[0002] As an important component of modern automobile exhaust systems, the automobile three-way catalytic converter plays an indispensable role. As a key component of exhaust gas purification, the three-way catalytic converter plays a vital role in protecting the environment and reducing air pollution with its unique working principle and excellent purification efficiency. In addition, the three-way catalytic converter also has a muffler function, which further reflects its important value in automobile exhaust systems.

[0003] However, at the process level, traditional processing technology generally relies on three intermittent processes of punching, punching special-shaped holes and pressing, which not only leads to high mold investment costs, but also reduces production efficiency due to the need for frequent repeated positioning.

[0023] 1. In this application, we integrated the equipment required for the three traditional intermittent processes of punching, punching special-shaped holes and pressing into a single device. After the equipment improvement, the time interval between the three processes of punching round holes, punching elliptical holes and pressing was significantly shortened. Specifically, the equipment first punches round holes, then punches elliptical holes, and finally completes the pressing work in six steps. During the entire process, there is no need to completely disassemble the mold of the equipment (only by quickly replacing the upper mold), and all punching and pressing processes are efficiently completed in an eight-step process. Compared with the traditional multi-process design, the cost investment of this mold development has been reduced by about two-thirds, effectively reducing the frequent auxiliary time of mold installation and demolding, significantly improving production efficiency, and further ensuring the quality of the three-way catalytic converter after processing.

The stripping screw precisely passes through the upper die base plate, the upper die pad and the punch fixing plate, and is finally firmly locked on the press plate, thereby realizing the precise limit of the press plate stroke. On the press plate, multiple springs are evenly distributed in an orderly manner, and when the upper die assembly moves downward, the springs will undergo a compression process. After the upper die assembly and the lower die assembly are closed, when the upper die assembly starts to return, the spring exerts its elastic force to push the press plate, so that the material plate can be smoothly separated from the punch component and the die component, thereby realizing an effective stripping action. Throughout the process, the press plate always fits closely to the surface of the material plate and the die component to ensure the integrity of the parts and prevent them from deformation. After the stripping is completed, the press plate is quickly reset to prepare for the next stamping operation. In order to ensure the stable operation and precise control of the entire system, the manufacture and installation of all components follow strict process standards and quality control procedures.

[0025] 3. In the present application, in the structure of the die assembly, one end is firmly mounted on the die fixing plate, which causes the other end to present a cantilever structural characteristic. When performing operations such as punching or profiling, the unsupported end will be subjected to the force, and it will often bend and deform downward. To solve this problem, we specially configured a pneumatic slider assembly at the front of the lower die. The assembly consists of multiple components such as a cylinder, a cylinder fixing seat, a slide seat, a slider and a support block, and realizes its function through the synergy with the start switch. Before the operation starts, we activate the start switch to withdraw the slider, thereby forming an effective support at the bottom of the die; and before taking the part, the start switch is operated again to withdraw the slider, thereby smoothly realizing the process of taking the part. The entire operation process ensures the stability of the die assembly and the convenience of taking the part. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Example:

[0046] A novel stamping die for processing a catalyst housing comprises a workbench, an upper die assembly 10 connected to the workbench, a lower die assembly 20 arranged opposite to the upper die assembly 10, and a material plate 90, wherein the upper die assembly 10 comprises an upper die base plate 110, an upper die pad 120 is arranged on the bottom surface of the upper die base plate 110, a punch fixing plate 130 is arranged on the bottom surface of the upper die pad 120, a material pressing component 150 for stamping is arranged on the bottom surface of the punch fixing plate 130, and a punch component 160 for stamping forming is arranged inside the material pressing component 150;

[0047] The lower die assembly 20 comprises a lower die base plate 210, a pair of raised seats 220 are symmetrically arranged on the top surface of the lower die base plate 210, wherein a first circumferential positioning device 240 is arranged on the top surface of at least one of the raised seats 220, a die fixing component 230 is arranged along the vertical direction of the two raised seats 220, a die component 80 is arranged inside the die fixing component 230, the material plate 90 is arranged on the outer wall of the die component 80, and a second circumferential positioning device and a third circumferential positioning device are arranged inside the die component 80;

[0048] The top surface of the lower die base plate 210 is also provided with a pneumatic slider component 30 for supporting the female die component 80 and a start switch 40 , wherein the start switch 40 is used to control the pneumatic slider component 30 .

[0049] To explain, we have integrated the equipment required for the three traditional intermittent processes of punching, punching special-shaped holes and pressing into a single device. After the equipment improvement, the time interval between the three processes of punching round holes, punching elliptical holes and pressing has been significantly shortened. Specifically, the equipment first punches round holes, then punches elliptical holes, and finally completes the pressing work in six steps. During the entire process, there is no need to completely disassemble the mold of the equipment (only by quickly replacing the upper mold), and all punching and pressing processes are efficiently completed in an eight-step process. Compared with the traditional multi-process design, the cost investment of this mold development has been reduced by about two-thirds, effectively reducing the frequent auxiliary time of mold installation and demolding, significantly improving production efficiency, and further ensuring the quality of the three-way catalytic converter after processing.

[0050] Specifically, the first circumferential positioning device 240 provided on the top surface of the raising seat 220, and the second circumferential positioning device and the third circumferential positioning device provided inside the die part 80 can cooperate with the punch part 160 to fix the three processes of punching circular holes, punching elliptical holes and pressing, and then cooperate with the die part 80 to ensure that the processing of circular holes, elliptical holes and teardrop-shaped surfaces is completed when processing the material plate 90, ensuring that the best processing quality can meet the actual requirements.

[0051] It is worth mentioning that the punch fixing plate 130 of the upper die assembly 10 can be made of high-strength alloy material to ensure that the punch fixing plate 130 can maintain a stable shape and size during long-term, high-intensity stamping, thereby ensuring the durability of the stamping accuracy. The punch component 160 inside the pressing component 150 is also recommended to be made of cemented carbide material, which has excellent wear resistance and impact resistance, and can maintain a sharp cutting edge during high-frequency stamping, thereby ensuring the accuracy and surface quality of the stamped parts. The first circumferential positioning device 240, the second circumferential positioning device and the third circumferential positioning device ensure that during the stamping process, the material plate 90 can be accurately positioned and fixed on the lower die base plate 210, thereby avoiding misalignment and deformation of the stamped parts. Among them, a pneumatic slider 340 assembly is also configured at the front of the lower die to support the unsupported end of the die assembly to avoid downward bending deformation.

[0052] Combined with the accompanying drawings Figure 1-Figure 8 As shown, the upper mold assembly 10 also includes an upper foot plate 170 and a first limiting column 140. At least three upper foot plates 170 are provided and fixed in the same row on the top surface of the upper mold base plate 110. The upper mold base plate 110 is connected to the workbench through the upper foot plates 170. The first limiting column 140 and the second limiting column 270 provided on the top surface of the raising seat 220 conflict with each other to limit the stamping height.

[0053] It is explained that the upper foot plate 170 is an important component connecting the upper die base plate 110 and the workbench. By setting at least three upper foot plates 170 fixed in the same row, a stable connection between the upper die base plate 110 and the workbench is ensured, and the necessary support is also provided for the entire stamping process. This design not only enhances the stability of the structure, but also improves the stamping accuracy and efficiency. The first limiting column 140 plays an indispensable role in limiting the stamping height and protecting equipment and products. When working, the upper die base plate 110 will move downward, contact the lower die assembly 20 and complete the stamping process. In this process, the first limiting column 140 will conflict with the second limiting column 270 on the top surface of the pad 220, thereby limiting the downward distance of the upper die base plate 110, that is, the height of the stamping.

[0054] Specifically, by limiting the stamping height, we can ensure that no excessive pressure is generated during the stamping process, thereby avoiding problems such as equipment damage and product deformation. Secondly, this design also improves the accuracy and stability of stamping, so that each stamping can achieve the preset effect. Finally, when the equipment fails or is abnormal, the interference between the first limit column 140 and the second limit column 270 can also play a protective role, preventing further damage to the equipment or safety accidents.

[0055] Combined with the accompanying drawings Figure 1-Figure 9 As shown, the pressing component 150 includes a pressing plate 1510, a plurality of stripping screws 1520 and a plurality of springs 1530, one end of the stripping screw 1520 is screwed into the upper die base plate 110, and the other end of the stripping screw 1520 passes through the upper die pad 120 and the punch fixing plate 130 and is connected to the pressing plate 1510, one end of the spring 1530 is connected to the upper die pad 120, and the other end of the spring 1530 passes through the punch fixing plate 130 and is connected to the pressing plate 1510.

[0056] It is explained that the stripping screw 1520 precisely passes through the upper die base plate 110, the upper die pad 120 and the punch fixing plate 130, and is finally firmly locked on the press plate 1510, thereby realizing the precise limit of the stroke of the press plate 1510. On the press plate 1510, multiple springs 1530 are evenly distributed in an orderly manner. When the upper die assembly 10 moves downward, the spring 1530 will undergo a compression process. After the upper die assembly 10 and the lower die assembly 20 are closed, when the upper die assembly 10 starts to return, the spring 1530 exerts elastic force to push the press plate 1510, so that the material plate 90 is smoothly separated from the punch component 160 and the die component 80, thereby realizing an effective stripping action. During the whole process, the press plate 1510 always closely fits the surface of the material plate 90 and the die component 80 to ensure the integrity of the parts and prevent them from deformation. After the stripping is completed, the press plate 1510 is quickly reset to prepare for the next stamping operation. To ensure stable operation and precise control of the entire system, the manufacture and installation of all components follow strict process standards and quality control processes.

[0057] Combined with the accompanying drawings Figure 1-Figure 11 As shown, the upper die assembly 10 is provided with a first mounting hole, a second mounting hole and a third mounting hole, respectively, and the first mounting hole, the second mounting hole and the third mounting hole all penetrate the upper die base plate 110, the upper die pad 120, the punch fixing plate 130 and the press plate 1510;

[0058] The punch component 160 includes a first punch 1610, a second punch 1620, a third punch 1630, a first push rod 1640, a second push rod 1650 and a third push rod 1660. The first punch 1610, the second punch 1620 and the third punch 1630 are respectively located at the lower part of the first mounting hole, the second mounting hole and the third mounting hole, and the first push rod 1640, the second push rod 1650 and the third push rod 1660 are respectively arranged at the upper part of the first mounting hole, the second mounting hole and the third mounting hole, and are screwed to the upper die base plate 110.

[0059] It is explained that the equipment required for the three intermittent processes of punching, punching special-shaped holes and pressing are integrated into a single device. After the equipment improvement, the time intervals between the three processes of punching round holes, punching elliptical holes and pressing are significantly shortened. Specifically, the first punch 1610, the second punch 1620 and the third punch 1630 are fixed on the punch fixing plate 130, and the punch fixing plate 130 is connected to the upper die pad 120 by screws and positioning pins. The first punch 1610, the second punch 1620 and the third punch 1630 are respectively provided with a first push rod 1640, a second push rod 1650 and a third push rod 1660 at their upper ends. The push rods 1660 are all locked on the upper die base plate 110 by screw plugs, and their positioning upper surfaces are flush with the upper surface of the upper die base plate 110. The upper surface of the screw plugs is covered by the upper foot plate 170 to ensure that the forces of the first punch 1610, the second punch 1620 and the third punch 1630 are all transmitted to the lower surface of the upper foot plate 170 during operation, preventing the screw plugs from being displaced in the upper die base plate 110 due to the force, thereby causing the stroke of the punch component 160 to change.

[0060] Specifically, the structure is designed as a set of efficient and fast disassembly devices, which is intended to quickly separate the upper die assembly 10 from the equipment workbench. The specific operation process is as follows: First, loosen and remove the middle upper foot plate 170, and then remove the screw plug. The top of the punch component 160 is equipped with a standard M8 thread to adapt to the pin puller, so as to easily remove or replace the first punch 1610, the second punch 1620 or the third punch 1630, and the corresponding first ejector rod 1640, the second ejector rod 1650 or the third ejector rod 1660. After completing the replacement of the punch and the ejector rod, re-install the required punch and ejector rod in the established order, lock the screw plug, and reinstall the middle upper foot plate 170. Finally, ensure that the upper die base plate 110 is firmly locked on the workbench of the equipment to achieve the purpose of quick replacement. The whole process is easy to operate, efficient and fast, and significantly improves production efficiency.

[0061] Combined with the accompanying drawings Figure 1-Figure 11 As shown, the die fixing component 230 includes a die fixing seat 2310, a die fixing plate 2320 and an inner guide sleeve 2330 symmetrically opened on the top surface of the die fixing seat 2310, the die fixing plate 2320 is screwed on the die fixing seat 2310, and the die component 80 passes through the die fixing seat 2310 and is detachably connected to the die fixing plate 2320; the pressing component 150 also includes an inner guide column 1540, which is fixed to the bottom surface of the upper die pad 120 and is connected with the inner guide sleeve 2330.

[0062] It is explained that in the construction of the stamping die, the precise matching of the die fixing part 230 and the material pressing part 150 is crucial to ensure the quality of the stamping parts and the service life of the die. The die fixing seat 2310 is recommended to be made of high-strength, wear-resistant alloy steel material to ensure that it remains stable when subjected to huge stamping pressure. At the same time, the symmetrical inner guide sleeve 2330 opened on its top surface not only provides precise guidance for the die part 80, but also reduces the friction and wear of the die part 80 during the stamping process through its internal lubrication structure. Among them, the die part 80 is screwed to the die fixing plate 2320, which realizes fast and convenient replacement and maintenance.

[0063] Combined with the accompanying drawings Figure 1-Figure 11 As shown, the first circumferential positioning device 240 includes a positioning seat 2410, a positioning block 2420 and a latch 2430. The positioning seat 2410 is arranged on the top surface of the raising seat 220, the positioning block 2420 is arranged inside the positioning seat 2410 and abuts against the outer wall of the material plate 90, and the latch 2430 is arranged on the end surface of the die fixing seat 2310 facing the pneumatic slider component 30 and abuts against the outer wall of the material plate 90.

[0064] It is explained that the positioning seat 2410 is the basis of the entire positioning device, and it is firmly installed on the top surface of the pad seat 220 to ensure that it will not be displaced when subjected to pressure from the material plate 90 or other components. The positioning block 2420 is installed inside the positioning seat 2410 and is in close contact with the outer wall of the material plate 90. The positioning block 2420 is usually made of wear-resistant and high-strength materials to ensure that its shape and accuracy can be maintained after long-term use. The design of the positioning block 2420 allows it to be fine-tuned according to the size and shape of the material plate 90, thereby ensuring the precise position of the material plate 90 during the processing, and the latch 2430 is set on the end face of the die fixing seat 2310 facing the pneumatic slider component 30, and is also in close contact with the outer wall of the material plate 90. The function of the latch 2430 is to further enhance the stability of the material plate 90 and prevent displacement due to vibration or impact during the processing. The insertion and removal of the latch 2430 can be achieved through simple mechanical operations, which is convenient and quick.

[0065] Specifically, during the processing, the positioning block 2420 contacts the outer wall of the material plate 90 to initially position the material plate 90 in the correct position. Then, the latch 2430 further fixes the position of the material plate 90. In this way, the positioning device ensures the stability and accuracy of the material plate 90 during the processing, thereby improving the quality of the product and the processing efficiency.

[0066] Combined with the accompanying drawings Figure 1-Figure 11As shown, the pneumatic slider component 30 includes a cylinder fixing seat 310 and a slide seat 330, wherein a cylinder 320 is fixed inside the cylinder fixing seat 310, and the cylinder 320 is connected to the starting switch 40; a slider 340 is arranged in the slideway opened inside the slide seat 330, and a support block 350 is arranged on the top surface of the slider 340, and the top surface of the support block 350 is in contact with the bottom surface of the die component 80.

[0067] It is explained that the cylinder fixing seat 310 is the basic part of the pneumatic slider component 30, and its main function is to provide a stable installation platform for the cylinder 320, ensuring that the cylinder 320 can be firmly fixed therein and will not shake or deviate during operation. In addition, the cylinder fixing seat 310 also has a certain load-bearing capacity, which can withstand various forces generated by the cylinder 320 during operation, thereby ensuring the stability and safety of the mold system, wherein the cylinder 320, as the power source of the pneumatic slider component 30, realizes precise control of the movement of the slider 340 through connection with the start switch 40. When the start switch 40 is triggered, the piston rod inside the cylinder 320 will quickly extend or retract, thereby pushing the slider 340 to slide in the slideway in the slideway seat 330. This control method has the characteristics of fast response speed and high control accuracy, and can meet the requirements of the mold system for precise control of the position of the slider 340.

[0068] Specifically, the slideway opened inside the slideway seat 330 is the place where the slider 340 slides. The design of the slideway fully considers the movement characteristics and force conditions of the slider 340, and can be made of wear-resistant and corrosion-resistant materials to ensure that the slider 340 can still maintain stable movement performance during long-term use. In addition, the slideway also has a certain guiding function, which can ensure that the slider 340 always remains on the correct track during the sliding process, and a support block 350 is provided on its top surface. The main function of the support block 350 is to support the die component 80 and ensure that the position of the die component 80 in the mold system is stable. During the sliding process of the slider 340, the support block 350 will generate a resistance force with the bottom surface of the die component 80, and this resistance force will make the die component 80 fit tightly on the slider 340, thereby avoiding the misalignment or shaking phenomenon that may occur during the mold closing process.

[0069] Combined with the accompanying drawings Figure 1-Figure 11As shown, the female die component 80 includes a female die block 810 and a female die insert 850. The female die block 810 is screwed onto the female die fixing plate 2320. Inside the female die block 810, there are also a first groove 820, a second groove 830, and a third groove 840. The second circumferential positioning device 250 is installed inside the first groove 820, the third circumferential positioning device 260 is installed inside the second groove 830, and the female die insert 850 is installed inside the third groove 840. The second circumferential positioning device 250, the third circumferential positioning device 260, and the female die insert 850 all abut against the stock plate 90.

[0070] Explanation is made that the female die block 810, as the main body of the female die component 80, is firmly fixed on the female die fixing plate 2320 by screwing, ensuring no displacement or deformation during the use of the die. This design not only guarantees the stability of the die but also makes the replacement and maintenance of the female die block 810 more convenient. The first groove 820, the second groove 830, and the third groove 840 opened inside the female die block 810 respectively carry different functional components. The second circumferential positioning device 250 is installed inside the first groove 820, and its main function is to ensure the precise positioning of the stock plate 90 during stamping and prevent production defects caused by position deviation. The third circumferential positioning device 260 is installed inside the second groove 830, and its function is similar to that of the second circumferential positioning device 250, but it mainly plays an auxiliary positioning role. In some production scenarios that require higher positioning accuracy, the addition of the third circumferential positioning device 260 can further improve the positioning accuracy of the die, thereby improving the product quality. The female die insert 850 is installed inside the third groove 840, and it directly contacts the stock plate 90 and performs stamping processing.

[0071] Combined with the attached drawings of the specification Figure 1-Figure 11 As shown, the guiding component 60 includes a guiding seat 610 and guiding columns 620. There are at least four guiding seats 610 and guiding columns 620. The guiding seats 610 are arranged in two rows symmetrically on the bottom surface of the upper die base plate 110, and the guiding columns 620 are arranged in two rows on the top surface of the lower die base plate 210. The guiding seats 610 and the guiding columns 620 are cooperatively connected to each other.

[0072] It is explained that in the above structure, the design and arrangement of the guide component 60 not only ensures the stable operation of the mold, but also improves the precision and life of the mold. The mutual cooperation and connection between the guide seat 610 and the guide column 620 ensures the precise alignment of the mold during the closing and opening process, and effectively prevents the mold from offsetting or shaking during high-speed movement. Among them, the guide seat 610 is divided into two rows and symmetrically arranged on the bottom surface of the upper mold base plate 110. Such a layout design makes the force between the upper and lower mold base plates 210 more uniform when the mold is closed, further improving the stability and service life of the mold. At the same time, the symmetrical layout of the guide seat 610 also makes the installation and debugging of the mold more convenient and quick, and the guide column 620 is divided into two rows and arranged on the top surface of the lower mold base plate 210, corresponding to the guide seat 610 one by one, forming a stable guide system. The material and processing accuracy of the guide column 620 are strictly screened and controlled to ensure that it can withstand the impact and wear of the mold during high-speed movement and maintain long-term stability and accuracy.

[0073] Combined with the accompanying drawings Figure 1-Figure 11 As shown, the top surface of the lower die base plate 210 is also provided with a fork transport component 50 and a horizontal positioning component 70, and at least four fork transport components 50 are provided and are respectively installed at the four corners of the top surface of the lower die base plate 210; the horizontal positioning component 70 includes two longitudinal keys and one transverse key, and the longitudinal keys and the transverse key are used to realize the positioning of the cushion seat 220 and the die fixing component 230.

[0074] It is explained that the forklift component 50 is installed at the four corners of the top surface of the lower die base plate 210 to ensure that the mold can be moved smoothly and accurately during the transportation of the mold, whether it is hoisting or forklift operation, thereby avoiding damage to the mold during transportation and improving work efficiency. As for the horizontal positioning component 70, it is composed of two longitudinal keys and one transverse key. These three key positions form a stable positioning structure on the lower die base plate 210. When the pad 220 and the die fixing component 230 need to be installed or removed, these three key positions can ensure that they are accurately placed in the predetermined position, thereby ensuring the overall accuracy and stability of the mold.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
