Abstract
The utility model relates to a novel hinge pre-bending mould which comprises an upper template and a lower template, wherein a square steel structural concave mould is arranged on the lower template; a convex mould is arranged on the upper template; a groove which is jointed with a corner of the concave mould is milled in a corner position on the convex mould adjacent to the concave mould; a double-layer steel structure is fixedly arranged on the upper part of the concave mould and aside the convex mould; a baffle is arranged aside the concave mould; a cavity is encircled by the baffle structure, the concave mould and the convex mould; a detaching bolt is arranged in the cavity; and a resetting spring is arranged on the detaching bolt. The novel hinge pre-bending mould has a novel structure, is convenient to process, is suitable for a hinge in bigger size or made of thicker material and is capable of effectively increasing the quality of the hinge end product and the bending precision.
Description
Technical field
The utility model relates to mould applications, is specially a kind of new hinges die for fisrt forming.
Background technology
In general, a kind of in the more common syndeton of mechanical field during chain connection, existing chain connection generally all is to be made by the iron sheet bending.In existing technique, typically use thinner flexible material and make, because material is softer thinner, thereby than being easier to brake forming.Simultaneously, owing to the also reason of material, this chain connection cooperates and has easily the gap, it not is very accurate causing connecting, thereby be only suitable in family expenses or some fit clearance and the less demanding field of quality of fit are not suitable for industrial circle to the high-precision requirement of relevant connection structure high strength.
In industry, need to utilize thicker and rigidity and hardness with respect to materials processing become hinge to avoid the problems referred to above, because the material that uses is thicker, its hardness is also relatively high simultaneously, volume is also relatively large, thereby directly material is carried out bent into shape and cause easily Materials Fracture, thereby affect yield rate.Thereby, need a kind of novel die of design in order to raw material are carried out pre-bending, add the hard impulsive force in man-hour and the internal stress of material with minimizing, finally improve the yield rate of final products.
The utility model content
The technical problem that the utility model solves is to provide a kind of new hinges die for fisrt forming, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of new hinges die for fisrt forming comprises cope match-plate pattern and lower bolster, wherein, is provided with a square bar structure die on the lower bolster, and is provided with a punch at cope match-plate pattern; The corner location adjacent with die is milled with the groove of an applying die corner on the described punch; Simultaneously, on die top, the other pair of lamina steel construction that also is fixed with of punch side, the upper strata of clad steel structure is the fixed head fixing with cope match-plate pattern, understructure is holding pad, be inserted with hexagon socket head cap screw in the holding pad, and in the middle of the clad steel structure, also be provided with a rubber mount, so that the laminated flitch can be done moving up and down of little stroke at vertical plane under the effect of hexagon socket head cap screw and rubber mount; And being provided with a block on die side side, stop block structure and die and punch are separated out a cavity jointly, are provided with a unloading bolt in the cavity, are provided with return spring on the unloading bolt.
In the utility model, the hexagon socket head cap screw that inserts in the described laminated flitch also overlaps outward a contour cover, excessive in order to prevent fixed head and holding pad stroke.
In the utility model, described punch side is other to be provided with limited post, and limited post is fixed by bolt and cope match-plate pattern, in order to carry out spacing to punch.
Beneficial effect: the utility model is simple in structure, reasonable in design, easy to use, can realize the pre-bending of thicker degree metallic plate, makes in order to convenient follow-up hinge, guarantee the strength and stiffness of its hinge finished product, simultaneously, can effectively prolong the service life of hinge finished product, improve its quality of fit.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of new hinges die for fisrt forming of Fig. 1, in the present embodiment, both sides on the lower bolster 1, be respectively arranged with back-up block 3, simultaneously, between two back-up blocks 3, be fixed with a backing plate 2 by set bolt, contour die 4 and block 14 are installed on the backing plate 2, stripper bolt 16 is then passed backing plate 2 and is arranged between die 4 and the block 14, and spacing by return spring 15, and also is provided with location ejection block 13 at stripper bolt 16 tops.
And in the part of the upper die, distinguish mounting plate 6, punch 11 and limited post 12 by bolt on the cope match-plate pattern 7, wherein, be used for overlapping on the hexagon socket head cap screw 9 of mounting plate 6 a contour cover 8 is arranged, contour cover 8 extends to holding pad 5 parts always, and between holding pad 5 and fixed head 6, also cover has a rubber mount 10.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. a new hinges die for fisrt forming comprises cope match-plate pattern and lower bolster, it is characterized in that, is provided with a square bar structure die on the lower bolster, is provided with a punch on the cope match-plate pattern; The corner location adjacent with die is milled with the groove of an applying die corner on the described punch; Simultaneously, on die top, the other pair of lamina steel construction that also is fixed with of punch side, the upper strata of clad steel structure is the fixed head fixing with cope match-plate pattern, understructure is holding pad, is inserted with hexagon socket head cap screw in the holding pad, and also is provided with a rubber mount in the middle of the clad steel structure, and at the other block that is provided with of die side, stop block structure and die and punch are separated out a cavity jointly, are provided with a unloading bolt in the cavity, are provided with return spring on the unloading bolt.
