Abstract
The utility model discloses a band saw blade. A radiating punch hole for weakening welding thermal stress inside a band base section is at least arranged at the position, near a welding structure, on the band base section of the band saw blade. The thermal stress generated inside the band base section in a welding process of a grinding layer can be weakened by the radiating punch hole when the band saw blade disclosed by the utility model is produced; the radiating punch hole also can radiate heat generated by the cutting machining, and reduce vibration of the band base section in a using process. Thus, the machining precision of the band saw blade disclosed by the utility model is improved; the service life of the band saw blade is prolonged.
Description
Technical field
The utility model relates to a kind of band saw blade.
Background technology
The band saw blade used at present consists of with the tooth base section with a plurality of sawtooth banded base portion, and banded base portion and tooth base section are all the metal materials that adopt, and during in use band saw blade carries out the process of cutting continuously on cut workpiece, band saw blade can be because of the bad problem that hardness descends that produces of dispelling the heat, thereby cause the sawtooth sharpness of band saw blade and wearability to reduce, descend to the service life of whole band saw blade.
Notification number is the disclosed a kind of cutting saw blade based on carbide alloy of the Chinese utility model patent of CN201833076U, this cutting saw blade comprises banded base portion and has the tooth base section of a plurality of sawtooth, each sawtooth in tooth base section is the carbide alloy sawtooth of equidistant welding-on on banded base portion, and be coated with the grinding layer of being made by superhard material on this carbide alloy sawtooth, so that grinding layer is welded on banded base portion by the carbide alloy sawtooth, and pass through sharpness and the wearability that this grinding layer increases sawtooth, and extend the service life of whole saw blade.But on banded base portion in the process of seting welding carbide sawtooth, welding heat can be trapped on the banded base portion of saw blade, make the banded base portion of saw blade under the impact of thermal stress, produce distortion, the cutting accuracy of saw blade descends, the reduction in service life and the distortion on banded base portion can cause, thereby makes the service behaviour of whole saw blade descend.
The utility model content
The purpose of this utility model is to provide a kind of band saw blade that slackens thermal stress in banded base portion.
In order to realize above purpose, the technical scheme of band saw blade of the present utility model is as follows:
A kind of band saw blade, comprise banded base portion and at least two sawtooth, in each sawtooth, the surface of at least one is provided with grinding layer, between described grinding layer and sawtooth and/or between sawtooth and banded base portion, be provided with Welding Structure, to being less than near described welded position, offer be used to slackening the heat radiation perforation of sweating heat stress in banded base portion on described banded base portion.
On described each sawtooth, all be welded with described grinding layer, described heat radiation perforation on banded base portion along its length uniformly at intervals.
Described grinding layer is welded on the surface of sawtooth, and described sawtooth is fixed or one is connected on banded base portion.
Described grinding layer is wrapped on the surface of sawtooth.
Described banded base portion is end to end annular belt body, and described each sawtooth is on an end ring end face of banded base portion.
The utility model offers the heat radiation perforation to being less than described grinding layer relative position place on banded base portion, when producing band saw blade of the present utility model, this heat radiation perforation can slacken the thermal stress produced in banded base portion in the grinding layer welding process, and in use, this heat radiation perforation can also be distributed the heat that cutting processing produces, the vibrations that reduce banded base portion, thereby extend the machining accuracy of band saw blade of the present utility model, and extend the service life of band saw blade.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model.
The specific embodiment
The embodiment of band saw blade of the present utility model: as shown in Figure 1, this band saw blade comprises the tooth base section 2 arranged on circular banded base portion 1 and banded base portion 1 one end ring end faces, in tooth base section 2, be provided with circumferential uniformly at intervals the sawtooth 3 of a circle along banded base portion 1, the equal one of the tooth root of each sawtooth 3 is connected on banded base portion 1, and be welded with by superhard material and make on each sawtooth 3, and be wrapped in the lip-deep grinding layer 4 of sawtooth 3, and on the side face of banded base portion 1, offer a circle along its circumferential louvre 5 uniformly at intervals, the relative distribution of grinding layer 4 on each louvre 5 and each banded base portion 1.
Louvre 5 in the present embodiment is the small and dense circular hole along the circumferential distribution of banded base portion 1; and the banded base portion 1 on band saw blade and tooth base section 2 adopt common iron or hardened steel to process, and grinding layer 4 is the high-frequency welding under vacuum brazing or inert atmosphere protection at the lip-deep welding manner of sawtooth 3.
In the above-described embodiments, banded base portion is annular belt body, and in other embodiments, banded base portion can be also the belt body of strip.
In the above-described embodiments, grinding layer is wrapped on the surface of sawtooth, so that grinding all can be cut to workpiece in each side of sawtooth, in other embodiments, on the position that described grinding layer also can only be arranged on sawtooth with workpiece contacts.
In the above-described embodiments, be equipped with grinding layer on each sawtooth, in other embodiments, also grinding layer can only be set on part in each sawtooth.
In the above-described embodiments, grinding layer is welded on serrated surface, by sawtooth, to be welded on banded base portion, in other embodiments, grinding layer also can be by being coated on serrated surface, and sawtooth is welded on banded base portion, so that grinding layer is welded on banded base portion by sawtooth.
Claims (5)
