Description

Technical Field

[0001] This utility model relates to the field of hafnium wire processing technology, specifically to an electrode hafnium wire feeding device. Background Technology

[0002] The electrode hafnium wire feeding device is designed to meet industrial needs. Hafnium wire, as a key material, has significant thermal stability and corrosion resistance, and is an important component in electrode manufacturing. During electrode operation, it faces extreme conditions such as high temperature and high pressure. Thanks to its good thermal stability and deformation resistance, hafnium wire can maintain the long-term stability and high efficiency of the electrode.

[0003] For example, the patent with announcement number CN209238880U discloses a small stamping feeding device. By integrating multiple functions such as feeding, cleaning, heating, rolling, drawing and winding, it realizes the automated processing of high-purity hafnium wire from hafnium wire to finished product, which improves production efficiency. However, when using this patent, the hafnium wire length is inconsistent, which will lead to feeding and rolling errors, affecting the accuracy of hafnium wire length and diameter, and even causing production interruption.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an electrode hafnium wire feeding device to achieve the effects of fixed-length cutting and quantitative feeding.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an electrode hafnium wire feeding device, including a base, four symmetrically arranged support frames are fixedly installed on the top of the base, two symmetrically arranged rotating rods are rotatably installed inside the support frames, rotating rollers are fixedly sleeved on the outer circumferential surface of the two rotating rods, and a feeding belt is sleeved on the two rotating rollers together.

[0007] A guide plate is fixedly installed on the top of the base. An upper blade and a lower blade are slidably installed inside the guide plate. A fixing frame is fixedly installed on the top of the base. Two symmetrically arranged feeding rollers are rotatably installed inside the fixing frame. A transmission rod is fixedly nested inside the feeding roller. The transmission rod and the rotating rod are connected to a synchronous belt through a synchronous pulley set. A ratchet and an upper rotating gear are fixedly installed on the outer circumference of the transmission rod. A lower rotating gear is fixedly connected to one side of the other feeding roller.

[0010] Furthermore, three circumferentially distributed baffles are fixedly installed on one side of the turntable, and three circumferentially distributed pawls are movably hinged to one side of the turntable. A spring is fixedly connected between the pawls and the baffles.

[0011] Furthermore, a first rack is fixedly connected to the bottom of the upper blade, and a second rack is fixedly connected to the top of the lower blade.

[0020] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] like Figure 1-4 As shown, this application provides an electrode hafnium wire feeding device, a base 1, and four symmetrically arranged support frames 2 fixedly installed on the top of the base 1. Two symmetrically arranged rotating rods 5 are rotatably installed inside the support frames 2. Rotating rollers 4 are fixedly sleeved on the outer circumference of the two rotating rods 5. The two rotating rollers 4 are together sleeved with a feeding belt 3. A guide plate 6 is fixedly installed on the top of the base 1. An upper blade 7 and a lower blade 22 are slidably installed inside the guide plate 6. A fixing frame 12 is fixedly installed on the top of the base 1. Two symmetrically arranged feeding rollers 11 are rotatably installed inside the fixing frame 12. A transmission rod 16 is fixedly nested inside the feeding roller 11. The transmission rod 16 and the rotating rods 5 are together sleeved with a synchronous belt 10 through a synchronous pulley group. A ratchet 24 and an upper rotating gear 17 are fixedly sleeved on the outer circumference of the transmission rod 16. A lower rotating gear 18 is fixedly connected to one side of the other feeding roller 11. The upper rotating gear 17 and the lower rotating gear 18 are meshed together.

[0022] like Figure 1-4 As shown, a rotating rod 5 is fixedly nested inside the rotating roller 4, and a connecting plate 13 is fixedly connected to the top of the fixed frame 12. A round rod is rotatably installed on one side of the connecting plate 13.

[0023] like Figure 1-4As shown, a follower gear 14 is fixedly sleeved on the outer circumference of the round rod. A turntable 15 is fixedly connected to one side of the follower gear 14. A connecting rod 8 is fixedly connected to one side of the upper blade 7. The connecting rod 8 is slidably disposed inside the guide plate 6. A transmission rack 9 is fixedly connected to one end of the connecting rod 8. The transmission rack 9 is slidably connected inside the connecting plate 13. The transmission rack 9 meshes with the follower gear 14. Three circumferentially distributed baffles 26 are fixedly disposed on one side of the turntable 15. Three circumferentially distributed baffles 26 are movably hinged to one side of the turntable 15. Evenly distributed pawls 25 are fixedly connected to the baffle 26 by springs 23. The bottom of the upper blade 7 is fixedly connected to the first rack 20, and the top of the lower blade 22 is fixedly connected to the second rack 19. The first rack 20 and the second rack 19 are slidably connected to the guide plate 6. The guide plate 6 is rotatably mounted with a cooperating gear 21, which meshes with both the first rack 20 and the second rack 19. The guide plate 6 has a guide groove inside, and the connecting rod 8 is slidably connected inside the guide groove.

[0024] The working principle of this utility model is as follows: When feeding the electrode hafnium wire, firstly, one end of the hafnium wire is pulled out from the hafnium wire roll and introduced along the linear guide groove opened between the two feeding rollers 11. It is continuously pushed until one end of the hafnium wire passes through the shearing area formed by the upper blade 7 and the lower blade 22 and is located above the feeding belt 3. The length of the hafnium wire passing through is adjusted to meet the required size.

[0025] Then, the cylinder is activated. Since the output end of the cylinder is fixedly connected to the top of the upper blade 7, the piston of the cylinder extends and pushes the upper blade 7 to move downward. At the same time, it drives the first rack 20 fixedly connected to it to move downward together. The first rack 20 drives the second rack 19 and the lower blade 22 to slide upward synchronously through the cooperating gear 21. When the upper blade 7 and the lower blade 22 are in contact, the hafnium wire is cut.

[0026] After the cutting is completed, the cylinder piston retracts, causing the upper blade 7 to slide upward and reset. At this time, the connecting rod 8 fixedly connected to the upper blade 7 will also drive the transmission rack 9 to move upward. Because the transmission rack 9 meshes with the follower gear 14, the follower gear 14 rotates counterclockwise, thereby driving the round rod and the turntable 15 to rotate counterclockwise together. When the pawl 25 on one side of the turntable 15 rotates with the turntable 15, it pushes the ratchet 24, the transmission rod 16 and the upper rotating gear 17 to rotate counterclockwise. The lower rotating gear 18 meshing with the upper rotating gear 17 will rotate clockwise. At this time, the hafnium wire in the trough will continue to be conveyed forward for a distance to prepare for the next cutting process, thus realizing the fixed-length cutting of the hafnium wire.

[0027] In addition, the rotation of the transmission rod 16 drives the rotating rod 5 and the rotating roller 4 to rotate together through the synchronous belt 10, which in turn drives the feeding belt 3 to rotate. The cut hafnium wire will be conveyed forward a certain distance by the feeding belt 3.

[0028] It should be noted that when the upper blade 7 moves downward, the transmission rack 9 also moves downward and drives the turntable 15 to rotate clockwise. At this time, the pawl 25 on one side of the turntable 15 also rotates clockwise. However, during this process, the pawl 25 is pushed upward along the outer circumference of the ratchet 24, so it does not obstruct the rotation of the ratchet 24. In this state, the two feeding rollers 11 are stationary, and the hafnium wire is also stationary. Specifically, the hafnium wire remains stationary during the cutting process. Only after the cutting is completed does the feeding roller 11 start to rotate, automatically conveying the hafnium wire forward. At the same time, the feeding belt 3 also rotates, continuing to convey the previously cut hafnium wire forward. This design achieves pre-cut hafnium wire to a fixed length, ensuring that the length of the hafnium wire cut each time is consistent, thereby reducing subsequent processing errors caused by inconsistent lengths. At the same time, the feeding belt 3 conveys the hafnium wire sequentially, ensuring the quantity of hafnium wire conveyed each time, avoiding the accumulation or loss of hafnium wire during the conveying process, thereby ensuring the uniformity and consistency of the feeding.

[0029] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
