Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel plate stamping technology, specifically to a continuous steel sheet stamping die mechanism. Background Technology
[0002] Stamping is a processing method that uses a press and dies to apply external force to sheet metal, strip, tube and profile materials, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (steel plates) of the required shape and size.
[0003] According to patent application number 202121030054.4, a continuous stamping steel plate mold includes a base; support columns are provided at the four upper corners of the base, and a top plate is fixedly connected to the upper end of the support columns. A stamping hydraulic cylinder is provided in the middle of the upper surface of the top plate. An upper template is fixedly connected to the piston rod inside one end of the stamping hydraulic cylinder. An upper mold is provided at the lower end of the upper template. The position of the upper mold corresponds to the position of the lower mold. A lower mold base is provided on the upper side of the base. A lower mold is provided on the upper side of the lower mold base. Positioning plates are slidably connected to the two sides inside the lower mold. Positioning hydraulic cylinders are fixedly connected to the outer surfaces of the two sides of the lower mold by bolts. The piston rod at one end of the positioning hydraulic cylinder is fixedly connected to the positioning plate. A demolding mechanism is provided at one end of the lower mold base.
[0004] Although the aforementioned patent uses a positioning plate and a positioning hydraulic cylinder, the positioning plate is used for positioning during stamping, and the positioning cylinder moves the positioning plate away from the edge of the steel plate after stamping to create a gap for easy demolding, it cannot position the punching holes in the steel plate when continuously stamping long strips of steel. This results in manual measurement and positioning of the punching positions on the back of the long strip of steel plate after each stamping, which is very cumbersome and affects stamping efficiency. Therefore, we provide a continuous steel sheet stamping die mechanism to solve this problem. Utility Model Content

[0009] As a further embodiment of this utility model: the lower end of the block is provided with a circular groove corresponding to the position of the top rod, and a threaded post is installed at the upper end of the block, and the positioning post and the threaded post are screwed together.
[0010] As a further embodiment of this utility model: the limiting mechanism includes two sets of limiting plates disposed on the upper end of the base. The lower ends of the two sets of limiting plates are symmetrically connected to support rods. The lower outer part of the lower end of the support rod is equipped with a toothed plate. A gear meshes between every two toothed plates. The two gears are connected to a drive shaft. The lower end of the worktable is equipped with an mounting plate and a support seat. A servo motor is mounted on the outer side of the mounting plate. The output end of the servo motor is connected to the drive shaft. The drive shaft is rotatably connected to the support seat.
[0011] As a further embodiment of this utility model: each of the lower ends of the limiting plates is provided with an L-shaped groove, and each of the inner cavities of the L-shaped grooves is equidistantly equipped with a fixed shaft, and each of the fixed shafts is rotatably connected to a roller.
[0012] As a further embodiment of this utility model: a sliding groove is provided in the middle of the upper end of the base, and a slider is connected to the lower end of each limiting plate for sliding contact.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. The positioning mechanism uses a positioning pin to position the slots of the stamped steel plate, facilitating rapid positioning of the steel plate by the stamping assembly and the upper die for stamping operations. This effectively improves stamping efficiency. After the stamping assembly resets, the positioning mechanism drives the ejector assembly to eject the material, releasing the downward pressure generated during stamping and facilitating demolding of the long steel plate. The positioning mechanism then resets, and the operator pulls the right end of the long steel plate until the newly stamped slot at the top of the plate is positioned by the positioning pin. The positioning pin inserts into the outside of the slot, repositioning the steel plate for the next round of stamping operations. This effectively improves the positioning and stamping effect and increases stamping efficiency.
[0016] 2. The output of the servo motor drives the gear on the outer side of the drive shaft to rotate. The two sets of gear plates meshing on the outer side of the gear move in opposite directions. The gear plates then drive the limiting plate to move through the support rod until the roller in the L-shaped groove at the lower end of the limiting plate comes into contact with the steel plate. This facilitates the limiting of the steel plate, allowing for precise positioning and stamping, thus improving the stamping effect. After the stamping assembly completes the stamping, there is no need to move the limiting plate away from the steel plate. Because the roller is in contact with the steel plate, the steel plate can be pulled flexibly with minimal resistance, further improving stamping efficiency. Attached Figure Description

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5 As shown, a continuous stamping die mechanism for steel sheets includes a worktable 1, a base 2 screwed to the upper end of the worktable 1, a square groove 7 provided at the upper end of the worktable 1, a positioning mechanism 5 installed at the lower end of the worktable 1, an installation groove provided at the upper end of the base 2, a lower die 6 installed in the inner cavity of the installation groove, a through groove 10 provided at the upper end of the base 2, and a U-shaped frame 51 installed at the lower end of the worktable 1. A lifting cylinder 52 is installed at the upper end of the U-shaped frame 51, a fixing frame 54 is installed at the lower end of the base 2, and a push rod 5 is connected to the output end of the lifting cylinder 52. 3. The upper end of the push rod 53 passes through the fixing frame 54 and is connected to the fixing plate 517. The inner cavity of the through groove 10 is movably provided with a block 56. The upper end of the block 56 is provided with a positioning post 59. A spring 55 is installed between the block 56 and the fixing plate 517. The upper end of the base 2 is symmetrically provided with round holes. The inner cavity of the round holes is provided with a material ejector assembly. The material ejector assembly is connected to the push rod 53. The lower end of the block 56 is provided with a round groove 57 corresponding to the position of the push rod 53. The upper end of the block 56 is provided with a threaded post 58. The positioning post 59 and the threaded post 58 are screwed together.
[0029] The top material assembly includes a first connector 510 installed on the outside of the top rod 53. The first connector 510 is movably connected to a movable rod 513 via a pin. The movable rod 513 is movably connected to a second connector 514 via a pin. A top plate 515 is installed on the upper end of the second connector 514. Top columns 516 that are inserted into the round holes are symmetrically installed on the upper end of the top plate 515. Two connecting rods 511 are installed on the lower end of the base 2. The two connecting rods 511 are rotatably connected to the movable rod 513 via a connecting shaft 512.
[0030] Based on the punched hole and slot model of the steel plate (such as a round hole), a positioning post 59 is designed to be screwed onto the outside of the threaded post 58 at the upper end of the block 56. Different positioning blocks (such as positioning posts 59) can be designed according to different hole and slot models. Then, the hole and slot of the steel plate that has been punched once is inserted into the outside of the positioning post 59. Then, the upper die 33 is driven by the punching assembly 3 to punch the steel plate. Then, the upper die 33 and the lower die 6 complete the punching operation on the steel plate. Then, the punching assembly 3 is reset. Then, the output end of the lifting cylinder 52 drives the push rod 53 and the fixed plate 517 to move down. The fixed plate 517 drives the spring 55, the block 56 and the positioning post 59 to move down away from the inner cavity of the punched hole and slot of the steel plate, completing the first positioning punching of the steel plate. At the same time, when the push rod 53 moves down, the push rod 53 drives one end of the movable rod 513 to move down through the first connecting piece 510 and the pin. Since the movable rod is rotatably connected to the connecting rod 511 through the connecting shaft 512, the movable rod 513 then moves down. The other end then moves upward, causing the other end of the movable rod 513 to move the second connecting piece 514 and the top plate 515 upward. The top plate 515 then causes the top post 516 to pass through the round hole and lift the steel plate located at the upper end of the lower mold 6, which facilitates the release of the downward pressure brought by the stamping of the steel plate and makes it easier for the long strip of steel plate to be demolded. Then the positioning mechanism 5 resets. Subsequently, the right end of the long strip of steel plate is pulled by the operator, and the positioning post 59 moves upward due to the reset. However, when the steel plate moves, it is pressed down by the steel plate, so the positioning post 59 presses down the block 56 and the spring 55. The top rod 53 enters the inner cavity of the round groove 57 until the newly stamped hole at the upper end of the steel plate moves to the position of the positioning post 59. The spring 55 rebounds and resets, and then the spring 55 drives the block 56 and the positioning post 59 to reset. The positioning post 59 is inserted into the outside of the hole and slot to reposition the steel plate, which facilitates the next round of stamping operation. This effectively improves the positioning stamping effect and increases the stamping efficiency.
[0031] Please see Figure 3-4 , Figure 6-7As shown, a limiting mechanism 4 is provided at the upper end of the base 2, and a movable groove 8 is symmetrically provided at the upper end of the worktable 1. The lower end of the limiting mechanism 4 passes through the movable groove 8 and extends below it. The limiting mechanism 4 includes two sets of limiting plates 41 provided at the upper end of the base 2. The lower ends of the two sets of limiting plates 41 are symmetrically connected to support rods 45. Toothed plates 46 are installed on the lower outer part of the lower end of the support rods 45. A gear 47 meshes between every two toothed plates 46. The two gears 47 are connected to a drive shaft 48. The lower end of the worktable 1 is equipped with... There is a mounting plate 410 and a support base 411. A servo motor 49 is mounted on the outside of the mounting plate 410. The output end of the servo motor 49 is connected to the drive shaft 48. The drive shaft 48 is rotatably connected to the support base 411. The lower end of the limiting plate 41 is provided with an L-shaped groove 42. Fixed shafts 43 are equidistantly installed on the top of the inner cavity of the L-shaped groove 42. Rollers 44 are rotatably connected to the outside of the fixed shafts 43. A sliding groove 9 is provided in the middle of the upper end of the base 2. A slider 412 that slides with the base 41 is connected to the lower end of the limiting plate 41.
[0032] The output of the servo motor 49 drives the drive shaft 48 and the gear 47 on its outer side to rotate. The two sets of gear plates 46 meshing on the outer side of the gear 47 move in opposite directions. Then, the gear plates 46 pass through the movable groove 8 via the support rod 45 and drive the limiting plate 41 to move in opposite directions. The limiting plate 41 slides stably in the inner cavity of the slide groove 9 through the slider 412 until the roller 44 in the inner cavity of the L-shaped groove 42 at the lower end of the limiting plate 41 is in contact with the steel plate. This facilitates the limiting of the steel plate and allows for precise positioning and stamping, improving the stamping effect. After the stamping assembly 3 completes the stamping, there is no need to move the limiting plate 41 away from the steel plate. Because the roller 44 is in contact with the steel plate, the steel plate can be pulled flexibly with little resistance, which can be ignored, further improving the stamping efficiency.
[0033] Please see Figure 8 As shown, a stamping assembly 3 is installed on the upper end of the workbench 1. The stamping assembly 3 includes a top plate 31 installed on the upper end of the workbench 1. A hydraulic cylinder 32 is installed on the upper end of the top plate 31. The output end of the hydraulic cylinder 32 is screwed to an upper mold 33 corresponding to the position of the lower mold 6 through a mounting seat, so that the mounting seat and the lower mold 6 can be moved down through the output end of the hydraulic cylinder 32 to automatically punch the steel plate.
[0034] Working principle: This utility model is controlled and connected to the hydraulic cylinder 32, servo motor 49, and lifting cylinder 52 via an external control switch. In use, the slot of the steel plate, which has already been manually positioned and stamped once, is inserted into the outer side of the positioning post 59. The output of the servo motor 49 drives the drive shaft 48 and the gear 47 on its outer side to rotate. The two sets of meshing toothed plates 46 on the outer side of the gear 47 move in opposite directions. The toothed plates 46, through the support rod 45, pass through the movable groove 8, driving the limiting plate 41 to move in opposite directions. The limiting plate 41 then moves through the slider 412 in the sliding groove. The inner cavity of plate 9 slides stably until the roller 44 in the inner cavity of the L-shaped groove 42 at the lower end of the limiting plate 41 is in contact with the steel plate, which facilitates the limiting of the steel plate. Then, the upper mold 33 is driven by the stamping assembly 3 to stamp the steel plate. Subsequently, the upper mold 33 and the lower mold 6 complete the stamping operation on the steel plate. Then, the stamping assembly 3 is reset. Then, the output end of the lifting cylinder 52 drives the push rod 53 and the fixed plate 517 to move down. The fixed plate 517 drives the spring 55, the block 56 and the positioning post 59 to move down away from the inner cavity of the already stamped hole and groove of the steel plate, completing the first positioning stamping of the steel plate. At the same time, When the ejector pin 53 moves downward, it drives one end of the movable rod 513 downward through the first connecting piece 510 and the pin. Since the movable rod is rotatably connected to the connecting rod 511 via the connecting shaft 512, the other end of the movable rod 513 then moves upward. This, in turn, drives the second connecting piece 514 and the top plate 515 upward. The top plate 515 then drives the ejector pin 516 through the round hole to lift the steel plate located at the upper end of the lower mold 6, facilitating the release of downward pressure during the stamping of the steel plate and making it easier for the long, narrow steel plate to be demolded. Afterward, the positioning mechanism 5 resets, and then the process is completed by the worker... The operator pulls the right end of the long strip steel plate. Due to the contact and limiting relationship between the roller 44 and the steel plate, the steel plate can be pulled flexibly with little resistance, which can be ignored. There is no need to operate the limiting plate 41 of the limiting mechanism 4 away from the steel plate, which further improves the stamping efficiency. The steel plate continues to move until the newly stamped slot at the top of the steel plate moves to the position of the positioning post 59. The positioning post 59 is inserted into the outside of the slot to reposition the steel plate, which facilitates the next round of stamping operation. This effectively improves the positioning stamping effect and increases the stamping efficiency.
