[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1, referring to Figure 1-3An adjustable pin-type cold heading machine includes a machine body 1 and a cold heading head 15. The cold heading head 15 is provided at one end of the machine body 1. A U-shaped groove 3 is provided at the feeding end of the cold heading head 15 and at the top of the machine body 1. A first U-shaped plate 7 and a second U-shaped plate 8 are provided at the top of the machine body 1 and outside the U-shaped groove 3. The first U-shaped plate 7 is close to the feeding end of the cold heading head 15. A clamping component is installed on the inner side of the first U-shaped plate 7. A pressing component is provided inside the second U-shaped plate 8. A PLC controller 14 is installed on one side of the top of the machine body 1.

[0018] The clamping assembly includes two first electric push rods 5, which are respectively fixed to the inner walls of opposite sides of the vertical sections on both sides of the first U-shaped plate 7. Each of the two first electric push rods 5 has a clamping plate 6 connected to its opposite end.

[0019] The bottom ends of both clamps 6 abut against the upper surface of the horizontal section of the U-shaped groove 3.

[0020] The pressing assembly includes a second electric push rod 4 fixed to the lower end of the horizontal section of the second U-shaped plate 8. The lower end of the second electric push rod 4 is connected to a pressure plate 12. A pressure roller 11 is installed at the bottom end of the pressure plate 12. Guide rods 13 are provided on both sides of the upper end of the machine body 1 and on both sides of the U-shaped groove 3. The two ends of the pressure plate 12 are slidably sleeved on the two guide rods 13 respectively.

[0021] Pressure sensors 10 are installed at the connection between the lower end of the second electric push rod 4 and the pressure plate 12. Both the pressure sensors 10 and the second electric push rod 4 are electrically connected to the PLC controller 14.

[0022] A support base 9 is installed on the top of the side wall of the body 1, and a support wheel 2 is provided at the top of the support base 9 and at the end of the U-shaped groove 3.

[0023] Working principle: The pin material enters the cold heading head 15 through the U-shaped groove 3. The support wheel 2 supports the pin material. The PLC controller 14 (Siemens S7-1200 model can be selected) controls the operation. The 1214C series synchronously controls the extension of two first electric push rods 5, so that the two clamping plates 6 hold the pin material in the middle of the U-shaped groove 3. The PLC controller 14 controls the extension of two second electric push rods 4, so that the second electric push rods 4 push the pressure plate 12 and pressure roller 11 to move down. The pressure roller 11 presses the pin material into the pin material, reducing the bending degree of the pin material. The pressure sensor 10 is a strain gauge sensor with an accuracy of 0.1N, which is used to monitor the pressing force in real time. According to the preset pressing force parameters, the PLC controller 14 controls the second electric push rods 4 to extend slowly, driving the pressure plate 12 and pressure roller 11 to move down. When the pressure roller 11 contacts the material, the pressure sensor 10 transmits the force data to the PLC controller 14 in real time. If the actual force is lower than the set value, the PLC controller 14 controls the second electric push rods 4 to continue to extend until the force reaches the set value and stabilizes. At this time, the extension and retraction position of the second electric push rods 4 is locked, and the pressing calibration is completed.
