Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative work, all belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a durable long-life cutter, including: the utility model provides a durable high life cutter, including installation piece 1, logical groove 12 that link up around installation piece 1 bottom is equipped with, the vertical splint 3 that are equipped with respectively in installation piece 1 left and right sides bottom, be equipped with rectangular hole 31 on the splint 3, it is equipped with polygon blade disc 2 to lead to the inslot 12, polygon blade disc 2 center department is equipped with through-hole 23, evenly be provided with a plurality of spacing grooves 13 around the edge on the polygon blade disc 2 both sides, installation piece 1 side bottom is equipped with a plurality of screw holes 11, be equipped with the first fixing bolt 111 that matches with spacing groove 13 in the screw hole 11, the rectangular hole 31 and the through-hole 23 that pass both sides splint 3 are equipped with second fixing bolt 4, through setting up regular pentagon polygon blade disc 2 cooperation rectangular hole 31, can descend and rotate other one side cutting edge in rectangular hole within range through the instrument after polygon blade disc 2 one side cutting edge or sword angle damage or after overheated, the rising is fixed the use again, reached the purpose of repairing and prolonging cutter life fast high-efficient after cutter damage or overheated, and reduced manufacturing cost simultaneously.

Referring to fig. 1 and 3, the polygonal cutter head 2 is a regular pentagon, and through practical experiments, the regular pentagon has the highest cost performance in terms of the number of edge angles and cutting effects, and one side of the top end of the polygonal cutter head 2 is perpendicular to the mounting block 1, so that one edge angle is always opposite to the lower side.

Referring to fig. 1, a front-rear through limiting groove 13 is formed in the top end of the through groove 12 of the mounting block 1, the size of the limiting groove 13 is matched with the thickness of the polygonal cutter head 2, and one side of the polygonal cutter head 2 is clamped into the limiting groove 13 so as to be fixed in the cutting direction.

Referring to fig. 1 and 3, a plurality of positioning grooves 22 parallel to the sides are formed in two sides of the polygonal cutter head 2, connecting pads 5 are arranged in the positioning grooves 22, so that the fixing effect is further improved, the occurrence of chatter is reduced, the connecting pads 5 are made of heat-conducting rubber materials, the contact area between the mounting blocks and the polygonal cutter head can be increased, the heat-conducting effect is enhanced, and the service life is prolonged.

The working principle is as follows: the polygonal cutter disc 2 finishes cutting work by using the edge angle at the bottommost end, the cutting direction is perpendicular to the polygonal cutter disc 2, when a certain edge angle is damaged or overheated, an operator unscrews the first fixing bolt 111 and the second fixing bolt 4, uses a clamping tool to move the polygonal cutter disc 2 downwards within the range of the strip hole 31, then rotates the polygonal cutter disc 2 downwards to move other edge angles downwards, moves the polygonal cutter disc 2 upwards, clamps the polygonal cutter disc into the limiting groove 13, and fixes the polygonal cutter disc again.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various 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.
