[0003] There are several problems with the existing punching die reinforcement device: 1. When the punching plate is in the punched state and in contact with the part for a long time after punching the part, the long-term local force may cause inappropriate stress concentration inside the part, reducing the performance and fatigue life of the part.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The limit rod is inserted through the inside of the sliding plate and the plate in sequence until it is squeezed into the circular hole. The diameter of the circular hole should be slightly smaller than the diameter of the limit rod, so that there is a certain friction between the limit rod and the circular hole, which ultimately strengthens the connection strength between the workbench and the M-shaped block.

[0022] 2. The upper and lower inclined panels form a plate that reinforces and stabilizes the reducing part of the reducing screw, thereby ensuring that the reducing diameter is in the expected position, which is conducive to achieving accurate assembly and calibration testing requirements; at the same time, it can prevent unnecessary displacement or deformation of the reducing diameter due to factors such as force, and maintain the stability of the overall structure.

[0023] 3. The flip limit plate deflects counterclockwise through the support shaft. At this time, the limit pad fixedly connected to the top of the flip limit plate will deflect and squeeze the bottom mold to limit it, thereby limiting one end and clamping the bottom mold at the other end that is not limited.

[0024] 4. The top die slides on the sliding punch at a certain distance up and down, so the top die is still close to the top of the auto parts at this moment, and the sliding punch and the flat plate no longer exert external force to stamp the auto parts. Only the gravity of the top die squeezes the auto parts. This is to avoid the sudden disappearance of external force on the parts after stamping, which causes changes in their internal stress, resulting in abnormal deformation such as twisting and warping.

[0025] 5. The contact surfaces between the bottom inclined plate and the outer inclined plate are both inclined surfaces, and the squeezed outer inclined plate will move inward along the guide seat and squeeze the bottom mold, thereby achieving secondary reinforcement of the bottom mold during the stamping process of automotive parts.

A pad 2 is fixedly installed on the top of the support frame 1, wherein a groove is opened at the center of the top of the pad 2;

[0043] A fixing mechanism 3, which is used to clamp and reinforce the mold;

[0044] A stamping mechanism 4, which is used for stamping and forming automobile parts;

[0045] The fixing mechanism 3 is fixedly mounted on the backing plate 2 , and the punching mechanism 4 is fixedly mounted on the fixing mechanism 3 .

[0046] The fixing mechanism 3 includes a reinforcement component 31, which is fixedly connected to the groove on the top of the pad 2. The top of the pad 2 is fixedly connected to an M-shaped block 32, and the top of the M-shaped block 32 is fixedly connected to a workbench 33. The outer sides of the M-shaped block 32 and the workbench 33 are fixedly installed with fixing components 34. The top of the workbench 33 is fixedly connected to a placement plate 35, and the top of the placement plate 35 is slidably adapted to be equipped with a bottom mold 36. The outer side of the placement plate 35 is fixedly connected to a tripod 37, and the tripod 37 is fixedly connected to the top of the workbench 33.

[0047] The fixing assembly 34 includes a No. 1 nut 341, which is fixedly connected to the outside of the workbench 33. A No. 2 nut 342 is provided just below the No. 1 nut 341, and the No. 2 nut 342 is fixedly connected to the outside of the M-shaped block 32. The interiors of the No. 1 nut 341 and the No. 2 nut 342 are both threadedly connected with a reducing screw 343, and the bottom of the reducing screw 343 is threadedly connected with a movable nut 340. By passing the reducing screw 343 through the No. 1 nut 341 and the No. 2 nut 342 from top to bottom, and then simultaneously tightening the No. 1 nut 341 and the No. 2 nut The cap 342 is spirally rotated downward, wherein the cross-sectional area of ​​the upper half of the reducing screw 343 is larger than the cross-sectional area of ​​the lower half, so that the plate 345 fixedly connected to the outer side of the reducing screw 343 will eventually be squeezed and adapted to the top of the workbench 33, and the bottom of the reducing screw 343 will extend from the bottom of the pad 2. Then the movable nut 340 is used to limit and fix the bottom of the reducing screw 343, thereby playing the role of initially fixing the pad 2, the M-shaped block 32 and the workbench 33. There is a circular hole on the top of the workbench 33 The groove 344 is internally extruded to fit the limit rod 348, and the outer sides of the limit rod 348 are respectively connected with a plate 345 and a sliding piece 347. The plate 345 is fixedly connected to the outer side of the reducing screw 343. The top of the plate 345 and the outer side of the reducing screw 343 are fixedly connected with a bolt head 346. The top of the bolt head 346 is slidably connected to the sliding piece 347. The top of the reducing screw 343 is fixedly connected with a flower-shaped plate 349. The bottom of the flower-shaped plate 349 is sleeved with the limit rod 348 and is connected to the bolt head 346 by rotation. The sliding piece 347 at the top, wherein the bottom of the bolt head 346 is fixedly connected to the plate 345, and then the bottom of the sliding piece 347 is manually positioned opposite the plate 345. At this time, the limiting rod 348 is passed through the inside of the sliding piece 347 and the plate 345 in turn until it is squeezed into the circular hole groove 344. The diameter of the circular hole groove 344 is slightly smaller than the diameter of the limiting rod 348, so that there can be a certain friction between the limiting rod 348 and the circular hole groove 344, which ultimately plays a role in strengthening the connection strength between the workbench 33 and the M-shaped block 32.

[0048] like Figure 7 、 Figure 8、 Figure 9 and Figure 10 As shown, the reinforcement component 31 includes a fixing plate 312, which is fixedly connected to the bottom of the workbench 33. The outer side of the fixing plate 312 is fixedly connected to the M-shaped block 32. A semicircular hole 311 is opened on the outer side of the M-shaped block 32. The inner side of the fixing plate 312 is slidably adapted to be equipped with an upper inclined panel 313. The bottom of the upper inclined panel 313 is fixedly connected to a lower inclined panel 314. The bottom of the upper inclined panel 313 is respectively fixedly connected to a first magnet 315 and a second magnet 316. There is a The limiting plate 317 is fixedly connected to the bottom of the upper inclined panel 313. The grooved portion on the top of the pad 2 is connected to a screw rod 318 through a bearing. The outer side of the screw rod 318 is threadedly connected to an inclined support block 319. Then, the bottom mold 36 is slid inward along the top of the placement plate 35 until the inner end of the bottom mold 36 is squeezed and adapted to the tripod 37. At this time, the screw rod 318 is rotated forward by an external device or manually, so that the inclined support block 319 threadedly connected to the outer side of the screw rod 318 enters the workbench. 33 and the space between the pad 2, and in the process of the inclined support block 319 moving inward, it will hit the upper inclined panel 313 and the lower inclined panel 314 respectively, wherein the contact surfaces between the inclined support block 319 and the upper inclined panel 313 and the lower inclined panel 314 are all inclined surfaces, so the upper inclined panel 313 and the lower inclined panel 314 will be inserted into the semicircular hole 311 along the fixing plate 312, and reinforce the reducing screw 343, wherein the upper inclined panel 313 and the lower inclined panel 314 form a plate that is just right for the reducing screw The diameter reducing part of 343 is reinforced and stabilized, thereby ensuring that the diameter reducing part is in the expected position, which is conducive to achieving the requirements of precise assembly and calibration detection; at the same time, it can prevent unnecessary displacement or deformation of the diameter reducing part due to factors such as force, and maintain the stability of the overall structure. Because the punching bed is fixed, and the equipment will generate huge punching force during the punching process, the screw will be disturbed by part of the punching force. Therefore, a reasonable diameter reducing structure helps to improve the stress distribution on the screw, reduce local stress concentration, and extend the service life. The top of the inclined support block 319 is extruded and adapted to be fitted with a flip limit plate 310, the top of the flip limit plate 310 is fixedly connected to a limiting pad 3102, the center of the flip limit plate 310 is rotatably connected to a support shaft 3101, both ends of the support shaft 3101 are fixedly connected to the inside of the placement plate 35, and at the same time, the inclined support block 319 will hit the flip limit plate 310 again as it continues to move inward, causing the flip limit plate 310 to deflect counterclockwise through the support shaft 3101, and at this time, the limiting pad 3102 fixedly connected to the top of the flip limit plate 310 will deflect and squeeze and limit the bottom mold 36, thereby limiting one end and clamping and fixing the bottom mold 36 which is not limited at the other end.

[0049] like Figure 11、 Figure 12 、 Figure 13 and Figure 14 As shown, the stamping mechanism 4 includes a hydraulic cylinder 41, the bottom of the hydraulic cylinder 41 is fixedly connected to the fuselage 42, the bottom of the fuselage 42 is fixedly connected to a guide rod 43, the bottom of the guide rod 43 is fixedly connected to the pad 2, the center of the bottom of the fuselage 42 is fixedly connected to a compensation plate 44, the bottom of the compensation plate 44 is fixedly connected to an oil barrel 45, the bottom of the oil barrel 45 is fixedly connected to a flat plate 46, the bottom of the flat plate 46 is fixedly connected to a sliding punch 49, and the outer side of the sliding punch 49 is slidingly adapted with a top die 47. By starting the hydraulic cylinder 41, the guide rod 43 will move downward with the fuselage 42, and then the compensation plate 44 fixedly connected to the center of the bottom of the fuselage 42 will move downward with the oil barrel 45, wherein the oil barrel 45 is filled with lubricating oil, which plays a role in keeping the guide rod 43 lubricated, and the bottom of the oil barrel 45 is fixedly connected to the top die 47 through the flat plate 46, and finally the top die 47 will move downward and toward the bottom die 36, thereby realizing the stamping of automobile parts. In order to perform the stamping process, the two ends of the top die 47 are symmetrically connected with the stamping components 48. In addition, when the top die 47 moves downward and is subjected to the reverse force of the automobile parts, the top die 47 will move upward along the sliding punch 49 and contact the flat plate 46, wherein the sliding punch 49 will initially punch the automobile parts, and the top die 47 will subsequently stamp the automobile parts. Then, after the stamping is completed and the guide rod 43 is reset, the sliding punch 49 and the flat plate 46 will move upward. Because the top die 47 slides on the sliding punch 49 at a certain distance up and down, the top die 47 will still be tightly attached to the top of the automobile parts at this moment, and the sliding punch 49 and the flat plate 46 no longer exert external force to stamp the automobile parts. Only the gravity of the top die 47 is used to squeeze the automobile parts. This is to avoid the sudden disappearance of the external force on the stamped parts, which causes the internal stress of the parts to change, thereby causing abnormal deformation such as distortion and warping.

[0050] The stamping assembly 48 includes an extension rod 481, which is fixedly connected to the outside of the top mold 47. The outside of the extension rod 481 is fixedly connected to a bottom inclined plate 483. The end of the extension rod 481 away from the top mold 47 is fixedly connected to a compensation rod 482. The bottom of the compensation rod 482 is plugged with a sleeve rod 484. The sleeve rod 484 is fixedly connected to the top of the pad 2. The bottom of the bottom inclined plate 483 is extruded and adapted with an outer inclined plate 485. The outer side of the outer inclined plate 485 is plugged with a guide seat 486. The guide seat 486 is fixedly connected to the top of the pad 2. The inner side of the outer inclined plate 485 is fixedly connected to a spring 487. The end of the spring 487 away from the outer inclined plate 485 is fixedly connected to the guide seat 486. During the downward movement of the top mold 47, the extension rods 481 fixedly connected to its two ends will respectively move downward with the compensation rod 482 and the bottom inclined plate 483, wherein the compensation rod 482 is inserted into the sleeve rod 484, and they both play the role of limiting and stabilizing movement, and the bottom inclined plate 483 will squeeze the outer inclined plate 485 during the downward movement, wherein the contact surfaces between the bottom inclined plate 483 and the outer inclined plate 485 are both inclined surfaces, and the squeezed outer inclined plate 485 will move inward along the guide seat 486 and squeeze the bottom mold 36, thereby achieving the role of secondary reinforcement of the bottom mold 36 during the stamping process of automobile parts.

[0051] When the present invention is in use: first, the reducing screw 343 is passed through the No. 1 nut 341 and the No. 2 nut 342 from top to bottom respectively, and then the No. 1 nut 341 and the No. 2 nut 342 are spirally rotated downward at the same time, so that the plate 345 fixedly connected to the outside of the reducing screw 343 will eventually be squeezed and adapted to the top of the workbench 33, and at the same time, the movable nut 340 is manually rotated to limit and fix the bottom of the reducing screw 343, and then the sliding piece 347 connected to the top of the bolt head 346 is slid, and the bottom of the sliding piece 347 is facing the plate 345, and then the limiting rod 348 is inserted into the interior of the sliding piece 347 and the plate 345 in turn until it is squeezed into the circular hole groove 344, thereby strengthening the connection strength between the workbench 33 and the M-shaped block 32. Next, the bottom mold 36 is slid inward along the top of the placement plate 35 until the inner end of the bottom mold 36 is pressed and adapted to the tripod 37. At this time, the screw rod 318 is rotated forward by an external device or manually, so that the inclined support block 319 threaded on the outside of the screw rod 318 enters the space between the workbench 33 and the pad 2. As the inclined support block 319 moves inward, it strikes the upper inclined panel 313 and the lower inclined panel 314 respectively. The upper inclined panel 313 and the lower inclined panel 314 are then inserted into the semicircular hole 311 along the fixed plate 312, and the reducing screw 343 is reinforced again. At the same time, as the inclined support block 319 continues to move inward, it strikes the flip limit plate 310 again, causing the flip limit plate 310 to deflect counterclockwise via the support shaft 3101. At this time, the limit pad 3102 fixed to the top of the flip limit plate 310 deflects and squeezes the bottom mold 36.

[0052] By starting the hydraulic cylinder 41, the guide rod 43 will move the fuselage 42 downward, and then the compensation plate 44 fixedly connected to the bottom of the fuselage 42 will move the oil barrel 45 downward. The bottom of the oil barrel 45 is fixedly connected to the top mold 47 through the flat plate 46, so the top mold 47 will move downward and toward the bottom mold 36, thereby realizing the stamping process of the automobile parts.

[0053] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
