Abstract

The utility model relates to a drawing die for a trumpet-shaped cup-shaped workpiece, in particular to a drawing die for machining the trumpet-shaped cup-shaped workpiece of a connector on a right angle valve. The drawing die is characterized by comprising a die plate, a pressing plate and a punch; the die plate and the pressing plate are both provided with circular holes, and the circular holes of the die plate and the pressing plate correspond to each other; the circular hole on the die plate comprises an upper section and a lower section, the upper section has a shape of a trumpet with a large upper part and a small lower part, and the lower section is cylindrical; the diameter of the upper section is equal to that of the lower section; a flat bottom pit into which a plate is placed is formed on the upper surface of the die plate and above the circular hole; the depth of the flat bottom pit is equal to the thickness of the plate; the punch is cylindrical, and the diameter of the punch is equal to that of the circular hole of the pressing plate; and the diameter of the lower section of the circular hole on the die plate is the sum of the diameter of the punch and the double thickness of the plate. The drawing die for the trumpet-shaped cup-shaped workpiece is low in energy consumption and production cost. The trumpet-shaped cup-shaped workpiece produced by using the drawing die is high in quality and low in rejection rate.

Description

Tubaeform cup-shaped workpiece drawing die
Technical field
The utility model relates to a kind of cylindrical work pieces diel.Specifically, be the drawing die that is used for processing the tubaeform cup-shaped workpiece of connector on the right angle valve.
Background technology
At present at mechanical processing industry; Being used for processing the method that tubaeform cup-shaped workpiece adopts mainly is casting method; Promptly utilize tubaeform cup-shaped counterdie and column patrix; When pouring molten metal into counterdie, patrix is got in the counterdie, thereby molten metal is cast into tubaeform cup-shaped workpiece blank.Then, again metal blank is carried out cut, process required tubaeform cup-shaped 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 tubaeform cup-shaped workpiece quality that adopts casting method to produce is relatively poor, and percent defective is higher.
The utility model content
The problem that the utility model will solve provides a kind of tubaeform cup-shaped workpiece drawing die.This drawing die, power consumption is few, and production cost is low.Adopt the tubaeform cup-shaped 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 tubaeform cup-shaped workpiece drawing die characteristics of the utility model are to comprise template, pressing plate and drift, all have circular hole and the circular hole on the two corresponding on template and the pressing plate.Circular hole on the template is divided into epimere and hypomere, and epimere is up big and down small tubaeform, and hypomere is cylindrical, the diameter of epimere lower end and the equal diameters of hypomere.The upper surface of template is useful on the flat hole of placing sheet material above circular hole, the degree of depth in flat hole equates with the thickness of sheet material.Said drift is cylindrical, and its diameter equates with Circularhole diameter on the pressing plate, the diameter of circular hole hypomere on sheet metal thickness=template of the diameter of drift+two times.
Wherein, the circular hole on the said pressing plate, the circular hole 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 tubaeform cup-shaped workpiece drawing die and the stamping machine of the utility model are used, can be with the cup-shaped work piece of metallic plate punching flue; Compare with the conventional cast method; Do not need smelting furnace, power consumption is few, can reduce production costs.The tubaeform cup-shaped workpiece that is stamped to form owing to the tubaeform cup-shaped 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 tubaeform cup-shaped workpiece drawing die structural representation of the utility model;
Fig. 2 is the tubaeform cup-shaped workpiece drawing die decomposing schematic representation of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, the tubaeform cup-shaped workpiece drawing die of the utility model comprises template 6, pressing plate 3 and drift 2, all has circular hole and the circular hole on the two corresponding on template 6 and the pressing plate 3; Circular hole on the template 6 is divided into epimere 4 and hypomere 5, and epimere 4 is up big and down small tubaeform, and hypomere 5 is cylindrical, the diameter of epimere 4 lower ends and the equal diameters of hypomere 5; The upper surface of template 6 is useful on the flat hole 1 of placing sheet material above circular hole, the degree of depth in flat hole 1 equates with the thickness of sheet material; Said drift 2 is cylindrical, and its diameter equates with Circularhole diameter on the pressing plate 3, the diameter of circular hole hypomere 5 on sheet metal thickness=template of the diameter of drift 2+two times.Circular hole on the said pressing plate 3, the circular hole on the template 6 and drift 3 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 3 is pressed on template 6 upper surfaces, metallic plate is clamped in the middle of template 6 and the pressing plate 3, last; Utilize stamping machine that drift 2 is got in the circular hole and the circular hole on the template 6 on the pressing plate 3 successively fast, metallic plate is struck out tubaeform cup-shaped workpiece.
