Description

Numerical control cutting machine for composite air pipe

Technical Field

The utility model relates to the technical field of cutting machines, in particular to a numerical control cutting machine for a composite air pipe.

Background

The electromechanical integrated cutting machine is called a numerical control cutting machine, such as a numerical control plasma cutting machine and a flame cutting machine, and drives a machine tool to move through a numerical program, and the cutting tool randomly carried along with the machine tool moves to cut an object. In the machining process, the common mode of plate cutting is manual cutting, semi-automatic cutting machine cutting and numerical control cutting machine cutting. The manual cutting is flexible and convenient, but the manual cutting has poor quality, large size error, large material waste and large subsequent processing workload, and meanwhile, the labor condition is bad and the production efficiency is low. The profile modeling cutting machine in the semi-automatic cutting machine is good in quality of cutting workpieces, and is not suitable for cutting single workpieces, small batches and large workpieces due to the fact that the profile modeling cutting machine uses a cutting die. Other types of semi-automatic cutting machines, while reducing the labor intensity of workers, are simple in function and are only suitable for cutting parts of more regular shapes. Compared with manual and semi-automatic cutting modes, the numerical control cutting can effectively improve the efficiency and the cutting quality of the plate cutting and lighten the labor intensity of operators. The composite air duct is made of rubber-plastic composite heat-insulating material, and can be used for completely replacing traditional air duct, air valve, air inlet, static pressure box and heat-insulating material in air-conditioner air-out system. The air pipe is installed after being cut by a cutting machine during assembly.

However, in the existing composite air duct cutting machine, as in the chinese patent publication No. CN212496442U, the position of the air duct is not fixed during the air duct cutting process, and the position is easily shifted during the air duct cutting, so that the air duct cutting size is inconsistent, the air duct needs to be cut again, the uneven cutting results in uneven cutting edge, and the uneven cutting edge is unfavorable for subsequent connection and installation, and the uneven cutting edge is also very easy to scratch the installer during the subsequent installation process, therefore, we propose a composite air duct numerical control cutting machine.
