Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and more specifically, to a pipe bending and cutting device for manufacturing hardware products. Background Technology

[0002] Metal cutting involves a lot of cutting in the processing of hardware products. Hardware products include various metal products, among which pipe bends are one type. Pipe bends are usually used in scenarios such as pipe connection and fluid transportation, and are an important part of hardware products. At the same time, before connecting the pipe bend to the pipeline system, it is usually necessary to use cutting equipment to cut the pipe bend so that it can meet the specific layout requirements of the pipeline connection.

[0003] In practical applications, such as in chemical plants, the connecting pipelines between reactors, storage tanks, and other equipment often require frequent turns, necessitating the use of elbows at specific angles for pipe connections. When cutting these bends, to ensure smooth welding or threaded connection of the cut end to flanges, valves, or fittings, the cut plane is typically required to be perpendicular to the pipe axis. However, because bends have varying bending radii, accurately determining the bending axis is difficult in practice. This makes adjusting the cutting angle challenging when cutting bends with different radii, affecting the perpendicularity of the cut and assembly accuracy, thus limiting the efficiency and quality of bend processing. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a pipe bending and cutting device for manufacturing hardware products.

[0005] The technical solution is as follows:

[0006] A pipe bending and cutting device for manufacturing hardware products includes a base, an adjustment assembly installed on the top of the base, the adjustment assembly including two gears rotatably disposed on the top of the base and symmetrically arranged, the outer walls of the two gears having contact arms that cooperate with the ends of the bent pipe, and a spring-loaded component installed at the top of the base that cooperates with the gears, the spring-loaded component being used to provide a spring force to keep the two contact arms on the gears pressed together in opposite directions.

[0007] A trigger and a housing detachably covering the gears and trigger are slidably mounted on the top of the base along the middle between the two gears. The trigger meshes with the two gears on both sides. A rotating assembly is detachably mounted on the top of the trigger. The rotating assembly is located at the intersection of the extension lines of the inner walls of the two contact arms on the gear. A cutting device for cutting bent pipes is mounted on the rotating end of the rotating assembly.

[0008] The top of the base is fitted with two movable ports that are parallel to each other along the length of the trigger element. A drive assembly is installed at the two movable ports. The drive assembly is used to drive the bent tube to move toward the cutting device until the end of the bent tube is in contact with the contact arm, so as to obtain the bending axis of the bent tube.

[0009] Furthermore, the spring-loaded component includes a connecting arm located on the outer wall of the gear and a mounting seat located on the top of the base. The mounting seat has an arc-shaped guide rod coaxially arranged with the gear. The connecting arm is slidably mounted on the arc-shaped guide rod. An arc-shaped spring is installed between the connecting arm and the mounting seat. The arc-shaped spring is used to provide elastic force to keep the connecting arm rotating inward.

[0010] Furthermore, the driving assembly includes a slider that is slidably disposed within the two movable openings. A hinge seat is installed on the top of each slider, and a roller that mates with the outer wall of the bent pipe is rotatably mounted on the hinge seat. A driving device is installed at the bottom of the base, and the roller is connected to the driving end of the driving device. The driving device is used to drive the slider to move along the movable opening.

[0011] Furthermore, a second guide groove corresponding to the trigger element is provided at the top of the housing. A mounting plate for mounting the rotating component is detachably installed on the top of the trigger element. A protrusion that mates with the second guide groove is installed on the bottom wall of the mounting plate. The outer walls on both sides of the trigger element have toothed sections that mesh with the two gears. A locking component is installed at the top of the housing on the side corresponding to the trigger element. The locking component is used to form a one-way lock on the trigger element.

[0012] Furthermore, a sliding groove is provided at the top of the housing, located on both sides of the second guide groove, and a positioning roller that is slidably disposed in the sliding groove is installed on the bottom wall of the mounting plate.

[0013] Furthermore, the trigger has a slot at the top of the end away from the gear, and the locking assembly includes a mounting post on the housing, a sliding cavity inside the mounting post, a locking member slidably mounted inside the sliding cavity, a pull handle connected to one end of the locking member passing through the top of the mounting post, a locking block that mates with the slot connected to one end of the bottom of the locking member passing through the bottom of the housing, and a spring connected between the top of the locking member and the sliding cavity, the spring being used to maintain the elastic force that provides downward pressing of the locking member.

[0014] Furthermore, the two side walls corresponding to the card block and the card slot have a vertical part and an inclined surface that cooperate with the inner wall of the card slot, respectively. Two positioning holes are opened at the top of the mounting column, and the bottom of the handle has a positioning rod that is inserted into the positioning holes.

[0015] Furthermore, the top of the mounting plate has an angle gauge, and the cutting device includes a rotating seat located on the rotating end of the rotating assembly, with a pointer connected to the outer wall of the rotating seat to cooperate with the angle gauge.

[0016] Furthermore, a first guide groove is provided on the top wall of the active port for the sliding installation of the trigger element.

[0017] Furthermore, a baffle is connected to the top of the inner sidewall of the contact arm.

[0018] As described above, the beneficial effects of the pipe bending and cutting equipment for manufacturing hardware products according to the present invention are as follows:

[0019] By coordinating the drive assembly, adjustment assembly, and trigger, the two ends of the bent tube contact the inner sidewalls of the contact arms on the two symmetrical gears. Combined with the clamping force of the spring mechanism, the two end faces of the bent tube are pushed by the drive assembly to fit against the inner sidewalls of the contact arms. At the same time, the contact arms drive the trigger to move backward, and the backward movement of the trigger drives the rotating assembly and the cutting device on the rotating assembly to move. This allows for precise positioning of the intersection of the extended lines of the two contact arms, which is the bending axis of the bent tube, without the need for manual measurement or repeated adjustments.

[0020] Since the cutting device is installed at the rotating end of the rotating component, the center of rotation is the bending axis. Regardless of the bending radius of the pipe, the cutting device can rotate around this axis, ensuring that the cutting plane is always perpendicular to the pipe axis. This ensures that the cut pipe end can be smoothly welded or threaded to components such as flanges, valves, or joints, thus improving the efficiency and quality of pipe bending.

[0021] The meshing transmission structure of the gear and trigger has an adaptive capability, which can adaptively adjust the contact arm angle according to the curvature of the bend, thus making it compatible with bends of various bending radii.

[0022] By coordinating the locking component and the trigger, when the drive component pushes the two end faces of the bend to fit against the inner sidewall of the contact arm, the gear will drive the trigger to move in the direction of the bend. The locking component can not only limit the movement of the trigger in one direction to prevent the trigger from retracting and affecting the acquisition of the bend's axis, but also work with the drive component to clamp the outer wall, inner wall, and both ends of the bend simultaneously, providing a foundation for stable subsequent cutting.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] The embodiments provided by the present invention will be described in detail below:

[0042] like Figures 1 to 9As shown, a pipe bending and cutting device for manufacturing hardware products includes a base 100. An adjustment assembly 200 is installed on the top of the base 100. The adjustment assembly 200 includes two gears 210 rotatably mounted on the top of the base 100 and symmetrically arranged. The outer walls of the two gears 210 have contact arms 220 that cooperate with the ends of the bent pipe. A spring-loaded component that cooperates with the gears 210 is installed at the top of the base 100. The spring-loaded component is used to provide a spring force to keep the two contact arms 220 on the gears 210 pressed together in opposite directions.

[0043] A trigger 300 and a housing 230 detachably covering the gears 210 and the trigger 300 are slidably mounted on the top of the base 100 at the middle between the two gears 210. The trigger 300 meshes with the two gears 210 on both sides. A rotating assembly 400 is detachably mounted on the top of the trigger 300. The rotating assembly 400 is located at the intersection of the extension lines of the inner walls of the two contact arms 220 on the gear 210. A cutting device 500 for cutting bent pipes is mounted on the rotating end of the rotating assembly 400.

[0044] The rotating component 400 can be a stepper motor or a rotary cylinder. A controller that works with the rotating component 400 is installed on the base 100. The controller is used to control the rotating component 400 to rotate at a specified angle. This is existing technology and will not be described in detail here.

[0045] The top of the base 100 is fitted with two movable ports 110 arranged parallel to the length of the trigger 300. A drive assembly 600 is installed at the two movable ports 110. The drive assembly 600 is used to drive the bent tube to move toward the cutting device 500 until the end of the bent tube is in contact with the contact arm 220, so as to obtain the bending axis of the bent tube.

[0046] It should be noted that, through the coordinated arrangement of the drive assembly 600, the adjustment assembly 200, and the trigger 300, the two ends of the bent tube contact the inner sidewalls of the contact arms 220 on the two symmetrical gears 210. With the clamping force of the spring-loaded component, the two end faces of the bent tube are pushed by the drive assembly 600 to fit against the inner sidewalls of the contact arms 220. At the same time, the contact arms 220 drive the trigger 300 to move backward. The backward movement of the trigger 300 drives the rotating assembly 400 and the cutting device 500 on the rotating assembly 400 to move. This allows for precise positioning of the intersection of the extended lines of the two contact arms 220, which is the bending axis of the bent tube, without the need for manual measurement or repeated adjustments.

[0047] Furthermore, since the cutting device 500 is installed at the rotating end of the rotating assembly 400, the center of rotation is the bending axis. Regardless of the bending radius of the pipe, the cutting device 500 can rotate around this axis, ensuring that the cutting plane is always perpendicular to the pipe axis. This ensures that the cut pipe end can be smoothly welded or threaded to components such as flanges, valves, or joints, thus improving the efficiency and quality of pipe bending.

[0048] It is understandable that the meshing transmission structure of gear 210 and trigger 300 has an adaptive capability, which can adaptively adjust the contact arm angle according to the curvature of the bend, thereby being compatible with bends of various bending radii.

[0049] like Figure 6 As shown, the spring-loaded component includes a connecting arm 211 located on the outer wall of the gear 210 and a mounting base 240 located on the top of the base 100. The mounting base 240 has an arc-shaped guide rod coaxially arranged with the gear 210. The connecting arm 211 is slidably mounted on the arc-shaped guide rod. An arc-shaped spring 250 is installed between the connecting arm 211 and the mounting base 240. The arc-shaped spring 250 is used to provide a spring force to keep the connecting arm 211 rotating inward.

[0050] A baffle 221 is connected to the top of the inner sidewall of the contact arm 220 to limit the top wall of the bend and prevent the bend from rotating upward under the push of the drive assembly 600.

[0051] It should be noted that, since the arc-shaped guide rod and the gear 210 are coaxially arranged, when the gear 210 is squeezed outward by the bent tube, it will drive the connecting arm 211 to move along the arc-shaped guide rod and squeeze the arc-shaped spring 250. The compressed arc-shaped spring 250 provides reverse support to the contact arm 220 until the ends of the bent tube are tightly attached to the inner sidewall of the contact arm 220, thereby obtaining the bending axis of the bent tube. Furthermore, since the two gears 210 are meshed with the trigger 300, the bent tube can automatically fine-tune its alignment during the process of the drive assembly 600 driving the bent tube to move against the inner sidewall of the contact arm 220.

[0052] like Figure 3 As shown, the drive assembly 600 includes sliders 620 slidably disposed within two movable openings 110, wherein the two movable openings 110 are symmetrically arranged along both sides of the cutting device 500. Each slider 620 is equipped with a hinge seat 630 on its top, and a roller 640 that mates with the outer wall of the bent pipe is rotatably mounted on the hinge seat 630. A drive device 610 is installed at the bottom of the base 100, and the roller 640 is connected to the drive end of the drive device 610. The drive device 610 is used to drive the slider 620 to move along the movable openings 110. The drive device 610 can be an electric push rod or a linear module.

[0053] It should be noted that the outer wall of the bend and the roller 640 are in rolling contact, with low friction. This allows the bend to adapt to different diameters and curvatures, always providing a thrust perpendicular to the outer wall of the bend. In conjunction with the two contact arms 220, the bend can automatically center and adjust within a certain range during movement.

[0054] like Figures 3 to 7 As shown, a second guide groove 231 corresponding to the trigger 300 is provided at the top of the housing 230. A mounting plate 310 for mounting the rotating assembly 400 is detachably installed on the top of the trigger 300. A protrusion 311 that cooperates with the second guide groove 231 is installed on the bottom wall of the mounting plate 310. The outer walls on both sides of the trigger 300 have toothed sections 302 that mesh with two gears 210. A locking assembly 700 is installed at the top of the side of the housing 230 corresponding to the trigger 300. The locking assembly 700 is used to form a one-way lock on the trigger 300.

[0055] It should be noted that the mounting plate 310, through the protrusion 311, cooperates with the second guide groove 231 on the housing 230, providing a stable and precisely guided mounting platform for the rotating component 400 and the cutting device 500 supported above, while ensuring that when the two contact arms 220 rotate, the rotating component 400 on the mounting plate 310 is always at the intersection of the extended lines of the inner walls of the two contact arms 220.

[0056] like Figure 8 As shown, a sliding groove 232 located on both sides of the second guide groove 231 is provided at the top of the housing 230, and a positioning roller 320 that is slidably disposed in the sliding groove 232 is installed on the bottom wall of the mounting plate 310.

[0057] It should be noted that the combination of the slide groove 232 and the positioning roller 320 allows the mounting plate 310 to move more smoothly, reducing the friction generated when the mounting plate 310 moves.

[0058] like Figures 3 to 5 As shown, the trigger 300 has a slot 301 at the top of the end away from the gear 210. The locking assembly 700 includes a mounting post 710 on the housing 230. A sliding cavity 711 is opened inside the mounting post 710. A locking member 720 is slidably installed inside the sliding cavity 711. A pull handle 740 is connected to one end of the locking member 720 that passes through the top of the mounting post 710. A locking block 730 that cooperates with the slot 301 is connected to one end of the bottom of the locking member 720 that passes through the bottom of the housing 230. A spring 760 is connected between the top of the locking member 720 and the sliding cavity 711. The spring 760 is used to maintain the elastic force that provides downward pressing of the locking member 720.

[0059] The two side walls of the card block 730 corresponding to the card slot 301 have a vertical part 732 and an inclined surface 731 that cooperate with the inner wall of the card slot 301, respectively. Two positioning holes 712 are opened at the top of the mounting post 710, and the bottom of the handle 740 has a positioning rod 750 that is inserted into the positioning hole 712.

[0060] It should be noted that, through the cooperative arrangement of the locking block 730 and the slot 301, when the trigger 300 moves in the direction of the bend, the inner wall of the slot 301 contacts the inclined surface 731 of the locking block 730, which can push the locking block 730 out of the slot 301 and into the next slot 301, thus completing the movement of the trigger 300. However, due to the vertical part 732 on the locking block 730, the inside of the slot 301 abuts against the vertical part 732, thereby enabling the trigger 300 to move only in the direction of the bend.

[0061] Understandably, by cooperating with the locking component 700 and the trigger 300, when the drive component 600 pushes the two end faces of the bent tube to fit against the inner sidewall of the contact arm 220, the gear 210 will drive the trigger 300 to move in the direction of the bent tube. The locking component 700 can both limit the movement of the trigger 300 in one direction to prevent the trigger 300 from retracting and affecting the acquisition of the bent tube's axis, and cooperate with the drive component 600 to simultaneously clamp the outer wall, inner wall, and both ends of the bent tube, providing a foundation for stable subsequent cutting.

[0062] like Figure 9 As shown, the mounting plate 310 has an angle ruler 312 on its top. The cutting device 500 includes a rotating seat 510 disposed on the rotating end of the rotating assembly 400. A pointer 520 that cooperates with the angle ruler 312 is connected to the outer wall of the rotating seat 510. A cutting machine for cutting bent pipes is mounted on the rotating seat 510, wherein the circular saw blade of the cutting machine is located on the extension line of the rotation center of the rotating assembly 400.

[0063] It should be noted that by using the rotating seat 510 and the angle ruler 312 together, when the rotating cutting device 500 cuts the bent pipe at different angles, the rotating seat 510, that is, the angle of rotation of the cutting device 500, can be observed intuitively. This facilitates the calibration of the angle of rotation of the rotating component 400 and improves the cutting accuracy.

[0064] like Figure 3 As shown, a first guide groove 120 is provided on the top wall of the movable opening 110 for the trigger 300 to be slidably installed. The first guide groove 120 is located in the middle between the two gears 210.

[0065] It should be noted that the first guide groove 120 facilitates the movement of the trigger 300 while providing stable guidance for the trigger 300.

[0066] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, they should all fall within the protection scope of the present invention.
