Detailed description of the invention
Below in conjunction with accompanying drawing, by the description to embodiment, the present invention will be further described:
As Fig. 1, 2, shown in 3, a kind of vertical ladder of the present invention protects cage tools, comprise base 1, base 1 welds a circular arc mould 2, inner side uniform welding 15 girth members 8 of circular arc mould 2, girth member 8 welds with base 1, the two ends of circular arc mould 2 are rotationally connected a rod member 3 respectively by the second turning cylinder 11, as Fig. 3, shown in 4, rod member 3 comprises bar handle 12 and shaft 13, the cross section of shaft 13 is groove-like, bar handle 12 is positioned at the groove of shaft 13, and the length of bar handle 12 is greater than the length of shaft 13, bar handle 12 and shaft 13 are all fixedly connected with the second turning cylinder 11, the side in the center of circle of the concave surface facing circular arc mould 2 place circle of shaft 13 groove, a spring 10 fixed by rod member 3 on bar handle 12, the other end of spring 10 is fixed on base 1 and is positioned at place inside rod member 3, base 1 installs first turning cylinder 4 at the circle centre position of circular arc mould 2 place circle, first turning cylinder 4 is vertical with base 1 and be rotationally connected with base 1, first turning cylinder 4 connects a connecting rod 6, the length of connecting rod 6 is greater than circular arc mould 2 place radius of a circle, connecting rod 6 welds a casting die 7 being positioned at circular arc mould 2 outside, base 1 fixedly mounts the first block 5 in the junction near circular arc mould 2 and a rod member 3, first block 5 is located at the outside of circular arc mould 2, base 1 is provided with the second block 14 being positioned at circular arc mould 2 outside, line between first block 5 with the second block 14 is parallel with the axis 16 of circular arc mould 2, and the distance between the first block 5 and the second block 14 is less than the length of rod member 3, base 1 is also provided with third gear block 15 at the other end, second block 14 is symmetrical relative to the axis 16 of circular arc mould 2 with third gear block 15, base 1 is fixed a baffle plate 9, baffle plate 9 is located at outside circular arc mould 2, and with the distance between the first block 5 and vertical ladder, to protect the length of straight flange of cage consistent, baffle plate 9 is positioned at the side that base 1 fixes the first block 5, line between baffle plate 9 and the first block 5 and the axis being parallel of rod member 3 when initial position.
Distance between casting die 7 of the present invention and circular arc mould 2 should protect the consistency of thickness of cage workpiece with vertical ladder, the first block 5 and the distance between circular arc mould 2 consistent with the distance between casting die 7 and circular arc mould 2.In addition, refer to inside rod member 3 of the present invention and be in the same side with the center of circle of circular arc mould 2 place circle relative to rod member 3 inside rod member 3.
One end that first vertical ladder is protected cage workpiece by the present invention is in use against on baffle plate 9, and the other end making vertical ladder protect cage workpiece is each passed through the gap between the first block 5 and circular arc mould 2 and the gap between casting die 7 and circular arc mould 2 around circular arc mould 2 lateral surface, then the rod member 3 being located at baffle plate 9 side is outwards rotated, rod member 3 is turned to against till the second block 14, complete and the vertical ladder between the first block 5 and baffle plate 9 is protected cage workpiece roll over straight flange, and then rotate the first turning cylinder 4, connecting rod 6 is made to drive casting die 7 to move in a circle, last another rod member 3 that rotates again is to against third gear block 15, complete the other end folding straight flange that vertical ladder protects cage workpiece, because the total length of vertical ladder workpiece remains unchanged, and the length of circular arc portion also remains unchanged, length of straight flange between first block 5 and baffle plate 9 also remains unchanged, therefore the length of straight flange of the other end also can remain unchanged, after completing flanging action, unclamp rod member 3, due to the elastic force effect of spring 10, original position got back to by rod member 3.
First turning cylinder 4 of the present invention and the second turning cylinder 11 are by axle center and axle sleeve composition.
Vertical ladder of the present invention protects the labour intensity that cage producing device reduces workman, improves the working (machining) efficiency that vertical ladder protects cage, and it is more attractive in appearance to make the vertical ladder made protect cage outward appearance.
Due under the drive of the first turning cylinder 4 after making connecting rod 6 turn to the other end from circular arc mould 2 near first block 5 one end, casting die 7 can substitute and be equivalent to the extruding barrier effect that the first block 5 pairs of vertical ladders protect cage workpiece, and at circular arc mould, block is set away from one end of the first block 5 and can blocks vertical ladder and protect cage workpiece and paste and circular arc mould 2, therefore do not need to arrange again the block with the first block 5 symmetry at this place.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
