Abstract

The invention discloses a door and window corner setting system knife adjuster. The knife adjuster comprises a butterfly-shaped main ruler, an outer corner auxiliary ruler, an inner corner auxiliary ruler and pricking knife positioning baffles, wherein the butterfly-shaped main ruler is composed of a main ruler body, a left wing ruler and a right wing ruler, each of the front surface and the backsurface of the main ruler body is provided with limiting sliding grooves, the outer corner auxiliary ruler and the inner corner auxiliary ruler can be placed in the limiting sliding grooves correspondingly, the outer corner auxiliary ruler is a straight ruler with a triangular vertex angle at the top end and a triangular notch at the bottom end, the inner corner auxiliary ruler is a straight rulerwith triangular notches at the two ends correspondingly, the pricking knife positioning baffles are two L-shaped baffle devices which are symmetrical left and right, pricking knife end limiting plates are arranged at the upper ends of the pricking knife positioning baffles correspondingly, and the pricking knife positioning baffles are arranged on the left wing ruler and the right wing ruler of the butterfly-shaped main ruler in a sliding manner. According to the knife adjuster, a pricking knife system can be rapidly and accurately adjusted and positioned when set corners of the door and window are made, the door and window set corner quality is effectively improved, and the reject ratio is reduced.

Description

technical field

[0001] The invention relates to the technical field of processing and manufacturing aluminum alloy broken bridge doors and windows, in particular to an adjustment and positioning tool for a corner knife system of a corner assembly unit in door and window production, that is, a knife adjuster for a door and window assembly corner system. Background technique

[0002] In the process of door and window processing, it is an indispensable key link to use the corner forming machine to mechanically assemble the corners. Before the corners are assembled, the outer corner, inner corner, left knife and right knife of the corner machine must be adjusted respectively. Positioning, and then the knife system composed of the above four parts works at the same time to complete a set of corners. During this period, there is only one chance to tie the knife down, and the position of the lower tie is required to be correct and the depth is appropriate, so as to ensure that the s...
