Abstract
The utility model discloses an axial rolling mechanism for a flange ring rolling mill. The axial rolling mechanism comprises a workbench, wherein a movable machine frame is arranged on the workbench; a rolling air cylinder is arranged on the top of the movable machine frame and is connected with an upper conical roller box body; the upper conical roller box body is connected with the movable machine frame by a guide rod; an upper conical roller is arranged on the upper conical roller box body; a lower conical roller is arranged on the lower part of the movable machine frame; a taper angle alpha 1 of the upper conical roller and a taper angle alpha 2 of the lower conical roller are 18 to 30 degrees; and wear-resisting sleeves are inlaid into the surfaces of the upper conical roller and the lower conical roller. By the axial rolling mechanism for the flange ring rolling mill, friction force between the upper conical roller and the lower conical roller and workpieces can be effectively reduced; and the wear-resisting sleeves also can relieve the abrasive condition of the conical rollers, so that the service life of the conical rollers can be prolonged by more than 50 percent, the production efficiency of enterprises is improved, and the production cost of the enterprises is saved.
Description
Technical field
The utility model relates to a kind of process equipment of flange ring, is specifically related to a kind of axially rolled mechanism of flange ring milling train.
Background technology
The flange ring milling train is when work, and the roller of awl up and down in the axially rolled mechanism contacts with workpiece and rotates, and linear velocity is increased by the center of circle to external diameter gradually during the workpiece rotation; When contacting with the awl roller, the linear velocity of each point is all inconsistent on the contact-making surface, therefore; Can produce frictional force between awl roller and the workpiece, the service life of roller, employed awl roller on the existing flange ring ring machine are bored in the direct influence of the size of this frictional force up and down; The cone angle of its epicone roller and following awl roller is generally speaking all greater than 45 °, and the linear velocity difference the during rotation of awl roller between top and the bottom is bigger, can cause boring producing bigger frictional force when roller contacts with workpiece; Accelerate the abrasion condition of awl roller, influenced the service life of awl roller, needed often to change the awl roller in the production; Influence the production efficiency of enterprise, and increased the production cost of enterprise.
The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art, and a kind of axially rolled mechanism of flange ring milling train is provided, and it can effectively reduce the frictional force between awl roller and the workpiece, alleviates the situation of awl roller wearing and tearing, prolongs the service life of awl roller.
For realizing above-mentioned purpose, the technical scheme of the utility model is the axially rolled mechanism of a kind of flange ring milling train of design, and said rolling mechanism comprises workbench; It is characterized in that; Installation and moving frame on said workbench is installed rolling cylinder at said moving frame top, and said rolling cylinder is connected with upper tapered roller box body; Said upper tapered roller box body is connected with moving frame through guide rod; The epicone roller is installed on said upper tapered roller box body, awl roller down is installed, the cone angle of said epicone roller in the bottom of said moving frame
1With the cone angle of boring roller down
2Angle be 18 °～30 °, be inlaid with wear-resistant sleeve on the said epicone roller and the following surface of awl roller.
Wherein optimized technical scheme is, the cone angle of said epicone roller
1With the cone angle of boring roller down
1Its angle is 26 °.
The advantage and the beneficial effect of the utility model are: the axially rolled mechanism of this flange ring milling train can effectively reduce the epicone roller and bore the frictional force between roller and the workpiece down; Wear-resistant sleeve also can alleviate the situation of awl roller wearing and tearing simultaneously; The service life that can prolong the awl roller is more than 50%; Improve the production efficiency of enterprise, practiced thrift the production cost of enterprise.
Description of drawings
Fig. 1 is the structural representation of the axially rolled mechanism of the utility model flange ring milling train;
Fig. 2 is the axially rolled mechanism ring rolling process sketch map of the utility model flange ring milling train.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
Like Fig. 1, shown in 2, the utility model is a kind of axially rolled mechanism of said flange ring milling train, and this mechanism comprises workbench 1; Moving frame 2 is installed on workbench 1, at moving frame 2 tops rolling cylinder 3 is installed, rolling cylinder 3 is connected with upper tapered roller box body 5; Upper tapered roller box body 5 is connected with moving frame 2 through guide rod 8; Epicone roller 6 is installed, awl roller 4 under installing in moving frame 2 bottoms, the cone angle of epicone roller 6 on upper tapered roller box body 5
1With the cone angle of boring roller 4 down
2Angle be 18 °～30 °, be inlaid with wear-resistant sleeve on the said epicone roller 6 and the surface of awl roller 4 down.The awl roller angle that is adopted during actual the use can confirm that the inside and outside electrical path length gap of workpiece 7 is big more according to the size of workpiece 7, and linear differential is big more apart from just; Therefore the angle that needs to increase cone angle increases the gap of boring linear velocity between roller top and the bottom; Frictional force when minimizing awl roller contacts with workpiece 7, if but the angle of cone angle is excessive, above 30 °; The gap that can make linear velocity between awl roller top and the bottom causes frictional force to increase greater than the linear differential distance between the external diameter in the workpiece 7; If the inside and outside electrical path length gap of workpiece 7 is less; Then linear differential is apart from also less, and the angle that therefore needs to reduce cone angle reduces the gap of linear velocity between awl roller top and the bottom, the frictional force in the time of can reducing the awl roller equally and contact with workpiece 7; If but the angle too small of cone angle; Less than 18 °, can make then that the linear differential between the external diameters can cause frictional force to increase apart from the gap greater than linear velocity between awl roller top and the bottom equally in the workpiece 7.
The cone angle of the described epicone roller 6 of the utility model
1With the cone angle of boring roller 4 down
2Preferred angle is 26 °, adopts 26 ° cone angle can take into account the workpiece 7 of various sizes, when the workpiece 7 of the various different sizes of production, does not need to change the awl roller repeatedly, and has wearability preferably.
29 is home rolls among the figure, the 10th, and the core roller.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
