Embodiment
In order to make the technician of this area understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
The drawing die of a kind of rear floor front stiffener provided for the utility model embodiment as seen in figures 3-6, comprise patrix 3, counterdie 1 and flanging circle 2, patrix 3 comprises die holder 32, die 31, counterdie 1 comprises lower die holder 12, punch 11, punch 11 has punch surface 111, die 31 has die profile 311; Punch surface 111 comprises the first punch surface and the 2nd punch surface, and the first punch surface and the 2nd punch surface connect to form mutual process complementary surface to joining; Die profile 311 comprises the first die profile and the 2nd die profile, and the first die profile and the 2nd die profile connect to form mutual process complementary surface to joining; First punch surface and the first die positive form the first pressing part, and the 2nd punch surface and the 2nd die positive form the 2nd pressing part, and the first pressing part and the 2nd pressing part are respectively for the formation of the first drawing part 03 and the 2nd drawing part 04. Specifically for punch surface, it is possible to by the punch surface of floor front stiffener single-piece drawing after two one of them rotate 180 ° after with another to spelling, flange in outside, flange is merged together in inner side, thus forms the punch surface shown in Fig. 3.
As Figure 7-8, the punching press of this drawing die form two after floor front stiffener, and in punching course both be connected together to joining, mutually as process complementary surface. Compared to single-piece drawing technique, the drawing die that the utility model provides, its punch surface 111 and die profile 311 are spliced by two portions, and complete drawing die face can be formed after splicing, playing the effect mutually supplemented makes die face more smooth-going, and the drawing part of correspondence no longer needs to arrange bigger process complementary surface, thus reduce the accounting of process complementary surface, save material cost. In addition, this structure can complete the shaping of two parts in a secondary mould simultaneously, improves production efficiency simultaneously.
Again as shown in Figure 7, three masks of rear floor front stiffener have flange, one side for flange face, in design process, part splices by illustrated orientation, flange is expanded on the face vertical with pressing direction, in the middle of two parts, cutting part reserves waste material width, the flange of both sides expects that back gauge punch 11 rounded tip stays waste material width equally after launching in addition, and then using the flange face of part as binder surface, flange periphery reserves certain distance to drawing muscle medullary ray;Accordingly, in mould structure, flanging circle 2 is for contacting with the material forming rear floor front stiffener flange face, first punch surface and the 2nd punch surface to spelling junction, with being coordinated spelling junction of the first die profile and the 2nd die profile, form above-mentioned flange part. So not only make mould structure compacter, and minimum process complementary surface can be obtained, save material cost further.
Preferably, above-mentioned first pressing part and the 2nd pressing part are axially symmetric structure, and the first pressing part and the 2nd pressing part connect along the diad direction of axially symmetric structure joining. The drawing of two parts can not only be completed like this, it is to increase material use efficiency and production efficiency one drawing operation simultaneously; And structure, the i.e. symmetrical drawing of double-piece axisymmetricly simultaneously of whole drawing die face, in drawing process, plate input speed and rate of deformation are more even, such that it is able to improve the quality of drawing part.
In addition, in the drawing die that the utility model embodiment provides, punch 11 is provided with the first wear-resisting plate 14, is processed with the first wear-resisting plate 14 in slide guide face 22, first in the die cavity of flanging circle 2 and the first slide guide face 22 is slidably matched. Punch 11 and flanging circle 2 are active connection, use procedure needs frequently dismount, therefore wear and tear relatively more serious, and above-mentioned wear-resisting plate can reduce loss, improve the work-ing life of mould itself, also can alleviate the workpiece accuracy decline problem because mould loss causes simultaneously.
Preferably, the die of drawing die is led and is provided with the 2nd wear-resisting plate 34 on leg, and the two ends of flanging circle 2 are processed with the 2nd wear-resisting plate 34 in slide guide face the 23, two and the 2nd slide guide face 23 is slidably matched. The loss of mould can be slowed down so further, increase the mould overall life-span.
As shown in Figure 3, the drawing die that the utility model embodiment provides, its lower die holder 12 is provided with multiple pier and extremely pads 13, and when mould needs pier real-time, pier extremely pads 13 pressure being used for bearing lathe and loading on mould; Each pier extremely pads 13 and evenly arranges along punch 11 periphery so that reactive force evenly.
Further, as shown in Figure 4, flanging circle 2 being provided with multiple pressure regulation pad 21, each pressure regulation pad 21 is arranged along binder surface periphery, pressure regulation pad 21 extremely pads 13 with pier and has the part contacted along die stamping direction, so that the pressure between adjustment flanging circle 2 and punch 11.
Further, as shown in Figure 5, upper die holder 32 is provided with multiple processing plane 33, each processing plane 33 is arranged along die 31 periphery, processing plane 33 has the part contacted with pressure regulation pad 21 along die stamping direction, so that the gap of adjustment between punch 11, die 31, control delivery speed, ensures drawing quality.
Only describe some one exemplary embodiment of the present utility model by the mode of explanation above, undoubtedly, for the those of ordinary skill of this area, when not deviateing spirit and scope of the present utility model, it is possible to by various different mode, described embodiment is revised. Therefore, above-mentioned accompanying drawing and description are being explanation property in essence, it should not be interpreted as the restriction to the utility model claims.
