The processing of bearing ring blanks is the first process in bearing production. The quality of bearing ring blanks and the productivity will directly affect the quality and performance of bearing products, and will also affect the economic benefits of the enterprise. Therefore, the processing of bearing ring blanks has become an important process in the bearing processing process and has always been highly valued by enterprises.

[0003] At present, the commonly used processing technology for forging bearing ring blanks includes a series of processes such as preheating, shearing, heating, upsetting, reverse extrusion molding, bottom cutting, hole expansion, and shaping. The equipment used in this series of processes includes electric heating furnace, first press, second press, third press, rolling expansion machine, shaping punch and other equipment. The specific process operation process is: first, the bar is heated by an electric heating furnace, and then cut into bars of a certain length by the first press, and then heated by a medium frequency induction heating furnace and upsetting by the second press. After upsetting, it is manually transferred to the next process operator to complete the two processes of extrusion molding and punching. Finally, it is manually transferred to the worker operating the rolling expansion machine to expand the blank after punching, and the expanded blank is sent to the shaping punch for shaping. During the entire production process, multiple workers are required to operate online at the same time. At the same time, when the workpiece needs to be manually transferred in the forming area, it is also necessary to manually flip the workpiece. This further increases the workload of workers, increases production costs, reduces the quality of workpieces and makes it difficult to ensure the consistency of workpiece quality, and reduces production efficiency.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-2 As shown, the bearing ring automatic forging production line of the utility model includes a preparation area 01, a forming area 02 and a diameter adjustment area 03 which are sequentially arranged according to the production process. The preparation area 01 is mainly used to cut the bar material into blanks of the same length and heat the blanks to a set temperature. The forming area 02 is mainly used to stamp the blanks. The diameter adjustment area 03 is mainly used to expand the hole and adjust the diameter of the workpiece after stamping.

[0022] Specifically, the operator places the bar material on the material rack 04 and arranges the bar material. A primary heating furnace 05 for heating the bar material for the first time is provided on one side of the material rack 04. A cutting punch 06 for cutting the heated bar material is provided on one side of the primary heating furnace 05. The cutting punch 06 is a 160T open punch. The cutting punch 06 punches a complete bar material into several blanks of the same length. A secondary heating furnace 07 for heating the blank material again is provided on one side of the cutting punch 06. The secondary heating furnace 07 heats the blank material again and monitors the temperature of the heated blank material. The blank material that meets the temperature standard enters the forming area 02, and the blank material that does not meet the temperature standard continues to be heated. In the preparation area 01, the bar material is preliminarily heated and then cut by the cutting punch 06. Then, the blank material is heated twice to ensure that the temperature of the blank material entering the forming area 02 meets the set requirements. Compared with the traditional method of processing blanks, it is faster. At the same time, the blank is heated again by the secondary heating furnace 07 to avoid the phenomenon that the temperature of the blank entering the forming area 02 is too low to be formed. After the blank is heated, the blank is transferred to the No. 1 punch press 09 by the No. 1 robot 08. The No. 1 robot 08 is set between the secondary heating furnace 07 and the No. 1 punch press 09. The No. 1 punch press 09 is a 250T open punch press. The No. 1 punch press 09 is mainly used to upset the blank and perform preliminary punching on the upset blank. The specific process is that the No. 1 robot 08 takes the blank from one side of the secondary heating furnace 07 and places it in the upsetting die of the No. 1 punch press 09 to upset the blank. The No. 1 robot 08 then sends the upset product to the forming die of the No. 1 punch press 09 for preliminary forming. The No. 2 manipulator 10 takes the finished product from the No. 1 punch press 09 and transfers it to the No. 2 punch press 11 after rotating it 180 degrees. The No. 2 punch press 11 is mainly used for trimming and leveling the formed product. The No. 2 punch press 11 is a 200T open punch press, and the No. 2 manipulator 10 is located between the No. 1 punch press 09 and the No. 2 punch press 11. After the No. 2 punch press 11 trims and level the formed product, the No. 3 manipulator 12 located on one side of the No. 2 punch press 11 takes the product out of the No. 2 machine tool and places it in the conveyor line 13. The No. 1 manipulator 08, the No. 2 manipulator 10 and the No. 3 manipulator 12 are in the same plane in the horizontal direction and are of the same model. By setting three manipulators of the same model on both sides of the No. 1 punch press 09 and the No. 2 punch press 11, it is ensured that no manual participation is required during the forming process of the product. The purpose of automatic forming is achieved. The conveyor line 13 transports the finished product to the reamer 14 to reamer the product again. The reamer 14 is a double-axis reamer 14. After the reamer is completed, the product is sent to the sizing machine 15 through the conveyor line 13 for further processing of the holes on the product. The sizing machine 15 is a hydraulic sizing machine 15, and the holes on the product are processed by the reamer 14 and the sizing machine 15 respectively.The outer dimensions of the bearing ring are made closer to the design dimensions, thereby reducing the amount of turning in the subsequent mechanical processing process, thereby improving the overall production efficiency of the bearing ring. The mechanical processing described in this application refers to the process of changing the outer dimensions or performance of the workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing.

[0023] In order to achieve upsetting and stamping on the No. 1 punch press 09, an upsetting die and a forming die are provided on the No. 1 punch press 09. The upsetting die is 5 mm higher than the forming die, and the forming die is ejected by a double tie rod. It should be noted that the design of the upsetting die and the forming die belongs to the prior art for those skilled in the art.

[0024] See also Figure 2 As shown, in order to ensure that the blank can smoothly enter the secondary heating furnace 07, a receiving mechanism 16 and a tailing conveying mechanism 17 are arranged on both sides of the cutting punch 06. The receiving mechanism 16 takes out the blank under the cutting punch 06 or pushes the tailing into the tailing conveying mechanism 17 by electromagnetic suction or vacuum adsorption. A pushing mechanism 18 and a storage chute 19 are arranged on both sides of the receiving mechanism 16. The pushing mechanism 18 is adjacent to the primary heating furnace 05, and the storage chute 19 is adjacent to the secondary heating furnace 07. A feeding mechanism 20 is arranged on one side of the storage chute 19. The feeding mechanism 20 and the secondary heating furnace 07 are located on both sides of the storage chute 19 and arranged in the same plane. After the primary heating furnace 05 heats the bar for the first time, the bar enters the cutting punch 06, the receiving mechanism 16 extends out and is located below the cutting punch 06, the cutting punch 06 performs warm cutting on the bar to form a blank, the blank falls into the receiving mechanism 16, the receiving mechanism 16 is retracted, and the blank in the receiving mechanism 16 is pushed into the storage chute 19 by the pushing mechanism 18. When the blank enters the storage chute 19, the feeding mechanism 20 continuously feeds the single blank into the secondary heating furnace 07 for secondary heating.
