Description

Technical Field

[0001] This utility model relates to the field of safety shoe processing, and in particular to a safety shoe steel toe cap forming device. Background Technology

[0002] As the name suggests, a steel toe cap forming device for safety shoes is a specialized device used to manufacture the core protective component of safety shoes. Safety shoes refer to special work shoes with built-in protective devices in the toe cap to protect the toes from being crushed or squeezed. The forming device refers to a machine that processes a flat steel plate into a steel toe cap with a specific three-dimensional curved shape through a series of mechanical actions (mainly stamping, stretching, and bending).

[0003] Utility model patent CN215320448U discloses an automated forming machine for steel toe caps of safety shoes, belonging to the field of forming machines. This automated forming machine for steel toe caps of safety shoes includes a machine body. First, the inside of the oil tank is filled with lubricant. The lubricant flows through a second guide pipe in conjunction with a first guide pipe. Based on the principle of liquid level, the lubricant ultimately reaches the upper end of the first guide pipe. When the workpiece is placed on the upper end of the lower mold for forming, the downward pressure of the upper mold first drives the lower mold downward. During the downward pressure of the lower mold, an elastic airbag is squeezed. The elastic airbag, in conjunction with a waterproof and breathable membrane, squeezes out the lubricant, allowing lubrication between the workpiece and the lower mold just before forming. After forming is complete, the elastic airbag, in conjunction with a return spring, allows the lower mold to quickly return to its original position. This eliminates the need for workers to continuously spray lubricant on the lower mold; lubricant is automatically added during each forming process to prevent sticking, thus improving processing efficiency.

[0004] However, the above solution also has its shortcomings. Although lubricant can be automatically added during each molding process to prevent sticking and improve processing efficiency, it cannot be demolded quickly after stamping and requires manual assistance, which greatly reduces work efficiency. Utility Model Content

[0017] Please see Figure 1-4 This utility model provides a technical solution for a steel toe cap forming device for safety shoes: it includes a device body 1, on which two slide rails 13 are installed. Two molds 18 are slidably connected and fixedly connected to the two slide rails 13 respectively. Through the cooperation of the two slide rails 13 and the slider 19, one of the molds 18 can be driven to move horizontally. The outer wall of the rack 16 is connected to the outer wall of one of the molds 18. A motor 4 is installed on the device body 1. A support box 12 is installed on the device body 1. A guide block 15 is connected to the inner wall of the support box 12. A rack 16 is slidably connected to the inner wall of the guide block 15. The output end of the motor 4 passes through the device body 1 and the support box 12 and is connected to a gear 17. The motor 4 drives the gear 17 to rotate, which in turn drives the rack 16 to slide inside the guide block 15. The rack 16 and the gear 17 mesh. An electric push rod 3 is installed on the device body 1. The output end of the electric push rod 3 passes through the device body 1 and is connected to a push plate 14. The electric push rod 3 drives the push plate 14 to move up and down, which can push up the steel toe cap.

[0018] like Figure 1 , Figure 3As shown, a mounting bracket 7 is connected to the main body 1 of the device. Two locking plates 5 are threadedly connected to the main body 1 of the device. Each locking plate 5 is threadedly connected to the mounting bracket 7. The main body 1 of the device and the mounting bracket 7 are fixed by screws through the two locking plates 5, which further ensures the stability of the mounting bracket 7. A controller 6 is installed on the mounting bracket 7. A set of telescopic legs 2 is installed on the bottom surface of the main body 1 of the device. Two sliders 19 are slidably connected to the inner walls of the two slide rails 13. The outer walls of the two sliders 19 are connected to one of the molds 18.

[0019] like Figure 1 , Figure 4 As shown, a cylinder 9 is mounted on the mounting frame 7. An oil collection box 20 is connected to the outer wall of the output end of the cylinder 9. A mounting plate 23 is connected to the output end of the cylinder 9. Multiple sliding rods 22 are slidably connected to the inner wall of the mounting plate 23. One end of each sliding rod 22 is connected to a limit plate 21. A buffer spring 24 is sleeved on the outside of each sliding rod 22. Through the use of the buffer spring 24 and the limit plate 21, not only is the buffering force ensured during the pressing and forming of the steel bun head, but also the sliding rod 22 is prevented from sliding out of the inner wall of the mounting plate 23. The ends of the multiple sliding rods 22 away from the limit plate 21 are connected to a pressure block 25. The steel bun head can be pressed and formed by the use of the pressure block 25.

[0020] like Figure 2 As shown, an oil tank 10 is installed on the mounting bracket 7, a pump body 8 is installed on the oil tank 10, and an oil inlet pipe 11 is connected to the oil tank 10. The oil outlet end of the oil tank 10 is in contact with the outer wall of the output end of the cylinder 9. The pump body 8 can deliver the cooling lubricating oil in the oil tank 10 to the output end of the cylinder 9, ensuring lubrication and cooling.

[0021] The working principle of this utility model is as follows: First, the worker places the steel plate on the slot between the two molds 18. Then, the cylinder 9 drives the mounting plate 23 and the buffer assembly to slide downwards. The pressure block 25 contacts the steel plate, and the sliding rod 22, in conjunction with the buffer spring 24, buffers the direct impact force of the cylinder 9, preventing damage to the molds 18 and other components. Simultaneously, the pump body 8 delivers the cooling and lubricating oil from the oil tank 10 to the outer wall of the cylinder 9's output end for cooling and lubrication. To avoid overheating and damage to cylinder 9 due to prolonged operation, the pressed steel head will be stuck in the slot on mold 18. By starting motor 4, the gear 17 is driven to rotate, which in turn drives rack 16 to pull one of the molds 18 horizontally through meshing with rack 16. This causes one of the molds 18 to move from slide rail 13 using slider 19, exposing the steel head from inside mold 18 and making it detach from mold 18. Then, the electric push rod 3 and push plate 14 further push the steel head to completely detach it from the inside of mold 18.

[0022] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
