Description

Technical Field

[0001] This utility model relates to the field of metallurgical casting, specifically to a wire feeding device for grain refiner. Background Technology

[0002] The origins of the grain refiner industry are inextricably linked to the modernization of the aluminum industry. Long-standing defects in aluminum alloy ingot production, such as cracks (caused by solidification shrinkage stress), compositional segregation (uneven distribution of alloying elements), and feather-like grains (mechanical property degradation caused by coarse columnar crystal structures), severely restricted product quality and production efficiency. To overcome this technical bottleneck, the metallurgical community proposed controlling the metal solidification process by adding heterogeneous nucleating agents, leading to the development of the AlTiB series of grain refiners (aluminum-titanium-boron master alloys). By introducing TiB2 particles into the melt as a nucleation substrate, they significantly refine grain size, marking a milestone in the innovation of aluminum alloy casting processes.

[0003] Grain refiner products are typically processed into φ9.5mm wires, which are then coiled into hollow coils using a winding machine. During use, they are added online to the runner before the ingot cools. The purpose of making the grain refiner into wire coils is to facilitate use by a wire feeder. However, after the grain refiner wire is made into hollow coils, it needs to be tied with slings and transported individually, resulting in low feeding efficiency and an unstable feeding process. Summary of the Invention

[0004] To address the issues of low feeding efficiency and instability in the single-reel hoisting of grain refiner wire after it has been made into hollow reels, which requires slings for binding, this invention proposes a grain refiner wire feeding device. With the continuous traction of the front wire feeder, the wire turntable rotates freely according to the wire tension, realizing wire feeding. The feeding process is stable, and by setting two trays, it is convenient to switch between them and can also realize parallel working mode, improving feeding efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A grain refiner wire feeding device includes a base and two circular tubes symmetrically arranged above the base. A feeding component is rotatably arranged on the top of the circular tubes. The feeding component includes a turntable and a support tube. A connecting component is arranged between the turntable and the circular tubes. The support tube is vertically arranged at the center of the top of the turntable. The top of the turntable is also provided with a wire feeding assembly, which includes a support member and a guide member vertically arranged above the center of the support member. The support member includes an inner ring and an outer ring arranged outside the inner ring, and a crossbar is arranged between the inner ring and the outer ring. The guide member includes a vertical rod and a disk. There are several vertical rods arranged in a circular array around the support tube, and the top of the vertical rods are connected to the disk. It also includes a tray for placing the wire reel, the tray being placed on a support and having a through hole in the center for a guide to pass through. With the continuous traction of the front wire feeder, the wire reel rotates freely according to the wire tension, realizing wire feeding. The feeding process is stable, and by setting two trays, switching between them is convenient, and a parallel working mode can be achieved, improving feeding efficiency.

[0006] Furthermore, the inner and outer rings are concentrically arranged, and the crossbars are arranged in a circular array around the inner ring. The crossbars between the inner and outer rings ensure even load distribution, preventing localized deformation of the pallet.

[0007] Furthermore, the support tube is a hollow tube, and the top of the support tube is set with a tapered portion. The tapered portion is used to guide the wire reel for centering and positioning.

[0008] Furthermore, the top of the vertical rod is bent inward to form a bend, and the bends are arranged in a circumferential array around the tapered portion. The bends cooperate with the tapered portion to prevent the wire reel from shifting.

[0009] Furthermore, an n-shaped hook is provided on the top of the disk.

[0010] Furthermore, the connecting assembly includes a rotating shaft, the top end of which is fixedly connected to a turntable, and a seated bearing is provided at the connection between the rotating shaft and the round tube. The bottom end of the rotating shaft is inserted into the inner ring of the seated bearing. A fixed seat is provided at the top of the round tube, and the fixed seat and the seated bearing are connected by bolts and nuts.

[0011] Furthermore, a reinforcing rod is provided between the two circular tubes.

[0012] Furthermore, the base has two sets of mounting holes symmetrically arranged on its left and right sides, with four mounting holes in each set, and an anchor bolt inserted into each mounting hole. The base is fixed to the ground by eight anchor bolts.

[0013] The beneficial effects of this utility model through the above technical solution are as follows: This utility model provides a wire feeding device for grain refiner. A wire reel and tray are hoisted onto a turntable via a hook. As the hollow wire reel falls, its central hole is guided to center by the tapered part of the support tube, while the bent part forms an annular limiting zone to prevent the wire reel from shifting. After hoisting, the wire reel is placed horizontally on the turntable. The weight of the wire reel is evenly transmitted to the inner and outer rings through a crossbar, preventing localized deformation of the tray. When the wire feeder pulls the grain refiner wire, the wire turntable rotates freely with the wire tension, reducing unloading resistance. Furthermore, with the continuous traction of the wire feeder, the wire reel is unloaded and fed, ensuring stable operation during the feeding process. Additionally, by setting up two trays, on the one hand, while tray A is unloading, tray B is pre-loaded with a new wire reel for backup; once tray A is exhausted, the system quickly switches to tray B. On the other hand, both trays are simultaneously connected to the wire feeder, providing synchronous feeding to the casting wire flow channel. This parallel working mode doubles the processing capacity per unit time, improving feeding efficiency. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6As shown, this embodiment provides a grain refiner wire feeding device, including a base 1 and two circular tubes 2 symmetrically arranged above the base 1. A feeding assembly is rotatably arranged on the top of the circular tubes 2. The feeding assembly includes a turntable 3 and a support tube 4. A connecting assembly is provided between the turntable 3 and the circular tubes 2. The support tube 4 is vertically arranged at the center of the top of the turntable 3. A wire feeding assembly is also provided on the top of the turntable 3. The wire feeding assembly includes a support member and a guide member vertically arranged above the center of the support member. The support member includes an inner ring 5 and an outer ring 6 arranged outside the inner ring 5. A crossbar 7 is arranged between the inner ring 5 and the outer ring 6. The guide member includes a vertical rod 8 and a disc 9. Several vertical rods 8 are arranged in a circumferential array around the support tube 4. The top of the vertical rods 8 are connected to the disc 9. It also includes a tray 11 for placing wire reels 10. The tray 11 is placed on the support member and has a through hole in the center for the guide member to pass through. The wire reel 10 is placed horizontally on the tray 11 for easy replacement and to prevent it from falling apart. The tray 11 has a through hole in the center, through which the guide rod 8 passes and is placed on the support rod 7. The diameter of the through hole is adapted to the inner diameter of the wire reel 10.

[0017] This utility model provides a wire feeding device for grain refiners. The wire reel 10 and tray 11 are hoisted together onto a turntable 3. When the hollow wire reel 10 falls, its central hole is guided to center by the tapered part 12 of the support tube 4, while the bent part 13 forms an annular limiting zone to prevent the wire reel 10 from shifting. After being hoisted into place, the wire reel 10 is fed out by the continuous traction of the front wire feeder. Furthermore, by setting two trays 11, on the one hand, when tray 11A is feeding out, tray 11B is pre-loaded with a new wire reel 10 for backup; when tray 11A is exhausted, it is quickly switched to tray 11B. On the other hand, both trays 11 are simultaneously connected to the wire feeder, synchronously feeding the casting wire flow channel. This parallel working mode doubles the processing capacity per unit time, improving feeding efficiency.

[0018] Please refer to this again. Figure 4 The inner ring 5 and the outer ring 6 are concentrically arranged, and the crossbars 7 are arranged in a circular array around the inner ring 5. The inner ring 5, the outer ring 6 and the crossbars 7 together constitute the load-bearing platform of the tray 11. Specifically, the wire reel 10 presses down on the tray 11 due to its own weight, and the load is evenly distributed by the crossbars 7 between the inner ring 5 and the outer ring 6 to avoid local deformation of the tray 11.

[0019] Please refer to this again. Figure 3 The support tube 4 is a hollow tube, and its top is set as a tapered part 12. The support tube 4 is vertically fixed to the center of the turntable 3, and its top is designed as a tapered part 12 to guide the wire reel 10 to be centered and positioned.

[0020] In this embodiment, the top of the vertical rod 8 is bent inward to form a bent portion 13, and the bent portions 13 are distributed in a circumferential array around the conical portion 12. The bent portions 13 cooperate with the conical portion 12. Specifically, the bent portions 13 at the top of the vertical rod 8 circumferentially surround the conical portion 12, forming a radial constraint to prevent the wire reel 10 from shifting and eliminate the risk of reel scattering caused by shifting.

[0021] The disc 9 is equipped with an n-shaped hook 14 on its top. The hook 14 on the top of the disc 9 facilitates the overhead crane to lift the wire reel 10 onto the turntable 3, enabling rapid material change.

[0022] Please refer to this again. Figure 5 The connecting assembly includes a rotating shaft 15, the top end of which is fixedly connected to the turntable 3. A bearing 16 with a seat is provided at the connection between the rotating shaft 15 and the circular tube 2, and the bottom end of the rotating shaft 15 is inserted into the inner ring of the bearing 16. A fixed seat 17 is provided at the top of the circular tube 2, and the fixed seat 17 and the bearing 16 with a seat are connected by bolts and nuts. The turntable 3 is rotatably connected to the circular tube 2 through the connecting assembly. When the wire feeder pulls the grain refiner wire, the turntable 3 rotates freely with the wire tension, reducing the wire feeding resistance.

[0023] In this embodiment, a reinforcing rod 18 is provided between the two circular tubes 2. The two circular tubes 2 are symmetrically welded to the base 1 and connected by the transverse reinforcing rod 18 to form a rigid frame, which reduces the impact of vibration on the feeding process and adapts to the feeding conditions of high-speed feeding lines.

[0024] It is worth mentioning that the base 1 has two sets of mounting holes symmetrically arranged on its left and right sides, with four mounting holes in each set, and each mounting hole is fitted with an anchor bolt 19. The base 1 is fixed to the ground by eight anchor bolts 19 to ensure the device's resistance to overturning.

[0025] The working principle of this utility model is as follows: The wire reel 10 and pallet 11 are hoisted onto the turntable 3 as a whole using hook 14. When the hollow wire reel 10 falls, its central hole is guided to center by the tapered part 12 of the support tube 4, while the bent part 13 of the vertical rod 8 forms an annular limiting area to prevent the wire reel 10 from shifting. After being hoisted into place, the wire reel 10 is placed horizontally on the turntable 3. The weight of the wire reel 10 is evenly transmitted to the inner ring 5 and outer ring 6 through the crossbar 7 to avoid local deformation of the pallet 11. When the wire feeder pulls the grain refiner wire, the wire turntable 3 rotates freely with the wire tension to reduce the resistance to wire feeding. Furthermore, with the continuous traction of the wire feeder in front, the wire reel 10 is fed into the turntable.

[0026] More importantly, by setting up two trays 11, on the one hand, when tray 11A is in the line feeding operation, tray 11B is preloaded with new wire reels 10 for backup, and when tray 11A is exhausted, it is quickly switched to tray 11B; on the other hand, the two trays 11 are connected to the wire feeder at the same time to supply material to the casting line flow channel synchronously, forming a parallel working wood mode that doubles the processing capacity per unit time and improves the feeding efficiency.

[0027] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
