The utility model content
The purpose of this utility model provides a kind of separate type hydraulic tongs, makes its use more safe and reliable, can reliably locate between upper bolster and the caliper.
The utility model is achieved in that the separate type hydraulic tongs, comprise caliper, the caliper inner bottom part is provided with hydraulic cavities, be provided with piston in the hydraulic cavities, be positioned at piston on the caliper and be respectively equipped with the oily passage of turnover in both sides up and down, in the caliper with the coaxial die cavity that is provided with of piston, the piston rod that links to each other with piston upwards stretches in the die cavity from hydraulic cavities, be tightly connected between caliper and the piston rod, be symmetrically fixed with two pressing mold guide pillars in the die cavity, being respectively equipped with counterdie and patrix between the two pressing mold guide pillars, conflicts in the bottom of counterdie in the piston upper end, and the patrix top is provided with upper bolster, caliper top is provided with the projection to the upper bolster projection, upper bolster is provided with the depression that matches with projection, is provided with lockable mechanism between upper bolster and the arbitrary projection, and described lockable mechanism comprises horizontally disposed blind hole in the upper bolster, the upper bolster surface is provided with the chute of connecting the blind hole side, stage clip and latch are installed in the blind hole successively, and one handle wears chute and latch fixes, and the latch end is stretched in the jack that is provided with on the projection.
During the utility model work, two wire terminals are inserted in the aluminium hydraulic pressed connecting pipe, and aluminium hydraulic pressed connecting pipe placed between the upper die and lower die, when the oil-feed of piston bottom, piston stroking upward, the promotion counterdie moves upward, and under powerful action of hydraulic force, the working face between the upper die and lower die is crimped on aluminium hydraulic pressed connecting pipe and corresponding cable together; After crimping is finished, the oil-feed of piston top, piston is moved down, shed pressure on the upper bolster, pull handle along chute then, drive latch and jack and be separated, horizontal sliding upper bolster then, make between upper bolster and the caliper slide relative and be separated, patrix and aluminium hydraulic pressed connecting pipe can be separated from top and caliper, finish the crimping process; Because latch and jack location are reliable, make to be difficult between upper bolster and the caliper slide relative takes place, its use is more reliable.The utility model can be used for using as crimping tool in the interconnecting of wire terminal of overhead wire or underground cable.
Described pressing mold guide pillar section can semicircular in shape; Adopt semicircle pressing mold guide pillar can make upper die and lower die and pressing mold guide pillar no-float, close the position during upper and lower mould crimping accurately, be difficult for inclined to one side mould.
The interior lower edge of described projection is 55 ° of angles.This design can make between upper bolster and the caliper axial compressive force even, and matching part is not yielding, can not produce locking phenomenon between upper bolster and the caliper.Be convenient carrying and lifting, left-right symmetric is provided with portable on the described caliper.
