Abstract
The invention relates to a valve seat necking die, in particular to a die for necking a right-angle valve seat. The valve seat necking die is characterized by comprising a die plate and a punch, a circular hole is arranged on the die plate and includes a first upper section, a first middle section and a first lower section, the diameter of the first upper section is smaller than that of the first lower section, and the first middle section is conical. The punch comprises a second upper section, a second middle section and a second lower section, the diameter of the second upper section is smaller than that of the second lower section, and the second middle section is conical. The sum of the diameter of the second upper section and the double of the thickness of a plate is equal to the diameter of the first upper section, the sum of the diameter of the second lower section and the double of the thickness of the plate is equal to the diameter of the first lower section, and the gradient of a conical surface of the first middle section is as same as that of a conical surface of the second middle section. The valve seat necking die is low in energy consumption and production cost, and the valve seat produced by the necking die is high in quality and low in rejection rate.
Description
Technical field
The present invention relates to a kind of cylindrical workpiece diel.Specifically, be to be used for the right angle valve base is carried out the mould of reducing.
Background technology
At present at mechanical processing industry; Being used for processing the method that the reducing valve seat adopts mainly is casting method, promptly utilizes the cup-shaped counterdie and the column patrix of reducing shape, 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 valve seat blank.Then, again metal blank is carried out cut, process required valve seat.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 valve seat content that casts out is prone to bubble.Therefore, the valve seat 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 valve seat reducing mould.This valve seat reducing mould, power consumption is few, and production cost is low.Adopt the reducing valve seat of this die production, quality is good, and percent defective is low.
For addressing the above problem, the present invention takes following technical scheme:
Valve seat reducing die feature of the present invention is to comprise template and drift, has circular hole, circular hole to be divided into first epimere, first stage casing and first hypomere on the template, and the diameter of first epimere is less than the diameter of first hypomere, and the lower end of first hypomere is tubaeform.Said first stage casing is taper, its upper end diameter and the first epimere equal diameters, its lower end diameter and the first hypomere equal diameters.Said drift is divided into second epimere, second stage casing and second hypomere, and second epimere and second hypomere are cylindrical, and the diameter of second epimere is less than the diameter of second hypomere.Second stage casing is taper, the diameter and the second epimere equal diameters, the diameter of lower end, second stage casing and the second hypomere equal diameters of upper end, second stage casing.The diameter of sheet metal thickness=first epimere of the diameter of second epimere+two times, the diameter of sheet metal thickness=first hypomere of the diameter of second hypomere+two times, and first stage casing is identical with the taper surface slope in second stage casing.
Wherein, the second upper, middle and lower section of first upper, middle and lower section of said template circular hole and drift is all concentric.
Take such scheme, have the following advantages:
Can be found out by such scheme, only need valve seat reducing mould of the present invention and stamping machine are used, can in type cup-shaped valve seat be carried out the punching press reducing, compare with the conventional cast method, not need smelting furnace, power consumption is few, can reduce production costs.Owing to the valve seat that adopts valve seat reducing mould of the present invention to be stamped to form, the quality of its quality directly depends on the quality of original metal sheet material, as long as select sheet material such as stainless steel materials preferably for use, just can guarantee the quality of valve seat again.Therefore, compare, can avoid the generation of bubble in the valve seat, guarantee the quality of valve seat, reduce the percent defective of workpiece greatly with background technology.
Description of drawings
Fig. 1 is a valve seat reducing mould structure sketch map of the present invention;
Fig. 2 is a valve seat reducing mould decomposing schematic representation of the present invention.
The specific embodiment
As depicted in figs. 1 and 2; Valve seat reducing mould of the present invention comprises template 1 and drift, on the template 1 circular hole is arranged, and circular hole is divided into first epimere 4, first stage casing 3 and first hypomere 2; The diameter of first epimere 4 is less than the diameter of first hypomere 2, and the lower end of first hypomere 2 is tubaeform.Said first stage casing 3 is taper, its upper end diameter and first epimere, 4 equal diameters, its lower end diameter and first hypomere, 2 equal diameters.Said drift is divided into second epimere 5, second stage casing 6 and second hypomere, 7, the second epimeres 5 and second hypomere 7 and is cylindrical, and the diameter of second epimere 5 is less than the diameter of second hypomere 7.Second stage casing 6 is taper, the diameter of 6 upper ends, second stage casing and second epimere, 5 equal diameters, the diameter of 6 lower ends, second stage casing and second hypomere, 7 equal diameters.The diameter of sheet metal thickness=first epimere 4 of the diameter of second epimere 5+two times, the diameter of sheet metal thickness=first hypomere 2 of the diameter of second hypomere 7+two times, and first stage casing 3 is identical with the taper surface slope in second stage casing 6.First upper, middle and lower section of said template circular hole and the second upper, middle and lower section of drift are all concentric.
During work; Drift is fixed on the stamping machine base earlier, will be placed on the drift through the cup-shaped valve seat that last operation is stamped to form again with anchor clamps, this moment valve seat internal diameter should with second hypomere, 7 equal diameters on the drift; Then; Utilize stamping machine that template 1 is descended fast, drift and valve seat get in the circular hole on the template 1, can carry out reducing in type valve seat.
