Abstract

The utility model discloses a middle roller of a straightening unit for a stretch-bending straightening machine, wherein the roller surface of the middle roller (2) is equipped with an oil guiding groove (3). The oil guiding groove extending from the middle portion of the middle roller to the two ends thereof is terminated at the edges of the oil swing grooves (1) at both ends of the roller surface. The oil guiding groove is spirally distributed on the roller surface of the middle roller. The thin oil containing impurities sprayed on strips flows toward the oil swing grooves at both ends of the roller surface along the roller surface of the spiral oil guiding groove. The smoothness of the roller surface and the roller type can be ensured for a long time due to the radial flow of the thin oil. Therefore, the straightening effect of the strips is ideal and the surface smoothness thereof reaches the standard.

Description

The intermediate calender rolls of aligning unit in a kind of stretch-bending straightening unit

Technical field

The utility model includes non-ferrous metal stretch-bending straightening set, is specifically related to a kind of intermediate calender rolls that is used on the non-ferrous metal stretch-bending straightening unit aligning unit.

Background technology

There is the band of a large amount of thin oil spray lubrications in the smoothing roll portion of fastening of aligning unit in the stretch-bending straightening unit, band is when aligning passes through between the intermediate calender rolls of smoothing roll system and working roll, because the gap is very little and all be elongated roll surface structure between intermediate calender rolls and the working roll, retain greasy dirt impurity between two rollers easily, greasy dirt impurity is piled up for a long time on roller and is influenced roll surface fineness and roll shape, cause the strip straightening effect undesirable, strip surface fineness is not up to standard.

Summary of the invention

In order to address the above problem, the utility model proposes a kind of novel aligning unit intermediate calender rolls structure, solve greasy dirt impurity accumulation problem on the roll surface.

In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:

The intermediate calender rolls of aligning of the present utility model unit is processed oil guide groove on the intermediate calender rolls roll surface, oil guide groove is extended to two ends from the middle part of intermediate calender rolls, ends at the roll surface two ends and gets rid of the oil groove edge.

Be better implement the invention, described oil guide groove shape in the shape of a spiral is distributed on the roll surface.

Be better implement the invention, described oil guide groove has circular-arc groove.

Because adopt aforesaid technical scheme, the utility model produces following good effect:

1, roll surface processing and the elongated oil guide groove of roller, oil guide groove is extended to two ends from the roller middle part, end at the roll surface two ends and get rid of the oil groove edge, and shape is distributed on the roll surface in the shape of a spiral, and Oil Guide is effective.

2, the thin oil band that sprays on the band impurity, flows to the roll surface two ends along the helical form oil guide groove of roll surface and gets rid of oil groove, radially flows down, and result of use is good.

Description of drawings

Fig. 1 is the structural representation of the intermediate calender rolls of the utility model band oil guide groove;

Fig. 2 is the A-A cutaway view of Fig. 1;

Among the figure: 1, get rid of oil groove; 2, intermediate calender rolls; 3, oil guide groove; 4, groove.

The specific embodiment

In conjunction with Fig. 1, aligning of the present utility model unit intermediate calender rolls is that oil guide groove 3 is extended to two ends from intermediate calender rolls 2 middle parts, ends at the roll surface two ends and gets rid of oil groove 1 edge in processing of intermediate calender rolls 2 roll surfaces and the elongated helical form oil guide groove 3 of roller, and shape is distributed on the roll surface in the shape of a spiral.

In conjunction with Fig. 2, the thin oil band that sprays on the band impurity, what flow to the roll surface two ends along roll surface helical form oil guide groove 3 from circular-arc groove 4 gets rid of oil groove 1, along under the roller radial flow, make roll surface fineness and roll shape can obtain the assurance of long period, thereby make strip straightening satisfactory for result, strip surface fineness is up to standard.

Claims
