Description

Technical Field

[0001] This application relates to the field of stamping equipment technology, and in particular to a PCM phase change material cutting stamping device. Background Technology

[0002] Currently, phase change materials (PCMs) are typically formed from graphene composites, exhibiting high hardness and a degree of brittleness. They are prone to powder shedding during cutting and processing, causing severe wear on cutting tools. Existing PCM products are usually prepared into thin sheets by lamination or coating, with a single sheet thickness of 2mm. By stacking two 2mm thick sheets, a PCM pad with a target thickness of 4mm is formed.

[0003] In existing processing technology, PCM materials are generally cut using engraved spring molds. Since the blades of this type of mold can only cut downwards from one side of the material, it is difficult to achieve one-time forming when the material thickness reaches 4mm. Therefore, in current production, 4mm thick PCM materials can usually only be processed in layers, that is, two 2mm thick single-layer materials are punched twice, and then the two semi-finished products are stacked and bonded together manually to form the final product, which leads to a reduction in production efficiency. Utility Model Content

[0004] The technical problem to be solved by this application is to provide a PCM phase change material cutting and stamping device to address the above-mentioned deficiencies of the prior art and improve production efficiency.

[0005] The technical solution adopted by this application to solve the technical problem is as follows: A PCM phase change material cutting and stamping apparatus, comprising: Two template units are arranged vertically and opposite to each other; The driving unit is connected to two template units respectively and is used to drive the two template units to move towards or away from each other; Two cutting units are respectively set on the two template units to cut the PCM phase change material from top to bottom; An elastic support unit is disposed within the template unit and can extend and retract in the vertical direction; in its natural state, the end of the elastic support unit extends out of the cutting unit.

[0008] In the PCM phase change material cutting and stamping device, the difference between the height of the limiting boss extending beyond the die and the height of the blade extending beyond the die is in the range of 0.013mm to 0.016mm.

[0009] The PCM phase change material cutting and stamping device, wherein the elastic support unit includes: A transmission plate is disposed inside the die-cutting mold and can reciprocate relative to the die-cutting mold in the vertical direction; An elastic feeding component is disposed within the template unit, with one end extending into the die and connected to the transmission plate; A spring block assembly is disposed within the die-cutting mold and located on the side of the transmission plate away from the elastic pusher assembly; one end of the spring block assembly is connected to the transmission plate, and the other end extends toward the surface; in its natural state, the end of the spring block assembly away from the transmission plate extends beyond the surface.

[0010] The PCM phase change material cutting and stamping device further includes: The through groove is partially located on the template unit and partially on the die-cutting mold; the transmission plate and the elastic pusher assembly are both located within the through groove; in its natural state, the transmission plate is in contact with the inner wall of the through groove.

[0011] The PCM phase change material cutting and stamping device, wherein the elastic pusher assembly includes: Multiple springs, evenly arranged; The limiting rod is located inside the spring and is connected to the template unit and the transmission plate, respectively.

[0014] The PCM phase change material cutting and stamping device further includes: Multiple guide posts are provided on one of the template units; another template unit is provided with a plug-in slot, which corresponds to and cooperates with the guide posts.

[0015] Beneficial effects: Compared to existing technologies that require cutting and then bonding, and involve two separate cuts, this application uses two vertically distributed cutting units. The two layers of material are first bonded together to form a 4mm integral material. Then, the cutting can proceed simultaneously from both sides of the material, changing the cutting stress from single-sided concentration to double-sided dispersion. During slitting, each cutting unit only cuts 2mm, requiring only one cut, thus avoiding the need for two cutting steps and improving production efficiency. Furthermore, the elastic support unit provides partial elastic energy absorption before the cutting unit contacts the material, reducing the direct impact between the cutting unit and the hard PCM phase change material, thereby reducing tool fatigue and wear, and extending tool life.

[0019] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0020] This application provides a PCM phase change material cutting and stamping device, such as... Figure 1 and Figure 2 As shown, the PCM phase change material cutting and stamping device includes: two template units 1, two cutting units 2, a driving unit, and an elastic support unit 3; the two template units 1 are arranged vertically and opposite to each other; the driving unit is connected to the two template units 1 respectively and is used to drive the two template units 1 to move towards or away from each other; the two cutting units 2 are respectively disposed on the two template units 1 to cut the PCM phase change material vertically; the elastic support unit 3 is disposed inside the template unit 1 and can extend and retract vertically; in its natural state, the end of the elastic support unit 3 extends out of the cutting unit 2.

[0021] Specifically, two template units 1 are arranged facing each other, one above the other, and each template unit 1 is provided with a cutting unit 2, and the two cutting units 2 are arranged along the same vertical line; the driving unit drives the two template units 1 to move towards each other, so that the two cutting units 2 can act on the PCM phase change material at the same time, thereby cutting the PCM phase change material from the top and bottom sides at the same time; the driving unit is also used to drive the two template units 1 to move away from each other, so that the two cutting units 2 separate from each other, thereby allowing the cut PCM phase change material to be removed.

[0022] Compared to existing technologies that require cutting and then bonding, and involve two separate cutting processes, this application uses two vertically distributed cutting units 2. After the two layers of material are bonded together to form a 4mm thick integral material, cutting can proceed simultaneously from both sides. This transforms the cutting stress from single-sided concentration to double-sided dispersion. During the cutting process, each cutting unit 2 only cuts 2mm in, requiring only one cut, thus avoiding the need for two separate cutting steps and improving production efficiency. Furthermore, existing technologies require cutting two 2mm thick materials before manual alignment and bonding. The small area of ​​the cut material makes edge misalignment during manual alignment prone to occur, which can lead to dimensional deviations for products with high tolerance requirements during subsequent assembly, making it difficult to guarantee product shape accuracy and consistency. In contrast, this application utilizes a different approach. Figure 6 As shown, in this application, two 2mm thick materials 100 can be bonded together with double-sided tape 200 before cutting to form a 4mm thick material before punching. That is, in this application, the entire material is bonded together, which makes it easier to align and reduces the risk of misalignment. In addition, the upper and lower layers of material are subjected to force simultaneously during cutting, and the cut line is consistent, further reducing the risk of misalignment between layers.

[0023] There are two elastic support units 3, one of which is provided in each template unit 1; the elastic support unit 3 can elastically expand and contract in the vertical direction; in its natural state, when no PCM phase change material is arranged between the two cutting units 2, such as Figure 1 As shown, the ends of the two elastic support units 3 extend out of the corresponding cutting units 2. That is, the lower end of the upper elastic support unit 3 extends downward beyond the upper cutting unit 2, and the upper end of the lower elastic support unit 3 extends upward beyond the lower cutting unit 2. Therefore, when the material to be cut is fed between the two cutting units 2, the material to be cut first contacts the elastic support unit 3, rather than directly contacting the cutting unit 2. This avoids the material being scratched by the cutting unit 2 during positioning or feeding, and also prevents the material from being embedded in the cutting unit 2 in advance, which would cause the mold to jam.

[0024] When the two template units 1 move towards each other and cut the material, under pressure, the material to be cut first compresses the elastic support unit 3, and both elastic support units 3 undergo compressive deformation, such as... Figure 2As shown, the ends of the two elastic support units 3 are compressed into the corresponding cutting unit 2; then the cutting unit 2 cuts into the material to achieve a flat cut. The elastic support unit 3 plays a role in buffering and pressing the material, so that the material does not warp or slip, and avoids the material from being deformed by impact during cutting, thus ensuring a straight cut.

[0025] After cutting, as the two template units 1 move away from each other, and the pressure decreases, the ends of the two elastic support units 3 extend out of the corresponding cutting unit 2 again, thereby lifting the material so that the cut material can be removed from the cutting unit 2, avoiding jamming and facilitating automatic material discharge.

[0026] The PCM phase change material cutting and punching device in this application can not only cut 4mm thick PCM phase change material from top to bottom at the same time, but also provide some elastic energy absorption through the elastic support unit 3 before the cutting unit 2 contacts the material, thereby reducing the direct impact between the cutting unit 2 and the hard PCM phase change material, thus reducing tool fatigue and wear, and extending tool life.

[0027] In this application, the drive unit can be installed and positioned via a worktable or a robotic arm. The drive unit can utilize existing technology, requiring only that it can drive the two template units 1 to achieve opposite and opposite movements of the two cutting units 2. For example, each template unit 1 can be connected to a corresponding cylinder, with the cylinder piston connected to the template unit 1, and the extension and retraction directions of the pistons of the two cylinders being opposite. Since the drive unit uses existing technology, its structure will not be described in detail here.

[0028] One embodiment of this application, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cutting unit 2 includes a die 21 and a blade 22; the die 21 is partially embedded in the template unit 1; the blade 22 is disposed on the surface of the die 21 facing away from the template unit 1. Specifically, the dies 21 of the two cutting units 2 are arranged opposite to each other, and the blades 22 are also arranged opposite to each other; the end of the elastic support unit 3 extends beyond the blade 22 to ensure that the material to be cut contacts the elastic support unit 3 first, rather than the blade 22, during feeding.

[0029] In one embodiment of this invention, the cutting unit 2 further includes two limiting bosses 4, both of which are disposed on the die 21 and are located on the same side as the blade 22; the blade 22 is located between the two limiting bosses 4; the height of the limiting bosses 4 extending beyond the die 21 is greater than the height of the blade 22 extending beyond the die 21.

[0030] Specifically, for a cutting unit 2, there are two limiting bosses 4, which are symmetrically arranged on the same side of the die 21; the blade 22 is located between the two limiting bosses 4, and the height of the limiting bosses 4 beyond the die 21 is greater than the height of the blade 22 beyond the die 21; when the upper and lower aligned limiting bosses 4 are in contact, the two upper and lower aligned blades 22 are not in contact, but a certain gap is maintained.

[0031] During cutting, as the two cutting units 2 approach each other, the end of the elastic support unit 3 is gradually compressed into the die 21, and the limiting bosses 4 of the upper and lower cutting units 2 gradually approach each other. When the two cutting units 2 are closed, the limiting bosses 4 of the upper and lower cutting units 2 contact each other, and there is a gap between the upper and lower blades 22, thereby limiting the blades 22 from going deeper and ensuring that the blades 22 only shear the material and do not completely press together, avoiding direct collision between the upper and lower blades 22, which could cause the blade edge to chip or roll. That is, this application provides a mechanical limiting gap to ensure that the two aligned blades 22 always maintain a safe distance.

[0032] In one embodiment of this invention, the difference between the height of the limiting boss 4 extending beyond the die 21 and the height of the blade 22 extending beyond the die 21 ranges from 0.013mm to 0.016mm.

[0033] Specifically, the difference between the height of the limiting boss 4 extending beyond the die 21 and the height of the blade 22 extending beyond the die 21 is designed to be 0.013mm to 0.016mm. This height difference forms a precise micro-gap when the upper and lower blades 22 are closed. The cutting part does not rely on direct collision between the upper and lower blades 22, but rather on the shearing force formed by the upper and lower blades 22. The micro-gap causes strong stress concentration in the middle part of the material, prompting cracks to propagate along the stress line, thereby achieving smooth fracture of the material. That is, the material fractures smoothly under shear stress, rather than being torn or crushed by the complete contact of the upper and lower blades 22, thus avoiding burrs and cracks at the cut.

[0034] One embodiment of this application, such as Figure 4 and Figure 5 As shown, the elastic support unit 3 includes an elastic pusher assembly 31, a transmission plate 32, and a spring block assembly 33; the transmission plate 32 is disposed within the die 21 and can reciprocate vertically relative to the die 21; the elastic pusher assembly 31 is disposed within the template unit 1, with one end extending into the die 21 and connected to the transmission plate 32; the spring block assembly 33 is disposed within the die 21 and located on the side of the transmission plate 32 away from the elastic pusher assembly 31; one end of the spring block assembly 33 is connected to the transmission plate 32, and the other end extends toward the surface; as shown... Figure 4As shown, in its natural state, the end of the spring block assembly 33 that is away from the transmission plate 32 extends beyond the surface (the surface of the die 21 that is away from the template unit 1).

[0035] Specifically, the spring block assembly 33 is used to contact the material and transmit pressure from the transmission plate 32 to the elastic pusher assembly 31, so that the elastic pusher assembly 31 can be compressed under pressure, thereby providing clearance space for the spring block assembly 33 and ensuring that the spring block assembly 33 moves toward the compression direction of the elastic pusher assembly 31 until it retracts into the die 21 (e.g., Figure 5 (As shown). When the external pressure is less than the elastic force of the elastic pusher assembly 31, the elastic force of the elastic pusher assembly 31 is transmitted to the spring block assembly 33 through the transmission plate 32, thereby pushing the spring block assembly 33 out of the die 21 and beyond the limit boss 4.

[0036] In one embodiment of this invention, the PCM phase change material cutting and punching device further includes a through groove 5, a portion of which is located on the template unit 1 and a portion on the die 21; the transmission plate 32 and the elastic pusher assembly 31 are both located within the through groove 5; in its natural state, as Figure 4 As shown, the transmission plate 32 is in contact with the inner wall of the through groove 5.

[0037] Specifically, the through groove 5 serves both to provide space for the elastic support unit 3 to extend and retract, and to limit the extension of the elastic support unit 3. The transmission plate 32 and the elastic pusher assembly 31 are both located within the through groove 5; one end of the spring block assembly 33 is located within the through groove 5 and connected to the transmission plate 32, while the other end (i.e., the end of the elastic support unit 3) passes through the through groove 5 and the die 21 in sequence, thus ensuring that it can extend beyond the blade 22 or retract into the die 21. Taking the upper cutting unit 2 as an example, in its natural state, the transmission plate 32 is in contact with the bottom wall of the through groove 5, and the end of the spring block assembly 33 away from the transmission plate 32 extends outside the die 21.

[0038] One implementation method in this embodiment, such as Figure 3 , Figure 4 and Figure 5 As shown, the elastic pushing assembly 31 includes multiple springs 311 and limiting rods 312; the number of limiting rods 312 is equal to that of springs 311 and they correspond one-to-one. The multiple springs 311 are evenly arranged; the limiting rods 312 are located inside the springs 311 and are respectively connected to the template unit 1 and the transmission plate 32.

[0039] Specifically, the limiting rod 312 is inside the spring 311 and is used to guide and limit the elastic extension and contraction of the spring 311, so that the elastic extension and contraction of the spring 311 is in the vertical direction, thereby ensuring that the extension and contraction of the spring block assembly 33 is a linear movement in the vertical direction and avoiding the movement of the spring block assembly 33 from being skewed.

[0040] The spring block assembly 33 includes multiple spring blocks that are evenly arranged; the die 21 is provided with multiple limiting holes that correspond one-to-one with the spring blocks; the spring blocks are located in the limiting holes and can reciprocate in the vertical direction.

[0041] In one embodiment of this invention, the number of spring blocks and springs 311 are equal and correspond one-to-one. The central axis of the spring block and the corresponding spring 311 coincides to ensure that the force is evenly distributed, thereby ensuring that the movement of the spring block is linear.

[0042] Specifically, the limiting hole extends to the inner wall of the through groove 5 near the blade 22, so that the limiting hole is connected to the through groove 5. Then, one end of the spring block is connected to the transmission plate 32 in the through groove 5, and the other end of the spring block can extend into the limiting hole. Under the guidance of the limiting hole, the spring block moves back and forth in a straight line in the vertical direction.

[0043] One embodiment of this application, such as Figures 1 to 4 As shown, the template unit 1 includes a first template 11 and a second template 12; the first template 11 is connected to the driving unit; the second template 12 is disposed on the first template 11; the die 21 is disposed on the second template 12 and is located on the side of the second template 12 away from the first template 11; the size of the second template 12 is smaller than the size of the first template 11, and the center of the second template 12 coincides with the center of the first template 11.

[0044] Specifically, the first template 11 is larger in size and is directly connected to the drive unit, bearing the main punching force and reaction force; the second template 12 is relatively smaller in size, installed on the first template 11, and used to fix the die 21; the second template 12 is positioned vertically opposite each other in the two template units 1. When high pressure is generated during the punching process, the larger first template 11 can disperse the stress and improve the overall rigidity; the second template 12 can act as an intermediate buffer to a certain extent, absorbing the instantaneous impact load when the die 21 cuts in, preventing the punching force from acting directly on the drive unit, and extending the service life of the equipment.

[0045] In one embodiment of this invention, the first template 11 and the second template 12 in the same template unit 1 can adopt an integral molding structure to improve the overall structural strength.

[0046] In one embodiment of this application, the PCM phase change material cutting and punching device further includes multiple guide posts 6, each of which is disposed on one of the template units 1. The other template unit 1 is provided with an insertion groove 7, which corresponds one-to-one with and cooperates with the guide posts 6, thereby providing guidance for the opposing and reversing movements of the two cutting units 2 and improving the cutting quality. When the upper and lower limiting bosses 4 contact each other, the guide posts 6 insert into the corresponding insertion grooves 7 and contact the bottom wall of the insertion grooves 7.

[0047] In one embodiment of this invention, the guide post 6 is disposed on the first template 11 of one template unit 1, and the corresponding insertion slot 7 is disposed on the first template 11 of another template unit 1; the size difference between the first template 11 and the second template 12 is just enough to provide clearance for the installation of the guide post 6.

[0048] In another embodiment of this invention, the guide post 6 is disposed on the second template 12 of one of the template units 1, and the corresponding insertion slot 7 is disposed on the second template 12 of the other template unit 1.

[0049] In summary, this application provides a PCM phase change material cutting and stamping device, comprising: two template units arranged vertically and opposite to each other; a driving unit connected to the two template units respectively, and used to drive the two template units to move towards or away from each other; two cutting units respectively disposed on the two template units to cut the PCM phase change material vertically; an elastic support unit disposed within the template units and capable of extending and retracting vertically; in its natural state, the end of the elastic support unit extends out of the cutting unit. Compared to existing technologies that require cutting and bonding twice, this application uses two vertically distributed cutting units. The two layers of material are first bonded together to form a 4mm integral material. Then, the cutting can proceed simultaneously from both sides of the material, changing the cutting stress from single-sided concentration to double-sided dispersion. During slitting, each cutting unit only cuts 2mm in, requiring only one cut, thus avoiding the need for two cutting steps and improving production efficiency. Furthermore, the elastic support unit provides partial elastic energy absorption before the cutting unit contacts the material, reducing direct impact between the cutting unit and the hard PCM phase change material, thereby reducing tool fatigue and wear, and extending tool life.
