Problems solved by technology

However, due to the nature of the cutting, the sawing speed is relatively slow, which restricts the increase of the production line speed. On the other hand, due to the high price of the milling saw disc, the life of the saw disc is not high, which increases the production cost.
[0003] Finding new steel pipe sawing equipment to solve the problems of low production efficiency and high production cost of milling saws is an urgent problem to be solved in the development of welded pipe industry

Abstract

The invention discloses a differential rotary cutting saw for cutting off circular tubes, comprising a base, wherein a supporting jacket is fixedly connected on the base; a circular tube clamping device is arranged in the supporting jacket; a rotary sleeve is arranged on the excircle of the supporting jacket; a tool disc is fixed at one end of the rotary sleeve and is in slip connection with tool aprons; the tool aprons are connected with cutting-off tools and feed screws; the cutting-off tools are provided with radial feed drive mechanisms; and the tool disc is provided with a rotary drive mechanism. The saw is high in efficiency, low in cost and low in metal consumption and has the advantages of low noise, low power consumption, bright and clean saw bite, long tool life, low sawing cost and the like.

Description

Technical field [0001] The invention relates to a high-speed cutting technology, in particular to a differential rotary saw for cutting round pipes. Background technique [0002] At present, there are two types of flying saws that cut steel pipes online on the welded pipe production line, one is friction saw and the other is milling saw. Friction saws use high-speed rotating saw disks to cut steel pipes with full cross section. The friction flying saw sawing steel pipes has the disadvantages of high noise, high power consumption, short saw disk life, poor cutting quality, and high metal consumption; This sawing method for large-diameter, thick-walled and high-grade steel pipes has been difficult to adapt; the milling saw is a new type of steel pipe sawing equipment that has emerged in recent years. It uses two motion trajectory CNC milling saw disks to mill the steel pipe. The advantages of cutting are: due to the contour cutting, the cutting depth is small, the cutting resistan...
