The use effect is good.

Description

Curved surface machining tool for square strip material

Technical Field

The invention relates to a curved surface processing cutter for square bar materials, belonging to the field of square bar material processing equipment.

Background

In the prior art, the existing square strip material is a small strip-shaped wood material with a square cross section, which is supported by cutting and processing wood materials, so as to process small wooden products, such as chopsticks, handles of shoe brushes, wooden scratchers, bookmarks and the like.

The existing square bar is generally fixed on a machine tool when curved surface machining is carried out on the square bar, a cutter is clamped through a chuck on the machine tool, then the curved surface machining is carried out on the square bar through the cutter, however, the curved surface machining cutter used by the existing square bar can only machine one curved surface, and then when the curved surfaces with other shapes are machined, the cutter needs to be taken down and replaced by a new cutter, so that the cutter needs to be replaced frequently, the operation is simple, the time for machining the square bar is prolonged, and the working efficiency is low, therefore, the curved surface machining cutter of the square bar is needed to solve the problems.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a curved surface processing cutter for a strip material, and solves the problems in the background technology.

In order to achieve the purpose, the invention is realized by the following technical scheme: the curved surface processing cutter for the square strip materials comprises a main cutting edge, wherein the upper end of the main cutting edge is integrally connected with a cutter bar, the upper end of the cutter bar is integrally connected with a cutter handle, fillets are arranged at the upper end and the lower end of the main cutting edge and are a lower fillet cutting edge and an upper fillet cutting edge respectively, and the upper fillet cutting edge is located above the lower fillet cutting edge.

The invention has the beneficial effects that: the curved surface processing cutter for square bars of the invention realizes the processing of the curved surface of the appearance of a workpiece by the main cutting edge by processing the upper and lower rounded cutting edges at the upper and lower ends of the main cutting edge, integrates various functions by processing the chamfers of the upper and lower curved surfaces of the workpiece by the lower rounded cutting edge and the upper rounded cutting edge, can process various curved surfaces by using one cutter, thereby reducing the disassembly frequency of the cutter, reducing the workload, reducing the error rate, improving the working efficiency, having good use effect, solving the problems that the curved surface processing cutter used by the existing square bars can only process one curved surface at a time, and then needs to take down the cutter and change a new cutter when processing curved surfaces with other shapes, thereby needing frequent cutter replacement, having simple operation and prolonging the processing time of the square bars, the working efficiency is low.

FIG. 1 is a schematic structural view of a curved surface machining tool for square bars according to the present invention;

FIG. 2 is an enlarged view of the portion A of the curved surface machining tool for square bars according to the present invention;

in the figure: 1-main cutting edge, 2-cutter bar, 3-cutter handle, 4-lower fillet cutting edge and 5-upper fillet cutting edge.

Detailed Description

Before the embodiments are described in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of embodiments in other forms of implementation. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of "including," "comprising," "having," and the like, herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. In particular, when "a certain element" is described, the present invention is not limited to the number of the element being one, and may include a plurality of the elements.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: the curved surface processing cutter of square bar material, including main cutting edge 1, 1 upper end an organic whole of main cutting edge is connected with cutter arbor 2, 2 upper end an organic whole of cutter arbor are connected with handle of a knife 3, the fillet has been done at main cutting edge 1 upper and lower both ends, and be lower fillet cutting edge 4 and last fillet cutting edge 5 respectively, it is located fillet cutting edge 4 top down to go up fillet cutting edge 5, fix handle of a knife 3 in this device on the outside lathe through the chuck, then it is rotatory to drive this device through the operation of lathe, accomplish the processing to work piece appearance curved surface through main cutting edge 1 afterwards, the processing of curved surface chamfer about the work piece is accomplished through lower fillet cutting edge 4 and last fillet cutting edge 5, the purpose of collecting multiple functions in an organic whole has been realized, need not to dismantle the change to the cutter, cutting error is reduced, and work.

The concepts described herein may be embodied in other forms without departing from the spirit or characteristics thereof. The particular embodiments disclosed should be considered illustrative rather than limiting. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. Any changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
