Description

Technical Field

[0001] The utility model relates to the technical field of guide guards, in particular to a guide guard device at the outlet of a rolling mill. Background Art

[0002] A guide guard is a device installed before and after the roll pass during the section steel rolling process to help the rolled piece enter and exit the roll pass. Generally, the distance between the guide rollers of the guide guard cannot be adjusted, and it can only be used to guide one type of steel. When the material needs to be changed, the distance between the guide rollers of the guide guard needs to be adjusted, and the disassembly and fixation are rather troublesome. At the same time, iron filings will adhere to the guide guard during use, and the long-term accumulation will affect the guiding effect, and manual cleaning is rather troublesome. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is that the existing guide guard is inconvenient to adjust the distance between the guide rollers, and at the same time, iron filings and impurities adhere to the guide rollers during use and are not easy to clean, affecting the guiding effect.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: The guide guard device at the outlet of the rolling mill proposed by the utility model includes a guide guard support body. A guide guard groove is provided on one side of the guide guard support body. Limit sliding grooves are correspondingly provided on the bottom wall and the top wall of the guide guard groove. A guide roller assembly is arranged in the limit sliding grooves. An adjusting screw is provided on one side of the guide guard support body. The adjusting screw penetrates through and is arranged on the guide guard support body through threads. An adjusting knob is provided at one end of the adjusting screw.

[0005] Preferred Technical Solution 1: The guide roller assembly includes a guide support block and a guide roller. The guide support block is slidably arranged in the limit sliding groove. One end of the adjusting screw is rotatably arranged on the side wall of the guide support block. An installation groove is provided on one side of the guide support block. The upper and lower ends of the guide roller are rotatably arranged between the inner bottom wall and the top wall of the installation groove. Two groups of guide rollers are arranged in the limit sliding groove.

[0006] Preferred Technical Solution 2: In order to remove the iron filings and impurities adhering to the surface of the guide roller, a scraping plate is further provided on the side wall of the installation groove.

[0007] Preferred Technical Solution 3: A plurality of air blowing nozzles are evenly arranged on the inner side wall of the installation groove. An air blowing pipeline is arranged inside the guide support block. The air blowing pipeline is communicated with the air blowing nozzles to blow away the scraped iron filings and prevent them from adhering to the surface of the guide roller. A connecting head is provided at one end of the air blowing pipeline located on the outer wall of the guide support block for connecting with an external air source pipeline.

[0008] Preferred Technical Solution 4: A fixing plate is further provided at the bottom of the guide guard support body. A positioning hole is provided on the fixing plate.

[0009] The guide guard device at the outlet of the rolling mill proposed by the utility model has the following beneficial effects when adopting the above structure:

[0010] (1) The guard is stably installed and fixed through the provided guard support and fixed plate. The distance between the guide rollers can be adjusted flexibly and conveniently through the adjusting screw and the guiding support block sliding in the limit chute.

[0011] (2) The provided scraper and air nozzle cooperate to blow off the iron filings adhering to the guide rollers with the help of an external air source, ensuring the cleanliness of the guide roller surface, ensuring a good guiding effect, and eliminating the need for manual cleaning.
