Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of automotive mold technology, and more specifically, to a trimming and punching mold. Background Technology
[0002] A mold is a specialized tool used for mass production of items, which completes product forming by giving materials specific shapes and sizes. Trimming and punching molds are a type of composite process mold in stamping molds, mainly used to trim the edges and punch holes of workpieces after metal sheets have been formed, so that they can achieve precise dimensions, shapes and functional requirements. In the automotive manufacturing industry, automotive molds, especially body panel molds, have extremely high requirements for trimming and punching precision, because this directly affects the appearance quality and assembly accuracy of automobiles.
[0003] Traditional trimming and punching dies have the following shortcomings: During use, if the diameter of the punching waste (D1) is close to the diameter of the blanking hole (D2) (e.g., D1 / D2≥0.8), the waste accumulation near the hole can easily form a "bridging effect" (waste pieces interlock, forming an arched structure), preventing subsequent waste from penetrating the accumulation layer. Alternatively, if the waste falls strictly vertically, the accumulation will be columnar. When the accumulation height (H) is close to the height of the blanking hole (H0), the waste may directly block the lower edge of the hole, causing blockage. Frequent cleaning of the waste is required. Therefore, improvements are needed. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a trimming and punching die, which solves the technical problem of waste accumulation in the related art.
[0005] According to one aspect, at least one embodiment of this disclosure provides a trimming and punching die, including a base plate, a template bolted to the top of the base plate, holes formed on the surface of the template, a punching waste groove formed on the surface of the base plate below the holes, the front end of the punching waste groove extending to the outside of the die, a collecting device provided inside the punching waste groove, the collecting device including a collecting plate slidably connected inside the punching waste groove, a collecting trough formed on the surface of the collecting plate below the holes, a rectangular plate welded inside the collecting trough, a disc rotatably mounted above the rectangular plate, a circular block welded above the disc, push plates slidably connected to both sides of the rectangular plate inside the collecting trough, a fixing block welded above each of the two push plates, a transmission plate one and a transmission plate two rotatably mounted on the outside of the circular block, the other ends of the transmission plate one and the transmission plate two rotatably mounted on the outside of the two fixing blocks respectively.

Therefore, they should not be construed as limitations on this disclosure.
[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0033] like Figures 1-8 The illustration shows a trimming and punching die according to an embodiment of the present disclosure, comprising a die 1, a base plate 11, a template 3 bolted to the top of the base plate 11, holes 4 formed on the surface of the template 3, and a punching waste trough 13 formed on the surface of the base plate 11 below the holes 4. The front end of the punching waste trough 13 extends to the outside of the die 1, and a collecting device 5 is provided inside the punching waste trough 13. The collecting device 5 includes a collecting plate 501 slidably connected inside the punching waste trough 13, and the surface of the collecting plate 501 is formed below the holes 4. The collection trough 503 is located below. A rectangular plate 504 is welded inside the collection trough 503. A disc 506 is rotatably mounted on the top of the rectangular plate 504. A circular block 507 is welded on the top of the disc 506. Push plates 514 located on both sides of the rectangular plate 504 are slidably connected inside the collection trough 503. A fixing block 515 is welded on the top of each of the two push plates 514. A transmission plate 1 508 and a transmission plate 2 509 are rotatably mounted on the outside of the circular block 507. The other ends of the transmission plate 1 508 and the transmission plate 2 509 are rotatably mounted on the outside of the fixing blocks 515 on both sides.
[0034] The bottom of the collecting plate 501 is bolted with a servo motor 513, the output end of which extends through to the top of the rectangular plate 504 and is bolted to the bottom of the disc 506. An arc-shaped groove 505 is provided on the top of the collecting plate 501, and the arc-shaped groove 505 matches the movement trajectory of the transmission plate 508 and the transmission plate 509. A pull plate 502 is welded to the front end of the collecting plate 501, and the pull plate 502 is located on the outside of the bottom plate 11. The distance between the push plate 514 and the rectangular plate 504 is equal during the punching process, and the rectangular plate 504 is located between the inner sides of the holes 4 at both ends in the vertical direction. The depth of the punching waste groove 13 is greater than the depth of the repair waste groove 12, and the length of the repair waste groove 12 is equal to the length of the template 3.
[0035] In some examples, after the punching operation is completed during the automotive mold manufacturing process, the punching waste falls into the collection tank 503. At this time, the servo motor 513 is activated, causing the disc 506 to rotate one revolution. This causes the block 507 to move in a circular motion above the disc 506, thereby causing the transmission plate 508 and the transmission plate 509 to move eccentrically inside the arc groove 505, pushing the push plate 514 back and forth. This push plate 514 pushes the punching waste that has fallen into the collection tank 503 through the hole 4 away from below the hole 4, so as not to affect the next punching operation.
[0036] By activating the servo motor 513, the disc 506 drives the transmission plate 508 and transmission plate 509 to perform eccentric motion via the block 507. This causes the push plate 514 to push the punching waste away from below the hole 4. Compared with traditional trimming punching dies, this trimming punching die uses the push plate 514 to move back and forth to push away the waste below the hole 4, thus not affecting the next punching operation and effectively preventing waste accumulation. It is especially suitable for high-frequency punching operations in automotive mold manufacturing, reducing the frequency of waste cleaning and making it easy to use.
[0037] like Figures 1-8 As shown, a trimming and punching die according to another embodiment of the present disclosure is illustrated. A platform 2 is welded to both sides of the base plate 11. A square groove 6 is provided on the outer side of the platform 2. A moving device 7 is provided inside the square groove 6. The moving device 7 includes a servo motor 71 bolted inside the square groove 6. A vertical groove 76 is provided below the square groove 6. The output end of the servo motor 71 is vertically downward and bolted with a lead screw 75. A mounting plate 72 is threaded onto the outer side of the lead screw 75. Moving wheels 73 are rotatably mounted on the inner sides of both ends of the mounting plate 72. A short plate 74 is welded to the bottom of the vertical groove 76. The other end of the lead screw 75 is rotatably connected to the top of the short plate 74.
[0038] In some examples, when it is necessary to transfer mold 1, servo motor 2 71 is first started, which drives lead screw 75 to rotate. Lead screw 75 drives mounting plate 72 to move downward under the limit of vertical groove 76. Mounting plate 72 drives moving wheel 73 to move downward, so that moving wheel 73 contacts the ground. At this time, push platform 2, so that moving wheel 73 rotates and drives mold 1 to move, thereby facilitating the transfer of mold 1.
[0039] like Figures 1-3 As shown, a trimming and punching die is provided in another embodiment of the present disclosure. Repair waste grooves 12 are provided on the upper sides of both sides of the base plate 11, and waste boxes 8 are provided inside the repair waste grooves 12.
[0040] In some examples, trimming waste is collected into the waste box 8 by repairing the waste trough 12, and then the waste box 8 is removed to clean up the trimming waste.
[0041] like Figure 6 As shown, a trimming and punching die is provided in another embodiment of the present disclosure. A groove 510 is provided below the collecting plate 501. A bottom block 511 is uniformly welded to the bottom of the groove 510. Rollers 512 are rotatably installed on both sides of the bottom block 511.
[0042] In some examples, when the pull plate 502 is pulled, the roller 512 rotates inside the punching waste trough 13, thereby reducing the friction between the collection plate 501 and the punching waste trough 13, making it easier to pull out the collection plate 501.
[0043] Working principle and usage process of this utility model:
[0044] After the punching operation is completed in the automotive mold manufacturing process, the punching waste falls into the collection tank 503. As the core equipment for the production of body panel parts, the punching accuracy of the automotive mold directly affects the assembly quality of key components such as doors and hoods. At this time, the servo motor 513 is activated, which drives the disc 506 to rotate one revolution. This causes the block 507 to move in a circular motion above the disc 506, thereby driving the transmission plate 508 and the transmission plate 509 to move eccentrically inside the arc groove 505, pushing the push plate 514 back and forth. This design is particularly suitable for the continuous punching of high-strength steel plates in automotive molds, and can effectively solve the problem of punch wear caused by the accumulation of waste in traditional molds. The push plate 514 pushes the punching waste that falls into the collection tank 503 through the hole 4, pushing the waste away from below the hole 4, thereby ensuring that the waste is removed in time after each punching and avoiding hole deformation caused by waste rebound.
[0045] When mold 1 needs to be transferred, servo motor 71 is first started, causing the lead screw 75 to rotate. Automotive molds are typically heavy, and traditional handling methods can easily damage the positioning reference. The lead screw 75 then drives the mounting plate 72 downwards under the limit of the vertical groove 76. This causes the mounting plate 72 to drive the moving wheels 73 downwards, bringing them into contact with the ground. The moving wheels 73 are polyurethane-coated, which can support the weight of the mold while preventing scratches on the workshop floor. At this point, pushing the platform 2 allows for mold transfer, which is particularly suitable for the rapid transfer of automotive molds between the trial molding area and the production line. After transfer, the mold installation and repositioning accuracy error is small, meeting the high requirements of automotive manufacturing for repeated mold positioning.
