Cutting stress display device of full automatic inside diameter slicer with elastic feeding

Abstract

The invention relates to a cutting stress display device of a full automatic inside diameter slicer with elastic feeding, belonging to the field of mechanical processing. The device comprises a cutter driven by a spindle motor and an elastic feeding device, wherein the elastic feeding device comprises an X axis mobile worktable driven by a stepping motor and a Y axis mobile worktable driven by a stepping motor; and the X axis mobile worktable is arranged above the Y axis mobile worktable. A connection device for controlling and transmitting the displacement and forces between the X axis mobile worktable and the Y axis mobile worktable is internally provided with a member with elastic function or an assembly with elastic function. The cutting stress display device is characterized in that a display device is arranged on the elastic feeding device, the display device comprises a measuring device and an indicating device; the display device is used for displaying the stress deformation amount of an elastic element, and the deformation amount can be used for indicating the stress working state of a cutting blade so as to determine and adjust cutting feeding parameters and overcome the influence of corresponding equipment, control modes and cutting parameters on different machinable materials, thereby avoiding accidents of blade and material damage caused by over large stress of the blade.

Description

Technical field: [0001] The invention belongs to a device of an automatic inner circle slicer, and in particular relates to a cutting force display device for an elastic feed automatic inner circle slicer. Background technique: [0002] The inner circle slicer is the most commonly used processing equipment in the plane cutting of sintered NdFeB rare earth permanent magnet materials. It includes semi-automatic inner circle slicer, automatic inner circle slicer, automatic inner circle slicer includes microcomputer control system, cutting tool driven by main motor, X-axis moving table driven by stepper motor, stepper motor The Y-axis moving table is driven, the X-axis moving table is set above the Y-axis moving table, and the stepping motor driving the X-axis moving table is set on the X-axis moving table. [0003] In the traditional manual control cutting process, the position of the cutting surface in the Y-axis direction is first displaced and positioned. After positioning, the h...

Problems solved by technology

[0016] The stepper motor is rigidly connected and the working mode is rigid force. The step amount of each step is applied to the cutting edge of the incision slicer. In practice, there are the following shortcomings: when the stepping feed speed is set relatively low, both The working conditions are basically similar. Under such working conditions, the cutting speed (cutting area per unit time) is relatively low, which is 15-30% lower than the manual cutting speed on average; The number of machines is large, and all parameters are taken in a relatively safe and conservative range. Compared with manual sectioning, its cutting speed is about 20% lower

When the force on the knife edge is too large, the cut product will be severely concave and scrapped, and the knife will be burned and the material will be destroyed if it is serious.
