[0002] In the traditional steel rolling process, the heating furnace is an essential piece of equipment. During the tapping process, the steel expands due to heat, causing it to shift, disrupting subsequent processes. Currently, most straightening equipment on the market relies on manual adjustment, which is not only inefficient but also poses safety risks.

The push rod consists of a tubular tube with a top cover, a flange, an inlet pipe, a return pipe, and a positioning plate. This device straightens the returned billet, allowing it to be tapped smoothly. This patent straightens the billet from one side, but as the billet moves on the cantilever roller, it can slip, making it difficult to straighten it in one go with a single-sided push.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0022] Combine Figure 1-Figure 4 The steel-tapping pushing device of the steel rolling heating furnace of the present invention includes a mounting base 1, on which a lateral pushing component 2 is installed. The lateral pushing component 2 works on the mounting base 1, and the mounting base 1 drives the lateral pushing component 2 to move along the distribution direction of the cantilever roller. In order to enable the mounting base 1 to also change its working position, a displacement component 3 is installed on the mounting base 1. The displacement component 3 is arranged above the cantilever roller along the distribution direction of the cantilever roller, and the mounting base 1 drives the lateral pushing component 2 to work downward.

[0023] Specifically, the lateral pushing assembly 2 includes a drive motor 21, a drive gear 22, a sliding rack 23, a synchronous plate 24 and a pushing pipe 25. The drive motor 21 is installed on the upper surface of the mounting seat 1, and the output end of the drive motor 21 passes through the mounting seat 1. The output end of the drive motor 21 placed in the mounting seat 1 is fixedly connected to the drive gear 22. The drive gear 22 rotates under the control of the drive motor 21, driving the sliding rack 23 engaged with it to move toward or in the opposite direction. One end of the sliding rack 23 is fixedly connected to the synchronous plate 24, and a pushing pipe 25 is installed on the synchronous plate 24. The sliding rack 23 drives the pushing pipe 25 to move toward each other through the synchronous plate 24, pushing the offset billet from both sides of the billet at the same time, which can prevent the billet from sliding laterally on the cantilever roller and push the billet closer to the center line of the cantilever roller.

[0024] In order to improve the stability of the sliding rack 23, a first slide bar 231 is fixedly connected to one side of the sliding rack 23, and a first slide groove 11 matching the first slide bar 231 is opened on the inner wall of the mounting seat 1. The first slide bar 231 moves in the first slide groove 11, and second slide bars 241 movably connected to the mounting seat 1 are provided at both ends of the upper surface of the synchronous plate 24. The second slide bar 241 slides in the second slide groove 12 provided on the lower surface of the mounting seat 1. Under the action of the first slide bar 231 and the second slide bar 241, the positions of the sliding rack 23 and the synchronous plate 24 on the mounting seat 1 are fixed, while ensuring the smooth operation of the sliding rack 23 and the synchronous plate 24.

[0025] In this embodiment, the pushing pipe 25 is formed by connecting several U-shaped pipes. The U-shaped pipe contacts the steel billet and pushes the steel billet to the correct position. The U-shaped pipes arranged in parallel form multiple steel billet contact points to correct the position of the steel billet. A liquid inlet 251 is provided at one end of the pushing pipe 25, and a liquid outlet 252 is provided at the other end of the pushing pipe 25. The liquid inlet 251 and the liquid outlet 252 both pass through the end of the synchronous plate 24. The synchronous plate 24 drives the pushing pipe 25 to move its position. The pushing pipe 25 contacts the steel billet to push the steel billet to the correct position. The liquid inlet 251 and the liquid outlet 252 are both connected to the hose and can be moved to the synchronous plate 24 without affecting the flow of liquid.

[0026] In this embodiment, the displacement assembly 3 consists of a screw rod 31 and a guide rod 32. The upper surface of the mounting seat 1 is provided with a threaded sleeve 13 engaged with the screw rod 31. The upper surface of the mounting seat 1 is also provided with a guide sleeve 14 engaged with the guide rod 32. The screw rod 31 is driven to rotate, and the threaded sleeve 13 drives the mounting seat 1 to move along the direction of the guide rod 32, thereby changing the position of the mounting seat 1. The working position of the mounting seat 1 is adjusted according to the offset position of the billet when it moves, so that the billet on the entire cantilever roller line can be pushed straight.

[0027] The temperature of the steel billets coming out of the steel rolling heating furnace is relatively high, and they will generate heat when they come into contact with air. The mounting base 1 is provided with heat dissipation holes 15, which can reduce the weight of the mounting base 1 and accelerate the diffusion of the heat.

[0028] Working process: When the billet moves on the cantilever roller, the position of the billet is monitored at all times. When the position is offset, the drive screw 31 is rotated to drive the mounting base 1 to move above the offset billet position. The drive motor 21 works to drive the drive gear 22 to rotate, and the sliding rack 23 moves toward each other, driving the synchronous plate 24 and the pushing pipe 25 to move toward each other. The pushing pipe 25 moves toward the billet from both sides of the billet at the same time. The local position of the pushing pipe 25 first contacts the billet. As the sliding rack 23 slides, the pushing pipe 25 pushes the billet straight until the billet contacts all U-shaped parts on the pushing pipe 25. The drive motor 21 controls the drive gear 22 to reverse, and the sliding rack 23 drives the pushing pipe 25 to release the billet.
