Description

Technical Field

[0001] The invention relates to the technical field of belt tensioner housing processing, in particular to a trimming die for an automobile belt tensioner housing. Background Art

[0002] The tensioner is mainly composed of a fixed shell, a tensioning arm, a wheel body, a torsion spring, a rolling bearing and a spring sleeve. It can automatically adjust the tensioning force according to the different tightness of the belt to make the transmission system stable, safe and reliable.

[0003] The tensioner is a vulnerable part of automobile parts. The belt is prone to wear after a long time of use. The belt groove will appear to be stretched after being deepened and narrowed. The tensioner can be automatically adjusted according to the degree of belt wear through the hydraulic unit or damping spring. In addition, the tensioner can make the belt run more smoothly, with less noise, and prevent slipping.

[0004] The tensioner is a routine maintenance item and needs to be replaced after 60,000-80,000 kilometers. If there is an abnormal whistling sound from the front end of the engine or the tension mark of the tensioner is too far away from the center, it means that the tension is insufficient. After 60,000-80,000 kilometers (or when there is an abnormal sound from the front end accessory system), it is recommended to replace the belt, tensioner, idler, generator one-way wheel, etc.

[0005] At present, when the existing trimming mold trims the tensioner, since the tensioner is set as a cylindrical structure, it is difficult to position it during cutting due to its smooth side, thus affecting the cutting flatness. Summary of the invention
