Abstract

The utility model relates to a high-precision dead smooth file which can overcome the defects of the conventional dead smooth file, prevent embedding of filings, improve the precision of a processed plane of a part remarkably, reduce the surface roughness of the plane greatly and increase efficiency and basically requires no filing removal. The high-precision dead smooth file is made of high speed steel bars (HSS). By using a processing method of electro-corrosion such as linear cutting, a high speed steel bar is cut into a sheet 3mm-4mm thick; a file handle part is machined, and thus a complete file is made. The high-precision dead smooth file has the following advantages: firstly a plane with the roughness value of Ra1.6 microns-Ra 0.8 microns can be formed through processing; secondly, during the processing of two planes perpendicular to each other, when one plane is processed, the other plane will not be scratched; thirdly, the straightness and planeness of two working planes formed by linear cutting can be limited to 0.01mm-0.02mm, so that the file can be used for processing high-precision planes with extremely high planeness requirements.

Description

The glossy file of a kind of high accuracy

Technical field

The utility model relates to the glossy file of a kind of high accuracy.

Background technology

File is one of conventional instrument of pincers worker, and glossy file is a kind of file for refine plane roughness.For a long time, in production and bakeoff, all use traditional glossy file to repair plane.Owing to having larger groove between traditional glossy file tooth and cutter tooth, filings very easily embeds wherein, thereby scratch manufactured plane, the roughness value of processing plane is increased, especially when processing softer material, this phenomenon is more outstanding, and meanwhile, the filings embedding between topping is difficult for taking out, often to waste a lot of time, have a strong impact on working (machining) efficiency.Fine finishining is not passed through in the side of traditional oils dead smooth cut file, if when workpiece has mutually perpendicular two sides, processing is when one side wherein, another machined surface of can damaging.The manufacturing process of traditional oils dead smooth cut file is for first processing topping part, heat-treating quenches again improves hardness, in heat treatment process, will certainly cause the distortion such as file epirelief, recessed, distortion, have a strong impact on the performance of file, cannot adapt to high-precision plane machining.

Summary of the invention

Goal of the invention of the present utility model is exactly the deficiency that overcomes traditional oils dead smooth cut file, can obviously improve the precision of part processing plane, especially can significantly reduce the surface roughness value of plane, and be difficult for embedding filings, substantially without cleaning filings, save time, raise the efficiency.

Goal of the invention of the present utility model is achieved through the following technical solutions: described glossy file is to use high-speed steel bars (HSS), being commonly called as " white steel bar " makes, concrete processing method is the processing method that adopts the galvano-cautery such as line cutting, high-speed steel bars is cut into the sheet that thickness is 3mm-4mm along its length, on cut surface, form the minute protrusions of countless 0.5um-2um, the present utility model utilizes these minute protrusions to carry out machining as topping exactly, then on the sheet high-speed steel bars of well cutting, process file handle part, form complete file.

Above-described glossy file spreads all over minute protrusions and the pit of 0.5um-2um on working face, and the smear metal in process is Powdered, is difficult to embed between topping, so can process the plane of roughness value Ra1.6um-Ra0.8um.

Above-described glossy file, the two sides through line cutting are not the original smooth grinding face of high-speed steel bars, when orthogonal two planes of processing, in processing, wherein during one side, can not scratch another plane.

Above-described glossy file, two working faces that cutting forms through line, its linearity and flatness can be controlled at 0.01mm-0.02mm, so can the exigent high-precision plane of processing plane degree.

In addition, high-speed steel bars has the size of different size, selects the high-speed steel bars of different size can make the glossy file of various width specifications, to adapt to the processing of various width planes.

In sum, the utility model has the following advantages.

1. in process, filings is difficult for embedding, and can process the plane of roughness value Ra1.6um-Ra0.8um, saves the time of cleaning file simultaneously, raises the efficiency.

2. file side is smooth flat, can process orthogonal two planes, and does not destroy the precision of adjacent surface.

3. the working face linearity of this file and flatness can guarantee at 0.01mm-0.02mm, can adapt to the processing of high precision plane.

Accompanying drawing 2 is top views of accompanying drawing 1.

Accompanying drawing 3 is A-A profiles of accompanying drawing 2.

Accompanying drawing 4 is B place partial enlarged drawings of accompanying drawing 3.

Accompanying drawing 5 is schematic diagrames that the utility model is processed mutual vertical plane workpiece.

Embodiment

Below by embodiment, by reference to the accompanying drawings, the utility model is described further.

Embodiment: the utility model selects the high-speed steel bars (HSS) of HRC60-70 to make, through line, be cut into the sheet that thickness is 3mm-4mm, and process file handle 13, wherein two faces through line cutting form working face 11, the two sides through line cutting processing is not two sides 12, and two sides 12 are the original smooth grinding face of high-speed steel bars.The minute protrusions 14 and the pit 15 that on working face 11, spread all over 0.5um-2um, form the cutter tooth of this glossy file, because cutter tooth is tiny especially, so the filings forming in processing is powdered, and is difficult to embed between cutter tooth.After glossy file line described in the utility model has cut without heat-treating quenching, can not produce thermal deformation, so can guarantee very high linearity and flatness, reach 0.01mm-0.02mm, so the high precision plane of the efficient machined surface roughness value Ra1.6um-Ra0.8um of energy.Glossy file described in the utility model has smooth two sides 12, so can process the workpiece with two mutually perpendicular planes 2 shown in accompanying drawing 4, can not damage finished adjacent surface when one of them plane of processing.
