Embodiment 1

[0022] Such as figure 1 , the butt mold of the present embodiment Φ1.2mm magnesium welding wire includes 4 sets, including 4 sets, the structure of 4 sets of molds is the same, each set is divided into an upper mold and a lower mold, the upper mold includes a mold body 1, and the upper mold and the lower mold A vertical semicircular groove 2 is set on one side of the mold body 1 that is fastened by the mold, and four evenly distributed through holes 5 are arranged around the groove 2, and a heating wire 3 is installed on the through hole 5, and the heating wire 3 is connected to the power supply, and the middle of the mold body 1 The thermocouple 4 is arranged horizontally, and the thermocouple 4 is connected to the temperature controller; the structure of the lower mold is the same as that of the upper mold.

[0023] The mold is ordinary steel plate.

[0024] The thickness of the mold is not less than 30mm, the length is 50mm, and the width is 60mm.

[0025] The grooves 2 h...

Embodiment 2

[0030] The mold that this embodiment uses is identical with embodiment 1. The difference is that the thickness of the mold is not less than 30mm, the length is 20mm, and the width is 40mm.

[0031] Butt joint process of Φ1.2mm magnesium welding wire:

[0032] First, install the 2.0mm mold on the punching machine, connect the power supply, heat the mold, and adjust the temperature controller to 430°C. When the temperature rises to 430°C, start the butt joint of Φ1.2mm magnesium welding wire, and place the joint to be butted on the groove of the mold , the two joints are overlapped by 10mm, and the stamping is repeated 10 times; the molds of Φ1.6mm, Φ1.4mm, and Φ1.2mm are installed in sequence, and the operation process of the Φ2.0mm mold is repeated. , each 10 times. Use sandpaper to grind the joints of the joints to make the joints smooth and weld the wires to complete the butt joint.

Embodiment 3

[0034] The mold that this embodiment uses is identical with embodiment 1. The difference is that the thickness of the mold is not less than 30mm, the length is 40mm, and the width is 50mm.

[0035] Butt joint process of Φ1.2mm magnesium welding wire:

[0036] First, install the 2.0mm mold on the punching machine, connect the power supply, heat the mold, and adjust the temperature controller to 410°C. When the temperature rises to 410°C, start the butt joint of Φ1.2mm magnesium welding wire, and place the joint that needs to be butt in the mold groove 2 On the top, the two joints overlap by 20mm, and the stamping is repeated 12 times; the molds of Φ1.6mm, Φ1.4mm, and Φ1.2mm are installed in sequence, and the operation process of the Φ2.0mm mold is repeated. Stamping, 12 times each. Use sandpaper to grind the joints of the joints to make the joints smooth and weld the wires to complete the butt joint.

Abstract

The invention belongs to the field of welding, and particularly relates to a butt joint process and a butt joint die for a magnesium welding wire with 1.2 Phi. The process includes the first step of installing a die with 2.0mm Phi onto a punch, connecting a power source, heating the die, setting the temperature of the die to be 400-430 DEG C, starting butt joint of the magnesium welding wire with 1.2 Phi when the temperature of the die reaches a set value, putting joints needing butt joint on a die groove, enabling the two joints to be coincident, and carrying out punching repeatedly, and the second step of sequentially installing a die with 1.6mm Phi, a die with 1.4mm Phi and a die with 1.2mm Phi, repeating the operation process of the die with 2.0mm Phi, repeatedly punching the joints needing butt joint in the process, polishing joint marks of the joints and enabling the joints to be smooth. According to the butt joint process and the butt joint die for the magnesium welding wire with 1.2 Phi, butt joint on the magnesium welding wire with 1.2 Phi is achieved, the problem that wire breakage can happen easily in the process of winding is solved, the hard and brittle features are weakened, the welding method is simple and operation is easy.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a butt joint process of Φ1.2mm magnesium welding wire. Background technique [0002] When welding magnesium alloy products with smaller specifications, thinner magnesium alloy welding wire must be used. At present, Φ1.2mm magnesium welding wire is the welding wire with the smallest diameter on the market, and only a few enterprises have mastered its production, straightening, butt jointing and winding technologies. Magnesium welding wire is produced, straightened and wound into coils. However, in the actual winding process, each coil of welding wire needs to be continuous. Therefore, a suitable docking technique must be found. [0003] The thicker welding wire can be directly connected to the magnesium welding wire by welding and grinding. However, the Φ1.2mm magnesium welding wire has obvious hardness and brittleness after welding, and the wire is easily broken when windin...
