110V Hydraulic Pipe Shrinking Machine Copper Stainless Steel Aluminum Iron Tube

Pipe Shrinking Machine Stainless Steel / Copper / Aluminum / Iron Tube Expander

Features of Hydraulic Pipe Shrinking Machine:

1. Microcomputer control, hydraulic drive, manual, semi-automatic, and fully automatic operation modes can be selected arbitrarily. The footswitch has multiple functions of start and emergency stop.

2. It can be controlled by a single station, double station, three stations, and multiple stations. It can shrink and expand multiple times at the same time and use linear guides as the carrier to make it run smoothly, without wear, and with good product repeatability.

3. The double-head shrinking machine can adjust the distance between the two heads according to the length of the processed pipe.

4. Single clamping or double clamping can be selected according to the length of the pipe.

5. The steel pipe shrinking machine has the characteristics of convenient operation, stable performance, high work efficiency, and high safety factor. It is an ideal piece of equipment for the processing industry.

The technical parameters

Product Description

PS Series hydraulic automatic reduction of the machine, based on the introduction of foreign advanced technology, the company developed these new products. The machine is controlled by PLC,hydraulic driven,dialogue type operation. Electrical and hydraulic components are imported. As a result of strong memories, no contacts PLC control,The machine is of better quality, more stable, easier to operate, and do not need professional and technical personnel to complete the operation of the machine. Mobile pedal switch with start, stop, stop and quick start three functions, Higher security, manual / automatic, once / twice, flexible options. With replacement of a different mold to be completed shrink tube, flaring, Dun tendons, and other internal and external flange tube end forming production requirements, Machining shapes include concave section, long, bias, square, ramp extension, V-type, regular polygon, symmetrical polygonal openings elbow, elbow and other flat. Mold replacement faster, more convenient and easier for flexible production.

PS-38A-type reduction of the machine is a single head shrink tube holes to produce two pipes each time, greatly improving production efficiency.

Principle introduction

The main part of the machine consists of transmission mechanism, clip feeding mechanism, telectrical and hydraulic systems. .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. So that each cylinder works in a certain order with the rule of action and under the action of the mold, to achieve the purpose of forming the pipe end.

PS-A series shrink tube machine operations and processes

1,Fuel tank, oil standard of not less than 1/2 scale

2,380V power supply is turned on;

3,Press the "hydraulic start" button,ectrical work, the pump is started (note the pump rotation), Adjust the pressure: press the manual pinch, back clip, during returns do not release any of a button, Pressure gauge shows the system pressure,At this point the pressure relief valve to adjust the rotation handle, e pressure is adjusted to the desired pressure is about 10MPa,Depending on the pipe deformation resistance,Should not be too high,Avoid temperature rise and hydraulic parts to wear faster.

4.Before automatic operation, check whether the selected switch is correct, whether the reduction of stroke is correct. After the first test run, then the load operation, to ensure safety.

Safety Precautions

1,Place the machine on a fixed horizontal surface and the calibration level, the machine is stable.

2,Check the oil level before use, to keep the hydraulic oil target position in 1/2 or more.

3,Check the motor rotation, such as rotation error, please adjust the power wiring.

4,When the state machine automatically, please confirm the accuracy of the input data.

5,When the machine is operating, safety, the hands, the body, such as near the action area is prohibited.

6,People must be dedicated machine operation, and the operator should be able to reach and stand within the scope of the emergency stop button.

7,Machine must be grounded.

8,When remove mold, must turn off the power.

9,Please refuel oil regularly.

10,Keep the machine and the environment clean.

11,Not allowed to work in the dust, conductive particles and acids and other places.

    In 2001,we set up our company,Hengli.

    Zhangjiagang Hengli Technology Co.,Ltd is specialized in developing and producing  LG series and LD series cold pilger mill, straightener machine, cold drawing machine and so on.

    Cold pilger mill is our main product.We self-designed and manufactured LG30,LG60,LG90,LG120,LG180 and LG250 type series of cold pilger mill in 2003,and developed LG30HGL high-speed rolling mill (160 times/min) in domestic in 2010,so filled the domestic blank. In 20011, we developed LG10H, LG20H, LG40H, LG50H series cold pilger mills, which all adopted the leading, Rexroth servo motor control system in domestic area, and realized full automation of continuous feeding and rolling. In 2012, we developed the planet form super speed cold pilger mill LG20 and LG15 whose designed stroke is 220 times/min. Then successively developed  LG 30H, LG50H cold pilger mill with crank-shaft balance system (max stroke is 180 times/min), for old and new customers to choose. At present, we are planning to continue developing LG350, LG420 type cold pilger mill, and other specifications. 

   We win the trust from the customers by means of high quality and perfect service. The products sell both home and abroad. some products are exported to the countries in South Korea,Russia, India, Mexico,Turkey and other regions.

　We stick to firmly establish the idea that "quality first. reputation highest". We provide the excellent products、good reputation and professional service with our full enthusiasm and sincerely cooperation. It is admired as contant keeping and promising enterprise in Suzhou.

   Warmly welcome to our company for visit and instruction from home and abroad.
