A solder screening device

Abstract

The invention relates to a solder screening device, comprising a solder frame and a solder slag frame, the solder frame is located directly below the solder slag frame, a ring spring is fixed on the inner wall of the solder frame, and the inner ends of the springs are all fixed on the solder slag frame On the frame body, the bottom surface of the solder frame is a slope with low left and high right, the lower part of the left end face of the solder frame is provided with a chemical outlet, the bottom surface of the solder slag frame is a slope with high left and low right, and the bottom of the solder frame is a slope with high left and low right. The bottom surface is made of screen mesh, and the lower part of the right end surface of the welding slag frame is provided with a slag outlet, which is located above the chemical outlet and extends to the outside of the solder frame; the left end surface of the welding slag frame is equipped with a vibration motor. Under the vibration of the vibrating motor, the mixture of solder and welding slag is separated on the screen. Since the screen is tilted, the welding slag and solder can be separated quickly to prevent the welding slag from being shattered and mixed into the solder; the welding slag frame is placed entirely on the solder In the frame, under the connection effect of the support column, the connection firmness of the welding slag frame is ensured, and the degree of freedom of the welding slag frame is not affected.

Description

technical field [0001] The invention relates to the technical field of solder screening equipment, in particular to a solder screening device. Background technique [0002] In the process of submerged arc welding, the solder is continuously fed along with the welding wire, and falls to the surface of the part with the welding wire. Some solder is integrated with the molten metal welding liquid to form welding slag, and some solder falls directly without use to form waste. These scraps still have use value after re-screening, so this part of the solder needs to be processed. [0003] The existing screening method is carried out by vibrating motor, and the screen is in a flat state. Using this screen to screen solder and welding slag can easily cause the welding slag to break under excessive vibration and mix with the solder, affecting the purity of the solder. When it is used again, it is easy to form bubbles or welding spots on the surface of the parts during the submerged ...

[0003] The existing screening method is carried out by vibrating motor, and the screen is in a flat state. Using this screen to screen solder and welding slag can easily cause the welding slag to break under excessive vibration and mix with the solder, affecting the purity of the solder. When used again, it is easy to form bubbles or welding spots on the surface of the parts during submerged arc welding, which seriously affects the welding quality
