Abstract
The invention discloses a kind of Split type die drift, including：Drift and the cavity plate being engaged with the drift, the drift include：Termination, be detachably connected to the termination together with cone, the termination is in cylinder, mounting hole is offered in the middle part of the termination, the upper end screw-in of the cone is fixedly connected in the mounting hole with the termination, and the contact position of the upper end of the cone and the upper and lower ends face of the termination is provided with rubber sheet gasket.By the above-mentioned means, it is of the invention, it is simple in construction, using termination and cone Split type structure, cone need to be only changed during replacing, use cost is reduced；Cone is externally provided with wear-resistant copper alloy coating simultaneously, can improve the anti-wear performance of cone, improves service life.
Description
Technical field
The present invention relates to technical field of mold, more particularly to a kind of Split type die drift.
Background technology
Drift is the important component of metal plate punching mould, is molded metal plate punching by the cooperation of drift and cavity plate, existing
Mold and punching head be generally integral structure, in punching course, drift can produce abrasion, so that punching precision can be reduced, and need
Drift is often changed, processing cost is considerably increased.
The content of the invention
The present invention solves the technical problem of a kind of Split type die drift is provided, existing mold drift can solve the problem that
The drawbacks described above of presence.
In order to solve the above technical problems, one aspect of the present invention is：A kind of Split type die drift is provided,
Including：Drift and the cavity plate being engaged with the drift, the drift include：Termination and the termination are detachably connected to one
The cone risen, the termination offers mounting hole in cylindrical in the middle part of the termination, the upper end of the cone is screwed in described
It is fixedly connected in mounting hole with the termination, the contact position of the upper end of the cone and the upper and lower ends face of the termination is provided with
Rubber sheet gasket.
In a preferred embodiment of the present invention, it is machined with female thread structure in the mounting hole.
In a preferred embodiment of the present invention, the upper end of the cone is machined with external thread structure.
In a preferred embodiment of the present invention, the female thread structure is meshed with the external thread structure.
In a preferred embodiment of the present invention, it is attached with wear-resistant copper alloy coating on the outer wall of the cone.
The beneficial effects of the invention are as follows：The present invention is simple in construction, using termination and cone Split type structure, is only needed more during replacing
Cone is changed, use cost is reduced；Cone is externally provided with wear-resistant copper alloy coating simultaneously, can improve the anti-wear performance of cone,
Improve service life.
Brief description of the drawings
Fig. 1 is a kind of structural representation of Split type die drift of the invention；
The mark of each part is as follows in accompanying drawing：1st, drift, 2, cavity plate, 3, rubber sheet gasket, 11, termination, 12, cone.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Referring to Fig. 1 embodiment of the present invention includes：
A kind of Split type die drift, including：Drift 1 and the cavity plate 2 being engaged with the drift 1, the drift 1 include：End
First 11, the cone 12 together with being detachably connected to the termination 11, the termination 11 is in cylinder, the middle part of the termination 11
Mounting hole is offered, the upper end screw-in of the cone 12 is fixedly connected in the mounting hole with the termination 11, the cone
The contact position of 12 upper end and the upper and lower ends face of the termination 11 is provided with rubber sheet gasket 3.
Wherein, female thread structure is machined with the mounting hole, the upper end of the cone 12 is machined with external thread structure, when
When the cone 12 is screwed into the mounting hole, the female thread structure is meshed with the external thread structure.
Preferably, wear-resistant copper alloy coating is attached with the outer wall of the cone 12, the wearability of cone 12 can be improved
Can, extend its service life.
The invention provides a kind of Split type die drift, only need to change using termination and cone Split type structure, during replacing
Cone, reduces use cost；Cone is externally provided with wear-resistant copper alloy coating simultaneously, can improve the anti-wear performance of cone, carry
High service life.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
