Abstract
The utility model provides a spindle supporting device of a steel tube head manufacturing machine, and relates to the steel tube head manufacturing machine, in particular to a spindle supporting device of the head manufacturing machine. The spindle supporting device comprises a bearing seat box body and a spindle, wherein the spindle is supported in the bearing seat box body through three groups of bearings; and one group of the bearings is sleeved at one end of the spindle, and the other two groups of the bearings are sleeved at the other end of the spindle. The spindle supporting device has the advantages of simple, reasonable and compact structure and high spindle strength, is mounted on the steel tube head manufacturing machine, improves the cold-drawn steel tube head manufacturing accuracy and efficiency, can be widely used for manufacturing heads of middle-and-large caliber cold-drawn seamless steel tubes, is particularly suitable for a large-tonnage hydraulic cold drawing machine to produce seamless steel tubes, and has high popularization value.
Description
Technical field
The utility model relates to a kind of steel pipe system machine, relates in particular to the Main axis surpporting device of a system machine.
Background technology
A steel pipe system machine is applicable to the solid drawn tube industry, especially for middle heavy caliber solid drawn tube industry, is mainly used in the steel pipe head system head of steel pipe before cold-drawn.Existing cold drawn steel control head apparatus is mainly used pneumatic hammer, board drop hammer, rotary forging machine, and its complex structure, a system precision is low, and made steel pipe head pricked extremely, make troubles for the processing of road, back, and made head is longer, and metal loss is big.For middle large diameter steel pipe, existing system head apparatus is powerless.
The utility model content
The purpose of this utility model mainly provides a kind of Main axis surpporting device of a steel pipe system machine simple in structure, easy to use.
The purpose of this utility model is achieved in that the Main axis surpporting device of a kind of steel pipe system machine, comprise bearing block casing and main shaft, in the bearing block casing, wherein one group of bearing is nested with the end at main shaft, other two groups of other ends that are nested with at main shaft to main shaft by three groups of bearings.
The simple and reasonable compactness of the utility model, the main shaft stiffness is strong, is installed on the steel pipe system machine, the precision and the efficient of cold drawn steel control head have been improved, the system head of heavy caliber cold-drawing seamless pipe in can being widely used in, particularly suitable large-tonnage hydraulic pressure cold drawing machine is produced seamless steel pipe, has excellent popularization to be worth.
The outer end that wherein is arranged on the bearing of outer end in described three groups of bearings is provided with bearing (ball) cover respectively, and each bearing (ball) cover is fixedlyed connected with the bearing block casing respectively.
The bearing that wherein is provided with one group in described three groups of bearings is a single-row tapered roller bearing, and the bearing that is provided with two groups is respectively single-row tapered roller bearing and double-row self-aligning roller bearing.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As Fig. 1, shown in, Main axis surpporting device for a steel pipe system machine, comprise bearing block casing 7 and main shaft 5, main shaft 5 is supported in the bearing block casing 7 by first single-row tapered roller bearing 8, second single-row tapered roller bearing 9 and biserial roller self-aligning bearing 10, wherein first single-row tapered roller bearing 8 is nested with the end at main shaft 5, the other end that second single-row tapered roller bearing 9 and biserial roller self-aligning bearing 10 are nested with at main shaft 5.The outer end of first single-row tapered roller bearing 8 and biserial roller self-aligning bearing 10 is provided with bearing (ball) cover 6 respectively, and each bearing (ball) cover 6 is fixedlyed connected with bearing block casing 7 by hex bolts respectively.
