DEVICE FOR ACCURACY MEASURING OF PRESS MACHINE

摘要

The present invention relates to a punch press module mounted on a press device for measuring precision and, more particularly, to a punch press module installed on one side of a sub die to press one side in the transverse direction of the punch in the longitudinal direction; A displacement measuring module installed on the lower die facing the punch pressing module and measuring a displacement of one side of the punch generated by the punch pressing module; And a controller for receiving and storing the load value applied by the punch pressing module and the measured displacement value measured by the displacement measuring module in correspondence thereto.Accordingly, by measuring the mechanical precision generated in the press machine, in particular, the mechanical precision generated between the lower die and the punch, it is possible to find the cause of the defect in the plate material molding, whereby the precision press machine is stably and precisely It is possible to produce a product and provide a basis for analyzing the cause of low precision of a press machine with a low precision.;
