Detailed Implementation
[0019] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0020] Please see Figures 1 to 3 This invention discloses a modular automatic feeding and automatic receiving stamping die. As shown in the figure, a preferred embodiment includes a die holder 1, an upper die frame 2, a feeding unit, a stamping unit, a feeding unit, a cutting unit, a receiving unit, a lower die frame 13, and die feet 14.
[0021] The upper die holder 2 is connected to the die shank 1, the top of which is connected to the upper mounting surface of the press. Similarly, the lower die holder 13 is connected to the die foot 14, the bottom of which is connected to the lower mounting surface of the press. The upper die holder 2 and the lower die holder 13 are vertically aligned, and multiple guide posts 28 are provided between them. When the press is working, it drives the upper die holder 2 to reciprocate up and down. The guide posts 28 are used to ensure that the upper die holder 2 and the lower die holder 13 are aligned when the press is working.
[0022] Along the feeding direction of the product strip 8, between the upper die holder 2 and the lower die holder 13, a feeding unit, a stamping unit, a feeding line, and a cutting unit are installed sequentially to complete the work of product feeding, stamping, automatic feeding, and waste removal, respectively. The receiving unit is installed on one side of the stamping machine. It is connected to the upper die holder 2 and the lower die holder 13 and moves with the relative movement of the upper die holder 2 and the lower die holder 13 to complete automatic receiving.
[0023] The feeding unit is used to position the product strip 8, ensuring it enters the stamping equipment flat. It includes a guide block 7, a float block 8, and a first spring. A through hole is provided on the lower die holder 13. The first spring is installed in this through hole, passing through the lower die holder 13, with its lower end abutting against the die foot 14. A float block 9 is installed at the top of the first spring. The guide blocks 7 are installed on both sides of the float blocks 9, positioned along the forward direction of the product strip 8. When the product strip 8 enters the feeding unit, the middle of the product strip 8 is lifted upward by the float block 9, while the guide blocks 7 on both sides of the product strip 8 press down from both sides and guide the product strip 8 in the direction of movement.
[0024] The stamping unit includes an upper stamping die connected to the upper die holder 2 and a lower stamping die connected to the lower die holder 13. It is used to complete the stamping process of the product strip 8 to obtain the final product. The stamping unit completes the stamping of three products at a time.
[0025] The stamping die includes an upper movable plate 3, an upper backing plate 4, a punch fixing plate 5, a die cavity 6, and a punch 15. The upper movable plate 3 is fixed below the upper die holder 3, the upper backing plate 4 is fixed below the upper movable plate 3, the punch fixing plate 5 is fixed below the upper backing plate 4, and the die cavity 6 is fixed below the punch fixing plate 5. The punch 15 is mounted on the punch fixing plate 5. A through hole is provided on the die cavity 6 corresponding to the position of the punch 15, allowing the punch 15 to protrude from the through hole in the die cavity 6. A stripper core 16 is also mounted on the die cavity 6, and the stripper core 16 is further fitted onto the punch 15.
[0026] The stamping die includes a lower backing plate 12, a punch fixing plate 11, and a punch and die 26. The lower backing plate 12 is fixed above the lower die holder, and the punch fixing plate 11 is fixed above the lower backing plate 12. The punch and die 26 and the blanking die 30 are mounted on the punch fixing plate 11, corresponding to the position of the punch 15. The blanking die 30 is mounted on the punch and die 26. A stripper plate 10 is also provided on the punch fixing plate 11. The stripper plate 10 has a through hole, through which the punch and die 26 and the blanking die 30 pass.
[0027] The feeding unit includes a backstop module and a side push module. The backstop module is located at the front of the feeding module. When the press moves downward, the side push module pushes the product strip 8 forward, while when the press moves upward, the backstop module ensures that the product strip 8, which has already been fed forward, will not retract.
[0028] The anti-reverse module is fixed on the lower die holder 13 and includes an anti-reverse pin 25 and an anti-reverse spring 27. The anti-reverse pin 25 is fitted onto the anti-reverse spring 27. The anti-reverse spring 27 is vertically mounted on the lower die holder 13, pushing the anti-reverse pin 25 upward. The top surface of the anti-reverse pin 25 is an inclined plane. When the product strip 8 moves forward, the product strip 8 presses against the anti-reverse pin 25 along the inclined plane, thereby compressing the anti-reverse spring 27, so that it is lower than the product strip 8 and does not obstruct the forward movement of the product strip 8. After the product strip 8 has moved forward one station, the anti-reverse spring 27 rebounds, pushing the anti-reverse pin 25 out and into the hole on the product strip 8 (i.e., the hole left after the product is stamped). Because the product strip 8 moves in the opposite direction, the side of the anti-reverse pin 25 is the height of the inclined plane, thus perpendicular to the product strip 8 and preventing the product strip 8 from moving backward.
[0029] The side-push module consists of a side-push punch 17 that fits between the upper and lower parts, and a feeding sub-module. The side-push punch 17 is connected to the upper die holder 2. The feeding sub-module is connected to the lower die holder 13 and includes a side-push block 24, a feeding pin 19, a feeding push block 21, a feeding push block guide block 30, a feeding spring, and a return spring. The side-push block 24 is located in front of the side-push punch 17. It fits with the side-push punch 17. When the side-push punch 17 is pressed down, it abuts against the side-push punch 17 from the front, ensuring that the side-push punch 17 moves vertically and is not pushed back by the product strip 8. The feeding pin 19 is fitted onto the feeding spring and is installed vertically upward inside the feeding push block 21, and is pushed upward by the feeding spring. The return spring is installed horizontally and abuts against the rear of the feeding push block 21 from back to front, pushing the feeding push block 21 forward. The push block guide block 30 is installed on both sides of the feeding push block 21. When the feeding pusher 21 is pushed, it moves along the direction of the feeding pusher guide block 30. When the side pusher punch 17 presses down, it pushes the inclined surface at the top of the feeding pin 19, pushing the feeding pin 19 forward. The feeding pin 19 extends into the hole in the product strip 8, pushing the product strip 8 forward one station, at which time the return spring is compressed. When the side pusher punch 17 moves up, the return spring returns to its original position, pushing the feeding pin 19 forward. At this time, the inclined surface at the top of the feeding pin 19 is squeezed by the product strip 8, and the feeding pin 19 is lower than the product strip 8, moving forward below the product strip 8. The product strip 8 is then braked by the anti-reverse module. When the return spring is fully reset, the feeding pin 19 reaches the previous hole on the product strip 8, the feeding spring resets, and pushes the feeding pin 19 into the hole, preparing for the next ejection.
[0030] The cutting unit includes a cutting punch 18, a cutting die 29, a cutting die base 23, and a side cutting stop 22. The cutting punch 29 is connected to the upper die set 2 and is driven by the press to move up and down reciprocally.
[0031] The cutting die base 23 is mounted on the lower die holder 13 and remains stationary. The cutting die 29 is mounted on the cutting die base 23, located directly below the cutting punch 29, and cooperates with the cutting punch 29 to cut off the waste material. The side cutting stop 22 is located behind the cutting punch 29. When the cutting punch 29 is pressed down, it abuts against the cutting punch 29 from back to front to ensure that the cutting punch 29 moves vertically.
[0032] Rear guide blocks 20 are installed on the cutting die base 23. The rear guide blocks 20 are located on both sides in front of the cutting die 29, one on the left and one on the right, along the direction of the product strip 8's movement. The rear guide blocks 20 are used to position the product strip 8 in the forward direction.
[0033] The receiving unit includes a receiving fixing seat 32, a receiving frame 33, and a receiving hopper 34. Multiple receiving fixing seats 32 are fixed to the upper mold frame 2 and the lower mold frame 13, respectively. The receiving frame 33 has a parallelogram structure, with two protruding legs connected to the receiving fixing seat 32. The receiving hopper 34 is connected to the receiving frame 33. When the upper mold frame 2 and the lower mold frame 13 approach each other, the receiving frame 33 compresses, causing the receiving hopper 34 to move outward, moving the product located in the receiving hopper 34 into a turnover box. When the upper mold frame 2 and the lower mold frame 13 separate, the receiving frame 33 extends, causing the receiving hopper 34 to move inward, completing the receiving process.
[0034] Please see Figure 4 The present invention also discloses a method for using the above-mentioned modular automatic feeding and automatic receiving stamping die, a preferred embodiment of which includes the following steps: Step S1: Install the product conveyor belt onto the feeding unit.
[0035] In step S2, the stamping machine operates, the upper die frame moves downward and approaches the lower die frame. The receiving unit moves outward.
[0036] Step S3: The feeding unit moves forward one station by pushing the product conveyor belt forward.
[0037] The side-push punch presses down, pushing the feeding submodule to advance the product strip one station.
[0038] In step S4, the stamping unit operates to stamp the product into shape. The cutting unit operates to cut off the waste material.
[0039] In a single operation of the stamping unit, three products are formed. In step S5, the upper die holder moves upward, away from the lower die holder, and the receiving unit enters the space between the stamping units.
[0040] In step S6, the product stamping unit completes unloading, and the product is received by the receiving unit.
[0041] The receiving unit receives three products simultaneously and transfers them into the turnover box.
[0042] Step S7: The feeding unit is reset. If production continues, proceed to step S1; otherwise, proceed to step S8.
[0043] The side-pushing punch moves upward, the feeding submodule resets, and at this time the anti-reverse module blocks the product strip from retracting.
[0044] Step S8, production complete.
[0045] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
