The retraction of the screw nut can be limited through the position limiting part, so the regulation angle range of a straightening roll is effectively and precisely controlled, the occurrence of equipment damage is avoided, and the operation safety is improved.
Description
Technical field
The utility model relates to smoothing roll angle adjustment technology, more particularly, relates to a kind of smoothing roll angular adjustment apparatus of oblique straightener.
Background technology
Cross-roll straightening machine be to bar in rolling, cooling and transportation, the visual plant that the linear arc-shaped bending of bar that causes because of various factors is processed.Cross-roll straightening machine generally is furnished with smoothing roll, be divided into seven rollers, nine rollers, ten rollers etc. (according to the design needs, select suitable smoothing roll quantity for use, upper and lower cross-distribution), operation principle is by the motor outputting power and when passing to smoothing roll by the power transmission shaft transmission, many smoothing rolls make the angle of upper and lower smoothing roll horizontal level change by adjusting upper and lower position pressure reduction, finish the processing to bar rectilinear geometry under the normal temperature.
In order to obtain the correctness of bar rectilinear geometry, the smoothing roll of cross-roll straightening machine is designed to be able to rotate 30 °～50 ° angle in the horizontal direction, thereby adjusts respective angles according to the external diameter difference of being aligned bar.See also shown in Figure 1, smoothing roll level angle adjusting device 10 comprises a pair of screw pair 11, and each screw pair 11 comprises the bearing 112 be located in the housing 111, passes the screw mandrel 113 of bearing 112, the top that is sheathed on the nut 114 on the screw mandrel 113 and is located at nut 114 1 ends.During adjustment, by the screw mandrel 113 that rotates a screw pair 11, drive its nut 114 and shrink cylinder body 1 (see figure 2) that feasible top 115 breaks away from smoothing rolls, the screw mandrel 113 of another screw pair 11 again reverses, make its nut 114 and come directly towards 115 and eject (see figure 3), rotate to drive cylinder body 1, thus the adjustment of realization smoothing roll level angle.
But, because the bar specification of producing is the bar between ∮ 16～∮ 60 at present, corresponding with it as calculated smoothing roll level angle scope is at 35 °～45 °, and in actual production process, the nut 114 flexible limit travels that are, make the actual angle adjustment reach 30 °～50 ° extreme position, cause the universal drive shaft connection corner between smoothing roll and the motor big, in running, universal drive shaft rotates formation centrifugal force and the connecting bolt of shaft coupling between universal drive shaft and the smoothing roll can be cut off, and the heavy wear of universal drive shaft spline, also there are universal drive shaft and straightener column grazing phenomenon, cause the consequence of straightener column wearing and tearing.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of smoothing roll angular adjustment apparatus of oblique straightener, and this adjusting device can be optimized its adjusting range, guarantees the security of operation.
For achieving the above object, the utility model adopts following technical scheme:
The smoothing roll angular adjustment apparatus of this oblique straightener comprises a pair of screw pair, each screw pair comprises housing, screw mandrel, nut and top, be provided with bearing in the housing, screw mandrel passes, nut sleeve is located on the screw mandrel, and the nut front end is located in the top, also is arranged with a limiting component on screw mandrel, limiting component one end and bearing offset, and the other end and nut end offset.
Described limiting component in tubular construction, its length is 37～62mm, external diameter is 80～100mm, internal diameter is 65～75mm.
The end face that described limiting component and bearing offset is and suitable step-like of bearing.
The material of described limiting component is a carbon steel.
In technique scheme, the smoothing roll angular adjustment apparatus of oblique straightener of the present utility model comprises a pair of screw pair, each screw pair comprises housing, screw mandrel, nut and top, on screw mandrel, also be arranged with a limiting component, limiting component one end and bearing offset, and the other end and nut end offset.Can the retraction of nut be limited by this limiting component, thereby effectively and accurately control the adjustment angular range of smoothing roll, avoid generation equipment impaired, improve the security of operation.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
What the smoothing roll angular adjustment apparatus of the oblique straightener that this reality is novel was same as the prior art is, also comprise a pair of screw pair, see also Fig. 4, shown in Figure 5, each screw pair 21 also comprises housing 211, screw mandrel 213, nut 214 and comes directly towards 215, be provided with bearing 212 in the housing 211, screw mandrel 213 passes, and nut 214 is sheathed on the screw mandrel 213, and nut 214 front ends are located in the top.Different is also to be arranged with a limiting component 20 on screw mandrel 213, and limiting component 20 1 ends and bearing 212 offset, and the other end and nut 214 ends offset.Concrete, limiting component 20 in tubular construction, material is a carbon steel, according to the demand of actual straightening roller angle adjustment position, can be 37～62mm with its Design of length, external diameter is 80～100mm, internal diameter is 65～75mm.In addition, the end face that offsets of limiting component 20 and bearing 212 is and suitable step-like of bearing 212.
The use of this adjusting device is as follows: earlier the nut 214 by a screw pair 21 and come directly towards 215 shrink LAP after, its end face contacts and is obstructed with limiting component 20 1 ends, thereby play nut 214 stroke limit effects, also played the spacing of smoothing roll adjustment angle by coming directly towards 215 simultaneously, stretch out by the nut 214 drive tops 215 of another screw pair 21 again, the cylinder body that promotes smoothing roll is rotated to the top 215 with last screw pair and offsets, and this moment, the smoothing roll angle adjustment just put in place.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
