[0002] In modern industrial manufacturing, irregularly shaped cross-section steel is widely used in construction, machinery manufacturing, rail transportation, and other fields due to its unique mechanical properties and structural advantages. The cold-drawing process of this type of steel faces many technical challenges. Existing equipment generates a large amount of heat energy during the cold-drawing process due to friction between the steel and the equipment, which may lead to higher cold-drawing tolerances. Furthermore, the significant friction can affect product quality. Therefore, it is necessary to reduce the impact of friction on the steel to achieve higher quality cold-drawn steel sections. In view of this, this invention proposes a cold-drawing guide device suitable for irregularly shaped cross-section steel. Utility Model Content

[0030] like Figure 1-5As shown, a cold-drawing guide device suitable for irregular cross-section steel includes a housing 1 and an upper guide tube 10 and a lower guide tube 11 installed inside the housing 1. A lubricating oil tank 19 is installed on the top of the housing 1, and the lubricating oil tank 19 is connected to a pneumatic spraying device.

[0031] Furthermore, the pneumatic spraying device includes an air pump 12 installed at the bottom of the housing 1, the air pump 12 being connected to one end of an air pipe 13, and the other end of the air pipe 13 being connected to a sprayer 15.

[0032] Furthermore, the pneumatic spraying device also includes a connecting pipe 18 installed on the lubricating oil tank 19. The connecting pipe 18 is connected to the electrically controlled valve 17, the electrically controlled valve 17 is connected to one end of the oil pipe 16, and the other end of the oil pipe 16 is connected to the sprayer 15.

[0033] Furthermore, the right side of the housing 1 is provided with a feed inlet 4 and the left side is provided with a discharge outlet 22. Both the feed inlet 4 and the discharge outlet 22 are provided with guide frames, and a first guide frame 2 and a second guide frame 14 are respectively installed thereon.

[0034] Furthermore, the guide frame includes a fixed frame 201 mounted on the housing 1. Two sets of first mounting blocks 202 are mounted on the top and bottom of the fixed frame 201. The first mounting blocks 202 are rotatably connected to the vertical anti-collision kun 203. A second mounting block 204 is mounted in the middle of the first mounting block 202. A lateral anti-collision kun 205 is mounted on the second mounting block 204.

[0035] Furthermore, a sleeve 6 is provided at the top of the housing 1, the sleeve 6 is movably connected to the fixing rod 5, a fixing plate 9 is installed at the bottom of the fixing rod 5, and the upper guide 10 is rotatably connected to the fixing plate 9.

[0036] Furthermore, a fixing bolt 7 for fixing the rod 5 is detachably installed on the sleeve 6.

[0040] like Figure 1 - Figure 5As shown, the working principle of this device is as follows: First, the equipment is started. After the cold-drawn steel profile enters the equipment through the feed port 4, the motor 3 drives the lower guide tube 11 to rotate, moving the steel profile towards the discharge port 22. During the operation of the equipment, the air pump 12 delivers the generated high-pressure gas to the sprayer 15. The sprayer 15 draws the lubricating oil from the lubricating oil tank 19 and sprays it in an atomized state onto the upper guide tube 10 and the lower guide tube 11 to reduce the friction between the steel profile and the tubes. At the same time, it can also remove some of the heat generated by friction. The pressure of the upper guide tube 10 and the lower guide tube 11 on the steel profile can also straighten the bent steel profile. After straightening the cold-drawn steel profile, the steel profile is transported out from the discharge port. The guide frames installed at the feed port 4 and the discharge port 22 can prevent the material from colliding with the device when entering and exiting the equipment, causing the material to deform and improving the product quality.
