Description

Technical Field

[0001] This utility model relates to the field of welded pipe processing technology, and in particular to a cutting device with high safety for welded pipe processing. Background Technology

[0002] Welded pipe, an indispensable type of pipe in modern industry, refers to steel pipes with seams on their surface, made by bending steel strips or plates into round, square, or other shapes and then welding them together. Due to its advantages such as light weight, high strength, and low cost, welded pipe is widely used in construction, machinery, automobiles, oil and gas transportation, and many other fields. In the processing of welded pipe, cutting is a crucial step, directly affecting the dimensional accuracy, appearance quality, and subsequent processing efficiency.

[0003] However, existing welded pipe cutting equipment has gradually revealed safety issues during use. In particular, the cutting mechanism generates a large number of sparks during the cutting process, which not only easily pollute the surrounding environment but also may splash onto operators, posing a serious safety hazard. Furthermore, when replacing welded pipes, existing cutting equipment is often still running, exposing workers to a significant risk of injury during the material unloading process.

[0004] Taking the cutting device in a high-frequency welded pipe machine disclosed in application number CN202120255059.0 as an example, although it improves the cutting efficiency of welded pipes to a certain extent, it still has obvious shortcomings in terms of safety performance. The problem of sparks and spatter generated during the cutting process has not been effectively solved, and the operational safety when changing welded pipes is not fully guaranteed.

[0005] Therefore, to address these shortcomings in existing technologies, we urgently need a safer cutting device for welded pipe processing. This cutting device should effectively solve the problem of spark splashing, while ensuring the safety of operators during welded pipe replacement, thus providing strong support for safe production in the welded pipe processing industry.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example 1

[0027] Please see Figure 1-5 As shown, a cutting device with high safety for welded pipe processing according to this embodiment includes a cutting table 1 and a mounting frame 4;

[0028] Cutting table 1: As the basic platform for the entire cutting operation, cutting table 1 provides a stable and flat placement space for the welded pipe.

[0029] Mounting rack 4: Mounting rack 4 adopts a three-sided enclosed structure design, forming a relatively closed working environment. Tempered glass mounting slots 5 are provided on both sides for installing tempered glass, allowing operators to clearly observe the operation within the cutting area. Simultaneously, the tempered glass effectively isolates sparks, protecting the operator's safety.

[0030] Cutting Machine 3: Cutting Machine 3 is the core component for performing the cutting operation. It is connected to the top of Mounting Frame 4 via a lifting module. The lifting module can precisely adjust the height of Cutting Machine 3 to accommodate the cutting needs of welded pipes of different sizes. During the cutting process, Cutting Machine 3 precisely cuts the welded pipe.

[0031] Carrier plate 2: Carrier plate 2 is located at the bottom of the cutting machine 3 and is slidably connected to the top of the cutting table 1. This sliding connection method facilitates the operator to quickly move carrier plate 2 to a safe position when changing welded pipes.

[0032] Clamping Module: The clamping module is connected to the support plate 2 via an adjustable sliding structure to securely clamp the welded pipe at the cutting position. The clamping module includes an adjusting plate 11, two clamps 9, a guide rod 15, and an adjusting screw 14. The adjusting plate 11 can slide along the top of the support plate 2 and is fixed in a specific position by a positioning rod 13. The two clamps 9 are slidably connected by the guide rod 15 and their relative positions are adjusted by the adjusting screw 14 to accommodate welded pipes of different diameters. The V-groove design on the clamps 9 allows them to adapt to welded pipes of different shapes, ensuring that the welded pipe is firmly and evenly clamped.

[0033] The mounting frame 4 has a three-sided covering structure, and both sides of the mounting frame 4 are provided with tempered glass mounting grooves 5 for installing tempered glass. The inside of the mounting frame 4 is equipped with a cutting machine 3, which is connected to the top of the mounting frame 4 through a lifting module.

[0034] The bottom of the cutting machine 3 is provided with a support plate 2 that is slidably connected to the top of the cutting table 1. Both sides of the top of the support plate 2 are connected with clamping modules through an adjustable sliding structure.

[0035] Example 2

[0036] Please see Figure 1-5 As shown in this embodiment, a cutting device with high safety for welded pipe processing is provided. Guide rods 6 are connected to both sides of the top of the cutting table 1. The bearing plate 2 has two round holes inside for sliding cooperation with the guide rods 6. Through the setting of the guide rods 6 and the round holes inside the bearing plate 2, the bearing plate 2 can slide smoothly along the guide rods 6. This sliding connection method makes it easy for the operator to quickly move the bearing plate 2 to a safe position when changing the welded pipe, thus improving work efficiency and safety.

[0037] Limiting grooves 12 are provided at the center of both sides of the support plate 2, and a lifting cylinder 8 is installed at the center of the bottom of the support plate 2. The output end of the lifting cylinder 8 is connected to a limiting frame 7. The limiting frame 7 is U-shaped, and one end of each of the two vertical sections of the limiting frame 7 passes through the support plate 2 and engages with the limiting grooves 12 via sliding sleeves. Specifically, through the arrangement of the limiting grooves 12, the lifting cylinder 8, and the limiting frame 7, the lifting cylinder 8 can drive the limiting frame 7 to move up and down during the cutting process. Through the engagement of the limiting frame 7 with the limiting grooves 12, the support plate 2 is provided with additional support and limitation. This design not only enhances the stability of the support plate 2 during the cutting process, but also ensures that the limiting frame 7 can respond quickly when needed by the precise control of the lifting cylinder 8, thus improving the safety and reliability of the device.

[0038] Example 3

[0039] Please see Figure 1-5 As shown in this embodiment, a high-safety cutting device for welded pipe processing includes a clamping module comprising an adjusting plate 11 and two clamps 9. The two clamps 9 are symmetrically arranged along the vertical direction of the adjusting plate 11, and each clamp 9 has a V-groove on its closest side. Specifically, through the arrangement of the adjusting plate 11, clamps 9, and V-grooves, the clamping module can flexibly adjust to welded pipes of different diameters, ensuring that the welded pipe is firmly clamped in the cutting position. The V-groove design allows the clamps to adapt to welded pipes of different shapes, improving the versatility and clamping stability of the device. During the cutting process, the welded pipe is stably clamped, effectively preventing cutting deviations caused by movement or vibration, and ensuring cutting quality.

[0040] The two clamps 9 are slidably connected on one side by a guide rod 15, and threadedly connected on the other side by an adjusting screw 14. Specifically, the relative position between the two clamps 9 can be easily adjusted by the guide rod 15 and the adjusting screw 14 to accommodate welded pipes of different sizes. The guide rod 15 ensures the stability of the clamps during adjustment, while the adjusting screw 14 provides precise control of the clamping force, allowing the welded pipe to be firmly and evenly clamped. This design not only improves clamping efficiency but also ensures the integrity of the welded pipe during clamping, avoiding deformation or damage to the welded pipe caused by excessive clamping.

[0041] The top two sides of the support plate 2 are provided with sliding grooves 10, and several positioning holes are provided at the center of the top two sides. The bottom two sides of the adjusting plate 11 are fixedly connected with sliders 16 that slide in conjunction with the sliding grooves 10. A positioning rod 13 is provided on the top side of the adjusting plate 11, with one end passing through the adjusting plate 11 via a sliding sleeve and matching the positioning hole. Specifically, through the arrangement of the sliding grooves 10, sliders 16, positioning holes, and positioning rod 13, the adjusting plate 11 can slide along the top of the support plate 2 and be fixed in a specific position as needed. This design allows the clamping module to flexibly adapt to welded pipes of different lengths, while the positioning rod 13 ensures the stability of the adjusting plate in the fixed position, preventing displacement due to vibration during cutting. This flexibility not only improves the adaptability of the device but also ensures the stability and accuracy of the cutting operation.

[0042] This solution includes the following workflow:

[0043] First, the operator places the welded pipe to be cut on the cutting table 1. Through the tempered glass in the tempered glass mounting slots 5 on both sides of the mounting bracket 4, the operator can clearly observe the operation within the cutting area. Then, the cutting device is started, and the cutting machine 3 is precisely adjusted to the required height via the lifting module.

[0044] Next, the operator uses the adjustable sliding structure on the top of the support plate 2, namely the cooperation of the slide groove 10 and the slider 16, to slide the adjusting plate 11 to the appropriate position, and fixes it to the positioning hole on the support plate 2 by passing the positioning rod 13 through the adjusting plate 11. Then, the relative position between the two clamps 9 is adjusted by the guide rod 15 and the adjusting screw 14 on the adjusting plate 11 to adapt to the diameter of the welded pipe, and the welded pipe is firmly clamped in the cutting position by the V-groove.

[0045] Once everything is ready, the cutting machine 3 begins operation, precisely cutting the welded pipe. Throughout the cutting process, thanks to the isolation provided by the mounting bracket 4, the sparks generated during cutting are effectively confined within the cutting area, preventing them from scattering and thus protecting the operating environment and the safety of the operators.

[0046] When a new welded pipe needs to be replaced, the operator first lowers the limiting frame 7 using the lifting cylinder 8 to release the restriction on the support plate 2. Then, the support plate 2 is slid along the guide rod 6 to a position away from the mounting frame 4, so that the welded pipe is away from the cutting station. Next, the clamping module is adjusted to release the clamp on the current welded pipe, and the new welded pipe is placed in place. After being secured again using the clamping module, the support plate 2 is sent back to the bottom position of the cutting machine 3, and the cutting machine 3 is adjusted to an appropriate height. Finally, the lifting cylinder 8 drives the limiting frame 7 to rise, providing additional support and restriction for the support plate 2, and the next cutting operation can begin.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
