Description
Technical Field
The utility model belongs to the technical field of the forming die technique and specifically relates to a copper bar is accurate to be drawn and is used forming die.
Background
The copper bar extruded continuously has partial distortion and deformation, the size and the appearance need to be finished through stretching, and a copper bar blank passes through a die hole under the action of external pulling force, so that a finished copper bar with the shape, the size and the mechanical property meeting the requirements is obtained, and the copper bar drawing is called. Because the cold drawing production efficiency is high, the cold drawing copper bar is widely applied. At present, the cold drawing method of the copper bar adopts a single mould. For the copper bar with smaller drawing amount, a single die can be adopted for drawing once. However, for the copper bar with a large drawing amount, two times of drawing is often adopted. But the production efficiency is reduced due to larger time interval between two times of drawing, more steps and more complex process; in addition, the existing drawing die is generally integrally formed, and when part of the drawing die is damaged, the whole drawing die needs to be replaced, so that the cost of the drawing die is increased. Therefore, the forming die for the precise drawing of the copper bar is provided.
