Abstract
The invention discloses a bottom chip removal punch comprising an upper segment (1), a middle segment (2) and a lower segment (3). The punch is characterized in that a blind hole (5) is formed in the lower segment (3); an inner chamfer (4) is arranged between the blind hole (5) to a blade (7). The bottom chip removal punch has the advantages of convenience for usage, high positioning accuracy, high machining efficiency, low cost and stable and reliable machining quality.
Description
Technical field
The invention belongs to machining equipment technical field, relate in particular to a kind of removal and consider drift to be worth doing as die-cut hexagonal hole in the interior hexagonal bottom outlet of the parts such as high locked bolts remains the end of removing of considering to be worth doing at the end.
Background technology
Some product such as processing criterion of the parts such as high locked bolts requires the die-cut residual end of removing in its inner hexagonal hole to consider to be worth doing, our usual processing method increases by a procedure in the bottom of die-cut inner hexagonal hole in the past, utilize engine lathe (turret lathe), adopt alloy bit to remove end bits by drilling, such a process increases the difficulty of positioning and clamping, higher to the required precision of equipment, simultaneously because adding operation, production cycle is longer, and cost is higher, efficiency is lower, and not easily ensures the quality of products.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and the one that provides is easy to use, positioning precision is high, and working (machining) efficiency is high, cost is low, and crudy is stable, reliably except end bits drift.
Object of the present invention and solve its technical problem underlying and realize by the following technical solutions:
Of the present invention except end bits drift, comprise epimere, stage casing and hypomere successively, wherein: the inside of described hypomere is provided with blind hole; Interior chamfering is provided with between along blind hole to cutting edge.
Above-mentioned except end bits drift, wherein: the angle of described interior chamfering is 55 ° ~ 60 °.
Above-mentioned except end bits drift, wherein: there is knuckle at the shaft shoulder place between described stage casing and hypomere.
The present invention compared with prior art, there is obvious beneficial effect, as can be known from the above technical solutions: described except end bits drift, comprise epimere, stage casing and hypomere successively, the design of its appearance structure is basically identical with former inner hexagonal hole drift, can utilize the frock such as die holder, positioning sleeve, die shank of former die-cut operation, without the need to adjusting blade clearance during use, without the need to changing die cutting die, one-step punching the requirement of removing bits at the bottom of interior hexagonal bottom outlet can be completed; The angle of described interior chamfering is 55 ° ~ 60 °, be conducive to cutting edge to the residual end consider to be worth doing die-cut; There is knuckle at shaft shoulder place between described stage casing and hypomere, is conducive to reducing stress and concentrates, improve the service life except end bits drift.The present invention has easy to use, and positioning precision is high, and working (machining) efficiency is high, cost is low, stable, the reliable advantage of crudy.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark in figure:
1, epimere; 2, stage casing; 3, hypomere; 4, interior chamfering; 5, blind hole; 6, knuckle; 7, cutting edge.
detailed description of the invention:
Below in conjunction with accompanying drawing and preferred embodiment, remove end bits drift detailed description of the invention, structure, feature and effect thereof to what propose according to the present invention, be described in detail as follows.
See Fig. 1, of the present invention except end bits drift, comprise epimere 1, stage casing 2 and hypomere 3 successively, wherein: the inside of described hypomere 3 is provided with blind hole 5; Interior chamfering 4 is had along between blind hole 5 to cutting edge 7.The angle of described interior chamfering 4 is 55 ° ~ 60 °.There is knuckle 6 at shaft shoulder place between described stage casing 2 and hypomere 3.
Time die-cut, to machine the part of interior hexagonal bottom outlet, reload in former die-cut die holder, die-cut for former outer-hexagonal drift is replaced by except end bits drift, and clamp epimere 1, adjustment punching machine stroke, makes punching depth slightly be greater than the interior hexagonal bottom outlet degree of depth, utilizes the cutting edge 7 of hypomere 3 can complete the requirement of bits at the bottom of die-cut removal.Its design can utilize the frock such as die holder, positioning sleeve, die shank of former die-cut operation, without the need to adjusting blade clearance, without the need to changing die cutting die, the requirement of bits at the bottom of hexagonal bottom outlet in one-step punching completes and removes, easy to use, positioning precision is high, efficiency is high, and cost is low, and crudy is stable, reliable.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
Claims (3)
1., except an end bits drift, comprise epimere (1), stage casing (2) and hypomere (3) successively, it is characterized in that: the inside of described hypomere (3) is provided with blind hole (5); Interior chamfering (4) is provided with between along blind hole (5) to cutting edge (7).
2. as claimed in claim 1 except end bits drift, it is characterized in that: the angle of described interior chamfering (4) is 55 ° ~ 60 °.
3. as claimed in claim 1 except end bits drift, it is characterized in that: there is knuckle (6) at the shaft shoulder place between described stage casing (2) and hypomere (3).
