[0044] The names of the messages or information exchanged between multiple devices in the implementation manners of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0045] Refer to Figures 1-6, a tungsten wire cutting device, comprising a cutting table 1, a straightening component 2, a cutting component 3 and a discharge hopper 4. The straightening component 2 and the cutting component 3 are respectively located on both sides of the cutting table 1. The straightening component 2 is used to straighten the tungsten wire to be processed and cut it through the cutting component 3. After cutting, the tungsten wire is discharged through the discharge hopper 4;

[0046] The straightening component 2 includes a fixing plate 21, a first guiding cylinder 22, a guide rail 23, a movable seat 24 and a second guiding cylinder 25. The fixing plate 21 is arranged on the cutting table 1. A plurality of first guiding cylinders 22 are arranged on the fixing plate 21 at intervals. Two groups of guide rails 23 are arranged symmetrically on both sides of the fixing plate 21. The movable seat 24 is movably arranged on the guide rail 23. A plurality of second guiding cylinders 25 are arranged on the movable seat 24 at intervals. The first guiding cylinders 22 and the second guiding cylinders 25 are staggered and form a clamping area through which the tungsten wire passes. When the movable seat 24 moves on the guide rail 23, the clamping area increases or decreases. The tungsten wire passes through the clamping area and is limited by the first guiding cylinder 22 and the second guiding cylinder 25, so that the tungsten wire can only move in one direction during the movement, thus realizing the straightening of the bent tungsten wire. The setting of the two groups of second guiding cylinders 25 can realize the simultaneous straightening and cutting operations of two groups of tungsten wires on one device, improving the work efficiency;

[0047] The cutting component 3 includes a bracket 31, a telescopic driving component 32 and a cutter seat 33. The bracket 31 is arranged on the cutting table 1. The telescopic driving component 32 is arranged on the bracket 31. The piston part of the telescopic driving component 32 passes through the bracket 31 and is connected to the cutter seat 33. The telescopic driving component 32 is a pneumatic push rod in the prior art, and provides power for the cutter seat 33 to cut the tungsten wire;

[0048] The discharge hopper 4 is arranged outside the cutting table 1 and on one side close to the bracket 31.

[0049] Based on the above structure, the tungsten wire moves from the position of the straightening assembly 2 to the position of the cutting assembly 3 on the cutting table 1. Since the first guide cylinder 22 and the second guide cylinder 25 are provided in the straightening assembly 2, when the tungsten wire passes between the first guide cylinder 22 and the second guide cylinder 25, it is subjected to the mutual extrusion force between the first guide cylinder 22 and the second guide cylinder 25, thereby straightening the bent tungsten wire. And because several first guide cylinders 22 and second guide cylinders 25 are provided, the tungsten wire is gradually straightened, avoiding the risk of breakage or the generation of tiny cracks caused by directly and quickly straightening the tungsten wire. Moreover, since the second guide cylinder 25 is installed on the movable seat 24, and the movable seat 24 is located on the guide rail 23, by changing the position of the movable seat 24 according to the diameter of the tungsten wire, the distance between the second guide cylinders 25 is changed, thereby enhancing the flexibility of use of the straightening assembly 2. When the tungsten wire moves to the position of the cutting assembly 3, it is in a straight line shape. The cutter holder 33 is controlled by the telescopic driving member 32 to approach the tungsten wire and cut it. Since the discharge hopper 4 is provided on one side of the cutting table 1, the cut tungsten wire will be discharged from the discharge hopper 4. The tungsten wire is prevented from splashing when being cut through the limitation of the discharge hopper 4. Through the setting of the straightening assembly 2 and the discharge hopper 4, the bent tungsten wire can be straightened, solving the problem that the bent tungsten wire needs to be manually straightened after being cut, which poses a risk of breakage.

[0050] In one of the implementation manners, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 also includes a pressure roller mechanism 5. The pressure roller mechanism 5 is located between the straightening assembly 2 and the cutting assembly 3. The pressure roller mechanism 5 includes a lifting assembly 51, a driving roller 52, a driven roller 53 and a driving motor 54. The driving motor 54 is a servo driving motor in the prior art, providing power for the rotation of the driving roller 52;

[0051] Grooves 11 and receiving grooves 12 are provided on both sides of the cutting table 1. The receiving groove 12 is located below the groove 11. The lifting assembly 51 includes a support 511, a screw rod component 512 and a sliding seat 513. The support 511 is provided in the groove 11. The screw rod component 512 is rotatably provided in the groove 11. The sliding seat 513 is installed on the screw rod component 512. One end of the screw rod component 512 passes through the support 511 and is provided with a hand wheel. The driven roller 53 is rotatably provided between two sliding seats 513. The tungsten wire passes between the driving roller 52 and the driven roller 53;

[0052] Both ends of the driving roller 52 are rotatably provided in the receiving groove 12. The driving motor 54 is provided on one side of the cutting table 1 and is connected to the driving roller 52.

[0053] Based on the above structure, since one end of the tungsten wire abuts against the outer peripheral surface of the driving roller 52, the driving roller 52 can be driven to rotate by the driving motor 54, so that the driving roller 52 can drive the tungsten wire to move, thereby driving the tungsten wire to move from the straightening assembly 2 to the traction assembly 6. By clamping the tungsten wire with the driving roller 52 and the driven roller 53, the stability of the tungsten wire during movement is ensured. Since the driven roller 53 is installed on the slide block 513 in the lifting assembly 51, by rotating the screw rod component 512, the screw rod component 512 can drive the slide block 513 to move along the rotation direction of the screw rod component 512, so that the driven roller 53 approaches or moves away from the driving roller 52, thereby enabling the pressure roller mechanism 5 to adjust the position of the driven roller 53 according to the size of the tungsten wire, thus improving the flexibility of use of the pressure roller mechanism 5.

[0054] In one implementation, referring to Figure 1 , Figure 2 , Figure 3 and Figure 6 , the straightening assembly 2 further includes a push rod component 26. The push rod component 26 is arranged on the cutting table 1 and is located on the side of the guide rail 23 away from the fixed plate 21. The push rod component 26 is a pneumatic push rod in the prior art. The piston end of the push rod component 26 is connected to the movable seat 24. Through the cooperation of the push rod component 26, the movable seat 24 approaches or moves away from the fixed plate 21. By arranging the push rod component 26, the automatic movement of the movable seat 24 can be realized, so that the second guide cylinder 25 abuts against the tungsten wire.

[0055] In one implementation, referring to Figure 1 and Figure 2 , it further includes a traction assembly 6. The traction assembly 6 includes a support plate 61, a shaft rod 62, a mounting bracket 63 and a traction roller 64. Two groups of support plates 61 are arranged and symmetrically distributed on one side of the cutting table 1 close to the straightening assembly 2. The shaft rod 62 is arranged on the support plate 61. The mounting bracket 63 is sleeved on the shaft rod 62, so that the mounting bracket 63 has the freedom of rotation with the shaft rod 62 as the center;

[0056] The traction roller 64 is rotatably arranged between the two groups of support plates 61. A ring-shaped wire groove 641 is arranged on the traction roller 64. Several ring-shaped wire grooves 641 are arranged and evenly distributed along the length direction of the traction roller 64. The ring-shaped wire groove 641 is used for placing the tungsten wire to be processed. When the mounting bracket 63 rotates, the traction roller 64 rotates synchronously. When the traction roller 64 rotates, its position changes, so as to adjust the position, thereby changing the tension generated during the traction of the tungsten wire and improving the stability during the processing of the tungsten wire.

[0057] In one implementation, referring to Figure 2 and Figure 5, a discharge hopper 4 is provided with a through groove 41 extending into the interior of the discharge hopper 4. A baffle 42 is movably arranged on the through groove 41. A discharge area is formed between the baffle 42 and the discharge hopper 4. As the baffle 42 moves in the through groove 41, the discharge area increases or decreases. The change of the discharge area can enable the cut tungsten wire to be discharged from a specified area, avoiding the splashing of the tungsten wire.

[0058] In one implementation, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , a sliding groove 13 is arranged on the cutting table 1. The sliding groove 13 is located between the straightening assembly 2 and the traction assembly 6. A limit seat 14 is movably arranged on the sliding groove 13. The limit seat 14 has a through hole through which the tungsten wire passes. The setting of the through hole can limit the tungsten wire, thereby preventing the tungsten wire from shaking during movement. And through the cooperation of the limit seat 14 and the sliding groove 13, the position of the limit seat 14 can be adjusted according to the distance between the first guide cylinder 22 and the second guide cylinder 25.

[0059] In one implementation, referring to Figure 1 and Figure 2 , the cutting table 1 is further provided with an operation panel 15. The operation panel 15 is electrically connected to the telescopic drive component 32, the drive motor 54 and the push rod component 26. Through the operation panel 15, the telescopic of the telescopic drive component 32 and the push rod component 26 can be controlled, and the telescopic distance can be understood. And the connection with the drive motor 54 can realize the adjustment of the rotation speed and rotation time of the drive motor 54.

[0060] In one implementation, referring to Figure 1 , Figure 2 and Figure 5 , the baffle 42 is provided with a handrail groove 421. The setting of the handrail groove 421 facilitates the operator to hold the baffle 42.
