Embodiment 1

[0065] This embodiment provides a welding process for binding rods using drawn-arc stud welding, using a drawn-arc welding machine, including the following steps:

[0066] S11. Preparation before welding: Clean up the 25mm area around the welding place, do the workpiece test piece and destructive hammer test on the welding test plate, and then proceed to the next step after the workpiece test piece is qualified and there are no defects around it, and then mark the date on the workpiece test piece and save it 15 working days;

[0067] S1. Start the drawn arc welding machine, specifically connect the air source of the equipment, the air pressure is 0.6~0.8MPA, turn on the power of the equipment, adjust the welding parameters of the equipment according to the type and material of the binding rod, specifically, use Ф5 stainless steel binding wire Rod, the height of the stud is 50mm, the welding current is 720A, the welding time is 20ms, and the shielding gas is turned on. The shie...

Embodiment 2～8

[0091] Embodiments 2 to 8 are basically the same as Embodiments, except that the types of tie rods are different, and the corresponding welding parameters are different, which will not be repeated here, as shown in Table 1 for details:

[0092] Table 1

[0093] Example Cable tie model Tie rod material Welding current (A) Welding time (ms) 2 Ф5 SUS 740 25 3 Ф6 SUS 820 25 4 Ф6 SUS 840 30 5 Ф8 SUS 890 50 6 Ф8 SUS 910 60 7 Ф10 SUS 990 60 8 Ф10 SUS 1010 100

Embodiment 9

[0095] Such as Figures 11-15 As shown, the present embodiment provides a system for welding tie rods using drawn arc stud welding, including equipment power supply, equipment gas source, drawn arc welding machine 1, shielding gas delivery device 2, tie rod 3, welding Work piece 4, hammer test device 5, blanking and cutting device 6 and laser marking and positioning device 7,

[0096] The power supply of the device is connected to a drawn arc welding machine, and the drawn arc welding machine includes a welding torch 11, on which the wire rod 3 is installed through a clamp 12, and the clamp 12 includes an upper splint 121, a lower splint 122 and an adjustment handle 123, the upper splint 121 is hinged with the lower splint 122, and cooperates with the adjustment handle 123 to control the opening and closing of the clamp. Specifically, the two crank bolts 124 can be operated independently to gradually clamp the tie rod. The size of the tie rod 3 is Ф5, Ф6, Ф8 and Ф10, the mate...

Abstract

The invention relates to the technical field of welding, and discloses application of an arc discharging type stud welding technology to a welding tie pole. The defects of the traditional welding technology are overcome, arc discharging type stud welding is creatively introduced to the welding tie pole, and application of the arc discharging type stud welding to the tie pole is provided. The arc discharging type stud welding technology and device are scientifically improved, the arc discharging type stud welding technology is successfully applied to the tie pole, the obvious beneficial effects that the welding deformation is small, the number of adjustment working procedures is greatly reduced, even, adjustment is not needed, no welding splashes exist on the surface, the number of slag removing working procedures is reduced, and the welding defects caused by the manual factors are avoided are achieved, the improvement of product quality is ensured, the breaking phenomenon of the tie pole by a customer is obviously reduced, no wire filling is needed in the welding process, the production efficiency is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of welding technology, and more specifically, relates to the application of a drawn arc stud welding process in welding tie rods. Background technique [0002] The internal structure of the traction converter cabinet involves the wiring of electrical equipment. Proper wiring (such as wire selection and laying) can effectively reduce the interference of the external environment on the signal and the mutual interference between various cables, and improve the reliability of the on-board equipment. Sex, urban rail stainless steel cabinets often purchase welded stainless round steel (usually ф 6 or ф 8) cable rods are used for wiring when wiring, cable routing needs to be fixed, generally fixed with cable ties, and cable ties are Tie the cables to the tie rod. The tie bar is usually designed with metal materials such as stainless steel round steel or cold drawn round steel to ensure that the cables have sufficient electr...
