Description

Technical Field

[0001] This utility model relates to the field of hardware bending technology, specifically a multi-station hardware bending and forming composite mold. Background Technology

[0002] Metal bending is an important process in metal processing. It mainly involves applying external force to metal sheets and other metal materials to make them bend and deform at a predetermined angle. During the operation, the bending angle, length and other parameters need to be determined according to different product requirements. By using specialized bending equipment, such as bending machines, operators can precisely control the bending process to ensure that the shape and size of the final product meet the standards. Metal bending is widely used in the manufacture of various metal products, such as chassis, cabinets, furniture hardware and many other fields.

[0003] An investigation revealed that a Chinese utility model patent discloses a hardware bending device for hardware production (publication number: CN221602910U), which includes a workbench. Four support legs are fixedly connected to the bottom of the workbench, and a hardware bending device housing is fixedly connected to the top of the workbench. A mold assembly is disposed inside the hardware bending device housing, and a wiping assembly is disposed inside the hardware bending device housing. A water spray nozzle is fixedly connected to both sides of the hardware bending device housing, and a stamping assembly is fixedly connected to the top of the hardware bending device housing.

[0004] In the aforementioned patent, the connecting plate, sliding rod, and wiping sponge can clean the impurities attached to the surface of the hardware parts to be processed, which helps to extend the service life of the hardware bending device and improve the product quality after bending. However, the stamping block used for stamping and bending is fixed at the bottom of the telescopic rod. This setting may make it difficult to replace the stamping block in actual use, which results in the device being able to stamp out only a single style of hardware parts, making it difficult to meet the diversified production needs of hardware parts.

[0005] Therefore, this utility model provides a multi-station hardware bending and forming composite mold to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a multi-station hardware bending and forming composite mold, such as Figure 1 , Figure 2 and Figure 4As shown, it includes a base plate 1, a working plate 2 fixedly connected to the top of the base plate 1, a first mounting frame 3 provided on the top of the working plate 2, a stamping block 5 inserted inside the first mounting frame 3, a second mounting frame 4 fixedly connected to the top of the working plate 2, a bending die 6 inserted inside the second mounting frame 4, a first fixing mechanism provided on one side of the first mounting frame 3, and a second fixing mechanism provided on the bottom of the working plate 2.

[0027] The first fixing mechanism includes a fixing shell 23. One side of the fixing shell 23 is fixedly connected to one side of the first mounting frame 3. A first locking block 8 is slidably connected inside the fixing shell 23. A spring 7 is fixedly connected to one end of the first locking block 8. The end of the spring 7 away from the first locking block 8 is fixedly connected to the inner wall of one side of the fixing shell 23. A pull handle 9 is fixedly connected to the top of the first locking block 8. A sliding groove is provided on the fixing shell 23 for the pull handle 9 to move. The pull handle 9 extends to the outside of the fixing shell 23 through the sliding groove.

[0028] The stamping block 5 has a first latch 10 on one side that is adapted to the first latch 8. The end of the first latch 8 away from the spring 7 extends into the interior of the first mounting frame 3 and is latched into the interior of the first latch 10.

[0029] When replacing the stamping block 5, the pull handle 9 can be pulled. When the pull handle 9 moves, it will drive the first locking block 8 to move, so that the first locking block 8 will disengage from the first locking slot 10 on the stamping block 5. At this time, the stamping block 5 can be directly pulled out from the first mounting frame 3, and then a new stamping block 5 can be installed. During the process of inserting the stamping block 5 into the first mounting frame 3, its side will contact the arc surface of the first locking block 8 and squeeze the first locking block 8, causing the first locking block 8 to retract into the interior of the fixing shell 23. At the same time, the spring 7 is compressed. When the stamping block 5 is fully inserted into the interior of the first mounting frame 3, the spring 7 will release its elastic force and push the first locking block 8 into the first locking slot 10 on the stamping block 5, thereby stably fixing the stamping block 5 in the first mounting frame 3.

[0030] Furthermore, to facilitate the replacement of bending die 6 by staff, such as... Figure 1 , Figure 3 and Figure 5 As shown, the second fixing mechanism includes a support block 11, the top of which is fixedly connected to the bottom of the working plate 2. A bidirectional threaded rod 12 is rotatably connected to the support block 11. A handle 15 is fixedly connected to one end of the bidirectional threaded rod 12. A threaded block 13 is screwed onto the side surface of the bidirectional threaded rod 12. A second locking block 14 is fixedly connected to the top of the threaded block 13.

[0031] The working plate 2 has a through groove 16 for the second locking block 14 to move. The bending die 6 has a second locking slot 22 on one side that is adapted to the second locking block 14. The second locking block 14 extends to the top of the working plate 2 through the through groove 16 and is locked inside the second locking slot 22.

[0032] When changing the bending die 6, the double-threaded rod 12 can be rotated by rotating the handle 15. When the double-threaded rod 12 rotates, it will drive the two threaded blocks 13 to move relative to each other. When the threaded blocks 13 move, they will drive the second locking block 14 to move in the through groove 16. When the second locking block 14 moves out of the second locking slot 22 on the bending die 6, the bending die 6 can be directly pulled out from the second mounting frame 4. After replacing the new bending die 6, the handle 15 can be rotated in the opposite direction to make the second locking block 14 move in the through groove 16. When the second locking block 14 moves into the second locking slot 22 on the bending die 6, the bending die 6 can be stably fixed in the second mounting frame 4.

[0033] It should be noted that, in order for the stamping block 5 to move toward the bending die 6, as... Figure 1 , Figure 4 and Figure 5 As shown, a limiting rod 17 is fixedly connected to the top of the working plate 2, a top plate 18 is fixedly connected to the top of the limiting rod 17, and a slider 19 is slidably connected to the side surface of the limiting rod 17. One side of the slider 19 is fixedly connected to one side of the first mounting frame 3.

[0034] An electric push rod 20 is fixedly connected to the bottom of the top plate 18, and a traction block 21 is fixedly connected to one side of the first mounting frame 3. The movable end of the electric push rod 20 is fixedly connected to the top of the traction block 21.

[0035] After the electric push rod 20 is started, the movable end of the electric push rod 20 can drive the first mounting frame 3 to move through the traction block 21. When the first mounting frame 3 moves, it will drive the stamping block 5 inside it to move together, so that the stamping block 5 can move towards the bending die 6 for bending operation. The slider 19 provides a limiting effect for the first mounting frame 3 and improves the stability of the first mounting frame 3 when it moves.

[0036] 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.
