Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a metal wire drawing machine. Background Technology

[0002] In the field of metal processing, wire drawing plays a crucial role. Through drawing, metal blanks are forced under tension through the die openings of a drawing mold, producing small-section metal wires of specific dimensions. This process is widely used in numerous industries and can manufacture metal wire products of various materials and specifications, such as copper, steel, and nickel wires.

[0003] In actual drawing processes, some metal materials, especially those with a close-packed hexagonal lattice, face significant difficulties when drawn at room temperature. To address this issue, existing technologies, such as the patent with authorization announcement number CN222198334U, propose a metal wire drawing device. This device consists of a drawing die, a processing box, and a heating mechanism. After the processing box is installed, the heating mechanism can be installed. When the user powers on the heating mechanism, the heat generated can heat the metal wire, softening its surface and reducing drawing resistance, thus facilitating the drawing of the metal wire through the drawing die.

[0004] However, in-depth research and practice have revealed certain limitations in the technical solutions provided by the aforementioned patents. One prominent issue is the short distance the metal wire remains inside the heating mechanism. This significantly reduces the heating time within the mechanism, preventing the wire from fully absorbing heat to achieve the desired softening effect. When drawing metal wires that require high heating levels, insufficient heating results in inadequate softening of the wire surface. Consequently, the wire still faces considerable resistance when passing through the drawing die, making it prone to breakage during drawing. This severely impacts product quality and production efficiency. Furthermore, the insufficient heating of the metal wire may necessitate repeated drawing operations, increasing energy consumption, further reducing production efficiency, and raising production costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a metal wire drawing machine, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal wire drawing machine, comprising a base plate, a feeding roller, and a take-up roller;

[0007] The pay-off roller and take-up roller are respectively installed on the left and right sides of the upper surface of the base plate. A linear guide rail is provided on the upper surface of the base plate, and a heating cylinder is driven to the linear guide rail to drive the heating cylinder to move left and right.

[0008] Mounting rings are installed on both the left and right sides of the inner wall of the heating cylinder, and a heating wire is provided between the opposite sides of the two mounting rings.

[0009] A support frame is installed on the base plate, and an installation plate is vertically installed inside the support frame.

Two horizontal plates are arranged parallel to each other on the right side of the installation plate, and a second guide wheel is provided on the opposite side of each of the two horizontal plates. An inclined bar is integrally formed at the right end of each of the two horizontal plates.

[0010] The two diagonal bars, the one furthest from the horizontal plate, are provided with the same guide tube.

[0011] Furthermore, the second guide wheels on the upper and lower sides are staggered left and right.

[0012] Furthermore, the right ends of both horizontal plates extend into the interior of the heating cylinder.

[0013] Furthermore, the heating wires are spirally distributed and sleeved on the outside of the two mounting plates.

[0014] Furthermore, a support wheel is installed on the lower diagonal bar.

[0015] Furthermore, a support base is installed on the upper surface of the base plate, and a connecting groove is opened vertically inside the support base. A wire-passing mold can be detachably installed inside the connecting groove.

[0016] Furthermore, a raised strip is integrally formed on both the front and rear sides of the die, and corresponding to the raised strip, a sliding groove is formed on both the front and rear sides of the inner wall of the connecting groove.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] 1. This metal wire drawing machine, by setting up second guide wheels on the upper and lower sides that are staggered left and right, makes the metal wire form a curved path when passing through, which increases the residence distance and heating time of the metal wire in the heating cylinder, solves the problem of short heating time of metal wire in the prior art, allows the metal wire to fully absorb heat, achieve the ideal softening effect, reduce drawing resistance, reduce the occurrence of drawing breakage, and improve product quality and production efficiency.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 In this embodiment, a metal wire drawing machine is used to increase the heating time of the metal wire;

[0027] Specifically, it includes a base plate 1, a feeding roller 2, and a take-up roller 3; the feeding roller 2 and the take-up roller 3 are respectively installed on the left and right sides of the upper surface of the base plate 1, and a linear guide rail 4 is provided on the upper surface of the base plate 1. A heating cylinder 5 is connected to the linear guide rail 4 for driving the heating cylinder 5 to move left and right.

[0028] In actual setup, the pay-off roller 2 is used to place the raw metal wire to be drawn, and the take-up roller 3 is used to take up the drawn metal wire. The heating cylinder 5 can be driven to move left and right through the linear guide rail 4, so that the position of the heating cylinder 5 can be adjusted according to actual production needs.

[0029] Mounting rings 6 are installed on both the left and right sides of the inner wall of the heating cylinder 5, and a heating wire 7 is provided between the opposite sides of the two mounting rings 6.

[0030] A support frame 8 is installed on the base plate 1. A mounting plate 9 is vertically installed inside the support frame 8. A mounting groove 901 is opened horizontally inside the mounting plate 9. Two first guide wheels 902 are rotatably connected inside the mounting groove 901. Two horizontal plates 10 are arranged parallel to each other on the right side of the mounting plate 9. A second guide wheel 11 is provided on the opposite side of each of the two horizontal plates 10. A diagonal bar 12 is integrally formed at the right end of each of the two horizontal plates 10.

[0031] In actual setup, the heating wire 7 is spirally distributed and sleeved on the outside of the two mounting plates 9. When the heating wire 7 is energized, it can generate heat to heat the metal wire entering the heating cylinder 5.

[0032] The two diagonal bars 12, away from the horizontal plate 10, are provided with the same guide tube 13.

[0033] In actual setup, the second guide wheels 11 on the upper and lower sides are staggered left and right. This staggered distribution design allows the metal wire to form a certain bending path when passing through, increasing the residence time and heating path of the metal wire in the heating cylinder 5.

[0034] In actual use, firstly, the metal wire raw material to be drawn is placed on the wire feeding roller 2. One end of the metal wire passes through the first guide wheel 902, the second guide wheel 11, and the wire tube 13 in sequence, enters the heating cylinder 5, then passes through the wire guiding mold 16, and is finally fixed on the take-up roller 3.

[0035] Start the take-up roller 3. The take-up roller 3 rotates and drives the metal wire to move. During the movement, the metal wire passes through the first guide wheel 902 and the second guide wheel 11 in sequence. Since the second guide wheels 11 on the upper and lower sides are staggered, the metal wire forms a curved path when passing through the second guide wheel 11, which increases the residence time in the heating cylinder 5.

[0036] At the same time, the heating wire 7 is activated. After the heating wire 7 is powered on, it generates heat to heat the metal wire in the heating cylinder 5, softening the surface of the metal wire. Since the heating wire 7 is spirally distributed and sleeved on the outside of the two mounting plates 9, it can heat the metal wire evenly.

[0037] After being heated and softened, the metal wire passes through the wire guide die 16 and is pulled under the tension of the take-up roller 3, and is finally wound up by the take-up roller 3.

[0038] In addition, a support wheel 14 is installed on the lower inclined bar 12 to support the metal wire, prevent the metal wire from sagging due to gravity during the transmission process, ensure that the metal wire can maintain a stable transmission state, and avoid affecting the pulling effect.

[0039] Furthermore, a support base 14 is installed on the upper surface of the base plate 1. A connecting groove 15 is vertically opened inside the support base 14. A wire guide mold 16 is detachably installed inside the connecting groove 15. A protrusion is integrally formed on both the front and rear sides of the wire guide mold 16. Corresponding to the protrusion, a sliding groove is opened on both the front and rear sides of the inner wall of the connecting groove 15.

[0040] In actual use, the wire guide mold 16 is detachably installed in the connecting groove 15 of the support base 14 through the cooperation of the convex strip with the sliding groove on the inner wall of the connecting groove 15. This makes it easy to replace the wire guide mold 16 according to different metal wire specifications and drawing requirements, thus improving the applicability and flexibility of the device.

[0041] In actual use, the drive mechanism of the linear guide 4 is activated, and the heating cylinder 5 slides to the right along the guide until it is completely moved out of the outer side of the mounting plate 10. At this time, the second guide wheels 11 on the upper and lower sides are fully exposed, the shuttle path of the metal wire is released, and after the metal wire is led out from the wire feeding roller 2, it first passes through the first guide wheel 902 of the mounting plate 9 and then enters the space between the two mounting plates 10.

[0042] Because the upper and lower second guide wheels 11 are misaligned, the metal wire needs to pass around the inner side of the upper and lower second guide wheels 11 in an "S" shape to increase the length of the heating path. After passing through, the heating cylinder 5 is driven to move to the left in the opposite direction so that it re-encloses the right end of the mounting plate 10. The heating wire 7 is reset to the outside of the mounting plate 9 to form a heating space.

[0043] In actual setup, the heating mechanism of a traditional drawing machine is fixed, and the metal wire needs to pass through the guide wheel from the narrow heating chamber, which is difficult to operate and prone to jamming. This design exposes the area of ​​the second guide wheel 11 by moving the heating cylinder 5, so that the operator can directly thread the metal wire from the outside, avoiding the safety hazard of putting hands into the heating chamber, and improving the threading efficiency.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
