Alloy saw chain of the present invention, comprise some arranged in a uniform in lead tooth, top and the bottom of leading tooth in adjacent two have been arranged alternately brace and bending brace, the sidepiece of bending brace is fixed with knife rest, knife rest is fixed with alloy cutter head, leads tooth in described anti-bounce-back and brace that up and down both sides are arranged alternately becomes chain structure with bending brace by rivet interlacement.
Alloy saw chain of the present invention, tooth is led and up and down the brace that is arranged alternately of both sides and bending brace are equipped with two rivet holes in described, brace with in lead the rivet hole outer of tooth contact and bending brace with in lead tooth contact rivet hole outer be equipped with ring packing ring recess, be equipped with sealing ring in ring packing ring recess.
Alloy saw chain of the present invention, described bending brace comprises the base plate and knife rest fixed head that are bent into right angle, base plate is led on tooth in being fixed on by rivet, the lateral wall both sides of knife rest fixed head are equipped with an outwardly directed chuck, the two ends of described knife rest are equipped with a draw-in groove be fastened in chuck, and the contact position of knife rest and knife rest fixed head is by being welded and fixed.
Alloy saw chain of the present invention, the cross section of described chuck is rectangle, and the width of chuck is less than the width of knife rest fixed head.
Alloy saw chain of the present invention; the lateral wall both sides of described knife rest are equipped with two arc convex; be used for limiting cutting output and anti-bounce-back; cutter head clip slot is all formed between two arc convex of left end and between two arc convex of right-hand member; the back of described alloy cutter head is fastened in cutter head clip slot; the contact position of alloy cutter head and arc convex is by being welded and fixed, and arc convex alloy cutter head plays a very good protection.
Alloy saw chain of the present invention, the angle between the stationary plane that described arc convex contacts with alloy cutter head and knife rest rear end face is less than 90 degree.
Compared with prior art beneficial effect of the present invention is: alloy saw chain stabilized structure of the present invention, have employed brace, knife rest, the frame mode that bending brace coordinates, bending brace is bent into the fixed head that two are mutually right angle, be respectively base plate and knife rest fixed head, base plate by rivet with in lead tooth and be connected, knife rest fixed head is by chuck immovable support, cutter head clip slot is all formed between adjacent two arc convex, the alloy cutter head of different money can be installed in cutter head clip slot, both hardness and the firmness of cutter tip had been ensure that, in turn ensure that the intensity of chain, greatly reduce the weld interval of alloy cutter head.
