Description

Technical Field

[0001] The invention relates to the technical field of processing and manufacturing aluminum alloy thermal break doors and windows, and in particular to an adjustment and positioning tool for a corner assembly knife system of a corner assembly machine in the manufacture of doors and windows, namely a knife adjuster for a corner assembly system of doors and windows. Background Art

[0002] In the process of processing and manufacturing doors and windows, the use of mechanical corner assembly machines is an indispensable key link. Before corner assembly, the outer top corner, inner top corner, left piercing knife and right piercing knife of the corner assembly machine must be adjusted and positioned respectively, and then the piercing knife system composed of the above four parts will work at the same time to complete a corner assembly. During this period, the piercing knife will only be used once, and the position of the piercing knife must be correct and the depth must be appropriate to ensure that the corner assembly is in place and firm. It can be said that the adjustment and positioning of the piercing knife system is related to the quality of corner assembly, and the quality of corner assembly is related to the strength of the corners of the door and window frames, which in turn affects the overall structural strength, service life, safety, sealing and other performance of the doors and windows. When different profiles are used, the position of the piercing knife system must be adjusted. The difficulty lies in that the adjustment and positioning of each part of the piercing knife system are independent, but their mutual positions are related. The adjustment of any position must be followed up by adjustments to other parts of the system, which is difficult to adjust and inefficient. In addition, there has been no special tool for adjusting and positioning the piercing system in the field of door and window manufacturing. Experienced technical workers can only estimate and judge the positioning of the piercing system and the piercing depth of the piercing knife, which is prone to deviations and produces unqualified products.
