Description

The gang saw unit

Technical field

The utility model relates to the steel tubular goods sawing device, is specially adapted to arrange many a kind of gang saw units of using with cut-out, crop, the back-end crop of footpath steel pipe.

Background technology

At present, the equipment that sawing machine is at home and abroad produced is diversified, it is by the buhl saw body that base is arranged, the saw blade that motor, transmission case drive, hand feed, alignment size device, clamping device are formed, single steel pipe is sent into from saw body one end, after the alignment of alignment size device, steel pipe is clamped with manual or simple and mechanical, by the saw blade that motor, transmission case drive steel pipe is carried out the feeding cut-out with manual operating then, it has following weak point:

1, the saw body of existing sawing machine is an integral body, wants horizontal discharging behind steel pipe feeding sawing machine, must withdraw from and pass in and out sawing machine and could laterally go out the raising that pipe certainly will influence output so later on.

2, sawing ability is restricted, different for thickness of steel pipe and material often, and the raising of saw blade revolution is very difficult.If rotating speed is too fast, the saw blade that is bound to produces the shake pendulum and skew is shaken and then blade wear is serious.

3, because the saw blade main axis rotation is because the engaged transmission that the transmission case internal gear is paid, often owing to the reason of Gear Processing precision and assembling causes the excessive thereby saw blade of backlash when cutting with steel pipe, continual generation is impacted often to cause and is played tooth phenomenon and damage.

4, the tight steel pipe of clamp head-clamp, or else the tension that is not folder is exactly to become flexible, and is that to operate labour intensity manually big.

Summary of the invention

The utility model purpose is weak point and the defective that exists in above-mentioned technology, can sawing different-thickness tubing and provide, reliable clamping reduces saw blade and damages, can vertical, horizontal enhance productivity and compact conformation a kind of gang saw unit easy to use again into and out of tubing.
