To sum up, the utility model discloses a beneficial technological effect does:

1. by arranging the tool holder and the blades, the cutting force is shared by the four blades when the trepanning tool is used for processing, the segmented cutting of materials can be realized, the single cutting allowance is small, and therefore the tool loss is small;

2. through the arrangement of a 2-degree draft angle, the four tool holders are integrally in a horn mouth shape, so that the material can be conveniently dropped;

3. through the setting of automatic liftout mechanism, after accomplishing the cutting, the liftout piece pushes out the cutter body with the cutting waste material under the promotion of spring to can let the cutter carry out processing on next step, reduce the time that the staff cleared up the cutter iron fillings.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, for the utility model discloses an automatic material jacking sword that falls of spot facing work, including handle of a knife 1 and the cutter body 2 that is connected with handle of a knife 1, handle of a knife 1 adopts the design of BT-50 tapering. The cross-section of cutter body 2 is circular, and the inside hollow design of cutter body 2, four central apopores 21 have been seted up to circumference equidistance interval on the terminal surface of cutter body 2 to realize central water function. The central water outlet is beneficial to the discharge and heat dissipation of cutting scraps, and the production efficiency is improved.

Referring to fig. 3 and 4, the cutter body 2 is connected with four cutter holders 3 at equal intervals in the circumferential direction on the circumferential side surface away from one end of the cutter handle 1, each cutter holder 3 is provided with a blade 4, the width of the front cutting edge of each blade 4 is 4mm, and each blade 4 is provided with a 7-degree back angle. When the trepanning cutter is used for machining, cutting force is shared by the four blades 4, segmented cutting of materials can be achieved, single cutting allowance is small, and therefore cutter consumption is small.

Referring to fig. 2 and 3, in the embodiment, the included angle between the planes of the two symmetrical blades 4 is 180.1 °, and the two blades are designed to be non-centrosymmetric, so that material jamming is prevented. Every cutter holder 3 all is equipped with 2 draft angles, and four cutter holders 3 are whole to become the bell mouth shape, are convenient for fall the material. The height of the part of the cutter holder 3 extending out of the cutter body 2 is 25mm, a material containing groove 5 for containing cutting waste materials is formed between the part of the cutter holder 3 extending out of the cutter body 2 and the end surface of the cutter body 2, and the waste materials with the thickness of 20mm can be contained at most.
