Abstract
The utility model relates to a can prolong punching handle life's novel mould on drift. The mould is equipped with mounting hole to down including punching handle and drift at the punching handle lower extreme from last on the drift, and the briquetting is placed in the mounting hole, and the nut passes through threaded connection with punching handle installation pore wall, and drift, briquetting pass the lock nut centre bore, and end cross -sectional area is big with drift and punching handle in close contact with, the briquetting cross -sectional area specific impulse top of the head for the upper and lower face of briquetting. With making it independence and punching handle, drift contact among the built -in punching handle of briquetting. The briquetting can be changed alone, and does not influence punching handle's result of use (the briquetting improves hardness behind thermal treatment, briquetting also difficult production warp).
Description
Technical field
This utility model is related to a kind of stamping mold, specifically a kind of Novel flushing that can extend die shank service life
Upper die.
Background technology
At present, the Novel flushing upper die of press machine typically adopts overall structure on market, using a period of time die shank
Top long-time is impacted by drift, and die shank can be deformed needing to repair or changing, and need the die shank for more renewing, and die shank is more
Change and once then make whole die shank and lose use value, cause to waste, increased use cost.And during workman's replacing die shank waste
Between, reduce production efficiency.
Being badly in need of one kind now can extend die shank service life, the Novel flushing upper die of improve production efficiency.
The content of the invention
The purpose of this utility model is to provide for a kind of simple structure, easy to use, effectively extends die shank service life, enters
And the Novel flushing upper die of improve production efficiency.
The technical solution of the utility model is：
Novel flushing upper die includes from top to bottom die shank and drift, and in die shank lower end installing hole is provided with, and briquetting is placed on peace
In dress hole, nut is installed hole wall and is threaded connection with die shank, and drift, briquetting pass through locking nut centre bore, briquetting above and below
It is in close contact with drift and die shank, briquetting cross-sectional area is bigger than punch tip cross-sectional area.
The beneficial effects of the utility model:
1st, a briquetting is designed, independent and die shank, punch. contact will be allowed in the built-in die shank of briquetting.Briquetting can individually more
Change, and do not affect the using effect of die shank（Briquetting after heat treatment improves hardness, and briquetting is also less susceptible to be deformed）；
2nd, after mould uses some time, if if briquetting is deformed, it is only necessary to change briquetting, whole die shank need not
Change, die shank can increased the service life of die shank without frequently changing again, reduce workman's lead-time, improve
Production efficiency.
Description of the drawings
Fig. 1 is the application overall structure diagram.
Specific embodiment
This Novel flushing upper die is made up of die shank 1, briquetting 2, locking nut 3, drift 4 successively from top to bottom, under die shank
End is provided with installing hole, and briquetting is placed in installing hole, and nut is installed hole wall and is threaded connection with die shank, and drift, briquetting are passed through
Locking nut centre bore, briquetting above and below is in close contact with drift and die shank, and briquetting cross-sectional area is than punch tip cross-sectional area
Greatly.When work is punched, lathe slide block drives overall Novel flushing upper die to do work downwards, and the cutting edge face of drift 4 connects with leaf spring
Punching is touched, produced counteracting force is passed up to briquetting 2 by drift 4, then power is passed to die shank by briquetting 2, finally
Lathe slide block is transmitted the force to by die shank to offset.Because briquetting 2 is to improve hardness through quenching, so wear-resisting, resistance to compression, plus
Briquetting 2 diameter it is larger than the diameter of drift 4, reaction forces can be passed to die shank 1, make the unit of die shank 1
Area stress reduces, and cannot use so as to reduce die shank compressive deformation.If briquetting 2 deforms after long-time is extruded, can
Briquetting 2 is changed to dismantle locking nut 3, directly employing is threadedly coupled for locking nut 3 and die shank 1, be easy to drift 4 and briquetting 2
Locking, installation and dismounting.
The application structure design saves the manufacturing cost of die shank, improves the utilization rate of drift, if in use briquetting is produced
Deformation, it is only necessary to change briquetting, then whole die shank is not changed.It is convenient to check whether briquetting deforms when drift is changed.
Claims (1)
