Combined quick-change nest hole stamping die

Abstract

The invention relates to a combined quick-change nest hole stamping die. The combined quick-change nest hole stamping die comprises an upper die and a lower die, a grinding head is arranged at the head of the top end of the upper die according to the size of a nest hole, the core of the grinding head is a hollow connector, an elastic block is arranged in the middle of the upper die, and the upper die is provided with a die handle; and the lower die is matched with the upper die, the lower die is mainly of a modular structure and is provided with a replaceable bottom plate, a guide plate is arranged on the bottom plate, a positioning pin is arranged in the width direction of the guide plate, matched dovetail grooves are formed in the two ends of the length direction of the guide plate, and the dovetail grooves can achieve the quick splicing, positioning and guiding functions of a plurality of lower die modules. In addition, the side face of the guide plate is provided with a bolt set and cushion blocks which are used for adjusting the intervals of different modules, the quick adjusting function can be achieved when parts with unequal pit intervals are produced in batches, the problem that multiple times of lineation, alignment and adjustment are needed in traditional batch production of indentation is solved, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of special tooling design, and more specifically relates to a combined quick-change socket punching die. Background technique [0002] Traditional dimples are often manually pressed or the radius of the pit that needs to be pressed is small. When the center of the bottom of the pit that needs to be pressed needs to be drilled, it is often difficult to ensure the center position of the semi-arc-shaped pit, and the original There may be a certain degree of deformation of the steel plate around the pit after pressing the pit. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stamping die suitable for mass production and used for stamping semi-arc shaped dimples with holes at the bottom. [0004] The technical solution adopted by the present invention to solve the technical problem is: to construct a combined quick-change socket stamping die, includ...
