Abstract
The utility model provides a collapsible hydraulic cylinder which is a built-in wound roll of a recoiling machine and is a requisite mechanical device for reeling band steel into a coiled material in the metallurgy industry. The collapsible hydraulic cylinder consists of a collapsible hydraulic cylinder, a wound roll shaft, four sector plates, a tension rod and four collapsible sliding blocks. The structure is as follows: the collapsible hydraulic cylinder is a collapsible hydraulic cavity body which is processed from the tail part of the wound roll shaft, a piston is arranged inside the cavity body to form the collapsible hydraulic cylinder; the extending part of the piston is connected with the tension rod, the outside part of the tension rod is provided with the wound roll shaft, the outside part of the wound roll shaft is provided with four sector plates; the collapsible sliding blocks are arranged between the wound roll shaft and the sector plates. When the collapsible hydraulic cylinder works, the piston drives the tension rod, the other end of the tension rod drives the four collapsible sliding blocks to move axially, while the collapsible sliding blocks jack up the sector plates 2 to form a whole circle. The collapsible hydraulic cylinder has the characteristics of novel and compact as well as simple structure, good dynamic balancing performance and great stiffness, etc., thereby belonging to a novel collapsible hydraulic cylinder which is a built-in wound roll of a recoiling machine integrating economical efficiency and practicability into a whole.
Description
Technical field
Harmomegathus hydraulic cylinder described in the utility model is that embedded coiler mandrel is that metallurgy industry becomes strip coiling coiled material and sets up tension force with milling train, realizes the complete indispensable metallurgical machinery equipment of the technological requirement of endless rolling continuously.
Background technology
The version of conventional spool is the afterbody that the harmomegathus hydraulic cylinder is put together on reel separately by bolt at present, the spool piece of this kind structure is more, and is influential to the dynamic balance performance of reel, the long arrangement space that influences main transmission of reel length, reel weight is big, increases rotary inertia.Two reel swinging coiling machines are used in the cold rolling unit of high-speed and continuous, it is little to require its compact conformation to take up room, reel wants the stiffness large rotating inertia little, dynamic balance is good, at existing problem in the above-mentioned prior art, a kind of novel harmomegathus hydraulic cylinder of research and design is embedded coiler mandrel, and existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is that a kind of novel harmomegathus hydraulic cylinder of research and design is embedded coiler mandrel, thereby solves problems such as present existing reel weight is big, dynamic balance performance difference.Harmomegathus hydraulic cylinder described in the utility model by embedded coiler mandrel by harmomegathus hydraulic cylinder, spool shaft, fan template, pull bar, harmomegathus slide block, formed.Its structure is that the harmomegathus hydraulic cylinder is that the spool shaft afterbody is processed into harmomegathus hydraulic cylinder cavity, and piston is installed in and forms the harmomegathus hydraulic cylinder in the cavity.The extension of piston is connected with pull bar, and the outside of pull bar is a spool shaft, and four fan templates are equipped with in the spool shaft outside.Between spool shaft and the fan template harmomegathus slide block is housed.
Two reel swinging coiling machines are used in the cold rolling unit of high-speed and continuous, and it is little to require its compact conformation of reel to take up room, and reel wants the stiffness large rotating inertia little, and dynamic balance performance is good.Harmomegathus hydraulic cylinder described in the utility model is embedded coiler mandrel, and the harmomegathus hydraulic cylinder is embedded spool shaft inside, has shortened reel length, has alleviated reel weight.Really it is little to belong to the stiffness large rotating inertia, the reel that dynamic balance is good.
When harmomegathus hydraulic cylinder described in the utility model was the work of embedded coiler mandrel, because pull bar one end at reel center is connected with the piston of reel harmomegathus hydraulic cylinder, the piston drive pull bar of harmomegathus hydraulic cylinder moved axially.The crosshead that is fixed on the pull bar other end simultaneously drives four harmomegathus slide blocks and moves axially, and moving of harmomegathus slide block then makes harmomegathus slide block contacted fanning strip jack-up with it, and four fanning strips can radial displacement under the effect of harmomegathus slide block, makes the reel footpath of rising.Four fanning strips constitute a full circle at the end face of harmomegathus slide block when rising by the footpath
The utlity model has that novel structure, structure are compact simple more, dynamic balance is good, stiffness is big, dependable performance, satisfy advantage such as tandem mills technological requirement, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
Description of drawings
The utility model has two accompanying drawings, wherein
Accompanying drawing: 1, the harmomegathus hydraulic cylinder is the cutaway view that embedded coiler mandrel associated components assembles
Accompanying drawing: 2, the harmomegathus hydraulic cylinder is embedded coiler mandrel cutaway view
Among the figure: 1, spool shaft 2, fan template 3, spindle nose 4, pull bar 5, piston 6, swivel joint 7, harmomegathus slide block 8, bearing 9, gear
The specific embodiment
Specific embodiment of the utility model is made up of harmomegathus hydraulic cylinder, spool shaft 1, fan template 2, pull bar 4, harmomegathus slide block 7, institute as shown in drawings.Its structure is that the harmomegathus hydraulic cylinder is that the spool shaft afterbody is processed into harmomegathus cylinder cavity, and piston 5 is installed in and forms the harmomegathus hydraulic cylinder in the cavity.The extension of piston 5 is connected with pull bar 4, and the outside of pull bar 4 is spool shaft 1, and four fan templates 2 are equipped with in spool shaft 1 outside.Between spool shaft 1 and the fan template 2 harmomegathus slide block 7 is housed.
The utility model has omitted traditional isolated harmomegathus hydraulic cylinder, the spool shaft afterbody is processed into harmomegathus hydraulic cylinder cavity, piston is installed and is formed the harmomegathus hydraulic cylinder in the cavity, thereby shortened reel length greatly, alleviated reel weight, reduced number of spare parts, improve the dynamic balance of reel, reduced rotary inertia.Be installed in reel in the bearing block of dissection type revolving body by bearing 8 during use, and be fixed on the revolving body by end cap in the end, gear wheel 9 on the reel meshes with its travelling gear respectively, thereby realizes that reel can rotate simultaneously with revolving body, again can rotation.Pull bar 4 one ends at reel center were connected with reel harmomegathus hydraulic cylinder when reel rose by the footpath, and the harmomegathus hydraulic cylinder drives pull bar and moves axially.The crosshead that is fixed on the pull bar other end simultaneously drives four harmomegathus slide blocks 7 and moves axially, moving of harmomegathus slide block 7 then makes harmomegathus slide block 7 contacted fanning strip 2 jack-up with it, four fanning strips 2 can radial displacement under the effect of harmomegathus slide block 7, makes the reel footpath of rising.Four fanning strips 2 constitute a full circle at the end face of harmomegathus slide block 7 when rising by the footpath, can not produce impression when therefore batching thin strip.The harmomegathus hydraulic cylinder is by swivel joint 6 fuel feeding.
