MULTI-STEP PROCESS PRESS SYSTEM

摘要

The present invention discloses a multi-step process press system which simultaneously processes a plurality of workpieces loaded on a plurality of workstations by one stroke while consecutively loading sheets onto a multi-step process press machine. The present invention includes a press machine, a plurality of press die sets, a sheet loading system, and a transfer feeder. According to the present invention, it is possible to consecutively and stably load sheets onto the workstations of the press machine by the sheet loading system, and sequentially perform press work on the loaded sheets by one stroke, thereby improving productivity, and remarkably reducing the cost of production. Also, there is a beneficial effect in which it is possible to efficiently and systematically perform sheet loading and press work.

主权项

1. A multi-step process press system comprising:
a press machine that includes a press frame which has an X-axis direction, a Y-axis direction, a Z-axis direction, and a press line aligned with the X-axis direction, a bolster which is installed on the press frame and has a plurality of workstations provided in series along the press line in order to perform press work on sheets such that complete products are produced from the sheets through blank workpieces, and a ram which is installed above the bolster so as to be able to linearly reciprocate along the Z-axis direction; a plurality of press die sets that is installed for press work at the workstations of the press machine, respectively, and each has a lower die installed on the bolster and an upper die installed on the ram; a sheet loading means that is installed at the upstream of the press machine, and loads the sheets onto the first workstation of the plurality of workstations; and a transfer feeder that is installed between the bolster and the ram of the press machine, and simultaneously unloads the blank workpieces loaded respectively on the workstations of the press machine, and loads the blank workpieces onto the downstream sides of the plurality of workstations.
