Profile cutting device

Abstract

A profile cutting device provided by the present invention includes a mounting base and a lifting shaft rotatably arranged on the mounting base. A cutting mechanism is provided on the top of the lifting shaft, and the cutting mechanism includes a first blade mounting frame and a lifting shaft set The second blade mounting frame, the first blade mounting frame and the second blade mounting frame are provided with a plurality of cutting blades, and the cutting blades are arranged in the first blade mounting frame and the second blade mounting frame through a telescopic mechanism , different processing forms can be adjusted between the first blade mounting frame and the second blade mounting frame. When the profile needs to be cut from the outside, only the cutting blade in the second blade mounting frame is required to cut the profile. When cutting outward from the inside of the profile, the first blade mounting frame and the second blade mounting frame extend outward after entering into the profile, and cut the profile from the inside to the outside. Multiple cutting blades can increase the contact area between the blade and the profile to avoid stress concentration.

Description

technical field [0001] The invention relates to the field of profile processing, in particular to a profile cutting device. Background technique [0002] Profiles are widely used in the field of construction and mechanical structures. The construction speed of profiles is fast, the floor space is small, and it is suitable for all-weather construction, which is less affected by climate conditions. The construction speed of the steel profile is about 2-3 times of the construction speed of the concrete structure, the capital turnover rate is doubled, and the financial cost is reduced, thereby saving investment. [0003] In actual use, the profile needs secondary processing such as cutting. Due to the special structure of the profile, there is an empty groove on the profile, so that there is no support device inside the profile at some positions, and no internal support can be obtained. When cutting, because the diameter of the existing cutting blade is too large, the contact a...

[0003] In actual use, the profile needs secondary processing such as cutting. Due to the special structure of the profile, there is an empty groove on the profile, so that there is no support device inside the profile at some positions, and no internal support can be obtained. When cutting, because the diameter of the existing cutting blade is too large, the contact area between the blade and the profile is small, and the stress is too concentrated, which will cause the profile to be deformed to varying degrees. The profiles in the prior art are all cut from the outside to the inside. The area with the largest deformation is located inside the profile, which is difficult to polish and grind, which reduces the mechanical properties of the profile and adversely affects the quality of the building or the mechanical structure
