machine cabinets typically find use for larger machines or for applications requiring ancillary equipment such as shears, oilers, or material-support tables to be mounted to the servo feed. Cabinets typically are provided with motorized passline-height adjustment and no-tool press- mounts.
Material Support and Guidance
The catenary section is the mechanism used to support the continuous coil as it enters the servo roll feed. In conventional coil lines where the material is straightened ahead of the servo feed, the catenary section must be designed to properly support the strip as it draws from the slack loop. Lacking the necessary radius and arc of support will increase the potential to re-induce coilset or damage the material. Blanking oper- ations, as well as certain progressive- die applications that require the
in most servo roll feeds falls to the edge guide, which must maintain the continuous coil strip on
center and square to the feed rolls and die. Any misalignment of the strip to the feed rolls will result in tracking of the strip relative to the main axis of the feed rolls. Likewise, any misalignment of the strip to the die will increase the potential for
short feed lengths and mishits.
Like the other servo-feed devices, a variety of edge guides are available to meet the application and budget requirements for each job. Manually adjusted edge guides suit simple and dedicated feed setups; handcrank- adjusted edge guides find use for lines that require frequent changes in mate- rial width; and motorized and encoded edge guides often are used to free the operator from having to make these adjustments for each setup. MF
incoming coil strip to be flat, can be compromised by inadequate cate- nary-section design.
