Abstract
The utility model discloses a novel long hinge rolling die. The novel long hinge rolling die comprises an upper die and a lower die, wherein the lower surface of the upper die is fixed with a male die structure through a fastening bolt; a trapezoidal bulge is formed on the lower part of the male die; a semicircular inwards concave forming groove is formed at a middle position of the lower part of the male die; a pressing block which corresponds to the trapezoidal bulge and is provided with a trapezoidal groove is arranged on one side of the corresponding lower die, and a female die is formed beside the pressing block; and a core rod is arranged at a forming position of the female die. The novel long hinge rolling die is simple in process, convenient to process and easy to assemble.
Description
Technical field
The utility model relates to volume circle technical field of mold, is specially a kind of novel band andgudgeon chain volume circle mould that is suitable for band andgudgeon chain volume circle.
Background technology
In the locomotive converted products, usually can use hinge arrangement between the connecting components, this hinge arrangement all is need to carry out brake forming to sheet material to make usually.But the workpiece that manually-operated obtains loses circle easily, therefore need to roll up circle to sheet material and process, to satisfy the needs of hinge normal operation.
In the prior art, the volume circle equipment of general hinge only is appropriate to the hinge of general length and the volume circle of short hinge usually, for the hinge of longer size, because the relative working (finishing) area of sheet material is larger, so that resistance and side force that processing runs into are larger, simultaneously, the power of processing section is also big or small inhomogeneous, the sudden change so that sheet material slides easily, thus make the sheet material sudden change of sliding easily, thereby cause the axiality of hinge inner hole and linearity, precision to reduce, the product defect rate improves.
The utility model content
The technical problem that the utility model solves is to provide a kind of novel band andgudgeon chain volume circle mould, 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 novel band andgudgeon chain volume circle mould comprises patrix and counterdie, and wherein, the patrix lower surface is fixed with a punch structure by fastening bolt, and the punch bottom has a trapezoidal projection, also has a semicircular indent forming tank in the punch lower middle position simultaneously; And corresponding counterdie one side also at the other die that has of binder block side, also is provided with a plug at the shaping position place of die simultaneously except having the binder block with trapezoidal groove corresponding with above-mentioned trapezoidal projection.
In the utility model, described binder block bottom is provided with the pool of buffer spring.
In the utility model, the side of described binder block and die side is respectively arranged with baffle plate and gripper shoe is reinforced.
Beneficial effect: the utility model can effectively be finished the volume circle moulding of band andgudgeon chain section bar, can the different thickness section bars of moulding the large linkage of change of shape simultaneously, and stability is high, fraction defective is low.
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.
Roll up the preferred embodiment of circle mould referring to a kind of novel band andgudgeon chain of Fig. 1, in the present embodiment, punch 2 is fixed on the cope match-plate pattern 1 by trip bolt, binder block 6 on its underpart and the lower bolster 5 agrees with, binder block 6 bottoms are provided with return spring 7 and cooperate punch 2 to be used for auxiliary positioning, and be provided with a plug 10 on the die 9 of moulding, cooperate the groove on the punch 2 to be used for the moulding of volume circle.
In the present embodiment, die 9 is connected with lower bolster 5 by backing plate 8 and set bolt, simultaneously, is respectively arranged with baffle plate 3 and gripper shoe 4 is reinforced spacing by the side of binder block 6 and die 9.
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.
