Abstract
The invention relates to a primary drawing die for a cup-shaped workpiece, in particular to a primary drawing die for machining a cup-shaped workpiece of a valve head of a right angle valve. The primary drawing die is characterized by comprising a die plate, a pressing plate and a punch, wherein the die plate and the pressing plate are respectively provided with a circular hole, the circular hole in the die plate corresponds to the circular hole in the pressing plate, and the upper end of the circular hole in the die plate is bellmouthed. The lower surface of the pressing plate is provided with a shallow flat bottom pit for containing a plate, and the depth of the shallow flat bottom pit is equal to the thickness of the plate. The diameter of the punch is equal to that of the circular hole in the pressing plate, and the sum of the diameter of the punch and the twofold thicknesses of the plate is equal to the diameter of the circular hole in the die plate. The primary drawing die for the cup-shaped workpiece is low in energy consumption and production cost. The cup-shaped workpiece produced by using the primary drawing die is good in quality and low in rejection rate.
Description
Technical field
The present invention relates to a kind of cylindrical workpiece diel.Specifically, be the preliminary drawing die of cup-shaped work piece that is used for processing right angle valve valve head.
Background technology
At present at mechanical processing industry; Being used for processing the method that cup-shaped work piece adopts mainly is casting method, promptly utilizes cup-shaped counterdie and column patrix, when pouring molten metal into the cup-shaped counterdie; The column patrix is got in the cup-shaped counterdie, thereby molten metal is cast into the cup-shaped work piece blank.Then, again metal blank is carried out cut, process required cup-shaped work piece.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 cup-shaped work piece 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 cup-shaped work piece drawing-die tool just.This cup-shaped work piece is the drawing-die tool just, and power consumption is few, and production cost is low.The cup-shaped work piece that adopts this drawing-die tool just to produce, quality is good, and percent defective is low.
For addressing the above problem, the present invention takes following technical scheme:
Cup-shaped work piece of the present invention just drawing-die tool characteristics is to comprise template, pressing plate and drift, all has circular hole and the circular hole on the two corresponding on template and the pressing plate, and the circular hole upper end on the template is tubaeform.Be useful on the shallow flat hole of placing sheet material on the lower surface of pressing plate, the degree of depth in shallow flat hole equates with the thickness of sheet material.Said punch diameter equates with Circularhole diameter on the pressing plate, the Circularhole diameter 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 shallow flat hole.
Take such scheme, have the following advantages:
Can be found out because the first drawing-die tool of the shape workpiece of cup of the present invention comprises template, pressing plate and drift, all have circular hole and the circular hole on the two corresponding on template and the pressing plate by such scheme, the circular hole upper end on the template is tubaeform.Be useful on the shallow flat hole of placing sheet material on the lower surface of pressing plate, the degree of depth in shallow flat hole equates with the thickness of sheet material.Said punch diameter equates with Circularhole diameter on the pressing plate, the Circularhole diameter on sheet metal thickness=template of the diameter of drift+two times.Adopt template, pressing plate, drift and press, can metallic plate punching be become cup-shaped work piece, compare with the conventional cast method, do not need smelting furnace, power consumption is few, can reduce production costs.Owing to adopt template, pressing plate, drift with press metallic plate punching to be become cup-shaped work piece, the quality quality of sheet metal has determined the quality of workpiece, as long as select better sheet material such as stainless steel materials 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 the cup-shaped work piece of the present invention drawing-die structure sketch map of signing an undertaking just;
Fig. 2 is a cup-shaped work piece of the present invention drawing-die tool decomposing schematic representation just.
The specific embodiment
As depicted in figs. 1 and 2, cup-shaped work piece of the present invention just drawing-die tool comprises template 4, pressing plate 2 and drift 1, all is processed with circular hole on template 4 and the pressing plate 2 and the circular hole on the two is corresponding, wherein, is tubaeform on the circular hole on the template 4.Be processed with the shallow flat hole 3 that is used to place sheet material on the lower surface of pressing plate 2, said shallow flat hole 3 is circular, so that place circular sheet material.The degree of depth in said shallow flat hole 3 equates with the thickness of sheet material.Circular hole on the said pressing plate 2, the circular hole on the template 4 and drift 1 are all concentric with shallow flat hole 3.Said drift 1 diameter equates with Circularhole diameter on the pressing plate 2, the Circularhole diameter on sheet metal thickness=template 4 of the diameter of drift 1+two times.
During work, template 4 is fixed on the press base earlier, again the metallic plate that is stamped is put into the shallow flat hole 3 below the pressing plate 2 with anchor clamps; Then; Utilize anchor clamps to make to have to be pressed on template 4 upper surfaces below the pressing plate 2 of metallic plate, metallic plate is clamped in the middle of template 4 and the pressing plate 2, last; Utilize press that drift 1 is got on the pressing plate 2 in the circular hole on the circular hole and template 4 successively fast, metallic plate is struck out cup-shaped work piece.
Claims (2)
1. the first drawing-die tool of cup-shaped work piece is characterized in that comprising template (4), pressing plate (2) and drift (1), all has circular hole and the circular hole on the two corresponding on template (4) and the pressing plate (2), and the circular hole upper end on the template (4) is tubaeform; Be useful on the shallow flat hole (3) of placing sheet material on the lower surface of pressing plate (2), the degree of depth in shallow flat hole (3) equates with the thickness of sheet material; Said drift (1) diameter equates with Circularhole diameter on the pressing plate (2), the Circularhole diameter on sheet metal thickness=template (4) of diameter+two of drift (1) times.
2. cup-shaped work piece according to claim 1 is the drawing-die tool just, it is characterized in that circular hole, the circular hole on the template (4) and the drift (1) on the said pressing plate (2) is all concentric with shallow flat hole (3).
