A metal mold punching device

Abstract

The invention relates to the technical field of hardware moulds, in particular to a hardware mould punching device comprising a machining table, a lifting screw sliding table, a locating mechanism, aclamping mechanism, a lifting mechanism, a rotating mechanism, a first manipulator, a second manipulator and an operating board; the top of the machining table is provided with a mounting plate, and the lifting screw sliding table is installed on the mounting plate; the lifting screw sliding table is provided with a mounting bracket which is provided with a punching motor, and the punching motor is provided with a fixing ring; the fixing ring is internally provided with a drill bit part, and the machining table is provided with a mounting groove; the locating mechanism is installed in the mounting groove, and the clamping mechanism is installed on the locating mechanism; the lifting mechanism is installed on the operating board, and both the rotating mechanism and the first manipulator areinstalled on the lifting mechanism; and the second manipulator is installed on the mounting bracket. According to the hardware mould punching device, automatic replacement of the drill bit part is achieved; and through the locating mechanism, drilling of multiple positions of hardware is facilitated, and moulds in different sizes can be fixed through the clamping mechanism automatically.

Description

technical field [0001] The invention relates to the technical field of hardware molds, in particular to a punching device for hardware molds. Background technique [0002] Metal stamping die is a machine for stamping and producing sheet metal parts. It has the advantages of high production efficiency and short production cycle. At the same time, because many holes are needed on the metal mold to facilitate the production of hardware products, so the hardware mold punching device has appeared in people's field of vision; The hole device often can only punch holes for a mold of one size, so it is inconvenient when punching a variety of different types of molds; on the other hand, because the size of the punched holes on the mold often needs to be changed, and The existing punching device is more troublesome when replacing drill bits of different sizes. [0003] The patent number is CN208276208U, a metal mold punching device, including lifting rod, fixed rod, motor, base, ba...

AI Technical Summary

Problems solved by technology

[0004] There are still many problems in the above-mentioned metal mold punching device: 1. The first positioning rod and the second positioning rod are limited in the fixed ring by a spring, and the spring force of the spring must be large enough to realize it. One and two positioning rods may have the problem that the positioning pin cannot completely disengage from the fixing hole, and squeezing it by hand is also dangerous

2. Manually turning the screw to change the distance between each fixing plate can fix different molds for consignment sales, but the fixing efficiency of this method is too slow, and manual operation is also dangerous

3. When the device punches different positions of the hardware, it is manually adjusted, and the efficiency of manual adjustment is slow, which reduces the efficiency of punching
