Technical Field
The utility model relates to a continuous rolling mill AGC pushes up hydro-cylinder field.
Background
At present, the arrangement modes of AGC cylinders of continuous rolling mills at home and abroad are 2, wherein one mode is that ACG cylinders of European and American series or domestic continuous rolling mills are almost all arranged at the top of the rolling mill, namely pressing-down cylinders, and the other mode is that AGC cylinders of continuous rolling mills designed by Mitsubishi of Japan are arranged at the bottom of a memorial archway, namely pressing-up cylinders. The AGC screwdown oil cylinder is convenient to disassemble and assemble integrally, the installation technology of the position detection element is mature, and the detection element can be detached from the bottom of the oil cylinder directly on line. The oil cylinder is a patented product, the whole disassembly and assembly time of the oil cylinder is about 36-48 hours, the position detection element can be disassembled on line, but the structural design requirements on the oil cylinder and the detection element installation device are high, the processing and manufacturing difficulty is high, and the purchase cost of the oil cylinder is extremely high. At present, most domestic steel mills adopting the Mitsubishi Hitachi continuous rolling line still adopt the AGC pressing oil cylinder originally imported from the Mitsubishi Hitachi. The installation structure of the position detection element of the oil cylinder on the small part of the domestic AGC press is designed according to the press-down oil cylinder, and the detection element can only be replaced after the oil cylinder is detached. The 1450 continuous rolling mill for rolling the silicon steel by the Tai steel is designed and manufactured by Mitsubishi Hitachi, and the AGC cylinder is also arranged at the bottom of the housing. The first domestic trial production of spare parts is carried out on the tai-steel in 2016, the tai-steel is operated normally in 2018, but similar structural defects exist, when a position detection element of an AGC (automatic gain control) oil cylinder breaks down and needs to be checked or replaced, the position detection element needs to be integrally disassembled to implement, a large amount of capacity is sacrificed for a continuous rolling mill, and the production requirement cannot be met to a certain extent.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: how to reduce the manufacturing difficulty of an AGC pressing oil cylinder of a processing continuous rolling mill to meet the normal use requirement of the AGC pressing oil cylinder and solve the problem of difficulty in online dismounting and mounting of an AGC oil cylinder detection element.
The utility model adopts the technical proposal that: the utility model provides a tandem mill AGC presses up hydro-cylinder position detection component installation device, including hydro-cylinder (1), hydro-cylinder piston (2), magnetic scale and clamping device (4), magnetic scale gland (5), magnetic scale installation device (6), spring (7), magnetic ring fixed knot constructs (8), magnetic ring (9), magnetic ring adjusting shim plate (10), magnetic scale protection tube (11), detection component installation base, there is a step through hole groove corresponding to the position at magnetic scale gland (5) top on hydro-cylinder piston (2), through bolt installation piston top cap (3) in the step through hole groove, detection component installation base comprises interior outer sleeve, there is the step on the outside upper portion of inner skleeve (12), inner skleeve (12) embolia outer sleeve (13) back pass through the bolt fastening together in the step position.
The utility model has the advantages that: the utility model discloses not only guarantee AGC hydro-cylinder normal use and realize the position detection, reduced the productivity loss when tandem mill changes position detection component simultaneously, improved unit operating efficiency.

FIG. 2 is a schematic diagram of a prior art structure;
the device comprises an oil cylinder barrel 1, an oil cylinder piston 2, a piston top cover 3, a magnetic scale and a clamping device thereof 4, a magnetic scale gland 5, a magnetic scale mounting device 6, a spring 7, a magnetic ring fixing structure 8, a magnetic ring 9, a magnetic ring adjusting backing plate 10, a magnetic scale protecting tube 11, an inner sleeve 12 and an outer sleeve 13.
Detailed Description
As shown in fig. 1 and fig. 2, the utility model is an improvement on the basis of the existing continuous rolling mill AGC pressing-up oil cylinder.
The AGC cylinder is installed at the bottom of a rolling mill housing, belongs to a pressing cylinder, and the position detection element installation device is designed to be capable of checking and replacing detection elements on line on the premise of not disassembling the cylinder. The mounting base is the foundation for mounting the whole position detection element, is fixed at the bottom of the cylinder barrel 1 of the oil cylinder and simultaneously penetrates through the cylinder barrel 1 and the piston 2. When the oil cylinder piston moves up and down along the mounting base and the inner wall of the cylinder barrel, pressure oil is prevented from leaking to form a groove on the mounting base, and sealing is arranged. In the embodiment, the existing mounting base is divided into two parts, one part is an inner sleeve 12 and the other part is an outer sleeve 13, and the inner sleeve 12, the magnetic scale protection tube 11, the magnetic ring adjusting base plate 10, the magnetic ring 9 and the magnetic ring fixing structure 8 are sequentially mounted on the outer sleeve 13. The magnetic ring fixing structure 8 has two functions, one is used for pressing and fixing the magnetic ring 9, and the other is provided with the fixing spring 7. The other end of the spring 7 is fixed below the magnetic scale mounting device 6. The magnetic scale gland 5, the magnetic scale 4 and the magnetic scale mounting device 6 fix the magnetic scale as a whole. It is press-fitted inside the piston by the piston top cover 3. When the AGC presses the oil cylinder to act, the magnetic scale mounting base, the magnetic scale 4 and the magnetic scale top cover 5 integrally follow the oil cylinder piston to act up and down under the action of the spring.
In the embodiment, the top end of the oil cylinder piston is provided with a hole, and the piston top cover 3 is added, so that the basic condition of taking out the position detection element from the top of the oil cylinder is realized. The utility model discloses position detection element installs base in figure 2 has made 12, 13 two parts, has realized the installation from bottom to top of position detection element. When the magnetic scale or the magnetic ring of the detection element needs to be replaced, the magnetic scale and the clamping device 4, the magnetic scale gland 5 and the magnetic scale installation device 6 can be integrally detached after the piston top cover 3 is opened and detached, and then the magnetic scale 4 is taken out. Then the magnetic ring fixing structure 8 and the magnetic ring mounting structure 12 are disassembled, and the magnetic ring 9 can be taken out.
