Problems solved by technology

[0002] Spherical molds are used for the cold pier process, because large impact force and deformation are required when punching spherical blanks, resulting in frequent mold fatigue, damage, and high failure rate of machine tools
In this process, due to the ordinary light drawing process, the density of the material is not compact enough, and the product quality is difficult to meet the high-quality requirements; and the ring in the middle of the ball embryo produced by the circular mold forms a certain waste of material

Embodiment Construction

[0014] Select a steel wire with a material diameter of 9.0, pass the steel wire through the entrance of the light drawing machine, and perform horizontal light drawing to make the material transversely deformed and increase the tissue density of the material before the cutting pier is pressed; the steel wire that has been lightly drawn will enter the feeding mechanism , the cutting length is determined and cut during the feeding process; the cut steel wire section is sent to the center of the tapered cavity of the mold through the clamp, and the mold is closed, and the steel is pressed by the mold through the punching force of the machine tool itself. Compressed into a ball shape to complete the whole process of punching the ball.

[0015] As shown in the figure, in this process, in order to make a sphere without annulus tapered, the present invention has used a kind of 90~120 ° conical mold, and this mold is made of two semi-bearing steel mold bases 1, 2 Composition, the cavi...

Abstract

The invention discloses a process and a die for stamping girdle-free conical spheres. The process comprises the following steps that: a light process with one-off transverse extrusion is adopted to enable a material to have transverse deformation in the transverse direction so as to increase the tissue density of the material before being cut and forged; the cut-off length of the lightly pulled material is determined in a feeding structure; the lightly pulled material is cut off; and the cut material is sent into a tapering die cavity at an angle between 90 and 120 degrees and stamped so as to form sphere billets and manufacture the girdle-free conical spheres. The research and development of a novel girdle-free conical sphere die and a forging process increase the life span of the die and the utilization rate of the material, reduce the impact force of stamping, and ensure that the sphere billets can be knocked out more smoothly.

Description

technical field [0001] The invention relates to a steel ball stamping process and a mold used in the stamping process; in particular, a stamping process and a mold for a ringless tapered sphere. Background technique [0002] The use of spherical dies for the cold pier process requires a large impact force and deformation when punching spherical blanks, resulting in frequent fatigue and damage of the dies, and a high failure rate of the machine tool. In this process, due to the ordinary light drawing process, the density of the material is not compact enough, and the product quality is difficult to meet the high-quality requirements; and the ring in the middle of the ball blank produced by the circular mold forms a certain waste of material. Contents of the invention [0003] The invention provides a stamping process of a ringless tapered sphere and a die with a certain angle in the cavity. [0004] In order to solve the above technical problems, a stamping process of a ri...
