Embodiment Construction

[0012] In order to gain an in-depth understanding of this preforming die for machining straight tall cylindrical forgings, combined with figure 1 , 2 described as follows:

[0013] It mainly includes: a base 1, a V-shaped opening 2 and a side slope 3. The front end of the base 1 is provided with a V-shaped opening 2, and the V-shaped opening 2 is composed of slopes 3 on both sides; the V-shaped opening 2 is 112°, and the inclination angle of the circular table The method of use is as follows: Put the mandrel in, then place the bearing ring flatly on the mold, the outer circle of the ring is in contact with the 3° inclined surface 3 of the abrasive tool, supported by the 112° V-shaped opening 2 , and then apply the gravity hammer of the air hammer to make the forging reach the height required by the process and form a conical forging.

Abstract

The invention relates to a die, in particular to a pre-forming die for processing straight-height cylindrical forgings, which belongs to the field of bearing parts processing equipment. In the preforming die used for processing straight-height cylindrical forgings provided by the present invention, the V-shaped opening is formed by two side baffles; the V-shaped opening is 112°, and the blank ring is finally formed into a circular frustum, and the inclination angle of the circular frustum is 3°, the blank ring does not move outwards and moves inwards, which solves the problems of rolling end face depressions and burrs, improves the yield and production efficiency, and reduces the cost of the product.

Description

technical field [0001] The invention relates to a die, in particular to a pre-forming die for processing straight-height cylindrical forgings, which belongs to the field of bearing parts processing equipment. Background technique [0002] Rolling bearing is a precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings generally consist of outer rings, inner rings, rolling elements and cages. According to the type of rolling element, the bearing is divided into: ball bearing - the rolling element is a ball; roller bearing - the rolling element is a roller, and the roller bearing is divided into: cylindrical roller bearing - the rolling element is a cylinder Roller bearings, the ratio of the length to diameter of cylindrical rollers is less than or equal to 3; needle roller bearings - rolling elements are needle roller bearings, the ratio of the length to dia...
