Greatly, seem more and more difficult using existing high speed steel material broaching tool broaching tongue-and-groove, it is necessary to develop the drawing of new material, new construction
Knife.
Existing disclosed inserted tooth type or clip type broaching tool patented technology, the positioning method of blade are plane positioning, are determined
Position clamping structure is complicated, and structure size is larger, is unable to satisfy requirement；Or processed again after fixturing blade, blade is not mutual
It is transsexual, it can not achieve quick change.Aero-engine disk ring part tongue-and-groove size is typically small, needs to participate in cutting for two sides
It slots for broaching tool, existing technology can not solve clip type hard alloy fluting broaching tool and have interchangeability, realize asking for quick change
Topic.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of clip type broaching tools, solve aero-engine disk ring
The problem of part tongue-and-groove broaching clip type hard alloy fluting cutter bit positioning and clamping.
In order to achieve the above object, the present invention includes broaching tool tool apron, and several mounting grooves, mounting groove are offered on broaching tool tool apron
It is inside fixed with blade, the blade of blade is higher than broaching tool tool apron, and blade is fixed in mounting groove by wedge-shaped briquetting, and blade side is
Convex V-type face is provided with the recessed V-type face matched with the convex V-type face of blade in mounting groove, and the top surface of blade and two sides are stretched
Mounting groove out.
Through-hole is provided on wedge-shaped briquetting, wedge-shaped briquetting is fixed in mounting groove by housing screw.
The angle δ in the angle theta in recessed V-type face and convex V-type face is 110 °~130 °.
The height dimension of each mounting groove bottom positioning surface is incremented by by design rise per tooth.
The vertical angle β in recessed V-type face and wedge-shaped briquetting contact surface in mounting groove is taken as 10 °~15 °.
The included angle X of the non-inclined-plane in the side of wedge-shaped briquetting, inclined-plane and vertical plane is 10 °.
The cutter tooth width B of blade is 10~20mm.
The conductor width B1 of mounting groove inner blade is 0.8~1.2mm smaller than the size of cutter tooth width B.
The width dimensions of wedge-shaped briquetting are 0.6~1.5mm smaller than the size of cutter tooth width B.
Blade is made of cemented carbide material, has anterior angle, relief angle and side relief angle on blade.
Compared with prior art, the present invention is equipped with multiple blades on broaching tool tool apron, is removable between blade and tool apron
Connection is unloaded, enables the blade to exchange, and is able to carry out quickly assembling and debugging, installation is stretched out in the top surface of blade and two sides
Slot part cutter hub width, the positioning method make the broaching tool compact-sized, can be processed inside deep enough tongue-and-groove.Of the invention
Broaching tool tool apron may be reused, and shortens the manufacturing cycle of broaching tool, reduces manufacturing cost.
Further, blade of the invention is made of cemented carbide material, and the material is more than common high speed steel material
It is wear-resisting, extend the service life of broaching tool.
