Common Problems and Solutions Encountered by Squeezing Industrial Aluminum Industry Aluminum Profiles-WJW Aluminum Supplier Aluminum

Author: WJW Aluminum Window Manufacturers

1. The squeezing temperature of the industrial aluminum profile is too low, the squeezing speed is too slow, the outlet temperature of the extrusion machine's internal profile does not reach the solid solution temperature, and it cannot play a role in solid -soluble reinforcement.

Common Problems and Solutions Encountered by Squeezing Industrial Aluminum Industry Aluminum Profiles-WJW Aluminum Supplier Aluminum 1

Solution: reasonably control the extruded temperature and extrusion speed, so that the profile temperature at the exit of the squeezing machine is kept above the minimum solid solution temperature;

Second, industrial aluminum export fans, insufficient air volume, and slow cooling speed, can not reduce industrial aluminum profiles to below 200 C in the shortest time. The thick magnesium silicate is prematurely used to reduce solid solution. Mechanical performance.

Solution: Strengthen the air -cooled conditions, condition factories can install atomized cooling devices to meet the minimum requirements of 6063 alloy cooling gradient;

3. The ingredients of the steel ingot are not qualified, and the magnesium and silicon content in the ingots do not meet the standard requirements.

Solution: Strengthen the quality management of steel ingots;

4. When the steel ingot is unevenly treated, the magnesium silicate phase precipitated in the steel ingot structure cannot be dissolved in a short period of time, resulting in insufficient solid solution and affecting product performance.

Solution: uniformly the steel ingot;

5. Improper aging process, poor thermal air circulation or incorrect installation position of the thermal power puppets, resulting in insufficient aging or too much aging.

Solution: Reasonably determine the aging process, correct the thermal power puppet, and correctly place industrial aluminum profiles to ensure that the hot air circulation is smooth.

GB/T1497-1988 Industrial Aluminum profile processing operation procedures

1. Check whether the oil pressure system leaks oil and the air pressure is normal.

2. Check the transmission belt, cold bed and storage table to check the damage and abrasions of the profile.

3. Before the depth, determine the length of the aluminum profile, and determine the length of the depth, that is, the movement of the main card. The stretch ratio of 6063T5 is 0.5%1%, and the stretch ratio of 6061T6 is 0.8%1.5%.

4. According to the shape of the aluminum profile, the method of clamping is determined, and the large -section hollow and different profiles can be inserted into the deep pad, but try to ensure that there is sufficient clamping area.

5. When the aluminum profile is cooled to below 50 C, open the stretch surface.

6. When the profile is bent and twisted at the same time, it should be corrected first, and then pulls and bend.

7. Test the first and second roots to determine whether the predetermined stretch rate and clamping method are appropriate. Vextis, twist, and check the plane gaps, expand, and mouth. If it is not appropriate, it is necessary to adjust the stretch rate appropriately.

8. When the normal pull depth rate still cannot eliminate bending, twisting, or qualified geometric size, the operator should be notified to stop squeezing.

9. The contour on the cooling table cannot be rubbed to each other, cannot collide, cannot overlap and accumulate, and cannot wipe the flowers.

The work efficiency and service life of the industrial aluminum extrusion machine are closely related to the installation order of the industrial aluminum extrusion machine. The dynamic load when working at the machine, so the installation of the equipment must be performed in accordance with the corresponding installation program.
