P3Z1-125 electric tube expander machine

P3Z1-125 electric tube expander machine

Purpose: This machine is suitable for the expansion processing between different materials (copper, steel, aluminum, titanium and other alloy steel and stainless steel) different pipe diameters (10-102 wall thickness 1mm-6mm) and thick and thin orifice plates. The pipe and orifice can be expanded automatically, and the expansion rate can be controlled.

Working principle: P3Z1 series electric tube expander is used for the tight expansion of the tube port and tube plate in the manufacture of pressure vessels and various types of heat exchange equipment, as well as any work occasions that need to expand the tube port, involving the manufacture of heat exchangers in chemical and petrochemical industries, boiler installation and manufacturing, power plant condenser, central air conditioning, drying equipment manufacturing and other industries. The electric tube expanding machine is composed of a tube expanding machine and a digital display control instrument, and a tube expanding machine (working head) is matched with it. The main working principle is that when the electric tube expander drives the tube expander plugged into the tube hole to rotate clockwise, because there is a certain rotation Angle between the expansion bead of the tube expander and the tube, the tube expander moves forward along the axis of the tube while rotating. In addition, the tube expander is thin in front and thick in back, so that the expanded tube is gradually expanded in the rolling of the expansion bead and closely connected with the hole wall of the tube plate. In the process of tube expansion, with the continuous expansion of the tube expander, the rotation provided by the tube expander also increases, and the motor current of the tube expander also increases. After sampling the current of the digital controller and amplifying the analog-to-digital conversion, the digital display of the actual working current is made. After the comparison between the comparator and the pre-set expansion value, the controller controls the motor to stop automatically when it reaches the set value. After the delay interval of the delay circuit, the controller automatically drives the tube expander to reverse counterclockwise, so that the tube expander begins to loosen. When the release time reaches the pre-set exit time, the controller disconnects the motor power supply of the tube expanding machine, and the tube expanding machine stops, thus completing a tube expanding process.

In actual use, the tube can be expanded in batch by adjusting the set value of the expansion tube and its exit time. And it can ensure that the expansion rate of all tube heads (expansion degree) is completely consistent.

P3Z1 electric tube expander has more than eight specifications to choose from depending on the diameter of the tube being expanded. Welcome customers to inquire according to actual needs.
