Abstract

The invention relates to a guiding device of a rolling mill. The technical scheme includes that a front guiding roll 2 and a back guiding roll 5 are mounted by using the two edges of the body of a pass roll 4 as locating datum while retaining edges of retaining wheels are respectively matched with the front guiding roll 2 and the back guiding roll 5, so that pass centering precision of the front guiding roll 2, the pass roll 4 and the back guiding roll 5 can be guaranteed by machining precision. When the pass roll 4 is in axial play, the front guiding roll 2 and the back guiding roll 5 can move along with the pass roll 4, and thus, the pass centering precision of the front guiding roll 2, the pass roll 4 and the back guiding roll 5 cannot be affected. In addition, the guiding device of the rolling mill is convenient to mount and is capable of realizing high-precision automatic centering without regulation.

Description

A kind of guide device of milling train

Technical field

The present invention relates to a kind of guide device of milling train, relate in particular to the guide device of rolling special-shaped cross section band and strip rolling mill.

Background technology

The section that is used as the blaster fuse frame material-special-shaped copper alloy belt of power tube in the semi-conductor discrete device is formed by thin, thick two kinds of specifications usually, and thin material is used for circuit for going between and connects thick material supporting chip and heat radiation; Its common section is seen Fig. 1; A is a tee-section among Fig. 1, and the centre is that thick material T two limits are thin material t, and b is a channel section; Middle is thick material T for approaching material t two limits; In order to satisfy high velocity ram machine and packaging technology and transistor electronic component performance, except material has special requirement, dimensional tolerance, surface roughness, hardness and the plate shape of irregular belt material and burr all there is very strict specification requirement in the manufacture process; Fig. 2 is the instance of tee-section specification requirement; The rolling method of the many employings of the processing of irregular belt material, in order to make irregular belt material ability homogeneous deformation when rolling, the hole shape in operation of rolling sprocket bit device and the centering performance of roll hole shape play crucial effects to the quality of product.

The centering of guide device commonly used is adopted the method for manual adjustment more; Find in actual the use that the centering process bothers very much and precision is not enough; Cause band in the roll hole shape, to depart from and cause distortion inhomogeneous; Produce dimensional discrepancy and various blemish to band is scrapped, in addition because the gap of roll bearing also can make band in the roll hole shape, depart from.

Summary of the invention

The object of the invention is exactly a kind of milling train guide device that is used for rolling special-shaped band that provides for the weak point that overcomes above-mentioned prior art existence.

The object of the invention can be realized through following technical scheme: see Fig. 3; This device comprise roll before T shape band 1, roll bit preamble roller 2, flat roll 3, hole shape roll 4, lead a roller 5 after rolling, roll back T shape band 6; Described flat roll 3 is on hole shape roll 4; Described T shape band convex surface passes through between flat roll 3 and hole shape roll 4 down; Describedly roll the entrance side that bit preamble roller 2 is installed in milling train, lead the outlet side that a roller 5 is installed in milling train after described the rolling, the described bit preamble roller 2 that rolls comprises axle 2.1, nut 2.2, bearing 2.3, gear wheel 2.4, flute profile roller 2.5, back-up ring 2.6, circlip for hole 2.7; Described gear wheel 2.4 separates with grooved roller 2.5 usefulness back-up rings 2.6; Each personal bearing 2.3 is fixed on the axle 1, and can rotate the rotation the when rib of gear wheel 2.4 and roll barrel two edge joints touch like this and the rotation mutually noninterfere of grooved roller 2.5 relatively; Lead a roller 5 structures after described the rolling and to roll bit preamble roller 2 identical; Before and after to lead roller be positioning reference with the body of roll two limits of hole shape roll 4 when installing that the rib of gear wheel 2.4 and 5.4 is mated, can guarantee to roll bit preamble roller 2, hole shape roll 4 with the precision of machining like this, lead the accuracy of alignment of the hole shape of a roller 5 after rolling, and when hole shape roll 4 has axial float; Leading a roller 5 after rolling bit preamble roller 2 and rolling can move thereupon, does not influence bit preamble roller 2, hole shape roll 4, leads the accuracy of alignment of the hole shape of a roller 5 after rolling.

This is invented compared with prior art, and useful effect is:

1, guide device automatic centering easy for installation need not to regulate, and accuracy of alignment is high.

2, guide device and roll servo-actuated have overcome the difficult problem that the roll play brings to centering.

3, minimizing is scrapped, and improves the yield rate of product.

The specific embodiment

Below be the embodiment that combines accompanying drawing to do, with further elaboration the present invention according to technical scheme of the present invention.

See that Fig. 6 rolls the thin material thickness t=2.5mm of preceding T shape band 1, thick material thickness T=8.8mm, the thin material thickness t 1=1.3mm of T shape band 6 after rolling; Thick material thickness T 1=4.45mm; On rolling the flute profile roller 2.5 of bit preamble roller 2, according to the size perforate of T shape band 1 before rolling, after rolling, lead on the flute profile roller of a roller 5 according to the size perforate of rolling back T shape band 6, being positioning reference with the body of roll two limits of hole shape roll 4 when a roller installation is led in front and back is mated the rib of gear wheel 2.4 and 5.4; Can guarantee to roll bit preamble roller 2, hole shape roll 4 with the precision of machining like this, lead the accuracy of alignment of the hole shape of a roller 5 after rolling; When hole shape roll 4 has axial float, lead a roller 5 after rolling bit preamble roller 2 and rolling because the effect meeting of rib is moved with hole shape roll 4, do not influence bit preamble roller 2, hole shape roll 4, lead the accuracy of alignment of the hole shape of a roller 5 after rolling; Described hole shape roll 4 can be installed in flat roll 3 below; Also can be installed in flat roll 3 above, in the time of above being installed in flat roll 3, roll bit preamble roller 2 and roll after lead a roller 5 in the above; This moment T shape band convex surface up, this situation is still at the protection domain of this patent.
