Description

Automatic welding slag cleaning system for surface of metal composite pipe fitting Technical Field The invention relates to the technical field of welding, in particular to an automatic welding slag cleaning system for the surface of a metal composite pipe fitting. Background Under the condition of ensuring the performance of the metal pipe fittings in industry, in order to reduce the manufacturing cost, pipe fitting raw materials of different materials are adopted for butt welding so as to obtain a complete pipe fitting with coincident axes. For example, in the manufacture of air conditioner condensation pipelines, copper pipes with higher cost are only adopted at specific positions, aluminum pipes with lower cost are adopted at other positions, and the ports of the copper pipes and the aluminum pipes are welded together in a resistance welding mode in the processing process. The outer surface of the welded composite pipe fitting can remain annular welding slag, and the welding slag needs to be cleaned. The traditional manual cleaning mode is that an operator holds the composite pipe by one hand or presses the composite pipe on a workbench, and then the welding slag is gradually removed along the circumferential direction by using a hard cleaning tool, so that the welding slag is not thoroughly cleaned or the surface of the composite pipe is damaged easily due to improper force. In order to ensure the surface quality of the composite pipe, a common manufacturer is provided with an automatic welding slag removing device, namely, an external power source drives a cutter head to axially and once remove the annular welding slag area on the composite pipe. The tool bit is generally divided into an annular integrated tool bit and an arc split tool bit, and the split tool bit is widely adopted because of the advantages of being convenient for operation and maintenance. In the actual processing process, an operator needs to take the composite pipe from the material preparation area, press the composite pipe on the cutter head or the limiting piece, wait for the cutter head to translate axially to remove welding slag, take off the welding slag ring on the composite pipe after the cutter head is separated from the composite pipe, finally put the composite pipe into the finished product area, and repeat the process to remove the welding slag on the next composite pipe. In the process, the material taking and feeding processes are manually completed by operators, and the welding slag removing process of the cutter head also needs to be carried out by the operators to hold the composite pipe stably, so that the standby time of the cutter head is long, and the processing speed is seriously influenced during mass production. If the double mechanical arms are used for alternately clamping to take materials and feed materials, although the speed can be theoretically improved, the cost of design, manufacture and maintenance is higher, and the requirement on the operation space is also high due to the fact that the composite pipe has a certain length, so that the practicality is poor. Based on this, how to improve the existing welding slag removing equipment, the time required for the welding slag removing work of the single composite pipe is compressed, and the problem to be solved by the person skilled in the art.
