Problems solved by technology

The existing argon arc welding pulse wire feeding device realizes the pulse wire feeding operation by changing the speed of each wire feed wheel in the wire feed wheel group in real time by using a servo speed regulating motor, because the discontinuous acceleration and deceleration of each wire feed wheel will bring The discontinuous change of mechanical inertia causes serious wear and tear of each wire feed wheel and shortens its lifespan. At the same time, the micro DC motor servo speed regulation technology is not yet mature and popular, the cost is high, and the precision of pulse wire feeding is low.

Embodiment 1

[0015] The argon arc welding pulse wire feeding device needs to be used in conjunction with the welding equipment, and the two are connected through the wire feeding tube 1. In actual use, affected by the use requirements, the length of the wire feeding tube 1 can generally reach more than 0.5 meters. . Such as figure 1 and figure 2 As shown, the argon arc welding pulsed wire feeding device described in this embodiment includes a frame and a wire feeding tube 1, and the head of the wire feeding tube 1 is fixedly arranged in the welding tip 7 of the welding equipment. The first wire feed roll 2 and the second wire feed roll 3 are movably arranged on the frame, and the interlocking area of ​​the first wire feed roll 2 and the second wire feed roll 3 constitutes a passage for the welding wire 4 to pass through. Here, for the convenience of description, Define the direction in which welding wire 4 is output from the channel as front. The first wire feed roller 2 and the second...

Embodiment 2

[0018] 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

[0020] Such as 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 an argon arc welding pulse wire feeding device. The device comprises a machine frame and a wire feeding tube, a first wire feeding wheel and a second wire feeding wheel are movably arranged on the machine frame, the first wire feeding wheel and the second wire feeding wheel are meshed with each other, a meshed area of the first wire feeding wheel and the second wire feedingwheel forms a channel for welding wires to pass through, and the first wire feeding wheel and the second wire feeding wheel are driven by a driving device; in the driving of the driving device, the first wire feeding wheel and the second wire feeding wheel rotate at a constant speed and are meshed to push the welding wires located in the channel, so that the welding wires move forwards at a uniform speed; and the tail of the wire feeding tube is movably arranged on a machine frame located in front of the channel, a sliding device enabling the tail part of the wire feeding tube to horizontallymove back and forth relative to the machine frame arranged at the tail part of the wire feeding pipe. The pulse wire feeding precision of the argon arc welding pulse wire feeding device is high, theservice life is long, and the cost is low.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an efficient argon arc welding pulse wire feeding device. Background technique [0002] Welding equipment such as an argon arc welding machine is usually used in conjunction with an argon arc welding wire feeding device. During operation, the welding wire is fed into the welding tip of the argon arc welding machine through the wire feeding wheel set in the argon arc welding wire feeding device. At present, there are many kinds of argon arc welding wire feeding devices, among which the argon arc welding pulse wire feeding device is one of the more common argon arc welding wire feeding devices. The existing argon arc welding pulse wire feeding device realizes the pulse wire feeding operation by changing the speed of each wire feed wheel in the wire feed wheel group in real time by using a servo speed regulating motor, because the discontinuous acceleration and deceleration of each...
