[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figure 1-Figure 3 The present invention provides a method for manufacturing a welding ring cable clamp, comprising:

[0036] Cutting the steel plate to obtain the ring cable groove plate 1;

[0037] Cutting the steel plate to obtain the radial cable plate 2;

[0038] A groove is formed along one end of the radial cable plate 2;

[0039] Butt one end of the radial cable plate 2 with the groove with the annular cable groove plate 1;

[0040] Argon-rich solid gas shielded welding is used to weld multiple layers of deposited welds 3 between the groove and the annular groove plate 1. After each layer of deposited weld 3 is welded, half the thickness of the deposited weld 3 is ground, and then the filling layer weld 4 is welded.

[0041] By machining a groove on the radial cable plate 2, adopting a groove design and using argon-rich solid gas shielded welding to weld multiple layers of deposited welds 3 to connect with the ring cable groove plate 1, and grinding half the thickness of the deposited weld 3 after each layer of weld is completed, the manufacturing and installation accuracy of the cable clamp can be guaranteed and welding deformation can be reduced. No stress relief annealing is required after welding, which reduces the difficulty of manufacturing the ring cable clamp, and gives full play to the advantages of low-alloy high-strength structural steel with high strength and uniform mechanical properties, thereby improving the performance of the ring cable clamp.

[0042] Furthermore, both the annular cable groove plate 1 and the radial cable plate 2 are cut by numerically controlled flame cutting.

[0043] Furthermore, the multi-layer weld 3 is preferably three layers, and the thickness of each layer does not exceed 6 mm. In this way, the cable clamp does not need heat treatment after welding, and the welding deformation of the cable clamp shape is less than ±1 mm.

[0044] A further optimization scheme, after cutting the steel plate to obtain the ring cable groove plate 1, also includes:

[0045] The area to be welded is polished on the ring groove plate 1 so that the area to be welded has a metallic luster, and ultrasonic testing and magnetic particle testing are used to test the internal and surface quality of the area to be welded, respectively, to ensure that there are no defects in the area to be welded that affect the welding quality.

[0046] A further optimized solution, after forming a groove along one end of the radial cable plate 2, further includes:

[0047] Polish the 25mm range on both sides of the groove to produce a metallic luster.

[0048] To further optimize the solution, the groove adopts a bilaterally symmetrical K-type groove, the groove angles on both sides are 45°, the root gap is 0 mm, and preferably, the thickness of the radial cable plate 2 is greater than 30 mm.

[0049] A further optimization scheme is to weld multiple layers of deposited welds 3 between the groove and the annular groove plate 1 by using argon-rich solid gas shielded welding, grind half the thickness of each layer of deposited weld 3 after welding, and then, in the process of welding the filling layer weld 4, further include:

[0050] The angle between the annular cable groove plate 1 and the radial cable plate 2 is controlled, preferably by means of a horse plate, reverse deformation, etc.

[0051] Further optimization scheme, when using argon-rich solid gas shielded welding, also includes:

[0052] The solid welding wire used is ER69-G with a diameter of Φ1.2mm and shielding gas (CO2+Ar).

[0053] Further optimization scheme, in the case of argon-rich solid gas shielded welding, also includes:

[0054] The welding current is 220-260A, the welding voltage is 24-30V, the welding speed is 30-40cm / min, the gas flow rate is 15-25L / min, and the welding position is horizontal.

[0055] Further optimization scheme, before adopting argon-rich solid gas shielded welding, also includes:

[0056] Control the preheating temperature of the annular cable groove plate 1 and the radial cable plate 2. When the thickness of the annular cable groove plate 1 and the radial cable plate 2 is ≤40mm, the preheating temperature is 120℃, and when the thickness is greater than 40-100mm, the preheating temperature is 130℃; the preheating temperature of the steel plate with a thickness greater than 100mm is 150℃.

[0057] A further optimized solution is to weld a multi-layer weld 3 between the groove and the ring cable groove plate 1, and then, when welding the filler layer weld, it also includes:

[0058] Control the interpass temperature of the previous deposited weld 3, and the interpass temperature is controlled at 150-200°.

[0059] By using appropriate welding materials and shielding gases, controlling the preheating temperature, and using reasonable welding process parameters, production efficiency is improved while ensuring welding mechanical properties.

[0060] A further optimization scheme, after cutting the steel plate to obtain the ring cable groove plate 1, also includes:

[0061] A plurality of cable grooves 5 are processed on the cable groove plate 1 to accommodate the cable ring 6 , and the cable ring 6 is bound in the cable groove 5 by a cover plate 7 and bolts 8 .

[0062] The cable groove 5 is machined in three stages by using the method of progressive machining of opposite variable cross-sections at both ends and arc side machining, which avoids the problem of tool bar vibration due to excessive machining stroke during machining, solves the influence of the cable clamp boss on the machining stroke, and reduces the machining difficulty.
