Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and more specifically to a fast-aligning automotive door panel stamping die. Background Technology

[0002] Existing stamping dies mostly rely on guide grooves on the side walls of the sheet metal for positioning. This requires high dimensional accuracy around the sheet metal, resulting in high overall processing costs. Furthermore, traditional positioning methods require a separate positioning process or an additional power source to drive the positioning mechanism, which is cumbersome and inefficient. Especially for large automotive door panels, where the sheet metal is large and prone to movement, existing technologies cannot achieve rapid and accurate positioning while reducing the processing accuracy requirements of the sheet metal side walls, thus hindering the improvement of production efficiency.

It only requires ensuring the machining accuracy of the arc-shaped notches at the four corners to complete the accurate guidance, significantly reducing the difficulty and cost of the initial processing of the sheet metal and improving production economy.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the invention to this.

[0034] like Figures 1 to 12 As shown in the figure, the fast-aligning automotive door panel stamping die of this embodiment includes a lower die device 1 and an upper die device 2;

[0035] The lower mold assembly 1 includes a lower mold base 11; two guiding components 16 are spaced apart on one side of the lower mold base 11; each guiding component 16 includes a guiding shaft 161 and a guiding disk 162; the guiding shaft 161 is rotatably mounted on the lower mold base 11; a hinge shaft 1611 is provided on the outer wall of the guiding shaft 161; the guiding disk 162 has an asymmetrical structure, with the side of the guiding disk 162 closer to the center of the lower mold base 11 being heavier than the side farther from the center of the lower mold base 11; the guiding disk 162 is sleeved on the guiding shaft 161 and hinged to the hinge shaft 1611; the guiding shaft 161 is provided with a protruding pin 1612; the upper mold assembly... 2 includes an upper mold base 21; two drive rods 25 are spaced apart on one side of the upper mold base 21; each drive rod 25 is provided with a shaft hole 251; each shaft hole 251 is provided with a first spiral groove 252 and a second spiral groove 253 for cooperating with a protruding pin 1612; the pitch of the first spiral groove 252 is greater than the pitch of the second spiral groove 253; the lower end of the first spiral groove 252 vertically penetrates the drive rod 25; the upper end of the first spiral groove 252 is connected to the lower end of the second spiral groove 253; the upper end of the second spiral groove 253 and the lower end of the first spiral groove 252 are located on the same vertical line. Preferably, the ratio of the gravitational torque on the biased side of the guide disc 162 to the centrifugal torque expected to be generated during mold closing is 1:1.5~2.0, ensuring that the centrifugal force can stably overcome the gravity and drive the disc to tilt.

[0036] Specifically, in this embodiment of the rapid-alignment automotive door panel stamping die, the guide disc 162 has an asymmetrical structure, and the side closer to the center of the lower die base 11 is heavier than the side farther from the center of the lower die base 11. This causes the guide disc 162 to be in an inclined state when the guide shaft 161 is not rotating, that is, the heavier side hangs down and does not interfere with the sheet metal. In actual use, the sheet metal is placed on the upper die base 21, and each of the four corners of the sheet metal is provided with a rounded corner, the radius of which is the same as the outer radius of the guide disc. When the upper die device 2 and the lower die device 1 are closed, the protrusion 1612 of the guide shaft 161 enters the first spiral groove 252 through the opening end of the first spiral groove 252, thereby driving the guide shaft 161 to rotate. The guide shaft 161 drives the guide disc 162 to rotate, and the guide disc 162 overcomes its own gravity under the action of centrifugal force. The heavier side of the drooping part gradually tilts upward, thereby generating a pushing force on the arc-shaped notch of the sheet material through the tilted guide disc 162. Under the action of rotational centrifugal force, the guide disc 162 continuously pushes the sheet material to finely adjust its position. When the arc-shaped notch of the sheet material corresponds perfectly with the position of the guide disc 162, the guide disc 162 is precisely embedded in the arc-shaped notch, thereby limiting the two arc-shaped notches of the sheet material and completing precise guidance and positioning. At this time, the protrusion 1612 of the guide shaft 161 enters the second spiral groove 253 from the first spiral groove 252. Since the pitch of the first spiral groove 252 is greater than the pitch of the second spiral groove 253, the rotation speed of the guide shaft 161 and the guide disc 162 increases, so that the guide disc 162 maintains a horizontal rotation state under the action of rotational centrifugal force, so that the guide disc 162 cooperates with the arc-shaped notch of the sheet material to position the sheet material.

[0037] After the alignment and positioning are completed, the upper mold device 2 and the lower mold device 1 continue to close the mold to stretch, press, and punch the sheet metal, thereby processing the sheet metal into an automobile door panel workpiece. After the processing is completed, the upper mold device 2 and the lower mold device 1 open the mold, and the alignment disc 162 rotates in the opposite direction. After the mold is opened, that is, the protrusion 1612 of the alignment shaft 161 moves out of the first spiral groove 252 through the opening end of the first spiral groove 252, the alignment disc 162 stops rotating, and returns to the tilted state, so that the automobile door panel workpiece can be taken out.

[0038] This embodiment achieves precise positioning of the sheet metal by setting a guide shaft 161 with a protruding pin 1612 and a guide disk 162 hinged to the guide shaft 161 in the lower mold device 1, and a first spiral groove 252 and a second spiral groove 253 with a pitch smaller than the first spiral groove 252 in the upper mold device 2. Thus, when the mold is closed, the guide disk 162 engages with the arc notch of the sheet metal under the action of centrifugal force through the cooperation of the protruding pin 1612 with the first spiral groove 252 and the second spiral groove 253. This achieves precise positioning of the sheet metal without the need for additional positioning processes, and the guidance response speed is fast. It does not rely on the high-precision processing of the four sides of the sheet metal. It only needs to ensure the processing accuracy of the arc notch at the four corners to complete the precise guidance, which greatly reduces the difficulty and cost of the early processing of the sheet metal and improves the economic efficiency of production.

[0039] like Figure 4 and Figure 5 As shown, in some embodiments of the rapid-alignment automotive door panel stamping die of this embodiment, the lower die base 11 is provided with a limiting boss 141 on one side of the length and width directions, and at one end near one of the guiding components 16; the two limiting bosses 141 are perpendicular to each other. This embodiment, by providing two limiting bosses 141, initially limits the sheet metal during placement, thereby improving the efficiency of alignment and positioning.

[0040] like Figure 7 As shown, in some embodiments of the rapid-alignment automotive door panel stamping die of this embodiment, the center of the guide disc 162 is provided with a central hole 1621; the top of the guide disc 162 is provided with a conical surface 1622; the guide shaft 161 passes through the central hole 1621; the top surface of the guide disc 162 is recessed with an avoidance arc groove 1623 surrounding the central hole 1621; both ends of the hinge shaft 1611 extend into the avoidance arc groove 1623. This embodiment facilitates the assembly between the guide disc 162 and the guide shaft 161 through the above-described configuration.

[0041] like Figure 4 and Figure 5 As shown, in some embodiments of the fast-aligning automotive door panel stamping die of this embodiment, the lower die base 11 is provided with an L-shaped mounting arm 111 corresponding to each alignment component 16; the alignment shaft 161 has a disc portion 1613; the disc portion 1613 is rotatably disposed at the end of the mounting arm 111. This embodiment uses the above-described configuration to facilitate the installation of the alignment component 16.

[0042] like Figure 3 , Figure 8 , Figure 9 and Figure 12As shown, in some embodiments of the fast-aligning automotive door panel stamping die, the upper die base 21 is further provided with a pressing assembly 26; the pressing assembly 26 includes a pressing rod 261, a pressing slider 262, and a first spring 263; the top end of the pressing rod 261 is movably inserted through the upper die base 21; the bottom end of the pressing rod 261 is provided with a wedge-shaped pressing head 2611; the upper die base 21 is provided with guide plates 211 on both sides of the pressing rod 261; the guide plates 211 are provided with driving holes 212; the pressing slider 262 is provided with sliding pins 2621 on both sides; the sliding pins 2621 are movably embedded in the corresponding driving holes 212; the top of the pressing slider 262 is provided with a wedge-shaped surface 2622 that cooperates with the wedge-shaped pressing head 2611. In some embodiments of the fast-aligning automotive door panel stamping die, the bottom of the pressing slider 262 is provided with a rubber pad 264. In some embodiments of the fast-aligning automotive door panel stamping die of this embodiment, the drive hole 212 includes an inclined section and a vertical section; the lower end of the vertical section is connected to the upper end of the inclined section; initially, the sliding pin 2621 is located at the lower end of the inclined section.

[0043] If the edge of the sheet material is already against the limiting boss 141 when the sheet material is initially placed, the pressure slider 262 will cause the rubber pad 264 to slide relative to the sheet material, that is, the pressure slider 262 will not push the sheet material to move at this time.

[0044] Specifically, when the upper mold device 2 and the lower mold device 1 are closed, the rubber pad 264 contacts the sheet metal. As the upper mold device 2 moves further down, the pressure slider 262 is blocked and slides relative to the pressure rod 261. With the wedge-shaped pressure head 2611 and the wedge-shaped surface 2622 of the pressure slider 262 cooperate, the sliding pin 2621 moves upward along the inclined section, so that the pressure slider 262 drives the sheet metal to move towards the guide alignment component 16 through the rubber pad 264, so that one side of the sheet metal abuts against the limiting boss 141, achieving the initial positioning of the sheet metal. Until the sliding pin 2621 enters the vertical section from the inclined section, as the upper mold device 2 moves further down, the first spring 263 is compressed, and the pressure rod 261 moves relative to the upper mold base 21, thereby applying positive pressure to the sheet metal. At the same time, with the cooperation of the guide disc 162 and the arc notch, the sheet metal is continuously pushed to fine-tune its position, thereby realizing that the positioning and pressure action are automatically completed during the mold closing process without the need for an additional power source, simplifying the mold structure and processing flow.

[0045] like Figures 1 to 12As shown, in some embodiments of the fast-aligning automotive door panel stamping die of this embodiment, the lower die device 1 further includes a first lower punch 12 disposed on the lower die base 11, a second lower punch 13 movably sleeved on the outer periphery of the first lower punch 12, a third lower punch 14 movably sleeved on the second lower punch 13, and a fourth lower punch 15 movably embedded at a corner position of the first lower punch 12; the limiting boss 141 is disposed at a corner position of the third lower punch 14; the third lower punch 14 is provided with a first guide at each corner position corresponding to the two guiding components 16. A first guide groove 142 is provided; the guide disc 162 is located within the first guide groove 142; a second spring 131 with a stiffness greater than that of the first spring 263 is provided between the second lower punch 13 and the first lower punch 12; a third spring 143 with the same stiffness as the second spring 131 is provided between the third lower punch 14 and the first lower punch 12 to ensure that the second lower punch 13 and the third lower punch 14 move down synchronously, so that the sheet metal is subjected to uniform force during the stretching process and to avoid forming defects; a fourth spring 151 is provided between the fourth lower punch 15 and the first lower punch 12. In some embodiments of the fast-aligning automotive door panel stamping die of this embodiment, the upper die device 2 further includes a first upper punch 22 disposed on the upper die base 21, a second upper punch 23 elastically floating on the upper die base 21 and located on the outer periphery of the first upper punch 22, and a third upper punch 24 fixed on the upper die base 21 and located on the outer periphery of the second upper punch 23; the first upper punch 22 is used to cooperate with a fourth lower punch 15; the second upper punch 23 is used to cooperate with a second lower punch 13; the third upper punch 24 is used to cooperate with a third lower punch 14; the third upper punch 24 is provided with a second guiding groove 241 at the corner position corresponding to the two first guiding grooves 142; each second guiding groove 241 extends upwards. A connecting post 242 extends outward; the connecting post 242 is fixedly connected to the upper mold base 21; the driving rod 25 is embedded in the connecting post 242; the third upper punch 24 is provided with limiting grooves 243 corresponding to the two limiting bosses 141; a fifth spring 231 is provided between the second upper punch 23 and the upper mold base 21; the stiffness of the fifth spring 231 is greater than the stiffness of the second spring 131 or the third spring 143, so as to ensure that in the initial stage of mold closing, the second upper punch 23 and the third upper punch 24 first drive the second lower punch 13 and the third lower punch 14 to move down to complete the stretching, and then the upper mold base 21 continues to move down to compress the fifth spring 231, pushing the third upper punch 24 and the first upper punch 22 to complete the stamping and punching, so as to achieve orderly connection of processes.

[0046] Specifically, initially, the top surfaces of the first lower punch 12, the second lower punch 13, the third lower punch 14, and the fourth lower punch 15 are flush, and the sheet metal is supported on the support surface formed by the first lower punch 12, the second lower punch 13, the third lower punch 14, and the fourth lower punch 15. When the upper mold device 2 and the lower mold device 1 close, the rubber pad 264 contacts the sheet metal, and the pressure slider 262 drives the sheet metal to move towards the guide alignment component 16 through the rubber pad 264, so that one side of the sheet metal abuts against the limiting boss 141, thereby achieving the initial positioning of the sheet metal. Until the sliding pin 2621 enters the vertical section from the inclined section, the first spring 263 is compressed, thereby applying positive pressure to the sheet metal. At the same time, with the cooperation of the guide disc 162 and the arc notch, the sheet metal is continuously pushed to fine-tune its position, so that the positioning and pressure action of the sheet metal are completed during the mold closing process.

[0047] Next, the upper die device 2 moves further down, and the bottom surfaces of the second upper punch 23 and the third upper punch 24 contact the sheet metal. Since the stiffness of the fifth spring 231 is greater than that of the second spring 131 or the third spring 143, and the stiffness of the third spring 143 is the same as that of the second spring 131, the second lower punch 13 and the third lower punch 14 are simultaneously pressed down relative to the first lower punch 12. At this time, the second upper punch 23, the first lower punch 12, and the second lower punch 13 work together to stretch and shape the sheet metal. After the forming is completed, the second spring 131 is fully compressed, that is, the second lower punch 13 is restricted. Then the upper die holder 21 continues to move down, the fifth spring 231 is compressed, and the third upper punch 24 presses the third lower punch 14 to move downward relative to the second lower punch 13, thereby stamping the sheet metal. At the same time, the first upper punch 22 cooperates with the fourth lower punch 15, the fourth spring 151 is compressed, and the sheet metal is punched until the third lower punch 14 moves down to its position, thus completing the sheet metal processing and forming into an automotive door panel workpiece.

[0048] This embodiment enables the alignment and positioning, stretching, stamping, and punching processes to be completed in a single mold closing process, eliminating the need for intermediate transfer and clamping, ensuring the consistency of processing benchmarks, and significantly improving production continuity and efficiency.

[0049] like Figures 1 to 4 as well as Figure 8 As shown, in some embodiments of the fast-aligning automotive door panel stamping die of this embodiment, guide posts 213 extend from each of the four corners of the upper die base 21; guide sleeves 112 extend from each of the four corners of the lower die base 11; and the guide posts 213 can be movably inserted into the corresponding guide sleeves 112. Through the above-mentioned configuration, this embodiment achieves greater stability and higher structural reliability during the opening and closing of the upper die device 2 and the lower die device 1.
