4. Product use instructions
Installation Steps:
Align one end of the cylindrical pin with the hole of the connected part, and then use appropriate tools (e.g. punch and hammer, or press) to apply pressure slowly so that the cylindrical pin is gradually inserted into the hole. During the insertion process, care should be taken to keep the cylindrical pin vertical and avoid skewing it to ensure that it is evenly stressed and enters the hole smoothly.
When the cylindrical pin is completely inserted into the hole, its ends should be flush with or slightly below the surface of the connected part (according to the specific application requirements). At this point, the cylindrical pin can be slightly adjusted with the appropriate tools to make it in the right position in the hole to ensure the tightness and stability of the connection.
After the installation is complete, the connection part of the cylindrical pin is inspected to see if the cylindrical pin is installed in place, if the fit between the pin and the connected part is tight, and if there are any signs of loosening. If necessary, the reliability of the connection can be tested by applying some external force (such as tension, pressure or torque), but be careful not to exceed the rated load capacity of the cylindrical pin.
Precautions for use:
In the process of use, regularly check whether the connection part of the cylindrical pin has signs of loosening, deformation, corrosion, etc. Especially after the equipment has been subjected to vibration, shock, temperature change or long-term use, if problems are found, corresponding measures should be taken in time to repair or replace to ensure that the connection is safe and reliable. For the cylindrical pin connection in industrial equipment and important structures, it is recommended to carry out regular inspection and maintenance in accordance with the maintenance cycle of the equipment, such as cleaning the connection parts, checking the dimensional accuracy, measuring the change of aperture, etc., in order to ensure the normal operation of the equipment and the stability of the structure.
Avoid the cylindrical pin to withstand loads exceeding its rated carrying capacity. In the process of design and use, the specifications and models of the cylindrical pin should be reasonably selected according to the actual working conditions, to ensure that it can withstand the applied tensile force, pressure or shear force, and to prevent overloading leading to fracture of the pin, deformation, or damage to the connected parts, which will lead to a safety accident. At the same time, attention should be paid to avoid the use of pins in harsh environmental conditions (such as high temperature, high humidity, strong acid and alkali, etc.), so as not to affect its performance and life, if necessary, should take appropriate protective measures (such as the use of high temperature or corrosion-resistant pins of stronger material, the connection part of the protective treatment, etc.).
When storing and handling the pins, avoid collision, extrusion or friction with other hard objects to prevent the surface of the pins from being scratched, deformed or damaged, affecting its appearance and performance. Store the cylindrical pins in a dry, ventilated environment without corrosive gases and keep them properly so that they can be kept in good condition for the next use. At the same time, we should pay attention to the different specifications of the cylindrical pin classification storage, easy to find and use, to avoid confusion specifications and lead to installation errors, affecting the use of the effect and safety.
