Description

Technical Field

[0001] The invention relates to the technical field of stamping devices, in particular to a stamping die for combined hardware cabinet parts. Background Art

[0002] Hardware cabinets are an important facility in modern life. They are cabinet systems formed by the combination and installation of various hardware parts. In order to ensure the normal opening and closing of the cabinets, hinges, an important connecting part, are used. In order to ensure the strength of the hinges, the production of hinges usually adopts the integral stamping technology.

[0003] The existing stamping work mostly places the plate at the stamping work position, and then performs two stamping operations to make the hinge finally formed. However, after pre-bending, the workers need to accurately place the bent plate at the position of the stamping groove for curling. In this process, the workers need to hold it in a fixed state all the time, which is extremely dangerous. The plate may also shake due to the worker's unstable hand, resulting in the plate being unable to fit the stamping die, affecting the final curling forming effect, and is likely to produce waste. In addition, the existing stamping work does not perform auxiliary operations of the core when curling. The lack of positioning of the curvature and the center of the curling circle also makes it easier to produce the problem of curling failure, which has a serious impact on the stamping production effect of the hinge.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] Reference Figure 1-Figure 10 A stamping die for a combined hardware cabinet component comprises a base 1, a guide slope 2 is provided on one side of the top of the base 1, an upper pressing seat 3 is slidably connected to the top of the base 1, telescopic rods 4 are symmetrically fixedly connected to the two sides of the bottom of the upper pressing seat 3, the telescopic rods 4 are fixedly connected to the inside of the base 1, an arc-shaped pressing groove 5 is provided on one side of the bottom of the upper pressing seat 3, and the arc-shaped pressing groove 5 is located above the guide slope 2, a cylinder 6 is fixedly connected to the inside of the base 1, a connecting piece 7 is fixedly connected to the output end of the cylinder 6, a rack 8 is fixedly connected to the other end of the connecting piece 7, and the connecting piece 7 and the rack 8 are both slidable. It is connected to the inside of the base 1, and the inside of the base 1 is rotatably connected with a differential gear 9, the rack 8 is meshed with one side of the surface of the differential gear 9, and the bottom end of the rack 8 is penetrated with the bottom of the base 1, and connecting arms 10 are symmetrically fixedly connected on both sides of the surface of the connecting piece 7. Positioning grooves 11 are symmetrically opened on both sides of the inside of the base 1, and the side of the positioning groove 11 away from the rack 8 is penetrated with the base 1. The connecting arm 10 is slidably connected to the base 1 through the positioning groove 11, and one end of the connecting arm 10 that penetrates to the outside of the base 1 is fixedly connected with a lower pressure block 12, and the lower pressure block 12 is located above the guide slope 2.

[0035] Among them, through the guiding effect of the guide slope 2, it can be ensured that the plate to be stamped can be smoothly placed on the top of the base 1. At this time, the part of the plate to be stamped will be located directly below the arc-shaped pressing groove 5. At this time, the cylinder 6 drives the rack 8 and the two connecting arms 10 to descend through the connecting plate 7. During the process of the connecting arm 10 descending along the positioning groove 11, it will drive the two lower pressing blocks 12 to gradually press down, and cooperate with the guide slope 2 to perform a stable clamping and fixing effect on the plate to be stamped, thereby ensuring the stability of the position of the plate and preventing the problem of shaking or deviation that is easy to occur in the hand-held fixed state. The upper press seat 3 is driven to descend by the telescopic rod 4, and the plate can be stamped and formed by the upper press seat 3, forcing the warped head on the surface of the plate after the pre-bending treatment to move in an arc shape along the inner wall of the arc-shaped pressing groove 5, thereby producing a stable curling work and ensuring the working effect of the stamping and forming.

[0036] A connecting tooth 13 is meshed with the other side of the surface of the differential tooth 9, and the diameter of the differential tooth 9 is larger than the diameter of the connecting tooth 13. A connecting groove 14 is opened inside the base 1, and the connecting tooth 13 is rotatably connected to the inside of the connecting groove 14. Two connecting screws 15 are symmetrically fixedly connected on both sides of the surface of the connecting tooth 13, and a connecting ring 16 is threadedly connected to the surface of the connecting screw 15. A connecting column 17 is rotatably connected to the other side of the connecting ring 16. The two connecting columns 17 are slidably connected to the two sides of the base 1 at one end away from the connecting tooth 13, and a connecting box 18 is rotatably connected to the end of the connecting column 17 that penetrates to the outside of the base 1. A positioning column 19 is rotatably connected to one side of the surface of the connecting box 18. The positioning column 19 is slidably connected to the top of the base 1 through the guide slope 2, and the positioning column 19 is located above the connecting column 17.

[0037] Among them, in the process of the cylinder 6 driving the connecting plate 7 to descend, the rack 8 will follow the decline and drive the differential gear 9 to rotate. Since the diameter of the differential gear 9 is larger than the diameter of the connecting tooth 13, the connecting tooth 13 will rotate relatively quickly at this time, and drive the two connecting screws 15 on both sides thereof to rotate synchronously. Due to the threaded connection effect between the connecting ring 16 and the connecting screw 15, the connecting ring 16 can drive the two connecting columns 17 to approach each other, which can drive the two positioning columns 19 to approach each other, and ensure that the two positioning columns 19 are located on the upper surface of the sheet to be stamped, thereby completing the core insertion processing of the rolling operation and further improving the working effect of the rolling forming.

[0038] The relatively close ends of the two connecting columns 17 are fixedly connected with guide teeth 20, and the two guide teeth 20 are located between the two connecting rings 16. The surfaces of the two guide teeth 20 away from the connecting teeth 13 are meshed with rotating teeth 21, and the rotating teeth 21 are rotatably connected to the inside of the base 1. The other side of the surface of the rotating teeth 21 is meshed with a toothed plate 22, and the top of the toothed plate 22 penetrates to the top of the base 1, and the end of the toothed plate 22 that penetrates to the top of the base 1 is fixedly connected to the bottom of the upper pressure seat 3. The interior of the connecting box 18 is rotatably connected with a connecting wheel 23, and one side of the surface of the connecting wheel 23 is fixedly connected to the connecting column 17. A positioning box 24 is slidably connected to the top of the connecting box 18, and a rotating wheel 25 is rotatably connected to the positioning box 24. A tensioning belt 26 is transmission-connected between the rotating wheel 25 and the connecting wheel 23, and the rotating wheel 25 is located above the connecting wheel 23, and one side of the surface of the rotating wheel 25 is fixedly connected to the positioning column 19.

[0039] Among them, when the upper pressure seat 3 is pressed down, the tooth plate 22 will be driven down, and the rotating gear 21 will be driven to rotate through the meshing effect. After the two connecting columns 17 slide close to each other, the two guide teeth 20 approach each other and mesh with one side of the guide tooth 20. At this time, the guide tooth 20 will rotate with the rotating gear 21, and the rotation of the connecting column 17 will drive the connecting wheel 23 to rotate. Through the transmission effect of the tensioning belt 26, the upper rotating wheel 25 can be driven to rotate, thereby driving the positioning column 19 to rotate. During the stamping and rolling forming process, the two positioning columns 19 can be forced to rotate at the center of the circle. On the one hand, the rolling forming effect is guaranteed, and on the other hand, the positioning column 19 is prevented from being bonded to the plate due to the large pressure during stamping.

[0040] Two positioning seats 27 are symmetrically and slidably connected on both sides of the base 1. A guide groove 28 is opened on the top of the positioning seat 27 near the upper pressure seat 3. The guide groove 28 is slidably connected to the positioning column 19. A top block 29 is fixedly connected to one side of the surface of the lower pressure block 12. The bottom of the top block 29 can be slidably connected to the top of the positioning seat 27. Connecting heads 30 are symmetrically and fixedly connected on both sides of the bottom of the positioning box 24. The bottom end of the connecting head 30 penetrates into the interior of the connecting box 18, and the connecting head 30 is slidably connected to the connecting box 18. One end of the connecting head 30 located inside the connecting box 18 is fixedly connected to a return spring 31, and the other end of the return spring 31 is fixedly connected to the interior of the connecting box 18. A slider 41 is fixedly connected to one side of the surface of the positioning seat 27. A top spring 42 is fixedly connected to the bottom of the slider 41, and the other end of the top spring 42 is fixedly connected to the interior of the base 1. The slider 41 is slidably connected to the surface of the base 1. Three balls 43 are rotatably connected to the inside of the guide groove 28, and the positioning column 19 is slidably connected to the guide groove 28 through the balls 43.

[0041] Among them, the descent of the connecting arm 10 will drive the top block 29 to descend. When the bottom end of the top block 29 contacts the top of the positioning seat 27, it will push the positioning seat 27 downward. At this time, the heights of the two positioning columns 19 on both sides will drop, which can ensure that after the lower pressure block 12 clamps the plate, the two positioning columns 19 can fit on the upper surface of the plate, ensuring that the curvature of the rolling forming remains consistent, ensuring the effect of the rolling work, and the guiding effect formed by the cooperation of the guide groove 28 and the ball 43 can ensure that the positioning column 19 can slide stably and smoothly to the top of the plate.

[0042] A connecting block 32 is provided between the connecting wheel 23 and the rotating wheel 25, and slots 33 are symmetrically provided on both sides of the interior of the positioning box 24. The connecting block 32 is slidably connected to the positioning box 24 through the slots 33, and the connecting block 32 is fixedly connected to the interior of the connecting box 18. A tensioning spring 34 is fixedly connected to one side of the surface of the connecting block 32, and the other end of the tensioning spring 34 is fixedly connected to a connecting frame 35. One end of the connecting frame 35 is slidably connected to both sides of the surface of the connecting block 32, and the other end of the connecting frame 35 is rotatably connected to a tensioning wheel 36. The tensioning wheel 36 is rotatably connected to the interior of the connecting box 18, and the tensioning wheel 36 is rotatably connected to the tensioning belt 26.

[0043] Among them, after the top block 29 is separated from the positioning seat 27, the positioning box 24 will slide up due to the elastic effect of the return spring 31, thereby driving the positioning column 19 to slide up, and the sliding effect between the connecting block 32 and the notch 33 can ensure that the positioning box 24 slides smoothly, and when the positioning column 19 and the rotating wheel 25 slide up, the distance between the rotating wheel 25 and the connecting wheel 23 becomes larger, and the length of the tensioning belt 26 between the two will also change accordingly. At this time, the tensioning wheel 36 will adaptively slide in the direction close to the connecting block 32 to ensure that the tensioning belt 26 can smoothly transmit the connecting wheel 23 and the rotating wheel 25, and after the distance between the connecting wheel 23 and the rotating wheel 25 becomes smaller, in order to ensure that the tensioning belt 26 is loose and slipping, the tensioning spring 34 will push the connecting frame 35 in the direction away from the connecting block 32, thereby ensuring that the tensioning wheel 36 can always keep the tensioning belt 26 in a tensioned state.

[0044] A linkage groove 37 is provided inside one of the connecting columns 17, and the end of the linkage groove 37 close to the rotating tooth 21 is penetrated by the connecting column 17. A linkage rod 38 is fixedly connected to the end of the other connecting column 17 close to the rotating tooth 21, and the linkage rod 38 is plugged into the linkage groove 37, and the linkage rod 38 and the linkage groove 37 can be snapped together. Two auxiliary grooves 39 are provided inside the connecting groove 14, and two auxiliary blocks 40 are slidably connected to the inside of the connecting groove 14 through the two auxiliary grooves 39, one of the auxiliary blocks 40 is fixedly connected to the top of one of the connecting rings 16, and the other auxiliary block 40 is fixedly connected to the bottom of the other connecting ring 16.

[0045] Among them, through the plug-in effect between the linkage groove 37 and the linkage rod 38, it can be ensured that the two connecting columns 17 can be smoothly docked, and there is a card-connection effect between the linkage rod 38 and the connecting groove 14, which can ensure a stable synchronous rotation effect between the two connecting columns 17, ensure the rotation effect of the positioning column 19, and further improve the overall working effect. Since the two connecting columns 17 are only subjected to force on one side when sliding, the sliding effect between the auxiliary block 40 and the auxiliary groove 39 can improve the stability of the connecting column 17 when sliding.

[0046] The specific working principle and method of use of the present invention are explained in detail below: when in use, in the first step, the guiding effect of the guide slope 2 can ensure that the plate to be stamped can be smoothly placed on the top of the base 1. At this time, the part of the plate to be stamped will be located directly below the arc-shaped pressing groove 5. At this time, the cylinder 6 drives the rack 8 and the two connecting arms 10 to descend through the connecting piece 7. During the process of the connecting arm 10 descending along the positioning groove 11, it will drive the two lower pressing blocks 12 to gradually press down, and cooperate with the guide slope 2 to perform a stable clamping and fixing effect on the plate to be stamped, so as to ensure the stability of the position of the plate and prevent the problem of shaking or deviation that is easy to occur in the hand-held fixed state. The upper pressing seat 3 is driven to descend by the telescopic rod 4, and the plate can be stamped and formed by the upper pressing seat 3, forcing the warped head on the surface of the plate after the pre-bending treatment to move in an arc along the inner wall of the arc-shaped pressing groove 5, thereby producing a stable curling work;

[0047] In the second step, when the cylinder 6 drives the connecting piece 7 to descend, the rack 8 will follow and descend and drive the differential gear 9 to rotate, and the two connecting screws 15 drive the two connecting columns 17 to approach each other, which can drive the two positioning columns 19 to approach each other, and ensure that the two positioning columns 19 are located on the upper surface of the sheet to be stamped, so as to complete the core insertion processing of the rolling operation and further improve the working effect of the rolling forming;

[0048] In the third step, when the upper pressure seat 3 is pressed down, the tooth plate 22 will be driven down, and the rotating gear 21 will be driven to rotate through the meshing effect. After the two connecting columns 17 slide close to each other, the two guide teeth 20 are close to each other and mesh with one side of the guide tooth 20. At this time, the guide tooth 20 will rotate with the rotating gear 21, and the rotation of the connecting column 17 will drive the connecting wheel 23 to rotate. Through the transmission effect of the tensioning belt 26, the upper rotating wheel 25 can be driven to rotate, thereby driving the positioning column 19 to rotate. In the process of stamping and rolling forming, the two positioning columns 19 can be forced to rotate at the center of the circle. On the one hand, the rolling forming effect is guaranteed, and on the other hand, the positioning column 19 is prevented from being bonded to the plate due to the large pressure during stamping.

[0049] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
