Operation Manual of W24S Hydraulic Profile Bending Machine

1. Hydraulic profile bending machine Usage

W24S series rolling machine is hydraulic 3 roller profile bending machine, which mainly uses in various steel profile bending.

It can roll “O” spiral shape workpieces. It is widely in petrol, chemical, shipyard, metalworking and machine manufacturing industries.

2. Main Technical Data

Here are the drawings:

Technical Specifications

Model and specification

Please find the right model according to the maximum bending resistant modulus of profiles.

3. The main structure and working principle of hydraulic profile bending machine

W24S profile bending machine consists of machine body, side roller part, support roller part, electrical system, and hydraulic system.

The machine body is a whole welded structure, the left and right running arms are installed in machine body, which droved by two hydraulic pumps, and do arc up and down movements.

Support rollers are installed on two head of machine body, which can turn to various angles to suit for kinds of profile bending.

4. Drive system

The main drive system is consist of motor driven the reducer, then transit to the side rollers, and then pass to the up roller.

5. Function, working process and working field

  • Machine function

Three rollers are main driven, can do the pre-bending, through adjusting the guide rollers, it is easy to correct the deformation from the bending process.

  • Working process

It can do pre-bending, and its process is shown as following:

Working process of hydraulic profile bending machine

  • Working field

The main parameters on form mean the max. bending capacity with best working efficiency. If other steel profile like the square, angle, only if the bending-resistant modulus less than 45 cm3, then it is available to finish bending on this W24S-45.

  • Bending way

6. Hydraulic system

The hydraulic system pressure relief valve by an electromagnetic build.

The rise and fall while roller cylinder through two solenoid valve lift on both sides of the roller cylinder when the electromagnetic relief valve must have electricity and build pressure on the system.

When the YV01 and YV1 get electricity when the tank rolls up the left side, as YV01, and YV2 get electricity when the tank rolls down the left, the right roll rise and fall similar to the left.

The system’s working fluid for the 30 # -40 # ordinary hydraulic oil, motor rotation should be checked before testing to correct, to observe the fluid level to allow the second fuel tank.

Should be checked once every six months, the extent of oil deterioration or replacement of the new oil, oil temperature is less than 70 ° C.

7. Electrical system

  • W24S-45 uses 380V/50HZ/3PH electricity.

8.Installation and commissioning of hydraulic profile bending machine

8.1 Installing

We packed the machine as a whole in steel carton. When arriving in client’s part, please check the correspondence of packing list and real machine. Before debugging, please inject oil to machine.

8.2 Debugging

8.2.1 Preparation before debugging

Please check all connects and clamping parts.

Please check the hydraulic oil level, and check if the lubrication is okay.

Please check the voltage of electricity.

8.2.2 Run without loading

After check above all, please run the main drive and do up and down movements, take 15 minutes as a cycle.

Check the and adjust the up roller and sides rollers, to make the distance is suitable and workable.

8.2.3 test requirements

Movements should be smooth on both sides of roll

Roller rotation and lift should be flexible

All Transmission Parts should be no abnormal noise

All fasteners are not allowed loose, well-oiled machine

Bearing temperature should not exceed 35 ° C, the highest temperature should not exceed 70 ° C, bearing the temperature should not exceed 40 ° C, the highest temperature should not exceed 70 ° C, the hydraulic pump oil temperature should not exceed 60 ° C.

8.2.4 Load test

No-load test to normal only after the load test. The general procedure is as follows:

Basic parameters in the table according to the provisions of the relevant profile parameters expected, pre-bend sections of the treated end.

On an operational proficiency score of sub-volumes into the provisions of the diameter of round workpieces.

8.2.5 Load test requirements

Load testing should meet the basic parameters of the relevant performance requirements.

Load and load operation process, the transmission system should be stable,  the impact of no abnormal noise, working system, the operating system should be flexible, accurate and reliable, the bearing temperature must not exceed the above requirements.

The process of rolling the die and the profiles there is no slipping between the phenomenon.

9. Operation rules and safety maintenance of hydraulic profile bending machine

9.1 Preparation and inspection before use

Before using please read this note to understand the aircraft’s technical performance and operational methods, in strict accordance with the safe operation of the system and in accordance with the requirements of Article 8.2.1 to prepare the work, and the removal of roll profiles oxide, while grinding edge, bulldozing weld.

9.2 Safety and Protection

Using the machine, please pay great attention to the following safety matters.

Work overload is strictly prohibited.

The use of the process, if found to have irregular noise, the impact should be immediately stopped checking.

The use of the process should always check that the transmission mechanism of the joints and maintain no loose, no damage.

9.3 Operation way

According to profile dimensions will be reduced to a certain height on both sides of roll.

The profiles will be processed and sent on both sides of the roller between the roller.

Process volume by round, until it meets the requirements date.

Main drive is stopped, lowered edge roller, may remove the workpiece.

9.4 Machine lubrication
Reasonable machine lubrication is to reduce power consumption and increase machine life and effective measures to this, we must choose the right lubricants, to establish the necessary lubrication system.

9.4.1 Lubrication
The machine according to the work of cups was used lubricating oils, artificial fuel, lubricating oil tank focused on three ways.

9.4.2 Lubricant Selection
Artificial refueling Department, the use of calcium-based grease, oil cup lubrication points, the summer use of calcium-based # 2 grease, the winter using a # calcium-based grease.

9.4.3 Lubrication system and note
The user according to the specific situation of the machine, load and operation of the establishment of a specific lubrication system.

The machine before starting the lubrication points must be sufficient oil supply.

The machine in a continuous working condition, the oil cup oil in general 4 hours once a month in general lubricating the gears once.
Machine washed once a year the whole lubrication system.

10. The lifting of machine tool & maintenance

The proper use and reasonable maintenance and repair, not only can prolong the life of the machine, but also reduce the cost of repairs. The aircraft maintenance and maintenance of the following main points:

10.1 The machine must be running normal and well-oiled circumstances for work, they should strictly enforce the lubrication system.

10.2 During roll profiles, we should promptly remove the oxidation profiles between the skin and die.

10.3 The vulnerability of the timely replacement of worn parts and the loss of too many performance requirements of the original parts.

10.4 Regular maintenance of the electrical system, dust, and timely replacement of failed components.

10.5 In the machine is running, should pay attention to a movement parts of the temperature does not exceed the prescribed limits.
