A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials will deform under the action of external force, and then return to the original state after removing the external force. Also called “spring”. It is generally made of spring steel. The types of springs are complex and diverse. According…
DetailsStamping parts In the world, 60~70% of steel products are plates, most of which are finished products after stamping. The car body, chassis, fuel tank, radiator sheet, boiler drum, container shell, motor, electrical iron core silicon steel sheet, etc. are all processed by stamping. Instruments, household appliances, bicycles, office machinery, household utensils and other products…
DetailsA kind of material made by punching the plates, strips or pipes and other profiles is called profiled parts, while castings are metal pieces with certain shape, size and performance obtained by pouring molten metal into the casting mold and solidification. What are the differences between the two? 1. There is a difference between hot…
DetailsMain causes of scratches and solutions: 1. The material is poor and scratched. The raw materials with scratches should be carefully used. If paint or other surface treatment is required, the position of paint or surface treatment must be known. If the scratch is serious, consider whether to use it. 2. The material loading and…
DetailsStamping parts are mainly formed by stamping metal or non-metallic sheets with the help of the pressure of the press and through the stamping die. They mainly have the following characteristics: ⑴ Stamping parts are manufactured by stamping under the premise of small material consumption. The parts are light in weight and have good stiffness.…
DetailsThe cast flange has accurate blank shape and size, small processing amount and low cost, but it has casting defects (air hole, crack and inclusion); The streamline of the internal structure of the casting is poor (even worse if it is a cutting part); A few low-quality flange castings are cast. For small castings with…
DetailsFlange blank is defined as a production object made according to the required shape and process size of the finished flange for further processing. It is mainly divided into three categories: casting flange blank, forging flange blank and hot coil flange blank. Next, we will introduce the application of flange blanks in steel gate valves.…
DetailsAs the name suggests, stamping iron discs are made by pressing the upper tool and lower die on iron plates of different thicknesses with a stamping press machine (stamping machine for short). The specifications of stamping iron discs are not fixed because the cutter and stamping die can be arbitrarily changed to produce stamping iron…
DetailsStamping parts are the forming and processing methods of workpieces (stamping parts) with required shape and size by applying external forces on plates, strips, pipes and profiles by presses and dies to cause plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure processing), which is called forging. Stamped blanks are mainly…
DetailsAbstract The utility model discloses a vehicle armrest hinge structure, Includes hinge upper brackets and hinge lower brackets, A hinged assembly between the upper support and lower support, The chain rotation shaft successively passes through the upper hinge bracket, the first polyoxymethylene friction plate, the first metal friction plate, the lower hinge support, the nut…
