The wheel boss rotor is supported on a shaft of the stator via an end cover and a bearing. At least one conductive spring sheet is arranged between the wheel boss and the shaft of the stator. In the welding wheel, the conductive spring sheet is used for conducting current in the form of an electric brush. The utility model has the advantages of simple structure and good water-cooling effect. The working temperature of the welding wheel is low, and the load capacity of the welding wheel is raised.
Description
The utility model relates to a kind of weldering wheel of electric-resistance seam-welding machine
In the prior art, the weldering of electric-resistance seam-welding machine wheel is a pouring in liquid metal in stator and gap between rotor, and electric current conducts to stator by liquid metal from rotor during welding.Liquid metal commonly used is a mercury, and it is harmful to health, and mercury is easy and other metal produces chemical reaction.Therefore, the weldering of pouring in liquid metal wheel is replaced by a kind of sliding-contact formula weldering wheel.Chinese invention patent " roller head for resistance seam-welding machine " (patent No. ZL92101554.2, notification number CN1023302C) is exactly a kind of sliding-contact formula weldering wheel, its electric installation is to be pressed on the stator faces by two disks, with braid over braid disk is connected with rotor flexibility, produce axial pressing force with butterfly spring, during the rotor rotation, this two disks and stator faces sliding-contact, form current path, the weldering wheel of this structure has had significant improvement than the weldering wheel of pouring in liquid metal, but its structure more complicated, the inner sliding contact surface of weldering wheel can not get effective cooling, cause the temperature rise of weldering wheel higher, load capacity reduces.
The purpose of this utility model is: the novel weldering wheel that a kind of electric-resistance seam-welding machine is provided, this weldering wheel comes conductive electric current with conductive spring leaf as the form of brush, and is not only simple in structure, and good water-cooled effect is arranged, the operating temperature of weldering wheel is low, and load capacity is improved.
The technical solution of the utility model is: a kind of novel weldering wheel of electric-resistance seam-welding machine, comprise rotor and stator, and the wheel hub of rotor on stator axis, is provided with a slice conductive spring leaf by end cap and bearings at least between described wheel hub and the stator axis.
The further technical scheme of the utility model is: a kind of novel weldering wheel of electric-resistance seam-welding machine comprises having changeed and stator that the wheel hub of rotor on stator axis, is provided with a slice conductive spring leaf by end cap and bearings at least between described wheel hub and the stator axis; One end of described conductive spring leaf is fixed on one of the external cylindrical surface of stator axis and inner cylinder face of wheel hub, and the other end of conductive spring leaf is conflicted on another face of cylinder; Described conductive spring leaf makes it produce contact pressure to the face that is contacted along the equidirectional bending.
The optimal technical scheme of the utility model is: a kind of novel weldering wheel of electric-resistance seam-welding machine, comprise rotor and stator, and the wheel hub of rotor on stator axis, is provided with a slice conductive spring leaf by end cap and bearings at least between described wheel hub and the stator axis; One end of described conductive spring leaf is fixed on one of the external cylindrical surface of stator axis and inner cylinder face of wheel hub, and the other end of conductive spring leaf is conflicted on another face of cylinder; Described conductive spring leaf makes it produce contact pressure to the face that is contacted along the equidirectional bending; The two ends of described stator axis are provided with cooling water hole, and communicate with gap between wheel hub and the stator axis by the connecting hole radially offering and stagger respectively at the middle part of stator axis.
The utility model has the advantages that:
1. the utility model utilizes conductive spring leaf as conductor, cans be compared to the brush of installing between rotor and stator, simultaneously, itself has elasticity conductive spring leaf, it has played the effect of holddown spring again, thereby makes whole weldering wheel reduce number of spare parts, has simplified the weldering wheel construction.
2. the utility model is provided with cooling water hole, and the area of dissipation of conductive spring leaf is very big again, and parallel with the cooling water flow direction, and the resistance of cooling water flow is reduced, and the inner heating part of weldering wheel is fully cooled off, thereby has reduced temperature rise, has improved load capacity.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the profile of Fig. 1;
Wherein: 1 wheel hub; 2 end caps; 3 bearings; 4 stator axis; 5 conductive spring leafs; 6 cooling water holes; 7 connecting holes; 8 seals.
