Description

Technical Field

[0001] The present invention relates to the technical field of turning processing devices, and in particular to an integrated chip breaking device. Background Art

[0002] When turning plastic and difficult-to-machine materials, long strips of chips are easily formed and difficult to break, which can easily cause a large amount of chips to accumulate and entangle on the tool. The chips entangled on the tool not only affect the surface finish of the machined surface and interfere with the continuous machining process, but also affect the heat dissipation of the cutting, causing the temperature of the cutting area to rise, resulting in heat deformation of the machined surface of the workpiece, affecting the surface accuracy and machining quality of the workpiece.

[0003] The existing chip breaking device has the following defects:

[0004] (1) When using low-temperature cold air cutting, the broken chips are easily retained in the processing area, requiring additional chip cleaning devices, which increases the equipment size, complexity and operation difficulty;

[0005] (2) Lack of auxiliary chip removal design. When continuously turning plastic materials, unbroken chips are easily entangled with the rotating surface of the workpiece, causing scratches on the machined surface and abnormal wear of the tool;

[0006] (3) Its chip breaking mainly relies on the fixed chip breaker structure on the tool, which is difficult to meet the chip breaking needs in situations where the cutting amount and workpiece material change frequently. Summary of the Invention
