Description

Technical Field

[0001] This utility model belongs to the field of square and rectangular tube technology, specifically a square and rectangular tube processing and cutting device. Background Technology

[0002] In modern industrial production systems, square and rectangular tubes, with their excellent mechanical properties and processing adaptability, are widely used in key areas such as building steel structures, machinery manufacturing equipment frames, and automobile body frames. Precise cutting of square and rectangular tubes, as a core process in their manufacturing, directly determines the accuracy of subsequent processing and the overall quality of the product, playing a decisive role in production efficiency and cost control.

[0003] Currently, most mainstream square and rectangular tube cutting equipment on the market adopts a single-blade structure. In long-term, high-intensity operation, this traditional cutting method is prone to wear and chipping due to continuous friction between the blade and the metal material. Furthermore, the high temperatures generated during the cutting process accelerate blade wear. Once the blade's performance deteriorates, frequent downtime for replacement is necessary, significantly reducing production efficiency. The frequent manual intervention and equipment maintenance also significantly increase overall production costs. Although some companies have attempted to introduce multi-blade cutting devices, existing multi-blade equipment suffers from poor blade synchronization, complex structure, and high failure rates, making it difficult to achieve efficient collaborative operation between blades. Consequently, it struggles to meet the increasingly stringent production demands of modern industry in terms of cutting precision and stability.

[0004] Therefore, this utility model provides a square and rectangular tube processing and cutting device. Utility Model Content

[0005] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a square and rectangular tube processing and cutting device is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A square and rectangular tube processing and cutting device of this utility model includes a base plate; mounting plates are fixedly installed on both sides of the top of the base plate, a fixing ring is fixedly installed on the top of the mounting plate, and an installation ring is fixedly installed on the inner wall of the fixing ring; feeding mechanisms are provided on both sides of the top of the base plate; a cutting mechanism is provided on the inner wall of the installation ring; a driving mechanism is provided on the top of the surface of the installation ring, a transmission mechanism is provided on the top of the surface of the installation ring; a switching mechanism is provided on the top of the surface of the installation ring; the feeding mechanism includes a support plate, a stepper motor, and a conveying roller; two sets of support plates are provided, and the two sets of support plates are fixedly installed on both sides of the top of the base plate; one side of the top of the support plate is fixedly installed with the stepper motor; the inner wall of the top of the support plate is rotatably installed with the conveying roller; the output end of the stepper motor is fixedly installed with the conveying roller; the coordinated use of the two sets of support plates, the stepper motor, and the conveying roller enables automated feeding and discharging, allowing batch cutting tasks to be completed without much manual intervention, thus improving production efficiency.

[0007] Preferably, the cutting mechanism includes a toothed ring, a shaft frame, a motor, and a cutter. Two sets of toothed rings are rotatably mounted on opposite sides of the inner wall of the mounting ring, with a gap between the two sets for mounting the cutter. The top of the inner wall of the toothed ring is fixedly mounted to the shaft frame. The side of the shaft frame closest to the fixed ring is fixedly mounted to the motor, and the other side of the shaft frame is rotatably mounted to the cutter. The output end of the motor is fixedly mounted to the cutter. In this design, the two sets of toothed rings can rotate through a transmission mechanism, thereby driving the cutter to rotate and cut the rectangular tube. The coordinated use of the shaft frame, motor, and cutter enables the main cutting function, while the alternating cutting by the two sets of cutters reduces blade wear during cutting.

[0008] Preferably, the driving mechanism includes a plate, a servo motor, and a drive shaft. The plate is fixedly mounted on one side of the top of the mounting ring surface. A slot is provided on the top of the mounting ring surface. The servo motor is fixedly mounted on the top of the plate. The output end of the servo motor is fixedly mounted to the drive shaft. In this scheme, the cooperation between the plate and the servo motor can realize the function of driving the drive shaft and provide the main power output for the adjustment of the gear ring. The drive shaft can cooperate with the fixed plate to drive the gear to rotate.

[0009] Preferably, the transmission mechanism includes a fixed long plate, a sliding groove, and a gear. Four sets of fixed long plates are arranged in a ring and fixedly mounted on the surface of the drive shaft. A sliding groove is provided on the surface of the gear, allowing the gear to slide on the surfaces of the drive shaft and the fixed long plates. The gear meshes with two sets of gear rings respectively. In this design, the cooperation between the fixed long plate and the sliding groove allows the gear to rotate normally while also sliding laterally freely, ensuring that the gear can switch between meshing with the gear rings, thereby enabling the drive of a single set of gear rings to rotate.

[0010] Preferably, the switching mechanism includes an L-shaped ring, an electric push rod, a connecting frame, and an arc-shaped plate. The L-shaped ring is fixedly installed on the side of the gear away from the servo motor. The electric push rod is fixedly installed on the top of the fixed ring surface away from the flat plate. The output end of the electric push rod is fixedly installed with the connecting frame. The side of the connecting frame away from the electric push rod is fixedly installed with the arc-shaped plate. The arc-shaped plate is located on the inner wall of the L-shaped ring and is movably installed with the L-shaped ring. In this design, the L-shaped ring can firmly hold the arc-shaped plate in its inner wall to prevent the arc-shaped plate from falling off. The combined use of the electric push rod, the connecting frame, and the arc-shaped plate can push and pull to achieve the automatic back-and-forth sliding of the gear. Through user control, the gear can be engaged and disengaged with different gear rings.

[0011] Preferably, a support structure is provided at the bottom of the inner wall of the fixing ring near the mounting ring; the support structure is used to support the rectangular tube so that it will not tilt due to instability of the center of gravity after cutting. The combined use of the two sets of support structures in this scheme can provide stable support for the rectangular tube when it is cut, so that the rectangular tube always remains parallel to the conveying roller, thereby preventing the rectangular tube from collapsing and tilting, which would prevent the conveying roller from being able to transport it out.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The rectangular tube processing and cutting device of this utility model, through the arrangement of a support plate, a stepper motor, a conveying roller, a toothed ring, a shaft frame, a motor, and a cutter, enables the coordinated use of two sets of support plates, stepper motors, and conveying rollers to achieve automated feeding and discharging. This allows batch cutting tasks to be completed without much manual intervention, improving production efficiency. The two sets of toothed rings can be driven by a transmission mechanism to rotate, thereby driving the cutter to rotate and cut the rectangular tube. The coordinated use of the shaft frame, motor, and cutter enables the main cutting function, while the alternating cutting of the two sets of cutters reduces the degree of blade wear during cutting.

[0014] 2. The square and rectangular tube processing and cutting device of this utility model, through the arrangement of a flat plate, a servo motor, a drive shaft, a fixed long plate, a slide groove, and gears, enables the flat plate and the servo motor to work together to drive the drive shaft and provide the main power output for the adjustment of the gear ring. The drive shaft can work with the fixed long plate to drive the gear to rotate. The fixed long plate and the slide groove can enable the gear to rotate normally and slide laterally at will, ensuring that the gear can switch back and forth to mesh with the gear ring, thereby enabling the single set of gear rings to rotate.

At the top, one side of the top of the support plate 51 is fixedly installed with the stepper motor 52, and the inner wall of the top of the support plate 51 is rotatably installed with the conveyor roller 53. The output end of the stepper motor 52 is fixedly installed with the conveyor roller 53. The cutting mechanism 6 includes a toothed ring 61, a shaft frame 62, a motor 63, and a cutter 64. Two sets of toothed rings 61 are provided, and the two sets of toothed rings 61 are rotatably installed on both sides of the inner wall of the mounting ring 4. A gap is left between the two sets of toothed rings 61 for installing the cutter 64. The top of the inner wall of the toothed ring 61 is fixedly installed with the shaft frame 62. The side of the shaft frame 62 near the fixed ring 3 is fixedly installed with the motor 63, and the other side of the shaft frame 62 is rotatably installed with the cutter 64. The output end of the motor 63 is fixedly installed with the cutter 64. The drive mechanism 7 includes a plate 71, a servo motor 72, and a drive shaft 73. The plate 71 is fixedly mounted on one side of the top surface of the mounting ring 4. A slot is provided on the top of the surface of the mounting ring 4. The servo motor 72 is fixedly mounted on the top of the plate 71, and the output end of the servo motor 72 is fixedly mounted to the drive shaft 73. The transmission mechanism 8 includes a fixed long plate 81, a sliding groove 82, and a gear 83. Four sets of fixed long plates 81 are provided, and the four sets of fixed long plates 81 are fixedly mounted in a ring on the surface of the drive shaft 73. The surface of the gear 83 is provided with a sliding groove 82. The gear 83 is slidably mounted on the surfaces of the drive shaft 73 and the fixed long plate 81 through the opening of the sliding groove 82. The gear 83 respectively engages with two sets of gear rings. The 61-phase meshing switching mechanism 9 includes an L-shaped ring 91, an electric push rod 92, a connecting frame 93, and an arc-shaped plate 94. The L-shaped ring 91 is fixedly installed on the side of the gear 83 away from the servo motor 72. The electric push rod 92 is fixedly installed on the top side of the surface of the fixed ring 3 away from the flat plate 71. The output end of the electric push rod 92 is fixedly installed with the connecting frame 93. The side of the connecting frame 93 away from the electric push rod 92 is fixedly installed with the arc-shaped plate 94. The arc-shaped plate 94 is located on the inner wall of the L-shaped ring 91 and is movably installed with the L-shaped ring 91. A support structure is provided at the bottom of the inner wall of the fixed ring 3 near the mounting ring 4. The support structure is used to support the rectangular tube so that it will not tilt due to instability of the center of gravity after cutting.

[0026] like Figures 1 to 5As shown, the combined use of two sets of support plates 51, stepper motors 52, and conveyor rollers 53 enables automated feeding and discharging, allowing batch cutting tasks to be completed without much manual intervention, thus improving production efficiency. Two sets of gear rings 61 can rotate via the transmission mechanism 8, thereby driving the cutter 64 to rotate and cut the rectangular tube. The combined use of the shaft frame 62, motor 63, and cutter 64 enables the main cutting function. Simultaneously, the alternating cutting of the two sets of cutters 64 reduces blade wear during cutting. The combined use of the plate 71 and servo motor 72 drives the drive shaft 73 and provides the main power output for adjusting the gear rings 61. The drive shaft 73, in conjunction with the fixed long plate 81, drives the gear 83 to rotate. The combination of the 1 and the slide 82 allows the gear 83 to rotate normally while also sliding laterally freely, ensuring that the gear 83 can switch back and forth to mesh with the gear ring 61, thereby driving a single set of gear rings 61 to rotate. The L-shaped ring 91 can firmly hold the arc plate 94 in its inner wall to prevent the arc plate 94 from falling off. The combination of the electric push rod 92, the connecting frame 93 and the arc plate 94 can push and pull to drive the gear 83 to slide back and forth automatically. Through user control, the gear 83 can mesh and separate with different gear rings 61. The combination of the two sets of support structures can provide stable support when the rectangular tube is cut, so that the rectangular tube always remains parallel to the conveying roller 53, thereby preventing the rectangular tube from collapsing and tilting, which would prevent the conveying roller 53 from conveying it out.

[0027] Working principle: During operation, the base plate 1 is first placed on a flat surface. Then, the user places the rectangular tube on top of the conveyor roller 53. The stepper motor 52 is then started to drive the conveyor roller 53 to rotate. As the conveyor roller 53 rotates, it transports the rectangular tube on top to the inner wall of the fixed ring 3, allowing the rectangular tube to move onto the support device on the inner wall of the fixed ring 3. When the cutting position is reached, any set of motors 63 is started to drive the cutter 64 to rotate. Then, the electric push rod 92 is started to push or retract, causing the L-shaped ring 91 to move through the connecting frame 93. When the L-shaped ring 91 moves, it drives the gear 83 to slide on the surface of the fixed long plate 81 until the gear 83 meshes with one of the gear rings 61 and stops. Immediately afterwards, the servo motor 72 is started to drive the drive shaft 73 to rotate. The rotation of the drive shaft 73 drives the gear 83 through the fixed long plate 81. 3. The gear 83 rotates slowly, driving the meshing gear ring 61 to rotate. The rotating gear ring 61 drives the shaft frame 62 to rotate, which in turn drives the cutter 64 to move. When the cutter 64 moves to the bottom of the mounting ring 4, it contacts and cuts the rectangular tube. The cut rectangular tube is then conveyed out of the inner wall of the fixed ring 3 by another set of conveying rollers 53, thus completing the automated cutting. If one set of cutters 64 is damaged or overheats, the user only needs to activate the electric push rod 92 to pull the gear 83 through the connecting frame 93 and the arc plate 94, so that it meshes with the other set of gear rings 61. Then, the servo motor 72 is activated according to the above steps to make the other set of cutters 64 cut the rectangular tube. Through the alternating cutting of the two sets of cutters 64, the uptime of the equipment can be increased, thereby increasing production efficiency.
