[0002] A bending machine is a device used for bending and forming metal sheets. It is widely used in industries such as machinery manufacturing, automobiles, aviation, construction, and home appliances. It applies pressure to cause the metal sheet to undergo plastic deformation under the action of a die, thereby obtaining the desired shape and angle. The problem with the existing technology is that it is not convenient to adjust the position of the die. Most existing bending machines adjust the die by moving it through a threaded connection, which can easily cause deviations in the movement distance at both ends, affecting the use of the bending machine.

A sliding groove 804 is provided on the right side of the right limiting plate 801 to cooperate with the control mechanism 10.

[0028] The above solution is adopted: by setting the fixing mechanism 8, the positioning block 5 can be fixed, making it convenient for users to use the positioning block 5.

[0029] refer to Figure 3 and Figure 4 The control mechanism 10 includes a rotating plate 1001. A slide rod 1002 that works with the slide groove 804 is fixedly connected to the side of the rotating plate 1001 near the slide groove 804. A torsion bar 1003 is fixedly connected to the side of the rotating plate 1001 away from the limiting plate 801. The side of the torsion bar 1003 away from the rotating plate 1001 passes through the positioning block 5 and extends to the outside of the positioning block 5.

[0030] By adopting the above scheme, the control mechanism 10 can control the fixed mechanism 8, making it convenient for users to use the fixed mechanism 8.

[0031] refer to Figure 3 The side of the limiting block 4 that is close to the inner wall of the limiting groove 6 is in contact with the inner wall of the limiting groove 6. There are several fixing grooves 9, which are evenly distributed on the top of the limiting block 4.

[0032] By adopting the above solution, the positioning block 5 can be limited by setting the limiting block 4 and the limiting groove 6, making it convenient for the user to fix the positioning block 5.

[0033] refer to Figure 3 The bottom of the inner cavity of the movable groove 7 is provided with a first through hole 11 that is used in conjunction with the fixed block 803, and the right side of the inner cavity of the right movable groove 7 is provided with a second through hole 12 that is used in conjunction with the torsion bar 1003.

[0035] refer to Figure 3 and Figure 4 The side of the limiting plate 801 near the inner wall of the movable groove 7 is in contact with the inner wall of the movable groove 7, the top of the spring 802 is fixedly connected to the inner wall of the movable groove 7, and the side of the fixing block 803 near the inner wall of the fixing groove 9 is in contact with the inner wall of the fixing groove 9.

[0036] The above scheme is adopted as follows: by setting the limiting plate 801, the fixing block 803 can be limited; by setting the spring 802, the limiting plate 801 can be reset; and by setting the fixing block 803 and the fixing groove 9, the positioning block 5 can be fixed.

[0037] refer to Figure 3 and Figure 4 The side of the rotating plate 1001 away from the limiting plate 801 is rotatably connected to the inner wall of the movable groove 7 via a rotating shaft. The side of the slide rod 1002 near the inner wall of the slide groove 804 contacts the inner wall of the slide groove 804. The side of the torsion rod 1003 near the inner wall of the second through hole 12 contacts the inner wall of the second through hole 12.

[0038] The above scheme is adopted as follows: by setting the rotating plate 1001, the sliding rod 1002 can be driven to rotate; by setting the sliding rod 1002, the limiting plate 801 can be driven to compress the spring 802; by setting the torsion bar 1003, the rotating plate 1001 can be driven to rotate.

[0039] The working principle of this utility model:

[0040] In use, the user rotates the torsion bar 1003, which drives the rotating plate 1001 to rotate. The rotating plate 1001, through the slide bar 1002, drives the limiting plate 801 to compress the spring 802, and drives the fixing block 803 into the inner cavity of the movable groove 7. The user pushes the positioning block 5, so that the positioning block 5 drives the mold 3 to move to the appropriate position. Then, the user releases the torsion bar 1003. The force released after the spring 802 is compressed pushes the limiting plate 801 to move in the opposite direction, and drives the fixing block 803 to insert into the inner cavity of the fixing groove 9. At the same time, the limiting plate 801, through the slide bar 1002, drives the rotating plate 1001 to rotate in the opposite direction and reset, thus completing the use.

[0041] In summary, this sheet metal bending forming device, through the coordinated use of the fixing mechanism 8, the fixing groove 9, and the control mechanism 10, rotates the torsion bar, which drives the rotating plate 1001 to rotate. The rotating plate 1001, through the sliding rod 1002, drives the limiting plate 801 to compress the spring 802, and drives the fixing block 803 into the inner cavity of the movable groove 7. This solves the problem that in some existing bending machines, when adjusting the die, most of them move the die through a threaded connection, which easily causes deviations in the movement distance at both ends, affecting the use of the bending machine.
