Description
Technical field
This utility model belongs to mechanical manufacturing field, is specifically related in cold stamping pilot pin in uncoiling blanking mould.
Background technology
Along with modern production development, the also development of automobile industry is swift and violent, and our daily come into by automobile
In life.Car panel die industry becomes the backing that automobile manufacture industry is powerful, and supply is the most all increasing, existing
In producing for panel beating cold stamping, common manual line is the most gradually eliminated by industry, the substitute is automatization and transmission mask
Production line.Automatization and transmission mask production line produce and are all made up of a production line, and mechanical hand, robot folder send part,
Overall process need not manually participate in substantially, and production efficiency is greatly improved, and product quality improves further, reduces manually-operated mistake
Difference, reduces follow-up workload, cost-effective, improves profit.And wherein for automatization's stable mass life of blanking operation
Produce and probability is provided, be uncoiling blanking mould and uncoiling blanking production line.Uncoiling blanking mould is derived from transmission mask and produces
Line, production process is similar with multistation, and production process can simply be described as: coiled strip is sent to mould by exhibition material machine
In, and tablet is fed by the program being previously set, the distance that we feed every time is called its step pitch, step by step, in proper order
Progressive, to the last go out finished product, transmission band send board, and then vanning, whole work are all to be completed by the program set.Cause
Step pitch for transmitting has certain error, at this moment needs exist for the device of correcting location, is arranged in the position of a work step punching
Put, after work step utilize this hole, metal plate part is corrected, position with reduce charging step pitch error.As leading in prior art
The pilot pin of the device just positioned, for being fixed on the pin in the upper molded plate of blanking die or insert, although can complete correcting
Location, but owing to burr or alignment pin clearance issues, metal plate part and pilot pin can not separate at once, metal plate part can be stuck on pilot pin,
Namely what is often called gets stuck, strip phenomenon.Thus the work efficiency of transfer matic mould can be affected, upset work rhythm, affect product matter
Amount, even can mold damage itself, affect mold work efficiency and work quality problem.
Utility model content
This utility model purpose is to provide a kind of self-discharging pilot pin, uncoiling blanking in cold stamping, overcomes existing
The disadvantages mentioned above that pilot pin exists.
Self-discharging pilot pin of the present utility model, including the cylindrical pilot pin pin with conehead, improvements introduced is:
There is ring convex in the middle part of pin, on ring is convex, has several, ejector pin pilot hole that circle distribution, through ring convex coaxial with pin, ejector pin
Pilot hole has move with hole coordinate, tail end has the ejector pin of shoulder, the convex above section of ring at pin has the pressure being enclosed within pin
Spring, compression spring pressure holding, on the shoulder of ejector pin, is provided with the fixed cover surrounding spring outside spring, on fixed cover, there is pin at the end
Punched out, there is spring collar fitting recess the pin end passing the end on fixed cover, is provided with fixing lock set in collar fitting recess
The elastic wire collar being scheduled on pin, springlock is scheduled on pin by the fixed cover being locked on pin by steel wire collar.
Self-discharging pilot pin of the present utility model preferred mounting means on upper molded plate has:
A, locking type: have on ring projection face and lock screw cylinder head of a nail side and match, start from the convex lower end of ring
Cylinder groove, is assembled on upper molded plate by locking screw；
B, forced: on ring is convex, to form the shoulder of evagination, by having insert and the insert trip bolt of ring salient mounting distribution
Pilot pin press-in is assembled on upper molded plate.
Pilot pin of the present utility model is not limited to both the above mounting means, however not excluded that ensureing precision, affecting top
Use in the prior art on the premise of pin action and the mechanical fasteners mode of prior art enlightenment.
Work process of the present utility model is: upper mold moves down, pilot pin first guide, mold work, and bear down on one under tablet pin,
Ejector pin moves down, and ejector pin moves down middle compression spring accumulation of energy, treats that mold work is complete, and upper mold upwardly opens, and compression spring discharges, transmission
To ejector pin material returned power, ejector pin material returned power acts on the metal plate part of border, hole, location.Overcome between metal plate part and pilot pin because of burr etc.
The jam that reason is formed, makes metal plate part and pilot pin be instantly separable from.
Good effect of the present utility model is: former pilot pin, through transformation, is additionally arranged ejector pin in pin working portion periphery,
Pin bottom suit promotes the spring of ejector pin, spring provide stripping force, and when metal plate part gets stuck strip, the pressure of spring is by top
Pin passes to metal plate part uniformly, makes metal plate part by uniform material returned power around hole, location, so that metal plate part is smooth and correcting
Pin departs from, it is ensured that the production of blanking die safety and stability, has not only acted as the effect of correcting location and has eliminated what metal plate part produced
The strip that gets stuck phenomenon so that mould produces smooth, stable, safety, is effectively improved product quality, improves production efficiency.
