文档介绍：高效锯片抛光机设计(抛光进给装置)
摘要
金刚石圆锯片广泛应用于石材行业,按规格分类,国内石材加工锯片基体规格从φ200mm起始,最大达φ3500mm(国外最大圆锯片的规格为φ5000mm)。其中,φ200~600mm规格主要用于半成品板材的剪裁(裁边)加工;φ650mm以上规格主要用于类似墓碑、墓柱等较厚石板(柱)的成型锯切加工,以及用于荒料的锯切成(板)材加工。目前尤以φ1600mm锯片基体使用最为普遍。
随着竞争的日益激烈,对中等直径锯片的加工要求越来越高,这就要求改进生产工艺,提高产品质量,增加产品的附加值,同时降低生产成本,提高生产效率。目前,市场上的抛光机均采用单面抛光,生产效率低;且多是卧式,占地面积大。本课题拟采用双锯片抛光方案,在功率不变的前提下,可同时抛光两个锯片,也可单独加工,从而生产效率可提高将近一倍;并将原来的卧式结构改进为立式结构,占地面积减小。
本锯片抛光机抛光进给装置拟采用砂带磨削技术。砂带磨削工艺是将环形砂带套在接触轮和张紧轮的外圆上,在张紧的状态下,使高速旋转的砂带表面与工件的加工表面相接触,并在一定的压力作用下,以产生的相对摩擦运动(切削运动)对工件表面进行磨削加工的一种工艺方法。

Design of The Highly Effective Saw Blade PG1800 Polishing Machine (Polishing Work Feeder)
Abstract
Diamond saw blades are widely used in stone industry. By size category, the specifications of domestic blade for stone processing are from 200 mm. And the largest is up to 3500 mm (the foreign largest saw blade specification is 5000 mm). Among them, the saw blades between 200 and 600 mm are mainly used in semi-finished trim plates (cut side) processing. The saw blades which larger than 650 mm are used in forming sawing of thick columns like tombstones and tomb column; furthermore they are used in the saw cutting processing of bland to sheet. Especially, the 1600 mm saw blades are the mon used in recent years.
With petition, the processing of medium diameter blade is highly demanded. It requires improved technology of production, high quality and increasing value to their products. At the same time reduce production costs and increase productivity. At present, in the market lays many one-sided polishing machines which have low efficiency of production. And are the horizontal-type which use large area. This topic plans to use the double saw blade. Without changing the power, it can polish two saw blades in the same time. And can also process separately. The production efficiency might enhance a time. We want to change the original horizontal-type to vertical structure. And reduce the area of machine.
The polishing work feeder of this
