Works Introduction:


The machine consists of main transmission mechanism, mandrel body, top feed mechanism, the clip feeding mechanism, electrical systems and hydraulic systems as its main components. .While working, the machine is rotated by a motor driven pump, to supply pressure oil, together with orders given from PLC to control each solenoid valve turned on and off , So that each cylinder takes action in a certain order and regularity to bend the pipes.

The main components and major mechanical components:


1 The machine is mainly made from high quality steel plate welded structure with high strength and stiffness.

2 The main structure is scrub by rusting is painted with rust.

3 The touch screen is a 10.4 in. screen from Taiwan origin Hightech Co., Ltd

4 Adopts imported Delta PLC program maker and servo drives,servo motors are from Japan's Mitsubishi and Taiwan Delta,with good Compact, high precision and long life.

5 Proximity switches and encoders are Japan’s OMRON, NEMICOM with stable performance.

6 Pump and solenoid valve are from Taiwan's famous brand "Dawn hydraulic" and "hydraulic Asada", which have have a clear visual display for oil level.


Main mechanical functions:

1 Programming and inputs are carried out directly on the interactive touch screen, all messages can be displayed in Chinese.

2 Programs and data have password protection.

3 Corner and feeding motor servo control.

4 Mechanical control system has processed counting function and fault self-diagnosis function.

5 Machinery with safety protection and emergency stop protection.


Random factory documents and information:

1 1 Product certification

2 1 Instructions

            3 a set of distribution ring

4 an allen wrench set.

5 Mould drawings (provided by contract).


Installation, commissioning, training, after-sales service

1,Installation and acceptance

1.1 After the machinery from the supply side to the demand side, the demand side is responsible for unloading facility.

           1.2  Supplier is responsible for the mechanical commissioning.

1.3Demand side should accept the machine after bending specimens according to demand’s request (subject to the requirements of the contract)


Train to all the adjustment workers, operators, maintenance workers (hydraulic, pneumatic lubrication system maintenance personnel, electrical, electronic and control systems personnel, CNC programmers, technical staff),to make sure they can operate, adjust, repair, programming properly.


3.1 Quality "three guarantees" period: 12 months form the commissioning date of acceptance by the demand side

3.2 During the "three guarantees" period of equipment failure, the supplier is responsible for free repair, replacement parts (except for the demand side in violation of the rules of accidental damage caused).

3.3 Responding to the supplier to provide services required by the buyer receives telephone (fax) the day after, within 48 hours (except holidays) sent to the demand-side scene.
