铝门窗单头组角机主要用于角码结构的平开门窗 45 °接缝的挤压联结。
组角前，在两个被联结的型材腔内放一公用角码，定位夹紧后，两个液压驱动的冲头强力冲向角码的凹槽处，使型材外壁产生永久性的冷变形。将两型材接缝挤压，使联结具有螺钉或其它联接方法所不具有的高强度、高效率、高精度。
The machine is mainly used for extrusion and connection of 45 ° seam casement window with angle joint structure.
Before operating, place a corner-brace in cavities of two profiles to be connected. After locating and clamping,the two hydraulic driven punching blocks punch towards the flute of corner-brace, making the outer wall of the profile permanently cold-deformed. Extrude the seam of two profiles and make strength, efficiency and precision of the connection higher than using any other means for connection.
