What problems should be paid attention to in industrial aluminum processing?

Today I want to share with you what problems should be paid attention to in industrial aluminum processing.

The aluminum profiles just produced are generally 6 meters long, and the conventional accurate size is 6020mm, which can be fixed for aluminum profiles in addition to these conventional assembly line profiles. However, just imagine, each aluminum profile frame is made of a combination of aluminum profiles of different lengths, so the aluminum alloy profile must be cut to the required size.

Therefore, often industrial aluminum processing should pay attention to the accuracy of cutting, the general cutting accuracy is within +, but with the progress of science and the innovation of machines, now the general cutting accuracy can be accurate to within +. In addition, in addition to the cutting accuracy, industrial aluminum processing also needs to pay attention to the diameter accuracy of the punching hole and the depth of the threaded hole, otherwise there will be difficulties in the subsequent installation of the aluminum profile shelf.

The first point that needs to be paid attention to when processing aluminum profiles is that its sawing, processing equipment and other tools need to ensure a certain accuracy, and the measuring tools and fixtures used must also meet the accuracy and standards of measurement. And this kind of equipment must be regularly identified, measured and certified. The sawtooth should also be checked regularly to ensure that there are no burrs on the surface of the cut aluminum profile.

Before the processing of the aluminum profile, it is necessary to ensure the correctness of the drawing, and ensure that there is no deformation or scratch on the surface of the aluminum profile, and carefully check it before processing. After processing, the size of the aluminum profile should be sampled and inspected, and the size of the aluminum profile of the same size should be kept uniform. After the aluminum profile is processed, the aluminum chips and dust on the surface of the aluminum profile should be removed to ensure that the surface of the aluminum profile is clean.

Industrial Method. Aluminium is present in a variety of rocks or ores in a chemical form, such as feldspar, mica, kaolinite, bauxite, alum, and so on. It is prepared by eutectic electrolysis of aluminum oxide and cryolite (3naf alf3).

The reaction process of extracting aluminum from bauxite.

Dissolution: Bauxite is dissolved in NaOH (AQ).

Al2O3+2NaOH = 2Naalo2+H2O filtration: remove residue iron oxide (Fe2O3), sodium aluminosilicate, etc.

Acidification: Excessive CO2 is introduced into the filtrate

naalo2+co2+2h2o=

al(oh)3↓+nahco3

Filtering, burning.

al(oh)3

2Al(OH)3=(high temperature)Al2O3+3H2ONote: In order to reduce the melting temperature of alumina during electrolysis, cryolite (3Naf Alf3) is added to Al2O3

Electrolysis: 2Al2O3(L) (energized) =

4al+3o2

Note: AlCl3 is not electrolytically fused

Reason: ALCL3

It is a covalent compound and its molten state does not conduct electricity.

The method of industrial smelting of aluminum: electrolysis of aluminum oxide.

The reaction equation is: 2Al2O3 = energized = 4Al+3O2 (gas mark symbol).

When it comes to industrial aluminum profiles, everyone knows that it is made of aluminum alloy, which is extruded through molds and extrusion production lines. But in fact, industrial aluminum profiles or industrial aluminum products are used in the molding process of many processing technologies. Let's take a look:

1.Ingredients increase the hardness of the product. We know that industrial aluminum profile is a kind of aluminum alloy profile, there are aluminum-magnesium-silicon alloys, aluminum-zinc alloys and so on. This increases the hardness and bearing capacity of the aluminum profile.

2.Smelt out impurities. The higher the purity of aluminum, the better the performance. Therefore, the impurities are removed through the melting furnace to increase the performance of the aluminum profile.

3.Casting molding. Have you ever seen the ancient iron-striking process? The casting and molding of industrial aluminum profiles is similar to this.

4.Extrusion. Each specification of aluminum profile has a corresponding production mold, put the aluminum into the mold, through extrusion to form the aluminum profile you need.

5.Oxidation processing. The surface of the industrial aluminum profile is treated with silver white oxidation, which is elegant and beautiful and corrosion-resistant.

The above is the process technology used in each step of the final forming process of industrial aluminum profiles. Therefore, when choosing aluminum profiles, it is necessary to conduct an investigation of the strength of aluminum profile manufacturers.

2. Process requirements.

1.The aluminum platform machining center adopts semi-enclosed automatic control mode for processing; 2.A clamping needs to process the groove, notch, and side light hole on the platform panel 3The production cycle time needs to meet the requirements;

4.The process, tool and feed can be adjusted according to each different part, so that the processing technology of each part becomes a fixed formula, and the operation and adjustment are fast and convenient;

5.It is necessary to design the upper and lower parts of the tooling and the positioning tooling, so that the workpiece is clamped quickly, the positioning is accurate, and the disassembly is convenient; 6.The workpiece material has the characteristics of easy cutting, and it is necessary to consider the problems of chip breaking and convenient chip removal; 3. Specific requirements.

In addition to the special accident of mold customization, the deep-processed aluminum profile is also very special. There are many aluminum profile factories in China, and most of the aluminum profile specifications are very complete, such as 20, 30, 40 or even 90, 100, 120 and other series are perennial spot **. However, there are only some manufacturers that can do deep processing, and even fewer of them can make deep processing to a certain height.

1: Structural analysis and design according to the site inspection.

2: Dimensional measurement according to the drawing.

3: Carry out precise cutting (cutting can be divided into right-angle cutting and different angle cutting) 4: Connection analysis according to the structure and different accessories.

5: Combine the accessories to start the group assembly.

6: Overall structure inspection.

We need to start from the preparation before production, focusing on production and processing, self-inspection, spot check of each product of the quality inspection department, and comprehensive inspection of complex and difficult products. Here's how:

The preparation work before the production of industrial aluminum profile products, carefully check the drawing requirements from beginning to end, so as to achieve a thorough understanding, mark the parts that are prone to errors and be familiar with them. Pay attention to processing and production, handle the product with care, measure every size, accurate processing, and recheck whether each profile must be correct; For mass production of the same size, the first product must be re-inspected, and the other products must be sampled from time to time and quantitatively, so as to check and check more to ensure a 100% pass rate to the next process.

The task of the industrial aluminum profile assembly department is not only to conduct self-inspection, but also to carefully check the drawings, and fully grasp every assembly detail and processing requirements; When assembling, it should be carried out in strict accordance with the requirements of the drawings, and there should be no sloppiness. The organized industrial aluminum profile products will be comprehensively inspected for omissions and negligent parts. The quality inspection department conducts a comprehensive sampling inspection, and the products with special requirements are carefully inspected comprehensively.

Qualified industrial aluminum profile products are transported to the packaging department for surface cleaning, sorting, and packaging ready to go.

1. Drawing. Drawings are the ideal initial embodiment, so technicians need to draw accurate three-dimensional drawings according to customer needs, and technicians should also be able to judge whether the customer's needs are reasonable or give feasible suggestions for later adjustment and modification.

Second, processing standards. Aluminum profile processing services include cutting, punching, tapping, etc., if you can't process accurately according to the size, it will cause the aluminum profile to be assembled. Therefore, the standards for aluminum profile processing are:

The surface is not smooth and rough, the size cutting error is within the range, and the tapping and so on should be consistent with the size of the drawing.

Third, it is the assembly requirements. Transport the processed aluminum profile to the assembly area, wipe the surface of the aluminum chips, prepare the tools, and assemble according to the drawings. Wrap it in a protective film, put a label on it and wait for it to be shipped.

It is customized according to customer needs
