The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1 and Fig. 2, a bending with sizing of the present invention is eliminated resilience mould, comprises upper module and the lower module of working in coordination, wherein, upper module comprises: the stripper plate 1, baffle plate 2, train wheel bridge 3 and the upper padding plate 4 that arrange from bottom to top, lower module comprises lower bolster 5.In lower bolster 5, be provided with a counterdie bending and enter piece 6 and a counterdie wedge 7, counterdie bending enters piece 6 and comprises holding plane 601 and the first bending side 602, consider the resilient nature of material, the first included angle A forming between holding plane 601 and the first bending side 602 is less than the target bending angle of product 13, such as, will be by product 13 bending to 90 degree, the first included angle A is 80-89 degree so, preferably 84 spend, this mould is first by product 13 bending to 84 degree, after the demoulding, product 13 resilience angle B under nature is 6 degree, thereby obtains the product 13 of bending 90 degree.Practical operation proves, error is minimum, and the quality of each batch products is all more stable.
Upper module and counterdie assembly are closed and could be realized bending operation, so, upper module also comprises a centering block holder 8 that runs through train wheel bridge 3, baffle plate 2 and stripper plate 1, the end of centering block holder 8 is fixedly connected with one can stretch out stripper plate 1 product 13 is carried out to the centering block tulwar 9 of bending, and centering block tulwar 9 has second bending side 901 parallel with the first bending side 602 when bending operation.Centering block tulwar 9 also has bottom surface 902 and the vertical plane 903 with the second bending side 901 adjacent settings, between the second bending side 901 and bottom surface 902, vertical plane 903, all adopt round-corner transition, thereby the transitionality while guaranteeing bending is good, can product 13 not be caused and be scratched or damage.
Preferably, centering block tulwar 9 is rotationally connected by a pivot pin 10 and the end of centering block holder 8.As a kind of improved plan, centering block holder 8 is hollow structure, and its inside is provided with an ejector pin 11, in upper padding plate 4, be provided with one and withstand the spring 12 of the end of ejector pin 11, so,, under die opening state, just can avoid centering block tulwar 9 to rotate and then interfere with lower bolster 5.
As shown in Figure 1, counterdie wedge 7 has an inclined-plane 701, and centering block tulwar 9 has progressive parallel with inclined-plane 701, and during bending, inclined-plane 701 contacts with progressive, can effectively prevent that centering block tulwar 9 from rotating or sliding, and further guarantees bending quality.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
