Background
When producing prestressed steel strands, a fixed-length steel wire formed by continuous cold drawing of 82B large-size wire rods is adopted, a 1 x 7 structural steel strand is twisted on a strand machine set, and then the steel strand is rapidly cooled after a certain amount of elongation deformation is generated through stabilizing treatment, so that the characteristics of low relaxation, flatness and no looseness of the steel strand are realized. Each coil is about 16000m in length, the steel wire coil needs to be replaced after the previous coil is produced, welding needs to be carried out between the steel wires, the welding quality of the steel wires is improved, the production efficiency and the yield can be improved, and the safe operation risk is reduced.
When steel strands (mainly phi 7.9-15.7 mm) with different specifications are produced, corresponding steel wire diameters (mainly phi 2.7-5.42 mm) are obtained, a jaw groove of a steel wire welding machine is a V-shaped groove, different steel wire diameters cannot be considered, a large jaw of the welding machine cannot clamp a thin steel wire, a small jaw cannot clamp a thick steel wire, the current of an electric welding machine is large, the V-shaped groove is in contact with a steel wire line, and electric sparks are generated on the surface of the steel wire when the electric conductivity is large, so that the surface of the steel wire is burnt, and the welding quality and the welding efficiency of the; and the jaws are made of copper materials, so that the jaw is low in hardness, non-wear-resistant, fast in loss and high in cost.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model aims at providing a steel strand wires welding machine device of keeping silent increases the steel wire and keeps silent the groove contact surface, and arc groove edge adopts the straight line to press from both sides tightly simultaneously, guarantees that the steel wire presss from both sides tightly, electric conductive property is good, ensures steel wire welding quality and efficiency.
The utility model provides a technical scheme that above-mentioned problem adopted does: a jaw device of a steel strand welding machine comprises an upper jaw and a lower jaw; the upper jaw and the lower jaw are symmetrical in structure and clamp the steel wire after being combined; the middle parts of corresponding one sides of the upper jaw and the lower jaw are respectively provided with a groove, the section of each groove is in a similar semi-circle shape, the bottom surface is a semi-circular arc, and the two sides of each groove are respectively a planar left side wall and a planar right side wall.
A jaw device of a steel strand welding machine is characterized in that a heat-resistant coating is arranged on the surface of a semicircular arc bottom surface.
A jaw device of a steel strand welding machine is characterized in that wear-resistant coatings are arranged on the surfaces of a left side wall and a right side wall.
