Description

Technical Field

[0002] A three-wheeled motorcycle edging sleeve is a square metal sleeve used on the chassis of a three-wheeled motorcycle to edge the square tubes on the chassis of the three-wheeled motorcycle. It is made by stamping and bending a metal sheet. Currently, when stamping and manufacturing the three-wheeled motorcycle edging sleeve, it is necessary to first cut a metal sheet of the desired shape and specification from the metal sheet, and then use different stamping dies to bend the metal sheet 90 degrees on both sides of the edge and both sides of the middle. During the operation, each stamping needs to be performed on a different stamping die. Frequent replacement of stamping dies is not only cumbersome to operate and inefficient in production, but also requires more manpower input, increasing production costs. Therefore, how to solve the current problem of cumbersome operation and low production efficiency caused by the need to use a different stamping die each time when stamping the three-wheeled motorcycle edging sleeve has become a long-standing technical problem that has been difficult to solve.

[0003] In view of the above reasons, an operating method of a continuous three-step stamping die device for an edge cover of a three-wheeled motorcycle is developed. Summary of the Invention

The device can synchronously complete the three-step stamping processes of stamping, first bending and second bending of the metal sheet through the buckling of the upper die base and the lower die base. After the edging sleeve is made, the edging sleeve can be separated from the stamping die through the material return cylinder and the material return top plate without excessive intervention from workers, effectively ensuring the continuity of each process, greatly improving production efficiency, saving workers' physical strength and labor, and reducing production costs. It effectively solves the current problem of cumbersome operation and low production efficiency in the stamping production of the edging sleeve of a three-wheeled motorcycle, which requires each stamping to be performed on a different stamping die.
