Abstract

The utility model discloses a withdrawal straightening machine set with equal-machine-frame multi-point successive approximation straightening technology, which belongs to the field of machinery casting. The utility model mainly solves the problem that the ordinary withdrawal straightening machine set is not suitable for straightening large-cross-section alloy steel materials, the withdrawal straightening machine set is provided with at least five withdrawal straightening machines, the number of the straightening points of the withdrawal straightening machine set is the same as that of straightening machines, both sides of the withdrawal straightening machines are provided with support rollers, and table frames with adjustable radians are fixed at the bottom part of the withdrawal straightening machines. The withdrawal straightening machine set uses an equal-machine-frame multi-point successive approximation straightening mode for straightening the large-cross-section alloy steel materials, internal and external defects generated because of insufficient straightening points are overcome, the investment of the withdrawal straightening machines is reduced on the premise of ensuring the straightening effect, and the production cost of enterprises is reduced.

Description

The withdrawal straightening stands that the continuous progressive straightening technology of frame multiple spot such as has
Technical field
The utility model relates to the withdrawal straightening stands of a kind of steel billet aligning usefulness, specifically a kind of use when being suitable for big section material aligning etc. the withdrawal straightening stands of frame multiple spot progressive straightening technology.
Background technology
The withdrawal straightening stands of common steel billet aligning usefulness is proper to light section material aligning, the aligning frame number of withdrawal straightening stands is less, the aligning point is also fewer, radius of curvature changes greatly, but during for big section alloy steel continuous casting base aligning, because aligning is fewer, radius of curvature changes greatly, be easy to make the surface and the inner defective that produces of steel alloy, and aligning is of low quality, is difficult to meet the needs of production; So common withdrawal straightening stands is unsuitable for the aligning to big section alloy steel material very much.
Summary of the invention
Many weak points at existing withdrawal straightening stands, it is a kind of simple in structure that the utility model provides, have a plurality of aligning points, the withdrawal straightening stands of the progressive continuous straightening technology of frame multiple spot such as use, realization is to the aligning of big section alloy steel material, both guarantee leveling effect, and can guarantee the inherence and the external quality of steel billet again.
The concrete technical scheme that the utility model adopts is: the withdrawal straightening stands that the continuous progressive straightening technology of frame multiple spot such as has, comprise the straightening machine, it is characterized in that: described withdrawal straightening stands is provided with at least five straightening machines, the aligning point of withdrawal straightening stands is identical with the straightener number, and both sides are provided with carrying roller before and after the straightening machine.The quantity of straightening machine can be set according to the technological requirement of section material, guarantee the straightening effect, the aligning point is many, it is less to guarantee that radius of curvature changes, can guarantee to be aligned the inherent quality and the outer surface quality of material preferably, guarantee that under the control of frequency converter straightening speed is unified, carrying roller can play the material of aligning and support and transitional function, makes strand successfully by straightening.
The straightening machine is fixed on the different bases, to satisfy the requirement that straightening strand different curvature radius changes, guarantees that leveling effect is better.
The beneficial effects of the utility model are: this withdrawal straightening stands uses the technology of the continuous progressive straightening of multiple spot that steel billet is aligned, overcome continuous casting steel billet because of the not enough inside and outside defective that produces of aligning point, can realize etc. that frame participates in the work of straightening, reduced the quantity of straightening machine relatively, guaranteeing under the prerequisite of leveling effect, reduced drawing the input of sedan-chair machine, reduced the production cost of enterprise.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model
Among the figure: 1 first straightening machine, 11 second straightening machines, 12 the 3rd straightening machines, 13 the 4th straightening machines, 14 the 5th straightening machines, 2 carrying rollers, 3 steel billets, 4 stands.
The specific embodiment
As shown in Figure 1, the withdrawal straightening stands of the continuous progressive straightening technology of frame multiple spot such as this has, be provided with five straightening machines, the straightening machine can be arranged on the stand 4 of different radians according to the technological requirement of strand radius of curvature, to satisfy the aligning of this straightening machine to steel billet, both sides are provided with carrying roller 2 before and after the straightening machine, and the straightening machine can be by drawing and align steel billet 3; The steel billet of being aligned 3 becomes R2 through carrying roller and the first straightening machine, 1 back steel billet radius by R1, behind the second straightening machine 11, the steel billet radius becomes R3 by R2, behind the 3rd straightening machine 12, the steel billet radius becomes R4 by R3, behind the 4th straightening machine 13, the steel billet radius becomes R5 by R4, behind the 5th straightening machine 14, the steel billet radius becomes straight steel billet by R5, has finished the overall process of steel billet aligning.Each straightening machine all contains an aligning point, passed through R2 by R1 by the radius of the steel billet in the aligning process 3, R3, R4, R5 is until becoming straight steel billet, because the aligning point is comparatively intensive, the steel billet radius of curvature of being aligned changes evenly, so the aligning adaptability to changes on each point is all balanced comparatively speaking, owing to be etc. again the continuous progressive straightening of frame multiple spot, strain in the steel billet aligning district is carried out continuously, strain rate is similar to a constant, scientific utilization aligning curve, structure is more reasonable, has improved the quality of strand greatly, can add other straightening machines and carry out back work, utilize existing resources to improve the quality of strand greatly.

Claims (1)
