Abstract
The invention discloses a bearing forging spreading roller with a front support. The bearing forging spreading roller comprises a spreading roller body, wherein a bearing forging is sleeved on the spreading roller body, and is externally provided with a spreading wheel for driving the bearing forging and the spreading roller body to rotate simultaneously; a front end of the spreading roller body is fixed on a support seat in a rotating way; and a rear end of the spreading roller body is matched with a top sleeve in a shell in a rotating way. Through structural designs of the support seat, the shell and the top sleeve, the rigidity of the spreading roller body can be effectively improved, the taper of a spreading and expanding piece is favorably eliminated, the product quality can be ensured easily, and the spreading roller is not easy to break off.
Description
Technical field
The invention belongs to bearing manufacturing technology field, be specifically related to a kind of bearing ring that is used for and roll over the preceding supporting of the spreading roller strap that expands.
Background technology
In the Production of bearing process, longer because of the calendering roller cantilever when needs are rolled over the bigger lasso of degree of widening, roll over that lasso is easy to generate big tapering when expanding, difficult quality guarantee, the strain problem is more outstanding, and calendering roller also fractures easily.Not only have influence on production efficiency, also had a strong impact on the product quality of big width lasso.
Summary of the invention
The deficiency that technology is arranged on the objective of the invention is to overcome provides a kind of band simple in structure, easy to operate, that can effectively guarantee big width lasso quality the preceding bearing forging calendering roller that supports.
A kind of with before the bearing forging calendering roller of supporting, comprise the spreading roll body, the bearing forging is sleeved on the spreading roll body, the bearing forging is provided with outward and drives the roll milling wheel that bearing forging, spreading roll body rotate simultaneously; The front end rotational fixation of said spreading roll body is on supporting base, and the rear end is overlapped rotation with the top in the housing and cooperated.
The present invention can effectively improve the rigidity of spreading roll body through the structural design of supporting base and housing, top cover, grinds the tapering that expands part good effect is arranged eliminating, and product quality is guaranteed easily, and calendering roller is frangible not.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Referring to Fig. 1, provided by the invention a kind of with before the bearing forging calendering roller of supporting, comprise spreading roll body 1, bearing forging 2 is sleeved on the spreading roll body 1, bearing forging 2 is outer to be provided with and to drive the roll milling wheel 3 that bearing forging 2, spreading roll body 1 rotate simultaneously; The front end rotational fixation of said spreading roll body 1 is on supporting base 4, and the rear end is overlapped 6 rotations with the top in the housing 5 and cooperated.
Claims (1)
1. the bearing forging calendering roller of supporting before the band; Comprise the spreading roll body; The bearing forging is sleeved on the spreading roll body; The bearing forging is provided with outward and drives the roll milling wheel that bearing forging, spreading roll body rotate simultaneously, it is characterized in that: the front end rotational fixation of said spreading roll body is on supporting base, and the rear end rotates with top cover in the housing and cooperates.
