Abstract

The utility model discloses a cutter convenient to control sword width, including the handle of a knife, the one end of handle of a knife has a plurality of sword teeth, and the handle of a knife closes on the lateral wall of sword tooth have with sword tooth assorted chip groove, an at least lateral wall top of chip groove has one and controls the wide flute, should control the wide flute and be located the side of week sword, the degree of depth and the width of accuse wide flute all are less than the degree of depth and the width of chip groove. Each chip groove has one and only one width control groove. The width control grooves on the adjacent peripheral edges are all positioned on the same side of the peripheral edges. The cutter can accurately control the edge width during manufacturing, and the yield is ensured.

Description

Cutter convenient to control width of edge
Technical Field
The utility model belongs to the technical field of the cutter and specifically relates to a cutter convenient to control sword is wide.
Background
A tool is a tool used for cutting machining in machine manufacturing, and is also called a cutting tool. A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine.
In the production of milling cutters, in particular end mills, the width of the cutting teeth of the end mill is determined by the width of the chip flutes. When the cutter tooth and the chip groove are machined, the grinding wheel is used for machining the cutter tooth and the chip groove, but the grinding wheel is abraded in the using process, so that the width of the chip groove cannot be accurately controlled in the later use process, and the edge width of the cutter tooth is influenced. Thereby resulting in a reduction in the yield of the cutter production.
Disclosure of Invention
In view of the above, it is desirable to provide a cutting tool with stable quality and high yield, and the cutting edge width can be easily controlled.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a cutter convenient to control sword width, includes the handle of a knife, the one end of handle of a knife has a plurality of sword teeth, and the handle of a knife is close to the lateral wall of sword tooth and has the chip groove with sword tooth assorted, at least a lateral wall top of chip groove has one and controls the wide groove, should control the wide groove and be located the side of week sword, the degree of depth and the width of accuse wide groove all are less than the degree of depth and the width of chip groove.
Furthermore, each chip groove has only one width control groove.
Furthermore, the width control grooves on the adjacent peripheral edges are all positioned on the same side of the peripheral edges.
Further, the depth of the width control groove is smaller than 1/3 of the depth of the chip groove.
Further, the width of the width control groove is smaller than 1/3 of the width of the chip groove.
Further, the helical angle of the width control groove is equal to that of the chip groove.
Compared with the prior art, the utility model discloses following beneficial effect has: the width of the cutting edge can be accurately controlled and the yield can be ensured by firstly processing the width control groove and then processing the chip groove when the chip groove is processed by the cutter.
In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
In the figure: 1-knife handle, 2-knife tooth, 3-chip groove, 4-circumferential edge and 5-width control groove.
Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
As shown in figure 1, the cutter convenient for controlling the blade width comprises a cutter handle 1, wherein one end of the cutter handle 1 is provided with a plurality of cutter teeth 2, the side wall of the cutter handle 1 close to the cutter teeth is provided with chip flutes 3 matched with the cutter teeth, and naturally, peripheral blades 4 which are equal to the cutter teeth in number and are integrated with the cutter teeth 2 are formed after the chip flutes 3 are machined on the side wall of the cutter handle 1.
The top of one side wall of the chip groove 3 is provided with a width control groove 5, the width control groove 5 is positioned at the side of the peripheral edge 4, and the depth and the width of the width control groove 5 are both smaller than those of the chip groove 3.
In this embodiment, the width control grooves 5 on adjacent peripheral edges 4 are all located on the same side of the peripheral edge.
In this embodiment, the depth of the width-controlling groove 5 is less than 1/3 of the depth of the chip flute 3.
In this embodiment, the width of the width control groove 5 is smaller than 1/3 of the width of the chip flute 3.
In this embodiment, the helix angle of the controlled width flute 5 is equal to the helix angle of the chip flute 3, i.e. they are parallel.
In order to control the edge width of the cutter tooth, a small grinding wheel is used for processing a width control groove before a chip groove is processed. And then, a grinding wheel is used for processing the chip groove, so that the edge width of the cutter tooth is preset through the width control groove, when the chip groove is processed, even if the size of the grinding wheel is abraded, only the width control groove is ground by the grinding wheel, the loss is the width control groove, and the edge width of the cutter tooth cannot be influenced by the grinding wheel with deformed size, so that the accuracy of the edge width is ensured, and the yield of cutter production is improved.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
