ABSTRACT:
A transfer press is disclosed which has a pair of parallel spaced transfer bars for indexing work through a succession of press stations. Each transfer bar consists of, typically, five segments separably joined end to end. For longitudinally moving the constituent segments of each transfer bar away from one another, as for the change of press dies, there are provided a one-way splitting mechanism which moves a terminal segment of each transfer bar away from the next, and a two-way splitting mechanism which separates the central segment of each transfer bar away from the oppositely adjoining ones. The one-way and two-way splitting mechanisms are approximately analogous in construction, each having a splitter pin which is movable up and down into and out of engagement with the desired transfer bar segment and which is further movable with the transfer bar segment for separating it from the neighboring segment or segments. The one-way splitting mechanism incorporates a dual cylinder assembly, and the two-way splitting mechanism a triple cylinder assembly, for moving the splitter pin as above. Additional embodiments are disclosed wherein each transfer bar is split into three and seven segments respectively.
