Abstract
The invention provides a kind of method of post oil pressure Oil cylinder drive end bearing bracket of quick-replaceable four sealing, by with the use of two kinds of instruments of jack and bottle gouard moved by hands, the piston rod of oil cylinder and moved cross beam are disengaged, then fix moved cross beam, with regard to the sealing of oil cylinder drive end bearing bracket can be changed.The method that this partial disassembly changes sealing, dismounting step only need 6 steps, change Sealing period 2.5 hours, solve the problems, such as that replacing Sealing period is long, labor intensity is big, safety coefficient is low.
Description
Technical field
The present invention relates to a kind of hydraulic press part exchanging method, especially a kind of post oil pressure Oil cylinder front end of quick-replaceable four
The method for covering sealing.
Background technology
At present, technical staff when changing four post hydraulic press cylinder seals, it is necessary to its upper side all be disintegrated, oil cylinder turns over
Turning 180 ° of drive end bearing brackets can complete upward, change Sealing period 20 hours or so.Existence time is long, efficiency is low, security is poor
The problem of.
The content of the invention
It is an object of the invention to provide a kind of method of post oil pressure Oil cylinder drive end bearing bracket of quick-replaceable four sealing, can solve the problem that
Change the problem of sealing of oil cylinder drive end bearing bracket is difficult.
In order to solve the above-mentioned technical problem, technical scheme is as follows:A kind of post oil pressure Oil cylinder of quick-replaceable four
The method of drive end bearing bracket sealing, its step are as follows：The moved cross beam of hydraulic press is first withstood with the whole strokes of jack stretching, is torn open
After laying down the bolt in terminal pad, jack declines 80mm, and moved cross beam is allowed to decline 80mm, the left-handed terminal pad of part 3
Fall on the moved cross beam of part 2；Then, hydraulic press is started, makes the piston rod backhaul 400mm of hydraulic press, channel-section steel is placed on work
Stopper rod lower end, then novel sealing opening upwards are placed on channel-section steel, then piston rod is withstood with a jack, close hydraulic press；
Then, drive end bearing bracket platen bolt is dismantled, drive end bearing bracket platen is held with two bottle gouards moved by hands when being left two bolts, dismounting is remaining
Two bolts, slowly loosen bottle gouard moved by hands and drive drive end bearing bracket platen to decline 300mm, now exposed drive end bearing bracket, unclamp first
Jack decline 200mm drive drive end bearing bracket decline 200mm simultaneously slide on drive end bearing bracket platen, then loosen two chain blocks until
Drive end bearing bracket and drive end bearing bracket platen are all fallen on channel-section steel, finally, the sealing of drive end bearing bracket damage are taken out, before new be sealingly mounted to
On end cap, complete to change sealing；When installing new sealing, carrying out operation according to inverted order can complete.
Improvement to above-mentioned technical proposal：The length of the channel-section steel is more than 500mm.
Beneficial effect：
The method of the post oil pressure Oil cylinder drive end bearing bracket of quick-replaceable four sealing of the present invention, by with the use of jack
With two kinds of instruments of bottle gouard moved by hands, the piston rod of oil cylinder and moved cross beam are disengaged, moved cross beam is then fixed, with regard to oil cylinder can be changed
Drive end bearing bracket seals.The method that this partial disassembly changes sealing, dismounting step only need 6 steps, it is small to change Sealing period 2.5
When, solve the problems, such as that replacing Sealing period is long, labor intensity is big, safety coefficient is low.
Brief description of the drawings
Fig. 1 is the structural representation of hydraulic press.
Fig. 2 is the structural representation after hydraulic press starts.
Fig. 3 is the structural representation of hydraulic press after replacing sealing.
Embodiment
By the following specific examples further illustrate the invention.
Hydraulic press structure chart as shown in Figure 1.The jack of elder generation's appliance 1 when changing cylinder seal（20 tons）Stretch out whole stroke tops
The firmly moved cross beam of part 2, the jack of bolt consequent 1 disassembled in the terminal pad of part 3 decline 80mm, and the moved cross beam of part 2 is with decline
80mm.The left-handed terminal pad of part 3 is allowed to drop on the moved cross beam of part 2.
As shown in Figure 2：Equipment is started, makes the piston rod backhaul 400mm of part 4, by the channel-section steel of part 10（Length is more than 500mm）Place
In the piston-rod lower end of part 4, the novel sealing of part 9（Opening upwards）It is placed on the channel-section steel of part 10, the jack of part 11（5 tons）Part 4 is withstood to live
Stopper rod, pass hull closure.The drive end bearing bracket platen bolt of demolition part 6, it is left the bottle gouard moved by hands of appliance 12 during 2 bolts（2）Before holding part 6
End cap platen, remaining 2 bolts are dismantled, slowly loosen the drive end bearing bracket platen of 12 bottle gouard moved by hands drivening piece of part 6 and decline 300mm, this
When exposed the drive end bearing bracket of part 8.The jack of unlocking element 1 declines the drive end bearing bracket of 200mm drivening pieces 8 and declines 200mm and slide in the front end of part 6
On lid platen.
As shown in Figure 3：Loosen the chain block of part 12（2）Until the drive end bearing bracket of part 8 and the drive end bearing bracket platen of part 6 all fall on part
On 10 channel-section steels, the damage sealing of the drive end bearing bracket of removal piece 8, the novel sealing of part 9 is installed on the drive end bearing bracket of part 8, completes to change sealing.Installation
When, carrying out operation according to inverted order can complete.
Claims (2)
1. a kind of method of the post oil pressure Oil cylinder drive end bearing bracket of quick-replaceable four sealing, its step are as follows：First stretched with a jack
Go out the moved cross beam that whole strokes withstand hydraulic press, after disassembling the bolt in terminal pad, jack declines 80mm, moved cross beam
With 80mm is declined, left-handed terminal pad is allowed to drop on moved cross beam；Then, hydraulic press is started, makes the piston of hydraulic press
Bar backhaul 400mm, channel-section steel is placed on piston-rod lower end, then novel sealing opening upwards are placed on channel-section steel, then with one thousand
