Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for chain production, in particular to a pin riveting tooling die.

Background Art

[0002] A chain is generally a metal link or ring, mostly used for mechanical transmission. Most chains are composed of chain plates, chain pins, bushings and other components. The chain is mainly used for mechanical transmission and has to bear a large frictional force. The assembled structure of the chain is that the chain plates are sleeved on the chain pins, and the bushings play a supporting role for the chain plates. During the assembly process, riveting operation needs to be carried out on one side of the chain pin to prevent the chain plates from falling off the chain pins and damaging the use of the chain.

[0003] In the existing technology, the manual alignment during the riveting process of the chain pins affects the corresponding production efficiency, and the production potential of the production line cannot be released all the time. It can only be semi-automated, which requires a large amount of manpower and results in low production efficiency.

Screws are provided at the upper ends of the upper limit plate supports, and fixing nuts for pressing the upper limit plate are provided on the screws. Waist-shaped holes corresponding to and cooperating with the screws are provided on the upper limit plate.

[0007] Preferably, an insert sleeve is provided at the lower end of the concave die, and a backing plate is provided between the insert sleeve and the base.
