The conductor core 2 has a wire ejection hole extending along the axis of the conductor core 2, and the metal wire is ejected from the wire ejection hole.

[0044] A forming mechanism 3 is mounted on the frame 1. The forming mechanism 3 includes bending cutters 31, second extrusion forming cutters 33, third extrusion forming cutters 34, fourth extrusion forming cutters 35, and marking forming cutters 36, which are circumferentially spaced around the axis of the conductor mandrel 2 and mounted on the frame 1 via a moving assembly 4. The moving assembly 4 is used to control the corresponding cutters to move closer to or further away from the conductor mandrel 2. The bending cutter 31 is used to process the first bent portion 52 and the second bent portion 53 of the finished part 5. The first extrusion forming cutter 32, the second extrusion forming cutter 33, and the fourth extrusion forming cutter 35 are used to process the first extruded portion 51 of the finished part 5. The second extrusion forming cutter 33 and the third extrusion forming cutter 34 are used to process the second extruded portion 54 of the finished part 5. The third extrusion forming cutter 34 and the marking forming cutter 36 are used to process the marking portion 55 of the first extruded portion 51. A cutting and separating cutter 37 is also mounted on the frame 1. The cutting and separating cutter 37 is used to cut and separate the finished part 5 from the subsequent wire.

[0045] In this invention, after the straightened wire is ejected from the wire ejection hole of the conductor mandrel 2, the finished part 5 can be automatically and continuously processed and formed under the combined action of the bending cutter 31, the first extrusion forming cutter 32, the second extrusion forming cutter 33, the third extrusion forming cutter 34, the fourth extrusion forming cutter 35, the marking forming cutter 36, and the cutting and separating cutter 37. This meets the needs of batch processing of the finished part 5, effectively improves production capacity, and enhances stability.

[0046] Please refer to the accompanying drawings in the instruction manual. Figure 2 , Figure 9 , Figure 10 and Figure 11 The first extrusion molding tool 32, the second extrusion molding tool 33 and the fourth extrusion molding tool 35 are arranged in a triangular pattern.

[0047] The first extrusion forming tool 32 has a first extrusion groove 321, and the fourth extrusion forming tool 35 has a fourth extrusion groove 351. The first extrusion groove 321 and the fourth extrusion groove 351 cooperate to form the first extrusion part 51 of the finished part 5.

[0048] The first extrusion forming tool 32 is fixedly mounted with a plurality of first positioning pins 322, and the fourth extrusion forming tool 35 is provided with a plurality of fourth extrusion grooves 351 corresponding one-to-one with the first positioning pins 322.

[0049] The first extrusion forming tool 32 is also fixedly installed with a second positioning pin 323, and the second extrusion forming tool 33 is provided with a second positioning hole 332. The second positioning pin 323 and the second positioning hole 332 are inserted together to achieve the positioning effect.

[0050] In this invention, after the wire extends from the wire ejection hole, the first extrusion forming tool 32 approaches the wire and first contacts it. Then, the second extrusion forming tool 33 abuts against the first extrusion forming tool 32, and is positioned by the second positioning pin 323 and the first positioning pin 322. The fourth extrusion forming tool 35 then abuts against the first extrusion forming tool 32, and is positioned by the first positioning pin 322 and the first positioning hole 352. The wire is extruded by the first extrusion groove 321 and the fourth extrusion groove 351 to form the first extrusion part 51 of the finished product 5. During the extrusion process, the second extrusion forming tool 33 assists in supporting the first extrusion forming tool 32 to prevent the first extrusion forming tool 32 from deforming, thus ensuring the forming accuracy of the first extrusion part 51.

[0051] Please refer to the accompanying drawings in the instruction manual. Figure 3 , Figure 4 and Figure 9 The bending cutter 31 has a bending groove 311. After the first extrusion part 51 of the finished part 5 is formed, the bending cutter 31 moves closer to the wire so that the wire enters the bending groove 311 and bends the wire downward to form the first bending part 52. Then the wire is ejected for a set length, so that the bending cutter 31 moves closer to the wire again and bends the wire downward to form the second bending part 53.

[0052] Please refer to the accompanying drawings in the instruction manual. Figure 5 , Figure 9 , Figure 10 , Figure 12 and Figure 13 The second extrusion forming tool 33 and the third extrusion forming tool 34 are arranged opposite to each other, and the marking forming tool 36 is arranged perpendicular to the third extrusion forming tool 34;

[0053] The second extrusion forming tool 33 has a second extrusion groove 331, and the third extrusion forming tool 34 has a third extrusion groove 341. The second extrusion groove 331 and the third extrusion groove 341 cooperate to form the second extrusion part 54 of the finished part 5.

[0054] The second extrusion forming tool 33 has a third positioning hole 333, and the third extrusion forming tool 34 has a third positioning pin 343 fixedly installed. The third positioning hole 333 and the third positioning pin 343 are inserted together to achieve the positioning effect.

[0055] The third extrusion forming tool 34 has a locking groove 342, and the marking forming tool 36 has a locking block 361 fixedly installed on it. The locking groove 342 and the locking block 361 are engaged and inserted. The locking block 361 has a receiving groove 362 for accommodating the bending foot of the wire with the first extrusion part 51. The inner wall of the receiving groove 362 is fixedly installed with a marking forming block 363 for forming the marking part 55 of the finished part 5.

[0056] In this invention, both the second extrusion forming cutter 33 and the third extrusion forming cutter 34 approach the wire and are positioned by the third positioning hole 333 and the third positioning pin 343. Under the extrusion of the second extrusion forming cutter 33 and the third extrusion forming cutter 34, the wire is extruded and formed into the second extrusion part 54 of the finished product 5 by the cooperation of the second extrusion groove 331 and the third extrusion groove 341. Then, the marking forming cutter 36 approaches the second extrusion forming cutter 33 and presses the bent foot of the wire with the first extrusion part 51 against the side wall of the engagement groove 342 of the third extrusion forming cutter 34, so that it is accommodated by the side wall of the engagement groove 342 and the receiving groove 362. Under the action of the marking forming block 363, the marking part 55 is formed on the first extrusion part 51.

[0057] Please refer to the accompanying drawings in the instruction manual. Figure 6 and Figure 10 The cutting and separating tool 37 includes a cutting blade 371 and a floating cutting assembly. Both the cutting blade 371 and the floating cutting assembly are mounted on the frame 1 via a moving assembly 4. The two are arranged opposite each other on both sides of the conductor core 2 to achieve a cutting effect.

[0058] The floating cutting assembly includes a receiving block 372, a sliding rod 373, and a spring 374. One end of the sliding rod 373 is slidably connected to the moving end of the moving assembly 4, and the other end of the sliding rod 373 is fixedly connected to the receiving block 372. The spring 374 is sleeved on the outside of the sliding rod 373, and both ends of the spring 374 abut against the receiving block 372 and the moving end of the moving assembly 4, respectively. The cutting blade 371, in cooperation with the receiving block 372, can achieve the cutting effect on the finished part 5.

[0059] The cutting and separating blade 37 also includes a blower pipe 375 installed on the floating cutting assembly, which is used to blow air onto the finished part 5 after it is cut to assist the finished part 5 in separating from the subsequent wire.

[0060] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, the moving component 4 includes a sliding seat 41 and a sliding block 42. The sliding seat 41 is fixedly connected to the frame 1, and the sliding block 42 is slidably connected to the sliding seat 41, so that the sliding block 42 can slide along the sliding seat 41 to move away from or closer to the wire mandrel 2. The frame 1 is also equipped with a driving mechanism (not shown in the figure) for driving the sliding block 42 to slide. In this embodiment, the driving mechanism can adopt existing technology, such as a servo linear slide, a cam drive structure, etc., which will not be described in detail here.

[0061] In some embodiments, such as Figures 1-13 As shown in the preferred embodiment of this utility model, a processing method for a molybdenum wire bending continuous bending device includes the following steps:

[0062] Step 1: The wire is ejected from the ejection hole of the conductor core 2;

[0063] Step 2: The first extrusion forming tool 32 approaches the wire and first contacts the wire. Then the second extrusion forming tool 33 abuts against the first extrusion forming tool 32 to provide support. Then the fourth extrusion forming tool 35 abuts against the first extrusion forming tool 32, so that the wire is extruded by the first extrusion groove 321 on the first extrusion forming tool 32 and the fourth extrusion groove 351 on the fourth extrusion forming tool 35 to form the first extrusion part 51 of the finished part 5.

[0064] Step 3: The bending cutter 31 moves closer to the wire so that the wire enters the bending groove 311 and bends the wire downward to form the first bending part 52. Then the wire is ejected from the wire ejection hole, and the bending cutter 31 moves closer to the wire again to bend the wire downward to form the second bending part 53.

[0065] Step 4: The second extrusion forming tool 33 and the third extrusion forming tool 34 both move closer to the wire, so that the wire is extruded by the second extrusion groove 331 on the second extrusion forming tool 33 and the third extrusion groove 341 on the third extrusion forming tool 34 to form the second extrusion part 54 of the finished product 5.

[0066] Step 5: The marking forming cutter 36 approaches the second extrusion forming cutter 33 and presses the bent foot of the wire with the first extrusion part 51 against the side wall of the engagement groove 342 of the third extrusion forming cutter 34, so that it is limited by the engagement groove 342 side wall and the receiving groove 362, and the marking part 55 is formed on the first extrusion part 51 under the action of the marking forming block 363.

[0067] Step 6: The cutter 371 and the floating cutting assembly cut the finished part 5 in half. At the same time, the blower tube 375 blows air onto the finished part 5 after it is cut to help separate the finished part 5 from the subsequent wire.
