Description
Technical field
The utility model relates to alignment technical field, is specifically related to a kind of alignment combination pinch roller.
Background technology
Man-hour is being added to bar class workpiece, need to carry out alignment to the bar such as steel pole, rod iron, because the hardness of bar is higher, the difficulty of therefore alignment is also higher, and it is also higher to the required precision of alignment, usually adopt the relative platoon of multiple independent pinch rollers in prior art, bar enters alignment between pinch roller, this kind of coalignment complex structure, production cost is high, the workload of again proofreading after there is offset deviation is large, safeguards inconvenient, and alignment less effective.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide the alignment combination pinch roller that a kind of structure is simple, effective to bar alignment, production cost is low.
To achieve these goals, the technical solution of the utility model: a kind of alignment combination pinch roller, include the first pinch roller, the second pinch roller, described first pinch roller is provided with several first annular convex surface, first ring connected in star is provided with between described first annular convex surface, described second pinch roller is provided with several second annular convex surface, and described second annular convex surface is provided with the second annular groove.
Further, many one of the quantity of the first annular convex surface described in the number ratio of described second annular convex surface.
Further, the cross section of described first ring connected in star, the second annular groove is U-shaped, V-arrangement, W shape or circular arc.
Further, described in have the first pinch roller, the center, both sides of the second pinch roller is run through axis hole, described axis hole is provided with mandrel.
Further, described first annular convex surface and described second annular convex surface shift to install.
The beneficial effects of the utility model: overall structure is simple, two pinch roller combinations can complete and carry out alignment to the bar of high rigidity, by controlling the spacing between two pinch rollers, good alignment effect can be reached, debugging is convenient, and production cost is low, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
In figure, the 1, first pinch roller, the 2, second pinch roller, 3, mandrel, the 11, first annular convex surface, the 12, second annular convex surface, 21, first ring connected in star, the 22, second annular groove.
Detailed description of the invention
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of alignment combination pinch roller as shown in Figure 1, include the first pinch roller 1, second pinch roller 2, described first pinch roller 1 is provided with several first annular convex surface 11, first ring connected in star 12 is provided with between described first annular convex surface 11, described second pinch roller 2 is provided with several second annular convex surface 21, described second annular convex surface 21 is provided with the second annular groove 22, many one of the quantity of the first annular convex surface 11 described in the number ratio of described second annular convex surface 21, described first annular convex surface 11 shifts to install with described second annular convex surface 21, described first ring connected in star 12, the cross section of the second annular groove 22 is U-shaped, V-arrangement, W shape or circular arc.The center, both sides of described first pinch roller 1, second pinch roller 2 is run through axis hole, and described axis hole is provided with mandrel 3.
Operation principle of the present utility model is as follows, described first pinch roller 1 and the second pinch roller 2 all rotate to bar direction, bar is extruded, first annular convex surface 11 and the second annular convex surface 21 are by bar alignment, first annular convex surface 11 at interval and the second annular convex surface 21 not easily produce depression or protruding, keep good alignment effect, long service life.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
