Abstract
The utility model relates to a cup-shaped workpiece flanging mould with steps. The cup-shaped workpiece flanging mould with steps is used for machining workpieces with steps of a right angle valve, and is characterized by comprising a moulding board and a puncher pin, wherein a round hole is arranged in the moulding board, the upper end of the round hole is trumpet-shaped, the puncher pin is divided into an upper section, a middle section and a lower section, the upper section, the middle section and the lower section are all cylindrical and concentric, the diameter of the upper section is larger that of the middle section, the diameter of the middle section is larger than that of the lower section, and the diameter of the round hole is equal to the total value of the diameter of the upper section and duple thickness of a panel. The cup-shaped workpiece flanging mould with steps is low in energy consumption and low in production cost. The workpieces machined by the cup-shaped workpiece flanging mould with steps is good in quality and low in waste product rate.
Description
Technical field
The utility model relates to the diel of a kind of two-part cylindrical workpiece.Specifically, be to be used for processing the flanging die that has the cup-shaped work piece of step on the right angle valve.
Background technology
At present at mechanical processing industry; The method that is used for processing the flange cup-shaped work piece employing that has step mainly is a casting method; Promptly utilize counterdie and patrix; When pouring molten metal into counterdie, patrix is got in the counterdie, thereby molten metal is cast into the cup-shaped work piece blank that has step of crimping.Then, again metal blank is carried out cut, process required 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 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 cup-shaped work piece flanging die that has step.This flanging die, power consumption is few, and production cost is low.The workpiece that adopts this flanging die to produce, 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 flanging die characteristics that have step of the utility model are to comprise template and drift, have circular hole on the template, and the circular hole upper end is tubaeform.Said drift is divided into epimere, stage casing and hypomere, and epimere, stage casing and hypomere are cylindrical and concentric.The epimere diameter is greater than the stage casing diameter, and the stage casing diameter is greater than the hypomere diameter, thereby all forms step in the junction of epimere and stage casing, stage casing and hypomere.Circularhole diameter on sheet metal thickness=template of the diameter of said epimere+two times.
Wherein, the upper, middle and lower section of said drift is all concentric with the circular hole on the template.
Take such scheme, have the following advantages:
Can find out by such scheme, only need cup-shaped work piece flanging die that has step and the supporting use of stamping machine, can carry out the punching press crimping the in type cup-shaped work piece that has step with the utility model; Compare with the conventional cast method; Do not need smelting furnace, power consumption is few, can reduce production costs.Because the workpiece quality of punching press crimping directly depends on the quality of sheet metal,, just can guarantee the quality of workpiece again as long as select sheet material such as stainless steel materials preferably for use.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 flanging die structure sketch map that has step of the utility model;
Fig. 2 is the cup-shaped work piece flanging die decomposing schematic representation that has step of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, the cup-shaped work piece flanging die that has step of the utility model comprises template 1 and drift, has circular hole 2 on the template 1, and circular hole 2 upper ends are tubaeform.Said drift is divided into epimere 3, stage casing 4 and hypomere 5; Epimere 3, stage casing 4 and hypomere 5 are cylindrical and concentric; Epimere 3 diameters are greater than stage casing 4 diameters, and stage casing 4 diameters are greater than hypomere 5 diameters, thereby all form step in epimere 3 and stage casing 4, stage casing 4 with the junction of hypomere 5.Circular hole 2 diameters on sheet metal thickness=template of the diameter of said epimere 3+two times.The epimere 3 of said drift, stage casing 4, hypomere 5 are all concentric with the circular hole 2 on the template.
During work; With anchor clamps template 1 is fixed on the stamping machine base earlier; To be enclosed within on the drift through the cup-shaped work piece that has step after the last operation punching press, two sections cups that have the cup-shaped work piece of step this moment should fit like a glove with hypomere 5 with the stage casing 4 of drift, and the radially outside flange diameter of cup-shaped work piece opening part should be greater than epimere 3 diameters of drift again; Then; Utilize stamping machine to make drift drive cup-shaped work piece and get into fast in the circular hole 2 on the template, till the epimere 3 of drift gets into the circular hole 3 on the template in together with the radially flange of cup-shaped work piece fully, thereby at the opening part formation flange vertically of cup-shaped work piece.
Claims (2)
1. the cup-shaped work piece flanging die that has step is characterized in that comprising template (1) and drift, has circular hole (2) on the template (1), and circular hole (2) upper end is tubaeform; Said drift is divided into epimere (3), stage casing (4) and hypomere (5), and epimere (3), stage casing (4) and hypomere (5) are cylindrical and concentric; Epimere (3) diameter is greater than stage casing (4) diameter, and stage casing (4) diameter is greater than hypomere (5) diameter, thereby all forms step in epimere (3) and stage casing (4), stage casing (4) with the junction of hypomere (5); Circular hole (2) diameter on sheet metal thickness=template of diameter+two of said epimere (3) times.
2. the cup-shaped work piece flanging die that has step according to claim 1 is characterized in that epimere (3), stage casing (4), the hypomere (5) of said drift is all concentric with the circular hole (2) on the template.
