Abstract
The scraper having a blade edge 1a is formed at the end of a tabular main body 1 wherein the tip axis of blade 1a is made to have an angle of [theta]1 to the axis of the main body.
Description
Technical field
The present invention relates to a kind of scraping, thereby this scraping is a kind of being used for tiny thrust or adhesion to be eliminated the hand tools that smooth surface is provided from the outer surface of woodwork and so on.
Background technology
Usually, for the outer surface in the needs polishing, for example produce the minute surface coating with high smoothness on the outer rim of grand piano, the base material polishing before coating is very important, and its quality is influential to final coating.Especially for the outer rim of above-mentioned grand piano, because its appearance but curved surface, so in the time will implementing machine cut, might use the cutting edge of router (router).Yet it is very difficult implementing evenly processing automatically.In addition, because the size of object is big, therefore use sand-blasting machine possibly.But, be unpractical like this from the angle of installation cost, processing cost and environmental concerns.
In practice, because these problems make the polishing process of outer surface be carried out by hand by skilled carpenter specially usually.In this case, though can utilize plane to implement the polishing of plane surface, but be difficult to utilize plane that curved surface is polished.Therefore, use scraping that outer surface is carried out manual equating (as shown in Figure 3) traditionally, such as proposed a kind of scraping in Japanese utility model application publication No.61-53111, this scraping is made of plate shape main body and the cutting edge that is formed on this body distal end place.
In this scraping that conventionally uses, as shown in Figure 4, the tip direction of cutting edge 100a extends along the direction consistent with main body 100 in-planes (L1-L1 among Fig. 4).Thus,, make the tip of cutting edge 100a can not contact the finished surface of processing object W observantly, cause on finished surface, producing shallow bite mark owing to have the operating angle a that under the routine work attitude, forms.The result can not obtain enough cutting effects, especially increases the curved surface at the angle of inclination of cutting edge 100a for meeting.Cutting effect for the conventional scraping that strengthens such structure can use this scraping with the orientation of nearly erect.Yet use will destroy performance easy to use like this, and the result reduces operating efficiency.
Summary of the invention
Construct the present invention considering on the basis of above problem, the purpose of this invention is to provide a kind of scraping, the tip of this scraping cutting edge can be under natural user mode with the finished surface of desirable angle contact object to be processed, thereby not only for flat surfaces, also provide enough cutting effects for curved surface.
In order to overcome the above problems, according to the present invention, a kind of scraping, it is a kind of hand tools, and is made by steel plate materials; Described scraping comprises: plate shape main body, and this plate shape main body comprises a plurality of sides and the planar section parallel with first axle; And the cutting edge that is formed on the place, a side in a plurality of sides of described main body, wherein said cutting edge has tip portion, this tip portion has the central axis that tilts to described first axle, and can be used for tiny thrust or the adhesion outer surface from woodwork and so on is eliminated by described tip portion.
Preferably, in above scraping, the angle that central axis tilts to first axle is equal to or less than 90 degree.
By the description below in conjunction with accompanying drawing, above and other purpose of the present invention and feature will become obvious.
Description of drawings
Fig. 1 is the side view that first embodiment of the invention is shown;
Fig. 2 is the side view that second embodiment of the invention is shown;
Fig. 3 is the view of the usage of interpretation routine scraping; And
Fig. 4 is the side view that conventional scraping is shown.
The specific embodiment
Describe embodiments of the invention below with reference to the accompanying drawings in detail.
Fig. 1 is the side view according to the scraping of first embodiment of the invention, the main body that label 1 expression is made by steel plate materials.The same with conventional body, this main body is configured to basically: have plate shape shape, and grasped in its proximal end, and at its far-end the finished surface of processing object W is cut.Note that the far-end of main body to be made for to have the cutting edge 1a that oblique one side is pointed to, as shown in Figure 1 by machining etc.More particularly, the axis L 2-L2 of cutting edge 1a tip portion has the tiltangle 1 with respect to main body in-plane L1-L1, thereby cutting edge is directed in the finished surface place of processing object W.As a result, according to the scraping of constructing like this among first embodiment, by the operating angle a that forms under the operate as normal attitude, cutting edge contacts the finished surface of processing object W observantly along the cutting direction of processing object W, thereby can improve stock-removing efficiency.
Fig. 2 is the side view of the scraping finished according to second embodiment of the invention, the main body that label 1 expression is made by steel plate materials.The same with first embodiment, this main body is configured to basically: have plate shape shape, and grasped in its proximal end, and at its far-end to the processing table of processing object W and cut.Cutting edge 1a is formed on the far-end of main body 1, as shown in Figure 2.The axis L 2-L2 of cutting edge 1a tip portion has the tiltangle 1 with respect to main body 1 in-plane L1-L1.As a result, by the operating angle a that forms under the operate as normal attitude, stock-removing efficiency improves.
Preferred angled angle θ 1 is equal to or less than 90 degree.
Surpass under the situation of 90 degree at tiltangle 1, be difficult to scrape the finished surface of thorn processing object with the cutting edge of scraping.
As above described in detail, according to scraping of the present invention, because the central axis of cutting edge tip portion has the inclination angle with respect to the main body in-plane, so cutting edge can be worked effectively, even under the finished surface of processing object is the situation of curved surface, also can produce enough cutting effects thus, and can be processed to form outer surface with high smoothness.Because above content, can obtain significant effect, comprise that scraping does not make wrist bear operability under the natural posture of pressure.
Although below described and explained the preferred embodiments of the present invention, should be appreciated that these are example of the present invention, should not think restriction to it.Under the situation that does not depart from the spirit and scope of the invention, can increase, delete, replace it and other change.Thus, the present invention should not think the description that is subject to the front, and is just limited by the scope of claim.
