Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a metal scraper that can extremely easily form a sharp scraper blade, and its structure is detailed as follows with reference to the accompanying drawings. .

Grooves 2 are formed at regular intervals on the back surface of a metal plate 1 by press working, and the grooves 2 are
A protruding strip corresponding to the recess of the concave strip 2 is formed on the surface of the plate material 1 where is located, and a cutting edge 3 protruding from the front side of the plate material 1 is formed in parallel on this protruding strip by press working. to form the cooking plate 4.

The formation of the grooved portion 2 and the formation of the unloading blade 3 may be performed at the same time, or the removal blade 3 may be formed after the grooved portion 2 is formed.
may be formed.

Further, even if the grooves 2 are not formed, if the spacing between the unloading blades 3 is large, the grooves may be formed at intervals corresponding to the spacing.

The cutting blades 3 in the drawings are triangular in shape, with their corners facing each other.

Recently, there are a lot of devices for removing radish, carrots, etc., but most of them are made of plastic and have an integrated cutting blade.

The reason for this is thought to be that it is easy to mold, can be mass-produced, and is available at a low price.However, on the other hand, the cutting blade wears out quickly and its sharpness decreases, and it also tends to discolor and get dirty easily. There were also flaws that impaired the quality of the product.

Metal blades do not have the above-mentioned disadvantages, but on the other hand, each blade is hammered out one by one with a chisel, which is extremely troublesome and cannot be mass-produced. There were flaws.

The present invention solves these drawbacks, and since it is constructed as described above, it is possible to form the cutting blade 3 with good sharpness by press working even though it is made of metal.

The reason is that the cutting edge 3 is formed by press working, which is extremely simple and can be mass-produced.

In this case, if the surface of the plate material 1 is simply press-worked, the degree of protrusion from the surface of the cutting edge 3 is small, so the cutting edge 3 will not be sharp and its cutting quality will be poor.

In this regard, the present invention, as shown in FIG.
Since the protruding stripe is formed by the concavity between the surface and the concave stripe 2, the dispensing blade 3 is formed higher by the amount of the protrusion, resulting in the dispensing blade 3 having good sharpness.

In addition, this bulging strip serves as reinforcement, and the structure inside the cutting blade 3 is also made airtight through press working, resulting in a durable cutting blade 3 that does not wear out, thereby providing a durable metal cutting blade 3 that does not deteriorate in sharpness. I will do it.

Furthermore, by using stainless steel for the plate material, it has an excellent feature that it does not rust and provides a sanitary and good-looking metal dispenser.

Claims (1)

[Claims] 1 Form grooves 2 at regular intervals on the back surface of a metal plate 1 by press working, and bulge lines corresponding to the recesses of the grooves 2 on the surface of the plate 1 where the grooves 2 are located. A method for producing a metal unloading device, characterized in that a cooking plate 4 is formed by forming a cooking plate 4 by forming a cutting blade 3 that projects on the front side of a plate material 1 in parallel on this bulging strip by press working.
