Abstract

The invention relates to an alloy saw chain. The alloy saw chain comprises a plurality of middle guide teeth which are evenly arrayed, the top portions and the bottom portions of every two adjacent middle guide teeth are alternately provided with connecting pieces and bent connecting pieces, a tool rest is fixed to the side portion of each bent connecting piece, an alloy tool bit is fixed to each tool rest, and the connecting pieces and the bent connecting pieces are alternately arranged on the upper sides and the lower sides of the middle guide teeth and are connected with the middle guide teeth through rivets to form a chain structure. The alloy saw chain is stable in structure, the structure method that the connecting pieces, the tool rests and the bent connecting pieces are matched with one another is adopted, each bent connecting piece is bent to form two fixing plates which form a right angle and are divided into a bottom plate and the tool rest fixing plate, the bottom plates are connected with the middle guide teeth through rivets, the tool rest fixing plates fix the tool rests through clamping platforms, welding and thermal processing are sequentially conducted through high-temperature welding materials at the temperature exceeding the thermal processing temperature, a tool bit clamping groove is formed between every two adjacent arc-shaped protrusions, the alloy tool bits in different styles can be installed in the tool bit clamping grooves, and therefore the hardness and firmness of the alloy tool bits are ensured, and the strength of the saw chain is also ensured.

Description

A kind of alloy saw chain

Technical field

The present invention relates to a kind of alloy saw chain.

Background technology

Saw chain is a kind of very convenient and powerful portable instrument, has the ability of replaceable chain, but existing chain is commercially mainly to cut timber, and to hard wood, light-weight brick, tree root and helpless compared with soft mineral etc.The producer of existing research and development product, be not that service life of chain is short, fall cutter head exactly, product is extremely immature.The mainly contradiction of heat treatment temperature and welding temperature, as first heat treatment then welding temperature be enough to reduce knife rest hardness, have a strong impact on the bulk strength of chain.Otherwise then the alloy cutter head tip-off welded can be come, and the contact area of welding is little, positional stability is poor.Production efficiency is low, service life is short, customer using cost is high.This defect could not be walked around in global same provisional capital, and being therefore badly in need of one can according to sawing Material texture, assemble various alloy cutter head and the saw chain of stable performance to meet the demand of different user.

Summary of the invention

For solving the problems of the technologies described above, the invention provides the alloy saw chain that a kind of structure is simple, easy to use, the alloy cutter head of different money can be assembled.

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.

Detailed description of the invention

Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.

As Figure 1-4, a kind of alloy saw chain, comprise some arranged in a uniform in lead tooth 1, top and the bottom of leading tooth 1 in adjacent two have been arranged alternately brace 2 and bending brace 3, the sidepiece of bending brace 3 is fixed with knife rest 4, knife rest 4 is fixed with alloy cutter head 5, leads tooth 1 in described and up and down the brace 2 that is arranged alternately of both sides and bending brace 3 connect into chain structure by rivet 6.
