Abstract

The utility model provides a guide sleeve (100) which comprises a main body (10) and a convex ring portion (20) annularly distributed outside the main body (10). The main body (10) longitudinally extends, and a hollow cylindrical cavity body (11) is arranged in the main body (10). A plurality of through holes (201) are annularly distributed in the convex ring portion (20), step holes (101) are respectively arranged at two ends of the main body (10), semi-blind holes (102) are oppositely arranged in the main body (10) at the positions of the step holes (101), and internal threads are arranged on the inner walls of the semi-blind holes (102). Due to the facts that the step holes are respectively arranged at two ends of the main body, semi-blind holes are oppositely arranged in the step holes, and internal threads are arranged on the inner walls of the semi-blind holes, the guide sleeve can be reliably clamped with a column through the threads, clamp connection firmness between the column and the guide sleeve is improved, and running stability and safety of the whole longitudinal shearing machine set is improved.

Description

A kind of fairlead

Technical field

The utility model relates to a kind of field of mechanical technique, relates in particular to employed a kind of fairlead in the slitter.

Background technology

Slitter claims again slitting line, slitter, and banding machine is a kind of address of metal cutting apparatus.It is applicable to carry out the longitudinal shear work of metal belting, and the coiling again of the fillet after will cutting.It possesses easy to operate, the characteristics such as cut quality is high, stock utilization is high, cutting speed stepless speed regulation.Its groundwork step by uncoiling, unreel, draw anticipate position, itemize slitting, batch, rolling etc. forms.Usually the suitable material of slitter comprises tinplate, silicon steel sheet, aluminium strip, copper, corrosion resistant plate, galvanized sheet etc.In numerous industries, be used widely, comprise transformer, motor, household electrical appliances, automobile, building materials, packaging industry etc.

Fairlead is a kind of parts that often use in the slitting line, the use that complements one another of its main and column.Column may extend into fairlead inside, and the fixing column.But, fairlead of the prior art in use, the clamping between column and the fairlead is not very firm, column and fairlead easily occurs loosening phenomenon occurs, thereby have influence on stability and the security of the operation of whole slitting line.

In view of this, be necessary fairlead of the prior art is improved, to address the above problem.

The utility model content

The purpose of this utility model is to provide a kind of fairlead, and it can improve the firmness of the clamping between column and the fairlead, thereby improves stability and the security of the operation of whole slitting line.

For achieving the above object, the utility model provides a kind of fairlead, comprising: be that lengthwise extends and innerly be provided with the body of hollow cylindrical cavity and be periphery in the projecting ring section of described body exterior, and some through holes that are periphery on the described projecting ring section,

The end, two ends of described body arranges respectively a stepped hole, and subtend arranges half-blind hole in the body at described stepped hole place, on the described half-blind hole inwall internal thread is set.

As further improvement of the utility model, described projecting ring section and body are welded and fixed.

As further improvement of the utility model, the internal diameter of described stepped hole is 30mm.

As further improvement of the utility model, the internal diameter of the circular cylindrical cavity of described body is 28mm.

Compared with prior art, the beneficial effects of the utility model are: by the end, two ends at body one stepped hole is set respectively, subtend arranges half-blind hole in the described stepped hole, on the described half-blind hole inwall internal thread is set, can realize by this screw thread the reliable fixing of fairlead and column, improve the firmness of the clamping between column and the fairlead, thereby improve stability and the security of the operation of whole slitting line.

Description of drawings

Fig. 1 is the axial cutaway view in a kind of fairlead one specific embodiment of the utility model;

Fig. 2 is the side view of the fairlead shown in Fig. 1;

Fig. 3 is the axial cutaway view after the fairlead shown in Fig. 1 and the mutual clamping of column.

The specific embodiment

Below in conjunction with each embodiment shown in the drawings the utility model is elaborated; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skills all belong within the protection domain of the present utility model according to these embodiment institute work energy, method or structural equivalent transformation or alternative.

Please refer to the drawing 1 is with shown in Figure 2, in the present embodiment, a kind of fairlead 100 comprises: be that lengthwise extends and innerly be provided with the body 10 of hollow cylindrical cavity 11 and be periphery in the projecting ring section 20 of described body 10 outsides, some through holes 201 are periphery on the described projecting ring section 20.

The end, two ends of described body 10 arranges respectively a stepped hole 101, and subtend arranges half-blind hole 102 in the body 10 at described stepped hole 101 places, on described half-blind hole 102 inwalls internal thread is set.

Concrete, described projecting ring section 20 is welded and fixed with body 10.The internal diameter of described stepped hole 101 is 30mm.The internal diameter of the circular cylindrical cavity 11 of described body 10 is 28mm.

In conjunction with reference to shown in Figure 3, when column 50 during with this fairlead 100 mutual clamping, column 50 extends in the stepped hole 101, and with body 10 mutual clampings; Extend in the circular blind hole of the formed continuous tool internal thread of half-blind hole (not shown) that another that arrange on half-blind hole 102 and column 50 sidewalls arrange internal thread by bolt 60 simultaneously, thus by bolt 60 with column 50 and body 10 mutual fixings.

Above listed a series of detailed description only is specifying for feasibility embodiment of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent embodiment or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.

To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that do not deviate from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, therefore is intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in the scope.Any Reference numeral in the claim should be considered as limit related claim.
