Processing Process Of Air Conditioning Cabinet Shell



There are differences in the structure of the air conditioning cabinet shell, so many technological processes will be different. Hop technology will introduce the processing process of the lower case cabinet shell in detail.

1. Design and draw the parts diagram of its chassis cabinet shell, also called three views. Its role is to express its structure with drawings.

2. Draw an unfolded drawing, that is, unfold a part with a complex structure into a flat piece.

3. There are many ways to unload materials, mainly as follows:

a. Cutting by the shearing machine is to use the shearing machine to cut out the length and width dimensions of the unfolded drawing. If there are punching and corner cutting, then turn the punching machine and die punching and corner cutting to form.

b. Punch blanking is the use of a punch to punch out the structure of the flat part after the parts are unfolded on the plate in one or more steps. Its advantages are short labor-consuming hours, high efficiency, and can reduce processing costs. It is often used in batch production of chassis cabinet shells.

c. NC blanking, the NC machining program must be written first when NC blanking. It is to use the programming software to write the drawn expanded diagram into a program that can be recognized by the NC numerical control processing machine tool. Let it follow these procedures step by step on an iron plate to punch out the structure and shape of its flat piece.

d. Laser blanking is the use of laser cutting to cut out the structure and shape of the flat piece on an iron plate.

4. Flanging tapping, flanging is also called hole extraction, which is to draw a slightly larger hole on a smaller base hole, and then tap the hole. Doing so can increase its strength and avoid slippage. It is generally used for the processing of chassis and cabinet shells with relatively thin board thickness. When the plate thickness is larger, such as 2.0, 2.5, etc., we can tap directly without flanging.

5. Punch processing. Generally, punching processing methods include punching and cutting corners, punching and blanking, punching convex hull, punching and tearing, and punching to achieve the processing purpose. The processing requires corresponding molds to complete the operation. There are convex molds for punching convex hulls, and tearing forming molds for punching and tearing.

6. Pressure riveting and pressure riveting As far as our factory is concerned, pressure riveting studs, pressure riveting nuts, pressure riveting screws, etc. are often used. The pressure riveting method is generally completed by a punch or hydraulic pressure riveting machine, and riveting them to Chassis cabinet shell.

7. Bending, bending is to fold 2D flat parts into 3D parts. The processing requires a folding bed and corresponding bending molds to complete the operation. It also has a certain bending sequence, and its principle is to fold first that does not interfere with the next cut, and then fold back that interferes.

8. Welding, welding is to weld multiple parts together to achieve the purpose of processing or to weld the edge seam of a single part to increase its strength. Its processing parties generally have the following types: CO2 gas shielded welding, argon arc welding, spot welding, robot welding, etc. The selection of these welding methods is based on actual requirements and materials. Generally speaking, CO2 gas shielded welding is used for iron plate welding, argon arc welding is used for aluminum plate welding, and robot welding is mainly used when the material parts are large and the weld seam is long. Such as cabinet welding, robot welding can be used, which can save many tasks and improve work efficiency and welding quality.

9. Surface treatment, surface treatment generally includes phosphating film, electroplating colorful zinc, chromate, baking varnish, oxidation, etc. Phosphating film is generally used for cold-rolled plates and electrolytic plates. Its function is mainly to coat a protective film on the surface of the material to prevent oxidation, and then it can enhance the adhesion of the paint. Electroplating multicolored zinc is generally used for surface treatment of cold-rolled plates; chromate and oxidation are generally used for surface treatment of aluminum plates and aluminum profiles. The selection of specific surface treatment methods is determined according to customer requirements.

10. Assembling, the so-called assembly is to group multiple parts or components together in a certain way to make it into a complete enclosure material. One thing that needs to be paid attention to is the protection of the materials and no scratches. Assembly is the last step in the completion of a material. If the material cannot be used due to scratches and needs to be reworked, it will waste a lot of processing man-hours and increase the cost of the material. Therefore, special attention must be paid to the protection of materials.
