Description

Technical Field

[0001] This utility model relates to the field of steel cord production technology, and more specifically to a mold string hanger for quick mold changing in water tanks. Background Technology

[0002] The wet drawing process for steel wire products typically requires multiple consecutive drawing passes. The equipment is generally equipped with 23 to 25 drawing dies of progressively decreasing size, which are immersed in lubricating fluid during operation. During the drawing process, the steel wire passes through the dies arranged in descending order of size, gradually reducing its diameter to the target diameter.

[0003] In the above-mentioned continuous wet drawing operation of steel wire, when changing specifications, it is usually necessary to cut the steel wire passing through the die box, then pull it out from each drawing die in turn, and repeat the die-threading operation.

[0004] During the initial threading process, the wires must be threaded sequentially from the largest die hole to the smallest die hole according to the die chain (die string) sequence specified in the process. During this process, the wire ends must be manually and repeatedly rubbed (commonly known as "sharpening") to reduce their diameter and facilitate passage through the die holes. This process is then repeated for the second, third, and all subsequent die holes. Finally, the wires are wound around the traction wheel, and the equipment's traction force is used to gradually pull each section of wire into its corresponding die box. Only after installation is complete can the equipment be started.

[0005] As mentioned above, the molding process is cumbersome and repetitive, and all operations must be repeated when changing production specifications, which seriously affects production efficiency and flexibility.

[0006] In fact, by using the equipment's reversing function to unmold the steel wire from the drawing tower's wheel system, the entire wire can be removed from the die chain without breaking it, thus avoiding repeated threading and significantly simplifying the operation. However, because the unmolded wire passes through multiple die holes and is quite long, there is currently a lack of dedicated storage and temporary storage devices. If placed directly on the ground, it is prone to tangling, knotting, surface scratches, and chaotic on-site management, increasing operational difficulty and quality risks. Therefore, although the unmolding method is theoretically more convenient, it is difficult to promote and apply in actual production.

[0007] In summary, the existing wet drawing machine die-changing operation still mainly relies on shearing and re-threading. The fundamental bottleneck lies in the lack of steel wire suspension, positioning, and management methods to match the die-off operation, which prevents the more efficient operation method from being put into practical application.

Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein:

[0028] Figure 2 This is a front view of the mold string hanger for quick mold changing of the water tank shown in this utility model;

[0030] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0031] Combination Figure 1 and Figure 2 As shown, this utility model proposes a mold string hanger for quick mold changing of water tanks, including a base plate 10, multiple uprights 20, a first wire guide wheel 30, a second wire guide wheel 40, and a mold limiting seat 50.

[0032] The base plate 10 is provided with multiple insertion holes. The base plate 10 is made of stainless steel and is used to support multiple uprights 20 to keep them perpendicular to the base plate 10, so that the multiple uprights 20 connected to the base plate 10 are parallel to each other and will not tip over under load.

[0033] Furthermore, multiple uprights 20 are inserted into the insertion holes on the base plate 10. Each upright 20 is provided with multiple limiting holes 21 arranged along its length. The first wire guide wheel 30 is connected to the limiting hole 21 located at the top of the upright 20, the second wire guide wheel 40 is connected to the limiting hole 21 located at the bottom of the upright 20, and the mold limiting seat 50 is connected to the limiting hole 21 located in the middle of the upright 20.

[0034] Thus, on each upright post 20, the first thread guide wheel 30, the mold limiting seat 50, and the second thread guide wheel 40 are distributed in the upper, middle, and lower positions respectively.

[0035] The mold limiting seat 50 is used to accommodate one of the molds 200 on the mold string, and the inlet section 100 of the mold 200 bypasses the first wire guide wheel 30, and the outlet section 300 of the mold 200 bypasses the second wire guide wheel 40, so that the mold string passes through all the first wire guide wheels 30, the mold limiting seat 50 and the second wire guide wheel 40 in a serpentine manner.

[0036] Specifically, in combination Figure 3 As shown, it should be understood that a die string typically includes multiple dies 200, each die 200 having a certain length of steel wire of different diameters. Therefore, each die 200 includes a wire inlet segment 100 and a wire outlet segment 300. To arrange the die string in an orderly manner, each die 200 is placed on a die limiting seat 50, with the corresponding wire inlet segment 100 passing around the first wire guide wheel 30 and the wire outlet segment 300 passing around the second wire guide wheel 40, forming a... Figure 3 The winding state is shown.

[0037] In this way, placing the mold strings avoids the clutter caused by traditional placement methods, and therefore people tend to choose to remove the mold strings to replace them, saving time.

[0038] In an alternative embodiment, on one side of each upright 20, the spacing between the first guide roller 30, the mold limiting seat 50, and the second guide roller 40 is adjusted according to the spacing between adjacent molds 200 on the mold string.

[0039] Specifically, since the spacing between each mold 200 is different, in order to keep the steel wires between the molds 200 as taut as possible, the positions of the first wire guide wheel 30, the mold limit seat 50 and the second wire guide wheel 40 on each upright 20 can be flexibly adjusted so that the steel wires of the entire mold string are placed in an orderly manner.

[0040] Furthermore, the surfaces of the first guide wheel 30 and the second guide wheel 40 are provided with wire grooves, the width and depth of which are greater than the diameter of the steel wire.

[0041] In this way, when the wire passes over the groove on the surface of the first guide wheel 30 and the second guide wheel 40, the wire can be prevented from falling off the surface of the first guide wheel 30 or the second guide wheel 40.

[0042] In the above embodiment, the height of the upright 20 is 1.2m to 1.5m, and the distance between adjacent limiting holes 21 on the upright 20 is 10cm. The distance between adjacent uprights 20 is 15 to 20cm.

[0043] Thus, by setting up densely spaced limiting holes 21, users can flexibly adjust the positions of each first wire guide wheel 30, second wire guide wheel 40, and mold limiting seat 50 to adapt to different types of mold strings.

[0044] In an optional embodiment, the mold limiting seat 50 is provided with a positioning groove 51 and a wire guide groove 52, and the positioning groove 51 is configured as an open groove with openings at the top and sides.

[0045] In this way, the mold 200 can be placed into the positioning groove 51 from above or the side, and the wire passage groove 52 is located at the bottom of the positioning groove 51, so that the wire exit section 300 of the mold 200 can pass through the wire passage groove 52.

[0046] In the above embodiments, a pin is provided on one side of the first thread guide wheel 30, the mold limiting seat 50, and the second thread guide wheel 40, and the pin can be inserted into the limiting hole 21.

[0047] Furthermore, the surface of the pin is provided with an axial positioning structure, so that after being inserted into the limiting hole 21, it is axially fixed with the limiting hole 21.

[0048] Optionally, the axial positioning structure can be an elastic ball or an elastic retaining ring disposed on the surface of the pin, so that after the pin is inserted into the limiting hole 21, it can be axially positioned by the positioning groove in the limiting hole 21, thus preventing the pin from coming out of the limiting hole 21.

[0049] In a preferred embodiment, the diameters of the first guide roller 30 and the second guide roller 40 are equal to the outer diameter of the mold 200. This allows for a compact structure for each upright 20, with smaller spacing between them, which facilitates the formation of multiple linearly arranged uprights 20 on the base plate 10. The multiple insertion holes on the base plate 10 are also arranged in a linear distribution.

[0050] In conjunction with the above embodiments, the mold string hanger proposed by this utility model can hang mold strings disassembled from the wire drawing roller. Each mold on the mold string is supported by a mold limiting seat. The steel wire on the mold string is serpentinely wound between multiple uprights. The number of uprights can be selected according to the number of molds in the mold string. Moreover, the distance between the mold limiting seat and the first wire guide roller and the second wire guide roller can be flexibly adjusted by the distance between the molds to meet the hanging requirements of different mold strings. This allows people to choose to remove the mold and handle the water tank mold replacement without causing chaos on site.

[0051] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
