Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, and specifically relates to a hydraulic cylinder based on hot rolling. Background Technique

[0002] A hydraulic cylinder for hot rolling is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion.

[0003] As a mechanical device, the basic function of a hydraulic cylinder is to convert hydraulic energy into mechanical energy to achieve linear reciprocating motion or oscillating motion. This conversion is achieved through the hydraulic action inside the hydraulic cylinder, which has the advantages of simple structure and reliable operation. During the hot rolling process, hydraulic cylinders play an important role. They are widely used in various mechanical devices to provide the required force and motion, thereby realizing the rolling and processing of materials.

[0004] During the operation of a conventional hydraulic cylinder, the piston rod inside the cylinder will, under the control of different oil pressures, perform structural telescopic adjustment inside the cylinder. Therefore, the piston rod itself will alternate between the inside of the cylinder and the external environment, which will cause foreign objects to be carried on the surface of the piston rod and enter the inside of the cylinder. Over time, the accumulation of foreign objects will affect the normal operation of the entire hydraulic cylinder.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a hydraulic cylinder based on hot rolling is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a hydraulic cylinder based on hot rolling to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A hydraulic cylinder based on hot rolling includes an oil cylinder assembly and a cleaning assembly. A cleaning assembly is installed at the output end of the oil cylinder assembly, and a buffer assembly is installed at the end of the oil cylinder assembly away from the cleaning assembly. Moreover, a piston rod assembly is inserted into the inside of the oil cylinder assembly. The cleaning assembly includes a fixed seat, a first cleaning ring gasket, a support frame, a stable ring frame, and a second cleaning ring gasket. A first cleaning ring gasket is installed in the middle of the inside of the fixed seat, a support frame is installed at the top of the fixed seat, the upper end of the support frame is connected to a stable ring frame, and second cleaning ring gaskets are symmetrically installed up and down in the middle of the stable ring frame.

[0008] Furthermore, the oil cylinder assembly includes an oil cylinder housing, a sealing ring, a first connecting pile, and a connection valve. A sealing ring is installed at the end of the inside of the oil cylinder housing close to the cleaning assembly, a first connecting pile is installed at the end of the outside of the oil cylinder housing away from the cleaning assembly, and a connection valve is installed on the side of the first connecting pile.

[0009] Further, two groups of the sealing rings are arranged and installed at one end inside the oil cylinder housing, and the connection valve is communicated with the inside of the oil cylinder housing.

[0010] Further, the support frames are arranged in a circular array with the fixed seat as the center, and the support frames and the stable ring frame are fixedly connected.

[0011] Further, the buffer assembly includes a buffer ring, buffer columns and a protective pad. The buffer columns are vertically installed on the top of the buffer ring, and the protective pad is connected to the top of the buffer columns.

[0012] Further, the buffer columns are arranged in a circular array with the buffer ring as the center, and the buffer columns and the protective pad are fixedly connected to each other.

[0013] Further, the piston rod assembly includes a piston rod main body, a second connecting pile, a piston main body and a shock pad. A second connecting pile is installed at one end of the piston rod main body, and a piston main body is installed at the end of the piston rod main body far from the second connecting pile.

[0014] Further, the shock pad is inlaid on one side surface of the piston main body, and the shock pad and the protective pad are made of the same material.

[0015] The utility model provides a hydraulic cylinder based on hot rolling, which has the following beneficial effects:

[0016] 1. In the utility model, by installing a cleaning component at the opening end of the oil cylinder assembly, and using the first cleaning ring pad and the second cleaning ring pad respectively penetrated by the piston rod main body, since the two are in close fit with the outer surface of the piston rod main body, when the whole piston rod assembly performs telescopic adjustment inside the oil cylinder assembly, the first cleaning ring pad and the second cleaning ring pad will rub and scrape along the surface of the piston rod main body, so as to play a role in removing foreign matters on the surface of the piston rod main body. By using the above structure, it can be avoided to the greatest extent that during the telescopic movement adjustment of the whole piston rod assembly, when the piston rod main body contacts with the external environment, the foreign matters adhered to the surface will enter the inside of the oil cylinder assembly due to the structure expansion and contraction, thus affecting the normal operation of the whole hydraulic cylinder. Therefore, by setting the structure of the cleaning component, real-time cleaning treatment can be carried out during the telescopic process of the piston rod assembly, so as to avoid this situation.

[0017] 2. In the present utility model, a buffer assembly is installed at one end inside the oil cylinder assembly. When the piston rod assembly slips structurally during the telescopic support due to the loss of pressure inside the oil cylinder housing or due to a structural failure of the piston body itself, at this time, the buffer columns arranged in an annular array around the buffer ring use the elastic telescopic movement of their structures, and cooperate with the kinetic energy absorption of the shock-absorbing pad and the protective pad to achieve good structural buffering, so as to reduce the structural collision caused by the structure falling as much as possible, thereby reducing the damage between structures. In addition, since the cleaning assembly is arranged between the second connecting pile and the opening of the oil cylinder housing, using its structure can also assist in buffering and blocking the structure of the falling piston rod assembly.

[0024] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0025] As Figures 1 to 5As shown in the figure, a hydraulic cylinder based on hot rolling includes a cylinder component 1 and a cleaning component 2. The cleaning component 2 is installed at the output end of the cylinder component 1, and a buffer component 3 is installed at one end of the cylinder component 1 away from the cleaning component 2 inside the cylinder component 1. Moreover, a piston rod component 4 is inserted inside the cylinder component 1. The cleaning component 2 includes a fixed seat 201, a first cleaning ring gasket 202, a support frame 203, a stable ring frame 204, and a second cleaning ring gasket 205. The first cleaning ring gasket 202 is installed in the middle of the fixed seat 201, and the support frame 203 is installed on the top of the fixed seat 201. Moreover, the upper end of the support frame 203 is connected to the stable ring frame 204, and the second cleaning ring gaskets 205 are symmetrically installed up and down in the middle of the stable ring frame 204. The support frames 203 are arranged in a circular array with the fixed seat 201 as the center, and the support frames 203 and the stable ring frame 204 are fixedly connected. Since the first cleaning ring gasket 202 and the second cleaning ring gasket 205 are in close contact with the outer surface of the piston rod body 401, when the entire piston rod component 4 performs telescopic adjustment inside the cylinder component 1, the first cleaning ring gasket 202 and the second cleaning ring gasket 205 will scrape along the surface of the piston rod body 401 by friction, so as to play a role in removing foreign matters on the surface of the piston rod body 401.

[0026] As Figures 1 to 5As shown in the figure, the oil cylinder assembly 1 includes an oil cylinder housing 101, a sealing ring 102, a first connecting pile 103 and a connection valve 104. A sealing ring 102 is installed at one end of the interior of the oil cylinder housing 101 close to the cleaning assembly 2, and a first connecting pile 103 is installed at one end of the outer side of the oil cylinder housing 101 away from the cleaning assembly 2. A connection valve 104 is installed on the side of the first connecting pile 103. Two groups of sealing rings 102 are arranged and installed at one end of the interior of the oil cylinder housing 101, and the connection valve 104 is communicated with the interior of the oil cylinder housing 101. The buffer assembly 3 includes a buffer ring 301, a buffer column 302 and a protective pad 303. A buffer column 302 is vertically installed at the top of the buffer ring 301, and a protective pad 303 is connected to the top of the buffer column 302. The buffer columns 302 are arranged in a circular array with the buffer ring 301 as the center, and the buffer columns 302 and the protective pads 303 are fixedly connected to each other. The piston rod assembly 4 includes a piston rod main body 401, a second connecting pile 402, a piston main body 403 and a shock pad 404. A second connecting pile 402 is installed at one end of the piston rod main body 401, and a piston main body 403 is installed at the end of the piston rod main body 401 away from the second connecting pile 402. The shock pad 404 is embedded on one side surface of the piston main body 403, and the shock pad 404 and the protective pad 303 are made of the same material. When the piston rod assembly 4 slides structurally during the telescopic support due to the loss of pressure inside the oil cylinder housing 101 or due to the structural failure of the piston main body 403 itself, at this time, the buffer columns 302 arranged in a circular array around the buffer ring 301, through the elastic telescopic movement of their structures, cooperate with the kinetic energy absorption of the shock pad 404 and the protective pad 303, so as to achieve good structural buffering.

[0027] In summary, as Figures 1 to 5 shown in the figure, when the hydraulic cylinder based on hot rolling is in use, first, the connection valve 104 installed on one side of the first connecting pile 103 is connected to the hydraulic control system through a pipeline. As the hydraulic control system injects and fills hydraulic oil inside the oil cylinder housing 101, when the piston rod assembly 4 moves and adjusts inside the oil cylinder assembly 1, at this time, the piston rod main body 401 will perform telescopic adjustment at the opening at one end of the oil cylinder housing 101 close to the sealing ring 102, so as to realize the pushing and pulling operation of the equipment or structural parts connected to one end of the second connecting pile 402. During the movement of the piston rod main body 401, the first cleaning ring pad 202 and the second cleaning ring pad 205 attached to the surface of the piston rod main body 401 will scrape relatively, so as to remove the sundries on its surface while the piston rod main body 401 retracts into the interior of the oil cylinder housing 101, preventing foreign objects from entering the interior of the oil cylinder housing 101;

[0028] When the oil pressure inside the oil cylinder housing 101 is unbalanced or a fault occurs in the contact structural surface between the piston body 403 and the oil cylinder housing 101, resulting in the failure of the structural support and a fall, at this time, under the elastic expansion and contraction of the buffer column 302, in cooperation with the energy absorption and buffering of the piston rod main body 401, it is convenient to reduce the structural collision generated by the sliding of the piston rod assembly 4 as much as possible. At the same time, the protective pad 303 and the shock pad 404 can also reduce the damage caused by the structural collision between the buffer assembly 3 and the piston rod assembly 4 as much as possible. In addition, by using the support frame 203 vertically installed on the surface of the fixed seat 201 and in cooperation with the structural setting of the stable ring frame 204, it can also play a role in structural blocking and buffering to a certain extent, and reduce the damage as much as possible.

Many modifications and variations are obvious to those of ordinary skill in the art.
