Abstract
The invention provides a roller assembly for slitting and rolling of an elevator guide rail and a rolling method, relates to the field of rolling of deformed steels in profile steel rolling, and aims at solving the problem of asymmetric section shape of a product in the current production of the profile steel of the elevator guide rail. The roller assembly comprises an upper horizontal roller, a lower horizontal roller, a left side vertical roller and a right side vertical roller, wherein an upper left rolling groove is formed in the upper horizontal roller, and a lower left rolling groove is formed in the lower horizontal roller; a left elevator guide rail hole pattern is formed among the upper left rolling groove, the lower left rolling groove and the left side vertical roller; an upper right rolling groove is formed in the upper horizontal roller, and a lower right rolling groove is formed in the lower horizontal roller; a right elevator guide rail hole pattern is formed among the upper right rolling groove, the lower right rolling groove and the right side vertical roller; the left elevator guide rail hole pattern and the right elevator guide rail hole pattern communicate with each other; an upper shearing opening is formed in the upper left rolling groove, and a lower shearing opening is formed in the lower right rolling groove. With the adoption of the roller assembly, a pair of semi-finished elevator guide rails which are integrally connected can be rolled; after entering the left elevator guide rail hole pattern and the right elevator guide rail hole pattern, the semi-finished elevator guide rails can be sheared into two finished products through the corresponding shearing openings. The roller assembly has the advantage that the section shape of the product is symmetric.
Description
Technical field:
The present invention relates to deformed steel rolling field in rolling of sectional iron, the roller assembly used when especially relating to a kind of rolling cage guide shaped steel and milling method.
Background technology:
Shaped steel is one of principal item of steel products, is widely used in the industries such as agricultural, transportation, manufacturing industry and building industry.Shaped steel kind is a lot, and section configuration is complicated, and the steel ingot of simple shape or steel billet are passed through several two or more grooved rolls by people successively, is rolled distortion with the product obtaining required section configuration, size and performance.In the production of steel, except small part adopts casting and forging etc. directly to make except device, all the other iron and steel accounting for more than 90% need be become a useful person through rolling.Though some steel non-immediate are produced by mill, also need provide blank by mill, therefore in modern steel integrated complex, produce the Rolling production of last link as steel, in national economy, occupy extremely important status.
At present, some light section production line the built time is longer, and technological level is backwardness comparatively, and original product version is single.For improving production line service efficiency, the potential of Development and Production line, transforms accordingly to it, can produce deformed steel.Meanwhile, in recent years along with the expansion in market, market increases year by year to the demand of cage guide, therefore for meeting the needs in market, on the basis of existing light section production line, the cage guide that production economy benefit is outstanding one of can yet be regarded as more preferably is selected.But, be all single rolling during production cage guide shaped steel at present, there is product cross section shape asymmetric, of poor quality, the problems such as production efficiency is low.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of good product quality, the roller assembly used during production efficiency height cage guide splitting rolling and milling method.
Above-mentioned purpose is achieved in that described roller assembly comprises horizontal roller, lower horizontal roller, left side edger roll, right side edger roll, wherein go up horizontal roller and lower horizontal roller is oppositely arranged up and down, left side edger roll is arranged on the left side of horizontal roller and lower horizontal roller, right side edger roll is arranged on the right side of horizontal roller and lower horizontal roller, upper horizontal roller is provided with upper left groove along roll footage direction, lower horizontal roller is provided with the lower-left groove corresponding with upper left groove along roll footage direction, a complete cage guide pass is formed between upper left groove and lower-left groove and left side edger roll, i.e. left cage guide pass, upper horizontal roller is provided with upper right groove along roll footage direction, lower horizontal roller is provided with the bottom right groove corresponding with upper left groove along roll footage direction, also a complete cage guide pass is formed between upper right groove and bottom right groove and right side edger roll, i.e. right cage guide pass, left cage guide pass and right cage guide pass symmetrical, distance between described upper left groove and ground is less than the distance between upper right groove and ground, and the distance between described lower-left groove and ground is less than the distance between bottom right groove and ground, namely left cage guide pass is lower than right cage guide pass, described left cage guide pass is connected with right cage guide pass, and the low order end of upper left groove is provided with clip, and the high order end of bottom right groove is also provided with lower clip, and upper clip and lower clip are oppositely arranged.
Milling method: first roll out a pair cage guide semi-finished product linked together with common rolled piece, the cage guide semi-finished product described in this are cut into two finished products through clip after entering into described left cage guide pass and right cage guide pass.
Advantage of the present invention is: can produce a pair finished product, product cross section symmetrical shape, quality is good, and production efficiency is high simultaneously.Test shows, while enhancing productivity, the present invention can also significantly improve rolling stability, and the running of roller assembly and milling train is very steady, and maintenance cost significantly reduces.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of roller assembly in the present invention, and in figure, 9 is milling train.
Accompanying drawing 2 is schematic diagrames of a pair cage guide after rolling cutting.
Detailed description of the invention:
With reference to accompanying drawing 1, described roller assembly comprises horizontal roller 1, lower horizontal roller 2, left side edger roll 3, right side edger roll 4, wherein go up horizontal roller and lower horizontal roller is oppositely arranged up and down, left side edger roll is arranged on the left side of horizontal roller and lower horizontal roller, right side edger roll is arranged on the right side of horizontal roller and lower horizontal roller, upper horizontal roller is provided with upper left groove along roll footage direction, lower horizontal roller is provided with the lower-left groove corresponding with upper left groove along roll footage direction, a complete cage guide pass is formed between upper left groove and lower-left groove and left side edger roll, i.e. left cage guide pass 5, upper horizontal roller is provided with upper right groove along roll footage direction, lower horizontal roller is provided with the bottom right groove corresponding with upper left groove along roll footage direction, also a complete cage guide pass is formed between upper right groove and bottom right groove and right side edger roll, i.e. right cage guide pass 6, left cage guide pass and right cage guide pass symmetrical, distance between described upper left groove and ground is less than the distance between upper right groove and ground, and the distance between described lower-left groove and ground is less than the distance between bottom right groove and ground, namely left cage guide pass is lower than right cage guide pass, described left cage guide pass is connected with right cage guide pass, and the low order end of upper left groove is provided with clip 7, and the high order end of bottom right groove is also provided with lower clip 8, and upper clip and lower clip are oppositely arranged.
