Description

Technical Field

[0001] This application relates to the field of vehicle parts processing technology, and more specifically, to a stamping die and stamping system. Background Technology

[0002] With the rapid development of the automotive industry, lightweight design has become a crucial trend in automobile manufacturing. In the field of body manufacturing, the choice of materials for stamped body panels has a significant impact on the overall vehicle weight and performance. Currently, steel sheets (including galvanized sheets) and aluminum sheets are the two most commonly used materials for stamped body panels. Due to its low density and light weight, aluminum sheets have a clear advantage in achieving lightweight body construction, and therefore their application in modern automobile manufacturing is becoming increasingly prominent.

[0003] The current aluminum sheet punching process requires at least two steps: the first punching removes the two ends of the waste material, and the second punching removes the remaining waste material in the middle. This two-step process is not only inefficient and requires the development of corresponding equipment, which is costly, but also inevitably cuts the vertical wall surface of the product during the first punching. When the draft angle is less than 20°, the part is prone to tearing and will also generate debris. This debris can easily adhere to the product surface, forming indentations or bumps, which affects product quality.

[0004] Therefore, there is an urgent need to provide a stamping die and stamping system to compensate for the shortcomings of the existing technology to a certain extent. Utility Model Content

[0005] The purpose of this application is to provide a stamping die and stamping system that optimizes the die structure to a certain extent, reduces processing steps, and reduces the generation of waste during the stamping process.

[0006] To achieve the above objectives, the present invention provides a stamping die, comprising a lower die and an upper die; the lower die includes a base and a support module, the support module being disposed on the base; the upper die includes a drive mechanism and a punching module, the punching module being vertically opposite to the support module; the telescopic end of the drive mechanism is connected to the punching module to drive the punching module to move towards or away from the support module; the edge of the support module forms a continuous positioning cutting edge, and the punching module forms a punching cutting edge with the same shape as the positioning cutting edge; the product to be cut is punched between the positioning cutting edge and the punching cutting edge to form a continuous trimming line.

[0007] The stamping die provided by this utility model also includes a pushing mechanism, which is disposed on the side wall of the bearing module corresponding to the positioning cutting edge. The telescopic end of the pushing mechanism can contact the inner wall surface of the waste material and extend to push the waste material away after punching.

[0008] Specifically, the feeding mechanism includes a first feeding component and a second feeding component. The first feeding component and the second feeding component are spaced apart along the extension direction of the positioning blade, and the telescopic ends of the first feeding component and the second feeding component can both contact the inner wall surface of the waste material.

[0009] Furthermore, both the first and second pushing components include a positioning seat and a pushing member. The positioning seat is connected to the bearing module, the pushing member extends along a first direction, and the positioning end of the pushing member is connected to the positioning seat, while the telescopic end can contact the inner wall surface of the waste material.

[0010] The lower mold further includes a first guide component and a second guide component; the first guide component and the second guide component are disposed on the base and located at both ends of the positioning cutting edge, for guiding the punched waste material.

[0011] Specifically, both the first guide assembly and the second guide assembly include a mounting base, a connecting rod, and a guide plate. The mounting base is connected to the base, one end of the connecting rod is connected to the mounting base, and the other end is connected to the guide plate, which extends vertically.

[0012] Specifically, the lower mold further includes a disassembly assembly, which includes a cutter that extends along the first direction and is located below the support module.

[0013] Furthermore, the first guide assembly and the second guide assembly also include a guide rod extending along a first direction.

[0014] Furthermore, the stamping die provided by this utility model also includes a baffle, which is disposed at the end of the cutter away from the bearing module, and the baffle is set at an angle to the cutter.

[0015] Compared with the prior art, the stamping die provided by this utility model has the following advantages:

[0016] The stamping die provided by this utility model includes a lower die and an upper die. The lower die includes a base and a support module, with the support module mounted on the base. The upper die includes a drive mechanism and a punching module. The punching module and the support module are arranged opposite each other in the vertical direction. The telescopic end of the drive mechanism is connected to the punching module to drive the punching module to move towards or away from the support module. The edge of the support module has a continuous positioning cutting edge, and the punching module has a punching cutting edge with the same shape as the positioning cutting edge. The product to be cut is punched between the positioning cutting edge and the punching cutting edge to form a continuous trimming line.

[0017] Analysis shows that the lower die provides positioning for the product to be punched. The lower die in this application includes a base and a support module. The base provides installation space for the support module, which in turn supports the product to be punched. Correspondingly, the support module in this application has continuous positioning cutting edges on its edges, and the punching module of the upper die has punching cutting edges at the positions corresponding to the positioning cutting edges. The drive mechanism can drive the punching module to move towards or away from the support module. Therefore, when the product needs to be punched, the drive component drives the punching module to approach the support module. As the corresponding punching cutting edges gradually approach the positioning cutting edges, pressure can be applied to the product. Thus, the punching and cutting of the product is achieved through the shearing force between the punching cutting edges and the positioning cutting edges.

[0018] It is understandable that, since the positioning cutting edge and the punching cutting edge provided in this application are both continuous cutting edges, the punching process can be completed in only one step, thereby improving work efficiency to a certain extent. At the same time, since there are fewer scrap blades and the punching process is mainly vertical, it does not involve cutting the vertical wall surface of the product. This can avoid the generation of cutting powder, debris, and burrs during the trimming process to a certain extent, thereby reducing the quality problems such as bulges or indentations caused by debris and cutting powder adhering to the mold.

[0019] On the other hand, since the process is simpler, there is no need to develop or design other supporting molds, which can reduce the overall equipment development and maintenance costs to a certain extent.

[0020] In addition, this utility model also provides a stamping system, including a waste conveyor belt and the above-mentioned stamping die; the waste conveyor belt is used to transfer punching waste.

[0021] The stamping system using the stamping die provided in this application can quickly remove the waste material from the product, completing the process in just one step. This saves on equipment development costs, improves operational efficiency, reduces debris generation, and enhances product quality. The cut waste material can be transported by a waste conveyor belt, forming a streamlined production line operation that requires no manual intervention, ensuring a clean working environment and further improving product quality.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] like Figure 1 As shown, the stamping die provided in this application includes a lower die and an upper die. The lower die includes a base 1 and a support module 2. The support module 2 is disposed on the base 1. The upper die includes a drive mechanism and a punching module. The punching module and the support module 2 are disposed opposite each other in the vertical direction. The telescopic end of the drive mechanism is connected to the punching module to drive the punching module to move towards or away from the support module 2. The edge of the support module 2 is formed with a continuous positioning cutting edge 201. The punching module is formed with a punching cutting edge with the same shape as the positioning cutting edge 201. The product to be cut is punched between the positioning cutting edge 201 and the punching cutting edge to form a continuous trimming line.

[0032] Compared with the prior art, the stamping die provided by this utility model has the following advantages:

[0033] The stamping die provided in this application can provide positioning for the product to be stamped through the lower die. The lower die in this application includes a base 1 and a support module 2. The base 1 can provide installation space for the support module 2, and the support module 2 can be used to support the product to be stamped. Correspondingly, since the edge of the support module 2 in this application has a continuous positioning cutting edge 201, and the upper die's stamping module has a punching cutting edge at the position corresponding to the positioning cutting edge 201, and the driving mechanism can drive the punching module to move towards or away from the support module 2, when it is necessary to punch the product, the driving component drives the punching module to approach the support module 2. As the corresponding punching cutting edge gradually approaches the positioning cutting edge 201, pressure can be applied to the product, thereby realizing the stamping and cutting of the product through the shearing force between the punching cutting edge and the positioning cutting edge 201.

[0034] It is understandable that, since the positioning cutting edge 201 and the punching cutting edge provided in this application are both continuous cutting edges, the punching process can be completed in only one step, thereby improving work efficiency to a certain extent. At the same time, since there are fewer scrap blades and the punching process is mainly vertical punching, it does not involve cutting the vertical wall surface of the product. This can avoid the generation of cutting powder, debris, and burrs during the trimming process to a certain extent, thereby reducing the quality problems such as bulges or indentations caused by debris and cutting powder adhering to the mold.

[0035] On the other hand, since the process is simpler, there is no need to develop or design other supporting molds, which can reduce the overall equipment development and maintenance costs to a certain extent.

[0036] Optionally, such as Figure 1 As shown, the lower mold in this application also includes a first guide component 5 and a second guide component 6; the first guide component 5 and the second guide component 6 are disposed on the base 1 and located at both ends of the positioning cutting edge 201, for guiding the punched waste.

[0037] In actual operation, after punching, the product generates waste material, which needs to fall onto the waste conveyor belt for transfer. To prevent the waste material from falling uncontrollably after punching, this application sets a first guide component 5 and a second guide component 6 at both ends of the positioning blade 201, which can form a guide space between the first guide component 5 and the second guide component 6. This can, to a certain extent, ensure that the waste material falls onto the waste conveyor belt in a fixed direction, thereby enabling the entire operation process to form an assembly line operation.

[0038] Optionally, such as Figure 1 As shown, the first guide assembly 5 and the second guide assembly 6 in this application both include a mounting base 501, a connecting rod 502 and a guide plate 503. The mounting base 501 is connected to the base 1. One end of the connecting rod 502 is connected to the mounting base 501 and the other end is connected to the guide plate 503. The guide plate 503 extends in the vertical direction.

[0039] The mounting base 501 enables connection to the base 1, while the connecting rod 502 allows the guide plate 503 to be brought closer to the end of the positioning blade 201, thus guiding the waste material.

[0040] It should be noted that the connecting rod 502 in this application can be replaced by a telescopic structure such as a cylinder. That is, the cylinder body is connected to the mounting base 501, and one end of the telescopic rod is connected to the guide plate 503. Thus, by extending and retracting the cylinder, the guide plate 503 can be moved, and the distance between the two guide plates 503 can be adjusted according to the size of the waste generated by different product models to ensure that the waste can smoothly reach the conveyor belt.

[0041] Optionally, such as Figure 1 As shown, the lower mold in this application also includes a disassembly assembly, which includes a cutter 7 that extends along the first direction S1 and is located below the support module 2.

[0042] Since both the positioning cutting edge 201 and the punching cutting edge of this application are continuous and uninterrupted, the punched waste is a single piece of waste. Since some equipment has requirements on the size of the waste, such as excessively large waste blocks that cannot reach the waste conveyor belt for transfer, this application further sets up a decomposition component, and the decomposition component includes a cutter 7 extending along the first direction S1. It can be understood that the cutter 7 in this application is only a positioning cutter head structure with a cutting edge and fixed on the base 1. After the waste is punched and falls onto the cutter 7, the structure in the upper mold used to decompose the waste can still be used to achieve the cutting and decomposition of the waste.

[0043] It should be noted that the structure of the upper and middle molds used to decompose waste can be similar to that of the punching module. Both include a drive component that can extend and retract in the vertical direction and a decomposition module that can cooperate with the cutter 7 and also has a cutting edge to cut the waste. Thus, the waste is separated by pressing down the decomposition module in conjunction with the cutter 7.

[0044] It is understood that in this application, the cutting blade 7 being located below the support module 2 means that the horizontal height of the support module 2 in the vertical direction is such that at least the horizontal height of the positioning blade 201 is higher than the horizontal height of the cutting blade 7, so that the cutting blade 7 can be used to support the waste material and further realize the decomposition and cutting of the waste material.

[0045] Optionally, such as Figure 1 As shown, the number of cutters 7 in this application is at least two, and preferably two. The two cutters 7 are arranged in parallel, which can stably receive the falling waste material on the one hand, and form smaller waste material segments after decomposition on the other hand.

[0046] Optionally, such as Figure 1 As shown, the first guide assembly and the second guide assembly in this application also include a guide rod 504, which extends along the first direction S1.

[0047] The guide rods 504 are further designed to support and guide the waste material. The number of guide rods 504 in this application matches the number of guide plates 503, and the two are arranged opposite to each other. The guide rods 504 are designed to support and guide the waste material.

[0048] More preferably, such as Figure 1 As shown, the stamping die provided in this application also includes a baffle 8, which is disposed at the end of the cutter 7 away from the bearing module 2, and the baffle 8 is set at an angle to the cutter 7.

[0049] Since the waste material cut off needs to be decomposed by the cutter 7, in order to prevent the waste material from falling off the cutter 7 due to gravity, this application further provides a baffle 8 at the end of the cutter 7, and the baffle 8 is set at an angle to the cutter 7, so as to block and limit the waste material. Accordingly, after the cutting is completed, small-sized waste material can fall onto the waste material conveyor belt in the gap between the cutters 7, so as to realize the transfer of waste material.

[0050] Preferably, in this application, the baffle 8 is arranged perpendicular to the cutter 7, thereby enabling the blocking and limiting of waste material.

[0051] Optionally, such as Figures 1-3 As shown, the stamping die provided in this application also includes a pusher mechanism. The pusher mechanism is set on the side wall of the bearing module 2 corresponding to the positioning cutting edge 201, and the telescopic end of the pusher mechanism can contact the inner wall surface of the scrap material and extend to push the scrap material away after punching.

[0052] Because the bearing module 2 in this application forms a continuous positioning cutting edge 201, the waste material formed after punching is also a single piece of waste material. However, since the positioning cutting edge 201 is not a straight line or an arc, but a continuous irregular line and curve combination cutting edge structure, the punched waste material is prone to jamming and sticking. The waste material cannot fall smoothly, which will affect subsequent operations. Therefore, this application further sets up a pushing mechanism. After punching is completed, the pushing mechanism extends. Since the extension end of the pushing mechanism contacts the inner wall of the waste material, the extended pushing mechanism can provide an outward pushing force for the waste material, thereby separating the waste material from the product and allowing the waste material to fall smoothly onto the cutter 7, ensuring the smooth progress of the overall operation.

[0053] It should be noted that the pushing mechanism in this application can adopt a telescopic structure such as a hydraulic cylinder or a pneumatic cylinder. Taking a hydraulic cylinder as an example, when pushing is required, the piston rod of the hydraulic cylinder extends out of the cylinder body and applies a pushing force to the waste material, thereby realizing the separation of the waste material from the product. After the waste material is separated, the hydraulic cylinder retracts and waits for the next punching to be completed before pushing out the waste material.

[0054] Regardless of whether the waste is separated from the product, the pushing mechanism needs to extend to ensure that every piece of waste is separated from the product.

[0055] Preferably, such as Figure 1 As shown, the feeding mechanism in this application includes a first feeding component 3 and a second feeding component 4. The first feeding component 3 and the second feeding component 4 are spaced apart along the extension direction of the positioning blade 201, and the telescopic ends of the first feeding component 3 and the second feeding component 4 can both contact the inner wall surface of the waste material.

[0056] Since the waste material cut by this application is relatively large, by designing two pushing components, namely the first pushing component 3 and the second pushing component 4, it is possible to ensure that the waste material is smoothly released and the force is uniform, thus avoiding the problem of tilting and jamming.

[0057] More preferably, the first pushing component 3 and the second pushing component 4 in this application both include a positioning seat and a pushing component. The positioning seat is connected to the bearing module 2, the pushing component extends along the first direction S1, and the positioning end of the pushing component is connected to the positioning seat, and the telescopic end can contact the inner wall surface of the waste material.

[0058] The preferred propulsion component in this application is a cylinder, which makes the power source of the overall equipment cleaner and ensures a tidy processing space.

[0059] In addition, this utility model also provides a stamping system, including a waste conveyor belt and the above-mentioned stamping die; the waste conveyor belt is used to transfer punching waste.

[0060] The stamping system using the stamping die provided in this application can quickly remove the waste material from the product, completing the process in just one step. This saves on equipment development costs, improves operational efficiency, reduces debris generation, and enhances product quality. The cut waste material can be transported by a waste conveyor belt, forming a streamlined production line operation that requires no manual intervention, ensuring a clean working environment and further improving product quality.

[0061] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
