Abstract
A kind of punch die for producing rectangle head screw, including cylindrical punch die ontology, it is provided with punch die pedestal below the punch die ontology, it is provided with centre hole in the punch die pedestal, it is provided with vertical circular through hole in the punch die ontology, the diameter of the centre hole is more than the diameter of the circular through hole, and the circular through hole upper end is provided with oval bowl-shaped groove, and the circular through hole is connected to setting with the middle part of the oval bowl-shaped groove.The utility model greatly reduces the waste material of trimming generation, since head materials become smaller, impact force also becomes smaller, and the service life of mold is also improved, and production cost is reduced for enterprise, highly practical, is suitble to promote by designing oval bowl-shaped groove on punch die.
Description
Technical field
The utility model belongs to mould development technical field, and in particular to a kind of for producing rushing for rectangle head screw
Mould.
Background technology
Currently, doing rectangular forming head（It is about 30mm, wide about 24mm）Screw when, traditional process is all in-molded
, since head is not regular circular, so four corner angle are less clear full, the requirement of client is not achieved, used instead later
Edger, four corner angle are full, but because head is big round, cause the waste material after trimming too many, and edger because
Forced area is big and is easily damaged.
It is therefore desirable to design a kind of to solve the above problems for producing the punch die of rectangle head screw.
Utility model content
To overcome above-mentioned deficiency in the prior art, the utility model aim to be to provide a kind of for producing rectangular forming head
The punch die of screw.
In order to achieve the above objects and other related objects, technical solution provided by the utility model is：One kind is for producing
The punch die of rectangle head screw, including cylindrical punch die ontology, the punch die ontology lower section are provided with punch die pedestal, the punching
It is provided with centre hole in mould pedestal, vertical circular through hole is provided in the punch die ontology, the diameter of the centre hole is more than
The diameter of the circular through hole, the circular through hole upper end are provided with oval bowl-shaped groove, the circular through hole and the oval bowl
The middle part connection setting of shape slot.
Preferably technical solution is：The length of the ellipse bowl-shaped groove opening short axle is more than 20mm and is less than 25mm, institute
The length for stating oval bowl-shaped groove opening long axis is more than the length of the short axle and the diameter less than the punch die ontology.
Preferably technical solution is：The depth of the ellipse bowl-shaped groove is 9 ~ 10mm.
Preferably technical solution is：The punch die ontology is provided with chamfering.
Since above-mentioned technical proposal is used, the utility model this have the advantage that compared with prior art：
The utility model greatly reduces the waste material of trimming generation, due to head by designing oval bowl-shaped groove on punch die
Portion's materials become smaller, and impact force also becomes smaller, and the service life of mold is also improved, and production cost is reduced for enterprise, highly practical,
It is suitble to promote.
Description of the drawings
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
In the figures above, punch die ontology 1, punch die pedestal 2, centre hole 3, circular through hole 4, oval bowl-shaped groove 5.
Specific implementation mode
Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below
Content disclosed by specification understands other advantages and effect of the utility model easily.
Please refer to Fig.1 ~ Fig. 2.It should be clear that structure, ratio, size etc. depicted in this specification institute accompanying drawings, only to
Coordinate the revealed content of specification, so that those skilled in the art understands and reads, is not limited to the utility model
Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size
Adjustment, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model
Revealed technology contents obtain in the range of capable of covering.Meanwhile in this specification it is cited as "upper", "lower", " left side ",
The term on " right side ", " centre " and " one " etc. is merely convenient to being illustrated for narration, rather than enforceable to limit the utility model
Range, relativeness are altered or modified, enforceable when being also considered as the utility model in the case where changing technology contents without essence
Scope.
As shown in Fig. 1 ~ Fig. 2, a kind of punch die for producing rectangle head screw, including cylindrical punch die ontology 1,
1 lower section of punch die ontology is provided with punch die pedestal 2, centre hole 3 is provided in punch die pedestal 2, it is vertical to be provided in punch die ontology 1
Circular through hole 4, the diameter of centre hole 3 are more than the diameter of circular through hole 4, and 4 upper end of circular through hole is provided with oval bowl-shaped groove 5, circle
Shape through-hole 4 is connected to setting with the middle part of oval bowl-shaped groove 5.
Preferred embodiment is：The length of 5 opening short axle of oval bowl-shaped groove is more than 20mm and is less than 25mm, oval bowl
The length of 5 opening long axis of shape slot is more than the length of short axle and the diameter less than punch die ontology 1.Meet production institute again convenient for trimming
It needs, does not waste material.
Preferred embodiment is：The depth of oval bowl-shaped groove 5 is 9 ~ 10mm.This depth meets most length in industry
It is applied widely needed for rectangular head screw production.
Preferred embodiment is：As shown in Figure 1, punch die ontology 1 is provided with chamfering.Equipment is not hindered in deburring.
The utility model greatly reduces the waste material of trimming generation, due to head by designing oval bowl-shaped groove on punch die
Portion's materials become smaller, and impact force also becomes smaller, and the service life of mold is also improved, and production cost is reduced for enterprise, highly practical,
It is suitble to promote.
The above embodiments are only illustrative of the principle and efficacy of the utility model, new not for this practicality is limited
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model
All equivalent modifications completed under refreshing and technological thought or change, should be covered by the claim of the utility model.
