Description

Technical Field

[0001] This utility model relates to the field of safety shoe manufacturing technology, and more specifically to a shaping machine for aluminum alloy safety shoe toes. Background Technology

[0002] Safety shoes are a general term for safety shoes and protective shoes. They generally refer to footwear worn in different work environments to protect the feet and legs from foreseeable injuries, including those caused by heavy objects, sharp objects, electric shocks, and chemicals. The strength of the toe cap determines the protective performance of the safety shoe; therefore, the performance of the toe cap is particularly important.

[0003] Traditional safety shoes are mostly made of carbon fiber or fiberglass plastic toe caps. These safety shoes are relatively lightweight and easy for the wearer to walk in. However, these safety shoes have low compressive strength and cannot withstand the impact of falling heavy objects. Therefore, aluminum alloy toe caps are used instead of traditional carbon fiber or fiberglass plastic toe caps. Although they are heavier, they provide sufficient protection for the wearer.

[0004] The production process of aluminum alloy safety shoe toes requires first stamping aluminum alloy sheets into the shape of a shoe toe before the safety shoes are produced. Aluminum alloy safety shoe toes are mostly produced using a forming machine. When producing safety shoe toes, different stamping dies need to be changed when the shoe size is different. Therefore, the production of safety shoe toes requires frequent die changes, which reduces the production efficiency of safety shoe toes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a shaping machine for aluminum alloy safety shoe toes, which can produce the same type of safety shoe toes of different shoe sizes without changing the mold, thereby improving the production efficiency of safety shoe toes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0007] A shaping machine for aluminum alloy safety shoe toes includes an operating table with a lower mold on it. Above the lower mold, via a lifting mechanism, is an upper mold corresponding to the lower mold. The lower mold has a groove corresponding to the safety shoe toe, and the upper mold has a protrusion corresponding to the groove. The lifting mechanism includes a support vertically mounted on the operating table, a crossbeam on the support, and a lifting cylinder above the crossbeam. The extension rod of the lifting cylinder passes through the end of the crossbeam and is connected to a lifting plate. The upper mold is positioned on the bottom surface of the lifting plate.

The lower and upper molds are respectively mounted on the operating table and the lifting plate via quick-release mechanisms. A PLC controller is mounted on the operating table, and the output of the PLC controller is connected to the input of the lifting cylinder.

[0008] To further optimize the technical solution, the lower die adjustment mechanism includes two transverse moving slots opened on the lower die moving block. A lower die bidirectional lead screw is provided in one of the moving slots. A lower die slider that moves with the lower die bidirectional lead screw and a guide block that slides along the other moving slot are provided at the bottom of the lower die. A lower die knob for rotating the lower die bidirectional lead screw is provided on the side end of the lower die moving block.

[0009] To further optimize the technical solution, the upper mold adjustment mechanism includes two transverse moving slots opened on the upper mold moving block.

The ends of the connecting rods are hinged to positioning blocks that extend into the locking grooves of the mounting blocks for fixing the mounting blocks. The middle part of the connecting rod is fixedly connected to the inside of the mold mounting slot through a hinged connecting plate. The input end of the bidirectional electric cylinder is connected to the output end of the PLC controller.

[0011] To further optimize the technical solution, a heating plate for heating the lower mold is provided inside the lower mold, and a temperature sensor for collecting the temperature of the lower mold is provided inside the lower mold. The output terminal of the temperature sensor is connected to the input terminal of the PLC controller, and the output terminal of the PLC controller is connected to the input terminal of the heating plate.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Aluminum alloy safety shoe toe shaping machine for safety shoes, combined with Figures 1 to 4 As shown, the machine includes an operating table 1, on which a lower mold 2 is provided. Above the lower mold 2, an upper mold 3 corresponding to the lower mold 2 is provided via a lifting mechanism. The lower mold 2 has a groove corresponding to the safety shoe toe, and the upper mold has a protrusion structure corresponding to the groove. The operating table 1 is equipped with a PLC controller 12 to control the operation of the shaping machine.

[0023] The lifting mechanism includes a support 51 vertically mounted on the operating table 1, a crossbeam 52 mounted on the support 51, a lifting cylinder 54 mounted above the crossbeam 52, a lifting plate 53 mounted at the end of the extension rod of the lifting cylinder passing through the crossbeam, and an upper mold 3 mounted on the bottom surface of the lifting plate 53. The lifting cylinder drives the lifting plate to move up and down, thereby stamping and shaping the aluminum alloy safety shoe toe placed on the upper mold and the lower mold. The input end of the lifting cylinder is connected to the output end of the PLC controller.

[0024] A guide rod 55 is provided between the operating platform 1 and the crossbeam 53. The guide rod passes through the lifting plate 53 and is used to guide the lifting plate.

[0025] Both the lower mold 2 and the upper mold 3 are composed of two corresponding mold pieces spliced ​​together. The lower mold 2 is set on the operating table 1 through the lower mold moving block 23, and the upper mold 3 is set on the lifting plate 53 through the upper mold moving block 32. The lower mold moving block and the upper mold moving block are respectively equipped with an upper mold adjustment mechanism and a lower mold adjustment mechanism, which are used to adjust the lateral dimension between the two molds.

[0026] The upper mold adjustment mechanism includes two transverse moving grooves 210 that are laterally opened on the lower mold moving block 23. One of the moving grooves 210 is provided with a lower mold bidirectional lead screw 24. The bottom of the lower mold 2 is provided with a lower mold slider 25 that moves with the lower mold bidirectional lead screw and a guide block that slides along the other moving groove 210. The side end of the lower mold moving block 23 is provided with a lower mold knob 26, which is used to rotate the lower mold bidirectional lead screw. When stamping and shaping safety shoe toes of different sizes, the distance between the two lower molds is adjusted by rotating the lower mold knob. The adjustment of different sizes of safety shoe toes is achieved by adjusting the overall width of the lower mold.

[0027] The lower mold adjustment mechanism includes two transverse moving slots horizontally opened on the upper mold moving block 32. One of the moving slots houses the upper mold bidirectional lead screw 33. The top of the upper mold 32 is equipped with an upper mold slider that moves with the bidirectional lead screw and a guide block that slides along the other moving slot. An upper mold knob 34 is located on the side of the upper mold moving block 32 to rotate the bidirectional lead screw. When stamping and shaping safety shoe toes of different sizes, the distance between the two upper molds is adjusted by rotating the upper mold knob. Adjusting the overall width of the upper mold achieves the adjustment of different sizes of safety shoe toes. In this application, corresponding dimensions can be marked on the lower and upper mold moving blocks. During adjustment, the distance between the molds can be adjusted according to the marked dimensions to ensure consistency of different sizes of safety shoe toes. The upper and lower knobs can also be marked, with each mark corresponding to a different size, thus ensuring product consistency.

[0028] To facilitate impact shaping of different types of safety shoe toes, the upper mold and lower mold are respectively set on the operating table 1 and the lifting plate 53 via quick-release mechanism 4.

[0029] The quick-release mechanism 4 includes a mold mounting slot 11 opened on the operating table 1 and the lifting plate 53. The lower mold moving block 23 is set in the mold mounting slot on the operating table through the lower mold mounting block 21, and the upper mold moving block 32 is set in the mold mounting slot on the lifting plate through the upper mold mounting block 31. The side ends of the lower mold mounting block 21 and the upper mold mounting block 31 are provided with locking grooves 29. The mold mounting slot is equipped with a bidirectional electric cylinder 41. The ends of the telescopic rods on both sides of the bidirectional electric cylinder are hinged with connecting rods 42. The ends of the connecting rods 42 are hinged with positioning blocks 43 that extend into the locking grooves of the mounting blocks for fixing the mounting blocks. The middle part of the connecting rods 42 is fixedly connected to the inside of the mold mounting slot through a hinged connecting plate 44. The input end of the bidirectional electric cylinder is connected to the output end of the PLC controller. When installing the mold, push the mold mounting block into the mold mounting slot. Once in place, the double-acting electric cylinder pushes the telescopic rod outward, causing the bottom end of the connecting rod to move outward. Under the action of the connecting plate, the top end of the connecting rod moves inward, pushing the positioning block inward and extending into the positioning slot of the mounting block to fix the mold. When disassembling the mold, the double-acting electric cylinder pulls the connecting rod inward. Under the action of the connecting plate, the top end of the connecting rod moves outward, causing the positioning block to move outward, releasing the positioning slot of the mounting block. At this point, the mold can be removed from the mold mounting slot.

[0030] The lower mold 2 is equipped with a heating plate 7 to heat the lower mold. A temperature sensor 28 is also installed inside the lower mold to collect the temperature of the lower mold. The output of the temperature sensor is connected to the input of the PLC controller, and the output of the PLC controller is connected to the input of the heating plate. By heating the lower mold, the aluminum alloy shoe toe is heated to reduce the rebound rate of the aluminum alloy shoe toe and ensure the shaping effect.

[0031] The lower mold 2 has a connection terminal on its side for connecting the heating plate 27 and the temperature sensor 28. The operating table 1 has a connection terminal for connecting the PLC controller. The connection terminals are connected by wires 22. The heating plate and the temperature sensor are connected to the PLC controller by wires, which facilitates the disassembly and assembly of the lower mold.

[0032] In operation, this invention adjusts the dimensions of the upper and lower molds using a knob according to the size of the safety shoe toe. After adjustment, the aluminum alloy shoe toe is placed in the groove of the lower mold. A heating plate heats the lower mold, and a lifting cylinder pushes the upper mold downwards to stamp and shape the aluminum alloy shoe toe within the lower mold. After a set time, the shaped aluminum alloy shoe toe is obtained. This invention allows for quick mold replacement via a quick-release structure, adapting to the shaping of safety shoe toes with different specifications.
