Description
Technical field
It the utility model is related to a kind of mining machinery, specifically a kind of drilling rod shape tube for mining machinery.
Background technology
The application of steel tubes is increasingly valued by people at present, be widely used in vehicle, ship, agricultural machinery,
In the industries such as engineering machinery, textile machine, food machinery.And the place of shape tube is used in the drilling rod of various engineering machinery
Also it is more and more more.Because steel tubes are opening-closed sectional material brake formings under cold state of cold roll forming, shape tube has section
The about energy, save metal material, it is easy for construction, handsome in appearance the advantages that, in recent years more substitute angle steel, channel-section steel, I-steel
And pipe, it is widely used in various building structure, mechanical facility.
The engineering machinery drilling rod profile of early stage is fairly simple, the form that profile lines are combined using straight line with corner angle more, but
With advances in technology with the raising of manufacturing technology level and the introducing of aesthetics design theory, the profile of engineering machinery drilling rod is
Become via the linear pattern of early stage and turn to arc line shaped, its skeleton structure gradually starts large-scale use clod wash steel tubes instead of original
The structure for using the weldings such as square tube, pipe to form to reach effect, because cold-forming shapes are a kind of economic section section bars, it
Complex sections can be molded, and framework is made using profile shapes, vehicle is elegant in appearance, reduces cost, any surface finish, chi
Very little precision is high, and its section modulus is big, antitorque, shock resistance is good, the good excellent functional characteristic of stability, and personalization is fixed
The cold-forming shapes of system obtain widely using in engineering machinery drilling rod manufactures.
Nowadays the drilling rod of mining machinery is spliced using steel construction, and manufacturing process is more, and the production cycle is longer, manufacture
Cost often remains high.
Utility model content
The utility model purpose is to provide a kind of drilling rod shape tube for mining machinery, and it passes through the structure of uniqueness, drop
Low cost, any surface finish, dimensional accuracy are high, and its section modulus is big, have stronger antitorque, impact resistance and stably
Property.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of drilling rod shape tube for mining machinery, including body, the body section are by the first leg and second
Leg forms, and first leg is circle, and second leg is ellipse, and first leg is provided with opening, described
Second leg is arranged on the inside of the first leg, and one end of the second leg is connected with the opening arc transition on the first leg, the
The other end of two legs and the first leg are tangent.
Further, the radius of first leg is 14mm.
Further, the openings of sizes on first leg is 15.47mm.
Further, the transition arc radius that one end of second leg is connected with opening is 3.5mm.
Further, the drilling rod abnormal shape tube thickness of mining machinery is 2.1mm.
Further, material selected by the drilling rod shape tube of mining machinery is Q235.
The beneficial effects of the utility model are：
A kind of drilling rod shape tube for mining machinery provided by the utility model, the utility model pipe meet multiple functions
Property, have intensity high, bending resistance and anti-twisting property are strong, improve the intensity of drilling rod, save material.
