Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In order to reach the purpose of this utility model, as shown in Figure 1-2, in the first embodiment of a kind of flanging hole forming mould of the utility model, it comprises upper die and lower die, and patrix from top to bottom comprises the upper bolster 11, upper padding plate 12, train wheel bridge 13, baffle plate 14 and the stripper plate 15 that are connected successively; Counterdie from top to bottom comprises the lower bolster 21, lower bolster 22 and the die shoe 23 that are connected successively; Patrix is provided with the drift 3 for punching press flanging bore 6, and counterdie is provided with de-material thimble 4 and die plate insert 5, and die plate insert 5 is provided with the punching 51 corresponding with drift about 3, and de-material thimble 4 is arranged in punching 51; Be provided with back-moving spring below de-material thimble 4, the top of de-material thimble 4 is provided with frustum 41, and the upper end diameter of frustum 41 is less than lower end diameter, and the upper end diameter of frustum 41 is less than the internal diameter of flanging bore 6.Wherein, die plate insert 5 is fixed on lower bolster 21 by stopping payment screw 8.
Above-mentioned embodiment, the design of frustum 41 structure, the diameter of its frustum 41 upper end is less than the internal diameter of flanging bore 6, make product when de-material, de-material thimble can not the flange sidewall of direct contact product, and de-when expecting, because frustum is just in time positioned at the inner side of flanging bore, prevent hole wall to internal strain, substantially increase the internal diameter precision of flanging bore, improve the quality of product.Above-mentioned flanging hole forming mould, because the machining accuracy of its flanging bore is high, is also specially adapted to the flanging bore processing of thin material product.
In order to optimize implementation result of the present utility model further, as shown in Figure 1-2, in the second embodiment of a kind of flanging hole forming mould of the utility model, the range of taper of frustum is 20 °-40 °, such setting, when making product take off material, frustum 41 can enter the inner side of flanging bore 6 smoothly, under the drive of de-material thimble 4, successfully carry out de-material; Meanwhile, due to the support of frustum 41, during de-material, the reaction force of punching 51 pairs of products also can not make the sidewall of flanging bore 6 inwardly deformation occur, and affects its machining accuracy.
In order to optimize implementation result of the present utility model further, in the third embodiment of a kind of flanging hole forming mould of the utility model, the height of frustum 41 is greater than the flange height of flanging bore 6; Such setting, makes frustum 41 fully contact with flanging bore 6, and the effect of stress of punching 51 when taking off material to resist, improves distortion-free effect further.
In order to optimize implementation result of the present utility model further, as shown in Figure 3, in 4th kind of embodiment of a kind of flanging hole forming mould of the utility model, vertically, punching 51 comprises the bellmouth 511 be positioned at above die plate insert 5 and the through hole 512 be positioned at below die plate insert 5, through hole 512 is connected with bellmouth 511 and communicates, the upper end diameter of bellmouth 511 is greater than lower end diameter, such setting, make product when de-material, due to the setting of bellmouth 511, product is not vulnerable to the reaction force of die plate insert 5 or extruding force and the deformation occurred to the inside, further increase the machining accuracy of flanging bore.
Introduce operation principle of the present utility model below: during work, patrix is descending, stripper plate 15 pushes down material, drift 3 is punching flanging bore 6 downwards, the effect that de-material thimble 4 overcomes back-moving spring 7 under the effect of drift 3 is stepped down downwards, die plate insert 5 is due to the setting of bellmouth 511, and it gives lateral force on the sidewall of flanging bore 6, the material stress state of the sidewall sections of flanging bore 6 is changed; When bottom dead centre crossed by drift 3, when starting backhaul, drift 3 is first drawn back, and de-material thimble 4 withstands drift 3 upwards return under the effect of back-moving spring 7, and due to the setting of frustum 41 on de-material thimble 4, now de-material thimble 4 does not contact the sidewall of flanging bore 6; When stripper plate 15 return completely by drift 3, time on stripper plate 15 starts to motion, frustum 41 will be positioned at the inner side of flanging bore 6, and withstand flanging bore 6, flanging bore 6 is ejected die plate insert 5, just by the setting because of bellmouth 511, de-material power is compared to much smaller during conventional design, and the distortion therefore caused by de-material power reduces relatively; Meanwhile, due to the setting of the frustum 41 of de-material thimble 4, make it withstand flanging bore 6, and support in the inside of flanging bore 6, make flanging bore 6 that inside contraction not occur, ensure the tip dimensional accuracy of flanging bore 6.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
