The technology is realized by a drawing and bending die composed of two modules, a convex die and a concave die. The drawing deformation process and the bending deformation process of reducing the diameter of the copper wire can occur through the die; the technology can greatly improve the elongation of copper and copper alloy wires, improve the drawability of copper and copper alloy wires, and make copper and copper alloy wires have excellent comprehensive properties such as high strength, high conductivity and good flexibility. However, the above technology still has problems in use due to structural limitations: Before the wire is drawn and bent, the above-mentioned technology drives the male die to move laterally and vertically in sequence, so that the wire in the male die and the female die is pre-bent, so that the wire is not easily broken during the drawing and bending operation. However, since the male die of the above-mentioned technology has the freedom to move laterally and vertically, and there is no corresponding locking component, when the wire is drawn and bent, the male die is easily offset by the pull of the wire, which causes misalignment between the male die and the female die, seriously affecting the quality of the wire after the drawing and bending operation.

The first mounting plate 8 is fixedly connected to the left end of the frame 1. Fig.12As shown, two first fixed cylinders 9 are symmetrically fixedly connected to the upper and lower ends of the first mounting plate 8 to limit the upper and lower ends of the wire body 33 located on the first mounting plate 8, and two transverse slide grooves 10 are symmetrically opened at the front and rear ends of the first mounting plate 8; Preferably, the pre-deformation mechanism also includes a first connecting rod 11, a transverse hydraulic cylinder 12 and a first movable cylinder 13, the two first connecting rods 11 are respectively slidably sleeved in the two transverse slide grooves 10, the two transverse hydraulic cylinders 12 are respectively fixedly installed in the two transverse slide grooves 10, and the output ends of the two transverse hydraulic cylinders 12 are respectively fixedly connected to the two first connecting rods 11, the two first movable cylinders 13 are respectively fixedly connected to the ends of the two first connecting rods 11 away from the transverse slide grooves 10, and the two first movable cylinders 13 are symmetrically arranged at the front and rear ends of the first mounting plate 8.

Two sets of vertical slide grooves 15 are respectively opened at the front and rear ends of the second mounting plate 14. The two second connecting rods 16 are respectively slidably sleeved in the two sets of vertical slide grooves 15. Preferably, the pre-deformation mechanism further comprises a vertical hydraulic cylinder 17, a second movable cylinder 18 and a second fixed cylinder 19, as shown in the attached Fig.11 As shown, two groups of vertical hydraulic cylinders 17 are respectively fixedly installed in two groups of vertical slide grooves 15, and the output end of one group of vertical hydraulic cylinders 17 is respectively fixedly connected to the front and rear ends of a second connecting rod 16, and the two second movable cylinders 18 are respectively fixedly connected to the middle ends of the two second connecting rods 16, and the two second movable cylinders 18 are symmetrically arranged at the upper and lower ends of the second mounting plate 14, and the two second fixed cylinders 19 are symmetrically fixedly connected to the front and rear ends of the second mounting plate 14 to limit the front and rear ends of the wire body 33 located on the second mounting plate 14 and completing the forging deformation in the front and rear directions, and by starting the two vertical hydraulic cylinders 17, the two second movable cylinders 18 reciprocate to hammer the upper and lower ends of the wire body 33, so that the wire body 33 located on the second mounting plate 14 is moved from the attached Fig.14 The deformation shown is attached Fig.15 shown.

[0019] It is particularly noted that, during the process of performing two forging deformations on the wire body 33, a section of the wire body 33 is first allowed to complete the forging deformation in the front-to-back direction at the first mounting plate 8, and the auxiliary limiting mechanism is reset, and then the wire body 33 that has completed the forging deformation in the front-to-back direction is drawn to the second mounting plate 14 through the winding device 6. At this time, the unprocessed wire body 33 enters the first mounting plate 8 and is forged in the front-to-back direction until the wire body 33 that has completed the forging in the front-to-back direction is located in the second mounting plate 14, and is forged in the up-and-down direction, and the auxiliary limiting mechanism is reset, and then the wire body 33 that has completed the forging deformation twice is drawn into the drawing die hole 3, and the wire body 33 that has subsequently completed the forging deformation in the front-to-back direction enters the second mounting plate 14, and is forged in the up-and-down direction. The auxiliary limiting mechanism includes an inclined slide member 20, an inclined blocking plate 21 and an adjusting block 22. Figure 3 and attached Fig. 9 As shown, two groups of inclined slide members 20 are respectively fixedly connected to the middle ends of the first mounting plate 8 and the second mounting plate 14, and one group of inclined slide members 20 is composed of four inclined slide members 20 distributed equidistantly around the circumference, a group of inclined baffles 21 are integrally formed at the front and rear inner walls of an inclined slide member 20, and one group of inclined baffles 21 is composed of a plurality of inclined baffles 21 distributed equidistantly in a straight line, and the inclined baffles 21 are all triangular plates, and an adjustment block 22 is movably mounted in an inclined slide member 20.

[0020] Preferably, the auxiliary limiting mechanism also includes a mounting shaft 23, a rotation limiting plate 24, a reset torsion spring 25 and a blocking long block 26. The two mounting shafts 23 are rotatably mounted at the front and rear ends of an adjusting block 22. The two rotation limiting plates 24 are respectively fixedly mounted on the two mounting shafts 23. The two rotation limiting plates 24 are both triangular plates. A reset torsion spring 25 is fixedly mounted at the connection between a mounting shaft 23 and a rotation limiting plate 24. Fig.10 As shown, when the adjusting block 22 moves toward the outer arc end of the wire body 33, the lower end of the rotating limit plate 24 is abutted against the upper end of the inclined baffle plate 21, so that the inclined baffle plate 21 pushes the rotating limit plate 24 to rotate toward the upper end of the adjusting block 22 to allow the adjusting block 22 to pass through the inclined baffle plate 21, and when the adjusting block 22 is located between the two inclined baffle plates 21, the rotating limit plate 24 is restored to its initial state through the elastic force of the reset torsion spring 25, and a blocking long block 26 is fixedly connected to an adjusting block 22 below a rotating limit plate 24, and a blocking long block 26 and a rotating limit plate 24 are movably abutted against each other at one end of the mounting shaft 23.

[0021] The auxiliary limiting mechanism also includes a guide slot 27, a connecting slide rod 28, a threaded hole 29 and a locking bolt 30, wherein a guide slot 27 is provided through the bottom of an inclined slot member 20, one end of a connecting slide rod 28 is slidably sleeved in a guide slot 27, and the connecting slide rod 28 is guided by the guide slot 27 to allow linear movement of the connecting slide rod 28, a group of threaded holes 29 are provided at one end of an adjusting block 22 close to the guide slot 27 and a connecting slide rod 28 is located at one end of the guide slot 27, and the adjusting block 22 is connected to the connecting slide rod 28 through the locking bolt 30; an auxiliary limiting cylinder 31 and an auxiliary spring 32, an auxiliary limiting cylinder 31 is fixedly connected to one end of a connecting slide rod 28 away from the guide slot 27, and both ends of an auxiliary spring 32 are welded between an inclined slot member 20 and an adjusting block 22.

[0022] In particular, the attached Fig.12 As shown in the figure, when the unprocessed wire body 33 is located in the first mounting plate 8, when resetting the auxiliary limiting mechanism at the first mounting plate 8, first unscrew the locking bolt 30 to separate the adjusting block 22 from the connecting slide bar 28, and move a set of auxiliary limiting cylinders 31 to abut against the outer arc end of the unprocessed wire body 33 to limit the wire body 33, and then move the adjusting block 22 to the attached Fig.12 The inclined slide member 20 is pulled out in the front end direction, and the adjusting block 22 is pushed to move away from the wire body 33. At this time, the adjusting block 22 squeezes the auxiliary spring 32 until the adjusting block 22 is aligned with the connecting slide rod 28 and the adjusting block 22 is placed in the inclined slide member 20, and finally the locking bolt 30 is screwed in to allow the adjusting block 22 to continue to be connected with the connecting slide rod 28, and the preparation work for the forging deformation in the front and rear directions is completed. When the wire body 33 completes the forging deformation in the front and rear directions, the outer arc end of the wire body 33 located between the first movable cylinder 13 and the first fixed cylinder 9 shrinks toward the center of the wire body 33. At this time, through the elastic force of the auxiliary spring 32 in the extrusion state, a group of auxiliary limiting cylinders 31 are moved to counteract the outer arc end of the wire body 33, so as to assist in limiting the wire body 33 that has completed the forging deformation in the front and rear directions; And as attached Fig.14As shown, when the wire body 33 that has completed the forging deformation in the front-to-back direction is located in the second mounting plate 14, the auxiliary limiting mechanism at the second mounting plate 14 is reset, and the above operation is repeated, so that a group of auxiliary limiting cylinders 31 abut against the outer arc end of the wire body 33 to limit the wire body 33, and at the same time, the adjustment block 22 moves away from the wire body 33 and squeezes the auxiliary spring 32 to complete the preparation work for the forging deformation in the up-down direction. When the wire body 33 completes the forging deformation in the up-down direction, the outer arc end of the wire body 33 located between the second movable cylinder 18 and the second fixed cylinder 19 shrinks toward the center of the wire body 33. At this time, through the elastic force of the auxiliary spring 32 in the extrusion state, a group of auxiliary limiting cylinders 31 are moved to abut against the outer arc end of the wire body 33 to auxiliary limit the wire body 33 that has completed the forging deformation in the up-down direction. As attached Fig.13 and attached Fig.15 As shown in FIG. 1 , during the forging deformation of the wire body 33 in the front-to-back direction and the up-to-down direction, a vibration force is generated, and the vibration force provides a force to the auxiliary limiting cylinder 31 in the direction away from the wire body 33, so that the adjustment block 22 has a tendency to move away from the wire body 33. Figure 6 As described above, at this time, the upper end of the rotation limit plate 24 is abutted against the lower end of the inclined baffle plate 21, so that the inclined baffle plate 21 pushes the rotation limit plate 24 to rotate toward the lower end of the adjusting block 22. However, since the rotation limit plate 24 is located at one end of the mounting shaft 23 and abuts against the blocking long block 26 to prevent the rotation limit plate 24 from rotating toward the lower end of the adjusting block 22, the adjusting block 22 cannot move away from the wire body 33, thereby maintaining the auxiliary limiting effect of the auxiliary limiting cylinder 31 on the wire body 33.

[0023] The present invention can be explained by the following operation mode: First, one end of the wire body 33 is passed through the middle end of the first mounting plate 8 and the middle end of the second mounting plate 14 in sequence, and one end of the wire body 33 is mounted on the conveying roller 7, and then one end of the wire body 33 is passed through the first auxiliary roller group 4, the drawing die hole 3, and the second auxiliary roller group 5 in sequence, and finally one end of the wire body 33 is wound and limited on the winding device 6; Then start the winding device 6, as shown in the attached Figure 2 As shown, the reel in the winding device 6 is rotated counterclockwise to draw the wire body 33 from the first mounting plate 8 to the winding device 6, and the two transverse hydraulic cylinders 12 are started to make the two first movable cylinders 13 move relative to each other in the front and rear directions and beat the front and rear ends of the wire body 33. At the same time, the wire body 33 is limited in the upper and lower directions by the two first fixed cylinders 9, as shown in the attached figure. Fig.13 As shown, the wire body 33 is forged and deformed in the front-to-back direction. At this time, the cross section of the wire body 33 is an ellipse with a short horizontal axis and a long vertical axis. At the same time, the outer arc end of the wire body 33 located between the first movable cylinder 13 and the first fixed cylinder 9 shrinks toward the center of the wire body 33, so that the auxiliary limiting cylinder 31 is separated from the outer arc end of the wire body 33, and under the elastic force of the auxiliary spring 32 in the extrusion state, the adjustment block 22 drives the auxiliary limiting cylinder 31 to move toward the outer arc end of the wire body 33 through the connecting slide rod 28, as shown in the attached figure. Fig.10 As shown, when the lower end of the rotation limit plate 24 abuts against the upper end of the inclined baffle plate 21, the adjustment block 22 continues to move toward the outer arc end of the wire body 33, so that the inclined baffle plate 21 pushes the rotation limit plate 24 to rotate toward the upper end of the adjustment block 22, so that the adjustment block 22 moves between the two lower inclined baffle plates 21, and the rotation limit plate 24 is restored to its initial state under the elastic force of the reset torsion spring 25, so that the rotation limit plate 24 passes through another inclined baffle plate 21 next time, until the four auxiliary limit cylinders 31 continue to abut against the outer arc end of the wire body 33, and the wire body 33 that has completed the forging deformation in the front and rear directions is auxiliary limited; The wire body 33 continues to move toward the winding device 6, so that the wire body 33 that has completed the forging deformation in the front and rear directions is located at the second mounting plate 14, and the two sets of vertical hydraulic cylinders 17 are started, as shown in the attached figure. Figure 2 As shown, the two second movable cylinders 18 are relatively moved in the up-down direction and hit the upper and lower ends of the wire body 33. At the same time, the wire body 33 is limited in the front-back direction by the two second fixed cylinders 19.
