DETAILED DESCRIPTION
[0017] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Example 1: To address the problems of poor coordination between multi-station continuous stamping steps and the reduction in stamping accuracy caused by waste rebound, the following technical solutions are proposed: Reference Figure 1 , Figure 7-Figure 9 As shown, the multi-station stamping die set for automobile parts with an anti-damage and slag cleaning structure in this embodiment includes a column 1 and a crossbar 3 arranged on a base plate 2. The upper die base assembly is installed on the front lower end of the crossbar 3 through a chassis 4. The upper die base assembly includes a punch head 12 and an upper template 17. The lower end of the punch head 12 is connected to a pressure block 18 that is sleeved with the upper template 17. Cam buffer assemblies connected to the upper template 17 are equally installed in the punch head 12. Specifically, the upper die base assembly of the multi-station stamping die set is provided with an anti-damage buffer function by a cam buffer assembly provided in the stamping head 12, that is, when continuous stamping is performed, the stamping force between the upper die base assembly and the lower die base assembly is relieved, thereby limiting the deformation rate of the stamping part. For this purpose, the following are additionally provided: The cam buffer assembly includes a cam seat 19 rotatably disposed in the punch head 12. The upper and lower ends of the cam seat 19 are rotatably connected to an upper connecting rod 20 and a lower connecting rod 21. The upper end of the upper connecting rod 20 is elastically connected to the punch head 12, and the lower end of the lower connecting rod 21 is hinged to the pressure block 18. The cam seat 19 is an L-shaped arc structure. A fixed rod 24 connected to the punch head 12 is rotatably mounted on the outer side of the lower end of the cam seat 19. The cam seat 19 is rotatably connected to the upper connecting rod 20 and the lower connecting rod 21 through the end away from the fixed rod 24. Specifically, in the first stage of stamping: when the punch head 12 applies a stamping action downward, the upper template 17 contacts the stamping part and first produces an upward retraction action, which is transmitted to the cam seat 19 through the swing of the lower connecting rod 21. The cam seat 19 also swings through the fixed rod 24 and then continues to transmit upward to the upper connecting rod 20. The upper connecting rod 20 completes the initial mold impact reduction through the elastic buffer of the upper connection.
[0019] Reference Figure 2-Figure 6As shown, a lower die base assembly is provided below the bottom plate 2 corresponding to the upper die base assembly. The lower die base assembly includes a bottom rotary disk 5 and an upper rotary disk 6 which are arranged to rotate with each other. A die panel 7 is installed on the upper end of the upper rotary disk 6. A die cavity 8 which is evenly divided and corresponds to the upper die plate 17 is commonly defined between the upper rotary disk 6 and the die panel 7. A lower template 1 9 and a lower template 2 10 are installed in the upper rotating disk 6, which are vertically slidably connected to the mold cavity 8. A pair of lower templates 1 9 are docked to both sides of the lower template 2 10 and form the bottom surface of the mold cavity 8. A pair of spiral top rings 16 corresponding to the mold cavity 8 are embedded in the upper end of the bottom rotating disk 5. A top block 26 in contact with the spiral top ring 16 is installed at the lower end of each set of lower templates 1 9 and lower templates 2 10. Specifically, the lower die base assembly is explained in the stamping action: During the stamping process, in the loading stage, the automobile parts to be stamped are placed in the position of the die cavity 8 corresponding to the top position of the spiral top ring 16, and the upper rotary disk 6 rotates to continue to place the next automobile parts to be stamped. In this process, after the first automobile part to be stamped is placed in the first die cavity 8, driven by the continuously rotating upper rotary disk 6, the top block 26 and the spiral top ring 16 are in smooth contact as a whole, and the automobile parts to be stamped can be gradually lowered into the die cavity 8 at a uniform speed, and this cycle is repeated until they are transported to the bottom of the stamping head 12 and stop; Continuous stamping stage; Discharging stage: During discharging, after the automobile stamping parts are stamped, they rotate to the next die cavity 8 corresponding to the punch head 12 in the rotation direction. At this time, the upper rotary disk 6 continues to rotate, and drives the lower template 1 9 and the lower template 2 10 to rotate synchronously. The "bottom surface" of the die cavity 8 composed of the lower template 1 9 and the lower template 2 10 rises gradually along the spiral top ring 16, and the stamped automobile parts in the die cavity 8 rise at a uniform speed along the die cavity 8 until they stop when they are close to the die cavity 8 position during the loading stage. After stamping, all the auto parts are exposed above the die plate 7, and the "bottom surface" of the die cavity 8 formed by the lower die plate 1 9 and the lower die plate 2 10 is also flush with the surface of the die plate 7. A pneumatic purge device (not shown) is used to clean the stamping debris on the entire surface of the lower die base assembly, and a conventional robot or gripping device (not shown) is used to complete the discharge, thus completing the entire stamping process. It should be noted that the spiral top ring 16 is composed of two symmetrical structures smoothly connected together, and after the top block 26 corresponds to the spiral top ring 16, under the rotation of the upper turntable 6, the automobile parts in the mold cavity 8 are reflected in the positions of protruding from the top of the mold panel 7, immersed in the mold panel 7, and then protruding from the top of the mold panel 7, thereby performing the loading, stamping and unloading processes respectively.
[0020] An elastic block 22 is mounted on the upper end of the upper connecting rod 20, and an elastic ring 25 is mounted on the upper end of the punch head 12 corresponding to the elastic block 22. The elastic block 22 is connected to the elastic ring 25. The lower end of the lower connecting rod 21 is mounted with a hinge block 23 connected to the outer side of the pressure block 18. Specifically, the second stage of stamping is as follows. In combination with the above-mentioned initial die impact reduction action, a secondary die impact buffering action is also performed to perform a buffering compound. When the upper connecting rod 20 is subjected to the impact force, it is first received by the elastic block 22 and then released by the elastic ring 25, finally completing the secondary die impact buffering action. Therefore, by combining the two, a cam-composite elastic buffer is distributed in the entire stamping sequence, and the upper template 17 is stamped into the die cavity 8 to cooperate with the lower template 1 9 and the lower template 2 10 to complete the stamping of automobile parts, and can realize the complete anti-damage buffer of the stamping sequence of automobile stamping parts, reduce the reverse impact damage during the impact process of the stamping die, and thus reduce the deformation rate of the stamping parts.
[0021] Additional explanation is needed: when using pneumatic blowing equipment to clean stamping debris, the pneumatic blowing equipment is set parallel to the mold panel 7. When the lower template 1 9 and the lower template 2 10 complete the ejection of the automobile stamping parts after stamping and are in the discharge position, the blowing action is performed immediately to prevent the problem of stamping deformation caused by stamping debris in the subsequent continuous loading and stamping stages.
[0022] Basic principle: The present invention can realize the descent and ascent of the stamping parts through a symmetrical spiral progressive movement method, and complete the loading, stamping and discharging during the rotation process of multiple stations, so that the stamping process can be carried out continuously and collaboratively to improve the stamping efficiency, and synchronously distribute the cam-composite elastic buffer in the entire stamping process to achieve complete anti-damage buffering of the stamping process of the stamping parts, reduce the reverse impact damage during the impact process of the stamping die, and thus reduce the deformation rate of the stamping parts.
[0023] Example 2: This example further optimizes some of the structures in Example 1: Reference Figure 2 and Figure 5 As shown, an arc-shaped guide block 11 is installed between the two mold cavities 8. The arc-shaped guide block 11 is arranged with the same diameter as the lower mold plate 10, and the arc-shaped guide block 11 is connected to the lower mold plate 1 9 and the lower mold plate 2 10. A limit piece 15 is installed in the middle of the arc-shaped guide block 11 and is vertically slidably connected to the mold panel 7. Specifically, during the vertical descent and ascent of the lower template 1 9 and the lower template 2 10, displacement guidance is provided by the arc-shaped guide block 11 and the limit plate 15 to ensure that during the loading, stamping and unloading stages of the stamping parts, the stamping parts can stably descend or ascend with the stable displacement of the lower template 1 9 and the lower template 2 10 in the mold cavity 8.
[0024] The lower ends of the bottom rotary disk 5 and the upper rotary disk 6 are equipped with a driving structure for driving the two to rotate. The driving structure includes a rotating rod 13 connected to the middle part of the lower end of the upper rotary disk 6, and a motor 1 is installed at the lower end of the rotating rod 13. An inner gear ring 27 is installed on the outer side of the lower end of the bottom rotary disk 5, and a rotating gear 14 meshing with the inner gear ring 27 is installed on the lower end of the bottom rotary disk 5. A motor 2 is installed below each pair of rotating gears 14. The lower end of the outer side of the bottom rotary disk 5 corresponding to the inner gear ring 27 is connected to a bearing ring rotatably connected to the bottom plate 2, which is used for the overall support of the lower die base assembly to ensure stable rotation. Specifically, the purpose of setting the motor 1 is to provide a driving force for the rising or falling movement of the stamping part in the die cavity 8, and the purpose of setting the motor 2 is to be able to change the relative initial shape of the spiral top ring 16 and the upper rotary disk 6, and then change the initial bearing height corresponding to the stamping position when the upper rotary disk 6 rotates and the bottom rotary disk 5 is stationary, that is, change the depth of the die cavity 8; The beneficial effect is that when performing stamping operations on different automobile parts, the forming shape is actively limited. Correspondingly, when stamping automobile parts of different sizes, the loading position and the discharging position are also changed accordingly.
[0025] Structural advantages: This embodiment, combined with the first embodiment, can perform active guiding and limiting during the stamping process to ensure that the forming process of the stamping part is uniform and stable, and can also complete the active limitation of the forming shape by adjusting the depth of the die cavity 8.
[0026] Example 3: This example combines the technical contents of Example 1 and Example 2 to form a multi-station stamping method for automobile parts with an anti-damage and slag cleaning structure, referring to Figures 1-9 As shown, the following steps are included: S1: In the loading stage, the automobile part to be stamped is placed in the position of the die cavity 8 corresponding to the top position of the spiral top ring 16. After the upper rotary disk 6 rotates, the next automobile part to be stamped is placed. In this process, after the first automobile part to be stamped is placed in the first die cavity 8, driven by the continuously rotating upper rotary disk 6, the top block 26 and the spiral top ring 16 are in smooth contact as a whole, and the automobile part to be stamped can be gradually lowered into the die cavity 8 at a uniform speed. This cycle is repeated until it is transported to the bottom of the punch head 12 and stops; S2: Continuous stamping stage, when the punch head 12 applies a stamping action downward, the upper die plate 17 contacts the stamped part and first retracts upward, and the movement is transmitted to the cam seat 19 through the swing of the lower connecting rod 21. After the cam seat 19 also swings, the movement continues to be transmitted upward to the upper connecting rod 20. The upper connecting rod 20 completes the initial die impact reduction through the elastic buffer of the upper connection; When the upper connecting rod 20 is subjected to the transmission of the impact force, it is received by the elastic block 22 and then released by the elastic ring 25, and finally the secondary buffering die impact action is completed. Therefore, under the combination of the two, by forming a cam-composite elastic buffer distributed in the entire stamping step, the upper template 17 is stamped into the die cavity 8 to cooperate with the lower template 1 9 and the lower template 2 10 to complete the stamping of the automobile parts, and realize the complete anti-damage buffer of the stamping step of the automobile stamping parts, reduce the reverse impact damage during the impact process of the stamping die, and thus reduce the deformation rate of the stamped parts; S3: Discharging stage. During discharging, after the automobile stamping parts are stamped, they rotate to the next die cavity 8 corresponding to the punch head 12 in the rotation direction. At this time, the upper rotary disk 6 continues to rotate, and drives the lower template 1 9 and the lower template 2 10 to rotate synchronously. The "bottom surface" of the die cavity 8 composed of the lower template 1 9 and the lower template 2 10 rises gradually along the spiral top ring 16. At this time, the stamped automobile parts in the die cavity 8 rise at a uniform speed along the die cavity 8 until they stop when they are close to the die cavity 8 position during the loading stage. At this point, all the stamped automobile parts are exposed above the die panel 7, and the "bottom surface" of the die cavity 8 composed of the lower die plate 1 9 and the lower die plate 2 10 is also flush with the surface of the die panel 7. Pneumatic blowing equipment is used to clean the stamping debris on the surface of the entire lower die base assembly, thus completing the entire stamping process.
[0027] In summary: On the one hand, the descent and ascent of the stamping parts are achieved through a symmetrical spiral progressive movement method, and the loading, stamping and unloading are completed during the rotation process of multiple stations, so that the stamping process is carried out continuously and collaboratively to improve the stamping efficiency. In addition, the cam-composite elastic buffer is distributed throughout the entire stamping process to achieve complete anti-damage buffering of the stamping process of the stamping parts, reduce the reverse impact damage during the impact process of the stamping die, and thus reduce the deformation rate of the stamping parts; On the other hand, by actively guiding and limiting during the stamping process, it is ensured that the forming process of the stamped parts is uniform and stable, and the active limitation of the forming shape can be completed by adjusting the depth of the die cavity 8. The combination of the two ensures that the stamping process of automotive parts can be effectively protected from damage and slag removed, so as to solve the problem of reduced stamping accuracy caused by poor coordination between continuous steps of multiple stations and rebound of waste.
