Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: Refer to Figure 1 - Figure 6 As shown: In this embodiment, a stamping device for a new energy seat frame is included, comprising a template body 1, a positioning component 2 disposed on the template body 1, a pressing component 3 mounted above the template body 1, and an adaptive pressure equalizing component 4 disposed between the pressing component 3 and the template body 1. The positioning component 2 includes a motor 201, a connecting rod 202 connected to the output end of the motor 201, a movable rod 203 linked to the connecting rod 202, a first positioning frame 204 driven by the movable rod 203, a second positioning frame 205 cooperating with the first positioning frame 204, a first spring 206 connecting the first positioning frame 204 and the second positioning frame 205, and a silicone pad 207 disposed inside the first positioning frame 204 and the second positioning frame 205. Component 3 includes a pressing device body 301, a fixing plate 302 connected to the pressing device body 301, a support frame 303 supporting the fixing plate 302, a fixing column 304 disposed below the fixing plate 302, and a pressure plate 305 connected to the telescopic end of the pressing device body 301. The adaptive pressure equalization component 4 includes a heat-conducting plate 401 connected to one end of the fixing column 304, a slide rail 402 and a fixing block 403 disposed on the heat-conducting plate 401, a slider 404 cooperating with the slide rail 402, a connecting rod frame 405 connecting the fixing block 403 and the slider 404, a guide rod 407 movably connected to the top of one of the sliders 404, and a connecting plate 406 connected to the other end of the guide rod 407, wherein the top of the connecting plate 406 is fixedly connected to the bottom of the pressure plate 305.

[0028] The effect achieved by the entire embodiment one is as follows: When the new energy seat frame is stamped, the positioning component 2 is first activated, the motor 201 outputs power to drive the connecting rod 202 to rotate, the connecting rod 202 drives the movable rods 203 connected on both sides, and the two movable rods 203 in turn drive the first positioning frame 204 and the second positioning frame 205 to move. At this time, the first spring 206 between the first positioning frame 204 and the second positioning frame 205 can use its elasticity to achieve adaptive buffering, so that the two can firmly clamp the new energy seat frame blank, and at the same time, the first positioning frame 204 and the second positioning frame 205 are within The silicone pads 207 on the sides not only prevent damage to the skeleton surface but also increase friction to ensure accurate positioning, thus stably confining the skeleton blank to the template body 1. Subsequently, the pressing assembly 3 begins to operate. The telescopic end of the pressing device body 301 (such as a hydraulic drive cylinder or servo electric cylinder) pushes the pressure plate 305 downward. The fixed plate 302 remains stable under the support of the support frame 303, while the fixed column 304 provides structural connection and stability for the movement of the pressure plate 305. At the same time, the adaptive pressure equalization assembly 4 plays a role: when the pressure plate 305 moves downward, the connecting plate fixed at its bottom... 406 then moves downwards, and the connecting plate 406 pulls the guide rod 407. The guide rod 407 drives the slider 404 to slide within the slide rail 402 on the heat-conducting plate 401. The linkage frame 405, composed of multiple hinged connecting rods, between the slider 404 and the fixed block 403 expands or contracts with the movement of the slider 404. Utilizing the polygonal telescopic characteristics of the linkage frame 405, it automatically pulls the pressure of the pressing assembly 3, achieving uniform pressing. Simultaneously, the heat-conducting plate 401 can quickly conduct away the heat generated during stamping, preventing the seat frame material from deforming due to overheating. The advantage of this linkage method is that the positioning assembly 2, through... Spring buffers and silicone pads 207 provide protection, improving positioning accuracy and preventing workpiece damage. The pressing assembly 3 provides sufficient and stable stamping power through a stable mechanical structure. The adaptive pressure equalization assembly 4 uses the adaptive adjustment of mechanical linkages to ensure uniform pressing force in different parts and adapt to the frame profile. It also has a thermal management function. The three components work together to ensure the surface accuracy and stress uniformity of the new energy seat frame after stamping, reducing the scrap rate. They also enhance the adaptability of the device to frames of different specifications, extend the service life of molds and equipment, and ultimately improve production efficiency and product quality.

[0029] Example 2: According to Figure 1 - Figure 6As shown: The adaptive pressure equalization component 4 also includes a second spring 408, a sliding sleeve 409 fitted inside the second spring 408, and a sliding rod 410 passing through the sliding sleeve 409. The second spring 408 is connected between the pressure plate 305 and the heat-conducting plate 401. The connecting rod 202 is fixedly connected to the output shaft of the motor 201 via a coupling. The movable rod 203 is movably connected to the connecting rod 202. The first positioning frame 204 and the second positioning frame 205 are arranged in a U-shaped structure opposite to each other. The number of first springs 206 is at least two, and they are symmetrically distributed between the first positioning frame 204 and the second positioning frame 205. The silicone pad 207 is fixed to the inner sidewall of the first positioning frame 204 and the second positioning frame 205 by adhesive bonding, and the inner surface of the silicone pad 207 is provided with It has an anti-slip texture. The fixing plate 302 is fixedly connected to the outer surface of the pressing device body 301 by bolts. The support frame 303 consists of two symmetrically arranged columns. The lower surface of the heat-conducting plate 401 is provided with stamped protrusions that are adapted to the shape of the new energy seat frame. The heat-conducting plate 401 is a copper heat-conducting plate 401, and the heat-conducting plate 401 has a cooling channel inside. The inlet and outlet of the cooling channel extend to the outside of the template body 1. The connecting rod frame 405 is composed of multiple hinged connecting rod units to form a telescopic rhomboid or polygonal connecting rod structure. The fixing block 403 and the slider 404 are respectively connected to the adjacent nodes of the connecting rod structure. The two ends of the second spring 408 abut against the connecting plate 406 and the sliding sleeve 409 respectively. The sliding sleeve 409 and the sliding rod 410 are in clearance fit.

[0030] The effect achieved by the entire embodiment two is as follows: the motor 201 drives the connecting rod 202 to rotate through the coupling. Since the movable rod 203 and the connecting rod 202 are movably connected, the connecting rod 202 can drive the movable rod 203, thereby driving the first positioning frame 204, which has a relatively U-shaped structure, to move. At this time, the two first springs 206, which are symmetrically distributed between the first positioning frame 204 and the second positioning frame 205, provide elastic buffering, so that the two can adaptively clamp the new energy seat frame blank. At the same time, the silicone pads 207, which are fixed by adhesive on the inner side of the first positioning frame 204 and the second positioning frame 205, avoid damaging the surface of the frame and enhance the friction by means of the anti-slip texture on the inner surface, ensuring that the frame is stably restricted on the template body 1. Subsequently, pressing is performed. Component 3 begins operation: The power of the pressing device body 301 is transmitted through the bolt-fixed fixing plate 302. Two symmetrically arranged columns (support frames 303) support the fixing plate 302 to maintain stability. The pressing device body 301 pushes the pressure plate 305 downward. At the same time, the adaptive pressure equalization component 4 works simultaneously: the pressure plate 305 drives the bottom connecting plate 406 to move downward. The connecting plate 406 pulls the guide rod 407. The guide rod 407 then drives the slider 404 to slide within the slide rail 402 of the copper heat-conducting plate 401. The copper heat-conducting plate 401 not only has stamped protrusions on its lower surface that are adapted to the shape of the new energy seat frame, but also has cooling channels inside (the inlet and outlet of the cooling channels extend to the outside of the template body 1, which can quickly guide away the stamped protrusions). (The heat generated by the pressure prevents the skeleton material from deforming due to overheating). The slider 404 and the fixed block 403 are respectively connected to the adjacent nodes of the telescopic rhomboid or polygonal linkage frame 405 composed of multiple hinged linkage units. The linkage frame 405 will extend and retract with the movement of the slider 404, thereby automatically adjusting the pressure distribution of the pressing component 3 to achieve uniform pressing of the skeleton. In addition, the two ends of the second spring 408 abut against the connecting plate 406 and the sliding sleeve 409 respectively. The sliding sleeve 409 and the sliding rod 410 are in clearance fit. The second spring 408 can use its own elasticity to further buffer the pressing force, so that the pressure is transmitted to various parts of the skeleton more gently and evenly. The advantage of this component linkage is that the positioning component 2 uses a U-shaped frame structure and multiple symmetrically distributed components. The springs and textured silicone pads 207 improve the positioning accuracy of the frame and protect the frame surface from damage. They can also be adapted to frame blanks of different specifications. The pressing assembly 3, relying on the stable support of the column and the bolted fixing plate 302, provides sufficient and stable power for the stamping process. The adaptive pressure equalization assembly 4, with the thermal management capability of the copper heat-conducting plate 401, the adaptive pressure adjustment function of the telescopic polygonal connecting rod frame 405, and the buffering effect of the second spring 408, the sliding sleeve 409, and the sliding rod 410, ensures high surface accuracy and uniform stress distribution of the new energy seat frame after stamping, effectively reducing the scrap rate, extending the service life of the mold and equipment, and ultimately significantly improving production efficiency and product quality.This allows the device to better adapt to the diverse and high-precision stamping requirements of new energy vehicle seat frames.

[0031] Working principle: When stamping the new energy seat frame, the positioning component 2 is first activated: the motor 201 drives the connecting rod 202 to rotate through the coupling. Since the movable rod 203 and the connecting rod 202 are movably connected, the connecting rod 202 can drive the movable rod 203, thereby driving the first positioning frame 204 and the second positioning frame 205, which have a U-shaped structure, to move. At this time, at least two first springs 206, symmetrically distributed between the first positioning frame 204 and the second positioning frame 205, use elasticity to achieve adaptive buffering, so that the two can firmly clamp the new energy seat frame blank. At the same time, the silicone pads 207, which are fixed by adhesive on the inner side of the first positioning frame 204 and the second positioning frame 205, with their anti-slip texture, not only avoid damaging the surface of the frame, but also increase the stability of the frame. Strong friction ensures the frame is stably constrained on the template body 1. Subsequently, the pressing assembly 3 begins to operate: the power of the pressing device body 301 (such as a hydraulic drive cylinder or servo electric cylinder) is transmitted through the bolt-fixed fixing plate 302. Two symmetrically arranged columns (support frames 303) support the fixing plate 302 to maintain stability. The pressing device body 301 pushes the pressure plate 305 downward. At the same time, the adaptive pressure equalization assembly 4 works synchronously: the pressure plate 305 drives the bottom fixed connecting plate 406 to move downward. The connecting plate 406 pulls the guide rod 407, and the guide rod 407 in turn drives the slider 404 to slide in the slide rail 402 of the copper heat-conducting plate 401. The copper heat-conducting plate 401 not only has stamped protrusions on its lower surface that are adapted to the shape of the new energy seat frame, but also... Furthermore, the interior is equipped with cooling channels (the inlet and outlet of the cooling channels extend to the outside of the template body 1, which can quickly conduct away the heat generated by stamping and prevent the skeleton material from deforming due to overheating). The slider 404 and the fixed block 403 are respectively connected to the adjacent nodes of the telescopic rhomboid or polygonal linkage frame 405 composed of multiple hinged linkage units. The linkage frame 405 will extend and retract with the movement of the slider 404, thereby automatically adjusting the pressing pressure distribution and achieving uniform pressing of the skeleton. In addition, the two ends of the second spring 408 abut against the connecting plate 406 and the sliding sleeve 409 respectively. The sliding sleeve 409 and the sliding rod 410 are in clearance fit. The second spring 408 can use its own elasticity to further buffer the pressing force, so that the pressure is transmitted to various parts of the skeleton more gently and evenly. The advantages of this component linkage are as follows: Positioning component 2, through its U-shaped frame structure, multiple symmetrically distributed first springs 206, and anti-slip textured silicone pads 207, not only improves the positioning accuracy of the frame but also protects the frame surface from damage. It can also adapt to frame blanks of different specifications. Pressing component 3, relying on the stable support of the column and the bolted fixing plate 302, provides sufficient and stable power for the stamping process. Adaptive pressure equalization component 4, utilizing the thermal management capability of the copper heat-conducting plate 401, the adaptive pressure adjustment function of the extendable polygonal connecting rod frame 405, and the buffering effect of the second spring 408, sliding sleeve 409, and sliding rod 410, ensures high surface accuracy and uniform stress distribution after stamping of the new energy seat frame, effectively reducing the scrap rate.This also extends the service life of molds and equipment, ultimately significantly improving production efficiency and product quality, enabling the device to better meet the diverse and high-precision stamping requirements of new energy vehicle seat frames.
