Problems solved by technology

In the existing coiling facilities, the coiling-assisting roller adopts a three-roller surrounding arrangement, the pressure points are distributed in a space of 120 degrees, the pressure points are few, the coiling-assisting pressing force is large, the leading-in performance of the strip during the coiling operation and the uniform winding performance None of them are ideal. When the rolling quality of the plate is not good (such as warped head, the head is biased to the driving s

Example Embodiment

[0015] The contribution of the present invention to the prior art is to change the traditional three-point configuration of the roll-up roll to a three-point or more configuration. In the illustrated embodiment, a four-point configuration is used. The number of rolls is four, namely No. 1, 2, 3, and 4. The four rolls 20, 21, 22, 23 are distributed around the mandrel 19, each A roll is rotatably supported on a swing arm. One end of each swing arm is a hinged shaft end, and the other end is hingedly connected to the piston rod of a hydraulic cylinder. The cylinder body of each hydraulic cylinder is a fixed part, and the piston rod acts on hydraulic power. When the lower work reciprocates, the swing arm is driven to swing with the hinge axis as the axis.

[0016] Still see figure 1 . When the number of rolls is four, the four rolls should be distributed in a 360-degree circle. The specific position of each roll should be combined with the arrangement of the swing arms and hydraulic c...

Abstract

A hot-rolled sheet coiling machine with better coil-helping performance has a reel, coil-helping rollers, swinging arms for supporting said coil-helping rollers, and hydraulic cylinders for driving said swinging arms. It features that 1-3 coil-helping roller are additionally used for increasing the points to where the pressure is applied, so improving its coil-helping performance.

Description

technical field [0001] The invention relates to an improved coiler used in a thin plate rolling production line, which belongs to the technical field of plate rolling. Background technique [0002] The steel billets are processed into thin strips after initial rolling, finishing rolling, and cutting to length, and then sent to the coiling facility through the conveying roller table, where they are coiled into standard coils with a certain thickness, and then bundled and packaged. After the process, it becomes the final product. The coiler used in the hot-rolled sheet production line is generally composed of a mandrel, a mandrel rotation drive, a coiling roll arranged around the mandrel, a swing arm where the roll is located, and a hydraulic cylinder that drives the swing arm. When the front end of the formed sheet strip enters the positions of the rolling rollers in turn, the hydraulic cylinders of the rolling rollers drive the rolling rollers to move closer to the mandrel ...
