Description

Technical Field

[0001] The utility model relates to the field of bearing needle roller processing, in particular to a bearing needle roller processing raw material cutting device. Background Art

[0002] At present, a Chinese utility model with announcement number CN213856825U discloses a cutting device for processing needle rollers of automobile parts bearings, including a cutting platform, on the bottom surface of which a supporting leg is fixedly connected; through the cooperation of a first pressure device and a corresponding clamping device, the holding force of the clamping device on the raw steel wire is proportional to the tensioning force provided by the tensioning roller for the raw steel wire. The greater the tension, the greater the holding force, and the greater the friction between the clamping device and the raw steel wire. This ensures that when the tension provided by the tensioning roller for the raw steel wire is large, the raw steel wire will not slide relative to the clamping device during the process of the first pressure device and the clamping device cooperating to pull the raw steel wire to the right, thereby ensuring that the pulling stress borne by the raw steel wire itself is large enough to completely straighten the raw steel wire, thereby improving the quality of the needle roller product and improving the practicality of the cutting device for processing needle rollers of automobile parts bearings.

[0003] The existing cutting device cannot cut bearing needle roller raw materials of different coarsenesses. The size of the threading holes on the cutting table of the general cutting device is fixed, and it can only be used for bearing needle roller raw materials of one coarseness. If it is necessary to use bearing needle roller raw materials of different coarsenesses, the cutting table needs to be replaced, and the replacement of the cutting table is rather cumbersome, which not only increases the workload, but also increases the processing cost. It is inconvenient to use and it is not convenient to replace the cutting knife. The cutting knife of the general cutting device needs to be replaced after long-term use, and the cutting knife is generally fixed to the fixing seat by multiple bolts. When replacing, tools are needed to disassemble and assemble it. The disassembly and assembly process is very troublesome, which increases the workload and reduces the replacement efficiency. In order to solve the above-mentioned problems, we propose a bearing needle roller processing raw material cutting device. Utility Model Content
