[0018] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 1 and attached Figure 2 As shown, a cold heading forming device for internal hexagonal screws includes a housing 1. A workbench 2 is fixedly installed at the lower end of the housing 1. Cold heading slots 3 are arranged at the upper end of the workbench 2. A drain pipe 4 is fixedly installed at the lower end of the workbench 2. A flexible hose 6 is arranged at the upper part of the drain pipe 4. The upper part of the flexible hose 6 is fixedly installed at the lower part of the cold heading slots 3. A U-shaped baffle 5 is fixedly installed at the upper end of the workbench 2. A lubricating oil spray box structure 7 is installed on the upper left side of the housing 1. Hydraulic cylinders 8 are fixedly installed on the left and right sides of the upper part of the housing 1.
[0019] In this implementation plan, in conjunction with the appendix Figure 2As shown, the lubricating oil spray box structure 7 includes a storage tank 71. A funnel 72 is threadedly connected to the input end of the storage tank 71. A valve 73 is threadedly connected to the output pipe of the storage tank 71. An oil outlet pipe 74 is threadedly connected to the lower part of the valve 73. A push plate 75 is fixedly installed on the lower part of the oil outlet pipe 74. A straight pipe 76 is fixedly installed on the front side of the push plate 75. The output end of the oil outlet pipe 74 is threadedly connected to the upper part of the straight pipe 76. Openings 77 are arranged in the lower part of the straight pipe 76. Cold heading plates 78 are arranged in the lower part of the push plate 75.
[0020] In this embodiment, specifically, the output rods of the two hydraulic cylinders 8 are fixedly installed at the left and right ends of the upper part of the push plate 76.
[0021] In this embodiment, specifically, the storage box 71 is fixedly installed on the upper left side of the box body 1.

[0025] Working principle
[0026] In this invention, during use, the hexagonal screws to be processed are first placed inside the cold heading groove 3. Then, the hydraulic cylinders 8 on both sides are started through the external control device. The output rods of the hydraulic cylinders 8 drive the push plate 75 to move up and down, thus processing the hexagonal screws inside the cold heading groove 3. During processing, lubricating oil is poured into the storage tank 71, and the valve 73 is opened. The lubricating oil inside the storage tank 71 is transported through the oil outlet pipe 74 and the straight pipe 76, and then discharged through the opening 77 at the bottom of the straight pipe 76. By evenly distributing the lubricating oil on the upper part of the workbench 2 and intercepting it with the U-shaped baffle 5, the lubricating oil flows into the interior of the cold heading groove 3, preventing jamming between the cold heading plate 78 and the cold heading groove 3, improving the demolding efficiency of the equipment, thereby increasing the stability of the cold heading machine, reducing cost consumption, and extending the service life of the cold heading machine.
