    Equipment details

    Copper tube expanding machine

    1. Structure and working principle of copper tube expanding machine: the pump station is composed of multi-stage pumps: two working pumps for equipment of the first to the third specifications, one working pump for equipment of the fourth to the seventh specifications, and one no-load fast-forward and fast-retreat pump of the first stage.Copper tube expanding machine is a double cylinder parallel and uniform speed hydraulic pusher, the pump station adopts the form of integrated connection, the maintenance is simple.The oil tank of the pump station is divided into two parts, the auxiliary oil tank is designed for the cleaning of the filter. When cleaning the filter, close the connecting raft door of the main and auxiliary oil tank, release the hydraulic oil of the auxiliary oil tank, and disassemble the oil pump to feed oil and send oil.Take out the filter, with gasoline or diesel to clean the filter, the original can be installed back.

     

    Second, the working principle of copper tube expanding machine equipment: raw materials will be prepared steel pipe set in the expansion pipe mould core head, add the medium frequency induction hot line trap at the end of raw material of steel pipe and expanding mold core head, fixed expansion pipe mould core head tie rod end, open the cooling water pump, open the medium frequency power supply, the raw materials are heated to 800 ℃ and the expanding die for steel tube, open push system machine can start push the expansion pipe.
