Rivet welding platform

The characteristics of gray cast iron parts: wear resistance and good shock resistance, because of graphite in the cast ironis conducive to lubrication and oil storage, so good wear resistance. Similarly, due to the existence of graphite, the shockresistance of gray cast iron is better than that of steel. Process performance is good, because of the high carbon content ofthe gray cast iron, close to the eutectic composition, so relatively low melting point, good fluidity, shrinkage of small, so it issuitable for casting of complicated structure or thin-walled castings, the graphite machining easy formation of chip breaking,so grey cast iron can machinability is superior to that of steel.

Product description

The rivet welding platform is suitable for all kinds of inspection work, the reference plane for precision measurement, the machine tool inspection and measurement standard, the dimensional accuracy or behavior deviation of the parts, and the precision scribe line. The rivet welding plate/rivet welding platform is made in machinery. It is also an indispensable basic tool in testing.

Rivet welding platform material: high-strength cast iron HT200-300 working surface hardness is HB170-240, after two manual treatments (artificial annealing 600 degrees -700 degrees and natural aging 2-3 years) using rivet welding plate / rivet welding platform accuracy and stability Good wear resistance.

The accuracy of the welding platform: according to the standard metrological verification procedures, respectively, 0, 1, 2, 3 four levels.

The welding plate is mainly divided into three types: assembly platform, welding platform and welder platform.

Riveting plate: The T-shaped groove is processed on the top, which is mainly used to fix the workpiece. It is the basic platform used by the fitter to debug equipment, assembly equipment and maintenance equipment.

The technical requirements for the design of the rivet welding plate are generally designed according to the "Technical Industry Standard of the People's Republic of China" JB/T 7974-2000. It is manufactured according to the GB4986-85 standard. The precision level of the rivet welding plate is 00, 0, 1, 2, 3, grade and fine. Planing, flat plate made of ribbed plate and box type, the working surface has a rectangular, square or round shape. The working surface of the rivet welding plate adopts a scraping process, and the working surface can process V-shaped, T-shaped, U-shaped grooves and round holes, long holes and the like.

The basic flat plate (platform) specially used for large-scale equipment has the characteristics of reasonable design, stable structure, high precision and wear resistance. It can realize flat stitching of 3000mm-6000mm, and the product is made by scraping or grinding.

Widely used in machining, tool shop, machine (inspection) repair workshop, large equipment base, measuring room and precision processing inspection, measurement and grinding, and energy measurement, inspection of workpiece flatness, flatness and angle Tolerance value.

The basic plate used in the riveting process, the T-slot is mainly used to fix the welded parts.
