Above-mentioned situation is perplexing the stainless steel tube producer always.Because the steel pipe tangent plane has depression, the steel pipe aperture dwindles, and must earlier this concave face be equalized with pliers, maybe this is sentenced handsaw and amputates, and begins to carry out to combine with machining object or other construction, thereby prolongs man-hour, reduces steel pipe length, and processing cost is increased.Though also the someone attempts cutting with adenticulate saw blade, can produce the pitchy mark that forms owing to high temperature at the ora terminalis of cut surface.
The purpose of this utility model aims to provide a kind of improved stainless steel square tube cutter sweep, change with cut point, cooperate the displacement of buck in fixed point, the change of the saw blade number of teeth and rotating speed, thereby the fraction defective that will produce depression reduces to minimum, reach the raising quality of finished, reduce the purpose of manufacturing cost.
The utility model comprises body, substrate, buck, oil (gas) cylinder pressure, saw blade, holder, board and touch switch, establish slideway on the body, put on the slideway and can slide the substrate of making transverse shift thereon, buck is located at a side on the substrate, oil (gas) cylinder pressure is located at the opposite side of substrate, establish holder below saw blade, board is located at body rear end, and touch switch is located at origin or beginning, stage casing and the proximal end of board place and slideway respectively.Said substrate protrudes from the upper surface of body; Said holder is divided into two by the centre, is subjected to the control of two oil (gas) cylinder pressure respectively, and saw blade is arranged in the line of rabbet joint in the middle of two holders; Between holder and buck, establish a vertical grooved rail, at buck pedestal rear and establish and promote oil (gas) cylinder pressure that buck is made vertical shift.
The number of teeth of saw blade is 240～280 teeth, is preferably 280 teeth.The rotating speed of saw blade preferably changes 60/120 into by 30/60 common commentaries on classics simultaneously changes.
The utility model is by changing cut point, and the saw blade number of teeth and rotating speed cooperate the displacement of buck in fixed point, change cutting starting point, thus reduced the fraction defective that produces concave face, improved product quality, reduced manufacturing cost.
