Description

Composite material screw automatic welding machine

The invention relates to an automatic welding machine for composite screws, in particular to an automatic welding machine for welding head and tail workpieces of two different metal materials into composite screws.

Composite material screws combine two different metal materials to form a screw. Usually the metal materials of the head section and the tail section are different. The reason is that the tail section of the screw needs higher hardness to drill through harder materials. Plate, such as iron plate, and the head section is exposed outside the plate after being locked, so it must have anti-rust properties. Therefore, it is better to use stainless steel for the screw head section, so that the composite material screw is also rust-proof. and drilling and tapping intensity.

It is generally known that when welding composite material screws, the head workpiece and the tail workpiece are mainly used for manual single-point welding, or electric welding is used to weld a composite screw; however, manual spot welding is not economical and the processing speed is slow and the labor cost is too high. High, and most of the transmission methods of electric welding in transmitting the head workpieces and tail workpieces are in parallel arrangement for mobile transportation, and the head workpieces and tail workpieces are respectively transported to the electric welding bed for welding one by one. Due to the parallel arrangement and transmission When arriving at the electric welding bed, a mold base is required. The mold base is provided with a shaft. One end of the shaft is provided with a linking gear that can be toothed with the power source, so that the power source engages the linking gears at the same time to drive the The shaft rotates in the same direction, and the head workpiece and tail workpiece placed on the mold base are welded into a composite screw by the axis rotation. This structure is a process in which the head workpiece and the tail workpiece themselves are rotated by the axis and welded. It is too slow, and the mold base is easy to wear and its placement is not accurate enough, so that the head and tail sections cannot be welded tightly.

Therefore, the purpose of this new model is to provide an automatic welding machine for composite material screws, which can increase the processing speed, improve the welding quality, and reduce the processing cost.
