Carbon steel pipe forging and stamping process

Abstract

The invention relates to a carbon steel pipeline forging process. The carbon steel pipeline forging process comprises the following steps: 1) theoretical analysis, drawing a carbon steel pipeline heating curve, the abscissa is the heating time, and the ordinate is the heating temperature; 2) according to the steps 1) The obtained heating curve of the carbon steel pipeline. The carbon steel pipeline is subjected to heat treatment; 3) The heated carbon steel pipeline is subjected to pier thickening and elongation treatment. The invention provides a carbon steel pipeline forging process with high process precision, good surface quality and simple and reliable casting process.

Description

technical field [0001] The invention belongs to the field of metal forging, and relates to a carbon steel pipeline forging process. Background technique [0002] During the forging process, forging can compact or weld defects such as shrinkage cavities, shrinkage porosity, voids, bubbles and cracks in the as-cast metal structure, and can also refine grains and break inclusions, so as to obtain a certain forging flow. line tissue. In actual production, various forgings are often used to produce various important and heavy-duty machine parts or blanks, such as main shafts and gears of machine tools, connecting rods of internal combustion engines, hooks of cranes, etc., according to production needs. During the processing process, it is necessary to deform it such as upsetting, drawing, reaming, bending, and deep drawing. Not good, coupled with the constraints of forging structure technology, forgings are usually only used as blanks for machine parts. Hot forging is a forgin...

Problems solved by technology

However, there are many hot forging processes, the precision of the workpiece is poor, the surface is not smooth, and the forging is prone to oxidation, decarburization and burning.
