CNC (completely numerical control) curve profile modeling saw cutting band sawing machine and use method thereof

Abstract

The invention relates to a CNC (completely numerical control) curve profile modeling saw cutting band sawing machine and a use method thereof. The CNC curve profile modeling saw cutting band sawing machine comprises a saw frame, a saw blade tensioning device, a workpiece horizontal pushing servo device, a workpiece clamping pushing pneumatic device, a saw-front workpiece pneumatic clamping device, a main transmission system, a support frame, a CNC system, a pneumatic system, a driving belt wheel, a driven belt wheel and a band saw blade, wherein the support frame is arranged at the side part of the saw frame, the CNC system controls the whole saw cutting band sawing machine equipment, a saw band guide device is also arranged on the saw frame, the saw band guide device comprises a saw band upper guide servo rotating device and a saw band lower guide servo rotating device, the saw band upper guide servo rotating device is positioned in the side near the driven belt wheel, the saw blade lower guide servo rotating device is positioned at the side near the driving belt wheel, and the saw band upper guide servo rotating device and the saw blade lower guide servo rotating device can synchronously and correspondingly rotate the band saw blade. The CNC curve profile modeling saw cutting band sawing machine and the use method have the advantages that the curve or special-shaped saw cutting can be realized, in addition, the mass production is realized, the workpiece precision consistency is good, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of band sawing machine equipment, and in particular relates to a full numerical control CNC curve profiling sawing band sawing machine and a use method thereof. Background technique [0002] With the development of industry, the improvement of people's living standards, and the improvement of aesthetic concepts, the demand for various beautiful materials is increasing. It is streamlined to increase the running speed. Therefore, the pantograph of the high-speed train is smoothly connected by multiple arcs with different curves according to the shape of the car body; furniture with various curves in our daily life, glass handicrafts, and stone handicrafts Etc. is also composed of curves. The existence of these curves brings beauty to our life and beautifies our life. However, some of these curves are formed in the form of casting, formed as blanks, and then finished by other machine tools. There are defects...

AI Technical Summary

Problems solved by technology

Due to the small diameter and insufficient strength of metal wires and diamond sand wires, they cannot be used for strong and efficient sawing. At the same time, the sand grains of diamond sand wires are produced by electroplating process, which are easy to fall off during the sawing process, with short service life and high cost.

For arc forming technologies such as waterjet and laser cutting, due to the inconsistency of material properties, some workpieces cannot be processed. Even if it can be completed, the cost of equipment investment and later use and maintenance is high, which is unacceptable for the furniture and handicraft industry.
