Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
Fig. 5 represents that the present embodiment provides rotation crimp mechanism structural representation, Fig. 6 represents the crimp process schematic rotating crimp mechanism in Fig. 5, Fig. 7 represents the forming process schematic diagram rotating crimp mechanism in Fig. 5, and Fig. 8 represents that schematic diagram opened by the mould rotating crimp mechanism in Fig. 5.
In conjunction with shown in Fig. 5 to Fig. 8, present embodiments provide a kind of rotation crimp mechanism, for plate to be processed is bent.Described rotation crimp mechanism includes straight line driving mechanism 1, rotary drive mechanism and upper mold 2, and straight line driving mechanism 1 is fixing with upper mold 2 to be connected, and driving upper mold about 2 moves linearly.The bottom of upper mold 2 is provided with strip groove (groove does not marks in the accompanying drawings), and the cross section of groove is circular arc, is specifically as follows semicircle.Being provided with the column revolving part 3 with groove fit in groove, rotary drive mechanism (not shown) is connected with revolving part, drives revolving part to rotate in groove.The cross section of revolving part is the sector that central angle is more than 180 degree.
Wherein, straight line driving mechanism 1 can pass through hydraulic power, electronic, internal combustion engine etc. is power.Upper mold 2 can be achieved a fixed connection by the clutch end of fixing screw, draw-in groove etc. with straight line driving mechanism 1, needs the dismounting being easy to upper mold 2 to replace according to different processing.Can be connected with the slide block being arranged on revolving part 3 by being arranged on the chute within strip groove between strip groove with revolving part 3, it is achieved revolving part 3 rotating relative to strip groove.
Rotating crimp mechanism and also include that lower mold 4, lower mold 4 include a first side corresponding with strip groove position, the angle on two surfaces that lower mold 4 is corresponding with first side is predetermined angle, and plate 6 to be processed is placed on the surface that first side is corresponding.The central angle angle of revolving part 3 determines according to reality processing plate bending angle, such as process square, then the fan-shaped central angle angle of revolving part 3 cross section is preferably 270 degree, and such as the plate of processing 60 degree, then the fan-shaped central angle angle of preferred revolving part 3 cross section is 300 degree.Lower mold 4 is for providing support to plate to be processed, and the bending realized plate 6 to be processed that matches with the sector of revolving part 3 cross section, concrete angle angle the most to be processed is 90 degree, then the angle on two surfaces that this lower mold 4 is corresponding with first side is less than 90 degree, it is achieved a few type beams processing of negative angle.
During bending, one end of revolving part 3 drives plate 6 to be processed to bend by rotating, and the end face of the other end and correspondence can compress plate 6 to be processed during bending.Certainly, in order to prevent because the other end and the end face of revolving part 3 depart from plate 6 to be processed, cause bending the problem that technique cannot complete, compressing structure can also be separately provided, compressing plate 6 to be processed, lower concrete structure is referred to scheme of the prior art, is not described in detail in this.
The specific works process rotating crimp mechanism that the present embodiment provides is:
During straight line driving mechanism 1 drives upper mold 2 descending, first it is that revolving part 3 contacts plate 6 to be processed.Straight line driving mechanism 1 drives upper mold 2 to continue traveling downwardly, and revolving part 3 starts to rotate in the strip groove of upper mold 2, drives plate 6 to be processed flexural deformation, shapes complete during to straight line driving mechanism 1 descending dead point.Subsequently, straight line driving mechanism 1 starts up, and revolving part 3 starts opposite direction in strip groove and rotates, until setting back.
Use the rotation crimp mechanism formation high-strength plate "Ji" type beam that the present embodiment provides, relatively conventional draw forming or binder shape defects such as causing part resilience is relatively big, sidewall curling, surface scratch, at first side, only there is plastic deformation in plate 6 to be processed, plate 6 to be processed does not has the flowing of material in forming process yet, feature side-wall will not produce the phenomenons such as curling, surface scratch, thus avoids the generation of defect in prior art.
Preferred as technique scheme, the bottom of upper mold 2 is also fixedly connected with guide 5, for guiding the rotation of revolving part 3.Guide 5, for limiting the rotation of revolving part 3, provides the support of horizontal direction for it.
Preferred as technique scheme, the cross sectional shape of guide 5 is trapezoidal, and in the rotary course of revolving part 3, the cambered surface of revolving part 3 contacts with the trapezoidal inclined plane of guide 5.
Preferred as technique scheme, the cross section central angle of revolving part 3 is 270 degree.This central angle angle especially suitable processing right angle plate.The sector crosssection center of circle angle of revolving part 3 can be arranged according to the bounce situations etc. of the practical situation of part and part, and to process a few type beams of different angles, maximum bend angle can reach 135 degree, it is possible to realizes negative angle and produces.This rotation crimp mechanism is possible not only to ensure the dimensional accuracy of part, surface quality, and can reduce operation.
Preferred as technique scheme, the angle on two surfaces that the first side of lower mold 4 is corresponding is predetermined angle, and described predetermined angle is less than or equal to 90 degree, to realize negative angle production.
Preferred as technique scheme, the first side of lower mold 4 is corresponding with the axial location of groove, thus corresponding with the axial location of revolving part 3, and the rotational angle of revolving part 3 is corresponding with the angle of bend of plate 6 to be processed, is conducive to controlling machining angle.
What the present embodiment provided rotate crimp mechanism relatively with 2 advantages of below existence that shape of "Ji" type beam in prior art:
1, the Forming Theory of part is different: it is all by making whole plate generation plastic deformation that traditional draw forming or binder shape, and plate has the flowing of material at die corner, causes the defects such as part resilience is relatively big, sidewall curling, surface scratch；The rotation crimp mechanism that the present embodiment provides simply makes part that plastic deformation occurs at the first side of lower mold, and plate does not has the flowing of material in forming process yet, thus avoids the generation of disadvantages described above.
2, its rotation angle range of revolving part rotating crimp mechanism is relatively big, and maximum can reach 135 degree, produces such that it is able to realize negative angle, decreases operation, reduce cost.Using traditional technique, need to increase operation, multistep realizes, relatively costly.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and replacement, these improve and replace and also should be regarded as protection domain of the present utility model.
