When buying a car, many people will consider what kind of car is more valuable, otherwise it will be very sad to buy the car immediately after the price drop. And everyone knows that some niche cars are doing poorly in terms of value preservation. Generally, there are not many people buying small cars, and it is more difficult to change parts and repairs. Although more personal, but after buying, when you sell used cars, there will be a very serious price cut. Let me tell you what to do to keep the car worthwhile. What the car can do to keep the car worthwhile . First, paint maintenance The appearance of a good car bought on the back side is very important, just like there are a lot of cars that are refurbished and can be sold. This is mainly because of the effort on the paint surface. Generally, people will do waxing and polishing, like polishing to do less, generally polishing for a long time will hurt the car paint, so that the car paint thin. There are also technologies that last a long time, such as lacquer plating, which lasts for five years, and makes the car look very bright, and it can also prevent acid rain. But the price is also very high, no matter what kind of paint maintenance we have to do one. Second, chassis armor Many people think that chassis armor should only be installed on the road in the countryside, but there is no way to control where you drive after you buy a car. Sometimes, when you borrow a car, what do you do, so install a chassis armor for the car. This will not cause damage to the chassis regardless of the environment. Generally, when it is rainy, it is most afraid of corroding the chassis of the car. It is not afraid of the chassis armor, and it can also play the role of a newspaper, but this is not necessary. Third, glass Many bodywork is good-looking, one-quarter or one-third of the field of vision is glass, so the maintenance on the glass can not be less, many people put the explosion-proof film on the car, and also let the people inside the car look outside. It is not damaged by the sun. In fact, many explosion-proof glass is not as safe as the explosion-proof membrane on the car. After the explosion-proof film is attached to the car, even if there is an accident, it will not be hurt because the car glass is broken, so this is very important in safety. What to do can keep the car worthwhile, and what the car can do to keep the car worthwhile is finished. In fact, if you want to keep the car at least, you can't let the car wading. After the car is in the water, it can be used normally after repairing the car. However, the price is 50% larger, so it is very important to put the car into the water. Pay attention to daily maintenance. Pay attention to the maintenance mentioned in the above small series, so when you sell used cars, it is not bad with the new car. How can you give you a low price?

10. Assembly. The so-called assembly is to group multiple parts or components together in a certain way to make them into a complete 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, it needs to be reworked and reworked, which will waste a lot of processing man-hours and increase The cost of the item. So pay special attention to the protection of the item.

1. Design and draw the part drawing of its sheet metal parts, also known as three views. Its function is to express the structure of its sheet metal parts by means of drawings.
2. Draw an unfolded drawing. That is, unfold a part with a complicated structure into a flat piece.
3. Unloading. There are many ways to unload, mainly the following methods:
a. Shearing machine cuts the material. It uses the shearing machine to cut out the length and width dimensions of the expanded drawing. If there are punching and corner cutting, then the punching machine is combined with the die to punch and corner to form.
b. Punch blanking. It is the use of a punch to punch the structure of the flat part after the parts are unfolded on the plate in one or more steps. Its advantages are short labor hours, high efficiency, and can reduce processing costs. It is often used in mass production.
c. NC CNC blanking. When NC blanking, you must first write a Cnc Machining program. That is, use the programming software to write the drawn expanded diagram into a program that can be recognized by the NC CNC machining machine. Let it follow these programs step by step on a piece of iron plate On the top,punch out the structural shape of its flat parts.
d. Laser cutting is the use of laser cutting to cut the structure and shape of the flat piece on an iron plate.
4. Flanging and 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. This can increase its strength and avoid slippage. Generally used for sheet metal processing with relatively thin plate thickness. When the plate thickness is large, such as the plate thickness of 2.0, 2.5, etc., we can tap directly without flanging.
5. Punch processing. Generally, punch processing includes punching and cutting corners, punching blanking, punching convex hull, punching and tearing, punching and other processing methods to achieve processing purposes. Its 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. 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. Riveted to the sheet metal part.
7. Bending. Bending is to fold 2D flat parts into 3D parts. Its processing requires a folding bed and corresponding bending molds to complete the operation. It also has a certain bending sequence, and the principle is to make the next cut The first fold that does not cause interference will produce the interference back fold.
8. Welding. Welding is the group welding of multiple parts together to achieve the purpose of processing or the edge welding of a single part to increase its strength. The processing parties generally include the following: 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; robot welding is mainly in-material It is used when the parts are large and the welding seam is long. Such as cabinet welding, robot welding can be used, which can save a lot of 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, and its function is mainly to plate on the surface of the material. A protective film is applied to prevent oxidation; the second is to enhance the adhesion of its baking paint. Electroplated multicolored zinc is generally treated with cold-rolled plate surface treatment; chromate and oxidation are generally used for surface treatment of aluminum plates and aluminum profiles; its specific surface The choice of treatment method is based on the customer's requirements.
