Description
Technical field
The utility model relates to a kind of stripper apparatus, relates in particular to a kind of interior disposable stripper apparatus of external diameter frock.
Background technology
The moulding of existing special-shaped ring loose tool annular forging piece generally needs twice demoulding, namely to internal diameter frock and the demoulding successively of external diameter frock, yet there are following 2 deficiencies in existing stripping means: one, internal diameter frock and external diameter frock need be operated the demoulding successively twice, operating time is longer, and production efficiency is lower, and owing to the operating time is long, can cause the annular forging piece temperature significantly to reduce, increase demoulding difficulty greatly and reduced demoulding quality; Its two, existing stripper apparatus is generally easy auxiliary mould, and is not high with the interlock degree of shaping frock, demoulding frock biasing easily takes place in knockout course and the annular forging piece of damaging influence product quality, and the bigger potential safety hazard of existence.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of external diameter frock in the disposable demoulding, production efficiency height, disposable stripper apparatus of interior external diameter frock that demoulding quality is good, safety coefficient is high realized is provided.
The technical solution of the utility model is achieved in that a kind of interior disposable stripper apparatus of external diameter frock, it comprises demoulding piece, the bottom knockout piece, bucket is shaped, the moulding drift, described moulding drift is positioned at the bucket that is shaped, be provided with annular forging piece from top to bottom between described moulding drift and the shaping bucket, gasket ring, described go up demoulding piece be positioned at the bucket that is shaped directly over, described bottom knockout piece be positioned at the bucket that is shaped under, described upward demoulding piece is internal diameter band step annular element, the upper end of described moulding drift, the upper end of annular forging piece all can embed in the demoulding piece, described bottom knockout piece is external diameter annular element with the level, the top external diameter of described bottom knockout piece is less than lower outer diameter, the outer wall of described moulding drift lower end caves inward and encloses draw-in groove with the inwall formation one of gasket ring, the shape of described bottom knockout piece upper end and draw-in groove coupling also can embed draw-in groove, and the lower outer diameter of described bottom knockout piece is greater than the internal diameter of gasket ring.
Preferably, the described top internal diameter of demoulding piece of going up is less than the bottom internal diameter, the upper end shape of described moulding drift and the shaped upper part of last demoulding piece coupling also can embed described top of going up demoulding piece, the external diameter of described annular forging piece is greater than last demoulding piece top internal diameter and less than last demoulding piece bottom internal diameter, the shoulder height of described bottom knockout piece is greater than the shoulder height of last demoulding piece.
Preferably, also comprise brill, press following table on the press, the described demoulding piece of going up is arranged on the lower surface of boring on the press, and described bottom knockout piece is arranged on the upper surface of press following table.
The beneficial effect of the disposable stripper apparatus of external diameter frock is in the utility model: bottom knockout piece upper end accurately embeds draw-in groove, the moulding drift is separated with the annular forging piece demoulding, when bottom knockout piece external diameter step surface contact gasket ring, the bucket that will be shaped separates with the annular forging piece demoulding, last demoulding piece provides the demoulding to dodge the space for moulding drift and annular forging piece, can make the inside and outside frock of annular forging piece realize the disposable demoulding like this.Become once by twice demoulding, its production efficiency is improved, and its process time be shorter, in process, the temperature of annular forging piece during compared to twice demoulding the temperature fall of annular forging piece little, overcome the problem of demoulding difficulty, improved demoulding quality; In addition, bottom knockout in order to the disposable demoulding of external diameter frock in realizing is external diameter annular element with the level, integrated setting, make with the interlock degree of moulding frock higher, and below annular forging piece, be provided with gasket ring, make in knockout course, not to be prone to the annular forging piece of damaging, thereby influence the problem of product quality, improved safety coefficient.
