Description

[0001] The invention relates to the technical field of cutting sawing machines, and in particular to an automatic cutting sawing machine for aluminum door and window corner codes and a cutting method. Background Art

[0002] Aluminum alloy door and window angle brackets are parts used to connect the two long sides of the door and window frames and the upper and lower horizontal frames. These angle brackets are usually made of metal materials with certain strength and durability. Their function is to enhance the overall structural strength of the doors and windows and ensure that the doors and windows are not easily damaged during use. During the production process, a cutting saw machine is required to cut the long profiles into the required width.

[0003] The current cutting sawing machine uses a pneumatic system to control the advance and retreat of the saw blade and automatic feeding. The profile being cut is fixed by a fixed clamp, and the profile is pushed by a movable clamp to realize automatic cutting of the diagonal code and loading and unloading. However, a large amount of cutting debris will be generated in the cutting process, which will pollute the processing environment. The debris is scattered between the profile and the clamp, which will cause the clamping accuracy of the profile to decrease. At the same time, the fixed clamp and the movable clamp clamp different positions of the profile during feeding. The profile is relatively long. During the alternating clamping process, the profile will deviate to a certain extent, which will also reduce the cutting accuracy. Therefore, we propose an automatic cutting sawing machine and cutting method for aluminum door and window corner codes, which can reduce the debris and the reduction of the clamping accuracy of the profile caused by alternating clamping, and ensure the cutting accuracy.

Place the profile between the clamping plate and the limiting plate, make the push block contact the end of the profile, and drive the push block to move the profile forward to the required distance for cutting. The clamping plate presses the profile against the surface of the limiting plate to limit its position. S2, the saw blade moves toward the profile and cuts the profile.

[0012] 2. In the present invention, the clamping plate can be used to limit the position of the profile during cutting. When the profile moves, the clamping plate is away from the profile, and the pushing frame drives the pushing block to push the profile to move. During this process, the limiting roller and the pressure plate limit the profile to avoid the movement of the profile when the clamping plate is away from the profile, thereby ensuring the accuracy of the profile cutting.

[0013] 3.

The automatic cutting sawing machine for aluminum door and window corners according to claim 7, characterized in that: The protective cover (3) is provided with an inlet and an outlet for the profile to pass through, and a plurality of wind shields (5) are rotatably connected to the inlet and the outlet.

9. The automatic cutting sawing machine for aluminum door and window corners according to claim 8, characterized in that: It also includes a spraying mechanism, which is used to spray cutting fluid to the cutting position, and the spraying mechanism includes: A spray pipe (601), wherein a plurality of the spray pipes (601) are provided, wherein the spray pipes (601) are connected to a water inlet pipe (602), and wherein the spray pipes (601) are located inside the protective cover (3).

10. An automatic cutting method for aluminum door and window corners, using the automatic cutting sawing machine for aluminum door and window corners according to claim 9, characterized in that: The following steps are involved: S1. The profile is placed between the clamping plate (101) and the limiting plate (201), so that the push block (207) contacts the end of the profile, and the push frame drives the push block (207) to move, so that the profile moves forward a required distance for cutting, and the clamping plate (101) presses the profile against the surface of the limiting plate (201) to limit its position; S2, the saw blade (2) moves toward the profile to cut the profile, and after cutting, the clamping plate (101) moves away from the profile, and the push frame drives the push block (207) to continue to push the profile to move a specific distance, so as to push the cut corner code forward; S3, the protective cover (3) blocks the cutting debris, the cleaning plate (401) drives the brush (402) to rotate, and cleans the surface of the clamping plate (101) and the profile, and at the same time the fan (501) sends air to the inside of the blowing pipe (502), and the nozzle (503) rotates with the cleaning plate (401) to blow away the debris; S4. The spray pipe (601) sprays cutting fluid into the interior of the protective cover (3) to cool and lubricate the cutting position, while flushing the debris into the interior of the debris collection box (4), and the liquid absorbs the debris.
