In the following description, a large number of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] Referring to Figure 1 and Figure 2 , a structure schematic diagram of a bearing ring flatness shaping die in an embodiment of the utility model is shown, which comprises an upper die 100, a lower die 200 and a connecting assembly 300, the upper die 100 comprises a circular upper die body, the upper die body has a first end face 110 and a second end face 120 which are away from each other, a plurality of upper sliding grooves 130 are arranged along the diameter direction and pass through the first end face 110 and the second end face 120; the lower die 200 comprises a circular lower die body, the lower die body has a third end face 210 and a fourth end face 220 which are away from each other, a plurality of lower sliding grooves 210 are arranged along the diameter direction and are arranged on the third end face 210; when the upper die 100 and the lower die 200 are coaxially arranged, the upper sliding grooves 130 and the lower sliding grooves 210 are one-to-one corresponding in position; the connecting assembly 300 comprises a bolt 310 and a nut 320, one end of the bolt 310 is slidably embedded in the lower sliding groove 210, the other end is connected with the nut 320 through the upper sliding groove 130, so as to clamp the bearing ring 10 between the second end face 120 and the third end face 210, and the second end face 120 and the third end face 210 are both grooved planes.

[0027] Referring to Figure 3 and Figure 4 , when in use, the bearing ring 10 with flatness out of tolerance is placed between the upper die 100 and the lower die 200, the connecting assembly 300 is used to uniformly fix the upper sliding groove 130 and the lower sliding groove 210 of the die to connect the upper and lower parts of the die, and then the flatness of the end face of the bearing ring 10 is shaped.

[0028] The bearing ring flatness shaping die can make the intermediate bearing ring uniformly bear force as a whole, improve the flatness of the end face of the bearing ring, the end of the bolt is slidably embedded in the lower sliding groove, the position can be adjusted inside the lower sliding groove, and the die is suitable for shaping bearing rings of different diameter specifications.

[0029] Referring to Figure 1 and Figure 2As shown in the drawings, in an embodiment, the lower chute 210 is a trapezoidal chute. The lower chute 210 is arranged as a T-shaped groove, which can embed the end of the bolt 310 into the lower chute 210 and enable the end of the bolt 310 to slide along the diameter direction inside the lower chute 210, thereby matching bearing rings 10 of different diameter sizes. Such an arrangement not only can expand the application range of the mold, but also can ensure that the end of the bolt 310 does not protrude from the lower mold 200, and ensure that the fourth end surface 220 of the lower mold 200 is a complete plane, which can be placed on any flat workbench, such as the workbench of a press machine.

[0030] As shown in the drawings, Figure 1 In an embodiment, the first end surface 110 is provided with a surface-protruding reinforcing framework 140. The reinforcing framework 140 includes a connecting portion 141 located at the center of the upper mold body and a plurality of strip-shaped rib plates 142 arranged radially from the connecting portion 141 to the edge of the upper mold body. A groove 143 is arranged around the outer profile surface of the reinforcing framework 140. In this embodiment, the first end surface 110 is provided with the reinforcing framework 140, which can strengthen the upper mold 100. The groove 143 arranged on the reinforcing framework 140 can not only reduce the weight, but also provide a plane higher than the first end surface 110, so that the connected nut is lower than the reinforcing framework 140, facilitating the application of downward pressure.

[0031] In an embodiment, the connecting portion 141 and the strip-shaped rib plate 142 are integrally formed. Such an arrangement can make the entire reinforcing framework 140 more solid compared to assembly forming, thereby improving the reliability of the entire mold.

[0032] In an embodiment, the longitudinal section of the strip-shaped rib plate 142 is an I-shaped section, as shown in the drawings. Figure 1 As shown in the drawings, the I-shaped strip-shaped rib plate 142 provides a recessed area 1431 for an operator to hold on both sides. When the operator places or removes the upper mold 100, the operator can use the recessed area 1431 for the operator to hold to provide a force point, making the operation more reliable and convenient.

[0033] In an embodiment, the plurality of strip-shaped rib plates 142 are uniformly distributed on the circumferential edge of the connecting portion 141. When the pressure equipment transmits pressure to the connecting portion 141 and the plurality of strip-shaped rib plates 142, it can ensure that the pressure is uniformly transmitted to the end surface of the bearing ring 10, and the planarity shaping effect is good.

[0034] As a preferred technical solution, the strip-shaped rib plate 142 is provided with six strip-shaped rib plates 142, and an upper chute 130 is arranged between two adjacent strip-shaped rib plates 142. It should be noted that the number of strip-shaped rib plates 142 is not limited, and six strip-shaped rib plates 142 are preferred. This can not only ensure reliable reinforcement, but also avoid too much weight and difficulty in moving.

[0035] In an embodiment, two adjacent strip webs 142 are connected to the end of the connecting part 141 in a circular arc transition.

[0036] Further, in an embodiment, the end of the reinforcing framework 140 away from the end surface of the lower mold 200 is a flat surface. In actual operation, the bearing ring 10 can be shaped flat using a press, and the reinforcing framework 140 provides a flat surface for the head of the press to contact, avoiding contact between the connecting points such as the nut 320 and the press, so that the shaping effect is better.
