Abstract
A multi-slitting rolling technology for rod materials includes such steps as primary rolling, intermediate rolling, and fine rolling consisting of preslitting rolling, finishing, final preslitting and slitting rolling. It features high shape and size consistence.
Description
Technical field
The present invention relates to a kind of multi wire cutting rolling technology of stress metal process technology, particularly a kind of bar.
Background technology
Bar multi wire cutting rolling technology is exactly to be the identical multi-thread bar of specification with a blank is longitudinally simultaneously rolling, thereby improves utilization rate of equipment and installations and output.Its basic process of production generally includes just, in, three sections of finish rolling, all finish by the road for every section by many milling trains, every milling train is finished the rolling process of a passage.Be carved with the groove of given shape on the roll of each milling train, this groove is also referred to as " pass ", and the feed inlet and outlet of every milling train all is provided with the device of restriction blank horizontal looseness, is also referred to as " guide and guard ".Through breaking down, in rectangular cross section blank after rolling when advancing to the finish rolling section, then by it directly being rolled into the rolled piece in parallel with similar section configuration more than two through unique a pair of pre-cutting, pass on the cutting passage, this parallel connection rolled piece weakness links to each other and is convenient to and separates, and the slitting wheel cutting in the cutting passage is the bar of corresponding number again.Mainly there are following some shortcomings in above-mentioned bar multi wire cutting rolling technology: 1, as a unique pre-slitting pass, it must guarantee the uniformity of cutting; And because the pre-splitting rolling process in this multi wire cutting rolling operation is the inhomogeneous deformation process, the absolute spread of its rolled piece is bigger and restive than the rolled piece absolute spread in traditional one-strand roller process; Therefore, in pre-cutting process, the uneven defective of size between each line occurs, influence the shape and the dimensional uniformity of final finished through regular meeting; Under these circumstances, can only rely on the clamping action of pre-guide and guard, guarantee the uniformity of rolled piece, thereby cause this pre-cutting import guide and guard Installation and Debugging difficulty, in fact the uniformity of each lines type only depends on guide and guard to guarantee.2, owing to had only unique together pre-cutting passage before the cutting operation, therefore, the rolling load of this pre-cutting milling train is very big, and operating mode is difficult to stablize, and operation troubles is more.
Summary of the invention
The object of the present invention is to provide a kind of rolling load equilibrium, can improve finished form and dimensional uniformity significantly, and to little, the stable bar multi wire cutting rolling technology of pre-Cutting guide dependence.
For realizing purpose of the present invention, a kind of bar multi wire cutting rolling technology, comprise breaking down, in roll and finish rolling, be provided with not pre-cutting passage in road and splitting rolling passage in the finish rolling section, before the pre-cutting passage in described not road, be provided with together pre-cutting passage at least, after the pre-cutting passage of per pass, be respectively arranged with the arrangement passage that is used to control the rolled piece width together accordingly.
Advantage of the present invention is: the shape of finished product bar and dimensional uniformity are good, and product quality is improved significantly; Simultaneously, since second pre-cutting, the shape of rolled piece and pass is very approaching, so the time pre-cutting become homogeneous deformation character, its absolute spread is less, so the width of the width of pre-slitting pass at this moment and supplied materials stripe shape is very approaching, like this, pass is stronger to the stationkeeping ability of rolled piece, be that rolled piece has the ability of centering voluntarily in the operation of rolling, thereby reduced dependence, improved the stability of rolling system operation pre-Cutting guide.
Description of drawings
Below in conjunction with accompanying drawing bar multi wire cutting rolling technology of the present invention is described in further detail:
Fig. 1 is the pass schematic diagram of each passage of finish rolling operation in the bar multi wire cutting rolling technology of the present invention.
Fig. 2 is the cross sectional representation of the corresponding rolled piece after each the passage groove rolling of finish rolling operation in Fig. 1.
Among the figure: 1, the pre-slitting pass of slubbing, 2, slubbing width arrangement pass, the pre-slitting pass in 3, two roads, 4, two road width arrangement passes, 5, the pre-slitting pass in road not, 6, slitting pass, 11, the pre-cutting base of slubbing shape, 21, slubbing width arrangement base shape, 31, the pre-cutting base in two roads shape, 41, two road width arrangement base shapes, 51, the pre-cutting base in road shape not, 61, cutting base shape.
The specific embodiment
The present invention is embodiment with the three-line syncopate, a kind of bar multi wire cutting rolling technology, its basic working procedure comprise with blank through breaking down, in roll finish rolling, make rod product then.In the finish rolling section, be provided with six milling trains altogether, they bear the pre-cutting of slubbing, the arrangement of slubbing width, the pre-cutting in two roads, two road width arrangements, not pre-cutting in road and cutting operation successively, the roll pass that is provided with on six milling trains corresponds respectively to six kinds of passes as shown in Figure 1, i.e. the pre-slitting pass 1 of slubbing, slubbing width arrangement pass 2, the pre-slitting pass 3 in two roads, two road width arrangement passes 4, not pre-slitting pass 5 in road and slitting pass 6; Correspond respectively to six kinds of base shape cross-sectional views among Fig. 2 through the blank shape of above-mentioned six kinds of groove rollings, i.e. the pre-cutting base of slubbing shape 11, slubbing width arrangement base shape 21, two roads pre-cutting base shape 31, two road width arrangement base shapes 41, the not pre-cutting base in road shape 51 and cutting base shape 61.This blank along with different roll Pass change, thereby is rolled into cun stable rod product to the greatest extent continuously, equably in whole finish rolling process.
In the above-described embodiments, owing between the pre-cutting operation of pre-cutting of slubbing and two roads, be provided with slubbing width arranging process, between the pre-cutting operation of pre-cutting in two roads and three roads, be provided with two road width arranging processes, therefore, can make pre-splitting rolling process become more all even stable, the horizontal looseness of rolled piece reduces, and the bar quality is improved significantly.
In the present invention, the above embodiments can only not be provided with once pre-cutting passage with width arrangement passage before the pre-cutting passage in road yet; Pre-cutting passage in three roads or more pre-cutting passage also can be set in addition, the back of the pre-cutting passage of per pass is provided with width arrangement passage more respectively, but passage can increase unnecessary manufacturing cost and operating cost too much, therefore, be the best to set up two pre-cutting passages and two corresponding width arrangement passage effects.
