Abstract
The utility model discloses a conductive bearing of welding machine, which comprises a bearing body whose outer side is provided with a mounting hole and a nozzle tip hole, wherein a semi-circular conductive contact face is arranged on the inner side of the bearing body. The conductive bearing is characterized in that the semi-circular conductive contact face and the body is an integrated structure, a groove is arranged on the middle portion of the semi-circular conductive contact face, and one end of the groove is communicated with the nozzle tip hole. The conductive bearing can be widely applied in roll type welding equipment, and solves the problems of expensive price, lower service life, poor performance, impacts on the welding quality, raw material waste and the like of rare metal conductive bearings in welding machines.
Description
Technical field
The utility model relates to a kind of bonding machine with conducting electricity bearing shell.
Background technology
At present, at home, outer color picture tube, automobile, in the manufacturing of industries such as high voltage power transmission transformer, employed roller bonding machine, electric current is flexible coupling through conduction through direct-connected conductive copper plate from transformer again, pass to the welding rotary main shaft again and welding electrode carries out welding job by critical component conduction bearing shell, the bearing shell that wherein conducts electricity is the critical component of electric current conduction, it also is the weakest link of conductive path, the performance of conduction bearing shell directly influences the equipment welding quality, the conduction bearing shell adopts yellow gold as inboard conductive material usually, yellow gold is inlayed to the copper alloy bearing-bush inboard, Kufil costs an arm and a leg, and hardness is low, and serious wear is used in energising, so that bearing shell is low service life, the manufacturing cost height; Occur sparking behind the bearing bush abrasion easily, burn conduction main shaft influences the product welding quality, causes remarkable waste.
Summary of the invention
At existing bonding machine conduction bearing shell manufacturing cost height, daily production process intermediate bushing is hot, and electric conductivity descends, and influences the serious problems of welding quality, and the purpose of this utility model provides a kind of bonding machine novel conductive bearing shell.
For reaching above purpose, the utility model adopts following technical scheme to be achieved:
A kind of bonding machine is with conducting electricity bearing shell, comprise that the outside has the bearing shell body in installing hole and oil nozzle hole, bearing shell body inboard is provided with the semi arch conductive contact surfaces, it is characterized in that, this semi arch conductive contact surfaces and bearing shell body are overall structure, be provided with groove in the middle of this semi arch conductive contact surfaces, groove one end communicates with the oil nozzle hole.
In the such scheme, described overall structure is by the alloy solid solution body of chromium zirconium copper product through the aging precipitation cure process.The hardness of this alloy solid solution body is HRB:62-65, conductance IASCS% 〉=70.
The beneficial effects of the utility model are: bearing shell is set to whole semicircle form, and manufacturing processing technic is simple, and its effective working face thickness increases greatly, and will prolong greatly service life; Adopt bulk material chromium zirconium copper as the working face material, reduce significantly as the inboard conductive material manufacturing cost of bearing shell than yellow gold (AgCu10); Storage conductive grease groove is set, reduces the bearing shell operating temperature, improve the bearing shell electric conductivity, promote the stability that bearing shell uses greatly.
Description of drawings

Fig. 2 is the vertical view of Fig. 1.
Among Fig. 1 Fig. 2: 1: the inboard semi arch conductive contact surfaces of bearing shell; 2: the bearing shell groove; 3: the oil nozzle installing hole; 4: the bearing shell installing hole; 5: the bearing shell body.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in Figure 2 as Fig. 1, the conduction bearing shell is designed to whole semicircle form, the inboard semicircular arc conductive contact surfaces 1 of bearing shell is an one with bearing shell body 5, groove 2 is set in the middle of the semi arch conductive contact surfaces 1, groove one end is connected with the screwed oil nozzle installing hole 3 in the outside, and installing hole 3 installs oil nozzle additional, and the groove other end is not connected with the outside, add special-purpose conductive grease in order to reduce bearing shell friction temperature by grease fitting, improve electric conductivity.Two threaded mounting holes 4 of bearing shell design are used for bearing shell and are flexible coupling with conduction and link to each other with hold-down mechanism; Bush material adopts chromium zirconium copper (CuCr1Zr), make Cr and Zr and Cu form the alloy solid solution body through the aging precipitation cure process, through vacuum melting-forging-cold-drawn-punch forming-age-hardening, make bearing shell hardness reach HRB:62-65, conductance IASCS% 〉=70 again.
During use two bearing shell subtends are used, are utilized the hold-down mechanism in the bearing shell outside that two bearing shell semicircles are linked to each other with the conduction main shaft, with reach electric current from direct-connected copper coin to the rotary main shaft conduction, the utility model can be widely used in the roller welding equipment.
