Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
Referring to fig. 1 and 2, a one-time bending forming die structure of a metal bracket comprises an upper base plate 1, a material pressing device 3, a spring 4, a male die 8, a reverse side block 10, a material ejecting device 11, a female die 14, a positioning plate 15 and a lower base plate 16, wherein the upper base plate 1 and the lower base plate 16 are connected with a guide post 9 through a guide sleeve 2, the guide sleeve 2 is connected with the guide post 9, the material pressing device 3 is connected with the spring 4, the spring 4 is connected with a material returning screw 5, the material pressing device 3 is connected with the male die 8 through a dovetail groove structure, the male die 8 is provided with a positioning pin 6, the lower base plate 16 is connected with the female die 14 and the reverse side block 10 in a groove, the material ejecting device 11 is connected with the female die 14 through the dovetail groove structure, the male die 8 is provided with a first stopper 7, the female die 14 is provided with a second stopper 13, a supporting rod 12 is connected below the ejector 11.
Specifically, the dovetail groove structure design shown in fig. 2 is adopted because the die structure is small, and accurate positions and matching relations are required between the material pressing device 3 and the male die 8, and between the material ejecting device 11 and the female die 14.
The utility model discloses a theory of operation does: before stamping, the ejector 11 is flush with the female die 14, and the material pressing device 3 is flush with the end face of the male die 8 under the action of the spring 4, or the material pressing device 3 is slightly higher; when stamping starts, a blank is tightly pressed and accurately positioned by the material pressing device 3 and the material ejector 11, an upper die descends, and the blank descends along with the material pressing device 3 and the material ejector 11 moves downwards to bend the left end of the blank firstly because the elasticity of the spring 4 on the selected material pressing device 3 is larger than that of the spring below the material ejector 11; the ejector 11 is continuously descended to enable the male die 8 to descend relative to the material pressing device 3, and the right end of the blank is bent and formed. When the material pressing device 3 is completely contacted with the upper bottom plate 1 and the material ejector 11 is completely contacted with the lower bottom plate 16, the whole product is corrected.
To sum up, the utility model has the advantages of the structure is little, low in manufacturing cost, and the blank is fixed a position accurately on the mould, and the terrace die atress is balanced.
