This change is not only reflected in the higher requirements for material performance and manufacturing process, but also deeply reflected in the growing demand for special-shaped pipe fittings. As an important part of automobile interior, the comfort, safety and lightweight design of automobile seats are directly related to the passenger's riding experience and the energy efficiency performance of the whole vehicle. Special-shaped pipe fittings, with their unique cross-sectional shape, high strength, light weight, good plasticity and corrosion resistance, have become the key material for improving seat performance. They are not only widely used in the support and reinforcement of seat frames to ensure the stability and durability of seat structures, but also through optimized design and precision manufacturing, they meet the stringent requirements of seats in terms of adjustment flexibility, collision safety and ergonomics.

[0003] The traditional special-shaped tube forming device has relatively limited functions and can often only perform cold rolling and pressing on a single type of special-shaped tube. This limitation greatly restricts production efficiency and flexibility. Because in actual applications, the specifications and models of special-shaped tubes are varied, and different engineering projects often require the use of special-shaped tubes of different sizes and shapes. In order to improve production efficiency and flexibility, reduce production costs, and adapt to the diverse needs of the market, there is an urgent need for a special-shaped tube forming device for automotive seats.

[0008] When welding is required, the first motor can be started to drive gear four, which in turn drives gear two and gear three to rotate, and gear two drives gear one. Rack one and rack two are provided at the tops of clamping blocks one and two. Rack one is meshed with gear one, and can be moved laterally by rotating gear one. Rack two is meshed with gear three, and can be moved laterally by rotating gear three. When the two clamping blocks move laterally inward at the same time, clamping can be achieved to fix the special-shaped pipe to prevent shaking or rotation during welding that may cause the welding point to shift.

[0009] Preferably, a slide groove 1 is provided on the surface of the clamping block 1, and the inner wall of the slide groove 1 is slidably connected to the slide rail 1. A slide groove 2 is provided on the surface of the clamping block 2, and the inner wall of the slide groove 2 is slidably connected to the slide rail 2.

[0010] The design of the slide groove and the slide rail enables the clamp to slide stably and smoothly, ensuring the accuracy and stability of the clamping action.

[0011] Preferably, the surface of gear four meshes with gear three, the surface of gear four meshes with gear two, and the surface of gear two meshes with gear one.

[0012] The mutual meshing of the gears realizes the transmission and distribution of power, ensuring that the clamping blocks can perform the clamping action synchronously and harmoniously.

[0013] Preferably, a rack 1 is provided at the top of the clamping block 1, and the rack 1 is meshed with a gear 1; a rack 2 is provided at the top of the clamping block 2, and the rack 2 is meshed with a gear 3.

[0014] The meshing action of the rack and the gear is to convert the rotational motion of the gear into the linear motion of the clamping block, so as to achieve the precise clamping and release of the clamping block.

[0015] Preferably, the surface of the sliding block is slidably connected to the inner wall of the second mounting frame, and the bottom end of the second mounting frame is fixedly connected to the bottom plate.

[0016] The sliding connection between the slider and the second mounting frame ensures the stability of the movement of the clamping block, while the fixed connection between the second mounting frame and the base plate provides a stable support for the entire clamping mechanism.

[0017] The cam is connected with a toothed plate at one end and a toothed plate at the other end of the toothed plate at the other end, and the toothed plate is connected with a toothed plate at one end and a toothed plate at the other end.

[0018] By connecting the connecting block 1 and the connecting block 2 to the driving first motor, the rotating rod 1 and the rotating rod 2 are rotated, thereby driving the installation shaft 1 and the installation shaft 2 to rotate. The installation shaft 1 can drive the transverse mold 1 to rotate, and the installation shaft 2 can drive the transverse mold 2 to rotate, thereby driving the plate to move and realize the pressing and forming of the plate. In addition, when in use, the limit block 1 can be removed from the surface of the rotating rod 1, and the transverse mold 1 and the installation shaft can be replaced by removing the screws fixing the transverse mold 1. Similarly, the limit block 2 can be removed from the rotating rod 2, and the screws between the transverse mold 2 and the installation shaft can be loosened to replace the transverse mold 2, so that the device can install different molds according to different predetermined specifications.

[0019] Preferably, one end of the rotating rod 1 away from the limiting block 1 is fixedly connected to the connecting block 1, and one end of the rotating rod 2 away from the limiting block 2 is fixedly connected to the connecting block 2.

[0020] The connection function of the connecting block and the rotating rod is to transmit the power of driving the first motor to the rotating rod, realize the rotational movement of the rotating rod, and then drive the subsequent forming or clamping mechanism.

[0021] Preferably, the bottom end of the mounting frame 1 is fixedly connected to the base plate, and the surface of the lead screw 1 is threadedly connected to a limiting nut 1.

[0022] The fixed connection between the mounting frame 1 and the base plate provides a stable support for the entire forming mechanism, while the threaded connection between the lead screw 1 and the limit nut 1 is used to adjust the position of the mounting shaft and the cross mold to achieve precise forming control.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] First, when the device is used, the power of the driving motor can be transmitted to the rotating rod 1 and the rotating rod 2 by connecting the connecting block 1 and the connecting block 2 with the driving motor, thereby driving them to rotate. As the rotating rod 1 and the rotating rod 2 rotate, the mounting shaft 1 and the mounting shaft 2 will also rotate accordingly. The rotation of the mounting shaft 1 can drive the transverse mold 1 to rotate, and the rotation of the mounting shaft 2 can drive the transverse mold 2 to rotate. In this way, the plate moves under the drive of the transverse mold 1 and the transverse mold 2, thereby realizing the pressing and forming process of the plate. The design of this pressing and forming device is intended to improve the efficiency and quality of plate production and ensure that the plate can be processed according to predetermined specifications and shapes.

[0025] Second, the user of the present invention can first easily unscrew or remove the limit block 1 from the surface of the rotating rod 1. This step is very important because it ensures the stability and safety of the cross mold 1 during the replacement process and prevents the mold from accidentally moving or falling off during the disassembly process. Once the limit block is safely removed, the user can proceed to loosen the screws fixing the cross mold 1 and the installation shaft 1. These screws usually adopt standard specifications, which are convenient for quick disassembly using common tools. After the screws are completely loosened, the cross mold 1 can be easily removed from the installation shaft 1, preparing for the installation of a new mold. Similarly, for the rotating rod 2 and the cross mold 2 thereon, the user also follows The same steps are followed, that is, first remove the limit block 2 to ensure the safety of the operation, and then loosen the fixing screws between the cross mold 2 and the mounting shaft 2 to achieve the smooth replacement of the cross mold 2. This design enables the device to quickly install different molds according to different predetermined specifications. Whether it is producing round, square, oval or other complex-shaped special-shaped tubes, users only need to select the appropriate mold according to specific needs and replace it according to the above steps. This high degree of flexibility and customizability not only improves the utilization rate of the equipment, but also greatly shortens the production preparation time, providing automotive seat manufacturers with greater production flexibility and market competitiveness.

[0026] Third, when the present invention uses the advanced special-shaped pipe welding equipment, when the production process enters the welding link, the operator only needs to simply start the motor, and the driving force of the motor is effectively transmitted to gear four, gear four, and synchronously drives gear two and gear three that are closely meshed with it. As gear two rotates, its powerful torque is further transmitted to gear one, and gear one has a meshing relationship with rack one at the top of clamp block one. When gear one rotates clockwise or counterclockwise, rack one will move horizontally under its drive, thereby pushing clamp block one to slide smoothly along the preset track. At the same time, the rotation of gear three also drives the clamp block one through its meshing relationship with rack two at the top of clamp block two. The synchronous lateral movement of block 2 ensures that clamping block 1 and clamping block 2 can move inward at the same time and synchronously, and also greatly enhances the stability and reliability of the clamping system. When the two clamping blocks move inward at the same time driven by the motor, they can tightly clamp the special-shaped tube to be welded. This powerful clamping force not only effectively prevents the special-shaped tube from shaking or rotating due to heat during the welding process, but also ensures the precise alignment of the welding point, thereby avoiding the occurrence of quality problems such as welding point offset, providing a stable and reliable clamping force for the welding operation, ensuring the precise alignment of the welding point and the high quality of the welding quality, improving production efficiency, and reducing the difficulty of operation and labor costs.

Similarly, for the rotating rod 2008 and the transverse mold 2014 thereon, the user also follows the same steps, that is, first remove the limit block 2009 to ensure the safety of the operation, and then loosen the fixing screws between the transverse mold 2014 and the installation shaft 2 2016, so as to achieve the smooth replacement of the transverse mold 2 2014. This design enables the device to quickly install different molds according to different predetermined specifications. Whether it is producing round, square, oval or other complex-shaped special-shaped tubes, users only need to select the appropriate mold according to specific needs and replace it according to the above steps. This high degree of flexibility and customizability not only improves the utilization rate of the equipment,It also greatly shortens the production preparation time, providing automobile seat manufacturers with greater production flexibility and market competitiveness. When in use, the limit block 2005 can be removed from the surface of the rotating rod 2004, and then the screws fixing the transverse mold 2013 and the installation shaft 2015 can be removed to replace the transverse mold 2013. Similarly, the limit block 2009 can be removed from the rotating rod 2008, and then the screws between the transverse mold 2014 and the installation shaft 2016 can be unfastened to replace the transverse mold 2014, so that the device can install different molds according to different predetermined specifications. In the process of forming the special-shaped tube, the shape of the special-shaped tube can be limited at multiple levels by setting multiple groups of processing mechanisms 1 and fixing units 30, so that it can be gradually formed into a predetermined specification shape;

[0052] In addition, due to the front plate of the special-shaped tube forming, when the shape of the special-shaped tube meets the predetermined specifications, the special-shaped tube needs to be welded, and the production process enters the welding stage. The operator only needs to simply start the first motor 3012. The driving force of the first motor 3012 is effectively transmitted to the gear four 3022, and synchronously drives the gear two 3019 and the gear three 3021 that are closely meshed with it. As the gear two 3019 rotates, its powerful torque is further transmitted to the gear one 3017. The gear one 3017 has a meshing relationship with the rack one at the top of the clamp block one 3014. When the gear one 3017 rotates clockwise or counterclockwise, the rack one will realize lateral movement under its drive, thereby pushing the clamp block one 3014 to slide smoothly along the preset track. At the same time, the rotation of the gear three 3021 is also achieved through its interaction with the rack two at the top of the clamp block two 3015. The meshing relationship drives the second clamping block 3015 to move laterally synchronously, ensuring that the first clamping block 3014 and the second clamping block 3015 can move inward simultaneously and synchronously, and also greatly enhances the stability and reliability of the clamping system. When the two clamping blocks move inward laterally at the same time driven by the first motor 3012, they can tightly clamp the special-shaped tube to be welded. This powerful clamping force not only effectively prevents the special-shaped tube from shaking or rotating due to heat during the welding process, but also ensures the precise alignment of the welding point, thereby avoiding the occurrence of quality problems such as welding point offset, providing a stable and reliable clamping force for the welding operation, ensuring the precise alignment of the welding point and the high quality of the welding quality, improving production efficiency, and reducing the difficulty of operation and labor costs. After the welding is completed, the special-shaped tube can be finally processed by setting a grinding component and a cutting component.
