Description
Technical field
The present invention relates to a kind of machined die is and in particular to a kind of S-shaped spring extrudes blanking die.
Background technology
Also known as serpentine spring, its elastic force is superior to coil spring to S-shaped spring, and shortcoming is shaky.It is applied to the sofa base making sofa backrest or having cushion.Existing S-shaped spring is formed generally by steel wire winding bending, needs special bender to carry out bending and molding, and is a continuous banding after being molded, according to the actual needs, the S-shaped spring of banding is sheared, is formed single spring, in next step production process.In prior art, need special bender to be wound bending to steel wire, increased processing cost, and the precision of the typically bender bending of low cost is poor, it is difficult to ensure that product quality.The burden of enterprise can be increased using expensive bending equipment, applicability is poor.Furthermore, formed after bending is continuous band-shaped, needs special cutter shear forming, and one carries out shearing needing to purchase cutter, and two can increase processing cost increased shearing step, reduce production efficiency, are unfavorable for improving the competitive advantage of enterprise.
Content of the invention
It is an object of the invention to provide a kind of S-shaped spring extrudes blanking die, change existing processing mode, extruding is achieved by special mould and is punched one-time formed processing mode.
For reaching above-mentioned purpose, the technical scheme is that：S-shaped spring extrudes blanking die, including upper die and lower die, described lower mould is stent, described upper mould is movable mold, described lower mould includes lower mode cavity, and described upper mould includes the upper module with lower mode cavity cooperation, and described lower mode cavity includes the lower die cavity of U-shaped, described lower die cavity be symmetrically arranged on two with semicircular projection, described raised outside is connected with down cut mouth；Described upper module includes the upper protruding block with the cooperation of lower die cavity, the upper die cavity being symmetrically arranged on two with male cooperation of described upper protruding block, and the outside of described upper die cavity is connected with shear blade.
The processing mode of S-shaped spring, during using technique scheme, is revolutionized from processing mode.Abandon the mode of traditional curling bending, by the mating reaction of upper die and lower die, using upper module and the shaping of lower mode cavity extruded cords, the process velocity of S-shaped spring can be greatly improved by the molding mode of extruding, and without manually being extruded in process, labour can be saved.Furthermore, due to being provided with down cut mouth and upper shear blade, while upper and lower mould is extruded, unnecessary steel wire direct shearing is fallen by down cut mouth and upper shear blade.Just unnecessary steel wire can be sheared it is achieved that one-off is molded so while extrusion molding, working (machining) efficiency greatly improves, and machining accuracy is higher.
Prioritization scheme further, described raised outside connects down cut side, and the described raised intersection with down cut side forms down cut mouth.Form sheared edge to be easy to process and safeguard by down cut side.
Prioritization scheme further, the outside of described upper die cavity connects upper sheared edge, and described upper die cavity forms shear blade with the intersection of upper sheared edge.Form shear blade to be easy to process and safeguard by upper sheared edge.
Prioritization scheme further, described down cut side is 20 ° with the angle of horizontal plane.
Prioritization scheme further, described upper sheared edge is 30 ° with the angle of horizontal plane.
Different angles are set, primarily to forming a shearing seam accommodating shearing material after matched moulds between down cut side and upper sheared edge.
Prioritization scheme further, the bottom surface of described lower die cavity is semicircle cambered surface, and the diameter of described semicircle cambered surface is identical with the diameter of upper die cavity.The above-mentioned uniformity being disposed to guarantee S-shaped spring force.
Brief description
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1 is the schematic cross-section that S-shaped spring of the present invention extrudes blanking die embodiment；
Fig. 2 is the use state schematic diagram of Fig. 1.
Reference：Upper mould 1, lower mould 2, upper die shank 3, deep trouth 4, raised 5, down cut side 6, projection 7, shallow slot 8, upper sheared edge 9, steel wire 10.
Specific embodiment
As shown in figure 1, S-shaped spring of the present invention extrudes blanking die, including the upper mould 1 using cooperatively and lower mould 2.Upper mould 1 can be driven by upper die shank 3 for movable mold and move up and down.Lower mould 2 is cover half, is fixed on irremovable on base.Offer a bending chamber in lower mould 2, form the deep trouth 4 of a U-shaped in this bending chamber, the bottom of deep trouth 4 is arc.In bending chamber, the both sides positioned at deep trouth 4 are symmetrically arranged with the projection 5 of two arcs, and the outside raised 5 forms down cut portion, and there is the down cut side 6 of an inclination in down cut portion, and down cut side 6 forms sheared edge with the intersection of projection 5.One downward bending part is formed on upper mould 1, in this bending part, forms the projection 7 of a U-shaped, projection 7 may be inserted in deep trouth 4.It is symmetrically arranged with the shallow slot 8 of two arcs in the both sides of projection 7, shallow slot 8 and raised 5 cooperations are so that raised 5 may be inserted in shallow slot 8.Cut part on the outside of shallow slot 8 is formed, there is the upper sheared edge 9 of an inclination upper cut part, and upper sheared edge 9 forms shear blade with the intersection of shallow slot 8.The angle wherein going up sheared edge 9 with horizontal plane is more than the angle on down cut side 6 and horizontal plane so that after upper mould 1 and the 2-in-1 mould of lower mould, forming a shearing seam between upper sheared edge 9 and down cut side 6.The angle being typically chosen sheared edge 9 with horizontal plane is 30 °, and down cut side 6 is 20 ° with the angle of horizontal plane.
As shown in Fig. 2 when using, steel wire 10 is placed on the positioning device, steel wire 10 is kept to be located between upper mould 1 and lower mould 2.Operation actuating unit, presses downwards mould 1, and the projection 7 on upper mould 1 takes the lead in contacting and extruded cords 10, and steel wire 10 is gradually pressed in lower mould 2.Till upper mould 1 and the complete matched moulds of lower mould 2.In die-closed position, under the mating reaction with deep trouth 4 for the projection 7, and in the presence of two projections 5 and two shallow slots 8, steel wire 10 is squeezed into shape to be processed.And, the mating reaction by upper sheared edge 9 and down cut side 6, the steel wire 10 entering shearing seam exceeding is cut off at shear blade and sheared edge.The product obtaining can be directly entered next manufacturing procedure.
The present invention revolutionizes the processing mode of S-shaped spring from processing mode.Abandon the mode of traditional curling bending, by the mating reaction of upper mould 1 and lower mould 2, using bending part and the shaping of bending chamber extruded cords, the process velocity of S-shaped spring can be greatly improved by the molding mode of extruding, and without manually being extruded in process, labour can be saved.Furthermore, due to being provided with down cut mouth and upper shear blade, while upper and lower mould is extruded, unnecessary steel wire direct shearing is fallen by down cut mouth and upper shear blade.Just unnecessary steel wire can be sheared it is achieved that one-off is molded so while extrusion molding, working (machining) efficiency greatly improves, and machining accuracy is higher.
Above-described is only the preferred embodiment of the present invention; it should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some deformation can also be made and improve; these also should be considered as protection scope of the present invention, and these are all without the effect affecting present invention enforcement and practical applicability.
