Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of milling cutter, particularly a kind of inserted-blade type face and side cutter.
Background technology
Face and side cutter is called for short three swords: three cutting edges all have relief angle, and cutting edge is sharp, cut brisk.Face and side cutter is the machine tool of standard, usually uses on sleeping milling machine, is generally used for milling groove and step.
The current face and side cutter overwhelming majority is all-in-one-piece HSS sawblade milling cutter, and small part is welded hard-alloy metal saw.The former limit due to the performance of material and the design feature (sheet) of milling cutter itself, its cutting speed allowed is lower, generally can only work under the cutting speed of 30 to 50m/min, in addition, because this kind of milling cutter adopts monoblock type quenching, and must HRC61 to HRC63 be reached by its hardness of standard-required, therefore toughness and impact strength are all poor, in use and easily to forge a knife phenomenon, therefore general miller is for the purpose of careful, mostly adopt manual feed when using face and side cutter processing work, thus reduce efficiency; And welded hard-alloy face and side cutter, be generally be cutter hub with structural alloy steel, carbide chip in welding, forms through fine finishining, although the intensity of its cutting speed, efficiency and cutter tooth is improved, manufacture difficulty is larger.A face and side cutter more than ten tooth, at most tens teeth at least, if there have several tooth to weld in welding process to be askew, this is to just having scrapped, if in use there is several tooth to break, this cutter has just been scrapped.Therefore, this kind of face and side cutter is generally only used for being processed with non-ferrous metal or cast iron, which hampers applying of welded type face and side cutter.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and more allowing blade replacement is convenient to provide one, the inserted-blade type face and side cutter of applied range.
The purpose of this utility model realizes by following technical proposal: a kind of inserted-blade type face and side cutter, comprise blade, cutter hub and the handle of a knife being arranged at cutter hub central part, described cutter hub is disc-shaped, it is characterized in that, described cutter hub circumferentially offer three open slots uniformly, three described open slots are by point formation three flanges such as cutter hubs, described each flange is all provided with the cutterhead of arc-shaped, described cutterhead is made up of the tooth row that two are parallel to each other, and between two tooth rows, leave the insert groove installing blade, described tooth row have the equally distributed gear teeth, the gear teeth that described blade is arranged at adjacent tooth row snap in insert groove, described flange offers pin-and-hole, the lower surface of described cutterhead have corresponding with pin-and-hole and insert the pin of pin-and-hole.
The cutter hub of the assembling of this inserted-blade type face and side cutter, cutterhead and blade are that separable assembled forms, and this design can be used in the difform workpiece of different materials, and range of application expands.
In above-mentioned a kind of inserted-blade type face and side cutter, the lower surface of described cutterhead is the circular arc matched with flange outer wall, and cutterhead lower surface offers mounting groove, described flange outer wall has the mounting bar snapping in mounting groove, is connected by screw between described cutterhead and cutter hub.
In above-mentioned a kind of inserted-blade type face and side cutter, in described each open slot, be provided with the limited block that can limit cutterhead and move radially.Limit cutterhead by limited block between adjacent cutterhead to move radially.
In above-mentioned a kind of inserted-blade type face and side cutter, the both ends of described cutterhead lower surface offer the draw-in groove snapping in limited block.This structural design can make fit tightly together between adjacent cutterhead.
Compared with prior art, it is convenient that this inserted-blade type face and side cutter has more allowing blade replacement, the advantage of applied range.
