[0043] The metal table 2 is provided with an arc-shaped motion groove 31, the axis of which coincides with the axis of the metal table 2, so that the motion frame 3 moves in an arc-shaped circle;

[0044] There are two groups of moving frames 3 , and both groups of moving frames 3 are clamped in the arc-shaped moving groove 31 , and the moving frames 3 can move in the arc-shaped moving groove 31 .

[0045] The motion frame 3 includes a motion frame plate 32 clamped in the arc motion groove 31, and a rotating table 37 is provided at the lower end of the motion frame plate 32. The rotating table 37 is located at the lower end of the metal table 2, and its lower end is fixed to the driving motor. The upper end of the motion frame plate 32 is provided with a plurality of threaded holes fixed to the rotating table 37 and abutting against the metal table 2, so as to limit or move the motion frame plate 32 for easy adjustment.

[0046] A metal fitting 35 for pressing a metal part is clamped on the moving frame plate 32 . The metal fitting 35 is used to press the metal part and press the metal part into a bent shape.

[0047] A clamping shaft 33 is provided at the upper end of the moving frame plate 32, and a clamping groove 36 is provided at the lower end of the metal fitting 35. The clamping shaft 33 and the clamping groove 36 are matched to limit the metal fitting 35.

[0048] An extrusion rod 34 is inserted through the outer side of the moving frame plate 32, and the extrusion rod 34 is rotatably connected to the moving frame plate 32. The extrusion rod 34 has a thread on the outer side, and is inserted into the interior of the metal accessory 35. The two are threadedly connected.

[0057] One group of moving frames 32 is fixed to the metal table top 2, and the position of the moving frames 32 can be adjusted. This group of moving frames 32 is used for fixing, and the other group is used for movement, thereby achieving adjustment of different positions and bending in different states, and having a wider range of applications.

[0058] Embodiment 2:

[0059] On the basis of the first embodiment, the outer sides of the fixing layer 1 41 and the fixing layer 2 42 are both provided with a fixing assembly 5, and the fixing assembly 5 includes a bending frame 51, an arc-shaped metal strip 1 52, an insertion shaft 54 ​​and an arc-shaped metal strip 2 55.

The end of the bending frame 51 is spherical, and a round mouth 1 53 is provided on the protruding side of the arc-shaped metal strip 1 52. The spherical end of the bending frame 51 is clamped in the round mouth 1 53. The insertion shaft 54 ​​is fixed to the concave side of the arc-shaped metal strip 1 52.

A round mouth 2 56 is provided on the end of the arc-shaped metal strip 2 55, and the round mouth 2 56 cooperates with the spherical end of the insertion shaft 54.

[0060] The upper and lower groups of fixing components 5 are symmetrically arranged, and the distance between the two groups of plug shafts 54 is closer than the distance between the two groups of bending frames 51. The arc-shaped metal strip 2 55 is squeezed against the metal part, so that the arc-shaped metal strip 1 52 tilts inward to clamp the metal part. The arc-shaped metal strip 2 55 and the arc-shaped metal strip 1 52 can both be partially rotated to make the arc-shaped metal strip 2 55 fit together, and the end of the arc-shaped metal strip 1 52 is also squeezed against the metal part to achieve limiting.

[0061] The fixed frame 4 is rotated so that one side of the fixed component 5 faces the moving frame 3. When the metal part and the fixed component 5 are extruded, they are extruded with the arc-shaped metal strip 2 55. With the action of pressure and the cooperation of the bending frame 51, the insertion shaft 54 ​​and the round mouth 1 53 and the round mouth 2 56, the arc surface of the arc-shaped metal strip 2 55 is still in contact with the metal part, but the arc-shaped metal strip 1 52 is bent inward, so that the outer end of the arc-shaped metal strip 1 52 also moves, which can extrude the metal part. The metal part with a small diameter can be extruded by the arc-shaped metal strip 2 55. It is suitable for metal parts with a small diameter, and both the arc-shaped metal strip 1 52 and the arc-shaped metal strip 2 55 can be extruded, the contact area is increased, and the deformation of the metal part is reduced.
