Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to an electromagnetic straightening plate for a bar cooling bed. Background Art

[0002] During the bar preparation process, after the rolled piece is rolled out from the K1 finished hole, it is transported through the water piercer, the double-length flying shear, the rapid guide section conveyor roller in front of the cooling bed, and the rapid conveyor roller in the cooling bed section, and then thrown to the straightening plate of the steel cooling bed through the steel loading device. Among them, the steel loading device is one of the important equipment of the bar production line. Its main function is to quickly brake the finished rebar from the conveyor roller through the skirt plate, friction plate and straightening plate to make the finished rebar stationary. During the braking process, since the rebar slides in the entrance section of the straightening plate, it relies entirely on the friction generated by its own weight for braking. Therefore, when the actual rolling speed exceeds the design rolling speed, the finished rebar will rush out of the cooling bed, causing product scrap and restricting rolling capacity.

[0003] In view of this, it is necessary to design an electromagnetic straightening plate for a bar cooling bed to solve the above problems. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0027] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0028] See also Figure 1 As shown, the utility model provides an electromagnetic straightening plate for a bar cooling bed, comprising:

[0029] Straightening plate body 10;

[0030] An electromagnetic device, disposed below the inlet section of the straightening plate body 10, for increasing the force exerted by the steel material 50 on the inlet section of the straightening plate;

[0031] A cooling device is used to reduce the temperature of the electromagnetic device.

[0032] Specifically, the electromagnetic device includes an electromagnet 21 and a control component for controlling the conversion of the electromagnet 21 between a magnetic state and a non-magnetic state, so that when the control component is in a magnetic state, the steel 50 located on the working surface 11 of the entrance section of the straightening plate body 10 is subjected to a certain amount of suction, so that the positive pressure of the steel 50 acting on the working surface 11 increases, thereby increasing the friction between the steel 50 and the working surface 11, braking the steel 50, reducing the sliding distance of the steel 50, and preventing the steel 50 from rushing out of the cooling bed.

[0033] Specifically, the top of the electromagnet 21 is in close contact with the bottom surface of the entrance section of the straightening plate body 10 .

[0034] Several electromagnetic devices are provided. For example, 3-6 electromagnetic devices are spaced perpendicular to the direction of movement of the steel 50 below the inlet section of the straightening plate body 10. The suction force exerted by the electromagnetic devices on the steel 50 can be adjusted based on the sliding distance of the steel 50 on the working surface 11. In actual use, the electromagnetic devices can exert a certain suction force on the steel 50 to prevent the steel 50 from rushing out of the cooling bed.

[0035] A power interface 22 is provided at the bottom of the electromagnetic device.

[0036] When the electromagnetic device is used to decelerate the steel material 50 , in addition to controlling the magnitude of the electromagnetic force of the electromagnetic device, the sliding distance of the steel material 50 can also be adjusted by controlling the action time of the electromagnetic device.

[0037] Specifically, such as Figure 2As shown, the cooling device includes cooling water pipes 30 wound around the electromagnet 21. The cooling water pipes 30 are arranged in a plurality of turns along the vertical direction, and the spacing between adjacent cooling water pipes 30 gradually decreases as they move upward, thereby effectively cooling the upper portion of the electromagnet 21. The provision of cooling water pipes 30 can cool the electromagnet 21 during operation, preventing the temperature of the electromagnet 21 from rising due to the high temperature of the steel 50, which could affect the magnetic force and stability of the electromagnetic device.

[0038] The water inlet 31 and the water outlet 32 of the cooling water pipe 30 are located at the lower part of the electromagnetic device.

[0039] Specifically, friction plates 40 are installed on one side and on the working surface 11 of the inlet section of the straightening plate body 10. The friction plates 40 are made of highly wear-resistant materials, such as high-manganese steel or high-chromium cast iron. The friction plates 40 increase the friction between the steel material 50 and the working surface 11 of the straightening plate inlet section, while also protecting the working surface 11.

[0040] Specifically, the friction plate 40 is detachably provided at the inlet section of the straightening plate body 10 , so that the friction plate 40 can be replaced as needed.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
