Description

Technical Field

[0001] The present application relates to the field of hydraulic pushers, and in particular to a hydraulic pusher with a buffer protection structure. Background Art

[0002] The hydraulic pusher is a steel-pushing machine that uses a hydraulic cylinder to drive a push head through a piston rod to move the rolled piece. It is used to push steel in a heating furnace. The hydraulic pusher mainly includes components such as a chassis, a hydraulic cylinder, a push beam and a hydraulic push rod.

[0003] Announcement No. CN 213090482 U discloses a hydraulic steel pusher with a buffer protection structure. When the push plate collides with steel, its impact force pushes the push plate to rebound to the right. First, the three telescopic rods are squeezed to initially reduce the impact force on the push plate. Then, the left and right pressure strips squeeze the connecting spring, so that the distance between the upper and lower movable blocks is shortened. The extrusion spring is squeezed through the restriction of the sleeve. The extrusion deformation generated by the connecting spring and the extrusion spring further reduces the impact force on the push plate, thereby greatly reducing the damage to the push rod and the hydraulic cylinder when the device collides with the steel, so that the equipment has high safety performance, thereby greatly improving the stability and service life of the device.

[0004] However, there are some defects in the above scheme: in the above scheme, a buffer structure is set between the hydraulic cylinder and the push plate, and a spring is used to buffer the impact force. However, since it is close to the furnace mouth and is affected by the high temperature in the furnace, the spring is easily affected by the high temperature and the large extrusion pressure, resulting in the loss of elastic force buffering effect. In addition, the push plate of the pusher is mostly fixed. The same type of pusher is used for the same type of heating furnace, and the adaptability is relatively single. Utility Model Content

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0031] See also Figure 1-Figure 4 The present application provides a hydraulic steel pusher with a buffer protection structure, including a driving component 100 and a pushing component 200.

[0032] See also Figure 1 The driving assembly 100 includes a base plate 110, a hydraulic cylinder 120, a sliding rod 130, an elastic member 140 and a movable plate 160. The hydraulic cylinder 120 is arranged on the top of the base plate 110, the sliding rod 130 is slidably arranged on the top of the base plate 110, the elastic member 140 is sleeved on the surface of the sliding rod 130, and the movable plate 160 is fixedly connected to the hydraulic cylinder 120 and slidably sleeved on the surface of the sliding rod 130.

[0033] Among them, the elastic member 140 includes a fixing ring 141 and a spring 142. The fixing ring 141 is fixedly sleeved on the surface of the sliding rod 130, and the spring 142 is sleeved on the surface of the sliding rod 130. The spring 142 is located between the fixing ring 141 and the movable plate 160. By setting the fixing ring 141 and the spring 142, the elastic effect of the spring 142 is used to buffer the impact force during contact, thereby reducing damage to the hydraulic cylinder 120.

[0034] Specifically, one end of the sliding rod 130 is fixedly connected to a limiting plate 131, and two sliding rods 130 are symmetrically arranged. By setting the limiting plate 131, when the hydraulic cylinder 120 pushes the moving plate 160 to move, the moving plate 160 pushes the limiting plate 131 to achieve the purpose of driving the sliding rod 130 to move.

[0035] In a specific implementation, a fixing seat 111 is provided on the top of the bottom plate 110, and the sliding rod 130 slides through the fixing seat 111. The fixing seat 111 is provided to stably support the sliding rod 130 to slide through the fixing seat 111, thereby realizing a sliding connection.

[0036] In a specific implementation, a reinforcing rib 161 is provided on the side of the movable plate 160 away from the hydraulic cylinder 120. By providing the reinforcing rib 161, the structural strength of the movable plate 160 is enhanced to make it more solid.

[0037] See also Figure 1 , 2 , 3 and 4, the pushing assembly 200 includes a connecting plate 210, a pushing plate 220 and a connecting piece 250, the connecting plate 210 is arranged at the end of the sliding rod 130, two pushing plates 220 are symmetrically arranged, the pushing plate 220 is sleeved on one side of the connecting plate 210, and the connecting piece 250 is connected between the two pushing plates 220.

[0038] Among them, a T-shaped block 211 is set on one side of the connecting plate 210, and a T-shaped slot 222 is opened on one side of the pushing plate 220. The T-shaped block 211 and the T-shaped slot 222 are adapted to each other. By setting the T-shaped block 211 and the T-shaped slot 222 to be adapted to each other, the pushing plate 220 is inserted into the T-shaped block 211 for connection.

[0039] Specifically, the connecting member 250 includes a connecting rod 251 and a positioning rod 252. The positioning rod 252 passes through the connecting rod 251 and is connected to the pushing plate 220. By setting the connecting rod 251 and the positioning rod 252, the positioning rod 252 passes through the connecting rod 251 and is connected to the pushing plate 220, thereby realizing the spacing adjustment and positioning of the two pushing plates 220.

[0040] In this embodiment, the push plate 220 is provided with a plurality of positioning grooves 223, and the positioning rod 252 is threadedly connected to the positioning groove 223. By providing a plurality of positioning grooves 223, the positioning rod 252 is screwed into the corresponding positioning groove 223 after the push plate 220 adjusts the spacing to achieve a positioning connection.

[0041] The working principle of the hydraulic steel pusher with a buffer protection structure is as follows: when in use, the hydraulic cylinder 120 is activated to contract, and the hydraulic cylinder 120 drives the moving plate 160 to move. The moving plate 160 first slides along the sliding rod 130, and then the moving plate 160 squeezes the fixing ring 141 and the spring 142, so that the fixing ring 141 drives the sliding rod 130 to move, and the sliding rod 130 moves stably under the support of the fixing seat 111, and the sliding rod 130 pushes the connecting plate 210 and the pushing plate 220 to move, and the pushing plate 220 contacts the extruded steel billet, and then the reaction force acts Used on the sliding rod 130, the spring 142 is squeezed, and the elastic effect of the spring 142 is used for buffering, thereby reducing the impact on the hydraulic cylinder 120. At the same time, for different types of heating furnaces, the two push plates 220 can be moved to adjust the spacing, and then the positioning rod 252 passes through the connecting rod 251, and the positioning rod 252 is screwed into the corresponding positioning groove 223 to achieve positioning connection, thereby improving the scope of application. The push plate 220 is arranged in reverse at the tail end of the hydraulic cylinder, so that the spring 142 and the hydraulic cylinder 120 are away from the furnace mouth to reduce the impact of high temperature.

[0042] It should be noted that the specific model and specifications of the hydraulic cylinder 120 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0043] The power supply and principle of the hydraulic cylinder 120 are clear to those skilled in the art and will not be described in detail here.
