(2) piercing punch adopts conventional step fixed form, punch and fixed head fit clearance are 0.06mm, for ensureing that punch has good rigidity, punch Design of length are become 60mm, final choice be precision standard punch, model specification is SPAL13-60-P9.1.
(3) conveniently manufacture, what outline die punch adopted is straight-through structure, material selection Cr12moV, heat treatment hardness 58 ~ 62HRC, adopts linear cutter, and the dimensional tolerance of working portion presses the manufacture of IT6 level.Cross sectional shape due to this punch is long narrow structure, adopts screw to add the fixed form of locating slot.
(4) bending-be separated punch structure to adopt through type, material selection and heat treatment requirements, to fix square work identical with special-shaped punch.As shown in Figure 10, the initial double-faced clearance in pilot pin and correcting hole is designed to 0.04mm for version and fixing means thereof.
(5) other templates also should have higher precision, and punch retainer, stripper material adopt Cr12, and heat treatment hardness is 53 ~ 55HRC.Punch pilot hole, the region of interest coordinated with inner guiding post adopt low-speed WEDM to process, and mismachining tolerance controls within 0.005mm.
the utility model using die stock layout designs:
As shown in Figure 3, appearance and size is 110mm × 48mm to part development size, and lengthwise dimension is comparatively large, adopts single mode can reduce Making mold difficulty, saves manufacturing cost.Also need during stock layout to consider following factor:
(1) accurately, reliably locating to provide to subsequent handling, reducing accumulated error, punching 2 of giving priority in arranging for
Φ9
+ 0.15mm hole, as the location of second and third step and the fabrication hole of correcting.
(2) for simplifying punch and matrix structure, being convenient to Making mold, improving die life, External Shape is gone out in two steps.
(3) for guaranteeing safety that process part processing sends in mould and steadily, carrier should have enough strength and stiffness, devises bilateral carrier.
(4) for reducing accumulated error, improve stamping precision, when ensureing strength of concave mould, station number should be the least possible, only arranged necessary punching, die-cut, forming cutting 3 stations.
Comprehensive above analysis, be improve stock utilization, should arrange compact between each station, adopt the pattern type of single arrangement, bilateral carrier, as shown in figure 11, billot width is 126mm to stock layout, scrap (bridge) 7mm, step pitch 55mm.Operation is: 1. rush 2 Φ 9
+ 0.15mm hole; 2. die-cut profile waste material; 3. bending forming and die-cut both sides carrier.
As shown in figure 11, station 1 is punching 2 Φ 9 to forming process of the present utility model
+ 0.15mm hole (by piercing punch 12 and punching concave die hole 201); Station 2 is die-cut local form (by the die-cut punch 22 of local form and local outline die die hole 202); Station 3 is bending forming and die-cut both sides carrier (by bending-cut-out punch 11 and bending-cut-out die groove 203).
