Synchronous cutting method during pipe discharging

Abstract

The invention relates to the technical field of pipe machining, in particular to a synchronous cutting method during pipe discharging. The synchronous cutting method comprises the following steps that S1, a pipe is conveyed into a cutting machine and extends into a cutting device, and the extending speed of the pipe is V1; S2, the length of the pipe needing to be cut off is L1, when the extending length of the pipe reaches L2, wherein L2 is smaller than L1, a control system controls the cutting device to start to move and accelerate, when the cutting device moves by a distance D, the speed V2 of the cutting device is equal to the extending speed V1 of the pipe, wherein L2=L1-D, and D is equal to the moving distance that the control system controls the cutting device (1) to start to move and accelerate to the speed V1; and S3, when V2 is equal to V1, the cutting device and the pipe are controlled to move at the same speed, and the control system controls a cutting head on the cutting device to rotate at the same time so as to cut and obtain a pipe with the length of L1. Discharging and cutting are conducted synchronously, consumption of manpower and material resources in the pipe discharging, transporting and feeding process is avoided, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a method for synchronously cutting pipes when they are discharged. Background technique [0002] In the existing pipe production process, the forming and cutting are separated separately, and different machines are used for processing; generally, the pipe is first processed by the pipe extrusion program device and then unloaded, and then transported to the cutting machine at the cutting station. The feeding device feeds the pipe material into the cutting machine for cutting, so as to be processed into pipes of required length. In this process, after the pipe is formed, it needs to be unloaded, transported, and loaded before it can be cut by the cutting machine, so it needs to consume more manpower and material resources, and the production efficiency is low.
