[0048] In the related art, the wire drawing process of the rolling roll mainly performs surface treatment on the rolling roll by means of laser.

[0051] The following uses specific embodiments to elaborate in detail on the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems. These several specific embodiments below can be combined with each other, and for the same or similar concepts or processes, they may not be repeated in some embodiments. The following will describe the embodiments of the present application in conjunction with the drawings.

[0052] Figure 1 It is a schematic structural diagram of the wire drawing device for the mold provided by the embodiments of the present application. Figure 2 For Figure 1 The schematic structural diagram of removing the adjustment component in

[0053] This embodiment provides a wire drawing device for a mold, including a first support member 100; a rotating shaft 200, which is arranged on the first support member 100 and can rotate relative to the first support member 100; a tool holder 300, which is arranged on the rotating shaft 200, and the tool holder 300 has at least one mounting portion 310; at least one set of cutting tools 400, the cutting tools 400 are correspondingly arranged on the mounting portion 310, and the cutting tools 400 are configured to cut and form a wire drawing portion on the rolling piece 10 that rotates in the same direction as the rotating shaft 200 under the drive of the rotating shaft 200.

[0054] Specifically, in the related art, during the wire drawing operation of metals, it is necessary to first process a wire drawing portion on the surface of the rolling piece 10, and then send the metal strip into a rolling mill, and under high pressure, the texture on the surface of the wire drawing portion is accurately imprinted on the metal surface, so as to form a wire drawing effect on the metal surface. However, in the laser processing process, the production cost is relatively high. At the same time, due to the easy difference in the fluidity of the local molten pool of the surface material of the rolling piece 10, unmolten particle residues or burrs are likely to be generated, resulting in an unsatisfactory wire pattern effect of the wire drawing portion on the rolling piece 10, so additional subsequent deburring and other work need to be carried out, which further increases the production cost and reduces the production efficiency.

[0055] Therefore, this embodiment provides a wire drawing device for a mold, which cuts the rolling piece 10 through the cutting tools 400 to ensure the smoothness and aesthetics of the wire drawing portion, and at the same time can reduce the production cost.

[0056] Specifically, in this embodiment, the wire drawing device for the mold includes a first support member 100 and a rotating shaft 200. The first support member 100 serves as a support structure for the rotating shaft 200 to ensure the stability of the rotating shaft 200 during rotation.

[0057] In this embodiment, the number of the first support members 100 is two, and the two first support members 100 are respectively rotatably connected to both ends of the rotating shaft 200, so as to achieve two-point support for the rotating shaft 200, reduce the radial runout of the rotating shaft 200 during high-speed rotation, and ensure the stability of the rotating shaft 200.

[0058] Specifically, in this embodiment, through holes are formed in the first support member 100, bearings are arranged at both ends of the rotating shaft 200, and the bearings are fixed in the through holes to achieve the rotational connection between the rotating shaft 200 and the first support member 100.

[0059] In this embodiment, the tool holder 300 is sleeved on the rotating shaft 200 to rotate under the drive of the rotating shaft 200. Among them, the tool holder 300 and the rotating shaft 200 can be connected by connection methods such as key grooves and splines to ensure the synchronism of the rotation of the tool holder 300 and the rotating shaft 200.

[0060] The tool rest 300 provided in this embodiment has at least one mounting portion 310, and at least one set of cutting tools 400 is arranged on the mounting portion 310. Among them, the mounting portion 310 is a mounting platform for the cutting tool 400, and the cutting tool 400 is arranged on the mounting portion 310.

[0061] Among them, the number and arrangement mode of the mounting portions 310 can be adaptively selected according to actual needs. One set or multiple sets of cutting tools 400 can be arranged on each mounting portion 310 to achieve different wire drawing effects.

[0062] In an optional embodiment, a tapered groove matching the number and shape of the cutting tools 400 can be opened on the mounting portion 310. The automatic centering is realized by the cooperation of the tapered surface of the tapered groove and the tapered shank of the cutting tool 400, so as to ensure the coaxiality of the installation of the cutting tool 400, ensure the installation accuracy of the cutting tool 400, and avoid the problem of unsatisfactory cutting effect caused by the vibration of the cutting tool 400 during the cutting process.

[0063] In an optional embodiment, a stepped groove is opened on the mounting portion 310, and the size of the stepped groove is set to match cutting tools 400 of different sizes, so as to realize the installation of cutting tools 400 of different sizes.

[0064] Specifically, during the actual working process, as the rotating shaft 200 rotates, the cutting tools 400 on the tool rest 300 continuously rotate driven by the rotating shaft 200, so as to perform cutting and wire drawing processing on the surface of the workpiece to be rolled, so as to form a wire drawing portion, which is convenient for subsequent wire drawing processing of the metal strip by the rolled piece.

[0065] In an optional embodiment, it further includes a rotating member 20. The rotating member 20 is arranged opposite to the tool rest 300, and the rolled piece 10 is arranged on the rotating member 20 facing the cutting tool 400 to rotate driven by the rotating member 20.

[0066] Specifically, in this embodiment, the rolled piece 10 rotates in the same direction as the rotating shaft 200 driven by the rotating member 20. Since the rotating directions of the cutting tool 400 and the rolled piece 10 are the same, the relative cutting speed between the two is more stable, avoiding vibration or impact caused by sudden speed change during reverse cutting, thereby reducing the tremor of the cutting tool 400 and ensuring the smoothness of the processing process. At the same time, it can also ensure the coherence of the cutting trajectory of the cutting tool 400 and ensure the surface effect of the wire drawing portion.

[0067] In an optional embodiment, the outer contour of the tool rest 300 is constructed as a circle, and at least one set of cutting tools 400 is arranged on the circumferential side of the tool rest 300.

[0068] In this way, when the tool rest 300 rotates in the same direction as the rotating shaft 200, the contact point between the tool 400 and the rolled piece 10 is relatively fixed. Thus, the tool 400 can contact the surface of the rolled piece 10 with a stable tangential force, reduce the relative speed difference through synchronous rotation, avoid cutting vibration. At the same time, the circumferential distribution of multiple tools 400 can cover a wider processing area, so as to efficiently complete the etching of uniform texture in a single pass, improving the processing accuracy and efficiency.

[0069] In an optional embodiment, at least one set of mounting holes 311 arranged along the axial direction of the rotating shaft 200 are formed on each mounting portion 310, and adjacent two sets of mounting holes 311 are arranged in a staggered manner. Each tool 400 is correspondingly inserted into each mounting hole 311.

[0070] Specifically, in this embodiment, mounting holes 311 corresponding to the tools 400 are formed on each mounting portion 310. Each set of tools 400 corresponds to a set of mounting holes 311 respectively, and each tool 400 is correspondingly mounted in the mounting hole 311 one by one, and adjacent two sets of mounting holes 311 are arranged in a staggered manner, that is, a set of mounting holes 311 has an offset setting relative to its adjacent set of mounting holes 311, so that the silk patterns can be more uneven and uniform during the cutting process, avoiding the situation that adjacent two sets of tools 400 repeatedly cut at the same position of the rolled piece 10, resulting in problems such as repeated knives causing the silk patterns to be distorted or bright wires appearing.

[0071] Exemplarily, in this embodiment, each set of mounting holes 311 has an offset of 1 - 3 mm relative to the adjacent set of mounting holes 311. Specifically, each set of mounting holes 311 has a horizontal position offset of 1 - 3 mm in the circumferential direction relative to the adjacent set of mounting holes 311, but the central axes of each mounting hole 311 remain parallel, so as to ensure that the drawn wire patterns formed by the tools 400 on the surface of the rolled piece 10 are all straight lines, but there will be a slight position difference between the patterns of adjacent sets.

[0072] That is, when the first set of tools 400 pulls out the first set of straight wire patterns on the surface of the rolled piece 10, due to the installation position of the second set of tools 400 being offset by 1 - 3 mm, the second set of straight wire patterns will be pulled out in the parallel direction, maintaining a fixed distance from the first pattern. Thus, through the continuous processing of multiple sets of tools 400, a group of parallel straight wire patterns with uniform distribution is finally formed on the surface of the rolled piece 10, avoiding the problem of repeated knives caused by multiple sets of tools 400 repeatedly processing the same pattern, ensuring both the clarity of the pattern and improving the processing efficiency.

[0073] At the same time, by adjusting the offset and the interval between adjacent tools 400, the density of the wire patterns on the surface of the rolled piece 10 can be controlled to meet different processing requirements.

[0074] In an alternative embodiment, a limiting member 500 is further included. An installation space is formed between two adjacent installation parts 310. A plurality of limiting holes 312 are further formed in the installation part 310. Each limiting hole 312 is arranged in one-to-one correspondence with each installation hole 311 to connect the installation hole 311 with the installation space. One end of the limiting member 500 passes through the limiting hole 312 and extends into the installation hole 311 to abut against the tool 400, so as to lock the insertion depth of the tool 400 in the corresponding installation hole 311.

[0075] Specifically, in this embodiment, the limiting hole 312 and the installation hole 311 are in one-to-one correspondence and communication. By inserting the limiting member 500 into the limiting hole 312 to abut against the tool 400, the tool 400 can be fixed and limited, avoiding the tool 400 from shaking or radially moving during rotation.

[0076] In this embodiment, an external thread is provided at the root of the tool 400, and an internal thread is provided in the installation hole 311. The external thread and the internal thread are meshed with each other. The tool 400 is fixed by screwing the root of the tool 400 into the installation hole 311. Further, by sequentially inserting the limiting member 500 into the limiting hole 312 and the installation hole 311 to abut against the tool 400, the tool 400 is tightly fixed.

[0077] Among them, in this embodiment, the limiting member 500 is a bolt, and an internal thread matching the bolt is provided in the limiting hole 312. By controlling the screwing depth of the limiting member 500, the pressing force of the limiting member 500 on the tool 400 can be adjusted.

[0078] In addition, by adjusting the depth of the tool 400 screwed into the installation hole 311, the installation depth of the tool 400 can also be adjusted, so as to perform cutting on the rolled piece 10 at different depths.

[0079] At the same time, by forming an installation space between two adjacent installation parts 310, it is convenient for the operator to install the limiting member, and then adjust the insertion depth of the tool 400, improving the installation efficiency.

[0080] In an alternative embodiment, the wire drawing device of the mold further includes a base 600 and a moving assembly 700. The moving assembly 700 is arranged on the base 600 and is connected to the first support member 100. The moving assembly 700 is configured to drive the first support member 100 to move relative to the base 600 to adjust the cutting distance between the tool holder 300 and the rolled piece 10.

[0081] Specifically, in this embodiment, the wire drawing device of the mold further includes a base 600 and a moving component 700. The moving component 700 is connected to the first support member 100, so as to be able to drive the first support member 100 to move relative to the base 600, thereby adjusting the distance between the wire drawing device of the mold and the rolling piece 10, and thus realizing the adjustment of the wire drawing depth. At the same time, by adjusting the distance between the wire drawing device of the mold and the rolling piece 10, rolling pieces 10 with different diameters can be matched.

[0082] Specifically, the rolling piece 10 is usually a roll. When it is necessary to replace rolls with different diameters, the entire first support member 100 and components thereon such as the rotating shaft 200 and the tool holder 300 can be driven by the moving component 700 to move as a whole, so as to adjust the relative position between the tool 400 and the rolling piece 10, and avoid interference between the rolling piece 10 and the tool 400.

[0083] At the same time, when it is necessary to adjust the wire drawing depth, the moving component 700 can be used to drive the first support member 100 to move relative to the base 600, so as to adjust the distance between the tool 400 and the rolling piece 10, and further realize the adjustment of the cutting depth.

[0084] In an alternative embodiment, the moving component 700 includes a slide rail 710 disposed on the base 600 along the length direction of the base 600; a moving member 720 slidably connected to the slide rail 710, and the first support member 100 is disposed on the moving member 720; a driving member 730 connected to the moving member 720, and the driving member 730 is configured to drive the moving member 720 to slide along the slide rail 710.

[0085] Specifically, in this embodiment, the first support member 100 is disposed on the moving member 720, and the moving member 720 is slidably engaged with the slide rail 710 on the base 600, so as to drive the first support member 100 to slide relative to the base 600. The driving member 730 is connected to the moving member 720 to drive the moving member 720 to slide along the slide rail 710. Thus, through the arrangement of the driving member 730, the sliding distance of the moving member 720 can be accurately controlled, and further the depth of the wire pattern of the wire drawing part can be accurately controlled, ensuring the processing accuracy.

[0086] Specifically, in this embodiment, the driving member 730 is a push rod motor, and the output end of the push rod motor is connected to the moving member 720 to drive the moving member 720 to slide along the slide rail 710.

[0087] In other embodiments, the structure of the driving member 730 can also be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this.

[0088] Exemplarily, the driving member 730 is a threaded rod, and a threaded groove is formed on the moving member 720, and the threaded rod is inserted into the threaded groove and meshes with the threaded groove.

[0089] Specifically, in this embodiment, the driving member 730 is a threaded rod, and the threaded rod is screwed into the threaded groove on the moving member 720. When the threaded rod is rotated, since the moving member 720 is slidingly constrained by the slide rail 710 and cannot rotate, the thread meshing effect forces the moving member 720 to move linearly along the slide rail 710, thereby driving the entire first support member 100 to move forward or backward.

[0090] Specifically, in this embodiment, a handle is provided on the threaded rod, and the operator can rotate the threaded rod by rotating the handle. At the same time, to prevent the threaded rod from moving synchronously with the moving member 720, a fixing member is also provided in this embodiment. The fixing member is rotatably connected to the threaded rod to limit the position of the threaded rod.

[0091] In addition, in an alternative embodiment, a scale is provided on the base 600, and the operator can determine the current distance of the moving member 720 relative to the rolled piece 10 by comparing the scale at the position of the moving member 720.

[0092] In another embodiment, the threaded rod is connected to a motor, and the threaded rod is rotated by the motor to realize the automatic control of the moving assembly 700, and the moving distance of the moving assembly 700 can also be accurately controlled.

[0093] In an alternative embodiment, the wire drawing device of the mold further includes an adjusting assembly 800. The adjusting assembly 800 has a reference surface, and the reference surface abuts against the cutting head of the cutter 400 to determine the installation height of the cutter 400.

[0094] Specifically, when installing the cutter 400, if there is a height difference between the cutting heads of the cutters 400, it will cause problems such as uneven wire patterns at the wire drawing part and uneven surface quality of the rolled piece 10.

[0095] Therefore, the wire drawing device of the mold provided in this embodiment further includes an adjusting assembly 800. When installing the cutter 400, the cutting head of the cutter 400 is sequentially abutted against the reference surface of the adjusting assembly 800, so as to ensure that the installation heights of the cutters 400 are the same by means of abutment, and ensure the unity of the wire drawing depth.

[0096] Among them, the reference surface can be a reference horizontal plane perpendicular to the axial direction of the rotating shaft 200 or a reference vertical plane coinciding with the axial direction of the rotating shaft 200. In this regard, it can be adaptively selected according to actual needs.

[0097] In an alternative embodiment, the adjusting assembly 800 includes an abutting member 820, the lower surface of the abutting member 820 forms a reference plane, and the tool tip of the tool 400 abuts against the reference plane; a second support member 810 is disposed on the moving assembly 700 or the base 600. The second support member 810 includes a support portion 811 and a telescopic portion 812. One end of the telescopic portion 812 is connected to the abutting member 820, and the other end is slidably disposed within the support portion 811.

[0098] Specifically, in this embodiment, the adjusting assembly 800 includes a second support member 810 and an abutting member 820. Among them, the second support member 810 can be disposed on the moving assembly 700 or on the base 600, and the abutting member 820 is disposed directly above the tool rest 300. At the same time, the lower surface of the abutting member 820 is a horizontal reference plane. When installing the tool 400, the operator can first install the tool 400 on the tool rest 300, and then make the tool 400 contact the lower surface of the abutting member 820, so as to ensure that each tool 400 is at the same working height.

[0099] By adopting the adjusting assembly 800 provided in this embodiment, the adjusting assembly 800 is limited through the second support member 810 and the abutting member 820, ensuring the uniformity of the installation height of the tool 400. At the same time, without a complex adjustment process, the installation efficiency of the tool 400 is guaranteed.

[0100] In addition, in this embodiment, the second support member 810 includes a support portion 811 and a telescopic portion 812. One end of the telescopic portion 812 is connected to the abutting member 820, and the other end is slidably disposed within the support portion 811.

[0101] Specifically, in this embodiment, the second support member 810 includes a support portion 811 and a telescopic portion 812. Among them, the support portion 811 is a hollow structure, the lower end of the telescopic portion 812 is slidably nested in the inner cavity of the support portion 811, and the upper end is connected to the abutting portion. The abutting member 820 is lifted and lowered by the up and down sliding of the telescopic portion 812.

[0102] When it is necessary to adjust the installation height of the tool 400, the extension length of the telescopic portion 812 relative to the support portion 811 can be adjusted so that the lower surface of the abutting member 820 reaches a preset height.

[0103] In an alternative embodiment, a scale is further provided on the telescopic portion 812. The scale is longitudinally disposed along the outer surface of the telescopic portion 812. By observing the reading of the scale, the current height position of the abutting member 820 can be directly read, so as to quickly confirm the lifting height of the abutting member 820.

[0104] In an alternative embodiment, a push rod motor is provided inside the support portion 811, and the output end of the push rod motor is connected to the telescopic portion 812. When the reference height needs to be adjusted, the push rod motor starts to work, driving the telescopic portion 812 to rise or fall along the inner cavity of the support portion 811, so that the stop position of the abutting member 820 can be accurately controlled, realizing stepless height adjustment of the abutting member 820.

[0105] In an alternative embodiment, the second support member 810 further includes a positioning member (not shown). A first positioning hole 8111 is formed on the support portion 811, and a plurality of second positioning holes 8121 are evenly and spacedly formed on the telescopic portion 812. The positioning member is sequentially disposed through the first positioning hole 8111 and one of the second positioning holes 8121 to lock the relative positions of the support portion 811 and the telescopic portion 812.

[0106] Wherein, in this embodiment, the second support member 810 further includes a positioning member, and a series of equidistantly distributed second positioning holes 8121 are correspondingly formed on the telescopic portion 812, thereby realizing multi-stage height adjustment. During actual operation, the height can be roughly adjusted by sliding the telescopic portion 812 first, and then the corresponding second positioning hole 8121 is selected, and the positioning member is sequentially disposed through the first positioning hole 8111 and the second positioning hole 8121 for precise positioning. Thus, not only the rapid lifting and reliable locking of the abutting member 820 are realized, but also multiple preset reference heights can be provided according to the requirements of different specifications of the tool 400, greatly improving the adaptability and operation convenience of the adjusting assembly 800.

[0107] By adopting the wire drawing device of the mold provided in this embodiment, by adjusting the lifting distance of the telescopic portion 812 relative to the support portion 811, the height position of the abutting member 820 can be flexibly adjusted, so as to make adaptive settings according to different processing requirements. When it is necessary to process rolling pieces 10 with different diameters or change the wire drawing depth, the extension amount of the telescopic portion 812 can be adjusted accordingly, so that the abutting member 820 stays at the required working height, and then the installation heights of the respective tools 400 are adjusted.

[0108] Finally, it should be noted that: those skilled in the art will easily think of other implementation schemes of the present invention after considering the specification and practicing the present invention disclosed herein.
