Abstract: With the progress and development of society, aluminum profiles are more and more widely used in various fields of social life. The section of the profile is developed in the aspects of abnormity and large size, and the requirements for dimensional accuracy and the appearance of subsequent deep processing are also higher and higher. In this paper, the sawing of high-precision industrial aluminum profiles is discussed by Zhonglian Aluminum.
The concept of automobile lightweight, energy saving, and emission reduction is leading fashion and consumption. Green, energy-saving, and environmental protection products are attracting the attention of investors all over the world. Solar energy, wind energy, and other industries are becoming hot spots, and are getting rapid growth. The aluminum profile has the advantages of being lightweight, having good heat dissipation, good weather resistance, and high-cost performance. Therefore, the social demand for industrial aluminum profiles is changing greatly, and it is facing the best development opportunity.
Extruded aluminum profiles are mostly semi-finished products, to get a variety of practical products, deep processing is necessary. The industrial production of aluminum profiles is not a problem, but the deep processing and industrial production of aluminum profiles has become a pain in the heart of various enterprises. How to complete large quantities of orders with high precision requirements in a short time? It has become the biggest problem that enterprises need to face and improve production efficiency urgently. Product quality, production efficiency, and processing cost are in fierce competition among enterprises in this industry every day. And who can be the best in this industry? Undoubtedly, it is the enterprises with the strength of "quality first, cost lowest" in this industry that may become the final winner.
In mass production to achieve high efficiency, and low cost, sawing is undoubtedly a better choice.
Sawing processing of Aluminum profile
When it comes to cutting aluminum profiles, the first impression is to cut aluminum profiles into a certain length, that is, we often say the size cut. In fact, the aluminum sawing process can be simply divided into unidirectional sawing and universal sawing. Today, we are going to talk about the unidirectional sawing of aluminum profiles.
It is easier to understand unidirectional sawing, that is, the document piece and aluminum section parallel or at a certain Angle sawing. Although the principle of the unidirectional sawing process is relatively simple, to large quantities, high precision, high efficiency, and low-cost production and processing, are not so easy. Common problems are: cutting surface is not smooth, the burr is too large; the Aluminum profile surface is easy to scratch; Length and size are off. The following is an analysis of several common problems in the production process.
Sawing equipment.
Cut the spindle with a saw. Spindle radial and axial runout effect on cut surface quality, cut the size large (For example, spindle runout will lead to the cutting surface being serrated, the burr is too large), the spindle should be spherical roller bearings, roller, it has two columns in the mainly bear radial load at the same time can carry axial load in either direction, the heart performance is good, can compensate the alignment error, It greatly reduces the radial and axial runout of the saw blade and makes the cutting surface smooth.
Positioning improvement. The positioning adopts the combination of rigid positioning and a photoelectric induction device to avoid the bad cutting size caused by incomplete feeding, and the length error is reduced from ±0.5mm to ±0.1mm.
The other. Hard chrome plating on the contact surface of the feeding roller, workbench surface, and other products, and the installation of a vacuum cleaner and high-pressure air gun device to timely clean the saw-cut aluminum chips, prevent scratches on the surface to effectively protect the appearance of the workpiece, but also provide a clean working environment. In order to improve production efficiency and reduce costs, sawing is mostly a plurality of aluminum sawing at the same time, part of the surface treatment of aluminum profiles in the process of feeding, friction between the workpiece will lead to surface scratches. In view of this phenomenon, the feeding table can be added to the rotary, but also the lateral free sliding adjustment of the material column, so that the workpiece is effectively isolated, and will not cause surface scratches due to sliding friction between the workpiece.
