33页1、摘 要胀管机,是用于扩大金属管端部的直径,以便扩大后的管子与管板连接部位紧密,使之不会漏水、漏气,并能承受一定的压力。适用于锅炉制造和安装及冷凝器、机车制造和维修。在传统的胀管工艺上,工业上采用胀管方法也是多种多样,而不同的胀管机械也会有诸多不同问题,从而使整个胀管行业参差不齐。本设计采用将等径圆柱体均分为多瓣称之为胀瓣,然后在胀瓣后端加工一个锥形槽,利用实心椎体材料在锥形槽轴向进给,两者配合,使胀瓣可以做有规则的径向扩张,从而带动需加工管件同步径向尺寸扩大的方法进行胀管。解决了市面上出现的胀管不均,胀接效率低和效果不好等问题,也使得所胀管材接口应力均匀,胀口稳定,另外在液压系统控制方面,采用了 PLC 自动控制系统,而且效率高,节省劳动力。此外,本设计胀管机与以前传统机械式胀管相比还具有工作平稳,成本低,噪音小等特点,也可以更换胀瓣,扩展机器可胀口管材直径范围,以满足不同客户对不同管径的需求。关键词:胀管机 液压系统 PLC ABSTRACTTube expander is used to expand the diameter of the metal tube end to th
2、e expanded tube to tube sheet joints tight, so it does not leak, and withstand certain pressure. For manufacture and installation of boilers, locomotive manufacturing and repair. In the traditional expanding technology, expander methods are varied, and different expander will have a lot of different issues, so that the entire expanded tube industry is mixed. This design uses the same diameter cylinders are divided into multiple petals - called the expansion valve, and then the back-end of expans
3、ion valve process a cone-shaped slot, with the tapered cylinder axial direction working, the expansion valve can be expanded with Radial direction, thus boosting the tube will be processed and simultaneously expand the size of radial expander. with this method, it can solve the problem of Expanding uneven Expansion inefficient and ineffective and so on in the market, it also makes the expansion pipe interface, uniform stress, swelling mouth stability, while in the hydraulic system control, also
