Description

Technical Field

[0001] The present invention relates to the technical field of contact piece production equipment, and specifically to an integrated machine for stamping, cutting, and profiling contact pieces. Background Art

[0002] Contact pieces include moving contact pieces and static contact pieces. The moving contact piece is an electrical component in an electronic device, mainly used in devices such as switches and controllers. It is a movable contact head that faces the static contact piece fixed on the circuit board, and realizes the on-off control of the circuit through mechanical movement. When producing contact pieces, it is necessary to stamp and form them, then cut off the arc-shaped notches at the edges through cutting, and then press out a three-dimensional shape through profiling.

[0003] After retrieval, a Chinese patent with the publication number CN212736353U discloses a stamping and cutting machine, which includes a stamping device. The stamping device includes a pressure plate, two pairs of positioning columns, and two connecting rods. The opposite sides of the two connecting rods are respectively fixedly connected to the middle parts of the left and right sides of the pressure plate. The opposite ends of the two connecting rods are provided with bases. A pair of sliders are arranged on the front and rear surfaces of the two connecting rods. Two screw rods drive the connecting rods provided with thread one to move up and down through thread two. The up and down movement of the connecting rods drives the pressure plate to move up and down to achieve the effect of stamping and cutting. The two connecting rods enhance the stability of the pressure plate during the downward pressing process. During the downward pressing process of the pressure plate, the lower ends of the four positioning columns first contact the placement plate. The material to be cut is placed on the upper surface of the placement plate, and the round rod presses the material for positioning to prevent the material from shifting when the pressure plate moves downward. The spring protects the material from being damaged due to excessive pressure of the round rod.

[0004] In the above technology, although the design of structures such as the pressure plate and the round rod can press the material tightly, thereby avoiding the material from shifting during stamping and cutting, when the material is cut, it usually needs to be extruded and formed. After the above device cuts the material, it is necessary to transport the material to another extrusion device to complete the extrusion and forming of the material, resulting in an increase in operating steps and a reduction in work efficiency. In addition, the above device cannot collect the waste materials cut off, thereby increasing the subsequent cleaning difficulty.

[0005] Therefore, the present invention provides an integrated machine for stamping, cutting, and profiling contact pieces. Summary of the Invention

Detailed implementation manner

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: As Figure 1-6As shown in the figure, the present invention provides a one - machine for stamping, cutting and profiling of contact pieces, including a workbench 1. At the top of the workbench 1, a support frame 2 is fixedly connected. At one end of the top of the support frame 2, a first cylinder 4 is fixedly connected. The output end of the first cylinder 4 is fixedly connected with a mounting frame 5. At one end of the mounting frame 5, a stamping head 6 is fixedly connected. Below the stamping head 6 on the workbench 1, a stamping table 7 is fixedly connected. Adjacent to the stamping head 6 on the mounting frame 5, an upper cutting knife 8 is fixedly connected. Below the upper cutting knife 8 on the workbench 1, a lower cutting knife 9 is fixedly connected. Adjacent to the lower cutting knife 9 on the workbench 1, a placing table 10 is fixedly connected. Above the placing table 10 on the mounting frame 5, a second pressing plate 11 is arranged. Adjacent to the second pressing plate 11 on the mounting frame 5, an upper die 12 is arranged. Below the upper die 12 on the workbench 1, a lower die 13 is arranged; There is a stamping hole 14 directly below the stamping head 6 on the stamping table 7. At one end of the stamping head 6 on the mounting frame 5, a fixing plate 15 is fixedly connected. The stamping head 6 is fixedly connected to the bottom of the fixing plate 15. At both ends of the stamping head 6 at the bottom of the fixing plate 15, two first springs 16 are respectively fixedly connected. Inside the first springs 16 on the fixing plate 15, a first damper 17 is fixedly connected. The bottoms of the first springs 16 and the first damper 17 are jointly fixedly connected with a first pressing plate 18; At the top of the second pressing plate 11, a second spring 19 is fixedly connected. Inside the first springs 16 on the second pressing plate 11, a second damper 20 is fixedly connected. The tops of the second spring 19 and the second damper 20 are both fixedly connected with the mounting frame 5; At the top of the workbench 1, two extrusion rollers 37 are fixedly rotatably connected adjacent to the stamping head 6. Between the stamping head 6 and the lower blade on the workbench 1, a transition roller 38 is rotatably connected;

[0031] In this embodiment, first, drive two extrusion rollers to rotate synchronously in opposite directions, so as to convey the material to the stamping table 7. The material for producing the contact piece is usually a strip-shaped metal sheet. When one end of the material moves onto the stamping table 7, stop driving the extrusion rollers to rotate, and drive the mounting frame 5 to move downward through the first cylinder 4, thereby driving the fixing plate 15, the stamping head 6, and the first pressing plate 18 to move downward. During this process, the first pressing plate 18 will first contact the material and extrude the material. At this time, the first spring 16 and the first damper 17 will contract to ensure the stability of the material during subsequent stamping. When the first pressing plate 18 presses the material tightly, the stamping head 6 will continue to move downward under the drive of the first cylinder 4 to punch the material. When the punching is completed, drive the mounting frame 5 to move upward through the first cylinder 4, so that the stamping head 6 and the first pressing plate 18 are separated from the material. Then drive the material to move again through the extrusion rollers. At this time, the punched end of the material will pass above the lower blade through the transition roller 38 and move onto the placing table 10. Then drive the mounting frame 5 to move downward again through the first cylinder 4 to drive the upper blade and the second pressing plate 11 to move downward. During this process, the second pressing plate 11 will first contact the material and press the material tightly. At this time, the second spring 19 and the second damper 20 will contract to ensure the stability of the material during subsequent shearing. During the shearing process, the stamping head 6 will punch other parts of the material synchronously, so that punching and shearing can be carried out synchronously. The heights of the first pressing plate 18 and the second pressing plate 11 are the same to facilitate pressing the material tightly at the same time. When the punched part of the material is sheared off, it is necessary to transport this part to the lower mold 13. Then drive the mounting frame 5 to move downward again through the first cylinder 4 to drive the upper mold 12 to move downward to extrude and form the sheared material. During the pressing process, the stamping head 6 and the upper cutting knife 8 will punch and shear the material synchronously, so that punching, shearing, and pressing can be carried out synchronously.

[0032] At one end of the top of the workbench 1, a handling mechanism 3 is provided. The handling mechanism 3 includes a moving plate 301, a hydraulic cylinder 302, a connecting pipe 305, and a suction cup 306. The moving plate 301 is slidably connected to the workbench 1. A hydraulic cylinder 302 is rotatably connected to the top of the moving plate 301. The output end of the hydraulic cylinder 302 is fixedly connected to a connecting arm 303. One end of the connecting arm 303 is fixedly connected to a mounting plate 304. A plurality of connecting pipes 305 are fixedly connected to the middle of the mounting plate 304. The bottom of the connecting pipe 305 communicates with a suction cup 306. At both ends of the moving plate 301 on the workbench 1, chutes 26 are respectively provided. At both ends of the bottom of the moving plate 301, sliders 307 are respectively fixedly connected. The sliders 307 are slidably connected to the chutes 26. A lead screw 27 is rotatably connected in the chute 26 of the workbench 1. The lead screw 27 is threadedly connected to the slider 307. One end of the top of the connecting arm 303 is fixedly connected to a second vacuum pump 308. The input end of the second vacuum pump 308 communicates with a shunt pipe 309. The shunt pipe 309 communicates with the top of the connecting pipe 305.

[0033] In this embodiment, when the punched material is cut by the upper cutter 8 and the lower cutter 9, at this time, it is necessary to transport the material from the placement table 10 to the lower mold 13. Then, the lead screw 27 is driven to rotate, thereby driving the slider 307 and the moving plate 301 to move, so that the moving plate 301 moves to a position adjacent to the placement table 10. Then, the hydraulic cylinder 302 is rotated, thereby driving the connecting arm 303 and the mounting plate 304 to move, so that the mounting plate 304 moves directly above the placement table 10. Then, the hydraulic cylinder 302 is used to drive the connecting arm 303 and the mounting plate 304 to move downward, thereby driving the suction cup 306 to move downward. When the suction cup 306 contacts the material on the placement table 10, the second vacuum pump 308 is opened at this time. The inside of the connecting pipe 305 and the suction cup 306 is evacuated through the second vacuum pump 308, so that the suction cup 306 can smoothly adsorb the material. Then, the mounting plate 304 is driven to move upward again through the hydraulic cylinder 302, thereby driving the suction cup 306 and the material to move upward. Then, the lead screw 27 is driven to rotate again, thereby driving the moving plate 301 to move to a position adjacent to the lower mold 13, so as to drive the mounting plate 304 and the material to move directly above the lower mold 13. Then, the mounting plate 304 and the material are driven to move downward through the hydraulic cylinder 302, so that the material is placed on the lower mold 13, and the second vacuum pump 308 is closed, so that the material is separated from the suction cup 306, thereby realizing the transportation of the material.

[0034] One end of the top of the movable plate 301 is fixedly connected to a first motor 310. The output end of the first motor 310 is fixedly connected to a first gear 311. One end of the bottom of the hydraulic cylinder 302 is fixedly connected to a second gear 312. The first gear 311 is meshed with the second gear 312. One end of the lead screw 27 extends to the outside of the workbench 1 and is fixedly connected to a synchronous pulley 28. The two synchronous pulleys 28 are driven by a synchronous belt 29. One end of the side wall of the workbench 1 is fixedly connected to a second motor 30. The output end of the second motor 30 is fixedly connected to the synchronous pulley 28;

[0035] In this embodiment, the second motor 30 is driven to rotate the synchronous pulley 28 and the synchronous belt 29, thereby driving the two lead screws 27 to rotate, and then driving the movable plate 301 to move. The first motor 310 is driven to rotate the first gear 311, thereby driving the second gear 312 and the hydraulic cylinder 302 to rotate, so that the mounting plate 304 can be rotated to directly above the placing plate.

[0036] A cavity 21 is provided inside the upper die 12. A plurality of through holes 22 are provided at the bottom of the upper die 12. The through holes 22 communicate with the cavity 21. One end of the top of the upper die 12 is fixedly connected to a first vacuum pump 23. The input end of the first vacuum pump 23 communicates with the cavity 21; An installation frame 5 is located at one end of the upper die 12 and is fixedly connected to a second cylinder 24. The upper die 12 is fixedly connected to the output end of the second cylinder 24. A discharge port 25 is provided at a position adjacent to the lower die 13 on the workbench 1;

[0037] In this embodiment, when the upper die 12 and the lower die 13 extrude the material into a mold, the first vacuum pump 23 is opened at this time to evacuate the cavity 21 inside the upper die 12. Among them, the through holes 22 at the bottom of the upper die 12 are in contact with the material. Therefore, the negative pressure generated in the cavity 21 will adsorb the material. At this time, when the first cylinder 4 drives the installation frame 5 and the upper die 12 to move upward, the material will be driven to move upward. When the material detaches from the lower die 13, the second cylinder 24 is used to drive the upper die 12 and the material to move in the direction of the discharge port 25. When the upper die 12 and the material move directly above the discharge port 25, the first vacuum pump 23 is closed at this time to make the negative pressure in the cavity 21 disappear. At this time, the material will detach from the upper die 12 and fall into the discharge port 25 and be discharged.

[0038] One end of the bottom of the workbench 1 is fixedly connected to a slag collecting box 31. The top of the slag collecting box 31 communicates with the punching hole 14. One end of the side wall of the slag collecting box 31 is communicated with an exhaust pipe 32. A filter screen 33 is provided on the inner wall of the slag collecting box 31 at the exhaust pipe 32. One end of the inside of the exhaust pipe 32 is fixedly connected to a negative pressure fan 34. Two door bodies 35 are installed at one end of the side wall of the slag collecting box 31. A plurality of ventilation holes 36 are provided in the middle of the placing table 10. The ventilation holes 36 communicate with the slag collecting box 31;

[0039] In this embodiment, the slag collecting box 31 is used to collect the waste generated during punching. During the punching and shearing processes, the negative pressure fan 34 needs to be turned on. The negative pressure fan 34 evacuates the inside of the slag collecting box 31 to vacuum, so that the waste and dust generated by punching can smoothly flow into the slag collecting box 31. In addition, the ventilation holes 36 on the placing table 10 are connected to the slag collecting box 31. Under the action of the negative pressure fan 34, the cut material on the placing table 10 will be adsorbed. In this way, when the second pressing plate 11 moves upward, the material will not shift, thus ensuring that the subsequent handling mechanism 3 can accurately transport the material to the lower die 13.

[0040] One end of the extrusion roller 37 is fixedly connected to a third gear 39. The two third gears 39 mesh with each other. One end of the top of the workbench 1 is fixedly connected to a third motor 40. The output end of the third motor 40 is fixedly connected to the third gear 39.

[0041] In this embodiment, the third motor 40 drives the two gears to rotate synchronously and reversely, thereby driving the two extrusion rollers 37 to rotate synchronously and reversely to realize the conveying of the material.

[0042] Working principle: First, place one end of the material between the two extrusion rollers 37. Then, drive the two gears to rotate synchronously and reversely through the third motor 40, thereby driving the two extrusion rollers 37 to rotate synchronously and reversely, so as to convey the material to the punching table 7. When one end of the material moves to the punching table 7, stop driving the extrusion roller to rotate at this time, and drive the mounting frame 5 to move downward through the first cylinder 4, thereby driving the fixed plate 15, the punching head 6 and the first pressing plate 18 to move downward. During this process, the first pressing plate 18 will first contact the material and press the material. At this time, the first spring 16 and the first damper 17 will contract to ensure the stability of the material during subsequent punching. When the first pressing plate 18 presses the material tightly, the punching head 6 will continue to move downward under the drive of the first cylinder 4 to punch the material. When the punching is completed, drive the mounting frame 5 to move upward through the first cylinder 4 at this time, so that the punching head 6 and the first pressing plate 18 are away from the material. Then drive the material to move through the extrusion roller again. At this time, the punched end of the material will pass above the lower blade through the transition roller 38 and move to the placing table 10. At this time, drive the mounting frame 5 to move downward through the first cylinder 4 again to drive the upper blade and the second pressing plate 11 to move downward. During this process, the second pressing plate 11 first contacts the material and presses the material tightly. At this time, the second spring 19 and the second damper 20 will contract to ensure the stability of the material during subsequent shearing. During the shearing process, the punching head 6 will punch other parts of the material synchronously, so that punching and shearing can be carried out synchronously.

[0043] When the punched part of the material is sheared off, it is necessary to transport this part to the lower die 13. At this time, the second motor 30 drives the synchronous pulley 28 and the synchronous belt 29 to rotate, thereby driving the two lead screws 27 to rotate, and then driving the slider 307 and the moving plate 301 to move. Further, the moving plate 301 is moved to a position adjacent to the placement table 10. Then, the first motor 310 drives the first gear 311 to rotate, thereby driving the second gear 312 and the hydraulic cylinder 302 to rotate, and then driving the connecting arm 303 and the mounting plate 304 to move. Further, the mounting plate 304 is moved directly above the placement table 10. Then, the hydraulic cylinder 302 drives the connecting arm 303 and the mounting plate 304 to move downward, thereby driving the suction cup 306 to move downward. When the suction cup 306 contacts the material on the placement table 10, the second vacuum pump 308 is opened at this time. The second vacuum pump 308 evacuates the inside of the connecting pipe 305 and the suction cup 306, so that the suction cup 306 can successfully adsorb the material. Then, the hydraulic cylinder 302 drives the mounting plate 304 to move upward again, thereby driving the suction cup 306 and the material to move upward. Then, the second motor 30 drives the lead screw 27 to rotate again, thereby driving the moving plate 301 to move to a position adjacent to the lower die 13, and then driving the mounting plate 304 and the material to move directly above the lower die 13. Then, the hydraulic cylinder 302 drives the mounting plate 304 and the material to move downward, placing the material on the lower die 13, and closing the second vacuum pump 308 to separate the material from the suction cup 306. Then, the first motor 310 drives the hydraulic cylinder 302 to rotate again, thereby driving the mounting plate 304 to rotate and moving the mounting plate 304 away from above the lower die 13. After that, the first cylinder 4 drives the mounting frame 5 to move downward again, thereby driving the upper die 12 to move downward to extrude and form the sheared material. During the pressing process, the punching head 6 and the upper cutting knife 8 will punch and shear the material synchronously, so that punching, shearing, and pressing can be carried out synchronously;

[0044] After the upper die 12 and the lower die 13 extrude and form the material, the first vacuum pump 23 is turned on at this time to evacuate the internal cavity 21 of the upper die 12. The through hole 22 at the bottom of the upper die 12 contacts the material. Therefore, the negative pressure generated in the cavity 21 will adsorb the material. When the first cylinder 4 drives the mounting bracket 5 and the upper die 12 to move upward at this time, the material will be driven to move upward. When the material detaches from the lower die 13, the second cylinder 24 drives the upper die 12 and the material to move in the direction of the discharge port 25 at this time. When the upper die 12 and the material move directly above the discharge port 25, the first vacuum pump 23 is turned off at this time to make the negative pressure in the cavity 21 disappear. At this time, the material will detach from the upper die 12 and fall into the discharge port 25 and be discharged. During the stamping and shearing processes, the negative pressure fan 34 needs to be turned on. The negative pressure fan 34 evacuates the inside of the slag collection box 31, so that the waste and dust generated during punching can smoothly flow into the slag collection box 31. In addition, the ventilation hole 36 on the placement table 10 is communicated with the slag collection box 31. Under the action of the negative pressure fan 34, the material cut on the placement table 10 will be adsorbed. In this way, when the second pressing plate 11 moves upward, the material will not shift, thereby ensuring that the subsequent handling mechanism 3 can accurately transport the material onto the lower die 13.
