Description

Technical Field

[0001] This utility model relates to the field of mold and die holder technology, specifically a stamping die holder. Background Technology

[0002] The stamping die set is the basic framework used to install and fix the components of the cold stamping die, ensuring that the various parts are correctly positioned, firmly and stably installed. During use, it is used to form a positioning, installation and fixed connection with the stamping equipment, so as to transmit the force and action of the stamping equipment to the working parts and complete the normal stamping forming process.

[0003] For example, CN213613721U discloses a stamping die frame structure. By rotating the handle, the rotation of the handle indirectly drives the threaded rod to rotate. The rotation of the threaded rod indirectly drives two threaded blocks to move in the same or opposite directions. The movement of the two threaded blocks indirectly drives two L-shaped fixed plates to move in the same or opposite directions via the transmission rod. This allows the operator to install and disassemble the upper die. Furthermore, the lower die of this device is connected to the connecting plate by a plug-in method, which also facilitates the replacement of the die by the operator. This makes it convenient to use dies of different specifications, expands the overall application range of the device, and facilitates its promotion.

[0004] When installing the mold onto the mold frame, the patent requires inserting the plug-in block at the bottom of the mold into the slot on the upper surface of the mold base plate to fix the mold. However, this fixing method can only fix molds of a fixed size. When the mold size changes, the plug-in block at the bottom cannot be inserted into the slot, thus limiting the installation range. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping die holder to solve the problem mentioned in the background art that the existing die holders are not convenient for installing dies of various sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die frame, comprising: a base plate and a fixing mechanism, wherein a bracket is fixedly connected to the top of the base plate, a hydraulic rod is installed on the top of the bracket, an upper die is fixed to the bottom of the hydraulic rod, and a lower die is provided at the bottom of the upper die.

[0007] A fixing mechanism is provided in the middle of the upper surface of the base plate. The fixing mechanism includes a threaded rod a that is movably connected to the base plate via a bearing. One end of the threaded rod a is fixedly connected to a bevel gear a. A bevel gear b is meshed with the outer side of the bevel gear a. Multiple sets of bevel gears c are meshed with the outer side of the bevel gear b. A threaded rod b is fixedly connected to one side of the bevel gear c. A movable plate is threadedly connected to the outer side of both the threaded rod b and the threaded rod a. Limiting mechanisms are provided on both sides of the upper surface of the base plate.

[0008] Specifically, bevel gear a meshes with bevel gear b, thereby driving bevel gear b to rotate; threaded rod a and threaded rod b are used to perform threaded transmission with the moving plate, thereby driving the moving plate to move and limiting the lower mold.

[0009] Preferably, the interior of the movable plate is movably connected to a bidirectional screw a via a bearing, and both ends of the bidirectional screw a are threadedly connected to threaded blocks.

[0010] Specifically, the bidirectional screw a is used for threaded transmission with two sets of threaded blocks, thereby driving the two sets of threaded blocks to move in relative directions.

[0011] Preferably, the outer side of the threaded block is slidably connected to the movable plate, and one side of the threaded block is movably connected to a connecting rod via a rotating shaft.

[0012] Preferably, one end of the connecting rod is movably connected to a fixed plate via a rotating shaft, and one end of the threaded rod b is movably connected to the base plate via a bearing.

[0013] Specifically, the two sets of threaded blocks drive the two sets of connecting rods to rotate, which in turn pushes the fixed plate on one side to move.

[0014] Preferably, the bottom of the bevel gear b is movably connected to the base plate via a rotating shaft, and the outer side of the movable plate is slidably connected to the base plate.

[0015] Preferably, the limiting mechanism includes a synchronous pulley a disposed on one side of the base plate, and a synchronous belt is sleeved on the outer side of the synchronous pulley a.

[0016] Preferably, a synchronous pulley b is sleeved on one side of the synchronous belt, and both the synchronous pulley b and the synchronous pulley a are fixedly connected to one side by a bidirectional screw b.

[0017] Specifically, synchronous pulley a can drive synchronous pulley b to rotate via synchronous belt, thereby driving two sets of bidirectional screws b to rotate synchronously.

[0018] Preferably, both ends of the bidirectional screw b are threadedly connected to limit plates, and the outer side of the limit plates is slidably connected to the base plate.

[0019] Specifically, the two sets of bidirectional screws b can drive the two sets of limiting plates to move relative to each other, thereby limiting the feeding.

[0020] Compared with existing technologies, the advantages of this stamping die set are:

[0021] 1. When fixing square lower dies of different sizes, this stamping die holder can achieve the following: by rotating the threaded rod a, the threaded rod a will drive the bevel gear a at its end to mesh with the bevel gear b, which in turn drives the other three sets of bevel gears c to rotate. The three sets of bevel gears c will drive the three sets of threaded rods b to rotate synchronously. When the threaded rods b and a rotate, they will both engage in threaded transmission with the moving plates, thereby driving multiple sets of moving plates and fixed plates to move closer to the lower die and fix it in the center. In this way, the above operation can facilitate the quick fixing of dies of various sizes.

[0022] 2. In order to prevent material deviation and affect the stamping effect when conveying stamping materials, the handle on one side of the synchronous wheel a is rotated to make it rotate. When synchronous wheel a rotates, it drives synchronous wheel b to rotate through the outer synchronous belt. When synchronous wheel b and synchronous wheel a rotate, they drive the double-acting screw b on one side to perform threaded transmission with the two sets of limiting plates, thereby causing the two sets of limiting plates to move closer or further apart, so as to adapt to the width of the material and prevent it from deviating during feeding. In this way, the above operation can facilitate the anti-deviation treatment of the material entering the stamping die frame. Attached Figure Description

[0029] 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.

[0030] Please see Figures 1-5 This utility model provides a technical solution: a stamping die frame, comprising: a base plate 1 and a fixing mechanism 6, a bracket 2 fixedly connected to the top of the base plate 1, a hydraulic rod 3 installed on the top of the bracket 2, an upper die 4 fixed to the bottom of the hydraulic rod 3, and a lower die 5 provided at the bottom of the upper die 4.

[0031] A fixing mechanism 6 is provided in the middle of the upper surface of the base plate 1. The fixing mechanism 6 includes a threaded rod a601 that is movably connected to the base plate 1 via a bearing. One end of the threaded rod a601 is fixedly connected to a bevel gear a602. The outer side of the bevel gear a602 is meshed with a bevel gear b603. The outer side of the bevel gear b603 is meshed with multiple sets of bevel gears c604. One side of the bevel gear c604 is fixedly connected to a threaded rod b605. The outer sides of both the threaded rod b605 and the threaded rod a601 are threadedly connected to a movable plate 606. Limiting mechanisms 7 are provided on both sides of the upper surface of the base plate 1. The interior of the movable plate 606 is movably connected to a bidirectional... The screw a607 has threaded blocks 608 at both ends. The outer side of the threaded block 608 is slidably connected to the movable plate 606. One side of the threaded block 608 is movably connected to the connecting rod 609 via a rotating shaft. One end of the connecting rod 609 is movably connected to the fixed plate 610 via a rotating shaft. One end of the threaded rod b605 is movably connected to the base plate 1 via a bearing. The bottom of the bevel gear b603 is movably connected to the base plate 1 via a rotating shaft. The outer side of the movable plate 606 is slidably connected to the base plate 1. The double-ended screw a607 and the threaded block 608 form a threaded transmission structure. The threaded block 608 and the connecting rod 609 form a rotating structure via a rotating shaft.

[0032] In practical implementation, when fixing square lower dies 5 of different sizes, the stamping die holder rotates the threaded rod a601. The threaded rod a601 drives the bevel gear a602 at its end to mesh with the bevel gear b603. In turn, the bevel gear b603 drives the other three sets of bevel gears c604 to rotate. The three sets of bevel gears c604 drive the three sets of threaded rods b605 to rotate synchronously. When the threaded rods b605 and a601 rotate, they all engage in threaded transmission with the moving plate 606, thereby driving multiple sets of moving plates 606 and fixed plates. 610 moves closer to the lower mold 5 and fixes it in the center. When it is necessary to fix the rectangular lower mold 5, the two sets of fixing plates 610 on the shorter side of the mold can be adjusted. By rotating the bidirectional screw a607 and the two sets of threaded blocks 608, the two sets of threaded blocks 608 are driven to move in opposite directions, thereby driving the connecting rod 609 to rotate. When the connecting rod 609 rotates, it can drive the fixing plate 610 to move closer to the mold and adapt to the shorter sides of the mold. In this way, the above operation can facilitate the quick fixing of molds of various sizes.

[0033] Please see Figures 1-3 The limiting mechanism 7 includes a synchronous pulley a701 disposed on one side of the base plate 1, a synchronous belt 702 sleeved on the outer side of the synchronous pulley a701; a synchronous pulley b703 sleeved on one side of the synchronous belt 702, and a bidirectional screw b704 fixedly connected to one side of both the synchronous pulley b703 and the synchronous pulley a701; both ends of the bidirectional screw b704 are threadedly connected to a limiting plate 705, the outer side of the limiting plate 705 is slidably connected to the base plate 1, and the bidirectional screw b704 and the limiting plate 705 constitute a threaded transmission structure.

[0034] In practical implementation, when conveying stamping materials, the stamping die frame prevents material deviation and affects the stamping effect. This is achieved by rotating a handle on one side of the synchronous wheel a701. The rotation of synchronous wheel a701 drives synchronous wheel b703 via the outer synchronous belt 702. Both synchronous wheel b703 and synchronous wheel a701 drive a bidirectional screw b704 on one side, ensuring synchronous rotation. The bidirectional screw b704 engages with two sets of limiting plates 705 via threaded transmission, causing the limiting plates 705 to move closer or further apart to accommodate the material width. Once adjustment is complete, rotating synchronous wheel a701 stops. At this point, the four limiting plates 705 limit the incoming material, preventing deviation during feeding. This operation facilitates anti-deviation treatment of materials entering the stamping die frame.

[0035] In summary: When using a stamping die frame, the hydraulic rod 3 is first activated to move the upper die 4 at the bottom downwards. When the upper die 4 contacts the material, it can cooperate with the lower die 5 to perform stamping processing on the material. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
