Description

A stamping device for processing eyelash tubes Technical Field

[0001] This utility model relates to the technical field of eyelash tube processing equipment, and in particular to a stamping device for eyelash tube processing. Background Technology

[0002] Currently, stamping equipment for eyelash tube processing is a specialized mechanical device that uses stamping technology to process materials such as metal or plastic to manufacture eyelash tube parts. Its main function is to process raw materials into eyelash tube shapes and structures that meet design requirements through extrusion, stretching, and forming operations using stamping dies.

[0003] In the existing technology, when it is necessary to produce eyelash tubes of different specifications, shapes or sizes in small batches, such as changing the tube diameter, tube opening shape or tube body texture, the mold needs to be changed frequently. However, the mold changing process of traditional stamping equipment relies on manual operation, which requires disassembling bolts, manually aligning the mold and adjusting the accuracy. It takes a long time, usually more than ten minutes or even longer, which affects work efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a stamping device for processing eyelash tubes.

[0005] This utility model is achieved using the following technical solution: a stamping device for processing eyelash tubes, comprising a base, a bottom plate fixedly installed on the top of the base, a stamping assembly for stamping fixedly installed on the top of the bottom plate, the stamping assembly comprising four support columns fixedly installed at the four corners of the top of the bottom plate, a lower pressure plate slidably sleeved on the four support columns, an mounting plate fixedly installed at the top of the four support columns, a hydraulic actuator fixedly installed on the mounting plate, the pushing end of the hydraulic actuator fixedly installed on the top of the lower pressure plate, a lower mold provided at the top of the bottom plate, an upper mold provided at the bottom of the lower pressure plate, a fixing assembly for quick replacement of the fixing mold provided on both the bottom plate and the lower pressure plate, clamping assemblies for auxiliary positioning of the mold provided on both sides of the two fixing assemblies, a rotating groove provided on both the bottom plate and the lower pressure plate, the fixing assembly comprising a bidirectional threaded rod rotatably disposed inside the rotating groove, sliding blocks symmetrically threaded at both ends of the bidirectional threaded rod, and locking blocks fixedly installed on the opposite faces of the two sliding blocks.

[0006] With the above technical solution, when it is necessary to replace the mold, the double-threaded rod is rotated, and the double-threaded rod drives the sliding block to slide in the rotating groove, thereby separating the locking block from the fixing groove on the mold, so that the mold can be quickly disassembled; when installing a new mold, the mold is placed in the corresponding position, and the double-threaded rod is rotated to make the locking block insert into the fixing groove, thereby realizing the quick fixing of the mold and improving the efficiency of mold replacement.

[0007] As a further improvement to the above solution, both sides of the lower mold and the upper mold are provided with fixing grooves, and each fixing groove is adapted to the adjacent card block.

[0008] The above technical solution, through the matching design of the card block and the fixing groove, ensures the stability of the mold fixing, prevents the mold from shifting during the stamping process, and guarantees the stamping quality.

[0009] As a further improvement to the above solution, the clamping assembly includes a clamping plate disposed on one side of the lower mold. A sliding opening is provided on one side of the clamping plate, and connecting rods are provided on both sides of the inner cavity of the sliding opening. One end of each of the two connecting rods is fixedly installed with a sliding block, and a limiting piece is fixedly installed on the other end of each of the two connecting rods. A spring is sleeved on each of the two connecting rods, and the two ends of the two springs abut against the adjacent limiting piece and the clamping plate, respectively.

[0010] Through the above technical solution, during the process of fixing the mold by the fixing component, the sliding block moves, driving the connecting rod and the clamping plate to move. The clamping plate clamps the mold under the action of the spring, playing an auxiliary positioning role and further improving the accuracy of mold installation.

[0011] As a further improvement to the above solution, both ends of the two bidirectional threaded rods pass through adjacent rotating slots and extend to the outside of the base plate or the outside of the lower pressure plate.

[0012] With the above technical solution, both ends of the bidirectional threaded rod extend to the outside, making it convenient for operators to rotate the bidirectional threaded rod outside the equipment, thus improving the ease of operation.

[0013] As a further improvement to the above solution, ratchet wheels are fixedly installed at both ends of the two bidirectional threaded rods, a rotating block is provided on one side of each ratchet wheel, a torsion spring is provided inside each rotating block, a limiting block for restricting the rotation of the ratchet wheel is fixedly installed on the cylindrical surface of each rotating block, and each rotating block is installed on one side of the base plate or the lower pressure plate.

[0014] With the above technical solution, the operator can rotate the rotating block and use the cooperation between the limiting block and the ratchet to realize the unidirectional rotation of the bidirectional threaded rod, thereby facilitating the fixing or disassembly of the mold. At the same time, the setting of the torsion spring enables the limiting block to automatically reset, ensuring that the ratchet will not rotate on its own, thus guaranteeing the stability of the mold fixing.

[0015] As a further improvement to the above scheme, every two ratchet wheels at the same level are set in opposite directions.

[0016] With the above technical solution, the ratchets at the same level are set in opposite directions, so that the operator cannot rotate the bidirectional threaded rod. The operator can only rotate the bidirectional threaded rod by first separating the two limiting blocks from the adjacent ratchets.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention enables rapid mold replacement and precise positioning by setting up a fixing component and a clamping component, thereby improving the efficiency of mold replacement, ensuring stamping quality, and making the operation convenient and improving the practicality of the equipment.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Referring to Figures 1-3, a stamping device for processing eyelash tubes according to this embodiment includes a base 1, a base plate 2 fixedly installed on the top of the base 1, and a stamping assembly for stamping fixedly installed on the top of the base plate 2. The stamping assembly includes four support columns 301 fixedly installed at the four corners of the top of the base plate 2. A lower pressure plate 302 is slidably sleeved on the four support columns 301. An mounting plate 303 is fixedly installed on the top of the four support columns 301. A hydraulic actuator 304 is fixedly installed on the mounting plate 303. The pushing end of the hydraulic actuator 304 is fixedly installed on the top of the lower pressure plate 302. A lower mold 4 is provided on the top of the base plate 2, and an upper mold 5 is provided on the bottom of the lower pressure plate 302. Both the base plate 2 and the lower pressure plate 302 are provided with fixing components that can quickly replace and fix the molds. Clamping components for auxiliary positioning of the molds are provided on both sides of the two fixing components.

[0026] Both the base plate 2 and the lower pressure plate 302 are provided with rotating grooves 8. The fixing component includes a bidirectional threaded rod 601 rotatably disposed inside the rotating groove 8. Sliding blocks 602 are symmetrically threaded at both ends of the bidirectional threaded rod 601. A locking block 603 is fixedly installed on the opposite face of the two sliding blocks 602. Fixing grooves are provided on both sides of the lower mold 4 and the upper mold 5. Each fixing groove is adapted to the adjacent locking block 603.

[0027] When it is necessary to change the mold, rotate the bidirectional threaded rod 601. The bidirectional threaded rod 601 drives the sliding block 602 to slide in the rotating groove 8, thereby separating the locking block 603 from the fixing groove on the mold, so that the mold can be quickly disassembled. When installing a new mold, place the mold in the corresponding position, rotate the bidirectional threaded rod 601, and insert the locking block 603 into the fixing groove to achieve quick mold fixing, which improves the efficiency of mold replacement. The matching design of the locking block 603 and the fixing groove ensures the stability of mold fixing, prevents mold displacement during stamping, and ensures stamping quality.

[0028] The clamping assembly includes a clamping plate 701 disposed on one side of the lower mold 4. A sliding opening is provided on one side of the clamping plate 701, and connecting rods 702 are provided on both sides of the inner cavity of the sliding opening. One end of each connecting rod 702 is fixedly installed with a sliding block 602, and a limiting piece 703 is fixedly installed on the other end of each connecting rod 702. A spring 704 is sleeved on each connecting rod 702, and the two ends of the two springs 704 abut against the adjacent limiting piece 703 and the clamping plate 701, respectively.

[0029] During the process of fixing the mold with the fixing component, the sliding block 602 moves, driving the connecting rod 702 and the clamping plate 701 to move. The clamping plate 701 clamps the mold under the action of the spring 704, playing an auxiliary positioning role and further improving the accuracy of mold installation.

[0030] Both ends of the two bidirectional threaded rods 601 pass through adjacent rotating slots 8 and extend to the outside of the base plate 2 or the lower pressure plate 302. The extension of both ends of the bidirectional threaded rods 601 to the outside facilitates the operator to rotate the bidirectional threaded rods 601 outside the equipment, improving the convenience of operation. Both ends of the two bidirectional threaded rods 601 are fixedly installed with ratchet wheels 9. Each ratchet wheel 9 has a rotating block 10 on one side. Each rotating block 10 has a torsion spring inside. Each rotating block 10 has a limiting block 11 fixedly installed on the cylindrical surface of the rotating block 10 to restrict the rotation of the ratchet wheel 9. Each rotating block 10 is installed on one side of the base plate 2 or the lower pressure plate 302. The operator can rotate the rotating block 10 and use the cooperation between the limiting block 11 and the ratchet wheel 9 to realize the unidirectional rotation of the bidirectional threaded rods 601, thereby facilitating the fixing or disassembly of the mold. At the same time, the setting of the torsion spring allows the limiting block 11 to automatically reset, ensuring that the ratchet wheel 9 will not rotate on its own, ensuring the stability of the mold fixing. Every two ratchet wheels 9 at the same level are set in opposite directions.

[0031] The ratchet 9 at the same level is set in opposite directions, so that the operator cannot rotate the bidirectional threaded rod 601. The operator can only rotate the bidirectional threaded rod 601 by first separating the two limiting blocks 11 from the adjacent ratchet 9.

[0032] The implementation principle of a stamping device for eyelash tube processing in this application embodiment is as follows: When it is necessary to replace the lower mold 4 or the upper mold 5, rotate the rotating block 10. The rotating block 10 drives the limiting block 11 to rotate, so that the limiting block 11 is separated from the ratchet 9. Then rotate the bidirectional threaded rod 601. The bidirectional threaded rod 601 drives the sliding block 602 to slide in the rotating groove 8 through the thread transmission, so that the locking block 603 is separated from the fixed groove on the mold, and the old mold can be removed.

[0033] Place the new mold on the base plate 2 or the lower pressure plate 302 at the corresponding position. The two clamping plates 701 will be pushed by the spring 704, thus pushing the mold to the middle. Then, rotate the bidirectional threaded rod 601 in the opposite direction so that the locking block 603 is inserted into the fixing groove of the new mold. At the same time, the clamping plate 701 clamps and positions the mold. Then, release the rotating block 10. The torsion spring makes the rotating block 10 return to its original position. The limiting block 11 re-engages with the ratchet 9 to limit the rotation of the bidirectional threaded rod 601, thus completing the replacement and fixing of the mold.

[0034] The ratchet 9 at the same level is set in opposite directions, so that the operator cannot rotate the bidirectional threaded rod 601. The operator can only rotate the bidirectional threaded rod 601 by first separating the two limiting blocks 11 from the adjacent ratchet 9.

[0035] When stamping is required, the hydraulic device 304 operates, pushing the lower pressure plate 302 to slide downward along the support column 301, and the upper mold 5 and the lower mold 4 cooperate to stamp the eyelash tube material.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
