Description

Technical Field

[0001] This application relates to the field of pipe processing equipment, and more particularly to a bending and cutting device for processing fitness equipment. Background Technology

[0002] Elliptical trainer (e.g.) Figure 1 As a type of fitness equipment, it can simulate natural walking or jogging movements. Equipped with movable handles and foot pedals, the user's arms and legs can move simultaneously, achieving a full-body workout effect. It is widely used in gyms, home fitness environments, or outdoor parks.

[0003] It is known that the handles of elliptical trainers are typically designed with a bent, irregular shape to distinguish them from the main body and to facilitate user grip. In the manufacturing process of fitness equipment, the handles usually require two steps: bending and cutting. In existing technology, the bending and cutting operations of the handles are usually performed separately on bending and cutting equipment. Furthermore, if the tubing used to process the handles is cut first and then bent, the handle may be too small after bending. Therefore, the usual processing order is bending first, then cutting.

[0004] However, after pipes are bent into irregular shapes on bending equipment, fixing them onto cutting equipment for cutting presents certain difficulties. For example, an automatic cutting device for irregularly shaped bent pipes disclosed in Chinese Patent Application Publication No. CN215280436U requires a robotic arm to fix the irregularly shaped pipes; however, the high cost of robotic arms hinders the widespread application of this equipment. Therefore, with the widespread adoption of elliptical machines, how to conveniently and quickly produce irregularly shaped handle parts while reducing equipment costs has become an urgent problem to be solved. Summary of the Invention

[0005] Based on this, this application provides a bending and cutting device for processing fitness equipment, which can complete the bending and cutting of pipes in one go, has the advantage of fast production, and is conducive to reducing equipment costs and promoting its use.

[0006] The bending and cutting device for processing fitness equipment provided in this application adopts the following technical solution:

[0007] A bending and cutting device for processing fitness equipment, comprising:

[0008] The equipment assembly includes a bending mechanism and a cutting mechanism.

[0009] The tooling assembly is slidably disposed on the equipment assembly. The tooling assembly includes a tooling base plate, a fixed base fixed to the tooling base plate, and a sliding base slidably mounted on the tooling base plate. The sliding base cooperates and links with the bending mechanism. In the initial state, the sliding base and the fixed base are spaced apart and form a placement area for placing the pipe. The adjacent sides of the fixed base and the sliding base are respectively provided with a first cavity and a second cavity. The first cavity and the second cavity can be together enclosed to form a forming space for bending the pipe.

[0010] The drive mechanism is located in the equipment assembly and is connected to the tooling assembly to drive the tooling assembly to move. The moving path of the tooling assembly includes a bending moving section and a cutting moving section. When the tooling assembly is in the bending moving section, the bending mechanism forces the sliding base and the fixed base to abut against each other to form a forming space. When the tooling assembly passes through the cutting moving section, the cutting mechanism performs pipe cutting.

[0011] By adopting the above technical solution, this application places the pipe to be processed in the placement area between the fixed base and the sliding base, and controls the drive mechanism to move the tooling assembly towards the cutting mechanism. During the movement of the tooling assembly, it first passes through a bending section. In this section, the sliding base, driven by the bending mechanism, gradually moves towards the fixed base, eventually pressing tightly against the fixed base, thus bending the pipe into the required shape within the forming space. The tooling assembly then continues to move to the cutting section, where the pipe is still held and fixed by the fixed base and the sliding base. After passing through the cutting mechanism, both ends of the pipe are smoothly cut, resulting in a handle portion of the required size. Therefore, this application can complete the bending and cutting of the pipe in one operation, offering the advantage of rapid production, reducing equipment costs, and facilitating widespread use.

[0012] Optionally, the sliding base includes a plurality of sliding inserts arranged in parallel, each sliding insert being slidably mounted on the tooling base plate, and each sliding insert being provided with a first spring between the tooling base plate and the tooling base plate. The first spring is used to force the sliding insert to normally move away from the fixed base; each sliding insert is fixed with a pin at its top.

[0013] The bending mechanism includes a movable plate frame that is slidably mounted on the equipment assembly and a fixed plate frame that is fixedly mounted on the equipment assembly. A positioning pin is provided on the top surface of the tooling base plate. A second spring is provided between the movable plate frame and the equipment assembly. The second spring is used to force the movable plate frame to normally abut against the positioning pin.

[0014] A push plate is slidably mounted on the bottom of the movable plate frame. The push plate and the pins partially overlap in the height direction, and the sliding direction of the push plate is perpendicular to the moving direction of the tooling assembly. A guide post is fixed on the top surface of the push plate, and the fixed plate frame is provided with a guide groove that cooperates with the guide post. The guide post is always located in the guide groove to realize the directional sliding of the push plate on the movable plate frame, so that the push plate abuts against each pin in sequence and forces each sliding insert to move towards the fixed base in sequence.

[0015] By adopting the above technical solution, when the drive mechanism moves to move the tooling assembly, the moving plate frame always abuts against the positioning pin under the elastic force of the second spring, allowing it to move together with the tooling assembly. During the movement of the moving plate frame, the cooperation of the guide post and guide groove enables the push plate to continuously move laterally. As the push plate moves, it gradually abuts against the pins of each sliding insert, pushes the pins, and drives the sliding inserts towards the fixed base. Finally, each sliding insert abuts against the fixed base in sequence to bend and form the pipe. In this method, there is deformation space during pipe bending, and local stress concentration is reduced, which helps to decrease the possibility of local cracking of the pipe during bending and improves the forming quality.

[0016] Optionally, the movable plate frame is provided with a structural groove for the guide column to pass through, the guide column passing through the structural groove and extending above the movable plate frame;

[0017] The guide groove includes an inclined groove section and a straight groove section that are connected. The extension direction of the inclined groove section is set at an angle to the moving direction of the tooling assembly, and the extension direction of the straight groove section is set in the same direction as the moving direction of the tooling assembly. When the guide column moves in the inclined groove section, the tooling assembly is in the bending moving section, and when the guide column moves in the straight groove section, the tooling assembly is in the cutting moving section.

[0018] By adopting the above technical solution, and by setting an inclined groove section, the guide column can force the push plate to gradually move laterally when it moves within the inclined groove section, so that the push plate can push each sliding insert to move towards the fixed base. Finally, the guide column enters the straight groove section and moves within the straight groove section. During the movement, the lateral movement of the guide column is restricted, which allows each sliding insert to remain tightly against the fixed base, making it easier to clamp and position the pipe for subsequent cutting operations.

[0019] Optionally, the positioning pin is located on the side of the first cavity closer to the cutting mechanism, and the outer peripheral surface of the positioning pin is provided with a placement mark for guiding the placement operation. The placement mark is located on the side of the positioning pin away from the cutting mechanism.

[0020] By adopting the above technical solution, the placement mark set on the positioning pin can guide the operator to place the pipe to be processed in the area between the first cavity and the positioning pin, so that when the subsequent sliding base moves towards the fixed base and abuts against the fixed base, the pipe can be bent and shaped smoothly, which is conducive to the normal progress of bending and cutting operations.

[0021] Optionally, the equipment assembly has two fixed track plates, with a moving channel formed between the two track plates at intervals; sliding blocks are fixed on the two opposite sides of the tooling base plate, and the sliding blocks can move smoothly within the moving channel.

[0022] By adopting the above technical solution, the lateral displacement of the tooling plate when it moves in the moving channel can be reduced through the cooperation of the sliding block and the track plate, which is conducive to the smooth movement of the tooling plate.

[0023] Optionally, the drive mechanism includes two slides slidably mounted on the equipment assembly and a drive assembly for driving the two slides to move synchronously. Each slide has a limit slide rod fixed to its top. The limit slide rod is vertically movably fitted with a movable swing arm. The movable swing arm is freely rotatable around the central axis of the limit slide rod, and the free ends of the two movable swing arms abut against each other.

[0024] The tooling base plate is provided with a fixed bracket on the side away from the cutting mechanism. The fixed bracket has a fitting area, and two movable swing arms are matched and locked in the fitting area. The movable swing arms can move upward along the limiting slide bar to disengage from the fitting area.

[0025] By adopting the above technical solution, after the free ends of the two movable swing arms abut against each other, the movable swing arms slide down naturally and are matched and locked in the fitting area. At this time, the control drive component can make the two slides slide smoothly, thereby moving the movable swing arms with the tooling assembly towards the cutting mechanism to smoothly complete the bending and cutting operations. In addition, by moving the movable arm plate upward along the limit slide bar to the limit position, the movable swing arms can be easily replaced after disengaging from the fitting area. By replacing the tooling assemblies with different shapes or sizes of forming spaces, the production of different types of handle parts can be quickly switched, thereby improving the compatibility and adaptability of the equipment and making it more conducive to widespread use.

[0026] Optionally, the cutting mechanism includes two sets of cutting components located on opposite sides of the tooling assembly's movement path. The equipment assembly has a dust collection trough and two material drop troughs. The dust collection trough is located between the two sets of cutting components, and the two material drop troughs are located on opposite sides of the two sets of cutting components. A collection box is installed at the bottom of the equipment assembly in a pull-out manner, and the collection box is located directly below the dust collection trough and the two material drop troughs.

[0027] By adopting the above technical solution and setting two material drop troughs, the waste material formed after the pipe ends are cut can fall into the collection box through the material drop troughs, while the metal shavings generated during the cutting process can fall into the collection box through the material drop troughs or dust collection troughs. This has the advantage of being easy to clean and is conducive to the collection and recycling of waste material shavings.

[0028] Optionally, the cutting assembly includes a rotary motor fixed to the equipment assembly and a cutting blade coaxially connected to the output end of the rotary motor, and the equipment assembly is fixed with a protective cover covering the cutting blade.

[0029] By adopting the above technical solution, the cutting blade can be rotated at high speed by controlling the operation of the rotating motor. The pipe to be processed can be cut smoothly when it passes through the cutting blade, thereby obtaining the handle part of the required length. The protective cover can protect the operator and reduce the possibility of the operator being accidentally cut by the cutting blade.

[0030] Optionally, the equipment assembly is provided with an air shower mechanism for blowing away metal debris. The air shower mechanism includes an outer cover plate fixed to the equipment assembly, a fan assembly fixed to one side of the outer cover plate, and a negative pressure assembly fixed to the other side of the outer cover plate. An air shower area is formed between the fan assembly and the negative pressure assembly, and the air shower area spans the bending movement section and the cutting movement section.

[0031] By adopting the above technical solution, when the pipe is bent and formed and enters the cutting section for cutting operations, the positive pressure air generated by the operation of the fan assembly can enter the air shower area and blow up the metal debris attached to the surface of the tooling assembly or the surface of the pipe. The metal debris can be smoothly drawn away under the negative pressure of the negative pressure assembly, thereby reducing the occurrence of flying metal debris and helping to maintain the good health of the workers.

[0032] Optionally, the air shower mechanism also includes a switch assembly for controlling the start and stop of the fan assembly. The switch assembly includes a mounting base fixed to the equipment assembly and a rotating handle rotatably fitted into the mounting base. A torsion spring is provided between the rotating handle and the mounting base. A limit stop bar is fixedly connected to the mounting base, and the torsion spring is used to force the rotating handle to normally abut against the limit stop bar.

[0033] One end of the rotating handle is equipped with a telescopic component. In the initial state, the telescopic component is located on the moving path of the slide. When the drive mechanism is activated, the slide can abut against the telescopic component and force the telescopic component to retract inward. The other end of the rotating handle is equipped with an extension rod. The mounting base is embedded with a contact sensor. The contact sensor is electrically connected to the control module to control the start and stop of the fan assembly. When the drive mechanism is reset, the slide can abut against the telescopic component and drive the rotating handle to rotate, thereby causing the extension rod to abut against the contact sensor.

[0034] By adopting the above technical solution, this application sets up a switch assembly to control the start and stop of the fan assembly. When the drive mechanism moves and the tooling assembly moves towards the cutting mechanism, the sliding sleeve can abut against the telescopic component and force the telescopic component to retract inward. At this time, the contact sensor is always in the initial state and the fan assembly is in the stopped state. This can reduce the direct action of high wind pressure on the pipe when the pipe to be processed is not clamped and positioned, thereby reducing the occurrence of pipe displacement and the resulting length not meeting the requirements after cutting.

[0035] During the process of the drive mechanism resetting and the tooling assembly moving away from the cutting mechanism, the slide can abut against the telescopic component and drive the rotating handle to rotate. Finally, the extension rod at the end of the rotating handle can abut against the contact sensor, causing the state of the contact sensor to change. At this time, the contact sensor can send a signal to the control module to control the fan assembly to start running, thereby successfully blowing away the metal debris attached to the surface of the tooling assembly or the surface of the pipe.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. This application completes the bending operation of the pipe by cooperating with the fixed base and the sliding base, and completes the cutting operation of the pipe by the cutting mechanism; in the specific operation process, the bending and cutting operations of the pipe can be completed in one action by controlling the action of the drive mechanism, which has the advantages of fast production, while also helping to reduce equipment costs and promote its use.

[0038] 2. During the movement of the tooling assembly, each sliding insert is sequentially pressed against the fixed base. When bending the pipe, there will be a deformation allowance, and there will be less local stress concentration. This helps to reduce the possibility of local cracking of the pipe during bending and improve the forming quality.

[0039] 3. By setting a switch assembly to control the start and stop of the fan assembly, the fan assembly is in a stopped state as the tooling assembly moves closer to the cutting mechanism. This can reduce the direct impact of high air pressure on the pipe when the pipe to be processed is not clamped and positioned, thereby reducing the occurrence of pipe displacement and the resulting length not meeting requirements after cutting.

[0059] The following is in conjunction with the appendix Figure 2 -Appendix Figure 13 This application will be described in further detail.

[0060] This application discloses a bending and cutting device for processing fitness equipment, mainly used for processing tubular parts with irregular shapes on elliptical machine handles or other equipment.

[0061] Reference Figure 2 A bending and cutting device for processing fitness equipment includes an equipment assembly 1 and a tooling assembly 2, wherein the tooling assembly 2 is replaceably installed on the equipment assembly 1. In the specific production process, by replacing different types of tooling assemblies 2, it can be used to produce handle parts of different shapes or sizes, thereby improving the usability and compatibility of the equipment.

[0062] Reference Figure 3 The tooling assembly 2 includes a tooling base plate 21, a fixed base 22, and a sliding base 23. Multiple recessed slots are respectively formed on two opposite sides of the tooling base plate 21. A sliding block 24 is fitted into each recessed slot, and the sliding block 24 partially protrudes from the side of the tooling base plate 21. (See also...) Figure 4 Two track plates 11 are fixed on the top surface of the equipment assembly 1. The cross-sectional shape of the track plates 11 is an inverted L shape, and the two track plates 11 are spaced apart to form a moving channel 12. When the tooling base plate 21 enters the moving channel 12, the sliding block 24 can match and abut against the inner side of the track plate 11 to restrict the lateral movement of the tooling base plate 21, so that it can only move along the extension direction of the moving channel 12.

[0063] It should be noted that when the tooling assembly 2 is installed on the equipment assembly 1, the tooling base plate 21 will be located at one end of the extension direction of the track plate 11 in the initial state; the distance between the two track plates 11 gradually decreases from the end closer to the tooling base plate 21 to the other end. Based on this, the tooling base plate 21 can be guided into the moving channel 12 when it moves, so as to facilitate the normal operation of subsequent bending and cutting operations.

[0064] Back Figure 3 The fixed base 22 is fixed to the top surface of the tooling base plate 21; the sliding base 23 includes a plurality of sliding inserts 231, each sliding insert 231 is slidably installed on the tooling base plate 21 through the cooperation of the slider groove, and the sliding inserts 231 are arranged side by side, with adjacent sliding inserts 231 abutting against each other; when the tooling assembly 2 is installed on the equipment assembly 1, each sliding insert 231 is located on the side of the fixed base 22 close to the track plate 11, and the sliding direction of the sliding insert 231 is the same as the extension direction of the track plate 11.

[0065] Simultaneously refer to Figure 5 In this embodiment, a guide seat 211 is fixed at the bottom of the tooling substrate 21, and a plurality of guide posts 233 are fixed on the guide seat 211. The axial direction of the guide posts 233 is the same as the moving direction of the sliding insert 231, and the number of guide posts 233 is equal to the number of sliding inserts 231. The bottom slider of the sliding insert 231 extends to the bottom of the tooling substrate 21, and each guide post 233 is movably inserted through the bottom slider of the corresponding sliding insert 231.

[0066] Each guide post 233 is fitted with a first spring 232 on its outer periphery. One end of the first spring 232 abuts against the bottom slider of the sliding insert 231, and the other end abuts against the guide seat 211. The first spring 232 can always generate an elastic force acting on the sliding insert 231, thereby forcing the sliding insert 231 to move away from the fixed base 22 in a normal direction. At this time, each sliding insert 231 and the fixed base 22 can be spaced apart from each other, thereby forming a placement area 25 for placing the pipe.

[0067] Back Figure 3The fixed base 22 has a first cavity 221 on the side near the sliding insert 231. Each sliding insert 231 has an inner groove on the side near the fixed base 22. The sliding inserts 231 are arranged side by side in the initial state, so that the inner grooves are combined to form a second cavity 234. In this embodiment, the cross-sectional shape of the first cavity 221 and the cross-sectional shape of the second cavity 234 are both semi-circular. When the sliding base 23 moves towards the fixed base 22 and finally abuts against the fixed base 22, the first cavity 221 and the second cavity 234 can be enclosed to form a forming space. The shape of the forming space can be designed to be the same as the shape of the pipe to be bent, so as to facilitate the bending and forming operation of the pipe.

[0068] Reference Figure 4 The equipment assembly 1 is provided with a drive mechanism 3 for moving the tooling assembly 2. Specifically, two sliding grooves 13 are provided through the top surface of the equipment assembly 1. The two sliding grooves 13 are located on opposite sides of the two track plates 11, and the extension direction of each sliding groove 13 is the same as the extension direction of the track plate 11. The drive mechanism 3 includes two slides 31 and a drive assembly for moving the slides 31. The two slides 31 are slidably mounted on the two sliding grooves 13. (Refer to...) Figure 6 Furthermore, a cross link 32 is connected and fixed between the two slides 31, enabling the two slides 31 to move synchronously.

[0069] Reference Figure 6 In this embodiment, the driving component is a long-stroke linear cylinder 33, with two sets of linear cylinders 33 respectively disposed at both ends of the horizontal connecting rod 32. The cylinder body of the linear cylinder 33 is fixed to the inner top wall of the equipment assembly 1, and the movable end of the linear cylinder 33 is sleeved on the horizontal connecting rod 32. Based on this, by controlling the movement of the linear cylinder 33 to pull the horizontal connecting rod 32, the slide table 31 can be driven to move along the sliding groove 13.

[0070] Reference Figure 7 Each slide 31 has its top surface extending to the top of the equipment assembly 1. A limiting slide rod 34 is vertically fixed to the top of the slide 31. A movable swing arm 35 is vertically fitted onto the limiting slide rod 34, allowing the movable swing arm 35 to move along the axis of the limiting slide rod 34 and rotate circumferentially around the central axis of the limiting slide rod 34. In addition, the end of the limiting slide rod 34 is provided with a limiting end cap 341 to prevent the movable swing arm 35 from disengaging. Each movable swing arm 35 has a tenon joint 351 at the end away from the limiting slide rod 34. When two movable swing arms 35 rotate to face each other, the two tenon joints 351 allow the movable swing arms 35 to abut against each other.

[0071] Simultaneously refer to Figure 3A fixing bracket 26 is fixed to the side of the tooling base plate 21. When the tooling assembly 2 is installed on the equipment assembly 1, the fixing bracket 26 can be located on the side of the tooling base plate 21 away from the track plate 11. The top of the fixing bracket 26 has a fitting area 261. When the two movable swing arms 35 abut against each other and slide naturally along the limiting slide bar 34 under the action of gravity, the two movable swing arms 35 can match and enter the fitting area 261. At this time, by controlling the linear cylinder 33 to move, the movable swing arms 35 can be used to pull the tooling assembly 2 to move, so that the tooling assembly 2 can smoothly enter the moving channel 12. In addition, when it is necessary to replace the handle part of another model or size, by moving the movable swing arm 35 upward to abut against the limiting end cover 341, the movable swing arm 35 can disengage from the fitting area 261, so that the operator can easily take out the tooling assembly 2 and put on the new required tooling assembly 2, which has the advantage of convenient replacement.

[0072] Reference Figure 2 , Figure 4 The equipment assembly 1 is also provided with a bending mechanism 4 for driving the pipe to bend and forming, and a cutting mechanism 5 for cutting both ends of the pipe. The cutting mechanism 5 is located at the rear end of the bending mechanism 4 along the moving direction of the tooling assembly 2. Based on this, the overall moving path of the tooling assembly 2 can be divided into a bending moving section and a cutting moving section. When the tooling assembly 2 is in the bending moving section, the sliding base 23 gradually abuts against the fixed base 22 under the drive of the bending mechanism 4 to achieve bending of the pipe. When the tooling assembly 2 is in the cutting moving section, the tooling assembly 2 can move to the cutting mechanism 5 to cut the pipe.

[0073] Reference Figure 8 Specifically, the bending mechanism 4 includes a movable plate frame 41, a fixed plate frame 42, and two sets of support structures 43. The two sets of support structures 43 are respectively set on opposite sides of the two sliding grooves 13. Each set of support structures 43 includes two plate frame seats 431. Each plate frame seat 431 is fixed to the top of the equipment assembly 1, and a first support rod 432 and a second support rod 433 are fixedly connected between the two plate frame seats 431. The movable plate frame 41 is slidably set on the first support rod 432, while the fixed plate frame 42 is fixedly set on the second support rod 433. The movable plate frame 41 is always located above the tooling assembly 2, while the fixed plate frame 42 can be located above the movable plate frame 41.

[0074] Simultaneously refer to Figure 3The top surface of the tooling base plate 21 is vertically fixed with a positioning pin 27. There are two positioning pins 27, which are respectively located on the two sides of the tooling base plate 21 in the width direction. The positioning pins 27 and the movable plate frame 41 partially overlap in the height direction. A second spring 411 is provided between the movable plate frame 41 and the plate frame seat 431. The second spring 411 is sleeved on the first frame rod 432. The second spring 411 can always generate an elastic force acting on the movable plate frame 41, thereby forcing the movable plate frame 41 to keep against the positioning pin 27. When the tooling assembly 2 moves, it can smoothly move the movable plate frame 41 together through the abutment cooperation between the positioning pin 27 and the movable plate frame 41.

[0075] In addition, refer to Figure 3 In this embodiment, the positioning pin 27 can be located on the side of the first cavity 221 close to the track plate 11. The outer peripheral surface of the positioning pin 27 is provided with an arrow-shaped placement mark 271, which can be used to guide the operator's placement operation, that is, to guide the operator to place the pipe to be processed in which position of the tooling assembly 2. The placement mark 271 is located on the side of the positioning pin 27 away from the track plate 11.

[0076] Reference Figure 9 , Figure 10 The bottom of the movable plate frame 41 is slidably mounted with a push plate 412 via a slide rail slider. The sliding direction of the push plate 412 is perpendicular to the extension direction of the track plate 11. A guide column 413 is fixedly connected to the top of the push plate 412. The movable plate frame 41 has a structural groove. The extension direction of the structural groove is the same as the movement direction of the movable plate frame 41. The guide column 413 can pass through the structural groove and extend to the top of the movable plate frame 41.

[0077] The fixed plate frame 42 has a vertically penetrating guide groove 421, and the guide post 413 is always located within the guide groove 421. Specifically, the guide groove 421 includes a connected inclined groove section 422 and a straight groove section 423. The extension direction of the inclined groove section 422 is set at an angle to the extension direction of the track plate 11, while the extension direction of the straight groove section 423 is set in the same direction as the extension direction of the track plate 11. When the tooling assembly 2 is in the bending movement section, the guide post 413 will move within the inclined groove section 422; and when the tooling assembly 2 is in the cutting movement section, the guide post 413 will move within the straight groove section 423.

[0078] Back Figure 3 Each sliding insert 231 has a pin 235 fixed to its top. The pin 235 partially overlaps with the push plate 412 in the height direction. In the initial state, the push plate 412 and each pin 235 are spaced apart. The push plate 412 can be positioned directly opposite each pin 235 along its own moving direction. (Note: The last part, "reference," appears to be a separate, unrelated statement and is left untranslated.) Figure 9 , Figure 10The push plate 412 has an inclined guide surface 414 on its side near the pin 235. When the drive mechanism 3 moves to drive the tooling assembly 2 to move in the bending section, the cooperation between the guide post 413 and the inclined groove section 422 can force the push plate 412 to gradually slide towards each pin 235. Finally, the inclined guide surface 414 of the push plate 412 can abut against each pin 235 in sequence, thereby forcing each sliding insert 231 to move towards the fixed base 22 in sequence. Finally, each sliding insert 231 can abut against the fixed base 22 in sequence to complete the bending operation of the pipe.

[0079] After the guide post 413 passes through the inclined groove section 422 and enters the straight groove section 423, the lateral movement of the guide post 413 is restricted, and each sliding insert 231 can remain tightly against the fixed base 22 to securely clamp the pipe, which facilitates the subsequent cutting of both ends of the pipe to obtain the required length.

[0080] Back Figure 4 , Figure 6 The cutting mechanism 5 includes two sets of cutting components, which are respectively located on opposite sides of two track plates 11. Each cutting component includes a rotating motor 51 fixed to the top wall of the equipment assembly 1 and a cutting blade 52 coaxially connected to the output end of the rotating motor 51. The equipment assembly 1 has a clearance groove, through which the cutting blade 52 passes and is partially exposed on the top surface of the equipment assembly 1. In addition, the equipment assembly 1 is also fixed with a protective cover 53, which covers the cutting blade 52 to protect the operator.

[0081] Reference Figure 6 The top surface of the equipment assembly 1 is provided with a dust collection trough 14 and two material drop troughs 15. The dust collection trough 14 is located between the two sets of cutting components, while the two material drop troughs 15 are located on opposite sides of the two sets of cutting components; at the same time, refer to Figure 11 The bottom of the equipment assembly 1 is provided with a collection box 16. The collection box 16 is installed in the equipment assembly 1 by a pull-out method, and the collection box 16 is directly below the dust collection tank 14 and the two material drop tanks 15. It can collect and recycle the waste and metal shavings generated after pipe cutting, and has the advantage of being easy to clean.

[0082] Reference Figure 8The equipment assembly 1 is also equipped with an air shower mechanism 6 for blowing away metal debris. Specifically, the air shower mechanism 6 includes an outer cover plate 61, a fan assembly 62, a negative pressure assembly 63, and a switch assembly 64. The outer cover plate 61 is fixed to the top of the equipment assembly 1. In this embodiment, the outer cover plate 61 is U-shaped and can partially cover the bending mechanism 4 and the cutting mechanism 5. The fan assembly 62 is fixedly installed on one side of the outer cover plate 61 to provide a strong positive pressure airflow, while the negative pressure assembly 63 is fixedly installed on the other side of the outer cover plate 61 to provide negative pressure suction. An air shower area is formed between the fan assembly 62 and the negative pressure assembly 63, and the air shower area spans the bending moving section and the cutting moving section.

[0083] Specifically, the negative pressure assembly 63 includes a negative pressure cover 631 fixed to the side of the outer cover plate 61, a negative pressure fan installed inside the negative pressure cover 631, and a bellows 632 connected to the negative pressure cover 631. The end of the bellows 632 away from the negative pressure cover 631 is connected to the collection box 16, which can blow the collected metal debris into the collection box 16 for easy cleaning. It should be noted that in this embodiment, the collection box 16 is divided into two areas by a partition. In the initial state, the area connected to the bellows 632 can remain closed so that metal debris can be collected in this area.

[0084] Reference Figure 12 The switch assembly 64 is configured to control the start and stop of the fan assembly 62 in real time. Specifically, the switch assembly 64 includes a mounting base 641 and a rotating handle 642. The mounting base 641 is fixed to the top of the equipment assembly 1 and located outside the sliding groove 13. The rotating handle 642 is rotatably fitted into the middle of the mounting base 641 via a rotating shaft, and the rotating shaft is located in the middle section of the rotating handle 642. A telescopic component 644 is installed at one end of the rotating handle 642. In the initial state, the telescopic component 644 is partially located on the moving path of the slide table 31. An integrally formed extension rod 645 is provided at the other end of the rotating handle 642 away from the telescopic component 644.

[0085] In addition, refer to Figure 13 The mounting base 641 is vertically connected to a limit stop 646. The limit stop 646 is located at the rear end of the rotating handle 642 along the moving direction of the tooling assembly 2. A torsion spring 643 is provided at the rotation connection between the rotating handle 642 and the mounting base 641. The torsion spring 643 can always generate a torque acting on the rotating handle 642, thereby forcing the rotating handle 642 to normally abut against the limit stop 646.

[0086] It can be seen that when the drive mechanism 3 moves and drives the tooling assembly 2 to move closer to the cutting mechanism 5, the slide table 31 can abut against the telescopic component 644. At this time, since the limit stop 646 restricts the rotation of the rotating handle 642, the slide table 31 can retract the telescopic component 644 inward so that the slide table 31 can pass smoothly through the telescopic component 644.

[0087] Mounting base 641 is fitted with a contact sensor 647, which is positioned opposite the extension rod 645 and is electrically connected to the control module. The control module can be used to control the start and stop of the fan assembly 62. When the drive mechanism 3 drives the pipe to complete the cutting operation and retract, the slide table 31 can also abut against the telescopic component 644 during its retraction. At this time, the slide table 31, along with the telescopic component 644 and the rotating handle 642, rotates around the central axis of the rotating shaft, while the extension rod 645 rotates towards the contact sensor 647. Finally, the extension rod 645 abuts against the contact sensor 647, at which point the state signal of the contact sensor 647 changes, sending a signal to the control module to control the operation of the fan assembly 62 to blow away metal debris adhering to the surface of the tooling assembly 2 or the pipe surface.

[0088] After the slide table 31 moves away from the telescopic component 644, the rotating handle 642 resets under the torque of the torsion spring 643. At this time, the extension rod 645 disengages from the contact sensor 647, causing the status signal of the contact sensor 647 to return to its initial state, thus enabling the fan assembly 62 to remain stationary. Based on this, this design reduces the direct impact of high wind pressure on the pipe when it is not clamped and positioned, thereby reducing the likelihood of pipe misalignment and subsequent non-compliance with cut length requirements, and helping to ensure the forming quality of the pipe after bending and cutting.

[0089] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
