[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-5As shown, this utility model is a bending device for an automotive sunroof guide rail, including a base 1, a housing 2 on top of the base 1, a support frame 3 on one side of the base 1, a first servo cylinder 4 fixedly mounted on the middle of the upper part of the support frame 3, the stroke end of the first servo cylinder 4 passing through the support frame 3 and fixedly connected to a connecting block 5, the side of the connecting block 5 away from the support frame 3 being fixedly connected to a mounting frame 6. When the first servo cylinder 4 is working, it pushes the connecting block 5 to move horizontally, causing the mounting frame 6 to move accordingly through the transmission of the connecting block 5. Multiple second servo cylinders 7 are arranged at equal intervals above the mounting frame 6, and multiple first guide sleeves 8 are arranged at equal intervals at the lower end of the mounting frame 6. A push rod 9 is inserted into the middle of the first guide sleeve 8, and the push rod 9 is movably connected to the first guide sleeve 8, allowing the push rod 9 to move vertically inside the first guide sleeve 8. The stroke end of the second servo cylinder 7 passes through the mounting frame 6 and is fixedly connected to the push rod 9, the lower part of the push rod 9 being fixedly connected to a forming mold 10. When the second servo cylinder 7 is working, it pushes the push rod 9 to move vertically. The push rod 9 then moves the forming mold 10 accordingly. The mounting bracket 6 has first cylinders 11 on both sides of its upper end. The stroke end of the first cylinder 11 passes through the mounting bracket 6 and is fixedly connected to the upper cavity plate 12. The stroke end of the first cylinder 11 and the upper cavity plate 12 can be disassembled, making it easier to replace the upper cavity plate 12 when bending different types of guide rails. During operation, the first cylinder 11 can adjust the position of the upper molded cavity plate 12. The lower end of the base 1 is provided with a lower molding mechanism moving assembly 13. Above the lower molding mechanism moving assembly 13, there are multiple equally spaced fixed seats 14. The lower molded cavity plate 15 is provided in the multiple fixed seats 14. The lower molding mechanism moving assembly 13 can adjust the position of the lower molded cavity plate 15. The lower molded cavity plate 15 is snapped into the fixed seat 14, so that the lower molded cavity plate 15 can be stably installed above the lower molding mechanism moving assembly 13.

[0020] The lower molding mechanism moving assembly 13 includes a support plate 131, which is fixedly connected to the base 1. The support plate 131 is provided with a plurality of second cylinders 132 arranged at equal intervals. The stroke end of the second cylinder 132 is fixedly connected to the first connecting plate 133. The upper part of the first connecting plate 133 is movably connected to the fixed seat 14 through a pin. When the second cylinder 132 is working, the second cylinder 132 can push the first connecting plate 133 to move vertically. Through the transmission of the first connecting plate 133, the position of the lower cavity plate 15 can be adjusted. The first connecting plate 133 is movably connected to the fixed seat 14, so that the fixed seat 14 can position the lower cavity plate 15 with different curvatures.

[0021] The upper end of the second cylinder 132 is provided with a fixing plate 134. The fixing plate 134 is provided with second guide sleeves 135 on both sides of the second cylinder 132. A guide rod 136 is inserted into the middle of the second guide sleeve 135. The upper part of the guide rod 136 is fixedly connected to the first connecting plate 133. The guide rod 136 and the second guide sleeve 135 are movably connected. Through the mutual cooperation between the guide rod 136 and the second guide sleeve 135, the movement stability of the first connecting plate 133 is effectively improved.

[0022] The upper end of the mounting frame 6 is provided with a second connecting plate 16 that matches the push rod 9. The side of the second connecting plate 16 away from the mounting frame 6 is fixedly connected to the electronic ruler 17. The measuring end of the electronic ruler 17 is fixedly connected to the connecting rod 19. The mounting frame 6 is provided with a clearance groove 18 that matches the lower end of the electronic ruler 17. The connecting rod 19 passes through the clearance groove 18 and is fixedly connected to the push rod 9. When the push rod 9 moves, the push rod 9 drives the measuring end of the electronic ruler 17 to move through the connecting rod 19. Thus, the electronic ruler 17 can accurately measure the position change of the push rod 9 in real time, and accurately feed back the position information of the forming mold 10. At the same time, the electronic ruler 17 can save the measured data and display it through the CNC panel 23. Through the saving of the electronic ruler 17, when the bending equipment is bending the same type of sunroof guide rail, it can be directly controlled through the CNC panel 23, thereby effectively improving the processing efficiency of the bending equipment for guide rails of different sizes.

[0023] The mounting frame 6 is provided with sliders 20 at both ends near the support frame 3. The support frame 3 is provided with guide rails 21 that match the sliders 20. The sliders 20 can slide on the guide rails 21. Through the cooperation between the sliders 20 and the guide rails 21, the movement stability of the mounting frame 6 is effectively improved.

[0024] The upper end of the housing 2 is provided with a mounting rod 22, and the end of the mounting rod 22 away from the housing 2 is fixedly connected to a CNC panel 23. The CNC panel 23 is used by the operator to input various control parameters to realize the automated control of the equipment, improve production efficiency and operation convenience.

[0025] Specifically, in this utility model, when the first servo cylinder 4 is working, it pushes the connecting block 5 to move horizontally. The connecting block 5 causes the mounting frame 6 to move accordingly, allowing the height of the upper forming mechanism of the bending device to be adjusted. When the second servo cylinder 7 is working, it pushes the push rod 9 to move vertically. The push rod 9 causes the forming mold 10 to move accordingly, limiting the inner arc surface of the upper cavity plate 12 and preventing changes in the arc of the upper cavity plate 12 during operation. When the first cylinder 11 is working, it adjusts the position of the upper cavity plate 12, ensuring that the upper cavity plate 12 is tightly aligned with the forming mold 10. The mold 10 fits together, and the stroke end of the first cylinder 11 can be detached from the upper cavity plate 12, making it easier to replace the upper cavity plate 12 when bending different types of guide rails. When the second cylinder 132 is working, the second cylinder 132 can push the first connecting plate 133 to move vertically. Through the transmission of the first connecting plate 133, the position of the lower cavity plate 15 can be adjusted. The first connecting plate 133 is movably connected to the fixed seat 14, so that the fixed seat 14 can position the lower cavity plate 15 with different curvatures. The first servo electric cylinder 4 adjusts the height of the upper forming mechanism, and the lower forming mechanism moving component 13 adjusts the height of the lower cavity plate 15. Through the mutual cooperation between the upper cavity plate 12 and the lower cavity plate 15, the bending of the sunroof guide rail can be completed.
