Description

Technical Field

[0001] This utility model relates to the field of cold-drawn steel rolling head device, specifically a cold-drawn steel rolling head device that is easy to position. Background Technology

[0002] A rolling head device for cold-drawn special-shaped steel production is a metal processing equipment mainly used to roll metal materials to obtain the required shape and size. Before cold drawing special-shaped steel, it is usually necessary to roll the head, that is, roll the rough end of the special-shaped steel into the thin end. The head rolling process is to obtain the required shape and size of the steel. However, in the existing head rolling process, the steel section needs to be installed, fixed and aligned with the head rolling device. A cold-drawn steel head rolling device that is easy to position is needed. Utility Model Content

[0003] The purpose of this invention is to provide a convenient positioning device for cold-drawn steel roll heads, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: it includes a base and a hydraulic lifting rod. Side rails are installed on the left and right sides of the front end of the base. The hydraulic lifting rod is installed above the front end of the base, and a platform is installed above the hydraulic lifting rod. A slide rail is installed above the platform, and a slider is slidably connected above the slide rail.

[0005] Preferably, a mounting frame is installed above the slider, and a ball bearing is installed inside the lower part of the mounting frame, allowing the steel body to slide back and forth between the ball bearing and the fixed roller.

[0006] Preferably, a fixing component is installed inside the upper part of the mounting frame, and the fixing component is threadedly connected to the mounting frame.

[0007] Preferably, the fixing assembly includes a fixing roller, guide rods and lead screws, and guide rods are installed on both sides above the fixing roller. A lead screw is rotatably connected to the upper center of the fixing roller. The lead screw is threadedly connected to the mounting frame, and the guide rods are slidably connected to the mounting frame.

[0008] Preferably, a steel profile body is installed below the fixed roller, and the steel profile body and the fixed roller are slidably connected.

[0009] Preferably, a roller frame is installed above the rear end of the base, and the roller frame is welded to the base.

[0010] Preferably, a lower roll is installed on the inner side of the roll frame, and the lower roll is rotatably connected to the roll frame. One end of the steel body extends between the upper roll and the lower roll, and multiple grooves of different specifications are formed between the upper roll and the lower roll.

[0011] Preferably, an upper roll is installed above the lower roll, and a hydraulic telescopic rod is installed above the upper roll. The hydraulic telescopic rod applies a certain pressure to the upper roll through the roll frame, thereby rolling the steel body into a suitable thickness.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The steel profile body passes through the mounting frame, and the rotating screw drives the fixed roller below the guide rod to press down onto the steel profile body. The steel profile body can slide back and forth between the ball bearings and the fixed roller. One end of the steel profile body extends between the upper and lower rollers. The hydraulic telescopic rod applies a certain pressure to the upper roller through the roller frame, thereby rolling the steel profile body into a suitable thickness. When a finer thickness is required, different sized grooves between the upper and lower rollers can be used one by one. The hydraulic lifting rod extends and retracts, causing the platform to slide up and down inside the side rail. The slider slides on the slide rail, thereby causing the mounting frame to move left and right on the platform. The steel profile body moves with the mounting frame until the central axis of the steel profile body coincides with the central axis of the groove between the upper and lower rollers, which facilitates the installation and positioning of steel profile bodies of different specifications.

[0013] This utility model proposes a convenient positioning device for cold-drawn steel rolling heads. Attached Figure Description

A steel body 14 is installed below the fixed roller 1201, and the steel body 14 is slidably connected to the fixed roller 1201. The extension and retraction of the hydraulic lifting rod 8 drives the platform 7 to slide up and down inside the side rails 6, and the slider 10 slides on the slide rail 9, thereby driving the mounting frame 11 to move left and right on the platform 7. The steel body 14 moves with the mounting frame 11 until the central axis of the steel body 14 coincides with the central axis of the groove between the upper roller 4 and the lower roller 5, which facilitates the installation and positioning of steel bodies 14 of different specifications.

The steel body 14 can slide back and forth between the ball bearing 13 and the fixed roller 1201. One end of the steel body 14 extends between the upper roller 4 and the lower roller 5. The hydraulic telescopic rod 3 applies a certain pressure to the upper roller 4 through the roller frame 2, thereby rolling the steel body 14 into a suitable thickness. When a finer state is required, different sized grooves between the upper roller 4 and the lower roller 5 can be used one by one.

[0023] In actual use, the steel body 14 is passed through the mounting frame 11. The rotating screw 1203 drives the fixed roller 1201 below the guide rod 1202 to press down onto the steel body 14. The steel body 14 can slide back and forth between the ball bearing 13 and the fixed roller 1201. One end of the steel body 14 extends between the upper roller 4 and the lower roller 5. The hydraulic telescopic rod 3 applies a certain pressure to the upper roller 4 through the roller frame 2, thereby rolling the steel body 14 into a suitable thickness. When a finer thickness is required, different sized grooves between the upper roller 4 and the lower roller 5 can be used one by one. The hydraulic lifting rod 8 extends and retracts, driving the platform 7 to slide up and down inside the side rail 6. The slider 10 slides on the slide rail 9, thereby driving the mounting frame 11 to move left and right on the platform 7.
