Description

Technical Field

[0001] The utility model relates to the technical field of broaching machines, in particular to a broaching machine for cold drawing production of flat steel. Background Art

[0002] Cold drawing refers to the process of stretching steel using tensioning machinery at room temperature. Cold drawing will produce a cold drawing strengthening effect, that is, the tensile stress exceeds the yield strength of the steel and is unloaded, and the yield strength of the steel will increase to the unloading stress level. The yield strength of the steel can be increased by 20% to 30% after cold drawing, and it also has the effect of rust removal and straightening. At present, flat steel needs to be cold drawn using a drawing machine during the production process.

[0003] When cold drawing the existing flat steel, the cold drawn steel needs to pass through the cold drawing hole on the forming die, and then be pulled out of the cold drawing hole by the traction mechanism, and finally the flat steel of the required specifications can be obtained. During factory production, due to the different specifications of the flat steel produced, each specification of flat steel needs to be matched with the corresponding forming die during production. After the production of one specification of flat steel is completed, it is necessary to wait for the mold to be replaced before the next specification of flat steel can be produced. If a small batch of flat steel of other specifications is temporarily processed during production, a complete mold replacement is also required, which takes a long time. Utility Model Content
