Abstract
The invention relates to a drawing die for a disc-shaped workpiece, in particular to a drawing die for machining a disc-shaped workpiece of a cylinder cover plate on a right angle valve. The drawing die is characterized by comprising a die plate, a pressing plate and a punch, wherein the die plate is provided with a disc-shaped pit, and a shallow flat bottom pit for containing a plate is arranged above the disc-shaped pit in the upper surface of the die plate. The pressing plate is provided with a circular hole corresponding to the positions of the shallow flat bottom pit and the disc-shaped pit in the die plate. The punch is divided into an upper segment and a lower segment, wherein the upper segment is of a cylinder, the diameter of the upper segment is equal to the diameter of the circular hole, the lower segment is of a trapezoid cylinder, and the shape of the lower segment corresponds to that of the disc-shaped pit in the die plate. The sum of the diameter of the lower end of the lower segment of the punch and the twofold thicknesses of the plate is equal to the diameter of the bottom of the disc-shaped pit in the die plate, and the sum of the diameter of the upper segment of the lower segment of the punch and the twofold thicknesses of the plate is equal to the diameter of the top of the disc-shaped pit in the die plate. The drawing die for the disc-shaped workpiece is low in energy consumption and production cost. The disc-shaped workpiece produced by using the drawing die is good in quality and low in rejection rate.
Description
Technical field
The present invention relates to a kind of plate-like workpiece diel.Specifically, be the plate-like workpiece drawing die that is used for processing right angle valve upper cylinder cover plate.
Background technology
At present at mechanical processing industry; Being used for the method that working plate-like workpieces adopts mainly is casting method, promptly utilizes plate-like counterdie and column patrix, when pouring molten metal into the plate-like counterdie; The column patrix is got in the plate-like counterdie, thereby molten metal is cast into the plate-like workpiece blank.Then, again metal blank is carried out cut, process required plate-like workpiece.Come metal is carried out melting owing to adopt casting method need be equipped with smelting furnace, it is more to consume energy, and production cost is high.Impurity content owing to employing casting method requirement molten metal is low especially again, otherwise the workpiece content that casts out is prone to bubble.Therefore, the plate-like workpiece that adopts casting method to produce is second-rate, and percent defective is higher.
Summary of the invention
The problem that the present invention will solve provides a kind of plate-like workpiece drawing die.This plate-like workpiece drawing die, power consumption is few, and production cost is low.Adopt the plate-like workpiece of this die production, quality is good, and percent defective is low.
For addressing the above problem, the present invention takes following technical scheme:
Plate-like workpiece drawing die characteristics of the present invention are to comprise template, pressing plate and drift, and the plate-like pit is arranged on the template, and plate-like pit upper end is tubaeform.The template upper surface is useful on the shallow flat hole of placing sheet material above the plate-like pit, the degree of depth in shallow flat hole equates with the thickness of sheet material.On the said pressing plate circular hole is arranged, the position of shallow flat hole and plate-like pit is corresponding on this circular hole and the template.Said drift is divided into epimere and hypomere, and epimere is cylindrical, and its diameter equates that with Circularhole diameter on the pressing plate hypomere is trapezoidal cylinder, and the shape of plate-like pit is corresponding on its shape and the template, the diameter and the epimere equal diameters of hypomere upper end.The diameter of plate-like pit bottom on sheet metal thickness=template of diameter+two of drift hypomere lower end times, the diameter at plate-like pit top on sheet metal thickness=template of diameter+two of drift hypomere upper end times.
Wherein, the circular hole on the said pressing plate, the plate-like pit on the template and drift are all concentric with shallow flat hole.
Take such scheme, have the following advantages:
Can find out by such scheme, only need plate-like workpiece drawing die of the present invention and stamping machine are used, can the discoid workpiece of metallic plate punching be compared with the conventional cast method that do not need smelting furnace, power consumption is few, can reduce production costs.Owing to the plate-like workpiece that adopts plate-like workpiece drawing die of the present invention to be stamped to form, the quality of its quality depends on the quality of sheet metal fully, as long as select sheet material such as stainless steel materials preferably for use, just can guarantee the quality of workpiece again.Therefore, compare, can avoid the generation of bubble in the workpiece, guarantee the quality of workpiece, reduce the percent defective of workpiece greatly with background technology.
Description of drawings
Fig. 1 is a plate-like workpiece drawing die structural representation of the present invention;
Fig. 2 is a plate-like workpiece drawing die decomposing schematic representation of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, plate-like workpiece drawing die of the present invention comprises template 6, pressing plate 2 and drift, and plate-like pit 5 is arranged on the template 6, and plate-like pit 5 upper ends are tubaeform.Template 6 upper surfaces are useful on the shallow flat hole 1 of placing sheet material above plate-like pit 5, the degree of depth in shallow flat hole 1 equates with the thickness of sheet material.On the said pressing plate 2 circular hole is arranged, the position of shallow flat hole 1 and plate-like pit 5 is corresponding on this circular hole and the template.Said drift is divided into epimere 3 and hypomere 4, and epimere 3 is cylindrical, and its diameter equates that with Circularhole diameter on the pressing plate 2 hypomere 4 is trapezoidal cylinder, and the shape of plate-like pit 5 is corresponding on its shape and the template, the diameter of hypomere 4 upper ends and epimere 3 equal diameters.The length of drift hypomere 4 adds the degree of depth that sheet material thickness equals plate-like pit 5 in the present embodiment.The diameter of plate-like pit 5 bottoms on sheet metal thickness=template of diameter+two of drift hypomere 4 lower ends times, the diameter at plate-like pit 5 tops on sheet metal thickness=template of diameter+two of drift hypomere 4 upper ends times.Circular hole on the said pressing plate 2, the plate-like pit 5 on the template and drift are all concentric with shallow flat hole 1.
During work, with anchor clamps template 6 is fixed on the stamping machine base earlier, again the metallic plate that is stamped is put into the shallow flat hole 1 on the template; Then; Utilize anchor clamps that pressing plate 2 is pressed on template 6 upper surfaces, metallic plate is clamped in the middle of template 6 and the pressing plate 2, last; Utilize stamping machine that drift is got on the pressing plate 2 in the plate-like pit 5 on the circular hole and template successively fast, metallic plate is struck out plate-like workpiece.
