Abstract

The invention relates to an intelligent wire feeding machine. The machine comprises a frame, a wire welding disc, a wire feeding device and a control mechanism. The machine is characterized in that: the tail part of the frame is provided with a wire welding disc shaft; the wire feeding device fixed by bolts is arranged on a bottom plate below the frame; the side surface of the frame is provided with a supporting plate for fixation; the wire feeding device comprises a servo motor, a harmonic reducer, a panel, a wire feeding wheel, regulating wheels, a thumb wheel, a compression rod, a wheel bracket panel, a connecting rod, bearings, an encoder, a compression spring, a spring core shaft, a shaft sleeve, a sliding body, and a sliding body cover; the control mechanism is that: an embedded computer system is arranged in the intelligent wire feeding machine. According to the present invention, the servo control technology and the harmonic reducer are adopted, such that the operating stability of the welding wire at the low speed is effective controlled; the elastic floating device and the encoder are added, such that the control system is improved, the terminal close loop of the welding wire output movement is achieved, the wire feeding speed is real-timely monitored, and the damage probability of the laser processing workpiece due to the machine problem is reduced to the minimum.

Description

technical field [0001] The present invention relates to a wire feeder, in particular to a wire feeder which adopts servo control technology and a harmonic reducer to make the low-speed operation stable and reliable, to realize the closed loop at the end of the wire feed operation, and to have the function of communication and control with the upper computer, which is applied in laser processing in the wire feeder. Background technique [0002] In laser cladding processing, powder feeding processing and wire feeding processing can be used. The utilization rate of alloy powder in powder feeding processing does not exceed 50%. Due to the high price of alloy powder, the cost of laser cladding is relatively high. Laser manufacturing and remanufacturing are increasingly becoming an important means of low-carbon and circular economy. Effectively solving the cost problem of laser cladding can greatly reduce the cost of laser manufacturing and remanufacturing and expand the scope of ...

AI Technical Summary

Problems solved by technology

[0003] The wire feeders currently on the market are not suitable for laser cladding, and the following problems generally exist: First, the operation is unstable at low speed. During laser cladding, the welding wire is required to enter the molten pool at a low speed and stably. Once the speed fluctuates, It will cause spots on the surface of the laser processing, causing damage to the surface of the workpiece; second, the ordinary wire feeder does not have a wire feeding length or speed feedback system, and the wire feeding does not achieve a closed loop at the end, and the system cannot know that the welding wire is slipping or stuck. Cannot be applied to scale and mass production
