Description
Technical field
The utility model belongs to the apparatus field of steel straightener, especially relates to a kind of angle adjustable pinch roll apparatus of precision tube straightener.
Background technology
Precision tube has that bore is less than normal, lighter weight, and the features such as surface quality requirements is strict, have extensive use in nuclear power, chemical industry, automobile and other industries.The precision tube bore that demand is larger is in the market between 18mm ~ 76mm, the finishing operation that aligning operation is produced as production tube, technological requirement " too many levels, soft contact, light landing ", within this type of tubing adopts pinch roll will be walked the wire by strong tubing feeding after afterbody goes out straightener main frame, due to straightener pinch roll angle of the prior art non-adjustable and and aligning central axis, usually can scratch rotating the tubing advanced, and top pinch roll and tubing are thrown off before pinching, do not reach the object suppressing tubing whipping, have a strong impact on the raising of tube straightening precision.The material of pinch roll mostly is the soft materials such as rubber, and its frictional resistance is comparatively large, and wear time is short, and less being not easy to of hardness realizes the compression of pinch roll to steel pipe.Therefore be current raising precision tube recovery rate problem demanding prompt solution to the innovation of updating of precision tube roll straightening equipment.
Summary of the invention
Problem to be solved in the utility model is to provide that a kind of structure is simple, the angle adjustable pinch roll apparatus of firm stable, the precision tube straightener that low to the degree of wear of tubing, flattening precision is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise roll gap adjustment mechanism, upper built-in beam, lower support, upper sliding beam, lower slider beam, top pinch roll, bottom pinch roll, roller seat, support; Described roll gap adjustment organization establishes is in the top of device, described upper sliding beam, lower slider beam distinguish pretension on upper built-in beam, lower support by column, described top pinch roll, bottom pinch roll are installed on the roller seat of sliding beam, lower slider beam respectively, and described support is arranged at the bottommost of device.
Described top pinch roll is axisymmetric hyperboloid stereochemical structure.
Described bottom pinch roll is the cylindrical structure with cornerite.
Described top pinch roll, bottom pinch roll are nylon material.
Described support is rectangular structure.
Owing to adopting technique scheme, roller seat can be rotated around its center by the promotion of hydraulic cylinder, realizes the angular adjustment of pinch roll roll body, with the object meeting stable aligning and pinch.In straightening process, top pinch roll plays compression stabilization, ensures that top pinch roll is consistent with main frame smoothing roll angle in straightening process, avoids the possibility of scratch tube surfaces.Bottom pinch roll be initiatively dodge roller fast, bottom pinch roll, when not pinching, rotates the resistance just overcoming self and rotate.Top pinch roll and bottom pinch roll select hardness and the higher nylon material of tensile strength, compared with other materials, reducing friction resistance while ensureing roll surface hardness is low to the degree of wear of tubing.Adopt above-mentioned pinch roll apparatus to efficiently solve pinch roll to be easy to abrade the problem of body, and the whipping problem of tubing is rectified on backstage.
The beneficial effects of the utility model are: have that structure is simple, firm stable, the advantage that low to the degree of wear of tubing, flattening precision is high.

Detailed description of the invention
As shown in Figure 1, the angle adjustable pinch roll apparatus of a kind of precision tube straightener of the utility model, comprises roll gap adjustment mechanism 1, upper built-in beam 2, lower support 3, upper sliding beam 4, lower slider beam 5, top pinch roll 6, bottom pinch roll 7, roller seat 8, support 9; Described roll gap adjustment mechanism 1 is arranged at the top of device, described upper sliding beam 4, lower slider beam 5 distinguish pretension on upper built-in beam 2, lower support 3 by column, described top pinch roll 6, bottom pinch roll 7 are installed on the roller seat 8 of sliding beam 4, lower slider beam 5 respectively, and described support 9 is arranged at the bottommost of device.Described top pinch roll 6 is axisymmetric hyperboloid stereochemical structure.Described bottom pinch roll 7 is the cylindrical structure with cornerite.Described top pinch roll 6 and bottom pinch roll 7 are nylon material.Described support 9 is rectangular structure.
The course of work of this example: upper sliding beam 4, lower slider beam 5 slide respectively on the column of the upper built-in beam 2 of pretension, lower support 3.The roll gap of upper sliding beam 4 on column between upper and lower slidable adjustment two roll body, i.e. opening degree.Lower slider beam 5 quick sliding under the driving of hydraulic cylinder realizes fast clamp steel pipe.The upper and lower sliding driving device of upper sliding beam 4 is worm-and-wheel gear, worm screw is driven via motor, drive on the rotation limit, screw mandrel limit of sliding beam motion and rise or descending motion, the number of turns rotated by gathering leading screw can control roll gap size accurately, also accurately can provide the deviation in top pinch roll 6 and main frame end roller top roll centre-height simultaneously, namely be equivalent to the recurvation amount accurately controlling pinch roll, achieve the object of stable aligning, improve flattening precision.The upper and lower slip of lower slider beam 5, by two Driven by Hydraulic Cylinder, by driving cylinder design to be the hydraulic cylinder that cylinder end flange connects, reducing equipment center of gravity, being conducive to the rigidity improving lower slider beam 5.Roller seat 8 can be rotated around its center by the promotion of hydraulic cylinder, realizes the angular adjustment of pinch roll roll body.Angle adjusting mechanism, can adapt to steel pipe aligning speed, namely in straightening process, the angle of top pinch roll 6 is consistent with the angle of main frame smoothing roll, at the end of straightening process, the angle of top pinch roll 6 becomes and main frame smoothing roll central axis, immediately to adapt to the requirement of material casting.
Above the angle adjustable pinch roll apparatus of a kind of precision tube straightener provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
