Automatic die rotating and replacing device for bending machine

Abstract

The invention provides an automatic die rotating and replacing device for a bending machine. The automatic die rotating and replacing device comprises a die turning mechanism and a die backstop and carrying mechanism which are arranged between a left vertical plate and a right vertical plate. A die turning mechanism left rotating wheel disc and a die rotating mechanism right rotating wheel disc are connected with a coupling device through a rigid connection shaft and driven by a right rotating disc shaft drive mechanism, and synchronous rotating of the left rotating wheel disc and the right rotating wheel disc is guaranteed; each rotating wheel disc is provided with a plurality of hanging shafts capable of achieving autoroatation, the hanging shafts correspond to each other in a synchronizing mode on the same station on the two wheel discs, a bending machine die is hung on the rotating wheel discs through the hanging shafts, the two rotating wheel discs are connected with the coupling device through the rigid shaft to achieve synchronous rotating, and the bending machine die is always kept in the vertical position and free of overturning and leftward and rightward moving in the rotating process of the rotating wheel discs; the die backstop and carrying mechanism comprises two blocking fingers playing roles in die positioning and die carrying respectively. The device is economical and practical, easy to operate and high in universality, the die replacing time is saved for users, and production efficiency is improved.

Description

technical field [0001] The invention relates to an automatic rotary mold library and a mold changing device, in particular to an automatic rotary mold changing device used on a numerically controlled bending machine. Background technique [0002] CNC bending machine is the key equipment for sheet metal processing. Users have continuously improved the efficiency of bending process, and the styles of bending workpieces are increasing. The types of molds required are also increasing and the molds are large and heavy. Therefore, bending machine molds Efficiency in storage and die change is becoming more and more important. At present, the conventional mold library device is a mold cabinet frame. The mold is placed on the cabinet frame, and the mold cabinet frame is placed outside the host frame. The span is large. The traditional method of transporting molds is to manually carry and change molds. When encountering a mold with a very large mass, it needs to be operated with the...
