The specific embodiment:
Further specify the particular content of the present invention and the course of work below in conjunction with the accompanying drawing illustrated embodiment.
Use the multi-point formation apparatus of oscillating head unit to compare with other multi-point formation apparatus, main difference is that its element body unit has the yaw function.Fig. 1 adopts polyurethane cover 1 to be the oscillating head unit schematic diagram of flexible member, mainly is made up of polyurethane cover 1, yaw dish 2, steel ball 3 and supporting seat 4; Polyurethane overlaps 1 head and yaw dish 2 end faces all adopt planar structure; Polyurethane cover 1 is locked by self structure with supporting seat 4; The annular groove structure is processed at the locking position of polyurethane cover 1, and this structure makes that polyurethane cover 1 locking position elasticity is better, assembles up to be more prone to.The difference of Fig. 2 and Fig. 1 is that polyurethane cover 1 is locked by buckle jump ring 5 with supporting seat 4; Two in buckle jump ring one cover is locked mutually by hook formation, consults shown in Fig. 3 and 4; This locking mode can be more firm connection polyurethane cover 1 and supporting seat 4; Adopt the locking mode of buckle jump ring 5 to be applicable to that various employing polyurethane are the oscillating head unit of flexible member.Polyurethane overlaps 1 head and yaw dish 2 end faces all adopt spherical structure among Fig. 5; The solid circle structure is adopted at the locking position of polyurethane cover 1, and the elasticity of this structure is poor slightly, assembles up slightly and has any problem, but make polyurethane cover 1 connect more firm with supporting seat 4 after the assembling.Certainly, the annular groove structure also can be adopted in the locking position of polyurethane cover 1.Polyurethane cover 1 has adopted structure with holes among Fig. 6, has 7 rounds, and this structure can significantly increase the retractility of polyurethane cover 1, improves the yaw effect of oscillating head unit.Row's number in hole is many more in actual applications, and the retractility of polyurethane cover 1 is good more, and the yaw effect of oscillating head unit is good more.Polyurethane overlaps 1 head and yaw dish 2 end faces can adopt planar structure, also can adopt spherical structure.Polyurethane cover 1 adopts ripple struction among Fig. 7, and the ripple number is 4, and its effect also is the retractility that increases polyurethane cover 1, improves the yaw effect of oscillating head unit.The ripple number is many more in actual applications, and the retractility of polyurethane cover 1 is good more, and the yaw effect of oscillating head unit is good more; Polyurethane overlaps 1 head and yaw dish 2 end faces have adopted spherical structure, also can adopt planar structure.Fig. 8 adopts helical spring 6 to be the oscillating head unit schematic diagram of flexible member, mainly is made up of yaw dish 2, steel ball 3, supporting seat 4 and helical spring 6; Yaw dish 2 end faces adopt spherical structure, also can adopt planar structure; Helical spring 6 and yaw dish 2 and supporting seat 4 connect by self structure.To be helical spring 6 adopt buckle jump rings 5 to connect with yaw dish 2 and helical spring 6 and supporting seat 4 for Fig. 9 and the difference of Fig. 8.Helical spring 6 adopts the structure of end band grabs among Figure 10, and in the boring of the relevant position of yaw dish 2 and supporting seat 4, and its effect is better to realize connecting of helical spring 6 and yaw dish 2 and supporting seat 4; Band grab helical spring 6 is consulted shown in Figure 11; Yaw dish 2 end faces adopt planar structure, also can adopt spherical structure.
Each oscillating head unit all needs to connect with lead 7, thereby realizes moving up and down of oscillating head unit.Oscillating head unit connects with lead 7 by supporting seat 4.Supporting seat 4 adopts snap ring 8 to connect with lead 7 among Figure 12.Supporting seat 4 is to adopt thread connection with lead 7 among Figure 13.Supporting seat 4 adopts straight pin 9 to connect with lead 7 among Figure 14.
The course of work when illustrating the multi-point formation apparatus shaping plate accessory that uses oscillating head unit below.At first, the element body group that will have a yaw function by guiding mechanism is adjusted into needed shape face; Then, by load maintainer processed plate accessory is loaded, sheet material contacts with the element body unit with yaw function in loading procedure, because oscillating head unit can be to space any direction swing, so thereby any one oscillating head unit all can adapt to the deformation tendency of sheet material to carry out yaw and keeps contacting with the large-area of sheet material; At last, workpiece is also taken out in unloading, each oscillating head unit homing again under the effect of flexible member.
With Fig. 7 is the course of work that example illustrates single oscillating head unit.Sheet material contacts with oscillating head unit under certain pressure, and the distortion meeting of sheet material produces active force to oscillating head unit, and this active force can act on polyurethane and overlap on 1 head and the yaw dish 2.Because polyurethane cover 1 has retractility, can make yaw dish 2 have the free degree of any direction at the sphere of the containing lower edge steel ball 3 of polyurethane cover 1, corresponding opposite side ripple shortens so sheet deformation can make polyurethane overlap the ripple elongation of 1 one sides to the active force of oscillating head unit, thereby yaw dish 2 is rotated to adapt to the distortion of sheet material.After be shaped finishing unloading, oscillating head unit no longer is subjected to the active force of sheet material, will overlap homing under 1 the elastic reaction at polyurethane.
Use the multi-point formation apparatus of oscillating head unit to increase the contact area of element body unit and sheet material, and can adapt to the deformation tendency of sheet material, thereby reduce impression and generation of defects such as wrinkling in the forming process significantly, the forming quality of raising workpiece.
