Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-jamming equipment for stamping, specifically an anti-jamming guiding mechanism for metal stamping dies. Background Technology
[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) of the desired shape and size. Stamping is a production technology that uses the power of conventional or specialized stamping equipment to directly subject sheet metal to deformation forces within a die, thereby obtaining product parts with specific shapes, dimensions, and properties. Sheet metal, dies, and equipment are the three essential elements of stamping. During metal stamping, situations can occur where metal sheets get stuck in the die, requiring cleaning before processing can continue, affecting work efficiency.
[0003] Existing anti-jamming devices for metal stamping dies typically only assist in detaching metal plates stuck on the lower die. For more complex die shapes, the metal plate may become stuck on the outside of the upper die, and traditional anti-jamming structures cannot effectively detach it, limiting their application. Therefore, those skilled in the art have provided an anti-jamming guiding mechanism for metal stamping dies to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to provide a material-blocking and guiding mechanism for metal stamping dies to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A metal stamping die anti-jamming guiding mechanism includes a mounting frame, a lower die base, a lifting plate, and a limiting plate. The mounting frame has a C-shaped structure. The lower die base is bolted to the center of the bottom of the mounting frame. The lower die is bolted to the center of the lower die base. Symmetrical clearance grooves are provided on both sides of the lower die base. A hydraulic cylinder is bolted to the center of the top of the mounting frame. A connecting rod is fixedly connected to the output end of the hydraulic cylinder. A connecting block is welded to the bottom of the connecting rod. An upper die is bolted to the bottom of the connecting block. A pair of first connecting plates are welded to the top of both sides of the connecting block. A second connecting plate is vertically welded to the top of the first connecting plates in the horizontal direction. A telescopic rod is welded to the other side of the bottom of the second connecting plate. A telescopic sleeve is provided on the outer side of the telescopic rod. A spring is provided inside the telescopic sleeve. A connecting column is threaded to the bottom of the telescopic sleeve. A lifting plate is welded to the bottom of the connecting column. The lifting plate is slidably connected to the clearance groove. A pair of limiting plates are symmetrically welded to the middle of the vertical plate of the mounting frame.
[0007] As a further embodiment of this utility model: two guide grooves are symmetrically arranged at the lower part of the vertical plate of the mounting frame, and a guide plate is bolted to the tail of the lifting plate. The guide plate is slidably connected to the guide groove, and a limit block is welded to the tail of the guide plate.
[0008] As a further embodiment of this utility model: a discharge electric push rod is bolted to the middle of the vertical plate of the mounting frame, and a discharge push plate is fixedly connected to the output end of the discharge electric push rod.
[0009] As a further improvement of this utility model, multiple miniature guide rollers are rotatably connected to the bottom inner side of the limiting plate.
[0010] As a further embodiment of this utility model: the top of the base plate of the mounting frame is fixedly connected to the discharge sloping block by bolts at the side position of the lower mold base, and the cross section of the discharge sloping block is a right trapezoidal structure.
[0011] As a further improvement of this utility model: two guide rods are symmetrically welded to the top of the connecting block, and the guide rods are slidably connected to the top of the mounting frame.
[0012] As a further improvement of this utility model, two triangular removal grooves are symmetrically arranged on both sides of the lower mold mounting groove of the lower mold base.
[0013] As a further improvement of this utility model: the bottom of the telescopic rod is connected to a limit bolt by bolts, and the telescopic rod is slidably connected to the telescopic sleeve.
[0014] As a further improvement of this utility model: a long strip of magnet is glued to the bottom of the lifting plate, and the magnet is magnetically connected to the bottom of the clearance groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. In this utility model, when the stamping is completed, the hydraulic cylinder drives the connecting block to move upward. A telescopic sleeve is set between the telescopic rod and the lifting plate. As the connecting block moves upward, it drives the two lifting plates to move upward synchronously. When the metal plate is stuck in the lower die, the lifting plate lifts the metal plate stuck in the lower die to realize the metal plate unloading. When the metal plate is stuck outside the upper die, the upper die moves with the connecting block to the upper limit plate. During this process, the metal plate is unloaded by the limit plate. It has a high degree of automation, is convenient to use, and has a wide range of applications.
[0017] 2. In this utility model, when feeding material, the connecting block moves downward under the action of the hydraulic cylinder, causing the lifting plate to sink into the clearance groove. At this time, the magnet at the bottom of the lifting plate is magnetically connected to the clearance groove to prevent the lifting plate from being exposed on the surface of the lower die base, which would affect the processing operation. At this time, there is enough space between the upper die and the lower die for feeding material. When stamping operation is performed, the connecting block moves downward to allow the upper die and the lower die to cooperate. The first connecting plate on the connecting block is close to the top of the limiting plate but not in contact with it. The spring in the telescopic sleeve is compressed, and the telescopic rod is slidably connected to the telescopic sleeve. The telescopic rod is automatically adjusted without manual intervention, making it convenient to use.
[0018] 3. In this utility model, by means of the discharge electric push rod set on the back of the mounting frame, after the metal plate is unloaded, the metal plate will be clamped between the lifting plate and the limiting plate. The discharge push plate at the top of the discharge electric push rod pushes the metal plate to move. The guide roller at the bottom of the limiting plate can effectively reduce the friction between the limiting plate and the metal plate, making the discharge smoother. The metal plate finally falls onto the inclined surface of the discharge inclined block, preventing the metal plate from being damaged and affecting the product quality. Attached Figure Description

[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 Figures 1-7 In this embodiment of the utility model, the anti-jamming guiding mechanism for metal stamping dies includes a mounting frame 1, a lower die base 4, a lifting plate 12, and a limiting plate 15. The mounting frame 1 has a C-shaped structure. The lower die base 4 is bolted to the bottom center of the mounting frame 1. The lower die 5 is bolted to the center of the lower die base 4. Circumvention grooves 21 are symmetrically arranged on both sides of the lower die base 4. A hydraulic cylinder 2 is bolted to the top center of the mounting frame 1. A connecting rod 13 is fixedly connected to the output end of the hydraulic cylinder 2. A connecting block 7 is welded to the bottom of the connecting rod 13. An upper die 6 is bolted to the bottom of the connecting block 7. A pair of first connecting plates 8 are welded to the top of both sides of the connecting block 7. A second connecting plate 8 is vertically welded to the top of the first connecting plate 8 in the horizontal direction. A telescopic rod 10 is welded to the other side of the bottom of the second connecting plate 9. A telescopic sleeve 11 is provided on the outside of the telescopic rod 10. A spring 20 is provided inside the telescopic sleeve 11. A connecting post 25 is threaded to the bottom of the telescopic sleeve 11. A lifting plate 12 is welded to the bottom of the connecting post 25. The lifting plate 12 is slidably connected to the clearance groove 21. A pair of limiting plates 15 are symmetrically welded to the middle of the vertical plate of the mounting frame 1. After the stamping is completed, the lifting plate 12 moves upward as the connecting block 7 moves upward, which disengages the metal plate stuck on the lower die 5 and moves it to the bottom of the limiting plate 15. If the metal plate is stuck on the outside of the upper die 6, when the upper die 6 moves upward as the connecting block 7 moves it above the lifting plate 12, the limiting plate 15 disengages the metal plate stuck on the upper die 6. Automatic unloading is convenient to use.
[0029] Among them, two guide grooves 18 are symmetrically arranged at the lower part of the vertical plate of the mounting frame 1, and the tail of the lifting plate 12 is connected to the guide plate 26 by bolts. The guide plate 26 is slidably connected to the guide groove 18 to improve the stability of the movement of the lifting plate 12. At the same time, the top and bottom of the guide groove 18 are used to assist in limiting the rise and fall of the lifting plate 12, which is convenient to use. The tail of the guide plate 26 is welded with a limit block 27.
[0030] Among them, the middle position of the vertical plate of the mounting frame 1 is connected by bolts to the discharge electric push rod 16, and the output end of the discharge electric push rod 16 is fixedly connected to the discharge push plate 17. When discharging, the metal plate sandwiched between the lifting plate 12 and the limiting plate 15 is pushed out of the stamping working area.
[0031] Among them, multiple miniature guide rollers 22 are rotatably connected to the bottom inner side of the limiting plate 15 to reduce the friction between the limiting plate 15 and the metal plate and improve the discharge efficiency.
[0032] Among them, the top of the base plate of the mounting frame 1 is located on the side of the lower mold base 4 and is fixedly connected to the discharge inclined block 3 by bolts. The cross section of the discharge inclined block 3 is a right trapezoidal structure to prevent the metal plate after discharge from falling and causing damage.
[0033] Among them, two guide rods 14 are symmetrically welded to the top of the connecting block 7. The guide rods 14 are slidably connected to the top of the mounting frame 1 to improve the stability of the upper die 6 during stamping and improve the processing quality.
[0034] Among them, two triangular removal grooves 23 are symmetrically arranged on both sides of the mounting groove of the lower mold 5 on the lower mold base 4, which facilitates the disassembly and maintenance of the lower mold 5;
[0035] The bottom of the telescopic rod 10 is connected to a limit bolt 19 by bolts, and the telescopic rod 10 is slidably connected to the telescopic sleeve 11, which facilitates the disassembly and installation of the telescopic sleeve 11 and makes maintenance convenient.
[0036] Among them, a long strip of magnet 24 is glued to the bottom of the lifting plate 12. The magnet 24 is magnetically connected to the bottom of the relief groove 21 to ensure that the lifting plate 12 can be completely sunk into the relief groove 21 during feeding, so as to prevent affecting the stamping process.
[0037] The working principle of this utility model is as follows: Material is fed from the side of the mounting frame 1. During feeding, the lifting plate 12 sinks into the clearance groove 21 to prevent the lifting plate 12 from protruding and affecting the stamping quality. During stamping, the output end of the hydraulic cylinder 2 drives the connecting block 7 downward through the connecting rod 13, causing the upper die 6 and the lower die 5 to cooperate for stamping. At this time, the spring 20 inside the telescopic sleeve 11 is compressed, and the telescopic rod 10 is slidably connected to the telescopic sleeve 11. When stamping ends, the output end of the hydraulic cylinder 2 drives the connecting block 7 upward through the connecting rod 13, the spring 20 inside the telescopic sleeve 11 returns to its original position, and the lifting plate 12 moves upward under the action of the telescopic rod 10. When the metal plate is stuck in the lower die 5, the upward movement of the lifting plate 12 can drive the metal plate into the lower die 5. In the stripping process, when the metal plate is stuck outside the upper mold 6, the connecting block 7 drives the upper mold 6 to move above the limiting plate 15. The limiting plate 15 can strip the metal plate stuck outside the upper mold 6. The metal plate is finally stuck between the upward lifting plate 12 and the limiting plate 15. The stripping process is fully automatic, with a wide range of applications and convenient use. When the stripping is completed, the discharge electric push rod 16 drives the discharge push plate 17 to push the metal plate out between the lifting plate 12 and the limiting plate 15 and move towards the discharge inclined block 3. During this process, the guide roller 22 located at the bottom of the limiting plate 15 rotates, which can effectively reduce the friction of the metal plate sliding. It is convenient to use. The discharge inclined block 3 can effectively prevent damage to the metal plate after stripping and improve product quality.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
