Problems solved by technology

There are relevant standards that stipulate that the pressed stainless steel cable can only be 36 mm in size, and there is no stainless steel cable larger than 36 mm that can be pressed into shape in actual production.
[0003] In addition, existing pressed stainless steel cables (such as figure 1 shown) the conventional crimping method is to press up and down (such as figure 2 As shown), the appearance of the pressed cable anchor head is not round enough, and it is not tight enough. A 36mm steel strand needs a 3,000-ton press to press it firmly, and a larger steel strand cannot be crimped firmly.
And the crimping head is slightly flat, and there will be two ribs on the contact surface of the upper and lower dies on both sides, such as image 3 As shown, these two ribs need to be manually polished in the later stage, which is very time-consuming

Embodiment 1

[0038] Embodiment 1: a kind of large-diameter stainless steel cable, such as Figure 4-Figure 8 As shown, it includes a stainless steel strand 1 and two pressure pipe joints 2. The pressure pipe joint has an inner hole 21, and the inner hole 21 of the pressure pipe joint is composed of an inclined hole 211 and an equal diameter hole 212. , the diameter of the inclined hole gradually decreases from the end to the middle, the minimum diameter of the inclined hole is the same as the diameter of the equal diameter hole, and a taper plug 3 is respectively set on the central wire 11 at both ends of the stainless steel strand, The two ends of the stainless steel stranded wire respectively penetrate into the inner hole of the pressure pipe joint and form an integral body with the pressure pipe joint through pressing. The diameter of the stainless steel stranded wire is 36-80 mm.

[0039] In this embodiment, the taper plug 3 is a circular truncated structure with a central hole 31, the...

Embodiment 2

[0040] Embodiment 2: a kind of manufacture method of the large-diameter stainless steel cable as described in embodiment 1, comprises the following steps:

[0041] (1) Take a stainless steel strand 1 with a diameter of 36-80 mm, first insert the annular extrusion die 5 into the stainless steel strand, the middle part of the annular extrusion die is an extrusion forming hole 51, and the annular extrusion The length of the extruding hole 51 of mold is 75~85mm, preferably 80mm, and the extruding hole is made of tapered hole 511 and integral circular hole 512, and the length of tapered hole 511 and integral circular hole 512 is 40mm respectively Left and right, the tapered hole of the annular extrusion die faces the end of the stainless steel strand;

[0042] (2) Drive a taper plug 3 into the center wire 11 at one end of the stainless steel strand 2; the taper plug 3 is a circular truncated structure with a central hole 31, and the diameter of the large end of the taper plug is 1 / ...

Abstract

The invention relates to a large-diameter stainless steel stay cable and a manufacturing method thereof. The large-diameter stainless steel stay cable comprises a stainless steel stranded wire and twopressure pipe joints, wherein an inner hole is formed in the pressure pipe joints, and the inner hole of the pressure pipe joints is composed of an inclined hole and an equal-diameter hole; the diameter of the inclined hole is gradually reduced from the end part to the middle, and the minimum diameter of the inclined hole is the same as the diameter of the equal-diameter hole; center wires at thetwo ends of the stainless steel stranded wire are correspondingly sleeved with conical plugs, the two ends of the stainless steel stranded wire correspondingly penetrate into the inner hole of the pressure pipe joints and are formed into one body with the pressure pipe joints through compression, and the diameter of the stainless steel stranded wire is 36-80 mm. According to the large-diameter stainless steel stay cable, a novel production process is adopted so that the pressing type large-diameter stainless steel stay cable with the diameter of 36-80 mm can be machined, the product parameters such as the minimum breaking tensile force and the like meet relevant regulations, furthermore, the appearance is round, and the appearance is more attractive.

Description

technical field [0001] The invention relates to a stainless steel cable and a manufacturing method thereof, in particular to a large-diameter stainless steel cable and a manufacturing method thereof. Background technique [0002] At present, there are two types of stainless steel cables on the market, one is hot-cast stainless steel cables, and the other is pressed stainless steel cables; the cables with a diameter of less than 36 mm are pressed types, and the stainless steel cables with a diameter of more than 36 mm are pressed. The cable is hot cast. Relevant standards stipulate that the pressed stainless steel cable can only be 36 mm in size, and there is no stainless steel cable larger than 36 mm in actual production that can be formed by pressing. [0003] In addition, existing pressed stainless steel cables (such as figure 1 shown) the conventional crimping method is to press up and down (such as figure 2 As shown), the appearance of the pressed cable anchor head i...
