Description

Fettling knife

Technical Field

The utility model relates to a fettling instrument field, especially a fettling sword

Background

After the sanitary ware blank is demoulded, blank trimming and edge scraping are needed at the blank die seam and the water chestnut positions.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fettling sword to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a fettling sword, the fettling sword includes tool bit and handle, the top in tool bit cross-section is the arc, be equipped with in the middle of the tool bit through the opening on tool bit top, open-ended front end is for repairing the base mouth, it is square to repair the base mouth, it is in to repair the base mouth the opening at the bottom of the tool bit upper base is greater than the opening at the bottom of the tool bit upper base opening with be equipped with the arc transition between the opening at the bottom of the tool bit, the tool bit still including be located the top of tool bit and stride across repair the location line of base mouth. The symmetrical side surfaces of the cutter head are provided with screw holes and fastening pieces, and two ends of the positioning line are fixed on the fastening pieces.

Preferably, the symmetrical side surfaces of the cutter head are also provided with positioning grooves along the path direction of the positioning lines so as to position the positioning lines not to displace along with the action of external force.

Preferably, the positioning wire is a metal wire, and a stainless steel wire is selected.

Preferably, a through hole is formed in the middle of the handle, so that the weight of the fettling knife is reduced, and the fettling knife is light and convenient to use.

Preferably, the two side faces of the handle are concave cambered surfaces, so that the handle is convenient to hold by hand.

Preferably, the fettling knife is made of stainless steel or copper, and because the blank is wet, if an iron wire is used, the fettling knife can rust, and the smoothness of the surface of the blank is affected.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses according to the radian preparation of body water chestnut position, convenient to use is swift, improves fettling efficiency and quality greatly, the utility model discloses still also have the repairing action to the body die seam.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1 tool bit, 11 openings, 111 blank trimming openings, 12 positioning lines, 13 screws, 2 handles, 21 through holes and 22 arc-shaped surfaces.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a fettling sword, has certain thickness, includes the upper base and goes to the bottom, the fettling sword includes tool bit 1 and handle 2, the top of 1 cross-sections of tool bit is the arc, be equipped with in the middle of the tool bit 1 through the opening 11 on 1 top of tool bit, the front end of opening 11 is fettling mouth 111, and its size matches the diamond corner of blank, fettling mouth 111 is square, fettling mouth 111 is in the opening 11 of 1 upper base of tool bit is greater than the opening 11 of 1 lower bottom of tool bit be equipped with the arc transition on 1 upper base of tool bit 11 with 1 lower bottom of tool bit is equipped with between the opening 11, tool bit 1 still including being located the top of tool bit 1 and strideing across the location steel wire of

fettling mouth

111, 1 symmetrical side of tool bit is equipped with screw and screw 13, the both ends of location steel wire are fixed on the screw 13. In order that the positioning line 12 does not displace along with the action of external force, the symmetrical side surfaces of the tool bit 1 are also provided with positioning grooves along the path direction of the positioning line 12. In order to facilitate the force application when the fettling knife is held by a hand, the two side surfaces of the handle 2 are concave cambered surfaces, and in order to reduce the weight of the fettling knife, the fettling knife is light and convenient to use, and a through hole 21 is formed in the middle of the handle 2. When the tool bit is used, the upper bottom surface of the tool bit 1 faces a blank to be repaired, the tool bit 1 passes along the diamond corners of the blank, and the blank of the diamond corners is repaired into the smooth arc-shaped surface 22 due to the arc transition effect of the arc positioning line 12 and the blank repairing opening 111.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
