Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically a segmented heating device for hot-rolled wire rod. Background Technology

[0002] In the processing of hot-rolled wire rod, the heating furnace is a key piece of equipment to ensure the heating quality of the steel billet. During the rolling process, it heats the steel billet in a gradient manner through a preheating section, a heating section, and a soaking section to meet the requirements of subsequent rolling processes for temperature uniformity and material properties.

[0003] In the segmented heating process, steel billets are conveyed through multiple induction heating furnaces via roller conveyors. However, this method requires the roller conveyors to be perfectly aligned. After a period of use, the rollers will break due to contact with the oxide layer on the surface of the steel billets, affecting the conveying stability of the steel billets and making them prone to scraping against the inlet and outlet of the induction furnaces, causing damage or production accidents. At present, the rollers are often maintained by stopping the machine for cleaning, which not only affects production efficiency, but also makes it easy to cause inaccurate positioning when disassembled and reinstalled, affecting the conveying stability. In view of this, this case was developed after in-depth research on the above problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides an implementation scheme: hot-rolled steel billets are conveyed through multiple induction heating furnaces via roller conveyors. However, in the application of this method, the height of the roller conveyor needs to be aligned. After a period of use, the rollers will be damaged due to contact with the oxide layer on the surface of the steel billet, affecting the conveying stability of the steel billet and easily scraping the inlet and outlet of the induction furnace, causing damage or production accidents. At present, the rollers are often maintained by stopping the machine for cleaning, which not only affects production efficiency, but also makes it easy to cause inaccurate positioning when disassembled and reinstalled, affecting the conveying stability.

[0022] To address the aforementioned issues, this application discloses a segmented heating device for hot-rolled wire rod, comprising a support frame 1. The support frame 1 is a rectangular frame structure that provides a stable support foundation for the entire device. Several induction furnaces 2 are arranged in a linear array on the support frame 1 for segmented heating of the hot-rolled wire rod. Several conveying rollers 3 are arranged between the induction furnaces 2 to transport the wire rod between the furnaces.

[0023] A conveyor motor 4 is installed on one side of the support frame 1 to provide conveying power. The drive end of the conveyor motor 4 is connected to a reducer 5 to reduce the speed and increase the output torque. The output end of the reducer 5 is connected to a drive shaft 6, which serves as the main power transmission shaft. Several power distributors are installed on the drive shaft 6 corresponding to several conveyor rollers 3 to distribute and transmit the power of the drive shaft 6 to each conveyor roller 3. The power distributors are connected to the central shaft of the conveyor rollers 3 through a universal coupling 7. This connection method allows for a certain deviation or adjustment in the height of the conveyor rollers 3, while still reliably transmitting torque, ensuring smooth drive even if the roller heights are not completely consistent.

[0024] The conveyor roller 3 is separately mounted on the support frame 1 via the roller seat 8, facilitating independent disassembly and maintenance of each roller. A pair of positioning alignment devices are installed on the support frame 1 at positions corresponding to the roller seat 8, providing a precise positioning reference during installation. The roller seat 8 has a pair of alignment holes 9 that engage with the positioning alignment devices. Through the engagement of these positioning alignment devices and the alignment holes 9, it is ensured that the roller seat 8 and the conveyor roller 3 on it quickly and accurately return to the preset height and centering position during installation, guaranteeing conveying stability.

[0025] A cleaner 10 is installed on one side of the wheel seat 8 on the support frame 1. It is used to clean the oxide layer attached to the surface of the conveyor roller 3 online. The cleaner 10 is set corresponding to the conveyor roller 3. The cleaning angle of the cleaner 10 is in contact with the outer surface of the conveyor roller 3. When the conveyor roller 3 rotates, it continuously scrapes off the oxide scale accumulated on its surface to prevent the oxide layer from accelerating the wear of the roller and affecting the smoothness of the conveying.

[0026] As a preferred embodiment, the cleaner 10 is further provided with a linear screw module 11 mounted on the support frame 1 at its bottom. The cleaner 10 is an inclined rectangular plate with a tapered cleaning angle at the end corresponding to the conveyor roller 3. The linear screw module 11 can drive the cleaner 10 to move or adjust its position precisely along the axial direction of the conveyor roller 3, ensuring that the cleaning angle always maintains the best contact with the roller surface. The tapered cleaning angle design can more effectively scrape off the oxide scale on the roller surface and guide it away from the roller.

[0027] As a preferred embodiment, the power diverter further includes a diverter housing 12, which is fitted over the drive shaft 6. The drive shaft 6 is located inside the diverter housing and has a drive worm gear 13. A drive worm wheel 14 is meshed on one side of the drive worm gear 13. A transfer shaft 15 is connected to the drive worm wheel 14. The end of the transfer shaft 15 is connected to the central shaft of the conveyor roller 3 via a universal coupling 7. The power diverter adopts a worm gear transmission structure. The drive worm gear 13 on the drive shaft 6 drives the drive worm wheel 14 to rotate, changing the power direction by 90 degrees and outputting it through the transfer shaft 15. The output is then transmitted to the conveyor roller 3 via the universal coupling 7. This structure has a compact layout, a large transmission ratio, and a self-locking characteristic, enabling reliable power transmission to the roller within a limited space.

[0028] As a preferred option, the positioning and centering device further comprises a telescopic rod 16 perpendicular to the top surface of the support frame 1, a guide spring 17 assembled inside the telescopic rod 16, and a tapered guide head 18 installed at the head end of the telescopic rod 16. The alignment hole 9 corresponds to the tapered guide head 18. The working principle of the positioning and centering device is as follows: When installing the wheel seat 8, the wheel seat 8 moves downward, and the alignment hole 9 on the wheel seat 8 first contacts the tapered surface of the tapered guide head 18, and automatically centers under the guidance of the tapered surface; the wheel seat 8 continues to be pressed down to overcome the preload of the guide spring 17, causing the telescopic rod 16 to retract until the wheel seat 8 is fully in place. At this time, the tapered guide head 18 is precisely embedded in the alignment hole 9, providing a stable positioning and holding force under the action of the spring force, ensuring the installation height and centering accuracy.

[0029] As a preferred option, a discharge trough is further provided in the center of the cleaning corner. The discharge trough is used to collect and guide the oxide scale debris scraped off by the cleaning corner, preventing it from accumulating near the cleaning corner and affecting the cleaning effect or causing secondary pollution, and keeping the cleaning area unobstructed.

[0030] Workflow Summary: Hot-rolled wire rod is driven by conveyor rollers 3 and sequentially heated in sections by an array of induction furnaces 2. Conveyor motor 4 drives drive shaft 6 to rotate via reducer 5. A power distributor (worm gear driven worm wheel 14) on drive shaft 6 transmits power to each conveyor roller 3 via split shaft 15 and universal coupling 7. As the conveyor rollers 3 rotate and convey the wire rod, oxide scale adheres to their surface. A cleaner 10 installed on the side of the rollers, with its cleaning angle closely fitting the outer surface of the rollers, continuously scrapes off the oxide scale during roller rotation. The scraped debris is then transported through... The material is discharged through the discharge chute at the center of the cleaning corner. The linear screw module 11 at the bottom of the cleaner 10 can adjust the axial position of the cleaner 10 to maintain the best cleaning effect. When a certain conveying roller 3 needs maintenance or replacement, only the corresponding wheel seat 8 of the roller needs to be removed. After maintenance, the wheel seat 8 is put back into the corresponding position of the support frame 1. The alignment hole 9 on the wheel seat 8 is automatically and accurately aligned and locked under the guidance of the positioning centering device (the conical guide head 18 under the action of the spring), ensuring that the roller is restored to the correct height and alignment state. There is no need to stop the whole machine and the installation and positioning are accurate and reliable.

[0031] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
