere 1211 and the groove 1210, a control box 13 fixedly connected to the top of the operating table 1, a PLC controller is arranged inside the control box 13, and the PLC controller, hydraulic cylinder 401, motor 1101, electromagnet 909 and electric telescopic rod 1205 are electrically connected.

[0052] The operation process of this embodiment is as follows: the electric telescopic rod 1205 is started, so that the electric telescopic rod 1205 drives the L-shaped connecting rod 1206 and the collar 1204 to move downward, and the sleeve 1203 is further driven to move downward through the collar 1204, so that the sleeve 1203 is gradually sleeved on the outside of the transmission rod 1104. At this time, the hemispherical body 1211 on the inside of the sleeve 1203 presses and contacts the transmission rod 1104. Under the elastic force of the third spring 1212, the hemispherical body 1211 is stuck in the spherical groove 1107 on the transmission rod 1104, so that the sleeve 1203, the worm 1201 and the transmission rod 1104 rotate synchronously, and then the worm 1201 drives the worm 1201 to mesh with it. The worm gear 1202 rotates, and the worm gear 1202 further drives the rotating shaft 904 to rotate, providing power for the rotation of the rotating shaft 904, and the electric telescopic rod 1205 drives the L-shaped connecting rod 1206 and the ring 1204 to move the rod upward, and the sleeve 1203 is driven to move upward through the ring 1204, so that the hemisphere 1211 is out of contact with the transmission rod 1104, so that the worm 1201 is in a stationary state, and the sleeve 1203 and the hemisphere 1211 are driven to move by the electric telescopic rod 1205, so as to realize the matching state of the hemisphere 1211 and the spherical groove 1107, and then the flipping state of the loading plate 907 is controlled, so as to better realize the feeding of the automobile door frame steel plate to be stamped.
