Abstract
Produce the method for saw blade.Owing to will produce saw blade, a continuous metal sheet 10 is followed at first by a quenching stove 11, and sawtooth 13 is formed by grinding machine 12 grindings, and afterwards, this strip metal sheet is by by two grinding machines that parallel emery wheel constituted, and by the end face of emery wheel in the grinding of sheet metal both sides.The outside of the sawtooth that side direction is widened is then by another grinding machine 15 processing.Be cut into the saw blade of all lengths through this strip metal sheet after the above-mentioned processing.
Description
What this invention was said is the method for making saw blade.In manufacture process, at first make sawtooth along a vertical limit of a strip metal sheet, to follow, this strip metal sheet passes through in the middle of two emery wheels, makes the place that does not have sawtooth than the serrate local material that more manyed under the mill.
Swiss Patent (numbering 269567) has been revealed a kind of method of making saw blade.In this process, the wedge-shaped crevice of the sheet metal of a length-specific by forming together by the surface of two grinding roller bearings because the axis of two grinding roller bearings constitutes an acute angle, so that the profile of this sheet metal formation wedge shape.Then, thicker longitudinal edge is worn into sawtooth by another grinding machine on the wedge metal sheet.In this process, the distance between the axis of two grinding roller bearings can change, but this change is difficult., the distance between this axis is the wearing and tearing with compensation grinding roller bearing that need change.
Make in the saw blade method according to the another kind of being revealed in the Swiss Patent (numbering 235076), therefore they have used the spinning mill of the normal slope of two axis and that bonding jumper, and the two sides of only touching that strip metal sheet, the edge of two emery wheels is in this edge and separates nearest position.The shortcoming of this process is to have only the edge of emery wheel to be used for grinding, and this has accounted for and can be used for the sub-fraction of emery wheel surface area of grinding sheet metal.
In above example, the sheet metal of the prefabricated length of a rule is single processing.
The objective of the invention is to provide the method for the good saw blade of a kind of quality bills of materials economically.
Another object of the present invention is that a kind of method that makes full use of emery wheel and exhaust emery wheel as far as possible equably will be provided.
The another one purpose be can be easily under the situation of emery wheel loss the slit between the adjustment emery wheel again.
According to method of the present invention, the end face of two emery wheels parallel to each other is the two sides of grinding sheet metal respectively.The periphery of two emery wheels constitutes a tapered zone simultaneously, comes the side of grinding sawtooth.
Emery wheel does not have the place of sawtooth to grind off more material than in serrate place on sheet metal, the result, and just there has been the wedge shape of wearing into from the firm material of script at the sawtooth position.
The whole piece sheet metal can pass through a glowing furnace easily before making sawtooth.To in being arranged, the grinding process of the sawtooth of high rigidity more be removed on decarburization top layer that quenching process forms.Moreover the shape of the sawtooth of being worn into will guarantee that sawdust can more easily slide away, the result, and saw blade just has higher cutting power.
Now introduce another aspect of the present invention with peculiar property: be tailored out the saw blade of Len req behind a plurality of processing stations of a successional rectangular process, in this case, saw blade be continuous sheet metal produce on the production line of process.Each and every one treating stations can be programme controlled thereby can make different zigzag fashions arbitrarily, the not ipsilateral profile and the different side angles of saw blade.And we also can utilize single production line to produce different types of saw blade.Another advantage is need not one by one each and every one saw blade be put in the machine fixedly to process.
Saw blade of the present invention can be used for handsaw or power saw.The end of saw blade also can be connected to each other and be applied to band saw.With the saw body is that the annular saw of a hard plate is different, and saw blade is a flexible rack, and therefore, its raw material can be supplied with becoming.After untiing, a volume insulating material of having stored is placed into glowing furnace.Through after the quenching process, further processing is only carried out under the situation that sheet material launches, because material hardens, it is unpractiaca that minor axis curls.
Referring now to accompanying drawing preferred embodiment of the present invention is illustrated.
Figure one is a skeleton diagram of producing the saw blade process;
Figure two is sawtooth bonding jumper skeleton diagrams by the grinding station;
Figure three is saw blade cross sections along the line III-III shown in the figure one;
Figure four is saw blade cross sections along the line IV-IV shown in the figure one.
In one li in figure, a bloom 10 is by behind the glowing furnace 11, and air hardening is carried out in cooling thereupon.Whole piece steel disc 10 is narrow rectangle.
After finishing quenching, grinding machine 12 grinds sawtooth 13 along a longitudinal edge of whole piece steel disc 10.Then, the whole piece steel disc is by the grinding machine 14 shown in figure two.And the crown both sides of sawtooth are by another grinding machine 15 side angles.Then, a cutting machine (not showing in the drawings) can cut into the required length of saw blade with the continuous steel disc 10 of this bandlet shape.
When steel bar 10 enters and leaves grinding machine 14, by roller bearing 24(figure one) the support bottom that it slides.The support roller bearing then is placed on the frustoconical position 23 of allowing emery wheel 16 and 17 and can polishing on the height on two sides of steel bar top sawtooth.Do not have the position of sawtooth as for steel bar, then come grinding by parallel emery wheel end face 18.The shape of cross section of the saw blade of making is generally as shown in figure three and the figure four.The steel bar both sides do not have the part 10a of sawtooth thinner than serrate part 10b after grinding.Simultaneously, the thickness of serrate part 10b increases towards top continuity ground.Two flanks by 23 grindings in taper position of emery wheel are that continuity ground is outward-dipping.As figure two findings, the width of steel bar 10 (highly) is in the diameter range of emery wheel 16,17, so that does not have the part 10a of sawtooth, by head-to-foot all be to be exposed between two parallel emery wheel working faces to accept grinding, and have only the serrate local grinding of inclination of accepting in top.
After the side of steel bar was polished, the chamfering 24 and 25 of each sawtooth 13 was just formed by grinding machine 15 grindings.Each chamfering 24 becomes 45 to spend with 25 with the plate face of steel bar.Yet chamfering 24 on one side is bigger than the chamfering 25 of another side.For the sawtooth of two vicinities, bigger chamfering 24 forms in two opposite directions, and shown as figure three and figure four, this makes when sawing, and the chip displacement of being more convenient for being cut simultaneously, except that having improved cutting efficiency, has more been strengthened the accuracy of direction.
The suitable especially a large amount of promptly extensive saw blades of making of producing of this neoteric method.If rectangular 10 materials of homogeneous not necessarily, it can be bimetallic, and wherein have sawtooth partly the material of 10b and no sawtooth part 10a be different.
