Abstract
The utility model relates to a kind of dual stage stretch die, comprise upper die and lower die, described patrix comprises upper plate, upper plate arranges punch, described counterdie comprises lower plate, and lower plate arranges die, and described punch is double polarizing keys structure, described die is concave-concave mode structure, the edge rounding of described punch and die.After adopting such structure, dual stage stretch die design double polarizing keys stretching structure of the present utility model, ejecting structure in the middle of adopting, and stretching fillet is optimized, ensure that in workpiece drawing process, arc transition is level and smooth.
Description
Technical field
The utility model relates to a kind of auto parts and manufactures field, specifically a kind of mould of central portion.
Background technology
A lot of component shape such as vehicle manhole cover, chimney lid is circular at present, requires that workpiece must round and smooth, sealing simultaneously.Mainly containing two kinds of mode one is in the mill Welding Structures, and one is drawing and forming structure.The first Welding Structure form, more difficult control on workpiece workmanship, and efficiency is low, and uniformity is not high.
Utility model content
Problem to be solved in the utility model is to provide a kind of mould processing two round platform workpiece, solves the shortcoming that original mould is sufficiently oily, sealing is not good, uniformity is not high.
For solving the problems of the technologies described above, dual stage stretch die of the present utility model, comprise upper die and lower die, described patrix comprises upper plate, and upper plate arranges punch, and described counterdie comprises lower plate, lower plate arranges die, described punch is double polarizing keys structure, and described die is concave-concave mode structure, the edge rounding of described punch and die.
After adopting such structure, dual stage stretch die design double polarizing keys stretching structure of the present utility model, ejecting structure in the middle of adopting, and stretching fillet is optimized, ensure that in workpiece drawing process, arc transition is level and smooth.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the sectional view of the utility model patrix.
Fig. 2 is the sectional view of the utility model counterdie.
Detailed description of the invention
As depicted in figs. 1 and 2, dual stage stretch die of the present utility model, comprise upper die and lower die, patrix comprises upper plate 1, upper plate 1 is arranged punch 2, and described counterdie comprises lower plate 3, lower plate 3 is arranged die 4, punch 2 is double polarizing keys structure, and die 4 is concave-concave mode structure, the edge rounding of punch 2 and die 4.
