Problems solved by technology

Among them, the front wire feeding device realizes the pulse wire feeding operation by using the servo speed regulating motor to change the speed of each wire feeding wheel in the wire feeding wheel group in real time, because the discontinuous acceleration and deceleration of each wire feeding wheel will bring discontinuous mechanical inertia As a result, the wire feed wheels are severely worn and their lifespan is severely shortened. At the same time, the micro-small DC motor servo speed regulation technology is not yet mature and popular, the cost is high, and the pulse wire feeding accuracy is low.

Embodiment 1

[0016] The working principle of the cold metal transition welding technology is to monitor the short-circuit transition process through the digital welding control system 20. When the digital welding control system 20 detects a short-circuit signal, it will feed back to the pulse wire feeding device, and the pulse wire feeding device quickly retracts the welding wire. In this way, the welding wire is separated from the droplet. At the same time, during the droplet separation and transition process, the digital welding control system 20 controls the current value loaded on the welding wire 4 to be almost zero, and the heat input is also almost zero at this time, which is greatly reduced. The welding heat input is reduced, so the cold metal transition welding technology is widely used in the welding field. In this embodiment, the pulsed wire feeding device is improved on the basis of the cold metal transfer welding technology, so that the cold metal transfer welding technology ca...

Embodiment 2

[0020] The difference between this embodiment and the first embodiment is that the wire feeding tube 1 described in this embodiment is a plastic hose, and the plastic hose will be in a state of natural bending with the welding process and its own gravity during use. The rest of the structures and usage methods are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0022] like figure 1 and figure 2 As shown, the difference between this embodiment and the first embodiment is that: a shoulder 61 made of magnetic material is provided at the front end of the guide tube 6, wherein the magnetic material can be metal materials such as iron. The rest of the structures and usage methods are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses low-spatter short-circuit gas shielded welding equipment. The low-spatter short-circuit gas shielded welding equipment comprises welding equipment with a digital welding control system, and a pulse wire feeding device, wherein the pulse wire feeding device comprises a rack and a wire feeding pipe, the front part of the wire feeding pipe is fixedly arranged in a welding nozzle of the welding equipment, a first wire feeding wheel and a second wire feeding wheel are movably arranged on the rack, a channel allowing a welding wire to pass through is formed in the mutually-engaged area of the first wire feeding wheel and the second wire feeding wheel, and the first wire feeding wheel and the second wire feeding wheel are driven by a drive device; and the tail part of thewire feeding pipe is movably arranged on a part located in front of the channel, of the rack, a slide device enabling the tail part of the wire feeding pipe to carry out horizontal reciprocating movement in the front-rear direction relative to the rack is arranged on the tail part of the wire feeding pipe, and a control circuit in the slide device is connected with the digital welding control system. According to the equipment, the welding effect is further improved on the basis of ensuring non-spatter cold transition of molten drops.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a low-splash short-circuit gas shielded welding equipment. Background technique [0002] Cold metal transition welding technology (referred to as CMT) is a new type of welding technology without welding slag spatter. The so-called cold metal transition refers to the monitoring of the short arc and the reversing wire feeding of the welding wire under the digital control mode. Among them, the reversing wire feeding system is composed of front and rear two sets of wire feeding devices that work together, so that the welding wire feeding process is intermittent. The rear wire feeding device feeds the wire forward at a constant wire feeding speed, and the front wire feeding device controls the pulsed welding wire delivery at a frequency of 70Hz in accordance with the instructions of the control system. Among them, the front wire feeding device realizes the pulse wire feeding operat...
