Description

Technical Field

[0001] The present invention relates to the technical field of special equipment for blade passivation, and particularly to a tool passivation machine. Background Art

[0002] With the in-depth study of the damage situation of CNC blades during the machining process, we found that the microscopic state of the blade cutting edge and the roughness of the blade surface (especially the rake face) have a great impact on the service life of the blade. This requires better blade edge passivation technology and blade polishing technology.

[0003] After grinding, there are generally microscopic notches (i.e., small chipping and saw cuts) of varying degrees on the tool edge. During cutting, the microscopic notches on the edge are extremely easy to expand, accelerating tool wear and damage. Modern high-speed cutting machining puts forward higher requirements for tool performance and stability. Generally speaking, after passivating the tool edge before coating, the strength of the tool edge and the firmness of the coating can be improved, thereby increasing the tool life. Especially in the machining of steel parts and intermittent cutting conditions, it is necessary to ensure that the tool edge has a certain strength, and at this time, the blade edge must be passivated.

[0004] The polishing of the blade surface has an obvious impact on the service life of the blade. The lower the surface roughness of the blade, the lower the friction between the chip and the tool body, the smaller the cutting resistance, and the lower the blade heat generation, thereby extending the service life of the blade.

[0005] In the prior art, most often the tool shank is inserted upside down into the rotating disk, and then the tool edge is inserted into the abrasive for rotary grinding through mechanical control. There are also some manufacturers that use a brush made of nylon wire (about 1 mm in diameter) containing abrasives (fine powders made of superhard materials such as diamond and silicon carbide) to brush the blade surface and edge, and under the action of the abrasives, a flexible grinding effect is generated on the blade edge, so as to meet the passivation requirements. The above technical means have many technical problems:

[0006] 1. It cannot adapt to the work of different types of tools. Whether it is rotary grinding in the abrasive or using a brush or other grinding parts for grinding, it cannot handle the grinding work of different types of tools. When designing these passivation machines, manufacturers often only consider the passivation of one or several common tools, and the passivation effect on some special tools is not good.

[0007] 2. The passivation efficiency is low. For the common abrasive passivation machines on the market, their efficiency is often only 300 - 400 pieces per hour. If the grinding quantity needs to be increased, new equipment, machines, workplaces, etc. need to be added, and the cost is too high.

[0008] 3. Uneven wear of the brush. For some common brush passivation machines on the market, the brushes are often in a fixed state. The blade clamping station shaft in the tool passivation machine passes under the brush through a circular production line, which results in light wear on both sides of the brush and severe wear in the middle, with uneven wear. If a straight-line production process is adopted, it will occupy too much space, and replacement, workpiece taking, etc. will become more troublesome. Summary of the Invention

[0113] In this embodiment, 28 station shafts 103 are provided on the turntable 102. One blade can be loaded at the top of each station shaft 103.

The rotation speed of the turntable 102 is 2 revolutions per minute (frequency conversion adjustable). The rotation speed of the station shaft 103 is set to 1600 rpm (frequency conversion adjustable). The working efficiency of this embodiment is not less than 1000 pieces per hour.

[0114] Due to the application of the above technical solution, compared with the prior art, it has the following advantages:

[0115] 1. The design of this equipment uses three brushes. The abrasive grain sizes used in the nylon filaments of the three brushes are different, so as to achieve different purposes: using a brush with coarser grain size can achieve the grinding effect, and using a brush with finer grain size can achieve the effect of fine polishing. Therefore, the passivation and polishing of the blade can be completed in one working cycle.

[0116] 2. The purpose of using a drum-type brush in this equipment is to improve work efficiency. The maximum rotation speed of the drum can reach 2000 revolutions per minute. Under the action of centrifugal force, the nylon filaments can become very stiff, thus improving the brushing efficiency.

[0117] 3. The movement of the blade in this equipment is a planetary movement, rotating while revolving. The main purpose is to reduce the floor area of the equipment. Since the three drum-type brushes are equivalent to three rotating cylinders, and their axes are parallel to the blade rotation plane, in order to improve the brushing efficiency and quality, the revolution trajectory of the blade does not adopt a circular trajectory, but a variable orbit mechanism is designed: when the blade revolves to the lower part of the brush, it moves in a straight line parallel to the axis of the brush.

[0118] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
