Description

Technical Field

[0001] The utility model relates to cold rolling production, in particular to a steel piling stop device in cold rolling production. Background Art

[0002] Cold-rolled ribbed steel bar production equipment generally mainly consists of a loading machine, a descaling machine, a rolling mill, an intermediate frequency heating furnace and subsequent material receiving equipment. During the production process, due to some equipment failures, the steel bars will be blocked at some points. For example, the ceramic coil lining in the intermediate frequency heating furnace is prone to cracking, and after cracking, the steel bars can be blocked and cannot run. The rolling process is arranged upstream of the intermediate frequency heating furnace, and the rolling mill is generally a power-driven active structure, driving the steel bars to run at high speed through the rolls. When the equipment behind the rolling mill fails and blocks the steel bars, the steel bars will stack up in this section, and the stacked steel bars will cause secondary equipment accidents or even personal safety accidents. Therefore, a steel piling stop device needs to be configured on the cold rolling production line. When steel piling occurs, it can detect it in time and control the equipment to stop running in time to prevent the occurrence of secondary accidents. CN105363791A discloses a steel piling emergency stop device, adopting a technical solution similar to a pull rope switch. This method can prevent steel piling accidents, but when steel piling occurs, the pull rope is easy to entangle with the steel bars, and the subsequent treatment is more cumbersome, and often a new pull rope needs to be replaced; CN103170505A discloses a cold-rolled wire rod steel piling detection and scrap steel collection device, but its structure is relatively complex, and when steel piling occurs, the steel piling detection equipment itself is prone to failure due to stress. Summary of the Invention

[0003] The purpose of the utility model is to provide a steel piling stop device in cold rolling.

[0004] To achieve the purpose of the utility model, the following technical solution is adopted: A steel piling stop device in cold rolling includes a box body for the steel bars to pass through. Through holes corresponding to each other front and back for the steel bars to pass through are opened on the front and rear end faces of the box body. An elastic induction plate is fixedly arranged in the box body near the rear end face of the box body. The elastic induction plate is a conductive plate. One end of the elastic induction plate is fixedly connected to the box body through an insulator, and the other end is suspended. A through hole corresponding to the through hole is opened on the elastic induction plate. The diameter of the through hole is larger than that of the through hole. The elastic induction plate is electrically connected to the high potential end, and a potentiometer is connected to the high potential end.

[0005] Further, the lower end of the elastic induction plate is fixedly connected to the box body through an insulator, and the upper end is suspended.

[0006] Further, the box body is an openable closed structure or a partially closed structure.

[0007] The positive and beneficial effects of the present utility model are as follows: The device has a simple structure, reliable detection, and convenient post-treatment. After the steel pile-up is removed, the elastic steel plate automatically resets. Description of the Drawings

[0008] Figure 1 is a schematic diagram of the present utility model. Detailed Embodiment

[0009] To more fully explain the implementation of the present utility model, implementation examples of the present utility model are provided. These implementation examples are only elaborations of the present utility model and do not limit the scope of the present utility model.

[0010] With reference to the accompanying drawings, the present utility model is further explained in detail. The marks in the drawings are as follows: 1: box body; 2: front material passing hole; 3: rear material passing hole; 4: elastic induction plate; 5: through hole; 6: insulator.

[0011] As shown in the accompanying drawings, a steel pile-up stopping device in cold rolling includes a box body 1 for steel bars to pass through. The box body is an openable closed structure or a partially closed structure. Material passing holes for steel bars to pass through are provided on the front and rear end faces of the box body corresponding to each other. In the figure, 2 is the front material passing hole and 3 is the rear material passing hole. An elastic induction plate 4 is fixedly arranged in the box body near the rear end face of the box body. The elastic induction plate is a conductive plate. One end of the elastic induction plate is fixedly connected to the box body through an insulator 6 and the other end is suspended. In this embodiment, the lower end of the elastic induction plate is fixedly connected to the box body through an insulator 6 and the upper end is suspended. Of course, it is also possible to use the left end of the elastic induction plate fixedly connected to the box body through an insulator and the right end suspended. A through hole 5 corresponding to the material passing hole is provided on the elastic induction plate. The diameter of the through hole is larger than that of the material passing hole. The through hole is large to prevent the steel bar from contacting the edge of the through hole during normal production and generating false alarm signals. As an optimized preventive measure, an insulating sleeve can be fixedly arranged around the periphery of the through hole. In this way, even if the steel bar touches the edge of the through hole during operation, it will not cause a potential change in the potentiometer. The elastic induction plate is electrically connected to the high potential end. The potential of the high potential end is less than or equal to 36V (human body safety voltage), preferably below 24V. In actual use, 5V or 12V can meet the requirements. A potentiometer is connected to the high potential end. The potentiometer is used to detect the potential level of the elastic induction plate.

[0012] When this steel pile-up detection device is in use, the steel bar passes through the front material passing hole and exits through the rear material passing hole. When there is a blockage in the downstream of the production line, the steel bars in the box body will stack up because they are in a free state. The stacked steel bars press the elastic induction plate from the front side, causing it to tilt backward and contact the box body. At this time, the high potential end will be grounded and the potential will change. By monitoring the change in the potential on the induction plate, it can be known that there is a steel pile-up. After the steel pile-up occurs, the production line is controlled to stop. While dealing with the fault point, the lid is opened to take out the stacked steel bars in the box body, and then the wire is re-threaded to resume production.

[0013] After describing the embodiments of the present invention in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention all belong to the scope of the technical solution of the present invention, and the present invention is not limited to the embodiments described in the specification either.
