Problems solved by technology

However, the structure of the wire feeding device at the front end of the welding equipment is complex, the motor heats up seriously, and the price is expensive, which increases the use cost of the enterprise. The wire feeding device at the front end of the welding torch is bulky, increases weight, limits the moving range of the welding torch, and reduces the flexibility and hand-held operation of the welding torch.

Embodiment 1

[0053] figure 1 It is a structural schematic diagram of the wire feeding device for gas metal arc welding of the present invention. Such as figure 1 As shown, the wire feeding device for gas metal arc welding includes a welding torch 1 and a wire feeding device 3 . The welding wire starts from the wire feeding mechanism 3 and reaches the welding torch 1 . The welding torch 1 includes a conductive tip, and the length of the welding wire between the conductive tip and the wire feeding mechanism 3 is not less than 50 cm.

[0054] When this embodiment is in use, the wire feeding mechanism 3 drives the welding wire to move, the wire feeding mechanism 3 can drive the welding wire forward or backward, and the wire feeding mechanism 3 can also drive the welding wire to accelerate or decelerate.

[0055]As a specific embodiment, the wire feeding mechanism 3 can drive the welding wire to advance or retreat periodically, and the wire feeding mechanism 3 can also drive the welding wire ...

Embodiment 2

[0067] The other structures in this embodiment are consistent with those in Embodiment 1. The main difference is that the two ends of the wire guide tube 2 in this embodiment do not need to be fixed, and the wire guide tube 2 is long enough to ensure that when the welding torch is working, no matter how it rotates Folding, the guide wire tube 2 is always under pressure in the length direction.

[0068] When this embodiment is in use, since the two ends of the guide wire tube 2 are always under pressure in the length direction, the same technical effect as that of the two ends in embodiment 1 is achieved. During specific use, the two ends of the wire guide tube 2 are respectively in contact with the wire feeding mechanism 3 and the welding gun 1, and the relative positions between the two ends of the wire guide tube 2 and the wire feeding mechanism 3 and the welding gun 1 are determined. The length of the welding wire is determined, that is, the length of the wire guide tube 2....

Embodiment 3

[0070] figure 2 It is an embodiment of the welding robot using the wire feeding device for gas metal arc welding in Embodiment 1. Such as figure 2 As shown, the welding machine robot also includes a wire feeding reel 5, a wire feeding tube 4 and a six-axis welding robot 6. The wire reel 5 provides welding wire, and the welding wire reaches the wire feeding mechanism 3 through the wire feeding tube 4, and the welding wire, driven by the wire feeding mechanism 3, reaches the welding torch 1 through the wire guiding tube 2 to participate in the welding process. The wire feeding mechanism 3 can drive the welding wire forward or backward. The wire feeding mechanism 3 and the welding torch are separated by the wire guide tube 2. The welding torch 1 includes a conductive tip installed at the front end of the welding torch 1. The length of welding wire should not be shorter than 50cm. The working part of the six-axis welding robot 6 holds the welding torch 1 .

Abstract

The invention discloses a consumable electrode gas shielded welding wire feeding device. The consumable electrode gas shielded welding wire feeding device comprises a welding gun and a wire feeding mechanism. The wire feeding mechanism can quickly change the wire feeding speed or direction, and the wire feeding change period of the wire feeding mechanism is matched with the molten drop transitionperiod. The welding gun comprises a conductive nozzle, and the length of a welding wire between the conductive nozzle and the wire feeding mechanism is not smaller than 50 cm. The wire feeding mechanism is arranged at the position a certain distance away from the conductive nozzle of the welding gun, the wire feeding speed or direction change is guaranteed so as to be matched with molten drop transition of gas shielded welding, meanwhile, separation of the welding gun and the wire feeding mechanism can be guaranteed to be achieved through low-cost manufacturing, good economy is achieved, meanwhile, the accessibility of the welding gun in a complex environment is improved, the weight of the welding gun is reduced, and use of the welding gun is facilitated. In addition, the wire feeding mechanism arranged in a separated mode has more sufficient conditions for heat dissipation, and the reliability and the load duration rate of the welding gun are further improved.

Description

technical field [0001] The invention relates to a gas shielded welding device, in particular to a gas metal shielded welding wire feeding device, a welding robot using the gas metal shielded welding wire feeding device, a manual gas metal shielded welding machine and a welding automation special machine. Background technique [0002] Gas-shielded welding is a welding method widely used in the industrial field. There are three main transition forms in gas-shielded welding, jet transition, droplet transition and short-circuit transition. The short-circuit transition welding method is widely used in the welding of low-carbon steel and low-alloy steel thin plates due to its many advantages. However, the welding process has a lot of spatter, which affects the appearance of the workpiece, deteriorates working conditions and causes environmental pollution. Many experts and scholars at home and abroad have carried out a lot of research work on welding materials, welding power suppl...
