The utility model content
The utility model problem to be solved provides a kind of diaphragm spring grooving mould, overcomes the problems referred to above that exist in the prior art.
A kind of diaphragm spring grooving mould of the utility model; Comprise upper die component and following membrane module; Upper die component comprises cope match-plate pattern, upper padding plate and is fixed on the punch on the upper padding plate; Membrane module comprises lower bolster, lower bolster and is fixed on the die on the lower bolster under said, and said punch and die match, and said punch is made up of a plurality of submodules; Each submodule comprises long mould that forms elongated slot on the diaphragm spring and the casement that forms hole on the diaphragm spring, and long mould and casement are fixedly linked with said upper padding plate respectively; All submodule height are spaced apart, and the difference in height of adjacent two submodules is less than the material thickness of making said diaphragm spring.Adopt split type punch, disassembly and assembly are convenient, and through height setting spaced apart, the impulsive force in the time of can reducing stamping-out improves punching precision.
The cutting edge of the said long mould of the utility model is the inclination cutting edge, and the height of said long mould and said casement sides adjacent is greater than the height of said long mould opposite side.
The said upper padding plate of the utility model below is provided with a lead, and said die is provided with pilot hole, and said lead inserts in the pilot hole of said die when upper and lower mould combines.
The blade clearance of the said grooving mould of the utility model is 18% of a said material thickness.
The said lower bolster of the utility model is provided with centre bore, is provided with one in the centre bore and inserts, and said inserting is provided with material spilling hole.
Through above technical scheme, a kind of diaphragm spring grooving mould of the utility model, it has following beneficial effect:
(1) adopt split type jet-bedding punch, make die change quick, repair a die conveniently, assembling is simple; This punch adopts height spaced apart, and the impulsive force in the time of can reducing stamping-out improves punching precision;
(2) blade of above-mentioned long mould is an inclined edge, so this punch adopts the oblique impact mode towards the elongated slot of diaphragm spring the time, and the surge when having reduced scouring abrasion improves punching precision;
(3) blade clearance of this grooving mould adopts specific gap to make the unitary mould life-span improve 2-3 doubly.
(4) the diaphragm spring quality of this grooving die production is good, and part has higher surface quality and dimensional accuracy.

The specific embodiment
As shown in Figure 1; A kind of diaphragm spring grooving mould of the utility model; Comprise upper die component and following membrane module, upper die component comprises cope match-plate pattern 1, upper padding plate 2 and is fixed on the punch on the upper padding plate that following membrane module comprises lower bolster 5, lower bolster 9 and is fixed on the die 4 on the lower bolster; Punch and die match; Punch is made up of a plurality of submodules, and each submodule comprises long mould 7 that forms elongated slot on the diaphragm spring and the casement 8 that forms hole on the diaphragm spring, and long mould 7 is fixedly linked with upper padding plate 2 respectively with casement 8; All submodule height are spaced apart, and the difference in height of adjacent two submodules is less than the material thickness of making diaphragm spring.The punch of the utility model is made up of a plurality of independently submodules; Each submodule is again according to different growth mould and the casements of dividing of the stamping forming shape of institute; This split type punch disassembly and assembly are convenient; And through the setting spaced apart of submodule height, the impulsive force in the time of can reducing stamping-out improves punching precision.
Like Fig. 2 and shown in Figure 3; The cutting edge of long mould 7 is the inclination cutting edge, and generally about 2 °, the height h1 of long mould 7 and casement sides adjacent is greater than the height h2 of long mould opposite side for the tilt angle alpha of cutting edge; Promptly long mould is when the elongated slot of blanking die flat spring; Long mould cutting edge is to contact with the material of making diaphragm spring gradually, therefore, and the impulsive force when having reduced stamping-out.As Fig. 4 and shown in Figure 5 be the shape of above-mentioned casement.According to the groove number of manufacturing diaphragm spring the height proportioning of submodule is set, as shown in Figure 6, with diaphragm spring 10 18 elongated slots 12 and 18 holes 11 being arranged is example; Then punch has 18 submodules, and it is nine high nine low that 18 submodules are made, and height is spaced apart; When stamping-out, high submodule contacts with the material of making diaphragm spring earlier carries out stamping-out, stamping-out after the low submodule; Impulsive force when having reduced stamping-out prevents the stamping-out distortion.
Above-mentioned upper padding plate 2 belows are provided with a lead 3, and die 4 is provided with pilot hole 41, and lead 3 inserts in the pilot hole 41 of dies when upper and lower mould combines, the punching precision that has guaranteed the grooving mould that cooperates of this lead and the mould that leads.The blade clearance of this grooving mould is 18% of a material thickness, has improved the service life of grinding tool.
Above-mentioned lower bolster 5 is provided with centre bore, is provided with one in the centre bore and inserts 6, inserts 6 to be provided with material spilling hole, through on lower bolster, adding inserting of band material spilling hole, can be convenient for changing, and has improved the intensity of lower bolster, and has improved the service life of this grooving mould.
More than diaphragm spring grooving mould that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, on the specific embodiment and range of application, all can change to some extent, so this description only is used in the utility model embodiment is described; Should not be construed as the restriction to the utility model, all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
