Design principle of side beam cold forming equipment:
This design is based on the principles of reliable use, easy maintenance, maximum standardization, generalization of parts, normalization of service life, low investment, high standard of key parts, maintenance of auxiliary parts, easy exchange of rolls, and standardization of reference.
The design basis of the side beam cold bending forming equipment:
According to the requirements of the demand side, the whole machine will flow automatically, and the product samples will meet the requirements of the drawings, and refer to the national standard GB6723-86 of the national standard for cold-formed section steel (GB6723-86). Variable and allowable deviation > GB6724-86 < Cold-formed Steel Plate > GB6726-86 < size, shape, variable and allowable deviation of Cold formed Steel for Freight cars.
Side beam cold forming machine fuselage and archway assembly:
The fuselage part of the side beam cold forming machine is the main part of the rolling mill, and the other parts are all mounted on the machine, which is the welded structure of the steel plate, and the stress is removed after welding. Each connecting surface, installation surface is finely machined and the installation surface is machined with positioning keyway, which is accurate in location, convenient in installation, and ensures the parallelism between the main shaft of each group of rolling mill and the perpendicularity with the center line of the rolling mill.
Archway assembly is the main part of the machine, a total of 20, from the front to the back of the installation on the fuselage. This assembly mainly consists of front and rear archways, upper and lower spindle, upper cross beam, upper shaft lifting adjusting wire rod, front and rear bearing support and main shaft bearing, etc. The rear arch frame is fixed on the fuselage and is the support benchmark for the upper and lower spindle. The front arch can be disassembled to facilitate the replacement of assembly rolls. The upper and lower spindle is mounted on the bearing support through the bearing. The bearing support can adjust the distance between the upper and lower shafts by adjusting the wire rod along the guide surface of the archway window to suit the installation of the roller with different diameters.
