Description

Wiredrawing step pulley

Technical field

The utility model relates to electric wire and makes the field, relates in particular to the wiredrawing step pulley of making wire rod.

Background technology

Make the wiredrawing step pulley of wire rod at present, mostly being bottom land is flat wiredrawing step pulley, as the disclosed wiredrawing step pulley of Chinese patent CN03217058.0.Because of on processed wire rod is flat wiredrawing step pulley around one group of bottom land, during wire-drawing operation, often produce line ball, cause operation to be interrupted.Said line ball when being exactly operation, is newly introduced the interior line pressure of wire-drawer-tower race on former line in the wire-drawer-tower race, causes former line in the wire-drawer-tower race not lay out, even broken string.

The utility model content

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and not line ball, the wiredrawing step pulley that do not break when a kind of operation is provided.

The purpose of this utility model can reach by following measure:

A kind of wiredrawing step pulley, comprise matrix, gland, be embedded in the wear ring between matrix and the gland, wear ring and matrix and gland constitute groove, and the outer surface of wear ring is positioned at bottom land, the outer surface of wear ring has tapering, and described tapering is in 0.05 ° to 5 ° scope.

Described tapering is 1 °.

The bottom surface of described groove and side are that circular arc is excessive.

Described groove has 4, degree of depth difference, and corresponding wear ring also has 4.

Described matrix is the combination matrix of mechanical connection.

Described wear ring is the wear ring that ceramic material is made.

Described wear ring and gland are an integral body made from high-abrasive material.

Because of the utility model is that wire rod is had in the groove of tapering around the wiredrawing step pulley bottom, from the big end of diameter around going into, an end little from diameter lays out, during operation, because the tapering effect of bottom land, also produce wire rod in the groove and drive gesture to what the little end of groove interior diameter moved, thereby reach a balance, coiling in the groove is not promptly moved to the big end of diameter, does not move to the little end of diameter yet, does not produce line ball, broken string.

The specific embodiment

Fig. 1 shows first embodiment of the present utility model.

Wiredrawing step pulley 100, comprise matrix 101, gland 102, be embedded in the wear ring 103 between matrix 101 and the gland 102, wear ring 103 constitutes groove with matrix 101 and gland 102, the outer surface of wear ring 103 is positioned at bottom land, and the outer surface of wear ring 103 has tapering, and described tapering is 1 °, the bottom surface of described groove and side are that circular arc is excessive, described groove has four, degree of depth difference, and corresponding wear ring 103 also has four.The combination matrix that described matrix 101 is mechanical connections, preceding segment body 1011 is combined into into matrix 101 with back segment body 1012 by screw 1013, and matrix 101 is provided with installing hole 1014, and hole 1014 is provided with keyway 1015.Described wear ring 103 is wear rings that ceramic material is made.Had in the groove of tapering around wiredrawing step pulley bottom by the backguy material during wiredrawing step pulley 100 operations, around going into, an end little from diameter lays out from the big end of diameter.Because the tapering effect of bottom land, also produce wire rod in the groove and drive gesture, thereby reach a balance to what the little end of groove interior diameter moved, the coiling in the groove is not promptly moved to the big end of diameter, does not move to the little end of diameter yet, does not produce line ball, broken string.

Fig. 2 shows second embodiment of the present utility model.

Wiredrawing step pulley 200, comprise matrix 201, gland 202, be embedded in the wear ring 203 between matrix 201 and the gland 202, wear ring 203 constitutes groove with matrix 201 and gland 202, the outer surface of wear ring 203 is positioned at bottom land, the outer surface of wear ring 203 has tapering, and described tapering is 0.05 °, and described groove has four, degree of depth difference, corresponding wear ring 203 also has four.Matrix 201 is provided with installing hole 2014, and hole 2014 is provided with keyway 2015.Described wear ring 203 is wear rings that Hardmetal materials is made.Had in the groove of tapering around wiredrawing step pulley bottom by the backguy material during wiredrawing step pulley 200 operations, around going into, an end little from diameter lays out from the big end of diameter.Because the tapering effect of bottom land, also produce wire rod in the groove and drive gesture, thereby reach a balance to what the little end of groove interior diameter moved, the coiling in the groove is not promptly moved to the big end of diameter, does not move to the little end of diameter yet, does not produce line ball, broken string.

Fig. 3 shows the 3rd embodiment of the present utility model.

Wiredrawing step pulley 300 comprises matrix 301, is embedded in the wear ring 103 on the matrix 101, and the cross section of wear ring 103 is " L " shapes, constitutes groove with matrix 301.The outer surface of wear ring 303 has tapering, and described tapering is 5 °, and described groove has four, degree of depth difference, and corresponding wear ring 303 also has four.The combination matrix that described matrix 301 is mechanical connections, preceding segment body 3011 is combined into into matrix 301 with back segment body 3012 by screw 3013, and matrix 301 is provided with installing hole 3014, and hole 3014 is provided with keyway 3015.Described wear ring 303 is wear rings that ceramic material is made.Had in the groove of tapering around wiredrawing step pulley bottom by the backguy material during wiredrawing step pulley 300 operations, around going into, an end little from diameter lays out from the big end of diameter.Because the tapering effect of bottom land, also produce wire rod in the groove and drive gesture, thereby reach a balance to what the little end of groove interior diameter moved, the coiling in the groove is not promptly moved to the big end of diameter, does not move to the little end of diameter yet, does not produce line ball, broken string.
