Detailed description of the invention
The present invention is for the mould in a kind of brand-new retainer processing technology.This new technology is, first the steel plate making retainer is cut into rectangle billot, and go out the square opening for placing roller in rectangle billot upper punch, then the billot with holes completing punching is wound into circular tube shaped, and abutment joint welds, form circular pipe workpiece with holes, then by the conical surface of this circular pipe workpiece by the retainer of the stretched required conical surface of conical surface drawing die of the present invention.Come that the present invention is described further below in conjunction with providing a concrete conical surface drawing die.
As Fig. 1,2, this mould primarily of base 14, draw rise slide block 12 and taper pushing block 13 to form.Two parts that taper pushing block is divided into coaxial line to set gradually, be respectively the guide part 132 drawing the portion of rising 131 and cylindricality of taper type, wherein the base 14 of mould is truncated cone-shaped, pilot hole 141 is provided with in base 14 center, this pilot hole is the cylindrical hole running through base 14, taper pushing block 13 is arranged in this pilot hole 141, and frustum type draws the portion of rising 131 can to move up and down vertically in pilot hole under the drive of cylindricality guide part 132, draws the slide block 12 that rises can radially slide along the upper surface of base 14.
As Fig. 3, the upper surface of base 14 is provided with some radial grooves 142 uniform around pilot hole 141, in corresponding some chutes 142 drawing the slide block 12 that rises to be connected to slidably respectively on base 14, make to draw the slide block 12 that rises uniform along the circumference of base 14 upper end taper hole.
As Fig. 4, side, slide block 12 upper end of rising is drawn to be provided with protruding extension section 121, the radial inner end face of this extension section 121 is provided with the inner conical surface drawing the conical surface in the portion of rising 131 suitable with the taper type on taper pushing block 13, when taper pushing block 13 axially moves up, draw the conical surface in the portion of rising 131 to the pushing and pressing of inner conical surface of drawing the slide block 12 that rises by taper pushing block 13 taper type, some slide blocks 12 that rises that draws are slided to radial outside simultaneously.The radial outer end face of the extension section 121 of the slide block 12 that rises is drawn to be provided with the male cone (strobilus masculinus) of tapering identical with the conical surface on retainer, when drawing the slide block 12 that rises to slide to radial outside, rib (described rib is the spacer bar on retainer between two adjacent trapezoidal holes) on this male cone (strobilus masculinus) pushing and pressing workpiece, carries out conical surface stretching to workpiece.
Preferred scheme is that uniform the drawing of circumference slide block 12 quantity that rises is corresponding with the rib 21 on workpiece 2, make like this workpiece 2 when stretching stressed evenly.
As Fig. 6, a preferred scheme arranges groove 1211 on the radial outer end face of the extension section 121 drawing the slide block 12 that rises, and the rib width on the width phase of its further groove 1211 and workpiece 2 is adaptive, and the groove bottom of groove 1211 is described male cone (strobilus masculinus).During place work piece 2, embed in groove 1211 by the rib 21 on workpiece 2, the bottom land of male cone (strobilus masculinus) is used for stretching to the conical surface of the rib 21 on workpiece 2, and due to the effect of groove, during stretching, workpiece and mould do not relatively rotate, and make stretching more stable.
For the ease of retainer workpiece add man-hour can automatically at mould Shang Dui center, the present invention arranges inclined-plane 122 on the downside of the extension section 121 drawing the slide block 12 that rises, this inclined-plane is the inclined-plane raised gradually along the radial radiation direction of its placement location, thus, the slide block 12 that rises is drawn to be sleep down hook-shaped along the shape of base axial section.When workpiece is placed on mould, workpiece slides along inclined-plane 122 to mold center, and owing to drawing the slide block 12 that rises uniform along mold center, so under the effect on this inclined-plane, workpiece can automatically rapidly at mould Shang Dui center.
Taper pushing block 13 can be closely against to make to draw the slide block 12 that rises, and can self-return after completing the slip of drawing and rising, the present invention is also provided with return spring 11, spring 11 with draw the connected mode of the slide block 12 that rises can have multiple, such as the slide block 12 that rises that draws adjacent is between two connected with a spring in circumferential direction; Also can connect all drawing with a spring in the form of a ring to rise slide block 12, the present embodiment adopts two ends to be connected to form ring-spring, and this spring housing is located at the circumferentially uniform outboard end drawing the slide block that rises, and be connected one by one, as Fig. 1 with the slide block that rises of drawing on correspondence position.For the ease of being connected with spring, each draws the outboard end of the slide block that rises to be provided with connecting rod 15, and this connecting rod 15 one end is fixed on to draw rises on slide block, its free end makes annulus, with cross-under spring 11, spring 11 can the annulus of connecting rod 15 end relatively slide, and each section of spring 11 can be made like this to stretch evenly.
When above-mentioned drawing die works, the promotion by guide part 132 of drawing the portion of rising 131 of taper pushing block 13 taper type, move up through taper type draw the conical surface in the portion of rising 131 push against draw the inner conical surface of the slide block 12 that rises make its radius vector diameter gradually general orientation move, spring 11 is constantly stretched, now the rib of workpiece bottom is subject to rising the radial drawing of the male cone (strobilus masculinus) on slide block 12 on extension section 121, workpiece 2 is stretched to the required size conical surface, circular pipe workpiece with holes is made to become Taper Pipe workpiece with holes, as Fig. 5, when the downward returning movement of taper pushing block 13, under the screen resilience effect of spring 11, the slide block 12 radius vector diameter that rises is drawn gradually to move in little direction, get back to initial position, complete drawing work process.
