Abstract
The utility model relates to a straightening machine, in particular to a two-roller straightening machine upper roller adjusting mechanism for steel pipe production. The two-roller straightening machine upper roller adjusting mechanism mainly solves the technical problem that in the prior art, a straightening roller of an existing straightening machine is complex in structure, miscellaneous in adjustment, over-large or over-small in adjusting range, accordingly low in straightening efficiency and the like. The two-roller straightening machine upper roller adjusting mechanism comprises a straightening roller body (1), and is characterized in that a swing shaft (2) is connected to the straightening roller body (1) in a penetrated mode, a straightening roller support (3) is connected to the swing shaft (2), a fixing block (4) is fixed in the middle of the straightening roller support (3), a moving base (5) is arranged on the upper surface of the straightening roller support (3), the fixing block (4) is embedded in the moving base (5), a swing arm (6) is further hinged to the end portion of the straightening roller support (3), and the other end of the swing arm (6) is connected to the moving base (5).
Description
Technical field
The utility model relates to a kind of two-roll reeler, especially relates to a kind of two-roll reeler top roll guiding mechanism for steel pipe's production.
Background technology
Bar, tubing, in manufacturing process, owing to being subject to the impact of various factors, often produce plastic deformation multi-form, in various degree, produce the form errors such as many disadvantages and linearity, circularity.Chinese patent discloses a kind of two-roll reeler pre-rotation input mechanism (Granted publication number: CN 202779511 U), it comprises frame, frame front side is provided with lower roller mechanism and upper roller mechanism, lower roller mechanism and upper roller mechanism are arranged symmetrically with up and down, lower roller mechanism comprises lower roll lifting mechanism, lower roll lifting mechanism top is provided with bottom pinch roll, between lower roll lifting mechanism and bottom pinch roll, be provided with lower roll angle-adjusting mechanism, on lower roll lifting mechanism, be provided with lifting adjustment mechanism of lower, upper roller mechanism comprises top roll elevating mechanism, top roll elevating mechanism below is provided with top pinch roll, between top pinch roll and top roll elevating mechanism, be provided with top roll angle-adjusting mechanism, on top roll elevating mechanism, be provided with top roll lift adjustment mechanism.But the smoothing roll structure of this two-roll reeler is comparatively complicated, adjusts comparatively numerous and diverse, and adjusting range be not excessive be exactly too small, thereby it is lower to align efficiency.
Utility model content
The utility model is to provide a kind of two-roll reeler top roll guiding mechanism for steel pipe's production, it is mainly that to solve the smoothing roll structure of the existing two-roll reeler of prior art comparatively complicated, adjust comparatively numerous and diverse, and adjusting range be not excessive be exactly too small, thereby the technical problem of aligning efficiency lower grade.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Two-roll reeler top roll guiding mechanism for steel pipe's production of the present utility model, comprise smoothing roll body, on described smoothing roll body, cross-under has swinging axle, swinging axle is connected with on smoothing roll frame, in the middle of smoothing roll frame, be fixed with fixed block, smoothing roll frame upper surface is provided with Mobile base, and fixed block is embedded in Mobile base, smoothing roll frame end portion is also hinged with swing arm, and the swing arm other end is connected on Mobile base.Swinging axle can swing adjustment after driving by drive unit, thereby smoothing roll can be treated the steel pipe of aligning and carries out straightening processing.Swing arm can be played spacing effect, and when swinging axle swings to a certain degree, swing arm will be limit extremely an angle, thereby prevents that amplitude of fluctuation is excessive.
As preferably, between described swinging axle and smoothing roll frame, be provided with multipair bearing.Swinging axle is more smooth and easy rotatably like this.
As preferably, described smoothing roll frame is provided with oil duct, and it is inner that oil duct is communicated with bearing.By inject grease in oil duct, can play lubrication to parts such as swinging axles.
As preferably, the outer surface of described smoothing roll body is provided with a plurality of rubber projections.Can offer a plurality of pits at the outer surface of smoothing roll body, then rubber projections is pushed in pit and forms and fix, rubber projections can be spacing on smoothing roll by steel pipe, and steel pipe can be aligned in the position limiting like this, and the efficiency of aligning is higher.
As preferably, the amplitude that described swinging axle swings is 16o.Excessive or too small amplitude of fluctuation all can affect the straightening processing to steel pipe.
Therefore, it is spacing that the utility model utilizes swing arm to carry out the angle of smoothing roll, can make steel pipe under best angle, carry out straightening processing, and the efficiency of aligning is higher, simple and reasonable for structure.

Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1.
Parts, position and numbering in figure: smoothing roll body 1, swinging axle 2, smoothing roll frame 3, fixed block 4, Mobile base 5, swing arm 6, bearing 7, oil duct 8, rubber projections 9.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the two-roll reeler top roll guiding mechanism for steel pipe's production of this example, as shown in Figure 1, Figure 2, comprise smoothing roll body 1, the outer surface of smoothing roll body is provided with a plurality of rubber projections 8.On smoothing roll body, cross-under has swinging axle 2, and swinging axle is connected with on smoothing roll frame 3, is fixed with fixed block 4 in the middle of smoothing roll frame, smoothing roll frame upper surface is provided with Mobile base 5, fixed block is embedded in Mobile base, and smoothing roll frame 3 ends are also hinged with swing arm 6, and the swing arm other end is connected on Mobile base 5.Between swinging axle and smoothing roll frame, be provided with multipair bearing 7.Smoothing roll frame is provided with oil duct 8, and oil duct is communicated with bearing 7 inside.The amplitude that swinging axle swings is 16o.
During use, utilize swinging axle 2 smoothing roll body 1 can be adjusted to optimal angle, after smoothing roll body 1 rotates, can carry out straightening processing to steel pipe.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
