Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of section steel pipe rolling technology, in particular to a guard plate for reducing rail rolling marks. Background Technique
[0002] In the process of rail production, universal rolling mills are mainly used in China. This is an efficient and precise rolling method that can ensure that the geometric dimensions and surface quality of the rails meet high-standard requirements. However, during the rolling process, as a key component for controlling the rolling state of the rails, the design and performance of the guard plate directly affect the final quality of the rails;
[0003] At present, the widely used guard plate design has significant limitations. First of all, since the front tip part of the guard plate is narrower than the main body, this design often fails to ensure the axial stability of the rail when guiding the rolled piece into the pass. In a high-speed and high-pressure rolling environment, the rail is prone to axial movement, especially at the lower jaw of the rail head or the connection between the waist and legs, and these parts are prone to collide with the roll. This kind of collision not only aggravates the wear of the roll, but also causes a large amount of scale to adhere to the surface of the roll, and then obvious rolling marks are formed during the subsequent rolling process, seriously affecting the surface quality of the rail. Secondly, most of the existing guard plates are of integral design. Once the working surface of the guard plate is damaged due to long-term use, it often means that the entire guide device needs to be scrapped. This design not only increases the production cost, but also causes great waste of resources. Therefore, we propose a guard plate for reducing rail rolling marks to solve the above problems.

There are two mounting parts 3 on the support 1. A cavity 4 is formed in the support 1. A support block 5 is welded to the inner wall of the top of the cavity 4. Fixed rods 6 are welded to both sides of the support block 5. A latch 7 is slidably connected to the fixed rods 6. A spring 8 is welded between the end of the latch 7 and one side of the support block 5. The spring 8 is movably sleeved on the corresponding fixed rod 6. Fixed pulleys 9 are rotatably connected to both sides of the support block 5. The end of the latch 7 is fixedly connected to a flexible steel cable 10. The end of the flexible steel cable 10 extends outside the support 1 and is fixedly connected to a pull rod 11. Two mounting columns 12 are fixedly connected to the bottom of the guard plate tongue 2. A clamping groove 13 is formed on one side of the mounting column 12. The clamping groove 13 is engaged with the corresponding latch 7. By increasing the width of the tip of the guard plate tongue 2, the axial movement of the rolled piece during the biting process is restricted, the impact of the rolled piece on the roll is reduced, the production of rolling mark rejects is reduced, the situation of roll sticking with iron scale is alleviated, the service life of the roll is improved, the rolling volume of the roll is increased, the roll consumption is reduced. When it is necessary to replace the guard plate tongue 2, pull the pull rod 11. The pull rod 11 drives the corresponding latch 7 to move through the flexible steel cable 10. The latch 7 slides on the corresponding fixed rod 6 and compresses the spring 8, so that the latch 7 is separated from the corresponding clamping groove 13. Then move the guard plate tongue 2. The guard plate tongue 2 drives the mounting column 12 to be separated from the support 1, so as to remove the damaged guard plate tongue 2. Insert the mounting column 12 on the new guard plate tongue 2 into the cavity 4 through a rectangular hole 14. When the bottom of the guard plate tongue 2 contacts the top of the support 1, at this time, release the pulling force on the pull rod 11. The spring 8 in the compressed state resets. Under the action of the self-elastic force of the spring 8, the spring 8 drives the corresponding latch 7 to be engaged with the clamping groove 13, so as to fix it. There is no need to replace the whole, and the production cost is reduced.
[0023] In some embodiments, two rectangular holes 14 are formed in the inner wall of the top of the cavity 4. The inner wall of the rectangular hole 14 is in movable contact with the outer side of the corresponding mounting column 12. The setting of the rectangular hole 14 plays a role in limiting.

[0027] During operation or in terms of the structural principle, when in use, by increasing the width of the tip of the guard plate tongue 2, the axial movement of the rolled piece during the biting process is restricted, the impact of the rolled piece on the roll is reduced, the occurrence of defective products with rolling marks is reduced, the situation of the roll sticking with scale is alleviated, the service life of the roll is increased, the rolling output of the roll is increased, the roll consumption is reduced. When the guard plate tongue 2 needs to be replaced, the pull rod 11 is pulled. The pull rod 11 drives the corresponding pin 7 to move through the flexible steel rope 10. The pin 7 slides on the corresponding fixed rod 6 and compresses the spring 8, so that the pin 7 is separated from the corresponding card slot 13. Then the guard plate tongue 2 is moved, and the guard plate tongue 2 drives the mounting post 12 to be separated from the support 1, so as to remove the damaged guard plate tongue 2. The mounting post 12 on the new guard plate tongue 2 is inserted into the cavity 4 through the rectangular hole 14. When the bottom of the guard plate tongue 2 contacts the top of the support 1, the pulling force on the pull rod 11 is released at this time. The spring 8 in the compressed state resets, and under the action of its own elastic force, the spring 8 drives the corresponding pin 7 to be engaged with the card slot 13, so as to fix it. There is no need for overall replacement, and the production cost is reduced.
