Section bar cutting saw

Abstract

The invention discloses a sectional material cutting saw, and mainly relates to the technical field of sectional material cutting. The cutting saw comprises a sawing machine and two cutting device assemblies; each cutting device assembly comprises a base frame, a workpiece pressing and positioning device, a cutting servo motor and an adjustable cutting module; the adjustable cutting module comprises a module frame, a cutting angle adjusting mechanism and a cutting saw advancing and retreating mechanism; the cutting angle adjusting mechanism comprises an angle adjusting servo oil cylinder, and a piston rod of the angle adjusting servo oil cylinder is controlled to stretch out and draw back to control the module frame to rotate and adjust along the hinge seat; and the cutting saw advancing and retreating mechanism comprises a feeding servo oil cylinder, and the cutting servo motor is controlled to rotate and adjust along a rotating shaft by controlling a piston rod of the feeding servo oil cylinder to stretch out and draw back. The cutting saw has the beneficial effects that: corner cutting at any angle within the range of 22.5-90 degrees can be completed; and scraps at the cutting edge of a cutting saw blade can be timely and conveniently cleaned, and the safety is greatly improved due to the fact that the retracting stroke is monitored in the cutting process.

Description

technical field [0001] The invention relates to the technical field of profile cutting, in particular to a profile cutting saw. Background technique [0002] The profile cutting saw is the main equipment for profile cutting at present. With the innovation of modern architectural design, there are many special-shaped buildings that require a wider angle for building base frame profiles. The current profile cutting section requirements are only limited to conventional angles. Cutting angles, such as 45°, 90°, 60°, etc. Two building base frame profiles with conventional angle cut angles are naturally combined into conventional corner angles (such as: two 45° angle cut profiles are 90°, and two 60° angle cut profiles are 120°). [0003] As attached in the manual Figure 11 As shown, at present, the requirements for the joint angle α of special-shaped architectural profiles are mostly in the range of 90°-150°, but the most special ones also require the joint angle α of architect...

Problems solved by technology

At present, there is no profile cutting machine that can achieve any angle within the above range

[0004] Moreover, the existing profile cutting equipment does not have a chip cleaning mechanism module to clean the cutting edge of the cutting saw blade. If cutting soft metal profiles, especially plastic profiles, if the debris on the cutting edge of the cutting saw blade is not cleaned in time, the cutting process will be repeated. The middle is easy to be squeezed and sticks to the cutting edge, which is more difficult to clean. Therefore, the debris on the cutting edge of the cutting saw blade needs to be cleaned in time to maintain the expensive cutting saw blade and improve its service life.

[0005] In addition, when adjusting the cutting angle of the cutting saw blade, it needs to be adjusted after the cutting saw blade retracts, because the cutting saw blade is in the cutting seam without retracting the blade, and the adjustment of the cutting angle angle of the cutting saw blade is blocked by the limit of the cutting seam , while the damage mechanism

At present, the program control is used to adjust the cutting angle of the cutting saw blade after retracting the knife first. However, in case of jamming during the retracting process or loose or disengaged threaded connections in the mechanical mechanism of the retracting blade, resulting in the inability to complete the retracting action, if Performing the adjustment of the cutting angle of the cutting saw blade will cause damage to the entire machine, greatly increase the maintenance cost, and may also affect the life safety of the machine tool operator
