A replaceable swing punching die with circular tube compound drive

Abstract

The invention relates to a circular tube double-drive replaceable swing punching die, which includes a positioning and fixing upper template, a positioning lower template, a special-shaped driving device, a special-shaped driving device, a locking brake block driven in different directions, a directional reset fixing plate, and a special-shaped driving device. The locking brake block is fixed to the bottom of the positioning upper template, and two sets of different positioning seats are fixed on the inner side of the two sets of directional reset fixing plates. The bottom of the seat is provided with a pressure-type mandrel sliding guide positioning seat, the bottom surface of the different direction positioning seat is connected and fixed with a positioning lower template, and the outer side of the driving guide rod is provided with a punching mandrel knife edge. The invention reduces the labor intensity of employees, achieves the purpose of reducing consumption and increasing efficiency, shortens the production cycle, improves production efficiency, reduces the cost of equipment and manpower, realizes automatic welding, is simple to operate, and is convenient to install. To achieve the purpose of safe production advantages.

Description

technical field [0001] The invention relates to a die for cutting circular arcs of circular pipes, in particular to a double-drive and changeable swing punching die for circular pipes. Background technique [0002] At present, the circular arc of the circular pipe notch passes through a simple punching die, and is cut and punched twice. At the center of the circular arc, the burrs of the incision are large, and it is difficult to ensure that the arc is perpendicular to the pipe. The cut arc does not fit well with other workpieces and the gap is too large. It is impossible to carry out automatic welding, and the product processing cannot meet the requirements of the drawing. The poor fit of the incision arc causes the gap to be too large during welding, which cannot be welded at one time. The strength is high, the work efficiency is low, and the stamping effect is not good, the error range is large, the product can easily fail to meet the requirements, and the old-fashioned m...
