Abstract
The invention provides a special-shape pruning blade and a processing method thereof. The blade is provided with cutting teeth which extend toward the outside and are arranged in the shape of comb teeth; two ends of the section of the blade in the extension direction of the cutting teeth are thick, and the middle part of the section of the blade is thin; and further, the section is provided with an arc edge in the direction of the cutting teeth. The processing method of the special-shape pruning blade comprises the following steps of: firstly arranging a thin narrow gasket on a grinder sucking disc, then flatly arranging the blade on the gasket and arranging the gasket in the middle of the blade approximately, and grinding the plane of the blade. Gags on an upper blade and a lower blade of a special-shape pruning blade assembly, and especially a gap between the cutting areas of the blades are eliminated, thus the cutting quality and efficiency are improved; and the processing method of the blade is simple.
Description
Technical field
The present invention relates to a kind of pruner blade and processing method thereof, belong to garden kind tool manufacturing field in the electric tool.
Background technology
Pruner is field, a gardens cutting implement commonly used, can prune and repairs for shrub, hedge etc., the pruning tool head set of blades that blade is up and down formed of serving as reasons; Blade is elongated; The reciprocal relative motion of last bottom knife through along its length, thus the cutting teeth that drives the broach shape that is provided with along its width is realized the pruning to branch etc., and the gap length on the pruning set of blades between the bottom knife directly influences cutting efficiency and cut quality; Especially need heat treated blade after the punching press; Because existence such as heat treatment deformation, grinding deformation can make blade to the grinding face buckling deformation after the grinding, make that the gap between two blades is bigger.
Summary of the invention
Defective to above-mentioned prior art existence; The present invention provides a kind of pruning blade and processing method thereof of special shape, through the simple machining process method, realizes the thickness of control blade different parts; Reach cutting zone gap, blade assembling back and reduce, improve the operating efficiency of blade.
For realizing above technical purpose, the present invention adopts following technical scheme:
A kind of pruning blade of special shape; Blade has the cutting teeth of the broach shape setting of extending laterally; The section thickness of said blade on the cutting teeth bearing of trend is that thick middle part, two ends is thin; Said cross section is along having an arc limit on the cutting teeth direction, said blade simultaneously is the plane, and another side is the arcuation face.
A kind of pruner comprises tool heads, and tool heads is the set of blades of being made up of upper and lower blade; Blade is elongated; Upper and lower blade passes through reciprocal relative motion along its length, drives along the cutting teeth of the outward extending broach shape setting of its width and realizes the pruning to branch, and the composition surface of said upper and lower blade is the plane; The another side of relative bonding face is the arcuation face, and said arcuation face makes thick middle part, blade thickness two ends on width thin.
A kind of processing method of making above-mentioned pruning blade comprises the steps:
At first on grinder chuck, put a thin narrow pad;
Be placed on blade planar on the pad then, and make pad roughly place the blade medium position;
Grinding is carried out on the blade plane.
Through adopting above technical scheme, can realize following useful technique effect:
1, eliminate the upper and lower blade of pruning set of blades, especially cut quality and efficient are improved in the gap in blade cuts zone;
2, the blade processing technology is simple.

Embodiment
Do explanation in further detail below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1, shown in Figure 2, be the sketch map of the pruning blade of special shape of the present invention, the shape of the blade of the shape of blade and prior art is similar among Fig. 1, and blade is elongated, and the both sides of blade have the cutting teeth 6,6 that the broach shape that extends laterally is provided with
,, wherein, blade one side cutting teeth 6 is a sharp mouth, has sharp cutting edge 7 on the sharp mouth, blade opposite side cutting teeth 6
,Be cognate; Also be provided with pilot hole 8 on the blade; Fig. 2 is a section A-A shape sketch map on this pruning blade broad ways D (blade width direction D is consistent with the direction that cutting teeth extends), and pruning blade as can be seen from Figure 2 of the present invention is different with blade of the prior art, and existing pruning blade thickness is a uniformity; The two sides of blade all is plane 11; Pruning blade of the present invention simultaneously is plane 11, and another side is arcuation face 12, thereby makes this section A-A be the thin shape in thick middle part, the two ends with an arc limit.
As shown in Figure 3, be tool heads 20 sketch mapes of pruner of the present invention, tool heads 20 is by upper and lower blade 1,1
,The set of blades of forming can be known blade 1,1 in conjunction with Fig. 1, Fig. 2 and Fig. 7
,Elongated, upper and lower blade 1,1
,Through the reciprocal relative motion of C along its length, drive the cutting teeth 6,6 that is provided with along the outward extending broach shape of its width D
,Interlaced realization is to the pruning of branch etc., and wherein, blade one side cutting teeth 6 is a sharp mouth, has sharp cutting edge 7 on the sharp mouth, blade opposite side cutting teeth 6
,Be cognate, upper and lower blade 1,1
,On be respectively arranged with pilot hole 8, and the bolt through passing pilot hole 89 fixes with nut, bolt 9 can move in pilot hole 8, the upper and lower blade 1,1 after the assembling
,The composition surface be plane 11,11
,, the another side of relative bonding face is arcuation face 12,12
,, said arcuation face 12,12
,It is thin to make blade thickness on width D, be thick middle part, two ends.
The sketch map of Fig. 4 in the prior art pruning blade simultaneously being carried out grinding; Fig. 5 carries out grinding for the present invention to the one side of pruning blade sketch map; Can know in conjunction with Fig. 4, Fig. 5; The present invention is before carrying out grinding to the one side of pruning blade 1; Between blade 1 and grinding machine 3 suckers, be provided with a thin narrow pad 2, this thin narrow pad 2 roughly places the medium position (this medium position be meant along on the blade width direction D) of pruning blade 1, place among the figure blade 1 top for being used for the emery wheel 10 of grinding.
Fig. 6 is the sketch map that pruning knife sheet assembling of the prior art back cooperates, the sketch map that Fig. 7 cooperates after assembling for pruning blade of the present invention, upper and lower blade 1,1 among Fig. 6
,The cutting edge of cutting teeth zone 5 forms big gap, upper and lower blade 1,1 among Fig. 7 in both sides
,The gap that the assembling back forms has been eliminated in the cutting edge of cutting teeth zone 4 in both sides, can know that in conjunction with Fig. 6 and Fig. 7 pruning blade of the present invention can improve cut quality and efficient.
The processing method of the pruning blade of special shape of the present invention comprises the steps;
At first on grinder chuck, put a thin narrow pad;
Be placed on blade planar on the pad then, and make pad roughly place the medium position on the blade width direction;
Grinding is carried out on the blade plane.
Because the blade middle part is by bed hedgehopping; Blade behind the grinding plane is the thin shape in thick middle part, two ends; Can effectively correct the situation of the blade buckling deformation that exists in the prior art, thereby, if two blade assembling backs just can realize that blade cutting edge cutting zone fit clearance is little.
In the processing method of the present invention, place blade and also can exchange with the step of placing pad, such as:
At first be placed on blade planar on grinder chuck; Between blade and grinder chuck, fill in a thin narrow pad then, and make pad roughly place the medium position on the blade width direction; Grinding is carried out on the blade plane.
