Description
Technical Field
The utility model relates to a heavy and medium plate mill technical field especially relates to a heavy and medium plate mill work roll baffle pneumatic cylinder jaw device.
Background
At present, most of domestic and foreign heavy and medium plate mills are four-roller reversible mills, which are provided with a bending hydraulic cylinder, and the diameter of a working roll body is designed with convexity so as to meet the control of plate type and thickness during the rolling of a wide steel plate. The work roll shield apparatus is installed on the operating side of the heavy and medium plate mill. This device uses a hydraulic cylinder to control opening and closing. In the steel rolling process, the hydraulic cylinder drives the baffle to be in a closed state, so that the working roll is prevented from jumping outwards. During roll changing operation, the hydraulic cylinder drives the baffle to open to change the roll.
However, rolling component force along the axial direction of the working roll is inevitably generated in the steel rolling process, so that the baffle of the working roll is stressed outwards and deflects in a small amplitude, and further the cylinder rod of the hydraulic cylinder is bent, and the cylinder rod of the hydraulic cylinder is frequently broken. Once the hydraulic cylinder breaks, unnecessary trouble is brought to roll changing operation, and the replacement is difficult.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a fork head device of a hydraulic cylinder of a work roll baffle of a medium plate mill. The hydraulic cylinder rod is prevented from being broken, so that the roll changing work is normally carried out, the roll changing efficiency is improved, equipment accidents are avoided, and the yield is improved.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a fork head device of a hydraulic cylinder of a work roll baffle of a heavy and medium plate mill comprises the work roll baffle, a fork head and a hydraulic cylinder; the fork head is U-shaped and consists of a head part and two support legs connected with the head part, the head part is provided with a first pin hole, and the two support legs are provided with second pin holes; the working roll baffle is provided with a third pin hole, and the head of the fork head is hinged with the working roll baffle through the first pin hole, the third pin hole and the first pin shaft; the head of a cylinder rod of the hydraulic cylinder is hinged between the two support legs of the fork head through a second pin shaft and a second pin hole.
The head end of the fork head is semicircular.
The fixing plate is characterized by further comprising a fixing plate, a semicircular notch corresponding to the first pin shaft is formed in the middle of the fixing plate, a bolt hole is formed in the middle of the fixing plate, and the fixing plate is fixed on the working roll baffle through a bolt.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses the mode that jaw and work roll baffle are connected designs into round pin axle form, and the purpose is convenient for demolish and install. One end of the fork head connected with the hydraulic cylinder rod is also designed into a pin shaft form, the traditional threaded connection form is not adopted, and the rotation direction of the pin shaft is the same as the outward fleeing direction of the working roll baffle.
After the structure is adopted, the fork head and the hydraulic cylinder rod are connected through the pin shaft, and the rotating direction of the pin shaft is the same as the outward movement direction of the working roller baffle plate, so that when the roller moves outward, the stress of the working roller baffle plate tends to incline outward, and only the working roller baffle plate is stressed at the moment, and the inclined direction is the same as the rotating direction of the pin shaft, so that the problem that the cylinder rod is easy to break due to the connection of the traditional thread form is solved.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1-6, a fork head device of a hydraulic cylinder of a work roll baffle of a heavy and medium plate mill comprises a work roll baffle 1, a fork head 2, a hydraulic cylinder 3 and a fixing plate 7.
The fork head 2 is U-shaped and comprises a head part and two support legs 8 connected with the head part, the head part is provided with a first pin hole 4, and the end part of the head part of the fork head is semicircular. Two supporting legs 8 of the fork head 2 are provided with second pin holes 5.
The working roll baffle plate 1 is provided with a third pin hole 6, and the head of the fork head 2 is hinged with the working roll baffle plate 1 through a first pin hole 4, the third pin hole 6 and a first pin shaft 9. The head of the rod of the hydraulic cylinder 3 is hinged between the two support legs 8 of the fork head 2 through a second pin shaft 10 and a second pin hole 5.
The middle part of the fixing plate 7 is provided with a semicircular notch corresponding to the first pin shaft 9 and a bolt hole, and the fixing plate 7 is fixed on the working roll baffle plate 1 through a bolt.
The utility model discloses the mode that jaw 2 and work roll baffle 1 are connected designs into round pin axle form, and the purpose is convenient for demolish and install. One end of the fork head 2 connected with the cylinder rod of the hydraulic cylinder 3 is also designed into a pin shaft form, the traditional threaded connection form is not adopted any more, and the rotation direction of the pin shaft is the same as the outward fleeing direction of the working roll baffle plate 1.
After the structure is adopted, the fork head 2 and the cylinder rod of the hydraulic cylinder 3 are connected by the pin shaft, and the rotating direction of the pin shaft is the same as the outward movement direction of the working roller baffle plate 1, so that when the roller moves outward, the stress of the working roller baffle plate 1 tends to incline outward, at the moment, only the working roller baffle plate 1 is stressed, and the inclined direction is the same as the rotating direction of the pin shaft, so that the problem that the cylinder rod is easy to break due to the traditional threaded connection is solved.
The utility model discloses avoid pneumatic cylinder jar pole fracture to guarantee roll change work and normally go on, improve roll change efficiency, avoid the equipment accident, increase of production.
