Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is explained.
Embodiment 1: as accompanying drawing 1,2, the general seaming tool of a kind of self-locking nut self-centering, comprise adjustment screw 1, pressing plate 2, top board 3, front side board 4, back side panel 4.1, top die 5 and dip mold 5.1, its pressing plate 2 gives top die 5 stamping press through the rectangular opening on top board 3; Pressing plate 2 top connects power source, and bottom is forked type.Adjustment screw 1 is through screwed hole adjustment top die 5 height of top board 3, and top die 5 is also provided with the elastic supporting member for supporting optical member (not shown in FIG.) being supported in side plate or dip mold 5.1, and turn adjustment screw 1 can make the relative top board 3 of top die 5 move up and down distance.Front side board 4 and back side panel 4.1 clamp top die 5 and dip mold 5.1, are provided with the hand-hole of processing parts in the middle part of front side board 4; Nut fixed head 7 is provided with, for fixing processing parts outside hole.
As Fig. 3,5,6, the die face of described top die 5 and dip mold 5.1 is equipped with the vertical equilateral right angle trigonometry v notch v of high line, and upper and lower mould is symmetrical.The closing in seat 6 be made up of seat ring 6.1, closing in block 6.2, spring 6.3 and forming blocks 6.4 is vertically placed with between die face breach; Described closing in block 6.2 in bar shaped, along seat ring 6.1 radially across seat ring 6.1, overlap between its outer end and seat ring 6.1 and have spring 6.3, the inner is provided with forming blocks 6.4; Be connected to closing in block 6.2 one end to described forming blocks 6.4 plug-in type, and locked by trip bolt 8; Forming blocks 6.4 can be rectangle, ellipse or thimble shape closing in forming blocks.Described closing in block 6.2 is four, the outer end of its relative seat ring 6.1 and top die 5 and dip mold 5.1 die face breach perpendicular contact.Seat ring 6.1 is fixed on front side board 4 or back side panel 4 actively, only needs to move up and down, can not left and right or movable, and by the fixing hole on seat ring 6.1, screw, the bar-shaped trough on side plate can realize (not shown in FIG.).
Downward stamping press is passed to top die 5 by top board 3, top die 5 moves down, two vertically lack limit transmits the vertical closing in power lacking limit to closing in block 6.2, this closing in power points to the center of seat ring 6.1, closing in block 6.2 Compress Spring 6.3, further insertion seat ring 6.1, moves along die face to die face right-angled apices simultaneously.In this process, closing in block 6.2 lacks limit perpendicular to the vertical of die face all the time, and four closing in blocks 6.2 compress to the center of seat ring 6.1, make the forming blocks 6.4 compression process part of closing in block 6.2 front end shaping.
Embodiment 2: as Fig. 4, the breach of above-mentioned top die 5 and dip mold 5.1 is the vertical circular arc of high line; Described closing in block 6.2 is three to six, and the vertical axis axial symmetry arrangement of its relative top die 5 and dip mold 5.1, its closing in process is similar to embodiment 1.It is slightly elliptic arc that the circular arc of die face breach needs according to the scope of workpiece, and top die 5 moves up and down in process, closing in block 6.2 Compress Spring 6.3, inserts seat ring 6.1 further, apicad moves along circular arc die face simultaneously.In this process, closing in block 6.2 is basically perpendicular to die face, and when closing in block 6.2 is three, five, six, some is on the high line of arc die face, and closing in block 6.2 compresses to the center of seat ring 6.1, makes the forming blocks 6.4 compression process part of closing in block 6.2 front end shaping.
Arc die face moves up and down in process, the closing in block 6.2 of arc die face height line side is subject to the holding power of arc die face can not point to seat ring 6.1 central point (but angle is very little) completely, but the processing effect that closes up more flexibly can be obtained, increase arc die face width and stressed angle can be made to ignore.
When closing in block 6.2 is four, the stamping press of every bar closing in block 6.2 pairs of nuts is completely equal, can obtain best closing in precision; When closing in block 6.2 is not four, the stroke near the closing in block 6.2 of the high line of arc die face is more bigger, now needs to change closing in block 6.2, makes the closing in block 6.2 the closer to arc die face height line need shorter, can obtain the effect that closes up accurately.
