Technical Field

The invention relates to the technical field of copper bar cutting equipment, in particular to a copper bar cutting machine for copper industry.

Background

The copper bar is one of non-ferrous metal processing bars, and has good processing performance and high conductivity. The brass rod is a rod-shaped object made of copper and zinc alloy and is named after yellow color. The melting point of the brass with the copper content of 56% -68% is 934-967 ℃. Brass has good mechanical property and wear resistance, and can be used for manufacturing precision instruments, ship parts, shell shells of guns and the like. The color can be different when the zinc content is different, for example, the color is red yellow when the zinc content is 18-20 percent, and brown yellow when the zinc content is 20-30 percent. In addition, brass is unique in sound when being knocked up, so that instruments such as gongs, cymbals, bells and horns in the east, brass instruments in the west and the like are all made of brass.

During bar copper reprocesses, need the bar copper to cut off, so that be applicable to the use of different positions, however current bar copper cutter has had a large amount of shortcomings, for example current bar copper cutter can not be fine cut the bar copper, current bar copper cutter is only simple presss from both sides tightly the bar copper, so that at the in-process of cutting, the bar copper takes place to remove, thereby the effect of cutting off has been reduced, and current bar copper cutter anchor clamps do not have apart from regulatory function, so that can not satisfy the cutting of different length bar copper, great reduction the usability of bar copper.
