Wheel-type electrode for welding machine

Abstract

The invention discloses a wheel-type electrode for a welding machine, relating to the technical field of manufacturing of welding machines, in particular to an improved wheel-type electrode of the welding machine. The wheel-type electrode comprises a wheel shaft, a wheel body and a welded plate, wherein the wheel body and the welded plate are sleeved on the wheel shaft respectively; the wheel body is fixed on the front part of the wheel shaft; the welded plate is connected to the back part of the wheel shaft through a bearing; welding wheels are matched with and fixedly connected to the periphery of the wheel body; a cooling plate is arranged between the wheel body and the welded plate and is sleeved on the wheel shaft; the end faces of the wheel body, the cooling plate and the welded plate are in contact with one another; at least three cooling passages which are coaxially arranged are arranged in the cooling plate; a radial entering passage and a discharging passage are formed in the cooling plate; and the two ends of each cooling passage are communicated with the entering passage and the discharging passage respectively. According to the arrangement, the welding machine can continuously work without intermittent outage, and the welding efficiency is increased; besides, the temperature rise of the welding wheels is reduced, so that sputtering during welding can be reduced, meanwhile the service life of the welding machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of welding machine manufacture, in particular to an improvement of a wheel electrode of the welding machine. Background technique [0002] The existing seam welding machine wheel electrode includes a wheel shaft, on which a coaxially arranged wheel body and a welding plate are arranged, a bearing is arranged between the welding plate and the main shaft, and the wheel body is fixed on the outer surface of the wheel shaft. The outer circumference of the wheel shaft is fixedly connected with the welding wheel, the welding plate is in contact with the end face of the wheel body, and the high temperature generated by the welding of the welding wheel is directly transmitted to the wheel shaft, the welding plate and other parts through the wheel body, so that the welding The temperature rise of the machine is increased. In addition, the higher temperature makes the welding need to be shut down intermittently for co...
