Abstract
The utility model discloses a kind of burring knife for injecting products, comprise plastic knife handle (1) and single dege blade (2), plastic knife handle (1) adopts impact resistant polystyrene to make, single dege blade (2) employing thickness is that the high carbon tool steel sheet material of 2-3mm is made, the body width of single dege blade (2) is consistent, the front end of single dege blade (2) is cut into hypotenuse, and whole hypotenuse is provided with the inclined plane that angle α is 20 ~ 45 °, thus constitute the blade (2a) of single dege blade (2); The tail end of single dege blade (2) from front to back width increases gradually, and the recruitment of the left and right sides is equal, thus forming a fishtail connecting portion (2b), fishtail connecting portion (2b) embeds in plastic knife handle (1).Long service life, easy to operate, can ensure that product surface is smooth during for removing injecting products burr and overlap.
Description
Technical field
The utility model belongs to cutting-tool engineering field, is specifically related to a kind of cutter for removing injecting products burr.
Background technology
Adopt the plastic product of injection mo(u)lding, some burrs and overlap can be remained down after shaping, affect the outward appearance of product, need it thoroughly to get rid of.The now current cutter for removing burr and overlap, the reused snap blade normally commercially bought.This blade is double-edged blade, and blade is thinner, can not vertically exert oneself during use, and after removing burr, product surface is rough; Blade is longer, inconvenient operation, causes production efficiency low; Although repeatedly use after broken, overall life is not long, and blade consumption is large, and use cost is high.
Utility model content
For above-mentioned technical problem, the utility model is intended providing a kind of long service life, the easy to operate cutter being exclusively used in removal injecting products burr and overlap, and can ensure that the product surface removing burr and overlap is smooth.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of burring knife for injecting products, comprise plastic knife handle (1) and single dege blade (2), key is: described plastic knife handle (1) adopts impact resistant polystyrene to make, single dege blade (2) employing thickness is that the high carbon tool steel sheet material of 2-3mm is made, the body width of described single dege blade (2) is consistent, the front end of single dege blade (2) is cut into hypotenuse, and whole hypotenuse is provided with the inclined plane that angle α is 20 ~ 45 °, thus constitute the blade (2a) of single dege blade (2), the tail end of described single dege blade (2) from front to back width increases gradually, and the recruitment of the left and right sides is equal, thus forming a fishtail connecting portion (2b), described fishtail connecting portion (2b) embeds in plastic knife handle (1).
Preferred as such scheme, the rear end of described blade (2a) stretches out, and the angle of extension is greater than the angle of blade (2a), forms a blunt portion (2c).Blunt portion is made up of the extension of end band mitre after blade, ensure that on the one hand the effective length of blade, on the other hand due to this position when gripping closer to operator, blunt portion is set and can avoids scratching hand.
In addition, the nose width of described fishtail connecting portion (2b) is less than the body width of single dege blade (2), and the rear end width of fishtail connecting portion (2b) is larger than the body width of single dege blade (2).Optimized dimensions, ensureing the prerequisite that fishtail connecting portion can not be deviate from plastic knife handle, saves material to greatest extent, reduces manufacturing cost.
Further, the middle part of described plastic knife handle (1) is provided with anti-skidding cut (1a), is convenient to grip, and prevents from skidding in use procedure.
Be preferably, the angle β of described single dege blade (2) front end hypotenuse is 60 °, and the angle α of described blade (2a) is 45 °.
The beneficial effects of the utility model are:
(1) blade adopts one side to be inclined-plane, and another side is the single dege blade of plane, in use procedure, can exert oneself perpendicular to product surface, avoids forming cut at product surface, improves the product quality of processing;
(2) plastic knife handle adopts impact resistant polystyrene to make, and single dege blade employing thickness is that the high carbon tool steel sheet material of 2-3mm is made, and improves cutting-tool's used life by selection;
(3) afterbody of single dege blade embeds in plastic knife handle, whole burring knife adopts insert structure, in plastic knife handle forming process, single dege blade directly embeds, and prevent single dege blade from deviating from from plastic knife handle in conjunction with fishtail connecting portion, solid and reliable, meanwhile, the width incremental change of the fishtail connecting portion left and right sides is equal, ensure that left and right stress balance, is the steadiness in order to improve installation equally;
(4) limit the angle α of blade, α crosses very much not sharp, and α is too small not wear-resisting, easily repaiies scarce.

Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Figure 1, a kind of burring knife for injecting products, is made up of plastic knife handle 1 and single dege blade 2 two parts.
Plastic knife handle 1 adopts impact resistant polystyrene (HIPS) to make, and single dege blade 2 adopts thickness to be that the high carbon tool steel sheet material of 2-3mm is made.Material, the thickness of single dege blade 2 all have requirement, and object improves the intensity of single dege blade 2.
The body width of single dege blade 2 is consistent, and the front end of single dege blade 2 is cut into hypotenuse, and whole hypotenuse is provided with the inclined plane (as shown in Figure 2) that angle α is 20 ~ 45 °, thus constitutes the blade 2a of single dege blade 2.Blade 2a one side is inclined-plane, and one side is plane, therefore is called single dege blade.
The tail end of single dege blade 2 from front to back width increases gradually, and the recruitment of the left and right sides is equal, thus forms a fishtail connecting portion 2b, fishtail connecting portion 2b and embed in plastic knife handle 1.In actual production process, the tail end of single dege blade 2, after high-temperature fusion, inserts in fused mass, then applies pressure, compressed by the tail end of single dege blade 2 by impact resistant polystyrene.
Shown in composition graphs 1-Fig. 3, preferably, the rear end of blade 2a stretches out, and the angle of extension is greater than the angle of blade 2a, forms a blunt portion 2c, and namely blunt portion is made up of the extension of end band mitre after blade.Be preferably, the angle β of single dege blade 2 front end hypotenuse is 60 °, and the angle α of blade 2a is 45 °.
In addition, the nose width of fishtail connecting portion 2b is less than the body width of single dege blade 2, and the rear end width of fishtail connecting portion 2b is larger than the body width of single dege blade 2.The middle part of plastic knife handle 1 is provided with anti-skidding cut 1a.
