Description

Technical Field

[0001] The utility model relates to the field of steel rolling guides, in particular to a permanent fixing device for steel rolling guides. Background Art

[0002] The rolling mill guide is a component used to guide the rolled piece into the equipment for processing. The guiding effect of the guide device will directly affect the quality of the rolled piece. The existing guide devices are installed in the corresponding groove on the side of the equipment through the dovetail table at the tail, and then fixed. However, since the dovetail table needs to be stuck into the groove, the size of the groove must be larger than the size of the dovetail table. In this way, the guide device will inevitably be loose after installation. The existing device has a poor fixing effect on it and the fixed structure cannot be fixed well and permanently, and it is often easy to loosen and cause production accidents.

[0003] The utility model disclosed in the publication (announcement) number: CN214813631U discloses a permanent fixing device for a steel rolling guide, comprising an outer frame, an installation groove is provided inside the outer frame, a guide device is movably connected in the installation groove, a dovetail platform is fixedly installed on the left end of the guide device, a fixing pin is installed through the left side of the outer frame, and a first screw is threadedly connected through the upper left side of the top of the outer frame. The permanent fixing device for the steel rolling guide is implemented by inserting the dovetail platform into the corresponding position in the installation groove and then inserting the fixing pin into the dovetail platform. The fixing pin electromagnetically absorbs the dovetail platform to ensure the initial fixation of the position of the dovetail platform, and then the first screw and the second screw are turned, the first screw drives the side pressure plate to press the upper end of the dovetail platform, and the second screw presses the groove on the outer surface of the guide device, thereby stably and durably pressing and fixing the guide device, thereby improving the effect of the fixing device.

[0004] The device of the utility model has a first screw and multiple second screws to press and fix the guide device. However, in the actual installation process, the installation process of multiple screws is labor-intensive. At the same time, the mechanical vibration generated during the operation process can easily cause the thread to loosen, thereby causing the screw to fall off and cause an accident.

[0018] Embodiment 1

[0019] See also Figure 1-Figure 2The figure shows a permanent fixing device for a steel rolling guide, comprising an outer frame 1, a guide device 3 is movably installed inside the outer frame 1, and a dovetail platform is provided at one end of the guide device 3 close to the outer frame 1, the outer frame 1 is fixedly installed at one end of the dovetail platform of the guide device 3 through a first installation component 2 at the center position of one end away from the guide device 3, and the two sides of the outer frame 1 are fixedly installed on both sides of the guide device 3 through a plurality of second installation components 4.

[0020] In this embodiment, the first mounting assembly 2 and the second mounting assembly 4 both include a mounting tube 41 fixedly connected to one end of the outer frame 1, and a limit rod 42 is slidably penetrated at the center position of the mounting tube 41, and the outer frame 1 is respectively provided with a through slide groove 101 slidably penetrated with each limit rod 42, and the center position of one end of the guide device 3 near the dovetail platform is provided with a first limit groove 301 that is clamped and adapted with the limit rod 42 of the first mounting assembly 2 away from the end of the mounting tube 41, and the two sides of the guide device 3 are respectively provided with limit grooves 101 that are connected with each second mounting assembly 4. One end of the positioning rod 42 is clamped in the matching second limiting groove 302, and a slide plate 43 is slidably arranged in each mounting tube 41, and the slide plate 43 is sleeved and fixed on the outside of the limiting rod 42, and a spring is sleeved on the outside of the limiting rod 42, and the two ends of the spring are respectively abutted against the top of the inner wall of the mounting tube 41 and the end of the slide plate 43 away from the outer frame 1, and both sides of the mounting tube 41 of each second mounting assembly 4 are respectively provided with sockets 44 fixedly connected to one end of the outer frame 1, and the top of the limiting rod 42 is plugged and fixed with the two sockets 44 through a plug rod 45 arranged in the horizontal direction.

[0021] Furthermore, the limit rod 42 is pulled out through the pull ring provided at one end of the limit rod 42 of the first mounting assembly 2 so that the limit rod 42 moves away from one end of the mounting tube 41 and enters the through-slide groove 101, and the dovetail stage of the guide device 3 is inserted into the outer frame 1, so that when the guide device 3 slides to the first limit groove 301 facing the limit rod 42 of the first mounting assembly 2, the elasticity of the compressed spring causes the limit rod 42 to be sent into the first limit groove 301, thereby achieving the preliminary fixation of the dovetail stage of the guide device 3. At the same time, the limit rod 42 of the first mounting assembly 2 applies a horizontal extrusion force to the dovetail stage of the guide device 3 under the elastic force of the spring, thereby reducing the dovetail stage of the guide device 3. The possibility of shaking occurs. At the same time, when the limiting rod 42 of each second mounting assembly 4 is facing the second limiting grooves 302 corresponding to the two sides of the outer frame 1, by pulling out each horizontally arranged plug rod 45, the limiting of the plug rod 45 and the two sockets 44 on the top of the limiting rod 42 is released, so that the plug rod 45 is separated from the through hole adapted to the top of the limiting rod 42 and the plug rod 45. Under the elastic force of the compressed spring, the slide plate 43 moves vertically along the inside of the mounting tube 41 toward the outer frame 1, thereby driving the limiting rod 42 to be clamped and fixed to one end of the outer frame 1 with each second limiting groove 302, thereby permanently fixing the guide device 3, simplifying the installation steps and reducing the workload.

The tail stage may shake, and at the same time, when the limit rod 42 of each second mounting assembly 4 is facing the second limit grooves 302 corresponding to the two sides of the outer frame 1, by pulling out each horizontally arranged plug rod 45, the limit of the plug rod 45 and the two sockets 44 on the top of the limit rod 42 is released, so that the plug rod 45 is separated from the through hole adapted to the top of the limit rod 42 and the plug rod 45, and under the elastic force of the compressed spring, the slide plate 43 moves vertically along the inside of the mounting tube 41 toward the outer frame 1, thereby driving the limit rod 42 to be clamped and fixed to one end of the outer frame 1 with each second limit groove 302, thereby permanently fixing the guide device 3, simplifying the installation steps and reducing the workload.
