Utility model content
The deficiency of prior art existence in view of the above, the purpose of this utility model is to provide a kind of aluminum-base silicon carbide U-shaped extrusion die, to realize preventing inductile alloy from producing face crack when extruding and reducing the noncontact distortion of metal when flowing into work strip, thus have adjusted metal flow uniformity, ensure that product size precision, improve die life.
The utility model is achieved through the following technical solutions:
The U-shaped extrusion die of a kind of aluminum-base silicon carbide that the utility model provides, comprises die body, and described die body is cylindrical structural, and the centre of described die body is provided with the water conservancy diversion hole of indent; The forming cavity run through is provided with in described water conservancy diversion hole; Described forming cavity is U-shaped nib; The inward flange on top, described water conservancy diversion hole is provided with entrance chamfering; The upper outer edges of described water conservancy diversion hole two ends is ellipse arc; The inside lock place in described water conservancy diversion hole is rounding off.
Further, the shape in described water conservancy diversion hole is identical with forming cavity, is of a size of 0.5 ~ 1.2 times of forming cavity.
Further, described water conservancy diversion hole is provided with straight section and changeover portion along the axial direction of die body, and the bottom of described changeover portion is provided with arc angling.
Further, the two ends place of described water conservancy diversion hole changeover portion is provided with the short stream angle for aluminium bar flowing, and the upper outer edges at described short stream angle is ellipse arc, and it is identical that its shape and water conservancy diversion cheat termination, and inwall is the arc conical surface wide at the top and narrow at the bottom.
Further, the described arc conical surface be tilted under direction be center away from die body.
Further, the radial direction along described die body is evenly provided with at least two fixing holes, and the distance between adjacent described fixing hole is equal.
Further, described fixing hole peritreme place is provided with chamfering.
Advantageous Effects of the present utility model is: the utility model by arranging the mode in water conservancy diversion hole and entrance chamfering on die body, prevent inductile alloy from producing face crack when extruding and reduce the noncontact distortion of metal when flowing into work strip, thus have adjusted the uniformity of metal flow, aluminium bar flow velocity in forming cavity can be made to be consistent, thus make the defects such as aluminum-base silicon carbide composite surface of extruded profiles flawless, scuffing, and ensure that the dimensional accuracy of product, for the industrial volume production of aluminum-base silicon carbide composite extrudate provides prerequisite; Meanwhile, the utility model also add short stream corner structure, thus improves mold integral intensity, extends the mold use life-span.
The advantage of the utility model annex provides in the description of detailed description of the invention part below, and part will become obvious from the following description, or be recognized by practice of the present utility model.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is mould structure stereogram in prior art;
Fig. 2 is the utility model mould structure stereogram;
Fig. 3 is the utility model mould structure front view;
Wherein, 1-die body, 2-water conservancy diversion is cheated, 3-entrance chamfering, 4-straight section, 5-changeover portion, 6-short stream angle, 7-forming cavity, 8-fixing hole.
Detailed description of the invention
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail; Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in Figure 2,3, the U-shaped extrusion die of a kind of aluminum-base silicon carbide that the utility model provides, comprises die body 1, and described die body is cylindrical structural, and the centre of described die body is provided with the water conservancy diversion hole 2 of indent; The forming cavity 7 run through is provided with in described water conservancy diversion hole; Described forming cavity is U-shaped nib; The inward flange on top, described water conservancy diversion hole is provided with entrance chamfering 3; The upper outer edges of described water conservancy diversion hole two ends is ellipse arc; The inside lock place in described water conservancy diversion hole is rounding off.After the utility model increases the water conservancy diversion hole of indent, aluminium section bar extrudes better effects if, wall thickness is more even, because before extrusion, aluminium bar after heating enters mould and can first fill full by whole water conservancy diversion hole die, and then extrudes from forming cavity, is equivalent to add certain extrusion pressure, and the aluminium shape surface extruded is smooth, uniform wall thickness, the section bar making wall thickness thinner also can reach good effect, greatly improves the quality of products.
As the improvement of the present embodiment, the shape in described water conservancy diversion hole is identical with forming cavity, is of a size of 0.5 ~ 1.2 times of forming cavity.
As the improvement of the present embodiment, described water conservancy diversion hole is provided with straight section 4 and changeover portion 5 along the axial direction of die body, and the bottom of described changeover portion is provided with arc angling, utilizes aluminium bar mobility in water conservancy diversion hole.
As the improvement of the present embodiment, the two ends place of described water conservancy diversion hole changeover portion is provided with the short stream angle 6 for aluminium bar flowing, the upper outer edges at described short stream angle is ellipse arc, it is identical that its shape and water conservancy diversion cheat termination, inwall is the arc conical surface wide at the top and narrow at the bottom, and the direction under the described arc conical surface is tilted to is the center away from die body.The utility model aluminium section bar when extruding is squeezed in forming module along taper seat, reduces resistance and flow distance, makes that its extending effect is better, Surface of profile is bright and clean, quality is high, further ensures the uniformity of the two ends place metal flow at U-shaped nib.
In the present embodiment, the radial direction along described die body is evenly provided with at least two fixing holes 8, and the distance between adjacent described fixing hole is equal; Described fixing hole peritreme place is provided with chamfering.
The utility model has the advantage of can simplification of flowsheet, enhance productivity, shorten the production cycle, reduce production cost, there is obvious economic benefit.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
