Description

Technical Field

[0001] This utility model belongs to the field of hot-rolled steel pipe processing technology, specifically a production and processing equipment for hot-rolled steel pipes. Background Technology

[0002] Hot-rolled steel pipe is a type of steel pipe produced through a hot rolling process. The production principle involves heating a steel billet to a high temperature, placing it in an austenitic state, and then applying pressure through the rolls of a rolling mill to cause plastic deformation of the billet, ultimately forming a tubular steel product with a hollow cross-section and no seams around its perimeter. The processing of hot-rolled steel pipe includes cutting, which aims to cut long steel pipes to specified lengths, such as 6 meters or 12 meters, to facilitate transportation and subsequent use.

[0003] However, the following problems were found in the implementation of the relevant technologies:

[0004] In the steel pipe clamping stage, existing hot-rolled steel pipe cutting devices mostly use fixed clamps or manually adjustable clamping structures. Fixed clamps are difficult to adapt to steel pipes of different diameters. When the steel pipe diameter does not match the clamp specifications, the clamping is prone to insecure, causing the steel pipe to shake during the cutting process, which seriously affects the cutting accuracy and processing quality. On the other hand, manually adjustable clamping structures are not only cumbersome and time-consuming to operate, making it difficult to meet the needs of high-efficiency production, but also have limited adjustment accuracy, making it difficult to achieve precise clamping, which also reduces the accuracy and stability of cutting.

[0005] Furthermore, in terms of cutting control, existing devices typically cannot flexibly adjust the position of the cutting disc and the steel pipe. The cutting position is fixed or inconvenient to adjust, making it difficult to adapt to diverse cutting needs and limiting the application scenarios of the equipment. At the same time, the cutting power system is inefficient, and the cutting disc speed is unstable, resulting in low cutting efficiency and poor cut quality. In addition, the lack of an effective guiding structure means that during the cutting process, the support that carries the cutting disc is prone to shifting due to vibration or uneven force, causing deviations in the cutting position. This not only affects the cutting accuracy but also increases the risk of equipment failure and shortens the equipment's service life. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a production and processing equipment for hot-rolled steel pipes, which features efficient clamping and precise cutting. By using a servo motor to drive a bidirectional lead screw and alternating clamping arc rods, the problems of unstable clamping and poor adaptability in existing devices are solved. Furthermore, by using an electric push rod, a DC motor, and a guide frame and positioning rod, the problems of inconvenient cutting position adjustment, low efficiency, and poor precision are resolved.

[0009] Preferably, a protective slanted frame is fixedly provided on the side of the upper surface of the table away from the cutting disc.

[0010] Preferably, a waste bin is provided on the underside of the tabletop, and limiting plates are symmetrically fixed on the lower surface of the tabletop, with the waste bin positioned between the two limiting plates.

[0023] 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.

[0024] like Figures 1 to 4As shown, this utility model provides a production and processing equipment for hot-rolled steel pipes, including a table 1. A drive pipe 2 is symmetrically fixed on the upper surface of the table 1, and a clamping arc rod 3 is provided on the upper side of the drive pipe 2. A bracket 4 is provided on one side of the table 1, and a cutting disc 44 is provided on one side of the bracket 4. A bidirectional lead screw 21 is rotatably installed inside the drive pipe 2. A servo motor 22 is fixed on one side of the drive pipe 2, and the output end of the servo motor 22 passes through the drive pipe 2 and is fixedly connected to the bidirectional lead screw 21. Moving blocks 23 are symmetrically threaded on the outer surface of the bidirectional lead screw 21. Sleeve blocks 24 are fixedly installed on both sides of the moving blocks 23. A vertical plate 2 is bolted to the upper surface of the sleeve blocks 24. 5. The inner side of the upright plate 25 is detachably provided with an installation plate 26. The inner side of the installation plate 26 is fixedly connected to the corresponding clamping arc rod 3. When the servo motor 22 is started, it drives the bidirectional lead screw 21 to rotate. Since the outer surface of the bidirectional lead screw 21 is symmetrically threaded with moving blocks 23, under the action of thread transmission, the two moving blocks 23 move towards or away from each other along the bidirectional lead screw 21, thereby driving the sleeve block 24 to move. The sleeve block 24 drives the clamping arc rod 3 to move through the upright plate 25 and the installation plate 26. There are three clamping arc rods 3 on one side of one of the driving pipes 2, which are alternately distributed on both sides, so as to stably clamp and fix the hot-rolled steel pipe and adapt to the clamping requirements of steel pipes of different diameters.

[0025] Specifically, a side support plate 41 is fixedly provided on the lower surface of the tabletop 1, and a vertical block 47 is fixedly provided on the upper surface of the side support plate 41. An electric push rod 42 is fixedly provided on the inner side of the vertical block 47, and the output end of the electric push rod 42 is fixedly connected to the bracket 4. A DC motor 43 is fixedly provided on the upper surface of the bracket 4, and the output end of the DC motor 43 is fixedly connected to the cutting disc 44. When the electric push rod 42 is started, it pushes the bracket 4 to move along the guide direction of the guide frame 45 and the positioning rod 46, so that the cutting disc 44 is close to the hot-rolled steel pipe to be cut. When the DC motor 43 is started, it drives the cutting disc 44 to rotate at high speed to cut the clamped and fixed hot-rolled steel pipe.

[0026] Furthermore, a protective bevel frame 6 is fixedly provided on the side of the upper surface of the table 1 away from the cutting disc 44. During the cutting process, the protective bevel frame 6 can prevent the debris generated during cutting from flying, thus protecting the operator and the surrounding environment.

[0027] Furthermore, a waste bin 7 is provided on the underside of the tabletop 1, and limiting plates 71 are symmetrically fixed on the lower surface of the tabletop 1. The waste bin 7 is positioned between the two limiting plates 71. The waste generated during cutting falls below the tabletop 1. Since the waste bin 7 is located on the underside of the tabletop 1 and is positioned between the two limiting plates 71, the waste can fall directly into the waste bin 7, making it convenient for centralized collection and processing.

[0028] It is worth noting that there are three clamping arc rods 3 on one side of one of the drive tubes 2, and the clamping arc rods 3 on both sides are alternately distributed, which can stably clamp and fix the hot-rolled steel pipe and adapt to the clamping requirements of steel pipes of different diameters.

[0029] It is worth noting that the sleeve 24 is symmetrically fixed with slide bars 27, and the slide bars 27 are locked on the corresponding drive tube 2. At the same time, the slide bars 27 inside the sleeve 24 are locked on the drive tube 2 to ensure the stability and guidance of the movement of the sleeve 24.

[0030] It is worth mentioning that the mounting plate 26 is symmetrically fixed with a plug rod 28 on one side, and the plug rod 28 is inserted into the corresponding upright plate 25. The plug rod 28 and the corresponding upright plate 25 are connected by bolts, which makes the clamping mechanism easy to disassemble and can be used for different models of hot-rolled steel pipes.

[0031] It is worth emphasizing that a guide frame 45 is fixedly provided on the inner side of the side support plate 41, and a positioning rod 46 is fixedly provided on the lower surface of the bracket 4. The lower end of the positioning rod 46 is movably inserted into the guide frame 45, which improves the stability of the movement of the bracket 4.

[0032] Among them, the servo motor 22, electric push rod 42, and DC motor 43 are all existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0033] Working principle: The servo motor 22 starts and drives the bidirectional lead screw 21 to rotate. Since the outer surface of the bidirectional lead screw 21 is symmetrically threaded with moving blocks 23, under the action of thread transmission, the two moving blocks 23 move towards or away from each other along the bidirectional lead screw 21, thereby driving the sleeve block 24 to move. The sleeve block 24 drives the clamping arc rod 3 to move through the vertical plate 25 and the mounting plate 26. There are three clamping arc rods 3 on one side of one of the driving tubes 2, which are alternately distributed on both sides, so as to stably clamp and fix the hot-rolled steel pipe and adapt to the clamping requirements of steel pipes of different diameters. At the same time, the slide bar 27 inside the sleeve block 24 is locked on the driving tube 2 to ensure the stability and guidance of the movement of the sleeve block 24.

[0034] When the electric push rod 42 is started, it pushes the bracket 4 to move along the guide direction of the guide frame 45 and the positioning rod 46, so that the cutting disc 44 is close to the hot-rolled steel pipe to be cut. When the DC motor 43 is started, it drives the cutting disc 44 to rotate at high speed and cuts the clamped and fixed hot-rolled steel pipe. During the cutting process, the protective inclined frame 6 can prevent the debris generated during cutting from flying, thus protecting the operator and the surrounding environment.

[0035] The waste generated during cutting falls below the table 1. Since the table 1 has a waste bin 7 on its underside and is secured between two limiting plates 71, the waste can fall directly into the waste bin 7, making it easy to collect and process.
