Waste removal "Wang" Dongfeng Duolika compressed garbage truck evaluation

In modern life, there are many types of garbage trucks. Different garbage trucks have their own advantages. In many models, garbage trucks are among the more technologically advanced ones. The general compressed garbage truck consists of a sealed trash can, a hydraulic system, and an operating system. Rubbish can be compressed and the produced sewage can be treated in time. Compacting garbage trucks not only increases the amount of garbage transported, increases the efficiency of garbage disposal, but also effectively avoids secondary pollution of garbage.

The Dongfeng Dolika compressed garbage truck adopts Dongfeng Dolika's second-class chassis and is modified by Cheng Liwei. The rated load of the vehicle is up to 2010kg, and it can transport more rubbish than ordinary rubbish models.
The length of the vehicle can be selected according to the requirements. There are two specifications of 6470 and 6320mm, width and height of 2050 * 2570 (mm), the maximum speed limit of 90km / h.

From the side of the car, you can have a general understanding of the structure of the entire vehicle. White spray paint is used on the front and the body parts, and the exterior of the car body is wrapped with blue paint.
The wheelbase of the vehicle is 3300mm and it has strong mobility. Steel ladders are welded to the left front of the car body, and guard rails are also installed on both sides of the car to prevent mud splashing and enhance the beauty. At the same time, it helps the operators to climb up and down the ladder.

The rear of the ladder is designed with a steel hydraulic tank with an oil level indicator. Since most of the functions of the vehicle require hydraulic functions, the hydraulic tank is used to store the oil needed to ensure the operation of the hydraulic system. The operator can check the capacity of the oil in the tank at any time.

The tail of the car is no different from the general garbage truck. We can clearly see the tipping bucket, scraper and skateboard. The entire part constitutes the vehicle's compression system. After a series of treatments, the garbage is loaded into the box.

Hydraulic cylinders can be seen on both sides of this model, enabling dumping of the trash can in the dump bin.
In the middle part of the compression pack, a solenoid valve is installed. Through the solenoid valve, we can achieve the functions of scraper, slide plate, tipping bucket, filler and push plate of the garbage truck. The operation of the electromagnetic valve of this model is relatively troublesome and needs to be always correct. Push the button until it finishes processing.

In addition to being controlled by a solenoid valve, this model is also equipped with a manual operation lever. The manual operation lever is located at the rear of the cab and is relatively concealed and can perform the same functions as the solenoid valve.
Above the manual operation lever is provided with a graphic instruction operation, and the corresponding operation lever realizes a corresponding function, which is convenient and practical.

At the bottom of the car body, a hydraulic cylinder is hidden to enable the garbage dumping function.

Dongfeng Duolika Compressed Garbage Truck has all the functions of a general compressed garbage truck. Its environmental protection features are also marked on the announcement. Customers with needs can select it on demand.

Processing steps For Sheet Metal Parts - Custom Sheet Metal Fabrication Service Company
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.

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.
