Abstract
The utility model relates to a cupped workpiece shaping mould with a step, in particular to a shaping mould used for machining a cupped workpiece with the step on a right angle valve. The cupped workpiece shaping mould with the step is characterized by comprising a moldboard and a punch. A round hole is disposed on the moldboard. The round hole is divided into a first upper segment and a first lower segment. The diameter of the first upper segment is bigger than that of the first lower segment, and the first upper segment and the first lower segment are concentric. Consequently, the step is formed at the joint of the first upper segment and the first lower segment. The punch is divided into a second upper segment and a second lower segment. The second upper segment and the second lower segment are all in a cylinder shape. The diameter of the second upper segment is bigger than the diameter of the second lower segment, and the second upper segment and the second lower segment are concentric. Consequently, the step is formed at the joint of the second upper segment and the second lower segment. The diameter of the second upper segment plus duplex thickness of a panel equals the diameter of the first upper segment. The diameter of the second lower segment plus duplex thickness of the panel equals the diameter of the first lower segment. The cupped workpiece shaping mould with the step is little in energy consumption and low in production cost. A cupped workpiece with the step produced by the cupped workpiece shaping mould is good in quality and low in rejection rate.
Description
Technical field
The utility model relates to the diel of a kind of two-part cylindrical workpiece.Specifically, be the shaping mould that is used for processing the cup-shaped work piece that has step of right angle valve.
Background technology
At present at mechanical processing industry; The method that is used for processing the cup-shaped work piece employing that has step mainly is a casting method; The column patrix that promptly utilizes the cup-shaped counterdie have step to be connected with two-part; When molten metal being poured into the cup-shaped counterdie that has step, the column patrix that two-part is connected gets in the cup-shaped counterdie, thereby molten metal is cast into the cup-shaped work piece blank that has step.Then, again metal blank is carried out cut, process the required cup-shaped work piece that has step.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 has step 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 shaping mould that has step.This cup-shaped work piece shaping mould that has step, power consumption is few, and production cost is low.Adopt the cup-shaped work piece that has step of this shaping mould 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 shaping mould characteristics that have step of the utility model are to comprise template and drift, have circular hole, circular hole to be divided into first epimere and first hypomere on the template.The diameter of first epimere is concentric greater than the diameter of first hypomere and the two, thereby forms step in the junction of the two, and the upper end of first epimere and first hypomere is tubaeform.Said drift is divided into second epimere and second hypomere, and second epimere and second hypomere are cylinder.The diameter of second epimere is concentric greater than the diameter of second hypomere and the two, thereby forms step in the junction of the two, and the lower edge of second epimere and second hypomere is circular-arc.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.
Wherein, the length of said second epimere is not less than the length of first epimere.
Take such scheme, have the following advantages:
Can find out by such scheme; Adopt the cup-shaped work piece shaping mould and the stamping machine that have step of the utility model to be used; The metal cup-shaped work piece that can handle through last operation strikes out the cup-shaped work piece that has step, compares with the conventional cast method, does not need smelting furnace; Power consumption is few, can reduce production costs.Owing to adopt the cup-shaped work piece shaping mould that has step of the utility model to strike out workpiece, its quality quality depends on the quality of sheet metal, 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 shaping mould structural representation that has step of the utility model;
Fig. 2 is the cup-shaped work piece shaping mould 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 shaping mould that has step of the utility model comprises template 5 and drift, has circular hole, circular hole to be divided into first epimere 2 and first hypomere 3 on the template.The diameter of first epimere 2 is concentric greater than the diameter of first hypomere 3 and the two, thereby forms step in the junction of the two, and the upper end of first epimere 2 and first hypomere 3 is tubaeform.Said drift is divided into second epimere 1 and second hypomere, 4, the second epimeres 1 and second hypomere 4 and is cylinder.The diameter of second epimere 1 is concentric greater than the diameter of second hypomere 4 and the two, thereby forms step in the junction of the two, and the lower edge of second epimere 1 and second hypomere 4 is circular-arc.The diameter of sheet metal thickness=first epimere 2 of the diameter of second epimere 1+two times, the diameter of sheet metal thickness=first hypomere 3 of the diameter of second hypomere 4+two times.The length of said second epimere 1 is not less than the length of first epimere 2.
During work; With anchor clamps template 5 is fixed on the stamping machine base earlier; To put into first epimere 2 on the template 5 through the cup-shaped work piece of last operation punching press again, the diameter of first epimere 2 should be identical with the external diameter of cup-shaped work piece at this moment, then; Utilize stamping machine that drift is got in first epimere 2 and first hypomere 3 on the template 5 fast, cup-shaped work piece is struck out the cup-shaped work piece that has step.
Claims (2)
1. the cup-shaped work piece shaping mould that has step is characterized in that comprising template (5) and drift, and circular hole is arranged on the template, and circular hole is divided into first epimere (2) and first hypomere (3); The diameter of first epimere (2) is concentric greater than the diameter of first hypomere (3) and the two, thereby forms step in the junction of the two, and the upper end of first epimere (2) and first hypomere (3) is tubaeform; Said drift is divided into second epimere (1) and second hypomere (4), and second epimere (1) and second hypomere (4) are cylinder; The diameter of second epimere (1) is concentric greater than the diameter of second hypomere (4) and the two, thereby forms step in the junction of the two, and the lower edge of second epimere (1) and second hypomere (4) is circular-arc; The diameter of sheet metal thickness=first epimere (2) of diameter+two of second epimere (1) times, the diameter of sheet metal thickness=first hypomere (3) of diameter+two of second hypomere (4) times.
