DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figures 1 to 6As shown, a specific embodiment of the present invention discloses a button metal cover stamping die, comprising: an upper die 100; a lower die 200, wherein the lower die 200 is provided with a first channel 211, a second channel 212, and a third channel 213 arranged in layers from top to bottom, the first channel and the third channel extend along the length direction of the lower die, and the second channel extends along the width direction of the lower die; the lower die 200 is provided with a first punching hole 214 at the intersection of the first channel 211 and the second channel 212, and a blanking hole 215 corresponding to the intersection of the second channel 212 and the third channel 213; the third A discharge port 216 for discharging materials is provided at the bottom of the channel 213; a push structure 300 is used to push the workpiece at the first punching hole 214 toward the blanking hole 215; a drag structure 400 is used to drive the workpiece at the blanking hole 215 to move toward the discharge port 216; and drive the material belt passing through the first channel to move forward a fixed distance; a cutting mechanism 500 is used to cut the waste after punching; the push structure 300 and the drag structure 400 adapt to the movement of the lifting and lowering movement of the upper mold 100, and the cutting mechanism 500 is driven by the drag structure 400 that has moved into place.

[0035] The above-mentioned button metal cover stamping die has a plurality of channels designed and matched, so that the first stamping part, the second stamping part and the material discharge part are staggered, so that the workpiece and the waste can be sent out separately, especially convenient for collecting the workpiece and preventing it from flying away at will;

[0036] The push structure, the drag structure and the cutting mechanism can realize the displacement of the workpiece after stamping, the fixed-distance movement of the material strip and the cutting of the waste material. There is no need to install an additional independent feeding structure and cutting structure, which also omits the complicated debugging and assembly, which can effectively reduce costs and improve efficiency. The overall structure is compact, which reduces the external space occupation.

[0037] In addition, the push structure and the drag structure adapt to the movement of the upper mold. The cutting mechanism is driven by the drag structure that has moved into place. The action of the stamping equipment to drive the upper mold to move is used as the driving force, which promotes the linkage and coordination of the entire structure. No additional electric drive components are required, which effectively reduces equipment and operating costs and improves overall efficiency.

[0038] Further, the lower die 200 includes a first support plate 221, a second support plate 222, and a third support plate 223 stacked in sequence from top to bottom; the first channel 211 is provided on the bottom surface of the first support plate 221, and the first punching hole corresponds to the intersection of the first channel and the second channel and penetrates the first support plate; the second channel 212 is provided on the top surface of the second support plate 222, and the blanking hole corresponds to the intersection of the second channel and the third channel and penetrates the second support plate; the third channel 213 is provided on the top surface of the third support plate 223, and the discharge ports are correspondingly provided on both sides of the blanking port and penetrate the third support plate; the stacked assembly structure is adopted, which can facilitate the design and processing of various structural components, and also facilitate the disassembly, assembly and replacement of parts, and the overall assembly is relatively simple and convenient to operate;

[0039] One end of the first support plate 221 extends beyond the end surface of the second support plate 222, and the cutting mechanism 500 is installed at the protruding portion of the first support plate 221 so that it falls outside the output end of the first channel, and is used to cut the end of the waste output from the first channel 211, thereby realizing the action of linkage cutting without the need for additional cutting devices;

[0040] Among them, the stacked first support plate, the second support plate, and the third support plate are fixedly connected by bolts to fit tightly, so that the corresponding channels maintain the required size; further, the lower mold and the upper mold are also provided with holes for installing the guide mechanism, and the cooperation between the upper mold and the lower mold can be further limited by adding the guide mechanism, so that the operation of each structural component is coordinated; it should be pointed out that in order to facilitate the display of core components, the guide mechanism is not illustrated in this application;

[0041] Furthermore, if Figure 5 , Figure 6As shown, the push structure 300 includes a first push frame 310 and a first tension spring 320; the first push frame 310 includes a first push plate 311, the insertion end of the first push plate 311 is provided with a first bayonet 312 adapted to the shape of the workpiece, and the top surface of the other end is fixedly provided with a first inclined guide block 313, and the first push plate 311 is slidably inserted in the second channel 212; first pull rods 314 are installed on both sides of the end of the first push frame 310 away from the first bayonet, one end of the first tension spring 320 is hooked on the first pull rod 314, and the other end is hooked on the second support plate 222, and the two first tension springs provide the first push frame with a pulling force to move inward, so that the first bayonet moves to align with the second stamping part; the upper die 100 The first roller 110 is installed on the side wall corresponding to the first inclined guide block 313. When the upper mold moves downward, the first roller applies force to the first inclined guide block, so that the first push frame overcomes the elastic force of the first tension spring and moves outward until the first bayonet moves to the position corresponding to the first punching hole. This structural design utilizes the downward movement of the upper mold and achieves force dispersion and transfer through the cooperation between the first roller and the first inclined guide block, thereby pushing the first push frame outward. When the upper mold moves upward, the force applied to the first inclined guide block is released, and the first push frame moves back under the action of the first tension spring, thereby realizing the reciprocating movement of the first push frame as the upper mold moves up and down, and there is no need to add an additional electric drive device to the push structure, thereby reducing equipment and operating costs.

[0042] The cam is provided with a first guide hole, and the first guide hole is provided at the bottom of the cam, and the first guide hole is provided at the bottom of the cam, so that the cam can slide smoothly.

[0043] It should be noted that the depth of the first guide hole is adapted to the reset stroke of the push structure, and the limit position of the inward movement of the push structure is limited by limiting the movement of the first guide rod, which is convenient for the alignment installation and motion trajectory design of other structural components. For example, when the first push frame moves inward to the closed end of the first guide hole where the first guide rod abuts and cannot move further, the first bayonet is aligned with the second stamping part at this time; and the workpiece at the first bayonet pushes the previous workpiece just to the blanking hole, thereby realizing the replacement and transfer of the workpiece;

[0044] Furthermore, if Figure 7 , Figure 8 As shown, the dragging structure 400 includes a second push frame 410, a second tension spring 420, and a hooking and pulling assembly 430; the second push frame 410 includes a second push plate 411, and a plurality of evenly spaced perforations 412 are provided on the second push plate 411, the aperture of the perforations is adapted to the diameter of the workpiece, and the spacing between two adjacent perforations is adapted to the moving distance of the material strip; the second push plate 411 is slidably inserted in the third channel 213, and a second inclined guide block 413 is fixedly provided on the top surface of the second push plate 411 away from the insertion end; second pull rods 414 are installed on both sides of the end of the second push frame 410 away from the insertion end, one end of the second tension spring 420 is hooked on the second pull rod 414, and the other end is hooked on the third support plate 223, and the two second tension springs provide the second push frame with an inward movement. The pulling force causes the perforation to move to align with the blanking hole; a support plate 415 is fixedly provided on the side of the second push frame 410 close to the first channel, and the support plate 415 extends to the bottom of the protruding end of the first support plate 221. The hook-pull assembly 430 is installed on the support plate 415 and falls on the extension line of the first channel 211; the side wall of the upper mold 100 is installed with a second roller 120 corresponding to the second inclined guide block 413. When the upper mold moves downward, the second roller applies force to the second inclined guide block, so that the second push frame overcomes the elastic force of the second tension spring and moves outward, and drags the material strip at a fixed distance through the hook-pull assembly; a push piece 416 is provided on the support plate 415 corresponding to the cutting mechanism 500. When the dragging structure is reset to the preset position, the push piece is used to drive the cutting mechanism to cut the waste at the end of the material strip;

[0045] This structural design utilizes the downward movement of the upper mold, and achieves force dispersion and transfer through the cooperation between the second roller and the second inclined guide block, thereby pushing the second push frame outward; and when the upper mold moves up, the force on the second inclined guide block is released, and the second push frame moves back under the action of the second tension spring, thereby realizing the reciprocating movement of the second push frame with the up and down movement of the upper mold, without the need to additionally provide an electric drive device for the push structure, thereby reducing equipment and operating costs; wherein, when the hook and pull component moves forward with the second push frame, it can drive the material belt to move forward, and when it moves back with the second push frame, it will not cause a dragging effect on the material belt, conforming to the fixed-distance movement requirements of the material belt, and adapting to the movement trajectory of the second push frame; correspondingly, the push member also moves with the second push frame, and only when the second push frame reciprocates and returns to the preset position will it drive the cutting mechanism to move, and complete the cutting when the material belt is in a stationary state, and there will be no interference with the dragging movement of the material belt, thereby maintaining the coordination of the overall movement;

[0046] The cam is provided with a second guide hole, and the second guide hole is provided on the second support plate so as to enable the cam to slide and slide back and forth, thereby preventing the cam from sliding back and forth and causing the cam to slide back and forth.

[0047] It should be noted that the depth of the second guide hole is adapted to the reset stroke of the dragging structure, and the limit position of the inward movement of the dragging structure is limited by the limited movement of the second guide rod, which is convenient for the alignment installation and motion trajectory design of other structural components. For example, when the second push frame moves inward to the closed end of the second guide hole against which the second guide rod abuts and cannot move further, the hook and pull assembly at this time just moves to the punching hole position of the material strip and is close to the side of the hole position away from the first channel to prepare for the subsequent dragging of the material strip; and the perforation position on the second push plate corresponds to the position of the blanking hole, so that the workpiece falls smoothly into the perforation position, which is convenient for subsequent material discharge; in addition, the push member is just in the position of the push-pushing cutting mechanism, prompting the cutting mechanism to cut the waste at the end of the material strip;

[0048] Furthermore, a sink groove 417 is provided on the top surface of the support plate 415, and the sink groove 417 falls on the extension line of the first channel 211; the hook-pull assembly 430 includes a rotating shaft 431, a torsion spring 432, and a hook member 433; the hook member 433 includes a support ring 4331, and the outer wall of the support ring 4331 is fixedly provided with a retaining strip 4332 extending in the radial direction; the support ring 4331 is rotatably installed at the sink groove 417 through the rotating shaft 431, and the torsion spring 432 is sleeved on the rotating shaft 431, and the two end surfaces of the support ring and the two groove walls of the sink groove are provided with a clamping position corresponding to the torsion spring, which is used to clamp the end clamping strip of the torsion spring, so that the torsion spring conforms to the swinging direction required by the hook member, and provides the hook member with an elastic force to twist in the direction of the first channel; the outer wall of the support ring 4331 is provided with There is a straight part; when the second push rack moves outward, the hook is twisted in the direction of the first channel by force until the straight part is against the groove wall of the sink groove, and the baffle maintains an upright position, and its top end extends into the punched hole of the material belt, so that the material belt moves with the second push rack; when the second push rack moves inward, the hook is twisted in the direction of the sink groove by force, and the baffle is separated from the punched hole of the material belt, and the material belt does not move with it; this structural design can limit the rotation of the hook, so that the baffle maintains an upright state when the second push rack moves outward, thereby effectively dragging and moving the material belt; when the baffle moves back when the second push rack, it can swing without causing a dragging effect on the material belt, thereby achieving the goal that the second push rack will drive the material belt to move a fixed distance when it moves outward.

[0049] Furthermore, if Fig. 9 , Fig.10 As shown, one end of the first support plate 221 close to the dragging structure extends outward to form an extension portion 2211, and the bottom surface of the extension portion 2211 is flush with the top surface of the first channel 211; a jacket 2212 is fixedly provided at the end of the extension portion 2211, and the internal shape of the jacket 2212 is adapted to the shape of the first channel 211, and the positions correspond; the material strip passing through the first channel is passed through the jacket, and the material strip slides against the bottom surface of the extension portion; the jacket and the extension portion can limit and support the movement of the material strip, and can prevent the material strip from being too soft or even bending and hanging down after punching, so as to avoid affecting the normal dragging and conveying action; the cutting mechanism 500 is installed at the jacket 2212 to cut the material strip in the jacket, and there is enough space between this position and the output port of the first channel, which does not affect the fixed-distance dragging movement of the material strip by the dragging structure, and can also cut the waste material at the end;

[0050] The top of the baffle is spherical, and the bottom surface of the extension is provided with a groove extending along the length direction. The position of the groove corresponds to the position of the baffle, and the shape is adapted. The provided groove can provide a place for accommodating the top of the baffle, so that when the baffle is placed upright, the top of the baffle is higher than the material belt, which can better achieve the push-pull effect on the material belt.

[0051] Furthermore, the cutting mechanism 500 includes a cutter 510, and guide bolts 520 are installed on the top surfaces of both ends of the cutter 510; a guide groove 2213 is provided on the bottom surface of the jacket 2212, and the guide groove extends along the width direction of the jacket and passes through the inner two sides of the jacket; the top surface of the guide groove is higher than the top surface of the first channel; third guide holes 2214 are provided at both ends of the guide groove 2213, which pass through the top surface of the jacket 2212, and the guide bolts 520 are inserted in the third guide holes 2214. The cutter 510 is installed at the guide groove 2213, and the blade is set upward; when the second push frame is reset inward to a preset position, the position of the push member corresponds to the position of the cutter, which is used to push the cutter upward so that the cutter cuts the material strip; the structure of the entire cutting mechanism is simple, and the cutting action and reset adjustment are realized by lifting and lowering activities, and the cutting action is performed when the second push frame moves back, and the material strip is in a stationary state at this time, which can ensure cutting and segmentation, and also prevent the problem of collision damage of structural components due to action interference;

[0052] Furthermore, the bottom of the cutter is in an outward convex arc shape, the top of the push piece is in an outward convex arc shape, and the two sides of the push piece transition to the arc of the top surface of the support plate, so that it can be smoothly tilted and pushed to the cutter, so that the cutter cuts the material strip;

[0053] Furthermore, the dragging structure is used to drive the fixed-distance dragging material strip to move, and the position of the cutter is aligned with the center of the punching hole of the material strip in the jacket. The area required for cutting at this position is the smallest, which can facilitate cutting and segmentation and ensure the cutting effect.

[0054] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
