Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically to a guiding auxiliary device for cold bending forming of a middle frame. Background Technology

[0002] In the mobile phone manufacturing industry, aluminum alloy frames are widely used due to their excellent properties such as lightweight and high strength. During the processing of aluminum alloy frames for mobile phones, guiding the aluminum alloy sheet is a crucial step. Precise sheet guidance ensures that the frame achieves ideal shape and dimensional accuracy in subsequent processing steps such as cold bending, thereby improving the quality and performance of the mobile phone frame and meeting increasingly stringent mobile phone manufacturing standards. Therefore, researching how to achieve efficient and precise aluminum alloy sheet guidance technology has significant practical implications.

[0003] Currently, there are shortcomings in the guidance of aluminum alloy sheets during the processing of aluminum alloy mid-frames for mobile phones. On the one hand, existing guiding methods often lack flexibility, making it difficult to quickly and accurately adjust to aluminum alloy sheets of different specifications and shapes. This results in poor guiding effects when processing various types of mid-frames, affecting the forming quality of the mid-frame. On the other hand, some guiding devices have poor stability, easily wobbling or shifting during sheet processing, causing deviations in the sheet during cold bending and reducing the product yield. Utility Model Content

[0004] The purpose of this invention is to provide a guiding auxiliary device for cold bending of the middle frame, so as to solve the problem of poor guiding effect in the processing of existing mobile phone aluminum alloy middle frames mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A guide auxiliary device for cold bending of the middle frame includes a base. Two sets of movable sheet metal guide auxiliary mechanisms for processing aluminum alloy middle frames of mobile phones are installed on the top two sides of the base. Servo reduction motors for adjusting the position of the sheet metal guide auxiliary mechanisms are installed at both ends of the base. The top surface of the base is provided with two movable slide grooves located on the same straight line. Each set of movable slide grooves is equipped with a lead screw. The output shafts of the two sets of servo reduction motors are coaxially connected to the ends of the two sets of lead screws, respectively. The plate guiding auxiliary mechanism includes a support base, a rotating motor is installed inside the support base, a rotating shaft coaxially connected to the output shaft of the rotating motor is installed on the top of the support base, and a disc-shaped guide turntable is installed on the rotating shaft. The bottom of the support base is connected to a movable slide block via a connecting column. The movable slide block is slidably engaged with the movable slide groove. The movable slide block has a threaded hole that is threadedly connected to the lead screw.

[0006] Preferably, the cross-section of the movable slide is convex. In the horizontal direction, the convex structure can prevent the movable slide from shifting left and right during the sliding process, ensuring that it moves stably along the predetermined track. In the vertical direction, the structure can prevent the movable slide from jumping up and down, greatly improving the smoothness of the movable slide's movement, thereby ensuring that the sheet metal guiding auxiliary mechanism can move accurately to the designated position, laying the foundation for the precise guidance of the aluminum alloy sheet metal in the future.

[0007] Preferably, each set of movable slides is equipped with bearings at both ends for fixing the lead screw. The bearings are embedded in the base, which can effectively reduce the frictional resistance between the lead screw and the base when the lead screw rotates, reduce energy loss, and at the same time provide stable support and fixation for the lead screw, preventing the lead screw from shaking or deviating during rotation, ensuring the accuracy and stability of the lead screw rotation, so that the movable slide that cooperates with the lead screw can move accurately according to the preset trajectory.

[0008] Preferably, the output shaft of the servo geared motor is plugged into the end of the lead screw, enabling quick assembly and disassembly of the servo geared motor and the lead screw, thus improving the efficiency of equipment assembly and maintenance. Simultaneously, the plugging connection ensures reliable power transmission, allowing the servo geared motor to stably transmit power to the lead screw, ensuring that the lead screw rotates at the expected speed and direction.

[0009] Preferably, the servo geared motor is mounted on the end of the base via a fixed bracket, which can effectively withstand the vibration and force generated by the servo geared motor during operation and ensure the stability of the servo geared motor during operation.

[0010] Preferably, a servo lifting hydraulic cylinder is installed on the bottom surface of the base. By controlling the extension and retraction of the piston rod of the servo lifting hydraulic cylinder, the height of the device can be changed quickly and accurately to adapt to different processing environments and process requirements, thereby improving the applicability and flexibility of the device and meeting the diverse processing needs of mobile phone aluminum alloy frames.

[0011] Preferably, the piston rod of the servo lifting hydraulic cylinder is connected to the center of the bottom surface of the base to improve stability.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this guide auxiliary device for cold bending forming of the middle frame, the lead screw installed in each set of moving slides is coaxially connected to the output shaft of the servo reduction motor. The servo reduction motor can precisely adjust the rotation of the lead screw, thereby controlling the position of the sheet metal guide auxiliary mechanism; two sets of movable sheet metal guide auxiliary mechanisms installed on both sides of the top of the base are used for sheet metal guide auxiliary in the processing of aluminum alloy middle frames for mobile phones; the support base in the sheet metal guide auxiliary mechanism provides installation space for internal rotating motors and other components, and the output shaft of the rotating motor installed in the support base is connected to the top of the support base. The rotating shaft is coaxially connected to the main unit and can drive the rotating shaft to rotate. The disc-shaped guide turntable installed on the rotating shaft can guide the plate during rotation. The bottom of the support base is connected to the movable slide block through the connecting column, which slides in cooperation with the movable slide groove. The screw hole on the movable slide block is connected to the lead screw thread, so that the movable slide block can move along the lead screw in the movable slide groove, thereby driving the entire plate guiding auxiliary mechanism to move. This allows for flexible adjustment of the position to adapt to the processing needs of different plates. At the same time, the servo reduction motors installed at both ends of the base provide power for the rotation of the lead screw, ensuring the accuracy and stability of the adjustment.

[0017] Guiding auxiliary devices for cold bending forming of the middle frame, such as Figures 1-3As shown, the device includes a base 10. Two movable sheet metal guiding auxiliary mechanisms 30 for processing the aluminum alloy mid-frame of a mobile phone are mounted on both sides of the top of the base 10. Servo reduction motors 20 for adjusting the position of the sheet metal guiding auxiliary mechanisms 30 are mounted at both ends of the base 10. Two sliding grooves 11 located on the same straight line are formed on the top surface of the base 10. A lead screw 12 is installed in each sliding groove 11. The output shafts of the two sets of servo reduction motors 20 are coaxially connected to the ends of the two sets of lead screws 12. The sheet metal guiding auxiliary mechanism 30 includes a support base 31. The support base 31 houses a rotary motor 35. A rotating shaft 33, coaxially connected to the output shaft of the rotary motor 35, is mounted on the top of the support base 31. A disc-shaped guide turntable 32 is mounted on the rotating shaft 33. A movable slide block 40 is connected to the bottom of the support base 31 via a connecting column 34. The movable slide block 40 slides in conjunction with a movable slide groove 11. A threaded hole 41 is provided on the movable slide block 40 for threaded connection with a lead screw 12. The lead screw 12 installed in each set of movable slide grooves 11 is coaxially connected to the output shaft of the servo geared motor 20, allowing for precise adjustment of the servo geared motor 20. The rotation of the lead screw 12 controls the position of the sheet metal guiding auxiliary mechanism 30; two sets of movable sheet metal guiding auxiliary mechanisms 30 are installed on both sides of the top of the base 10 for sheet metal guiding assistance in the processing of mobile phone aluminum alloy mid-frames; the support base 31 in the sheet metal guiding auxiliary mechanism 30 provides installation space for internal rotating motors 35 and other components; the rotating motor 35 installed in the support base 31 has its output shaft coaxially connected with the rotating shaft 33 installed on the top of the support base 31, which can drive the rotating shaft 33 to rotate; the disc-shaped guide turntable 32 installed on the rotating shaft 33 rotates... During the process, the sheet metal can be guided; the bottom of the support base 31 is connected to the movable slide 40 via the connecting column 34, which slides in cooperation with the movable slide groove 11. The screw hole 41 on the movable slide 40 is threaded to the lead screw 12, allowing the movable slide 40 to move along the lead screw 12 within the movable slide groove 11, thereby driving the entire sheet metal guiding auxiliary mechanism 30 to move, achieving flexible position adjustment to adapt to different sheet metal processing requirements. At the same time, the servo reduction motors 20 installed at both ends of the base 10 provide power for the rotation of the lead screw 12, ensuring the accuracy and stability of the adjustment.

[0018] It is worth noting that the cross-section of the movable slide 11 is convex, which allows the movable slide 40 to be better limited when sliding within the movable slide 11, preventing the movable slide 40 from wobbling up and down or detaching from the movable slide 11 during the sliding process, thus ensuring the stability of the plate guiding auxiliary mechanism 30.

[0019] Furthermore, each set of movable slide grooves 11 has bearings installed at both ends for fixing the lead screw 12. The bearings are embedded in the base 10, which makes the lead screw 12 rotate more smoothly, reduces the friction when the lead screw 12 rotates, and also plays a good role in fixing the lead screw 12, ensuring that the lead screw 12 will not deviate during rotation, thus improving the accuracy and stability of the lead screw 12 rotation.

[0020] Specifically, the output shaft of the servo geared motor 20 is plugged into the end of the lead screw 12. The servo geared motor 20 is mounted on the end of the base 10 through the fixing seat 21, which facilitates the assembly and disassembly of the servo geared motor 20 and the lead screw 12. At the same time, the fixing seat 21 can provide stable support for the servo geared motor 20, ensuring the stability of the servo geared motor 20 during operation, thereby ensuring precise control of the rotation of the lead screw 12.

[0021] In addition, a servo lifting hydraulic cylinder 50 is installed on the bottom surface of the base 10. The piston rod of the servo lifting hydraulic cylinder 50 is connected to the center of the bottom surface of the base 10, so that the height of the entire device can be adjusted by the servo lifting hydraulic cylinder 50. The height of the device can be flexibly adjusted according to different processing requirements and working environment, which improves the applicability and flexibility of the device.

[0022] The working principle of the guide auxiliary device for cold bending forming of this middle frame: First, based on the dimensions and processing requirements of the aluminum alloy frame material for the mobile phone, the servo reduction motor 20 is started, and its output shaft drives the lead screw 12 to rotate in the bearings at both ends of the moving slide 11. Since the moving slide 40 is threadedly connected to the lead screw 12 and slides in the moving slide 11, the rotation of the lead screw 12 will drive the moving slide 40 to move along the moving slide 11, and then drive the support base 31 and the entire plate guiding auxiliary mechanism 30 to move to the appropriate position through the connecting column 34. Next, if the height of the device needs to be adjusted, the servo lifting hydraulic cylinder 50 on the bottom surface of the base 10 is activated, and its piston rod extends and retracts to lift the base 10 as a whole to the required height. Then, the sheet material to be processed is placed in a suitable position, and the rotating motor 35 in the support base 31 is started. The output shaft of the rotating motor 35 drives the rotating shaft 33 to rotate, thereby causing the guide turntable 32 on the rotating shaft 33 to rotate. During the sheet material processing, the guide turntable 32 rotates continuously to provide guidance for the sheet material, ensuring that the sheet material is cold-bent and formed according to the predetermined trajectory, thus ensuring the accuracy and quality of the processing.
