The die material is usually selected from high-strength, wear-resistant, and tough steel to ensure processing stability and service life. When selecting a die, it is necessary to combine the core requirements such as the material characteristics of the workpiece, bending angle, and forming style to match the corresponding die type, thereby achieving precise and efficient sheet metal bending processing.

[0033] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Reference Figures 1 to 4This application provides a bending side positioning auxiliary device for a bending die, including a worktable 1. A die assembly 2 is fixedly installed on the top of the worktable 1, and the bottom of the worktable 1 is connected to the die assembly 2 via bearings. The die assembly 2 includes a lower die 21 and an upper die 22. The lower die 21 is fixedly installed on the top of the worktable 1, and the upper die 22 is positioned above the lower die 21. A reinforcing assembly 4 is fixedly installed on the inner bottom wall of the worktable 1. A positioning auxiliary assembly 3 includes a threaded rod 31 and a lifting plate 32. The threaded rod 31 is connected to the bottom of the worktable 1 via bearings, and the lifting plate 32 is threadedly connected to the side wall of the threaded rod 31. Connecting rods 33 are hinged to both sides of the lowering plate 32. A moving plate 34 is hinged to one end of the connecting rod 33. A slide groove 35 is provided on the top of the workbench 1. The moving plate 34 is slidably connected to the slide groove 35. A rectangular plate 36 is fixedly installed on the top of the moving plate 34. The positioning auxiliary component 3 also includes a stabilizing frame 37. The stabilizing frame 37 is fixedly installed on both sides of the mold component 2. The rectangular plate 36 is slidably connected to the stabilizing frame 37. The positioning auxiliary component 3 also includes a centering plate 38. The centering plate 38 is fixedly installed on one side of the rectangular plate 36. The positioning auxiliary component 3 also includes a knob 39. The knob 39 is fixedly connected to the bottom end of the threaded rod 31.

[0035] In this embodiment, the operator rotates the knob 39 at the bottom of the threaded rod 31. Because the threaded rod 31 is connected to the bottom of the workbench 1 through a bearing, the knob 39 drives the threaded rod 31 to rotate synchronously. The lifting plate 32 is connected to the side wall of the threaded rod 31 through a thread. The rotation of the threaded rod 31 is converted into the axial linear motion of the lifting plate 32. The connecting rods 33 hinged on both sides of the lifting plate 32 change their angle as it moves, pushing the hinged moving plate 34 to slide along the slide groove 35 on the top of the workbench 1. The rectangular plate 36 on the top of the moving plate 34 moves synchronously, and the rectangular plate 36... The 6 is slidably connected to the stabilizing frame 37 on both sides of the mold assembly 2. The stabilizing frame 37 restricts the offset. When the rectangular plate 36 moves into place, the centering plate 38 on one side of it fits against the side of the workpiece to achieve bending side positioning, avoid lateral offset of the workpiece, and lay the foundation for bending accuracy. In the mold assembly 2, the lower mold 21 is fixed to the top of the worktable 1 as a support reference. The upper mold 22 moves downward under the action of external driving force, and applies pressure to the positioning workpiece on the lower mold 21, so that it plastically deforms along the preset trajectory. In this case, the thread helix angle is less than or equal to the equivalent friction angle.

[0036] Reference Figures 1 to 4In one aspect of this embodiment, the reinforcement component 4 includes a reinforcement plate 41 and a connecting plate 42. The reinforcement plate 41 is disposed on one side of the workbench 1, and the connecting plate 42 is fixedly installed on both sides of the workbench 1. A connecting frame 43 is fixedly installed on the inner side wall of the workbench 1. The connecting plate 42 and the connecting frame 43 are interlocked. The reinforcement component 4 also includes a locking plate 44 and a locking groove 45. The locking plate 44 is fixedly installed on both sides of the connecting plate 42, and the locking groove 45 is opened on the top of the connecting frame 43. The locking plate 44 and the locking groove 45 are interlocked. The reinforcement component 4 also includes a screw hole 46 and a screw hole 47. The screw hole 46 is opened on the top of the reinforcement plate 41, and the screw hole 47 is opened on the top of the workbench 1.

[0037] In this embodiment, the reinforcement component 4 enhances the stability of the device. The connecting plates 42 on both sides of the workbench 1 are engaged with the slots 45 of the connecting frame 43 through the clamping plate 44 to achieve initial fixation. The reinforcement plate 41 is bolted to the workbench 1 through the screw hole 46 and the screw hole 47 of the workbench 1 to further reinforce the structure of the workbench 1. When the mold assembly 2 is bending, the reinforcement component 4 prevents the workbench 1 and the mold assembly 2 from shifting. The positioning auxiliary component 3 continuously limits the position. The three work together to ensure the bending accuracy of the workpiece and the stability of the device operation.

[0038] Working principle: The operator rotates the knob 39 at the bottom of the threaded rod 31. Since the threaded rod 31 is connected to the bottom of the worktable 1 through the bearing, the knob 39 drives the threaded rod 31 to rotate synchronously. The lifting plate 32 is connected to the side wall of the threaded rod 31 through the thread. The rotation of the threaded rod 31 is converted into the axial linear motion of the lifting plate 32. The connecting rods 33 hinged on both sides of the lifting plate 32 change their angle as it moves, pushing the hinged moving plate 34 to slide along the slide groove 35 on the top of the worktable 1. The rectangular plate 36 on the top of the moving plate 34 moves synchronously, and the rectangular plate 36 is slidably connected to the stabilizing frame 37 on both sides of the mold assembly 2. The stabilizing frame 37 restricts the offset. When the rectangular plate 36 moves into place, the centering plate 38 on one side of it fits against the side of the workpiece, realizing the positioning of the bending side and avoiding the lateral offset of the workpiece, laying the foundation for bending accuracy.

[0039] In mold assembly 2, the lower mold 21 is fixed to the top of the workbench 1 as a support reference. The upper mold 22 moves downward under the action of external driving force, applying pressure to the positioning workpiece on the lower mold 21, causing it to plastically deform along a preset trajectory. At the same time, the reinforcement assembly 4 enhances the stability of the device. The connecting plates 42 on both sides of the workbench 1 are engaged with the slots 45 of the connecting frame 43 through the clamping plates 44 to achieve initial fixation. The reinforcement plate 41 is bolted to the workbench 1 through the screw hole 46 and the screw hole 47 of the workbench 1 to further reinforce the structure of the workbench 1. During the bending operation of the mold assembly 2, the reinforcement assembly 4 prevents the workbench 1 and the mold assembly 2 from shifting. The positioning auxiliary assembly 3 continuously limits the position. The three work together to ensure the bending accuracy of the workpiece and the stability of the device operation.
