Description

A kind of stamping die of profile

Technical field

The utility model relates to sectional bar processing equipment technical fields, more specifically, it relates to a kind of stamping die of profile Tool.

Background technique

2012, with quickly propelling for the large-scale capital expenditure in China and process of industrialization, the aluminum profile whole industry Yield and consumption figure rapidly increase, and China also suddenly becomes maximum aluminum profile production base and consumption market in the world.

Corresponding different processing requests, aluminum profile needs, which are stamped, is made various forms, so needing to stamp machine, press machine exists When work, mold is needed to stamp, stamping die causes brokenly staking punch can be generated extremely strong reaction force by impacting with high pressure It is bad, and the service life of stamping die is not also high.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of structurally reasonable simple, it is practical Property it is strong, it is strong to delay pressure cushioning ability, reduces to the stamping die of punching press reaction force.

To achieve the above object, the utility model provides following technical solution:

A kind of stamping die of profile, including die body, die body include attic base and platen, have die cavity on platen, in attic base With central lumen and avris chamber, platen includes disc and piston body, and piston body includes the guide post for protruding into central chamber And the indoor ring of avris chamber is protruded into, the bottom of central lumen is equipped with cushion, and adding in avris chamber has liquid oil, the side of ring Wall is equipped with wavy diversion trench, and the base angle of avris chamber offers annular groove, and cushion is made of rubber, cushion Outer wall be equipped with several annular beads, the stepped setting of those annular beads.

By using above-mentioned technical proposal, when die body stress, the direction of impact force is downward, and platen is squeezed to attic base, living Cock body squeezes cushion, and since cushion is made of rubber, the ability with extremely strong slow pressure damping can be to impact force It buffers and then reduces reaction force.

In ring stress, the indoor liquid oil of ring meeting opposite side side chamber is squeezed, due to having diversion trench on the side wall of ring, Liquid oil can flow on diversion trench, realize the slow pressure damping to impact force, and then reduce reaction force, it is ensured that the peace of staking punch Entirely.

The utility model is further arranged to: being had on the decoupling rod for having insertion attic base, attic base on the disc For the blind hole of decoupling rod insertion, cap is set in blind hole, lubricant grease is equipped in cap, liquid is equipped between cap and blind via bottom Oil.

By using above-mentioned technical proposal, when mold is by punching press, decoupling rod downwards can be squeezed cap in blind hole, by There is liquid oil below cap, realize the slow pressure damping to impact force using liquid oil.The setting of lubricant grease further improves The floating capacity of cap, and then improve the slow pressure energy power to impact force.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The embodiments of the present invention are described further referring to Fig.1.

The present embodiment specific structure: including die body, die body includes attic base 2 and platen 1, has die cavity, attic base 2 on platen 1 Interior to have central lumen 201 and avris chamber 202, platen 1 includes disc 12 and piston body 11, and piston body 11 includes in protruding into Guide post 1a in chambers of the heart room 201 and the indoor ring 1b of avris chamber is protruded into, the bottom of central lumen 201 is equipped with cushion 4, side Adding in side cavity 202 has liquid oil 101, and the side wall of ring 1b is equipped with wavy diversion trench, and the base angle of avris chamber 202 is opened Equipped with annular groove, cushion 4 is made of rubber, and the outer wall of cushion 4 is equipped with several annular beads, those annular beads are in Ladder-like setting.

When die body stress, the direction of impact force is downward, and platen 1 is squeezed to attic base 2, and piston body squeezes cushion 4, by It is made in cushion 4 of rubber, the ability with extremely strong slow pressure damping can buffer impact force and then reduce reaction Power.

In ring 1b stress, the indoor liquid oil 101 of ring 1b meeting opposite side side chamber is squeezed, due to having on the side wall of ring 1b There is diversion trench, liquid oil can flow on diversion trench, realize the slow pressure damping to impact force, and then reduce reaction force, it is ensured that punching The safety of pressure head.

There is on the decoupling rod 3 for having insertion attic base 2, attic base 2 blind hole for decoupling rod insertion on disc 12, it is blind Cap 5 is set in hole, is equipped with lubricant grease in cap 5, liquid oil 102 is equipped between cap and blind via bottom.

When mold is by punching press, decoupling rod 3 downwards can be squeezed cap 5 in blind hole, due to having liquid oil below cap 102, the slow pressure damping to impact force is realized using liquid oil.The setting of lubricant grease further improves the floating capacity of cap, And then raising is to the slow pressure energy power of impact force.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model It protects in range.
