Abstract
Description
Technical Field
[0001] The invention relates to the technical field of annealing furnaces, and in particular to a roller anti-bending device in a wide titanium plate heating annealing furnace. Background Art
[0002] Titanium plates, made from pure titanium or titanium alloys, possess excellent properties and characteristics, making them useful in aerospace, chemical and marine industries, medical devices, automotive, sporting goods, and electronics. When hot-rolling titanium plates, pre-melted titanium alloys or pure titanium are heated to a high temperature. Then, through processes such as rolling, the titanium material is gradually pressed into the desired shape and size at high temperatures, ultimately resulting in the titanium plate.
[0003] When titanium plates are prepared, they need to be heated and annealed. During this process, the rollers in the annealing furnace are prone to bending. After research and analysis, the following reasons were found: 1. When heating and annealing the titanium plates, due to the high temperature in the furnace, the rollers are exposed to high temperature for a long time, which causes them to deform due to thermal expansion and thermal stress. 2. The wide titanium plates themselves are heavy, which applies a large load pressure to the rollers during the heating and annealing process. Prolonged downward pressure can easily cause the rollers to bend. The existing treatment method is to replace the bent rollers, which has a short service life, wastes resources, and is inconvenient to use.
[0004] Therefore, the present application provides a roller anti-bending device for a wide-width titanium plate heating annealing furnace to solve the above-mentioned problems. Summary of the Invention

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0022] See also Figure 1-4 The present invention provides a technical solution: a roller anti-bending device in a wide-width titanium plate heating annealing furnace, comprising a roller conveyor, the roller conveyor comprising a straightening support frame 1, a plurality of evenly distributed conveying rollers 2 are movably provided on the side of the straightening support frame 1, both ends of the conveying roller 2 are provided with a fixed plate 3, and the conveying roller 2 is rotatably connected to the fixed plate 3, and one of the fixed plates 3 is provided with a driver for driving the conveying roller 2 to rotate. When the driver drives the conveying roller 2 to rotate, the conveying roller 2 can convey the titanium plate.
[0023] A continuous annealing furnace 7 is provided on the straightening support frame 1. The straightening support frame 1 divides the conveying roller 2 into a first working part and a second working part. A hydraulic cylinder 6 is provided at the bottom of the straightening support frame 1 for controlling the position of the first working part and the second working part. When the titanium plate exits the continuous annealing furnace 7 and moves to other conveyors, the two groups of hydraulic cylinders 6 are controlled to work. The hydraulic cylinder 6 drives the conveying roller 2 to move through the fixed plate 3. The conveying roller 2 passes through the straightening support frame 1, and the first working part of the conveying roller 2 is straightened by the left part of the straightening support frame 1. At this time, the second working part of the conveying roller 2 moves to the lower side of the continuous annealing furnace 7. At this time, the second working part serves as the working part to convey the titanium plate.
[0024] Furthermore, the driver includes a servo motor 4 installed at one end of the side of the fixed plate 3, two gears are provided on the conveying shaft of the conveying roller 2, and a gear is provided on the output shaft of the servo motor 4. The gear on the servo motor 4 is connected to the gear on the adjacent conveying roller 2 through a chain. In the direction away from the servo motor 4, the gears on the two adjacent conveying rollers 2 are connected by a chain. In the roller conveyor, when the servo motor 4 rotates, the conveying roller 2 is driven to rotate through the gear and chain. When the conveying roller 2 rotates, the titanium plate can be conveyed. The roller conveyor is used as a roller of the annealing furnace to convey the titanium plate.
[0025] Furthermore, a support leg 5 is provided at the bottom of the fixing plate 3 , and a caster 51 is provided at the bottom of the support leg 5 . The bottom of the caster 51 is flush with the bottom of the straightening support frame 1 . The support leg 5 with the caster 51 can support the fixing plate 3 .
[0026] Furthermore, the hydraulic cylinder 6 includes two groups, the fixed ends of the two groups of hydraulic cylinders 6 are arranged at the bottom of the straightening support frame 1, and the telescopic end of one group of hydraulic cylinders 6 is connected to the fixed plate 3 on the left, and the other group of hydraulic cylinders 6 is connected to the fixed plate 3 on the right. One group of hydraulic cylinders 6 pulls the conveyor roller 2 to move through the fixed plate 3, and the other group of hydraulic cylinders 6 pushes the conveyor roller 2 to move through the other fixed plate 3. The conveyor roller 2 is straightened when passing through the conveyor roller 2.
[0027] When the hydraulic cylinder 6 is pulling or pushing the conveyor roller 2, if the conveyor roller 2 is not deformed, the resistance encountered by the conveyor roller 2 when passing through the straightening support frame 1 is small, and the pressure gauge value in the external hydraulic system is small at this time; on the contrary, if the conveyor roller 2 is deformed, the resistance encountered by the conveyor roller 2 when passing through the straightening support frame 1 is small, and the pressure gauge value in the external hydraulic system is large at this time; whether the conveyor roller 2 is deformed can be detected by observing the pressure gauge value in the external hydraulic system.
[0028] Furthermore, while one group of hydraulic cylinders 6 extends, the other group of hydraulic cylinders 6 shortens synchronously, and the extension speed and shortening speed of the two groups of hydraulic cylinders 6 remain consistent, so as to synchronously pull or push the conveying roller 2.
[0029] The servo motor 4 used in the present invention is a commonly used electronic component in the prior art. Its working mode and circuit structure are well-known technologies and are not described in detail here. The servo motor 4 is electrically connected to the external switch group. The continuous annealing furnace 7 is an annealing equipment commonly used in the prior art. The roller conveyor is the roller conveyor used in the continuous annealing furnace 7 of the present invention. The hydraulic cylinder 6 is connected to the external hydraulic system through an oil pipe to control the extension and contraction of the hydraulic cylinder 6. The external hydraulic system can detect the pressure of the oil pressure when the hydraulic cylinder 6 is extended and contracted.
[0030] When using:
[0031] Working principle of roller conveyor during transportation:
[0032] When the servo motor 4 rotates, the conveying roller 2 is driven to rotate through the gears and chains, and the conveying roller 2 can convey the titanium plate when it rotates;
[0033] The working principle of titanium plate heating annealing is as follows: Figure 1 For reference:
[0034] In the initial stage, the first working portion of the conveyor roller 2 is located at the lower side of the continuous annealing furnace 7. The conveyor roller 2 conveys the titanium plate into the continuous annealing furnace 7, and the continuous annealing furnace 7 performs heating and annealing operations on the titanium plate.
[0035] The continuous annealing furnace 7 heats the titanium plate and also heats the first working portion of the conveyor roller 2. At this time, under the action of the titanium plate and the gravity of the conveyor roller 2, the first working portion of the conveyor roller 2 is prone to deformation.
[0036] After the titanium plate exits the continuous annealing furnace 7 and moves to another conveyor, the two groups of hydraulic cylinders 6 are controlled to work. The hydraulic cylinders 6 drive the conveyor rollers 2 to move through the fixed plate 3. The conveyor rollers 2 pass through the straightening support frame 1, and the first working portion of the conveyor rollers 2 is straightened by the left part of the straightening support frame 1. At this time, the second working portion of the conveyor rollers 2 moves to the lower side of the continuous annealing furnace 7.
[0037] After the second working part is deformed, repeat the previous step to move the conveyor roller 2 in the opposite direction, and straighten the second working part on the right side of the straightening support frame 1. The first working part is moved back to the lower side of the continuous annealing furnace 7. While replacing the first working part and the second working part, the deformed part of the conveyor roller 2 can be straightened, which can improve the conveying life of the conveyor roller.
[0038] The present invention divides the conveyor roller 2 into two working parts, which can work alternately. In the process of replacing the working part of the conveyor roller 2, the bent part of the conveyor roller 2 can be straightened, which helps to smoothly pass and convey the titanium plate. At the same time, it can increase the service life of the conveyor roller 2, reduce the waste of resources, and is simple to operate and easy to use.
[0039] Any undisclosed portions of the present invention are prior art, and their specific structures, materials, and operating principles will not be described in detail. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
