Description

Technical Field

[0001] This utility model relates to the field of progressive die technology, specifically a progressive die for stamping thick steel plates. Background Technology

[0002] Progressive stamping dies (also known as step dies, step dies, or transfer dies) are cold stamping dies that use strip-shaped raw materials to complete multiple stamping processes simultaneously at several different stations on a single die during one stamping stroke of a press. After each stamping stroke, the strip moves a fixed distance once until the product is finished. This allows for the simultaneous completion of a series of processes such as automatic feeding, positioning, and forming, greatly improving work efficiency and product quality stability.

[0003] Progressive dies can complete multiple processes in a single stamping stroke, significantly improving production efficiency and reducing production time and costs. There is no human error in feeding in progressive dies, so the processing accuracy is relatively high, ensuring the precision and consistency of the products. The design of progressive dies can distribute the processes, avoiding the "minimum wall thickness" problem in single-station dies, thereby improving the overall strength and life of the die.

[0004] Existing progressive dies of this type are generally not conducive to the convenient and continuous stamping of steel plates, nor to the convenient and rapid conveying and stamping of steel plates, which affects the efficiency of progressive dies for stamping thick steel plates in rapidly conveying and stamping steel plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thick steel plate stamping progressive die, comprising a base and a lower support plate. The lower support plate is installed at the top of the base, and an upper support plate is provided outside the lower support plate. A top plate is installed at the top of the upper support plate. A feeding plate is installed on the side wall of the lower support plate, and a collecting box is provided outside the feeding plate. A first upper die is installed at the bottom of the upper support plate, a second upper die is installed on the side of the bottom of the upper support plate near the first upper die, a third upper die is installed on the side of the bottom of the upper support plate near the second upper die, and a fourth upper die is installed on the side of the bottom of the upper support plate near the third upper die. The first lower die is provided at the top of the lower support plate. A second lower mold is provided on the side of the top of the lower support plate near the first lower mold, a third lower mold is provided on the side of the top of the lower support plate near the second lower mold, and a fourth lower mold is provided on the side of the top of the lower support plate near the third lower mold. Four sets of limiting posts are installed on the top side wall of the lower support plate, and the limiting posts are slidably connected to the top plate. Support blocks are symmetrically installed on the top of the lower support plate outside the first lower mold. A connecting plate is installed on the end of each support block away from the first lower mold. A first stamped part is provided on the surface of the first lower mold at the top of the lower support plate, a second stamped part is provided on the surface of the second lower mold at the top of the lower support plate, and a third stamped part is provided on the surface of the third lower mold at the top of the lower support plate.

[0013] Preferably, the surface of each support shaft is fitted with a second roller, and the surfaces of both the first roller and the second roller are fitted with belts.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the continuous stamping die not only realizes the continuous stamping of steel plates in a convenient way, avoiding damage to the device due to excessive impact force, and improving the convenience of continuous stamping of steel plates in a thick steel plate, but also facilitates the rapid conveying and stamping of steel plates, thus improving the efficiency of rapid conveying and stamping of steel plates in a thick steel plate.

[0015] (1) When using a thick steel plate stamping progressive die, the steel plate is placed between two sets of support blocks for conveying and stamping. When it is conveyed to the top of the first lower die, the top plate, upper support plate, first upper die, second upper die, third upper die, fourth upper die, spring, and connecting plate are pressed down. Under the support of the lower support plate, the first upper die, second upper die, third upper die, and fourth upper die come into contact with the first lower die, second lower die, third lower die, and fourth lower die, respectively. Under the elastic support of the connecting plate and the spring, when the connecting plate contacts the top of the lower support plate, the top of the lower support plate forms a reaction force on the connecting plate. The connecting plate is buffered by the spring, which cancels out the reaction force and avoids damage to the device due to excessive impact force. When the first upper die presses the steel plate down to the surface of the first lower die, the excess steel plate is removed by the first lower die. The steel plate is stamped and dropped to form the first stamped product. It then continues to move forward to the surface of the second lower die. The steel plate is pressed down onto the surface of the second lower die through the second upper die. The excess steel plate is stamped and dropped off through the second lower die to form the second stamped product. It then continues to move forward to the surface of the third lower die. The steel plate is pressed down onto the surface of the third lower die through the third upper die to form the third stamped product. It then continues to move forward to the surface of the fourth lower die. The steel plate is pressed down onto the surface of the fourth lower die through the fourth upper die to form the stamped finished product. Finally, it falls into the collection box through the blanking plate for collection. This facilitates continuous stamping of steel plates and enables continuous stamping of steel plates with thick steel plates. It avoids damage to the device due to excessive impact force and improves the convenience of continuous stamping of steel plates with thick steel plates.

[0016] (2) The servo motor drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the rotating shaft and the first roller to rotate. Under the support of the support shaft and the second roller, the first roller drives the belt to move, so that the two sets of belts can quickly transport the steel plate, which facilitates the rapid transport and stamping of the steel plate. This realizes the rapid transport and stamping of the steel plate by the continuous die for thick steel plate stamping, and improves the efficiency of the continuous die for thick steel plate stamping in rapidly transporting and stamping the steel plate.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-6This utility model provides an embodiment of a thick steel plate stamping progressive die, comprising a base 1 and a lower support plate 2. The lower support plate 2 is installed at the top of the base 1, and an upper support plate 3 is provided outside the lower support plate 2. A top plate 4 is installed at the top of the upper support plate 3. A feeding plate 5 is installed on the side wall of the lower support plate 2, and a collecting box 6 is provided outside the feeding plate 5. A first upper die 7 is installed at the bottom of the upper support plate 3, a second upper die 8 is installed on the side of the bottom of the upper support plate 3 near the first upper die 7, a third upper die 9 is installed on the side of the bottom of the upper support plate 3 near the second upper die 8, and a fourth upper die 10 is installed on the side of the bottom of the upper support plate 3 near the third upper die 9. A first lower die 11 is provided at the top of the lower support plate 2, and the top of the lower support plate 2 is near the first lower die. A second lower mold 12 is provided on one side of the first lower mold 11. A third lower mold 13 is provided on the top of the lower support plate 2 near the second lower mold 12. A fourth lower mold 14 is provided on the top of the lower support plate 2 near the third lower mold 13. Four sets of limiting posts 15 are installed on the top side wall of the lower support plate 2. The limiting posts 15 are slidably connected to the top plate 4. Support blocks 16 are symmetrically installed on the top of the lower support plate 2 outside the first lower mold 11. A connecting plate 17 is installed on the end of the support block 16 away from the first lower mold 11. A first stamped product 28 is provided on the surface of the first lower mold 11 at the top of the lower support plate 2. A second stamped product 29 is provided on the surface of the second lower mold 12 at the top of the lower support plate 2. A third stamped product 30 is provided on the surface of the third lower mold 13 at the top of the lower support plate 2.

[0026] The surface of the fourth lower mold 14 at the top of the lower support plate 2 is provided with a stamped finished product 31. The outside of the upper support plate 3 is provided with a connecting plate 18. The bottom of the upper support plate 3 is provided with four sets of springs 19, and all the springs 19 are connected to the connecting plate 18.

[0027] When using a thick steel plate stamping progressive die, the steel plate is placed between two sets of support blocks 16 for conveying and stamping. When it is conveyed above the first lower die 11, the top plate 4, upper support plate 3, first upper die 7, second upper die 8, third upper die 9, fourth upper die 10, spring 19, and connecting plate 18 are pressed down. Under the support of the lower support plate 2, the first upper die 7, second upper die 8, third upper die 9, and fourth upper die 10 contact and cooperate with the first lower die 11, second lower die 12, third lower die 13, and fourth lower die 14, respectively. Under the elastic support of the connecting plate 18 and spring 19, when the connecting plate 18 contacts the top of the lower support plate 2, the top of the lower support plate 2 forms a reaction force on the connecting plate 18. The connecting plate 18, buffered by the spring 19, cancels out the reaction force, avoiding damage to the device due to excessive impact force. When the first upper die 7 presses the steel plate down onto the surface of the first lower die 11, through the first lower die... The die 11 punches off excess steel plate to form a first stamped product 28. It then moves forward to the surface of the second lower die 12, where the second upper die 8 presses the steel plate down onto the surface of the second lower die 12. The second lower die 12 punches off excess steel plate to form a second stamped product 29. It then moves forward to the surface of the third lower die 13, where the third upper die 9 presses the steel plate down onto the surface of the third lower die 13 to form a third stamped product 30. It then moves forward to the surface of the fourth lower die 14, where the fourth upper die 10 presses the steel plate down onto the surface of the fourth lower die 14 to form a stamped product 31. Finally, the product falls into the collection box 6 through the feed plate 5 for collection. This facilitates continuous stamping of steel plates, enabling continuous stamping of steel plates with a thick steel plate stamping continuous die. It avoids damage to the device due to excessive impact force and improves the convenience of continuous stamping of steel plates with a thick steel plate stamping continuous die.

[0028] Servo motors 20 are installed at the top of each connecting plate 17, and worm gears 21 are installed at the output end of each servo motor 20.

[0029] The connecting plate 17 is equipped with a rotating shaft 22 inside. The rotating shaft 22 extends through the connecting plate 17 to the outside. The upper surface of the rotating shaft 22 is equipped with a worm gear 23, and the worm 21 meshes with the worm gear 23.

[0030] The lower surface of the rotating shaft 22 is fitted with a first roller 24, and the support block 16 is movably mounted with a support shaft 25 on the side away from the connecting plate 17. The surface of the support shaft 25 is fitted with a second roller 26, and the surfaces of the first roller 24 and the second roller 26 are fitted with a belt 27.

[0031] When steel plates need to be conveyed, two sets of servo motors 20 are turned on. Supported by the connecting plate 17, the servo motors 20 drive the worm gear 21 to rotate. Under the meshing of the worm gear 21 and the worm wheel 23, the worm gear 21 drives the worm wheel 23 to rotate. The worm wheel 23 drives the rotating shaft 22 and the first roller 24 to rotate. Supported by the support shaft 25 and the second roller 26, the first roller 24 drives the belt 27 to move, so that the two sets of belts 27 can quickly convey the steel plates. This facilitates the rapid conveying and stamping of steel plates, realizing the rapid conveying and stamping of steel plates by the continuous die for thick steel plates, and improving the efficiency of the continuous die for thick steel plates in rapidly conveying and stamping steel plates.

[0032] Working principle: When using a thick steel plate stamping progressive die, the steel plate is placed between two sets of support blocks 16 for conveying and stamping. When it is conveyed above the first lower die 11, the top plate 4, upper support plate 3, first upper die 7, second upper die 8, third upper die 9, fourth upper die 10, spring 19, and connecting plate 18 are pressed down. Under the support of the lower support plate 2, the first upper die 7, second upper die 8, third upper die 9, and fourth upper die 10 are respectively connected to the first lower die 11, second lower die 12, third lower die 13, and fourth lower die 10. The mold 14 contacts and engages with the lower support plate 2. Under the elastic support of the connecting plate 18 and the spring 19, when the connecting plate 18 contacts the top of the lower support plate 2, the top of the lower support plate 2 generates a reaction force on the connecting plate 18. The connecting plate 18, buffered by the spring 19, cancels out the reaction force, preventing damage to the device due to excessive impact. When the first upper mold 7 presses the steel plate down onto the surface of the first lower mold 11, the excess steel plate is stamped off by the first lower mold 11 to form the first stamped product 28, which then continues to move forward to the second lower mold 1. The steel plate is pressed down onto the surface of the second lower die 12 by the second upper die 8, and the excess steel plate is stamped off by the second lower die 12 to form the second stamped product 29. It then moves forward to the surface of the third lower die 13, where the steel plate is pressed down onto the surface of the third lower die 13 by the third upper die 9 to form the third stamped product 30. It then moves forward to the surface of the fourth lower die 14, where the steel plate is pressed down onto the surface of the fourth lower die 14 by the fourth upper die 10 to form the stamped product 31. Finally, it falls off through the blanking plate 5. The steel plates are collected in the collection box 6, which facilitates continuous stamping of the steel plates. When the steel plates need to be conveyed, the servo motor 20 drives the worm gear 21 to rotate, the worm gear 21 drives the worm wheel 23 to rotate, and the worm wheel 23 drives the rotating shaft 22 and the first roller 24 to rotate. With the support of the support shaft 25 and the second roller 26, the first roller 24 drives the belt 27 to move, so that the two sets of belts 27 can quickly convey the steel plates, which facilitates the rapid conveying and stamping of the steel plates to complete the use of the continuous stamping die.
