Abstract
The utility model relates to a metal plate mould bending anti-rebounding mechanism, which comprises a bending male, a bending female and an unloading block, wherein the bottom surface of the bending male is raised to form a frontal beading, and the bending male is also provided with a raised lateral beading at the side surface vertically intersected with the bottom surface provided with the frontal beading; the frontal beading is connected with one end of the lateral beading, and the other end of the lateral beading is connected with the surface of the bending male in an inclined transition manner; the included angle between the frontal beading and the inclined surface where the other end of the lateral beading is connected with the surface of the bending male in an inclined transition manner is less than 90 degrees. The metal plate mould bending anti-rebounding mechanism has the benefits that: the bending male in the bending mechanism is provided with the lateral beading corresponding to the frontal beading, the problem of effectively reducing the mobility at the deformation position of a product during the bending process of the mould is realized by matching of the original frontal beading, thus leading the plastic deformation to be easier; and simultaneously, the cold-work hardening is simultaneously carried out on the inner side of the product during the bending process, so that the rebounding generation of the product after bending is effectively reduced, and the bending precision is ensured.
Description
[technical field]
The utility model relates to a kind of panel beating mould, refers in particular to the anti-resilience mechanism of a kind of panel beating mould bending.
[background technology]
In the metal plate punching technology, often relate to and need carry out the bending processing sheet metal component, then panel beating bending angle, particularly the instability of the bending angle under the higher situation of flanging that needs the bending product is to perplex the hard nut to crack of industry for a long time.Because the instability of product bending angle not only can't guarantee the bending angle tolerance, also can have a strong impact on other related size.Attempting in the industry overcoming this problem for this reason always, wherein the front beading is being set and is extensively approved and be applied to improve bending angle precision mode by bending Gongshang at bending mechanism by the structure of the bending mechanism in the panel beating mould is improved.Even if yet adopted the bending mechanism of this kind structure, though can guarantee the requirement of flanging angle tolerance to a certain extent, but for the flanging height more than 50MM, the bending angle tolerance is not more than during 0.5 ° sheet metal component bending uses, still be difficult to reach requirement, can't satisfy the potential higher demand of client.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, provides a kind of precision the higher anti-resilience mechanism of panel beating mould bending that can effectively prevent product resilience in the bending process.
The purpose of this utility model is achieved in that the bending of a kind of panel beating mould prevents resilience mechanism, it comprises bending public affairs, bending mother and unloading block, the public bottom surface of bending has convexed to form the front beading, and its improvements are: the bending public affairs are provided with the side beading that side that beading bottom surface, front intersects vertically also is provided with projection in described; Described front beading links to each other with side beading one end, and the other end becomes the inclined-plane excessively to connect in the public surface of bending;
Described side beading length is not less than 0.5mm, is not more than 2mm;
Described side beading length is identical with front beading length;
The public surface of the described front beading and the side beading other end and bending excessively connection inclined angle is spent less than 90.
Than common panel beating mould bending mechanism, the beneficial effects of the utility model are to be provided with the side beading corresponding with the front beading for the bending public affairs in the bending mechanism, cooperation by original front beading, realized having effectively reduced product deformation place flowability problem in the mould bending process, made its plastic deformation easier; Simultaneously in the bending process to the inboard flow harden simultaneously of product, effectively reduced the generation of resilience after the product bending, guaranteed bending precision.

[specific embodiment]
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.
As shown in Figure 1, the utility model relates to the anti-resilience mechanism of a kind of panel beating mould bending, and it comprises bending public affairs 1, bending female 2 and unloading block 3, and wherein unloading block is used to place and treats the bending product.When bending mechanism uses at first bending public 1 the operation top is solid is downwards treating on the bending product, thereby bending then public 1 continues descending interlock unloading block 3 to be moved downwards, whole process bending mother 2 maintains static, thereby originally level treat the upwards bending under female 2 effects of the fixing bending in left side of bending product chance, form product 4 shapes after the bending as shown in the figure.And precision depends primarily on the structure of bending public affairs 1 in the whole bending process, referring to Fig. 2, the bottom surface of bending sky 1 has convexed to form front beading 101, the side that the corresponding bottom surface in front beading 101 intersects vertically also is provided with the side beading 102 of projection, this side beading 102 links to each other with an end of front beading 101, side beading 102 becomes the inclined-plane excessively to be connected with the other end of front beading 101 in public 1 surface of bending, this excessive connection inclined angle theta is less than 90 degree, forbid to meet at right angles, the right angle poor rigidity is unfavorable for that product separates from bending Gongshang.And the length of side beading and front beading is identical, and its length generally is not less than 0.5mm, is not more than 2mm.Side beading thickness S is then according to treating that the difference of the panel beating product thickness T machining tolerance of bending changes to some extent, and for example existing common process tolerance is T ± 0.025, so its regular value S=0.05MM.
As Fig. 3 is the embodiment schematic diagram on the panel beating mould that is applied to of the present utility model, bending public affairs 1 are installed on panel beating upper mould group 11 among this embodiment, female 2 correspondences of bending are fixedly set on the panel beating lower mould group 12,3 of described unloading block are in the stripper plate 3 of following module 12, following module 12 is positioned on the frame 9, and be connected with last module 11 by outer guiding post 10, and the stripper plate 3 of described down module 12 penetrates down re-packing on the making bar 15 and be arranged at frame 9 of module 12 by one and 14 links to each other, re-pack 14 and 9 of frames be provided with spring 16, thereby make whole stripper plate 3 in the pressing and bending process can link to each other re-pack up and down under the effect of 14 lower springs 16.
It is to be noted; the utility model is not limited to above-mentioned embodiment; for example bending public affairs; the bending mother is not limited to the application of embodiment panel beating mould; and can generally be applicable in all kinds of panel beating moulds; and its set-up mode is not limited to above-mentioned last module the bending public affairs is set; following module is provided with the bending mother; the structure of unloading block; as long as on; under be oppositely arranged described bending mechanism and can use; therefore any simple modification of in based on technical solutions of the utility model, the foregoing description being done of any those skilled in the art; equivalent variations and modification all belong in the protection domain of the present utility model.
