Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a device for straightening special-shaped steel. Background Art

[0002] Steel is a material of a certain shape, size and performance made by pressure processing of ingots, billets or steel. Most steel processing is done through pressure processing, which causes plastic deformation of the processed steel. According to the different processing temperatures of steel, it can be divided into cold processing and hot processing. Many steels need to be straightened with straightening equipment after production. Common steel pipes, steel bars, etc. can be directly straightened by a straightening machine with a multi-wheel structure. For some special-shaped steels, a straightening machine is required to perform segmented straightening processing on different positions on the surface of the steel.

[0003] The existing special-shaped steel has the following disadvantages during the straightening process: during the straightening process, manual intervention is required frequently. During the transportation of steel, manual intervention is required to continuously observe the curvature of the steel and adjust the appropriate processing position to the corresponding position of the power end of the processing machinery. The workload is large and the straightening process is cumbersome. Therefore, we propose a special-shaped steel straightening device. Utility Model Content

[0004] The main purpose of the utility model is to provide a device for straightening special-shaped steel. By means of a straightening mechanism arranged on the top of the frame, it is possible to automatically detect the steel and control the operation of the straightening components during the steel transportation process, thereby greatly reducing the amount of manual intervention and effectively solving the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A device for straightening special-shaped steel comprises a frame and a straightening mechanism. The straightening mechanism is arranged on the top of the frame. The straightening mechanism comprises a machine platform, a hydraulic cylinder, a mounting frame, a sleeve, a spring A, a plug, a spring B, a conductive sheet A and a conductive sheet B. Hydraulic cylinders for providing power for straightening the steel are installed at both upper and lower ends of the machine platform surface. Sleeves are arranged on both upper and lower sides of the mounting frame and the inside of the sleeves are movably connected with the plug via the spring A. Conductive sheets A are installed inside the sleeves via the spring B and conductive sheets B corresponding to the position of the conductive sheets A are installed at the ends of the plug.

[0007] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is arranged between the sleeve and the mounting frame, and the adjustment mechanism includes a screw hole and an external screw groove. The mounting frame is provided with screw holes at both ends and connected to the sleeve through the screw holes. The sleeve is connected to the mounting frame through the cooperation of the external screw groove and the screw hole. Before the steel straightening process is performed, the sleeve can be screwed along the screw hole to adjust the position of the end of the plug rod and the distance between the end of the plug rod, so that the end of the plug rod can fit exactly to the surface of the steel while ensuring the separation and disconnection between the conductive sheet A and the conductive sheet B. The adjustment is convenient to meet the processing requirements of steels of different specifications.

[0008] Furthermore, fixed seats are fixedly connected to both sides of the top of the frame, and guide rollers are installed on both sides of the top of the frame; when the hydraulic cylinder and the top plate are running, the fixed seats limit the steel, and the guide rollers cooperate with external conveying equipment to convey the steel.

[0009] Furthermore, the power output ends of the hydraulic cylinders are equipped with top plates for straightening the steel, and the control ends of the hydraulic cylinders are connected to the output ends of the external power supply via conductive sheets A and B; the power provided by the hydraulic cylinders drives the top plates to operate, so that the top plates process the deformed parts of the steel.

[0010] Furthermore, an external screw groove is provided on the outer periphery of the sleeve and is connected to the screw hole through the external screw groove; the position adjustment of the sleeve and the insertion rod is facilitated by the cooperation between the external screw groove and the screw hole.

[0011] Compared with the prior art, the utility model has the following beneficial effects: before the special-shaped steel straightening operation is performed, the positions of the sleeve and the plug rod are adjusted first, so that the end of the plug rod fits the surface of the standard-shaped steel of the special-shaped steel. At this time, the conductive sheet A and the conductive sheet B are in an open circuit state, and the special-shaped steel passes through the top of the frame under the action of the external conveying equipment. When the bending position of the special-shaped steel moves to the plug rod, the deformation of the steel will drive the displacement of the plug rod, causing the plug rod to drop or rise, thereby causing the conductive sheet B at the corresponding position to contact the conductive sheet A. After the hydraulic cylinder control end receives the electrical signal at the corresponding position, it controls the corresponding hydraulic cylinder to move. The force end is extended or retracted, and then the bending position of the steel is pressed and straightened through the top plate, so that the steel can be straightened during the steel transportation process, which greatly reduces the labor of manual intervention and improves the convenience of operation; the sleeve is connected to the mounting frame through the cooperation of the external screw groove and the screw hole. Before the steel is straightened, the sleeve can be twisted along the screw hole to adjust the position of the end of the plug rod and the distance between the ends of the plug rod, so that the end of the plug rod can fit exactly to the surface of the steel while ensuring the separation and disconnection between the conductive sheet A and the conductive sheet B. It is easy to adjust and can meet the processing needs of steel of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS
