Circular pipe automatic cutting machine

Abstract

The invention discloses a circular pipe automatic cutting machine which comprises a rack, a workpiece bearing mechanism arranged on the rack, a host transmission system arranged at one end of the workpiece bearing mechanism, an automatic pipe inlet system arranged at the other end of the workpiece bearing mechanism and a knife holder control device arranged on the workpiece bearing mechanism; oneend of the workpiece bearing mechanism is further provided with an electric cabinet; the electric cabinet is arranged below the host transmission system; and the host transmission system can drive theworkpiece bearing mechanism to rotate. The circular pipe automatic cutting machine is reasonable in structure layout, simple in mounting and operation and convenient and practical in processing, realizes cutting automatic pipe inlet, weakens the operation intensity, reduces the cutting period time, improves the efficiency, reduces material waste and ensures the quality of a part due to accurate size of the cut part and thus achieves the purpose of efficient, accurate and safe cutting processing.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to an automatic circular pipe cutting machine. Background technique [0002] At present, when cutting steel pipes in the society, the feeding, cutting and other processes are completely manually operated. If a large batch of cutting is required, it needs to be moved and positioned multiple times. The operation is cumbersome, the work efficiency is low, and the labor intensity is high. [0003] There are three main types of equipment for cutting steel pipes. One is the sawing machine cutting method. The parallelism error of the end face of the steel pipe cut by this method is large and the processing accuracy is low; the second method is the turning method. The steel pipe rotates with the spindle at high speed, and the cutting knife The steel pipe is cut by feeding in a straight line perpendicular to the axis of the steel pipe.

Problems solved by technology

[0002] At present, when cutting steel pipes in the society, the feeding, cutting and other processes are completely manually operated. If a large batch of cutting is required, it needs to be moved and positioned multiple times. The operation is troublesome, the work efficiency is low, and the labor intensity is high.

[0003] There are three main types of equipment for cutting steel pipes. One is the sawing machine cutting method. The parallelism error of the end face of the steel pipe cut by this method is large and the processing accuracy is low; the second method is the turning method. The steel pipe rotates with the spindle at high speed, and the cutting knife The steel pipe is cut by feeding in a straight line perpendicular to the axis of the steel pipe. Since the iron filings are not easy to break, this cutting method is not suitable for cutting large-diameter steel pipes. The third method is the milling method. The steel pipe is fixed and the tool rotates at high speed. And cut the steel pipe by feeding in a straight line perpendicular to the axis of the steel pipe. Due to the limitation of the diameter of the tool, this cutting method is not suitable for cutting large-diameter steel pipes; the cutting force of turning and milling is relatively large. The strength of the tool, the cutting edge of the tool is relatively wide, the incision formed on the steel pipe is also wide, and the material to be cut is wasted.

The above three cutting methods can only cut one workpiece blank in one feed, and the processing efficiency is also low
