The invention provides a roller hot rolling machine and a hole pattern roller. The hole pattern roller comprises a roller body, wherein the side wall of the roller body is provided with helical convex ribs, every two adjacent convex ribs form a roller hole pattern with the outer wall of the roller body, and one side of each convex rib is provided with a storage groove. The hot rolling machine comprises a drive device and a machine body, wherein one side of a feeding end of the machine body is provided with a material wheel and a heating furnace, the discharging end of the machine body is provided with a material passage, two universal joint transmission devices are driven by the drive device to rotate, the two universal joint transmission devices are respectively connected with a main shaft of a cylindrical roller and a main shaft of the hole pattern roller, the cylindrical roller is arranged on the machine body through a cylindrical roller bearing seat, and the hole pattern roller is arranged on the machine body through a hole pattern roller bearing seat. Compared with the prior art, the roller hot rolling machine has the beneficial effects that the production efficiency can be improved, and raw materials can be saved.
Description
technical field [0001] The invention relates to the technical field of bearing manufacture, in particular to a hot rolling mill for processing roller bearings, and also to a grooved roll used in the hot rolling mill. Background technique [0002] Roller bearings are a very common series of bearings, mainly divided into cylindrical rollers, spherical rollers and tapered rollers. These rollers are mainly processed by lathe turning or press upsetting. In different roller processes, these two types of methods have their own advantages and disadvantages: [0003] 1. Processing of cylindrical rollers [0004] 1. The lathe turning process is as follows: the cylindrical bar is cut according to the diameter of the roller and the outer diameter of the roller is cut off according to the length of the roller. The problem with this kind of lathe processing is: [0005] (1) Low production efficiency. For example, diameter For cylindrical rollers with a length of 24mm, a lathe can pr...
