Technical Field
[0001] The utility model relates to the field of stamping machines, in particular to a bending angle adjusting device. Background Technique
[0002] Stamping is a forming process method that relies on a press and a die to apply external force to profiles and the like, causing plastic deformation to obtain workpieces (stamped parts) with the required shape and size. Among them, the bending generated by the pressed parts refers to the process in which metal materials are plastically deformed by extrusion between the upper die and the lower die of a bending machine and finally form a bent state.
[0003] When the existing bending machine bends a workpiece, it will use the upper die or the lower die of the bending machine to approach and generate extrusion force, causing a certain deformation of the workpiece. However, the outer part of the bent part of the workpiece does not receive the deformation pressure at the same time, resulting in the two ends of the workpiece not fully conforming to the preset bending angle. Subsequently, the staff needs to perform secondary angle adjustment treatment, which is very troublesome and time-consuming.
[0004] Therefore, it is necessary to provide a new bending angle adjusting device to solve the above technical problems. Content of the Utility Model

[0023] It should be noted that: the two convex shafts 32 at the lower end of the adjustment block 31 rotate relative to the two convex seats 3, and at the same time, the return spring 33 is compressed and deformed, so that the adjustment block 31 can stably rotate and fit the external position of the workpiece and perform extrusion treatment, and the bending angle of the workpiece can be automatically adjusted by the adjustment block 31 after the bending is completed.
[0024] Refer to Figure 1 shown, the driving component includes a positioning seat 4, one end of the positioning seat 4 is fixedly connected to the bed base 1, two sliding rods 41 are provided on the positioning seat 4, a wedge block 42 is fixedly connected to the top ends of the two sliding rods 41, a vertical top head 43 is fixedly connected to the lower ends of the two sliding rods 41 together, and vertical springs 44 are sleeved on both of the two sliding rods 41.
[0025] Refer to Figure 1 and Figure 2 shown, two sliding openings are provided on the positioning seat 4, the two sliding rods 41 are respectively slidably connected to the two sliding openings, the lower ends of the vertical top head 43 and the upper end of the adjustment block 31 are both designed with arc-shaped heads, and the vertical top head 43 is arranged above the adjustment block 31.
[0026] It should be noted that: The wedge block 42 drives the two slide bars 41 to slide relative to the positioning seat 4, causing elastic deformation of both vertical springs 44. The two vertical springs 44 can ensure the subsequent normal reset movement of the wedge block 42;
[0027] The two slide bars 41 simultaneously drive the vertical top head 43 to move downward, and the arc head at the lower end of the vertical top head 43 drives the arc head of the adjustment block 31 to move, causing the two convex shafts 32 at the lower end of the adjustment block 31 to rotate relative to the two convex seats 3.
[0028] Reference Figure 1 As shown, one end of each of the two vertical springs 44 is connected to the positioning seat 4, and the other end of each of the two vertical springs 44 is connected to the wedge block 42.
[0029] Reference Figure 1 and Figure 3 As shown, a push position bevel head plate 5 is provided above the positioning seat 4. The head position of the push position bevel head plate 5 is wedge-shaped, and the push position bevel head plate 5 is aligned with the wedge block 42.
[0030] It should be noted that: The synchronous structure on the punching machine structure drives the push position bevel head plate 5 to move synchronously, causing the head of the push position bevel head plate 5 to move and abut against the wedge block 42 at the top end of the vertical top head 43, serving as the synchronous driving force for adjusting the deformation.
[0031] Reference Figure 1 and Figure 3 As shown, an inclined stop seat 6 is provided at the rear position of the adjustment block 31, and a rubber pad 61 is installed and connected to the seat surface of the inclined stop seat 6.
[0032] It should be noted that: When the push position bevel head plate 5 moves and resets, the reset spring 33 restores elastic deformation, causing the adjustment block 31 to rotate in the reverse direction and reset.

[0034] The working principle of a bending angle adjusting device provided by the present utility model is as follows: The synchronous structure (prior art) of the punching machine structure drives the pushing inclined head plate 5 to move, so that the head of the pushing inclined head plate 5 moves to abut against the wedge block 42 at the top end of the vertical top head 43, causing the wedge block 42 to drive the two slide rods 41 to slide relative to the positioning seat 4, causing the two vertical springs 44 to undergo elastic deformation. The two slide rods 41 simultaneously drive the vertical top head 43 to move downward. The arc head at the lower end of the vertical top head 43 drives the arc head of the adjusting block 31 to move, causing the two convex shafts 32 at the lower end of the adjusting block 31 to rotate relative to the two convex seats 3, and the return spring 33 is compressed and deformed, causing the adjusting block 31 to rotate and fit the external position of the workpiece, thereby realizing the automatic adjustment of the bending angle of the workpiece by the adjusting block 31 after the bending is completed.
[0035] When the pushing inclined head plate 5 moves and resets, the return spring 33 restores elastic deformation, causing the adjusting block 31 to rotate reversely and reset. The adjusting block 31 rotates and fits the rubber pad 61 on the inclined baffle seat 6. The inclined baffle seat 6 can ensure that the adjusting block 31 can be quickly and stably reset without excessive shaking, thus avoiding affecting the next adjustment operation.
