Description

Technical Field

[0001] The present invention relates to the technical field of computer case processing, and in particular to a device and process for stamping a heat dissipation side plate of a computer case. Background Art

[0002] The heat dissipation side panels of a computer case are usually designed with heat dissipation holes or a heat dissipation fan to improve the heat dissipation performance inside the case.

[0003] Computer case cooling side panels are manufactured using a stamping process. In actual production, these panels often have complex structural features, such as densely packed cooling holes and component assembly slots of varying sizes. These features require different molds to ensure precision and quality.

[0004] In the existing technology, it is necessary to divide the rolled metal plates into equal intervals based on the size of the heat dissipation side panels of the computer case. After the division is completed, the plates are transferred to the stamping die for stamping by a robot. In order to ensure the stability and accuracy of the stamping process, it may be necessary to design multiple molds to perform stamping in sections or steps. Therefore, after the stamping of one process is completed, it is necessary to use a robot to transfer it to the next stamping process. This not only reduces the stamping efficiency, but also easily causes deviations during the transfer process, which in turn affects the accuracy of subsequent stamping processing and makes the product defective rate high. Summary of the Invention

[0005] The purpose of the present invention is to provide a computer case heat dissipation side panel stamping processing device and process to solve the following technical problems: Currently, different stamping dies are used to process the sheets in steps.

[0012] Preferably, the first guide wheel is arranged on one side of the first positioning seat in a rotatable manner, and the second guide wheel is arranged on one side of the second positioning seat in a rotatable manner; Among them, the first adjustment part includes a guide mechanism, and the second adjustment part includes a guide mechanism. When the driving part drives the clamping plate to translate, the guide mechanism of the first adjustment part is used to adjust the distance between the first guide wheels on both sides, and the guide mechanism of the second adjustment part is used to adjust the distance between the second guide wheels on both sides.

[0013] Preferably, each group of the guide mechanisms includes two groups of first horizontal guide plates arranged in parallel, a second horizontal guide plate is arranged in parallel on the side away from each other of the two groups of first horizontal guide plates, a baffle is arranged vertically and fixedly on the end of the first horizontal guide plate away from the stamping die set, the baffle is close to one side of the second horizontal guide plate, and a gap is reserved between the baffle and the second horizontal guide plate for adjusting the distance between the guide wheels; Among them, one end of the first horizontal guide plate that is close to the stamping die group is fixed to an inclined guide plate that is inclined toward the second horizontal guide plate, and the other end of the inclined guide plate is fixed to the second horizontal guide plate. A first slot is provided at one end of the inclined guide plate that is close to the second horizontal guide plate, and a convex plate for supporting the movement of the guide wheel is fixedly arranged on the slot wall of the first slot. A second slot is provided at one end of the second horizontal guide plate that is close to the inclined guide plate, and a support shaft is rotatably arranged in the second slot, and four groups of limit plates are fixed on the support shaft, and the support shaft is fixed to a ratchet arranged on the outside of the inclined guide plate.

[0014] Preferably, the first pressing plates are fixedly arranged on both sides of the first clamping plate facing the stamping die set, and the second pressing plates are fixedly arranged on both sides of the second clamping plate facing the stamping die set.

[0015] A computer case heat dissipation side panel stamping process, applied to the above-mentioned computer case heat dissipation side panel stamping device, comprises the following steps: The metal coil to be processed is output through the unwinding module; The feeding module transports the metal plates in intervals based on the size of the chassis heat dissipation side panel being processed, and the length of the metal plates transported is consistent with the size of the chassis heat dissipation side panel. After one-time conveying is completed, the first stamping part, the second stamping part and the third stamping part perform a stamping process on the metal plate; The cutting section completes one-step cutting of the stamped metal sheet to form the chassis heat dissipation side panel body.

[0016] Beneficial effects of the present invention: (1) After the metal plate of the present invention is unwound and output by the unwinding module, the feeding module conveys the metal plate at intervals based on the size of the processed chassis heat dissipation side panel body, and the conveyed length is consistent with the length of the size of the chassis heat dissipation side panel body. After one conveying is completed, the first stamping part, the second stamping part and the third stamping part perform a stamping process on the metal plate. At the same time, the cutting part completes a cutting of the stamped metal plate to stamp out a group of chassis heat dissipation side panel bodies. Compared with the prior art in which the metal plate is pre-cut and then the cut metal plate is transferred to different stamping dies for stamping by several groups of manipulators, the present invention integrates several stamping parts and cutting parts, and conveys the unwound metal plate at equal intervals by setting a feeding module. After one stamping is completed, there is no need to use a manipulator to transfer the metal plate. This not only improves the stamping efficiency, but also ensures the stamping accuracy of each stamping part, avoids the phenomenon of deflection during the transfer process, and further improves the production quality. (2) In the process of feeding, the present invention first clamps and fixes the metal plate by the first clamping part, and at this time, the second clamping part and the metal plate are in a state of separation from each other. Secondly, the first clamping part is driven by the driving part to move in the direction of the stamping die set. During this process, the driving part can drive the second clamping part to move in the direction away from the stamping die set. When the first clamping part drives the metal plate to move a distance of the length of the chassis heat dissipation side plate body, the second clamping part moves to the initial position of the first clamping part. Accordingly, the stamping die set can perform a stamping process on the metal plate. During this process, the second clamping part clamps and fixes the metal plate, and the first clamping part and the metal plate are away from each other. The first clamping part moves in the opposite direction, and the second clamping part is driven by the driving part to drive the metal plate to move toward the stamping die group. The first clamping part moves in the opposite direction. The alternating movement of the clamping parts is repeated in this way, and the metal plates can be transported at equal distances. Accordingly, the present invention saves the time taken by the clamping parts to retreat after feeding forward compared to setting one clamping part. At the same time, since the present invention provides a feeding buffer zone, if only one clamping part is provided, during the process of retreating the clamping parts after feeding, the metal plate at the feeding buffer zone will be pulled back by gravity under the action of gravity, thereby affecting the normal feeding and stamping. (3) In the process of driving the clamping part to move, the driving part of the present invention can automatically adjust the distance between the guide wheel and the clamping plate based on the setting of the guide mechanism to achieve clamping of the metal plate or separation from the metal plate. There is no need to set up other servo drive equipment to adjust the distance between the clamping plates. During the feeding process, the effect of automatically adjusting the distance between the clamping plates can be achieved, and the stability and synchronization are higher.

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] Example 1 See also Figure 1-Figure 2 As shown, the present invention is a computer case heat dissipation side panel stamping processing device, including a reeling module 1 for outputting metal plates and a stamping module 3; specifically, this embodiment can output the metal coil 103 to be processed through the reeling module 1, so as to facilitate subsequent stamping processing through the stamping module 3.

[0022] It should be noted that the metal coil 103 of this embodiment is made of aluminum alloy or cold-rolled carbon steel, and has a thickness of 1 mm to 2 mm. Correspondingly, other metal materials may also be used, and this embodiment does not limit this.

[0023] In this embodiment, the stamping die set 3 includes a first stamping portion 302, a second stamping portion 303, a third stamping portion 304 and a cutting portion 305 arranged in sequence; it should be noted that after the metal plate 6 is output by the unwinding die set 1, it can pass through the first stamping portion 302, the second stamping portion 303 and the third stamping portion 304 in sequence. Each set of stamping portions can stamp the metal plate into different structural features. After the stamping is completed, it can be cut by the cutting portion 305 to form the chassis heat dissipation side panel body 6 (see Figure 7 ); For example, the chassis heat dissipation side panel body 6 of this embodiment includes a heat dissipation area 601, an assembly area 602 and a positioning area 603. These three structural features can be formed by punching the first stamping part 302, the second stamping part 303 and the third stamping part 304 respectively. The specific stamping order is not limited to meet the actual stamping processing requirements.

[0024] Accordingly, based on different production needs, the stamping die set 3 is not limited to the three groups of stamping parts provided in this embodiment, and multiple groups can also be provided without any relative specific number, so long as the actual production needs are met.

[0025] As a further solution of this embodiment, in order to ensure that the size of each set of chassis heat dissipation side panel bodies 6 is consistent, a feeding module 2 is further arranged between the unwinding module 1 and the stamping module 3, and the feeding module 2 is used to convey the metal plate after unwinding to the stamping module 3 at equal intervals; it can be explained that after the metal plate is unwound and output by the unwinding module 1, the feeding module 2 conveys the metal plate at intervals based on the size of the processed chassis heat dissipation side panel body 6, and the conveyed length is consistent with the length of the size of the chassis heat dissipation side panel body 6. After one conveying is completed, the first stamping part 302, the second stamping part 303 and the third stamping part 304 perform a stamping process on the metal plate, and at the same time, the cutting Part 305 completes a cutting of the stamped metal plate to stamp out a group of chassis heat dissipation side panel bodies 6. Compared with the prior art in which the metal plate is cut in advance and then the cut metal plate is transferred to different stamping dies for stamping by several groups of manipulators, this embodiment integrates several stamping parts with the cutting part 305, and arranges a feeding module 2 to transport the unrolled metal plate at equal intervals. After one stamping is completed, there is no need to use a manipulator to transfer the metal plate, which not only improves the stamping efficiency, but also ensures the stamping accuracy of each stamping part, avoids the phenomenon of deflection during the transfer process, and further improves the production quality.

[0026] In this embodiment, please refer to Figure 1-Figure 2 The unwinding module 1 includes a roller 102 for carrying a metal coil 103, and the roller 102 is fixedly connected to the output end of a servo motor 104; specifically, the roller 102 is rotatably arranged on the carrying box, and can be driven to rotate by the servo motor 104; It should be noted that the metal coil 103 to be processed is positioned and fixed on the roller 102, and the servo motor 104 is started to drive the roller 102 to rotate. The roller 102 can synchronously drive the metal coil 103 to rotate to achieve the unwinding effect.

[0027] Furthermore, since the wound metal sheet itself has a certain elastic force, in order to ensure the stability of unwinding and output, in this embodiment, a plurality of guide mechanisms 7 for outputting the metal sheet are provided on the carrying box. Each guide mechanism 7 includes a rotatably arranged outer guide roller 105 and an inner guide roller 106. A guide gap for rolling out the metal sheet is formed between the outer guide roller 105 and the inner guide roller 106. The metal sheet can be output through the guide gap of each guide mechanism 7 in sequence, thereby ensuring stability and safety during unwinding. In addition, during the unwinding and outputting process of the metal coil 103, when the unwinding speed is lower than the feeding speed of the feeding module 2, the pulling force of the feeding module 2 will cause creases to form on the metal plate at the guide roller, causing the metal plate to be in a non-horizontal state, thereby affecting the subsequent normal stamping. Therefore, a feeding buffer zone 101 is further provided between the unwinding module 1 and the feeding module 2; specifically, by providing the feeding buffer zone 101, the operator can observe the state of the metal plate at the feeding buffer zone 101 in real time. When the metal plate tends to be straightened, the unwinding speed of the unwinding module 1 can be accelerated, and vice versa, its unwinding speed can be reduced, so that the unwinding and feeding can always remain in a stable state.

[0028] Example 2 Based on Example 1, please refer to Figure 4 and Figure 6 The feeding module 2 includes a first clamping part 4 and a second clamping part 5 for clamping the metal plate, wherein the feeding module 2 also includes a driving part, which is used to drive the first clamping part 4 and the second clamping part 5 to reciprocate in opposite directions; it can be explained that in the feeding process, the metal plate is first clamped and fixed by the first clamping part 4, at which time the second clamping part 5 and the metal plate are in a state of separation from each other, and then the first clamping part 4 is driven by the driving part to move toward the direction of the stamping die 3. During this process, the driving part can drive the second clamping part 5 to move in a direction away from the stamping die 3. When the first clamping part 4 drives the metal plate to move a distance of the length of the chassis heat dissipation side panel body 6, the second clamping part 5 moves to the initial position of the first clamping part 4, and accordingly, the stamping die 3 can stamp the metal plate once. During this process, the second clamping part 5 clamps and fixes the metal plate, the first clamping part 4 and the metal plate move away from each other, and then the second clamping part 5 is driven by the driving part to drive the metal plate to move toward the stamping die 3, and the first clamping part 4 moves in the opposite direction. The alternating movement of the clamping parts is repeated in this way to achieve equidistant transportation of the metal plate; accordingly, this embodiment saves the time occupied by the clamping part when retreating after feeding forward compared to setting one clamping part, and can improve the feeding efficiency. At the same time, since the feeding buffer 101 is set in this embodiment, if only one group of clamping parts is set, when the clamping part retreats after feeding, the metal plate at the feeding buffer 101 will pull the metal plate at the stamping die 3 back under the action of gravity, thereby affecting normal feeding and stamping.

[0029] In this embodiment, please refer to Figure 4 as well as Figures 8-10The first clamping part 4 includes a first clamping plate 402 symmetrically arranged on both sides of the metal plate, and the first positioning seats 405 are fixedly arranged on the opposite side ends of the two groups of first clamping plates 402, and the second clamping part 5 includes a second clamping plate 501 symmetrically arranged on both sides of the metal plate, and the second positioning seats 504 are fixedly arranged on the opposite side ends of the two groups of second clamping plates 501, wherein the two groups of first positioning seats 405 are connected to the first adjusting part that drives them to approach or move away synchronously, and the two groups of second positioning seats 504 are connected to the second adjusting part that drives them to approach or move away synchronously; it can be explained that the first adjusting part of this embodiment can synchronously drive the first clamping plates 402 on both sides to approach or move away from each other through the first positioning seat 405, and the second adjusting part can synchronously drive the second clamping plates 501 on both sides to approach or move away from each other through the second positioning seat 504.

[0030] In addition, it should be noted that the first positioning seat 405 is arranged at one end of the first clamping plate 402, and the second positioning seat 504 is arranged at one end of the second clamping plate 501 away from the first positioning seat 405; specifically, by staggering the first adjustment part and the second adjustment part, when the driving part drives the first clamping part 4 and the second clamping part 5 to move, interference between the adjustment parts on both sides is avoided.

[0031] As a further solution of this embodiment, please refer to Figures 8-10 The first adjusting part includes a U-shaped frame 801, and the second adjusting part includes a U-shaped frame 801. The two side plates of the U-shaped frame 801 are respectively slidably provided with clamping rods 802 fixed to the positioning seat, and the clamping rods 802 are provided with a telescopic spring 8; specifically, the telescopic spring 8 of this embodiment is in a contracted state, so it can drive the clamping rods 802 on both sides to slide toward each other under the action of elastic force, and the clamping rods 802 on both sides can drive the positioning seats and the clamping plates on both sides to approach each other, thereby clamping the metal plate. When the adjusting part drives the clamping plates on both sides to move away from each other, the telescopic spring 8 can be further compressed.

[0032] For details, please refer to Figure 4 as well as Figure 6The driving part includes a conveyor belt mechanism 202, which is sleeved on a plurality of conveyor rollers 205. The conveyor rollers 205 are connected to a servo drive device to drive the conveyor belt mechanism 202 to and fro. The conveyor belt mechanism 202 includes an upper horizontal belt 203 and a lower horizontal belt 204. The upper horizontal belt 203 and the lower horizontal belt 204 are parallel to each other. For the first adjustment part, the U-shaped frame 801 is fixed to the first positioning plate 401 fixedly arranged on the upper horizontal belt 203. For the second adjustment part, the U-shaped frame 801 is fixed to the first positioning plate 401 fixedly arranged on the lower horizontal belt 204. The second positioning plate 505 is fixedly connected; it can be explained that when the driving part drives the first clamping part 4 and the second clamping part 5 to reciprocate in opposite directions, the driving part can first drive the conveying roller 205 to rotate reciprocatingly through the servo driving device, and the conveying roller 205 can drive the conveyor belt mechanism 202 to convey back and forth. Since the two groups of U-shaped frames 801 are respectively arranged on the upper horizontal belt 203 and the lower horizontal belt 204, when the conveyor belt mechanism 202 moves in one direction, the movement directions of the two groups of U-shaped frames 801 remain opposite, and then the first clamping part 4 and the second clamping part 5 can be driven to move in opposite directions.

[0033] In this embodiment, please refer to Figures 8-11 , the first guide wheel 403 is arranged on one side of the first positioning seat 405 and the second guide wheel 503 is arranged on one side of the second positioning seat 504, wherein the first adjustment part includes a guide mechanism 7 and the second adjustment part includes a guide mechanism 7. When the driving part drives the clamping plate to translate, the guide mechanism 7 of the first adjustment part is used to adjust the distance between the first guide wheels 403 on both sides, and the guide mechanism 7 of the second adjustment part is used to adjust the distance between the second guide wheels 503 on both sides; it can be explained that when the first clamping part 4 is in a state of clamping and fixing the metal plate, the first guide wheels 403 on both sides are at this time. The spacing is the smallest, and the spacing between the second guide wheels 503 on both sides is also the smallest. However, as the driving unit drives the first clamping part 4 to move toward the direction of the stamping die 3, the guide mechanism 7 can drive the second guide wheels 503 on both sides to move away from each other, that is, adjust the second clamping plates 501 on both sides to move away from each other. As the driving unit drives the first clamping part 4 to convey the metal plate to a preset length, the positions of the first clamping part 4 and the second clamping part 5 are exchanged. At this time, the guide mechanism 7 drives the second guide wheels 503 on both sides to move closer to each other to clamp and fix the metal plate again. This reciprocating process can achieve the effect of alternating equidistant conveying. For details, please refer to Figure 10-14Each guide mechanism 7 includes two sets of first horizontal guide plates 701 arranged in parallel. The two sets of first horizontal guide plates 701 are fixed to each other. The second horizontal guide plates 703 are arranged in parallel on the side away from each other. The end of the first horizontal guide plate 701 away from the stamping die 3 is vertically fixed with a baffle 704. The baffle 704 leans against the side of the second horizontal guide plate 703. A gap 710 for adjusting the distance between the guide wheels is reserved between the baffle 704 and the second horizontal guide plate 703. Among them, the end of the first horizontal guide plate 701 leaning against the stamping die 3 and the end facing the second horizontal The inclined guide plate 702 is fixed to the guide plate 703, and the other end of the inclined guide plate 702 is fixed to the second horizontal guide plate 703. The first notch 709 is formed at one end of the inclined guide plate 702 that is close to the second horizontal guide plate 703. A convex plate 708 for supporting the movement of the guide wheel is fixedly arranged on the groove wall of the first notch 709. The second horizontal guide plate 703 is close to one end of the inclined guide plate 702 that is close to the inclined guide plate 702. A second notch 705 is formed in the second notch 705. A support shaft 707 is rotatably arranged in the second notch 705. Four sets of limit plates 706 are fixed on the support shaft 707. The support shaft 707 is arranged on the outside of the inclined guide plate 702. When the cam 711 is in the closed position, the cam 712 is in the closed position, and the cam 713 is in the closed position, so that the cam 713 can be adjusted to the desired position. When the cam 713 is in the closed position, the cam 713 is adjusted to the desired position, so that the cam 713 can be adjusted to the desired position. 0 degrees, at this time the guide wheel moves to above the second notch 705, and the next set of limiting plates 706 rotates into the second notch 705. Since the support shaft 707 is connected to the ratchet 711, it cannot rotate in the opposite direction, and the guide wheel can be supported by the set of limiting plates 706. Therefore, when the driving unit drives the clamping plate to move in the opposite direction, the guide wheel can move along the second horizontal guide plate 703 in the direction away from the stamping die 3. When the guide wheel moves to the notch 710, based on the setting of the telescopic spring 8, the guide wheel can be pushed to contact the first horizontal guide plate 701 under the action of the elastic force, and so on. It should be noted that, in the process of driving the clamping part to move, the driving part of this embodiment can automatically adjust the distance between the guide wheel and the clamping plate based on the setting of the guide mechanism 7 to achieve clamping of the metal plate or separation from the metal plate. This embodiment does not require the setting of other servo drive equipment to adjust the distance between the clamping plates. During the feeding process, the effect of automatically adjusting the distance between the clamping plates can be achieved, and the stability and synchronization are higher.

[0034] In addition, see Figure 2 and Figure 12In order to fix each guide plate, the baffle 704 at the end of the second horizontal guide plate 703 is fixed to the mounting frame 206, and each conveying roller 205 is also rotated and arranged on one side of the mounting frame 206 through the bracket, and the mounting frame 206 is fixed on the base frame 201.

[0035] See also Figure 9 The first clamping plate 402 is fixed with the first pressing plate 404 on both sides of the stamping die 3, and the second clamping plate 501 is fixed with the second pressing plate 502 on both sides of the stamping die 3; it can be explained that the clamping plate of this embodiment can not only improve the tightness of the crimping by setting two sets of pressing plates while clamping the metal plate, but also, since the pressing plate is usually set to a certain length, the metal plate can be flattened to improve the subsequent stamping accuracy.

[0036] See also Figure 3 Two groups of guide plates 107 are also arranged on the side of the buffer zone 101 close to the feeding module 2. Several groups of guide wheels 108 are rotated and arranged on the side close to the two groups of guide plates 107. A gap for passing the metal plate is formed between the two groups of guide wheels 108; specifically, the unwound metal plate can be transported through the gap between the two groups of guide wheels 108, which on the one hand improves the transportation stability and on the other hand can level the metal plate.

[0037] In addition, see Figure 5 The first stamping part 302, the second stamping part 303 and the third stamping part 304 all include an upper mold 306 and a lower mold 307 fixedly arranged on the base 301.
