Description
Technical field
This utility model is related to the manufacturing technology field of Press Tools for Automobiles, more particularly to a kind of hot stamping die is scalable
Plunger mechanism.
Background technology
At present, when automobile panel uses hot forming tool molding, the operation for rushing aperture can be run into, now to drift
Require higher.Firstly, since drop stamping temperature is higher, drift generally requires the material with mechanics better performances and needs
Expensive coating.Secondly, the safety of drift and ruggedness also become the principal element of consideration.General cold-stamped punching
Head mechanism is not suitable for drop stamping punching.Tracing it to its cause is：The drift of traditional cold punching mechanism is long, and can not stretch automatically
Contracting, than larger, drift is susceptible to fracture wait and destroys the power applied to drift during matched moulds.Again as drift is typically mounted at
Mould, the dismounting of plunger mechanism are all not very convenient, if long the time required to burn failure is changed, affect work seriality and effect
Rate, while causing mold materials to waste, causes economic loss.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of drift is scalable, position is easily adjusted
It is whole, and ensure that stability and the safety of punching course, it is to avoid the hot stamping die retractable punch mechanism of burn failure.
This utility model solves its technical problem and is achieved through the following technical solutions：
A kind of hot stamping die retractable punch mechanism, it is characterised in that：Including drift sleeve, spring spool, drift, punching
Block, spring, guide pin bushing, base fixed block are hit, spring spool is coaxially fixedly mounted with drift barrel forward end, in drift sleeve and spring spool
Drift is co-axially mounted inside, punch head fixed installation impact block, the rear end of impact block are located in spring spool, the front end of impact block
Stretch out outside spring spool, the coaxial package spring between drift and spring spool, the mounting guide sleeve between drift and drift sleeve,
Base fixed block is fixedly mounted in the drift sleeve bottom end sidewall symmetry.
And, the impact block rear end is provided with shrinkage pool, is the T words of the drift at the top of T fonts at the top of described drift
At the top of type, clamp is fixed in the shrinkage pool of impact block.
And, the bottom of described drift sleeve bottom and base fixed block is located in same level, and the base is solid
Determine on block, to be formed with bolt mounting holes.
And, the rear end of described impact block is formed with limiting stand, and the limiting stand is located in the spring spool.
Advantage of the present utility model and have the beneficial effect that：
1st, this hot stamping die retractable punch mechanism, is co-axially mounted drift, drift in drift sleeve and spring spool
Front end fixedly mounts impact block, and the coaxial package spring between drift and spring spool is connected with stamping machine by base fixed block
Connect, realize the flexible of drift and reset, and forcer position is easily adjusted, and ensure that stability and the safety of punching course,
Waste of material is avoided, economic loss is reduced.
2nd, this hot stamping die retractable punch mechanism, impact block rear end are provided with shrinkage pool, are T fonts top at the top of drift
Portion, at the top of the T fonts of drift, clamp is fixed in the shrinkage pool of impact block, strengthens the connective stability of impact block and drift, is lifted
The stability and punching press effect of punching press.
The bottom of the 3rd, this hot stamping die retractable punch mechanism, drift sleeve bottom and base fixed block is located at same water
In plane, on base fixed block, bolt mounting holes are formed with, it is ensured that in punching course, drift is vertically lowered, it is ensured that punching press effect.
4th, this hot stamping die retractable punch mechanism, the rear end of impact block are formed with limiting stand, and the limiting stand is located at described
In spring spool, position-limiting action is played to impact block.
5th, rationally, drift has scalability to this utility model scientific structure design, has buffering effect in punching course
Really, it is to avoid burn failure, ensure that stability and the safety of punching course, it is to avoid waste of material, reduce economic loss.

Specific embodiment
Below by specific embodiment, the utility model is described in further detail, following examples be it is descriptive, no
It is determinate, it is impossible to which protection domain of the present utility model is limited with this.
A kind of hot stamping die retractable punch mechanism, its innovation is：Including drift sleeve 6, spring spool 2,
Drift 4, impact block 1, spring 3, guide pin bushing 5, base fixed block 7, are coaxially fixedly mounted with spring spool in drift barrel forward end, in drift set
Drift is co-axially mounted in cylinder and spring spool, punch head fixed installation impact block, the rear end of impact block are located in spring spool,
The front end of impact block is stretched out outside spring spool, the coaxial package spring between drift and spring spool, in drift and drift sleeve
