Abstract
The utility model discloses an improved bearing ring forging roll. A reinforced section is arranged in the joint of the head and the tail part of the roll; and smooth transition is adopted at the joint of the reinforced section and a cylinder on the head, as well as the reinforced section and a conical step on the tail part of the roll. By arranging a reinforced section in the middle of the roll without enlarging the diameter of the punch head of the roll, the improved bearing ring forging roll can effectively enhance intensity, prolong service life of the roll, improve product quality and production efficiency, reduce replacement frequency, lower manual work intensity and save cost.
Description
Technical field
The utility model relates to a kind of roll, the roll that is used for the bearing ring forging that particularly a kind of middle part is strengthened.
Background technology
Roll is one of machinery manufacturing industry equipment commonly used, and the life-span of roll is the key that influences product quality, production efficiency and manual working intensity, and therefore, breaker roll has relatively high expectations in the production process.When roll is too hard, be difficult for fusing and oxidation in process of production, but frangibility; When roll is too soft, then yielding in process of production and oxidation.In the forging process of medium-and-large-sized bearing ring, generally in the scope of 500-1000 spare, when running into abnormal conditions, the service life of roll is shorter for the roll campaign in the industry at present.Therefore, providing a kind of roll of long service life is the problem that this area needs to be resolved hurrily.
The utility model content
The purpose of this utility model provides a kind of roll that bearing ring forges that is used for of long service life.
The roll that is used for the bearing ring forging has substantial connection with following 4 service life usually: material, annealing quenching technical, ream operation and geometry.No. 45 steel of roll employing or the bearing steel that generally use in the industry at present process, service life is still undesirable, if adopt 3Cr2W8Vi mould steel, though then prolong relatively the service life of roll, but its price is more than 8 times of above-mentioned two kinds of firm materials, and cost performance is undesirable.For annealing and quenching technical, employed technology and equipment is mature on the whole in the industry at present, promote again, needs the huge input of cost.Ream operation depends on manual operation basically, and is relevant with operating experience.According to observation in the actual production and analysis, find that roll long most important reason in service life is not anneal oxidation deliquescing under the high temperature, but from middle this section of roll, reason is that roller head tail joint portion intensity is less than normal.Therefore, the life-span of improving roll by the geometry that changes roll is effective and the most economical and the most practical method at present.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of modified bearing ring forging roller is provided with the reinforcement section at the head of roll and the junction of afterbody.
The head of described roll is a cylinder, and described afterbody is a frustum, strengthens section and adopts rounding off between the two.
The beneficial effects of the utility model are, the setting of the reinforcement section by head and afterbody junction, do not increasing the roll punch diameter and do not increasing under the prerequisite of cost, effectively increased intensity, life-span of the present utility model is prolonged greatly, thereby reduced the replacing frequency of roll, improved product quality, reduced production cost and hand labor intensity.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structure chart of the described improved roll of the utility model embodiment.
Among the figure:
1, roll afterbody; 2, roll head; 3, strengthen section.
The specific embodiment
As shown in Figure 1, the described modified bearing ring of the utility model embodiment forging roller is strengthened section 3 in the junction of roll head 2 and roll afterbody 1 by being provided with, and whole roll is strengthened in local overstriking; Described roll head 2 is cylinders, and described roll afterbody 1 is the frustum of a cone, strengthens section 3 and adopts rounding off between the two.
Claims (2)
1. a modified bearing ring forging roller is characterized in that, at the head of roll and the junction of afterbody the reinforcement section is set.
2. modified bearing ring forging roller according to claim 1 is characterized in that the head of described roll is a cylinder, and described afterbody is a frustum, strengthens section and adopts rounding off between the two.
