Abstract

The invention discloses an aluminum profile continuous extrusion interrupting method and device capable of achieving automatic weld joint finding. The device at least comprises an extruder, a quenching device and a rail are arranged at the discharging end of the extruder in the extruding direction, a traction machine is slidably connected to the rail, an interrupting saw is fixedly connected to the traction machine, the traction machine is located on the discharging side of the quenching device, a rear finishing equipment PLC is fixedly and electrically connected to the traction machine, the traction machine is driven by the rear finishing equipment PLC to slide on the rail, an extruder PLC is fixedly and electrically connected to the non-operation side of the extruder, and the extruder PLC and the rear finishing equipment PLC are in electrical signal connection with each other. According to the device, precise interrupting of aluminum profile continuous extrusion at a weld joint is achieved, the production efficiency and the finished product rate of an extruded product are improved, full automation of extrusion production sawing interrupting is achieved, the interrupting length isautomatically read, conveyed and updated by the PLCs, manual intervention is not needed, and the production cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of material processing, in particular to a continuous extrusion interruption method and device for automatic welding of aluminum profiles. Background technique [0002] In the continuous extrusion production process of aluminum profiles, it is necessary to interrupt the sawing of the extruded aluminum profiles. There are two existing interruption methods. One is to manually realize the two continuously extruded aluminum ingots. The weld produced between the welds is then interrupted by sawing at the weld with a manual saw; the other is automatically or manually interrupted by a mobile hot saw, that is, before extrusion, through the extrusion ratio, the length of the aluminum ingot, and the remaining thickness Calculate the length of the profile extruded by an aluminum ingot, and then set the interruption length on the operation screen of the mobile hot saw, so that the mobile hot saw will automatically be interru...

AI Technical Summary

Problems solved by technology

[0002] In the continuous extrusion production process of aluminum profiles, it is necessary to cut and interrupt the extruded aluminum profiles. There are two existing interruption methods, one is to realize it manually, and to search for two continuously extruded aluminum ingots manually The weld seam produced between them is then cut and interrupted at the weld seam with a manual saw; the other is to automatically or manually interrupt by moving the hot saw, that is, before extrusion, through the extrusion ratio, the length of the aluminum ingot, and the thickness of the excess Calculate the length of a profile extruded from an aluminum ingot, and then set the interruption length on the operation screen of the mobile hot saw, so that the mobile hot saw will automatically interrupt according to the set length; however, because each aluminum There are certain differences in the length of the ingot and the diameter of the aluminum ingot, and the control of the excess thickness is not completely accurate. Generally, there is a tolerance of ±5 mm. Therefore, the actual length of the extruded aluminum profile is Different lengths, especially in the case of relatively large extrusion, the difference is greater, so it is difficult to saw each interruption near the weld, and there will be accumulated errors. In the production process, it is necessary to manually correct the interruption length to compensate
