Description

Cutter passivation machine

Technical Field

The invention relates to the technical field of special equipment for blade passivation, in particular to a cutter passivation machine.

Background

With the intensive research on the damage condition of the numerical control insert in the machining process, the microscopic state of the cutting edge of the insert and the roughness of the surface (especially the front face) of the insert are found to have great influence on the service life of the insert. This requires a better blade edge passivation process and a better blade polishing process.

The edge of the sharpened cutter generally has microscopic gaps (namely, micro tipping and saw cut) with different degrees. The microcosmic gap of the cutting edge is extremely easy to expand in the cutting process, and the abrasion and the damage of the cutter are accelerated. Modern high speed machining places higher demands on tool performance and stability, and generally after the tool edge is passivated before coating, the strength of the tool edge and the firmness of the coating can be improved, thereby prolonging the service life of the tool. Particularly, under the working conditions of processing steel parts and interrupted cutting, the cutting edge of the cutter is ensured to have certain strength, and then the cutting edge of the blade needs to be passivated.

The effect of the polishing of the insert surface on the useful life of the insert is evident, the lower the roughness of the insert surface, the lower the friction between the chip and the cutter body, the lower the cutting resistance, and the lower the heat generation of the insert, thereby extending the useful life of the insert.

In the prior art, a cutter handle is mostly inserted in a rotating disk in an inverted mode, then a cutter edge is inserted into a frosted surface through mechanical control to rotate and grind, some manufacturers also use nylon wires (with the diameter of about 1 mm) containing grinding materials (micro powder made of superhard materials such as diamond, silicon carbide and the like) to manufacture a hairbrush, the surface and the cutting edge of the blade are brushed, and the cutting edge of the blade is flexibly ground under the action of the grinding materials, so that the passivation requirement is met, and the technical means have a plurality of technical problems:

1. it is not suitable for the work of different cutters. No matter the cutter is ground in a grinding sand in a rotating mode or by grinding pieces such as brushes and the like, the cutter grinding machine cannot deal with different cutter grinding operations, and manufacturers often only consider the passivation of one or more common cutters when designing the passivation machines, so that the passivation effect of some special cutters is not good.

2. The passivation efficiency is low. The efficiency of the common sanding passivation machine in the market is only 300-.

3. Uneven wear of the brush. For some common brush passivation machines on the market, the brushes are always in a fixed and unchangeable state, and a blade clamping station shaft in the cutter passivation machine passes through the lower part of the brushes through a circular assembly line, so that the two sides of the brushes are slightly abraded, the middle part of the brushes is seriously abraded, and the abrasion is uneven. If the straight line flow process is adopted, too much space is occupied, and the replacement, the taking of the parts and the like become more troublesome.
