Description

Feeding device for cutting metal pipe

Technical Field

The invention belongs to the technical field of metal pipe processing equipment, and particularly relates to a feeding device for cutting a metal pipe.

Background

The metal tube wide application is in various trades, like machinery, building etc, and the metal tube of production line output is generally longer, and in order to facilitate storage and transportation, need cut the metal tube into the metal tube of less length once more during the factory production, and the majority of pipe cutting machine in the market is manual material loading, single cutting, and workman intensity of labour is big, and cutting efficiency is low, and the cutter is because of frequent load life is short, has directly increased the manufacturing cost of enterprise.

At present, in a general pipe processing operation, in order to meet the requirement of pipe design, the pipe processing operation includes a trimming process step for a weld portion of the pipe, and a cutting step performed according to the length of the pipe design, and the cutting step can be combined with the trimming step of the weld portion and then performed. With the development of the modern machining industry, the requirements on the cutting quality and precision are continuously improved, the requirements on improving the cutting efficiency and reducing the cutting time are also improved, and in the process of machining metal pipes, most factories adopt water jet cutting. But the water jet cutting machine function is very single, does not possess conveyer on the water jet cutting machine, needs the staff to remove the area cutting tubular metal resonator and accomplishes the cutting under the water jet cutting machine during the cutting, and this process is wasted time and energy.

With the development of the modern machining industry, the requirements on the cutting quality and precision are continuously improved, and the requirements on improving the production efficiency, reducing the production cost and having a high-intelligent automatic cutting function are also improved. In the machining process, the common modes of plate cutting include manual cutting, semi-automatic cutting by a cutting machine and cutting by a numerical control cutting machine. The manual cutting is flexible and convenient, but the manual cutting quality is poor, the size error is large, the material waste is large, the subsequent processing workload is large, meanwhile, the labor condition is severe, and the production efficiency is low; the profile modeling cutting machine in the semi-automatic cutting machine has better quality of cutting workpieces, and is not suitable for cutting single workpieces, small batches and large workpieces due to the cutting die; although the other types of semi-automatic cutting machines reduce the labor intensity of workers, the semi-automatic cutting machines have simple functions and are only suitable for cutting parts with more regular shapes; compared with manual and semi-automatic cutting modes, the numerical control cutting method can effectively improve the efficiency and the cutting quality of the plate cutting and reduce the labor intensity of operators. Manual cutting and semi-automatic cutting are common in some small and medium-sized enterprises and even in some large-sized enterprises; at present, a plurality of problems exist in the cutting work of the metal pipe, such as manual cutting or semi-automatic cutting, poor working efficiency, poor quality and the like, which can not cut the metal pipe in batch. Meanwhile, most of the existing cutting machines aim at the condition of cutting a long section at one time, the metal pipe is usually required to be cut into small sections, if the original cutting machine is used for cutting only one section at one time, the labor is wasted, and the energy consumption is high.

The metal tube cutting machine is simple when the metal tube cutting machine is used for cutting metal tubes, metal scraps are remained on the cut metal tube section and the end opening of the metal tube to be cut after the metal tubes are cut in a whole row from left to right through the cutting cutter disc rotating at a high speed, and at the moment, the cutter disc is retracted from the right to the left for next cutting. The following disadvantages exist for such cutting: first, the end of the metal pipe is relatively neat after being cut, but when the metal pipe is cut back, the metal pipe is easily cut again, metal scraps are increased, and the neat cut is easily broken. Secondly, the quality of the steel pipe is easily affected by the high-temperature residual metal chips during cutting of the cut metal pipe section, and after the metal pipe section is sprayed by the cooling liquid, a large amount of metal chips are easily adhered to the metal pipe section and are difficult to remove because the cooling liquid is oily.

In the existing metal tube cutting device, the feeding device can only feed metal tubes with the same thickness at the same time, and only the metal tubes with the same length can be cut out when a plurality of metal tubes are cut at one time, so that the device is not suitable for diversified processing.
