Description

Technical Field

[0001] This invention relates to the field of alloy wire drawing technology, and more specifically, to an alloy wire drawing device and its drawing process. Background Technology

[0002] Alloy wire drawing is a plastic processing technology that uses external force to force an alloy billet through a die with a specific aperture, causing the billet to undergo plastic deformation and ultimately produce a fine wire product. It is one of the core technologies for preparing high-precision alloy wires.

[0003] When using the existing wire drawing equipment, the operator first passes the alloy wire through the drawing die, then winds it around the outer wall of the roller, and then installs the drawing die onto the drawing die base; by rotating the roller, the drawing process of the alloy wire can be completed.

[0004] In conventional scenarios, some pulleys have a conical structure. To ensure that the alloy wire can be drawn horizontally, the drawing die base is machined to match the tilt angle of the pulley. However, this method of machining the drawing die base according to the shape of the pulley will significantly increase the production cost of the drawing die base. To address this issue, the staff has made improvements and optimizations to the existing system. The horizontal die base can swing within the drawing device, thereby adjusting the tilt angle of the horizontal die base. This eliminates the need for contour machining and enables horizontal drawing of the alloy wire, effectively avoiding the high cost problem.

[0005] However, the horizontal die holder tilting scheme still has the following problems: some of the pulleys are non-uniform stepped structures, that is, not conventional conical structures. Their diameter decreases at different rates, and the conical cross-section is curved. This special structure means that even if the angle of the horizontal die holder is adjusted, the wire drawing die cannot be matched with the pulley groove position, which leads to the situation where the horizontal die holder tilting method is not applicable.

[0062] Referring to Figure 3 and Figure 4 , the inside of the box body 12 is provided with two capstan assemblies 4, which are used for guiding and winding the alloy wire during the drawing process and providing continuous and stable traction, and the specific structure of the capstan assembly 4 is as follows:

[0063] Referring to Figure 4 and Figure 5 , the two capstan assemblies 4 each comprise a rotating shaft 41 rotatably connected to the inside of the box body 12, the outer side wall of the two rotating shafts 41 is provided with a capstan body 42, the capstan body 42 can be replaced according to the needs, the capstan body 42 is installed on the outer wall of the corresponding rotating shaft 41, the inside of the frame 11 is provided with two capstan drive mechanisms, which can be capstan drive motors, which are not limited here, the output end of the capstan drive motor is connected with the corresponding rotating shaft 41, the capstan drive motor drives the rotating shaft 41 to rotate, thereby driving the corresponding capstan body 42 to rotate, and the rotating directions of the two capstan bodies 42 are consistent when the two capstan assemblies 4 are running, the alloy wire is wound around the capstan body 42, the alloy wire is wound in the capstan groove on the capstan body 42, and the capstan body 42 provides continuous and stable traction to the wound alloy wire through rotation.

[0064] Referring to Figures 4-6 , the inside of the box body 12 is provided with a die holder assembly 5, which is located between the two capstan assemblies 4, the die holder assembly 5 comprises an I-shaped frame 51 and a plurality of wire drawing dies 546, the wire drawing dies 546 are arranged according to the diameter change of the capstan body 42, the wire drawing dies 546 are used for drawing the alloy wire, so that the alloy wire can achieve the purpose of reducing the diameter and setting the diameter.

[0065] Specifically, the alloy wire guided by the guide wire assembly 2 enters the inside of the box body 12, reaches the inside of the box body 12, then passes through one of the selected drawing dies 546, and is reserved with a proper length, then the alloy wire is wound into the tower groove on the top of the outer wall of the first tower body 42 and the second tower body 42 in turn, the alloy wire is wound again through the tower groove below the first tower body 42 after winding through the tower groove of the outer wall of the second tower body 42, then the next drawing die 546 is passed through, and the alloy wire is wound into the tower groove on the top of the outer wall of the first tower body 42 and the second tower body 42 again. In this way, the winding is repeated until the winding of the tower groove on the outer wall of the tower body 42 is completed. After the winding is completed, the alloy wire enters the inside of the winding box 31 through the exit die 32, and then the guide and winding operation is performed by using the winding assembly 3.

[0066] During the winding of the alloy wire, the two tower bodies 42 rotate synchronously, thereby providing a traction force to the alloy wire drawn in the drawing die 546. In addition, in order to avoid equipment wear and hot brittleness of the alloy wire due to overheating during drawing, the drawing oil is sprayed on the surface of the drawing die 546 and the tower body 42, thereby playing a lubricating and cooling role. The box body 12 can simultaneously carry and collect the used drawing oil.

[0067] In the second embodiment, the horizontal die holder is swung in the drawing device, thereby adjusting the inclination angle of the horizontal die holder, and the horizontal drawing of the alloy wire can be realized without profiling processing, which can effectively avoid high cost problems. However, part of the tower is a non-equal ratio stepped structure, that is, it is not a conventional conical structure, and the change range of the diameter is not uniform, and the conical section is in a curved shape. This special structure will cause the drawing die 546 to be unable to adapt to the position of the tower groove of the tower, and the swinging and tilting of the horizontal die holder cannot be used.

[0068] Therefore, the die holder assembly 5 is further improved.

[0069] Referring to Figures 6-11 , the I-shaped frame 51 is connected with a square support rod 52 on one side, the I-shaped frame 51 and the inner wall of the box body 12 are threadedly connected with locking bolts 55, the I-shaped frame 51 is installed on the inner wall of the box body 12 through the locking bolts 55, and the outer side wall of the square support rod 52 is provided with a plurality of module mechanisms 54. The plurality of module mechanisms 54 are placed by the square support rod 52.

[0070] Referring to Figures 6-11 , the specific structure of the module mechanism 54 is as follows:

[0071] Each module mechanism 54 comprises a coupling block 541 and a through slot 542 formed in the side wall of the coupling block 541, the square support rod 52 is arranged in the through slot 542, each wire drawing die 546 is arranged on the top of the corresponding coupling block 541, and each coupling block 541 corresponds to one wire drawing die 546. When the coupling block 541 is sleeved on the outside of the square support rod 52, the plurality of coupling blocks 541 are lowered under the action of gravity, the plurality of coupling blocks 541 are at the same height, in this state, the plurality of wire drawing dies 546 are also arranged in a horizontal arrangement, at this time, the wire drawing die 546 is suitable for a single-diameter drum wheel type tower wheel body 42, and the lengths of the selected different tower wheel bodies 42 are different, so the number of the coupling blocks 541 is also different according to the required splicing.

[0072] Referring to Figures 6-11 , two placing grooves 547 are formed in the top of the coupling block 541, the wire drawing die 546 is arranged in one of the placing grooves 547 on the top of the corresponding coupling block 541, and the side wall of the coupling block 541 and the side wall of the placing groove 547 are provided with a wire slot 545, the wire slot 545 is provided with a chamfer in the inside, when the wire drawing die 546 is arranged on the top of the coupling block 541, the wire drawing die 546 is clamped in the inside of the placing groove 547, when the alloy wire passes through the wire drawing die 546, the alloy wire first passes through the wire slot 545 and the chamfer in the inside of the wire slot 545, thereby assisting in guiding the alloy wire, that is, the alloy wire can return to the position opposite to the die hole of the wire drawing die 546 after passing through the wire slot 545, and the degree of left and right skew is reduced.

[0073] Referring to Figure 6 and Figure 7 , the die seat assembly 5 further comprises two sets of locking mechanisms 53 symmetrically mounted on the side wall of the I-shaped frame 51, and the square support rod 52 is located between the two sets of locking mechanisms 53. After the plurality of coupling blocks 541 are arranged, the plurality of coupling blocks 541 are locked by the two sets of locking mechanisms 53, so that the plurality of coupling blocks 541 can form a spliced whole, and the stability between the plurality of coupling blocks 541 during the drawing process of the alloy wire is ensured. The specific structure of the locking mechanism 53 is as follows:

[0074] Referring to Figures 6-11 , the two sets of locking mechanisms 53 each comprise an L-shaped plate 531, the side wall of the L-shaped plate 531 is provided with a sliding groove 532, the side, away from the square support rod 52, of the sliding groove 532 is rotationally connected with a bidirectional screw rod 534, the outer side wall of the bidirectional screw rod 534 is threadedly connected with two clamping plates 533, the two clamping plates 533 are arranged in the inside of the corresponding sliding groove 532, the side wall of the I-shaped frame 51 is provided with a clamping groove 535, and one side of the L-shaped plate 531 is arranged in the inside of the clamping groove 535.

[0075] When the plurality of connecting blocks 541 are sleeved on the outer wall of the square support rod 52, one end of the two L-shaped plates 531 is inserted into the corresponding clamping groove 535, and the plurality of connecting blocks 541 are arranged between the two L-shaped plates 531. Then, the worker rotates the bidirectional screw rod 534 to make the two clamping plates 533 slide in the corresponding sliding groove 532 and approach each other, thereby extruding and fixing the splicing of the plurality of connecting blocks 541. Then, the worker can perform the wire drawing operation of the tower wheel body 42 and the wire drawing die 546, which is convenient for subsequent alloy wire drawing.

[0076] When the tower wheel body 42 is a non-equal ratio stepped or multi-stage cylindrical combined type, the plurality of connecting blocks 541 are not arranged in a horizontal arrangement state, and two top pillars 544 are symmetrically connected at the bottom of the connecting block 541. The worker first sleeves the plurality of connecting blocks 541 on the outside of the square support rod 52, and then installs the locking mechanism 53. At this time, the locking mechanism 53 only guides the plurality of connecting blocks 541 but does not lock them.

[0077] Then, the worker places the mold base assembly 5 above the tower wheel assembly 4, and each connecting block 541 corresponds to the corresponding tower wheel groove on the outer wall of the tower wheel body 42. The two top pillars 544 at the bottom of each connecting block 541 are inserted into the corresponding tower wheel groove. Then, the mold base assembly 5 is pressed downward on the tower wheel body 42, which causes the plurality of connecting blocks 541 to be dislocated. The dislocation height changes to match the shape of the tower wheel body 42. After adjustment, the bidirectional screw rod 534 is rotated to make the two clamping plates 533 slide in the corresponding sliding groove 532 and approach each other, thereby extruding and fixing the splicing group of the plurality of connecting blocks 541, maintaining the splicing dislocation height of the plurality of connecting blocks 541. The dislocation height matches the shape of the selected tower wheel body 42 (non-equal ratio stepped or multi-stage cylindrical combined type).

[0078] Then, the worker installs the I-shaped frame 51 on the inner side wall of the box body 12 and positions it by the locking bolt 55. Then, the worker can perform the wire drawing operation of the tower wheel body 42 and the wire drawing die 546, which is convenient for subsequent alloy wire drawing.

[0079] By arranging the plurality of connecting blocks 541, the mold base assembly 5 can match the shape of the tower wheel body 42. It is not necessary to process the mold base according to the shape of the tower wheel body 42 or adjust the angle of the inclined adjustment mold base. It can also be used with a non-equal ratio stepped tower wheel body 42.

[0080] At the same time, in the actual drawing process, the alloy wire needs to be reduced in diameter by the wire drawing die 546. However, once the wire drawing die 546 is worn, the service life of the wire drawing die 546 will be greatly reduced. The worker needs to repeatedly adjust the position of the wire drawing die 546 to reduce the degree of wear. However, the error is large when adjusting manually.

[0081] By setting the chamfer of the wire slot 545 and adjusting the height of the coupling block 541, the relative position of the die hole of the drawing die 546 and the tower wheel groove of the tower wheel body 42 can be further adjusted, that is, the position of the left and right skew of the alloy wire entering the die hole of the drawing die 546 is limited by the chamfer of the wire slot 545, and the relative position of the height of the alloy wire extending out of the tower wheel groove and the die hole of the drawing die 546 is adjusted by the height adaptability of the coupling block 541, thereby reducing the eccentric wear of the alloy wire when entering the die hole of the drawing die 546.

[0082] In the third embodiment, after the die holder assembly 5 is improved, it is also considered that the width and spacing of the tower wheel groove of different tower wheel bodies 42 will cause the spacing of the alloy wire winding to change, therefore, the splicing of the conventional coupling block 541 is not completely applicable to the use of different tower wheel bodies 42.
