Description
Technical field
The present invention relates in a kind of forcing press loading and unloading, particularly punch line for from a upper sequence to the workpiece transfer device of next sequence.Also the workpiece that can be used for separate unit forcing press or similar machine picks and places and transmits.
Background technology
Need multiple operation by metal tablet to the manufacture of shaping workpiece, wherein most important operation is punch forming.Metal tablet needs, through multiple continuous print forming step such as drawing, bending, perforate, deburrings, finally to obtain required shape in a press.The form of mould determines the shape of workpiece, and the mould of forcing press generally includes a patrix and a corresponding counterdie, and described mould moves relative to each other, and makes the workpiece stretch forming be placed between upper/lower die.Because the shaping of a workpiece needs to have come through multiple mould continuous print molding procedure, therefore need to arrange that multiple forcing press is to form punch line continuously, or adopt the forcing press comprising multiple mould.On the one hand, the production capacity of punch line or multimode stamping machine namely realizes Time dependent required for a shaping operation by the production capacity of forcing press.But on the other hand, described ability depends on again workpiece to a great extent from a forcing press station to the conevying efficiency of the next stop.Therefore, rapid transit system workpiece being automatically transported to the next stop from a forcing press station is importantly adopted.
In punch line, the workpiece Transfer method between adjacent forcing press, has robot method of shipment or conveyer mode.So-called robot method of shipment is the carrier robot arranging joint type between adjacent forcing press, utilizes in the forcing press of this carrier robot the past one procedure and takes out workpiece, this workpiece is sent into the forcing press of next operation simultaneously.But robot method of shipment must be followed the respective intermittently moving of adjacent forcing press and be transported workpiece, and must avoid the interference with metal die etc. when workpiece transports.Therefore, the shortcoming of existence is the travelling speed high speed that can not make workpiece, thus limits the raising of whole line productive temp.In addition, when adopting robot method of shipment, transport its teaching difficulty in track and debug time is long in teaching.Conveyors carry mode is divided into single armed feeding and both arms feeding two kinds of modes, single armed feeding arranges a set of pay-off between adjacent forcing press, arm for taking material extend into forcing press die cavity and takes out workpiece from press ram dead ahead, this workpiece is sent into the forcing press die cavity of next operation simultaneously.Both arms feeding is that the left and right sides between adjacent forcing press arranges a set of feeding arm respectively, and two cover feeding arms are connected by a cross bar, and feeding arm drives cross bar to complete the transport of workpiece.
Summary of the invention
