Sectional machining structure of large stamping die set

Abstract

The invention discloses a sectional machining structure of a large stamping die set. The sectional machining structure comprises a plurality of sub die plates for machining the large stamping die set, wherein every two adjacent sub die plates are detachably and fixedly connected into a female die plate, and at least one common locating reference is arranged on each of the opposite end faces at intervals when every two adjacent sub die plates are connected. The structure meets machining precision requirements, can effectively reduce the machining cost and the machining difficulty, improve the machining safety at the same time, is convenient to carry, is applicable to general machining centers, and is not limited to an ultra large machining center.

Description

technical field [0001] The invention relates to a large stamping die frame, in particular to a segmented processing structure of the large stamping die frame. Background technique [0002] Stamping mold base is the most typical functional part of forging machine tools, and it was the first to realize standardized and specialized production. The punching, blanking, stretching, cutting and other stamping processes on the machine tool press are inseparable from the stamping die. The punch and die of the working part of the stamping die are installed on the stamping die frame. Different stamping processes require different punches and dies, but the same stamping die frame can be used. The stamping die set includes upper template, lower template and guide pillars, guide sleeves and other guide parts. When the stamping mold base is processed, it is necessary to ensure that the hole position accuracy of the guides installed on the mold base meets the requirements, but for large s...

Problems solved by technology

When the stamping mold base is processed, it is necessary to ensure that the hole position accuracy of the guides installed on the mold base meets the requirements, but for large stamping mold bases such as 100T*4900W*700H large stamping mold bases, it is necessary to ensure that the guide pieces on it The accuracy of the hole position requires the purchase of a whole template as required, which must be processed by a super-large machining center. Due to the limitations of the stroke and the workbench, the general machining center cannot process it.

Moreover, the handling of the whole template is extremely inconvenient, the processing is difficult, and there are potential safety hazards in handling, which leads to low processing efficiency and increases production costs
