Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a hardware stamping die with automatic edge trimming function. Background Technology

[0002] Utility model patent application CN219746069U discloses an automatic edge-cutting metal stamping die, including a metal stamping die body, an impact die arranged at the top center of the metal stamping die body, cutting tools arranged on both sides below the impact die, a support plate arranged at the top center of the metal stamping die body, a centering mechanism arranged at the rear side of the metal stamping die body, and an elastic mechanism arranged at the front side of the centering mechanism. The elastic mechanism is used to move to the underside of the support plate. Discharge ports are arranged inside both sides of the metal stamping die body. This utility model patent solves the problem of automatically removing edge material. The previous process required operators to stop the machine and remove the scrap material for safety, which involved turning the machine off and on again, making it very cumbersome. A new type of metal stamping die that automatically cuts off scrap material includes a main body and an impact die positioned at the top center of the main body. This allows an elastic mechanism to move into the interior of a support plate. When the impact die resets, it drives the elastic mechanism back to its original position, pushing the cut scrap material outwards to the discharge port. This eliminates the need for manual machine stopping for cleaning, thus solving the problem of the cumbersome process.

[0003] After the existing stamping die is punched, the scrap material and the stamped product will be on the surface of the lower die. The scrap material and the stamped product need to be manually removed and sorted, which is not only troublesome but also requires labor costs. At the same time, the existing stamping requires manual placement of the workpiece on the lower die for alignment. To maximize the utilization of the workpiece, the scrap material needs to be aligned as accurately as possible to avoid stamping defects. Therefore, it consumes a lot of manual labor.

[0004] Therefore, this utility model designs a metal stamping die with automatic edge trimming function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a metal stamping die with an automatic edge trimming function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hardware stamping die with automatic edge trimming function, including a support frame, the two ends of the support frame being connected to a base, a lower template being provided on the surface of the base, an upper template being provided on the upper end of the lower template, the upper template being connected to the output end of a hydraulic cylinder, the hydraulic cylinder being connected to the middle position of the support frame, and a sorting and positioning device being provided on the surface of the lower template.

[0007] Furthermore, the sorting and positioning device includes symmetrically arranged sorting rods, which are connected to an electric push rod.

[0008] Furthermore, the two sorting rods are threadedly connected to a bidirectional screw, and an anti-rotation rod is provided at the bottom of the sorting rod. The anti-rotation rod is slidably connected to the output end of the electric push rod, and the middle position of the bidirectional screw is rotatably engaged with the output end of the electric push rod.

[0009] Furthermore, the sorting rod has a sliding groove, which is connected to the positioning block.

[0010] Furthermore, the top of the positioning block is connected to a positioning nut, and the positioning nut is threadedly connected to a positioning bolt.

[0011] Furthermore, the positioning block includes a positioning sleeve, the bottom of which is connected to a second elastic element, the other end of which is connected to the positioning block, and the end of the positioning block away from the second elastic element is arc-shaped.

[0012] Furthermore, the lower template is slidably connected to the anti-detachment ejection structure, which includes a top plate. The top plate is slidably connected to the lower template. The bottom of the top plate is connected to a section of a slide rod, and the other end of the slide rod is slidably connected to a threaded sleeve. A first elastic element is provided at the bottom of the slide rod. The bottom of the threaded sleeve is connected to one end of the linkage frame, and the other end of the linkage frame is connected to the output end of the hydraulic cylinder. A position sensor is provided in the hydraulic cylinder.

[0013] Furthermore, collection frames are symmetrically arranged on both sides of the lower template, and the collection frames are slidably connected to both sides of the lower template.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the hardware stamping die with automatic edge trimming function is reasonable and has the following advantages:

[0015] (1) While the hydraulic cylinder drives the upper template to press the workpiece, the linkage frame will move down through the output end of the hydraulic cylinder. At the same time, the linkage frame will move the top plate down. The workpiece under pressing will be transferred into the top plate. When the output end of the hydraulic cylinder is controlled by the position sensor to retract a certain distance for the first time, so that the upper template is higher than the sorting rod, the sorting rod is driven by the electric push rod to send the stamped edge material to one of the collection boxes. The output end of the hydraulic rod is controlled by the position sensor again to retract a certain distance for the second time, and the stamped workpiece is exposed to the lower template. The sorting rod is driven by the electric push rod again to sort the stamped workpiece into another collection box to complete the collection. At the same time, through the sliding rod, the first elastic element and the two ends of the top plate are arc surfaces. When the sorting rod contacts the two ends of the top plate which are arc surfaces, the top plate moves down under the influence of the first elastic element and the sliding rod, so as not to stop the sorting rod from moving and pushing the stamped workpiece to be sorted, thereby realizing automatic collection.

[0016] (2) When facing workpieces, it is necessary to maximize utilization and ensure that the edge material is accurately aligned to avoid defects in workpiece stamping. By rotating the bidirectional screw, the sorting rod can be moved inward or outward to limit the left and right positions of workpieces of different sizes. The positioning block can limit the front and back positions of the workpiece, thereby avoiding defects in stamping and improving workpiece utilization.

[0017] (3) The end of the positioning block away from the second elastic element is arc-shaped. Through the second elastic element and the positioning block with the arc-shaped end, the positioning block is pushed into the positioning block by the contraction of the second elastic element, which provides convenience for subsequent manual or mechanical pushing of the workpiece, and is more convenient and faster.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The technical solution provided by this utility model is as follows: A hardware stamping die with automatic edge trimming function includes a support frame 1, the two ends of the support frame 1 are connected to the base 2, the surface of the base 2 is provided with a lower template 5, the upper end of the lower template 5 is correspondingly provided with an upper template 4, the upper template 4 is connected to the output end of a hydraulic cylinder 3, the hydraulic cylinder 3 is connected to the middle position of the support frame 1, the surface of the lower template 5 is provided with a sorting and positioning device 8, and the two sides of the lower template 5 are symmetrically provided with collection frames 9, which are slidably connected to the two sides of the lower template 5.

[0027] The sorting and positioning device 8 includes symmetrically arranged sorting rods 81, which are connected to electric push rods 82. By pushing the sorting rods 81 with the electric push rods 82, the stamped workpieces and scrap materials can be sent to two collection boxes 9 for sorting.

[0028] Two sorting rods 81 are threadedly connected to a bidirectional screw 83. An anti-rotation rod 84 is provided at the bottom of the sorting rod 81. The anti-rotation rod 84 is slidably connected to the output end of the electric push rod 82. The middle position of the bidirectional screw 83 is rotatably engaged with the output end of the electric push rod 82. The sorting rod 81 has a sliding groove, which is connected to a positioning block 85. To maximize the utilization of the workpiece, the edge material should be accurately aligned to avoid defects in the workpiece stamping. By rotating the bidirectional screw 83, the sorting rod 81 can be moved inward or outward to limit the left and right positions of workpieces of different sizes. The positioning block 85 can limit the front and back positions of the workpiece, thereby avoiding stamping defects and improving the utilization rate of the workpiece.

[0029] The top of the positioning block 85 is connected to the positioning nut 87, and the positioning nut 87 is threadedly connected to the positioning bolt 86. The positioning block 85 can slide on the slide groove and be limited at the same time through the nut 87 and the positioning bolt 86, so that it can be limited for workpieces of different sizes and improve the fault tolerance rate of the limit.

[0030] The positioning block 85 includes a positioning sleeve 851. The bottom of the positioning sleeve 851 is connected to the second elastic member 852. The other end of the second elastic member 852 is connected to the positioning block 853. The end of the positioning block 853 away from the second elastic member 852 is arc-shaped. Through the second elastic member 852 and the positioning block 853 with the arc-shaped end, the positioning block 853 can push the workpiece into the positioning block 853 for limiting and locking by the contraction of the second elastic member 852, which provides convenience for subsequent manual or mechanical pushing of the workpiece, and is more convenient and faster.

[0031] The lower template 5 is slidably connected to the anti-detachment ejection structure 6. The anti-detachment ejection structure 6 includes a top plate 64, and both ends of the top plate 64 are arc surfaces. The top plate 64 is slidably connected to the lower template 5. The bottom of the top plate 64 is connected to a section of the slide rod 63, and the other end of the slide rod 63 is slidably connected to a threaded sleeve 61. A first elastic element 62 is provided at the bottom of the slide rod 63. The bottom of the threaded sleeve 61 is connected to one end of the linkage frame 7, and the other end of the linkage frame 7 is connected to the output end of the hydraulic cylinder 3. The hydraulic cylinder 3 is equipped with a position sensor. While the hydraulic cylinder 3 drives the upper template 4 to press the workpiece, the linkage frame 7 will be driven to move downward through the output end of the hydraulic cylinder 3. At the same time, the linkage frame 7 drives the top plate 64 to move downward, and the pressed workpiece will be transferred onto the top plate 64. When the output end of the hydraulic cylinder 3... When the upper template 4 is raised above the sorting rod 81 due to the position sensor's control, the sorting rod 81 is driven by the electric push rod 82 to send the stamped edge material to one of the collection boxes 9. The hydraulic rod 3 is then retracted a second time by the position sensor, exposing the stamped workpiece to the lower template 5. The sorting rod 81 is then driven by the electric push rod 82 again to sort the stamped workpiece into another collection box 9 for collection. Simultaneously, the sorting rod 81 contacts the top plate 64, which has curved ends, via the sliding rod 63, the first elastic element 62, and the top plate 64. When the sorting rod 81 contacts the top plate 64, the top plate 64 moves downward due to the influence of the first elastic element 62 and the sliding rod 63, thus not preventing the sorting rod 81 from moving and pushing the stamped workpiece to be sorted.
