[0027] Example:

[0028] Reference Figure 1-Figure 4A ceramic bearing ball blank pressing machine includes a workbench 1, and a support column is fixedly arranged at the bottom of the workbench 1. The support columns are arranged in two to eight groups, preferably four groups, and the four groups are evenly distributed. It also includes: a rotating seat 202 is slidably arranged on the workbench 1, wherein a mold base 2 is rotatably arranged on the rotating seat 202, a lower mold 3 is arranged in the mold base 2, and a plurality of groups of molding holes 301 are evenly opened on the lower mold 3, and a fillet is fixedly arranged at the mouth of the molding hole 301 to facilitate the insertion of the molding column 401. The molding holes 301 are arranged in two to thirty groups, and here, we prefer twenty-five groups, and an upper mold 4 is lifted and lowered on the workbench 1, and molding columns 401 corresponding to the molding holes 301 are fixedly arranged on the upper mold 4, and the molding columns 401 are also arranged in twenty-five groups, The hole 301 is composed of a cylindrical hole and a hemispherical hole, the diameter of the cylindrical hole is larger than the diameter of the hemispherical hole, and the forming column 401 is composed of a cylinder and a hemispherical hole opened at the bottom of the cylinder. Similarly, the diameter of the cylinder is larger than the hemispherical hole, which is convenient for pressing the raw material. A loading plate 5 is fixedly arranged on the workbench 1, and a plurality of groups of quantitative feeding pipes 501 are fixedly arranged on the loading plate 5, and the quantitative feeding pipes 501 correspond to the forming holes 301, that is, the number of quantitative feeding pipes 501 is the same as the forming holes 301, and they correspond one to one. A storage tank for conveying raw materials to the quantitative feeding pipes 501 is arranged next to the workbench 1. When in use, the mold base 2 and the lower mold 3 are moved to the lower part of the loading plate 5 by the rotating seat 202, and then the quantitative feeding pipe 501 is opened to quantitatively add raw materials into the forming hole 301. After the raw materials are added, the rotating seat 202 moves the mold base 2 and the lower mold 3 to the right below the upper mold 4, and then the hydraulic cylinder drives the upper mold 4 to approach the lower mold 3 and press down. Under the action of the forming hole 301 and the forming column 401, the raw materials can be made into ball blanks. After compression molding, the rotating seat 202 moves the mold base 2 and the lower mold 3 to the unloading area. At this time, the second motor drives the mold base 2 and the lower mold 3 to flip, and the ball blank in the lower mold 3 will fall on the unloading rack 6 to complete the compression. Automatic compression can be achieved, and multiple ball blanks can be produced by one compression, which meets mass production and helps to improve production efficiency.

[0029] When in use, by opening multiple groups of molding holes 301 on the lower mold 3 and correspondingly arranging multiple groups of molding columns 401 on the upper mold 4, multiple ball blanks can be pressed at one time. With the cooperation of the quantitative feeding pipe 501 and the rotating seat 202, automatic loading, pressing and unloading are realized to meet mass production and help improve production efficiency. By fixing a discharge rack 6 on the workbench 1, it is convenient to collect the ball blanks and improve the use effect.

A detection seat is fixedly arranged on one end of the workbench 1, and a distance measuring sensor is fixedly arranged on the detection seat. The device is used to detect the distance moved by the mold base 2, and a buffer rod is fixedly arranged on the detection seat. One end of the buffer rod is abutted against the mold base 2 to avoid the mold base 2 from hitting the detection seat, thereby improving the service life. When in use, the screw 204 is driven to rotate by the first motor, and the rotating seat 202 can be driven to slide along the axis of the screw 204. During this process, the mold base 2 and the lower mold 3 can be moved, which is convenient for changing the work station and improving the use effect. In addition, the distance measuring sensor can monitor the movement of the mold base 2 in real time to improve the movement accuracy.
