Dongfeng washing car is the most practical craftsmanship


4.jpg

       It has been said that the price of the sweeping car is expensive because of the modification process of the sweeping car, but the customer generally only sees the real car, and there is no time to go to the factory to observe the modification process of the sweeping car. It is also skeptical about the sweeping car process. Relatively speaking, the price of the sweeping car is too expensive, not worthwhile.

Today, Xiaobian brought some modification procedures for the sweeping car from the sweeping car manufacturer, so that everyone has a general understanding of the sweeping car modification:

Dongfeng washing and sweeping car sub-frame welding:

1. The sub-frame length limit deviation is not more than 10mm, and the width limit deviation is ±4 at any point.

2. The plane tolerance of the sub-frame is not more than 8mm, and the flatness of any 2m is not more than 3mm.

3. The dimensional tolerance of the attachment is strictly in accordance with the requirements of the drawings, without any inclination or deformation defects.

4. The surface of the weld is uniform without slag inclusion, pores and virtual welding. And remove the welding slag, splash, and smooth the unevenness.

Dongfeng washing and sweeping car cover assembly welding:

1. The welding parts of the casing assembly shall be constructed in strict accordance with the drawings and tolerances.

2. The gap between the side door and the door frame is even, and the maximum gap is no more than 3mm.

3. After welding, the appearance is required to be smooth and smooth, without obvious deformation and unevenness.

4. The louver gap is even.

5. The welding is firm, the weld is flat, and there must be no defects such as burning, welding, and porosity.

Dongfeng washing and sweeping water tank body welding:

1. The side plates of the water tank are butt jointed, and there are no obvious wrong edges, sharp corners and pits.

2. The surface of the casing is flat and there is no obvious unevenness.

3. The weld seam is continuous and flat, the welding is uniform and firm, and there are no defects such as pores and blisters that affect the seal.

4. The connecting flange ensures the relative position of the mounting holes, the welding is uniform and firm, and there are no defects such as virtual welding and leakage welding.

5. Install clear water for leak test, no leakage.

Dongfeng washing car sub-engine bracket welding:

1. The welding parts of the brackets shall be constructed in strict accordance with the drawings and tolerances.

2. The length deviation is not more than 5mm, and the diagonal deviation is not more than 4mm.

3. The plane tolerance is not more than 3mm, and the exposed weld surface of the working surface shall not be higher than the upper plane.

4. Weld seams must not have defects such as air holes, solder joints, and trachoma. Clean the welding slag and polish the high weld.

Dongfeng washing and sweeping water pump bracket welding:

1. Install the ear plate welding end is positive and firm, to ensure the coaxiality of the mounting hole.

2. The sleeve is positioned accurately and the welding end is positive, ensuring the coaxiality of the two sleeve holes.

3. The surface of the weld is uniform without slag inclusion, pores and virtual welding. And remove the welding slag, splash, and smooth the unevenness.

Dongfeng washing vehicle air filter mounting bracket welding:

1. The welding parts of the brackets shall be constructed in strict accordance with the drawings and tolerances.

2. Each angle steel is welded firmly and flat, without distortions such as distortion and skew.

3. The welding is firm, the weld is flat, and there must be no defects such as burning, welding, and porosity.

Dongfeng washing and sweeping side rail welding:

1. The side rails are welded at the right end, and the parallelism error of the two beams is not more than 5mm.

2. All welds shall be firm, uniform and beautiful, and shall not have defects such as leakage welding, weld penetration, incomplete penetration, and slag inclusion.

One point of sweat is harvested. Imagine that the Dongfeng washing and sweeping car has the staff's efforts and sweat every step of the process, and it can withstand the test of quality, so its price is reasonable. When you buy a sweeper, you can go to the factory to check with the above-mentioned modification standards. At this time, you will know that the process is very strict, complicated and standard.
