Abstract
The utility model relates to a belted steel draws machine of rectifying, include along bending roll, leveling roller and the export slewing rollers of the overall arrangement of belted steel direction of delivery, the export slewing rollers are 995mm with leveling roller centre -to -centre spacing, and the export slewing rollers are global, and the leveling roller is global goes up the edge along being less than down, and it is global down along being 20~25mm with the global vertical interval that goes up the edge of leveling roller to export slewing rollers. Further, between bending roll and the leveling roller, slewing rollers in the middle of still being provided with, middle slewing rollers are provided with doctor's sword respectively with the export slewing rollers, and the global of its place roller is pressed close to to doctor's sword d cutting edge. This belted steel draws machine of rectifying, the curved problem of the C type that appears can be reduced in the position that sets up of having improved the export slewing rollers when belted steel is corrected, and the belted steel that is particularly useful for the heavy gauge is corrected, increase the preferred scheme of doctor's sword and jetting device, can avoid the iron oxide dust of roll surface adhesion to lead to the fact the influence to the belted steel quality.
Description
Technical field
The utility model relates to output strip line, is particularly with steel withdrawal straightening machine.
Background technology
Output strip line is provided with withdrawal straightening machine, and its function is to apply flexural deformation and stretcher strain to the band steel run, and realizes the object of band steel aligning and scale on surface scale breading.Withdrawal straightening machine includes bending roll and smoothing roll along being with steel throughput direction layout, is provided with outlet turning roller after smoothing roll.Its outlet turning roller of existing withdrawal straightening machine is all arranged near smoothing roll, outlet turning roller and smoothing roll centre-to-centre spacing are usually at about 310mm, under outlet turning roller side face, edge is lower than edge on smoothing roll side face, and the vertical spacing in two faces is usually at about 50mm, such structural design compares and is applicable to thin tape steel.
Along with production technology progress, the steel plate demand of heavy thickness gets more and more, and the withdrawal straightening machine of this conventional design is when processing Deformation in thick, and the band steel of such as more than 2.5mm, often can not obtain good rectification effect, the problem especially severe that band steel C type is curved.In addition, the easy bonding turning roll surface of the brown iron oxide that belt steel surface comes off, piles up gradually after increasing and can cause impression at belt steel surface, affect product surface quality.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of band steel withdrawal straightening machine, can avoid the curved problem of C type occurred when being with steel to correct, the band steel being particularly useful for heavy thickness is corrected.
The utility model solves the technical scheme that its technical problem adopts:
Band steel withdrawal straightening machine, comprise along the bending roll being with steel throughput direction layout, smoothing roll and outlet turning roller, described outlet turning roller and smoothing roll centre-to-centre spacing are 995mm, under outlet turning roller side face, edge is lower than edge on smoothing roll side face, and under outlet turning roller side face, edge is 20 ~ 25mm with the vertical spacing on edge on smoothing roll side face.
Further, between bending roll and smoothing roll, also be provided with middle slewing rollers, described middle slewing rollers and outlet turning roller are respectively arranged with doctor's cutter, doctor's cutter is also provided with the control air source equipment stretching out for controlling its blade or retract, when doctor's cutter blade stretches out, blade presses close to the side face of its place roller.
Further, described bending roll comprises top roll box and roll box, and described top roll box and roll box are respectively arranged with blowing device, and described blowing device emission direction points to the backing roll roll surface of roller box inside.
The beneficial effects of the utility model are: this band steel withdrawal straightening machine, improves the setting position of outlet turning roller, and can reduce the curved problem of C type occurred when band steel is corrected, the band steel being particularly useful for heavy thickness is corrected; Increase the preferred version of doctor's cutter and blowing device, the iron oxide dust of roll surface adhesion can be avoided to impact strip quality.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of embodiment of band steel withdrawal straightening machine of the present utility model;
In figure, Reference numeral is: bending roll 1, smoothing roll 2, middle slewing rollers 31, outlet turning roller 32, doctor's cutter 4, blowing device 5.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Band steel withdrawal straightening machine, comprise along the bending roll 1 being with steel throughput direction layout, smoothing roll 2 and outlet turning roller 32, described outlet turning roller 32 is 995mm with smoothing roll 2 centre-to-centre spacing, under outlet turning roller 32 side face, edge is lower than edge on smoothing roll 2 side face, and under outlet turning roller 32 side face, edge is 20 ~ 25mm with the vertical spacing on edge on smoothing roll 2 side face.
As shown in Figure 1: this band steel withdrawal straightening machine, have bending roll 1, smoothing roll 2 and outlet turning roller 32 along band steel throughput direction layout, wherein bending roll 1 can be have two covers and edge band steel throughput direction layout usually.
Relative to traditional mechanism, outlet turning roller 32 and smoothing roll 2 centre-to-centre spacing of mechanism are 995mm, it has larger spacing, and along also reducing with the vertical spacing on edge on smoothing roll 2 side face under outlet turning roller 32 side face, namely be that the bending deformation quantity of band steel is reduced, according to different belt steel thickness, under outlet turning roller 32 side face, edge can be 20 ~ 25mm with the vertical spacing on edge on smoothing roll 2 side face.
When band steel exports from withdrawal straightening machine outlet turning roller 32, its flexural deformation diminishes, and this is conducive to the stress of cancellation band steel in correcting process, avoids band steel to occur the problem that C type is curved, especially be the heavy thickness band steel of more than 2.5mm for thickness, it is more obvious that it improves effect.
In order to eliminate the impact of oxide powder on belt steel surface, preferably, can be between bending roll 1 and smoothing roll 2, also be provided with middle slewing rollers 31, described middle slewing rollers 31 and outlet turning roller 32 are respectively arranged with doctor's cutter 4, doctor's cutter 4 is also provided with the control air source equipment stretching out for controlling its blade or retract, and when doctor's cutter 4 blade stretches out, blade presses close to the side face of its place roller.
Doctor's cutter 4 is a kind of devices utilizing air pressure control blade to stretch out or retract, its blade presses close to the side face of its place roller, may be used for the contamination of striking off roller surface, adopt this preferred embodiment, utilize control air source equipment, intermittent control blade stretches out, and regularly can strike off the accumulation powder on roller surface, prevents from causing impression at belt steel surface.
Preferred further, can also be that described bending roll 1 comprises top roll box and roll box, described top roll box and roll box be respectively arranged with blowing device 5, and described blowing device 5 emission direction points to the backing roll roll surface of roller box inside.
As shown in Figure 1, in the end the top roll box of a set of bending roll 1 and roll box place arrange blowing device 5, the pressed gas of its ejection can blow off the croci of roller box interior support roller roll surface, reduces the probability that follow-up roll surface piles up powder further, prevents from affecting strip surface quality.
