Product Advantages

I, Features and advantages of Hydraulic cold pipe bending machine.

The hydraulic cylinder of cold pipe bender was optimized by big data. In order to shorten the bending speed of cold pipe bending machine, the working stroke of hydraulic cylinder is calculated accurately, and the bending speed is improved obviously. In theoretical experiments, 10% time can be saved when the cold-formed pipe is bent about 10°. Improve work efficiency.

1, In order to improve the bending speed, special Italy imported large flow (about 400 L/min) operation control valve. Extend the service life.

2, Engine, hydraulic cylinder and other components are produced by professional manufacturers at home and abroad.

II, Characteristics and advantages of Power station

Independent power station

1, The design of the power part of the integrated cold bending pipe machine is narrow. In the maintenance process of the engine, the disassembly of the oil filter and diesel filter is complicated due to the small clearance between the components. Due to the large gap between different components, the daily maintenance of independent power station is very convenient.

2, In order to provide operators with a low noise working environment, the power part is designed as an independent type, which can be far away from the main engine, and is connected with the main engine with a fast connection device. At the same time, it is convenient for cold pipe bending machine transportation.

3, The working temperature of the hydraulic oil circuit of the pipe bender equipment is between -30℃ and 50℃. The high temperature construction environment brings inconvenience to the long time construction of cold formed pipe, which is easy to cause the oil temperature rise, accelerate the aging of hydraulic components, and seriously affect the service life of equipment. The power radiator must have sufficient heat dissipation capacity. Therefore, a special radiator device is designed, the heat dissipation effect is twice that of the ordinary radiator, and the temperature sensor is installed to realize the automatic control of temperature. Ensure that the cold pipe bender can run for a long time without stopping. Improve work efficiency.

4, Install hydraulic oil preheating device

In the construction process of cold pipe bender under low temperature environment, because the temperature of hydraulic oil is low, the radiator of the engine is used to form a preheating circulation system, so that the temperature of hydraulic oil rises rapidly, the equipment preheating time increases, and the equipment enters the working state in advance.

5, Install oil suction filter and oil return filter on hydraulic mailbox of power station, and install hydraulic oil filter element cleaning and replacement alarm device. Prompt the operator to carry out maintenance work in time.

III, Characteristics and advantages of hydraulic mandrel

The hydraulic mandrel was optimized and improved. Without affecting the normal bending quality, the overall weight is reduced through shortening and optimization, and the service life of the walking mechanism is greatly extended. Improve work efficiency.

Major Component

The hydraulic cold pipe bending machine is mainly composed of outer bracket, lower die, positioning seat, wedge block, hydraulic cylinder, pipe bender, pipe hosting frame, power station and so on.

1, The main hydraulic power source adopts Deutz engine, hydraulic pump and hydraulic motor, which are HUADE brand well-known in China.
2, The operating mechanism adopts assembly parts imported from Italy, which is light and flexible in operation and accurate in control, thus ensuring the accurate bend of the steel pipe
3, The mandrel adopts full hydraulic control, double-angle steel wedge structure, and soft structure externally to effectively ensure that the inner anticorrosion layer of the steel pipe is not damaged. Its working principle is to use its wedge face and hydraulic drive to make it up quickly and meet the requirements of bending steel pipe. The walking part of the mandrel is to use the auxiliary hydraulic power to drive the hydraulic motor to ensure the smooth walking of the tire core in the steel pipe.
4, The hydraulic cold pipe machine provided by our company refers to the advantages of similar products at home and abroad, with
reasonable design, compact structure, controllability and high work efficiency. It is an essential tool for the processing and production of cold pipe bending of large pipelines.
5, The whole machine adopts high quality power equipment and hydraulic drive device, which has excellent performance, reliable quality and can adapt to harsh construction conditions.
