DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides a stamping die waste separation mechanism, which can solve the problem in the related art that the shape of the scraps after stamping by the side punching die may be curved, which easily leads to the waste being difficult to discharge, and after long-term use, the scraps after side punching are easy to be blocked inside the waste port.

[0032] See also Figure 1-Figure 3A stamping die waste separation mechanism comprises: a lower die 1, a driving mechanism 3, a separation mechanism 4 and an upper die 7, wherein the lower die 1 is provided with a slag discharge port 2 for waste discharge; the driving mechanism 3 is slidably arranged on the lower die 1; the driving mechanism 3 comprises a punch fixing plate 31, a side punch pad plate 32, a driving block 33 and a group of springs 34, wherein the driving block 33 is slidably arranged on the lower die 1, the side punch pad plate 32 is arranged on the side wall of the driving block 33, a group of springs 34 is rectangularly embedded and arranged on one side of the side punch pad plate 32 close to the slag discharge port 2, and the punch fixing plate 31 is arranged between the other ends of a group of springs 34; wherein a group of springs 34 is four in number, and the four springs 34 include two nitrogen Spring and two compression springs, the separation mechanism 4 is arranged on the side punch pad 32; the separation mechanism 4 includes a side cutting edge 41, a side cutting punch 42, a side pressure plate 43 and a cutting head 44, the side cutting edge 41, the side cutting punch 42 and the side pressure plate 43 are embedded in the side punch pad 32 from top to bottom in sequence, the other ends of the side cutting edge 41, the side cutting punch 42 and the side pressure plate 43 all penetrate the punch fixing plate 31 and extend to the outside of the punch fixing plate 31, the cutting head 44 is arranged on the punch fixing plate 31; the cutting head 44 is provided with a square hole 1a for the sliding of the side cutting punch 42, the cutting head 44 is located on the front of the side cutting punch 42, and the upper mold 7 is provided with an inclined wedge 8 for squeezing the driving block 33 close to the slag discharge port 2.

[0033] It should be noted that the slag discharge port 2 is open on one side and at the bottom close to the driving mechanism 3, and the size of the slag discharge port 2 is adapted to the combined shape of the blade head 44, the side cutting edge 41 and the side pressure plate 43, so that the blade head 44, the side cutting edge 41 and the side pressure plate 43 can smoothly extend to the interior of the slag discharge port 2.

[0034] In actual use, the upper die 7 moves downward to cooperate with the lower die 1 to stamp and form the automobile parts. At the same time, the inclined wedge 8 squeezes the driving block 33, so that the driving block 33 moves to the side close to the slag discharge port 2, thereby driving the punch fixing plate 31 and the side punch pad 32 to approach the slag discharge port 2. When the punch fixing plate 31 contacts the slag discharge port 2, the edge and corner waste is side-cut by the blade head 44.

[0035] At the same time, the side punch pad 32 squeezes the spring 1 34, and the side punch pad 32 continues to move toward the side close to the slag discharge port 2, thereby driving the side cutting edge 41 and the side pressure plate 43 to extend outward inside the punch fixing plate 31 to squeeze and side cut the scraps. At the same time, the side cutting punch 42 extends to the outside of the square hole 1a to side cut the scraps, and the segmented scraps are discharged through the slag discharge port 2.

[0036] Through the above operation, the scraps after stamping can be side-cut multiple times, and the curved scraps can be divided into multiple sections, so that the scraps can be quickly discharged through the slag discharge port and separated from the side punching die, effectively preventing the scraps from being blocked inside the slag discharge port, avoiding the accumulation of scraps and causing damage to the die, and ensuring the production quality and efficiency of the products.

[0037] like Figure 4 and Figure 5 As shown, in this embodiment, three sliding holes 6 are sequentially opened on the punch fixing plate 31 from top to bottom, and the three sliding holes 6 are respectively adapted to the side cutting edge 41, the side cutting punch 42 and the side pressure plate 43; the side punch pad 32 is provided with three mounting grooves, and the side cutting edge 41, the side cutting punch 42 and one end of the side pressure plate 43 are sequentially embedded in the corresponding mounting grooves.

[0038] The side cutting blade 41, the side cutting punch 42 and the side pressure plate 43 can be installed and fixed respectively through the three installation grooves, and the side cutting blade 41, the side cutting punch 42 and the side pressure plate 43 can slide inside the punch fixing plate 31 respectively through the three sliding holes 6.

[0039] Specifically, Figure 4 and Figure 5 As shown, the driving block 33 in this embodiment includes an inclined block 331, a slide rail 332, a group of guide blocks 333 and a group of cross plates 334. The slide rail 332 is arranged on the lower mold 1, the inclined block 331 is slidably arranged inside the slide rail 332, a group of guide blocks 333 are relatively arranged above the slide rail 332, and a group of cross plates 334 are relatively arranged on both sides of the inclined block 331. The guide blocks 333 are in contact with the corresponding cross plates 334 and are used to guide the inclined block 331 to move along the length of the slide rail 332; the inclined block 331 is adapted to the inclined wedge 8, and the inclined wedge 8 is located directly above the inclined block 331, and the inclined block 331 and the inclined wedge 8 are both trapezoidal.

[0040] The slide rail 332 is hollow inside, and its top and the side close to the slag discharge port 2 are both open.

[0041] When the inclined wedge 8 squeezes the inclined block 331, since the inclined block 331 and the inclined wedge 8 are both trapezoidal and fit each other, the inclined wedge 8 drives the inclined block 331 to slide on the slide rail 332, so that the inclined block 331 approaches the slag discharge port 2, and limits the cross plate 334 by the guide block 333, so as to guide the moving trajectory of the inclined block 331 and allow the separation mechanism 4 to accurately enter the slag discharge port 2.

[0042] Preferably, Figure 4 , Figure 6 and Figure 7As shown, after the stamping is completed, in order to restore the inclined block 331 to its original position, the present embodiment further includes a reset mechanism 5, which is arranged on the inclined block 331;

[0043] The reset mechanism 5 includes a group of springs 51 and a mounting plate 52. A groove 332a is opened inside the slide rail 332. The mounting plate 52 is arranged at the lower end of the inclined block 331. The bottom end of the mounting plate 52 extends into the groove 332a. A group of springs 51 are relatively arranged on the mounting plate 52. The other end of the spring 51 abuts against the side wall of the groove 332a.

[0044] In actual use, when the upper die 7 is close to the lower die 1 to stamp the product, the inclined wedge 8 squeezes the inclined block 331, and the inclined block 331 moves to the side close to the slag discharge port 2, while driving the mounting plate 52 to compress the spring 2 51;

[0045] After the stamping is completed, the upper mold 7 is separated from the lower mold 1, the inclined wedge 8 moves away from the inclined block 331, the pressure on the inclined block 331 disappears, and the spring 1 34 returns to its natural state, so that the side punch pad 32, the side cutting edge 41, the side cutting punch 42, and the side pressure plate 43 return to their initial positions. At the same time, the spring 2 51 returns to its natural state, driving the inclined block 331 away from the slag discharge port 2 to return to its original position.

[0046] like Figure 4 As shown, in this embodiment, a partition plate 9 is provided inside the slag discharge port 2. It should be noted that the top of the partition plate 9 and the bottom of the blade head 44 are located at the same level.

[0047] When the cutting head 44 extends to the inside of the slag discharge port 2 to cut the scraps, the bottom of the cutting head 44 contacts the top of the partition plate 9 .

[0048] After multiple side cuts are made on the scraps, the slag discharge port 2 is separated into two channels by the partition 9 inside the slag discharge port 2, so that part of the scraps divided into multiple sections directly passes through the channel and falls down, and the other part falls down from another channel, avoiding interference between the divided waste materials and allowing the waste materials to be quickly discharged from the inside of the slag discharge port 2.

[0049] As a preferred embodiment, Figure 4 As shown, in this embodiment, a slope structure 10 is provided on the side of the slag discharge port 2 opposite to the cutting head 44 .

[0050] During actual operation, when the side cutting edge 41, the side pressure plate 43 and the side cutting punch 42 extend outward inside the punch fixing plate 31 to extrude and side-cut the scraps, the other side of the scraps contacts the inclined surface structure 10, so that both sides of the scraps are subjected to force at the same time. Through the pressure applied by the side cutting edge 41, the side pressure plate 43 and the side cutting punch 42, the other side of the scraps is squeezed and deformed at the inclined surface structure 10, which acts as a waste crusher. After the side cutting is completed, the waste hits the inclined surface structure 10 and is automatically discharged downward.
