Description

Technical Field

[0001] This utility model relates to the field of round tube quenching technology, specifically a round tube quenching device for ferrous metal smelting and rolling products. Background Technology

[0002] Ferrous metals generally include round tubes, and quenching equipment is used in the processing and production of round tubes to heat the outer wall of the round tube.

[0003] The quenching device consists of a quenching cylinder and internal fixing components. The fixing components clamp and fix the round tube. To ensure the quenching quality of the round tube, multiple sets of fixing components are generally connected by connecting plates. Then, the connecting plates drive multiple sets of round tubes to rotate inside the quenching cylinder, thereby enabling comprehensive quenching of the outer circumference of the round tube. However, since the round tube is usually fixed by external clamping during the quenching process, the outer wall of the round tube will be obstructed, resulting in poor quenching effect on the obstructed part of the round tube. At the same time, it is not convenient to adjust according to the size and length of the round tube, reducing the fixing effect during the quenching process and making it inconvenient to use. To address the shortcomings of the existing technology, we propose a round tube quenching device for ferrous metal smelting and rolling to solve the above problems. Utility Model Content

Multiple sets of the front inner support plate array are installed on the outer peripheral wall of the installation cylinder. The front inner support plate and the rear inner support plate are connected by a connecting component. The front inner support plate and the rear inner support plate respectively perform fixing operations on both ends of the circular tube.

[0006] Preferably, a first motor is installed on the outer wall of the quenching cylinder, and the output end of the first motor is fixedly connected to the outer wall of the drive plate. The operation of the first motor causes the drive plate to drive multiple sets of fixed components to rotate.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model discloses a quenching device for round tubes used in ferrous metal smelting and rolling.

[0026] According to the appendix Figure 1-7As shown, the device includes a quenching cylinder 1, a sealing cover 2 at the front end of the quenching cylinder 1, and a fixing assembly 3 inside the quenching cylinder 1. Multiple sets of fixing assemblies 3 are connected by a drive plate 4. The drive plate 4 drives the multiple sets of fixing assemblies 3 to rotate inside the quenching cylinder 1. The fixing assemblies 3 are connected to the drive plate 4 through connecting plates 402. The connecting plates 402 drive the fixing assemblies 3 to rotate. In use, the sealing cover 2 is opened, and the round tubes to be quenched are first supported and fixed by the multiple sets of fixing assemblies 3. Then the sealing cover 2 is closed, and the first motor 401 on one side is started, so that the first motor 401 and the drive plate 4 together drive the multiple sets of fixed round tubes to rotate inside the quenching cylinder 1. At the same time, the third motor 3037 is started, so that the multiple sets of connecting plates 402 drive the fixed round tubes to rotate on the outer wall of the connecting plates 402, thereby enabling comprehensive quenching of the outer walls of the multiple sets of round tubes.

[0027] The fixing component 3 is a combination of a fixing element and a driving component. The fixing element includes a front inner support plate 301 and a rear inner support plate 302 located at both ends inside the quenching cylinder 1. The inner wall of the connecting plate 402 is fixedly connected to the mounting cylinder 303. The driving component is installed inside the mounting cylinder 303. Multiple sets of front inner support plates 301 are arrayed and installed on the outer peripheral wall of the mounting cylinder 303. The front inner support plates 301 and the rear inner support plates 302 are connected by a connecting element. The front inner support plates 301 and the rear inner support plates 302 fix the two ends of the round tube respectively. When fixing the round tube with the fixing component 3, the distance between the front inner support plates 301 and the rear inner support plates 302 on both sides is adjusted according to the length of the quenching round tube, so that the front inner support plates 301 and the rear inner support plates 302 on both sides can support and fix the two ends of the round tube, thereby improving the fixing effect of the round tube.

[0028] A first motor 401 is installed on the outer wall of the quenching cylinder 1. The output end of the first motor 401 is fixedly connected to the outer wall of the drive plate 4. The operation of the first motor 401 causes the drive plate 4 to drive multiple sets of fixed components 3 to rotate. Multiple sets of third motors 3037 are installed on the inner wall of the drive plate 4. The output end of the third motor 3037 is fixedly connected to the connecting plate 402. When fixing the round tube, firstly, according to the length of the round tube, the worker pulls outwards multiple sets of rear inner support plates 302. At this time, the telescopic rods 3021 at the rear inner support plates 302 can be slidably connected to the inside of the telescopic sleeve 3022, so that the distance between the front inner support plates 301 and the rear inner support plates 302 on both sides after adjustment corresponds to the length of the round tube. At this time, the multiple sets of front inner support plates 301 and rear inner support plates 302 are in a close-to-each-other state. Then, the round tube is sleeved on the outer peripheral wall of the multiple sets of front inner support plates 301 and rear inner support plates 302. By starting the second motor 3036 inside the mounting cylinder 303, The second motor 3036 drives the drive sleeve 3031 to rotate inside the mounting cylinder 303. Through the meshing between the drive sleeve 3031 and multiple sets of drive gears 3032, and the meshing between the multiple sets of drive gears 3032 and the transmission racks 3033, multiple sets of transmission racks 3033 can simultaneously slide on the outer wall of the drive sleeve 3031, causing multiple sets of transmission racks 3033 to simultaneously drive multiple sets of front inner support plates 301 to slide away from each other, thereby enabling multiple sets of front inner support plates 301 to support the inner circumferential wall of the round tube. Through the connecting piece, multiple rear inner support plates 302 are connected to the front inner support plates 301, thereby enabling the rear inner support plates 302 to support the other end of the round tube, thus enabling the inner support and fixation of the two ends of round tubes of different sizes. Then, under the action of the third motor 3037, the fixed round tubes can be driven to rotate inside the quenching cylinder 1, enabling the round tubes to rotate independently, thereby realizing the quenching operation of the outer circumferential wall of the round tube.

[0029] A fixing plate 3035 is fixedly installed in the center of the mounting cylinder 303. The driving assembly includes a driving gear sleeve 3031, a driving gear 3032, a transmission rack 3033, a limiting plate 3034, and a second motor 3036. The driving gear sleeve 3031 and the second motor 3036 are located on both sides of the fixing plate 3035. The output end of the second motor 3036 is fixedly connected to the driving gear sleeve 3031. The fixing assembly 3 is connected to the third motor 3037 through multiple sets of connecting plates 402, and the third motor 3037 is connected to the first motor 401 through a set of driving plates 4, thereby enabling the first motor 401 to drive multiple sets of gears simultaneously. The round tubes rotate inside the quenching cylinder 1, and can be driven by multiple sets of third motors 3037 to rotate on the outer wall of the drive plate 4, so that the outer peripheral walls of the multiple sets of round tubes can contact the inner peripheral wall of the quenching cylinder 1, thereby improving the quenching quality of the outer peripheral wall of the round tubes. At the same time, the fixing component 3 fixes and holds the round tubes in the form of internal support. Compared with the external clamping and fixing method, the internal support clamping and fixing method does not obstruct the outer peripheral wall of the round tubes, and can fully make the outer peripheral wall of the round tubes contact the inner peripheral wall of the quenching cylinder 1, thereby further improving the quenching quality of the round tubes and ensuring the quenching effect.

[0030] Multiple sets of drive gears 3032 are distributed on the inner peripheral wall of drive sleeve 3031 and mesh with each other. Transmission rack 3033 is located on one side of drive gear 3032 and meshes with each other. Transmission rack 3033 is located on one side of drive sleeve 3031. One end of multiple sets of transmission racks 3033 passes through mounting cylinder 303 and is fixedly connected to the inner wall of front inner support plate 301. Limiting plate 3034 is fixedly connected to the other end of transmission rack 3033.

[0031] The connector includes a telescopic rod 3021 and a telescopic sleeve 3022. The ends of the telescopic rod 3021 and the telescopic sleeve 3022 that are far apart from each other are fixedly connected to the front inner support plate 301 and the rear inner support plate 302, respectively. The telescopic rod 3021 is slidably connected inside the telescopic sleeve 3022.
