Description

Technical Field

[0001] The invention belongs to the field of diamond wire manufacturing, and in particular relates to a tail die ring diameter adjustment device. Background Art

[0002] Diamond wire drawing is a process that passes a thick metal wire (usually tungsten) through a series of dies with gradually decreasing diameters to form a thin, long, hard and strong diamond wire. This technology is widely used in the precision cutting of hard and brittle materials such as solar photovoltaic panels, sapphire, and silicon wafers. The high quality and high precision of the diamond wire are crucial to ensure the cutting effect.

[0003] In the drawing and manufacturing process of the diamond wire busbar, the coil shape (warping) refers to the shape characteristics of the finished tungsten wire after it is wound into a coil, especially whether the tungsten wire is straight and whether there are bends, twists, etc. The quality of the coil shape directly affects the uniformity and cutting quality of the subsequent diamond wire. The main factors affecting the coil shape include the assembly accuracy of the wire drawing machine, the verticality of the mold and the tungsten wire, etc.

[0004] The perpendicularity between the die and the diamond wire refers to the perpendicular relationship between the die centerline and the tungsten wire feed direction during the drawing process. This parameter is critical to ensure that the tungsten wire can be formed evenly and straight when passing through the die. Poor perpendicularity will cause uneven force on the tungsten wire, causing inconsistent wire diameter, increased surface roughness and other problems, thus affecting the quality and stability of the final product.

[0005] In order to ensure the verticality between the die and the tungsten wire, the existing diamond wire drawing process mostly uses manual adjustment for the tail die diameter adjustment. The operator needs to manually adjust the position of the tail die or replace the tail die of different specifications according to the actual situation. This method relies on the experience and technical level of the operator, is prone to human errors, and has a slow adjustment speed, which is difficult to meet the needs of efficient production. Manual adjustment and limited freedom make it difficult to achieve the ideal adjustment accuracy, especially in a production environment with high precision requirements. This limitation is particularly obvious. The instability of the die position during the adjustment process will cause uneven force on the tungsten wire when passing through the die, increase the risk of wire breakage, and affect production efficiency and product quality.

[0006] The existing mold bracket with adjustment function limits the rotation freedom of the mold in some directions. Although this design can meet the basic adjustment needs to a certain extent, it is often unable to achieve fine multi-dimensional adjustment in actual production, resulting in insufficient adjustment accuracy and affecting the coil shape and straightness of the tungsten wire. Summary of the invention

[0007] The purpose of the present invention is to provide a tail die ring diameter adjustment device to solve the technical problem of high-degree-of-freedom adjustment of the die in multiple directions.

[0008] To achieve the above purpose, the specific technical solution of a tail mold ring diameter adjustment device of the present invention is as follows:

[0009] A tail mold ring diameter adjustment device includes a base and a tail mold bracket connected to the base through a plurality of adjustment parts; the tail mold bracket is used to place the tail mold for the diamond wire to be pulled to pass through, the tail mold bracket is provided with an adjustment surface protruding along the direction of pulling out the diamond wire, the base is provided with a concave supporting surface relative to the adjustment surface, and the adjustment surface adjusts the angle of the tail mold bracket relative to the base along the supporting surface to achieve vertical adjustment of the tail mold and the diamond wire to be pulled.

[0010] As a further improvement of the present invention, the adjustment surface and the support surface are correspondingly matched hemispherical shapes.

[0011] As a further improvement of the present invention, after the adjustment surface contacts the support surface, an adjustment gap exists between the tail mold support and the base, and the adjustment member passes through the adjustment gap to connect the tail mold support and the base.

[0012] As a further improvement of the present invention, the surface of the tail mold bracket is evenly spaced along the periphery of the adjustment surface with adjustment holes for the adjustment member to pass through. The adjustment holes are an even number and are symmetrically arranged relative to the inner hole of the tail mold. Connecting holes are arranged on the surface of the base corresponding to the adjustment holes, and the adjustment member enters the connecting holes after passing through the adjustment holes.

[0013] As a further improvement of the present invention, by adjusting the penetration degree of the adjusting member in the symmetrical adjusting hole, the corresponding adjustment gap is adjusted to adjust the verticality of the tail mold and the diamond wire to be drawn.

[0014] As a further improvement of the present invention, the number of the adjustment holes is 4, and pairs of the adjustment holes are symmetrically arranged relative to the inner hole of the tail mold.

[0015] As a further improvement of the present invention, the adjusting member is a bolt, which passes through the adjusting hole and enters the connecting hole, and the two symmetrical bolts are loosened and tightened to achieve angle adjustment of the tail mold bracket relative to the base.

[0016] As a further improvement of the present invention, the tail mold is fixed inside the tail mold bracket, and the inner hole of the tail mold is aligned with the center of the spherical cross-section of the adjustment surface.

[0017] As a further improvement of the present invention, the adjusting member has a locking function to lock the relative position between the tail mold support and the base after the adjustment is completed.

[0018] As a further improvement of the present invention, a sensor is provided on the tail mold bracket for detecting the verticality of the tail mold and the diamond wire to be drawn.

[0019] Beneficial effects:

[0020] By providing a hemispherical adjustment surface and a support surface, as well as evenly spaced adjustment holes, the present invention can achieve fine adjustment of the tail mold support in multiple directions. This multi-dimensional adjustment capability ensures the verticality of the tail mold and the diamond wire to be drawn, and improves the accuracy and stability of the drawing process.

[0021] Fine adjustment through symmetrical adjustment holes helps ensure that the diamond wire remains straight as it passes through the tail die, avoiding deviation and distortion, thereby improving cutting quality.

[0022] A sensor is installed on the tail mold bracket to detect the verticality of the tail mold and the diamond wire to be drawn in real time. This real-time monitoring function helps to detect and correct deviations in time to ensure the stability and consistency of the production process.

[0023] The adjustment piece has a locking function, which can lock the relative position between the tail mold bracket and the base after the adjustment is completed to prevent loosening during use. This locking mechanism ensures the durability and reliability of the adjustment effect.

[0024] Through a simple bolt adjustment and locking mechanism, operators can easily make multi-dimensional adjustments without complicated tools or expertise. This easy operation improves production efficiency and reduces human error.

[0025] Multi-dimensional fine adjustment and high-precision control ensure the straightness and uniformity of the diamond wire, thereby improving the quality of the final product. This is especially important for high-precision diamond wire drawing and cutting applications.

[0026] The adjusting device of the present invention is suitable for tail molds and diamond wires of different specifications, has strong adaptability, can meet different production requirements through simple adjustment, and improves the flexibility and versatility of the equipment.

[0027] By accurately adjusting the verticality of the tail mold and the diamond wire, the scrap rate caused by poor verticality can be significantly reduced, production efficiency and economic benefits can be improved, the workload of operators can be reduced, and the level of production automation can be improved.

[0028] In summary, the present invention provides a tail die ring diameter adjustment device that can achieve multi-dimensional fine adjustment, has the advantages of high precision, automation, easy operation, strong durability, etc., can significantly improve the quality and efficiency of diamond wire drawing, and has broad application prospects.

[0034] In order to better understand the purpose, structure and function of the present invention, a tail mold ring diameter adjustment device of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0035] Implementation example:

[0036] like Figure 1 The tail mold circle diameter adjustment device shown is used to adjust the verticality of the tail mold 50 and the diamond wire 60 during the drawing process of the diamond wire 60. The base 10 is set on the operating platform as the overall support of the entire device, and the tail mold bracket 20 is used to place the tail mold 50. The diamond wire 60 passes through the inner hole 51 of the tail mold to complete the wire diameter change.

[0037] The tail mold support 20 protrudes toward the base 10 along the drawing direction of the diamond wire 60, and the protruding end is the adjustment surface 21. The base 10 is concave toward the adjustment surface 21, and the concave end is the support surface 11. The adjustment surface 21 and the support surface 11 are correspondingly matched hemispherical shapes. After the adjustment surface 21 contacts the support surface 11, it can rotate along the support surface 11. After the adjustment surface 21 contacts the support surface 11, an adjustment gap 40 is formed between the base 10 and the tail mold support 20. By adjusting the width of the adjustment gap 40, the relative angle between the tail mold support 20 and the base 10 changes, driving the angle adjustment of the tail mold 50 and the diamond wire 60 on the tail mold support 20.

[0038] The base 10 is connected to the tail mold support 20 through an adjusting member 30. In this embodiment, the adjusting member 30 is a bolt. Figure 2-3 As shown, the tail mold bracket 20 is provided with adjustment holes 22 at even intervals along the periphery of the adjustment surface 21, the adjustment holes 22 are provided in an even number, and the corresponding two adjustment holes 22 are symmetrically arranged relative to the tail mold inner hole 51, and the positions of the adjustment holes 22 are provided with connecting holes 12 along the periphery of the supporting surface 11 on the base 10, and the adjustment holes 22 and the connecting holes 12 are provided with internal threads corresponding to the external threads of the bolts, and the bolts pass through the adjustment holes 22 and enter the connecting holes 12, and the tail mold bracket 20 is fixed by tightening one side of the bolts, and the adjustment gap 40 is adjusted by loosening and tightening the bolts.

[0039] In this embodiment, adjustment holes 22 are provided at the four corners of the square tail mold support 20, and the adjustment holes 22 are symmetrically arranged relative to the tail mold inner hole 51. Figure 4 As shown, by adjusting the tightness of the bolts in the two symmetrical adjustment holes 22, the tail mold bracket 20 can be rotated and adjusted in four directions. A laser sensor is provided on the tail mold bracket 20 to detect the verticality of the tail mold 50 and the diamond wire 60. When the verticality of the diamond wire 60 and the inner hole 51 of the tail mold meets the standard, the bolts are tightened to fix the angle of the tail mold bracket 20 relative to the base 10, and the drawing production of the diamond wire 60 begins.

[0040] The diamond wire tilts in the machine due to unavoidable factors such as machine assembly, part size errors, and diamond wire diameter. The mold and tungsten wire are not in vertical contact, and the wire loop is poor. The device of the present invention can adjust the contact between the tungsten wire and the mold back to vertical through a high-freedom mold angle adjustment device, thereby increasing the loop diameter. The design of the spherical adjustment surface and the support surface allows the tail mold bracket to be finely adjusted in multiple directions to ensure the verticality of the tail mold and the diamond wire, while the existing devices are mostly plane adjustments with limited adjustment range and accuracy. The close fit between the spherical adjustment surface and the support surface, combined with the use of bolts and sensors, can achieve higher adjustment accuracy. The spherical adjustment design makes the operation easier, and multi-dimensional precise adjustment can be achieved through simple bolt adjustment, while the operation of the existing device is complicated and requires a higher technical level. The spherical adjustment design is suitable for tail molds and diamond wires of different specifications, and has strong adaptability, while the existing device has poor adaptability and requires frequent replacement of tail molds of different specifications.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
