[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] The present invention provides a bending device for automobile production parts, such as Figures 1 to 13 As shown, the device comprises a main body 1, a support platform 2 is arranged on the main body 1, a carrier 3 is arranged on the top of the support platform 2, a turntable 4 is arranged on the outside of the carrier 3, the turntable 4 is a bending platform for bending wires on a bending machine in the prior art, a notch is arranged in the middle of the top of the carrier 3, support rollers 5 are symmetrically rotatably installed on the inner walls on both sides of the notch, every two opposite support rollers 5 are connected by a conveyor belt 7, support plates 6 are fixedly installed on the inner walls on both sides of the notch, the support plates 6 are located between two adjacent support rollers 5 to support the conveyor belt 7, and slide grooves are symmetrically opened on the inner walls on both sides of the notch, and the slide grooves are provided in the inner walls. A slider is provided, and a bracket 8 is fixedly installed between two sliders on the same side. A rotating shaft is rotatably installed on the bracket 8, and a closing plate 9 is fixedly installed outside the rotating shaft. One end of the rotating shaft extends to the outer sleeve of the bracket 8 and a first torsion spring 10 is provided. The two ends of the first torsion spring 10 are respectively fixedly connected to the rotating shaft and the bracket 8. A limiting component for limiting the closing plate 9 is provided on the top of the bracket 8. A driving component for driving the bracket 8 to descend and the supporting roller 5 to rotate is provided on the carrier 3. The bottom wall of the recess is symmetrically provided with inclined surfaces, and a dropping mouth 11 is provided in the middle of the bottom wall of the recess. An opening corresponding to the dropping mouth 11 is provided on the outside of the turntable 4.

[0018] When in use, the driving assembly drives the bracket 8 to descend and the support roller 5 to rotate. As the support roller 5 rotates, the conveyor belt 7 is driven to rotate, thereby moving the impurity particles on the conveyor belt 7, and finally bringing the impurity particles into the drop port 11. Under the action of gravity, the impurity particles fall onto the inclined surface and slide to the drop port 11, and fall out to the outside through the opening. As the conveyor belt 7 rotates, the clean surface of the conveyor belt 7 is located at the top. When the bracket 8 descends, the limiting assembly closes the closing plate 9, so that the closing plate 9 cannot rotate upward, and then Pass the flat wire through between the closing plate 9 and the conveyor belt 7, place the flat wire on the conveyor belt 7, and then continue to drive the bracket 8 to descend, and cooperate with the closing plate 9 to press the flat wire. Since the top of the conveyor belt 7 is clean at this time, there will be no agglomerated impurity particles that will lift the wire and make it unable to be horizontal. In addition, the closing plate 9 flattens the wire so that the entire wire is in a horizontal state. Subsequently, the turntable 4 can be rotated to cooperate with the bending column above it to bend the wire. Since the wire is horizontal, the bending quality of the bent wire is greatly improved.

[0019] like Figures 4 to 5 As shown, the driving assembly includes a gear 12, a movable groove connected to the slide groove is opened on one side of the top of the carrier 3, one end of the support roller 5 extends into the movable groove and is fixedly connected to the gear 12, a vertical plate 16 is slidably installed in the movable groove, and a plurality of pairs of side plates are fixedly installed on one side of the vertical plate 16 at equal intervals from top to bottom, and a circular shaft is rotatably installed between each pair of side plates, and a fixed sleeve is provided with teeth 13 matching with the gear 12 on the circular shaft, and a protrusion 14 is provided on the upper part of the side of the tooth 13 close to the vertical plate 16, and a downwardly facing arc surface is provided at the bottom of the protrusion 14, and the protrusion 14 contacts with the vertical plate 16, and one end of the circular shaft extends to the outer sleeve of the side plate and is provided with a second torsion spring 15, and the two ends of the second torsion spring 15 are respectively fixedly connected to the side plate and the circular shaft, and a limiting component for limiting its rotation direction is provided on one side of the gear 12, and the slider on the bracket 8 is fixedly connected to the vertical plate 16, and an electric push rod 17 is fixedly installed on the top of the carrier 3, and the telescopic end of the electric push rod 17 is fixedly connected to the vertical plate 16 through a connecting frame 18.

[0020] The electric push rod 17 is started to shorten its telescopic end, thereby bringing the connecting frame 18, the vertical plate 16, the slider, and the bracket 8 down. Due to the presence of the protrusion 14, the tooth 13 cannot rotate upward, so the tooth 13 remains in a horizontal state. As the vertical plate 16 descends, the tooth 13 drives the gear 12 to rotate forward, thereby driving the support roller 5 to rotate, and then driving the transmission belt 7 and the support roller 5 on the other side to rotate, starting the electric push rod 17 to extend it, and vice versa, the vertical plate 16 and the bracket 8 can be raised. As the vertical plate 16 rises, the side plate, the round shaft, and the tooth 13 move accordingly. After the tooth 13 conflicts with the gear 12, due to the gear 12 Restricted by the limiting component, the gear 12 cannot reverse at this time, so the tooth 13 is resisted by the gear 12 and rotates downward with the circular shaft, and at the same time, the second torsion spring 15 is twisted to torsionally deform it, so that it avoids the gear 12. When the tooth 13 is separated from the gear 12, the second torsion spring 15 releases the force to rotate and reset the circular shaft and the gear 12, so that the gear 12 does not rotate during the rising process of the vertical plate 16, and the support roller 5 does not rotate. When the flat wire is placed on the conveyor belt 7, the tooth 13 is completely separated from the gear 12 at this time. Therefore, when the vertical plate 16 and the closing plate 9 are subsequently lowered, the gear 12 will not rotate and the conveyor belt 7 remains stationary.

[0021] like Figure 6 to Figure 7 As shown, the limiting assembly includes a ratchet 19 fixedly connected to the outside of the gear 12, and a ratchet pawl 20 cooperating with the ratchet 19 is rotatably mounted on the inner wall of the movable groove through a shaft.

[0022] Through the cooperation between the ratchet 19 and the pawl 20, the gear 12 can only rotate forward and cannot be reversed, so that the support roller 5 can only rotate forward and cannot be reversed.

[0023] like Figure 12 to Figure 13 As shown, the limit assembly includes a card frame 21 fixedly mounted on the top of the bracket 8, a card plate 22 is slidably mounted inside the card frame 21, a cavity is provided inside the bracket 8, a reset assembly for driving the card plate 22 to reset is provided in the cavity, and inclined surfaces 23 cooperating with the card plate 22 are provided on the inner walls on both sides of the recess.

[0024] The bracket 8 descends, bringing with it the card frame 21 and the card plate 22. After the card plate 22 contacts the inclined surface 23, it is squeezed and moves in the direction away from the inclined surface 23, thereby extending to the top of the closing plate 9 to restrict it and prevent it from rotating upward. When the bracket 8 is reset, the reset component drives the card plate 22 to reset, thereby canceling the restriction on the closing plate 9.

[0025] like Fig.13As shown, the reset assembly includes a winding rod 24 rotatably installed in the cavity, and both ends of the winding rod 24 are sleeved with a third torsion spring 25, and the two ends of the third torsion spring 25 are respectively fixedly connected to the inner wall of the cavity and the winding rod 24, and the outside of the winding rod 24 is fixedly connected with a pull rope 26, and the pull rope 26 is wound on the winding rod 24. A groove 27 is provided at the bottom of the clamping plate 22, and one end of the pull rope 26 away from the winding rod 24 extends to the outside of the cavity and is fixedly connected to the bottom wall of the groove 27.

[0026] The movement of the card plate 22 in the direction away from the inclined surface 23 will pull the winding rod 24 to rotate through the pull rope 26, thereby twisting the third torsion spring 25 to cause its torsional deformation to generate a force. As the bracket 8 rises and resets, the third torsion spring 25 continuously releases the force to reset and rotate the winding rod 24 to rewind the pull rope 26, thereby resetting the card plate 22.

[0027] like Figures 8 to 9 As shown, a notch groove is provided on the bottom side of the support plate 6 away from the gear 12, a clapper 28 is slidably provided inside the notch groove, the bottom of the clapper 28 abuts against the bottom wall of the conveyor belt 7, and a toggle assembly for driving the clapper 28 to move vertically is provided on the top of the clapper 28.

[0028] When operating in an environment with high humidity, some foreign particles will be adsorbed on the conveyor belt 7 and cannot be completely detached when the conveyor belt 7 rotates to the drop port 11. Therefore, when the support roller 5 rotates, the toggle assembly drives the clapper 28 to continuously move up and down, thereby clapping the bottom of the conveyor belt 7, and then the foreign particles adsorbed on the conveyor belt 7 are knocked off, thereby cleaning the adsorbed foreign particles and improving the cleaning effect of the conveyor belt 7.

[0029] like Fig. 9 As shown, the toggle assembly includes a toggle plate 29 fixedly connected to the top of the clapper plate 28, a vertical groove is provided on the inner wall of one side of the notch groove, one end of the toggle plate 29 is slidably installed in the vertical groove, the top of the toggle plate 29 is fixed to the top wall of the vertical groove by a spring 30, an annular groove is provided on the outside of the supporting roller 5 close to the toggle plate 29, and a lifting plate 31 cooperating with the toggle plate 29 is fixedly installed equidistantly on the inner wall of the annular groove.

[0030] The support roller 5 rotates with the lifting plate 31, and the lifting plate 31 contacts with the toggle plate 29 and moves up with the toggle plate 29, and the toggle plate 29 moves up with the clapping plate 28, and at the same time, the toggle plate 29 compresses the spring 30 to deform it. When the lifting plate 31 leaves the toggle plate 29, the spring 30 releases its force and moves the toggle plate 29 and the clapping plate 28 down and reset, so that the clapping plate 28 hits the conveyor belt 7 to make it vibrate. As multiple lifting plates 31 are continuously contacted and separated from the toggle plates 29, the conveyor belt 7 can be continuously vibrated.

[0031] like Fig. 9 As shown, the conveyor belt 7 is specifically configured as a steel conveyor belt.

[0032] Working principle: When in use, start the electric push rod 17 to shorten its telescopic end, thereby bringing the connecting frame 18, the vertical plate 16, the slider, and the bracket 8 down. Due to the presence of the protrusion 14, the tooth 13 cannot rotate upward, so the tooth 13 remains in a horizontal state. As the vertical plate 16 descends, the gear 12 drives the gear 13 to rotate forward, thereby driving the support roller 5 to rotate, and then driving the conveyor belt 7 and the support roller 5 on the other side to rotate, thereby moving the foreign particles on the conveyor belt 7, and finally bringing the foreign particles into the drop port 11. Under the action of gravity, the foreign particles fall onto the inclined surface and slide to the drop port 11, and fall out to the outside through the opening. As the conveyor belt 7 rotates, The surface of the clean conveyor belt 7 is located at the top, and the bracket 8 descends with the card frame 21 and the card plate 22. After the card plate 22 contacts the inclined surface 23, it is squeezed and moves in the direction away from the inclined surface 23. The movement of the card plate 22 in the direction away from the inclined surface 23 will pull the winding rod 24 to rotate through the pull rope 26, thereby twisting the third torsion spring 25 to torsion deformation to generate a force. Finally, the card plate 22 is located above the closing plate 9 to restrict it from rotating upward, and then the electric push rod 17 is stopped. At this time, the uppermost tooth 13 is separated from the gear 12, and then the flat wire is passed through the closing plate 9 and the conveyor belt 7, and the flat wire is placed on the conveyor belt 7, and the electric push rod 17 is started again to retract it. The short circuit causes the bracket 8 to descend, thereby causing the closing plate 9 to descend. At this time, the gear 12 is stationary, so the support roller 5 and the conveyor belt 7 are stationary, and the closing plate 9 presses the flat wire. Since the top of the conveyor belt 7 is clean at this time, there will be no agglomerated impurity particles that will lift the wire and make it unable to be horizontal. In addition, the closing plate 9 flattens the wire so that the entire wire is in a horizontal state. Subsequently, the wire can be bent by rotating the turntable 4 in cooperation with the bending column above it. Since the wire is horizontal, the bending quality of the bent wire is greatly improved. When working in an environment with high humidity, some impurity particles will be adsorbed on the conveyor belt 7, and cannot be completely bent when the conveyor belt 7 rotates to the drop port 11. The lifting plate 31 is completely disengaged, so when the support roller 5 rotates, the lifting plate 31 rotates, the lifting plate 31 contacts the toggle plate 29 and brings the toggle plate 29 up, and the toggle plate 29 brings the clapping plate 28 up, and at the same time, the toggle plate 29 compresses the spring 30 to deform it, and when the lifting plate 31 leaves the toggle plate 29, the spring 30 releases its force and brings the toggle plate 29 and the clapping plate 28 down and resets, so that the clapping plate 28 slaps the conveyor belt 7 to make it vibrate, and as the multiple lifting plates 31 are continuously separated from the toggle plates 29, the conveyor belt 7 can be continuously vibrated, thereby slapping the bottom of the conveyor belt 7, and then the foreign particles adsorbed on the conveyor belt 7 are knocked off, so as to clean the adsorbed foreign particles and improve the cleaning effect of the conveyor belt 7;When it is necessary to remove the wire, the electric push rod 17 is started to extend it, and vice versa, the bracket 8 and the vertical plate 16 are lifted up. As the vertical plate 16 rises, the side plate, the round shaft, and the tooth 13 move accordingly. After the tooth 13 contacts the gear 12, the gear 12 is restricted by the restriction component, so that the gear 12 cannot be reversed at this time. Therefore, the tooth 13 is resisted by the gear 12 and the round shaft rotates downward, and the second torsion spring 15 is twisted to make it twisted and deformed, so as to avoid the gear 12. When the tooth 13 is separated from the gear 12, the second torsion spring 15 releases the force to rotate the round shaft and the gear 12 to reset. , so that the gear 12 does not rotate and the support roller 5 does not rotate during the rise of the vertical plate 16. As the bracket 8 rises and resets, the third torsion spring 25 continuously releases its force to reset and rotate the winding rod 24 to rewind the pull rope 26, thereby resetting the clamping plate 22 and canceling the restriction on the closing plate 9, so that the closing plate 9 can rotate upward. At this time, the wire is passed through the closing plate 9 and removed. The wire presses against the closing plate 9 to rotate with the shaft to twist the first torsion spring 10 to generate a force. When the wire leaves the closing plate 9, the first torsion spring 10 releases its force to reset the shaft and the closing plate 9. ;

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
