Description

Technical Field

[0001] This invention belongs to the field of metal wire forming technology, specifically relating to an integrated machine for cooling and drying metal wire forming. Background Technology

[0002] In the production and processing of metal wire, a specific aperture of a forming die is commonly used to draw the wire to obtain the required diameter and cross-sectional shape. Oil cooling is often used during the drawing process to cool and lubricate the wire. This oil cooling leaves a film on the surface of the cooled wire, which can adversely affect subsequent processing steps such as electroplating, spraying, or welding, thus impacting processing efficiency. Furthermore, during the drawing process, especially for wires with irregular cross-sections after forming, burrs are easily generated on the wire surface due to friction and plastic deformation. This directly affects the surface finish of the metal wire, reduces product grade, and may even affect the stability of subsequent assembly and use. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides an integrated metal wire forming, cooling and drying machine, which can improve the surface smoothness of the wire, reduce oil residue on the wire surface, and improve the processing quality of the wire.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] A metal wire forming, cooling, and drying integrated machine includes a forming mold and a drying unit. The wire passes through the forming mold and the drying unit in sequence and is then wound by a winding unit. During the drawing process through the forming mold, the wire is cooled by a cooling device containing a coolant. Crucially, the integrated machine also includes a first guide wheel assembly located between the forming mold and the drying unit. The first guide wheel assembly includes a first main wheel and a first auxiliary wheel mounted on a frame. A transmission belt, via the first auxiliary wheel and a tension wheel, is arranged around the first main wheel and forms a first recess. The first main wheel is located within the groove of the first recess. Polished layers are respectively provided on the adjacent surfaces of the transmission belt and the first main wheel, forming a guide channel for the wire between the polished layers of the transmission belt and the polished layers of the first main wheel.

[0006] The opening of the first recess is oriented upwards, and the opening of the first recess is connected to the liquid outlet end of the cleaning liquid dropper.

[0007] The first auxiliary wheel is connected to the frame via a first drive assembly. The first drive assembly includes a first telescopic cylinder and a first swing arm. The first swing arm is hinged to the frame. The first telescopic cylinder is mounted on the frame. The two ends of the first swing arm are respectively connected to the first telescopic cylinder and the first auxiliary wheel. The first auxiliary wheel has the freedom to swing back and forth toward the first main wheel by means of the drive of the first telescopic cylinder. The tension wheel adjusts the tension of the transmission belt by means of a second drive assembly.

[0008] The second drive assembly includes a second swing arm and a second telescopic cylinder. The second swing arm is hinged to the frame, and its two ends are respectively connected to the second telescopic cylinder and the tensioning wheel.

[0009] The integrated machine also includes a second guide wheel assembly, which shares a transmission belt with the first guide wheel assembly. The second guide wheel assembly includes a second main wheel and a second auxiliary wheel mounted on the frame. The transmission belt is arranged around the second main wheel via the second auxiliary wheel and a tension wheel to form a second recess. The second main wheel is located in the groove of the second recess. A polished layer is provided on the second main wheel. A guide channel for the silk threads is formed between the polished layer of the transmission belt and the polished layer of the second main wheel.

[0010] The linear speed of the first main wheel is V1, the linear speed of the second main wheel is V2, and the transmission speed of the transmission belt is V3, wherein V3 > V1 > V2, and V1 is the same as the winding speed of the yarn. The transmission direction of the first main wheel, the second main wheel, and the transmission belt is consistent with the conveying direction of the yarn.

[0011] A cooling groove is provided between the tensioning pulleys, and the transmission belt is connected to the tensioning pulleys through the cooling groove.

[0012] The drying unit includes a hot air blower, and an inner cylinder and an outer cylinder that are nested together. An annular cavity is formed between the ends of the inner cylinder and the outer cylinder by means of an end cap. A set of air outlets is provided on the inner cylinder. The yarn is connected to the winding unit through the cavity of the inner cylinder.

[0013] The beneficial effects of this invention are:

[0014] This invention adds a first guide wheel group and a second guide wheel group. After the shaped thread passes through the guide channel, the front and back sides of the thread abut against the polished layer of the first main wheel and the polished layer of the transmission belt, respectively. The first main wheel rotates and the transmission belt moves, and the polished layer polishes the surface of the thread, reducing burrs and oil film on the surface of the thread, thereby achieving cleaning and polishing of the thread.

[0015] The opening of the first recess is set upward, and the opening of the first recess is connected to the liquid outlet of the cleaning liquid dropper. The cleaning liquid dropper drips cleaning liquid into the groove of the first recess through the liquid outlet to help dissolve the oil stains on the surface of the thread.

[0016] The winding speed of the thread, the transmission speed V3 of the transmission belt, and the linear speed V2 of the second main wheel create a speed difference. The transmission belt and the second main wheel generate relative friction on the front and back sides of the thread, respectively, thus polishing both sides of the thread.

[0017] As the thread passes through the first and second guide wheel sets, it undergoes controlled repeated bending, gradually eliminating residual stress generated during the forming process and improving the stability and tensile strength of the thread. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] Specific implementation examples Figures 1-3As shown, this invention relates to an integrated metal wire forming, cooling, and drying machine, comprising a forming mold 2 and a drying unit 3. The wire 1 passes sequentially through the forming mold 2 and the drying unit 3 before being wound by a winding unit. During the drawing process through the forming mold 2, the wire 1 is cooled by a cooling device 5 containing a coolant. The cooling device 5 is a cooling tank containing cooling oil. The wire 1 is repeatedly drawn and cooled by passing through the forming mold 2 and the cooling tank, ultimately obtaining the desired cross-sectional shape and size of the wire 1. Crucially, the integrated machine adds a first guide wheel assembly 6 between the forming mold 2 and the drying unit 3. The first guide wheel assembly 6 includes a first main wheel 601 mounted on the frame 10 and a second... A first auxiliary wheel 602 and a transmission belt 7 are arranged around a first main wheel 601 via the first auxiliary wheel 602 and a tension wheel 8 to form a first recess 9. The first main wheel 601 is located in the groove of the first recess 9. Polishing layers are respectively provided on the adjacent surfaces of the transmission belt 7 and the first main wheel 601. A guide channel for the filament 1 is formed between the polishing layers of the transmission belt 7 and the polishing layers of the first main wheel 601. After being formed, the filament passes through the guide channel, and the front and back sides of the filament 1 abut against the polishing layers of the first main wheel 601 and the transmission belt 7, respectively. The first main wheel 601 rotates and the transmission belt 7 moves. The polishing layers polish the surface of the filament, reducing burrs and oil film on the surface of the filament 1, thereby achieving cleaning and polishing of the filament 1.

[0026] The opening of the first recess 9 is set upward, and the opening of the first recess 9 is connected to the liquid outlet of the cleaning liquid dropper 12. The cleaning liquid dropper 12 drips cleaning liquid into the groove of the first recess 9 through the liquid outlet to help dissolve the oil stains on the surface of the thread.

[0027] The first auxiliary wheel 602 is connected to the frame 10 via a first drive assembly. The first drive assembly includes a first telescopic cylinder 13 and a first swing arm 14. The first swing arm 14 is hinged to the frame 10. The first telescopic cylinder 13 is mounted on the frame 10. The two ends of the first swing arm 14 are connected to the first telescopic cylinder 13 and the first auxiliary wheel 602, respectively. The first auxiliary wheel 602 has the freedom to swing back and forth toward the first main wheel 601 via the drive of the first telescopic cylinder 13. The tension wheel 8 adjusts the tension of the transmission belt 7 via a second drive assembly. The first swing arm 14 has an L-shaped structure. The first swing arm 14 is hinged to the frame 10 via a first hinge shaft. The telescopic end of the first telescopic cylinder 13 can be adjusted to allow the first swing arm 14 to rotate axially around the first hinge shaft on the frame 10, thereby adjusting the distance between the first auxiliary wheel 602 and the first main wheel 601, thereby adjusting the clamping force of the first auxiliary wheel 602 and the first main wheel 601 on the wire 1, and adapting to wires 1 with different diameters and cross-sectional shapes.

[0028] The second drive assembly includes a second swing arm 16 and a second telescopic cylinder 17. The second swing arm 16 is hinged to the frame 10. Both ends of the second swing arm 16 are connected to the second telescopic cylinder 17 and the tensioning wheel 8, respectively. The second swing arm 16 has an L-shaped structure. The second swing arm 16 is hinged to the frame 10 via a second hinge shaft. The extension and retraction of the telescopic end of the second telescopic cylinder 17 can drive the second swing arm 16 to rotate axially around the second hinge shaft, adjusting the position of the tensioning wheel 8 on the frame 10 and adapting it to the position of the first auxiliary wheel 602 to achieve tensioning of the transmission belt 7.

[0029] Furthermore, the integrated machine also includes a second guide wheel assembly 15, which shares a transmission belt 7 with the first guide wheel assembly 6. The second guide wheel assembly 15 includes a second main wheel 1501 and a second auxiliary wheel 1502 mounted on the frame 10. The transmission belt 7 is arranged around the second main wheel 1501 via the second auxiliary wheel 1502 and the tension wheel 8 to form a second recess 18. The second main wheel 1501 is located in the groove of the second recess 18. A polished layer is provided on the second main wheel 1501. A guide channel for the thread 1 is formed between the polished layer of the transmission belt 7 and the polished layer of the second main wheel 1501. The second auxiliary wheel 1502 is the same as the first auxiliary wheel 602 and is also connected to the frame 10 via the first drive assembly. The clamping force of the second main wheel 1501 and the second auxiliary wheel 1502 on the thread 1 can be adjusted by the drive of the first drive assembly.

[0030] The linear speed of the first main wheel 601 is V1, the linear speed of the second main wheel 1501 is V2, and the transmission speed of the transmission belt 7 is V3, where V3 > V1 > V2. V1 is the same as the winding speed of the wire 1. When the wire 1 passes through the first guide wheel group 6 and the second guide wheel group 15, the winding speed of the wire 1 is the same as the linear speed of the first main wheel 601, ensuring the overall stability of the wire 1's transport. The winding speed of the wire 1 forms a speed difference with the transmission speed V3 of the transmission belt 7 and the linear speed V2 of the second main wheel 1501. The transmission belt 7 and the second main wheel 1501 generate relative friction on the front and back sides of the wire 1 respectively, achieving polishing of both sides of the wire 1.

[0031] The conveying direction of the first main wheel 601, the second main wheel 1501, and the transmission belt 7 is consistent with the conveying direction of the thread 1.

[0032] Preferably, the difference between the transmission speed V3 of the drive belt 7 and the linear speed V1 of the first main pulley 601 is less than the difference between the linear speed V1 of the first main pulley 601 and the linear speed V2 of the second main pulley 1501. Compared to the linear speed V2 of the second main pulley 1501, the transmission speed V3 of the drive belt 7 is closer to that of the first main pulley 601, and the transmission speed V3 of the drive belt 7 is closer to the winding speed of the yarn 1.

[0033] When the thread 1 passes through the first guide wheel group 6 and the second guide wheel group 15, it undergoes controllable repeated bending, gradually eliminating the residual stress generated during the forming process and improving the stability and tensile strength of the thread 1.

[0034] A cooling groove 11 is provided between the tensioning pulleys 8. The transmission belt 7 is driven by the tensioning pulleys 8 through the cooling groove 11. Preferably, a scraper is also provided at the outlet of the cooling groove 11 to abut against the polished layer of the transmission belt 7. The transmission belt 7 comes into contact with the cooling water in the cooling groove 11 as it passes through the cooling groove 11. When the transmission belt 7 is output from the cooling groove 11, the scraper squeezes the polished layer of the transmission belt 7 to remove the sewage on the transmission belt 7 and reduce the debris on the transmission belt 7.

[0035] Preferably, the drying unit 3 includes a hot air blower 301, and an inner cylinder 302 and an outer cylinder 303 that are nested together, such as... Figure 4 , Figure 5 As shown, an annular cavity is formed between the ends of the inner cylinder 302 and the outer cylinder 303 by means of an end cap. A set of air outlets 304 are provided on the inner cylinder 302. The wire 1 is connected to the winding unit through the cylinder cavity of the inner cylinder 302. After passing through the second guide wheel group 15, the wire 1 enters the cylinder cavity of the inner cylinder 302. The hot air blower 301 blows hot air into the annular cavity through the pipe. The hot air is sprayed into the cylinder cavity of the inner cylinder 302 through the air outlets 304 to dry the wire 1.
