Description
Technical field
The present invention relates to a kind of stainless steel cable and preparation method thereof, more particularly to a kind of major diameter stainless steel cable and its
Production method.
Background technology
Stainless steel cable on the market is divided into 2 kinds at present, and one kind is hot-cast type stainless steel cable, another kind be press type not
Become rusty steel cable;Drag-line below 36 millimeters of diameter is that the stainless steel cable of press type, 36 millimeters of diameter or more is hot-cast type.There is phase
36 millimeters can only be accomplished greatly, and also there are no more than 36 millimeters in actual production by closing the stainless steel cable of standard gauge level pressure
Stainless steel cable can use compression moulding.
In addition, existing press type stainless steel cable(As shown in Figure 1)Conventional crimping mode be upper pushing(Such as Fig. 2 institutes
Show), the steel for wire drawing appearance pressed out in this way is not round enough, and not enough tightly, steel strand wires big 36mm just need 3000 tons of forcing press
It could press solid, the steel strand wires of bigger can not just crimp securely.And crimp head is somewhat flat, and both sides can be upper and lower
The contact surface of mould has two muscle, as shown in figure 3, this two muscle need later stage manual polishing to handle, takes very much.
Those skilled in the art knows, in actual production, the stainless steel cable of compacting is drawn than the stainless steel of hot-cast
Suo Chengben is low, and performance and appearance are the same.If can develop a kind of major diameter press type stainless steel cable and its
Production method will reduce the production cost of enterprise, improve the benefit of enterprise.
Invention content
The technical problem to be solved by the present invention is to:The major diameter stainless steel of a kind of press type, a diameter of 36~80mm are provided
Drag-line and preparation method thereof, the pressure pipe joint of the press type major diameter stainless steel cable crimp securely with stainless steel steel strand wires,
The product parameters such as minimum breaking force meet relevant regulations, and shape is very round, more attractive.
Solving the technical solution of above-mentioned technical problem is:A kind of major diameter stainless steel cable, including stainless steel steel strand wires and
