Description

CUTTING MACHINE FOR ALUMINIUM SASH FRAME

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aluminum chassis processing apparatus for processing holes or grooves in a profile such as an aluminum chassis, and in particular, a processing apparatus capable of processing holes or grooves on the upper and lower sides of the chassis by one press operation in one apparatus. It is about.

Recently, the window frame is generally used as an aluminum chassis having excellent corrosion resistance and sound insulation. The aluminum chassis forms a window frame together with the upper and lower horizontal frames and the left and right vertical frames which are assembled and moved on the rails of the window frame.

In order to assemble and fix the horizontal frame and the vertical frame, the factory manufactured aluminum chassis must be cut to fit the size of the window and processed in several stages. As shown in FIG. 1, the outer partition 11 of the aluminum frame requires a through hole 13 for a driver through hole, a roller adjusting hole, etc., and the inner partition 12 has a through hole for a screw assembly hole, a roller assembly hole, and the like. 14, the outer bulkhead 11 and the inner bulkhead 12 grooves 15, 16 should be machined to fasten the horizontal frame, and the horizontal frame fitting groove 17 on the outer bulkhead 11 is required. Should be formed. To this end, the aluminum chassis for assembly is completed only after the two-step and six-step processes are alternated between the outer partition 11 and the inner partition 12.

A simple designed aluminum chassis processing device has a disadvantage of low productivity because it is cheap but is processed through several steps, and a processing device having a low processing step has a high productivity but a high price. In addition, in the case of a device having a low processing step, there are problems in durability, such as a large number of parts of the device and a complicated operation mechanism, such as frequent occurrence of failure, and it is difficult to use a general press device because the height of the device is large.

Therefore, the present invention has been made to solve the problems of the prior art as described above, the present invention can simultaneously process the through-holes and grooves and frame fitting grooves of the inner and outer partitions of the aluminum chassis in one press working operation, It is an object of the present invention to provide a processing device that is simple to operate, has a small fixation, a durability, and a small size of the operating device, which is suitable for use in a general press device.
