Abstract
The utility model relates to the field of wood cutting processing and in particular relates to a machine clamping type woodworking trimming knife with helical cutting edges. The machine clamping type woodworking trimming knife comprises a knife body, wherein a plurality of helical grooves are formed in the knife body in a surrounding manner and are arranged at intervals; the knife body between two adjacent helical grooves forms a helical blade mounting part; a plurality of blades are arranged on the blade mounting parts at intervals; the blades are detachably connected with the blade mounting parts. The blades of the knife are a plurality of detachable blades; during cutting processing of the knife, when a certain blade is damaged or abraded excessively, the damaged or excessively abraded blade can be replaced directly instead of replacing the overall knife; therefore, the use cost of the knife is saved, and the knife is easy and convenient to replace; the knife can adapt to large-scale processing and production.
Description
Technical field
The utility model relates to wood cutting manufacture field, particularly a kind of clip type woodwork spiral sword knife tool.
Background technology
Along with developing rapidly of wood-processing industry and furniture manufacturing industry, advance to wood cutter, practicality and the accuracy of manufacture require also more and more higher, traditional welding formula wood cutter, its blade is to make with carbide alloy or other wear resistant cutters materials, and a plurality of blades are welded on cutter hub, although be connected firmly between blade and cutter hub, but be difficult for changing after its blade abrasion or damage, so, in order to guarantee that cutter can adapt to the needs of large-scale processing, extend the service time of cutter, avoid the waste of cutter, normally after the most of wearing and tearing of blade just by cutter integral replacing, adopt in this way, although can realize large-scale processing, but because the blade of cutter is not changed in time when there are wearing and tearing, so that adopt the timber of this tool sharpening usually to occur timber roughness of machining surface, deckle-edged situation, and then can not complete the retrofit of product.
In addition, in the process of timber processing, the degree of wear of each blade is inconsistent, causes timber to add man-hour, and the machined surface quality disunity of each blade has further reduced the precision of tool sharpening timber.
So, to need badly at present and a kind ofly can be convenient for changing blade, assembly manipulation is simple, applicable to the wood cutter of extensive retrofit.
Utility model content
The purpose of this utility model is: the blade existing for existing welded type wood cutter is difficult for changing, be not suitable for the deficiency of extensive retrofit, provide a kind of and can be convenient for changing blade, dismounting is simple, is applicable to the clip type woodwork spiral sword knife tool of extensive retrofit product.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of clip type woodwork spiral sword knife tool, include cutter hub, on described cutter hub, be surrounded with a plurality of helical grooves, described a plurality of helical grooves interval arranges, cutter hub between adjacent two helical grooves forms spiral helicine blade installation portion, on described blade installation portion, be arranged at intervals with some blades, described blade is detachable connection with described blade installation portion.The blade of cutter is set to several dismountable blades, when using cutter to carry out machining, when there is damage or excessive wear in indivedual blades, can directly change the blade of damage or excessive wear, and need not change whole cutter, when having saved cutter use cost, also make the replacing of cutter simple and convenient, and then make cutter can be adapted to large-scale processing and produce.
As preferably, described blade is the square blade with a plurality of blades.Blade possesses a plurality of blades simultaneously, when one blade damages or during excessive wear, can unclamp and rotating blade is further saved the use cost of cutter as cutting blade using one in other blades, has also saved the more time of allowing blade replacement.
As preferably, the blade on described adjacent two blade installation portions is around the setting of staggering of described cutter hub central axis hoop.In when cutting, blade is around the cutter hub central axis rotary face of cylinder in aggregates, prevents from occurring not being cut part on the machined surface of processed timber, and makes processed timber can obtain continuously being cut, and meets the demand of retrofit.
As preferably, described helical groove is dextrorotation, and its helical angle is 9 °～15 °.During machining, blade is progressively cut to workpiece, its contact-making surface is ascending, thereby, suffered cutting resistance smooth change, so, make working angles steady, avoided causing due to cutting resistance sudden change shock and the vibrations of cutter hub, effectively reduce cutting power and noise, improve the fineness of cutting surface, met the requirement of retrofit.
As preferably, on described blade installation portion corresponding to described blade, be provided with annular groove, described blade is arranged in described annular groove, and described annular groove and described helical groove are connected.When cutting, wood chip is cut by blade, enters annular groove, and then enters in helical groove from annular groove, has facilitated the discharge of wood chip, to reduce cutting resistance.
As preferably, described blade is connected by sunk screw with described cutter hub.With sunk screw, connect blade and cutter hub, make the installation and removal of blade and cutter hub convenient, also avoided screw to scratch processed timber.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, after tool wear, only need allowing blade replacement, retain cutter hub, easy and simple to handle, avoid waste;
2, be applicable to extensive timber processing, and process meticulous.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Mark in figure: 1-cutter hub, 2-helical groove, 3-blade installation portion, 4-blade, 5-annular groove, 6-sunk screw.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of clip type woodwork spiral sword knife tool as shown in Figure 1, include cutter hub 1, on described cutter hub 1, be surrounded with a plurality of helical grooves 2, described a plurality of helical groove 2 intervals arrange, cutter hub 1 between adjacent two helical grooves 2 forms spiral helicine blade installation portion 3, on described blade installation portion 3, be arranged at intervals with some blades 4, described blade 4 is detachable connection with described blade installation portion 3.The blade of cutter 4 is set to several dismountable blades 4, when using cutter to carry out machining, when there is damage or excessive wear in indivedual blades 4, can directly change the blade 4 of damage or excessive wear, and need not change whole cutter, when having saved cutter use cost, also make the replacing of cutter simple and convenient, and then make cutter can be adapted to large-scale processing and produce.
As preferably, described blade 4 is for having the square blade 4 of a plurality of blades.Blade 4 possesses a plurality of blades simultaneously, when one blade damages or during excessive wear, can unclamp and rotating blade 4 is further saved the use cost of cutter as cutting blade using one in other blades, has also saved the more time of allowing blade replacement 4.
