A fully automatic CNC bending equipment for silver-free welding wire

Abstract

A full-automatic numerical control bending device of a silver-free welding wire comprises a machine frame and a feeding frame. A straightening part for flattening a welding wire coming from the feeding frame, a feeding part for pulling the welding wire for feeding or retreating, a cutting-off part for cutting off the welding wire and a bending part for bending the welding wire are sequentially arranged on the machine frame in the feeding direction of the welding wire. The straightening part, the feeding part, the cutting-off part and the bending part are provided with a first channel, a second channel, a third channel and a fourth channel for the welding wire to horizontally pass through respectively. The first channel, the second channel and the third channel are aligned and communicated, and the fourth channel can be horizontally communicated with the first channel, the second channel and the third channel so that the welding wire can sequentially pass through the straightening part, the feeding part and the cutting-off part to horizontally extend to the bending part from the feeding frame. The full-automatic numerical control bending device further comprises a controller which is connected with the feeding part, the cutting-off part and the bending part.

Description

technical field [0001] The invention belongs to the technical field of processing, and in particular relates to a fully automatic numerical control bending equipment for silver-free welding wire. Background technique [0002] The cooler is located under the furnace to cool the glass fiber drawn from the molten glass medium in the furnace. It is a device for cooling the glass fiber in wire drawing. Silver-free welding wire is an important welding material in the processing of the cooler. , with high strength characteristics. [0003] The cooler is made of copper. Under high temperature and chemical environment, the service life of copper is limited, and the replacement frequency is high; and the cooler consumes a lot, so the demand for silver-free welding wire for welding is large. [0004] At present, the silver-free welding wire used for welding the cooler needs to be bent into a U shape. When welding, the U-shaped welding wire is directly clamped on the periphery of the c...

AI Technical Summary

Problems solved by technology

[0006] This bending method has the disadvantages of high labor intensity, low efficiency, poor standardization of bending degree, and easy waste of raw materials. The details are as follows:

[0007] High labor intensity: large demand for coolers, large demand for welding wire, bending by manual lever alone, long working hours and high strength;

[0008] Low efficiency: relying on manual implementation, a U-shaped welding wire needs to be divided into two steps of cutting and bending;

[0009] Poor standardization of bending degree: manual bending welding wire has poor standardization of shearing and bending, and low degree of precise control. Although there are equipment and molds for shearing and bending, it is controlled by human operation, and the precise control of welding wire length and bending degree is poor.

It is prone to problems such as deviation of welding wire length, excessive U-shaped bending, insufficient or excessive bending of welding wire, and uneven or excessive application of welding wire during welding, so that the U-shaped angle needs to be corrected again, not only the effect of U-shaped silver-free welding wire time consuming
