Description

Technical Field

[0001] The utility model relates to the field of straightening and cutting equipment, in particular to a bearing needle roller production device. Background Art

[0002] The needle roller is an important component of the needle roller bearing. It is a roller bearing with cylindrical rollers. Relative to its diameter, the roller is both thin and long. When producing the needle roller, a straightening and cutting device is required to straighten and quantitatively cut the selected materials such as steel bars or metal wires.

[0003] At present, the Chinese utility model with the announcement number CN213826785U discloses a straightening and cutting device for metal wire processing, including a straightening device, a cutting device and a grating sensor; the straightening device includes a plurality of straightening wheels and a driving motor; the straightening wheels are arranged in parallel on the positive end face of the straightening device; the driving motor is arranged behind the straightening device and connected to the straightening wheels; the cutting device is closely arranged on one side of the straightening device; the cutting device includes a cutter lifting mechanism, a cutter and a cutter groove; the cutter is connected below the cutter lifting mechanism; the cutter groove is arranged at the top of the cutting device and is located directly below the cutter; the grating sensor is arranged on both sides of the top of the cutting device; the grating sensor is divided into a transmitting end and a receiving end. The utility model uses the characteristics of the large range and high precision of the grating sensor to measure the length of the metal wire and convert it into an electrical signal so that the control system can control the cutter to cut the metal wire, with high efficiency and high degree of automation.

[0004] To sum up, although the straightening and cutting device can achieve the functions of straightening and quantitative cutting, there are still certain problems when using it. For example, the structure of the straightening and cutting device for straightening the material lacks an adjustable structure, and it can only be applied to materials of the same diameter size, and cannot be applied to metal materials of different coarse and fine sizes for clamping and straightening, and its applicability is poor. At the same time, the straightening and cutting device, its cutter and lifting mechanism lack a quick-disassembly structure, and the cutter will produce certain wear when cutting the metal material. Therefore, the cutter needs to be replaced frequently after long-term use. The straightening and cutting device cannot quickly replace the cutter, resulting in a decrease in the work efficiency of cutting the metal material. Utility Model Content
