Rivet welding flat plate is a basic cast iron flat plate widely used in riveting and welding processes. It has holes on the working surface for cleaning some iron slag and welding waste during riveting and welding, and T-shaped grooves for fixing the welded parts. The holes are mainly used to clean some iron slag and welding waste during riveting and welding, and the T-shaped grooves are mainly used to fix the welded parts to prevent welding deviation caused by unstable welding parts. The material is generally high-strength cast iron HT200-300, with a working surface hardness of about HB170-240. After two manual treatments including manual annealing at 600-700 degrees and natural aging for 2-3 years, the accuracy of this product tends to be more stable and the wear resistance is better.
Calculation formula for flatness of rivet welded flat plate:
Level 000: 1 × (1+d/1000) Level 1: 8 × (1+d/1000)
Level 0: 2 × (1+d/1000) Level 2: 16 × (1+d/1000)
Level 0: 4 x (1+d/1000) Level 3: 40 x (1+d/1000)
Rivet welding flat plate accuracy: According to the national standard metrological verification regulations, there are four levels: 0, 1, 2, and 3. The working surface is divided into rectangular, square, or circular shapes, and V-shaped, T-shaped, U-shaped grooves, circular holes, long holes, etc. can be machined on the working surface to meet the different working needs of different flat plates in production.
The basic production process of riveting and welding flat plates is:
1. Rivet welding flat blank: make drawings according to technical requirements, make wood shapes according to drawings, mix ingredients, shape, dry, cast, sand, clean, and inspect various parts of the blank;
2. Rivet welding flat plate machining: visual inspection and marking, processing, and inspection;
3. Leveling of riveting and welding flat workpieces, manual scraping and grinding, and inspection by the inspection department;
4. Appearance treatment, painting, packaging, and storage of riveting and welding flat plates.
The cast iron riveting and welding plate should be installed and debugged before use. Then it can be used. Working on riveting and welding plates without proper installation and debugging is meaningless. Installing and debugging riveting and welding plates by non professionals is a violation of regulations, which may damage the structure of the riveting and welding plates and even cause deformation, making them unusable. So before use, we need professional staff to install and debug the cast iron flat plate. Installation and debugging by non professionals are illegal operations and must never be used.
