DW38数控弯管机机械设计.doc

摘要管的弯制方法有很多,相应的设备也有很多,但大多数都是用手动或机械弯管机加工生产出来的,而且多为冷弯。在实际中通常是根据生产对管的质量要求选择相应的弯管机进行加工。本课题旨在寻求一种新的弯管工艺,在保证弯管质量的前提下尽可能提高弯管的速度。本着以上的目的,本课题研究设计了一款 DW38 液压全自动弯管机。它具有生产效率较高,制造成本低。整台机器共有以下几部分组成:送料夹紧和送料机构、弯曲夹紧机构、弯曲机构和切断机构四大部分组成。除了切断机构是由一台功率为 的小功率三相异步电动机带动之外,其它的机构均采用了液压传动。弯管方式采用辗压。在弯管的过程中,定模保持不动,固定在旋转平台上的动模进行靠模完成管子的加工。由于主要采用了液压传动的传动方式,和其它的液压设备相同,该液压全自动弯管机在传动上大为简化,缩短了传动链,从而提高了动力的传动效率。本设备可以一次完成两根管料的同时加工,所以加工效率较高。关键词: 弯管机齿轮传动液压缸 1 ABSTRACT There are many bending method of tube, so the corresponding device isa lot. But most bending machine is manual or mechanical processing, and mostly is cold .In practice; the select of bending machine is usually based on the quality of the production requirements on tube. This topic seeks to find a new elbow technology, in ensuring the quality of pipe bends under the premise of improving the speed as much as possible. In the above purpose, the research design ofa hydraulic automatic tube bending machine. It has higher production efficiency, low manufacturing cost. The whole machine isa total of the ponents: Feeding clamping and feed mechanism, clamp body bending, bending bodies and cut off the bodies of four parts. In addition to cutting off body bya low-power power three phase induction motor drive, the other agencies are using a hydraulic transmission. Rolling Elbow is adopted. In the bending process, scheduled to die remain intact, fixed on the rotating platform, the dynamic model for the tube plete the processing by the module. Since the main use of the hydraulic drive transmission, and other similar hydraulic equipment, automatic bending machine of the hydraulic drive on the greatly simplified, reducing the transmission chain, resulting in improved power transmission efficiency. The device at once, while two pipe materials processing, so the processing efficiency is higher.
