Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing, in particular to a wire drawing die centering device. Background Art

[0002] The microfilament drawing process is a critical step in producing high-precision, high-performance wire. However, in actual production, improper wire drawing die installation or wear during use often causes the die hole to become misaligned with the wire axis, leading to a series of problems. For example, this misalignment between the die hole and the wire leads to uneven circumferential stress distribution in the die, which in turn causes uneven drawing force on the wire, ultimately resulting in the drawn wire being crooked or failing to meet dimensional accuracy requirements. These issues not only affect product quality but also reduce production efficiency and increase costs.

[0003] Currently, the main approach to wire drawing die alignment is to manually adjust the die's installation angle based on the operator's experience, attempting to align the die hole with the wire. This manual adjustment method is highly dependent on the operator's experience and skill level, is highly subjective, and prone to errors. This is particularly true for micron-level precision drawing, where manual adjustment struggles to achieve the required high precision. Furthermore, the manual adjustment process lacks real-time monitoring and feedback mechanisms, and the effectiveness of adjustments can only be indirectly verified through the quality of the finished product, preventing immediate confirmation of alignment during the adjustment process.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments, but those skilled in the art will understand that the embodiments described below are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to illustrate the present invention, and should not be regarded as limiting the scope of the present invention.

[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] See also Figure 1 , the utility model provides a wire drawing die centering device, comprising: a drawing device 1, a light emitting device and a display device;

[0036] Light emitting devices are symmetrically arranged on both sides of the drawing device 1. The light emitting devices are used to emit light beams and project the image of the wire passing through the drawing device 1 onto the display device.

[0037] The wire enters the drawing device 1 from its inlet and exits from the outlet of the drawing device 1 after being reduced in diameter. Two light emitting devices are symmetrically located on both sides of the drawing device 1 to emit light beams and project the image of the wire onto the display device.

[0038] The wire drawing die centering device of the utility model utilizes a projection method to project the wire in the drawing process onto a display device, and by adjusting the angle of the wire drawing die, the wires on the left and right sides of the wire drawing die are projected on the same straight line, thereby achieving centering.

[0039] During the drawing process, two light-emitting devices project light beams onto the wire on either side of the drawing die and onto a display device. The images of the wire appear as two lines on the display, corresponding to the wire images on either side of the drawing die. The operator observes the wire images on the display. If the wires on either side of the drawing die are not aligned, the two lines on the display will also no longer be aligned, indicating that the die hole and the wire axis are not concentric. If the two lines are not aligned, the drawing die angle is adjusted so that the two lines on the display completely overlap, indicating that the drawing die and wire are concentric, and the alignment process is complete.

[0040] The wire drawing die centering device of the utility model utilizes the projection method to effectively solve the problem of non-concentricity between the die hole and the wire axis caused by improper die installation or die wear during the micro-wire drawing process, thereby ensuring uniform distribution of die stress during the drawing process and improving the straightness of the wire.

[0041] The wire drawing die centering device of the present invention utilizes projection technology to clearly display the projection of the wire on the display device, accurately display the deviation between the wire and the die, and achieve high-precision centering by adjusting the image of the wire to completely overlap on a straight line; moreover, it is capable of real-time monitoring and feedback, and can instantly confirm the centering effect during the adjustment process.

[0042] In some embodiments, the angle of the light emitting device is adjustable, and the adjustment angle of the light emitting device is 0° to 30°; for example, the adjustment angle of the light emitting device is 0°, 10°, 20°, 30°, and so on.

[0043] In some embodiments, the display device is disposed directly below the pulling device 1 ; preferably, the display device is horizontally disposed directly below the pulling device 1 .

[0044] When the drawing device 1 rotates in the horizontal plane, the light emitting device illuminates the silk thread from directly above the display device. At this time, if the projection of the silk thread in the display device is not in a straight line, it is necessary to adjust the left and right flipping angle of the drawing device 1 so that the projection of the silk thread returns to a straight line.

[0045] When the drawing device 1 rotates in a vertical plane, the light emitting device rotates a certain angle relative to the display device, and illuminates the silk thread obliquely. At this time, if the projection of the silk thread in the display device is not in a straight line, it is necessary to adjust the up and down flipping angle of the drawing device 1 so that the projection of the silk thread returns to a straight line.

[0046] In some embodiments, the light sources of the two light emitting devices located on both sides of the drawing device 1 are rotated and adjusted synchronously, which helps to ensure that the rotation angles of the light sources of the two light emitting devices are consistent, making the projection result more accurate.

[0047] The adjustment angle of the light emitting device is 0° to 30°, and the rotation adjustment angle should not be too large to prevent the projection from running outside the display device.

[0048] When the drawing die centering device is in use, the light emitting device can first illuminate from directly above the display device to detect the rotation of the drawing device 1 in the horizontal plane, and then the two light emitting devices can be synchronously adjusted to a certain angle to check the rotation of the drawing device 1 in the vertical plane.

[0049] In some embodiments, the light emitting device includes a laser emitter.

[0050] In some embodiments, a first laser emitter 2 is provided on one side of the drawing device 1, and a second laser emitter 3 is provided on the other side, and the first laser emitter 2 and the second laser emitter 3 are symmetrically distributed; the first laser emitter 2 is used to emit a laser beam and project the image of the inlet wire 5 on one side of the drawing die onto the display device to form a first projection 7; the second laser emitter 3 is used to emit a laser beam and project the image of the outlet wire 6 on the other side of the drawing die onto the display device to form a second projection 8.

[0051] In some embodiments, the display device includes a projection panel 4 .

[0052] In some embodiments, the projection board 4 is provided with a scale. Preferably, the projection board 4 is provided with horizontal scale lines. The projection board 4 has a precise horizontal scale to facilitate the operator to adjust according to the image of the silk thread.

[0053] The wire drawing die centering device of the present invention uses a projection method combined with laser technology to clearly display the projection of the wire on the projection plate 4, can intuitively observe the deviation of the wire, and can perform precise adjustments through horizontal scale lines to achieve high-precision centering.

[0054] The wire drawing die centering device of the utility model adopts laser projection technology and a projection plate 4 with a precise horizontal scale, so that an operator can easily complete the centering process without complicated instruments.

[0055] The wire drawing die centering device of the utility model can achieve high-precision centering, so that the force on the die is evenly distributed, avoiding the problem of die overload during the drawing process, further reducing die wear and wire bending, and improving the straightness and quality of the drawn product.

[0056] The wire drawing die of the utility model simplifies the centering operation process, is easy to operate, reduces the operation time, and improves production efficiency. It is particularly suitable for industrial scenarios of high-speed drawing of fine wires.

[0057] See also Figure 2 , in some embodiments, the drawing device 1 includes a die base 11, an adjusting component, a drawing die 12 and a support spring 13;

[0058] The support spring 13 and the drawing die 12 are arranged in the die base 11, and the drawing die 12 is located between the support spring 13 and the inner wall of the die base 11;

[0059] The adjusting component is provided on the die base 11 , and is used to adjust the angle of the drawing die 12 .

[0060] During the drawing process, the wire enters the drawing device 1 from the inlet, is reduced in diameter by the drawing die 12 in the drawing device 1 , and then is passed out from the outlet of the drawing device 1 .

[0061] In some embodiments, a plurality of support springs 13 are symmetrically provided on one side of the drawing die 12 ; the number of the support springs 13 can be 2, 4, etc., as long as the force on the drawing die 12 can be kept symmetrical.

[0062] In some embodiments, two support springs 13 are symmetrically arranged on one side of the drawing die 12; the symmetrical arrangement of the support springs 13 ensures the symmetrical distribution of the restraining force of the support springs 13 on the drawing die 12, avoiding the influence of unbalanced load on wire drawing during drawing.

[0063] Two support springs 13 and a drawing die 12 are provided in the die base 11. The two support springs 13 are installed in the die base 11. The drawing die 12 is embedded between the support springs 13 and the inner wall of the die base 11. The angle of the drawing die 12 can be adjusted by the adjustment component on the die base 11.

[0064] In some embodiments, the adjusting component includes a first adjusting component 14 and a second adjusting component 15 . The first adjusting component 14 is used to adjust the up and down flipping angle of the drawing die 12 , and the second adjusting component 15 is used to adjust the left and right flipping angle of the drawing die 12 .

[0065] The vertical and horizontal angles of the drawing die 12 can be adjusted by adjusting components on the die base 11. Adjusting the vertical angle of the drawing die 12 can align the two lines on the projection plate 4 in the vertical direction, and adjusting the horizontal angle of the drawing die 12 can align the two lines on the projection plate 4 in the horizontal direction.

[0066] In some embodiments, the adjustment component includes a micrometer.

[0067] In some embodiments, a first micrometer and a second micrometer are provided on the die base 11 . The first micrometer is used to adjust the up-and-down flipping angle of the drawing die 12 , and the second micrometer is used to adjust the left-and-right flipping angle of the drawing die 12 .

[0068] During the wire drawing process, the laser projects the wire onto the projection plate 4. If the two projections on the projection plate 4 are no longer in a straight line, the up and down, left and right angles of the drawing die 12 are fine-tuned by a micrometer until the projections of the wires at both ends of the drawing die 12 on the projection plate 4 are in a straight line, thereby achieving centering.

[0069] The novel wire drawing die centering device of this embodiment can achieve high-precision centering and can be used in the drawing of metal micro-wires, for example, for the drawing of bonding wires.

[0070] Example 1

[0071] The wire drawing die centering device provided in this embodiment includes: a drawing device 1, a first laser emitter 2, a second laser emitter 3 and a projection plate 4;

[0072] The first laser emitter 2 and the second laser emitter 3 are symmetrically distributed on both sides of the drawing device 1, and the projection plate 4 is horizontally arranged directly below the drawing device 1;

[0073] The first laser emitter 2 and the second laser emitter 3 are used to emit laser beams and project the image of the wire passing through the drawing device 1 onto the projection plate 4;

[0074] The angles of the first laser emitter 2 and the second laser emitter 3 are adjustable, and the adjustment angle is 0° to 30°;

[0075] The projection board 4 is provided with horizontal scale lines;

[0076] The drawing device 1 includes a die base 11, a first micrometer, a second micrometer, a drawing die 12 and two supporting springs 13;

[0077] Two support springs 13 and a drawing die 12 are arranged in the die base 11, and the drawing die 12 is embedded between the support springs 13 and the inner wall of the die base 11; the two support springs 13 are located on one side of the drawing die 12 and are symmetrically distributed;

[0078] The first micrometer and the second micrometer are set on the die base 11. The first micrometer is used to adjust the up-and-down flipping angle of the drawing die 12, and the second micrometer is used to adjust the left-and-right flipping angle of the drawing die 12.

[0079] The method for centering a wire drawing die using the above-mentioned wire drawing die centering device comprises the following steps:

[0080] S1. Start the drawing device 1, the first laser emitter 2, and the second laser emitter 3. The wire enters the inlet of the drawing device 1, is reduced in diameter by the drawing die 12, and then exits the outlet of the drawing device 1. The first laser emitter 2 and the second laser emitter 3 illuminate from directly above the projection plate 4. Alternatively, the angles of the first laser emitter 2 and the second laser emitter 3 are synchronously adjusted so that they are rotated a certain angle relative to the display device and illuminate at an angle. The first laser emitter 2 emits a laser beam and projects the image of the inlet wire 5 on one side of the drawing die 12 onto the projection plate 4, forming a first projection 7. The second laser emitter 3 emits a laser beam and projects the image of the outlet wire 6 on the other side of the drawing die 12 onto the projection plate 4, forming a second projection 8.

[0081] S2. Observe whether the first projection 7 and the second projection 8 on the projection plate 4 are in a straight line. If they are not in a straight line, it means that the drawing die hole and the wire are not concentric;

[0082] S3. When the first projection 7 and the second projection 8 are not in a straight line, fine-tune the up and down or left and right angles of the drawing die 12 by using the first micrometer or the second micrometer, and gradually adjust the drawing die 12 until the first projection 7 and the second projection 8 coincide, and the centering is completed.
