Description

Technical field:

[0001] The utility model relates to the technical field of processing profile connectors, in particular to a bidirectional automatic chamfering and tapping integrated machine for stile angle brackets. Background technology:

[0002] Munt is a professional term in construction, mainly used in building doors and windows. It is a horizontal or vertical division used to distinguish between a frame and a spliced ​​frame. When the munt is connected to the frame, it is usually necessary to install a munt angle code to enhance the connection strength. The munt angle code is connected to the frame and the munt by screws. Figure 6 The figure shows a schematic diagram of the structure of the commonly used center stile angle code profile.

[0003] With the continuous development of the door and window industry, in order to facilitate the rapid installation of the muntin angle brackets, new design requirements have emerged, requiring threaded holes to be designed at both ends (i.e., in both directions) of the muntin angle brackets, so that there will be no positive and negative situations when installing the muntin angle brackets, and both ends are the same, thereby significantly improving the muntin installation efficiency. However, there is no mechanized equipment specifically for bidirectional chamfering and tapping in the existing muntin angle bracket processing equipment. For example, the muntin angle bracket automatic processing equipment previously applied by our company (authorization announcement number: CN 216462955 U), although it can realize the mechanized drilling, tapping and cutting processing of the muntin angle brackets, cannot realize efficient bidirectional chamfering and tapping processing, which undoubtedly restricts the processing efficiency of the muntin angle brackets.

[0041] The profile 11 is placed on the feeding unit 2.

The equipment of the present application only completes part of the process of the center stile angle code. Usually, the center stile angle code 12 also needs to be drilled and tapped at the bottom. These processes can be processed by other equipment.
