Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a profile cutting equipment. Background Art

[0002] During the production of doors and windows, aluminum profiles need to be cut at 45-degree angles at both ends so that adjacent aluminum profiles can be spliced ​​at 90-degree angles. Currently, the production process of most cutting machines and double-head saw cutting machines on the market is to first measure the length of the profile to be cut and then move the two moving cutting heads to the position where the saw needs to be cut. After the profile is fixed, cutting is carried out;

[0003] Reference application number: CN201710568985.1 is a 45° double-head cutting machine. The existing two movable cutting head structures include two chassis, a cutting assembly and a pulley in the chassis, wherein the chassis includes a plurality of metal plates, which are fixedly connected by screws to form a box structure, the top of which is a working surface for profile cutting, and the pulley is used for linear sliding on the slide rail. The structure of the chassis of such a cutting machine is too loose and the stability is insufficient; at the same time, the fixation of the profile now relies on the cylinder installed on the working surface to press the profile on the working surface to fix the profile, but the state of the profile before cutting is a continuous long strip, and its size is much longer than the total length of the cutting machine. Therefore, when loading, it is necessary to manually lift one end of the profile and pull it to the first movable On the cutting head, after the first movable cutting head fixes one end of the profile, the second movable cutting head is controlled to gradually move away from the first movable cutting head along the slide rail, and stops after moving to the length to be cut. However, the profile is now on the two movable cutting heads and is in a fixed state. During the movement of the second movable cutting head, the working surface of the second movable cutting head and the surface of the profile will rub against each other and get stuck, which may easily scratch and damage the surface of the profile. Moreover, the long strip of profile is always in a suspended state during the cutting process. Although current manufacturers will place a shelf at the rear end of the cutting machine to support the profile, there is still a distance between the shelf and the movable cutting head that cannot be supported. Under the action of its own weight pressure, the profile is easily bent and deformed, which seriously affects the quality of the profile. Utility Model Content
