Abstract

The utility model relates to a traction driving wheel, particularly a traction driving wheel used for a wire material straightener, which is composed of a wheel cover, a wheel core, and a ferrule; a groove which can be passed through by the wire material is arranged on the ferrule. Because a three-part structure is adopted, only the ferrule needs to be changed after the abrasion of the groove, and a whole traction wheel needs not to be changed like the conventional traction driving wheels. The utility model has the advantages of low cost of straightening and traction.

Description

The traction drive wheel that straightener is used

The utility model relates to a kind of traction drive wheel, particularly the traction drive wheel of wire rod straightener.

Wire rods such as reinforcing bar need could normally to use after the straightening, straightener commonly used, respectively have a pair of mutually tangent traction drive wheel to be positioned at before and after the straightening part, reinforcing bar is delivered to the straightening part by traction drive wheel, by another traction drive wheel traction output is waited to shear again after the straightening or stand-by.Traction drive wheel commonly used is a complete real core wheel, on side by side multiply groove is arranged, when passing for wire rod, uses groove, because it is traction drive wheel is undertaken the heavy burden of traction, stressed easy to wear, article one, after groove is worn, another groove can be used instead, after all groove part wearing and tearing, just whole traction wheel must be changed, traction wheel is the easy consumption material, frequently changes traction wheel and makes the straightening cost can not be in any more.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of replacement cost traction drive wheel that low straightener is used is provided.

The technical solution of the utility model is achieved in that

Traction drive wheel is by wheel cap, core wheel, lasso three parts are formed, core wheel is the two-stage truncated conical shape of convex, the round platform diameter in the core wheel outside is big, inboard round platform diameter is little, lasso is a graphic structure, outer figure surface is fluted, and inner ring diameter is identical with the overall diameter of the inboard round platform of core wheel, and lasso is enclosed within on the inboard round platform of core wheel, wheel cap covers in the inboard round platform of core wheel outside, wheel cap is with the round platform clamping collar in the core wheel outside, and there is through hole the centre of core wheel and wheel cap, and traction drive wheel is installed in the rotating shaft of straightener by through hole.

The groove of lasso contacts with reinforcing bar, all after the stressed wearing and tearing of groove, only need open wheel cap, and the lasso that more renews get final product, need not resemble traction drive wheel that common straightener uses after groove damages, must the whole traction wheel of replacing.Because the utility model only need be changed lasso, and keep wheel cap and core wheel, changed whole traction drive wheel relatively in the past, use the utility model can reduce the cost of straightening and traction.

Accompanying drawing 1 is the utility model structural representation.

Below in conjunction with description of drawings the utility model.

Embodiment 1: traction drive wheel is by wheel cap 1, core wheel 2, lasso 3 three parts are formed, core wheel 2 is the two-stage truncated conical shape of convex, the round platform diameter in core wheel 2 outsides is big, inboard round platform diameter is little, lasso 3 is a cast structural, surface, outer ring fluted 4, inner ring diameter is identical with the overall diameter of the round platform of core wheel 2 inboards, lasso 3 is enclosed within on the round platform of core wheel 2 inboards, wheel cap 1 covers the round platform outside in core wheel 2 inboards, wheel cap 1 is with the round platform clamping collar 3 in core wheel 2 outsides, and core wheel 2 has through hole with the centre of wheel cap 1, and traction drive wheel is installed in the rotating shaft 5 of straightener by through hole.When core wheel 2 rotated with rotating shaft 5, clamped lasso 3 also rotated with core wheel 2.

Motor-driven straightening part and rotating shaft 5 motions and rotation, the traction transmission occurs in pairs, every pair of tangent contact of traction drive wheel, because the outer ring 3 of two traction drive wheels of existence of groove 4 forms passage on contact-making surface, passage has squeezing action to wire rod 6, wire rod 6 moves forward by the rolling of passage with traction drive wheel, finishes the program of traction.
