Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as Figure 1 to Figure 4 Shown, a kind of steering pinch roll that is used for the double channel production of cold-rolled strip steel, comprises frame 4, horizontal steering roll 1, horizontal and is positioned at the pinch roll 2 below steering roll 1 and is located at frame 4 The entrance guide plate 7 and the exit guide plate 9 are respectively located at the entrance and exit ends of the strip steel. The steering roller 1 is fixed on the frame 4 through the steering roller bearing seats at both ends, and the pinch roller 2 is fixed on the frame 4 through the pinch roller bearing seats 3 at both ends. Supported on two hydraulic cylinders 8 respectively, the two hydraulic cylinders 8 can simultaneously drive the pinch roller 2 (along the guide rail on the frame 4) up and down, and one end of the pinch roller 2 is connected with the motor...

Abstract

The invention relates to a deflector pinch roll for dual-channel production of cold-rolled steel strips. The deflector pinch roll comprises a rack, a deflector roll, a pinch roll, an inlet guide plate platform and an outlet guide plate platform, the inlet guide plate platform is integrally fixed on the rack, the outlet guide plate platform comprises a guide plate, two equally-high bearings respectively fixed on two pinch roll bearing blocks and two equally-high supports fixed on the rack, an articulated shaft is fixed on each bearing, a limit shaft is fixed on each support, round holes respectively matching with two articulated shafts are formed in one end of the bottom of the guide plate, and linear slots matching with the two limit shafts are respectively formed in the other end of the bottom of the guide plate. The deflector pinch roll can effectively avoid strip blocking at the dual-channel converging position during cold-rolled steel strip production and threading, smoothness in threading is assured, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, and in particular relates to a steering pinch roll used for double-channel production of cold-rolled strip steel. Background technique [0002] In the entrance section of the continuous cold-rolled strip production line, in order to ensure the continuous production of the process section, two uncoilers and corresponding equipment for processing the head and tail of the strip are usually equipped to form two staggered running strips. aisle. Between the entrance section and the entrance looper, there is a welding machine for tailor-welding the tail of the previous roll of strip steel and the head of the next roll of strip steel. In front of the welder, the two strip channels converge, and the strip is conveyed horizontally to the welder via a diverting pinch roll, which enters the diverting pinch roll obliquely downwards. The upper roll of the steering pinch roll is a steering roll, and the...
