Abstract

The utility model belongs to the improvement of high-frequency straight seam welded pipe set structure, a kind of improved high-frequency straight seam welded pipe unit edger roll structure particularly, be included in affixed vertical roll shaft on edger roll seat, on vertical roll shaft, by bearing, edger roll is installed, in the plane of edger roll, arranging and take the ring groove that edger roll axle center is the center of circle, in vertical roll shaft upper end, by nut, the labyrinth type packing ring that periphery has lower convex ring is installed, at the lower convex ring of labyrinth type packing ring, matches with the ring groove of plane on edger roll.The utility model compact conformation, water proof and dust proof performance is good, and the good seal performance of bearing can extend service life of bearing, reduces production costs.

Description

Improved high-frequency straight seam welded pipe unit edger roll structure

Technical field

The utility model belongs to the improvement of high-frequency straight seam welded pipe set structure, particularly a kind of improved high-frequency straight seam welded pipe unit edger roll structure.

Background technology

At present, high-frequency straight seam welded pipe unit, according to the assembling mode of roll, can be divided into horizontal roller, edger roll, and edger roll assembling mode normally edger roll is rotated and vertical roll shaft does not rotate, and bearing is contained on edger roll conventionally.And high-frequency straight seam welded pipe is when produce, due to the stressed and pivoting friction of edger roll, make edger roll when producing, usually make water cooling to edger roll, due to the problem of edger roll assembly structure at present, inevitably cause the poor sealing of bearing, bearing damage is serious.Bearing Consumption when ratio-frequency welded tube is produced is a key factor of production cost.

Utility model content

The purpose of this utility model is to provide a kind of improved high-frequency straight seam welded pipe unit edger roll structure, its compact conformation, and water proof and dust proof performance is good, and the good seal performance of bearing can extend service life of bearing, reduces production costs.

The purpose of this utility model is achieved in that an improved high-frequency straight seam welded pipe unit edger roll structure, be included in affixed vertical roll shaft on edger roll seat, on vertical roll shaft, by bearing, edger roll is installed, in the plane of edger roll, arranging and take the ring groove that edger roll axle center is the center of circle, in vertical roll shaft upper end, by nut, the labyrinth type packing ring that periphery has lower convex ring is installed, at the lower convex ring of labyrinth type packing ring, matches with the ring groove of plane on edger roll.

In order to solve the shortcoming of former high-frequency straight seam welded pipe unit edger roll structurally waterproof poor performance, designed the edger roll structure with labyrinth waterproof structure, upper planar design at edger roll circularizes groove, original gasket design is become to the labyrinth type packing ring with edger roll cannelure with matched in clearance, when cooling water is splashed into edger roll cannelure, due to the effect in labyrinth, cooling water can not be entered in bearing, labyrinth type packing ring has dust reduction capability.So high-frequency straight seam welded pipe unit edger roll structure has the effect of water proof and dust proof after improving, it can make production cost greatly reduce.

The utility model compact conformation, water proof and dust proof performance is good, makes the good seal performance of bearing, has extended the service life of bearing, has reduced production cost.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is sectional structure schematic diagram of the present utility model.

The specific embodiment

A kind of improved high-frequency straight seam welded pipe unit edger roll structure, as shown in Figure 1, be included in affixed vertical roll shaft 4 on edger roll seat 6, on vertical roll shaft 4, by bearing 5, edger roll 1 is installed, in the plane of edger roll 1, arranging and take the ring groove that edger roll axle center is the center of circle, in vertical roll shaft 4 upper ends, by nut 3, the labyrinth type packing ring 2 that periphery has lower convex ring is installed, at the lower convex ring of labyrinth type packing ring 2, matches with the ring groove of plane on edger roll 1.

Claims

1. an improved high-frequency straight seam welded pipe unit edger roll structure, be included in upper affixed the vertical roll shaft (4) of edger roll seat (6), at vertical roll shaft (4), above by bearing (5), edger roll (1) is installed, it is characterized in that: in the plane of edger roll (1), arranging and take the ring groove that edger roll axle center is the center of circle, in vertical roll shaft (4) upper end, by nut (3), the labyrinth type packing ring (2) that periphery has lower convex ring is installed, the ring groove of going up plane with edger roll (1) at the lower convex ring of labyrinth type packing ring (2) matches.
