Abstract

The utility model provides a double-layer stainless steel draw die. The die comprises a die set consisting of a lower die base, a guide post and guide bushing assembly and an upper die base. A die insert is fixed on the upper die base, a punch insert is fixed on the lower die base, a clamping plate is also arranged on the lower die base, and a blank holder insert is fixed on the clamping plate around the inner cavity of the punch insert. Draw beads are arranged near the cavity of the die insert, and draw beads are correspondingly arranged on the upper surface of the blank holder insert. The utility model has the advantages that the die insert is embedded in an upper plate, which is convenient for processing and modifying dies; the fluidity of materials is changed by the draw beads so as to prevent parts from crumpling, folding and cracking in the drawing process; the blank holder insert is fixed on the clamping plate, which is convenient for processing and modifying dies; the punch insert is embedded in a lower plate, which facilitates die processing and modification. Through designing reasonable die structure, the utility model realizes the draw of a casing of double layers of overlapped stainless steel.

Description

The double-layer stainless steel drawing die
Technical field
The utility model relates to a kind of drawing die, especially the double-layer stainless steel drawing die.
Background technology
439L, 436L are ferritic stainless steels, good corrosion resistance, and purposes is wide, but intensity, hardness height are usually used in making suppressor case.A kind of suppressor case that has occurred is made up of upper half-shell and housing lower half, and housing lower half is made of the double-layer stainless steel stack.The deep-drawing mould that does not also occur double-layer stainless steel in the present auto vendor at home and abroad.
Summary of the invention
For drawing of the housing of realizing double-layer stainless steel stack, the utility model proposes a kind of drawing die that is fit to draw the housing of double-layer stainless steel stack.
The technical solution of the utility model is: the double-layer stainless steel drawing die, comprise the mould bases that constitutes by die shoe, guide pillar guide pin bushing assembly, upper bolster, it is characterized in that: die plate insert is fixed on the upper bolster, punch insert is fixed on the die shoe, on die shoe, also be provided with holding pad, be fixed with blank holder on the inner chamber of holding pad around punch insert and insert; Die cavity next door at die plate insert is provided with bead, and correspondence is provided with bead on the upper surface that blank holder is inserted.
Beneficial effect: die plate insert embeds the cope match-plate pattern the inside, is convenient to like this process and repair a die; Bead be the flowability that changes material, prevent part wrinkling in drawing process, repeatedly material and cracking; Insert wedge pressure flitch the inside of blank holder is convenient to processing like this and is repaired a die; Punch insert embeds above the lower bolster, is convenient to like this process and repair a die.The utility model is by being provided with rational mould structure, realized the drawing of housing of double-layer stainless steel stack.
