Abstract
The present utility model provides a double-head rotation filing meaning that it comprises another rotation filing head on the other end of a rotation filing, wherein the middle part is a filling handle, the structures and shapes of both rotation filing heads may be same or different. The advantages of the present utility model are that costly hard alloy materials are saved, then the cost is reduced, for example, the cost of a double-head hard alloy rotation filing is equal to 2/3 of two common whole hard alloy rotation filing with the same function.
Description
Technical field
The utility model relates to a kind of a kind of rotary file of milling tools.
Background technology
Carbide rotary tool is the indispensable instrument of pincers worker mechanization, purposes is very extensive, more remarkable in industrial department results of use such as aviation, boats and ships, automobile, machinery, chemical industry, can be used for processing cast iron, cast steel, carbon steel, steel alloy, stainless steel, hardened steel, copper and aluminium etc.Rotary file can replace being with the little emery wheel processing of handle, no emery wheel dust pollution.Production efficiency improves ten times than also raising the efficiency 3～5 times of tool lifes with little emery wheel processing than high-speed steel tool than improving tens of times with general manual file processing, improves more than 50 times than the durability with little emery wheel.The bore area of metal die cavity that can the fine finishining different shape and fine finishining machinery part.But because carbide rotary tool material in the market is comparatively expensive, the carbide rotary tool production cost is higher, and has only one the rotary file head is arranged, and the other end is a staight shank, has wasted and has protected expensive Hardmetal materials, and is very uneconomical.
Summary of the invention
For solving foregoing problems, the utility model provides a kind of double end rotary file, promptly in the other end of rotary file file head, also is shaped on the rotary file head, and the centre is a grip shank, and the rotary file header structure shape at two can be identical or inequality.
The utility model has the advantages that, saved valuable Hardmetal materials, reduced cost, double end carbide rotary tool cost only be equivalent to two said functions whole hard alloy rotary file commonly used 2/3.Both economical and practical, use more convenient again.
Description of drawings
Accompanying drawing 1 is construction profile figure of the present utility model.
Accompanying drawing 2 is another kind of construction profile figure of the present utility model.
Accompanying drawing 3 is existing rotary file outline drawings.
Accompanying drawing 4 is rotary file outline drawings of existing another kind of shape.
The specific embodiment
See also shown in Fig. 3,4, existing rotary file planform, one is that 1, one on rotary file head is a tang 2; Accompanying drawing 3 is in former rotary file file 1 other end, also is shaped on file 3, and accompanying drawing 4 is that two of another kind of rotary file file header structure all has rotary file file head.
Claims (1)
1, a kind of double end rotary file is characterized in that: the other end at rotary file file head, also be shaped on the rotary file head, and the centre is a grip shank, the rotary file header structure shape at two can be identical or inequality.
