1. What is a metal profile bending machine?

Metal Profile Rolling Machine For Sale


Metal profile bending machine is also called profile rolling machine, profile steel bending machine, angle steel rounding machine, flange machine, etc. The profile metal bending machine can be used for rolling profiles of various specifications, such as angle steel, channel steel, H-beam, flat steel, round tube, square tube, rectangular tube and other special profiles. End pre-bending and bending can be completed in one feeding.


The profile rolling bending machine is divided into two types: horizontal type and vertical type. According to different shaft arrangements, it can also be divided into up-adjustment type and down-adjustment type. Different molds can be customized according to user requirements.



The metal profile rolling machine is used to roll carbon steel, stainless steel, non-ferrous metal profiles, angle steel, strip steel, channel steel, pipes, etc. into diameters φ 320- φ An efficient rounding device for 6000mm circular rings and flanges.


The profile roll bender machine has the advantages of small size, low energy consumption, high efficiency, no noise, convenient installation and use, simple operation, strong load-bearing capacity, long service life, and fast rolling speed.


2. How to operate profile rolling machines correctly?

operate profile rolling machines

When operating sheet profile rolling machines, the staff should strictly follow the operating procedures to carry out the correct operation:

Operators must be familiar with all switch and button functions of this equipment. Before starting the machine, each adjusting screw and control switch must be checked to ensure their normal function.

Operators must tie their clothes and cuffs tightly, and it is strictly prohibited to tie aprons or noodles for operation; Long haired female workers should curl their hair and wear a hat when working to prevent safety accidents from being twisted in.

Before starting the metal profile bending machine, add an appropriate amount of lubricating grease to each transmission and sliding surface. Only after the equipment operates normally, flexibly, and reliably can the next step of operation be carried out.

Before starting the bending machine, check the strength and accuracy of the mold and mold base to ensure they meet the requirements.

Adjust the position of the roller according to the diameter of the coil. Conduct debugging before homework.

The transmission part should be equipped with a protective cover. During operation, dismantling is strictly prohibited.

The diameter specifications of the processed parts should not exceed the allowable range.

The operation should be carried out with no load and confirmed to be normal before proceeding.

When feeding the coil, it should be pushed forward at a uniform speed.

When processing circular plates without central holes, appropriate safety measures should be taken.

If any abnormalities are found during the operation, the machine should be immediately shut down for inspection, and the operation can only continue after the faults are eliminated.

During operation, non operating and auxiliary personnel are not allowed to stay and watch around the machinery.

The processed workpiece should be placed on the floor or material cart and neatly stacked.

After the operation, the power should be cut off, the leftover materials around the machine should be cleaned, and the daily maintenance work of the machine should be done well.


2. Four common faults and measures of profile bending machines

During long-term use of the metal profile bending machine, various failures may occur. Here are some common failures and how to deal with them:


1) Profiles cannot enter the bending machine

Possible Causes:

- Entry channel blocked

- Not enough pressure

- Loose or broken moving chain



- Clear access

- Check pressure source and drive chain

- Readjustment Metal Profile Bending Machine


2) Inaccurate or deformed bending angle

Possible Causes:

- The mold is not suitable

- Uneven material

- Tool wear or damage



- Replace the appropriate mold

- Check material quality

- Replace or repair mold


3) The bending machine is overheated or poorly cooled

Possible Causes:

- Hydraulic system failure

- Cooling system failure



- Check the working status of hydraulic system and cooling system

- Repair fault


4) The noise of the profile bending machine is too loud

Possible Causes:

- Bearing wear

- Drive chain is loose

- The equipment structure is unreasonable



- Replace bearings

- Check drive chain

- Adjust equipment structure
