Description

Technical Field

[0001] This utility model relates to the field of wire drawing die technology, specifically a wire drawing die that is easy to repair and replace. Background Technology

[0002] Wire drawing dies are industrial tools that apply pressure to metal wires through die holes to compress their cross-sectional area. Their core structure includes an inlet lubrication zone, a working zone, a sizing zone, and an outlet zone. They have been industrialized in high-speed rail cables, aircraft tires, and other applications. However, the inside of wire drawing dies may wear out after long-term use, and a type of wire drawing die that is easy to maintain and replace is needed to meet the requirements of wires of different diameters.

[0003] The prior art patent document with publication number CN222957206U provides a wire drawing die that is easy to repair and replace. It includes a support platform, a support frame fixedly installed at the top of the support platform, a wire drawing die body disposed inside the support frame, and a support column fixedly installed at the lower inner part of the support frame. Through the coordinated use of components such as bolts, a lower column, an upper support plate, a plug rod, a connecting block, a first spring, a lower support plate, and a connecting plate, the wire drawing die body can be disassembled, repaired, and replaced. The disassembly and assembly of the wire drawing die body is convenient and quick, significantly improving work efficiency and reducing the impact on the progress of wire drawing processing. When the workpiece box is pulled out by sliding a slider on a locking column for replacement of the wire drawing die body, the second spring facilitates the automatic return of the workpiece box to the movable slot. The structure is ingenious and convenient to use.

[0004] Although the device has many beneficial effects, it still has the following problems: During the use of the device, it is necessary to loosen bolts for disassembly and assembly, which is not fast enough and not convenient to use; secondly, it is not convenient to replenish the lubricant at any time during the use of the device. After the lubricant coated on the material is consumed during the wire drawing process, it is easy to wear and break, which affects the finished product. Improvement is needed. In view of this, we propose a wire drawing die that is easy to maintain and replace. Utility Model Content

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural diagram of an embodiment of a wire drawing die that is easy to repair and replace, including:

[0035] Please see Figures 1-5 This embodiment of a wire drawing die that is easy to maintain and replace includes a fixed frame 1. A lower support 2 is welded to the bottom of the inner cavity of the fixed frame 1. An upper support 3 is snapped onto the top of the lower support 2. A fixing component 4 is slidably connected to the side wall of the lower support 2. The fixing component 4 includes a pull rod 401, which is designed for easy one-handed operation to control the snapping on both sides, making it more convenient to use. A first locking block 402 is welded to one end of the top of the pull rod 401. A connecting plate 403 is slidably connected to the other end of the pull rod 401. A sliding groove 404 is provided on the side wall of the connecting plate 403. The sliding groove 404 is designed to slide with the connecting plate 403 to prevent the connecting plate 403 from being restricted in its rotation. A second locking block 405 is hinged to the other end of the connecting plate 403. Multiple first springs 406 are welded to the side wall of 405. The first springs 406 are used to drive the second locking block 405 to return to the locking groove 409 when no force is applied. Positioning grooves 407 are opened on both sides of the top of the lower support 2. Positioning plates 408 are welded to both sides of the bottom of the upper support 3. Positioning grooves 407 are used to engage with positioning plates 408 to initially position the lower support 2 and the upper support 3. The side walls of the two positioning plates 408 are opened with locking grooves 409. The locking grooves 409 are used to engage with the first locking block 402 and the second locking block 405 to improve the stability of the splicing of the lower support 2 and the upper support 3. A wire drawing die 5 is locked to the inner circumference of the lower support 2. The wire drawing die 5 is used for wire drawing and shaping. A lubrication component 6 is welded to the side wall of the lower support 2.

[0036] It is worth noting that, specifically, for immediate lubrication of the drawing material, the lubrication component 6 includes a storage tank 601 for storing lubricant. A high-pressure pump 602 is connected to the side flange of the storage tank 601. The high-pressure pump 602 is used to pump lubricant at any time, facilitating immediate lubrication during the drawing process. It has a certain pressure to better spray the lubricant onto the surface of the drawing material. A feed pipe 603 is connected to the output flange of the high-pressure pump 602. A limit groove 604 is opened on one side of the inner circumference of the lower support 2. A limit block 605 is welded to the outer circumference of the drawing die 5. The limit groove 604 is used to engage the limit block 605 to facilitate connection with the lubricant delivery channel. Multiple pipes 606 are opened inside the drawing die 5 to cooperate with the feed pipe 603 to deliver lubricant. Each of the multiple pipes 606 has a nozzle 607 at the other end. The nozzle 607 is used to spray the lubricant to the outside of the drawing material for convenient lubrication and to avoid wear. The high-pressure pump 602 is electrically connected to an external power source.

[0037] Next, to facilitate use by staff, a handle 410 is welded to the other end of the pull rod 401. The outer circumference of the handle 410 is integrally provided with multiple annular protrusions. The pull rod 401 is slidably connected to the side wall of the fixed frame 1. By providing a handle 410 with multiple annular protrusions, the friction is increased, making it easier for staff to pull the pull rod 401.

[0038] Meanwhile, to prevent the lower support 2 and the upper support 3 from loosening, specifically, the dimensions and positions of the first locking block 402 and the second locking block 405 are matched with the dimensions and positions of the slot 409, and the dimensions and positions of the positioning slot 407 are matched with the dimensions and positions of the positioning plate 408. By using the first locking block 402 and the second locking block 405 that match the dimensions and positions of the slot 409, the lower support 2 and the upper support 3 are more securely connected, preventing loosening.

[0039] Furthermore, to facilitate the delivery of lubricant, specifically, the bottom of the high-pressure pump 602 is threadedly connected to a support plate 608 located on the side wall of the lower support 2, and the limiting block 605 has flow channels that are respectively connected to the conveying pipe 603 and the pipeline 606. The support plate 608 makes the high-pressure pump 602 more stable during operation and prevents it from falling. The flow channels that are respectively connected to the conveying pipe 603 and the pipeline 606 facilitate the smooth delivery of lubricant to the nozzle 607.

[0040] It is worth noting that, in order to facilitate the disassembly and assembly of the wire drawing die 5, specifically, multiple moving rods 7 are welded to the top of the upper support 3, a pull plate 8 is welded to the top of the moving rod 7, and multiple second springs 9 are welded to the top of the upper support 3 and sleeved on the outer circumference of the moving rod 7. By manually pulling the pull plate 8, the upper support 3 is moved upward, which facilitates the disassembly and assembly of the wire drawing die 5 and makes it easy to repair and replace. The rebound force of the second spring 9 makes it easy for the upper support 3 to move downward and reset.

[0041] Finally, to prevent the wire drawing die 5 from slipping during wire drawing, specifically, the size of the inner cavity at the top of the lower support 2 matches the size of the wire drawing die 5, and the size of the inner cavity at the bottom of the upper support 3 matches the size of the wire drawing die 5. Limiting rings 10 are welded to both ends of the inner circumference of the lower support 2 and the upper support 3. The inner cavities at the top of the lower support 2 and the bottom of the upper support 3, which match the size of the wire drawing die 5, make the installation of the wire drawing die 5 more stable and prevent the wire drawing die 5 from slipping and causing wire breakage. The limiting rings 10 prevent the wire drawing die 5 from slipping out due to force during wire drawing.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] High-pressure pump 602: ALPB100.

[0045] Combination Figures 1-5 The following is a specific usage process for a wire drawing die that is easy to repair and replace according to this embodiment:

[0046] 1. When this device is needed to facilitate the maintenance and replacement of wire drawing dies, pull the handle 410 to move the pull rod 401, causing the first locking block 402 to disengage from one side of the locking groove 409, causing the connecting plate 403 to rotate and causing the second locking block 405 to move and disengage from the other side of the locking groove 409. Pull the pull plate 8 to move the upper support 3 upward, and remove the wire drawing die 5 for maintenance or replacement. After the innovative installation, release the pull plate 8, and the rebound force of the second spring 9 will cause the upper support 3 to move downward, causing the positioning plate 408 to insert into the positioning groove 407 to splice the lower support 2. Release the handle 410, and the rebound force of the first spring 406 will cause the first locking block 402 and the second locking block 405 to respectively engage with the two side locking grooves 409.

[0047] 2: When drawing wire, start the high-pressure pump 602 to pump the lubricant in the storage tank 601 along the conveying pipe 603. The lubricant flows in from the flow channel inside the limit block 605 and is then evenly sprayed out from multiple nozzles 607 through multiple pipes 606 inside the wire drawing die 5 to the outside of the wire drawing material for lubrication at any time.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
