4. The extrusion aluminum product angle sign indicating number section bar that appears in recent two years in addition, saw cut the back according to specification and dimension, the injecting glue angle sign indicating number of direct milling flutes, though solve above angle sign indicating number defect, still have fatal weak point, be exactly that the vertical face of angle sign indicating number is the cavity of fretwork, the size of cutting the angle sign indicating number is less than the cavity size and exceeds 0.2 millimeter, just causes serious hourglass to glue the condition very easily, causes the door and window cost to increase.

The movable corner brace and the glue injection corner brace which are commonly used on the market have the following defects and disadvantages:

(1) current door and window injecting glue angle sign indicating number: the A-die-cast corner brace has the problems that the processing speed is low, the mass production cannot be realized, the processing cost is high, the strength of the B-split combined movable corner brace corner is too low, the appearance of a door and window profile is affected by too many holes, and the water leakage problem cannot be solved. C-some angle sign indicating number is also utility model the injecting glue function, but structural design is unreasonable, very expense is glued to the angle intensity is also very low, take a lot of work and time expense glue to increase the cost of manufacture, D-especially some angle sign indicating number are with eccentric shaft connection mode, there is the potential safety hazard of structure, the eccentric shaft is very smooth very easily drops, and the rotation direction of eccentric shaft is not good the accuse during the equipment, it is taut clockwise in some circumstances, it is taut anticlockwise in some circumstances, the operation workman can't accomplish connection work fast.

The function that the die-casting angle sign indicating number also can't accomplish high-speed joint, it is most important that the production efficiency of die-casting angle sign indicating number is low, and is with high costs, die-casting angle sign indicating number still spends glue very much, because the injecting glue hole and the injecting glue runner of die-casting angle sign indicating number design are inside the angle sign indicating number, make most glue all pour inside the angle sign indicating number, do not use the position that should inject glue, it is split type still to have die-casting angle sign indicating number design, make the centre crack of separating in the angle sign indicating number when the pin is squeezed into, glue all flows into the angle sign indicating number cavity, cause a large amount of expense glues, it reaches about 30% to increase door and window cost of manufacture to increase, cause door and window manufacturing enterprise's manufacturing cost.

(3) Injection molding of corner connectors: the main shortcoming is that the self intensity of moulding plastics angle sign indicating number is low, and the material belongs to soft, can't reach the required intensity of door and window, leads to seriously spending the glue owing to design defect moreover, and a lot of glues all wastes uselessly, and the cost of manufacture has increased about 15%, and its door and window bight intensity performance is very poor, has serious potential safety hazard.

(4) Extruded aluminum saw cut groove corner connectors are just available in the market for these years: the main defects are that a trapezoidal diversion trench is milled, glue flows unsmoothly, the glue easily leaks into a corner brace cavity laterally to cause serious glue leakage, the other defect is that the glue injection position of the intersection point of two support arms of a corner brace is designed to be flat, the glue flow rate is very low, the glue injection easily causes glue on one side, the other side is glue-free, in addition, the defect of quick connection of an eccentric shaft used by the device is very large, two holes along with the circular shape are punched on the two support arms of the corner brace, labor is very high, the requirements on the size and the position precision of the corresponding hole on the frame are very high, and the function cannot be used by slight error in operation. The eccentric shaft still has the structure potential safety hazard, because the eccentric shaft design very smooth, does not have any vertical locking device, the eccentric shaft very easily slides and drops, causes the door and window frame fan to disintegrate to the rotation direction of eccentric shaft is difficult to handle during the equipment, and is taut clockwise sometimes, and is taut anticlockwise sometimes, and the operation workman can't accomplish connection work fast. And the angle brace is subjected to sand blasting treatment, so that an oxide layer of the aluminum angle brace is damaged, the corrosion resistance of the aluminum angle brace is very poor, and the safety is greatly reduced.
