[0043] Example:

[0044] An air intake cone clamping and flanging die comprises a press, an upper die base 10 and a lower die base 20, wherein the top surface of the upper die base 10 is connected to the press, and the lower die base 20 is connected to the bottom surface of the upper die base 10;

[0045] The upper die base 10 comprises an upper die end plate 1010 and an upper die pad 1020, wherein the upper die pad 1020 is arranged on the bottom surface of the upper die end plate 1010, a punch pad 1030 is arranged on the bottom surface of the upper die pad 1020, a pressing plate 1040 is arranged on the bottom surface of the punch pad 1030, and a punch component 1050 is arranged on the bottom surface of the pressing plate 1040;

[0046] The lower die base 20 includes a lower die end plate 2010 and a fixing component, wherein the fixing component is arranged on the top surface of the lower die end plate 2010, and a mounting hole is also provided on the top surface of the fixing component, a concave die 2070 is arranged inside the mounting hole, and a material ejection core 2080 is arranged inside the concave die 2070;

[0047] The bottom surface of the lower die base 20 is also provided with a cushion block 30 and a supporting foot 40 for supporting function.

[0048] It is explained that a new type of automobile stamping and flanging die can be formed by the combined assembly of a press, an upper die base 10 and a lower die base 20. During operation, the lower die top core 2080 is in a lifted state when the die is open, and the upper die pressing plate 1040 is in an active state when the die is open. The unflagged product is placed on the top core 2080 and positioned in place using the molding surface. Subsequently, the upper die base 10 is driven downward by the press to complete the flanging of the die. During the flanging process of the die, when the upper die base 10 and the lower die base 20 are in contact, the pressing plate 1040 in the upper die base 10 will always press the unflanged surface of the product, keeping it in a pressed state during the working process until the flanging is completed. The above method can solve the problem of wrinkles on the flanging surface of the product, thereby ensuring the product quality. In addition, the die has a reasonable structure, compact content, and low cost, which is more conducive to subsequent development.

[0049] Combined with the accompanying drawings Figure 1-Figure 3 The upper die base 10 and the lower die base 20 are also respectively provided with a first limiting component and a second limiting component. There are at least two of the first limiting component and the second limiting component, which are symmetrically arranged on the end faces of the upper die end plate 1010 and the lower die end plate 2010, and the second limiting component is detachably connected to the first limiting component.

[0050] It is explained that during the flanging operation, the lower die base 20 maintains a stationary state, while the upper die base 10 performs a downward stamping operation under the drive of the press. In order to ensure that the upper die base 10 can be accurately aligned with the lower die base 20 during the stamping process, a first limiting component and a second limiting component are set between the upper die base 10 and the lower die base 20. The function of these two limiting components is that when the press drives the upper die base 10 to stamp downward, its motion trajectory can be accurately limited, thereby ensuring the precise alignment between the upper die base 10 and the lower die base 20 to successfully complete the stamping work. In the process of completing the flanging work, the first limiting component and the second limiting component play a vital role. They not only ensure the accurate alignment between the upper die base 10 and the lower die base 20, but also improve the stability and reliability of the entire stamping process by limiting the motion trajectory of the upper die base 10. This design not only improves the efficiency of the flanging work, but also reduces the scrap rate that may be caused by inaccurate positioning.

[0051] Combined with the accompanying drawings Figure 6A plurality of first elastic components 1080 are also arranged between the upper die end plate 1010 and the pressure plate 1040, and the plurality of first elastic components 1080 are distributed outside the punch pad 1030, the first elastic component 1080 includes a spring 1081 and a guide pin 1082, one end of the spring 1081 is connected to the upper die end plate 1010, and the other end of the spring 1081 is connected to the pressure plate 1040, one end of the guide pin 1082 is arranged inside the spring 1081, and the other end of the guide pin 1082 is connected to the pressure plate 1040.

[0052] It is explained that the spring 1081 in the first elastic component 1080 mainly plays the role of buffering and shock absorption. When the pressing plate 1040 applies pressure to the upper mold end plate 1010, the spring 1081 can effectively absorb and disperse this pressure to prevent damage to the mold or workpiece due to the instantaneous strong impact. At the same time, during the working process of the mold, due to the influence of various factors, such as uneven hardness of the material, machining accuracy error, etc., the contact between the pressing plate 1040 and the upper mold end plate 1010 may cause slight vibration. The existence of the spring 1081 can absorb these vibrations, reduce noise, and improve the stability and service life of the mold. The guide pin 1082 is an auxiliary component of the spring 1081, one end of which is set inside the spring 1081 and the other end is connected to the pressing plate 1040. During the working process of the mold, the guide pin 1082 plays the role of guiding and positioning, ensuring that the pressing plate 1040 moves accurately in the vertical direction to prevent machining errors caused by offset or tilt.

[0053] Combined with the accompanying drawings Figure 4-6 The punch component 1050 includes an upper punch 1051 and a guide block 1052. The upper punch 1051 is fixed to the bottom surface of the pressing plate 1040 by screws. A through hole is opened on the upper punch 1051. The bottom of the guide block 1052 passes through the through hole and is fixed to the bottom surface of the pressing plate 1040 by screws.

[0054] It is explained that the upper punch 1051 is the main component of the punch part 1050, which is responsible for forming the shape of the workpiece during the stamping process. It is fixed to the bottom surface of the pressure plate 1040 by screws. The upper punch 1051 can stably withstand the huge pressure generated during the stamping process to ensure that the shape of the workpiece is accurate and consistent. The existence of the guide block 1052 plays a guiding and supporting role. Fixed to the bottom surface of the pressure plate 1040 by screws, the guide block 1052 and the upper punch 1051 together constitute a stable stamping structure. During the stamping process, the guide block 1052 can ensure the precise movement trajectory of the upper punch 1051 to prevent the workpiece shape from being poor due to offset or shaking.

[0055] Combined with the accompanying drawings Figure 7 and Figure 8 The fixing parts include a reinforcing pad 2020, a die 2070 pad 2030 and a die 2070 fixing frame 2040. The reinforcing pad 2020 is arranged on the top surface of the lower die end plate 2010, the die 2070 pad 2030 is arranged on the top surface of the reinforcing pad 2020, and the die 2070 fixing frame 2040 is arranged on the top surface of the die 2070 pad 2030. The mounting hole is opened through the reinforcing pad 2020, the die 2070 pad 2030 and the die 2070 fixing frame 2040. The die 2070 is arranged on the top of the mounting hole and is fixedly connected to the die 2070 fixing frame 2040.

[0056] It is explained that the setting of the fixing parts is to ensure the stability and accuracy of the die 2070. The reinforcing pad 2020, as the bottom support, not only provides a stable foundation, but also can disperse and bear the pressure from the die 2070, effectively preventing the lower die end plate 2010 from deformation. The die 2070 pad 2030 strengthens the connection between the die 2070 and the reinforcing pad 2020, further ensuring the stability of the die 2070. The design of the die 2070 fixing frame 2040 provides a precise positioning and fixing environment for the die 2070, ensuring the stability and accuracy of the die 2070 during the working process, wherein the opening of the mounting hole allows the die 2070 to be easily installed and disassembled. At the same time, the die 2070 is fixedly connected to the die 2070 fixing frame 2040 through the mounting hole, ensuring that the die 2070 will not be displaced during the working process, thereby ensuring the quality and accuracy of the product.

[0057] Combined with the accompanying drawings Figure 1-Figure 9 A second elastic component 2090 is also arranged between the bottom of the top material core 2080 and the lower mold end plate 2010, and the second elastic component 2090 includes a plurality of nitrogen springs 2091, a plurality of limit screws 2092 and a plurality of inner guide pillars 2093. One ends of the nitrogen springs 2091, the limit screws 2092 and the inner guide pillars 2093 are all installed on the top surface of the lower mold end plate 2010, and the other ends of the nitrogen springs 2091, the limit screws 2092 and the inner guide pillars 2093 are all connected to the bottom surface of the top material core 2080.

[0058] It is explained that during the working process of the mold, the ejector core 2080 not only needs to withstand the huge pressure from the workpiece, but also needs to ensure that it can smoothly and accurately complete the action during the ejection process. Therefore, the setting of the second elastic component 2090 can ensure the stability and reliability of the ejector core 2080. The nitrogen spring 2091, with its unique elastic characteristics, can provide uniform rebound force during the ejection process, effectively preventing the problem of uneven ejection caused by uneven weight of the workpiece or mold deviation, and the limit screw 2092 plays a role in limiting the stroke of the ejector core 2080. During the ejection process, the limit screw 2092 can ensure that the ejector core 2080 will not interfere with other parts of the mold due to excessive ejection, thereby protecting the mold from damage. At the same time, the limit screw 2092 can also provide stable support when the ejector core 2080 is reset, ensuring that it returns to its original position accurately, and the inner guide column 2093 is mainly responsible for guiding the lifting and lowering movement of the ejector core 2080 to ensure its stability during the working process. Through the precise guidance of the inner guide pin 2093, the ejection core 2080 can move smoothly along a predetermined track, avoiding poor ejection due to offset or tilt.

[0059] Combined with the accompanying drawings Figure 1-Figure 9 The first limiting component and the second limiting component are fixedly connected by screws, the first limiting component includes a guide sleeve 1060 and a first limiting column 1070, the second limiting component includes a second limiting column 2050 and a guide column 2060, the guide column 2060 is inserted into the guide sleeve 1060 and fixed by screws, and the bottom surface of the first limiting column 1070 is in conflict with the top surface of the second limiting column 2050.

[0060] It is explained that the fixed connection mode of the first limiting component and the second limiting component ensures the stability and reliability of the structure. Screws, as commonly used connecting parts, not only realize the fixation between components, but also ensure the firmness and durability of the connection.

[0061] Specifically, the plug-in structure of the guide sleeve 1060 and the guide post 2060 not only provides a guiding effect for the components, but also enhances the stability of the overall structure. Through the fixation of the screws, the connection between the guide post 2060 and the guide sleeve 1060 is tighter and less likely to loosen, thereby ensuring the relative position stability between the components. In addition, the interference design between the bottom surface of the first limiting post 1070 and the top surface of the second limiting post 2050 further enhances the limiting effect of the structure. This interference design enables the two limiting components to generate a stable supporting force when interacting with each other, thereby limiting the movement of the components in a specific direction. This limiting method is accurate and effective, which helps to ensure the normal operation of the entire stamping process.

[0062] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. 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.
