Description

TECHNICAL FIELD

[0001] The utility model belongs to section bar cutting technical field especially relates to a cutting device for cutting of special-shaped section bar. BACKGROUND

[0002] As a basic and important technology in the field of modern industry, the development background and technological innovation of section bar cutting plays an important role in the quality and efficiency improvement of the entire manufacturing industry. In the process of accurate cutting of section bars, various technologies have emerged. In the period when the industrial level was relatively backward, manual cutting was the main way in the field of section bar cutting, which had the advantages of flexibility and convenience, and was suitable for cutting of different specifications of section bars. However, manual cutting also had significant disadvantages, such as poor cutting quality and obvious size deviation. With the development of technology, semi-automatic mechanical cutting emerged as the times require, which improved the problem of low efficiency of manual cutting, but the problem of single cutting section bar specification and limited cutting angle still existed.

[0003] A Chinese invention patent with patent announcement number CN118080955A and announcement date of May 28, 2024 discloses a multi-angle cutting device for aluminum profile processing, which comprises a workbench with an adjusting part. The adjusting part is composed of a vertical adjusting position with a cutting machine and a horizontal adjusting position with a clamping piece. The clamping piece includes symmetrically arranged bottom blocks, and an upper pressing block installed on the upper end of the bottom block through an electric push rod. The number of electric push rods on the bottom block is two and symmetrically arranged.

[0004] The general use method and advantages of the multi-angle cutting device for aluminum profile processing in the Chinese invention patent are as follows: the aluminum profile is conveyed between the bottom block and the upper pressing block with the upper end of the bottom block, and after single distance conveying of the aluminum profile is completed, the conveying equipment is paused. The upper pressing block is driven downward by the electric push rod until it cooperates with the bottom block to clamp and fix the aluminum profile, so as to avoid deviation of the aluminum profile during cutting. When the cutting surface of the aluminum profile needs to be shaped into a vertical state with the upper and lower ends on the same vertical plane, the cutting wheel of the cutting machine is always vertical. According to the cutting requirements, the position state of the cutting machine is adjusted through the horizontal adjusting position, so as to adjust the horizontal included angle between the cutting surface of the aluminum profile and the cutting wheel, and realize the formation of the multi-angle inclined cutting surface on the horizontal plane. When the cutting surface of the aluminum profile needs to be shaped into an inclined state with the upper and lower ends on different vertical planes, the bottom plate is in the original state, i.e. the bottom plate is perpendicular to the workbench. According to the cutting requirements, the position state of the cutting machine is adjusted through the vertical adjusting position, so as to adjust the vertical included angle between the cutting surface of the aluminum profile and the cutting wheel, and realize the formation of the multi-angle inclined cutting surface on the vertical plane. The advantage is that the use diversity of the cutting device as a whole is increased, and the application range of the cutting device as a whole is expanded.

[0005] However, the cutting device has at least the following disadvantages in actual use, in other words, the technical problems to be solved by the utility model: the overall structure of the cutting device is relatively complex, the use and maintenance cost is relatively high, and the cutting device can only cut the cross section of the profile and cannot be applied to other types.

[0006] Therefore, as described above, there is an urgent need for a cutting device that can be applied to various profiles and has a simple structure and convenient operation to solve such problems. Utility model content
