Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, specifically to a sheet metal bending auxiliary positioning mechanism. Background Technology

[0002] Sheet metal parts refer to components made from metal sheets through processes such as cutting, stamping, bending, and welding. Sheet metal processing is commonly used to manufacture components such as shells, brackets, and frames in various fields such as machinery, electronic equipment, automobiles, and aerospace.

[0003] A sheet metal bending machine is a piece of equipment used for processing sheet metal parts. It mainly uses molds and pressure to bend metal sheets into the required angles and shapes. Sheet metal bending machines are very important in sheet metal processing, as they can improve production efficiency, ensure processing accuracy, and adapt to diverse production needs. In the processing of sheet metal parts, positioning is a key step to ensure processing accuracy and workpiece consistency. Correct positioning not only ensures the accuracy of the bending angle of each sheet metal part, but also improves production efficiency and reduces material waste.

[0004] In the existing technology, sheet metal bending positioning usually involves a customized block tool placed on a workbench to fix the sheet metal part in a specific position. The operator manually adjusts the position of the workpiece to ensure the accuracy of the bending angle. Manual positioning relies on the experience and operating skills of the operator and is easily affected by factors such as fatigue and misjudgment, resulting in unstable positioning accuracy.

[0007] The auxiliary disk is equipped with a control lever at the upper end, and a reserved slot is opened at one end of the auxiliary disk. A connecting rod is movably installed on the inner wall of the reserved slot, and one end of the connecting rod is connected to the push plate. A damping shaft is installed at the bottom end of the auxiliary disk, and one end of the damping shaft extends into the interior of the bending machine.

[0008] The bending machine is provided with a mounting bracket at one end, and a pressure plate is movably installed on the inner wall of the mounting bracket. The bending machine is provided with a bending groove at one end, and the pressure plate is suspended above the bending groove.

[0009] By adopting the above technical solution, the problem of workpiece position adjustment is solved. The workpiece is placed on one side of the auxiliary disk, and the operator rotates the auxiliary disk around the damping shaft using a control lever. The rotation angle of the auxiliary disk is observed through marker blocks and angle lines. The rotation of the auxiliary disk drives the workpiece to rotate, thereby changing the workpiece bending angle.

[0017] Preferably, the auxiliary plate slides inside the groove, and the auxiliary plate provides auxiliary fixation for one end of the workpiece.

[0018] The present invention is further configured such that a spring is installed at the bottom end of the slide groove, and one end of the spring is connected to one end of the auxiliary plate.

[0019] Preferably, the spring exerts a pulling force on one end of the auxiliary plate, increasing the pressure of the auxiliary plate on one end of the workpiece.

[0020] The present invention is further provided that the outer wall of the auxiliary plate is covered with a rubber pad layer.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] A sheet metal bending auxiliary positioning mechanism, such as Figure 1 - Figure 6 As shown, it includes a bending machine 1, an auxiliary plate 3 and a push plate 13. The auxiliary plate 3 is movably installed on the upper end of the bending machine 1, and the push plate 13 is movably installed on one side of the auxiliary plate 13.

[0036] The auxiliary disk 3 is equipped with a control lever 5 at its upper end. A reserved groove 10 is opened at one end of the auxiliary disk 3. A connecting rod 11 is movably installed on the inner wall of the reserved groove 10, and one end of the connecting rod 11 is connected to the push plate 13. A damping shaft 4 is installed at the bottom of the auxiliary disk 3, and one end of the damping shaft 4 extends into the interior of the bending machine 1. An angle line 6 is provided at the upper end of the auxiliary disk 3. A marking block 17 that cooperates with the angle line 6 is provided at the upper end of the bending machine 1. The operator rotates the auxiliary disk 3 around the damping shaft 4 by controlling the control lever 5, and observes the rotation angle of the auxiliary disk 3 by the marking block 17 and the angle line 6. The rotation of the auxiliary disk 3 drives the workpiece to rotate, thereby changing the bending angle of the workpiece.

[0037] One end of the bending machine 1 is provided with a mounting bracket 18, and a pressure plate 21 is movably installed on the inner wall of the mounting bracket 18. One end of the bending machine 1 is provided with a bending groove 2, and the pressure plate 21 is suspended above the bending groove 2. The pressure plate 21 performs bending processing on one end of the workpiece.

[0038] Please see Figure 1 - Figure 6 A hydraulic pump 19 is installed on the upper end of the mounting bracket 18. A hydraulic column 20 is installed at the output end of the hydraulic pump 19, and one end of the hydraulic column 20 is connected to the pressure plate 21. When the hydraulic pump 19 is started, the hydraulic column 20 is pushed to move downward, thereby causing the pressure plate 21 to move downward.

[0039] Please see Figure 3 - Figure 4The auxiliary disk 3 has a drive shaft 8 installed inside. The drive shaft 8 extends to one end of the outer wall of the auxiliary disk 3 and a torsion block 7 is installed thereon. The outer wall of the torsion block 7 is covered with a rubber pad. Rotating the torsion block 7 will drive the drive shaft 8 to rotate.

[0040] Please see Figure 3 - Figure 4 A transmission gear 9 is installed at the bottom of the transmission shaft 8, and a toothed plate 12 is installed on the outer wall of the connecting rod 11. The toothed plate 12 is meshed with the transmission gear 9. When the transmission shaft 8 rotates, it drives the transmission gear 9 to rotate. Since the transmission gear 9 is meshed with the toothed plate 12, the toothed plate 12 is displaced, which in turn drives the connecting rod 11 to be displaced.

[0041] Please see Figure 2 - Figure 5 A groove 14 is provided on one side of the outer wall of the push plate 13. An auxiliary plate 16 is movably installed on one side of the push plate 13, and one end of the auxiliary plate 16 extends into the groove 14. The auxiliary plate 13 slides inside the groove 14 and provides auxiliary fixation for one end of the workpiece.

[0042] Please see Figure 2 - Figure 5 A spring 15 is installed at the bottom of the slide 14, and one end of the spring 15 is connected to one end of the auxiliary plate 16. The spring 15 generates a pulling force on one end of the auxiliary plate 16, increasing the pressure of the auxiliary plate 16 on one end of the workpiece.

[0043] Please see Figure 5 The outer wall of the auxiliary plate 16 is covered with a rubber pad, which protects the auxiliary plate 16 and the workpiece.

[0044] The working principle of this utility model is as follows: When the operator performs bending operation on the workpiece through the bending machine 1, the operator pulls the auxiliary plate 16 upward, and then places the workpiece on one side of the auxiliary plate 3. The spring 15 pulls the auxiliary plate 16 downward, and the auxiliary plate 16 assists in fixing one end of the workpiece. Then, the operator rotates the auxiliary plate 3 around the damping shaft 4 with the control lever 5, and observes the rotation angle of the auxiliary plate 3 through the marking block 17 and the angle line 6. The rotation of the auxiliary plate 3 drives the workpiece to rotate, thereby changing the bending angle of the workpiece.

[0045] After the auxiliary disk 3 rotates, the operator rotates the torsion block 7, which drives the transmission shaft 8 to rotate, thereby driving the transmission gear 9 to rotate. The transmission gear 9 meshes with the toothed plate 12, causing the toothed plate 12 to move, which in turn drives the connecting rod 11 to move, and then drives the push plate 13 to move, thus pushing the workpiece to move so that one end of the workpiece moves to the upper end of the bending groove 2. Then, the hydraulic pump 19 is started, pushing the hydraulic column 20 to move downward, thereby driving the pressure plate 21 to move downward. The pressure plate 21 performs bending processing on one end of the workpiece, while the other end of the workpiece is tilted upward. The auxiliary plate 16 applies auxiliary pressure to the other end of the workpiece, improving the stability of the workpiece bending operation and preventing the worker from holding the other end of the workpiece, thus protecting the worker.
