When one end of the wire rod is against the positioning block 6, the follower frame 5 can follow the movement. A cutter 7 is installed on the follower frame 5. After the cutter 7 cuts the wire rod, the wire rod can be unloaded by rotating the positioning block 6.

[0031] The process of straightening and cutting the wire rod by this device is as follows: one end of the wire rod passes through the two limiting rollers 2 and extends into the first driver 4. The rotation of the first driver 4 allows the wire rod to be loaded. After being straightened by the straightener 3, the wire rod can enter the second driver 4. The second driver 4 allows the wire rod to pass through the cutter 7 and hit the positioning block 6. The positioning block 6 can drive the follower frame 5 to move with the movement of the wire rod, and then the wire rod is cut by the cutter 7. After the wire rod is cut, the positioning block 6 can be rotated, and then the wire rod can be avoided, so that the wire rod can be unloaded. During the cutting process, when the cut part of the wire rod hits the cutting part of the cutter 7, the cutter 7, the follower frame 5, and the positioning block 6 can continue to move backward. After the cutter 7 cuts the wire rod and returns to its position, that is, when the cutting part of the cutter 7 is separated from the wire rod, the wire rod can pass between the cutters 7 at this time, and then the follower frame 5 returns to its original position, positions the wire rod through the positioning block 6, and continues to unload the wire rod.

When the square frame 31 rotates, it can drive multiple straightening wheels 32 to rotate on the outside of the wire rod, and then the wire rod can be straightened.

[0040] Refer to the instruction manual Figure 1 , Instruction Manual Figure 4 , Instruction Manual Figure 5 , Instruction Manual Figure 6 and instructions attached Figure 9 The follower frame 5 includes a mobile frame 40 located above the supporting frame 1, and guide cylinders 41 are installed on both sides of the lower end of the mobile frame 40. A guide rod 42 is provided in the guide cylinder 41, and the guide rod 42 is installed on the supporting frame 1 through a support block 43. A return spring 44 is sleeved on the outer side of the guide rod 42, and the return spring 44 is located on one side of the guide cylinder 41. A square adjusting rod 45 is installed on one side of the upper end of the mobile frame 40, and the positioning block 6 is installed on the square adjusting rod 45 through a bolt connection.

[0041] The process of the follower frame 5 following the movement of the wire rod is as follows; when one end of the wire rod is against the positioning block 6, the positioning block 6 can drive the square adjusting rod 45 and the movable frame 40 to move, and the moving direction of the movable frame 40 can be ensured by the guide cylinder 41 and the guide rod 42. When the movable frame 40 moves, the return spring 44 can be compressed. During the cutting process, when the cut part of the wire rod is against the cutting part of the cutter 7, the cutter 7, the follower frame 5, and the positioning block 6 can continue to move toward the rear side. After the cutter 7 cuts the wire rod and returns to its position, that is, when the cut part of the cutter 7 is separated from the wire rod, the wire rod can pass through between the cutters 7, and then the movable frame 40 can be pushed back to its original position under the elastic force of the return spring 44.

[0043] The process of positioning the wire rod by the positioning block 6 is as follows: the square moving block 46 is moved on the square adjusting rod 45 through the square hole 47. After moving to the specified position, the limit screw 49 is connected to the threaded hole 48 through a thread, and then one end of the limit screw 49 is pressed against the square adjusting rod 45. Then the square moving block 46 can be positioned. Under normal circumstances, the blanking spring 53 is in a compressed state. The blanking spring 53 can push one end of the T-shaped rotating block 52 downward and move the other end of the T-shaped rotating block 52 upward. When the T-shaped rotating block After the other end of 52 is against the limit rod 54, it can stop rotating and press one end of the wire rod against the lower end of the T-shaped rotating block 52. When the wire rod is cut, the end of the wire rod close to the cutter 7 can be moved downward, and the end of the wire rod close to the T-shaped rotating block 52 can be rotated upward. Then the blanking spring 53 can be compressed, which will cause the wire rod to be placed at an angle, and then the wire rod can be dropped. When the wire rod drops, the elastic force of the blanking spring 53 can make the T-shaped rotating block 52 rotate back to its original position, and then it can be positioned by the limit rod 54.

[0045] The process of starting the cutter 7 is as follows: when the wire rod moves in the direction close to the T-shaped rotating block 52, the wire rod can be moved to the starter 58 first. After the starter 58 is pressed, the hydraulic cylinder 55 can be started to retract once. When the hydraulic cylinder 55 is extended, the cutting upper die 56 can be moved downward, and the wire rod can be cut by cooperating with the cutting upper die 56 and the cutting lower die 57. When the cutting upper die 56 moves downward, the wire rod can be cut. At this time, one end of the wire rod is against the cutting upper die 56, and the cutting upper die 56 can be pushed backward together with the entire cutter 7, the follower frame 5, and the positioning block 6. At this time, the return spring 44 can be further compressed, and then the hydraulic cylinder 55 is shortened, which can make the cutting upper die 56 move upward. When the wire rod is separated from the cutting upper die 56, the cutter 7, the follower frame 5, and the positioning block 6 return to their original position under the elastic force of the return spring 44.

When the wire rod contacts the telescopic rod 61, the telescopic rod 61 can be pushed backward and the rear side of the telescopic rod 61 can contact the T-shaped rotating block 52. When the telescopic rod 61 moves backward, the pushing rod 63 can press the starting switch 59. After the starting switch 59 is pressed, the hydraulic cylinder 55 can be extended and retracted once.

[0047] The process of pressing the starter 58 is as follows: when the wire rod moves toward the direction close to the starter 58, the wire rod can first contact the telescopic rod 61, the telescopic rod 61 can compress the connecting spring 62 and push the push rod 63. When the push rod 63 and the start switch 59 are pressed, the hydraulic cylinder 55 can be started, and then the limit platform 60 can be pushed through the push rod 63. The limit cylinder 60 can push the T-shaped rotating block 52 and move the movable frame 40.
