在带料连续下料成等长条料的生产线中,怎样准确控制切下条料的长度误差,是个十分棘手的问题。以往为了满足公差要求,采用的定位机构和控制系统相当复杂。下面介绍一种简单有效的辊送料油缸慢速准确定位机构。天水锻压机床厂在铜铝复合太阳能吸热片加工生产线的设计制造过程中,用户提出了一项技术参数:加工出的吸热片成品长度为1800mm,其公差为±1.0mm。从表面看此属自由公差范围,故采用了如下方案,即用制动电机
It is a very tricky problem how to accurately control the length error of cut strips in the production line with continuous feeding of the strip material into an equal length of strip. In the past in order to meet the tolerance requirements, using the positioning mechanism and control system is quite complicated. Here is a simple and effective roller feeding cylinder slow accurate positioning mechanism. Tianshui Forging Machine Tool Plant in the copper and aluminum composite solar heat sink processing production line design and manufacturing process, the user made a technical parameters: Finished heat sink finished length of 1800mm, the tolerance of ± 1.0mm. From the surface to see this is a free tolerance, it uses the following program, that is, with a brake motor
