Abstract
The utility model provides a guide slot device that sour tandem rolling circle shear slitter edge was carried, include upper portion guide slot that links to each other with the circle shear and the lower part guide slot that links to each other with the scrap cutter. Upper portion guide slot entry and export are straightway, the transition of middle adoption segmental arc. Lower part guide slot entry opening is greater than upper portion guide slot export opening, and the easiliest the lower part guide slot outside riser of wearing and tearing adds the antifriction plate backplate that 1 30mm is thick. The utility model discloses the entry straightway has reduced the stifled limit that the perk of slitter edge head caused, the high -speed stifled limit of strikeing upper portion guide slot emergence bending deformation and causing of slitter edge has been reduced through the segmental arc transition, the wear -resisting backplate of lower part guide slot can effectively reduce the stifled limit that lower part guide slot export is worn and torn and is caused the skew scrap cutter cutting edge of slitter edge and cause, the difficult wearing and tearing of antifriction plate to the installation is changed portably.
Description
Technical field
This utility model is related to the waste selvage conveying device after slitter edge is cut in hot-rolled coil pickling, more particularly to a kind of to connect for acid
Roll the slitter edge guide apparatus of circle shear.
Background technology
Pickling, cold rolling series connection are continuously produced by sour continuous rolling process, greatly improve production efficiency.Due to hot-strip edge
Easily occur while damage while split, Deformation structure, coarse-grain, side drop etc. defect, therefore after pickling, it is cold rolling before need to cut off edge.Trimming sets
Standby to include the devices such as circle shear, guide groove, scrap cutter, for slitter edge is cut off, slitter edge is transported to scrap cutter to circle shear by guide groove, broken
While cut slitter edge is cut off.
Often there is the stifled side phenomenon of slitter edge to circle shear in Jing in process of production, especially ratio occurs in position while welding very big.It is stifled
While having a strong impact on the normal production of sour tandem rolling, mainly there are three types：One is that slitter edge tilts the stifled side caused；Two is high-speed cruising
Slitter edge impacts guide groove, the stifled side for causing slitter edge flexural deformation to be formed；Three is the outer cant board outlet serious wear of guide groove, causes slitter edge
Deviate the stifled side that scrap cutter cutting edge position is formed.
The guide apparatus for being presently used for circle shear and scrap cutter mainly have two types：Split type and monoblock type.
Patent CN201960202U discloses a kind of Split scrapping guide chute of rotary sheared edge, and guide groove is divided by the utility model
For anterior, three part of middle part and rear portion, upper cover plate adopts high-abrasive material, and the outer cant board thickness of lower guide channel most easy to wear is by 30mm
It is changed to 50mm.The utility model can effectively improve the service life of guide groove, reduce steel-fastening number of times, reduce steel-fastening process time.
But the device portal does not design straightway, also no changeover portion, the slitter edge of high-speed cruising are easily tilted, are directly impinged upon
On cover plate, occur bending and deformation and cause stifled side.Although the outer cant board of lower guide channel carries out thickening process, but nothing after serious wear
Method quick-replaceable.Patent CN202726175U discloses a kind of monoblock type transition guide apparatus, and the device equally easily makes slitter edge
There is blastic deformation in guide groove, next to that not making any improvement on the outside of bottom guide groove most easy to wear, after abrasion, change difficult.
Utility model content
This utility model is directed to the deficiencies in the prior art, there is provided a kind of slitter edge guide apparatus for sour tandem rolling circle shear,
Reduce the stifled side probability of sour tandem rolling circle-shear slitter edge.
For solving above-mentioned technical problem, this utility model is adopted the following technical scheme that：
A kind of slitter edge guide apparatus for sour tandem rolling circle shear, including top guide groove and bottom guide groove；Top guide groove with
Circle shear is connected；Bottom guide groove is connected with scrap cutter；Top guide groove upper plate adopts arcuate structure, and entrance is straightway, and centre is adopted
Segmental arc transition is used, is exported as straightway；Entrance opening of the exit opening of top guide groove less than bottom guide groove.
Further, insert on the inside of the outer cant board of the described slitter edge guide apparatus middle and lower part guide groove for sour tandem rolling circle shear
One piece of backplate.
Further, in the described slitter edge guide apparatus for sour tandem rolling circle shear, the thickness of backplate is 30mm.
Further, described slitter edge guide apparatus middle and upper part guide groove upper plate and backplate for sour tandem rolling circle shear are adopted
Use abrasion-resistant stee.
Compared with prior art, this utility model at least has the advantages that：
Upper cover plate straightway entrance can effectively reduce slitter edge head and tilt the stifled side caused；Slitter edge from straightway out after
Steering is seamlessly transitted by segmental arc, impact of the high-speed cruising slitter edge to top guide groove is reduced, slitter edge can be effectively reduced and be existed
The stifled side that top guide groove occurs bending and deformation and causes；Wear plate on the outside of the guide groove of bottom, can effectively reduce bottom guide groove
The stifled side that outlet abrasion causes slitter edge to deviate scrap cutter cutting edge and causes；Wear plate is not easy to wear, can protect guide groove very well,
And it is easy to install replacing.

Specific embodiment
The present invention is described further with reference to embodiment, but embodiment should not be construed as limiting the invention.
As shown in Figure 1, for the slitter edge guide apparatus of sour tandem rolling circle shear, including top guide groove 1 and bottom guide groove 2；On
Portion's guide groove 1 is connected with circle shear 3；Bottom guide groove 2 is connected with scrap cutter 4；Top guide groove upper plate 5 adopts the arcuate structure, entrance to be
Straightway, it is middle to adopt segmental arc transition, export as straightway.The exit opening of top guide groove is opened less than the entrance of bottom guide groove
Mouthful.Upper cover plate straightway entrance can effectively reduce slitter edge head and tilt the stifled side caused；Slitter edge is incorporated into arc by straightway
Shape section, reduces impact of the high-speed cruising slitter edge to top guide groove, can effectively reduce slitter edge and bend change in top guide groove
Shape and the stifled side caused.From Fig. 2 and Fig. 3, on the inside of the outer cant board 6 of the bottom guide groove of side easy to wear, one piece of insertion is wear-resisting
Backplate 7, the thickness of backplate 7 is 30mm, backplate 7 wear and tear after fast changeable.Wear plate on the outside of the guide groove of bottom, can be effective
Reduce the stifled side that guide groove outlet abrasion in bottom causes slitter edge to deviate scrap cutter cutting edge and causes.Top guide groove upper plate 5 and backplate 7 are equal
Using abrasion-resistant stee, remaining position of guide groove adopts Q235 steel.
This utility model is described in detail above in association with accompanying drawing embodiment, those skilled in the art can be according to this reality
Various corresponding changes and deformation are made with new, but these corresponding changes and deformation should all belong to appended by this utility model
