[0014] The present invention provides a punching device for processing bus ducts, which has the following beneficial effects: (1) When the busbar duct processing stamping equipment encounters a deformed stamping workpiece, when the centering plate pushes the workpiece to center, the workpiece is deformed, which causes the centering plate to drive the sleeve rod to move into the connecting sleeve. Through the cooperation of the short rod, the movable rod and the connecting rod, the transmission block squeezes the transmission plate, so that the transmission plate drives the limit rod to move out of the limit hole of the connecting column. Through the cooperation of the reset spring, the connecting column can drive the bottom plate to move out of the bottom of the lower mold, so that the bottom of the deformed workpiece in the lower mold is not blocked, and the deformed workpiece falls out of the lower mold and is discharged without performing stamping operations, thereby preventing the deformed workpiece from being stamped, which easily leads to the scrapping of the workpiece and damage to the mold.

[0015] (2) The bus duct processing stamping equipment, when the reset spring drives the connecting column to move, the long block drives the push rod to squeeze the bottom of the arc block, and through the cooperation of the slide bar and the rotating block, the knocking ball is moved away from the lower mold, and the No. 1 torsion spring is compressed. When the push rod moves to extrude the arc block, the No. 1 torsion spring is in a compressed deformation state, so that the No. 1 torsion spring drives the rotating frame and the knocking ball to reset, so that the knocking ball knocks on the outer wall of the lower mold, and by generating vibration, the workpiece is conveniently discharged from the bottom of the lower mold, and metal impurities such as dust attached to the inner wall of the lower mold can be knocked off, which can improve the quality of subsequent stamping products.

[0016] (3) When the long block moves, the stamping equipment for bus duct processing will squeeze the arc surface on the top of the semicircular block, causing the semicircular block to move downward under the squeezing force, so that the long rod can drive the L-shaped connecting block to move downward. Through the cooperation of the inclined rod and the disc, the rotating rod can drive the unloading plate to rotate, so that the bottom of the unloading plate rotates to move out from the bottom of the horizontal plate, so that the fallen workpiece falls on the unloading plate for unloading, and the workpiece slides out from the bottom of the horizontal plate, which is convenient for the staff to take the material. When sliding on the unloading plate, the buffer plate and the No. 2 torsion spring can play a role in buffering the workpiece, preventing the unloading speed from being too fast, which will cause the workpiece to have too much impact on the baffle at the bottom of the unloading plate and cause damage.

The side of the transmission spring 16 away from the sleeve rod 12 is fixed to the inner wall of the connecting sleeve 14. The sleeve rod 12 passes through the side wall of the lower mold 5 and is slidably connected at the penetration point. Two groups of center plates 13 are provided, and the two groups of center plates 13 are symmetrically arranged with the center line of the lower mold 5 in the vertical direction as the symmetry axis. A short rod 17 is fixed to the top of the sleeve rod 12. The short rod 17 passes through the top of the connecting sleeve 14, and the short rod 17 can move at the penetration point of the connecting sleeve 14. A sleeve 18 is fixed to the outer wall of the connecting sleeve 14, and a connecting rod 19 is slidably installed on the inner wall of the sleeve 18. A movable rod 20 is hinged on the short rod 17, and one end of the movable rod 20 away from the short rod 17 is hinged on the connecting rod 19. A transmission block 21 is fixed to the top of the connecting rod 19, and a transmission plate 22 is slidably installed on the inner wall of the right groove of the lower mold 5. A connecting spring 23 is fixed to the bottom of the transmission plate 22, and the bottom of the connecting spring 23 is fixed to the inner wall of the groove of the outer wall of the lower mold 5. A limiting rod 24 is fixed to the bottom of the transmission plate 22, and a fixed block 26 is fixed to the outer wall of the lower mold 5. A return spring 27 is fixed to the side wall of the fixed block 26. A connecting column 25 is fixed to the side of the return spring 27 away from the fixed block 26, and one end of the connecting column 25 away from the return spring 27 is fixedly connected to the side wall of the bottom plate 7. A limiting hole is provided at the top of the connecting column 25, and the inner wall of the limiting hole fits with the outer wall of the limiting rod 24.

[0021] And when the extrusion rod 8 moves in the inclined groove section at the top of the slide groove 10, the moving block 9 will be moved away from the lower mold 5. Through the cooperation of the L-shaped connecting rod 11, the connecting sleeve 14 and the sleeve rod 12, the two groups of centering plates 13 are close to each other to center the bus duct workpiece, which is convenient for stamping operations. When the two groups of centering plates 13 are centering the bus duct, the centering plates 13 fit exactly with the bus duct workpiece.

[0022] When the limit rod 24 is in the limit hole of the connecting column 25, the reset spring 27 is in a compressed deformation state, so that the reset spring 27 will give a reaction force to the connecting column 25. When encountering a deformed bus duct workpiece, the limit rod 24 will be moved out of the limit hole, thereby releasing the limit on the connecting column 25. Through the reset spring 27, the connecting column 25 can drive the bottom plate 7 to move out of the lower mold 5, so that the bottom of the bus duct workpiece is not blocked, so that material can be discharged, preventing the deformed workpiece from being stamped, which may easily lead to the scrapping of the workpiece and damage the mold.

[0023] When the present embodiment is working: when the bus duct workpiece needs to be formed, the workpiece to be stamped is placed in the lower die 5, and then the staff walks to the control panel 6 and starts the cylinder 3 through the control panel 6 to move the upper die 4 downward. When the upper die 4 moves downward, the extrusion rod 8 can move in the inclined groove section of the slide groove 10, so that the extrusion rod 8 can squeeze the inclined groove section of the slide groove 10, and the moving block 9 can be moved in the direction away from the lower die 5 by the extrusion force, so that the L-shaped connecting rod 11 can be driven to move, so that the L-shaped connecting rod 11 can be driven to move. The rod 11 pulls the hinge rod 15, causing the hinge rod 15 to rotate at the hinge, so that the hinge rod 15 pulls the connecting sleeve 14, causing the connecting sleeve 14 to drive the sleeve rod 12 to move into the lower mold 5, so that the two sets of centering plates 13 are close to each other, and the workpiece placed in the lower mold 5 is centered, so that the stamping operation can be carried out accurately, and the product quality is improved. When encountering a deformed workpiece, the centering plate 13 will not fit with the workpiece when the two sets of centering plates 13 are close to each other, so that the centering plate 13 will be squeezed, so that the sleeve rod 12 When the sleeve rod 12 moves, the short rod 17 can be driven to squeeze the movable rod 20, so that the movable rod 20 rotates at the hinge, so that the movable rod 20 squeezes the connecting rod 19, so that the connecting rod 19 moves out of the sleeve 18. When the connecting rod 19 moves upward, the transmission block 21 can move upward to squeeze the transmission plate 22, so that the transmission plate 22 drives the connecting spring 23 to stretch, and when the transmission plate 22 moves upward, it can drive the limit rod 24 from the connecting column 2 5 is moved out, and because the reset spring 27 is in a compressed state, the reset spring 27 can drive the connecting column 25 to move, so that the connecting column 25 drives the bottom plate 7 to move out of the lower die 5, so that the bottom of the deformed workpiece is not blocked, because the downward gravity of the workpiece is much greater than the elastic force of the transmission spring 16 on the sleeve rod 12, the workpiece falls from the bottom and is discharged from the lower die 5, and the stamping operation is not performed, thereby preventing the deformed workpiece from being stamped, which may easily cause greater damage to the workpiece and lead to scrapping, and easily cause wear of the die.

[0024] When the bottom plate 7 needs to be reset, when the cylinder 3 drives the upper mold 4 to reset, when the extrusion rod 8 moves from the straight groove of the slide groove 10 to the inclined groove, when the extrusion rod 8 moves upward in the inclined groove of the slide groove 10, it can squeeze the moving block 9 to approach the lower mold 5, so that it can drive the L-shaped connecting rod 11 to move rightward, so that the L-shaped connecting rod 11 squeezes the hinge rod 15, and the hinge rod 15 rotates at the hinge, so that the hinge rod 15 squeezes the connecting sleeve 14 and the sleeve rod 12 to reset, and the sleeve rod 12 drives the two sets of center plates 13 to move away from each other for reset, and because the workpiece falls, the center plate 13 is not subjected to the squeezing force, and the transmission spring 16 is in a compressed state, so The transmission spring 16 drives the center plate 13 to reset, the sleeve rod 12 drives the short rod 17 to reset, and the short rod 17 pulls the movable rod 20, so that the movable rod 20 pulls the connecting rod 19 to move downward, so that the transmission block 21 does not squeeze the transmission plate 22, and the transmission plate 22 is manually pushed upward by the staff, and the bottom plate 7 is pushed into the lower mold 5 to compress the reset spring 27. When the limiting hole of the connecting column 25 moves to align with the limiting rod 24, the transmission plate 22 can be released. Because the connecting spring 23 is in a stretched state, the transmission plate 22 drives the limiting rod 24 to move downward, and the limiting rod 24 extends into the limiting hole to fix the connecting column 25.

[0026] By setting a knocking ball 284 to knock the outer wall of the lower mold 5 back and forth, vibration is generated, which facilitates the discharge of the workpiece from the bottom of the lower mold 5, and can knock off metal impurities such as dust attached to the inner wall of the lower mold 5, thereby improving the quality of subsequent stamping products.

[0027] The blanking assembly includes a support block 291, a rotating rod 292, a blanking plate 293, a semicircular block 295, a return spring 296, a long rod 294, an L-shaped connecting block 297, an inclined rod 298, a disc 299, a buffer plate 2931 and a second torsion spring 2932; the support block 291 is fixed to the bottom of the horizontal plate 1, the support block 291 is rotatably mounted with a rotating rod 292, the outer wall of the rotating rod 292 is fixed with a blanking plate 293, and the rotating rod 292 is fixed with a blanking plate 293.

There is an inclined rod 298, one end of the inclined rod 298 away from the L-shaped connecting block 297 is hinged to the side of the disc 299 away from the rotating rod 292, and a buffer plate 2931 is rotatably installed on the inner side of the unloading plate 293. The buffer plate 2931 is provided with a No. 2 torsion spring 2932 at the rotation point of the unloading plate 293. One side of the No. 2 torsion spring 2932 is fixed to the side wall of the buffer plate 2931, and the other side of the No. 2 torsion spring 2932 is fixed to the inner side of the unloading plate 293. Through the rotation and tilting of the unloading plate 293, the bottom of the unloading plate 293 can be rotated to move out from the bottom of the horizontal plate 1, and when the workpiece falls onto the unloading plate 293, the workpiece slides along the unloading plate 293 and slides out from the bottom of the horizontal plate 1 without being blocked by the horizontal plate 1, which is convenient for the staff to pick up the workpiece, and baffles are provided at the edges of the unloading plate 293 to prevent the workpiece from falling during unloading.

Through the buffer plate 2931 and the No. 2 torsion spring 2932, a buffering operation can be performed when the workpiece is unloaded.

[0029] When this embodiment is working: when the connecting column 25 drives the bottom plate 7 to move out of the lower mold 5, the connecting column 25 will drive the long block 281 to move, so that the long block 281 drives the push rod 282 to move, and when the push rod 282 moves to the top and contacts the bottom of the arc block 286, the push rod 282 will squeeze the bottom of the arc block 286. Because the arc block 286 is subjected to the squeezing force, the arc block 286 will move upward. When the arc block 286 moves upward, the slide bar 285 will squeeze the bottom of the rotating frame 283, causing the rotating frame 283 to rotate forward, thereby compressing and deforming the No. 1 torsion spring 287, so that the rotating frame 283 drives the knocking ball 284 away from the lower The arc block 286 is a block formed by a plurality of push rods 282 that are moved on the upper surface of the mold 5. When the push rod 282 moves to stop squeezing the arc block 286, the torsion spring 287 is in a compressed state, so that the torsion spring 287 drives the rotating frame 283 to reset, and the rotating frame 283 drives the knocking ball 284 to knock on the outer wall of the lower mold 5. When the plurality of push rods 282 move on the arc block 286, the knocking ball 284 can knock on the outer wall of the lower mold 5 back and forth. Vibration is generated to facilitate the discharge of the workpiece from the bottom of the lower mold 5, and metal impurities such as dust attached to the inner wall of the lower mold 5 can be knocked off, thereby improving the quality of subsequent stamping products.

[0030] When the long block 281 moves to contact the arc surface of the semicircular block 295, the long block 281 will squeeze the semicircular block 295, so that the semicircular block 295 will move downward under the squeezing force, driving the long rod 294 to move downward, compressing the return spring 296, and when the long rod 294 moves downward, the L-shaped connecting block 297 will squeeze the inclined rod 298, so that the inclined rod 298 squeezes the disc 299 to rotate forward, so that the disc 299 drives the rotating rod 292 and the blanking plate 293 to rotate forward, so that The bottom of the unloading plate 293 comes out from the bottom of the cross plate 1, and when the workpiece falls onto the unloading plate 293, the workpiece slides down from the unloading plate 293, which is convenient for the staff to take the material, and when the workpiece is unloading, the workpiece will hit the buffer plate 2931, causing the buffer plate 2931 to rotate, thereby compressing and deforming the No. 2 torsion spring 2932, so that the No. 2 torsion spring 2932 gives a reaction force to the buffer plate 2931, thereby buffering the workpiece and causing the workpiece to slide slowly.

[0031] When the bottom plate 7 moves to the lower mold 5 for reset, the long block 281 will not squeeze the semicircular block 295. Since the return spring 296 is in a compressed state, the semicircular block 295 will move upward for reset, and the long rod 294 will drive the L-shaped connecting block 297 to move upward, so that the L-shaped connecting block 297 pulls the inclined rod 298, and the inclined rod 298 pulls the disc 299 to reverse, so that the disc 299 drives the rotating rod 292 and the blanking plate 293 to reverse and return, and the bottom of the blanking plate 293 is retracted to the bottom of the horizontal plate 1 to prevent it from being in the unfolded state for a long time.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
