[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fasteners that hold the openings or holes of bolts or nuts. The metal is heated to about 1000 degrees Celsius and then needs to be stamped using a stamping device.

[0003] The commonly used existing stamping devices include a lower die, a hydraulic assembly and an upper die. During operation, high-temperature metal is placed on the lower die, and then the device is started so that the hydraulic assembly drives the lower die to complete the stamping operation of the wrench on the lower die. This type of stamping device is the most commonly used, but during operation, since the operator needs to continuously load and unload materials, it not only affects the processing efficiency, but also increases the labor intensity of the workers. Utility Model Content

[0007] Furthermore, the hydraulic assembly includes a hydraulic cylinder, a guide rod and a mounting plate; the hydraulic cylinder and the guide rod are vertically arranged on the mounting frame, and the end of the hydraulic cylinder and the end of the guide rod are commonly connected to the mounting plate, and an upper mold is arranged on the mounting plate.

[0008] Furthermore, a pressure bearing seat is provided on the chain conveyor frame, and the pressure bearing seat is located between the chain plates and directly below the upper mold to increase the bearing pressure of the chain plates of the chain conveyor during the stamping process.

[0009] Furthermore, the chain conveyor is also provided with a fixed frame, which is located on one side of the mounting frame and has a water storage box on it. A plurality of nozzles located above the lower mold are provided at the bottom of the water storage box. The water storage box is also provided with a water inlet pipe, which is connected to an external water source so that the external water source enters the water storage box and then sprays water mist through the nozzle. This design improves the forming efficiency of the wrench and allows the high-temperature wrench to cool down quickly after forming.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model enables the stamping and forming operation of the wrench to be carried out continuously by arranging the chain conveyor, the lower die, the hydraulic assembly, the upper die and the material receiving box. The operator only needs to complete the loading operation, and the forming and collecting operations do not require the operator's participation, which not only saves manpower labor intensity but also improves the processing efficiency of the wrench.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0017] Refer to the attached Figure 1As shown, a punching device for processing wrenches includes a chain conveyor 1, and a plurality of lower molds 2 are linearly arranged on the chain plate of the chain conveyor 1 so that the lower molds 2 move along the movement of the chain plate of the chain conveyor 1; a mounting frame 3 is provided on the frame of the chain conveyor 1, and a hydraulic component is provided on the mounting frame 3, and the hydraulic component is connected to an upper mold 5, and the upper mold 5 is located above the lower mold 2 so that after one of the lower molds 2 moves to just below the upper mold 5, the hydraulic component drives the upper mold 5 to perform a downward pressing action; a material receiving box 6 is provided below the unloading end of the chain conveyor 1 so that the formed wrenches on the lower mold 2 automatically fall into the material receiving box 6 for collection.

[0018] Specifically, refer to the attached Figure 1 As shown, the hydraulic assembly includes a hydraulic cylinder 4, a guide rod 41 and a mounting plate 42; the hydraulic cylinder 4 and the guide rod 41 are vertically arranged on the mounting frame 3, and the ends of the hydraulic cylinder 4 and the guide rod 41 are commonly connected to the mounting plate 42, and the mounting plate 42 is provided with an upper mold 5.
