The anti-loss rope 36 is used to prevent the locking bolt 35 from being lost.

[0048] Working principle of this utility model:

[0049] When using a cold bending forming machine to produce irregularly shaped steel components, the end of the metal strip is first inserted into the feed inlet of the cold bending forming machine. During this process, the metal strip needs to pass between the two rotating rods 25. Then, the adjusting bolt 29 is rotated counterclockwise. The counterclockwise rotation of the adjusting bolt 29 in the adjusting hole will drive the movable plate 28 and the double-sided rack 27 to move towards the adjusting hole. During the movement of the double-sided rack 27, the double-sided rack 27 will drive the two strip scrapers 26 to rotate in opposite directions through the two gears 24 and the two rotating rods 25. When the two strip scrapers 26 respectively contact the upper surface of the metal strip... After the upper and lower surfaces are finished, stop rotating the adjusting bolt 29. At this point, the cold bending forming machine can be started to process the metal strip. During the movement of the metal strip, the two strip scrapers 26 will scrape off the solid impurities on the metal strip. If there are many solid impurities on the upper surface of the metal strip, turn on the external switch of the air pump 31. The air pump 31 will deliver gas to the jet pipe 33 through the air supply pipe 32 and spray it out, thereby blowing the solid impurities away from the metal strip. This effectively avoids the occurrence of surface defects and structural damage to the metal strip due to surface impurities, and improves the quality of the produced special-shaped steel components.
