The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described.
In the square hole or irregularly-shaped hole in the middle of the expansion link 11 insertion telescopics 10, and be fixed into integral body with rivet, the two ends of expansion link connect into rotating one with an end of forward and backward two universal joints 9,12 with pin respectively, the other end of forward and backward universal joint is connected with the end of adjusting rod 15 and worm screw 8 respectively, constitutes dwang.
There are straight-tooth or tooth in the upper end of adjusting gear 3, there is external screw thread the lower end, and adjusting gear inserts in the casing 2, and connects into integral body with its lower end screw thread and casing 2, the through hole that adjusting rod 15 ends of dwang pass on frame 13 and the drive end bearing bracket 14 is fixed on the frame 13 with nut, is the stiff end of dwang.
In the laterally inserted casing 2 of worm screw 8 ends of dwang, and straight-tooth on worm screw 8 and the adjusting gear 3 or tooth engagement, the chassis of filling adjusting rod 1 its lower end of usefulness is screwed on the upper surface of casing 2, the upper end has outward flange, lower surface to be screwed the first piston 5 of pressing plate 7, cunning fits over inner surface to be had in the oil cylinder 4 of cascaded surface, oil cylinder is screwed on the lower surface of casing 2, and how many filling stroke regulating mechanisms are assembled into.
On have step-like second piston 6 of oil duct to be installed in the first piston 5, and join the executive item that constitutes how many fillings of secondary, as shown in Figure 1 and Figure 2 with first piston 5 inwalls and pressing plate 7 endoporus cunnings.
If will process the multilayer stampings, at first to regulate the stroke of how many fillings according to the requirement of converted products.With adjusting rod 15 ends on the instrument rotation dwang, make its rotation and pass through forward and backward universal joint 9,12, telescopic 10 drives worm screw 8 and rotates, rotate by adjusting gear 3 again by worm screw with worm screw 8 engagements, and adjusting gear axially moves up and down along casing 2, in how many filling stroke adjustment processes, oil cylinder 4, filling adjusting rod 1, first piston 5, casing 2 can not move.
