Abstract
A kind of rotary pivot apparatus of memorial archway rolling mill guiding, belong to the rolling technical field of metal, its technical scheme is, it comprises pivot mount, pivot body, pivot barrel and oil cylinder, and described pivot body is vertically fixed in pivot mount, and described pivot barrel is enclosed within pivot body exterior, its upper end seals, lower end is pressed in pivot mount, and described oil cylinder is vertically fixed on the top of pivot barrel, and the lower end of its piston rod to reach in pivot barrel and corresponding with the upper end of pivot body.The utility model utilizes the thrust of oil cylinder by pivot barrel jack-up, because oil cylinder does not exist corrosion problem, substantially increases the reliability of rotary pivot apparatus.Present arrangement avoids the problem that in traditional guide and guard rotary pivot apparatus, bolt easily lost efficacy because of corrosion, change roll for memorial archway milling train and to provide convenience condition.The utility model structure is simple, easy to operate, reliable operation, effectively can reduce the labour intensity of workman, improves the operating efficiency changing roll.
Description
Technical field
The utility model relates to a kind of guide and guard rotary pivot apparatus of memorial archway milling train high reliability, belongs to the rolling technical field of metal.
Background technology
The rotary pivot apparatus of memorial archway rolling mill guiding, except for supporting except guide and guard, when carrying out roll change operation, can also allow guide and guard to rotate to an angle, mill housing being shifted out smoothly, so that when not dismantling guide and guard, realizing the quick-replaceable of roll.The rotary pivot apparatus of tradition memorial archway rolling mill guiding as shown in Figure 1, it forms primarily of pivot mount, pivot body, pivot barrel and bolt, pivot body is vertically fixed in pivot mount, pivot barrel is enclosed within pivot body exterior, its upper end seals, lower end is pressed in pivot mount, and bolt screws in the vertical screwed hole at pivot barrel top, and guide and guard are fixed on the side of pivot barrel.When roll changed by needs, be rotated down bolt with spanner, bolt continues to rotate after withstanding pivot body, by pivot barrel jack-up, the lower end of pivot barrel is thoroughly separated with pivot mount, then rotating hinge sleeve and with the guide and guard be connected, mill housing can be shifted out.Working environment residing for rotary pivot apparatus is very severe, and there is a large amount of water, iron scale, wet goods pollutant, bolt usually cannot rotate because of corrosion, causes very large difficulty to the replacing of roll.In addition, because bolt seal effect is poor, impurity is easy to enter pivot barrel inside, the rotational resistance of pivot barrel is increased, therefore many people can only be leaned on to rotate guide and guard by force when changing roll, not only increase the labour intensity of workman, and roll changing time often reaches a few hours, greatly reduce production efficiency.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of memorial archway rolling mill guiding rotary pivot apparatus of high reliability, thoroughly solves traditional guide and guard rotary pivot apparatus loses proper function problem because of bolt corrosion.
Problem described in the utility model realizes with following technical proposals:
A kind of rotary pivot apparatus of memorial archway rolling mill guiding, formation comprises pivot mount, pivot body, pivot barrel and oil cylinder, described pivot body is vertically fixed in pivot mount, described pivot barrel is enclosed within pivot body exterior, its upper end seals, lower end is pressed in pivot mount, and described oil cylinder is vertically fixed on the top of pivot barrel, and the lower end of its piston rod to reach in pivot barrel and corresponding with the upper end of pivot body.
The rotary pivot apparatus of above-mentioned memorial archway rolling mill guiding, also comprises manual pump in formation, and the oil-out of described manual pump is connected with the hydraulic oil interface of oil cylinder by high-pressure oil pipe.
The rotary pivot apparatus of above-mentioned memorial archway rolling mill guiding, described oil cylinder is connected with the top of pivot barrel by flange, is provided with sealing gasket between described flange and pivot barrel.
The rotary pivot apparatus of above-mentioned memorial archway rolling mill guiding, the lower end of the piston rod of described oil cylinder is provided with pressure bearing.
The rotary pivot apparatus of above-mentioned memorial archway rolling mill guiding, the hydraulic oil interface of described oil cylinder is connected with high-pressure oil pipe by oil connection.
The utility model utilizes the thrust of oil cylinder by pivot barrel jack-up, because oil cylinder does not exist corrosion problem, substantially increases the reliability of rotary pivot apparatus.Present arrangement avoids the problem that in traditional guide and guard rotary pivot apparatus, bolt easily lost efficacy because of corrosion, change roll for memorial archway milling train and to provide convenience condition.
Oil cylinder is connected with pivot barrel by flange, and this connected mode has good sealing, can effectively prevent foreign matter from entering pivot barrel, thus ensure that the flexibility that guide and guard rotate; The effect of pressure bearing is the rotational resistance reducing pivot barrel, improves the operating flexibility of this device further.
The utility model structure is simple, easy to operate, reliable operation, effectively can reduce the labour intensity of workman, improves the operating efficiency changing roll.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of traditional guide and guard rotary pivot apparatus;
Fig. 2 is structural representation of the present utility model.
In figure, mark is as follows: 1, pivot mount, and 2, pivot barrel, 3, pressure bearing, 4, oil cylinder, 5, oil connection, 6, high-pressure oil pipe, 7, manual pump, 8, flange, 9, pivot body, 10, bolt.
Detailed description of the invention
The utility model provides a kind of novel memorial archway rolling mill guiding rotary pivot apparatus, this device can solve the series of problems that traditional guide and guard rotary pivot apparatus utilizes bolt jack-up pivot barrel to bring, effectively improve the operating efficiency changing roll, reduce the labour intensity of workman.
Referring to Fig. 2, the utility model comprises pivot mount 1, pivot barrel 2, pressure bearing 3, oil cylinder 4, oil connection 5, high-pressure oil pipe 6, manual pump 7, flange 8 and pivot body 9.Its implementation is: substituted by original bolt 10 80/56-100 hydraulic jack 4, and the piston rod of oil cylinder 4 to extend in pivot barrel 2 and corresponding with pivot body 9, and piston-rod lower end installs a set of pressure bearing 3.Hydraulic jack 4 and pivot barrel 2 adopt the flange 8 with eight fixing holes to be connected, and 8 screwed holes need be made a call in pivot barrel 2 top, put into sealing gasket between flange 8 and pivot barrel 2, and this flange connection has good sealing effectiveness.Hydraulic jack 4 is provided with application tube joint 5, when carrying out roll change operation, oil connection 5 is directly connected with high-pressure oil pipe 6, manual pump 7 is connected to the other end of high-pressure oil pipe 6, manual operation manual pump 7 is suppressed, cylinder piston rod declines, the pressure bearing 3 of piston-rod lower end contacts with pivot body 9, and using pivot barrel 2 jack-up as guide bracket, pivot barrel 2 is separated with pivot mount 1, now pivot barrel 2 can pivot body 9 be axle rotation, due to the existence of pressure bearing 3, this rotates as rolling friction, and resistance reduces greatly.
When using this rotary pivot apparatus, 1 people just can carry out roller replacing operation, and simultaneously due to pivot good sealing effect, guide and guard rotary course resistance is little, rotates more convenient, effectively reduces the operating time.
