Description

A kind of novel cold bed rolling disk

Technical field

The utility model belongs to machining equipment technical field, particularly the novel cold bed rolling disk of one.

Background technology

Cold bed is one of key equipment of heavy and medium plate mill group, and it is whether up-to-standard that the quality of cold bed decides plate surface, and its stuctures and properties directly affects final mass and the output of product.Rolling Disc Cooling Bed due to its not easily scratching steel plate surface, excellent, cheap, the structure of cooling effect are relatively simple, fault rate is lower and the advantage such as ease of maintenaince replacing and adopt by most of medium plate manufacturer.The cold bed that current most of steel rolling mill uses normally disc type cold bed, major function be by high-temperature straightening after the even natural air cooling of medium plate, its main body is made up of the rolling disk axle that many groups are parallel to each other staggered, every root rolling disk is driven separately by motor, often organize on rolling disk axle and 23-24 rolling disk is installed, rolling disk diameter, probably at about 600mm, drives steel plate steadily movement forward by the rotation of rolling disk, makes steel plate obtain Slow cooling.Armrest sleeve connection in the middle of every root rolling disk axle.Rolling disk is owing to directly can contact with roller, and wearing and tearing are very fast.Prior art Problems existing has: when a rolling disk damages and needs to change, rolling disk all above of just must dismantling, extends downtime, again lost labor; Simultaneously rolling disk operationally can stick on rolling disk axle by temperatures involved, changes very inconvenient, from rolling disk axle gets on after usual workman adopts the method for knocking rolling disk to make rolling disk loosen, easily damages rolling disk axle.

Summary of the invention

For overcoming defect and the deficiency of prior art, the utility model provides a kind of novel cold bed rolling disk, convenient disassembly, quick, saves cost.

For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of novel cold bed rolling disk, and comprise roller and be located at the split type rolling disk outside roller, roller center is provided with axis hole, and outside spaced set has the spoke with screw; Split type rolling disk top is leaf plank, and bottom is arm plate; Arm plate is provided with the screw matched with roller; Leaf plank both sides are provided with arc-shaped slot; On roller and split type rolling disk, corresponding screw quantity is at least a pair.

Compared with prior art, the beneficial effects of the utility model are:

1, roller and split type rolling disk is adopted, roller center is provided with axis hole, outside spaced set has the spoke with screw, split type rolling disk top is leaf plank, bottom is be provided with the screw arm plate matched with roller, only need split type rolling disk to pull down during dismounting to change, save labor and raw material;

2, the leaf plank both sides of split type rolling disk are provided with arc-shaped slot, and arc-shaped slot matches formation hollow, and the phenomenon that can effectively avoid rolling disk to be at high temperature adhered, more easily dismantles.

Accompanying drawing explanation

Fig. 1 is the structural representation of roller;

Fig. 2 is the structural representation of split type rolling disk;

Fig. 3 is the left view of Fig. 2.

Detailed description of the invention

As shown in Figure 1, Figure 2 and Figure 3, a kind of novel cold bed rolling disk, the split type rolling disk 2 comprising roller 1 and be located at outside roller, roller center is provided with axis hole 3, and outside spaced set has the spoke 5 with screw 4, and spoke quantity is three; Split type rolling disk top is leaf plank 6, and bottom is arm plate 7; Arm plate is provided with the screw matched with roller; Leaf plank both sides are provided with arc-shaped slot 8, and arc-shaped slot coordinates formation hollow between two, and on roller and split type rolling disk, corresponding screw quantity is two right.During work, be first located at by roller housing on rolling disk axle, split type rolling disk, respectively by being bolted on the spoke of roller, compresses between split type rolling disk mutually; First take off bolt during dismounting, radial direction knocks split type rolling disk, unloads split type rolling disk.
