[0025] In operation, guide cylinder 34 is used to connect with a feeder (such as a vibrating disc, etc.), and straight blank rod 50 is conveyed to guide cylinder 34 by the feeder; in the initial position, first positioning structure 41 is located at the rear side of lower module, and second positioning structure 42 is located below guide cylinder 34; blank rod 50 conveyed falls onto second positioning structure 42 and is positioned by it; material moving assembly 33 drives first positioning structure 41 and second positioning structure 42 to move, first positioning structure 41 approaches blank rod 50 that has been bent in forming groove 22 and positions it; material moving assembly 33 continues to drive first positioning structure 41 and second positioning structure 42 to move, and bent blank rod 50 follows first positioning structure 41 to move to the front side of lower module; first positioning structure 41 releases bent blank rod 50, and second positioning structure 42 releases straight blank rod 50, so that bent blank rod 50 can be taken out and the next straight blank rod 50 is placed.

[0026] As the above structure, material moving mechanism 30 arranged can automatically take out bent blank rod 50 after the mould is opened and place the next straight blank rod 50, which avoids manual taking and placing and can improve safety and operation efficiency. In addition, a chute can be usually arranged on the front top of lower die plate 20, and blank rod 50 released by first positioning structure 41 falls into the chute and then slides to the collecting frame for collection, so as to be transported to the next production equipment.

[0027] In the embodiment, the side wall of the forming groove 22 is concavely provided with a positioning groove 23, and the two ends of the positioning groove 23 extend to the top surface of the lower mold 21. The positioning groove 23 can avoid the rolling displacement of the blank rod 50 when the blank rod 50 is bent.

[0028] In the embodiment, the material moving assembly 33 comprises a linear module 331, a second support 332, a third support 333 and a lifting cylinder 334. The linear module 331 is arranged on the bottom plate 31 in the front-rear direction. The second support 332 is fixedly connected with the linear module 331. The third support 333 is arranged in the transverse direction and is longitudinally slidably connected with the second support 332. The lifting cylinder 334 is connected with the second support 332 and the third support 333 respectively. The first positioning structure 41 is fixedly arranged at the front end of the third support 333. The second positioning structure 42 is fixedly arranged at the top of the third support 333. The linear module 331 can drive the second support 332 to move in the front-rear direction. The lifting cylinder 334 can drive the third support 333 to lift relative to the second support 332. Since the bent blank rod 50 is located in the positioning groove 23, in order to ensure that the blank rod 50 is smoothly taken out, the first positioning structure 41 is first moved forward, and then the first positioning structure 41 is lifted after the first positioning structure 41 is close to and positions the blank rod 50. Then the first positioning structure 41 is continuously moved forward to the front side of the lower mold 21.

[0029] In the embodiment, the bottom rear side of the material guiding cylinder 34 is provided with a guide rod 35, the rear end of the guide rod 35 is provided with a first protrusion 351, the guide rod 35 is slidably sleeved with a baffle 36, the baffle 36 extends to the bottom surface of the material guiding cylinder 34, the guide rod 35 is sleeved with a first spring 37 between the baffle 36 and the first protrusion 351, and the top of the second support 332 is provided with a second protrusion 335 opposite to the baffle 36 in the front-rear direction. The feeding machine generally arranges and conveys straight blank rods 50, and a plurality of blank rods 50 are arranged in the longitudinal direction in the guide cylinder 14. The blank rods 50 can be prevented from falling by shielding the lower end opening of the material guiding cylinder 34 by the baffle 36. The second protrusion 335 can push the baffle 36 to move rearward when the second protrusion 335 moves rearward. When the second positioning structure 42 moves to the lower side of the guide cylinder 14, the blank rods 50 in the guide cylinder 14 can fall one to the second positioning structure 42. Then the second positioning structure 42 and the second protrusion 335 move forward, and the baffle 36 is immediately pushed forward by the first spring 37 to reset, so as to prevent the remaining blank rods 50 in the guide cylinder 14 from falling out.

[0030] In the embodiment, the first positioning structure 41 and the second positioning structure 42 are both electromagnets. The top surface of the second positioning structure 42 is arranged in an inclined manner and is low in front and high in rear. Specifically, the electromagnet mainly comprises a core and a coil. For the first positioning structure 41, the outer contour of the core can be arranged in a shape corresponding to the forming groove 22, so as to be closely attached to the bent blank rod 50. For the second positioning structure 42, the top surface of the core can be an inclined surface (the included angle between the top surface and the horizontal plane is 1-5°).

[0031] The second positioning structure 42 is powered to generate magnetic attraction to the blank rod 50, and after rising, the blank rod 50 on the second positioning structure 42 is in a position flush with or slightly higher than the top surface of the lower mold module 21; after the second positioning structure 42 is powered off to cancel the magnetism, the blank rod 50 can roll forward to the positioning groove 23.

[0032] In the embodiment, the bottom surface of the upper mold module is provided with a first channel 111, the first channel 111 is slidably inserted with an adjusting rod 12, and the first channel 111 is provided with a second spring 13 at the top of the adjusting rod 12, the lower end of the adjusting rod 12 extends out of the first channel 111, and the lower end of the adjusting rod 12 has a guide slope. After the blank rod 50 rolls to the positioning groove 23, there may be a situation that the blank rod 50 is axially offset; when the mold is closed, the guide slope first contacts the blank rod 50 and can push it to move to the correct position in the axial direction, and the adjusting rod 12 can be retracted in the first channel 111 after abutting against the lower mold module 21. The second spring 13 has a large elastic coefficient and is always compressed to store power in the first channel 111, so that when the guide slope pushes the blank rod 50, the adjusting rod 12 can be prevented from moving upward and retracting.

[0033] In the embodiment, the adjusting rod 12 is provided with two and is arranged on both sides of the forming groove 22. Through the structure, the offset of the blank rod 50 on both sides of the axial direction can be pushed and corrected by the adjusting rod 12, so that the blank rod 50 is ensured to be in the correct position.
