Description

Technical Field

[0001] This utility model belongs to the field of steel pipe cutting technology, and in particular relates to a seamless steel pipe cutting device. Background Technology

[0002] In the processing of seamless steel pipes, the cutting operation is a crucial step. When a specific angle of cutting is required, traditional equipment struggles to guarantee the accuracy and consistency of the cut surface. This not only affects subsequent processing steps, such as welding, but also increases production costs and safety risks.

[0003] Specifically, traditional seamless steel pipe cutting devices lack flexibility in cutting angle positioning. Typically, these devices can only achieve single-angle or limited-angle cutting, failing to meet diverse engineering needs. When cutting common angles such as 30°, 45°, or 90° is required, different cutting molds or adjustments to the device structure are often necessary, which is not only time-consuming and labor-intensive but also increases operational difficulty and cost.

[0004] To address the aforementioned problems and improve the efficiency, accuracy, and safety of seamless steel pipe cutting operations, this utility model proposes a novel seamless steel pipe cutting device. Utility Model Content

Detailed Implementation

[0027] 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 scope of protection of the present utility model. Specific Implementation Example 1:

[0029] Please see Figure 1-5 As shown, this utility model is a seamless steel pipe cutting device, including a cutting table 1, a motor 2, a saw blade 3, a pressing assembly 4, and a moving table 5. The cutting table 1 includes an upper worktable surface 11 and a lower worktable surface 12 arranged in parallel. The upper worktable surface 11 and the lower worktable surface 12 are connected and fixed by four fixed columns 13. The moving table 5 is linearly driven to the lower worktable surface 12 by a guide rail screw slider mechanism 6. The motor 2 is mounted on the moving table 5. The saw blade 3 is mounted on the motor 2. The upper worktable surface 11 has a rectangular slot 14 that mates with the saw blade 3. A first steel pipe side baffle 15, a second steel pipe side baffle 16, and a third steel pipe side baffle 17 are fixed on one side of the rectangular slot 14 on the upper surface of the upper worktable surface 11, respectively. The pressing assembly 4 is mounted on the upper surface of the upper worktable surface 11 and is located on the same side as the first steel pipe side baffle 15. These three baffles form fixed angles with the rectangular slot 14. Specifically, the angle between the first steel pipe side baffle 15 and the rectangular slot 14 is 30°, the angle between the second steel pipe side baffle 16 and the rectangular slot 14 is 45°, and the third steel pipe side baffle 17 is perpendicular to the rectangular slot 14 at an angle of 90°. This design allows the seamless steel pipe to be quickly positioned according to the required angle before cutting, improving cutting efficiency and accuracy. The seamless steel pipe cutting device in this embodiment can easily achieve precise cutting at three common angles: 30°, 45°, and 90°, resulting in a smoother and flatter weld surface, higher weld strength, and more reliable weld quality.

[0030] Meanwhile, a steel pipe end stop 18 is fixed on the upper surface of the upper worktable 11 on the other side of the rectangular slot 14. A first positioning slot 19 and a second positioning slot 110 are formed on the side of the steel pipe end stop 18 adjacent to the rectangular slot 14. A first steel pipe side baffle 15 is perpendicular to the first positioning slot 19. A second steel pipe side baffle 16 is perpendicular to the second positioning slot 110. This provides more precise positioning for cutting the steel pipe.

[0031] During the cutting process, the pressing assembly 4 plays a crucial role. This assembly includes a gantry 41 fixed to the upper surface of the upper worktable 11. A double-rod cylinder 42 is mounted on the gantry 41. A pressure plate 43 is mounted on the telescopic end of the double-rod cylinder 42. A rubber layer 44 is fixed to the lower surface of the pressure plate 43 to increase the friction between it and the steel pipe and protect the surface of the steel pipe from damage. Before cutting, the double-rod cylinder 42 pushes the pressure plate 43 down, pressing the seamless steel pipe firmly onto the upper worktable 11 to ensure the stability and accuracy of the cutting.

[0032] Safety and practicality were also considered in the design of the moving table 5. A first arc-shaped baffle 51 and a second arc-shaped baffle 52 are fixed at both ends of the moving table 5 in the direction of movement. These two baffles effectively prevent sparks or debris from flying out during the cutting process, protecting the operator's safety. A support foot 111 is installed at each of the four corners of the lower worktable 12, facilitating the lifting and leveling of the entire device.

[0033] In addition, a steel pipe placement rack 7 is fixed at each end of the cutting table 1 along the length of the rectangular slot 14. The design of these two placement racks is very user-friendly. Each placement rack includes two horizontal crossbars 71 fixed to two fixed columns 13. The free ends of the two horizontal crossbars 71 are connected by L-shaped rods 72 to form a stable structure. An L-shaped plate 73 is also fixed between the two horizontal crossbars 71. A row of short dividing columns 74 is fixed on the L-shaped plate 73 to place and separate the seamless steel pipes, preventing the steel pipes from becoming disordered before and after cutting.
