摘   要
现在工业上对中小型铸锻件进行表面清理和处理时，多采用抛丸处理工艺。其原理是将工件放在封闭

的容器中，用抛丸器对弹丸进行加速，加速后的弹丸直接撞击工件，将工件表面残余的铸砂或氧化皮

通过撞击而清理掉，从而达到清理工件表面的目的。同时在抛丸清理过程中，还可以使工件表面应力

状态得以改善，使其处于压应力状态，从而提高其疲劳强度。因此，铸、锻件的表面抛丸处理工艺在

工业上得到广泛的应用。
但现行工业上用的抛丸机存在如下两个方面的缺陷：
    1、抛丸器叶片多为直板形状，抛丸时磨损大寿命短，且机械效率低。
    2、工件在抛丸室内的位置相对于抛出弹丸的方向不能全方位调整，因此抛出的弹丸只能是撞击

到工件的部分表面，撞击不到的部分就得不到处理和清理，清理不完全。
   本论文的选题正是为了克服目前使用的抛丸机的上述缺点而选定的，围绕着上述两个缺点的克服

开展了研究。设计开发了“行星轮系多吊钩挂式抛丸机”和“管式、管式曲线叶片抛丸器”，从根本

上解决了现行抛丸清理机存在的两个主要缺点，该种形式的抛丸机已在青岛铸友铸造设备厂正式投入

生产，并在“山东潍坊冠宇机械制造有限公司”、“阳之光机械制造有限公司”和“山东森宇重工机

械有限公司”投入使用，使用效果得到明显改善。
    本论文的创新点主要有两点：
    1、用行星轮系吊钩代替了原来的盘式吊钩，在抛丸过程中，工件既有自转又有公转，工件表面

得到全方位的处理。
    2、抛丸器采用了“直管式、管式曲线形叶片”，提高了抛丸效率，减少了叶片的磨损量，延长

了叶片的使用寿命，降低了抛丸处理的成本。

Abstract
The shot blasting process are be used to surfase process and clean that middle or small

forge pieces in modern industry.The principle is to put the workepieces into sealed

container ,accellerate the bullet with shot blasting,and then the bullet impact against

worke pieces directly,so the sand and oxidize skin at surfase of pieces are be cleaned.

At the same time, it can improve surface stress condition, make it in press stress

condition, increase its fatigued strength.Therefor, this process is widly usedin

industry.
But there are tow defects at the shot blasting  which apllied in industry:
1.Most of the vane of shot blasting are straight form,and also it has large wear ,short

life time, low mechanical efficient.
2.The direction between the position of work pieces in container and blasting can not

adjusted in all direction.So the bullet only impact some surface of work pieces, and the

others will not process.
The selection of thesis subject is concerned to overcome above disadvantages of the shot

blasting in application.and research how to overcome them.In this paper ,We designed

suspend shot blasting which use planet gear box and the tubular curve vane shot

blasting. This construct of shot blasting resolve the above two diadvantages of shot

blasting recently used.
The new shot blasting has been producted in Qingdao Zhuyou Foundly Equipment Factory and

applied in Shandong Weifang Guanyu Machinery Manufacture Co Ltd.and Sunshine Machinery

Manufacture Co Ltd.and Shandong Senyu Heavy Machinery Co Ltd.The good effect have been

improved obviously.
There are tow innovates in this paper:
    1.Substitute the disc hook with planet gear box.It can make work piece but revolute

on its own axis also revolution on Public axis.So the work piece can be process in all

directions.
    2. The application of the tubular curve vane can increase blasting efeciebcy,

decrease wear of vane, increase life time of vane, decrease the cost of shot blasting

process.

Key words: shot blasting; planet gear box; tubular vane; air select;  dust eliminate
