Knurled vertical grain cold punched nuts

Guangdong Yueluo Hardware Industry Co., Ltd. provides a kind of rivet, parts and parts are riveted by the rivet, the part has a fixed plate and a fixed plate, and the part is located between the fixed plate and the fixed plate, The rivet includes a nail head, a nail post and a nail post which are connected in sequence, the diameter of the nail post is larger than the diameter of the nail post, the nail head is matched with the outer end surface of the fixing plate, and the length of the nail post is It is greater than the sum of the riveting length of the fixing plate and the riveting length of the part. The rivet can control the distance between the parts, so that the relative rotation of the two parts is more smooth and easy to operate.


Usually, the pumped storage unit adjusts the opening of the guide vane through the movable guide vane to control the power generation output and the pumping head of the unit. The torque of the guide vane rotation depends on the relay to act on the control ring, and the torque is transmitted to the guide vane rotating shaft through the connecting rod and the arm. The torque transmission between the crank arm and the rotating shaft all acts on the pin located between them. When the unit is overhauled, it is necessary to remove the pin between the arm and the rotating shaft of the guide vane in advance when it comes to the replacement of the guide vane. However, due to the special position of the pin and the limited inspection space, the conventional method is not only time-consuming and laborious, but also has the risk of damaging the pin. Maintenance work brings inconvenience.
