Description

Technical Field

[0001] The invention relates to the technical field of chains, in particular to a chain for a turning machine. Background Art

[0002] The side bending conveyor chain with a pitch of 15.875mm currently used in the existing turning machine equipment has an attached plate on which secondary accessories can be installed, and is mainly used to convey materials. The inner and outer chain plates of this chain are in the shape of "∞", with an attached plate for every 6 sections. The outer diameter of the roller is smaller than the height of the inner and outer chain plates. During transmission, it slides and rubs against the track on the turning machine equipment, causing loud noise and easy wear. At the same time, the inner and outer chain plates of the chain are in the shape of "∞", with low fatigue strength and easy to tear when subjected to force. The above reasons lead to a low service life of the chain. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0026] In this embodiment, Figure 1-3 As shown, the chain body is formed by connecting inner chain links, outer chain links, inner attached plate chain links, and outer attached plate chain links.
