Copper tube expanding machine

I. Structure and working principle of copper pipe expander: The pump station is composed of multi-stage pumps: 2 sets of working pumps for the equipment of the first to the third specifications, and 1 set of working pumps for the equipment of the fourth to the seventh specifications. A no-load fast-forward and fast-back pump is set.The copper tube expanding machine is a double cylinder parallel and uniform pushing hydraulic pushing machine. The pump station adopts the form of integrated connection, which is easy to maintain.Pump station oil tank is divided into two parts, the main and the auxiliary oil tank is designed for the cleaning of the filter. When cleaning the filter, the connecting raft door of the main and the auxiliary oil tank is closed, the hydraulic oil of the auxiliary oil tank is released, and the oil inlet of the oil pump is opened.Take out the filter, clean the filter with gasoline or diesel oil, and put it back as it is.

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.

A, host,

1. Fuselage: composed of upper beam, movable beam and worktable column, etc.The movable beam is driven by the cylinder through the eight guide sleeves on the column sliding, to achieve a variety of actions.2. Main cylinder: it is the original part of the action of the equipment. All the sealing rings inside it have good wear resistance and long service life.3, limit device

Two, power station: mainly by the oil tank, oil pump, motor and valve integration

The hydraulic pipe expander is mainly composed of the base, the motor cone punch, the chuck and the hydraulic system, etc. The six stroke switches are hit by the cylinder downward in turn: fast down, work forward, fast forward, work forward, work backward and fast backward, and the six movements are used as one work back and forth.
