Abstract
The utility model belongs to the improvement of roughing mill bottom working roll compensating cylinder hydraulic pipeline structure, particularly a kind of roughing mill bottom working roll compensating cylinder hydraulic pipe line of improvement, comprise roughing mill bottom working roll compensating cylinder, the oil inlet and outlet of roughing mill bottom working roll compensating cylinder respectively connected the hard tube of long 250-350mm, hard tube is connected to flexible pipe by joint, flexible pipe is connected to manifold block by interface, and what pick out from manifold block is installed with stop valve respectively into and out of oil pipe.It is rational in infrastructure, easy to operate, can shorten roll changing time, the probability of damage caused to oil hydraulic cylinder and oil inlet pipe when reducing roll change, the reliability of raising equipment, ensures carrying out smoothly of production, but also can shorten the fault handling time for the treatment of fluid cylinder pressure hose coupling leakage of oil.
Description
Technical field
The utility model belongs to the roughing mill bottom working roll compensating cylinder hydraulic pipe line of the improvement, particularly a kind of improvement of steel rolling roughing mill bottom working roll compensating cylinder hydraulic pipeline structure.
Background technique
Roughing mill bottom working roll compensating cylinder oil inlet pipe connects at cylinder body upper flange, and when working, site space is extremely narrow, once occur that leakage cannot process, can only pull out back-up roll, at least used time 4-5 hour.Secondly before and after homonymy, oil hydraulic cylinder adopts hard tube to join oil, usually there is collision during onsite application or damage causing the leakage of oil of oil hydraulic cylinder flange stress deformation, oil-feed adopts rapid pipe joint again, usually damage because producers are not familiar with assembly and disassembly methods during onsite application, substantially all will damage one at every turn.Not only cause the wasting of resources, and incur loss through delay roll changing time.Also want artificial pressure release after removing oil inlet pipe during last each roll change, cause personnel hazard.
Model utility content
The purpose of this utility model is the roughing mill bottom working roll compensating cylinder hydraulic pipe line providing a kind of improvement, it is rational in infrastructure, easy to operate, roll changing time can be shortened, the probability of damage caused to oil hydraulic cylinder and oil inlet pipe when reducing roll change, the reliability of raising equipment, ensures carrying out smoothly of production, but also can shorten the fault handling time for the treatment of fluid cylinder pressure hose coupling leakage of oil.
The purpose of this utility model is achieved in that a kind of roughing mill bottom working roll compensating cylinder hydraulic pipe line of improvement, comprise roughing mill bottom working roll compensating cylinder, the oil inlet and outlet of roughing mill bottom working roll compensating cylinder respectively connected the hard tube of long 250-350 ㎜, hard tube is connected to flexible pipe by joint, flexible pipe is connected to manifold block by interface, and what pick out from manifold block is installed with stop valve respectively into and out of oil pipe.
Hydraulic pipe line of the present utility model sets up manifold block.Adopt threaded joint; Remove rapid pipe joint; Homonymy oil hydraulic cylinder adopts flexible pipe to connect.Oil hydraulic cylinder welds out one section of about 300mm hard tube, then soldered splice; Oil hydraulic cylinder joint and manifold block joint adopt flexible pipe to be connected.Hydraulic station oil inlet pipe installation high-voltage stop valve out, avoids removing misoperation oil spout after oil inlet pipe.In order to improve interchangeability, institute's employing joint only has two kinds, with finish rolling many stand use identical.
The good effect that the utility model produces:
After transformation, without the need to tearing the rear pressure release of pipe open, personnel zero security risk; Roll changing time obtains shortening about 30-60 minute, eliminates the dismounting pressure release work to rapid pipe joint.Once there is the leakage of oil of oil hydraulic cylinder hose coupling, deal with only need 20 minutes less than, greatly shorten time less than former 4-5.In addition without the need to removing pressure release after oil inlet pipe, avoid personnel's industrial injury.
The utility model is rational in infrastructure, easy to operate, shortens roll changing time, reducing roll change is the damage caused to oil hydraulic cylinder and oil inlet pipe, improve the reliability of equipment, ensured to produce and carried out smoothly, and shortened the processing time for the treatment of fluid cylinder pressure hose coupling oil leakage fault.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of roughing mill bottom working roll compensating cylinder hydraulic pipe line of improvement, as shown in Figure 1, comprise roughing mill bottom working roll compensating cylinder 1, the oil inlet and outlet of roughing mill bottom working roll compensating cylinder 1 respectively connected the hard tube 2 of long 250-350 ㎜, hard tube 2 is connected to flexible pipe 3 by joint, flexible pipe 3 is connected to manifold block 4 by interface, and what pick out from manifold block 4 is installed with stop valve 5 respectively into and out of oil pipe.What pick out from manifold block 4 is made up of into and out of oil pipe hard tube.Hard tube is made up of steel pipe or copper pipe.
