Precise and fine wire feeding machine

Abstract

The invention provides a precise and fine wire feeding machine which comprises a machine frame groove, a wire feeding guide tube, a wire discharging guide tube and a pressing mechanism. The wire feeding guide tube is arranged on one side wall of the machine frame groove, the wire discharging guide tube is arranged on the other side wall of the machine frame groove, and the wire feeding guide tubeand the wire discharging guide tube are located in the same straight line to form a wire feeding route. The pressing mechanism is mounted in the machine frame groove and located on one side of the wire feeding route. The precise and fine wire feeding machine further comprises a transmission mechanism arranged on the other side of the wire feeding route. The transmission mechanism comprises a motor, a driving wheel and a driven wheel. The motor is fixedly mounted on the machine rack groove, and an output shaft of the motor is provided with the driving wheel. The driven wheel is fixedly mountedin the machine frame groove and is engaged with the driving wheel. The driving wheel and the pressing mechanism are matched to achieve wire feeding. The driving wheel is engaged with the driving wheelwith different tooth number, the different transmission ratio requirements can be met, and different wire feeding speed is obtained.

Description

technical field [0001] The invention relates to the field of wire feeding equipment, in particular to a precision fine wire feeding machine. Background technique [0002] At present, in the field of metal welding, connector welding in the electrical and electronic industry, non-contact welding inside small relays, non-contact welding of silver contacts of AC contactors, leakage protectors, and bulb filaments, high-voltage copper tubes in the refrigeration industry Welding, welding between various components in the jewelry industry and welding in the metal jewelry and metal crafts metal manufacturing industry all require high precision and high quality, so there is a higher requirement for the wire feeder in welding. However, the traditional welding mainly uses welding wire above Φ0.8mm, which makes the wire feeder larger in size and severely limits its scope of application. [0003] For this reason, many efforts have been made to improve the performance of wire feeders. Ch...

Problems solved by technology

[0004] With the above-mentioned structure, although the delivery requirements of wires with different diameters are met to a certain extent, this wire feeder drives two sets of extrusion wheels to transfer wires through a motor. The structure is complicated, and the speed of wire transfer is controlled by the motor itself. The speed is determined by the speed, so that the speed range of wire feeding is narrowed, so that its applicability is reduced, and this structure has problems such as inconvenient wire replacement and inconvenient adjustment of the pressing mechanism.
