[0002] Cold-formed steel, as an important metal profile, is widely used in construction, automotive, machinery manufacturing, transportation, and other fields due to its diverse cross-sectional shapes, excellent mechanical properties, and high material utilization. Among them, irregularly shaped cold-formed steel, because its unique cross-sectional structure can be designed according to specific application scenarios, can effectively meet the personalized needs of different equipment or projects for structural strength and spatial layout, leading to a continuous increase in market demand. This utility model relates to an extrusion device for irregularly shaped cold-formed steel.
[0003] Traditional extrusion equipment has a relatively fixed structure, and the position of its extrusion components is difficult to change flexibly. When dealing with irregularly shaped cold-formed steel, due to its special cross-sectional shape, traditional equipment often cannot provide a precise matching extrusion force. Utility Model Content
[0004] This utility model relates to an extrusion device for irregularly shaped cold-bent steel sections, in order to solve the technical problems mentioned in the background art.
[0005] In a first aspect, this utility model provides an extrusion device for irregularly shaped cold-formed steel sections, specifically comprising: a fixed frame; a foot mounted on the lower end of the fixed frame, a top plate bolted to the upper end of the fixed frame, a drive rod mounted on the top plate via a bearing, a bottom shell fixedly mounted on the lower end of the top plate, a partition plate bolted to the rear end of the bottom shell, a front cover mounted on the front end of the bottom shell, two arc-shaped through grooves provided on the partition plate, the bottom shell, and the front cover, a movable rod moving within the arc-shaped through grooves, a first contact wheel and a second contact wheel mounted on the movable rod, and a bottom roller and a pulley fixedly mounted on the movable rod, a vertical groove provided on the partition plate, a seat plate bolted to the partition plate, an adjusting screw mounted on the seat plate, a mating rod threaded onto the adjusting screw, the mating rod moving within the vertical groove on the partition plate, a third contact wheel mounted on the mating rod, and a connecting plate connecting the mating rod to the two movable rods.
[0006] Furthermore, welding frames are welded to both the left and right ends of the fixed frame, and a cover plate is bolted to the upper end of the welding frame. The welding frame is provided with a through groove, and movable seats that can move up and down are installed at both the front and rear ends of the welding frame. A roller is installed between the movable seats at the front and rear ends of the welding frame.
[0007] Furthermore, both of the movable seats are fixed with lead screws at their lower ends, and welding plates are welded onto the welding frame. The welding plates have through holes, and the lead screws are inserted into the through holes on the welding plates. Nuts are threaded onto the lead screws.
[0008] Furthermore, a worm gear reducer is bolted to the top plate, and a drive motor is mounted on the worm gear reducer. The output shaft of the worm gear reducer is connected to the drive rod via a coupling. Two pulleys are mounted on the drive rod. Two rotating columns are mounted on the partition plate via bearings. Two pulleys are fixedly mounted on each of the two rotating columns. A belt connects the pulleys on the rotating columns to the pulleys on the drive rod. A figure-eight belt connects the pulleys on the rotating columns to the pulleys on the movable rod.
[0009] Furthermore, top rollers are installed on both of the rotating columns.
[0010] Furthermore, a rail plate is bolted onto the bottom shell, the second contact wheel contacts the rail plate, and the first contact wheel contacts the arc-shaped through groove on the partition plate.
[0011] Furthermore, the third contact wheel contacts the vertical groove on the partition plate, and a rear cover is bolted to the rear end of the bottom shell.
[0012] This utility model provides an extrusion device for irregularly shaped cold-formed steel sections, which has the following beneficial effects: This invention uses an adjusting screw to drive a mating rod to move vertically. A connecting plate then drives two movable rods to move along an arc-shaped groove, thereby adjusting the position of the bottom roller. The top roller and bottom roller work together to form an extrusion space suitable for irregularly shaped steel, solving the problem that traditional devices cannot provide precisely matched extrusion force. Simultaneously, the first contact wheel contacts the arc-shaped groove of the partition plate, and the second contact wheel contacts the guide plate, jointly guiding the arc-shaped swing trajectory of the movable rod, ensuring stable swinging along the arc path and preventing the bottom roller from shifting during extrusion. The third contact wheel contacts the vertical groove of the partition plate, reducing friction during the vertical movement of the mating rod, minimizing processing deviations caused by component wobbling, and improving the forming accuracy of irregularly shaped cold-bent steel.
[0013] Furthermore, the movable seat of this utility model can be adjusted up and down to change the height of the idler roller through the cooperation of the lead screw and the welding plate, so as to meet the conveying needs of steel sections with different cross-sectional sizes. The position of the bottom roller can be quickly and finely adjusted by adjusting the nut on the screw. It can switch the processing of different specifications of special-shaped cold-formed steel sections without disassembling a large number of parts, thus reducing the cost of production changeover.

The partition plate 231 is provided with a vertical groove. The seat plate 232 is installed on the partition plate 231 by bolts. The seat plate 232 is installed with an adjusting screw 2322. The adjusting screw 2322 is threaded with a mating rod 2323. The mating rod 2323 moves in the vertical groove on the partition plate 231. The third contact wheel 2324 is installed on the mating rod 2323. The mating rod 2323 is connected to the two movable rods 233 by a connecting plate 2332.
[0026] In this embodiment of the utility model, welding frames 12 are welded to both the left and right ends of the fixed frame 1. A cover plate 121 is bolted to the upper end of the welding frame 12. A through groove is provided on the welding frame 12. Movable seats 122 that can move up and down are installed at the front and rear ends of the welding frame 12. A roller 123 is installed between the movable seats 122 at the front and rear ends of the welding frame 12. A lead screw 1221 is fixed to the lower end of each of the two movable seats 122. A welding plate 124 is welded to the welding frame 12. A through hole is provided on the welding plate 124. The lead screw 1221 is inserted into the through hole on the welding plate 124, and a nut is threaded onto the lead screw 1221. Its function is: rotating the nut on the lead screw 1221 can drive the movable seat 122 to move up and down along the through groove of the welding frame 12, thereby adjusting the height of the roller 123 to adapt to the conveying requirements of cold-formed steel of different sizes.
[0027] In Example 2, based on Example 1, a worm gear reducer 22 is bolted to the top plate 2. A drive motor 221 is mounted on the worm gear reducer 22. The output shaft of the worm gear reducer 22 is connected to the drive rod 21 via a coupling. Two pulleys are mounted on the drive rod 21. Two rotating columns 234 are mounted on the partition plate 231 via bearings. Two pulleys are fixedly mounted on each of the two rotating columns 234. A belt connects the pulleys on the rotating columns 234 to the pulleys on the drive rod 21. A figure-eight belt 2341 connects the pulley on the pulley and the pulley on the movable rod 233. Top rollers 2342 are installed on both rotating columns 234. Their function is: the drive motor 221 transmits power to the drive rod 21 through the worm gear reducer 22 and coupling, and then drives the two rotating columns 234 to rotate synchronously through the belt drive, so that the top rollers 2342 rotate. The figure-eight belt 2341 can drive the movable rod 233 to drive the bottom roller 2334 and the top roller 2342 to rotate in opposite directions, so as to ensure that the cold-formed steel is subjected to uniform rolling force during the extrusion process.
[0028] In Example 3, based on Examples 1 and 2, a rail plate 235 is bolted onto the bottom shell 23. The second contact wheel 2333 contacts the rail plate 235, the first contact wheel 2331 contacts the arc-shaped groove on the partition plate 231, and the third contact wheel 2324 contacts the vertical groove on the partition plate 231. A rear cover 25 is bolted onto the rear end of the bottom shell 23. Its function is as follows: the first contact wheel 2331 contacts the arc-shaped groove on the partition plate 231, and the second contact wheel 2333 contacts the rail plate 235, providing guidance and support for the movable rod 233, reducing the frictional resistance when the movable rod 233 moves, and ensuring the smoothness and stability of the position adjustment of the bottom roller 2334. The third contact wheel 2324 contacts the vertical groove on the partition plate 231, which can reduce the friction when the mating rod 2323 moves vertically.
[0029] The working principle of this embodiment is as follows: Cold-formed steel is conveyed to the extrusion area by the rollers 123 on the welding frame 12. The height of the rollers 123 can be adjusted by the screw 1221 and the nut adjusting the position of the movable seat 122. The adjusting screw 2322 drives the mating rod 2323 to move along the vertical groove of the partition 231. The mating rod 2323 drives the movable rod 233 to move along the arc-shaped through grooves on the partition 231, the bottom shell 23, and the front cover 24 via the connecting plate 2332, thereby adjusting the position of the bottom roller 2334. After the drive motor 221 starts, the power is transmitted to the drive rod 21 through the worm gear reducer 22. The drive rod 21 drives the rotating column 234 to rotate through the belt. The top roller 2342 on the rotating column 234 rotates accordingly. At the same time, the rotating column 234 drives the movable rod 233 to rotate through the figure-eight belt 2341. This causes the bottom roller 2334 on the movable rod 233 to cooperate with the top roller 2342 to form a pressing action. Finally, the top roller 2342 and the bottom roller 2334 cooperate to complete the extrusion forming of the irregular cold-formed steel.
