Welding machine and welding method for door and window whole window sealing strip

Abstract

The invention discloses a welding preparation method of a door and window whole window sealing strip. A welding machine comprises a bottom frame, a working table, an open type positioning die cavity,a PE coiled material supply device, an IR heating device (5), a cut-off device and a control system. The open type positioning die cavity is fixedly arranged on the working table; the PE coiled material supply device comprises a PE coiled material installation roller (7) and a PE coiled material device and is fixed below the working table; the IR heating device (5) and the cut-off device are located on the lower portion of the open type positioning die cavity and are fixedly arranged below the working table. The method comprises the preparation steps of die assembly, feeding and clamping, heating and welding, heat preservation and shaping, die opening, and discharging and inspection. Horizontal welding is adopted, welding waves are stable, the welding quality is good, and the problems thatvertical welding waves are prone to forming burrs, the quality stability of door and window sealing strip products is directly affected, redundant parts and burrs of connecting corners need to be trimmed, and the efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of butt joint processing of door and window sealing strips, in particular to a welding machine for sealing strips of doors and windows and a welding method thereof. Background technique [0002] Passive house refers to a low-energy house built by combining various passive energy-saving means such as natural ventilation, natural lighting, solar radiation, and heat from indoor non-heating sources with high-efficiency energy-saving technologies for building envelopes. This kind of building can significantly reduce the energy consumption of the building while significantly improving the comfort of the indoor environment, and minimize the dependence on active mechanical heating and cooling systems. With the popularization of the concept of energy saving, passive buildings have attracted more and more attention from the industry and the market under the due meaning of building energy conservation, green buildings ...

AI Technical Summary

Problems solved by technology

Usually a working cycle takes about 2-6 minutes, including the following steps: mold closing---feeding and clamping---heating and welding---heat preservation and setting---opening mold---discharging---repairing- - Inspection, there is a long welding time, after the material is discharged, it is necessary to manually cut off and trim the excess parts and burrs of the corners, which directly affects the quality and stability of the door and window sealing strip products. At the same time, the vertical frame fixed on the work surface and the PE coil are pulled The film-drawing cylinder and robot arm of the device make the work surface messy and inconvenient for processing and discharging
