Description

Technical Field

[0001] The utility model relates to a full servo corner head for door and window profiles, belonging to the technical field of door and window processing. Background Art

[0002] Doors and windows are usually fixed by assembling frames with aluminum profiles around them. The profiles on the four sides need to be spliced and fixed to each other, and a 90-degree right angle is formed at the connection between each side. The pin is a common part for connecting the horizontal profile and the vertical profile of the door and window, which plays a very important role in the overall strength and firmness of the door and window. In addition to the connection method using pins, there is also a connection method of punching, riveting and extrusion in the prior art. The corner connector is provided with a corner assembling groove. Through two (or multiple) corresponding corner assembling knives on the corner assembling machine, the positions on the side walls of two aluminum profiles that are butted at a 90° angle and corresponding to the corner assembling groove on the corner connector are simultaneously punched and riveted, so that the profile wall at this position is punctured by the corner assembling knife, forming an inward "barb" shape with partial cutting and partial connection. The "barb" tightly squeezes into the corner assembling groove of the corner connector already installed in the inner cavity of the aluminum profile. Through the local deformation of the aluminum profile, the profile and the corner connector are fixed together, so as to achieve the purpose of tightly combining the 90° angle of the aluminum profile; after such extrusion is completed for the four corners of the frame formed by the four side frame profiles to form an aluminum door and window frame, the side frame profiles are connected into a whole frame structure through the corner connector.

[0003] It can be seen that the corner assembling machine is a key equipment for the production of aluminum doors and windows. The existing door and window punching, riveting and extrusion corner assembling machine has low processing efficiency. The patent with the application number 201410194517.9 discloses a new type of corner head, including a head bottom plate and a left support plate, a right support plate, an external positioning mechanism, an internal positioning mechanism, a left corner assembling mechanism, a right corner assembling mechanism and a vertical material pressing mechanism fixed on it. The left corner assembling mechanism and the right corner assembling mechanism have the same structure and are symmetrically arranged. The vertical material pressing mechanism is arranged on the external positioning mechanism, with low automation and low processing efficiency. Content of the Utility Model
