Description

Technical Field

[0001] This utility model relates to the field of high-speed stamping, and specifically to an in-die feeding mechanism for high-speed stamping dies. Background Technology

[0002] Stamping dies are specialized equipment used in cold stamping processes to shape materials (metal or non-metal) into parts (or semi-finished products). Existing stamping dies can only feed material once per upward and downward cycle of the press, resulting in wasted press stroke. Furthermore, high-speed stamping dies typically reach speeds exceeding 600 strokes per minute, and existing feeding mechanisms suffer from poor stability, making it difficult to further increase stamping speeds. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-speed stamping die in-die feeding mechanism with the advantages of stable feeding, high speed and good stability.

[0004] The purpose of this utility model is achieved through the following technical solution: This high-speed stamping die in-die feeding mechanism is used to feed material into a high-speed stamping die. The high-speed stamping die includes an upper die base and a lower die base disposed below the upper die base. An upper pad, a fixing plate, a stripper plate pad, and a stripper plate are sequentially connected below the upper die base. A die core plate is disposed below the stripper plate and is mounted on the lower die base via a die core plate pad. When the upper and lower die bases are closed, a gap is left between the stripper plate and the die core plate for the material feeder to enter. Its characteristic is that it includes: Slider A, a stop block A is fixed on the lower mold base on one side of slider A, a slider spring A is installed between the stop block A and slider A, so that slider A has the tendency to move away from the stop block A, and a fixing rod A is installed on slider A; Slider B, a stop block B is fixed on the lower mold base on the side of slider B away from stop block A, a slider spring B is installed between stop block B and slider B, so that slider B has the tendency to move away from stop block B, and a fixing rod B is installed on slider B. Two double-sided wedges are symmetrically fixed on the upper mold base. One double-sided wedge is located outside the slider A and contacts the fixed rod A through the double-sided wedge, thereby pushing or blocking the slider A. At the same time, the other double-sided wedge is located outside the slider B and contacts the fixed rod B through the double-sided wedge, thereby pushing or blocking the slider B. The sliding directions of slider A and slider B are opposite. A feeding plate is installed between slider A and slider B, and the material strip is placed on the feeding plate; A pusher component A is mounted on a slider A, floating up and down. When the slider A slides in the same direction as the feeding direction, the pusher component A slides along the feeding plate, thus feeding the material. When the slider A slides in the opposite direction to the feeding direction, the pusher component A is pressed into the feeding plate by the material belt. The pusher component B is mounted on the slider B in a floating manner. When the slider B slides in the same direction as the feeding direction, the pusher component B slides along the feeding plate through the slider B to achieve feeding. When the slider B slides in the opposite direction to the feeding direction, the pusher component B is pressed into the feeding plate by the material belt.

[0005] As a further technical solution, a groove A is opened on slider A, a groove B is opened on slider B, the other end of the fixing rod A extends into the groove B and passes through slider B, and the other end of the fixing rod B extends into the groove A and passes through slider A.

[0006] As a further technical solution, a through hole is opened on both slider A and slider B. Fixing rod A passes through the through hole on slider A and is fixed relative to slider A, and fixing rod B passes through the through hole on slider B and is fixed relative to slider B.

[0007] As a further technical solution, a blind hole is opened on both slider A and slider B. One end of slider spring A is fixed by stop block A, and the other end is installed in the blind hole of slider A; one end of slider spring B is fixed by stop block B, and the other end is installed in the blind hole of slider B.

[0008] As a further technical solution, bushings A are installed at both ends of the fixing rod A, and the bushings A contact the double-sided wedges. Bushings B are installed at both ends of the fixing rod B, and the bushings B contact the double-sided wedges.

[0009] As a further technical solution, the pusher part A is floatingly mounted on the slider A via the pusher part reset spring A, and the pusher part B is floatingly mounted on the slider B via the pusher part reset spring B.

[0010] As a further technical solution, both pusher parts A and B are provided with positioning protrusions on their tops, which are used to cooperate with the positioning holes on the material strip to achieve positioning, and the positioning protrusions adopt a beveled structure.

[0011] As a further technical solution, a track is opened on the feeding plate. In its natural state, the positioning protrusion protrudes from the track. When the pushing part A or the pushing part B is subjected to the pressure of the material belt, the positioning protrusion retracts into the track and disengages from the positioning hole, causing the material belt to move relative to the pushing part A or the pushing part B.

[0012] As a further technical solution, each double-sided wedge has a symmetrically arranged inclined surface at its lower part, and the spacing at the upper end of the inclined surface is greater than the spacing at the lower end of the inclined surface.

[0013] As a further technical solution, a clearance groove is provided on the lower mold base at the position corresponding to the double-sided wedge to avoid the inclined surface.

[0014] The beneficial effects of this utility model are as follows: 1. The double-sided wedge design transforms the opening and closing motion of the machine into the horizontal motion of the feeding mechanism, making full use of the opening and closing process to achieve double the feeding range. 2. The feeding distance is doubled by using the pusher parts and the return spring. When the mold opens, slider A feeds material while slider B does not feed material. The pusher part B on slider B is pressed into the track of the feeding plate and does not contact the material strip. When the mold closes, slider A does not feed material while slider B feeds material. The pusher part A on slider A is pressed into the track of the feeding plate and does not contact the material strip, thus achieving double the feeding distance. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings: Example: As attached Figures 1-9 As shown, this high-speed stamping die in-die feeding mechanism includes an upper die base 1, an upper pad 2, a fixed plate 3, a stripper plate pad 4, a stripper plate 5, a die core plate 6, a die core plate pad 7, a lower die base 8, a double-sided wedge 9, an inclined surface 9-1, an upper end of the inclined surface 9-2, a lower end of the inclined surface 9-3, a pusher part A10, a pusher part B11, a strip 12, a positioning hole 12-1, a pusher part return spring A13, a slider A14, a slider spring A15, a stop block A16, a fixing rod A17, a fixing rod B18, a stop block B19, a slider spring B20, a slider B21, a pusher part return spring B22, a bushing A23, a bushing B24, a slide groove A25, a slide groove B26, a through hole 27, a blind hole 28, a feeding plate 29, a track 30, a positioning protrusion 31, and a clearance groove 32.

[0026] Reference Appendix Figure 1 The high-speed stamping die includes an upper die base 1 and a lower die base 8 located below the upper die base 1. The upper die base 1 is connected in sequence to an upper pad 2, a fixing plate 3, a stripper plate pad 4, and a stripper plate 5. A die core plate 6 is located below the stripper plate 5. The die core plate 6 is mounted on the lower die base 8 through a die core plate pad 7. When the upper die base 1 and the lower die base 8 are closed, a gap is left between the stripper plate 5 and the die core plate 6 for the material feed belt 12 to enter.

[0027] like Figure 2 , 3As shown in Figures 4 and 6, a stop block A16 is fixed on the lower die base 8 on one side of slider A14. A slider spring A15 is installed between the stop block A16 and slider A14, giving slider A14 a tendency to move away from the stop block A16. In addition, a fixing rod A17 is also installed on slider A14. A stop block B19 is fixed on the lower die base 8 on the side of slider B21 (away from the stop block A16). A slider spring B20 is installed between the stop block B19 and slider B21, giving slider B21 a tendency to move away from the stop block B19. In addition, a fixing rod B18 is also installed on slider B21.

[0028] Further, see attached document. Figure 1 , 8 Slider A14 and slider B21 have the same structure. Slider A14 has a waist-shaped groove A25, and slider B21 has a waist-shaped groove B26. The other end of fixing rod A17 extends into groove B26 and passes through slider B21, while the other end of fixing rod B18 extends into groove A25 and passes through slider A14. Both slider A14 and slider B21 have a through hole 27. Fixing rod A17 passes through the through hole 27 in slider A14 and is fixed relative to slider A14. Fixing rod B18 passes through the through hole 27 in slider B21 and is fixed relative to slider B21. Preferably, both slider A14 and slider B21 have a blind hole 28. One end of slider spring A15 is fixed by stop block A16, and the other end is inserted into the blind hole 28 of slider A14; one end of slider spring B20 is fixed by stop block B19, and the other end is inserted into the blind hole 28 of slider B21.

[0029] Preferably, bushings A23 are installed at both ends of the fixing rod A17, and the bushings A23 contact the double-sided wedge 9. Bushings B24 are installed at both ends of the fixing rod B18, and the bushings B24 contact the double-sided wedge 9.

[0030] Furthermore, such as Figure 2 , 3 As shown in Figure 7, two double-sided wedges 9 (upper ends) are symmetrically fixed on the upper mold base 1. One double-sided wedge 9 is located outside the slider A14, and contacts the fixing rod A17 through this double-sided wedge 9, thereby pushing or blocking the slider A14. At the same time, the other double-sided wedge 9 is located outside the slider B21, and contacts the fixing rod B18 through this double-sided wedge 9, thereby pushing or blocking the slider B21. The sliding directions of slider A14 and slider B21 are opposite. Preferably, each double-sided wedge 9 has a symmetrical inclined surface 9-1 at its lower part, and the spacing of the upper ends 9-2 of the inclined surfaces is greater than the spacing of the lower ends 9-3 of the inclined surfaces. A clearance groove 32 is provided on the lower mold base 8 at the corresponding position of the double-sided wedge 9 to avoid the inclined surface 9-1 during mold closing.

[0031] like Figure 4 , 5As shown in Figure 6, the feeding plate 29 is installed between slider A14 and slider B21, and the material strip 12 is placed on the feeding plate 29. During the feeding process, the material strip 12 is pressed downward on the feeding plate 29. The pushing part A10 is mounted on slider A14 by the pushing part return spring A13. When the sliding direction of slider A14 is consistent with the feeding direction, the pushing part A10 is driven by slider A14 to slide along the feeding plate 29 to realize feeding; when the sliding direction of slider A14 is opposite to the feeding direction, the pushing part A10 is pressed into the feeding plate 29 by the material strip 12. The pusher component B11 is mounted on the slider B21 by a pusher component return spring B22. When the sliding direction of the slider B21 is consistent with the feeding direction, the pusher component B11 is driven to slide along the feeding plate 29 to achieve feeding. When the sliding direction of the slider B21 is opposite to the feeding direction, the pusher component B11 is pressed into the feeding plate 29 by the material belt 12.

[0032] Furthermore, both the pusher part A10 and the pusher part B11 are provided with positioning protrusions 31 on their tops, which can cooperate with the positioning holes 12-1 on the material strip 12 to achieve positioning (e.g., Figure 6 , 9 As shown in the figure, the positioning protrusion 31 adopts a beveled structure, which facilitates being pressed into the feeding plate 29 (track 30) when the sliding direction is opposite to the feeding direction. Preferably, a track 30 is provided on the feeding plate 29. In the natural state (with the return spring extended), the positioning protrusion 31 protrudes from the track 30. When the pushing part A10 or the pushing part B11 is subjected to the pressure of the material belt 12 (the return spring is compressed), the positioning protrusion 31 retracts into the track 30 and disengages from the positioning hole 12-1, so that the material belt 12 can move relative to the pushing part A10 or the pushing part B11.

[0033] The working process of this utility model: When the mold is opened, after the double-sided wedge 9 moves upward a certain distance, the upper end 9-2 of the inclined surface of the double-sided wedge 9 begins to contact the fixed rod A17 (sleeve A23) and the fixed rod B18 (sleeve B24). Since the fixed rod A17 and the pusher part A10 are connected to the slider A14, they move to the right as a whole under the action of the slider spring A15 and the stop block A16, which plays the role of feeding (half a step distance). Meanwhile, the fixed rod B18 and the pusher part B11, being fixed on the slider B21, move to the left under the action of the slider spring B20 and the stop block B19. Under the downward pressure of the inclined surface of the positioning protrusion 31 and the material strip 12, the pusher part B11 compresses the pusher part reset spring B22, and the positioning protrusion 31 on the pusher part B11 retracts into the track 30 and disengages from the positioning hole 12-1, allowing the material strip 12 to move relative to the pusher part B11. After the mold opening and feeding are completed, the pusher part B11 resets under the action of the pusher part reset spring B22, causing the positioning protrusion 31 to protrude from the track 30 and be positioned with the positioning hole 12-1 again.

[0034] During mold closing, the double-sided wedge 9 moves downwards, and the lower end 9-2 of the inclined surface of the double-sided wedge 9 begins to contact the fixed rod A17 and the fixed rod B18. The fixed rod B18, the pusher part B11, and the slider B21 move to the right under the action of the double-sided wedge 9, which serves as the feeding function (the other half of the step distance). At the same time, the fixed rod A17, the pusher part A10, and the slider A14 move to the left under the action of the double-sided wedge 9. Under the downward pressure of the inclined surface of the positioning protrusion 31 and the material strip 12, the pusher part A10 compresses the pusher part return spring A13. The positioning protrusion 31 on the pusher part A10 retracts into the track 30 and disengages from the positioning hole 12-1, allowing the material strip 12 to move relative to the pusher part A10. After the mold closing and feeding are completed, the pusher part A10 returns to its original position under the action of the pusher part return spring A13, causing the positioning protrusion 31 to protrude from the track 30 and be positioned with the positioning hole 12-1 again.
