Abstract
The utility model discloses an arc-shaped planing blade, which comprises a metal blade body. A concave arc surface is arranged on a knife edge of the metal blade body, and is used for guiding outer burs after a machined product is planed, thereby avoiding the surface of the machined product being scratched by the outer burs. The circular arc of the concave arc surface has a radian value R of 8 to 20mm and a depth value H of 0.5 to 1.5mm, and the end of the concave arc surface has a root value B of 0.5 to 1mm. According to the arc-shaped planing blade, the problem that the surface of the machined product is directly scratched after the outer burs are upwarped due to the deficiency of annular guide of a straight blade is solved, and the product grinding cost caused by scratches is greatly lowered; the service life of the blade is greatly prolonged, and the wastage cost of the blade is saved; and the blade is not required to be secondarily manually ground, so that working hours are reduced, and the working efficiency is improved.
Description
Technical field
The utility model relates to and is applicable to high-frequency welding steel outer surface is processed and steel plate or steel band are carried out the blade of adverse slope mouth, refers to particularly a kind of arc planing blade.
Background technology
When being carried out that outer surface is processed and steel plate or steel band carried out the adverse slope mouth, the steel after the high-frequency welding need to use the planing blade.At present, the main planing blade that adopts is the straight blade of standard, as shown in Figure 1, straight blade in use, its steel edge lamellar body 1 is inserted in the mounting groove 6, then be welded on the blade harrow 5 with electric welding, after welding is good, blade harrow 5 is fixed on the knife rest 7 product to be processed 3 is planed, its outer burr 4 that produces is attached to product to be processed 3 surfaces, and there is following defective in this straight blade: one, because straight blade is without arcuate guide, it is rear directly with the product to be processed surface tear to cause outer burr to be rolled during planing, thereby affects the quality of product; Its two, if in use straight blade is carried out the artificial reconditioning of secondary, its hardness can change, greatly reduce service life, not only greatly improved cost, and the arc size of artificial grinding is nonstandard, is difficult to reach requirement.
Summary of the invention
The purpose of this utility model be exactly to provide a kind of simple in structure, durable in use, can make outer burr after planing, can derive smoothly and not scratch the arc planing blade of product to be processed.
For achieving the above object, the arc planing blade that the utility model is designed, comprise the steel edge lamellar body, be provided with concaved circular cambered surface above the edge of a knife of described steel edge lamellar body, described concaved circular cambered surface is used for the outer burr after the product to be processed planing is derived, thereby avoids the surface of product to be processed to be scratched by outer burr.
Further, the circular arc radian value R=8 ~ 20mm of described concaved circular cambered surface.
Further, the circular arc depth value H=0.5 ~ 1.5mm of described concaved circular cambered surface.
Again further, root B=0.5 ~ 1mm is stayed in the termination of described concaved circular cambered surface.
Like this, can go out according to the Thickness Design of different product to be processed the suitable cambered blade of standard, to reach production requirement.
Compared with prior art, the utility model has the advantage of: it is rear directly with product to be processed surface tear problem because cause outer burr to be rolled without arcuate guide that designed arc planing blade has solved straight blade, and the reconditioning expense of the product to be processed that causes because of scuffing reduces greatly; Greatly improve blade life, saved the blade cost depletions; Carry out the artificial reconditioning of secondary because need not blade, so saved man-hour, improved operating efficiency.
Description of drawings
Fig. 1 is structure and the working state schematic representation of existing straight blade.
Fig. 2 is the structural representation of the utility model arc planing blade.
Fig. 3 is the working state schematic representation of arc planing blade shown in Figure 2.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Be illustrated in figure 1 as structure and the duty of existing straight blade, in background technology, done detailed introduction, repeat no more therewith.
Shown in Fig. 2 ~ 3, arc planing blade of the present utility model, comprise for the steel edge lamellar body 1 of the outer burr 4 of planing, be provided with concaved circular cambered surface 2 on the edge of a knife of steel edge lamellar body 1, be provided with mounting groove 6 on the blade harrow 5, in use, steel edge lamellar body 1 is inserted in the mounting groove 6, then is welded on the blade harrow 5 with electric welding, after welding is good, blade harrow 5 is fixed on the knife rest 7 product to be processed 3 is planed, the outer burr 4 that planing is fallen is derived from concaved circular cambered surface 2.Because the each product to be processed of planing 3 differences, so the scope that the scope of the circular arc radian value R of concaved circular cambered surface 2 is designed to 8 ~ 20mm, circular arc depth value H is designed to 0.5 ~ 1.5mm, the termination stays the scope of root B to be designed to 0.5 ~ 1mm, like this, just can go out according to the Thickness Design of different product to be processed 3 the suitable cambered blade of standard, to reach production requirement, avoided carrying out the artificial reconditioning of secondary because of off size suitable blade, saved man-hour, greatly improved efficient
Operation principle of the present utility model is such: when planing, utilize the arcuate guide of concaved circular cambered surface 2, the outer burr 4 after successfully will planing is derived, thereby avoids product to be processed 3 surfaces to be scratched.
Claims (5)
