Description

Technical Field

[0001] This invention relates to the field of aluminum plate casting and rolling technology, and in particular to a titanium wire uniform feeding device. Background Technology

[0002] In the casting and rolling process of aluminum sheets, adding titanium wire to the molten aluminum can refine the grain structure of the cast and rolled aluminum strip, reduce casting defects (cracks, segregation, porosity), improve strength and toughness, improve plasticity and formability, obtain better surface quality and microstructure uniformity, and ultimately significantly improve the quality and subsequent processing performance of the cast and rolled aluminum strip billet.

[0003] Titanium wire is usually fed into the casting and rolling box continuously. Since the titanium wire enters the casting and rolling box vertically, the contact area with the aluminum melt is small, making it difficult to ensure the fusion quality of the titanium wire and the aluminum melt. The existing method is to set a feeding device on one side of the casting and rolling box. The front end of the feeding device is equipped with a collar. Before the titanium wire enters the casting and rolling box, it is first passed through the collar. The feeding device reciprocates, and the collar pulls the titanium wire to change the angle of descent, so that the titanium wire and the aluminum melt can be mixed evenly.

[0004] In this method, because the titanium wire is thin, the temperature change at the top of the casting and rolling box during the descent of the titanium wire will cause the titanium wire to sway. In addition, the size of the collar is small, making it difficult for the titanium wire to align with the collar when it descends. The worker can only use a rod to move the titanium wire so that it enters the collar. If the titanium wire fails to pass through the collar, the machine must be stopped and the titanium wire raised again to re-align it. This method is extremely demanding on the operator's skill level and has great operational difficulty. Summary of the Invention

[0005] To address the technical problems existing in the background art, the purpose of this invention is to provide a titanium wire uniform feeding device that can pull the titanium wire without aligning the titanium wire with the feeding device, thereby reducing the operational difficulty of titanium wire feeding.

[0006] To achieve the above objectives, the technical solution provided by the present invention is as follows: A titanium wire uniform feeding device includes a rod assembly, a driving component, and a gripper structure. The gripper structure includes two grippers that can open and close to each other, a support cylinder, and several connecting rods. One end of each gripper is hinged to the support cylinder. The connecting rods are hinged to the grippers, and one end of each connecting rod is slidably connected to the support cylinder. Adjusting the position of the connecting rods on the support cylinder allows the grippers to open or close. The grippers are connected to the outside of the titanium wire and closed, so that the titanium wire is located in the middle of the grippers. The driving component drives the rod assembly to perform linear reciprocating motion, which can change the descent position of the titanium wire, allowing the titanium wire to enter the molten aluminum uniformly.

[0007] Preferably, the rod assembly includes a support rod and a swing rod, which are hinged together. The drive component includes a turntable and a support base, which are rotatably connected to the support base. A support block is eccentrically disposed on the turntable, and the swing rod and the support block are hinged together.

[0008] Preferably, the system also includes a limiting component, which includes a bracket and several rotating wheels. The rotating wheels are arranged opposite each other inside the bracket, with the center of each rotating wheel recessed. A support rod is arranged between the rotating wheels, and the circumferential surfaces of the rotating wheels and the support rod are in contact.

[0009] Preferably, the limiting assembly also includes a support, wherein a wheel is rotatably connected to the support, and the support and the bracket are detachably connected.

[0010] Preferably, one end of the support cylinder and the support rod are detachably connected.

[0011] Preferably, one end of the support cylinder is provided with several protrusions, and the gripper includes gripper I and gripper II. The middle of gripper I is through-connected, one end of gripper I is hinged to the protrusions, and one end of gripper II is hinged to the protrusions. When gripper I and gripper II approach each other, gripper II can extend into the middle of gripper I.

[0012] Preferably, the gripper I is provided with a connecting block I, the gripper II is provided with a connecting block II, the connecting rod includes a connecting rod I and a connecting rod II, the connecting rod I and the connecting block I are hinged, the connecting rod II and the connecting block II are hinged, and the connecting rod I and the connecting rod II are concentrically arranged.

[0013] Preferably, the support cylinder is provided with a sliding groove, and a sliding rod is slidably disposed in the sliding groove. One end of the connecting rod I is hinged to the sliding rod, and one end of the connecting rod II is hinged to the sliding rod.

[0014] Preferably, the gripper structure further includes an adjusting member, which includes a collar and a stop rod. The collar is slidably connected to the support rod, and the stop rod is inserted into one end of the collar. One end of the stop rod is connected to a slide rod.

[0015] Preferably, adjusting bolts are provided on both sides of the collar, and the adjusting bolts can extend into the collar and abut against the support rod.

[0016] The present invention has the following advantages and beneficial effects: In this invention, the titanium wire uniform feeding device is located outside the casting and rolling box, and the grippers are aligned with the outside of the titanium wire. When the titanium wire descends, the grippers close and enclose the wire, eliminating the need for workers to rely on experience and reducing the overall operational difficulty. This also ensures the connection quality between the grippers and the titanium wire, preventing connection errors. Because the support rod is long and located far from the casting and rolling box, worker operation is safe and reliable. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] Example like Figures 1-8 As shown, a titanium wire uniform feeding device includes a rod assembly 4, a limiting assembly 5, a driving component 3, and a gripper structure. The driving component 3 is located outside the casting and rolling box 1 and is connected to the rod assembly 4. The limiting assembly 5 supports the rod assembly 4 and limits the rod assembly 4 to move linearly only on one side of the casting and rolling box 1. The driving component 3 drives the rod assembly 4 to perform linear reciprocating motion above the casting and rolling box 1. The gripper structure is located at one end of the rod assembly 4 and above the casting and rolling box 1. The gripper structure can open and close. When the titanium wire descends, the gripper connects to the outside of the titanium wire and closes, so that the titanium wire is located inside the gripper. The driving component 3 drives the rod assembly 4 to perform linear reciprocating motion, synchronously linking the gripper structure and the titanium wire inside the gripper structure to reciprocate, thereby changing the descending position of the titanium wire and allowing the titanium wire to enter the molten aluminum uniformly.

[0022] like Figure 1 , Figure 3 , Figures 5-8 As shown, the rod assembly 4 includes a support rod 42 and a swing rod 41, which are hinged together. The drive component 3 includes a turntable 31 and a support base 32. A motor 33 is connected to the support base 32. The turntable 31 is rotatably connected to the support base 32. The motor 33 drives the turntable 31 to rotate. A support block 311 is eccentrically arranged on the turntable 31. The swing rod 41 and the support block 311 are hinged together. When the turntable 31 rotates, the support block 311 drives the swing rod 41 to move, which in turn drives the support rod 42 to move. This movement method can also be replaced by telescopic components such as cylinders. However, since there is a lot of dust in the factory, if telescopic components such as cylinders are used for a long time, the telescopic shaft end will be covered by dust, which will not only affect the feeding efficiency but also make it difficult to clean. Therefore, the rod assembly 4 and the drive component 3 are used. The connection between the two is stable and it is convenient to clean the dust at the hinge point regularly.

[0023] like Figure 1 , Figure 2 , Figures 5-8As shown, the limiting component 5 includes a support 53, a bracket 51, and several rotating wheels 52. The bracket 51 has a "U"-shaped structure and is detachably connected to the worktable outside the casting and rolling box 1 by bolts. The bolt connection not only facilitates disassembly and assembly but also makes it easy to adjust the overall position of the limiting component 5. Several rotating wheels 52 are arranged opposite each other inside the bracket 51. The rotating wheels 52 are rotatable and have a concave center. A support rod 42 is arranged between the rotating wheels 52, and the circumferential surfaces of the rotating wheels 52 and the support rod 42 are in contact. One of the rotating wheels 52 is rotatably connected to the support 53. The support 53 and the bracket 51 are detachably connected by bolts. In this invention, three rotating wheels 52 are designed, with two rotating wheels 52 located at the lower end of the support rod 42. The two rotating wheels 52 located at the lower end of the support rod 42 are at the same height. The support 53 and a rotating wheel 52 are located at the upper end of the support rod 42. The three rotating wheels 52, two on top and one on the bottom, provide three-point limiting and support the support rod 42, thus limiting its lateral movement. In conjunction with the drive component 3, when the turntable 31 drives the swing arm 41, the multiple rotating wheels 52 limit the support rod 42, so that the support rod 42 can only reciprocate within the middle of the rotating wheel 52. The support 53 is connected by bolts. The height of the support 53 is designed according to the diameter of the support rod 42. If there is a gap between the upper end of the support rod 42 and the rotating wheel 52 after the support 53 and the bracket 51 are connected, the corresponding dimensions of the support 53 can be redesigned or a shim of appropriate size can be added between the support 53 and the bracket 51. Compared with the integral structure, this method reduces the requirements for machining accuracy and is more suitable for on-site work needs.

[0024] In the prior art, the cylinder shaft end needs to be supported by a support member. The cylinder shaft end and the support member are in surface contact, and the friction between them is relatively large. During long-term use, the temperature at the connection surface between the two will rise, resulting in greater wear on the cylinder shaft end and a larger load. In this invention, after designing the limiting component 5, the surface contact is changed to point contact while still providing support. The friction between the support rod 42 and the rotating wheel 52 is smaller, the wear of the support rod 42 is less, and the service life of the entire structure is extended.

[0025] like Figure 1 , Figure 3 , Figure 4 , Figures 5-8 As shown, the gripper structure includes two grippers that can open and close to each other, a support cylinder 6, an adjusting component, and several connecting rods. One end of the gripper is hinged to the support cylinder 6. One end of the support cylinder 6 and the support rod 42 are detachably connected by bolts. One end of the support cylinder 6 is hollow, and a hole is provided at the hollow section. The support rod 42 also has a hole. When the support cylinder 6 is inserted into the support rod 42, the holes are aligned with each other. The hole on the support rod 42 is a threaded hole. When the two holes are aligned, a bolt can be screwed into the hole to connect the support cylinder 6 and the support rod 42.

[0026] The connecting rod and the gripper are hinged, and one end of the connecting rod is slidably connected to the support cylinder 6. Adjusting the position of the connecting rod on the support cylinder 6 can open or close the gripper.

[0027] Several protrusions 62 are provided on both sides of the support cylinder 6. The gripper includes gripper I7 and gripper II8. The gripper has an arc-shaped structure. Gripper I7 is through the middle and one end of gripper I7 is hinged to protrusion 62. The protrusion 62 connected to gripper I7 is located at the middle position of gripper I7. One end of gripper II8 is hinged to protrusion 62. The protrusion 62 connected to gripper II8 is connected to the upper and lower ends of gripper II8 respectively. When gripper I7 and gripper II8 approach each other, gripper II8 can extend into the middle of gripper I7. This method makes gripper I7 and gripper II8 staggered when closed, which not only ensures that gripper I7 and gripper II8 can close in a ring shape, but also avoids collision between gripper I7 and gripper II8, thus increasing the service life of the device.

[0028] A connecting block I71 is provided on gripper I7, and a connecting block II81 is provided on gripper II8. Two sets of connecting rods are provided, including connecting rod I9 and connecting rod II91. Connecting rod I9 is ​​hinged to connecting block I71, and connecting rod II91 is hinged to connecting block II81. One end of connecting rod I9 and connecting rod II91 are concentrically positioned. A sliding groove 61 is provided on support cylinder 6, and a sliding rod 92 is slidably mounted within the sliding groove 61. One end of connecting rod I9 is ​​hinged to sliding rod 92, and one end of connecting rod II91 is hinged to sliding rod 92. Rod 92 passes through connecting rod I9 and connecting rod II91, which are connected in a V-shape. When the sliding rod 92 slides in the groove 61 towards the gripper, it drives connecting rod I9 and connecting rod II91 to move respectively. Connecting rod I9 pushes connecting block I71, causing gripper I7 to rotate about protruding block 62, increasing the angle between connecting rod I9 and connecting rod II91. Connecting rod II91 pushes connecting block II81, causing gripper II8 to rotate about protruding block 62, closing the gripper. When the sliding rod 92 moves towards the drive member 3, the movement is reversed, opening the gripper.

[0029] The adjusting component includes a collar 11 and a stop rod 111. The collar 11 is slidably connected to the support rod 42, and the stop rod 111 is inserted into one end of the collar 11. One end of the stop rod 111 is connected to the slide rod 92. Before installing the gripper assembly and the support rod 42, the collar 11 is first placed on the outside of the support rod 42, and then the support cylinder 6 and the support rod 42 are connected. The collar 11 is pushed to move outside the support rod 42, and the collar 11 drives the stop rod 111 to move, so that the stop rod 111 drives the slide rod 92 to move in the slide groove 61, thereby realizing the closing operation of the gripper. Adjusting bolts 112 are respectively provided on both sides of the collar 11. The adjusting bolts 112 can extend into the collar 11 and abut against the support rod 42. When the collar 11 is adjusted to a suitable position (the gripper is open or closed), the adjusting bolts 112 are rotated so that the adjusting bolts 112 abut against the support rod 42, restricting the movement of the collar 11 and keeping the gripper in the open or closed state.

[0030] The abutment 111 can support the slide rod 92, so that the slide rod 92 located at the lower end of the support cylinder 6 will not wobble at the position of the slide groove 61. In order to further strengthen the connection strength between the slide rod 92 and the slide groove 61, the slide groove 61 is designed as a T-shape and the slide groove 61 extends through one end of the support cylinder 6. The bottom shape of the slide rod 92 is consistent with the shape of the slide groove 61. The slide rod 92 extends into the slide groove 61 from one end. The T-shaped connection can prevent the slide rod 92 from falling out of the slide groove 61, further increasing the connection stability between the slide rod 92 and the slide groove 61, so that the slide rod 92 remains stable when sliding.

[0031] Working principle: The titanium wire uniform feeding device is set on the outside of the casting and rolling box 1. When the titanium wire descends into the casting and rolling box 1, it pushes the collar 11, causing the collar 11 to drive the push rod 111 to move towards the casting and rolling box 1. The push rod 111 drives the slide rod 92 to move in the slide groove 61. During the sliding process of the slide groove 61, the angle between connecting rod I 9 and connecting rod II 91 increases. At the same time, connecting rod I 9 and connecting rod II 91 push the gripper I 7 and gripper II 8 respectively, causing gripper I 7 to rotate about the protrusion 62 at one end as the axis, and causing gripper II 8 to rotate about the other end as the axis. The protruding block 62 at one end rotates around the axis, and the grippers I7 and II8 approach each other and surround the titanium wire. At this time, the collar 11 is fixed to the support rod 42 by adjusting the bolt 112. The motor 33 drives the turntable 31 to rotate, and the support block 311 on the turntable 31 drives the swing rod 41 to swing. When the swing rod 41 swings, it pulls the support rod 42 and its gripper structure, so that the support rod 42 and the gripper structure move in a straight line. As the titanium wire continues to descend, the angle of descent of the titanium wire changes, so that the titanium wire can fully fuse with the aluminum melt.

[0032] This is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
