Description

Technical Field

[0001] The present invention relates to the technical field of forging positioning, and particularly relates to a real-time horizontal positioning device for steel ball forging wire-contact type workpieces. Background Art

[0002] In the production of steel ball forging, the cooperation of the die cavity during the forging process is utilized to apply pressure to the blank, causing plastic deformation of the bar stock, so as to obtain a spherical shape and fixed dimensions. The key point of its production lies in ensuring the control of the steel ball forming process, so as to control the internal structure of the steel ball and improve the qualified rate and service life of the steel ball. However, when the existing upper die and lower die are closed, they move in the vertical direction, and the contact between the bar stock and the lower die is a line contact, making it difficult to position accurately in one step. Since the bar stock needs to be placed manually, it is impossible to ensure the absolute verticality of the bar stock. In three-dimensional space, the common view of the operator is that the bar stock is placed vertically, but the side view is still inclined, increasing the non-uniformity of deformation during the steel ball forming process. There is an angle between the force on the bar stock and the axis. After forging and forming, the metal streamline appears on the side of the steel ball, affecting the service life of the steel ball. In addition, since the bar stock deforms at a relatively high temperature, the positioning object applying external contact will accelerate the temperature diffusion of the bar stock and reduce the local temperature, resulting in non-uniform structure of the steel ball after forging and affecting the quality of the forged steel ball.

[0003] To sum up, the existing positioning technology uses manual methods and cannot ensure the absolute verticality of the bar stock in three-dimensional space, resulting in non-uniform deformation of the bar stock during forging and further affecting the quality of the forged steel ball. Summary of the Invention

[0011] Furthermore, the end surface of the Z-axis positioning bolt 8 contacts the outer surface of the vertical support rod 2;

[0012] Furthermore, the end surface of the X-axis positioning bolt 4 contacts the outer surface of the transverse support rod 3;

[0013] Furthermore, the positioning base 12 is made of magnetic material;

[0014] Furthermore, when in use, two positioning laser beam adjustment units are placed at two corners of the positioning base 12, so that the two positioning laser beam adjustment units are placed at a certain angle, and the blank is placed inside the mold 11. The second steering slider 9 on each positioning laser beam adjustment unit slides along the vertical support rod 2, so as to adjust the height of the laser emitter 7 on the first steering slider 5 from the upper surface of the positioning base 12. A first steering slider 5 is provided on the transverse support rod 3, so as to adjust the pitch angle of the emitting end of the laser emitter 7 on the first steering slider 5, so as to make the rays emitted by the laser emitters 7 on the two positioning laser beam adjustment units be set at an angle.

[0033] How it works

[0034] When in use, two positioning laser beam adjustment units are placed at two corners of the positioning base 12, so that the two positioning laser beam adjustment units are placed at a certain angle, and the blank 10 is placed inside the mold 11. The second steering slider 9 on each positioning laser beam adjustment unit slides along the vertical support rod 2, so as to adjust the height of the laser emitter 7 on the first steering slider 5 from the upper surface of the positioning base 12.

The operator can adjust the bar stock according to different situations to complete the positioning of the blank 10.
