Abstract

The invention relates to a rack locking oil cylinder of a bar mill, which comprises a sealing end cap, a cylinder body, and a piston rod of which the front end is provided with a locking wedge face, and is characterized in that: the cylinder body consists of an oil cylinder and a spring pressing chamber; a plurality of disc springs are arranged inside the spring pressing chamber; the disc springs are connected with the piston rod, which penetrates through the spring pressing chamber, in a sleeving mode; one end of the piston rod which is sleeved with the disc springs is provided with a shaft sleeve; the shaft sleeve is fixedly connected with the end cap which is fixedly connected with the cylinder body; a seal ring is arranged between the oil cylinder and the spring pressing chamber; and the oil cylinder is communicated with an oil inlet hole arranged on the cylinder body. The rack locking oil cylinder of the bar mill has the advantages that: the conventional hydraulic locking and opening mode is converted into a mechanical locking and hydraulic opening mode, so that the reliability of locking work can be guaranteed, and the occurrence of the locking failure due to leakage of a hydraulic system is eliminated; therefore, the rack locking oil cylinder of the bar mill is environmentally friendly and energy-saving.

Description

The rack locking oil cylinder of bar mill
Technical field
The invention belongs to milling train, relate in particular to a kind of rack locking oil cylinder of bar mill.
Background technology
Large-sized rolling mills is locked it by locking cylinder after adjusting as the roll bed frame process of 650 type bar mills.Locking cylinder adopts hydraulic locking, hydraulic open mode, requires the coupling mechanism force of locking cylinder very big.Adopt the hydraulic locking mode of hydraulic system.If in a single day hydraulic system breaks down, produce leakage and then can cause locking cylinder locking malfunctioning, base can not be locked.
Summary of the invention
The present invention causes locking malfunctioning problem generation in order to overcome deficiency of the prior art, a kind of rack locking oil cylinder of bar mill to be provided, adopt mechanical lock, guarantee to lock reliable operation, eliminating because hydraulic system produces to leak.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of rack locking oil cylinder of bar mill, comprise end cover, cylinder body, front end has the piston rod of locking wedge surface, it is characterized in that: described cylinder body is made up of oil cylinder and spring compression chamber two parts, described spring compression chamber is built-in with several dish springs, described dish spring is connected with piston rod suit through the spring compression chamber, piston rod one end of suit dish spring is provided with axle sleeve, axle sleeve and end cap are affixed, described end cap and cylinder body are affixed, are provided with sealing ring between described oil cylinder and the spring compression chamber, and described oil cylinder is communicated with fuel feed hole on being located at cylinder body.
Beneficial effect: by original hydraulic locking and unfolding mode, change mechanical lock into, fluid pressure type is opened, and then can guarantee to lock reliable operation, eliminates because hydraulic system produces to leak to cause locking malfunctioning problem generation.Not only environmental protection but also energy-conservation.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of original locking cylinder.
The specific embodiment
Below in conjunction with preferred embodiment, to details are as follows according to the specific embodiment provided by the invention:
See accompanying drawing for details, a kind of rack locking oil cylinder of bar mill, comprise that end cover 1, cylinder body 2, front end have the piston rod 3 of locking wedge surface, described cylinder body is made up of oil cylinder 2-1 and spring compression chamber 2-2 two parts, described spring compression chamber is built-in with several dish springs 4, described dish spring is connected with piston rod suit through the spring compression chamber, piston rod one end of suit dish spring is provided with axle sleeve 5, axle sleeve and end cap 1 are affixed, described end cap and cylinder body are affixed, be provided with sealing ring 6 between described oil cylinder and the spring compression chamber, described oil cylinder is communicated with fuel feed hole 7 on being located at cylinder body.
Operation principle: be hydraulic locking originally, the hydraulic open formula changes mechanical interlocking into, after this mechanism of hydraulic open is used for 650 bar mill rack locking milling trains location, counter-force by the dish spring makes its check lock lever and frame locating surface compress the pinning frame, when adjusting the position, hole and changing rod, by the counter-force of hydraulic oil, make its dish spring compression, drive the check lock lever displacement, realize releasing orientation, after frame is located by technological requirement, hydraulic pressure is let out and is closed, by the counter-force lock-bit of dish spring.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
