Description
Technical Field
The utility model relates to a steel rolling production technical field especially relates to a buckle formula band steel ground roller.
Background
A flat steel and round steel rolling production line produced by combining flat circles needs to be arranged according to order quantity requirements and actual plans, and the flat steel mode and the round steel mode are switched to the production line irregularly. Because the rolling line runway is a common part of the whole rolling line, namely the same runway system is used for rolling flat steel or round steel. As is well known, when the ground roller drives the flat steel to advance, the contact between the flat steel and the ground roller belongs to surface contact; when the round steel is driven to advance by the ground roller, the flat steel is in line contact with the ground roller. These two different contact modes coexist on the same production line.
The rolling production belongs to hot working, and after high temperature round steel was carried on the runway for a long time, the ground roller received wearing and tearing and produced "taking out the groove", and such taking out the groove is little to the round steel influence, nevertheless when the band steel passes through on such runway, takes out the groove and very easily causes the fish tail to the band steel lower surface to influence product quality, reduce product yield, directly produce the waste product even.
To circumvent this risk, the ground rollers must be very wear resistant. However, the whole rolling line is very long, the number of the ground rollers is very large, if the whole ground rollers are made of wear-resistant alloy, the production cost is reduced and the disadvantages are avoided, and in order to save energy and reduce cost, the conventional treatment mode is to separately manufacture a wear-resistant roller sleeve and a common shaft and then perform welding combination. However, the roller sleeve and the shaft are made of different materials, so that the welding performance is extremely poor, and the service cycle of the ground roller is short due to the desoldering. The bolt is used for reinforcement, but the bolt hole position needs to be increased by increasing the bolts, the use amount of the wear-resistant alloy is increased, the cost is increased, and the benefit is not great.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a buckle formula band steel ground roller is provided to above-mentioned prior art, can increase the live time of ground roller, avoid the desoldering between ground roller shell and the ground roller axle, practice thrift spare part cost, promote product quality simultaneously.
The utility model provides a technical scheme that above-mentioned problem adopted does: a buckle type flat steel ground roller comprises a roller sleeve, an inner embedded plate, a roller shaft and a positioning pin, wherein steps are arranged on the inner peripheral wall of the roller sleeve, a plurality of boss clamping blocks are formed on the surface of the steps, groove clamping grooves matched with the boss clamping blocks are formed in the inner embedded plate, the boss clamping blocks and the groove clamping grooves are correspondingly embedded to enable an embedded plate to be positioned on the steps, and the embedded plate is fixed on the steps through the positioning pin; the roller shaft is arranged in the center of the roller sleeve, and the end part of the roller shaft is supported in the center of the embedded plate.
The roller sleeve is made of wear-resistant alloy, and the embedded plate and the roller shaft are made of the same common alloy.
Compared with the prior art, the utility model has the advantages of: the utility model discloses modified buckle formula band steel ground roller, fundamentally has stopped because of welding the not firm condition of leaning on because of the material difference between ground roller shell and the ground roller, reduces the wear-resisting alloy rate of utilization, reduces the basis of stick spare part cost, has effectively reduced the fault rate of ground roller. The ground roller has long service life, only needs to be replaced when the wear degree of the ground roller reaches the replacement requirement specified in the ground roller, and the rest ground rollers only need to be maintained daily.
Drawings
Fig. 1 is a schematic structural view of a buckle-type flat steel ground roller according to an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the buckle type flat steel ground roller in this embodiment, the buckle type flat steel ground roller includes a roller sleeve 1, an embedded plate 2, a roller shaft 3 and a positioning pin 4, a circle of circumferential steps 7 are provided on the inner circumferential wall of the roller sleeve 1, a plurality of boss fixture blocks 5 are formed on the step surface of the steps 7, the embedded plate 2 is a disc-shaped disc, the roller sleeve 1 can be placed inside, and is supported on the steps 7, groove slots 6 matched with the boss fixture blocks 5 are formed on the matching surface of the embedded plate 2 and the steps, the boss fixture blocks 5 are embedded corresponding to the groove slots 6 to position the embedded plate 2 on the steps 7, so that a radial fixing effect can be effectively achieved, no relative radial movement between the roller sleeve 1 and the embedded plate 2 is ensured, a certain pre-tightening degree can be ensured in the axial direction, the embedded plate 2 is fixed on the steps 7 through the positioning pin 4, and the axial fixing is achieved. The roller axle 3 is arranged in the center of the roller sleeve 1, and the end part is supported in the central hole of the inner panel 2.
The buckle formula band steel ground roller of above-mentioned structure has effectively reduced the fault rate of ground roller, and convenient equipment has reduced wearing and tearing.
Although the preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that modifications and variations of the present invention are possible to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
