Description

Technical Field

[0001] The present invention relates to the technical field of alloy wire drawing and bending, and particularly to a drawing and bending forming device for alloy wire. Background Art

[0002] Wire drawing refers to the metal plastic processing process of pulling wire through the die hole of a wire drawing die under the action of a drawing force to produce steel wires or non-ferrous metal wires with small cross-sections; and metal wires with different cross-sectional shapes and sizes of various metals and alloys can be produced by wire drawing.

[0003] Most of the existing technologies adopt a drawing and bending forming device and method for high-strength and high-toughness copper and copper alloy wires disclosed in the publication number CN114535328B. This technology is realized through a drawing and bending die composed of two modules, a convex die and a concave die. Through this die, the drawing deformation process and bending deformation process of the reduction of the wire diameter of copper wire can occur; this technology can greatly improve the elongation rate 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 electrical conductivity, and good flexibility. However, there are still problems in the use process due to structural limitations in the above technology:

[0004] Before the above technology performs drawing and bending operations on the wire, the convex die is driven to move horizontally and vertically in sequence to pre-bend the wire located between the convex die and the concave die, so that the wire is not easily broken during the drawing and bending operations. However, due to the freedom of horizontal and vertical movement of the convex die in the above technology and the absence of corresponding locking components, when the wire is performing drawing and bending operations, the convex die is extremely easy to shift under the pulling of the wire, and then the dislocation occurs between the convex die and the concave die, seriously affecting the quality of the wire after the drawing and bending operations.

Detailed implementation manner

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

The wire winding equipment 6 is fixedly connected to the frame 1 at the upper left of the drawing die 2. Before the drawing and bending operation, the wire body 33 is wound and limited on the reel of the wire winding equipment 6. A driving motor is arranged at the wire winding equipment 6, and the reel is rotated by the driving motor, and the wire body 33 is drawn from the first mounting plate 8 to the wire winding equipment 6. The conveying roller 7 is rotatably installed at the upper left of the first auxiliary roller group 4 on the frame 1;

[0047] It should be particularly noted that as shown in the attached Figure 16As shown, the dotted curve located at the drawing die hole 3 is the curved path of the drawing die hole 3. By respectively arranging the first auxiliary roller group 4 and the second auxiliary roller group 5 at the inlet and outlet of the drawing die hole 3, and under the limiting and auxiliary conveying of the first auxiliary roller group 4 and the second auxiliary roller group 5, the drawing die hole 3 and the wire body 33 located in the middle line of the drawing die hole 3 are kept on the same curved path, thereby ensuring the quality of the wire body 33 after drawing and bending operations.

The pre-deformation mechanism is arranged at the left end of the frame 1, and the pre-deformation mechanism is used to first perform forging deformation on the wire body 33 in the front-back direction, and then perform forging deformation on the wire body 33 in the up-down direction, so as to perform two grain refinements on the wire body 33 and improve the toughness and plasticity of the wire body 33, making the wire body 33 not easy to break during the drawing and bending operations. After the wire body 33 completes two forging deformations, the diameter of the wire body 33 is slightly larger than the diameter of the drawing die hole 3, and as shown in the appendix Figure 16 As shown, the wire body 33 is erected on the conveying roller 7, and then passes through the first auxiliary roller group 4, and the wire body 33 passes out from the outlet of the drawing die hole 3, so that the diameter of the wire body 33 becomes smaller, the extension length increases, and it is bent; The auxiliary limiting mechanism is arranged at the pre-deformation mechanism, and the auxiliary limiting mechanism is used to assist in limiting the wire body 33 during the two forging deformation processes, so as to improve the stability of the wire body 33 during the two forging deformation processes;

[0049] The pre-deformation mechanism includes a first mounting plate 8, a first fixed cylinder 9 and a transverse chute 10. The first mounting plate 8 is fixedly connected to the left end of the frame 1. As shown in the appendix Figure 12 As 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 chutes 10 are symmetrically opened at the front and rear ends of the first mounting plate 8;

[0050] Preferably, the pre-deformation mechanism further includes a first connecting rod 11, a transverse hydraulic cylinder 12 and a first moving cylinder 13.

By starting the two transverse hydraulic cylinders 12, the two first moving cylinders 13 repeatedly hammer the front and rear ends of the wire body 33, so that the wire body 33 located on the first mounting plate 8 is from the appendixFigure 12 The deformation shown is attached Figure 13 as shown

[0051] The pre-deformation mechanism further includes a second mounting plate 14, vertical sliding grooves 15 and second connecting rods 16. The second mounting plate 14 is fixedly installed on the frame 1 to the right of the first mounting plate 8. Two groups of vertical sliding grooves 15 are respectively penetrated and opened at the front and rear ends of the second mounting plate 14, and two second connecting rods 16 are respectively slidably sleeved in the two groups of vertical sliding grooves 15;

[0052] Preferably, the pre-deformation mechanism further includes vertical hydraulic cylinders 17, second moving cylinders 18 and second fixed cylinders 19. As attached Figure 11 shown, two groups of vertical hydraulic cylinders 17 are respectively fixedly installed in the two groups of vertical sliding grooves 15, and the output ends of one group of vertical hydraulic cylinders 17 are respectively fixedly connected to the front and rear ends of a second connecting rod 16. Two second moving cylinders 18 are respectively fixedly connected to the middle ends of the two second connecting rods 16, and the two second moving cylinders 18 are symmetrically arranged with respect to the upper and lower ends of the second mounting plate 14. 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 that is located on the second mounting plate 14 and has completed the forging deformation in the front and rear directions, and by starting the two vertical hydraulic cylinders 17, the two second moving cylinders 18 reciprocally 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 deformed from the attached Figure 14 shown to the attached Figure 15 shown

[0053] It should be specifically noted that during the two forging deformations of the wire body 33, first let a section of the wire body 33 complete the forging deformation in the front and rear directions at the first mounting plate 8, and reset the auxiliary limiting mechanism, and then use the wire winding device 6 to draw the wire body 33 that has completed the forging deformation in the front and rear directions to the second mounting plate 14. At this time, the unprocessed wire body 33 enters the first mounting plate 8 and is forged in the front and rear directions until the wire body 33 that has completed the forging deformation in the front and rear directions is located in the second mounting plate 14, and is forged in the up and down directions, and the auxiliary limiting mechanism is reset, and then the wire body 33 that has completed the two forging deformations is drawn to the drawing die hole 3, and then the wire body 33 that has completed the forging deformation in the front and rear directions enters the second mounting plate 14, and the wire body 33 is forged in the up and down directions;

[0054] The auxiliary limiting mechanism includes an inclined chute member 20, an inclined blocking plate 21 and an adjusting block 22. As attached Figure 3 and attached Figure 9As 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.

[0055] 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. Figure 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.

[0056] 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.

[0057] In particular, the attached Figure 12As shown, 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 rod 28, and move a group 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 pull the adjusting block 22 out of the inclined chute member 20 in the front end direction and push the adjusting block 22 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 into the inclined chute member 20. Finally, screw in the locking bolt 30 to continue connecting the adjusting block 22 with the connecting slide rod 28 and complete the preparatory work for the forging deformation in the front and rear directions. 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 moving cylinder 13 and the first fixed cylinder 9 contracts towards the center of the wire body 33. At this time, through the elastic force of the auxiliary spring 32 in the squeezed state, a group of auxiliary limiting cylinders 31 are moved to abut against the outer arc end of the wire body 33 to assist in limiting the wire body 33 that has completed the forging deformation in the front and rear directions; Figure 12 Pull out the inclined chute member 20 in the front end direction and push the adjusting block 22 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 into the inclined chute member 20. Finally, screw in the locking bolt 30 to continue connecting the adjusting block 22 with the connecting slide rod 28 and complete the preparatory work for the forging deformation in the front and rear directions. 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 moving cylinder 13 and the first fixed cylinder 9 contracts towards the center of the wire body 33. At this time, through the elastic force of the auxiliary spring 32 in the squeezed state, a group of auxiliary limiting cylinders 31 are moved to abut against the outer arc end of the wire body 33 to assist in limiting the wire body 33 that has completed the forging deformation in the front and rear directions;

[0058] And as attached Figure 14 As shown, when the wire body 33 that has completed the forging deformation in the front and rear directions is located in the second mounting plate 14, reset the auxiliary limiting mechanism at the second mounting plate 14 and repeat the above operations 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 adjusting block 22 moves away from the wire body 33 and squeezes the auxiliary spring 32 to complete the preparatory work for the forging deformation in the up and down directions. When the wire body 33 completes the forging deformation in the up and down directions, the outer arc end of the wire body 33 located between the second moving cylinder 18 and the second fixed cylinder 19 contracts towards the center of the wire body 33. At this time, through the elastic force of the auxiliary spring 32 in the squeezed state, a group of auxiliary limiting cylinders 31 are moved to abut against the outer arc end of the wire body 33 to assist in limiting the wire body 33 that has completed the forging deformation in the up and down directions;

[0059] As attached Figure 13 And as attached Figure 15 As shown, during the forging deformation of the wire body 33 in the front and rear directions and the up and down directions, vibration forces are generated, and these vibration forces provide a force in the direction away from the wire body 33 to the auxiliary limiting cylinders 31, causing the adjusting block 22 to have a tendency to move in the direction away from the wire body 33. And as attached Figure 6As described above, at this time, the upper end of the rotation limiting plate 24 abuts against the lower end of the inclined blocking plate 21, so that the inclined blocking plate 21 pushes the rotation limiting plate 24 to rotate towards the lower end of the adjusting block 22. However, since the rotation limiting plate 24 abuts against the blocking long block 26 at one end of the mounting shaft 23, the rotation limiting plate 24 is prevented from rotating towards the lower end of the adjusting block 22, so that the adjusting block 22 cannot move away from the wire body 33, thereby maintaining the auxiliary limiting of the wire body 33 by the auxiliary limiting cylinder 31.

[0060] The functional principle of the present invention can be described by the following operation method:

[0061] First, one end of the wire body 33 is sequentially passed through the middle ends of the first mounting plate 8 and the second mounting plate 14, and one end of the wire body 33 is placed on the conveying roller 7. Then, one end of the wire body 33 is sequentially passed through the first auxiliary roller group 4, the drawing die hole 3 and the second auxiliary roller group 5, and finally one end of the wire body 33 is wound and limited on the winding device 6.

[0062] After that, the winding device 6 is started. As shown in the attachment Figure 2 Let the drum in the winding device 6 rotate counterclockwise to draw the wire body 33 from the first mounting plate 8 to the winding device 6, and start the two horizontal hydraulic cylinders 12 to make the two first moving cylinders 13 move relatively in the front-rear direction and hammer the front and rear ends of the wire body 33. At the same time, the wire body 33 is limited in the up-down direction by the two first fixed cylinders 9. As shown in the attachment Figure 13 To make the wire body 33 complete the forging deformation in the front-rear 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.

[0063] At the same time, the outer arc end of the wire body 33 between the first moving cylinder 13 and the first fixed cylinder 9 contracts towards 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. Under the elastic force of the auxiliary spring 32 in the extrusion state, the adjusting block 22 drives the auxiliary limiting cylinder 31 to move towards the outer arc end of the wire body 33 together through the connecting slide rod 28. As shown in the attachment Figure 10 When the lower end of the rotation limiting plate 24 abuts against the upper end of the inclined blocking plate 21, the adjusting block 22 continues to move towards the outer arc end of the wire body 33, so that the inclined blocking plate 21 pushes the rotation limiting plate 24 to rotate towards the upper end of the adjusting block 22, so that the adjusting block 22 moves between the two lower inclined blocking plates 21. And the rotation limiting plate 24 returns to the initial state under the elastic force of the reset torsion spring 25, so as to facilitate the rotation limiting plate 24 to pass through another inclined blocking plate 21 next time, until the four auxiliary limiting cylinders 31 continue to abut against the outer arc end of the wire body 33 to perform auxiliary limiting on the wire body 33 that has completed the forging deformation in the front-rear direction.

[0064] The wire body 33 continues to move towards the coiling device 6, so that the wire body 33 which has completed the forging deformation in the front-back direction is located at the second mounting plate 14, and two sets of vertical hydraulic cylinders 17 are started. As shown in the Figure 2 attachment, the two second moving cylinders 18 move relatively in the up-down direction and hammer 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 two second fixing cylinders 19. As shown in the Figure 15 attachment, so that the wire body 33 completes the forging deformation in the up-down direction. At this time, the cross-section of the wire body 33 is approximately circular arc;

[0065] Meanwhile, the outer arc end of the wire body 33 located between the second moving cylinder 18 and the second fixing cylinder 19 shrinks towards the center of the wire body 33, and a set of adjusting blocks 22 of the second mounting plate 14 repeat the movement of a set of adjusting blocks 22 of the first mounting plate 8, so that a set of adjusting blocks 22 move towards the outer arc end of the wire body 33 until the four auxiliary limiting cylinders 31 continue to abut against the outer arc end of the wire body 33, and perform auxiliary limiting on the wire body 33 which has completed the forging deformation in the up-down direction;

[0066] The wire body 33 continues to move towards the coiling device 6, so that the wire body 33 which has successively completed the forging deformation in the front-back direction and the forging deformation in the up-down direction moves to the entrance of the drawing die hole 3, and under the pulling of the coiling device 6, the wire body 33 passes through from the exit of the drawing die hole 3 and performs the drawing and bending operation. Finally, the wire body 33 which has completed the drawing and bending operation is wound on the reel for collection.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitution or change, and should be covered by the protection scope of the present invention.
