Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of multi-station stamping dies, and particularly relates to a multi-station stamping die with a self-resetting function. Background Art
[0002] Cold stamping is a pressure processing method that applies pressure to materials using a die installed on a press at room temperature to cause separation or plastic deformation, thereby obtaining the required parts. A stamping die is a special process equipment that processes materials (metal or non-metal) into parts or semi-finished products in cold stamping processing, also known as a cold stamping die or a cold punching die.
[0003] With the continuous increase in market demand and productivity, in order to achieve high-efficiency and high-precision batch production of products, multi-station stamping dies are now often used to achieve batch processing. Such dies can continuously complete complex processes such as stamping, bending, shearing, and forming of materials through multiple stations (or stations) in one working cycle, significantly improving production efficiency and product consistency.
[0004] However, in order to meet technical and safety requirements, the design of multi-station stamping dies, whether it is a grading die or a progressive die, requires space and time for switching. In this process, the most crucial is the adjustment of the relative position between the upper and lower dies. Usually, the lower die is moved to adapt to the upper die of different stations to ensure the precise alignment of the die during each stamping.
[0005] As the number of stations in a multi-station die increases, the overall size of the die also increases. This not only requires more physical space to install and operate the die, but also increases the complexity and time consumption of mechanical movement during die switching. Especially when using a small stamping machine or equipment with a small pressure, the physical size limitations and power performance of these devices often cannot meet the high requirements of multi-station dies for space and time switching. Small devices may not be able to provide enough stroke to move the lower die, or their working cycle is too short to complete all necessary die switching and stamping actions within the given time, thus restricting the application of multi-station dies on these devices.
[0006] Therefore, in order to solve the problems that existing multi-station dies cannot meet the production use of small or low-pressure devices, resulting in easy errors during stamping, etc., there is a need to provide a multi-station stamping die with a self-resetting function. Summary of the Utility Model

[0026] The embodiment is basically as shown in the appendix Figure 1 as follows: A multi-station stamping die with a self-resetting function includes a die base 1 and an upper die 2 correspondingly installed thereon. A T-shaped groove 3 is formed in the die base 1, and the die end of the upper die 2 is movably arranged in the T-shaped groove 3 and can move up and down in the T-shaped groove 3 for stamping.
[0027] A gear position groove 4 is formed in the die base 1, Figure 1 As shown in the perspective view, a limiting block 5 is slidably arranged at the left end of the gear position groove 4, enabling the limiting block 5 to move left and right in the gear position groove 4. A plurality of gear position components 6 are arranged at the right end of the gear position groove 4. In this embodiment, there are a plurality of gear position grooves 4, and the gear position components 6 are respectively arranged in the corresponding gear position grooves 4. As shown in the appendix Figure 2 as shown, a total of 4 gear position grooves 4 are arranged side by side. Taking the appendix Figure 2 perspective view as an example, for the convenience of description and operation, the one located at the upper end of the view is set as the zero position 7, and the ones below it are the first position 8, the second position 9, and the third position 10 in sequence. Among them, the gear position component 6 located at the zero position 7 is a reset component for resetting the gear position component 6, and the other positions are die gear position components for stamping the corresponding gear position component 6 with the corresponding upper die 2 to achieve multi-station stamping. In this embodiment, the die gear position components are respectively the first die gear position component, the second die gear position component, and the third die gear position component. The upper die 2 is correspondingly arranged above the gear position component 6 and contacts and stamps with a single die gear position component respectively.
[0028] As shown in the appendix Figure 2 as follows, taking the reset component as an example for illustration, the gear position component 6 includes a slider 11 slidably arranged in the gear position groove 4. A guide rod 12 is arranged at the left end of the slider 11 along the X-axis direction. A hook head 13 is fixedly installed at the left end of the guide rod 12 through a bolt. An elastic member 14 is arranged between the slider 11 and the hook head 13, and the elastic member 14 is sleeved on the guide rod 12. In this embodiment, the elastic member 14 can adopt a spring. At the same time, for the convenience of operation and use, the gear position component 6 further includes a handle 15. In this embodiment, the handle 15 is integrally formed with the guide rod 12, and a handle is formed by passing the guide rod 12 through the slider 11, which is arranged at the right end of the slider 11 and extends to the outside of the die base 1 for easy operation. In this embodiment, the structures of the reset component, the first die gear position component, the second die gear position component, and the third die gear position component are the same and will not be elaborated here. Correspondingly, the upper die 2 includes a plurality of dies, and each die is correspondingly arranged above each slider 11, and contacts the die of the upper die 2 at the corresponding position by sliding the slider 11, so as to ensure accurate stamping.
[0029] A stopper 16 is further arranged in the gear position groove 4 along the Y-axis direction. The stopper 16 penetrates through the gear position groove 4 and elastically contacts the left ends of the elastic members 14 of each gear position component 6 respectively.
[0030] On one side of the limit block 5, there are multiple card slots. One side of the card slots faces the slider hook head and is installed in the gear slot 4 of the die base 1. Among them, the card slot corresponding to the zero position is the reset card slot 17, and the card slots at the remaining positions are the die gear card slots 18. The front hook head 13 of the reset component is in sliding contact with the reset card slot 17, and the front hook heads of the die gear components are respectively in sliding contact with the corresponding die gear card slots 18, so that only one gear of the gear component 6 is in contact with the corresponding card slot.
[0031] As shown in the attached Figure 3 figure, the limit block 5 includes the reset card slot 17 located above, and the die gear card slots at the first position, the second position, and the third position located below in sequence. In this embodiment, the reset card slot 17 includes a receiving cavity 19 with an overall rectangular structure. The lower side surface of the receiving cavity 19 is a slope surface 20 with a certain slope. In this embodiment, the inclination angle of the slope surface 20 is 30°, so as to facilitate the movement of the hook head 13 in the card slot without being blocked. The die gear card slot 18 includes an irregular receiving cavity 21. Among them, the irregular receiving cavity 21 includes a rectangular groove with an overall square shape. A positioning platform 22 protruding in the Y-axis direction is provided on the lower side surface of the rectangular groove. The hook head 13 at the corresponding gear is fixed in the card slot through the clamping cooperation between the positioning platform 22 and the hook head 13, so as to realize gear switching and adjustment. In this embodiment, the height of the positioning platform 22 is set to 10 - 15 mm, and its inclination angle is set to 15 - 25°, so as to ensure the stability of the clamping of the hook head 13. At the same time, when switching gears, it is also easy to fall off, ensuring smooth gear switching. In this embodiment, the die gear card slots at the first position, the second position, and the third position have the same structure and will not be elaborated here.
[0032] A gear shifter 23 is also installed below the limit block 5. In this embodiment, the gear shifter 23 includes a compression spring 24 elastically connected to the limit block 5. A spring pressing block 25 is installed outside the compression spring 24. The compression spring 24 is fixed on the die base 1 through the spring pressing block 25. At the same time, the spring pressing block 25 is installed and fixed on the die base 1 through two left and right compression bolts.
[0033] The specific implementation process is as follows:
[0034] As shown in the attached Figure 1 to the attached Figure 3As shown in the figure, after the corresponding hook head 13, elastic member 14, guide rod 12, slider 11 and handle 15 are assembled in sequence, they are correspondingly installed in the gear slot 4. Among them, the gear slot 4 includes four chutes. After assembly, the reset assembly is restricted in the zero - number chute by the stopper 16, the first - mold gear assembly is restricted in the first chute by the stopper 16, the second - mold gear assembly is restricted in the second chute by the stopper 16, and the third - mold gear assembly is restricted in the third chute by the stopper 16. Four molds of the upper die 2 are installed in the T - shaped slot of the die base 1. The side of the card slot of the limit block 5 faces the hook head of the slider and is installed in the gear slot 4 of the die base 1.
[0035] When in a static state, the limit block 5 is pressed against the forward position by the thrust of the compression spring 24 of the shifting device 23. The zero - position slider, first - position slider, second - position slider and third - position slider are all pressed by the corresponding elastic member 14 against the right - hand end of the gear slot 4 of the die base 1. At this time, the upper die 2 is correspondingly in the zero position.
[0036] During operation, when the handle 15 at the first position is pushed, the slider 11 at the first position drives the hook head 13 at the first position to slide in the gear slot 4 towards the card slot of the limit block 5. When it contacts the limit block 5, it will first push the limit block 5 to move backward. When the hook head 13 at the first position moves to the leftmost end, the limit block 5 moves forward due to the thrust of the compression spring 24 of the shifting device 23. At this time, the hook head 13 at the first position is stuck on the positioning table 22 of the corresponding first - position special - shaped accommodating cavity 21, so that the slider 11 at the first position is just in the position below the T - shaped slot 3. When the press is pressed down, the slider 11 at the first position contacts the mold at the corresponding position of the upper die 2, while the sliders at other positions do not contact the mold, thus realizing a working process.
[0037] When the handle 15 at the second position is pushed, the slider 11 at the second position drives the hook head 13 at the second position to slide in the gear slot 4 towards the card slot of the limit block 5. When it contacts the limit block 5, it will first push the limit block 5 to move backward. At this time, the hook head 13 at the first position comes off the positioning table 22, and the slider 11 at the first position slides to the right - hand end of the gear slot 4 of the die base 1 under the pulling force of the elastic member 14, realizing the reset of the first position.
[0038] At the same time, when the hook head 13 at the second position moves to the leftmost end, the limit block 5 moves forward due to the thrust of the compression spring 24 of the shifting device 23. At this time, the hook head 13 at the second position is stuck on the positioning table 22 of the corresponding second - position special - shaped accommodating cavity 21, so that the slider 11 at the second position is just in the position below the T - shaped slot 3. When the press is pressed down, the slider 11 at the second position contacts the mold at the corresponding position of the upper die 2, while the sliders at other positions do not contact the mold, thus realizing a working process.
[0039] When the handle 15 at the third position is pushed, the slider 11 at the third position drives the hook head 13 at the third position to slide in the gear slot 4 towards the card slot of the limit block 5. When it contacts the limit block 5, it will first push the limit block 5 to move backward. At this time, the hook head 13 at the second position is disengaged from the positioning table 22, and the slider 11 at the second position slides to the rightmost end of the gear slot 4 of the die holder 1 under the pulling force of the elastic member 14 at the second position, realizing the reset of the second position.
[0040] At the same time, when the hook head 13 at the third position moves to the leftmost end, the limit block 5 moves forward due to the thrust of the compression spring 24 of the shift lever 23. At this time, the hook head 13 at the third position is stuck on the positioning table 22 of the special-shaped accommodation cavity 21 corresponding to the third position, making the slider 11 at the third position just located below the T-shaped slot 3. When the press is pressed down, the slider 11 at the third position contacts the die at the corresponding position of the upper die 2, while the sliders at other positions do not contact the die, thus realizing a working process.
[0041] When the handle 15 at the zero position is pushed, the slider 11 at the zero position drives the hook head 13 at the zero position to slide in the gear slot 4 towards the card slot of the limit block 5. When it contacts the limit block 5, it will first push the limit block 5 to move backward. At this time, the hook head 13 at the third position is disengaged from the positioning table 22, and the slider 11 at the third position slides to the rightmost end of the gear slot 4 of the die holder 1 under the pulling force of the elastic member 14 at the third position, realizing the reset of the third position.
[0042] And at the same time, because the ramp surface 20 structure in the reset card slot 17 cannot be connected to the hook head 13 at the zero position, at this time, the slider 11 at the zero position will be pulled by the elastic member 14 and move to the rightmost end of the gear slot 4, realizing the reset of the zero position. Of course, in this embodiment, the examples are executed in sequence according to the position numbers. In the actual operation process, the production sequence process and the reset state can be flexibly adjusted according to the situation requirements, which are not limited here.
[0043] In this embodiment, the T-shaped slot is arranged in the die holder, enabling the upper die to directly move up and down in the T-shaped slot to realize stamping. And by designing the clearance between the T-shaped slot and the slider, it is ensured that the rest of the die holder does not contact the lower die or the workpiece during work, avoiding the large space and complex structure required to avoid the interference of the rest of the upper and lower dies when the ordinary upper and lower dies are placed side by side. Furthermore, the structure of the upper die can be made more compact, and multi-station dies can be used in a small space, thus meeting the use requirements of small or small-pressure equipment. At the same time, the self-resetting upper die switching structure has only one gear that can work during the actual operation process, ensuring the correct use of the die corresponding to the upper die, avoiding the situation of misusing and mixing, guaranteeing the production efficiency and effectiveness, and improving the production efficiency.
[0044] The above are only the embodiments of the present utility model, and common general technical solutions and / or characteristics in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solutions of the present utility model, several deformations and improvements can be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
