The specific embodiment
Below in conjunction with accompanying drawing the present invention is explained further details.
A kind of particular manufacturing craft that is used for long thin sheet metal part limit volume circle shaping comprises pre-bending and final two molds that are shaped.Referring to Fig. 1 and Fig. 2, the mould that pre-bends mainly is made up of patrix 1, counterdie 1 and location-plate 3.Patrix one 1 tops are oblique convex shape, and crowning 1 equals the finished product workpiece diameter for about quadrant shape and round diameter.The inclined-plane 1 of patrix 1 and crowning 1 are tangent and be 45 approximately with horizontal plane, so both can avoid when bending workpieces, occurring folding line, can avoid being crowning one 7 interferences of bending workpieces crimp and patrix 1 for the third time again; Counterdie 1 is provided with the groove 1 of an about quadrant shape and the external diameter that round diameter equals the finished product workpiece; Location-plate 3 is fixed on the counterdie 1 through screw 4, and the side 10 of location-plate parallels with the side of counterdie one groove 1, so just can guarantee that first three time bending workpieces crimp height is consistent.
Referring to Fig. 3 and Fig. 4, the final molding mould mainly is made up of patrix 25 and counterdie 26.Patrix 25 tops are oblique convex shape, and the cross section of crowning 2 11 is the rectangle of level, and crowning 2 11 is used for the workpiece location of accomplishing final volume circle the 4th time; Inclined-plane 2 13, location is the groove 2 12 near semicircle with the part that crowning 2 11 joins, and inclined-plane 2 13 is 45 approximately with horizontal plane, can avoid workpiece folding line to occur during bending like this.It is rectangular groove 3 14 that counterdie 26 is provided with a cross section, and the width of groove 3 14 equals the transverse width of crowning 2 11, and groove 3 14 degree of depth are greater than the height of crowning 11.Groove 3 14 is used to dodge and limit the descending of patrix 25.Counterdie 26 is provided with the groove 4 15 of a nearly semicircle in addition; The side of its side and groove 3 14 parallels; The equal diameters of the diameter of groove 4 15 and groove 12 2 and equal the external diameter of finished product workpiece, groove four is connected with groove two and the circle of its cross section for not sealing.
Particular manufacturing craft of the present invention can be arranged at the counterdie of the mould that pre-bends 1 and the counterdie 25 of final shaping dies respectively two adjacent sides of one mold.
Use the thin sheet metal part limit of the length volume circle manufacturing process of above-mentioned particular manufacturing craft, may further comprise the steps:
Step 1: the mould that will pre-bend is installed on the brake-press;
Step 2: regulate the distance of location-plate side 10 and groove one 9 sides, the workpiece blank material is positioned on the mould, the limit of blank material withstands on the location-plate side 10;
Step 3: patrix 1 is descending, realizes bending for the first time, and patrix 1 lifts;
Step 4: the workpiece that bending for the first time is good continues to send forward, and patrix 1 is descending, realizes bending for the second time, and patrix 1 lifts;
Step 5: the workpiece that bending for the second time is good continues to send forward, and patrix 1 is descending, realizes bending for the third time, and patrix 1 lifts;
Step 6: unload the mould that pre-bends, final shaping dies is installed on the brake-press;
Step 7: will be against the side of crowning 2 11 through the good workpiece top of step 5 bending, patrix 25 is descending, realizes final volume circle.
