Piercing die for simultaneously punching five direction holes by using two different cam mechanisms, and operating method thereof

Abstract

The invention relates to a piercing die for simultaneously punching five direction holes by using two different cam mechanisms, and an operating method thereof, and is characterized in that the piercing die for simultaneously punching five direction holes by using two different cam mechanisms comprises an upper die, a lower die, and a piercing lower die sleeve disposed over the middle of the lower die; a to-be-punched hood-shaped thin shell workpiece is disposed at an upper portion of the piercing lower die sleeve; a lower portion of the upper die is provided with motion cam punches and a single-action double-faced cam punch; the lower die is provided with three radial punch pin sliding seats which can be driven by the three sets of motion cam punches to move and a couple of opposite punch pin sliding seats which can be driven by the single-action double-faced cam punch to move; inner end portions of the radial punch pin sliding seats are provided with radial hole punch pins; and inner end portions of the opposite punch pin sliding seats are provided with opposite hole punch pins. Position accuracy requirements of to-be-machined holes of the hood-shaped thin shell workpiece can be satisfied.

Description

[0001] Technical field: [0002] The invention relates to a punching die which uses two different cam mechanisms to simultaneously punch holes in five directions and a working method thereof. [0003] Background technique: [0004] In the actual production of cylindrical sheet metal (stamping cover-shaped thin shell workpiece), it is usually necessary to punch holes in multiple directions on the processed cylinder. When punching cylindrical parts, the traditional method is to use wedge hedging Moreover, for porous products, the position accuracy requirements of the processed holes cannot be guaranteed at all, which is not only time-consuming and laborious, but also the accuracy often fails to meet the requirements, thus easily causing many waste products. [0005] Invention content: [0006] The purpose of the present invention is to provide a punching die and its working method for simultaneously punching five-direction holes with two different cam mechanisms. The punchin...
