Precautions for Squeezing Aluminum Profile Production! -Ruminum Profiles Supplier

1. The aluminum rod furnace must be equipped with the actual situation of the production orders and the mold. The installation length is appropriate, the material is correct, the surface is smooth, the groove has no grooves, and the quality (crystallization, ingredients, density, and non -burning). Pay attention to the identification and spacing of different aluminum rods. Pay attention to the position of the stove and the width of the chain, and pay attention not to loosen each other (use corner iron, do not use aluminum that is easy to soften at high temperatures) to prevent the stove from blocking the stove. Pay attention to the aluminum rod when transporting and installing the stove. Essence Personal damage and equipment accidents. Frequent inspection chain, big head needle, runner, tension column and other equipment. Regularly check the actual temperature of the aluminum rod, the data of the instrument value (not more than 560 degrees), and properly cool (less than 520 degrees) after the machine is stopped for a long time, and always check whether the cutting gun is working, the circulating fan is running, the cooling water (water pump (water pump (water pump (water pump (water pump (water pump (water pump (water pump (water pump (water pump (water pump ) And other equipment is in good condition.

2. Stretching aluminum profile

(1) During the recovery, movement, and stretching process, no rubbing, pulling, overlapping, crowded or entangled aluminum profiles on the cooling bed. There should be a certain interval between each other. The length of the facilities and output of the easily bend should be processed in time, and mutual protection should be performed if necessary.

(2) When stretching the profile, the profile must be cooled to less than 50 degrees before moving it into the stretching rack for stretching.

If the temperature is too high, stretching will burn the human body and burn the top.

In addition, because the internal stress of the profile cannot be completely eliminated, absolute waste will be available before and after aging, such as bending, twisting and poor performance.

(3) Because the top has the effect of preventing heat dissipation, it must be flipped up and down with high decorative surface requirements to facilitate uniform heat dissipation and reduce the horizontal highlights caused by uneven heat dissipation and crystalline. Pay attention to wall thickness.

(4) Pay attention to the small feet with high and wide ratio, long hanging, large arc, large differences in wall thickness, and strange shapes, fine teeth, arc surfaces, tilt tables, and opening, etc. The size of the spots is deformed, twisted, spiral deformation and other contour defects.

(5) The stretchous amount is controlled at about 1 %.

For example, the stretching volume after the 25M profile is straight should be straightened about 25cm, but it must not exceed 2 %. The production should be adjusted according to the actual situation of the material unloading and various specific requirements (opening size, surface quality, external size, inner diameter size, wall thickness size, extension rate, etc.), and seek technical requirements to meet each other. Need a certain amount of stretching. Excessive stretching can cause the size deviation of the head, the middle and the tail, the waters on the surface, the traces of the water -like distortion (fish scales), the low stretch, high hardness and brittleness. Too low stretching can reduce the compressive strength and hardness of the contour, and even the time limit (quenching) cannot increase the hardness, and the contour is easy to bend into arc.

(6) In order to control the amount of stretching deformation and better control the size changes of the entire contour, appropriate special pads and appropriate methods must be used. Especially for open materials, arc materials, cantilever materials, and curved outlines, the stretch clips should be paid more reasonable and effectively. If necessary, the person should control the middle of the stretch outline to concentrate or buffer to ensure that the tensile size of the head, middle and tails meets the contour requirements.

3. Saw and framework for aluminum profiles

(1) The materials on the conveyor frame should be marked with the material head and the joints, and the materials should not be rubbed with each other, and the length of the material should be protected by each other. The contour should be straight front and back, and the cut surface should not be tilted. Check the top of the machine rack and plastic parts. Pay attention to the exposed iron frame and other sharp and hard metals.

(2) Oxidation, spray, sand spray, inverted, punching, material, sawing, packaging, aging, natural materials and other post -processing requirements, and the profiles of different materials must be frame and transport.

(3) When structured, please pay attention to long profiles, thin -walled materials, arc materials, open materials, and solid small cross -section materials, plates, high surface requirements, mutual locks, self -locking or difficult cantilever ratio, separated outlines, separated outlines Framework methods and methods, as well as necessary auxiliary tools, bands, etc. The buffer band (cushion) should be corresponding, arranged correctly, and has a proper distance and quantity. The configuration file that needs to be overhead must be stacked overhead.

(4) Pay attention to the position of stacking the profile in the frame to avoid the weight and weight at both ends, otherwise it may cause accidents, such as stacking and sliding of the profile. Pay attention to the cutting speed of the saw, the burr on the cutting surface, and pay attention to adjust the amount of fuel injection of the sawer. Pay attention to the pressure of the sawing bed. Pay attention to avoid personal injury accidents when cutting operation. When cutting, it is strictly forbidden to force force on the two outside of the profile to avoid clipping the saw when the sawing material, which will cause the hammer to occur, and immediately damage the material and hurt the personnel.

(5) Pay attention to blow away the aluminum dandruff, scrape the branny, the interval should be appropriate, the hanging should be safe, and the stacking frame should be aligned. The stacking frame number cannot exceed the requirements of the 4 -layer quantity specified by the company.

(6) Put it lightly when lifting and frame. Small materials, thin materials, long materials and flat materials. Solid small materials and other flexible materials must be lifted in the middle. Whether the mount will cause difficulties in the processing and production of subsequent processes (sawing, oxidation, packaging, improvement and transportation), affects efficiency, and cannot even be processed and produced normally.
