G800 Hydraulic Pipe Shrinking Machine 3 Cylinder Shrink Wrap Machine

Where is the Pipe Shrinking Machine Mainly Used?

The pipe shrinking machine is mainly used in construction sites. Iron pipes, square pipes, round pipes, galvanized pipes, stainless steel pipes for reducing diameter and neck expansion are ideal pipe end forming equipment. The steel tube shrinking machine is suitable for all kinds of mechanical high and low-pressure oil pipes, air pipes, water pipes, cable joints, automobile air conditioning pipes, automobile power steering pipes, engine oil pipes, gasoline oil supply pipes, as well as construction accessories, daily hot water pipes. Used in industries such as vehicles, engineering machinery, hydraulic machinery, welding, and cutting equipment. The specifications of the shrinking machine required by different projects are different.

Operating Instructions:

G400 pipe-shrinking machine operations and processes

1. Take out the mould by rotating it according to arrow direction, no reverse rotation allowed.

2. Moulds can be changed according to different specifications.

3. Head length can be adjusted by middle adjusting rod, loose the belt wheel screw, adjust the length and fasted the screw again.

4. Pour in 80% diesel and 20% engine oil, as the oil pump capacity is big, oil box entrance valve should be fully open, machine valve fix a little oil is ok.

5. After the umbrella-block wear down and the gap becomes big, you can put a gasket between umbrella block and the mould, but the gasket can not be too thick so that machine won't get stuck.

6. The lubrication oil should be changed after it gets dirty.

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.

Part of the machine:

    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.
