The structure of the profile bending machine is an arc-shaped downward adjustment structure, with the upper roller shaft fixed and the two lower roller shafts rotating around a central axis relative to the upper roller shaft in an arc-shaped upward and downward motion. Its main function is to pre bend the ends of the profile and make the profile bend and deform. At the same time, the two lower roller shafts are also the main transmission shaft, driven by a hydraulic motor, to roll the bent and deformed profile into shape. To prevent distortion and deformation of profiles during the bending process and improve the bending accuracy of profiles, two rollers and rollers are added, which can move vertically up and down to adapt to different specifications and bending radii of profiles.

As a continuous production type profile bending machine, the profile bending machine must withstand various dynamic loads from the day it is put into production. Due to the wear and tear of the working transmission, corrosion of molten materials and decomposed gases, environmental pollution, and errors in operating methods, the working performance and efficiency of the equipment will change or slightly decrease after working for a period of time.

The daily maintenance of the profile bending machine refers to the maintenance and inspection of the profile bending machine by each production shift operator during normal production work. For example, after taking over the shift, add lubricating oil to the equipment, tighten loose nuts, and clean the oil stains on the equipment. In order to extend its service life and improve its work efficiency, the daily maintenance of the profile bending machine is very important. During its daily maintenance process, we need to pay attention to the following points:

1、 Fixation inspection of bolts and nuts

The combination of bolts and nuts is the most commonly used fixed fit method, and loosening is a fatal injury to this machine. Although properly fixed during debugging, looseness is inevitable during use. Especially in areas with high pressure or large temperature differences, loosening is more likely to occur. If there is any looseness, it should be dealt with immediately, otherwise it will cause oil leakage, center deviation, or even greater accidents. Therefore, after the machine is running, it is necessary to check the tightness of all screws again and introduce regular inspection items.

2、 Machine working centerline inspection

Mold center deviation: Causes extrusion deviation, uneven discharge, and affects product quality. Center deviation of the ingot cylinder: not only does this phenomenon occur, but it can even cause the extrusion rod to break. Center deviation of the extrusion rod: Light cases may accelerate the loss of the copper sleeve and slide rail due to uneven force, while heavy cases may tilt the robotic arm or break the extrusion rod, causing major accidents.

3、 Cleaning and lubrication

Keeping the surface of the machine clean not only ensures good appearance, but also is a part of the daily maintenance of the profile bending machine. Especially for the sliding motion part, it is necessary to pay more attention to cleaning and maintenance. If dirt adheres to the surface, it can damage the contact surface and reduce its service life.

4、 Blocking clearance

The air filter and pump suction filter screen may become clogged with dirt after long-term use. After blockage, abnormal phenomena may occur, such as failure of action, abnormal sound from the pump, etc. Once a blockage occurs, it should be dealt with immediately to avoid causing other faults.

5、 Hydraulic oil management and maintenance

Hydraulic oil is very important for extrusion machines, and hydraulic oil with excessive pollution, impurities, and improper viscosity is the bane of hydraulic components. Therefore, regular inspection, filtration, and replacement of hydraulic oil are very important things. These tasks are also part of the operating procedures for the profile bending machine. Therefore, for the profile bending machine operator, conscientiously implementing the operating procedures and operating according to the production operation sequence required by the profile bending machine means that the equipment is well maintained and maintained. Reasonable use of the bending machine can fully utilize its efficiency, maintain good working condition, and extend the service life of the machine.

The use of profile bending machines includes a series of links such as machine installation, adjustment, testing, operation, maintenance, and repair. Its use has commonalities with general machines, mainly manifested in driving motors and speed reduction and transmission devices. However, the working system of the profile bending machine, namely the extrusion system, has unique characteristics, and special attention should be paid to its characteristics when using the profile bending machine.
