Description
Technical field
The drift technical field in diel is the utility model is related to, more particularly to a kind of removable punch structure.
Background technology
The metal parts in diel in machine tool, is called and rushes rod, red needle or punching pin, be mounted in punching press
Continuous stamping punching press is carried out on mould and thrusts operation, makes machined material that separation or plastic deformation occur, required for obtaining
Finished product or semi-finished product.With the development of society, increasing diel is used, drift is as essential one
Individual part, prolonged processing can cause the damage of drift, and at this time wanting replacing drift just needs to tear open whole diel
Open, bring very big inconvenience, therefore be necessary to provide a kind of removable punch structure.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided it is a kind of can conveniently dismounting can
The punch structure of dismounting.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of removable punch structure described in the utility model, includes drift body and drift set, the drift
Body one end is provided with drift threaded post, and the cylindrical wall of the drift body is provided with boss, and the boss surface is provided with convex
Ring；The drift set end surface is provided with the drift screwed hole to match with drift threaded post, the drift screwed hole bottom
Spring is fixedly installed, the spring one end is fixedly installed buffer board, and the drift set end surface is provided with and bulge loop phase
The bulge loop hole of matching；The drift threaded post bear against buffer board after being mutually threadedly coupled with drift screwed hole；Bulge loop one end is stretched into
Tight against the inner bottom surface that press against bulge loop hole behind bulge loop hole.
Further, the bottom surface in the bulge loop hole is provided with buffering ring flat-plate, and bulge loop one end is stretched into behind bulge loop hole tight against press against
Buffer ring flat-plate.
Further, the buffering ring flat-plate is made using elastomeric material.
Further, the cross section of the boss is in annular.
After said structure, the utility model has the beneficial effect that：A kind of removable drift described in the utility model
Structure, include drift body and drift set, drift body one end is provided with drift threaded post, and the cylindrical wall of drift body is set
There is boss, boss surface is provided with bulge loop；Drift set end surface is provided with the drift screwed hole to match with drift threaded post,
Drift screwed hole bottom is fixedly installed spring, and spring one end is fixedly installed buffer board, drift set end surface be provided with
The bulge loop hole that bulge loop matches；Drift threaded post bear against buffer board after being mutually threadedly coupled with drift screwed hole；Stretch bulge loop one end
Enter behind bulge loop hole tight against the inner bottom surface that press against bulge loop hole.When using the utility model, pass through rotary punch threaded post and drift
After screwed hole is mutually threadedly coupled, punching of just being stopped the rotation when after bulge loop hole is stretched into bulge loop one end tight against the inner bottom surface that press against bulge loop hole
Head thread post, now buffer board just compress spring, spring is occurred elastic deformation, spring and buffer board can play certain slow
Punching acts on, and effectively extends the service life of drift body and drift set；In addition, drift set is fixed in mold, drift body
With drift set using being threadedly coupled, so as to realize quick-replaceable drift body, removable drift is become, it is greatly convenient to use
Family uses.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Description of reference numerals：
1st, drift body；1-1, boss；1-2, bulge loop；
2nd, drift set；2-1, drift screwed hole；3rd, spring；4th, buffer board；5th, ring flat-plate is buffered.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of removable punch structure described in the utility model, includes drift body 1 and drift
Set 2, described one end of drift body 1 are provided with drift threaded post, and the cylindrical wall of the drift body 1 is provided with boss 1-1, described
Boss 1-1 surfaces are provided with bulge loop 1-2.
The drift covers 2 end surfaces and is provided with the drift screwed hole 2-1 to match with drift threaded post, the drift spiral shell
Pit 2-1 bottoms are fixedly installed spring 3, and described one end of spring 3 is fixedly installed buffer board 4, and spring 3 and buffer board 4 are all set
Put in drift screwed hole 2-1；The drift covers 2 end surfaces and is provided with the bulge loop hole to match with bulge loop 1-2.
The drift threaded post bear against buffer board 4 after being threadedly coupled with drift screwed hole 2-1 phases；When bulge loop 1-2 one end
When stretching into behind bulge loop hole tight against the inner bottom surface that press against bulge loop hole, buffer board 4 can make spring 3 do some elastic deformations, so set
The purpose put is：Spring 3 and buffer board 4 both axially will not produce larger bounce along drift screwed hole 2-1 to drift body 1,
Meanwhile in drift 1 punching of body, spring 3 and buffer board 4 can play certain cushioning effect, effectively extend drift body 1
With the service life of drift set 2.
Further, the bottom surface in the bulge loop hole is provided with buffering ring flat-plate 5, bulge loop 1-2 stretch into one end behind bulge loop hole tight against
It press against buffering ring flat-plate 5；In drift 1 punching of body, buffering ring flat-plate 5 can play certain cushioning effect, effectively extend drift
The service life of body 1 and drift set 2.
Further, the buffering ring flat-plate 5 is made using elastomeric material.
Further, the cross section of the boss 1-1 is in annular.
When using the utility model, after being mutually threadedly coupled with drift screwed hole by rotary punch threaded post, work as bulge loop
One end is just stopped the rotation drift threaded post when stretching into behind bulge loop hole tight against the inner bottom surface that press against bulge loop hole, and now buffer board just compresses
Spring, make spring that elastic deformation occur, spring and buffer board can play certain cushioning effect, effectively extend drift body and
The service life of drift set；In addition, drift set is fixed in mold, drift body is used with drift set and is threadedly coupled, so as to
Quick-replaceable drift body is realized, removable drift is become, is greatly user-friendly.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
