Description

Technical Field

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the desired parts.

[0003] When designing and manufacturing stamping dies, the following steps are usually taken: determine whether the product structure is suitable for the stamping process, use software to design the die structure, process the die components through CNC machine tools, EDM, wire cutting and other equipment, assemble the processed die components, and debug them on the stamping machine to ensure that the die can produce qualified products, conduct trial production, and verify the reliability of the die and the quality of the product.

[0004] The prior art discloses some invention patents in the field of stamping die technology, among which the invention patent with publication number CN114130898B discloses a stamping die, including an upper die assembly, a lower die assembly and a core pressure assembly, the upper die assembly includes an upper die base for moving along a first direction and an upper slider installed on the upper die base, the core pressure assembly includes an outer core pressure, a base, a lower slider, an inner core pressure and an insert. The stamping die provided by the present invention provides an outer pressure core for pressing the workpiece along a first direction and an inner pressure core that can extend out along a second direction inside the outer pressure core and press the workpiece, so that the workpiece can obtain two pressing and clamping forces along the first direction and along the second direction, thereby preventing the workpiece from moving during the stamping process along the first direction or the second direction, thereby improving the processing accuracy and quality of the workpiece, and the inner pressure core is slidably arranged inside the outer pressure core, thereby making the structure of the present die more compact and reasonable; at the same time, when the side outer panel is processed by the present die, the side stamping quality of the fuel filler port can be improved. The technical solution still has some shortcomings in the process of application, so that the workpiece can obtain two pressing and clamping forces along the first direction and along the second direction, thereby preventing the workpiece from moving during the stamping process along the first direction or the second direction, thereby improving the processing accuracy and quality of the workpiece, but when the stamping part is demolded, if the stamping part is subjected to uneven force, the stamping part is prone to metal property changes, thereby reducing the accuracy and quality of the stamping part.

[0047] Specifically, the pressure relief member A404 has the same structure as the pressure relief member B411. The pressure relief member A404 includes a slider A4041 slidably connected to the slide groove A403. The end of the slider A4041 is connected to a pressure relief spring A4043. The slider A4041 is elastically supported and connected to the inner wall of the slide groove A403 through the pressure relief spring A4043. The slider A4041 is connected to an adapter frame A4042. The inner side of the adapter frame A4042 is rotatably connected to a transfer connecting rod 4044.

[0048] The pressure relief member A404 also includes a slider B4046 slidably connected to the slide groove B413, the end of the slider B4046 is connected to a pressure relief spring B4047, the slider B4046 is elastically supported and connected to the inner wall of the slide groove B413 through the pressure relief spring B4047, the bottom of the slider B4046 is connected to an adapter frame B4045, and the inner side of the adapter frame B4045 is rotatably connected to the other end of the transfer connecting rod 4044;

[0049] A connecting shaft 405 is rotatably connected between the transfer connecting rod 4044 of the pressure relief member A404 and the transfer connecting rod 4044 of the pressure relief member B411. A buffer assembly 5 for cooperating with the die 3 to complete stamping production is arranged directly above the die 3. The buffer assembly 5 includes a connecting seat 501. A piston groove 502 is provided at the bottom of the connecting seat 501. A partition plate 503 is clamped in the piston groove 502. A plurality of through holes A are provided on the partition plate 503. Buffer shafts 505 are sleeved in the plurality of through holes A. The bottom ends of the plurality of buffer shafts 505 are connected to the same punch 506 for stamping production in cooperation with the die 3.

[0050] The top ends of the multiple buffer shafts 505 are connected to the same buffer plate 507 , which is sleeved in the piston groove 502 , and the buffer plate 507 is connected to multiple buffer springs 504 , which are elastically supported and connected to the top of the piston groove 502 via the multiple buffer springs 504 .

[0051] The specific implementation method is as follows: first, the material to be punched is placed on the die 3, and then the hydraulic cylinder 805 is controlled to stretch. The hydraulic cylinder 805 drives the buffer assembly 5 to descend through the top cover 801 and the slider C803. Before the punch 506 contacts the material to be punched on the die 3, the directional shaft connected to the bottom of the coupling seat 501 will dock with the buffer shaft 412. The coupling seat 501 presses the buffer plate 402 through the directional shaft and the buffer shaft 412. The buffer plate 402 slides downward in the buffer cylinder 401 and squeezes the buffer piece A404 and the buffer piece B411. The transfer connecting rod 4044 of the buffer piece B411 and the transfer connecting rod 4044 of the buffer piece A404 are connected through the coupling. The junction shaft 405 rotates crosswise, and at the same time, one end of the transfer link 4044 rotates around the transfer frame B4045, and pushes the slider B4046 to slide in the slide groove B413 through the transfer frame B4045, squeezing the pressure relief spring B4047 to make it elastically deformed, and the other end of the transfer link 4044 rotates around the transfer frame A4042, and pushes the slider A4041 to slide in the slide groove A403 through the transfer frame A4042, squeezing the pressure relief spring A4043 to make it elastically deformed. During this process, the one-way valve A406 opens, and air is sucked into the space above the pressure relief plate 402 in the pressure relief cylinder 401 through the intake pipe, and the air intake per unit time of the intake pipe is small.

[0052] Specifically, the punch 506 is provided with a plurality of suction holes 6, and a carrying assembly 7 for vacuum adsorption of the finished stamping part is inserted and connected in the plurality of suction holes 6. The carrying assembly 7 includes a suction cup 701 inserted and connected in the plurality of suction holes 6, and a telescopic tube is connected to the suction cup 701. Through holes B are provided at positions corresponding to the plurality of telescopic tubes on the partition plate 503, and the other ends of the plurality of telescopic tubes are respectively clamped in the plurality of through holes B. A through hole C702 is provided on the telescopic tube corresponding to the upper part of the partition plate 503, and the same through tube 703 is clamped in the plurality of through holes C702 on the same side, and positions on the through tube 703 corresponding to both sides of the telescopic tube Each of the through pipes 703 is provided with air holes 704, and the corresponding two air holes 704 in the through pipe 703 are respectively provided with a one-way valve C705 and a one-way valve D706, and an adjusting shaft 707 is connected between the one-way valve D706 and the one-way valve C705, for pulling or pushing the one-way valve C705 and the one-way valve D706 to move between the two air holes 704. The end of the through pipe 703 is externally connected to the outer wall of the coupling seat 501, and an adjusting hole is provided at the port of the through pipe 703. The end of the adjusting shaft 707 passes through the adjusting hole and is connected with a supporting spring A708, and the adjusting shaft 707 is elastically supported and connected to the through pipe 703 through the supporting spring A708.

[0053] The specific implementation method is as follows: after the punch 506 completes the stamping process on the material to be stamped, the hydraulic cylinder 805 is controlled to retract, and the downward pressure of the directional shaft on the pressure relief shaft 412 gradually weakens, and the pressure relief spring A4043 and the pressure relief spring B4047 begin to perform elastic reset movement. Under the joint action of the pressure relief spring B4047 and the pressure relief spring A4043, the pressure relief plate 402 will be pushed to move upward, and the pressure relief plate 402 squeezes the air that enters the pressure relief cylinder 401 through the one-way valve A406, and the one-way valve B408 opens. The air in the pressure relief cylinder 401 flows into the diversion pipe 409 through the manifold 407, the one-way valve B408 and the bridge pipe 410. After the air is diverted by the diversion pipe 409, it is quickly filled into the interior of the die 3. Under the action of the air, it can have a certain demoulding effect on the stamping part. In the subsequent stage of the retraction movement of the hydraulic cylinder 805, the buffer spring 504 performs elastic reset movement.

[0054] Specifically, the coupling seat 501 is connected to a stamping assembly 8 for driving itself to perform lifting movements. The stamping assembly 8 includes a top cover 801 connected to the coupling seat 501. A plurality of slide grooves C802 are provided at the bottom of the top cover 801. A slider C803 is slidably connected in the slide groove C802. A support spring B804 is connected to the end of the slider C803. The slider C803 is elastically supported and connected to the inner wall of the slide groove C802 through the support spring B804. The slider C803 is connected to the coupling seat 501. A hydraulic cylinder 805 is installed on the top cover 801. A wedge seat 11 is provided on one side of the coupling seat 501. A caster A9 is connected to the end of the adjusting shaft 707 corresponding to the wedge seat 11. A notch is provided on the wedge seat 11 at a position corresponding to the caster A9. The coupling seat 501 is connected to a caster B10 via a bracket corresponding to the wedge seat 11.

[0055] The specific implementation method is as follows: the vacuum environment effect between the partition plate 503 and the buffer plate 507 gradually weakens, and when the caster B10 is connected to the inclined surface at the bottom of the wedge-shaped seat 11, the caster B10 is subjected to a lateral thrust under the action of the wedge-shaped seat 11, and the caster B10 pushes the connecting seat 501 to slide in the slide groove C802 through the slider C803, and drives the support spring B804 to undergo elastic deformation, and the stamping part adsorbed by the suction cup 701 on the connecting seat 501 and the punch 506 moves to a position. When the wheel A9 is turned sideways, it is connected with the inclined surface at the bottom of the wedge-shaped seat 11. The wheel A9 is subjected to lateral thrust, which squeezes the support spring A708 to undergo elastic deformation. The wheel A9 pushes the adjusting shaft 707. Under the push of the adjusting shaft 707, the air inlet end of the one-way valve C705 is misaligned with the adjacent air hole 704. The air inlet end of the one-way valve D706 is connected with the adjacent air hole 704. The vacuum environment in the telescopic tube disappears, and the suction force generated by the suction cup 701 on the stamping part disappears, and the stamping part performs free fall motion.

[0056] Working principle, when using:

[0057] First, place the material to be punched on the die 3, then control the hydraulic cylinder 805 to stretch, the hydraulic cylinder 805 drives the buffer assembly 5 to descend through the top cover 801 and the slider C803, before the punch 506 contacts the material to be punched on the die 3, the directional shaft connected to the bottom of the coupling seat 501 will dock with the buffer shaft 412, the coupling seat 501 presses down the buffer plate 402 through the directional shaft and the buffer shaft 412, the buffer plate 402 slides downward in the buffer cylinder 401 and squeezes the buffer piece A404 and the buffer piece B411, the transfer connecting rod 4044 of the buffer piece B411 and the transfer connecting rod 4044 of the buffer piece A404 are connected through the connecting shaft 40 5 cross rotation, at the same time, one end of the transfer link 4044 rotates around the transfer frame B4045, and pushes the slider B4046 to slide in the slide groove B413 through the transfer frame B4045, squeezing the pressure relief spring B4047 to make it elastically deformed, the other end of the transfer link 4044 rotates around the transfer frame A4042, and pushes the slider A4041 to slide in the slide groove A403 through the transfer frame A4042, squeezing the pressure relief spring A4043 to make it elastically deformed, in this process, the one-way valve A406 is opened, and the air is sucked into the space above the pressure relief plate 402 in the pressure relief cylinder 401 through the suction pipe, and the air intake per unit time of the suction pipe is small;

[0058] When the punch 506 contacts the template to be punched, the punch 506 retracts into the piston groove 502 due to the resistance of the template to be punched. At the same time, the punch 506 also drives the buffer shaft 505 to push the buffer plate 507 to move upward. During the upward movement of the buffer plate 507, the buffer spring 504 is squeezed to cause it to undergo elastic deformation.

[0059] When the buffer plate 507 slides upward in the piston groove 502, a vacuum environment is formed between the buffer plate 507 and the partition plate 503. At this time, the air inlet end of the one-way valve C705 is connected to the adjacent air hole 704 on the through pipe 703, and the air inlet end of the one-way valve D706 deviates from the adjacent air hole 704 on the through pipe 703. The vacuum effect between the buffer plate 507 and the partition plate 503 acts on the suction cup 701 through the air hole 704, the one-way valve C705 and the telescopic tube. The suction cup 701 is connected to the material to be stamped by vacuum adsorption, which is conducive to further improving the relative stability between the material to be stamped and the punch 506, and realizing the high-precision processing of the punch 506 on the material to be stamped;

[0060] After the punch 506 completes the stamping process on the material to be stamped, the hydraulic cylinder 805 is controlled to retract, and the downward pressure of the directional shaft on the pressure relief shaft 412 gradually weakens, and the pressure relief spring A4043 and the pressure relief spring B4047 begin to perform elastic reset movement. Under the joint action of the pressure relief spring B4047 and the pressure relief spring A4043, the pressure relief plate 402 will be pushed to move upward, and the pressure relief plate 402 squeezes the air that enters the pressure relief cylinder 401 through the one-way valve A406, and the one-way valve B408 opens. The air in the pressure relief cylinder 401 flows into the diverter pipe 409 through the manifold 407, the one-way valve B408 and the bridge pipe 410. After being diverted by the diverter pipe 409, the air is quickly filled into the inside of the die 3. Under the action of the air, it can have a certain demoulding effect on the stamping part.
