Threading guide plate platform device suitable for various working conditions as well as use method thereof

Abstract

The invention discloses a threading guide plate platform device suitable for various working conditions as well as a use method thereof. The device comprises a swinging frame, a hydraulic cylinder, afirst pressing roll and a second pressing roll; one end of the swinging frame is hinged with a steering pinch roll; the head of the hydraulic cylinder is hinged and connected with the other end of theswinging frame; the first pressing roll is rotatably arranged at the other end of the swinging frame; the two ends of the second pressing roll are arranged at the other end of the swinging framer through a rotatable baffle; the rotatable baffle and the other end of the swinging frame are rotatably connected through a rotatable pin shaft; when the thickness of band steel is less than 4 mm, the rotatable baffle rotates the second pressing roll on back part, opposite to the first pressing roll, of the swinging frame; when the thickness of the band steel is more than or equal to 4 mm, the rotatable baffle rotates the second pressing roll to the front part, close to the first pressing roll, of the swinging frame; and the rotatable baffle is fixedly connected with the swinging frame through a fixing pin. The threading guide plate platform device suitable for various working conditions can realize leading of the band steel with large thickness range and strength range of the same machine unit.

Description

technical field [0001] The invention relates to a strip threading guide platform before strip coiling equipment in the metallurgical industry, in particular to a strip threading guide platform device located in front of a coiler of a cold rolling unit and suitable for four working conditions of strips with various thicknesses. Its use method can solve the problem of introducing the strip steel into the reel and coiling it into a coil when the thickness range and strength range of the incoming strip steel are large. Background technique [0002] In the cold rolling mill, a threading guide table is generally installed in front of the coiler to introduce the strip steel into the coiler reel, and the head of the guide table is generally set as a pressure roller, which presses the tail of the steel coil to prevent the Strip flick. For strip steel with low yield strength and thickness less than 4mm, the strip guide plate is generally used to guide the strip steel into the belt co...

AI Technical Summary

Problems solved by technology

For strip steel with low yield strength and thickness less than 4mm, the strip guide plate is generally used to guide the strip steel into the belt coiler, and the belt coiler is used to help the strip steel to be coiled on the coiler drum; but for If the yield strength is high, the thickness of the strip steel is greater than 4mm, or even greater than 6mm, and the strip shape is not good, forcibly using a belt coiler to assist coiling will not only fail to realize the coiling function, but will also damage the belt.
