Abstract

The utility model relates to a disclike workpiece stretching mould, in particular to a disclike workpiece stretching mould for processing a cover plate of an air cylinder on a right angle valve. The disclike workpiece stretching mould comprises a mould plate, a pressure plate and a punch. The mould plate is provided with a recess, and a flat pit for placing a panel is formed in the upper surface of the mould plate in a position above the recess. The pressure plate is provided with a circular hole which corresponds to the flat pit and the recess in the mould plate in position. The punch is divided into an upper section and a lower section. The upper section is cylindrical, and the diameter of the upper section is equal to that of the circular hole in the pressure plate. The lower section is a trapezoidal cylinder, and the shape of the lower section corresponds to that of the recess in the mould plate. The diameter of the lower end of the lower section of the punch plus two times of thickness of the panel is equal to the diameter of the bottom of the recess in the mould plate. The diameter of the upper end of the lower section of the punch plus two times of thickness of the panel is equal to the diameter of the top of the recess in the mould plate. The disclike workpiece stretching mould is less in energy consumption and low in production cost. The disclike workpiece produced by the disclike workpiece stretching mould is good in quality and low in rejection ratio.

Description

The plate-like workpiece drawing die
Technical field
The utility model 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.
The utility model content
The problem that the utility model 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 utility model is taked following technical scheme:
The plate-like workpiece drawing die characteristics of the utility model are to comprise template, pressing plate and drift, and pit is arranged on the template, and the pit upper end is tubaeform.The template upper surface is useful on the flat hole of placing sheet material above pit, the degree of depth in flat hole equates with the thickness of sheet material.On the said pressing plate circular hole is arranged, the position of flat hole and 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 pit is corresponding on its shape and the template, the diameter and the epimere equal diameters of hypomere upper end.The diameter of pit bottom on sheet metal thickness=template of diameter+two of drift hypomere lower end times, the diameter at 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 pit on the template and drift are all concentric with flat hole.
Take such scheme, have the following advantages:
Can find out by such scheme, only need the plate-like workpiece drawing die and the stamping machine of the utility model 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.The plate-like workpiece that is stamped to form owing to the plate-like workpiece drawing die that adopts the utility model again, 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.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 the plate-like workpiece drawing die structural representation of the utility model;
Fig. 2 is the plate-like workpiece drawing die decomposing schematic representation of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, the plate-like workpiece drawing die of the utility model comprises template 6, pressing plate 2 and drift, and pit 5 is arranged on the template 6, and pit 5 upper ends are tubaeform.Template 6 upper surfaces are useful on the flat hole 1 of placing sheet material above pit 5, the degree of depth in flat hole 1 equates with the thickness of sheet material.On the said pressing plate 2 circular hole is arranged, the position of flat hole 1 and 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 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 pit 5 in the present embodiment.The diameter of pit 5 bottoms on sheet metal thickness=template of diameter+two of drift hypomere 4 lower ends times, the diameter at 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 pit on the template 5 and drift are all concentric with 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 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 pit 5 on the circular hole and template successively fast, metallic plate is struck out plate-like workpiece.
