Abstract

The utility model discloses a chamfering die which comprises a die carrier, an upper die and a lower die, wherein the upper die and the lower die are mounted on the die carrier; the upper die comprises a male die and a sloping block; the lower die comprises a lower die holder and a sliding block; the male die and the sliding block are provided with knife edge structures matched with a chamfering part of a product; and the sliding block moves slantways in a matched guiding rail of the lower die holder under the push action of the sloping block to achieve the chamfering operation of cutting the bevel edge of a product end, and the male die is continuously pressed down to complete the operation of cutting an adjacent edge. The chamfering die solves the technical problem that the appearance quality of the product is affected due to non-uniform chamfering which is likely to be caused by adopting a mechanical chamfering method. The chamfering die is high in processing efficiency, low in labor intensity and suitable for large batch production.

Description

Chamfer mould
Technical field
The utility model discloses a kind of chamfer mould, divides by International Patent Classification (IPC) (IPC) to belong to the technology of die manufacturing field, and the mould that tool not relates to a kind of product periphery chamfering improves structure.
Background technology
Along with the development of social production technical merit, increasingly high to size, the appearance requirement of product at present, product not only size, assembling will reach requirement, and profile seems also attractive in appearance.The chamfering operation is the burr that produces because of machined on the product parts in order to remove, and also for the ease of the part assembling, generally makes chamfering in the part end; Tradition chamfering mode generally adopts handwork, bad control such as appearance and size, and hurt product surface easily; Cause the bad phenomenon of product scratch, scuffing; If with the processing of CNC computer milling machine, cost is too high, and production efficiency is low; And use fashion of extrusion, and can only a little less angles, run into bigger chamfering, because metal material is mobile poor, the part product of moulding does not reach effect.
China document CN201110347560.0 discloses a kind of punching press chamfering and has used mould; Comprise die shank, upper bolster, upper padding plate, fixed head, pressure head, discharging centring ring, counterdie and die shoe; This mould is to utilize pressure head under the effect of forcing press, to be exerted pressure in the part aperture, makes the shape and size of the main needs of aperture material compression.
China document CN201110170766.0 chamfer mould; Comprise the punch and the die that match; Punch and die have and corresponding chamfering patrix of product chamfered section shape and chamfering counterdie, are particularly useful for the battery terminal part that mold pressing production end has chamfering.
This case inventor creates a chamfer mould device through studying for a long period of time and retrieving lot of documents, so just there is the utility model to propose. 
Summary of the invention
To the deficiency of prior art, the utility model provide a kind of rational in infrastructure, efficient is high, the uniform chamfer mould of chamfering, utilize cooperating of patrix and counterdie to accomplish the operation of parts chamfering, thereby improve the quality of products and production efficiency.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of chamfer mould comprises mould bases and the upper die and lower die that are mounted thereon, wherein:
Patrix, it comprises punch and skewback, punch side wherein is provided with the edge of a knife structure that matches with the product end chamfered section;
Counterdie, it comprises die shoe and chamfering slide block, chamfering slide block wherein has the edge of a knife structure that matches with product end hypotenuse chamfered section;
Described chamfering slide block is the oblique movable product end hypotenuse blank chamfering operation that realizes in the cooperation guide rail of the promotion lower edge of patrix skewback die shoe, and punch continues to press down completion product adjacent edge side cut operation.
Further, having vertical hole slot on the described chamfering slide block is used for punch and runs through and accomplish product end surface side cut operation.
Further, the top of described punch and skewback is individually fixed on the mould bases, and the length of skewback is accomplished hypotenuse blank operation so that skewback is first with the effect of chamfering slide block greater than punch length.
Further, described chamfering slide block edge of a knife structure is made up of the continuous straightway of R2.1 segmental arc and bottom of both sides.
Further, there is die cavity to be used for fixing product in the described die shoe and cooperates punch, skewback to press down matched moulds.
The utility model is the mould that is used for product periphery chamfering; Comprise mould bases, punch, slide block, skewback, utilize the mode of the direct blank of the edge of a knife of slide block to accomplish chamfering, because the edge of a knife is fixed; So good product consistency that processes; The mold notch of the utility model comprises the punch and the edge of a knife above the slide block, and the mould blank is used adjacent two actions in a limit of punch cut again for after cutting a limit with slide block.
The utility model has solved and has added chamfering method with machine and cause chamfering inhomogeneous easily, influences the technical problem of product appearance quality, and the utilization of this mould simultaneously adds chamfering relatively with machine, has improved production efficiency greatly, has practiced thrift production cost; Use to have overcome the uneven phenomenon of chamfering in this Mould Machining process, working (machining) efficiency is high, labour intensity is low, is suitable for large batch of production.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 1 to Fig. 4, a kind of chamfer mould comprises mould bases 4 and the upper die and lower die that are mounted thereon, wherein:
Patrix, it comprises punch 3 and skewback 2, punch side wherein is provided with the edge of a knife structure 30 that matches with the product end chamfered section;
Counterdie, it comprises die shoe and chamfering slide block 1, chamfering slide block 1 wherein has the edge of a knife structure 10 that matches with product end hypotenuse chamfered section;
Described chamfering slide block 1 is the oblique movable product end hypotenuse blank chamfering operation that realizes in the cooperation guide rail of the promotion lower edge of patrix skewback 2 die shoe, and punch continues to press down completion product adjacent edge side cut operation.
Having vertical hole slot on the chamfering slide block 1 of the utility model is used for punch and is applied in its descending completion product end surface side cut operation.Chamfering slide block 1 edge of a knife structure is made up of the continuous straightway of R2.1mm segmental arc and bottom of both sides.The top of punch 3 and skewback 2 is individually fixed on the mould bases 4 of upside, and the length of skewback is accomplished hypotenuse blank operation so that skewback is first with the effect of chamfering slide block greater than punch length.Have die cavity to be used for fixing product in the described die shoe and cooperate punch, skewback to press down matched moulds, die shoe is fixed in the mould bases 4 of downside.
