Description

Technical Field

[0001] The invention relates to the technical field of wear-resistant steel ball production equipment, in particular to a shear-type linear feeding mechanism of a grinding ball forging machine. Background Art

[0002] The ball mill can be used to grind materials such as ores, pigments, and coal. Its working principle is to put the material into the cylinder of the ball mill with wear-resistant steel balls (referred to as grinding balls), and use friction, collision, and impact to crush and grind the material. The grinding ball forging machine is a device used to manufacture grinding balls. Its main principle is to cut the heated alloy round steel into alloy steel billets through a forging process, and to punch the alloy steel billets into a spherical shape. The main function of the feeding mechanism is to convey the alloy steel rods to the feeding port of the grinding ball forging machine. Although the existing feeding mechanism of the grinding ball forging machine can realize the feeding of the heated alloy round steel, it is not easy to maintain the coaxiality of the round steel conveying axis and the feeding port of the grinding ball forging machine after long-term work, which easily causes the round steel conveying axis to deviate from the feeding port, causing wear of the heated round steel and increasing the energy consumption of the equipment. On the other hand, the alloy steel rod conveying wheel of the existing feeding mechanism cannot effectively press the bent alloy steel rods, affecting the linear conveying of the alloy steel rods.

[0003] For example, a steel ball fast forging machine disclosed in the authorization announcement number CN 218873625 U discloses a feeding mechanism, which includes a feeding rack, which is fixed to the front side of the rack, and an upper roller feeding assembly and a lower roller assembly are arranged on the feeding rack, the upper roller feeding assembly and the lower roller assembly are opposite to each other up and down, the upper roller feeding assembly includes two left and right upper bearing seats, the upper bearing seats are penetrated by an upper roller shaft, and the upper roller shaft is provided with an upper roller, and the lower roller assembly includes two left and right lower bearing seats, the lower bearing seats are penetrated by a lower roller shaft, and the lower roller shaft is provided with a lower roller; the feeding rack is provided with two bearing seat slide grooves, and the left and right upper bearing seats slide up and down in the two bearing seat slide grooves respectively; a crossbeam is connected between the left and right upper bearing seats, and the crossbeam has a cylinder, and the cylinder pushes the crossbeam to make the upper roller assembly press the bar. The cylinder pushes the crossbeam to make the upper roller assembly press the bar on the lower roller assembly to realize the conveying of heated bar. However, the upper conveying wheel assembly and the lower roller assembly work in a high temperature environment for a long time and are prone to wear. When the conveying wheel assembly is worn, the upper roller conveying assembly continues to press the bar, and the conveying axis of the bar will shift downward, thereby affecting the coaxiality between the round steel conveying axis and the feed port, causing the round steel to wear and increase the energy consumption of the equipment. On the other hand, when the bent bar passes between the two upper rollers (front upper roller and rear upper roller) and the two lower rollers (front lower roller and rear lower roller), the protruding part of the bar will make the front roller or the rear roller away from the bar conveying axis, causing the roller on the other side to detach from the bar, affecting the linear conveying of the bar. Summary of the invention

[0004] The object of the present invention is to provide a shear-type linear feeding mechanism for a ball forging machine, which can not only realize the linear feeding of round steel, but also maintain the coaxiality between the round steel conveying axis and the feed port of the ball forging machine, thereby preventing the round steel from deviating from the feed port.

[0005] In order to achieve the above technical purpose, the technical solution of the present invention is:

When the cylinder drives the upper clamping arm to rotate on the frame with the upper clamping arm shaft as the axis, the cylinder and the upper clamping arm can rotate with the first cylinder shaft as the axis, and the cylinder can rotate on the cylinder seat with the second cylinder shaft as the axis, so that the cylinder can drive the upper clamping arm to rotate on the frame with the upper clamping arm shaft as the axis.

[0009] In order to facilitate the adjustment of the round steel conveying axis height of the scissor-type linear feeding mechanism, the lower clamp arm gear is meshed with the upper clamp arm gear through the frame gear. By adjusting the meshing angle between the lower clamp arm gear or the upper clamp arm gear and the frame gear, the round steel conveying axis height of the scissor-type linear feeding mechanism can be adjusted.

[0014] The cylinder drives the upper clamping arm to rotate on the frame with the upper clamping arm shaft as the axis center, so that when the upper clamping wheel group approaches the round steel, the upper rotating plate can rotate on the upper clamping arm with the upper shaft sleeve as the axis center, so that the first upper wheel and the second upper wheel always press the round steel. When the bent round steel passes through the first upper wheel and the second upper wheel, the upper rotating plate can also rotate on the upper clamping arm with the upper shaft sleeve as the axis center, so that the first upper wheel and the second upper wheel always press the round steel.

[0015] In order to limit the rotation angle of the upper clamping wheel set, the upper clamping arm is provided with an upper limit plate, and the upper rotating plate is located between the upper limit plate and the lower clamping wheel set.

When the bent round steel passes through the first lower wheel and the second lower wheel, the lower rotating plate can also rotate under the lower clamp arm with the lower shaft sleeve as the axis, so that the first lower wheel and the second lower wheel always press the round steel.

[0019] In order to limit the rotation angle of the lower clamping wheel set, the lower clamping arm is provided with a lower limit plate, and the lower rotating plate is located between the lower limit plate and the upper clamping wheel set.
