Description

Technical Field

[0001] The invention relates to the field of aluminum material cutting, and in particular to an automatic short side cutting device for aluminum profiles. Background Art

[0002] At a time when the intelligent manufacturing equipment industry is booming, various industries have increasingly higher requirements for production efficiency, processing accuracy and degree of automation. Aluminum profiles, with their many excellent properties such as light weight, high strength and corrosion resistance, have been widely used in many fields such as construction, transportation, electronics, etc.; with the continuous expansion of the application scenarios of aluminum profiles, the requirements for their processing accuracy and efficiency have become more and more stringent. In the processing of aluminum profiles, cutting is an extremely critical link, especially short-side cutting. Its processing quality is directly related to the assembly accuracy and overall performance of subsequent products. The traditional short-side cutting method of aluminum profiles mostly relies on manual operation. The operator needs to hold the cutting tool and cut the aluminum profile based on his own experience and skills. In order to facilitate the cutting of aluminum profiles, a cutting device is needed.

[0003] In the intelligent manufacturing equipment industry, aluminum profiles are usually cut by sawing in aluminum profile processing scenarios. However, in the cutting positioning link, the aluminum profile is mainly fixed by manual hand-held tightening, and the operator's limbs need to be close to the high-speed saw blade. When the aluminum profile accidentally slides during the cutting process or the operator makes an error in operation, it is very easy to cause a cutting injury accident. At the same time, the tool groove structure design of existing sawing equipment has limitations. Most of them are fixed and cannot be dynamically adjusted according to actual working conditions such as saw blade specifications and cutting angles. When beveling operations are performed, the saw blade and the fixed tool groove are in an inclined state, and the actual retraction space is compressed, resulting in the saw blade frequently coming into hard contact with the inner wall of the tool groove during the return process. This not only accelerates the wear of the saw blade, but may also cause serious consequences such as saw blade cracking and equipment failure, affecting production continuity and processing accuracy.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The displacement bottom blocks of the two sets of top parts are slidably connected to the outer beam frame. Through the cooperation of the positioning socket and the cylindrical rod on the top of the beam clamp, the top part can be quickly positioned and fixed on the bottom mounting part, ensuring that the aluminum profile can be firmly clamped during the cutting process. The shrinkage support plate slides in the displacement groove and can be adaptively adjusted according to the size of the aluminum profile to enhance the stability of the clamping. The displacement block of the auxiliary top can slide on the top of the displacement bottom block, and the position can be accurately adjusted by the displacement screw. After the aluminum profile is initially clamped, the flip block is driven to flip by the toggle rod, and the flip clamp is driven to contact the aluminum profile at the same time, so that the flip clamp clamps the area close to the cutting position, so that the aluminum profile is fully clamped under the action of the flip clamp and the auxiliary clamp.

[0016] 2. The top support frame in the adjustment part can rotate around the top of the bottom mounting plate, and the rotation angle can be accurately quantified through the metering disk. At the same time, the tilting frame of the flipping part can be driven by the positioning rod to adjust the angle through the docking screw hole, thereby driving the flip guard and the cutting disc of the cutting part to change the angle. This multi-dimensional angle adjustment method can meet the needs of short-side cutting of aluminum profiles with various complex angles. The torsion block is connected to the cutting part through a synchronous plug rod.
