Description
Technical field
A kind of pipe fitting punch die is the utility model is related to, applied to guardrail punching techniques field.
Background technology
Guardrail is mainly used in the occasions such as house, highway, shopping centre, public place the guarantor to personal safety and installations and facilities
Shield and protection, it is necessary to be punched out to the transverse tube and standpipe of guardrail, in punching, in the market in guardrail process
Majority uses the steel alloy core rod of monoblock type, is provided with hole in core rod, is punched out operation, steel alloy core rod cost is larger and in length
In phase batch production, core rod can be damaged necessarily, it is necessary to change in time, must when otherwise can influence the quality of punching, and change
Palpus monoblock is changed, and mould consumption is larger, have impact on the economic benefit of enterprise to a certain extent.
Utility model content
To solve the defects of prior art, the utility model discloses a kind of pipe fitting punch die, and structure is novel, greatly
Entreprise cost is saved greatly.
The utility model discloses a kind of pipe fitting punch die, including：Core rod set, core rod, pin, rectangular channel, groove, punching
Kong Yi, punching two, projection, the core rod put centre of surface and are provided with rectangular channel, set respectively in the left and right sidewall of the rectangular channel
A groove is equipped with, the projection is two left and right ends Middle faces for being separately positioned on core rod, and the projection is one with core rod
Forming structure, the core rod are fastened in the rectangular channel that core rod is put, and projection coordinates with groove gap, the core rod set
One pin is set respectively on front-rear side walls, and the pin covers core rod to link together with core rod, below the rectangular channel
Core rod, which is put, is provided with punching one, and the middle part that the core rod corresponds to punching one is provided with punching two.
The punching one and punching two are coaxial aperture, and aperture shape size is identical.
The core rod is made up of alloy steel material.
Using the technical program, there is following excellent beneficial effect：
1st, structure is novel；
2nd, entreprise cost has been saved, has improved the economic benefit of enterprise.
Brief description of the drawings
Fig. 1 is a kind of overlooking the structure diagram of pipe fitting punch die of the utility model；
Fig. 2 is the structural representation that core rod covers in the utility model；
Fig. 3 is the structural representation of core rod in the utility model.
Wherein：1- core rod sets；2- core rods；3- pins；4- rectangular channels；5- grooves；6- punchings one；7- punchings two；8- projections.
Embodiment
As Figure 1-3, the utility model discloses a kind of pipe fitting punch die, including：Core rod set 1, core rod 2, pin
3rd, rectangular channel 4, groove 5, punching 1, punching 27, projection 8, the core rod cover 1 upper surface center and are provided with rectangular channel 4, the square
A groove 5 is respectively arranged with the left and right sidewall of shape groove 4, the projection 8 is two left and right ends for being separately positioned on core rod 2
Middle face, the projection 8 and core rod 2 are formed in one structure, and the core rod 2 is fastened in the rectangular channel 4 on core rod set 1, and
Projection 8 and the gap of groove 5 coordinate, and set a pin 3 on the front-rear side walls of the core rod set 1 respectively, and the pin 3 is by core rod
Set 1 links together with core rod 2, is provided with punching 1 on the core rod set 1 of the lower section of rectangular channel 4, the core rod corresponds to punching
One 6 middle part is provided with punching 27.
The punching 1 and punching 27 are coaxial aperture, and aperture shape size is identical.
The core rod 2 is made up of alloy steel material.
The utility model is implemented：During punching, core rod 2 is fastened on core rod set 1, and fixed by pin 3,
Inside pipe fitting is then placed in, when perforating press pushes, after head passes through pipe wall, passes, adds from punching 27, punching 1 successively
Work goes out required hole, using the technical program, need to only regularly replace core rod 2, during replacing, only pin 3 need to be removed, by core rod 2
Taken out from rectangular channel 4, due to only having core rod 2 made for steel alloy, holistic cost greatlys save, and improves the warp of enterprise
Ji benefit.
Finally it should be noted that：Above example only not limits the utility model and retouched to illustrate the utility model
The technical scheme stated；Therefore, although this specification the utility model is had been carried out with reference to above-mentioned each embodiment it is detailed
Illustrate, still, it will be understood by those within the art that, still the utility model can be modified or equally replaced
Change；And all do not depart from technical scheme and its improvement of spirit and scope of the present utility model, it all should cover new in this practicality
In the right of type.
