Description

Technical Field

[0001] The present invention relates to the technical field of automotive component forming, and more specifically, to a manufacturing method for cold stamping ultra-high strength steel beam components. Background Art

[0002] Automobile lightweighting is the future development direction of automobiles. In recent years, ultra-high strength steel has become the preferred material for the green development of the automotive industry. As the tensile strength of the steel increases, the springback amount of the product becomes larger and the springback compensation of the process becomes more difficult. Especially when the tensile strength increases to more than 1180 Mpa, serious precision problems such as severe concave, springback, and distortion occur in the product, and the existing process technology solutions are difficult to meet the quality requirements of the product.

[0003] Among them, the existing process technology solutions mainly use suspended wedges to adopt a negative angle compensation strategy for springback compensation. The entire process technology solution mainly has the following 4 disadvantages: (1) The structure of the suspended wedge is complex, the processing and assembly debugging cycle is long, the mold cost is high, the inspection and maintenance cost during mass production increases, and the probability of mold problems is relatively high due to the complex structure; (2) When compensating for springback during side shaping, the entire side wall and flange will be formed twice, resulting in unstable product accuracy; (3) When compensating for springback during side shaping, the entire side wall and flange need to be re-ground for each round of springback rectification, resulting in a large amount of work for fitters and a long rectification cycle; (4) The springback amount of ultra-high strength steel is large, and the large negative angle compensation during side shaping results in insufficient strength of the lower die insert, making it impossible to meet the mass production requirements.

[0034] The following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments, enabling those skilled in the art to implement it with reference to the text of the specification.

[0035] It should be understood that terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0036] As Figures 1 - 3 shown, the present invention provides a manufacturing method for cold stamping ultra-high strength steel beam components, including: a first process, which is the OP05 process (blanking + punching), accurately blanking the product side line in place and punching the side wall holes of the product; The second process is the OP10 process (preforming), which forms the main surface and flange of the product in place and preforms the side wall. The third process is the OP20 process (offset flanging), which controls the springback of the side wall by using the offset forming process. The fourth process is the OP30 process (punching), which punches the remaining holes on the main surface of the product.

[0037] The present invention provides a manufacturing method for cold stamping ultra-high strength steel beam parts. For the springback of the main surface, a direct springback compensation measure is taken in the OP10 preforming process; for the springback of the flange surface, a direct springback compensation measure is taken in the OP10 preforming process. Further, the springback of the side wall is reduced by controlling the offset amount A and the size of the preformed R2 in the OP10 preforming process (the side wall spreading angle Q needs to consider the feeding interference problem. The length of the A section line is the key parameter for offset forming, and the size of R2 is the key parameter for springback control. At the same time, the distance from the stop line of R2 to the hole S also needs to be considered to ensure the flatness of the punching surface). Then, the accuracy requirement is achieved through the positive flanging angle compensation in the OP20 process. The flanging tool block 41 in the third process includes an R angle, that is, the flanging tool block 41 in the OP20 process includes an R angle (i.e., secondary forming is required for the R angle).

[0038] The range of the above key parameter A is selected as 8 - 14 mm, and the range of R2 is selected as 4 - 10 mm. Simulation is carried out in the CAE software. Preferably, the value of A is 11.35 mm; preferably, the value of R2 is 4.25 mm to meet the manufacturing requirements of the product.

[0039] The present invention provides a manufacturing method for cold stamping ultra-high strength steel beam parts. By mainly using the offset forming technology, the springback amount of the side wall of the ultra-high strength steel beam parts is greatly reduced, and then the accuracy requirement of the product is achieved through the positive flanging process technology. The manufacturing method of the present invention has the following main advantages: (1) The die structure of the offset forming process is relatively simple, the processing, assembly and commissioning cycle is shortened, and the inspection and maintenance cost during mass production is relatively low. The positive flanging structure is simple and the probability of die problems is relatively small. (2) When controlling the springback of the side wall, the flange surface of the product will not undergo secondary forming, and the accuracy of the product is stable. (3) When controlling the springback of the side wall, the rectification workload for each round is greatly reduced, and the rectification cycle can be effectively shortened. (4) The offset forming process has a small springback amount, and the strength of the lower die insert 2 is effectively guaranteed.

[0040] Such as Figures 4 - 9As shown, further, in the above-mentioned third process, the die device 100 performs a misalignment forming process on the product 200. The die device 100 can preferably achieve the misalignment forming of the product 200. Specifically, the die device 100 includes a lower die base 1, a lower die insert 2, an upper die insert 3, and an upper die base 4. Among them, the lower die insert 2 is installed on the lower die base 1, and the upper die insert 3 is movably installed in the upper die base 4. Here, two flanging blade blocks 41 are installed in the upper die base 4, and the upper die insert 3 is located between the two flanging blade blocks 41. The product 200 is on the lower die insert 2. Therefore, when the upper die base 4 moves downward to close the die with the lower die base 1, the upper die insert 3 first contacts and punches the product 200 to prevent the product 200 from moving. Then, as the upper die base 4 continues to move downward, the flanging blade blocks 41 on both sides of the upper die insert 3 then also contact the product 200. When the upper die base 4 continues to move downward, the flanging blade blocks 41 complete the downward punching and flanging of the product 200, so that the lower die insert 2, the upper die insert 3, and the two flanging blade blocks 41 complete the punching of the product 200. Moreover, the misalignment forming process is adopted between the lower die insert 2 and the upper die insert 3 to control the side wall springback.

[0041] Further, a chute 42 is opened in the upper die base 4, and the upper die insert 3 is slidably installed in the chute 42. Moreover, an upper retaining seat mechanism 43 for abutting against the upper die insert 3 is installed in the chute 42. Here, the upper retaining seat mechanism 43 provides elastic support for the upper die insert 3, and the upper die insert 3 can preferably fix the product 200 to prevent the product 200 from moving and affecting the punching effect.

[0042] Further, the above-mentioned upper retaining seat mechanism 43 includes a spring seat 44 and an upper baffle 45. Here, the spring seat 44 has a plurality of spring units 441, and the spring seat 44 is also provided with a guide block 442. In the chute 42, a spring groove 421 corresponding to the spring unit 441 and a guide groove 422 corresponding to the guide block 442 are installed. The upper baffle 45 is installed on the top of the upper die base 4 and abuts against the plurality of spring units 441. Here, when the upper die insert 3 contacts and abuts against the product 200, as the upper die base 4 moves downward, the internal spring units 441 provide elastic support for the upper die insert 3. Here, the spring units 441 are preferably nitrogen springs; and the guide block 442 provides a guiding function for the movement of the upper die insert 3, making the up and down movement of the upper die insert 3 smoother and avoiding jamming.

[0043] Furthermore, there is a misaligned convex body 31 at the bottom of the upper die insert 3. Correspondingly, there is a misaligned groove 201 on the lower die insert 2. The misaligned groove 201 corresponds to the misaligned convex body 31. Therefore, after the upper die insert 3 contacts the product 200, the product 200 is stamped and fixed to the lower die insert 2. Through the cooperation of the misaligned groove 201 and the misaligned convex body 31, the misaligned forming process of the product 200 is realized. As the upper die base 4 and the lower die base 1 are closed, two flanging blade blocks 41 perform flanging on the product 200, thereby achieving the purpose of the third process.

[0044] Exemplary quick-release module As Figures 10 - 16 shown, further, in some embodiments of the present invention, the specific structure of the lower die insert 2 is provided. Here, the lower die insert 2 of this structure includes a plurality of lower modules 21. Here, the plurality of lower modules 21 are sequentially installed on the lower die base 1. Since a large number of products need to be produced, the mold will be worn during the use process, resulting in a decrease in accuracy. Therefore, it is necessary to often disassemble the mold for repair and replacement. Generally speaking, the wing seats 211 on both sides of the lower module 21 are fixed in the threaded holes of the lower die base 1 by screws. However, due to the above situation that requires frequent disassembly, the phenomenon of stripped threads is inevitable. Therefore, here, the quick-release module 22 is used to replace the screw fixation to avoid vibration when the upper die insert 3 contacts the lower die insert 2 for the misaligned forming of the product 200, or causing the lower die insert 2 to loosen and affecting the misaligned forming quality of the product 200.

[0045] Specifically, the wing seat 211 of the lower module 21 is installed on the lower die base 1 through the quick-release module 22. Among them, the quick-release module 22 includes a quick-release shaft 23, a quick-release sleeve 24, and a quick-release cap 25. A cap groove corresponding to the quick-release cap 25 is opened on the lower die base 1, so the quick-release cap 25 can be fixedly installed in the cap groove. And an opening groove corresponding to the quick-release sleeve 24 is opened on the wing seat 211 of the lower module 21. The quick-release sleeve 24 extends downward through the opening groove into the quick-release cap 25. Then, the quick-release shaft 23 needs to be installed into the quick-release sleeve 24 and connected to the quick-release cap 25. Here, by pressing the lower module 21 on the quick-release cap 25, the weight of the lower module 21 acts on the quick-release cap 25, so that the quick-release cap 25 fixes the quick-release shaft 23 and the quick-release sleeve 24. Therefore, there is no need for threaded connection between the quick-release shaft 23, the quick-release sleeve 24, and the quick-release cap 25, and it is also convenient for subsequent disassembly to repair and replace the lower module 21.

[0046] Exemplary quick-release cap As Figures 11 - 15As shown, further, some embodiments of the present invention provide a specific structure of the quick-release cap 25, wherein the quick-release cap 25 has a first inner cavity 251, and the inner wall of the first inner cavity 251 has a plurality of second inner cavities 252, and a plurality of first springs 254 and an inner pressure plate 255 are installed in the first inner cavity 251, and the plurality of first springs 254 abut against the inner pressure plate 255, and the second inner cavity 252 is connected to the upper surface of the quick-release cap 25 through a vertical hole 253, and a pressure plate 255 is installed in the vertical hole 253. Rod 256, a rocker member 257 is also installed in the second inner cavity 252, and the rocker member 257 can swing up and down in the second inner cavity 252 through the shaft body 2521, so one end of the rocker member 257 corresponds to the bottom of the inner pressure plate 255, and the other end corresponds to the pressure rod 256, and a plurality of T-shaped opening grooves 242 are also opened on the sleeve body 241 of the quick release sleeve 24, and T-shaped pressure blocks 243 are installed in the T-shaped opening grooves 242, and the T-shaped pressure blocks 243 correspond to the inner pressure plate 255 and are used to fix the quick release shaft 23.

[0047] Here, after the lower module 21 presses the above-mentioned pressure rod 256, the pressure rod 256 pushes against the tilting rod 257, so that one end of the tilting rod 257 is tilted and pushes against the inner pressure plate 255, and then the quick-release shaft 23 is installed in the quick-release sleeve 24. After the quick-release shaft 23 enters the quick-release sleeve 24, it pushes against multiple T-shaped pressure blocks 243, so that the T-shaped pressure blocks 243 will move into the first inner cavity 251 and press against the inner pressure plate 255, and then the multiple T-shaped pressure blocks 243 will fix the quick-release shaft 23 in the quick-release sleeve 24, so that the quick-release cap 25 fixes the quick-release shaft 23 and the quick-release sleeve 24, and the quick-release shaft 23 can be pulled out of the quick-release sleeve 24 later, so that the quick-release shaft 23 and the quick-release sleeve 24 can be separated. There is no need for threaded connection between the quick-release caps 25 to avoid thread slippage, and then it is also convenient to disassemble and repair and replace the lower module 21 later.

[0048] In addition, the second inner cavity 252 is also provided with a tension spring 2531, which is connected to the bottom of the pressure rod 256. When the quick-release shaft 23 is pulled out and the lower module 21 is moved upward, the pressure rod 256 extends upward from the vertical hole 253 under the action of the tension spring 2531, and the multiple first springs 254 inside push down against the inner pressure plate 255, and then the inner pressure plate 255 drives the multiple T-shaped pressure blocks 243 to return to the T-shaped opening groove 242, and the other end of the tilting rod 257 also tilts upward.

[0049] Further, in some embodiments of the present invention, the T-shaped pressing block 243 is connected in the T-shaped opening groove 242 through a plurality of second springs 244, so that the T-shaped pressing block 243 has a pulling force to return to the T-shaped opening groove 242. Therefore, a plurality of T-shaped pressing blocks 243 can abut and fix the pressing rod 256 entering the interior to prevent it from loosening. Further, a first wedge surface facing the inner pressing disc 255 is provided at the upper end of the T-shaped pressing block 243, and a second wedge surface corresponding to the first wedge surface is provided on the inner pressing disc 255. Therefore, when the T-shaped pressing block 243 moves inward to the inner pressing disc 255 under the action of the pressing rod 256, the two abut against each other, so that a plurality of T-shaped pressing blocks 243 can more firmly abut and fix the pressing rod 256 entering the interior to prevent it from loosening.

[0050] As Figure 16 shown, further, in some embodiments of the present invention, a guiding protrusion 245 corresponding to the T-shaped opening groove 242 is provided on the inner wall of the quick-release sleeve 24, and a guiding groove 231 corresponding to the guiding protrusion 245 is provided on the outer wall of the quick-release shaft 23. Among them, the guiding groove 231 is divided into three sections: the first section groove 2311, the second section groove 2312, and the third section groove 2313. The second section groove 2312 is located between the first section groove 2311 and the third section groove 2313. In this way, when the quick-release shaft 23 enters the quick-release sleeve 24, the guiding protrusion 245 enters the first section groove 2311 through the third section groove 2313 and the second section groove 2312, so that the third section groove 2313 in the quick-release shaft 23 corresponds to the T-shaped pressing block 243, which facilitates the installation of the quick-release shaft 23 and also prevents the quick-release shaft 23 from moving axially, thereby fixing the lower module 21 on the lower die base 1.
