Description
Technical field
The present invention relates to a kind of steel wire rope stranding machine, relate in particular to a kind of pipe free steel wire rope stranding machine.Belong to machinery manufacturing technology field.
Background technology
Along with deepening constantly of reform and opening-up process, market economy is growing, has started the new situation of China's Steel Wire Products Industry innovation and development.Since China's highway, high-speed railway, the machinery manufacturing industry especially development drive of auto manufacturing makes the steel cord, the PC goods, and the product of the metallic articles such as Wire Rope for Important Use, welding wire, spring steel wire is with the speed development of national GDP twice.The output of China's wire rod metallic article in 2011 has reached 1,955 ten thousand tons according to statistics.China's Steel Wire Products Industry has been established the status of world metallic article big country.Wherein steel wire rope and goods thereof more relate to the necessary product of each department of national economy.
Steel wire rope is various in style, and complex structure is various.But mainly be equipped for tubular stranding machine and rope-forming machine.Traditional tubular stranding machine: by rotary barrel (built-in Loosen up wire wheel and the canoe of controlling with laying tension), gear exchange gearbox, traction wheel and gear, with the I-beam wheel finished product admission machine of wire-arranging mechanism, the various pieces such as Universal electric control form.In the rotary barrel, general vertical row are built-in 3 I-beam wheel unwrapping wire canoes evenly.Because the structure of strand wire is different, 2 rotary barrel tandem dockings form such as 1 * 7 needs, and 1 * 19 then 6 cylindrical shell tandem dockings of needs are that have even more longer with length.
Existing tubular stranding machine has following feature and needs the break-through point of reform and innovation:
1, the vertical row series connection of a plurality of rotary bodies with the unwrapping wire canoe, machine construction is complicated, and the axiality of general assembly and installation and the requirement of levelness are high;
2, the rotary inertia of rotary body is large, and rotative power consumption is large, and rotating speed is subjected to the restriction of structure, and production capacity is lower, forms the huge phenomenon of similar machine quantity;
3, the lay pitch of strander is that rotating speed and draught line speed by rotary barrel forms.Therefore the gear lay pitch case of three three gears of the essential configuration of machine or four three gears drives traction wheel, and the level that has been adjusted to of the lay pitch changes, and excursion is little;
4, each unwrapping wire canoe steel wire of tubular stranding machine finally compiles at the matched moulds place at rotary barrel outer threading mouth, and canoe floats on the rotary barrel axis, does not allow rotation.But because forming canoe, operation or equipment jam rotate with rotary barrel.Then can cause the tendency to drift away of drum or I-shaped wheel shaft and fly out, cause great personal injury accident;
5, the rotary barrel window is many, causes noise, affects environment.
