Abstract

The utility model relates to a stable rolling control device, which is characterized in that: a position-guide device ascends gradually during rolling and generates a tensile force to enable a trapezoid projection of a made-up belt and a groove-type hole of a caliber roller to form an arc-shaped tight fit section (figure 4 and 5); a position-guide horizontal adjusting device 7 is used for slight horizontal adjustment of centering of the center of the made-up belt and the center of a roller caliber; since the arc-shaped tight fit section is formed between the trapezoid projection and the groove-type hole of the caliber roller and is adjacent to a rolling area, leftward and rightward movement of the made-up belt is controlled effectively; and, since the size A1 and the angle alpha in the trapezoid projection of the made-up belt are the same as the size A1 and the angle alpha of a trapezoid projection of a finished product, so problems generated because of excessive partial working rate at junctions of thin and thick materials are solved and the rolling process is stable and reliable.

Description

A kind of control device of stable rolling

Technical field

The utility model relates to a kind of control device of band stable rolling, relates in particular to the control device of odd-shaped cross section band stable rolling.

Background technology

The section that is used as the blaster fuse frame material-special-shaped copper alloy band of power tube in the semi-conductor discrete device is formed by thin, thick two kinds of specifications usually; Thin material connects for lead-in wire is used for circuit, thick material supporting chip and heat radiation, and its common section is seen Fig. 6; Be tee-section; Middle for thick material is a trapezoidal ridge, two limits are the thin material of equivalent size, in order to satisfy the requirement of high velocity ram machine mould to the framework punching out; Dimensional tolerance, lateral bending, residualinternal stress to irregular belt material all have very strict specification requirement, and the processing of irregular belt material generally is divided into two processes:

1, the thick moulding of special-shaped made-up belt

2, the finish rolling moulding of abnormity band

What the finish rolling moulding of common abnormity band was adopted is the method (see figure 1) of groove rolling; Sequence number 1 is a concave roll; Sequence number 2 is flat rolls, and sequence number 3 is that trough of belt is led a roller, and the pass on the concave roll is trapezoidal identical with the thick material of finished product; And the trapezoidal trapezoidal (see figure 2) that is greater than the thick material of finished product of the thick material of made-up belt; This is because the influence of special-shaped material various factors when rolling, and the centering of thread such as guide device is bad, inconsistent, variation of lubricating status of roll roll surface roughness, the variation of roll gap, the inhomogeneous deformation when section is rolling or the like, all can make band relative roll pass center when rolling produce move left and right; Though guide device is arranged; But because of leading just point and far away from rolling district that the position contact with band, so the trapezoidal size of the thick material of made-up belt is trapezoidal imperfect of thick material when if not enough words will produce the finish rolling moulding, but the thick material of made-up belt trapezoidal cross conference cause thick, to approach the partial operation rate of expecting intersection excessive and cause:

1, produce the local residualinternal stress of band, deform when making the material punching out,

2, the material local surfaces is impaired, and roughness is overproof,

3, the thin material dimension overproof of thick, thin material intersection,

4, the band lateral bending is overproof, makes the material can't be through diel.

The utility model content

The purpose of the utility model is exactly the control device of a kind of stable rolling that provides in order to overcome the weak point that above-mentioned prior art exists.

The purpose of the utility model can realize through following technical scheme: see Fig. 3; This device comprises that concave roll 1, flat roll 2, trough of belt lead a roller 3, flatly lead a roller 4, T shape band 5, lead a lowering or hoisting gear 6, lead a level(l)ing device 7; Described trough of belt leads a roller 3, flat lead a roller 4, T shape band 5, lead a lowering or hoisting gear 6, lead a level(l)ing device 7 has formed guide device; Grooved hole on the described concave roll 1 and the trapezoidal protuberance shape of finished product kissing; Described trough of belt is led grooved hole and the trapezoidal protuberance shape of the made-up belt kissing on the roller 3, and A1 size and the identical (see figure 7) of α angle in A1 size in the trapezoidal protuberance of described made-up belt and α angle and the trapezoidal protuberance of finished product are describedly led lifting and the decline that a lowering or hoisting gear 6 is used to lead the position; Guide device is positioned at the horizontal level (see figure 3) when wearing band; Guide device progressively promotes when rolling, and produces the grooved hole formation segmental arc that fits tightly (seeing Fig. 4,5) that tension force makes trapezoidal protuberance of made-up belt and concave roll 1, the described level(l)ing device 7 of leading; Be used for minor levels regulate made-up belt center and roll pass center to neutrality; Because the grooved hole of trapezoidal protuberance and concave roll 1 forms a segmental arc that fits tightly and is close to rolling district, the very effective move left and right of controlling made-up belt is in addition owing to the A1 size in the trapezoidal protuberance of made-up belt and α angle are identical with A1 size and α angle in the trapezoidal protuberance of finished product; Avoided factor thick, the excessive generation of thin material intersection partial operation rate, made the operation of rolling reliable and stable.

This utility model compared with prior art, useful effect is:

1, special-shaped rolling time distortion evenly, residualinternal stress reduces.

2, the strip surface roughness is improved.

3, the band lateral bending reduces.

4, rolling stablize easy to control.

The specific embodiment

Below be the embodiment that combines accompanying drawing to be done, with further elaboration the utility model according to the utility model technical scheme.

See Fig. 6, the thin material thickness t 1=0.38mm of finished product T shape band, thick material thickness T 1=1.27mm, A1=27mm; α≤5 °, B1=65.8mm, among Fig. 7, the thin material of made-up belt thickness t 2=0.53mm; Thick material thickness T 2=1.77mm, A1=27mm, α≤5 °, B2=76mm; Concave roll diameter d=200mm leads a roller diameter d=60mm, sees that Fig. 3 wears band and the time leads the position and be positioned at horizontal level, when rolling through leading a lowering or hoisting gear; Leads the position and progressively promote, and the grooved hole that produces trapezoidal protuberance that tension force makes made-up belt and concave roll 1 forms a segmental arc that fits tightly (seeing Fig. 4,5), a described level(l)ing device of leading, be used for minor levels adjusting made-up belt center and roll pass center to neutrality; Described hole shape roll, can be installed in flat roll above, also can be installed in flat roll below, when below being installed in flat roll; Trough of belt is led a roller and is led below the roller flat, this moment T shape band convex surface down, this situation is still at the protection domain of this patent.
