High-performance online cutting-off device

Abstract

The invention discloses a high-performance online cutting-off device, which comprises an X-directional motion platform and an X-directional linear motor, a Y-directional motion platform and a Y-directional linear motor, a Z-directional motion bracket and a Z-directional linear motor, as well as an X-directional grating, a Y-directional grating and a Z-directional grating; wherein the Y-directional motion platform is provided with a cutting-off tool assembly, the cutting-off tool assembly comprises a cutting-off tool fixed die, a cutting-off moving die, a cutting-off tool moving die guide sleeve and a cutting-off tool bracket, and the cutting-off tool moving die is connected with the Z-directional linear motor through a coupling mechanism; the X-directional grating, the Y-directional grating and the Z-directional grating are respectively used for measuring the speeds and the displacements of the X-directional moving platform, the Y-directional moving platform and the Z-directional liner motor; and the feeding end of a section bar to be cut off is provided with a speed measurement device, the section bar is pasted with a bar code and the bar code contains the displacement length information of the section bar. The invention has high cutting-off precision and production efficiency, and can be applicable to the cutting of the section bars with various shapes and realize the onlinecutting-off without stalling the section bars during cutting off.

Description

technical field [0001] The invention relates to a cutting device for cold-formed profiles, in particular to a high-performance online cutting device. Background technique [0002] Cold-formed profiles are more and more widely used in construction, auto parts, power transmission facilities and other fields. Due to the low cutting accuracy of the cutting device for cold-formed profiles in the prior art, secondary cutting is still required after the cold-formed profiles are cut to length. , which results in a waste of surplus material. Because the batch size is large (the annual output is often hundreds of thousands), so the waste is huge, and because the cutting frequency is not high, the productivity is not high, and the prior art is generally difficult to achieve more than two cuts per second. [0003] In addition, existing equipment can only cut profiles of a fixed shape (such as straight profiles, curved profiles, and irregular profiles), and it is difficult to adapt to c...

[0002] Cold-formed profiles are more and more widely used in construction, auto parts, power transmission facilities and other fields. Due to the low cutting accuracy of the cutting device for cold-formed profiles in the prior art, secondary cutting is still required after the cold-formed profiles are cut to length. , which results in a waste of surplus material

Due to the large batch (the annual output is often hundreds of thousands), the waste is huge, and because the cutting frequency is not high, the productivity is not high. It is generally difficult to cut more than twice per second in the prior art.

[0003] In addition, existing equipment can only cut profiles of a fixed shape (such as straight profiles, arc profiles, and irregular profiles), and it is difficult to adapt to cutting profiles of various shapes at the same time.
