[0048] Referring to Figure 5As shown, in one embodiment of the present application, the wire forming die changing device further comprises a magazine plate 42, a guide rail 43, a guide rail motor 44 and an upper die cylinder 45. The guide rail 43 is vertically installed on the standby table 40. The magazine plate 42 is slidably installed on the guide rail 43 and connected with the output end of the guide rail motor 44. The plane where the magazine plate 42 is located is parallel to the plane where the conversion table 20 rotates. The guide rail motor 44 can drive the magazine plate 42 to move vertically along the guide rail 43. The magazine plate 42 can be provided with a plurality of die standby positions 421, for example, the number of die standby positions 421 can be 3. The die standby position 421 can be provided with a plurality of positioning pins 4211, for example, the number of positioning pins 4211 can be 4. One positioning pin 4211 can cooperate with one positioning hole 5112 or one positioning hole 5122 of the die to be replaced 51. The die standby position 421 is provided with a plurality of upper die holes 4212. The die standby position 421 is further provided with a plurality of magnetic blocks 4213.

[0049] Please refer to Figure 1 As shown, in one embodiment of the present application, when the wire forming die changing device performs the die unloading operation, first, the conversion table 20 rotates clockwise by 90°, the clamping cylinder 232 of the clamping mechanism 23 retracts, and the clamping block 231 releases the working die 50. The magazine plate 42 moves along the guide rail 43, aligns an empty die standby position 421 with the working die 50, and then stops moving. The two die unloading cylinders 33 retract at the same time, drive the die unloading plate 30 to move along the plane perpendicular to the plane where the conversion table 20 rotates, and the moving direction is to move close to the magazine plate 42 until the die unloading rod 31 contacts the working die 50. The die unloading cylinder 33 continues to drive the die unloading plate 30 to move, and the die unloading rod 31 pushes the working die 50 to move close to the magazine plate 42. At this time, the fixed rod 22 gradually separates from the T-shaped slot of the working die 50, and the positioning hole on the working die 50 cooperates with the positioning pin 4211 on the die standby position 421. When the working die 50 completely separates from the clamping frame 21 and contacts the magnetic block 4213, the die unloading cylinder 33 stops retracting. Then, the die unloading cylinder 33 extends to drive the die unloading plate 30 to reset, and the above operation completes the die unloading operation.

[0050] Please refer to Figure 1As shown, in one embodiment of the present application, when the wire forming die changing device performs the upper die operation, at this time the conversion table 20 needs to be located at the position of rotating 90° clockwise. The magazine plate 42 moves along the guide rail 43, and after one die standby position 421 loaded with the die to be changed 51 is aligned with the clamping frame 21, the magazine plate 42 stops moving. The upper die cylinder 45 extends outwardly, driving the upper die rod 41 to move in the direction close to the clamping frame 21, until the upper die rod 41 contacts the die to be changed 51. The upper die cylinder 45 continues to extend outwardly, and the upper die rod 41 pushes the die to be changed 51 away from the magnetic block 4213, and moves in the direction close to the clamping frame 21, and the fixing rod 22 gradually contacts and cooperates with the T-shaped groove 5113. When the die to be changed is completely in the clamping frame 21, the upper die cylinder 45 stops extending outwardly. The upper die cylinder 45 retracts to reset the upper die rod 41. Then, the four clamping cylinders 232 extend synchronously, driving the clamping blocks 231 connected to the output ends of the clamping cylinders 232 to contact the sliding groove 5113 and the clamping groove 5121 on the die to be changed 51, completing the fixed clamping of the die to be changed 51. Finally, the conversion table 20 rotates 90° counterclockwise to return to the working position, and the above operation completes the upper die operation.

[0051] In summary, the wire forming die changing device provided by the present application can realize the rapid changing of the wire forming die through the two-step operation of unloading and upper die, and adapt to the forming and processing requirements of different parameter wires. Meanwhile, the present application can be connected with a control device to realize the automation of the die changing operation, and further improve the forming and processing efficiency of the wires.
