Pipe cutter

Abstract

The invention relates to a pipe cutter, which comprises: frame (60), work table (61), aerated or hydraulic device, connecting tube valve, cutting motor (1) axially mounted at one end of work table (61), and the cutter driven by said motor (1). Wherein, the work table (61) and frame (60) are mounted with a device for moving cutting motor (1) and cutter up and down, and a device for rotating the pipe (12) around its axle; the end of work table (61) far from the motor (1) has automatic pipe feeder; the work table (61) between cutter and pipe feeder is mounted with pipe guide support and pipe automatic clamper; one side of motor (1) has pipe (12) automatic sizing device under. The invention has high vertical degree between cutting surface and pipe axle, with high efficiency and low cost.

Description

technical field [0001] The invention relates to a mechanical processing equipment, in particular to a pipe cutting machine. Background technique [0002] The pipe cutting of the prior art generally adopts an emery wheel cutting machine to grind off, a bow sawing machine and a band sawing machine to saw off, a manual cutter ring cut and a common lathe to cut off, etc. Grinding wheel cutting machine grinding, bow sawing machine and band sawing machine sawing, and manual cutter ring cutting all have the following defects: 1. The loading and unloading adopts manual adjustment screw rod to compress and loosen the pipe fittings (ie pipe workpieces), and its speed is slow; 2. The length of the ruler is manually controlled, and the size is inaccurate; 3. During the processing of pipe fittings, the pipe fittings are still, and the verticality between the cutting end surface and the pipe axis is low; 4. The processing process, especially batch processing, uses manual clamping, looseni...

AI Technical Summary

Problems solved by technology

Grinding wheel cutting machine grinding, bow sawing machine and band sawing machine sawing, and manual cutter ring cutting all have the following defects: 1. The loading and unloading adopts manual adjustment screw rod to compress and loosen the pipe fittings (ie pipe workpieces), and its speed is slow; 2. The length of the ruler is manually controlled, and the size is inaccurate; 3. During the processing of pipe fittings, the pipe fittings are still, and the verticality between the cutting end surface and the pipe axis is low; 4. The processing process, especially batch processing, uses manual clamping, loosening, feeding, and positioning. ruler, etc., which is labor-intensive and low in production efficiency

Although ordinary lathes have overcome the third shortcoming above, they still have the following defects: high labor intensity, low production efficiency, and high processing costs

[0003] Although the Chinese patent application documents disclose some pipe cutting machines, some are limited to large-diameter pipelines for on-site construction and maintenance, others focus on PVS pipe chamfering, and others are limited to certain devices of the pipe cutting machine such as cutting Feed device improvement, etc.

So far, no pipe cutting machine has been found with full functions, high degree of automation and can be widely used in technical fields such as machinery manufacturing and batch processing of pipe products.
