Description

Technical Field

[0001] This invention belongs to the field of bending equipment technology, specifically a multi-station synchronous bending and forming equipment and method for automotive seat frame tubular components. Background Technology

[0002] Automotive seat frame tubing is a specialized metal tubing that forms the frame of seat cushions and backrests. It is typically made of high-strength welded steel pipes, formed through bending, cutting, and welding, and concealed within the seat foam and fabric. As the core load-bearing component of the seat, it bears the occupant load and provides an installation reference for adjusters, slide rails, and seat belts. It must meet requirements for stiffness, fatigue, and collision safety, ensuring structural strength while maintaining lightweight design. It is widely used in various passenger vehicle seat frame assemblies. Bending equipment is required when bending automotive seat frame tubing.

[0003] While existing bending equipment can process structures, it typically only has a single processing station, allowing for the bending of only one tube at a time, resulting in extremely low processing efficiency. Furthermore, it cannot quickly position the tubes during installation, and the adjustment range of the installation structure is limited. When installing irregularly shaped tubes, it cannot be effectively adjusted, thus restricting the processing range of the equipment and leading to poor practical application results. To solve these problems, there is an urgent need for multi-station synchronous bending and forming equipment and methods for automotive seat frame tubes. Summary of the Invention

[0011] The motor is installed inside the base. One end of the output shaft of the motor is fixedly installed with a bidirectional screw. The external thread of the bidirectional screw is fitted with a second electric lifting frame. The top of the second electric lifting frame is fixedly installed with a mounting rail.

[0012] As a further preferred embodiment of this technical solution: side grooves are provided on both sides of the mounting rail, the second electric lifting frame is slidably installed inside the horizontal groove, and the second electric lifting frame is slidably connected to the guide rail fixedly installed inside the horizontal groove through the sliding groove provided at its bottom.

[0013] As a further preferred embodiment of this technical solution, the mounting mechanism further includes:

[0014] The installation accessories include a movable block, which is slidably installed on the outside of the installation rail via a groove provided at its bottom. A pipe fitting clamp is rotatably installed on the top of the movable block via a rotating shaft. Side shells are provided on both outer walls of the pipe fitting clamp. An inner groove is provided inside the side shell. A square groove is provided inside the pipe fitting clamp. A stroke groove is provided on the top surface of the side shell.

[0015] As a further preferred embodiment of this technical solution, the mounting mechanism further includes:

[0016] A positioning component is disposed inside the inner groove. The positioning component includes a positioning plate and a pressing block. The positioning plate is slidably installed inside the inner groove by a built-in spring.

[0019] This invention also discloses a method for using a multi-station synchronous bending and forming equipment for automotive seat frame tubing, comprising the following steps:

[0020] S1. When installing the skeleton pipe fittings, first install the pipe fittings. Based on the overall length of the pipe fittings, adjust the distance between the two sets of installation mechanisms, and directly start the installation motor to control the bidirectional screw to rotate, thereby controlling the synchronous displacement of the two sets of installation mechanisms to meet the installation requirements of the pipe fittings.

[0021] S2. According to the irregular shape of the pipe fitting, adjust the installation accessories to move outside the installation rail and rotate the overall positioning component to meet the installation requirements of the two ends of the pipe fitting. At this time, insert the two ends of the pipe fitting into the grooves of the two pipe fitting clamping blocks respectively. At this time, the pressing block moves downward under pressure, and simultaneously drives the insertion shafts and side plates on both sides to move downward. At this time, one end of the insertion shaft can be disengaged from the bottom hole on the bottom surface of the positioning plate. At this time, the built-in spring is no longer restricted, and the positioning plate can be pushed out, pressing the two ends of the pipe fitting into the grooves of the pipe fitting clamping blocks respectively, thus completing the installation of the two ends of the pipe fitting.

[0022] S3. When the positioning plate is pushed out, pressing the two ends of the pipe fitting into the grooves of the pipe fitting clamp, the extrusion plate can also deflect downward under the action of the torsion spring, so that one end of the extrusion plate extrudes the upper surface of the pipe fitting, further improving the installation effect of the two ends of the pipe fitting, avoiding residual gaps between the positioning plate and the pipe fitting, and further ensuring the stability of the pipe fitting when bending.

[0023] S4. When bending pipe fittings, multiple pipe fittings can be installed on different bending mechanisms simultaneously. By controlling the motor to turn on, the drive bevel gear can be rotated. The drive bevel gear can drive multiple driven bevel gears on the outside to rotate synchronously, thereby driving the threaded column to rotate synchronously, thereby driving multiple sets of bending mechanisms to move synchronously, so that multiple bending wheels can simultaneously achieve the bending of multiple sets of pipe fittings.

[0024] S5. During bending, the height of the first electric lifting frame can be adjusted in real time according to the installation height of the pipe fitting, so that the bending wheel is located at the center bending height of the pipe fitting, so that the bending wheel can stably complete the bending of the pipe fitting. In addition, depending on the curvature requirements at the bending point, the bending wheel can be rotated to adjust the extrusion wheel of different diameters for bending processing.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. In this invention, by setting up two sets of easily adjustable installation mechanisms, the above design enables the quick installation of both ends of the pipe fitting during bending, without the need for external positioning structures and parts. The operation is simple and time-saving. Furthermore, the two sets of installation mechanisms have multi-dimensional adjustment functions for height and horizontal adjustment. During installation, the distance between the two sets of installation mechanisms can be adjusted according to the overall length of the pipe fitting, and the position and angle of the positioning components can be adjusted according to the shape of the pipe fitting to make it fit the shape of the pipe fitting, which greatly improves the applicability of the equipment.

[0027] 2. In this invention, a pressing plate is also provided in the positioning component. When the positioning plate is pushed out, it presses the two ends of the pipe fitting into the groove of the pipe fitting block. The pressing plate can also be deflected downward under the action of the torsion spring, so that one end of the pressing plate presses the upper surface of the pipe fitting. This further improves the installation effect of the two ends of the pipe fitting, avoids the residual gap between the positioning plate and the pipe fitting, further ensures the stability of the pipe fitting when bending, prevents the pipe fitting from popping out when bending, and ensures work safety.

[0028] 3. In this invention, by setting up multiple sets of bending mechanisms and installing drive conical gears inside the equipment, the synchronous bending of multiple sets of pipe fittings can be completed simultaneously, greatly improving the overall working efficiency of the equipment. At the same time, the height of the bending wheels can be adjusted synchronously according to the installation position of the pipe fittings to adapt to the bending requirements. Furthermore, the extrusion wheels of different diameters can be quickly adjusted according to the curvature requirements of the pipe fitting bending point, further improving the precision of the equipment's bending and enhancing the actual application effect of the equipment.

Side grooves 43 are provided on both sides of the mounting rail 42. The second electric lifting frame 44 is slidably installed inside the transverse groove 6. The second electric lifting frame 44 is slidably connected to the guide rail 7 fixedly installed inside the transverse groove 6 through the sliding groove provided at its bottom.

[0044] The installation mechanism 4 also includes:

[0045] The mounting accessory 41 includes a movable block 414, which is slidably mounted on the outside of the mounting rail 42 via a groove provided at its bottom. A pipe fitting clamping block 417 is rotatably mounted on the top of the movable block 414 via a rotating shaft. Side shells 413 are provided on both outer walls of the pipe fitting clamping block 417. An inner groove 415 is provided inside the side shell 413. A square groove 416 is provided inside the pipe fitting clamping block 417. A travel groove 412 is provided on the top surface of the side shell 413.

[0046] The installation mechanism 4 also includes:

[0047] A positioning component 411 is disposed inside the inner groove 415. The positioning component 411 includes a positioning plate 4111 and a pressing block 4119. The positioning plate 4111 is slidably mounted inside the inner groove 415 by a built-in spring 4113. An operating block is provided on the top surface of the positioning plate 4111. One end of the operating block passes through and extends to the outside of the travel groove 412. The pressing block 4119 is movably mounted inside the square groove 416 by a pressure spring 41110. One end of the pressing block 4119 passes through and extends to the outside of the square groove 416. Side plates 4118 are fixedly installed on both outer walls of the pressing block 4119.

One end of the plug shaft 4117 is inserted into the bottom hole 4112 provided on the bottom surface of the positioning plate 4111.

[0048] Furthermore, during the installation of the skeleton pipe fittings, the pipe fittings are installed first. Based on the overall length of the pipe fittings, the distance between the two sets of installation mechanisms 4 is adjusted. The installation motor 45 is directly turned on to control the rotation of the bidirectional screw 46, thereby controlling the synchronous displacement of the two sets of installation mechanisms 4 to meet the installation requirements of the pipe fittings. At the same time, based on the irregular shape of the pipe fittings, the installation accessories 41 are adjusted to move outside the installation rail 42, and the overall positioning component 411 can be rotated to meet the installation requirements of the two ends of the pipe fittings. At this time, the two ends of the pipe fittings are respectively inserted into the grooves of the two pipe fitting clamping blocks 417. At this time, the pressing block 4119 is pressed downward, which synchronously drives the insertion shafts 4117 and the side plates 4118 on both sides to move downward. At this time, one end of the insertion shaft 4117 can be disengaged from the bottom hole 4112 on the bottom surface of the positioning plate 4111. At this time, the built-in spring 4113 is no longer restricted, and the positioning plate 4111 can be pushed out, pressing the two ends of the pipe fittings into the grooves of the pipe fitting clamping blocks 417, thus completing the installation of the two ends of the pipe fittings.

[0049] The above technical solution enables quick installation of both ends of the pipe fitting during bending, eliminating the need for external positioning structures and parts. This simple and time-saving operation, along with the multi-dimensional adjustment functions of the two installation mechanisms 4 (height and level), allows for adjustment of the distance between the two installation mechanisms 4 according to the overall length of the pipe fitting, and adjustment of the position and angle of the positioning component 411 according to the shape of the pipe fitting, thus greatly improving the applicability of the equipment.

[0050] Please see Figure 7 The bottom of the positioning plate 4111 is provided with a storage groove 4114. Inside the storage groove 4114, a pressing plate 4116 is rotatably installed via a rotating shaft. A torsion spring 4115 is fixedly installed outside the rotating shaft. One end of the torsion spring 4115 is fixedly connected to the inner wall of the storage groove 4114.

[0051] Furthermore, when the positioning plate 4111 is pushed out, pressing both ends of the pipe fitting into the grooves of the pipe fitting clamping block 417, the pressing plate 4116 can also deflect downward under the action of the torsion spring 4115, so that one end of the pressing plate 4116 presses against the upper surface of the pipe fitting, further improving the installation effect at both ends of the pipe fitting, avoiding residual gaps between the positioning plate 4111 and the pipe fitting, further ensuring the stability of the pipe fitting during bending, preventing the pipe fitting from popping out during bending, and ensuring work safety.

[0052] Please see Figure 4 An adjusting motor 32 is fixedly installed on one side of the outer wall of the first electric lifting frame 36. A mounting bracket 31 is fixedly installed at one end of the output shaft of the adjusting motor 32. A pushing cylinder 33 is fixedly installed on one side of the outer wall of the mounting bracket 31. A wheel frame 34 is fixedly installed at one end of the output shaft of the pushing cylinder 33. A bending wheel 35 is rotatably installed on the inner side of the wheel frame 34 via a rotating shaft. Multiple extrusion wheels 313 with different diameters are fixedly installed on the inner side of the bending wheel 35.

[0053] Furthermore, during pipe bending, multiple pipes can be simultaneously installed on different bending mechanisms 3. By controlling the motor 8 to turn on, the drive bevel gear 9 rotates, which in turn drives multiple driven bevel gears 37 on the outside to rotate synchronously, thereby driving the threaded column 312 to rotate synchronously, which in turn drives multiple sets of bending mechanisms 3 to move synchronously, so that multiple bending wheels 35 can simultaneously perform bending processing on multiple sets of pipes. During bending, the height of the first electric lifting frame 36 can also be adjusted in real time according to the installation height of the pipe, so that the bending wheel 35 is located at the center bending height of the pipe, enabling the bending wheel 35 to stably complete the bending of the pipe. In addition, depending on the curvature requirements at the bending point, the bending wheel 35 can be rotated to adjust the extrusion wheels 313 of different diameters for bending processing.

[0054] The above technical solution can simultaneously complete the bending of multiple sets of pipe fittings, greatly improving the overall working efficiency of the equipment. At the same time, it can also adjust the height of the bending wheel 35 according to the installation position of the pipe fitting to adapt to the bending requirements. Furthermore, it can quickly adjust the extrusion wheel 313 of different diameters according to the curvature requirements of the pipe fitting bending point, further improving the precision of the equipment bending and enhancing the actual application effect of the equipment.

[0055] This invention also discloses a method for using a multi-station synchronous bending and forming equipment for automotive seat frame tubing, comprising the following steps:

[0056] S1. When installing the skeleton pipe fittings, first install the pipe fittings. First, adjust the distance between the two sets of installation mechanisms 4 according to the overall length of the pipe fittings. Then, directly turn on the installation motor 45 to control the rotation of the bidirectional screw 46, thereby controlling the synchronous displacement of the two sets of installation mechanisms 4 to meet the installation requirements of the pipe fittings.

[0057] S2. According to the irregular shape of the pipe fitting, adjust the installation accessory 41 to move outside the installation rail 42 and the rotatable positioning component 411 to meet the installation requirements of the two ends of the pipe fitting. At this time, the two ends of the pipe fitting are respectively inserted into the grooves of the two pipe fitting clamping blocks 417. At this time, the pressing block 4119 is pressed and moves downward, which simultaneously drives the insertion shafts 4117 and the side plates 4118 on both sides to move downward. At this time, one end of the insertion shaft 4117 can be disengaged from the bottom hole 4112 on the bottom surface of the positioning plate 4111. At this time, the built-in spring 4113 is unrestricted and the positioning plate 4111 can be pushed out, pressing the two ends of the pipe fitting into the grooves of the pipe fitting clamping blocks 417 respectively, thus completing the installation of the two ends of the pipe fitting.

[0058] S3. When the positioning plate 4111 is pushed out, pressing the two ends of the pipe fitting into the grooves of the pipe fitting clamp 417, the pressing plate 4116 can also deflect downward under the action of the torsion spring 4115, so that one end of the pressing plate 4116 presses against the upper surface of the pipe fitting, further improving the installation effect of the two ends of the pipe fitting, avoiding the residual gap between the positioning plate 4111 and the pipe fitting, and further ensuring the stability of the pipe fitting when bending.

[0059] S4. When bending pipe fittings, multiple pipe fittings can be installed on different bending mechanisms 3 simultaneously. By controlling the motor 8 to turn on, the drive bevel gear 9 is driven to rotate. The drive bevel gear 9 can drive multiple driven bevel gears 37 on the outside to rotate synchronously, thereby driving the threaded column 312 to rotate synchronously, thereby driving multiple sets of bending mechanisms 3 to move synchronously, so that multiple bending wheels 35 can simultaneously achieve the bending of multiple sets of pipe fittings.

[0060] S5. During bending, the height of the first electric lifting frame 36 can be adjusted in real time according to the installation height of the pipe fitting, so that the bending wheel 35 is located at the center bending height of the pipe fitting, so that the bending wheel 35 can stably complete the bending of the pipe fitting. In addition, depending on the curvature requirements at the bending point, the bending wheel 35 can be rotated to adjust the extrusion wheel 313 of different diameters for bending processing.

[0061] Working principle:

[0062] When installing the skeleton pipe fitting, the pipe fitting is installed first. According to the overall length of the pipe fitting, the distance between the two sets of installation mechanisms 4 is adjusted. The installation motor 45 is directly turned on to control the rotation of the bidirectional screw 46, thereby controlling the synchronous displacement of the two sets of installation mechanisms 4 to meet the installation requirements of the pipe fitting. According to the irregular shape of the pipe fitting, the installation accessory 41 is adjusted to move outside the installation rail 42 and the overall positioning component 411 can be rotated to meet the installation requirements of the two ends of the pipe fitting. At this time, the two ends of the pipe fitting are respectively inserted into the grooves of the two pipe fitting clamping blocks 417. At this time, the pressing block 4119 is pressed downward, which synchronously drives the insertion shaft 4117 and the side plate 4118 on both sides to move downward. At this time, one end of the insertion shaft 4117 can be disengaged from the bottom hole 4112 on the bottom surface of the positioning plate 4111. At this time, the built-in spring 4113 is unrestricted and the positioning plate 4111 can be pushed out, pressing the two ends of the pipe fitting into the grooves of the pipe fitting clamping blocks 417, thus completing the installation of the two ends of the pipe fitting.

[0063] When the positioning plate 4111 is pushed out, pressing both ends of the pipe fitting into the grooves of the pipe fitting clamp 417, the pressing plate 4116 can also deflect downward under the action of the torsion spring 4115, so that one end of the pressing plate 4116 presses against the upper surface of the pipe fitting, further improving the installation effect of both ends of the pipe fitting, avoiding residual gaps between the positioning plate 4111 and the pipe fitting, and further ensuring the stability of the pipe fitting when bending.

[0064] When bending pipe fittings, multiple pipe fittings can be installed on different bending mechanisms 3 simultaneously. By controlling the motor 8 to turn on, the drive bevel gear 9 is driven to rotate. The drive bevel gear 9 can drive multiple driven bevel gears 37 on the outside to rotate synchronously, thereby driving the threaded column 312 to rotate synchronously, thereby driving multiple sets of bending mechanisms 3 to move synchronously, so that multiple bending wheels 35 can simultaneously perform bending processing on multiple sets of pipe fittings. During bending, the height of the first electric lifting frame 36 can also be adjusted in real time according to the installation height of the pipe fitting, so that the bending wheel 35 is located at the center bending height of the pipe fitting, so that the bending wheel 35 can stably complete the bending of the pipe fitting. In addition, according to the different requirements of the curvature at the bending point, the bending wheel 35 is rotated to adjust the extrusion wheel 313 of different diameters for bending processing.

[0065] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.

10. The method of using the multi-station synchronous bending and forming equipment for automotive seat frame tubing according to any one of claims 1-9, characterized in that, Includes the following steps: S1. When installing the skeleton pipe fittings, first install the pipe fittings. First, adjust the distance between the two sets of installation mechanisms (4) according to the overall length of the pipe fittings. Then, directly turn on the installation motor (45) to control the bidirectional screw (46) to rotate, thereby controlling the synchronous displacement of the two sets of installation mechanisms (4) to meet the installation requirements of the pipe fittings. S2. According to the irregular shape of the pipe fitting, adjust the installation accessories (41) to move outside the installation rail (42) and rotate the overall positioning component (411) to meet the installation requirements of the two ends of the pipe fitting. At this time, the two ends of the pipe fitting are respectively inserted into the grooves of the two pipe fitting blocks (417). At this time, the pressing block (4119) is pressured and moves downward, which synchronously drives the insert shaft (4117) and the side plate (4118) on both sides to move downward. At this time, one end of the insert shaft (4117) can be separated from the bottom hole (4112) on the bottom surface of the positioning plate (4111). At this time, the built-in spring (4113) is unrestricted and the positioning plate (4111) can be pushed out, and the two ends of the pipe fitting are pressed into the grooves of the pipe fitting blocks (417) to complete the installation of the two ends of the pipe fitting. S3. When the positioning plate (4111) is pushed out, pressing the two ends of the pipe fitting into the groove of the pipe fitting clamp (417), the extrusion plate (4116) can also deflect downward under the action of the torsion spring (4115), so that one end of the extrusion plate (4116) extrudes the upper surface of the pipe fitting, further improving the installation effect of the two ends of the pipe fitting, avoiding the residual gap between the positioning plate (4111) and the pipe fitting, and further ensuring the stability of the pipe fitting when bending. S4. When bending pipe fittings, multiple pipe fittings can be installed on different bending mechanisms (3) at the same time. By controlling the motor (8) to turn on, the driving bevel gear (9) is driven to rotate. The driving bevel gear (9) can drive multiple driven bevel gears (37) on the outside to rotate synchronously, thereby driving the threaded column (312) to rotate synchronously, thereby driving multiple sets of bending mechanisms (3) to move synchronously, so that multiple bending wheels (35) can simultaneously realize the bending of multiple sets of pipe fittings. S5. During bending, the height of the first electric lifting frame (36) can be adjusted in real time according to the installation height of the pipe fitting, so that the bending wheel (35) is located at the center bending height of the pipe fitting, so that the bending wheel (35) can stably complete the bending of the pipe fitting. According to the different requirements of the curvature at the bending point, the bending wheel (35) can be rotated to adjust the extrusion wheel (313) of different diameters for bending.
