Abstract
The invention relates to an inclined plane punching cavity die structure, comprising a tabulate die holder and a cylindrical cavity die which is arranged on the die holder and inclined relative to the plain of the die holder, wherein the upper surface of the cavity die is parallel to the plain of the die holder and is provided with a pore cavity; and the inclined plane punching cavity die structure is characterized in that a columnar cavity die base is arranged between the bottom of the cavity die and the die holder, and the base diameter is greater than the cavity die diameter. Because the base thicker than the cavity die is arranged at the bottom of the cavity die in the inclined plane punching cavity die structure, the defect that the inclined cavity die as a cantilever is difficult to bear excessive pressure is overcome, the cavity die is more steady and firm, and the quality of matched stamping with an upper die is guaranteed. A cavity die split with a pore cavity can be arranged at the upper end of the cavity die to facilitate replacement of pore cavities with different shapes and sizes to adapt to the machining requirements of different workpieces, and flexible connection of the cavity die split is also favorable for replacement when the cavity die split is damaged, thus prolonging the overall service life of the cavity die structure and lowering the cost.
Description
Technical field
The present invention relates to the die structure in a kind of punch process mould, relate in particular to a kind of die structure that is used for the workpiece slope punching.
Background technology
In the common punch process, treat that the punched-plate face is the plane, corresponding die also is arranged to tabular or is parallel to the bulk of workbench.For having the inclined-plane, and workpiece that need punching on the inclined-plane, workpiece fixedly be a problem.Especially inclined-plane to be processed is positioned at the less barrel of diameter of work one end, needs this barrel is enclosed within on the die of form fit, and the inclined-plane is parallel to the die plane, process, so die also is typically designed to the less column of diameter.Because being parallel to the horizontal operation table top usually, installs upper bolster again; Die upper end face and workpiece slope to be processed also need cooperate upper bolster to be parallel to the setting of horizontal plane direction; So the column die must be a cantilever with respect to workbench promptly according to the installation that forms an angle of the gradient on said inclined-plane and horizontal plane.Patrix vertically down dashes, and its drift just in time can be to the vertical punch process in said inclined-plane, and the die diameter is less, be again described cantilever, is difficult to bear that patrix applies than pressure greatly, fractures easily.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of simple in structure, easy to assembly; Improve the press capacity that die bears patrix greatly; More solid and reliable assurance punch process and be provided with cavity splits, be suitable for wider, the inclined-plane punching concave die structure that prolongs the total life-span.
For achieving the above object; The technical scheme that the present invention adopts is: inclined-plane punching concave die structure; Comprise tabular die shoe and the cylindricality die of being located on the said die shoe with respect to the inclination of die shoe plane, said die upper surface is parallel to the die shoe plane, and is provided with vestibule; It is characterized in that: be provided with column die base between said die bottom and the die shoe, said base diameter is greater than said die diameter.
In preferred embodiment of the present invention, further comprise 2-5 times that said base maximum gauge is said die diameter.
In preferred embodiment of the present invention, comprise that further said die top is provided with cavity splits, said vestibule is located on the cavity splits.
In preferred embodiment of the present invention, comprise further between said die bottom and the die shoe being provided with cylindric die base that base diameter is 4 times of said die diameter.
In preferred embodiment of the present invention, comprise that further said die is located at die base upper center.
In preferred embodiment of the present invention, comprise that further said die datum axle is axial to being parallel to die.
In preferred embodiment of the present invention, further comprise said cavity splits clamping or be threadedly connected to said die top.
The invention solves the defective that exists in the background technology; Inclined-plane of the present invention punching concave die structure is provided with the base that is coarser than die in the die bottom; Overcome the die that is obliquely installed is difficult to bear excessive pressure as cantilever defective; Make die more firm, firm, guarantee the stamping quality that cooperates with patrix.The cavity splits of perforated cavities can be set in the die upper end; Be convenient for changing the vestibule of difformity size, to adapt to the different workpiece processing request, the replacing the when flexible connection of cavity splits also helps its damage; Prolong the bulk life time of said die structure, reduce cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is the enlarged diagram of part shown in Figure 1;
Among the figure: 1, workpiece cylindrical portions may, 2, die shoe, 3, upper bolster, 4, die, 5, drift, 6, cavity splits, 8, the die base, 10, block.
The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1; Inclined-plane of the present invention punching concave die structure; Comprise tabular die shoe 2 and the cylindrical die of being located on the said die shoe 24 with respect to the inclination of die shoe 2 planes, said die 4 upper surfaces are parallel to die shoe 2 planes, and die 4 upper surfaces are provided with vestibule.Be provided with cylindric die base 8 between said die 4 bottoms and the die shoe 2, the diameter of said base 8 is 4-4.5 times of said die 4 diameters.Die base 8 upper center are fixed in said die 4 bottoms, and are one-body molded with base 8 or through being threaded, die shoe 2 is provided with block 10 and props up die 4 upper ends with respect to die 4 bearing of trends.The axially parallel of said base 8 is axial in die 4.Said die 4 tops are provided with cavity splits 6, and described vestibule is located on the cavity splits 6, said cavity splits 6 clampings or be threadedly connected to said die 4 tops.
During work, the die structure is installed with die shoe 2 levels and is as the criterion.The residing cylindrical portions may 1 in workpiece inclined-plane to be processed is enclosed within the column structure top of said die 4; Cavity splits 6 upper surfaces are close on the inclined-plane; And be parallel to this surface; Drift 5 on the position alignment upper bolster 3 of hole slot to be processed, upper bolster 3 declines drive drift and dash for 5 times, perpendicular to inclined-plane to be processed it are carried out punch process.To the different needs of different workpieces, change corresponding drift 5 and get final product with cavity splits 6, need not to make again, change whole die structure.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm technical scope according to the claim scope.
