Abstract
The utility model relates to a double-ended hinge rod processing module which mainly comprises an upper die and a lower die. The middle part of the upper die adopts a plane, and bulges are arranged at two ends of the upper die; the surface of each bulge facing to the die closing direction adopts a first circular arc surface; the lower die is symmetrical to the upper die in shape; bulges are arranged at two ends of the lower die, the surface of each bulge facing to the die closing direction adopts a second circular arc surface; lateral dies are symmetrically arranged on two sides of the upper die and the lower die; a third circular arc surface matched with the first circular arc surface and the second circular arc surface is arranged on the surface of the lateral die facing to the die closing direction; and the first circular arc surface, the second circular arc surface and the third circular arc surface form a complete cylinder space. By adopting the structure, the shape of a double-ended hinge rod is limited through an inner space formed by the upper die, the lower die and the lateral die; and particularly, the production process of a hinge structure of the double-ended hinge rod is effectively controlled through inverted cylinder spaces on two sides of the mould.
Description
Technical field
The utility model relates to a kind of mould and processing method, particularly a kind of double-head hinge bar processing mold.
Background technology
It is a kind of more common mechanical connecting structure that hinge connects, and existing hinge connection generally all is made by the iron sheet bending, and it is thinner to make the material that uses, and material is softer, than being easier to bending, making side.Because material is softer, this hinge connects cooperation and has the gap easily, is not very accurate, and this will directly have influence on the quality of final products.And hinge connects and will bear horizontal stressedly toward contact, and under long-time operating position, hinge axis tends to slowly big the support of hinged hole, and it is increasing to cause hinge to connect the gap that cooperates, and has a strong impact on user's experience.If can use thicker materials processing to be in the hinge connection, above problem will be avoided, and for thicker material, its hardness is relatively also higher, volume also can be bigger, also do not have a kind of method preferably to process its hinge arrangement at present, make it effectively to bend to hollow cylindrical structure and be used for the hinge cooperation.
The utility model content
The purpose of this utility model be a kind of convenience is provided in order to solve above-mentioned deficiency, effectively, accurately be that the material bending of 5-10mm becomes complete hollow cylinder to be used for hinge to connect with thickness, and the double-head hinge bar processing mold that can process simultaneously at the sheet material two ends.
In order to achieve the above object, the double-head hinge bar processing mold of the utility model design mainly comprises upper die and lower die, and described patrix middle part is the plane, is provided with protuberance at its two ends, and protuberance is first arc surface to the face of matched moulds direction; Counterdie shape and patrix shape symmetry are provided with protuberance at the two ends of counterdie, and protuberance is second arc surface to the face of matched moulds direction; Be provided with side form in the upper die and lower die bilateral symmetry, side form is provided with the three-arc face that cooperates with first arc surface and second arc surface to the face of matched moulds direction, and described first arc surface and second arc surface and three-arc face are formed a complete cylindrical space.The inner space that this structure is formed by upper die and lower die and side form, the shape, particularly mould that the limits double-head hinge bar volume cylindrical space of leaning now to one side, then to the other is controlled the production process of the hinge arrangement of double-head hinge bar effectively.
Further, behind described upper die and lower die and the side form matched moulds, between upper die and lower die, leave the cuboid space, be provided with the cylindrical space that forms by upper die and lower die and side form at these two ends, cuboid space.The both sides of counterdie are provided with the projection of fixation workpiece, conveniently add the fixation workpiece in man-hour.
The double-head hinge bar processing mold that the utility model is designed, simple in structure, reasonable in design, easy to use, can effectively be that the sheet metal of 5-10mm bends to double-head hinge bar with thickness, strengthened the intensity and the precision of hinge engaging structure greatly.In sum, the double-head hinge bar processing mold that the utility model is designed, a kind of hinged new processing thought is provided, the material thickness of hinge engaging structure has been expanded a new height, increase hinged reliability greatly, made hinge connect in the field widely that can be employed.

The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As Fig. 1, Fig. 2, shown in Figure 3, the double-head hinge bar processing mold that present embodiment is described mainly comprises patrix 1 and counterdie 2, and described patrix 1 middle part is the plane, is provided with protuberance at its two ends, and protuberance is first arc surface 3 to the face of matched moulds direction; Counterdie 2 shapes and patrix 1 shape symmetry are provided with protuberance at the two ends of counterdie 2, and protuberance is second arc surface 4 to the face of matched moulds direction; Be provided with side form 5 at patrix 1 and counterdie 2 bilateral symmetry, side form 5 is provided with the three-arc face 6 that cooperates with first arc surface 3 and second arc surface 4 to the face of matched moulds direction, and described first arc surface 3 and second arc surface 4 and three-arc face 6 are formed a complete cylindrical space 7.
Behind described patrix 1, counterdie 2 and side form 5 matched moulds, between patrix 1 and counterdie 2, leave the cuboid space, be provided with the cylindrical space 7 that forms by patrix 1, counterdie 2 and side form 5 at these two ends, cuboid space.The both sides of counterdie 2 are provided with the projection 8 of fixation workpiece.
During work, bar plate body 9 two ends that will make moulding earlier strike out crooked circular-arc, bar plate body 9 with this bending two ends is placed on the counterdie 2 of double-head hinge bar processing mold then, then patrix 1 presses down and counterdie 2 matched moulds, the bar plate body 9 of bending two ends is completely fixed between counterdie 2 and the counterdie 2, next step is the side form 5 simultaneously inside matched moulds on both sides again, the three-arc face 6 of side form 5 is pushed the sweep 10 at bar plate body 9 two ends, the sweep 10 at bar plate body 9 two ends is inwardly curled, first arc surface 3 at the double-head hinge bar processing mold, under the effect of the cylindrical space 7 of the composition of second arc surface 4 and three-arc face 6, bend to a hollow cylinder.Wherein, described patrix 1 and side form 5 drive by hydraulic jack.
