Description

Technical Field

[0001] This utility model relates to the field of spiral steel pipe cutting technology, and in particular to a cutting device for spiral steel pipe processing with a protective structure. Background Technology

[0002] Spiral welded steel pipe is a type of steel pipe made from strip steel coils, formed by cold extrusion and welded using an automatic double-wire submerged arc welding process. The manufacturing of spiral welded steel pipes generally employs continuous forming and submerged arc welding methods, with two forming methods: internal bearing and external clamping. Due to its mature manufacturing process and low cost, this type of steel pipe has become a major type of steel pipe used for fluid transportation pipelines, widely applied in petrochemical, heating network, and urban water supply and drainage projects. Spiral welded steel pipes and their cutting machines play an important role in pipeline engineering and metal processing, providing high-quality cutting solutions for various engineering constructions.

[0003] In the processing of spiral steel pipes, the use of cutting equipment is crucial. However, for small-diameter spiral steel pipes, effective fixation is required during cutting to ensure accuracy and safety. Currently, one common fixing method is the clamp fixing method.

[0004] The clamp fixing method uses clamps fitted onto the outside of the spiral steel pipe to achieve fixation. While this method can ensure cutting stability to a certain extent, its installation and disassembly process is relatively cumbersome, increasing operational difficulty and time costs. Furthermore, the clamp fixing method performs poorly in continuous cutting operations because it struggles to adapt to the fast and efficient cutting rhythm, impacting production efficiency.

[0005] Another fixing method is to use a clamping mechanism. The clamping mechanism secures the spiral steel pipe by clamping its exterior, thus facilitating cutting. However, this method is prone to problems in practice. For example, improper clamping force may cause the spiral steel pipe to warp during cutting, affecting not only the cutting quality but also potentially creating safety hazards. Furthermore, if the clamping mechanism is poorly designed or improperly operated, the spiral steel pipe may break off during cutting, causing damage to operators and equipment. Utility Model Content

[0006] The main objective of this invention is to provide a cutting device for processing spiral steel pipes with a protective structure, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A cutting device for processing spiral steel pipes with a protective structure, comprising a support table, a conveyor belt, a side bracket, a side support seat, a cutting disc, a driving device and an angle adjustment device. The side bracket and the side support seat are installed at the lower end of the support table. A driving device is installed at the upper end of the side support seat. The cutting disc is connected to the driving device and driven by it. The angle adjustment device is installed on the side bracket and connected to the driving device. The cutting disc is moved down by the angle adjustment device to achieve angle adjustment;

[0009] The upper end of the support table is equipped with a first electric push rod and a second electric push rod. The telescopic ends of the first electric push rod and the second electric push rod are connected with a first pressing seat. The first pressing seat is installed on the support table through a slide rail. A second pressing seat adapted to the first pressing seat is installed on the support table. A clamping cavity is formed between the first pressing seat and the second pressing seat, and the spiral steel pipe is clamped by driving the first pressing seat to move through the electric push rod;

[0010] A socket part is connected to the first pressing seat. A protective straight bar is connected to the socket part through an adjusting screw rod. The side end of the protective straight bar is connected with a protective arc plate through an adjusting distance screw rod. Buffer strips are arranged at the lower ends of the protective arc plate and the protective straight bar. The spiral steel pipe is prevented from tilting up and bursting out through the protective straight bar, the protective arc plate and the buffer strips.

[0011] Among them, the first electric push rod and the second electric push rod are fixed on the support table by bolts. The first electric push rod and the second electric push rod are designed in parallel. The first pressing seat is connected to the first electric push rod or the second electric push rod through a threaded pipe. The slide rail is fixed on the support table by bolts. The slide rail is connected to the first pressing seat through a sliding seat to make it move linearly;

[0012] Among them, the cross-sections of the first pressing seat and the second pressing seat are designed in an "L" shape, and anti-slip rubber gaskets are connected to the inner walls of the first pressing seat and the second pressing seat through adhesives;

[0013] Among them, the clamping cavity faces the conveyor belt, and the cutting disc is located between the first electric push rod and the second electric push rod;

[0014] Among them, the socket part includes a hoop and a screw pipe. The screw pipe is located on the side wall of the hoop. The hoop is fixed on the first pressing seat. The screw pipe is threadedly connected with the adjusting screw rod, and the adjusting screw rod is fixed to the protective straight bar by bolts;

[0015] Among them, the protective arc plate and the adjusting distance screw rod are integrally designed. The adjusting distance screw rod is connected to the protective straight bar through threads. The telescopic movement of the adjusting distance screw rod drives the protective arc plate to cover the clamping cavity;

[0016] Among them, the cross-sections of the protective straight bar and the protective arc plate are designed in a "丿" shape, and the buffer strips are fixed to the protective straight bar and the protective arc plate through adhesives.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The extension and retraction of the first and second electric push rods drive the first clamping seat to move along the slide rail, forming a clamping cavity with the second clamping seat, thus achieving stable clamping of spiral steel pipes of different diameters. The anti-slip rubber pads on the inner wall of the clamping seat increase the friction with the spiral steel pipe, further ensuring the stability of the clamping and providing a solid foundation for cutting operations.

[0019] The sleeve fitting on the first clamping seat is connected to the protective straight bar via an adjusting screw. The protective straight bar is then connected to the protective arc plate via an adjusting screw, forming a protective structure with adjustable height and distance. The protective straight bar, the protective arc plate, and the buffer strip at their lower ends work together to effectively prevent the spiral steel pipe from warping or popping out during processing, improving processing safety. Furthermore, the buffer strip absorbs the impact force during cutting, protecting the spiral steel pipe from damage. Attached Figure Description

The device mainly consists of a support platform 1, a transmission belt 2, a lateral support 5, a lateral support base 6, a cutting disc 7, a drive device 8, and an angle adjustment device 9. The lateral support 5 and the lateral support base 6 are mounted on the lower end of the support platform 1, while the drive device 8 is mounted on the upper end of the lateral support base 6. The cutting disc 7 is connected to the drive device 8 and operates under its drive. The angle adjustment device 9 is mounted on the lateral support 5 and connected to the drive device 8. Through the action of the angle adjustment device 9, the cutting disc 7 can be moved downwards, thereby achieving precise adjustment of the cutting angle.

[0028] At the upper end of the support platform 1, a first electric push rod 3 and a second electric push rod 4 are installed. The telescopic ends of these two electric push rods are connected to a first clamping seat 11, which is mounted on the support platform 1 via a slide rail 10. Furthermore, a second clamping seat 12, adapted to the first clamping seat 11, is also installed on the support platform 1, forming a clamping cavity 13 between the first clamping seat 11 and the second clamping seat 12. The movement of the electric push rods can move the first clamping seat 11, thereby achieving the clamping function of the spiral steel pipe.

[0029] A sleeve 14 is connected to the first clamping seat 11, and the sleeve 14 is connected to the protective straight bar 16 via an adjusting screw 15. The side end of the protective straight bar 16 is connected to the protective arc plate 17 via an adjusting screw 18. Both the lower end of the protective arc plate 17 and the protective straight bar 16 are provided with buffer strips 19. Through the combination of these protective straight bars 16, protective arc plates 17, and buffer strips 19, the spiral steel pipe can be effectively prevented from warping or popping out during processing, thereby improving the safety and stability of processing.

[0030] The first electric push rod 3 and the second electric push rod 4 are bolted to the support platform 1 and are designed as parallel structures. The first abutment 11 is connected to the first electric push rod 3 or the second electric push rod 4 through a threaded tube. The slide rail 10 is bolted to the support platform 1 and connected to the first abutment 11 through a slide block to ensure linear movement.

[0031] The first clamping seat 11 and the second clamping seat 12 are designed with an "L" shape in cross-section to accommodate spiral steel pipes of different diameters. The inner walls of these two clamping seats are connected with anti-slip rubber pads by adhesive to increase the friction between them and the spiral steel pipe, ensuring the stability of the clamping.

[0032] The clamping cavity 13 is directly opposite the transmission belt 2, ensuring that the cutting disc 7 is located between the first electric push rod 3 and the second electric push rod 4, which facilitates precise cutting of the spiral steel pipe.

[0033] The socket part 14 includes a ferrule and a nipple, where the nipple is located on the side wall of the ferrule. The ferrule is fixed on the first abutting seat 11, and the nipple is threadedly connected to the height adjustment screw rod 15. The height adjustment screw rod 15 is fixed to the protection straight bar 16 by bolts, enabling the protection straight bar 16 to be height-adjusted to accommodate spiral steel pipes of different lengths.

[0034] The protection arc plate 17 and the distance adjustment screw rod 18 are integrally designed. The distance adjustment screw rod 18 is threadedly connected to the protection straight bar 16. The telescopic movement of the distance adjustment screw rod 18 can drive the protection arc plate 17 to move, thus covering the clamping cavity 13 and providing all-round protection for the spiral steel pipe.

[0035] The cross-sections of the protection straight bar 16 and the protection arc plate 17 are designed as a "丿" shape to enhance the strength and stability of the structure. The buffer strip 19 is fixed to the protection straight bar 16 and the protection arc plate 17 by an adhesive to absorb the impact force during the cutting process and protect the spiral steel pipe from damage.

[0036] Ensure that all components are correctly installed and fixed in place. Check whether the electric push rod is fixed to the support table 1 by bolts and confirm its parallel structure. Use the angle adjustment device 9 to adjust the angle of the cutting disc 7 to adapt to the required cutting angle. Ensure that the cutting disc 7 is connected to the driving device 8 and operates through the drive of the driving device 8. Place the spiral steel pipe in the clamping cavity 13 and ensure that it is directly facing the conveyor belt 2. Through the movement of the first electric push rod 3 and the second electric push rod 4, drive the first abutting seat 11 to move and clamp the spiral steel pipe. Confirm that the anti-slip rubber gaskets on the inner walls of the first abutting seat 11 and the second abutting seat 12 are in contact with the spiral steel pipe to increase the friction force.

[0037] Use the height adjustment screw rod 15 to adjust the height of the protection straight bar 16 to adapt to spiral steel pipes of different lengths. Through the telescopic movement of the distance adjustment screw rod 18, adjust the position of the protection arc plate 17 to ensure that it can cover the clamping cavity 13. Start the conveyor belt 2 and ensure that the conveyor belt 2 is running normally. Drive the cutting disc 7 to perform cutting operations through the driving device 8. Monitor the cutting process to ensure that the spiral steel pipe is cut stably and safely. Confirm that the combination of the protection straight bar 16, the protection arc plate 17 and the buffer strip 19 can effectively prevent the spiral steel pipe from warping or popping out during the processing. Check whether the buffer strip 19 is firmly fixed to the protection straight bar 16 and the protection arc plate 17 to absorb the impact force during the cutting process. After the cutting is completed, turn off the conveyor belt 2 and the driving device 8. Loosen the first abutting seat 11 and take out the cut spiral steel pipe. Clean the equipment and prepare for the next cutting operation.
