Abstract
The present invention relates to a kind of threeways to be cold-pressed plunger chip die, including punch ontology and pedestal, punch ontology include punch and jumper bar；If the smaller diameter end and larger diameter end of jumper bar are separately connected punch and pedestal by bolt stem；It is equipped with circular groove on the top of punch；Bolt enters from the circular groove bottom on the top of punch and the bottom of pedestal respectively, is connect with jumper bar；It is equipped with O-ring seal between jumper bar and punch, between jumper bar and pedestal.The present invention, which has, to be changed simple, reduces material, human cost and the good advantage of sealing effect.
Description
Technical field
The present invention relates to a kind of threeway plunger chip dies, more particularly to one kind being suitable for cold extrusion threeway plunger chip die.
Background technology
Threeway cold moudling processing needs the forging mold using various specifications high intensity, and traditional plunger chip die is by punch
Ontology and pedestal composition, as shown in Figure 2.Punch ontology is easily damaged in Reusability, and replacement frequency is relatively high, and punch sheet
Body needs hardness high, the good material of anti-fatigue performance, therefore replacement cost is higher；And in the existing structure, punch ontology with
The connection of pedestal is to connect to be influenced by connection structure by the bolt of base bottom, often replaces a punch ontology and is required for
Package unit is dismantled, then bolt is unclamped from base bottom and removes the punch ontology re-attached installation needed replacing, by
In single unit system heavier-weight, dismounting is extremely inconvenient, wastes a large amount of manpower.In addition, since punch ontology is in Reusability
The part being easily damaged is usually in the actual use part of punch ontology front end, and rear end non-use part is not damaged substantially
It is bad, once the damage failure of punch ontology fore-end is to cause the very big waste on material with changing entire punch ontology.
Invention content
Against the above deficiency, it is simple and can reduce the threeway of cost cold pressing punch mould to provide a kind of assembly and disassembly methods by the present invention
Tool.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that.
A kind of threeway cold pressing plunger chip die, including punch ontology and pedestal, punch ontology include punch and jumper bar；Jumper bar
If smaller diameter end and larger diameter end are separately connected punch and pedestal by bolt stem；It is equipped with circular groove on the top of punch；Spiral shell
Bolt enters from the circular groove bottom on the top of punch and the bottom of pedestal respectively, is connect with jumper bar；Between jumper bar and punch,
O-ring seal and positioning device are equipped between jumper bar and pedestal.
Further, the O-ring seal between jumper bar and punch, between jumper bar and pedestal is equipped with 2, rushing
If 2 O-ring seals between bar and punch are respectively provided at the medial and lateral that bolt stem surrounds circle；2 between jumper bar and pedestal
If a O-ring seal is each provided at the inside that bolt stem surrounds circle.
Further, on the joint face being connect with jumper bar on the joint face being connect with punch on jumper bar, on pedestal
The O-shaped seal groove being equipped with, O-ring seal are arranged in O-shaped seal groove.
Further, the positioning device between punch and jumper bar, between jumper bar and pedestal, including locating slot and fixed
Position block.
A kind of threeway disclosed by the invention is cold-pressed plunger chip die, and punch is the actual use part of plunger chip die, is easy
The component of damage, replacement frequency are high；And connecting component only when need replacing punch model ability of the jumper bar as punch lower end
It needs replacing；Pedestal may be reused；Punch body part in the prior art due to being split into punch and punching by the present invention
Two parts of bar, punch is high using hardness, the good material of anti-fatigue performance, and jumper bar then uses general hardness identical with pedestal
Material, the material cost of the plunger chip die reduced in this way.The present invention only need to change punch after punch damages, without damaging
Jumper bar part be then not necessarily to compared with the punch that changes, and change needs the punch ontology changed in the middle with the prior art, shared by
The proportion of material is fewer, so reducing the cost for changeing material again.In addition, the bolt that punch is connect with jumper bar be from
Punch tip is connected to jumper bar, so when needing to change punch, bolt only need to be twisted from punch tip with regard to replaceable punch, and
Needs are dismantled package unit just replaceable when without changeing punch ontology as the prior art, so punch is made to change simply
Change.Each joint face of the present invention uses dual-seal circle simultaneously, makes sealing effect more preferably.In conclusion the present invention's is excellent
Point is to change easy to operate, and material and human cost reduce and sealing effect is good.
