Description
Technical field
The utility model relates to wire-drawing frame field, particularly relates to a kind of wire drawing die and assembly thereof.
Background technology
Current wire drawing machine generally only assembles a wire drawing die, by when the diameter of metal wire rod changes greatly before and after wire drawing die, the drawing stress in metal wire rod can be made comparatively large, cause the metal wire rod quality after wire drawing not ideal enough.
Current wire drawing die changes the structure of core rod owing to not being provided with, and makes wire drawing die can only the corresponding metal wire rod producing a kind of size, comparatively wastes material.
Utility model content
An object of the present utility model is to propose a kind of wire drawing die, and its core rod is replaceable.
For reaching this object, the utility model by the following technical solutions:
A kind of wire drawing die, described wire drawing die comprises core rod and die sleeve, described core rod comprises stem stem, 2 to 4 circumferentially uniform fixture blocks are provided with at the wire inlet end of described stem stem, described die sleeve one end is provided with the draw-in groove coordinated with described fixture block, and described die sleeve is hollow cylinder, is provided with the flange that two of described core rod and die sleeve being compressed are opposed outside described die sleeve, described flange one end has flange face, and the other end is provided with the flange towards the center of circle of this end face.
Further, described core rod adopts carbide alloy manufacture, and described die sleeve adopts stainless steel manufacture.
Further, the workspace of described core rod is coated with ceramic coating.
Further, described fixture block is 3.
Another object of the utility model is to propose a kind of wire drawing die assembly, the wire drawing die that this wire drawing die assembly can be made to have multiple core rod size successively decrease along wire-drawing direction, and core rod is replaceable.
A kind of wire drawing die assembly, it comprises multiple above-mentioned wire drawing die, the aperture of described wire drawing die reduces one by one along wire-drawing direction, described wire drawing die assembly also comprises the fixed head for fixing described wire drawing die, described fixed head is provided with hole, fixes described wire drawing die by bolt through the hole of described flange and described fixed head.
The beneficial effects of the utility model have:
A kind of wire drawing die that the utility model proposes, comprises core rod and die sleeve, and split-type structural is convenient to change core rod; Flange is used for preventing core rod from dropping out, and is convenient to install wire drawing die; The utility model also proposes a kind of wire drawing die assembly, adopts multiple aperture to reduce wire drawing die one by one along wire-drawing direction, makes the reduction that the diameter of metal wire rod is progressive, avoids employing wire drawing die and produces the excessive situation of drawing stress.
Accompanying drawing explanation
Fig. 1 is the explosive view of the wire drawing die that the utility model embodiment provides;
Fig. 2 is the structural representation of the wire drawing die assembly that the utility model embodiment provides.
In figure, 1, core rod; 2, die sleeve; 3, stem stem; 4, fixture block; 5, draw-in groove; 6, flange; 7, flange face; 8, flange; 9, fixed head.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, be a kind of explosive view of wire drawing die that the present embodiment proposes.
Wire drawing die comprises core rod 1 and die sleeve 2, core rod 1 comprises stem stem 3, circumferentially uniform 2 to 4 fixture blocks 4 are provided with at the wire inlet end of stem stem 3, in the present embodiment, adopt 3 fixture blocks, die sleeve 2 one end is provided with the draw-in groove 5 coordinated with fixture block 4, die sleeve 2 is hollow cylinder, the flange 6 that two of core rod 1 and die sleeve 2 being compressed are opposed is provided with outside die sleeve 2, flange 6 one end has flange face 7, the other end is provided with the flange 8 towards the center of circle of this end face, core rod 1 adopts carbide alloy manufacture, die sleeve 2 adopts stainless steel manufacture, fixture block 4 coordinates with draw-in groove 5, fixture block 4 and draw-in groove 5 had not only been located in axial location but also in circumference, core rod 1 is made to be placed in die sleeve 2 comparatively stably, flange 8 on flange 6 prevents core rod 1 from dropping out.
The workspace of core rod 1 is coated with ceramic coating, makes core rod more wear-resisting.
As shown in Figure 2, wire drawing die assembly comprises multiple wire drawing die, in the present embodiment, wire drawing die assembly adopts 3 wire drawing dies, the aperture of wire drawing die reduces one by one along wire-drawing direction, wire drawing die is reduced one by one along wire-drawing direction owing to adopting multiple aperture, the reduction that the diameter of metal wire rod is progressive, avoid employing wire drawing die and produce the excessive situation of drawing stress, wire drawing die assembly also comprises the fixed head 9 for fixing wire drawing die, fixed head 9 is provided with hole, fixes wire drawing die by bolt through the hole of flange 6 and fixed head 9.
Obviously, above-described embodiment of the present utility model is only to clearly demonstrate the utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
