Technical Field
[0001] This utility model relates to the field of wire drawing equipment technology, specifically a quick mold changing device for multi-head wire drawing machines. Background Technology
[0002] Multi-head wire drawing machines are essential equipment in the metal wire processing industry. They use multiple sets of dies to sequentially stretch and deform metal billets, gradually reducing the wire diameter to the target size (typically requiring tolerance control within ±0.01mm). In this process, the die, as the core component directly in contact with the wire, directly affects the consistency of the finished wire diameter due to the accuracy of its internal dimensions and the stability of its installation. Therefore, rapid and accurate die replacement is a crucial step in ensuring production efficiency and product quality.
[0003] Currently, the industry commonly uses an interference fit combined with bolt fastening structure to fix the die head. Specifically, the die head is inserted into the die groove of the die holder through an interference fit, and a rubber sealing gasket is placed between the outer end face of the die head and the die groove to achieve a buffering and sealing function. Finally, the die head is locked to the die holder by circumferentially distributed bolts. However, this structure has the following drawbacks in practical applications:
[0004] When changing the mold head, all fastening bolts must be removed one by one. Then, the friction generated by the interference fit between the mold head and the mold groove and the damping effect of the rubber sealing gasket must be overcome. The mold heads are pulled out one by one by manual force. Since each mold base is usually equipped with 5-10 mold heads, the operator needs to repeat the action of pulling out the mold heads many times, which makes a single replacement take tens of minutes, which is physically demanding and time-consuming.

[0028] 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.
[0029] Example: This utility model provides a technical solution for a quick die-changing device for a multi-head wire drawing machine, such as... Figures 1-6 As shown, it includes: a storage unit 100, which includes a storage cabinet 101, a placement rack 104 fixed to the top of the storage cabinet 101, a mounting shell 300 mounted on the placement rack 104, an operating handle 301 fixed to the top of the mounting shell 300, a clamping unit 500 assembled and extending into the mounting shell 300, and a guide unit 600 fixed and extending to the bottom of the mounting shell 300.
[0030] In the above scheme:
[0031] The storage cabinet 101 allows for the storage and placement of the mold heads, making it more convenient and faster for personnel to replace them.
[0032] The device achieves split-type operation by installing the housing 300 and its own operating handle 301, which not only meets the daily operation needs of changing the mold head, but also allows the mold head to be classified and stored before and after the change, ensuring the convenience of personnel during operation.
[0033] The clamping unit 500 is placed on top of the storage cabinet 101 by the placement rack 104, which facilitates the unified transfer of the device by personnel.
[0034] Through the cooperation between the clamping unit 500 and the guiding unit 600, the device can quickly dock with the mold unit 400, and can simultaneously clamp multiple sets of mold heads on the mold unit 400, and automatically separate the mold head from the mold base. This allows the device to complete the replacement of multiple mold heads at once, improving work efficiency.
[0035] The mold unit 400 includes a mold base 402 and a docking interface 4022 disposed on the top of the mold base 402 and docking with the guide unit 600;
[0036] The clamping unit 500 includes two sets of guide ports 3001 located at the bottom of the mounting housing 300 and staggered, a guide block 502 that slides in the guide port 3001 and extends into the mounting housing 300, a clamping plate 501 fixed to the bottom of the guide block 502, and a toothed plate 505 fixed to the top of the guide block 502 and meshing with the ring gear 507.
[0037] The guide unit 600, the support frame 601 which slides on one side of the mounting housing 300 and extends downward, the docking block 603 which is fixed to the bottom of the support frame 601 and docks with the docking interface 4022, and the electric telescopic cylinder 602 which is fixed to the top of the support frame 601 and connected to the bottom of the mounting housing 300.
[0038] During daily operations:
[0039] Personnel operate the device by holding it through the handle 301 on the top of the mounting shell 300 and inserting it into the interface 4022 through the docking block 603, thus achieving positioning and docking between the device clamping unit 500 and the mold base 402. Then, the personnel can start the drive component to drive the drive shaft 506, and use the ring gear 507 on the drive shaft 506 to drive the toothed plate 505, causing the bottom guide block 502 to drive the clamping plate 501 to move in the opposite direction. The clamping plate 501 completes the clamping operation of the mold head. Then, the electric telescopic cylinder 602 is activated to push the mounting shell 300 in the opposite direction, at which time the clamped mold head will be lifted synchronously, completing the separation between the mold bases. After the former mold head is placed, the mold head in the storage cabinet 101 can be clamped and extracted according to the above steps, and then docked with the mold base. The extracted mold head is placed in the mold base to complete the replacement. After the operation is completed, the clamping unit 500 synchronous guide unit 600 can be placed on the placement rack 104.
[0040] Furthermore, a support unit 200 is fixedly installed at the bottom of the storage cabinet 101. The support unit 200 includes a base 201. The base 201 is fixedly installed at the bottom of the storage cabinet 101. A traveling wheel 202 is fixedly installed at the four corners of the bottom of the base 201. A storage box 203 is placed on the top of the base 201.
[0041] Specifically, during the operation, personnel can move the device in real time according to the actual working position using the walking wheels 202 at the bottom of the base 201, ensuring flexibility and convenience during the operation.
[0042] During the replacement process, the removed mold head can be placed in the storage box 203, which is equipped with a mesh plate to separate the processing fluid on the mold head, ready for subsequent cleaning.
[0043] Furthermore, a mold groove 4021 is provided on the top of the mold base 402, and a mold head 401 is embedded in the mold groove 4021.
[0044] Specifically, during operation, the mold head 401 will be embedded into the corresponding mold groove 4021. When placing it, the mold head 401 is pressed vertically into the mold groove 4021, ensuring that there is no tilt.
[0045] To enable the device to better facilitate personnel in replacing the mold head 401, the storage cabinet 101 has an extended storage drawer 102 that slides inside, and a mold head mounting plate 103 for placing the mold head 401 is embedded inside the storage drawer 102.
[0046] Specifically, the die head mounting plate 103 is embedded with a new wire drawing specification die head 401, and the spacing between them is the same as the spacing between the die base 402, so that it is more convenient for personnel to retrieve them; and the different specifications of die heads 401 are placed in layers through the storage drawer 102, so that when personnel need to replace them, they only need to find the corresponding specification layer.
[0047] Furthermore, a servo motor 504 is fixedly installed inside the mounting housing 300. A rotating shaft 510 is connected to the output end of the servo motor 504. A first bevel gear 508 is fixedly installed on the rotating shaft 501. A second bevel gear 509 is fixedly installed on the top of the drive shaft 506, and the second bevel gear 509 meshes with the first bevel gear 508. Built-in rubber pads 503 are fixedly installed on the inner sides of the clamping plate 501.
[0048] Specifically, during the extraction process, the servo motor 504 is activated, driving the rotating shaft 510 to rotate. The rotating shaft 510 then drives the second bevel gear 509 via the first bevel gear 508 on its own, thereby driving the drive shaft 506 to rotate. At that time, the ring gear 507 on the drive shaft 506 drives the toothed plate 505, causing the bottom guide block 502 to drive the clamping plate 501 to move in the opposite direction. The clamping plate 501 completes the clamping operation of the mold head, and during the clamping period, the clamping plate 501 uses the built-in rubber pad 503 to increase the stability during clamping.
[0049] Furthermore, the guide port 3001 and the guide block 502 are slidably connected by guide rail one; the support frame 601 and the mounting shell 300 are slidably connected by guide rail two.
[0050] The purpose of sliding connection between guide port 3001 and guide block 502 via guide rail is to ensure that clamping plate 501 moves more smoothly in linear motion.
[0051] The support frame 601 and the mounting shell 300 are slidably connected by the guide rail 2 in order to cooperate with the electric telescopic cylinder 602 to perform reverse pushing operation on the mounting shell 300, so as to ensure that there is no interference between the support frame 601 and the mounting shell 300 during reverse pushing.
[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
