Description

Technical field:

[0001] The utility model relates to the technical field of profile sawing and cutting, in particular to an inner-swing angle double-head saw for aluminum profiles. Background technology:

[0002] Aluminum profiles are commonly used raw materials for doors, windows, curtain walls, sun rooms, etc. In order to meet design requirements, aluminum profiles need to be sawed, drilled, milled, and angled. The existing technology for sawing generally uses double-headed saws for processing. The working principle and structural layout of existing double-headed saws are relatively mature. For example, a double-headed saw for aluminum profile processing disclosed in a Chinese patent (authorization announcement number: CN211438373U), and a double-headed saw cutting machine with automatic positioning function disclosed in a Chinese patent (public announcement number: CN111360320A). The widespread use of double-headed saws has promoted the rapid development of the door and window industry.

[0003] With the further development of the door and window industry, especially the rise of the home decoration industry and system doors and windows, higher requirements are put forward for product quality, and corresponding sawing processing accuracy is also put forward for higher requirements. However, there are still some technical problems in the actual application of the existing double-headed saw, and the existence of these technical problems directly affects the sawing processing accuracy, which in turn leads to a decline in product quality. The specific technical problems are as follows. For example, the feed drive of the existing double-headed saw generally adopts cylinder drive. Because the gas is compressible, there will be unevenness in the sawing feeding process, especially when the saw blade just contacts the aluminum profile and when the saw blade just cuts the aluminum profile, there will be obvious unevenness, which will lead to low finish of the sawing surface and affect product quality. For another example, in order to meet the sawing requirements of 45°, 90° or other angles, the existing double-headed saw is usually designed as a swingable structure. After the swing is completed, it needs to be positioned. The existing technology generally adopts a swing cylinder for positioning, but in the actual application environment, the air pressure sometimes has a problem of poor stability (such as common air leakage), and once the air pressure changes, the swing angle will change, which will affect the sawing processing accuracy and ultimately affect the product quality. Therefore, it is necessary to optimize and improve the existing double-head saw in order to further improve the sawing accuracy.

[0036] Instructions for use of this application for aluminum profile inner swing double head saw:

[0037] In actual application, the workbench needs to be equipped with a profile positioning fixture and a control system. This part belongs to the existing technology (basically the same as the existing double-head saw), which can be directly purchased or customized. The aluminum profile inner swing angle double-head saw of this application is basically the same as the existing double-head saw, and the main difference lies in the difference in sawing feed and swing angle positioning. The following is an explanation of the differences:

[0038] (1) Swing angle positioning

[0039] When the swing angle needs to be adjusted, first start the inner positioning cylinder 608, and the inner positioning cylinder 608 moves to retract the inner positioning slider 607. At this time, there is no internal positioning. Then start the swing angle cylinder 5, and the swing angle cylinder 5 drives the swing angle frame 4 to rotate. When the swing angle is in place (detected by sensor 609), the front swing arm 601 contacts the outer positioning bolt 604 to position the outer swing angle, and the rear swing arm 701 contacts the rear positioning bolt 704 to position the outer swing angle. Then start the inner positioning cylinder 608 again, and the inner positioning cylinder 608 drives the inner positioning slider 607 to extend, and the inner positioning roller 605 on the front swing arm 601 acts on the side of the inner positioning slider 607 to position the inner swing angle, thereby realizing two-way swing angle positioning.

[0040] (2) Sawing feed

[0041] After the aluminum profile is positioned and clamped on the workbench 3, the servo motor 12 is started. The servo motor 12 drives the feed slide 10 to feed longitudinally through the feed gear 13 and the feed rack 9. While the feed slide 10 feeds longitudinally, it drives the sawing servo motor 15, the sawing spindle 14 and the saw blade 17 thereon to feed longitudinally. The sawing servo motor 15 drives the sawing spindle 14 to rotate through the belt drive 16. The rotation of the sawing spindle 14 drives the saw blade 17 thereon to rotate, thereby completing the sawing process of the aluminum profile.

[0042] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0043] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
