Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and in particular to a stamping assembly and a die having the same. Background Art

[0002] Fuel cells, especially hydrogen fuel cells, are mainly used in fuel cell powered cars, buses, trucks, fuel cell powered locomotives, fuel cell powered vehicles, aircraft, and household distributed power sources in the new energy vehicle series. Its main structure consists of a stack of multiple components with bipolar plates holding membrane electrodes. The bipolar plate is the core component of the fuel cell stack, also known as the "skeleton" of the stack. It has the functions of distributing reaction gases, supporting membrane electrodes, and collecting and guiding water generated after gas reactions. According to the different substrate materials, bipolar plates can be divided into graphite bipolar plates, metal bipolar plates, and composite bipolar plates. As for metal bipolar plates, they have the advantages of excellent mechanical strength, high conductivity, good air tightness, easy manufacturing and molding. The metal bipolar plate is composed of a cathode plate and an anode plate by welding. If the cathode plate or the anode plate is crushed in the flow channel area during the molding process, when the bipolar plate is welded and assembled into a fuel cell, it will cause the membrane electrode to deform, and in severe cases, it will even cause holes in the membrane electrode. Cause the fuel cell performance to decrease or there will be safety hazards. Therefore, there are extremely high requirements for the surface quality of the metal plate.

[0003] At present, the processing methods of metal plates are cutting, forming, and punching. Punching process may be involved in cutting and punching. However, since the plate materials used for metal plates are titanium or stainless steel, ultra-thin materials with a thickness of 0.07mm-0.12mm, and since the hole design size of the metal plate is small, the width of the hole is generally 0.8mm-1.5mm, and the minimum length is generally 3mm-6mm. Therefore, in the punching process, due to the small size and light weight of the punching waste, the waste often does not fall downwards, but jumps upwards and falls into the mold. If it is not discovered in time, it will cause batch crushing of the product, resulting in a large number of plate scraps. Summary of the invention

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] As mentioned in the background technology, in the product stamping process, the waste generated by stamping is light in weight, and the waste often does not fall downward, but jumps upward and falls into the mold, thereby damaging the product and reducing the quality of the product. Therefore, in view of the above technical problems, the present application provides a stamping assembly, wherein an airflow channel 10 is provided in the punch 1, and when the punch 1 is stamping the product 300, airflow is introduced into the airflow channel 10, and the waste 400 at the end of the punch 1 is blown downward into the blanking channel 2, and a blocking component 3 is provided in the blanking channel 2, and the blocking component 3 is movably provided. When the punch 1 gradually moves downward until the circumferential surface of the punch 1 fits with the blocking component 3, and when the punch 1 is moving upward, under the blocking effect of the blocking component 3, the waste 400 at the end of the punch 1 is blocked to prevent the waste 400 from jumping out of the mold, thereby preventing the waste 400 from damaging the product 300 and affecting the quality of the product 300.

[0024] Please refer to Figures 1 to 3 The present application provides a stamping assembly, including: a punch 1, an air flow channel 10 is arranged in the punch 1, and the air flow channel 10 extends along the length direction of the punch 1 to blow air to the end of the punch 1; a blanking channel 2 is arranged on the lower mold body 100 and is arranged opposite to the punch 1; a blocking component 3, at least partially arranged in the blanking channel 2, the position of the blocking component 3 is movably set to block or avoid the blanking channel 2, and at least part of the punch 1 is in contact with the blocking component 3 so that the punch 1 is in a discharge position.

[0025] According to the punching assembly provided by the present application, it includes a punch 1, a blanking channel 2 and a blocking component 3. An airflow channel 10 is arranged in the punch 1, and the airflow channel 10 extends along the length direction of the punch 1 to blow air to the end of the punch 1; the blanking channel 2 is arranged on the lower mold body 100 and is arranged opposite to the punch 1; the blocking component 3 is at least partially arranged in the blanking channel 2, and the position of the blocking component 3 is movably arranged to block or avoid the blanking channel 2, and at least part of the punch 1 is fitted with the blocking component 3 so that the punch 1 is in a discharge position. Such an arrangement can use the airflow channel 10 to blow air to the end of the punch 1, so that the waste 400 attached to the end of the punch 1 can be blown into the blanking channel 2. In the process of the punch 1 being gradually pressed down, until the circumferential surface of the punch 1 is fitted with the blocking component 3, the blocking component 3 blocks the waste falling into the blanking channel 2, and prevents the waste 400 from being brought back into the mold as the punch 1 rises, thereby ensuring the production quality of the product.

[0026] Specifically, Figure 1 As shown, the blanking channel 2 extends along the first direction, and the blocking component 3 is movably arranged along the second direction, and an angle is formed between the first direction and the second direction; a discharge channel 30 is arranged on the blocking component 3, and the discharge channel 30 is communicated with the blanking channel 2, and the punch 1 is arranged opposite to the discharge channel 30, and the waste at the end of the punch 1 falls into the blanking channel 2 through the discharge channel 30 through the airflow blown out of the airflow channel 10. Preferably, the cross-sectional area of ​​the passing section of the discharge channel 30 is smaller than the cross-sectional area of ​​the passing section of the blanking channel 2, and when the punch 1 fits with the blocking component 3, the punch 1 applies a force to the blocking component 3 to move the blocking component 3, so that the blocking component 3 can maintain a close fit with the punch 1, and avoid the situation where the waste jumps out due to the excessive gap between the blocking component 3 and the punch 1.

[0027] In the present application, the air flow channel 10 is connected to an external compressed air source. By blowing in compressed air, waste and dust generated during the punching process can be effectively removed to prevent them from clogging the punch or adhering to the material, affecting the subsequent punching operation. A flow regulating device is provided in the air flow channel 10 of the punch 1. The setting of the flow regulating device can adjust the flow of compressed air according to the characteristics of the punching material, optimize the punching process, and reduce the generation of waste. In the punching operation of soft materials such as plastics and rubber, this design can ensure the cleanliness of the punching process and improve the quality and appearance of the product. In practical applications, the use of the flow regulating device can also reduce energy consumption during the punching process, improve production efficiency and economic benefits. At the same time, for production lines that require high-precision punching operations, this design can ensure the stability and consistency of the punching process, and improve product quality and production efficiency.

[0028] In the specific implementation process, the blocking component 3 includes: a first blocking member 31 and a second blocking member 32, the first blocking member 31 and the second blocking member 32 are arranged oppositely and spaced apart along the second direction, the discharge channel 30 is arranged between the first blocking member 31 and the second blocking member 32, and the first blocking member 31 and the second blocking member 32 are movably arranged in a direction relatively close to or relatively far from each other. Such an arrangement can block the waste in the blanking channel 2 under the joint action of the first blocking member 31 and the second blocking member 32. In addition, the first blocking member 31 and the second blocking member 32 move separately, which can also reduce the positioning requirements between the punch 1 and the blocking component 3. Even if the positioning accuracy between the discharge channel 30 and the punch 1 is low, it can ensure that the punch 1 is smoothly inserted into the blanking channel 2.

[0029] like Figure 1 As shown, the stamping assembly also includes: a mounting cavity 4, which is arranged on the lower die body 100, a blocking component 3 is arranged in the mounting cavity 4, the mounting cavity 4 extends along the second direction and is connected to the blanking channel 2, and the blocking component 3 is movably arranged in the mounting cavity 4; an elastic component 5, which is arranged in the mounting cavity 4, and the two ends of the elastic component 5 are respectively connected to the blocking component 3 and the inner wall surface of the mounting cavity 4, and the elastic component 5 can be elastically arranged. In this way, during the process of the punch 1 and the blocking component 3 being fitted together, the punch 1 applies a force to the blocking component 3, and the blocking component 3 compresses the elastic component 5. At the same time, the elastic restoring force of the elastic component 5 is used to apply a thrust to the blocking component 3 in the direction of the punch 1, so that the blocking component 3 and the punch 1 remain in a fitted state. Preferably, the elastic component 5 is a standard wire spring with an outer diameter of 3 mm. After the spring is installed, a certain pre-tightening force should be applied to ensure that the blocking component 3 does not shake after installation.

[0030] The selection of standard wire springs makes the maintenance and replacement of mold components more convenient and reduces production costs. The 3mm outer diameter ensures sufficient elasticity while also ensuring the stability and reliability of the spring in the mold, making it suitable for punching operations of various high-strength materials, such as stainless steel and aluminum alloy. In practical applications, the 3mm outer diameter spring can not only provide stable rebound force, but also quickly reset during the punching process, reducing the waiting time for the punching operation and improving production efficiency. At the same time, the use of standard wire springs can also reduce the mold failure rate caused by spring fatigue and improve the stability and durability of the mold.

[0031] The mounting cavity 4 is a hole structure, and the aperture of the mounting cavity 4 matches the thickness of the blocking component 3. This matching design ensures the stability and reliability of the blocking component 3 during the punching process, prevents the blocking component 3 from loosening or falling off, and improves the safety of the mold. In the punching operation of high-strength materials, this design can ensure that the blocking component 3 can remain stable when subjected to a large impact force, thereby improving the durability of the mold. In practical applications, this matching design can also improve the punching accuracy, reduce the punching deviation caused by the loosening of the blocking component 3, and improve product quality. At the same time, for production lines that require high-intensity and high-frequency punching operations, this design can ensure the stability and reliability of the mold assembly, thereby improving the stability and production efficiency of the production line.

[0032] In order to facilitate the adjustment of the pressure of the elastic component 5, the stamping assembly further includes: an adjustment component 6, which is arranged in the installation cavity 4, and the adjustment component 6 is adjustably arranged along the extension direction of the installation cavity 4, and the two ends of the elastic component 5 are respectively connected to the blocking component 3 and the adjustment component 6, so as to adjust the elastic restoring force of the elastic component 5 through the adjustment component 6. When the adjustment component 6 moves toward the direction close to the blanking channel 2, the pressure on the elastic component 5 increases, so that the compression amount of the elastic component 5 increases, the elastic restoring force increases, and the thrust on the blocking component 3 is enhanced.

[0033] Preferably, in the embodiment provided in the present application, at least part of the inner wall surface of the installation cavity 4 is provided with an internal thread; the adjustment component 6 is provided with an external thread, and the adjustment component 6 is threadedly matched with the installation cavity 4. In this way, the position of the adjustment component 6 relative to the installation cavity 4 can be adjusted by screwing the adjustment component 6, which has a simple structure and is easy to operate.

[0034] Furthermore, a first limiting portion 33 is provided on the blocking component 3, and a second limiting portion 41 is provided in the installation cavity 4. The second limiting portion 41 is located at one end of the installation cavity 4 close to the blanking channel 2. At least part of the second limiting portion 41 blocks the blocking component 3 through the first limiting portion 33, so as to limit the blocking component 3 in the process of the elastic component 5 pushing the blocking component 3 to move. This arrangement can limit the moving stroke of the blocking component 3 by using the first limiting portion 33 and the second limiting portion 41 when the punch 1 has not moved into the blanking channel 2, so as to prevent the blocking component 3 from completely blocking the blanking channel 2 under the pushing action of the elastic component 5, thereby affecting the normal falling of the waste.

[0035] Preferably, the first limiting portion 33 includes a first step surface 330, and the second limiting portion 41 includes a second step surface 410, and the first step surface 330 is arranged opposite to the second step surface 410. This arrangement is easy to process, and the structure has high fatigue resistance, and can effectively stop the blocking component 3.

[0036] In the specific implementation process, the blanking channel 2 extends along the first direction, and the blocking component 3 is movably arranged along the second direction, and there is an angle between the first direction and the second direction; the blocking component 3 is provided with a discharge channel 30, and along the downward pressing direction of the punch 1, the cross-sectional area of ​​at least part of the discharge channel 30 gradually decreases. In this way, when the punch 1 is punching and moving downward at the same time, the blown-off waste and the punch 1 are guided. Preferably, the blocking component 3 is provided with a guide end face, which is an inclined surface, and the guide end face surrounds the feed port of the discharge channel 30, so that the waste 400 is merged into the blanking channel 2.

[0037] A lubricating coating is provided on the guide end surface. The use of the lubricating coating reduces the friction between the blocking component 3 and the punch 1, prolongs the service life of the blocking component 3, and reduces the maintenance cost of the mold. In the continuous punching operation, this design can ensure the smooth movement of the blocking component 3 and improve the production efficiency. In practical applications, the use of the lubricating coating can also reduce the noise during the punching process and improve the working environment. At the same time, for production lines that need to perform punching operations in high temperature or humid environments, this design can ensure the stability and reliability of the hook under different environmental conditions, and improve the adaptability and production efficiency of the production line.

[0038] In the present application, a punch hole is processed on the stripper plate of the upper die body 200, and the gap between the punch hole close to the product side and the punch is smaller than the gap between the punch and the lower die blade. This is used to ensure that when the punch vibrates abnormally during operation, the stripper plate can limit the punch to a certain extent, and the punch will not collide with the lower die blade.

[0039] The punch 1 is processed with an air flow channel 10 that runs through from top to bottom. The upper die part of the mold is processed with an air channel connected to the punch 1. The mold air channel is connected to the air source of the press through a pipeline. The press can control the on and off of the compressed air and can control the position of the slider on the press to turn the compressed air on and off.

[0040] The blocking component 3 is an inverted "L"-shaped component, and its shape is processed by wire cutting. The guide end surface and the inclined surface of the exposed part inside the punching edge are processed by optical grinding to ensure its processing accuracy.

[0041] The spring should be a standard wire spring with an outer diameter of 3mm. After the spring is installed, there should be a certain pre-tightening force to ensure that the hook will not shake after installation.

[0042] The screw plug (i.e., adjusting component 6) uses a standard M3 screw plug. Its main function is to lock the spring and adjust the size of the spring pressure. The use of the M3 standard screw plug makes it easier to lock and adjust the spring without the need for special tools, thereby improving the versatility and maintenance efficiency of the mold assembly. In daily maintenance, this design can quickly adjust the preload of the spring to meet the punching requirements of materials of different thicknesses and hardnesses. In practical applications, the use of the M3 standard screw plug can also reduce the risk of production interruptions caused by screw plug damage and improve production stability. At the same time, for production lines that require frequent material changes, this design can quickly adjust the mold assembly to meet the punching requirements of different materials, thereby improving the flexibility and production efficiency of the production line.

[0043] The installation body 500 is processed with the blocking component 3, the spring, and the installation cavity 4 of the screw plug. The lower die edge for punching is also processed. The gap between the punch and the lower die edge is selected according to the thickness of the product material. The gap value is (8%-10%) of the product material thickness and cannot be less than 0.005mm. The working height of the edge is less than the cutting depth of the punch when the mold is closed.

[0044] The lower template is a mounting plate for mounting the main body 500, and is also used to position and support the product during the production process. In one embodiment of the present application, the material of the lower template is high-strength alloy steel. The selection of high-strength alloy steel makes the lower template have better wear resistance and impact resistance, and extends the service life of the mold. In heavy industries, such as mining machinery, heavy vehicle manufacturing and other industries, this design can ensure that the mold can still maintain good performance under harsh working conditions and improve production efficiency. In practical applications, the use of high-strength alloy steel can also reduce the weight of the mold assembly and improve production flexibility. At the same time, for production lines that need to perform punching operations under high temperature and high pressure environments, this design can ensure the stability and reliability of the mold assembly, improve the adaptability and production efficiency of the production line, and reduce the risk of production interruption due to damage to the mold assembly.

[0045] Before working, the mold is in an open state, the upper and lower molds are in a separated state, and the product is placed in the positioning device on the lower mold plate. During working, the upper mold part of the mold moves downward with the upper slide of the press, and the stripper plate moves downward to first press the product on the lower mold plate. At this time, the stripper plate reaches the lower working point and stops moving. Punch 1 continues to move downward. After the punch moves downward for another 2mm-3mm with the press, punch 1 starts to work and cuts off the waste from the product 300. At this time, the press controls the air circuit switch connected to the upper mold punch airway to open, and the punch airway starts to blow air. The press continues to operate, and the punch continues to move downward with the slide on the press. After the punch cuts into the die to a depth of about 1.5 mm, the front of the punch, carrying the waste, contacts the small slope on the upper side of the end of the blocking component 3 exposed in the die blade. As the punch continues to move downward, the punch 1 squeezes the left and right blocking components 3 back until the blocking component 3 is completely retracted, and the end plane of the blocking component 3 fits with the two sides of the punch. The punch 1 completely passes through the blocking component 3 with the waste, and the cutting depth of the punch 1 exceeds the working height of the blade, and the mold reaches the lowest working point with the press. During this process, the air flow channel 10 of the punch 1 is blowing air all the time, and the waste is blown off the punch. It falls into the waste collection device.

[0046] After the press reaches the lower working point, it continues to operate. The upper slider drives the upper die of the mold to start moving upward. The punch 1 retreats upward, and the two sides of the blocking component 3 always fit the two sides of the punch until the punch is separated from the blocking component 3. Since the time from the waste falling to the separation of the punch and the blocking component 3 is very short, the waste is very small and light in weight. Due to the rapid retreat of the punch, a short pressure difference change may occur, causing the waste to be pulled upward. At this time, the punch is completely separated from the blocking component 3, and the blocking component 3 has been completely ejected. The channel size in the lower die blade is smaller than the waste size, and the waste cannot pass through and is blocked on the lower side. If the punch pores do not completely blow off the waste due to the oil film on the surface of the sheet, during the retreat of the punch 1, the end face of the blocking component 3 always fits the two sides of the punch, and the section where the waste 400 is separated from the product 300 is not completely smooth, even if the waste is not completely separated from the punch, during the retreat of the punch, the blocking component 3 will scrape the waste off the punch, so that the waste is blocked on the lower side of the blocking component 3.

[0047] The press continues to operate, the punch 1 is separated from the product, the press controls the air circuit switch connected to the upper die punch airway to close, and the punch air circuit stops blowing until the press returns to the upper working point and completes the entire punching action, at which time the product can be taken out.

[0048] The punching assembly of the present application has the function of preventing waste from jumping out, and can meet the needs of large-scale automated production. The structure is simple in design, easy to maintain, efficient in use, and meets the characteristics of automated production. The method is suitable for punching small holes in various thin plates, which can effectively reduce the pressure damage of the product and ensure the quality requirements of the product.

[0049] The cutting depth of the punch matches the lower die blade. Matching cutting depths can ensure the consistency and accuracy of punching, reduce scrap rate, and improve production efficiency. In the construction industry, this design can ensure that the punching operations of materials such as steel bars and steel plates meet standard requirements and improve the safety of building structures. In practical applications, this matching design can also reduce the wear of the punch, extend the service life of the die, and reduce maintenance costs. At the same time, for materials that need to be punched multiple times, this design can ensure the accuracy and consistency of the punching position, improve the product qualification rate and production efficiency.

[0050] The present application also provides a mold, including a stamping assembly and a mold body, wherein the stamping assembly is arranged in the mold body, and the stamping assembly is the stamping assembly of the above embodiment.

[0051] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0052] According to the punching assembly provided by the present application, it includes a punch 1, a blanking channel 2 and a blocking component 3. An airflow channel 10 is arranged in the punch 1, and the airflow channel 10 extends along the length direction of the punch 1 to blow air to the end of the punch 1; the blanking channel 2 is arranged on the lower mold body 100 and is arranged opposite to the punch 1; the blocking component 3 is at least partially arranged in the blanking channel 2, and the position of the blocking component 3 is movably arranged to block or avoid the blanking channel 2, and at least part of the punch 1 is fitted with the blocking component 3 so that the punch 1 is in a discharge position. Such an arrangement can use the airflow channel 10 to blow air to the end of the punch 1, so that the waste 400 attached to the end of the punch 1 can be blown into the blanking channel 2. In the process of the punch 1 being gradually pressed down, until the circumferential surface of the punch 1 is fitted with the blocking component 3, the blocking component 3 blocks the waste falling into the blanking channel 2, and prevents the waste 400 from being brought back into the mold as the punch 1 rises, thereby ensuring the production quality of the product.
