Abstract
The utility model relates to a redrawing die for cup-shaped workpieces, in particular to a die for redrawing punched cup-shaped workpieces of cylinders on right angle valves. The redrawing die is characterized by comprising a die plate and a punch, wherein a round hole is formed in the die plate; the upper end of the round hole is trumpet-shaped; the punch is cylindrical; the diameter of the round hole in the die plate is equal to the sum of the diameter of the punch and the duple thickness of a plate; and the round hole in the die plate and the punch are concentric. The redrawing die for the cup-shaped workpieces is low in energy consumption and production cost. The cup-shaped workpieces produced by the die are good in quality and low in defective rate.
Description
Technical field
The utility model relates to a kind of cylindrical workpiece diel.Specifically, be to be used for the cup-shaped work piece of the right angle valve upper cylinder that has been stamped to form is carried out the mould of succeeding stretch.
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.
The utility model content
The problem that the utility model will solve provides a kind of cup-shaped work piece succeeding stretch mould.This cup-shaped work piece succeeding stretch mould, power consumption is few, and production cost is low.Adopt the cup-shaped work piece 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 cup-shaped work piece succeeding stretch die feature of the utility model is to comprise template and drift, and circular hole is arranged on the template, and the circular hole upper end is tubaeform.Said drift is cylindric, the Circularhole diameter on sheet metal thickness=template of its diameter+two times.Circular hole and drift on the said template are concentric.
Take such scheme, have the following advantages:
Can find out by such scheme, only need the cup-shaped work piece succeeding stretch mould and the stamping machine of the utility model are used, can carry out succeeding stretch the cup-shaped work piece that has been stamped to form; Compare with the conventional cast method; Do not need smelting furnace, power consumption is few, can reduce production costs.Owing to adopt template, drift and stamping machine that the cup-shaped work piece that has been stamped to form is carried out succeeding stretch, the quality quality of original metal sheet material has determined the quality of workpiece, 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 the cup-shaped work piece succeeding stretch mould structure sketch map of the utility model;
Fig. 2 is the cup-shaped work piece succeeding stretch mould decomposing schematic representation of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, the cup-shaped work piece succeeding stretch mould of the utility model comprises template 2 and drift 1, on the template 2 circular hole is arranged, and the circular hole upper end is tubaeform.Said drift 1 is cylindric, the Circularhole diameter on sheet metal thickness=template 2 of its diameter+two times.Circular hole and drift 1 on the said template 2 are concentric.
During work; With anchor clamps template 2 is fixed on the stamping machine base earlier, the cup-shaped work piece that will be stamped to form again is put in the circular hole of template 2, then; Utilize stamping machine that drift 1 is got in the circular hole on the template 2 fast, the cup-shaped work piece that has been stamped to form is carried out succeeding stretch.
Claims (1)
1. cup-shaped work piece succeeding stretch mould is characterized in that comprising template (2) and drift (1), and template has circular hole on (2), and the circular hole upper end is tubaeform; Said drift (1) is cylindric, the Circularhole diameter on sheet metal thickness=template (2) of its diameter+two times; Circular hole on the said template (2) and drift (1) are concentric.
