[0039] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. According to one embodiment of the present invention, a mechanical brake card stamping die is provided. The overall structural diagram of the stamping die is shown in FIG. Figure 1 As shown, the stamping die includes a press head 1, an action component 2, a die base component 3, a limit component 4 and a frame 5. The press head 1 is connected to the action component 2, the action component 2 is connected to the die base component 3, the limit component 4 fixes the action component 2 on the frame 5, the die base component 3 includes a lower die base 31, a first upper die base 32, a second upper die base 33 and a side die base 34, the lower die base 31 is fixed on the frame 5, and is used to place the workpiece to be stamped. The first upper die base 32, the second upper die base 33 and the side die base 34 move to the lower die base 31 to complete the workpiece stamping; the action component 2 includes The first action component, the second action component and the third action component, the first action component is connected to the first upper die base 32, driving the movement of the first upper die base 32, the second action component is connected to the second upper die base 33, driving the movement of the second upper die base 33, the third action component is connected to the side die base 34, driving the movement of the side die base 34; the press head 1 is respectively connected to the first action component, the second action component and the third action component, used to drive the first action component, the second action component and the third action component to drive the first upper die base 32, the second upper die base 33 and the side die base 34 to stamp the workpiece.

[0040] In a preferred case, the press head 1 drives the first action component, the second action component and the third action component at the same time. The three action components are respectively connected to the first upper die base 32, the second upper die base 33 and the side die base 34. By designing the action strokes of the three action components, the first upper die base 32, the second upper die base 33 and the side die base 34 complete the stamping work of the workpiece with the lower die base 31 in turn. The driving mode of the press head 1 is not limited here, and it can be an electric, pneumatic or hydraulic driving mode. The connection mode between the press head 1 and the action component 2 is also not limited. It only needs to be able to complete the action by driving the action component through the press head 1. It should be noted that the first action component, the second action component and the third action component are respectively fixedly connected to the first upper die base 32, the second upper die base 33 and the side die base 34. Preferably, a detachable connection is adopted to facilitate the inspection and maintenance of the stamping die and the replacement of the die base assembly 3.

[0041] Combine Figure 3The first and second motion components include a punch 21, a push rod 22, and a pressure rod 23. The punch 21 is connected to the push rod 22, and the pressure rod 23 is connected to the die base assembly 3. The press head 1 drives the punch 21 to move, and the punch 21 drives the push rod 22 to move toward the pressure rod 23 to push the die base assembly 3 connected to the pressure rod 23 to move. The connection method between the punch 21 and the push rod 22 is not limited here. Optionally, screw connection, clamping connection or welding are adopted. Preferably, the first and second motion components are provided with universal joints at both ends of the push rod 22 to ensure the force transmission effect of the motion component 2 during the movement process. Furthermore, the limit assembly 4 includes a first limit block 41 and a second limit block 42, which are used to limit the position and movement direction of the action assembly 2 on the frame 5; the first limit block 41 and the second limit block 42 are provided with through holes in the movement direction of the action assembly 2, which are used for the action assembly 2 to move in this direction. Preferably, the first limit block 41 is fixed to the side of the frame 5 close to the press head 1, and the punch rod 21 passes through the through hole of the first limit block 41 to limit the punch rod 21, so that the punch rod 21 moves along the through hole direction of the first limit block 41 under the drive of the press head 1; the second limit block 42 is fixed to the side of the frame 5 close to the die base assembly 3, and the pressure rod 23 passes through the through hole of the second limit block 42 to limit the pressure rod 23, so that the pressure rod 23 moves along the through hole direction of the second limit block 42 under the push of the push rod 22, thereby making the first upper die base 32, the second upper die base 33 and the side die base 34 move in the specified direction, thereby completing the stamping of the workpiece. It should be noted that the limit assembly 4 and the frame 5 are fixedly connected and their positions are fixed during the stamping process. Preferably, the through holes of the first limit block 41 and the second limit block 42 are slidably connected to the punch rod 21 and the pressure rod 23, so that the punch rod 21 and the pressure rod 23 can move relative to the first limit block 41 and the second limit block 42, and the movement direction is limited to the intended movement direction of the first upper mold base 32, the second upper mold base 33 and the side mold base 34 connected to the pressure rod 23. Furthermore, each action component 2 also includes a first spring 24 and a second spring 25. The first spring 24 is sleeved on the outside of the push rod 22 and abuts against the punch rod 21. Preferably, the punch rod 21 and the push rod 22 can slide with each other. There is a sliding space for the push rod 22 inside the punch rod 21. During the stamping process, the sliding space is reduced and the first spring 24 is compressed. After the stamping is completed, the first spring 24 resets the relative position of the punch rod 21 and the push rod 22; the second spring 25 is sleeved on the outside of the pressure rod 23 and abuts against the second limit block 42. During the stamping process, the pressure rod 23 passes through the through hole of the second limit block 42. At this time, the second spring 25 is in a compressed state. After the stamping is completed, the second spring 25 resets the pressure rod 23.In a preferred case, the push rod 22 and the pressure rod 23 in the first action component are separated by a first distance, and the push rod 22 and the pressure rod 23 in the second action component are separated by a second distance, and the first distance is smaller than the second distance. Through such an arrangement, the press head 1 starts to move at the same time when driving the first action component and the second action component. The second distance between the push rod 22 and the pressure rod 23 in the second action component is relatively large, so that the stroke of the second action component driving the second upper die base 33 to complete the stamping is also relatively large, thereby realizing that the first upper die base 32 completes the stamping action in advance. Before the second upper die base 33 stamps, the first upper die base 32 is always in an extrusion state with the lower die base 31, thereby fixing the workpiece to be stamped so that the second upper die base 33 can complete the stamping ; Preferably, the first action component and the second action component also include a first connecting rod 26, the first connecting rod 26 is a tubular structure, the first connecting rod 26 is fixed to one end of the punch rod 21 close to the push rod 22, and the push rod 22 and the first connecting rod 26 are slidably connected. Through such an arrangement, the first connecting rod 26 enables the punch rod 21 and the push rod 22 to have a distance of relative movement during the stamping process. After the stamping is completed, the first spring 24 resets the relative position of the punch rod 21 and the push rod 22. Furthermore, by setting the length of the two first connecting rods 26 in the first action component and the second action component, the stroke of the first action component and the second action component can be adjusted to further ensure that the first upper die base 32 and the second upper die base 33 driven by it complete the stamping action in succession.

[0042] Combine Figure 4 , Figure 4It is a schematic structural diagram of the third action component of the stamping die of an embodiment, wherein the second limit block 42 fixes the pressure rod 23 of the third action component horizontally on the frame 5, so that the pressure rod 23 drives the side die base 34 to move horizontally toward the lower die base 31, thereby completing the lateral stamping of the workpiece; preferably, the limit assembly 4 also includes a guide rail 43, the guide rail 43 is horizontally fixed on the frame 5, and the push rod 22 of the third action component is slidably connected to the guide rail 43. Through such an arrangement, the push rod 22 slides on the horizontally arranged guide rail 43, thereby pushing the pressure rod 23, which is convenient for controlling the stroke direction of the third action assembly, so that the push rod 22 is more accurate in understanding the direction of the pressure rod 23, and the pushing effect is more stable. In a preferred case, the first limit block 41 vertically fixes the punch rod 21 of the third action component on the frame 5, and the third action component also includes a second connecting rod 27, and the punch rod 21 is connected to the push rod 22 through the second connecting rod 27. Through such an arrangement, the vertically arranged punch rod 21 makes the press head 1 have a better driving effect on the punch rod 21, and the second connecting rod 27 is connected to the push rod 22 to drive the push rod 22 to move; further, one end of the second connecting rod 27 is connected to the punch rod 21 and can move in the vertical direction, and the other end of the second connecting rod 27 is connected to the push rod 22 and can move in the horizontal direction. Through such an arrangement, the movement amplitude of the second connecting rod 27 during the stamping process can be reduced, and at the same time, the vertically arranged punch rod 21 pushes the push rod 22 to move in the horizontal direction. In a preferred case, before the stamping action starts, that is, when the press head 1 moves, the push rod 22 contacts the pressure rod 23 Before, the angle between the second connecting rod 27 and the horizontal is greater than 45 degrees. Through such an arrangement, the angle between the second connecting rod 27 and the horizontal gradually becomes smaller during the stamping process. Before the angle between the second connecting rod 27 and the horizontal is reduced to 45 degrees, the stroke change frequency of the punch rod 21 is less than the stroke change frequency of the push rod 22, that is, when the punch rod 21 moves downward by a certain stroke, the stroke is less than the stroke of the horizontal movement of the push rod 22, which is conducive to the relatively rapid movement of the push rod 22 toward the pressure rod 23; preferably, after the push rod 22 and the pressure rod 23 contact, the pressure rod 23 and the side mold base 34 are pushed to move, and the angle between the second connecting rod 27 and the horizontal is less than or equal to 45 degrees. Through such an arrangement, the stroke change frequency of the punch rod 21 is greater than the stroke change frequency of the push rod 22 and the pressure rod 21, so that the side mold base 34 moves slowly toward the lower mold base 31, ensuring the stamping effect while protecting the mold base assembly 3. It should be noted that when the stroke requirements of step-by-step stamping are met, the angle range between the second connecting rod 27 and the horizontal is not limited. The main purpose of setting the second connecting rod 27 is to increase the stroke of the third action component and make the overall structure more compact and save space.

[0043] Furthermore, after the die base assembly 3 completes the stamping, the press head 1 drives the action assembly 2 to drive the first upper die base 32, the second upper die base 33 and the side die base 34 to separate and reset from the lower die base 31 at the same time. Through such a setting, it is possible to realize that one press head 1 controls three action assemblies 2 to complete the action at the same time, and different structural arrangements of the three action assemblies 2 are set so that the stroke of each action assembly 2 is different, thereby realizing the simultaneous control of each action assembly 2 to complete the step-by-step stamping. During the step-by-step stamping process, the die base that completes the stamping with the lower die base 31 is fixed, and after all the die bases complete the stamping, the first upper die base 32, the second upper die base 33 and the side die base 34 are separated and reset from the lower die base 31 at the same time, so that the position of the workpiece to be stamped is fixed during the stamping process, and the stamping effect is better. At the same time, the three action assemblies are controlled simultaneously by one press head, which saves the overall space and makes the operation simpler and more convenient.

[0044] In summary, the utility model provides a mechanical brake card stamping die, in which the press head controls the simultaneous movement of three action components, and designs the stroke difference of the three action components, thereby realizing step-by-step stamping of the workpiece, which is suitable for the processing of multiple varieties of fixed plates to the greatest extent, and adapts to the production mode of multiple varieties and small batches, while solving the tedious process of step-by-step processing and improving the processing efficiency and quality of the workpiece.

[0045] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
