Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, diaphragm spring continuous stamping method of the present invention comprises the following steps:
Step S1: provide one can jet-bedding, punching, pressure square hole fillet, half blanking, the pressure diaphragm spring continuous punching die of bull nose and a levelling machine.Described diaphragm spring continuous punching die (as Fig. 2 and Fig. 3) comprises patrix 1, counterdie 2, described patrix 1 comprises upper bolster 11, first abnormal-shaped punch assembly 12, second abnormal-shaped punch assembly 13, square hole fillet convex template 14, centre bore punch-head assembly 15, pre-cut assembly 16 and cylindrical fillet convex template 17, described first abnormal-shaped punch assembly 12, second abnormal-shaped punch assembly 13, square hole fillet convex template 14, centre bore punch-head assembly 15, pre-cut assembly 16 and cylindrical fillet convex template 17 are fixed on described upper bolster 11 by screw successively, and described counterdie 2 comprises die shoe 21, first special-shaped die 22, second special-shaped die 23, square hole fillet concave template 24, centre bore concave template 25, pre-cut die 26, horizontally push away manipulator 27 and cylindrical fillet concave template 28, described first special-shaped die 22, second special-shaped die 23, square hole fillet concave template 24, centre bore concave template 25, pre-cut die 26, horizontally push away manipulator 27 and cylindrical fillet concave template 28 is fixed on described die shoe 21 by screw successively.
Step S2: raw material are carried out smoothing process by levelling machine.Raw-material flatness after levelling machine process is between 0mm to 0.3mm.Prevent raw material from blocking on continuous punching die.
Step S3: the raw material after step S2 process are delivered to and described diaphragm spring continuous punching die carries out jet-bedding and rush square hole.First rush a part of groove and square hole, after treating that this part groove and square hole have rushed, then rush groove and the square hole of another part, prevent the insufficient strength of diaphragm spring continuous punching die, cause product defective.
Step S4: the raw material after step S3 process are carried out pressure square hole fillet on described diaphragm spring continuous punching die; The radius of described fillet between 1mm ~ 1.5mm, improving product qualification rate.
Step S5: the raw material after step S4 process are carried out the centre bore rushing diaphragm spring on described diaphragm spring continuous punching die;
Step S6: the raw material after S5 step process are carried out pre-cut blanking on described diaphragm spring continuous punching die; Cut from raw material by semi-finished product diaphragm spring.
Step S7: utilized by the raw material after S6 step process the horizontal manipulator 27 that pushes away laterally to be pushed into next station;
Step S8: the raw material after S7 step process are carried out pressure cylindrical fillet on described diaphragm spring continuous punching die.The radius of described fillet between 1mm ~ 1.5mm, improving product qualification rate.
During work, the downward punching press of patrix, stamping-out is carried out to different die simultaneously, after stamping-out, feeder exports a step pitch, namely raw material move a step pitch, and the horizontal workpiece extremely next station pushed away on this station of the horizontal release of manipulator after raw material have moved, diaphragm spring continuous punching die released by the workpiece simultaneously next station upper punch cut out.
This kind of blanking method, uninterrupted stamping-out, carrying out stamping-out again without the need to raw material being cut into certain length, raw-material utilization rate can be promoted to 80% continuously.Simultaneously without the need to adopting how secondary mould and punch press, only need a secondary mould and a punch press, cost is low.Continuous seepage product, makes its production efficiency high.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to do, is directly or indirectly used in the technical field that other are relevant, all in like manner within scope of patent protection of the present invention.
