Description

Technical Field

[0001] The invention relates to the technical field of cold stamping dies for automobile outer covering parts, and in particular to an uncoiling and blanking die, method, terminal equipment and storage medium. Background Art

[0002] The uncoiling and blanking process of left and right rear door inner panels without window frames is used to efficiently and accurately prepare the exterior panels of automobiles, providing sheets that meet the design requirements for subsequent drawing and forming. This process ensures the forming performance and quality of the parts in the subsequent processing through specific cutting and punching operations. Figure 1 , Figure 1 The figure is a typical process flow diagram of blanking process of rear side door inner panel without window frame in the prior art. In the prior art, the blanking process of rear side door inner panel without window frame is usually carried out in two steps. The first step is process corner cutting and process punching. The corner cutting is added in the C-pillar wheel housing area, the B-pillar bottom corner area and the internal waste area of ​​the part to optimize the forming performance of the sheet material and avoid cracks or deformation during the drawing process. Then, punching is added in specific areas to facilitate subsequent processing and assembly. The second step is cutting and separation. After completing the corner cutting and punching operations, cutting and separation are performed to finally obtain the sheet material that meets the design requirements.

[0003] However, the large difference in cutting length between different projects leads to large differences in mold size, which leads to increased production costs and increases the complexity of mold design and manufacturing. For example, in the E260 and EQ100 projects, although the step difference is 122mm, the cutting length difference is 206mm, and the length dimension of the mold differs by 610mm. In addition, each set of mold structure drawings is customized according to specific parts during unwinding and blanking, and the size and weight of the mold structure drawings designed by different manufacturers vary greatly, and no standardized process has been formed. Once the casting is almost impossible to change, it is not compatible and universal. When the model is discontinued, the mold parts cannot be reused and can only be scrapped, resulting in a large waste of resources. The unwinding and blanking process of the left and right rear side door inner panels without window frames plays an important role in automobile manufacturing, but in actual applications, there are two major technical defects: the cutting length is not standardized and the mold structure is not standardized. These problems not only increase production costs, but also reduce production flexibility and resource utilization efficiency. Summary of the invention

[0004] The present invention aims to provide a coil unwinding and blanking die, method, terminal equipment and storage medium to solve the above-mentioned technical problems and improve the production flexibility and resource utilization efficiency of the coil unwinding and blanking process.

[0005] In order to solve the above technical problems, the present invention provides a method comprising: an upper die base and a lower die base that cooperate with each other, a frame support mechanism, an inclined wedge support mechanism and a trimming and punching module;

[0006] The upper die base and the lower die base are synchronously divided into a plurality of universal installation areas according to the universal vehicle structure; wherein the upper die base is slidably connected with the lower die base through guide mechanisms at four corners;

[0007] The frame supporting mechanism is disposed on the surface of the lower die seat along the contour of the lower die seat; wherein the frame supporting mechanism pushes the sheet material forward based on the roller arrangement;

[0008] The inclined wedge supporting mechanism is arranged at a preset position of the lower die seat, and the inclined wedge supporting mechanism provides support for the sheet material;

[0009] The detachable trimming and punching modules are respectively arranged in the respective universal installation areas of the upper die base and the lower die base, and the sheet material is cut and punched based on the trimming and punching modules; wherein the size and contour of the trimming and punching modules are customized according to project requirements.

[0010] In the above scheme, modular design is achieved by dividing the upper die base and the lower die base into several universal installation areas. This design method allows the mold to be quickly configured and adjusted according to the needs of different projects, which improves the flexibility and maintainability of the mold. The division of the universal installation area ensures that each module can be accurately aligned and work after installation, reducing the operation time. At the same time, the modular design simplifies the installation and disassembly operations of the mold, making the mold components between different projects universal and interchangeable, reducing resource waste. By standardizing the size and position of each installation area, a standardized process for mold design and manufacturing is achieved. This design method reduces the differences in size and weight when different manufacturers design and manufacture molds, and improves the consistency and standardization of the mold. The detachable trimming and punching module design allows the module to be customized according to project requirements, ensuring the versatility and compatibility of mold components. Even after the vehicle model is discontinued, the mold components can still be used in other projects, reducing resource waste. The design of the frame support mechanism and the wedge support mechanism ensures the stability and consistency of the sheet during processing, avoids the collapse of the sheet in the cutting corner area due to gravity, and improves the stability of sheet transportation. This design optimizes the production process, reduces processing time and scrap rate, and improves production efficiency.

[0058] Example 1

[0059] See also Figure 2 , Figure 2 The present invention provides a schematic structural diagram of a coiling and blanking die according to an embodiment of the present invention. The present invention provides a coiling and blanking die according to an embodiment of the present invention, comprising: an upper die seat and a lower die seat cooperating with each other, a frame support mechanism, an inclined wedge support mechanism and a trimming and punching module;

[0060] The upper die base and the lower die base are synchronously divided into a plurality of universal installation areas according to the universal vehicle structure; wherein the upper die base is slidably connected with the lower die base through guide mechanisms at four corners;

[0061] The frame supporting mechanism is disposed on the surface of the lower die seat along the contour of the lower die seat; wherein the frame supporting mechanism pushes the sheet material forward based on the roller arrangement;

[0062] The inclined wedge supporting mechanism is arranged at a preset position of the lower die seat, and the inclined wedge supporting mechanism provides support for the sheet material;

[0063] The detachable trimming and punching modules are respectively arranged in the respective universal installation areas of the upper die base and the lower die base, and the sheet material is cut and punched based on the trimming and punching modules; wherein the size and contour of the trimming and punching modules are customized according to project requirements.

[0064] In the embodiment of the present invention, a standardized die structure is formed for the same type of parts with similar sizes, the unwinding and blanking die is standardized in design, the position and size of the component installation area are solidified, the installation requirements of the same type of working parts with different sizes are met, and a universal upper and lower die base is provided. When a vehicle model is discontinued and withdrawn from the market, only the trimming and punching modules according to project requirements need to be scrapped, and the universal integrated unwinding and blanking die can be recycled and reused in new projects. New projects only need to develop corresponding trimming and punching modules according to new parts.

[0065] In one embodiment, the upper die base and the lower die base are synchronously divided into several universal installation areas according to the universal vehicle model structure, specifically including: the universal installation area includes a B-pillar cutting module installation area, a process punching module installation area, a C-pillar first cutting module installation area, and a C-pillar second cutting module installation area; wherein, the upper die base and the lower die base also include a cutting and separation knife block.

[0066] In the embodiment of the present invention, the upper die base and the lower die base are divided into a plurality of corresponding universal installation areas, including a B-pillar beveling module installation area, a process punching module installation area, a C-pillar first beveling module installation area, and a C-pillar second beveling module installation area. The B-pillar beveling module installation area is used to install the B-pillar beveling module to implement the beveling operation on the B-pillar portion of the part; the process punching module installation area is used to install the process punching module to implement the punching operation on the part; the C-pillar first beveling module installation area is used to install the C-pillar first beveling module to implement the first beveling operation on the C-pillar portion of the part; the C-pillar second beveling module installation area is used to install the C-pillar second beveling module to implement the second beveling operation on the C-pillar portion of the part; the cutting and separation knife block is used to completely separate the part from the sheet material. See. Figure 3 and Figure 4 , Figure 3 is a schematic structural diagram of an upper die base provided in one embodiment of the present invention, Figure 4 The schematic diagram of the structure of an upper die base provided in one embodiment of the present invention. In the embodiment of the present invention, a cutting module and a punching module of corresponding size and profile are arranged in each general installation area according to the project requirements. Furthermore, since a frame support mechanism is also arranged on the upper surface of the lower die base, in order to prevent the installed process punching module from hitting the upper support mechanism, the process punching module installation area is divided into four areas A\B\C\D, and the cutting and punching modules are installed in the four areas respectively.

[0067] By dividing different functional modules (such as B-pillar chamfering, process punching, C-pillar chamfering, and cutting and separation) into different installation areas, these modules can be easily replaced or adjusted. This design method allows the mold to be quickly configured and adjusted according to the needs of different parts. And the modular design allows each functional module to be maintained and replaced independently, reducing maintenance time and cost. For example, if a module is damaged or needs to be replaced, only the module needs to be replaced, without replacing the entire mold. By dividing different installation areas, unified standards and specifications can be formulated to ensure the consistency of each module during the design and manufacturing process.

[0068] In one embodiment, the upper mold base is slidably connected to the lower mold base through guide mechanisms at four corners, specifically including: the guide mechanism includes a guide column and a guide sleeve; wherein the guide column matches the guide sleeve; the four corners of the upper mold base are respectively equipped with the guide columns, and the four corners of the lower mold base are respectively equipped with the guide sleeves; the guide columns at the four corners are correspondingly inserted into the guide sleeves at the four corners, so that the upper mold base is slidably connected to the lower mold base.

[0069] In the embodiment of the present invention, guide posts are installed at the four corners of the upper die seat, and guide sleeves matching the guide posts are installed at the four corners of the lower die seat. The upper and lower die seats are connected through the guide posts and guide sleeves at the four corners. The guide posts are inserted into the guide sleeves to ensure the alignment and stability of the upper and lower die seats during the mold closing and mold opening process. Sliding connection refers to a connection method that allows parts to slide or move within a certain range. This connection method allows the upper die seat to slide on the guide posts, but still maintains a precise guiding effect during the sliding process. This design improves the operating accuracy and stability of the mold.

[0070] In one embodiment, the frame supporting mechanism is deployed on the surface of the lower die seat along the contour of the lower die seat, specifically including: the frame supporting mechanism includes a brush roller, a roller fixing seat, an aluminum alloy frame and a mounting seat; the aluminum alloy frame is deployed along the partition contour of each general working area in the lower die seat; the roller fixing seats are evenly arranged on the aluminum alloy frame; wherein, one brush roller is installed on each of the roller fixing seats; holes are downwardly dug at preset intervals on the two long sides of the lower die seat, a number of the mounting seats are arranged based on the hole digging area, and the aluminum alloy frame is fixed to the lower die seat through the mounting seats; wherein, a spring is arranged in the mounting seat.

[0071] See also Figure 5 , Figure 5The present invention is a schematic diagram of the structure of a frame-type support mechanism provided in one embodiment of the present invention. In the embodiment of the present invention, the roller fixing seat is used to fix the brush roller and install it on the aluminum alloy frame. The roller fixing seat has different lengths to meet the needs of different positions. The main function of the roller fixing seat is to fix the brush roller to ensure its stability and precise position on the aluminum alloy frame. Through the design of the fixing seat, the height and angle of the brush roller can be adjusted to meet the processing requirements of different sheet materials. The main function of the brush roller is to hold up the sheet material so that it contacts the brush roller when moving forward, thereby avoiding scratches on the surface of the sheet material. The brush roller contacts the sheet material by rotating to ensure that the sheet material remains flat and smooth during the processing. The aluminum alloy frame avoids the module installation area and is fixed to the lower die seat through 6 mounting seats arranged on the front and rear sides of the mold. The main function of the mounting seat is to fix the aluminum alloy frame and enable it to float up and down. The built-in spring is compressed by the upper die during operation, which allows the aluminum alloy frame and brush roller to float up and down, thereby adapting to sheets of different thicknesses and shapes, ensuring the flexibility and adaptability of the support mechanism during processing. When the sheet is placed on the die for processing, as the processing begins, the brush roller begins to rotate and hold up the sheet. As the sheet moves forward, it contacts the rotating brush roller, which ensures that the surface of the sheet remains flat and smooth through rotational friction to avoid scratches. Because the mounting seat has a built-in spring, when the upper die is compressed downward, the brush roller and the aluminum alloy frame can float up and down, which can adapt to sheets of different thicknesses and shapes, ensuring the flexibility and adaptability of the support mechanism during processing.

[0072] In one embodiment, the inclined wedge supporting mechanism is arranged at a preset position of the lower die seat, specifically comprising: the inclined wedge supporting mechanism is installed at preset edge positions of the C-pillar first angle cutting module installation area and the C-pillar second angle cutting module installation area, respectively; wherein the inclined wedge supporting mechanism comprises a brush roller, a roller mounting seat, a driving seat and a telescopic bracket; the roller mounting seat is connected to the telescopic bracket; wherein a brush roller is installed on the roller mounting seat; the driving seat is fixed to the lower surface of the upper die seat, and when the upper die seat and the lower die seat are closed, the driving seat is inserted into the telescopic bracket to make the brush roller move backward.

[0073] See also Figure 6 , Figure 6The structure diagram of a wedge support mechanism provided in one embodiment of the present invention. In the embodiment of the present invention, the wedge support mechanism is installed at a position close to the lower die seat in the C-pillar first angle cutting module installation area and the C-pillar second angle cutting module installation area. Preferably, considering the needs of the two angle cutting modules in practical applications, the installation positions of the two wedge support mechanisms are further optimized, and the wedge support mechanism in the C-pillar first angle cutting module installation area can be moved left and right according to different parts, and the adjustment distance is 250mm, so that it can adapt to the processing requirements of different parts. The position of the wedge support mechanism in the C-pillar second angle cutting module installation area is not adjustable and is fixed at a specific position. Specifically, the brush roller is usually cylindrical, and the surface is covered with a brush for contacting the sheet. The brush roller and the roller mounting seat are fixed together on the telescopic bracket. The main function of the brush roller is to hold up the sheet to prevent the sheet from collapsing under the action of gravity in the angle cutting area, and ensure that the sheet remains flat and smooth during processing. The wheel mounting seat is usually square or rectangular and has a structure for fixing the brush roller. The main function is to fix the brush roller to ensure its stability and position accuracy on the telescopic bracket. The telescopic bracket is fixed on the frame or fixed seat of the support mechanism. Its main function is to fix the brush roller and the roller mounting seat, and enable it to retreat backward when the upper and lower molds are closed, and return to the extended state when the upper and lower molds are opened, so as to ensure the support and lifting of the sheet. The drive seat is usually block-shaped and has a structure for inserting the telescopic bracket. Its main function is to insert the telescopic bracket when the upper and lower molds are closed, push the brush roller backward, and ensure that it does not affect the discharge of the corner cutting waste. When the upper and lower molds are opened, the brush roller is in the extended state, ready to hold up the sheet. When the sheet is placed on the mold for processing, after the first or second corner cutting of the C-pillar is completed, the support mechanism provides support to prevent the sheet from collapsing in the corner cutting area. When the upper and lower molds are closed, the drive seat is inserted into the telescopic bracket, and the brush roller retreats backward to ensure that it does not affect the discharge of the corner cutting waste. When the upper and lower molds are opened again, the brush roller returns to the extended state and continues to hold up the sheet being conveyed forward.

This design method enables the die to be quickly configured and adjusted according to the needs of different projects, thereby improving the flexibility and maintainability of the die. The division of the universal installation area ensures that each module can be accurately aligned and work after installation, thereby reducing the operation time. At the same time, the modular design simplifies the installation and disassembly operations of the die, thereby making the die components between different projects universal and interchangeable, thereby reducing resource waste. By standardizing the size and position of each installation area, a standardized process for die design and manufacturing is realized. This design method reduces the differences in size and weight when different manufacturers design and manufacture die, thereby improving the consistency and standardization of the die. The detachable trimming and punching module design enables the module to be customized according to the project requirements, thereby ensuring the universality and compatibility of the die components. Even after the vehicle model is discontinued, the die components can still be used in other projects, thereby reducing resource waste. The design of the frame support mechanism and the wedge support mechanism ensures the stability and consistency of the sheet metal during the processing process, thereby avoiding the collapse of the sheet metal in the cutting corner area due to gravity, thereby improving the stability of sheet metal transportation. This design optimizes the production process, reduces processing time and scrap rate, and improves production efficiency.

[0080] See also Fig.10 , Fig.10 The flowchart of a method for unwinding and blanking provided in an embodiment of the present invention is shown in FIG. The method for unwinding and blanking provided in an embodiment of the present invention is applicable to the unwinding and blanking die described in the above embodiment, and includes steps 101 to 104, and each step is specifically as follows:

[0081] Step 101: blanking the sheet material to be cut based on a preset uncoiling and blanking process flow; wherein the preset uncoiling and blanking process flow sequentially includes B-pillar corner cutting, process punching, C-pillar first corner cutting, C-pillar second corner cutting and cutting and separation.

[0082] In the embodiment of the present invention, first, the sheet to be cut is pre-processed, including positioning and fixing. Then, the B-pillar angle cutting, process punching, C-pillar first angle cutting, C-pillar second angle cutting and cutting and separation operations are performed in sequence according to the preset uncoiling and blanking process flow. The preset uncoiling and blanking process flow ensures that the sheet is cut and punched in a predetermined order, avoids operational errors and time waste, and improves production efficiency and consistency of sheet processing.

[0083] Step 102: According to project requirements, detachable trimming and punching modules are respectively arranged in the upper die base, the lower die base and each universal installation area; wherein the universal installation area includes a B-pillar trimming module installation area, a process punching module installation area, a C-pillar first trimming module installation area and a C-pillar second trimming module installation area.

[0084] In the embodiment of the present invention, according to the requirements of the specific project, detachable trimming and punching modules are respectively installed on the upper die base and the lower die base of the mold. These modules generally include a B-pillar trimming module, a process punching module, a C-pillar first trimming module, and a C-pillar second trimming module. The detachable design allows the trimming and punching modules to be quickly replaced and adjusted according to different project requirements, thereby improving the flexibility and versatility of the mold. The installation position of each module has been standardized in advance, ensuring that each module can be accurately aligned and work after installation.

[0085] Step 103: In the first blanking stage, the B-pillar corner cutting, the C-pillar first corner cutting and process punching are performed based on the trimming and punching module.

[0086] In an embodiment of the present invention, in the first blanking stage, the B-pillar beveling, the C-pillar first beveling and the process punching operations are performed in sequence by operating the mold. Specifically, first, the B-pillar beveling module performs beveling on the B-pillar area of ​​the sheet, then the C-pillar first beveling module performs the first beveling on the C-pillar area, and finally the process punching module performs the punching operation on the sheet. Blanking is a metal processing process used to cut the desired shape or holes on the sheet. The main function of the first blanking stage is to complete the main contour cutting of the sheet and the preliminary punching of the process holes. Through sequential operations, it is ensured that the sheet is carried out in accordance with the design requirements during the beveling and punching process, thereby ensuring the accuracy and consistency of sheet processing.

[0087] Step 104: In the second punching stage, the C-pillar is cut for the second time based on the trimming and punching module, and the cutting operation is performed by cutting and separating the blade block to divide the plate to be cut into different parts.

[0088] In the embodiment of the present invention, in the second blanking stage, the C-pillar area is firstly subjected to a second beveling by the C-pillar second beveling module, and the cutting of the C-pillar area is further completed. Then, the sheet material is cut by the cutting and separating knife block, and the entire sheet material is divided into different parts or components. The main function of the second blanking stage is to complete the final cutting and segmentation of the sheet material, and ensure that the sheet material is divided into different parts or components according to the design requirements. The design of the cutting and separating knife block makes the cutting operation more precise and efficient, and improves the precision and efficiency of sheet material cutting.

[0089] In one embodiment, the cutting operation performed by the cutting and separating blade block also includes determining the cutting length of the cutting and separating blade block according to the working parameters of the cutting and separating blade block, specifically: cutting length = step distance + cutting blade block width + blade block back support thickness + safety avoidance distance.

[0090] The setting of the cutting length is a key step in the unwinding and blanking process, which directly affects the design of the mold and the accuracy of sheet metal cutting. In the embodiment of the present invention, the cutting length of the cutting and separating blade block is also set according to the working data of the cutting and separating blade block. Fig.11 , Fig.11 The schematic diagram of the design description of a cutting length provided in one embodiment of the present invention. The cutting length D is the sum of the step distance L and the distance X2 between the waste and the edge of the sheet. This formula ensures that the cutting operation can accurately complete the cutting of the sheet, while taking into account the reasonable treatment of the waste and the safe avoidance of the sheet. The distance X2 between the waste and the edge of the sheet is determined by X1, and the smaller the length of X1, the smaller the cutting length D. This means that by optimizing the length of X1, the cutting length can be effectively controlled, thereby improving the cutting efficiency. The length of X1 is jointly determined by the width of the cutting blade block, the thickness of the blade block back support and the safe avoidance distance. The setting of these parameters needs to comprehensively consider the mold structure strength and operational safety. If the project design requirements require that the width of the cutting blade block must be ≥70mm, the thickness of the blade block back support must be ≥30mm, and the safe avoidance distance must be ≥10mm, the minimum value of X1 and X2 is 70+30+10=110mm, then the cutting length D=step distance L+110mm. The step distance L refers to the distance the workpiece or mold moves forward after each processing operation. The step distance determines the spacing of each processing operation, ensuring that the workpiece can be accurately arranged and formed during continuous processing. By setting the step distance reasonably, the utilization rate of materials can be maximized and the generation of waste can be reduced.
