The weighbridge is also called the weighbridge Truck scale , English is truck scale, which is the main weighing equipment used by factories, mines, businesses and other enterprises for measuring bulk goods. The weighbridge is also called the weighbridge, which is called Electronic scale in English. It is the main weighing equipment used by factories, mines, merchants and other businesses for measuring bulk goods. Before the 1980s, the common electronic weighbridge was a mechanical electronic weighbridge, which was purely mechanically constructed using the lever principle, also known as a mechanical weighbridge. In the mid-1980s, with the maturing of high-precision weighing sensor technology, the mechanical weighbridge was gradually replaced by the weighbridge with high accuracy, good stability and easy operation.
With the continuous development of China's economy, electronic floor scale manufacturers and mines all need large-scale weighing equipment. Floor scale is a good choice, and the price of different floor scales varies greatly. So, does the manufacturing process of the weighbridge have anything to do with the price? This article will give you a detailed introduction.
Production process and flow of main electronic weighbridge:
(1) The grooving machine is used for grooving. The chamfer of the groove type is round, without a 90 degree rigid right angle, and it is connected to a triangular structure.
⑵. U-shaped beam shall be cold-rolled with steel plate not less than 6mm; The panel is Q235 international steel plate.
⑶. The machining workshop has complete processing equipment, self production of accessories, and customized special structures.
⑷. The automatic welding machine will fully weld, and the oxygen inside the U-beam will be exhausted during the welding process, so the partial inert environment will be used to avoid internal corrosion.
(5) The track submerged arc welding is adopted for the middle seam welding of the plate, and the groove welding is formed at one time, without bubbles, solid and beautiful.
(6) The parts of electronic weighbridge shall be welded with CO2 protection welding and full welding. No faulty spot welding. Ensure the strength of the connector, and there is no fatigue deformation after long-term use.
(7) Sand blasting machine is used to remove oxide layer to ensure paint adhesion.
(8) Two coats of finishing paint for weighing platform shall be sprayed and air dried, and spraying is optional. The paint shall not fade and have strong adhesion. All connectors shall be galvanized.
(9) The bottom surface of the scale body shall be consistent with the surface process. Sand blasting, water-based rust prevention, water-based rust prevention primer and finishing coat shall be applied twice. The structure is designed to prevent rats from biting.
Different manufacturing processes of weighbridge affect the price
1. Structural difference of weighbridge:
Good weighbridge adopts a new generation of U-shaped beam structure, with uniform force, more stable and durable. However, some small manufacturers prefer to use the channel steel structure weighbridge, because the channel steel structure weighbridge has lower requirements for production equipment.
2. Difference of production equipment:
Large well-known manufacturers will use large steel plate bending machines, plate shears, metal flaw detectors and other large and valuable equipment. Features of electronic weighbridge On the one hand, the use of these equipment can make the weighbridge more accurate and better quality, on the other hand, it can carry out better quality inspection on the weighbridge, and repair and rework unqualified products. Ensure that the weighbridge under the customer's stress is high-quality and qualified products.
3. Difference of welding process:
Large well-known weighbridge manufacturers all use full welding. Many small manufacturers use spot welding to save costs, which is irresponsible. Although no difference can be seen in the short term, it takes a long time. The weighbridge body that uses spot welding is easily damaged and deformed.
4 Difference in thickness between panel and U-beam:
The scale body panel of the regular weighbridge manufacturer is generally 10MM panel, and the thickened ones are 12MM, 14MM, 16MM and other specifications. The U-shaped beam is made of 6MM steel plate, and the reinforced type can use BMM panel. However, many small manufacturers' weighbridge panels are not up to standard. Many 10MM panels are only 8MM, and low-quality steel plates are used, which seriously affects the quality of the weighbridge body.
5. Paint difference
Good weighbridge is made of zinc rich deer paint, which has strong antirust ability. The panel is painted with polyhydrogen ester resin finish, which is super abrasive and anti rust. The low-quality weighbridge uses ordinary paint, and its rust resistance is relatively poor.
