Abstract
The utility model discloses a punching mechanism for a punching die, which comprises a base. A punch seat and a punching die seat are arranged on the base, a pressure plate is arranged on a punch fixing plate which is arranged on the punch seat, a punch is arranged in the punch fixing plate and penetrates out of the pressure plate, a positioning block used for positioning work pieces is arranged on a mounting step which is arranged on the punching die seat, and a first die button hole is arranged in the first die button which is arranged in the positioning block. A die button block is arranged on the punching die seat, a second die button is arranged in the die button block at a position corresponding to the first die button, a first slug hole is arranged on the punching die seat at a position corresponding to the second die button, and a waste passage communicated with the slug hole is arranged on the punching die seat. Wastes of a first punched hole are compressed through the first die button hole into a punch diameter required by a second hole to be punched, so that lateral punching of the second hole can be completed. Production efficiency is improved and production cost is reduced while coaxial tolerance dimension of diameters of the two holes is guaranteed.
Description
Technical field
The utility model relates to a kind of diel, refers more particularly to a kind of punch mechanism of punching die.
Background technology
The punch mechanism of common punching die once can only be on product through hole of punching out; When needing the processing coaxial through-hole on the adjacent two boards that runs into product; It generally is the required through hole of difference punching out on biside plate; But this processing method not only operating efficiency is low, and when being used for the requirement on machining accuracy high product, the axiality in two holes, processing back does not usually reach designing requirement.
The utility model content
The utility model technical problem to be solved is: provide a kind of can be on U type spare the punch mechanism of the punching die efficiently of two coaxial through-holes of punching press once.
A kind of punch mechanism of punching die comprises base, is movably arranged on the punch holder on the base and is fixedly installed on the die shoe on the base that described punch holder is provided with the drift fixed head; Be provided with drift in the drift fixed head, described die shoe is provided with installation step, and the installation step bottom surface is provided with the locating piece that is used to locate workpiece; Be provided with the first mould button in the locating piece; Be provided with the first mould buttonhole in the first mould button, the first mould buttonhole drift end diameter is greater than other end diameter, and the installation step side is provided with mould button piece on the die shoe; Be provided with between mould button piece and the locating piece and put the material gap; Be provided with the second mould button with the corresponding position of the first mould button in the mould button piece, be provided with the second mould buttonhole of diameter greater than the big end of the first mould buttonhole in the second mould button, die shoe is provided with the slug hole that is connected with the second mould buttonhole; Also be provided with the waste channel that is communicated with slug hole on the described die shoe; Punch holder one side at locating piece on the described die shoe is provided with holding pad, is provided with between holding pad and the locating piece to put the material gap, and holding pad is provided with bore of the punch.
Described locating piece is provided with the adjustment piece in order to the adjustment location of workpiece.
Described punch holder upper edge pressing direction is provided with nitrogen spring.
Be provided with the drift backing plate between described punch holder and drift fixed head.
Described die shoe and mould button interblock are provided with cushion block and adjustment backing plate, and cushion block is respectively arranged with the through hole that connects with the second mould buttonhole and slug hole with adjusting on the backing plate.
The described second mould buttonhole is a bellmouth near the part of die shoe end.
The utility model has the advantages that: because the first mould buttonhole drift end diameter is greater than other end diameter; Needed punch diameter size is carried out second hole of side blow in the time of can utilizing the waste material of first punching to be compressed into second punching through the first mould buttonhole; Reduced stamping procedure; In the axiality tolerance dimension that guarantees two apertures, improved production efficiency, reduced production cost.
