Using method of the present utility model:

Add man-hour, at first liner is contained in movable matrix, use width and the circular arc and the location-plate location of movable matrix, behind the opening pressure machine, descending along with press ram, be fixed in the upper bolster on the slide block, promote the loading and unloading material plate and compress the liner upside, and promote the movable matrix downslide, liner contacts with following stripper thereupon, the liner lower side is compacted, along with slide block is further descending, last lower punch begins stamping-out, because the effect of gag lever post, last lower punch can only enter into the desired position of design, and can not produce lower punch and waste material collision on two.After punching finished, slide block began up, and last lower punch withdraws from movable matrix and liner under the effect of discharging rubber screen resilience.Movable matrix returns original position under the effect of compression spring, take out workpiece, finishes a working cycles thus.

Design of the present utility model and processing request

The discharging rubber preferably adopts polyamine fat, can apply bigger pressure to workpiece like this, can play the effect of shaping.

The size of gag lever post must be calculated accurately, guarantee punch enter die after 2-3mm get final product.

Add movable matrix in man-hour movable wanting flexibly in the rolling guide pillar, and rocking of any direction can not occur.This requirement adds man-hour, ratio error must not be greater than 0.025mm mutually for rolling guide pillar diameter on rolling bushing on the movable matrix and the die shoe and designing requirement, the cylindricity in rolling bushing hole must not be greater than 0.04mm, and the perpendicularity of rolling bushing hole and end face must not be greater than 0.012mm.

During assembling, in the assurance, lower punch is coaxial with the cutting edge of movable matrix, and error is less than 0.02mm.

Movable matrix adopts the Cr12 material, and heat treatment hardness is 58-62HRC.Consider the manufacturability of processing in design, adopted the edge Analysis of Nested Design at the position that retainer is installed, unit with good conditionsi can cancel.

The localization part of movable matrix: the thickness of movable matrix matches with the liner inner surface with circular arc, consider accurate positioning and be convenient to lay workpiece, and the resilience that in preceding working procedure, produces of liner, the size that guarantees this two place of movable matrix is than the inside contraction of liner 0.045-0.058mm.

The discharge part of movable matrix: the relief hole of movable matrix is installed in the side, and designed the inclined-plane by following direction at movable matrix, to guarantee the smooth eliminating of waste material, consider the intensity and the life problems of movable matrix, therefore the size in four directions, the minimum place of relief hole only needs greater than waste material 2-3mm, the degree of depth only need surpass movable matrix cutting edge 2-3mm, and each right angle part all must be with adopting R2 or above circular arc to carry out transition.
