Embodiment 1

[0032] Such as Figure 1 to Figure 5 As shown, a wire drawing device used in a multi-pass corner wire drawing forming method includes a wire winding device 1 arranged in a straight line, a mold fixing seat 2 and a tailstock 3 .

[0033] The wire winding device 1 includes a driving motor 1-1, a gearbox 1-2, a turntable 1-3 and a winding rod 1-4, the driving motor 1-1 is connected to the gearbox 1-2, and the output shaft of the gearbox is connected to The rotating disk 1-3 is fixed on the rotating disk 1-3 around the screw mandrel 1-4. For the convenience of operation, three winding screw mandrels 1-4 are installed on the rotating disk 1-3, and the three winding screw mandrels 1-4 are located on the same circle with the center of the rotating disk 1-3 as the center.

[0034] A clamp mechanism 4 is provided at the top of the mold holder 2 , and the wire drawing die 5 is clamped and fixed by the clamp mechanism 4 . The wire drawing die 5 includes a left fixed plate 5-1, a right ...

Embodiment 2

[0048] see Figure 6 The difference between this embodiment and Embodiment 1 is that the elongated blind grooves 5-5 correspondingly opened on the left and right fixing plates 5-1, 5-2 in the wire drawing device are vertically arranged, and the first forming rod The two ends of 5-3 are movably fitted in the elongated blind groove 5-5, the two ends of the second forming rod 5-4 are fitted in the fixed blind groove 5-6, and the second forming rod 5-4 is located in the first forming One side of the rod 5-3, and the second forming rod 5-4 and the first forming rod 5-3 are parallel to each other.

[0049] In the corresponding wire drawing forming method, the vertical distance between the first forming rod and the second forming rod is adjusted by adjusting the position of the first forming rod in the elongated blind groove.

Abstract

The invention discloses a multiple-pass corner wire drawing forming method and a wire drawing device. The wire drawing device comprises a wire drawing die and a wire winding device, wherein the wire drawing die is provided with a first forming rod and a second forming rod, the first forming rod can be horizontally or vertically moved, and the second forming rod is fixed; under the matching action of two forming rods, the different wire drawing angles and corner radiuses can be formed, and the different times of drawing can be performed. The wire drawing device has the advantages that the different materials can be performed with wire drawing and forming, and the mechanical property of metal wires can reach different optimum effect, and different grain fining effect.

Description

technical field [0001] The invention belongs to the technical field of wire drawing, and in particular relates to a multi-pass corner wire drawing forming method and a wire drawing device. Background technique [0002] As an emerging plastic deformation method, severe plastic deformation can introduce a large amount of strain in the deformation process (traditional plastic deformation is difficult to achieve a true strain with a strain value greater than 1), thereby effectively refining (submicron or nanometer level) ) metals, through the control of the microstructure during the deformation process, nanomaterials with high strength and large plasticity can be obtained at the same time. [0003] However, the wire drawing forming method and device in the prior art have complex structures and processes, and the applicable material is single, so the forming effect is not good. For example, the Chinese invention patent with the authorized notification number CN103706666A disclos...
