Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1, by Figures 1 to 7 The present invention comprises a feeding rack 1, a V-shaped material belt conveying module 2 for supporting and actively transferring a stainless steel pipe workpiece in the X-axis direction is installed on the top of the feeding rack 1, and a bevel gear driving unit 3 for driving the V-shaped material belt conveying module 2 to work is arranged above the feeding rack 1; An X-axis distance adjustment mechanism 4 is arranged on one side of the top of the V-shaped material belt conveying module 2, and a pressure wheel type steel pipe conveyor 5 for pressing and rolling the stainless steel pipe workpiece is installed at the movable end of the X-axis distance adjustment mechanism 4; Side frame 6, side frame 6 is fixed on one side outer wall of the feeding frame 1 and is located at the discharge end of the V-shaped material belt conveying module 2. A bending pipe assembly 9 is arranged on the outer wall of the side frame 6 away from the feeding frame 1. A lifting cutting assembly 8 for cutting stainless steel pipe workpieces is arranged on the top of the side frame 6 between the bending pipe assembly 9 and the V-shaped material belt conveying module 2. A PLC control panel 7 is installed on one side of the surface of the side frame 6. The output end of the PLC control panel 7 is electrically connected to the input end of the bevel gear drive unit 3, the X-axis spacing adjustment mechanism 4, the pressure wheel type steel pipe conveyor 5, the lifting cutting assembly 8, and the bending pipe assembly 9. The PLC control panel 7 is the control center of the entire equipment and is responsible for monitoring and controlling the operating status of each component. Through pre-set programs and algorithms, the PLC control panel can realize precise control of parameters such as conveying speed, bending angle, cutting length, etc., to ensure the stability and accuracy of the processing process; The V-shaped material belt conveying module 2 includes a plurality of support feet 201 installed on both sides of the top of the feeding frame 1, a first square-mouthed hollow straight beam 202 and a second square-mouthed hollow straight beam 203 respectively fixed on the top of the two support feet 201, and a belt wheel transfer structure 207 installed on the surface of the second square-mouthed hollow straight beam 203 and the first square-mouthed hollow straight beam 202, the relative surface angle between the first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203 is 90 degrees, and the relative sides of the first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203 are integrally formed with ribs 20 4. The ribs 204 make the bottom edges of the first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203 closed, preventing the steel pipe from falling out of the bottom edges of the first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203. The design of the ribs 204 makes the first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203 more stable during the transportation process. By increasing the support at the bottom, vibration and swing can be reduced, ensuring that the steel pipe maintains a stable position and direction during the transportation process, thereby improving the overall stability and reliability of the V-shaped material belt conveying module 2; A right-angled long beam 206 is fixed on the outer wall of the first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203 away from each other. The bevel gear driving unit 3 includes a protective shell 205 fixed on the outer wall of one side of the second square-mouthed hollow straight beam 203, and a stepper motor 301 installed on the top of the protective shell 205.

The pulley transfer structure 207 includes axles rotatably installed at both ends of the first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203, and a synchronous wheel installed on the outer circumference of the axle. The first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203 provide installation space for the axles, synchronous wheels, crawler tracks and other structures in the pulley transfer structure 207, and the side walls of the first square-mouthed hollow straight beam 202 and the second square-mouthed hollow straight beam 203 in a right-angle relationship can support the crawler tracks and steel pipes. The wheel axle is in line with the central axis of one of the bevel gears in the bevel gear right-angle transmission structure 302, and a crawler is installed between the two wheel axles in the same X-axis direction. The PLC control panel 7 controls the stepper motor 301 to work according to the set direction, speed, angle, and response time. The rotary power of the stepper motor 301 is transmitted to two pulley transfer structures 207 in a mirror-symmetrical relationship through the bevel gear right-angle transmission structure 302. At this time, the two pulley transfer structures 207 can synchronously and unidirectionally transport the stainless steel pipe workpiece; Using a single stepper motor 301 to drive the V-belt conveyor module 2 can simplify the equipment design, reduce the number and complexity of components, which not only reduces the cost of the system, but also reduces the possibility of failure, making the equipment layout more compact and suitable for production sites with limited space.

[0020] Embodiment 2, based on embodiment 1, Figure 8 and Fig. 9 It is given that the X-axis distance adjustment mechanism 4 includes a one-way cylinder 401 installed at the top of one of the right-angle long beams 206, a support plate 403 slidably installed on the two right-angle long beams 206, and a right-angle long arm 402 used to connect the top of the piston rod of the one-way cylinder 401 and the end of the support plate 403. Before the steel pipe workpiece is transported, the staff turns on the one-way cylinder 401 through the PLC control panel 7 to work, and the one-way cylinder 401 drives the right-angle long arm 402 and the support plate 403 to move in the X-axis, so as to adjust the position of the pressure wheel type steel pipe conveyor 5 on the right-angle long beam 206; The pressure wheel type steel pipe conveyor 5 comprises a convex vertical plate 501 fixed on the top of two supporting plates 403, a connecting rod deflection mechanism 502 arranged between the two convex vertical plates 501, and a straight swing arm 503 installed at the movable end of the connecting rod deflection mechanism 502, and a pressure wheel active rolling mechanism 504 for pressing the stainless steel pipe workpiece is installed on the outer wall of one side of the straight swing arm 503; After the position debugging of the pressure wheel steel pipe conveyor 5 is completed, the staff will start the connecting rod deflection mechanism 502 through the PLC control panel 7 to operate, and the connecting rod deflection mechanism 502 controls the swing amplitude of the straight swing arm 503, that is, controls the hovering height of the pressure wheel active rolling mechanism 504, so that the pressure wheel active rolling mechanism 504 can apply force to the stainless steel pipe workpiece, and the position and strength can be adjusted as needed to adapt to workpieces of different specifications and weights, so as to achieve precise control and protection of the workpiece; The connecting rod deflection mechanism 502 includes a first cylinder 10 hingedly mounted on the outer wall of one side of one of the convex character vertical plates 501, a main rod 11 rotatably mounted between the two convex character vertical plates 501, and a Y-shaped yoke 12 for connecting the top of the piston rod of the first cylinder 10 and one end of the main rod 11, one end of the Y-shaped yoke 12 is fixedly connected to one end of the main rod 11, and the other end of the Y-shaped yoke 12 and the top of the piston rod of the first cylinder 10 are hinged to each other. The pressure wheel active rolling mechanism 504 includes a second reduction motor 13 mounted on the outer wall of the same side of the straight swing arm 503, a pressure wheel monomer 15, and a belt transmission structure 14 installed at the output end of the second reduction motor 13 for driving the pressure wheel monomer 15 to rotate; When the first cylinder 10 performs the telescopic action, it pulls the main rod 11 to rotate through the Y-shaped yoke 12. Since the straight swing arm 503 is fixed on the main rod 11, the swing amplitude of the straight swing arm 503 and the height of the pressure wheel unit 15 change. When the pressure wheel unit 15 presses the workpiece, the staff turns on the second reduction motor 13 to work, and the second reduction motor 13 drives the pressure wheel unit 15 to rotate through the belt transmission structure 14, so that the workpiece is rolled forward. During this process, the rotation speed of the pressure wheel unit 15 can be adapted to the transfer speed of the V-shaped material belt conveyor module 2.

[0021] Embodiment 3, based on embodiment 1, Fig.11 and Fig.12 It is given that the bending pipe assembly 9 includes a back plate 901 fixed on the outer wall of one side of the side frame 6, an L-shaped bracket 903 slidably mounted on the outer wall of the back plate 901, and a third cylinder 902 installed at the bottom end of the back plate 901 for driving the L-shaped bracket 903 to lift and lower, a convex plate 904 is fixed on the outer wall of the L-shaped bracket 903 away from the back plate 901, a main shaft 905 is rotatably mounted inside the convex plate 904, a first reduction motor 16 for driving the main shaft 905 to rotate is installed at the bottom end of the L-shaped bracket 903, a main clamping plate 908 is installed at the top end of the main shaft 905, a double-layer suspension 906 is fixed on the surface of the main shaft 905, and a steel pipe limiting structure 907 for cooperating with the main clamping plate 908 and clamping the pipe fitting is arranged inside the double-layer suspension 906; The steel pipe limiting structure 907 includes a fourth cylinder 912 installed inside the double-layer suspension 906, a right-angle slide 909 installed at the top of the piston rod of the fourth cylinder 912, and a secondary clamping plate 910 fixed on the outer wall of one side of the right-angle slide 909. A groove 911 is provided between the opposite outer walls of the secondary clamping plate 910 and the main clamping plate 908. The fourth cylinder 912 controls the positions of the right-angle slide 909 and the secondary clamping plate 910, so that the secondary clamping plate 910 is close to the main clamping plate 908 and clamps the steel pipe workpiece to ensure that the steel pipe workpiece is stably stressed and deformed. The cross-sectional shape of the groove 911 can be circular, elliptical or rectangular. When the stainless steel pipe workpiece passes through the pipe bending assembly 9 and waits to be bent, the steel pipe limiting structure 907 applies force to the steel pipe workpiece, so that the stainless steel pipe workpiece is clamped by the main clamping plate 908 and the groove 911 on the outer wall of the steel pipe limiting structure 907. Before the pipe bending assembly 9 bends the steel pipe, the height of the back plate 901, the steel pipe limiting structure 907 and other components can also be controlled by the third cylinder 902, so that the groove 911 and the passing point of the steel pipe workpiece are at the same height; When the stainless steel pipe workpiece is clamped by the PLC control panel 7 and the lifting cutting assembly 8, the first reduction motor 16 drives the main shaft 905, the main clamping plate 908, the double-layer suspension 906 and the steel pipe limiting structure 907 to rotate together. In this process, since the stainless steel pipe workpiece is clamped by the steel pipe limiting structure 907, the stainless steel pipe workpiece will be deformed and bent by force during the rotation of the steel pipe limiting structure 907 and the main clamping plate 908, thereby completing the bending process and sizing of the workpiece. The bending assembly 9 can bend the stainless steel pipe workpiece to meet the processing requirements of various angles and bending radii.

[0022] Embodiment 4, based on embodiment 1, Fig.10 It is given that the lifting and cutting assembly 8 includes a double-rod stand 801 fixed on the top of the side frame 6, a slide 803 slidably installed on one end of the surface of the double-rod stand 801, and a second cylinder 802 installed on the top of the double-rod stand 801 for driving the slide 803 to rise and fall. A cutting machine 804 is installed on the outer wall of one side of the slide 803. The cutting machine 804 includes a motor installed on the outer wall of one side of the slide 803, and a cutting disc installed on the output end of the motor. After completing the bending operation of the steel pipe workpiece, the staff can start the lifting and cutting assembly 8 again through the PLC control panel 7 to work, that is, the cutting machine 804 actively rotates, and the second cylinder 802 controls the slide 803 and the cutting machine 804 to move downward until the cutting machine 804 completes the cutting operation on the steel pipe. It is responsible for cutting the workpiece that has been bent to finally obtain a stainless steel pipe of the required size.

[0023] When the embodiment of the present application is used, the staff first places the long stainless steel pipe workpiece to be bent on the V-shaped material belt conveyor module 2, so that the stainless steel pipe workpiece is supported by the V-shaped material belt conveyor module 2, and then starts the X-axis distance adjustment mechanism 4 and the pressure wheel steel pipe conveyor 5 through the PLC control panel 7 to work. The X-axis distance adjustment mechanism 4 controls the position of the pressure wheel steel pipe conveyor 5 in the X-axis direction and ensures that the position of the pressure wheel steel pipe conveyor 5 is stable. After the action is completed, the pressure wheel steel pipe conveyor 5 actively applies a pressure on the upper surface of the stainless steel pipe workpiece. With rolling forward pressure, when the X-axis distance adjustment mechanism 4 and the pressure wheel steel pipe conveyor 5 are debugged, the staff starts the bevel gear drive unit 3 and the pressure wheel steel pipe conveyor 5 through the PLC control panel 7 to work, and pre-programs the conveying speed, steel pipe bending angle, cutting length and other parameters of the equipment in the PLC control panel 7. Then, the V-shaped material belt conveying module 2 enables the long-specification stainless steel pipe workpiece to be actively supported stably and move forward along the conveying line, and the pressure wheel steel pipe conveyor 5 applies forward pressure on the upper surface of the workpiece through the pressure wheel to ensure the workpiece. The parts will not slide or misalign during the conveying process. When the stainless steel pipe workpiece enters the bending assembly 9, the bending assembly 9 actively applies force to bend the workpiece until the entire stainless steel pipe workpiece is bent into shape. The equipment provides stable support for the stainless steel pipe workpiece through the V-belt conveying module 2, so that it is not easy to shake or slide during the conveying process, thereby ensuring the stability of the conveying. This active support design enables the workpiece to remain stable during the conveying process and is not easy to deform, bend or damage. The pressure wheel steel pipe conveyor 5 applies forward pressure on the upper surface of the workpiece. By adjusting the position and strength of the pressure wheel, the conveying pressure can be accurately controlled. This design can be flexibly adjusted according to the specifications and weights of different workpieces to ensure the stability and protection of the workpiece during the conveying process. It does not need to wait for manual loading, saves production time and labor costs, and makes the production line run more efficiently. By adjusting the working speed of the V-belt conveying module 2 and the bevel gear drive unit 3 and the position of the pressure wheel steel pipe conveyor 5, it can be suitable for stainless steel pipe workpieces of different specifications and weights, thereby improving the general performance of the equipment.
