[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4A forging die for bearing forging includes a base 1 and a connecting block 2. A connecting block 2 is provided on one side of the top of the base 1, a die base 3 is installed on the top of the connecting block 2, an ejector plate 4 is installed on the other side of the top of the connecting block 2, and a ejector rod 5 is provided on the top of the ejector plate 4. Connecting blocks 2 are vertically provided on both sides of the top of the base 1. The ejector plate 4 is located between the two connecting blocks 2. A mold cavity is provided on the top of the lower die base 3, and an ejector hole is provided at the bottom of the mold cavity. The ejector rod 5 is inserted through the ejector hole. After forging is completed, the ejector plate 4 moves upward, driving the ejector rod 5 to eject the formed bearing from the mold cavity, which facilitates the removal of the product and improves production efficiency.

[0023] The guide positioning assembly 6 is also included. The guide positioning assembly 6 is installed on one side of the outer wall of the mold base 3. The guide positioning assembly 6 includes a positioning seat 601, one end of the positioning block 606 is connected to the compression spring 605, and one end of the compression spring 605 is provided with a clamping block 604. The bottom of the positioning seat 601 is threadedly connected to the adjusting bolt 607. The bottom of the positioning seat 601 is provided with a row of threaded holes. The bottom of the positioning block 606 is provided with a threaded hole of matching size. The adjusting bolt 607 passes through the threaded hole on the positioning seat 601 and is threadedly connected to the positioning block 606. The sliding groove allows the positioning block 606 to slide to a specified position on the positioning seat 601, and then it is fixed by adjusting the bolt 607 to achieve position adjustment within a certain range. The compression spring 605 achieves the functions of buffering and resetting. When the positioning block 606 slides in the dovetail groove 602, the compression spring 605 will be compressed or stretched accordingly according to the movement of the positioning block 606. The elastic force of the compression spring 605 can play a buffering role. After the adjustment is completed, the elastic force of the compression spring 605 can also help the positioning block 606 to quickly reset.

[0024] The cross section of the card block 603 is semicircular, and the size of the card block 603 matches the opening size of the clamping block 604. An adjustment gap is provided between the card block 603 and the clamping block 604 to ensure that the card block 603 can be accurately embedded in the clamping block 604.

[0025] When using this device, first place the device at the designated working position. By providing the guide positioning component 6, when performing bearing forging work, the positioning spacing and length can be flexibly adjusted according to the size and shape of different forgings, so that the mold can adapt to a variety of different forging process requirements, thereby improving the versatility and flexibility of the mold, ensuring the movement accuracy of the mold during operation, reducing the size deviation and shape error of the forging caused by inaccurate guidance, improving the quality of the forging, reducing the vibration and offset of the mold during the forging process, reducing the wear and damage risk of the mold, and extending the service life of the mold.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
