DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 of 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.

[0028] The present invention will be further described below in conjunction with embodiments.

[0029] Embodiments of the present invention

[0030] Reference Figures 1 to 3 As shown, a stamping device for automobile bracket production includes a stamping machine 1. Inside the top of the stamping machine 1, a hydraulic press 11 is fixedly connected. The bottom of the hydraulic press 11 is detachably connected with an upper die 12. The hydraulic press 11 is used to drive the upper die 12 to move up and down. On the inner upper surface of the stamping machine 1, a lower die 13 is fixedly connected. The upper die 12 and the lower die 13 are extrusion-fitted. The extrusion between the upper die 12 and the lower die 13 is used to produce the bracket. This technology is prior art and will not be elaborated in detail in this embodiment.

[0031] After the sheet metal is stamped into parts, the longer waste sheet metal will occupy more storage space, resulting in a decrease in the utilization rate of the storage area, and more space is required for loading during transportation, thus increasing the transportation cost. Therefore, the waste can be wound by a winding device.

[0032] The winding mechanism includes conveying rollers 14 symmetrically and fixedly connected to the inner upper surface of the stamping machine 1. The conveying rollers 14 are used to convey the original sheet metal. On the right end inside the stamping machine 1, a servo motor 16 is fixedly connected. The output shaft of the servo motor 16 is fixedly connected to the right end of the rear conveying roller 14. The output end of the servo motor 16 is used to drive the rear conveying roller 14 to rotate. On the outer surface of the right end of the rear conveying roller 14, a synchronous belt 17 is drivingly connected. The front end of the synchronous belt 17 is drivingly connected to the outer surface of the right end of the front conveying roller 14. The synchronous belt 17 is used to drive the two conveying rollers 14 to rotate simultaneously.

[0033] On the left end of the rear conveying roller 14, a rotating gear 15 is fixedly connected. On the outer surface of the left end of the rotating gear 15, a conveyor belt 112 is drivingly connected. The rear end of the conveyor belt 112 is drivingly connected to a transmission wheel 111. The left end of the transmission wheel 111 is rotatably connected to the left side of the stamping machine 1. The rotating gear 15 is used to drive the transmission wheel 111 to rotate through the conveyor belt 112. On the outer surface of the right end of the transmission wheel 111, a moving member 113 is slidably clamped. The transmission wheel 111 is used to drive the moving member 113 to rotate. On the inner upper surface of the stamping machine 1, a support member 110 is fixedly connected. The outer surface of the moving member 113 is rotatably connected to the inside of the support member 110.

[0034] A winding roller 18 is rotatably connected to the right end of the top of the support member 110. Symmetrically penetrating chutes are formed on the outer surface of the moving member 113. The chutes on the outer surface of the moving member 113 are slidably connected to the inner wall of the winding roller 18. When the moving member 113 rotates, it is used to drive the winding roller 18 to rotate. When the winding roller 18 rotates, it is used to wind the waste material. A guiding member 19 is fixedly connected to the rear side of the punching machine 1. The inner wall of the top of the guiding member 19 is used to block the waste material on the outer surface of the winding roller 18. A moving frame 1131 is fixedly connected to the right end of the moving member 113. A plurality of inclined slots are formed through the outer surface of the moving frame 1131. Expansion rods 1132 are slidably connected to the inner sides of the inclined slots of the moving frame 1131. The inclined slots of the moving frame 1131 are in pressing fit with the outer surfaces of the expansion rods 1132. The expansion rods 1132 are used to hook the waste material. The outer surfaces of the expansion rods 1132 slidably penetrate through the outer surface of the winding roller 18.

[0035] The principle of winding the waste material by the winding mechanism in this embodiment is as follows: Before the staff punches the sheet, the servo motor 16 can be started preferentially. At this time, the output shaft of the servo motor 16 can drive the rear conveying roller 14 to rotate. When the rear conveying roller 14 rotates, it can drive the front conveying roller 14 to rotate simultaneously through the synchronous belt 17. At this time, the sheet can pass through the inside of the front conveying roller 14. As the front conveying roller 14 rotates, it can drive the sheet to move into the punching machine 1. Since the inside of the hydraulic press 11 is electrically connected to the inside of the servo motor 16, when the hydraulic press 11 drives the upper die 12 to move downward, the output shaft of the servo motor 16 will stop rotating, and the downward movement of the upper die 12 can squeeze the sheet to form a bracket part.

[0036] When the hydraulic press 11 drives the upper die 12 to move upward, at this time, the output shaft of the servo motor 16 can continue to drive the conveying roller 14 to rotate. When the front conveying roller 14 rotates, it can continue to push the sheet backward. When the rear side of the sheet is punched, the rear conveying roller 14 can move the rear end of the sheet waste, so that the conveying roller 14 can automatically push the sheet and can also prevent the sheet from shifting during punching.

[0037] And as the rear conveying roller 14 rotates, it will drive the rotating gear 15 to rotate. When the rotating gear 15 rotates, it will drive the driving wheel 111 to rotate simultaneously through the conveyor belt 112. When the driving wheel 111 rotates, it will drive the moving member 113 to rotate simultaneously. Since the chute of the moving member 113 is slidably connected to the inner wall of the winding roller 18, when the moving member 113 rotates, it will drive the winding roller 18 to rotate simultaneously. And when the moving member 113 rotates, it will drive the expansion rod 1132 to rotate simultaneously through the moving frame 1131. The rear conveying roller 14 can drive the sheet waste to move backward, and the upper surface of the rotating plate 114 can support the sheet waste.

[0038] As the telescopic rod 1132 rotates when the sheet waste moves backward, it can hook the sheet waste and rotate at the same time, prompting the sheet waste to be wound around the outer surface of the winding roller 18. And when the sheet waste gradually winds and increases on the outer surface of the winding roller 18, it will squeeze the upper surface of the rotating plate 114, prompting the rotating plate 114 to swing slightly clockwise. And the swinging rotating plate 114 will drive the connecting torsion spring 115 to twist slightly. The rotating plate 114 that fits the sheet waste can prevent the tail of the sheet from colliding with the surroundings. The wound waste can be more easily classified and stored, facilitating the subsequent recycling and reuse processes. And the wound waste occupies less space, can more effectively utilize the warehouse or factory space, reduce storage costs, and improve space utilization rate.

[0039] The wound sheet waste can also be further compressed by a compression device.

[0040] Reference Figure 3 As shown, the compression mechanism includes a support frame 2 fixedly connected to the rear side of the stamping machine 1. A driving motor 25 is fixedly connected to the left side of the support frame 2. The output shaft of the driving motor 25 is fixedly connected with a rotating lead screw 21. The output shaft of the driving motor 25 is used to drive the rotating lead screw 21 to rotate. A pushing frame 22 is slidably connected to the outer surface of the rotating lead screw 21. The rotating lead screw 21 is used to drive the pushing frame 22 to slide left and right. The bottom of the pushing frame 22 is slidably connected to the outer surface of the top of the support frame 2. The support frame 2 is used to limit the sliding of the pushing frame 22. The top of the pushing frame 22 is slidably connected to the outer surface of the support member 110. The top of the pushing frame 22 is used to slide left and right between the support member 110 and the outer surface of the winding roller 18. A first strong magnet 23 is fixedly connected to the left side of the top of the pushing frame 22. A fixing member 26 is fixedly connected to the outer surface of the left end of the moving member 113. The moving member 113 is used to drive the fixing member 26 to rotate. A second strong magnet 24 is fixedly connected to the right end of the fixing member 26. The ends of the first strong magnet 23 and the second strong magnet 24 that are close to each other attract each other with opposite polarities.

[0041] The compression principle of the waste material after winding by the compression mechanism in this embodiment is as follows: In the initial state, the bottom of the push frame 22 is threadedly connected to the left end of the outer surface of the rotating screw rod 21. When the winding roller 18 finishes winding the sheet waste, the driving motor 25 can be started, so that the output shaft of the driving motor 25 drives the rotating screw rod 21 to rotate. As the rotating screw rod 21 rotates, it drives the push frame 22 to slide to the right. When the top of the push frame 22 slides to the right on the outer surface of the support member 110, it drives the first strong magnet 23 to slide at the same time. Since the first strong magnet 23 and the second strong magnet 24 attract each other with opposite polarities, when the first strong magnet 23 moves to the right, it drives the second strong magnet 24 to move at the same time. When the second strong magnet 24 moves to the right, it drives the moving member 113 to move at the same time through the fixing member 26. And when the moving member 113 moves to the right, it can also rotate at the same time. When the moving member 113 moves to the right, it drives the moving frame 1131 to move at the same time. As the moving frame 1131 moves to the right, the inclined groove of the moving frame 1131 can squeeze the outer surface of the telescopic rod 1132, so that the telescopic rod 1132 can be disengaged from the clamping connection with the sheet waste and contract into the inside of the winding roller 18.

[0042] When the fixing member 26 moves to the right and fits with the right end of the support member 110, at this time, the fixing member 26 can be blocked by the right end of the support member 110. As the push frame 22 drives the first strong magnet 23 to move further to the right, the first strong magnet 23 can be separated from the adsorption of the second strong magnet 24, and the right side of the top of the push frame 22 can squeeze the wound sheet waste, so that the sheet waste can move to the right and be compressed on the outer surface of the winding roller 18, thus facilitating the waste device and transportation.

[0043] When the waste material is compressed, the output shaft of the driving motor 25 can drive the rotating screw rod 21 to rotate in the reverse direction. The rotating screw rod 21 rotating in the reverse direction drives the first strong magnet 23 to move to the left through the push frame 22. After the first strong magnet 23 moves a certain distance to the left, it can re-adsorb the second strong magnet 24 and drive the second strong magnet 24 to move to the left at the same time. When the second strong magnet 24 moves to the left, it drives the moving member 113 to move at the same time through the fixing member 26. When the moving member 113 moves to the left inside the support member 110, it drives the moving frame 1131 to move at the same time. When the moving frame 1131 moves to the left, the inclined groove of the moving frame 1131 can squeeze the outer surface of the telescopic rod 1132, so that the telescopic rod 1132 moves to the outer surface of the winding roller 18 and returns to its initial state.

[0044] When the wound and compressed waste material is moved to the outer surface of the right end of the winding roller 18, it takes extra time for the staff to remove the waste material from the outer surface of the winding roller 18, resulting in a decrease in production efficiency. Therefore, the wound waste material can be automatically pushed out by the pushing mechanism.

[0045] The pushing mechanism includes a fixing plate 3 fixedly connected to the rear side of the stamping machine 1. A support column 31 is slidably connected to the inner side of the fixing plate 3. The left end of the support column 31 is clamped to the inner wall of the right end of the winding roller 18. The support column 31 is used to support the right end of the winding roller 18. A fixing rod 33 is fixedly connected to the outer surface of the right end of the support column 31. The outer surface of the top of the fixing rod 33 is slidably connected to the inner side of the top of the fixing plate 3. A compression spring 32 is fixedly connected to the inner side of the right end of the fixing rod 33. The left end of the compression spring 32 is fixedly connected to the right side of the fixing plate 3. The compression spring 32 is used to drive the support column 31 and the fixing rod 33 to move in a reset manner. A fixing block 34 is fixedly connected to the outer surface of the top of the pushing frame 22. The pushing frame 22 is used to drive the fixing block 34 to move left and right. The left end of the fixing rod 33 is in extrusion fit with the right end of the fixing block 34.

[0046] The principle of automatically pushing out the waste material after winding by the pushing mechanism in this embodiment is as follows: In the initial state, the compression spring 32 is in a natural and relaxed state. As the pushing frame 22 slides to the right on the outer surface of the support member 110, it can drive the fixing block 34 to slide simultaneously. When the fixing block 34 slides to the right, it can fit with the left end of the fixing rod 33 and prompt the fixing rod 33 to move to the right. When the fixing rod 33 moves to the right, it can not only drive the support column 31 to move simultaneously but also move the compression spring 32 to a compressed state. When the support column 31 moves to the right, it can be disengaged from the clamping connection with the right end of the winding roller 18. At this time, as the pushing frame 22 slides to the right, it can drive the wound and compressed waste material to move simultaneously. When the waste material moves to the right on the outer surface of the winding roller 18, it can automatically detach from the outer surface of the winding roller 18, thus eliminating the need for manual intervention, making the production process smoother, reducing the time for cleaning waste material during production, and timely cleaning the waste material on the outer surface of the winding roller 18 can avoid production interruption caused by waste material accumulation.

[0047] After the waste material is automatically taken out, at this time, the pushing frame 22 can drive the fixing block 34 to move left for reset. When the fixing block 34 moves left, it will be disengaged from the left end of the fixing rod 33. At this time, the compression spring 32 in a stretched state can drive the support column 31 and the fixing rod 33 to move left for reset. When the support column 31 moves left, the left end of the support column 31 can be reinserted into the right end of the winding roller 18 to support the winding roller 18.

[0048] When the waste material falls off from the outer surface of the winding roller 18, the limiting mechanism can drive the rotating plate 114 to turn over, and a collision occurs between the pushing frame 22 and the rotating plate 114 when the pushing frame 22 moves.

[0049] Reference Figure 2 and Figure 5As shown in the figure, the limiting mechanism includes an extrusion member 41 fixedly connected to the bottom of the pushing frame 22. The pushing frame 22 is used to drive the extrusion member 41 to move left and right. A guiding member 4 is slidably connected to the front side of the extrusion member 41. The left end of the guiding member 4 is inclined. The outer surface of the front side of the extrusion member 41 is in extrusion fit with the inclined surface of the guiding member 4. The extrusion member 41 is always used to drive the guiding member 4 to move up and down. The upper surface of the left end of the guiding member 4 is fixedly connected to a connecting frame 42. The outer surface of the top end of the connecting frame 42 is slidably connected to the left end of the rear conveying roller 14. The left end of the rotating plate 114 is fixedly connected to a rotating member 43. The lower surface of the top of the connecting frame 42 is in extrusion fit with the upper surface of the rotating member 43.

[0050] The principle of the limiting mechanism driving the automatic rotation of the rotating plate 114 in this embodiment is as follows: In the initial state, the connecting torsion spring 115 is in a natural and relaxed state. As the pushing frame 22 moves to the right to extrude the waste, the pushing frame 22 can drive the extrusion member 41 to move simultaneously. When the extrusion member 41 moves to the right, it can extrude the inclined surface of the guiding member 4, prompting the guiding member 4 to move downward. When the guiding member 4 moves downward, it will drive the connecting frame 42 to move simultaneously. When the connecting frame 42 moves downward, it can extrude the upper surface of the rotating member 43, enabling the rotating member 43 to drive the rotating plate 114 to swing clockwise. And when the rotating plate 114 swings, it will drive the connecting torsion spring 115 to rotate to the energy storage state. After the rotating plate 114 swings, it will be in a vertical state, thus not affecting the rightward sliding of the pushing frame 22.

[0051] As the pushing frame 22 moves leftward for resetting, it will drive the extrusion member 41 to move simultaneously. When the extrusion member 41 moves leftward, the outer surface of the bottom of the extrusion member 41 can be extruded by the inclined surface of the guiding member 4, prompting the guiding member 4 to move upward for resetting. As the guiding member 4 moves upward, it can drive the connecting frame 42 to move simultaneously. After the lower surface of the top of the connecting frame 42 is separated from the upper surface of the rotating member 43, at this time, the connecting torsion spring 115 in the energy storage state can drive the rotating plate 114 to rotate counterclockwise for resetting, and when the rotating plate 114 rotates, it can drive the rotating member 43 to rotate for resetting, so that the rotating member 43 returns to the initial state again.

[0052] And as the upper die 12 moves upward after stamping is completed, it can drive the connecting member 44 to move simultaneously. When the connecting member 44 moves upward, it will drive the ejecting member 45 to move simultaneously. When the ejecting member 45 moves upward, it can jack up the produced part upward, facilitating the taking out of the part.
