Analyze the solution of the cold heading machine in use damage

Because the cold heading machine is produced continuously under heavy load, and the degree of automation is high, and the movement of the structure is mostly controlled by the crankshaft or cam to make periodic reciprocating motion or rocking, resulting in the force and impact caused by the acceleration. The impact is very large, and the organization of the cold heading machine and the selection of the primary part of the data are still incomplete, and thus, it is simply damaged in use.

Some improvements have been made to the cold heading machine in the practice of production and maintenance. Improvement of the main transmission part Regarding the upsetting speed of the cold heading machine, the output rate per minute of the large large-scale cold heading machine (the diameter of the screw shaft is more than 10 mm) is 60 to 70 pieces per minute (refer to double-clicking the cold heading machine), the stroke of the slider The number of times is 120 to 140 beats / min. According to the requirements of the cold heading process, the initial speed is between 0.4 and 1 m/s.

Because the cold and tender machine is under heavy load, the quick cover is produced, and the degree of automation is high, and the tissue movement is mostly controlled by the crankshaft or the convex transmission to make a periodic reciprocating motion or sway, resulting in the force caused by the acceleration. And the impact force is very large, and the organization of the cold heading machine and the selection of the primary parts of the data are not perfect, and thus, it is simply damaged in the application.
