【正文】 著木材工業(yè)的迅猛發(fā)展，砂光機已成為木材加工和家具行業(yè)廣泛應用的設備，砂光機的功能是：一、進行精確的幾何尺寸加工。 第一章 緒論 3 隨著中國改革開放帶來的信息技術(shù)，中國的木工機械廠家也開始研制自己的砂光機。 （ 4） 向高自動化程度發(fā)展。許多砂光機上采用了電子控制砂帶的橫向擺動，氣墊式壓帶器，電子控制分段式壓帶器，采用大直徑的硬度接觸輥，附設精光輥等措施。 砂光 機的發(fā)展趨勢 （ 1） 向高精度發(fā)展。 （ 4） 輔助時間少。尤其帶式砂光機，磨粒散熱時間間隔長。 砂光機的主要特點有： （ 1） 具有“快削法”之稱。目前，國外的砂光機越來越多的代替刨床加工。 致 謝 ................................................................................................... 錯誤 !未定義書簽。 Sander。 綜合以上考慮之后， 將本次設計內(nèi)容定為單面雙砂架上砂式寬帶砂光機的設計，輸送 帶送 料，輥式砂架粗 磨，壓磨式砂架精磨的組合。木工 砂帶機 也 就是 人稱之為 ： 帶式木工 砂光機 。砂帶機分為金屬類砂帶機和木工類砂帶機。 砂光機的特點是適應性強，能提高工作的尺寸精度，也能降低工件的表面 粗糙度，是木材加工的重要機床之一。 關(guān)鍵詞：寬帶；砂光機；壓磨式砂架；壓磨器；輥式砂架 The design of the sand fabrics 2 Lixiaojian (Machinery and transportation institute,Southwest forestry university, Kunming,Yunnan 650224 China) Digest:Belt Sander is one kind of the machine for reducing the surface roughness of the workpiece. belt sander Divided into metal kind of belt sander and carpentry belt sander .Carpentry sand is also what machine people called: belt woodworking sanding Sander is the equipment utilizing attrition tool for machining to every kind of board and woodwork ponent. The belt sander is widely applicated in the woodbased plate and furniture trade, the requirement is very large. The belt sander have lots of variety and develop fast in recent years. The sander have the characteristic of good adaptability, so it can improve the size precision of the work, take from the surface roughness of the work piece, being one of the important lathes of wood working. More prehensive consideration,so the design content as single double sand on sand in broadband sanding machine design .It has two sand belt shelves which locate on the up part of the sander, feed with track, and have the two kinds of sand shelves. To avoid too big vibrating from the gravity if it was located high, and the electrical engineer drives the roller with leather belt. And the bottom of the anchor bolt holes open have, before the use should be installed on fixed on the floor. This design attaches a good stability.
