Description

Technical Field

[0001] This invention relates to the technical field of pipe bending forming apparatus, and more specifically, to a pipe heating robot and a pipe bending forming system. Background Technology

[0002] Pipes play a vital role in modern industrial production. In pipe bending, pipes are typically processed into straight pipes before being taken to a bending machine for bending. Currently, PVC pipes often require heating before bending, and the existing heating method usually involves heating the outside of the pipe before it is taken to the bending machine for bending.

[0003] This method of heating the pipe before moving it to the pipe bending machine has significant limitations. Heating the entire pipe softens it, making the unbent sections prone to deformation during movement or bending. Furthermore, sometimes pipes with large diameters cannot be bent in one go; the pipe cools down during multiple bends, requiring repeated heating before bending can be completed. This results in low bending efficiency, and repeated heating can also negatively impact the pipe's performance. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as easy deformation of the whole tube during bending and easy cooling of the tube during bending. It provides a tube heating robot and a tube bending system that are not easily deformed during tube bending and bend the tube while heating, thereby improving the tube bending efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A tube heating robot is provided, comprising two sets of heating devices. Each heating device includes a connecting mechanism, an elastic heating mechanism, and a moving mechanism. The two ends of the elastic heating mechanism are respectively connected to the connecting mechanism and the moving mechanism. The controller is communicatively connected to the connecting mechanism, the elastic heating mechanism, and the moving mechanism.

[0006] The pipe-heating robot of this invention, when requiring pipe bending, places the pipe on a bending device, inserts two sets of heating devices into the pipe from both ends, and activates a moving mechanism via a controller to move the heating devices within the pipe. The two sets of heating devices are connected via a connecting mechanism, and the position of the elastic heating mechanism is adjusted so that it is positioned at the desired bending point. The two sets of heating devices are positioned on either side of the desired bending section, heating the pipe locally rather than heating the entire section. This results in faster heating and less deformation during bending. Once the required temperature is reached, the bending device is activated to bend the pipe. Simultaneously, the elastic heating mechanism bends along with the pipe, thus bending the pipe while heating, improving bending efficiency. After bending is complete, the controller disengages the connecting mechanism, and the two sets of heating devices are removed from both ends of the pipe. By setting two sets of heating devices to enter the pipe from both ends, it is easy to remove the two sets of heating devices from the bent pipe after bending is completed; by setting a moving mechanism, it is easy to move inside the pipe, so that the elastic heating mechanism is located at the part of the pipe to be bent, and only the part to be bent is heated locally, the heating speed is faster and the overall deformation is not easily reduced during the bending process; by setting the elastic heating mechanism to bend synchronously with the bending of the pipe, the pipe is bent while being heated, thus improving the bending efficiency.

[0007] Furthermore, the moving mechanism includes a mounting base, an angle adjustment mechanism, a rotating wheel mechanism, and multiple support rods. The mounting base is connected to the elastic heating mechanism, the support rods are connected to the mounting base via the angle adjustment mechanism, the rotating wheel mechanism is mounted on the support rods, and the controller is communicatively connected to both the angle adjustment mechanism and the rotating wheel mechanism. After the heating device is placed inside the pipe, the angle adjustment mechanism is activated to adjust the multiple support rods, causing the rotating wheel mechanism on the support rods to abut against the pipe, facilitating the movement of the heating device within pipes of different inner diameters.

[0008] Furthermore, the angle adjustment mechanism includes a drive motor and a transmission mechanism. The drive motor is mounted on the mounting base, and the support rod is rotatably connected to the mounting base. Both ends of the transmission mechanism are connected to the output end of the drive motor and the support rod, respectively. The controller is communicatively connected to the drive motor. When the position of the support rod needs to be adjusted, the drive motor is activated. The drive motor drives the support rod to rotate on the mounting base via the transmission mechanism, thereby changing the distance between the multiple support rods and causing the rotating wheel mechanism to abut against the inner wall of the pipe.

[0009] Furthermore, the transmission mechanism includes a lead screw, a sliding rod, a sleeve, and a connecting rod. The lead screw is connected to the output end of the drive motor and is located among the multiple support rods. The sliding rod is mounted on the mounting base. The sleeve is threadedly connected to the lead screw and slidably connected to the sliding rod. The two ends of the connecting rod are rotatably connected to the sleeve and the support rod, respectively. When the drive motor is started, the lead screw rotates, and the sleeve moves on the lead screw under the constraint of the sliding rod, thereby driving the support rods to rotate on the mounting base via the connecting rod.

[0010] Furthermore, the rotating mechanism includes a rotating motor, a transmission assembly, and rollers. The rotating motor is mounted on the support rod, and the rollers are rotatably connected to the support rod. Both ends of the transmission assembly are connected to the output end of the rotating motor and the rollers, respectively. The controller is communicatively connected to the rotating motor. Starting the rotating motor drives the rollers to rotate via the transmission assembly, allowing the heating device to move within the pipe.

[0011] Furthermore, the transmission assembly includes a main bevel gear and a driven bevel gear. The main bevel gear is connected to the output end of the rotary motor, the driven bevel gear meshes with the main bevel gear, and the driven bevel gear is connected to the roller. The rotary motor drives the main bevel gear to rotate, and the main bevel gear drives the roller to rotate through the driven bevel gear.

[0012] Furthermore, the moving mechanism also includes a universal joint, through which the elastic heating mechanism is connected to the mounting base. By providing the universal joint, the moving mechanism and the elastic heating mechanism can rotate relative to each other, facilitating the movement of the heating device within a non-straight pipe.

[0013] Furthermore, the connecting mechanism is an electromagnetic element, the elastic heating mechanism is a spring heating coil, and the controller is communicatively connected to both the electromagnetic element and the spring heating coil. After the two sets of heating devices are moved to the desired position, the electromagnetic element is energized, and the electromagnetic element becomes magnetic, causing the two sets of heating devices to connect automatically; when bent, the spring heating coil bends accordingly, and automatically resets after being removed.

[0014] The present invention also provides a pipe bending forming system, comprising an extruder, a forming die, a pipe cutter, a pipe polishing machine, and a pipe bending device arranged in sequence, and further comprising the aforementioned pipe-in-pipe heating robot, wherein the pipe-in-pipe heating robot is located at the pipe bending device.

[0015] The pipe bending forming system of this invention involves adding raw materials to an extruder, melting them, extruding them, and then forming them into pipes through a forming mold. The formed pipes are then cut to a predetermined length by a pipe cutter and moved to a pipe polishing machine for polishing. The pipes are then transported to a pipe bending device, where an internal heating robot is placed inside. This robot heats the area to be bent, and the bending device then bends the pipe. After bending, the internal heating robot is removed. This pipe bending forming system integrates multiple functions, including pipe polishing, pipe heating, and pipe bending, resulting in a high degree of functional integration. Furthermore, during the bending process, the internal heating robot heats the area to be bent in real time, completely eliminating the traditional method of heating the pipe from the outside using a heating device before moving it to the bending machine. In this invention, pipe heating and bending are performed simultaneously, resulting in higher bending efficiency and enabling one-time pipe bending.

[0016] Furthermore, the pipe bending device includes a base plate, a lifting mechanism, a support column, an extrusion component, and a pressure-bearing component. The lifting mechanism and the support column are both mounted on the base plate. The extrusion component is connected to the output end of the lifting mechanism and is slidably connected to the support column. The pressure-bearing component is mounted on the support column opposite to the extrusion component. During pipe bending, the pipe is placed on the extrusion component, and the lifting mechanism is activated to move the extrusion component toward the pressure-bearing component, thus bending the pipe into shape.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention discloses an in-pipe heating robot and a pipe bending forming system, which uses two sets of heating devices to enter the inside of the pipe from both ends for heating, making it easy to remove the two sets of heating devices from the bent pipe after bending is completed; by setting a moving mechanism, it is easy to move inside the pipe, so that the elastic heating mechanism is located at the part of the pipe to be bent, and only the part to be bent is heated locally, the heating speed is faster and the overall deformation is not easily reduced during pipe bending; by setting the elastic heating mechanism to bend synchronously with the bending of the pipe, the pipe is bent while being heated, thereby improving the pipe bending efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The present invention will be further described below with reference to specific embodiments.

In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms describing positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances. Furthermore, if the embodiments of the present invention involve descriptions such as "first" and "second," these descriptions are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In addition, the meaning of "and / or" in the text is that it includes three parallel options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0023] Example 1 This embodiment is the first embodiment of the in-pipe heating robot, such as Figure 1 As shown, it includes two sets of heating devices 100. Each heating device 100 includes a connecting mechanism 200, an elastic heating mechanism 300, and a moving mechanism 400. The two ends of the elastic heating mechanism 300 are connected to the connecting mechanism 200 and the moving mechanism 400, respectively. The controller is communicatively connected to the connecting mechanism 200, the elastic heating mechanism 300, and the moving mechanism 400.

[0024] like Figure 2 As shown, the moving mechanism 400 includes a mounting base 410, an angle adjustment mechanism 420, a rotating wheel mechanism 440, and multiple support rods 430. The mounting base 410 is connected to the elastic heating mechanism 300. The support rods 430 are connected to the mounting base 410 via the angle adjustment mechanism 420. The rotating wheel mechanism 440 is mounted on the support rods 430. The controller is communicatively connected to both the angle adjustment mechanism 420 and the rotating wheel mechanism 440. After the heating device 100 is placed inside the pipe, the angle adjustment mechanism 420 is activated to adjust the multiple support rods 430, causing the rotating wheel mechanism 440 on the support rods 430 to abut against the pipe, facilitating the movement of the heating device 100 within pipes of different inner diameters.

[0025] In this embodiment, there are three support rods 430, and the mounting base 410 is designed as an equilateral triangle structure. The three support rods 430 are located at the three corners of the mounting base 410, and the three support rods 430 have the same length. The rotating wheel mechanism 440 is located at the end of the support rod 430 away from the mounting base 410.

[0026] The moving mechanism 400 also includes a universal joint 450, through which the flexible heating mechanism 300 is connected to the mounting base 410. By providing the universal joint 450, the moving mechanism 400 and the flexible heating mechanism 300 can rotate relative to each other, which facilitates the movement of the heating device 100 in a non-straight pipe.

[0027] The connecting mechanism 200 is an electromagnetic element, and the elastic heating mechanism 300 is a spring heating coil. The controller is communicatively connected to both the electromagnetic element and the spring heating coil. After the two sets of heating devices 100 are moved to the desired positions, the electromagnetic element is energized. The electromagnetic element becomes magnetic, and the two sets of heating devices 100 automatically connect. When bent, the spring heating coil bends accordingly and automatically resets after being removed. The controller controls the energization and de-energization of the electromagnetic element. The spring heating coil is an electric heating element that uses current passing through a resistance wire to generate heat and transfer the heat to the object being heated. This electric heating element is spring-shaped, and the heating temperature is controlled by the controller controlling the current in the spring heating coil.

[0028] It should be noted that the two electromagnetic components have independent circuit control, and the two spring heating coils also have independent circuit control, and the two do not interfere with each other. In addition, the electromagnetic components and the spring heating coils are connected by an insulating component, and the spring heating coils and the universal joint 450 are also connected by an insulating component.

[0029] The working principle of an in-pipe heating robot in this embodiment is as follows: When bending the pipe, place the pipe on the bending equipment. Insert two sets of heating devices 100 into the pipe from both ends. The controller activates the moving mechanism 400, moving the heating devices 100 within the pipe. The two sets of heating devices 100 are connected via the connecting mechanism 200. The position of the elastic heating mechanism 300 is adjusted so that it is positioned at the desired bending point. The two sets of heating devices 100 are positioned on either side of the desired bending section, heating the pipe locally rather than heating the entire section. This results in faster heating and less deformation during bending. Once the required temperature is reached, the bending equipment is activated to bend the pipe. Simultaneously, the elastic heating mechanism 300 bends along with the pipe, thus bending the pipe while heating, improving bending efficiency. After bending, the controller releases the connecting mechanism 200, and the two sets of heating devices 100 are removed from both ends of the pipe. By setting two sets of heating devices 100 to enter the inside of the pipe from both ends for heating, it is easy to remove the two sets of heating devices 100 from the bent pipe after bending is completed; by setting a moving mechanism 400, it is easy to move inside the pipe, so that the elastic heating mechanism 300 is located at the part of the pipe to be bent, and only the part to be bent is heated locally, the heating speed is faster and the overall deformation is not easy during the bending process; by setting the elastic heating mechanism 300 to bend synchronously with the bending of the pipe, the pipe is bent while being heated, thus improving the bending efficiency.

[0030] Example 2 This embodiment is a second embodiment of an in-pipe heating robot. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 3 As shown, the angle adjustment mechanism 420 includes a drive motor 421 and a transmission mechanism 422. The drive motor 421 is mounted on the mounting base 410, and the support rod 430 is rotatably connected to the mounting base 410. Both ends of the transmission mechanism 422 are connected to the output end of the drive motor 421 and the support rod 430, respectively. The controller is communicatively connected to the drive motor 421. When the position of the support rod 430 needs to be adjusted, the drive motor 421 is started. The drive motor 421 drives the support rod 430 to rotate on the mounting base 410 through the transmission mechanism 422, thereby changing the distance between the multiple support rods 430 and causing the rotating wheel mechanism 440 to abut against the inner wall of the pipe.

[0031] like Figure 4As shown, the transmission mechanism 422 includes a lead screw 422a, a sliding rod 422b, a sleeve 422c, and a connecting rod 422d. The lead screw 422a is connected to the output end of the drive motor 421 and is located between multiple support rods 430. The sliding rod 422b is mounted on the mounting base 410, and its axial direction is parallel to that of the lead screw 422a. In this embodiment, there are three sliding rods 422b, which are distributed around the lead screw 422a in an equilateral triangle. To fix the sliding rods 422b, mounting plates are connected to the other end of each sliding rod 422b. The sleeve 422c is threaded to the lead screw 422a and slidably connected to the sliding rod 422b. The two ends of the connecting rod 422d are rotatably connected to the sleeve 422c and the support rods 430, respectively. The drive motor 421 is started, which drives the lead screw 422a to rotate. The sleeve 422c moves on the lead screw 422a under the restriction of the sliding rod 422b, and drives the support rod 430 to rotate on the mounting base 410 through the connecting rod 422d. The two ends of the lead screw 422a are rotatably connected to the mounting base 410 and the mounting plate, respectively, making the movement of the lead screw 422a more stable.

[0032] like Figure 3 As shown, the rotating mechanism 440 includes a rotating motor 441, a transmission assembly 442, and a roller 443. The rotating motor 441 is mounted on a support rod 430, and the roller 443 is rotatably connected to the support rod 430. Both ends of the transmission assembly 442 are connected to the output end of the rotating motor 441 and the roller 443, respectively. The controller is communicatively connected to the rotating motor 441. Starting the rotating motor 441 drives the roller 443 to rotate via the transmission assembly 442, allowing the heating device 100 to move within the pipe. In this embodiment, the roller 443 is a rubber roller.

[0033] The rotating motor 441 is located on the side of the support rod 430, and the rotating shaft of the rotating motor 441 is arranged parallel to the axial direction of the support rod 430. For example... Figure 5 As shown, the transmission assembly 442 includes a main bevel gear 442a and a driven bevel gear 442b. The main bevel gear 442a is connected to the output end of the rotary motor 441, and the driven bevel gear 442b meshes with the main bevel gear 442a. The driven bevel gear 442b is connected to the roller 443. The rotary motor 441 drives the main bevel gear 442a to rotate, and the main bevel gear 442a drives the roller 443 to rotate through the driven bevel gear 442b. The rotation direction is reversed through the main bevel gear 442a and the driven bevel gear 442b.

[0034] Example 3 This embodiment is a first embodiment of a pipe bending forming system, including an extruder, a forming die, a pipe cutter, a pipe polishing machine 500, and a pipe bending device 600 arranged in sequence. That is, the forming die, the pipe cutter, the pipe polishing machine 500, and the pipe bending device 600 are located at the next station of the previous mechanism. It also includes the pipe heating robot provided in Embodiment 1 or Embodiment 2, which is located at the pipe bending device 600.

[0035] like Figure 6 As shown, the pipe bending device 600 includes a base plate 610, a lifting mechanism 620, a support column 630, an extrusion member 640, and a pressure-bearing member 650. The lifting mechanism 620 and the support column 630 are both mounted on the base plate 610. The extrusion member 640 is connected to the output end of the lifting mechanism 620 and is slidably connected to the support column 630. Two support columns 630 are provided, and the two ends of the extrusion member 640 are slidably connected to the two support columns 630 respectively. The pressure-bearing member 650 is mounted opposite the extrusion member 640 on the support column 630, and its two ends are connected to the two support columns 630 respectively. During pipe bending, the pipe is placed on the extrusion member 640, and the lifting mechanism 620 is activated to move the extrusion member 640 toward the pressure-bearing member 650, thus bending the pipe into shape.

[0036] In this embodiment, the pressure-bearing member 650 is located at the top of the support column 630, and the pressure-bearing member 650 is provided with a downwardly arched arc-shaped groove. The lifting mechanism 620 includes a drive cylinder 621, a connecting member 622, a first hinge rod 623 and a second hinge rod 624. The drive cylinder 621 is mounted on the base plate 610, and the connecting member 622 is designed as an isosceles triangle. The output end of the drive cylinder 621 is hinged to the vertex of the connecting member 622. One end of the first hinge rod 623 and the second hinge rod 624 are respectively hinged to the two base corners of the connecting member 622. The other end of the first hinge rod 623 is hinged to the base plate 610, and the other end of the second hinge rod 624 is hinged to the bottom of the pressing member 640. The extrusion component 640 includes a lifting plate 641, a bracket 642, and an extrusion rod 643. The other end of the second hinge rod 624 is hinged to the bottom of the lifting plate 641. The two ends of the lifting plate 641 are slidably connected to two support columns 630 via pulleys. The support columns 630 are provided with guide rails. The two ends of the lifting plate 641 are provided with sliders, which slide in cooperation with the guide rails. The bracket 642 is designed with a V-shaped structure and is located on the lifting plate 641. Each end of the bracket 642 is connected to an extrusion rod 643. The pressure-bearing component 650 is located in the middle of the two extrusion rods 643. During bending, the two ends of the tube are placed on the two extrusion rods 643 respectively, with the part to be bent in the middle. The drive cylinder 621 is activated to drive the connector 622 to move. The connector 622 drives the first hinge rod 623 and the second hinge rod 624 to move, causing the lifting plate 641 to slide on the support column 630. When the pressure member 650 abuts against the upper surface of the tube, that is, the middle part of the tube to be bent is pressed into the arc groove of the pressure member 650, the two ends of the tube are bent under the action of the two extrusion rods 643.

[0037] like Figure 7 As shown, the pipe polishing machine 500 includes a worktable 510, a polishing power unit 520, polishing wheels 530, a fixed base 540, a drive mechanism 550, conveying rollers 560, and supporting rollers 570. Two polishing wheels 530 are provided and are installed on the power output end of the polishing power unit 520, which is mounted on the worktable 510. The two polishing wheels 530 are arranged relatively apart on the worktable 510. Two fixed bases 540 are provided and are located on both sides of the two polishing wheels 530. Two conveying rollers 560 are provided inside the fixed base 540 and are distributed vertically and alternately inside the fixed base 540. Annular grooves are formed on the conveying rollers 560 and the annular grooves on the two conveying rollers 560 are aligned with each other. The drive mechanism 550 is installed on one side of the fixed base 540, and the power output end of the drive mechanism 550 is connected to one of the conveying rollers 560. The drive mechanism 550 is a rotary motor.

[0038] Specifically, the guiding transmission direction of the conveying roller 560 is perpendicular to the distribution direction of the two polishing wheels 530. During the polishing process, the pipe is conveyed to the pipe polishing machine 500 and enters between the two polishing wheels 530 from the two conveying rollers 560 inside the front fixed seat 540. The polishing power unit 520 drives the two polishing wheels 530 to rotate to polish the pipe, thereby removing residual debris and burrs from the pipe surface. The polished pipe is then conveyed out from between the two conveying rollers 560 in the rear fixed seat 540. Two parallel support rollers 570 with a certain distance between them are provided between the fixed seat 540 and the polishing wheels 530. The support rollers 570 support the pipe during the polishing process, and their rolling direction is the same as the rotation direction of the two polishing wheels 530.

[0039] The working principle of the pipe bending forming system in this embodiment is as follows: Raw materials are added to an extruder, melted, and extruded, then formed into pipes through a forming die. The formed pipes are cut to a predetermined length by a pipe cutter and then moved to a pipe polishing machine 500 for polishing. The pipes are then transported to a pipe bending device 600, where an internal heating robot is placed inside. The robot heats the area to be bent, and the bending device 600 then bends the pipe. After bending, the robot is removed. This pipe bending system integrates multiple functions, including pipe polishing, heating, and bending, resulting in a high degree of functional integration. Furthermore, during bending, the internal heating robot heats the area to be bent in real time, completely eliminating the traditional method of heating the pipe from the outside before moving it to the bending machine. In this system, heating and bending occur simultaneously, resulting in higher bending efficiency and enabling one-step bending.
