[0033] The working principle and operation method of the present invention: The working process of the production line is as shown in the attached Figure 1The process is carried out in the order of arrow A. First, hang the whole bundle of round steel on the raw material feeding and advancing mechanism frame 1, untie the strapping belt, and start from the material blocking block 1-2 along the material distribution ramp 1-1; make the material dispensing transmission mechanism 1-3 move forward to drive the material dispensing block 1-4 to rotate from the preparation posture to the material dispensing posture, and dispensing the round steel material 12 from the material distribution ramp 1-1 to the material receiving body 1-5. The material dispensing transmission mechanism 1-3 moves in the reverse direction to drive the material dispensing block 1-4 to rotate from the material dispensing posture back to the preparation posture, waiting for the next action. At the same time, FY30-30B clamping pliers 1-6 lock the round steel material 12 on the material receiving body 1-5, and the material feeding and advancing mechanism 1-7 drives FY30-30B clamping pliers 1-6 to move forward to send the clamped round steel material 12 into the entrance of the raw material reforming machine 2. The FY30-30B clamp 1-6 is unlocked, and the feeding and advancing mechanism 1-7 drives the FY30-30B clamp 1-6 to work in reverse and return to the original position, waiting for the next action.

[0034] After the round steel material 12 is cold-drawn to the required size by the raw material reforming machine 2 , it freely falls into the material receiving hook 3 - 1 of the reformed material turning and delivering machine 3 .

[0035] When the flipping mechanism 3-2 is working, the material receiving hook 3-1 is lifted up to the dotted line position, and the pneumatic control system sends high-pressure gas to the inlet and outlet holes 3-2-8 of the lower chamber of the flipping power cylinder, and drives the flipping power shaft 3-2-3 to rotate forward (counterclockwise) through the flipping power arm 3-2-2 to flip the round steel material onto the material receiving body 2 3-3, and sends high-pressure gas to the inlet and outlet holes 3-2-7 of the upper chamber of the flipping power cylinder, and drives the flipping power shaft 3-2-3 to reverse (clockwise) through the flipping power connecting arm 3-2-2, so that the material receiving hook 3-1 returns to its original position and waits for the next action. At the same time, the FY30-30B clamping clamp 2 3-4 locks the round steel material 12, and the feeding and advancing mechanism 2 3-5 drives the FY30-30B clamping clamp 2 3-4 to move forward to send the clamped modified round steel material 12 into the servo sizing mechanism 3-6. At the same time, the servo sizing mechanism 3-6 starts to transport the modified round steel material 12 to a specified length into the cold cutting press cutting die in the system to cut the specified length material segment.

[0036] The cut fixed-length material segments slide freely along the ramp of the cutting die into the material segment transfer box 5, and when the box is full, it is transported to the material segment storage batching machine 6 by a forklift or a crane.

[0037] When the material section transfer box 5 opens the bottom, the fixed-length material section freely rolls down along the slope of the discharge ramp plate 6-1-1 to between the two loosening plates 6-2-3, and is throttled by the loosening mechanism 6-2. The loosening cylinder 6-2-1 in the loosening mechanism 6-2 alternately supplies high-pressure gas to the upper and lower inlet and outlet holes of the cylinder by the pneumatic control system, drives the loosening connecting rod 6-2-2, and drives the upper loosening plate 6-2-3 to move forward and backward along the discharge ramp plate 6-1-1. The forward movement rolls the fixed-length material section to the pushing area of ​​the pushing mechanism 6-3; the pushing cylinder 6-3-1 in the pushing mechanism 6-3 enters the high-pressure gas through the inlet and outlet holes 6-3-5 of the front cavity of the pushing cylinder, and the piston rod drives the pushing and pulling plate 6-3-2 to move leftward along the two pushing guide rods 6-3-3, pushing the fixed-length material section to the waiting area 6-4. When high pressure gas enters the inlet and outlet holes 6-3-4 of the rear cavity of the push cylinder, the push plate 6-3-2 returns to its original position and waits for the next work.

[0038] The first robot workstation 8 grabs the fixed-length material section through the pneumatic gripper mechanism 8-1 and sends it to the cold forging die of the cold heading forging machine 7. The robot workstation 8 returns to the original position and waits. The cold heading forging machine 7 moves once, forging the middle round table, and then returns to the original position and waits. The second robot workstation 8 grabs the forged semi-finished product through the pneumatic gripper mechanism 8-1 and sends it to the M24 thread rolling machine 9 to roll the M24 thread. After the M24 thread is rolled, the third robot workstation 8 grabs the rolled semi-finished product through the pneumatic gripper mechanism 8-1 and sends it to the M25.6×6 special thread rolling machine 10 to roll the M25.6×6 special thread. After the M25.6×6 special thread is rolled, the fourth robot workstation 8 grabs the rolled finished spiral spike through the pneumatic gripper mechanism 8-1 and sends it to the hot degreasing furnace 11 for degreasing to complete the processing task.
