Abstract

The utility model discloses a pressed steel joint for a wire rope, comprising a steel joint sleeve (1) and a wire rope (2). The final end of the wire rope is penetrated through the sleeve and is folded into an annular type, and the wire rope is penetrated in the sleeve. The wire rope and the sleeve are pressed in a cold mode into an integration, and the pressed steel joint for the wire rope is smooth, clean and hard. The utility model has the advantages of high reliability, wear-resistance, high temperature-resistance, not being limited by the use condition and occasion, and being used for lifting or banding in each industry.

Description

Pressed steel joint for wire rope

The utility model is a kind of rigging.It relates to a kind of wire rope steel compacting joint, and it can be used for lifting, traction and the colligation of every profession and trade.

Wire rope is when being used for lifting, traction or colligation, terminal all needs to make a kind of joint of ring-type, its traditional practice is to adopt the artificial mode of interting, the not end that is about to rope separates by thigh, be interspersed in again among the rope dried thigh and thigh after being bent into ring-type, and the frictional force between dependence thigh and the thigh, keep not slippage of joint.This interspersed method, working strength of workers is very big, and joint is very infirm, can not bear wire rope pulling force at full capacity, uses and feels unwell entirely, because making is simple, economy is still being used in some occasions.Occurred a kind of aluminum alloy joint in recent years, this joint is the price height not only, and non-refractory, and use occasion is restricted, and is simultaneously not wear-resisting, and not anti-bumping is damaged easily, therefore is difficult for promoting the use of.

The purpose of this utility model just is to overcome above-mentioned shortcoming, and a kind of product of safe and reliable high-intensity wire rope steel joint is provided.

The purpose of this utility model is achieved in that wire rope do not held passes the steel sleeve pipe, is bent into ring-type, in the threading, carries out cold hobbing again, makes it plastic deformation at normal temperatures, and wire rope and steel sleeve pipe are squeezed into solid one.

Because wire rope and steel sleeve pipe are by cold hobbing, plastic deformation at normal temperatures is combined into one.Be full of metal between the thread of wire rope like this, the thread of wire rope all embeds the inwall of steel sleeve pipe fully.This combination, be utilize between sleeve pipe and the wire rope, the frictional force sum between wire rope and the wire rope, be slightly larger than the rupture pull force of wire rope, thereby reaching the disrumpent feelings fag end of wire rope can not skid off from sleeve pipe, sleeve pipe can not break, and is bright and clean hard, uses reliable.Simultaneously, its cost is low, and is high temperature resistant, wear-resistant, not limited by service condition, occasion, is easy to promote the use of.

Further set forth concrete enforcement of the present utility model below in conjunction with accompanying drawing.

Accompanying drawing is a structural representation of the present utility model.

Referring to accompanying drawing, sleeve pipe (1) is the steel metal, low-carbon (LC) Fine Steel Casting iron preferably, for ease of wire rope, preferably earlier it is pressed into flat garden shape, make wire rope (2) just in time pass, to not hold then and be bent into ring-type, from sleeve pipe (1), wear out again, expose some fag ends, they are placed on to withhold carry out cold hobbing in the mould and be integral.In the joint pressing process, flat garden steel bushing at first is out of shape along long axis direction (A-A) and dwindles, continuous increase along with press power, gradually to garden shape transition, when steel bushing narrows down to after wire rope contacts, just dwindle together with wire rope, becket bridle two branch's steel wires are pressed against each other, and finally form the wire rope compound section of an approximate flat garden shape, when the hardness of this compound section during greater than steel bushing, the plastic deformation of steel bushing material, in steel bushing inwall and wire rope compound section at the interface, the steel bushing material be squeezed into strand wire and strand between, silk with thread between the gap, make steel bushing and wire rope be compacted into one, thereby constitute reliable connection the between steel bushing and the wire rope.On compacting mechanism, the joint press forming is to adopt cold extruding technique, and shaping stage is forward extrusion, and after-stage is a lateral extrusion, so the extruding overall process is forward and radially mixes extruding.

Claims

1, a kind of wire rope steel compacting joint comprises sleeve pipe (1) and wire rope (2), and it is characterized in that: sleeve pipe (1) is the steel metal, and the not end of wire rope (2) passes steel sleeve pipe (1) and is bent into ring-type, in the threading (1), is integral through cold hobbing again.

2, joint as claimed in claim 1 is characterized in that: sleeve pipe (1) is the low-carbon (LC) Fine Steel Casting iron.
