Abstract
The utility model discloses a kind of support rollers in hot continuous rolling technical field to be lifted cylinder, mainly includes oil sealing, transparent cover, piston rod, gland, oil circuit, buffer bar, cylinder body.The utility model mainly passes through end middle part on the piston rod and adds buffer bar, transparent cover, using the connection installation of round sphere contact level between the lower end and piston rod of buffer bar.Using be avoided that after the utility model because support roller decline during it is asynchronous cause to caused by the oblique impact of piston rod piston rods bend deformation, oil sealing damage the problem of, can preferably improve support roller lifting cylinder job stability and increase its online service life.
Description
Technical field
The utility model relates to a kind of improved support rollers to be lifted cylinder.
Background technique
After the support roller lifting cylinder being applied in the prior art by the support roller of oblique whereabouts there is being hit, frequently occur
The problem of piston rods bend deformation, oil sealing are damaged, online service life cannot be guaranteed well.
Summary of the invention
The purpose of the utility model is to provide a kind of improved support rollers to be lifted cylinder, can solve above-mentioned branch in the prior art
Bending deformation, the problem that oil sealing is damaged, service life is short after support roller lifting cylinder piston rod is frequently hit.
A kind of improved support roller of the utility model is lifted cylinder, is mainly made of rack, cylinder body, piston rod, transparent cover, living
The cylindrical cavity of the upper center of stopper rod is provided with buffer bar, is also equipped with gland by bolt in the upper end of transparent cover, buffer bar
The structure installation being coincide between bottom and piston rod using spherical surface.
Using such structure, because using mechanical plug-in mounting structure between buffer bar and piston rod.When support roller is oblique
Buffer bar can weaken that part is oblique to be acted under the action of mechanical clearance when to the buffer bar top for falling to piston rod upper end
Impact potential energy on piston rod, so that the oblique punching of piston rod be made effectively to be reduced by potential energy.Directly avoid piston rod
Directly by the problem for being knocked bending, oil sealing breakage after greater impact power.Again because being used between piston rod and buffer bar
The connecting installation structure of arc surface can preferably make buffer bar opposing pistons bar expand its surplus to swing.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the main view partial structural diagram of the utility model.
Specific embodiment
As shown in Figure 1, the improved support roller of the utility model is lifted cylinder, mainly by rack 8, cylinder body 9, piston rod 6, thoroughly
Lid 5 forms.The cylindrical cavity of the upper center of piston rod 6 is provided with buffer bar 4, is also equipped in the upper end of transparent cover 5 by bolt 2
Gland 3.The structure installation being coincide between the bottom and piston rod 6 of buffer bar 4 using spherical surface.
As shown in Figure 1, cylinder body 9 is mounted in rack 8 when manufacture and use the utility model.Gland 3 and buffer bar 4
Between be preferably also equipped with oil sealing 1 or dustband.Oil circuit 7 is connected by cylinder body 9, rack 8 and oil pipe.
