[0026] The lower die assembly includes a lower supporting plate 23, and a lower die base 25 is connected to the upper part of the lower supporting plate 23 through a plurality of lower pads 24, and a first lower die pad 26 and a second lower die pad 28 arranged in parallel are connected to the upper part of the lower die base 25, a first concave mold plate 27 is connected to the upper part of the first lower die pad 26, and a second concave mold plate 29 is connected to the upper part of the second lower die pad 28; the first concave mold plate 27 is connected to the punching die 30, the first trimming die 31, the second trimming die 32, the first boss die 33, the second boss die 34 and the third boss die 35 in sequence from left to right; the second concave mold plate 29 is connected to the centering hole die 36, the hole extraction die 37, the third trimming die 38, the edge punching hole die 39, the leveling lower die 40 and the cutting and blanking die 41 in sequence from left to right.

[0027] The present invention, by arranging an upper die assembly and a lower die assembly, can complete multiple processes such as punching process holes, pre-cutting the shape, three consecutive convex forming middle bosses, one blank step, punching the middle hole of the boss, drawing the hole, two blank steps, punching the product shape, punching four side holes, leveling, three blank steps, cutting and blanking in one stamping process, thereby avoiding the need to use multiple molds, multiple equipments and multiple clamping in traditional production methods, reducing the number of times the workpiece is carried and positioned between different molds, reducing the errors caused by multiple positioning, simplifying the production process and shortening the production cycle.

[0028] Furthermore, in another embodiment, both the first stripper plate 6 and the second stripper plate 10 are connected with guide pins 43 for positioning the feeding distance of the steel strip 42 .

[0029] By setting the guide pin 43, it is possible to ensure that the position of the steel strip is accurately fed in the mold each time, thereby ensuring the precision of the stamping process and the stability of the product quality, and avoiding processing errors and defective products caused by deviations in the feeding position of the steel strip.

[0030] Furthermore, in another embodiment, the front and rear sides of the first lower die pad 26 and the second lower die pad 28 are connected with a plurality of floating pins 44 for placing the steel strip 42, and the top of the floating pin 44 passes through the first concave mold plate 27 and the second concave mold plate 29; the bottom of the floating pin 44 is fixedly connected with a floating pin spring 45.

[0031] By providing a floating pin 44 and a floating pin spring 45, the steel strip 42 can be kept in a certain suspended state under the action of the floating pin 44 during the stamping process. This can avoid friction damage to the steel strip 42 caused by direct contact with the first concave mold plate 27 and the second concave mold plate 29 during the stamping process. At the same time, it is convenient for the steel strip 42 to be unloaded smoothly after stamping, thereby improving production efficiency and product surface quality.

[0032] Furthermore, in another embodiment, a unloading spring 46 is provided between the upper mold base 2 and the first unloading pad 5 and the second unloading pad 9; the first unloading pad 5 and the first unloading plate 6, as well as the second unloading pad 9 and the second unloading plate 10 are all movably connected to the upper mold assembly through unloading screws 47; the first unloading pad 5 and the second unloading pad 9 are respectively connected to the first unloading plate 6 and the second unloading plate 10 through a plurality of unloading pad screws 62.

[0033] By arranging the unloading spring 46 and the unloading screw 47, the first unloading pad 5 and the first unloading plate 6, as well as the second unloading pad 9 and the second unloading plate 10 can exert a certain elastic force on the stamped steel strip 42 under the action of the unloading spring 46 during the stamping process, so as to facilitate the stripping of the stamped steel strip 42 from the punch, realize the unloading function, ensure the continuity of the stamping process, and improve the production efficiency; at the same time, the unloading pad screw 62 increases the connection stability between the first unloading pad 5 and the first unloading plate 6, as well as the second unloading pad 9 and the second unloading plate 10.

[0034] Furthermore, in another embodiment, the opposing surfaces of the leveling upper die 22 and the leveling lower die 40 are both threadedly connected with a plurality of leveling bolts 48 .

[0035] By setting multiple leveling bolts 48 and adjusting the tightening depth of each leveling bolt 48, the gap and pressure distribution between the leveling upper die 22 and the leveling lower die 40 can be changed, thereby flexibly adjusting the leveling effect of the stamping parts to meet the high-precision requirements of the processing of the new energy vehicle body cover.

[0036] Furthermore, in another embodiment, the four corners of the lower die base 25 are respectively fixedly connected with outer guide pillars 49 , and the four corners of the upper die base 2 are respectively fixedly connected with outer guide sleeves 50 that cooperate with the outer guide pillars 49 .

[0037] By setting the cooperation of the outer guide pin 49 and the outer guide sleeve 50, precise guidance is provided for the closing process of the upper mold assembly and the lower mold assembly, ensuring that the upper and lower molds can be accurately aligned during the stamping process, avoiding misalignment of the mold during stamping, and improving the stamping accuracy and the service life of the mold.

[0038] Furthermore, in another embodiment, the four corners of the first upper template 4 and the second upper template 8 are fixedly connected with inner guide pillars 51, and the first unloading plate 6, the second unloading plate 10, the first concave template 27 and the second concave template 29 are fixedly connected with inner guide sleeves 52 that cooperate with the inner guide pillars 51.

[0039] By providing the inner guide pin 51 and the inner guide sleeve 52, the guiding accuracy between the internal components of the mold is enhanced, especially during the relative movement between the first stripper plate 6 and the first concave mold plate 27, and between the second stripper plate 10 and the second concave mold plate 29, the movement accuracy and stability of the first stripper plate 6 and the second stripper plate 10 are ensured, thereby improving the reliability of the stamping process and the product quality.

[0040] Furthermore, in another embodiment, the upper die base 2 is connected to the first upper die pad 3 and the first upper die plate 4, and to the second upper die pad 7 and the second upper die plate 8 through a plurality of upper die fixing screws 53 and an upper die fixing pin 54; the lower die base 25 is connected to the first lower die pad 26 and the first concave die plate 27, and to the second lower die pad 28 and the second concave die plate 29 through a plurality of lower die fixing screws 55 and a lower die fixing pin 56.

[0041] By providing the upper die fixing screw 53 and the upper die fixing pin 54, as well as the lower die fixing screw 55 and the lower die fixing pin 56, it is possible to ensure that the connection between the components of the upper die assembly and the lower die assembly is firm and reliable, and no loosening or displacement will occur during the stamping process, thereby ensuring the stability of the mold and the accuracy of the stamping process.

[0042] Furthermore, in another embodiment, the upper and lower ends of the lower foot 24 are fixedly connected to the lower die base 25 and the lower supporting plate 23 by lower foot fixing screws 57 , respectively.

[0043] By setting the lower foot fixing screws 57, the stability of the support of the lower foot 24 to the lower die base 25 is ensured, so that the lower die base 25 can be firmly installed on the lower support plate 23, providing a stable foundation for the entire mold, which helps to improve the stability and reliability of the mold during the stamping process.

[0044] Furthermore, in another embodiment, the upper die base 2 and the lower die base 25 are connected to outer limit blocks 59 arranged opposite to each other through first limit fixing screws 58; the first concave mold plate 27 and the second concave mold plate 29 are connected to inner limit blocks 61 through second limit fixing screws 60.

[0045] By setting the outer limit block 59 and the inner limit block 61, the stroke of the mold can be limited to prevent the upper mold assembly and the lower mold assembly from over-closing during the mold closing process, thereby avoiding damage to the mold due to excessive extrusion, and also helping to ensure the thickness and accuracy of the stamping parts.

[0046] The working principle of one embodiment of the present invention is as follows:

[0047] First, the steel strip 42 is placed on the floating pins 44 at the front and rear sides of the first lower die pad 26 and the second lower die pad 28 , and the floating pin spring 45 at the bottom of the floating pin 44 is in a natural state to provide support for the steel strip 42 .

[0048] The press drives the upper die assembly to move downward, and the outer guide sleeves 50 at the four corners of the upper die base 2 are precisely guided along the outer guide pillars 49 at the four corners of the lower die base 25, ensuring that the upper die assembly and the lower die assembly are accurately molded. At the same time, the inner guide pillars 51 at the four corners of the first upper die plate 4 and the second upper die plate 8 respectively cooperate with the inner guide sleeves 52 on the first stripper plate 6, the second stripper plate 10, the first concave die plate 27 and the second concave die plate 29, further improving the relative position accuracy of the various components inside the mold.

[0049] As the upper die assembly continues to descend, the discharge spring 46 is compressed, and the first discharge plate 6 and the second discharge plate 10 first contact and press the steel belt 42, and the stamping process begins at this time:

[0050] Punching process: The punching punch 11 on the first upper template 4 cooperates with the punching die 30 on the first concave template 27 to punch out the required guide holes and a part of the side holes on the steel strip 42; the setting of the guide holes facilitates the insertion of the guide needles 43 on the first unloading plate 6 and the second unloading plate 10 to position the steel strip 42.

[0051] Trimming process: the first trimming punch 12 cooperates with the first trimming die 31, and the second trimming punch 13 cooperates with the second trimming die 32 to perform trimming operations on the steel strip 42, and punch out another part of the edge holes to initially form the initial contour of the automobile body cover.

[0052] Embossing process: the first embossing punch 14 cooperates with the first embossing die 33 , the second embossing punch 15 cooperates with the second embossing die 34 , and the third embossing punch 16 cooperates with the third embossing die 35 to form a convex structure on the steel strip 42 .

[0053] One-step process: After the embossing process is completed, the upper die assembly continues to descend and closes with the lower die assembly, but no actual stamping action occurs at this stage. Setting this step process allows the material to have a certain amount of time to release internal stress, avoiding abnormal material deformation due to stress concentration in the subsequent punching process, and ensuring the processing accuracy of the punching process.

[0054] Punching and drawing hole process: the punch 17 and the punch die 36 on the second upper template 8 cooperate to punch out the middle hole, and the drawing hole punch 18 and the drawing hole die 37 cooperate to complete the drawing hole operation.

[0055] Secondary idle step process: After the punching and hole-drawing processes are completed, the upper mold assembly continues to descend to close the mold, and no stamping action is performed at this time; this idle step process allows the material that has undergone punching and hole-drawing time to adjust its internal stress state, avoiding poor trimming quality due to uneven stress in the subsequent third trimming process, ensuring that the third trimming process can proceed smoothly.

[0056] The third trimming process: The third trimming punch 19 cooperates with the third trimming die 38 to further trim the steel strip 42, further accurately trim the edge of the product, and ensure that the flatness and dimensional accuracy of the edge meet the standards.

[0057] Punching hole process: The punching hole punch 20 cooperates with the punching hole die 39 to punch out the required holes around the edge of the steel strip 42.

[0058] Leveling process: When the stamping reaches a specific position, the leveling upper die 22 cooperates with the leveling lower die 40 to level the stamped part by adjusting the leveling bolts 48 on the opposite surfaces to ensure its flatness.

[0059] Three empty steps: After the leveling process is completed, the upper die assembly descends again to close the mold with the lower die assembly. There is no actual stamping action in this stage. This empty step can make the internal stress of the leveled material more evenly distributed, avoid uneven cutting surface or deformation of stamping parts due to stress in the cutting and blanking process, and improve the final quality of the product.

[0060] Cutting and blanking process: The cutting and blanking punch 21 cooperates with the cutting and blanking die 41 to cut and separate the processed new energy vehicle shell cover from the steel strip 42.

[0061] After the stamping is completed, the press drives the upper die assembly to move upward, and the unloading spring 46 recovers its elastic deformation, pushing the first unloading pad 5 and the second unloading pad 9, thereby making the first unloading plate 6 and the second unloading plate 10 unload the stamped parts or waste from the punch. At the same time, the floating pin 44 moves upward under the action of the floating pin spring 45, lifting the steel strip 42 to facilitate the subsequent feeding of the steel strip 42.

[0062] During the entire stamping process, the upper die seat 2 and the lower die seat 25 are connected by the outer limit block 59 through the first limit fixing screw 58, and the first concave die plate 27 and the second concave die plate 29 are connected by the inner limit block 61 through the second limit fixing screw 60, which limits the stroke of the die, prevents the upper die assembly and the lower die assembly from being over-closed, protects the die and ensures the quality of the stamped parts. Afterwards, the steel strip 42 is fed forward a certain distance through the external feeding device to prepare for the next stamping process, and the cycle is repeated to achieve continuous production of the new energy vehicle housing cover.

[0063] According to the description and drawings of the present invention, those skilled in the art can easily manufacture or use a new energy vehicle housing cover plate mold of the present invention, and can produce the positive effects recorded in the present invention.
