Abstract
The invention discloses a main roller for producing a special-shaped ring forging piece of a bearing inner ring of a wind power generating unit. The main roller is characterized by comprising three parts of an upper main roller, a middle main roller and a lower main roller. According to the main roller disclosed by the invention, the main roller is convenient to disassemble, the operation of replacing the whole main roller in the prior art is replaced by the operation of just replacing the upper main roller or the lower main roller when the main roller is abraded, the die materials are effectively saved, the working efficiency is increased, and the production period is shortened; the main roller is mainly used for producing the special-shaped ring forging piece of the bearing inner ring of the wind power generating unit.
Description
Technical field
the present invention relates to a kind of home roll of producing forging special-shape ring, particularly related to a kind of home roll for the production of wind power generating set bearing inner race forging special-shape ring.
Background technology
bearing inner race is the key components and parts that ensures that generating set can better turn round, because it is for a long time under the rotating environment in top load, so necessarily require bearing inner race to possess very strong wearability, good mechanical property, in order to meet these performance needs of bearing inner race, generally adopt looping mill rolling to form.
because the structure of bearing inner race is comparatively complicated, first being rolled into rectangle ring if adopt is machined into bearing inner race again and is cut off in a large number, cause the performance of bearer ring to reduce, affect the service life of generator, and need machine to add to fall metal material greatly, cause stock utilization high, waste of material is serious.So for the shaping of bearing inner race, generally adopt special-shaped ring rolling.Respectively there is a boss at the two ends of bearing inner race forging special-shape ring external diameter, and in the time that this boss is shaped, home roll is exerted pressure to it, and the pressure that corresponding boss corner positions is born on home roll is large, serious wear.Often need to change whole home roll because this place is worn, waste is serious, and will again make home roll, has extended the production cycle, is unfavorable for batch production.
Summary of the invention
the technical problem to be solved in the present invention is to provide a kind of easy-to-dismount combined type home roll and carrys out production wind power generating set bearing inner race forging special-shape ring, improves the bulk life time of home roll, shortens the production cycle.
for solving the problems of the technologies described above, the home roll for the production of wind power generating set bearing inner race forging special-shape ring of the present invention, is characterized in that, comprises home roll, middle home roll and three parts of lower home roll.
further, described upper home roll, middle home roll and lower home roll are with bolts forming.
further, the external diameter height of described upper home roll and lower home roll accounts for respectively 20% ~ 30% of home roll total height.
further, the external diameter profile of described upper home roll, middle home roll and lower home roll is conjugation shape with the corresponding position profile of bearing inner race forging special-shape ring external diameter respectively.
further, described upper home roll, middle home roll and lower home roll all have dovetail groove.
Compared with prior art, beneficial effect of the present invention is as follows:
home roll for the production of wind power generating set bearing inner race forging special-shape ring of the present invention, comprises home roll, middle home roll and three parts of lower home roll.Bearing inner race forging special-shape ring upper/lower terminal boss and bight be corresponding upper home roll and lower home roll respectively, and this position is because the pressure bearing is large, and serious wear, need to often change.The present invention, by only replacing with home roll or lower home roll, replaces in prior art and changes overall home roll, has effectively saved mold materials, increases work efficiency, and has shortened the production cycle.
Brief description of the drawings
below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
fig. 1 is bearing inner race annular forging piece structural representation schematic diagram;
fig. 2 is the main perspective cutaway view of home roll;
fig. 3 is the top view of home roll.
Detailed description of the invention
for implementing better the present invention, wind power generating set bearer ring inner ring annular forging piece 6 need be provided, as shown in Figure 1, respectively there is a boss at the two ends of bearing inner race forging special-shape ring 6 external diameters to its structure, and the height of boss accounts for 15% of bearing inner race forging special-shape ring 6 total heights.
home roll for the production of wind power generating set bearing inner race forging special-shape ring of the present invention, according to bearing inner race forging special-shape ring 6 structural designs, the material selection mould steel 5CrNiMo of home roll, home roll is made up of upper home roll 1, middle home roll 2 and lower home roll 3.Design respectively six screwed holes at upper home roll 1, middle home roll 2 and lower home roll 3, upper home roll 1, middle home roll 2 and lower home roll 3 can have been coupled together by bolt 4, for convenience detach; The external diameter height of described upper home roll 1 and lower home roll 3 accounts for respectively 25% of home roll total height, ensures the part of bearing inner race forging special-shape ring 6 external diameter two ends band boss, is formed respectively by upper home roll 1 and lower home roll 3 rollings; The external diameter profile of described upper home roll 1, middle home roll 2 and lower home roll 3 is conjugation shape with the corresponding position profile of bearing inner race forging special-shape ring 6 external diameters respectively; Described upper home roll 1, middle home roll 2 and lower home roll 3 all have six corresponding dovetail grooves, for the driving shaft of connecting ring milling train.
