Abstract

The invention discloses an arc punch die. The arc punch die comprises an upper template, a lower template, a male die and a female die; and a male die fixing plate is provided with a pressing device. The arc punch die is characterized in that: arc punching faces with different radiuses (R) are arranged at the periphery of the male die; arc faces which are matched with the punching faces of the male die are arranged at the periphery of an inner chamber of the female die; a female die fixing plate is provided with a workpiece positioning adjusting plate; the workpiece positioning adjusting plate is sleeved on the female die; a circular recess is formed around the female die and sleeved in an adjusting positioning rod on the female die fixing plate and can be rotatably adjusted; and the workpiece positioning adjusting plate is provided with a workpiece positioning pin. A set of male die and female die can punch a plurality of different R angles; and the arc punch die is low in cost, high in production efficiency and convenient in use.

Description

The circular arc die cutting die

Technical field

The present invention relates to a kind of mechanical machine dies, particularly a kind of circular arc die cutting die.

Background technology

The sharp corner of the many parts in the engineering goods all needs to adopt the die-cut fillet that carries out of mould to filter, but the specification of existing die-cut R mould is single, and often the R angle on part is more, and sample diversified in specifications, finish the die-cut mould that needs plurality of specifications of a part, the cost height, production efficiency is low, uses inconvenient.

Summary of the invention

The objective of the invention is in order to overcome above-mentioned weak point, and provide a kind of can die-cut multiple different R angle, cost is low, production efficiency height, circular arc die cutting die easy to use.

The object of the present invention is achieved like this: the circular arc die cutting die comprises cope match-plate pattern, lower bolster, punch, die, cope match-plate pattern, wherein last fixed guide cover in the lower bolster, fixed guide post on another piece, matched in clearance between fairlead and the lead, pass through the punch retainer solid punch on the cope match-plate pattern, die shank on the punch passes cope match-plate pattern, be connected with material pressing device on the punch retainer, on the lower bolster by the fixing die of die block, it is characterized in that the punch periphery has die-cut of the arc of different R, die inner chamber periphery has the arcwall face that matches with the die-cut face of punch, workpiece location adjustable plate is arranged on the die block, on the adjustable plate of workpiece location the circular hole that matches with die is arranged, by circle hole sleeve on die, flush with the die upper end, on the workpiece location adjustable plate of die periphery circular trough is arranged, adjusting backstay more than two is arranged on the die block of corresponding circular trough, be inserted in the circular trough on the adjustable plate of workpiece location and regulate the rotatable adjusting in backstay upper end, on the adjustable plate of workpiece location the workpiece alignment pin is arranged.

The present invention is owing to adopt above design, and one group of protruding, die can die-cut multiple different R angle, and cost is low, and the production efficiency height is easy to use.
