Abstract
The invention discloses a wire rolling bending track guide groove for wire rods. The wire rolling bending track guide groove for the wire rods comprises an arc-shaped track side plate (1) arranged on a base (5). The underneath of the circular arc-shaped track side plate (1) is arranged on the base (5) by a plurality of arranged T-shaped slope guide rollers (2); and two horizontal free rollers (3) and two free rollers (4) are also arranged at the inner side of the circular arc-shaped track side plate (1) on the base (5). The wire rolling bending track guide groove for the wire rods with the structure has the beneficial effects that the scratch of the heads, tails and surfaces of red steel can be effectively reduced; the stability of the red steel on horizontal loops can also be improved; the cracking phenomenon of the heads and tails of finished products with the diameters not exceeding 12.0 mm (about 200-300 rings) is put an end to; the labor efficiency and the percent of pass of wire rod finished products are improved; the quality objection is also reduced step by step; and certain economic benefits are achieved.
Description
Technical field
The invention belongs to rolling machinery technical field, especially relate to a kind of for high-speed rod rolling line bend guide groove.
Background technology
In High Speed Wire Production Process, because of coil of wire finished product end to end defect do not cut only, and bring surface stroke (wiping) wound to be difficult to avoid, common building wire rod, to coil of wire finished product end to end defect do not cut only, and it is not high to bring surface to draw (wiping) requirement of hindering, but for Cold Heading Steel Wire for the purpose of cold-heading molding, (wiping) is drawn to its one integral piece coil of wire surface and hinders depth of defect, have very strict requirement.Show according to the study, when there is the dark pit of 0.05mm in one integral piece finished wire rod surface, will have an impact to follow-up cold working quality, draw (wiping) of wire surface hinders defect, because there is area of stress concentration around it, in cold deformation, if deflection comparatively conference initiation cracking phenomena, darker stroke (wiping) wound even can form similar folding blemish, and this defect cannot rely on heat treatment to eliminate.Conventional high-speed rod rolling line is designed to straight line, in recent years along with the development of thermal mechanical rolling technology, has transformed both at home and abroad or newly-built many high-speed rod rolling lines possessing thermal mechanical rolling function.Do not increase factory building length and area for reducing investment outlay, this kind of rolling line devises many places circular arc curve runway (guide groove) and Horizontal loose sleeve platform.At present, horse steel high-speed rod rolling line uses this many bends runway (guide groove) and Horizontal loose sleeve platform exactly, and this many circular arc curves runway (guide groove) and Horizontal loose sleeve platform, can meet the rolling requirements of common building wire rod substantially.But cold-forging steel workpiece front end and the quality instructions for use of afterbody on bend cannot be met.Special Surface Quality requires the higher high added value wire product such as bearing steel, spring steel, steel cord, cold-forging steel.Bend uses this conventional circular arc runway (guide groove) and Horizontal loose sleeve platform, cannot meet production technology user demand.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rolling line bend guide groove for wire rod for problems of the prior art, its objective is and avoid at Horizontal loose sleeve circular arc curve place, because of the surface tear of side and bottom surface end to end, and the finished product coil of wire cold heading cracking caused.
Technical scheme of the present invention is that this kind is included in for the rolling line bend guide groove of wire rod the runway circular arc side plate be arranged on base, and the below of described runway circular arc side plate is arranged on base by several the T-shaped slope deflector rolls arranged, on base and the inner side being positioned at runway circular arc side plate is also provided with two horizontal free rolls and two free rolls.
Described base is provided with two parallel grooves, and two horizontal free rolls are arranged in two parallel grooves respectively, are also provided with the adjustable mounting bracket for installing free roll in groove.
Two free rolls are arranged on the tail position of two horizontal free rolls respectively.
This kind with said structure can effectively reduce red steel toe, afterbody for the rolling line bend guide groove of wire rod, (wiping) wound is drawn on surface, the stability of red steel at Horizontal loose sleeve can also be improved, stop the following specification of Ф 12.0mm, finished product is (200-300 encloses left and right) cracking phenomena end to end, improve efficiency and wire rod product qualified rate, quality objection also gradually reduces, and plays certain economic benefit.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view of structure shown in Fig. 1.
In Fig. 1-2,1: runway circular arc side plate; 2:T type slope deflector roll; 3: horizontal free roll; 4: free roll; 5: base; 6: mounting bracket.
Detailed description of the invention
Fig. 1 is the structural representation of the present invention for the rolling line bend guide groove of wire rod, and Fig. 2 is the sectional view of structure shown in Fig. 1.Combined from structure shown in Fig. 1 and Fig. 2, this kind is included in for the rolling line bend guide groove of wire rod the runway circular arc side plate 1 be arranged on base 5, and the below of described runway circular arc side plate 1 is arranged on base 5 by several the T-shaped slope deflector rolls 2 arranged, on base 5 and the inner side being positioned at runway circular arc side plate 1 is also provided with two horizontal free rolls 3 and two free rolls 4.
Base 5 is provided with two parallel grooves, two horizontal free rolls 3 are arranged in two parallel grooves respectively, adjustable mounting bracket 6, two free rolls 4 be also provided with in groove for installing free roll 3 are arranged on the tail position of two horizontal free rolls 3 respectively.
By improved 6#A kink bend place, on the right side of rolling direction on circular arc runway (guide groove), increase by 7 T-shaped slope deflector rolls 2, before transforming, the sliding friction of runway (guide groove), changes into rolling friction.Simultaneously at 6#A Horizontal loose sleeve platform table top, then increase by two horizontal free rolls 3.Hot steel head is when 6#A kink plays cover, and red steel will steadily drop on kink centre position and two horizontal free rolls, and under the drive simultaneously advanced at utmost speed at red steel, generation rotates freely, and decreases red steel and looping bed mesa surfaces rubs.When hot steel afterbody receives cover, smooth transition to runway (guide groove) side, drives T-shaped slope deflector roll 2 to produce and rotates freely by red steel, plays minimizing and circular arc runway and to rub object.
By implementing, effectively can reduce by II pre-smart red steel toe, afterbody, (wiping) wound is drawn on surface, can also improve the stability of 6#A Horizontal loose sleeve.Stop (the following specification of Ф 12.0mm) finished product (200-300 encloses left and right) cracking phenomena end to end, meanwhile, also improve wire rod lumber recovery, preventing the generation causing quality objection because not cutting end to end only, playing certain economic benefit effect.
Estimate, annual improve wire rod finished product lumber recovery, day operating rate, reduce the generation etc. of quality objection, estimate more than 1,500 ten thousand/years.
