[0002] In the automotive manufacturing industry, the structural design of car armrests plays a crucial role in the comfort and safety of drivers and passengers. The processing quality of the armrest's bent tubes directly affects its overall performance and assembly precision. Traditional automotive armrest tube bending processes mostly employ manual or semi-automatic bending equipment, which presents numerous problems.

[0043] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0044] like Figures 1 to 4 As shown, the present invention provides a car armrest bending device, comprising:

[0045] Main support 1, independently set on the ground;

[0046] The feeding mechanism 2 is horizontally slidably mounted on the main support 1 and is used to fix the pipe fittings and push the pipe fittings.

[0047] Bending mechanism 3 is mounted on main support 1 and is used for bending pipe fittings;

[0048] The bending mechanism 3 includes:

[0049] The mounting base 31 is slidably mounted on the main support 1.

[0050] The demolding assembly is mounted on the mounting base 31 to assist in the bending process of the pipe fitting and to help the pipe fitting be demolded after processing;

[0051] The bending shaft 32 is vertically rotatably mounted on the mounting base 31;

[0052] The first moving mold 33 is fixedly mounted on the bending shaft 32 and rotates through the bending shaft 32 for bending the pipe. The bending shaft 32 is driven to rotate by a motor.

[0053] The second moving mold 34 is fixedly mounted on the bending shaft 32. The second moving mold 34 is positioned above the first moving mold 33 and is driven to rotate by the bending shaft 32 for bending the pipe.

[0054] The first fixed mold 35 is set on the demolding assembly and cooperates with the first moving mold 33 to bend the pipe into the corresponding specifications.

[0055] The second fixed mold 36 is set on the demolding assembly and cooperates with the second moving mold 34 to bend the pipe into the corresponding specifications;

[0056] Side fixing plate 37 is fixedly installed on the side end of the main body bracket 1;

[0057] Two side slide rails 38 are vertically arranged on the side fixing plate 37. The mounting base 31 is slidably clamped on the two side slide rails 38. The mounting base 31 is driven to slide up and down by a cylinder.

[0058] The working process and principle of the device are as follows: The pipe to be processed is fixed on the feeding mechanism 2, which is horizontally slidably mounted on the main support 1. According to the preset program or operation instructions, the feeding mechanism 2 accurately pushes the pipe to the processing position of the bending mechanism 3, completing the initial positioning and feeding of the pipe. The mounting base 31 in the bending mechanism 3 is slidably mounted on the main support 1, and is stably guided by the side slide rail 38 on the side fixing plate 37. The mounting base 31 is driven by a cylinder to slide up and down, adjusting to a suitable bending height position. At this time, demolding is performed. The components, first moving mold 33, second moving mold 34, first fixed mold 35, and second fixed mold 36 are all in a standby state, waiting for the pipe to arrive before bending processing. When the pipe is delivered to the bending position, the motor drives the bending shaft 32 to rotate, causing the first moving mold 33 and second moving mold 34, which are fixedly mounted on it, to rotate. The first moving mold 33 cooperates with the first fixed mold 35, and the second moving mold 34 cooperates with the second fixed mold 36 to precisely bend the pipe according to the preset bending parameters, bending the pipe into the corresponding specifications. During the bending process, the demolding component assists in bending the pipe. The processing ensures the pipe remains stable during bending, reducing surface damage and bending angle deviation. The feeding mechanism 2 automatically fixes and pushes the pipe. The mounting base 31 in the bending mechanism 3 slides up and down driven by a cylinder, and the bending shaft 32 rotates driven by a motor. The entire processing is highly automated, reducing manual intervention, significantly shortening the processing cycle, and substantially improving the processing efficiency of automotive armrest pipe bends. This device employs a high-precision positioning and transmission mechanism. The feeding mechanism 2 can accurately push the pipe to the bending position. The first moving mold 3 in the bending mechanism 3... 3. The second moving mold 34 is closely fitted with the first fixed mold 35 and the second fixed mold 36. Through precise mechanical transmission and control system, it ensures that the bending angle and shape of the pipe fittings meet the design requirements, effectively improving processing accuracy and ensuring product consistency. The first moving mold 33, the second moving mold 34, the first fixed mold 35, and the second fixed mold 36 in the bending mechanism 3 can be replaced or adjusted according to different specifications of pipe fittings. With the flexible movement of the feeding mechanism 2 and the mounting base 31, it can achieve efficient processing of various specifications of pipe fittings, improving the versatility and adaptability of the device.

[0059] like Figure 3 As shown, the demolding assembly includes:

[0060] The extension bracket 3a is fixedly connected to the bending shaft 32;

[0061] The unloading cylinder 3b is fixedly mounted on the extension bracket 3a;

[0062] The guide strip 3c is slidably installed in the extension bracket 3a and its sliding is controlled by the unloading cylinder 3b.

[0063] The guide slider 3d is fixedly installed in the extension bracket 3a and slides in conjunction with the guide strip 3c.

[0064] A reinforcing bracket 3e is fixedly installed on the guide strip 3c. A first fixed mold 35 and a second fixed mold 36 are fixedly installed on the reinforcing bracket 3e.

[0065] The working process and principle of the demolding assembly are as follows: After the bending process is completed, the bending shaft 32 stops rotating, and the tube is bent into the corresponding specifications and positioned between the first fixed mold 35 and the second fixed mold 36, as well as the first moving mold 33 and the second moving mold 34. At this time, the ejector cylinder 3b starts to operate, and its piston rod extends or retracts, pushing the guide strip 3c to slide in the extension bracket 3a. Driven by the ejector cylinder 3b, the guide strip 3c slides along the guide block 3d, driving the reinforcing bracket 3e and the first fixed mold 35 and the second fixed mold 36 fixed on it to move. Since there is a certain friction and adsorption force between the tube and the first moving mold 33, the second moving mold 34, the first fixed mold 35, and the second fixed mold 36 after bending, the movement of the reinforcing bracket 3e will change the relative positional relationship between the tube and the mold. The demolding assembly allows the pipe fitting to be smoothly ejected from the mold, completing the demolding process. This automatic demolding mechanism enables the automotive armrest bending device to automatically demold the pipe fitting after bending, eliminating the need for manual assistance, significantly reducing labor intensity, improving production efficiency, and shortening the production cycle. The ejector cylinder 3b drives the guide rail 3c to slide, which in turn moves the reinforcing bracket 3e and the fixed mold. This ensures a smooth and reliable demolding process, avoiding potential damage to the pipe fitting during manual demolding and guaranteeing the surface quality and overall performance of the fitting. The sliding cooperation between the guide slider 3d and the guide rail 3c provides precise guidance for the sliding of the guide rail 3c, ensuring the movement accuracy of the reinforcing bracket 3e and the fixed mold on it. This, in turn, guarantees the positional accuracy of the pipe fitting during demolding, contributing to improved overall pipe bending accuracy.

[0066] A connecting piece 3f is fixedly installed on the extension bracket 3a, and a linkage rod 3g is fixedly installed on the connecting piece 3f. The linkage rod 3g is fixedly connected to the bending shaft 32. The extension bracket 3a and the bending shaft 32 are fixedly connected by the linkage rod 3g, so that the extension bracket 3a and its demolding components can rotate synchronously with the bending shaft 32. This ensures that the relative positional relationship between the first moving mold 33, the second moving mold 34 and the first fixed mold 35, the second fixed mold 36 remains accurate during the bending process, avoiding bending angle deviations caused by relative motion errors between components, thereby improving the bending accuracy of the pipe fitting. The rigid connection method forms a stable integral structure between the extension bracket 3a, the connecting piece 3f, the linkage rod 3g and the bending shaft 32, enhancing the rigidity and stability of the device. During the bending process, it can withstand greater forces and vibrations, reducing deformation and shaking of the device, further ensuring processing quality and the service life of the device.

[0067] like Figure 4 As shown, the feeding mechanism 2 includes:

[0068] The feeding slide plate 21 is horizontally slidably mounted on the top of the main body support 1;

[0069] The feeding screw 22 is rotatably mounted on the top of the main support 1. The feeding screw 22 is threadedly engaged with the feeding slide plate 21, and the feeding screw 22 drives the feeding slide plate 21 to slide horizontally.

[0070] The first motor 23 is fixedly installed on the main support 1, and the first motor 23 drives the feeding screw 22 to rotate.

[0071] The guide tube 24 is set on the feeding slide plate 21 and is used to guide the pipe fitting. The guide tube 24 is equipped with a clamp for clamping the pipe fitting.

[0072] The working process and principle of the feeding mechanism 2 are as follows: The operator places the pipe to be processed into the guide tube 24, and then controls the action of the gripper to clamp the pipe, ensuring that the position of the pipe is stable during the feeding process; the first motor 23 is started, and the first motor 23 starts to rotate, driving the feeding screw 22 to rotate; since the feeding screw 22 is threadedly engaged with the feeding slide plate 21, when the feeding screw 22 rotates, according to the principle of thread transmission, the feeding slide plate 21 will slide horizontally at the top of the main support 1; the feeding slide plate 21 drives the guide tube 24 and the clamped pipe to move together, gradually pushing the pipe to the bending mechanism 3, preparing for the bending process; when the feeding slide plate 21 drives the pipe to the designated position of the bending mechanism 3, the first motor 23 is stopped, the feeding screw 22 stops rotating, the feeding slide plate 21 stops moving, the position of the pipe is fixed, and it waits for the bending mechanism 3 to perform the bending process; after the bending process is completed, the clamping... The claw releases the pipe fitting, and the first motor 23 rotates in the opposite direction, driving the feeding screw 22 to rotate in the opposite direction. The feeding slide plate 21 drives the guide tube 24 back to its initial position, ready for the next feeding. The first motor 23 drives the feeding screw 22 to rotate, realizing the automatic horizontal sliding of the feeding slide plate 21, which quickly and accurately pushes the pipe fitting to the bending mechanism 3, reducing the time and labor intensity of manual operation and greatly improving production efficiency. The threaded engagement between the feeding screw 22 and the feeding slide plate 21 has high transmission precision, which can ensure that the feeding distance is accurate and consistent each time, thereby ensuring the positional accuracy of the pipe fitting in the bending mechanism 3, which is conducive to improving the bending accuracy of the pipe fitting and product consistency. The feeding mechanism 2 adopts a mechanical transmission method, which is stable and reliable in structure. It can maintain the stable position of the pipe fitting during the feeding process, avoiding the shaking and errors caused by manual feeding, and improving the overall stability and reliability of the device.

[0073] Two adjusting slide rails 25 are symmetrically arranged on the feeding slide plate 21. An adjusting slide plate 26 is laterally slidable on the feeding slide plate 21, and the adjusting slide plate 26 is slidably engaged with the adjusting slide rails 25. An adjusting screw 27 is rotatably mounted on the feeding slide plate 21, and the adjusting screw 27 is threadedly engaged with the adjusting slide plate 26 to drive the adjusting slide plate 26 to slide. The guide tube 24 is set on the adjusting slide plate 26. When different specifications of pipe fittings need to be processed, the operator rotates the adjusting screw 27. Since the adjusting screw 27 is threadedly engaged with the adjusting slide plate 26, according to the principle of thread transmission, the rotation of the adjusting screw 27 will drive the adjusting slide plate 26 to slide laterally on the adjusting slide rails 25. The sliding of the adjusting slide plate 26 will drive the guide tube 24 set on it to move together, from... By changing the position of the guide tube 24, it can be adapted to the feeding requirements of different specifications of pipe fittings. Through the cooperation of adjusting screw 27 and adjusting slide plate 26, the position of guide tube 24 can be flexibly adjusted, so that the device can adapt to the feeding requirements of various pipe fittings, greatly improving the versatility and applicability of the device, and reducing the trouble of replacing equipment or adjusting the device due to different pipe fitting specifications. The adjusting slide rail 25 provides a stable guide for the sliding of adjusting slide plate 26, ensuring that the adjusting slide plate 26 is accurately positioned during lateral movement, thereby ensuring the accuracy of the guide tube 24 position adjustment. This helps the pipe fittings to accurately reach the designated position during the feeding process, improving the accuracy and stability of feeding, and is beneficial to the accuracy control of subsequent bending processing.

[0074] A bearing seat 28 is fixedly installed on the adjusting slide plate 26. The guide tube 24 is rotatably mounted on the bearing seat 28. A transmission box is installed on the bearing seat 28, and a second motor 29 is fixedly installed on the bearing seat 28. The second motor 29 drives the guide tube 24 to rotate in the bearing seat 28 through the transmission box. By driving the guide tube 24 to rotate through the second motor 29, the angle of the tube in the feeding direction can be flexibly adjusted, allowing the device to process handrail bends with different angle requirements, greatly improving the processing flexibility of the device and meeting diverse production needs. The bearing seat 28 provides stable support for the rotation of the guide tube 24, reducing the shaking and deviation during the rotation of the guide tube 24, ensuring the accurate position of the tube during rotation, thereby ensuring the accuracy of the tube feeding angle, which is beneficial to the accuracy control of subsequent bending processing and improves the overall quality of the product.

[0075] A handwheel is provided at the end of the adjusting screw 27; the handwheel allows the operator to easily adjust the position of the guide tube 24 by manually rotating it without the need for other tools, which is simple and convenient, reduces the difficulty of operation, and improves work efficiency; the handwheel can provide a large rotational torque, allowing the operator to precisely control the rotation angle and speed of the adjusting screw 27 according to actual needs.

[0076] The main support frame 1 has multiple support feet at its bottom. These support feet evenly distribute the weight of the device, making it more stable when placed. This effectively reduces swaying and tilting caused by uneven ground or external interference, providing a stable platform for feeding, bending, and other processing operations, ensuring processing accuracy and quality.
