Description
Technical field
The utility model relates to a kind of Wire Rope Production instrument, particularly the two adjustable type independent wire strand pre-former of a kind of elevator.
Background technology
Independent wire strand is by the steel wire rope of multiply strand twisting.Because the internal stress of per share strand is not quite similar, the steel wire rope after being shaped is made to be loose shape.Easily there is the problem making steel wire broken end place nose because of steel wire fracture of wire in the steel wire rope in loose shape, thus cause damage to its pulley depended on or cylinder in the use of reality, affects the security of operation of elevator.
Pre-former manufactures the indispensable important tool part of preformed wire rope, and it can make strand carry out the elimination of stress at Cheng Shengqian, thus obtain longer work limitation, avoids the damage to pulley or cylinder.
Existing pre-former is formed primarily of front fixed disk, rear fixed disk and intermediate regulations dish, when in use according to steel cord structure, tensile strength of wire, by technological parameter requirement, front fixed disk and the distance of rear fixed disk and the drafts of intermediate regulations dish are adjusted, steel wire is passed through in the made race in each dish side, it is curved that each stock steel wire forms by technological parameter the spiral conformed to the lay pitch under the effect of 3 dishes, the strand forming spiral curved is twisted into steel wire rope again, thus obtains not loose steel wire rope.
But, current pre-former is single adjustable type pre-former, this pre-former can only be accomplished to make steel wire rope be not loose shape to the distortion of outer strands, and internal layer strand is not through predeformation so in loose condition (of surface), although the independent wire strand that the outer strands of the internal layer strand of loose condition (of surface) and not loose condition (of surface) is twisted into some extent solves the problem of fracture of wire, but when long-time use, its problem still there will be.
Summary of the invention

And the internal layer strand wheel on described front fixed disk and rear fixed disk is all positioned at the front of outer layer strand rope sheave.
And the position of corresponding adjustable pin hole is provided with and aligns mark on described front adjustment disk and rear adjustment disk.
And be all shaped with screw thread on the inwall of described pin ends and adjustable pin hole, the screw thread in the screw thread on pin and adjustable pin hole matches.
Advantage of the present utility model and beneficial effect are:
1. the two adjustable type independent wire strand pre-former of this elevator, during work, is arranged on this pre-former on the axle of twisting wire rope machine by centre bore.Then from the pin hole rear fixed disk, pin is wherein taken out, adjustment disk after rotating, by technological parameter, the pin hole on rear fixed disk and corresponding adjustable pin hole are aligned, then plug pin and give locked fixing, complete the setting of the latter half of strand deformation path of pre-former; Pin is taken out in the pin hole of the past fixed disk, adjustment disk before rotating, by technological parameter, the adjustable pin hole that the pin hole on front fixed disk is corresponding on front adjustment disk is aligned, then plug pin locked fixing, complete the setting of pre-former first half strand deformation path.Finally outer strands is placed on path that outer layer strand rope sheave formed, internal layer strand being placed in internal layer strand takes turns on the path that formed, it is curved that each waney strand forms different spirals under the traction of front machine, then outer strands and all not loose independent wire strand of internal layer strand is formed through once parallel twisting, improve the fatigue life of this kind of independent wire strand, extend its Use Limitation and reach 20%.
2. the two adjustable type independent wire strand pre-former of this elevator, is arranged by the position of adjustable pin hole corresponding on front adjustment disk and rear adjustment disk and aligns mark, facilitates the setting of deformation path under various criterion, increases work efficiency.
3. the two adjustable type independent wire strand pre-former of this elevator, adjustable pin designs is had at the forward and backward Fang Jun of pre-former, pin can play fixation to front adjustment disk and rear adjustment disk, when this pre-former is worked on production equipment, pin can not be made because of the vibrations of production equipment to occur the phenomenon loosening and exit, thus make this product can obtain stable technological parameter all the time.
4. the utility model scientific structure design is reasonable, has the advantage improving Fatigue Life of Steel Wire Rope, extend steel wire rope Use Limitation, constant product quality, is a kind of two adjustable type independent wire strand pre-former of elevator with higher innovation.
