A rapid die replacement device for a numerically controlled punching machine

Abstract

The invention discloses a quick switching device for a mold of a numerical control punching machine, and relates to the technical field of numerical control punching. The quick switching device comprises a punching model, wherein the bottom surface of a punching model is fixedly provided with a switching mechanism; the bottom surface of the switching mechanism is fixedly provided with a fixing mechanism; and buffer mechanisms are fixedly mounted on both sides of the fixing mechanism. By means of the quick switching device, two sliding plates are driven to slide by two threaded pipes when two threaded rods rotating, so that an inserted rod is taken out from the inside of a fifth socket by sliding of the sliding plates; the function of switching the punching model at any time is achieved; the problem that the punching model not easy to replace is effectively avoided; the punching model can be fixed by the landing of a fixed plate; the stability of the punching model is effectively increased; and the elastic force of a first buffer spring makes the fixing plate play a certain buffering role when landing, so that the damage of the fixing plate is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of numerically controlled punching machines; in particular, it relates to a rapid mold replacement device for numerically controlled punching machines. Background technique [0002] CNC punching machine is the abbreviation of digital control punching machine; it is an automatic machine tool equipped with a program control system; the control system can logically process programs with control codes or other symbolic instructions; and decode them; so that the punching machine moves and processing parts. [0003] CNC punching machine can be used for processing various types of metal sheet parts; it can automatically complete a variety of complex pass and shallow stretch forming processing at one time; through simple mold combination; compared with traditional stamping; it saves a lot of mold costs; it can be used Low-cost and short-cycle processing of small batches and diversified products; large processing ra...
