Abstract
The utility model relates to a steel saw blade with double-side teeth, which is a steel saw blade with saw teeth on sides and belongs to a hand tool for bench workers of tool hardware class. The steel saw blade with double-side teeth enhances the service life of a saw blade and enlarges the range of use of the saw blade by changing the structure of the existing saw blade. The steel saw blade with double-side teeth is characterized in that the both sides of the saw blade can saw, and therefore, the service life is long. The steel saw blade with double-side teeth of which the thickness is different can saw materials with different hardness and workpieces with different thickness. The utility model can be used in any ranges of use of the existing saw blades and can prolong the service life.
Description
The utility model belongs to the manual tool of instrument five metals class.
At present, the structure of known hand hack saw blade is: saw blade has only one side that sawtooth is arranged; When the sawing workpiece, saw blade often causes saw blade to scrap because of sawtooth blunt (or sawtooth collapses broken), and different material and the workpiece of sawing, needs the saw blade of several different thicknesses sawtooth.
Task of the present utility model is: by changing the structure of existing hand hack saw blade, the service life of improving saw blade, the scope of application of expansion saw blade.
Feature of the present utility model is: all there is sawtooth (seeing accompanying drawing) on the two sides of saw blade.Its structure is as follows:
(1) sawtooth angle: 40 ° of relief angles, 50 ° of the angles of wedge, 0 ° of anterior angle.
(2) saw blade thickness: saw blade two sides sawtooth thickness can consistent (seeing accompanying drawing 1), and the sawtooth thickness also can inconsistent (seeing accompanying drawing 2), and multiple combination is arranged.
(3) saw blade swage set: the width of saw blade two sides sawtooth swage set should be consistent with shape.
(4) sawtooth is arranged: the orientation of saw blade two sides sawtooth crown opposite (seeing accompanying drawing), and to reduce back side sawtooth when the sawing and the friction of workpiece.
(5) specification and series: specifications such as the length of saw blade, thickness are consistent with the specification and the series of existing saw blade.
The production method basically identical of production method of the present utility model and existing saw blade, different is when processing sawtooth and swage set, the two sides of saw blade all must be processed sawtooth, makes the two sides sawtooth that swage set all be arranged.
The utility model can be used for all scopes of existing hand hack saw blade, and it is rational in infrastructure, and long service life and scope are wide.
Shown in the drawings is the structure of two kinds 300 millimeters double cog hacksaw blade, and accompanying drawing has adopted the simplified painting of slender body, disconnects with double dot dash line in the middle of the saw blade, and its physical length is 300 millimeters.
Saw blade two sides sawtooth number shown in the accompanying drawing 1 all is a 14/25(/ millimeter), when sawing, after its sawtooth wearing and tearing (or sawtooth collapses broken), the another side of saw blade can continue to use.The saw blade of this identical thickness sawtooth in class two sides is mainly used in the bigger occasion of sawing amount.
The serration face sawtooth of the saw blade shown in the accompanying drawing 2 is a 24/25(/ millimeter), the sawtooth number of bastard face is a 14/25(/ millimeter); When the general workpiece of sawing, use the bastard face of saw blade, when sawing hard material or thin slice workpiece, carry out sawing with the serration face of saw blade.The saw blade of this class two sides different thicknesses sawtooth is mainly used in the occasion that the sawing amount is less or the sawing situation is various.
Claims (3)
1, hand hack saw blade, feature of the present utility model is: all there is sawtooth on the two sides of saw blade.
2, saw blade as claimed in claim 1 is characterized in that: the two sides sawtooth of saw blade can different thicknesses.
3, saw blade as claimed in claim 1 is characterized in that: the two sides sawtooth crown direction of saw blade is opposite.
