Abstract
The utility model relates to a novel recoiling machine pinch roll, which comprises an upper pinch roll and a lower pinch roll, and is characterized in that the upper pinch roll and the lower pinch roll respectively uses a sine roll type, which is a negative convexity type. The novel recoiling machine pinch roll has reasonable structure design, can increase recoiling quality in a certain degree, reduces the abrasion of the pinch roll, increases the production consistency and the stability of strip steel, and prolongs the service life of the pinch roll.
Description
Technical field
The utility model relates to a kind of coiling machine equipment, particularly relates to a kind of novel coiling machine pinch roll.
Background technology
In course of hot rolling, the band steel goes out inevitably inclined to one side DS of finish rolling head or WS, and both monolateral wave or bilateral wave appearred in camber, and also there is this type of phenomenon in afterbody after throwing steel, the control of scroll end to end that influence is batched.When the band steel existed wedge shape big, coiling clamp roller was that plain-barreled roll easily causes the band steel sideslip of nipping, and causes the roller eccentric wear to decrease.Batch in the process at hot-strip, because there is camber in band steel toe tail and is with convexity rolling, often have the bad problem of batching in coiling process, influence band coil of strip shape quality seriously causes accidents such as steel-fastening, influences the stability of producing.In actual production, because influence with factors such as steel transverse temperature inequality, band gad shapes, and be subjected to the influence of planishing roll type wearing and tearing, there is thickness difference in band steel cross section, especially in finishing roll and coiling clamp roller latter stage, tend to the bad phenomenon of scroll occur batching, thereby reduced the scroll quality.Pinch roll is frayed serious, has greatly influenced pinch roll service life.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, novel coiling machine pinch roll easy to use.
In order to address the above problem, the utility model by the following technical solutions:
A kind of novel coiling machine pinch roll comprises top pinch roll and bottom pinch roll, and top pinch roll and bottom pinch roll adopt sinusoidal roll shape respectively, promptly adopts negative convexity roll shape.
The negative convex value of top pinch roll and bottom pinch roll is 50～100 μ m.
The little 20 μ m of the radius of the radius ratio top pinch roll of bottom pinch roll.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model novel structure, the pinch roll roll shape plays correction effect to a certain degree, effectively slowed down because the harmful effect that band steel toe afterbody camber brings to coiling process has improved the scroll quality to a certain extent, thereby improved the production continuity and the stability of band steel.
2, the utility model roll design can effectively be slowed down the wearing and tearing of pinch roll, prolongs the life cycle of coiling machine, thereby has improved the performance of enterprises.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of novel coiling machine pinch roll as shown in Figure 1, comprises top pinch roll 1 and bottom pinch roll 2, and top pinch roll 1 and bottom pinch roll 2 adopt sinusoidal roll shape respectively, promptly adopts negative convexity roll shape.The negative convex value of top pinch roll 1 and bottom pinch roll 2 is 50～100 μ m.The little 20 μ m of the radius of the radius ratio top pinch roll 1 of bottom pinch roll 2.
Embodiment one
A kind of novel coiling machine pinch roll as shown in Figure 1, comprises top pinch roll 1 and bottom pinch roll 2, and top pinch roll 1 and bottom pinch roll 2 adopt sinusoidal roll shape respectively, promptly adopts negative convexity roll shape.The negative convex value of top pinch roll 1 is 60, and the negative convex value of bottom pinch roll 2 is 80.
Claims (3)
1. a novel coiling machine pinch roll comprises top pinch roll and bottom pinch roll, it is characterized in that top pinch roll and bottom pinch roll adopt sinusoidal roll shape respectively, promptly adopts negative convexity roll shape.
2. a kind of novel coiling machine pinch roll according to claim 1 is characterized in that the negative convex value of top pinch roll and bottom pinch roll is 50～100 μ m.
3. a kind of novel coiling machine pinch roll according to claim 2 is characterized in that, the little 20 μ m of the radius of the radius ratio top pinch roll of bottom pinch roll.
