Abstract
The utility model relates to a kind of Novel numerical control punch breakdown mould, comprise die shank, punch holder and drift, punch holder and die shank are that bayonet socket is connected, one end that die shank is connected with punch holder arranges dop, dop side arranges three draw-in grooves isometric with dop length, three draw-in grooves are positioned at one circumferentially, and by described circumference trisection; One end that punch holder is connected with die shank arranges cutting ferrule, and cutting ferrule comprises three projections matched with the draw-in groove of dop; The other end of punch holder connects drift.The breakdown plunger chip die structure that the utility model provides is simple, is beneficial to batch production, only changes drift and punch holder, avoid waste of material when drift weares and teares.
Description
Technical field
the utility model relates to numerical control press technical field, is specifically related to a kind of punching machine mold.
Background technology
Small size mold and punching head in existing numerical control press is mostly holistic drift, and after the cutting edge wearing and tearing of drift bottom, whole Zhi Chongtou scraps and can not use, and needs the drift more renewed.Because the material of drift is high-speed tool steel, manufacturing cost is high, thus causes very large waste.Minority uses knockdown drift, and because structure is more complicated, the accuracy of manufacture requires high, and cost increases a lot, is unfavorable for batch production, affects the popularization of Combined punch pin.
Utility model content
the technical problems to be solved in the utility model is to provide a kind of punch press breakdown mould, avoids causing whole set of die to be scrapped because of drift wearing and tearing, and structure is simple simultaneously, is beneficial to batch production.
For solving the problems of the technologies described above, the utility model relates to a kind of Novel numerical control punch breakdown mould, comprise die shank, punch holder and drift, described punch holder and die shank are that bayonet socket is connected, one end that described die shank is connected with punch holder arranges dop, described dop side arranges three draw-in grooves isometric with dop length, and described three draw-in grooves are positioned at one circumferentially, and by described circumference trisection; One end that described punch holder is connected with die shank arranges cutting ferrule, and described cutting ferrule comprises three projections matched with the draw-in groove of dop; The other end of described punch holder connects drift.
Preferably, described drift and punch holder are formed in one structure.
Preferably, the contact surface of described dop and cutting ferrule comprises two gradients.
Preferably, between described dop and cutting ferrule, alignment pin is set.
When connecting die shank and punch holder, the projection of cutting ferrule aimed at the draw-in groove of dop and insert mutually, cutting ferrule is rotated 60 ° after having mated and can complete fixing by the two, to firm further, can insert alignment pin, prevent from rotating between cutting ferrule and dop coming off.
The breakdown punching machine mold structure that the utility model provides is simple, is beneficial to batch production, only changes drift and punch holder, avoid waste of material when drift weares and teares.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
See Fig. 1,2, the utility model relates to a kind of Novel numerical control punch breakdown mould, comprises die shank 1, punch holder 2 and drift 3, punch holder 2 with die shank 1 for bayonet socket is connected.One end that die shank 1 is connected with punch holder 2 arranges dop 11, and dop 11 side arranges three draw-in groove 111, three draw-in grooves 111 isometric with dop length and is positioned at one circumferentially, and by described circumference trisection.One end that punch holder 2 is connected with die shank 1 arranges cutting ferrule 21, and cutting ferrule 21 comprises three projections 211 matched with the draw-in groove 111 of dop 11; The other end of punch holder 2 connects drift 3.Drift 3 and punch holder 2 are formed in one structure.Alignment pin 4 is set between dop 11 and cutting ferrule 21.
Dop 11 comprises two gradients with the contact surface of cutting ferrule 21, can play certain cushioning effect.
When connecting die shank 1 with punch holder 2, the projection 211 of cutting ferrule 21 is aimed at the draw-in groove 111 of dop 11 and inserts mutually, cutting ferrule 21 is rotated 60 ° along A-A direction after having mated and can complete fixing by the two, to firm further, alignment pin 4 can be inserted, prevent from rotating between cutting ferrule 21 and dop 11 coming off.
Be more than better embodiment of the present utility model, but protection domain of the present utility model is not limited thereto.Any those of ordinary skill in the art are in the technical scope disclosed by the utility model, and the conversion expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore the protection domain that protection domain of the present utility model should limit with claim is as the criterion.
