DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figures 1 to 4 As shown, a high-precision stamping and bending die for inserts of the utility model comprises a lower die 1 and an upper die 2, and also comprises a clamping assembly; the clamping assembly comprises a fixing plate 3, the fixing plate 3 is provided with a through hole 1 4, a through hole 2 5 and a through hole 3 6 connected to each other, and also comprises a moving shaft 7 passing through the through hole 1 4, one end of the moving shaft 7 is fixed with one end of an extension rod 8, and the other end of the extension rod 8 is fixed with a clamp, and the purpose of setting the extension rod 8 is to increase the distance between the clamp and the fixing plate 3, so that the space between the lower die 1 and the upper die 2 is larger;

[0025] It also includes a driving mechanism for moving the moving shaft 7 along the through hole 1 4, the through hole 2 5 and the through hole 3 6;

[0026] It also includes a conveyor belt 9 for conveying the parts to be stamped, baffles 10 are fixed on both sides of the conveyor belt 9, and a positioning plate 11 is fixed on one end of the baffle 10 close to the lower mold 1;

[0027] Furthermore, the through hole 2 5 is horizontal, the through hole 1 4 and the through hole 3 6 are vertical, and the through hole 1 4 and the through hole 3 6 are respectively connected to the two ends of the through hole 2 5;

[0028] In this embodiment, the position of the lower mold 1 is fixed, and the upper mold 2 is driven by an external power device to reciprocate up and down. When in use, the part to be stamped is placed on the lower mold 1 through the clamping assembly, and then the external power device is operated to make the upper mold 2 cooperate with the lower mold 1 to complete the stamping;

[0029] The driving mechanism is operated to make the moving shaft 7 move along the through hole 1 4, the through hole 2 5 and the through hole 3 6, thereby driving the extension rod 8 connected to the moving shaft 7, the fixture and the part to be stamped to move along the through hole 1 4, the through hole 2 5 and the through hole 3 6. The through hole 2 5 is horizontal, and the through hole 1 4 and the through hole 3 6 are both vertical. Therefore, when moving along the through hole 1 4 and the through hole 3 6, the part to be stamped moves in the vertical direction, and when moving along the through hole 2 5, the part to be stamped moves in the horizontal direction;

[0030] When in use, the following process is carried out: the parts to be stamped are conveyed by the conveyor belt 9. The baffle 10 and the positioning plate 11 are provided to prevent the parts from being separated from the conveyor belt 9. When the parts to be stamped reach the positioning plate 11, the operating fixture clamps the parts to be stamped, and then the driving mechanism is operated to move the movable shaft 7 along the through hole 1 4, the through hole 2 5 and the through hole 3 6. When moving along the through hole 1 4, the parts to be stamped are moved vertically upward to separate from the conveyor belt 9. When moving along the through hole 2 5, the parts to be stamped are moved to the top of the lower mold 1. When moving along the through hole 3 6, the parts to be stamped are moved onto the lower mold 1. Then the operating fixture releases the parts to be stamped, and then the power device is operated to perform stamping.

[0031] Furthermore, the driving mechanism includes a rotating shaft 12 rotatably connected to the fixed plate 3, a driving rod 13 is fixed to one end of the rotating shaft 12, and a motor 14 is fixed to the other end of the rotating shaft 12;

[0032] The driving rod 13 is provided with a long hole, and the moving shaft 7 passes through the long hole;

[0033] Furthermore, the rotating shaft 12 is located in the middle and lower part of the second through hole 5;

[0034] In this embodiment, the through hole control motor 14 is used to rotate the driving rod 13 around the axis of the rotating shaft 12. Since the rotating shaft 12 is located in the middle and lower part of the through hole 2 5, the driving rod 13 can generate thrust on the moving shaft 7 when rotating, so that it moves along the through hole 1 4, the through hole 2 5 and the through hole 3 6. In order to adapt to the change in the distance between the moving shaft 7 and the rotating shaft 12, the moving shaft 7 moves along the long hole.

[0035] Furthermore, the clamp includes a door-shaped plate 15 fixed to the other end of the extension rod 8, and cylinders 16 are fixed to both ends of the door-shaped plate 15, and the output end of the cylinder 16 is a clamping plate 17;

[0036] In this embodiment, two cylinders 16 are symmetrically arranged. The cylinders 16 are arranged horizontally. The clamping plate 17 is controlled to move by controlling the cylinders 16, so as to achieve clamping and releasing of the parts to be stamped.

[0037] Furthermore, the fixed plate 3 is fixed with a track 18, the track 18 is slidably connected to a slider 19, the slider 19 is fixedly connected to the track 20, and the track 20 is slidably connected to the slider 21;

[0038] The movable shaft 7 passes through the second slider 21 and is fixedly connected to the second slider 21;

[0039] In this embodiment, since slider 21 can only move relative to track 1 18 or track 20 and will not rotate, and the moving shaft 7 passes through slider 21 and is fixedly connected to slider 21, the moving shaft 7 will not rotate either, thereby preventing the fixture from rotating.

[0040] Furthermore, the movable shaft 7 is fixed with a bearing 1, and the outer ring of the bearing 1 is in contact with the inner wall of the through hole 1 4;

[0041] In this embodiment, by providing a bearing 1, the wear on the movable shaft 7 can be reduced.

[0042] Furthermore, the movable shaft 7 is fixed with a second shaft bearing, and the outer ring of the second bearing is in contact with the inner wall of the long hole;

[0043] In this embodiment, the wear on the movable shaft 7 can be reduced by providing the second bearing.

[0044] The utility model discloses a high-precision stamping and bending die for inserts. When in use, the following process is performed: the parts to be stamped are conveyed by the conveyor belt 9. The baffle plate 10 and the positioning plate 11 are provided to prevent the parts from being separated from the conveyor belt 9. When the parts to be stamped reach the positioning plate 11, the cylinder 16 is operated to make the clamp 17 clamp the parts to be stamped. Then, the motor 14 of the driving mechanism is operated to rotate the rotating shaft 12 and the driving rod 13. The moving shaft 7 moves along the through hole 1 4, the through hole 2 5 and the through hole 3 6. When moving along the through hole 1 4, the parts to be stamped are moved vertically upward to be separated from the conveyor belt 9. When moving along the through hole 2 5, the parts to be stamped are moved to the top of the lower die 1. When moving along the through hole 3 6, the parts to be stamped are moved to the lower die 1. Then, the clamp is operated to release the parts to be stamped, and the motor 14 is reversed to restore the clamp to the initial position. Then, the power device is operated to perform stamping.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
