Description

Gardening scissors blade manufacturing method

The invention relates to a method for manufacturing a blade, especially a method for manufacturing a gardening scissors blade that can simplify the processing steps.

According to the conventionally known method of manufacturing a cutting blade, it provides a rough blank of a cutting blade made by a metal forming process such as stamping or forging, the cutting blade is an integrally formed long piece body, and the cutting blade has a serial connection A knife handle, a knife belly and a main knife portion, the knife handle is integrally connected to the knife belly and has a narrower width than the knife belly, and the knife handle is used for being installed on a scissors grip, and a shaft runs through the knife belly Hole, and the shaft hole provides the pivotal connection of the two cutting edges, the main blade portion extends from the blade belly in a direction opposite to the shank, and narrows to a tapered shape from the width, and the main blade portion is cut according to The usage habits and working parts can be divided into a blade back, a blade surface and a blade. Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: Heat treatment to increase the hardness of the material of the cutting edge, then place the cutting edge on the jig and grind the blade, and after grinding, fix the cutting edge to the jig in different directions, and then grind the blade surface to let The blade and the blade surface can form sufficient sharpness, because the grinding of the two sides of the blade and the blade surface needs to be fixed manually, and the grinding of the two sides also takes time and labor, and the structural strength of the thin blade and the blade surface is insufficient It is easy to deform or break during grinding, which leads to an increase in the defect rate. Therefore, the conventional manufacturing method has a defect that the production cost is too high.

In view of this, the inventor has many years of experience in manufacturing development and design of related products. With regard to the above objectives, after detailed design and careful evaluation, the invention finally has a practical application.

The technical problem to be solved by the present invention is to provide a method for manufacturing a garden shear blade in view of the above-mentioned defects in the prior art.

It includes: a blanking step, preparing the plate to be processed, and punching and cutting the plate with a cutting die to form a blade plate, and the blade plate has a first surface and a second Surface, a shaping step, the blade plate is placed in a shaping mold, and the shaping plate is used to stamp the blade plate, so that the first surface of the blade plate is shaped with a blade, a heat treatment step, The blade plate is subjected to surface heat treatment. In a blade grinding step, the second surface of the blade plate is partially ground with a grinding tool, thereby forming a gardening scissors blade with a sharp blade in cooperation with the blade.

Wherein, the gardening shear blade has a shaft hole and a handle plate for shaping the first surface during the shaping step, and the shaft hole is used for pivotally connecting two garden shear blades, and the handle plate is used for assembling a hand-held grip .

Among them, the garden shear blade is suitable for a one-handed operation garden shear.

Among them, the garden shear blade is suitable for a two-handed garden shear.

The first main object of the present invention is that in the blanking step, the sheet is continuously punched and cut with a cutting die, thereby quickly obtaining the blade plate, and then placing the blade plate after cutting into the shaping The mold performs the reshaping step so that the edge of the first surface of the blade plate is formed with the blade edge, and the heat treatment step is performed on the blade plate to harden the first surface and the second surface of the blade plate, and finally In the blade grinding step, the second surface is locally finely ground by the grinding tool, so that the corresponding edge of the second surface at the blade edge can be ground to form a sharp blade, because the gardening scissors are passed through the heat treatment step before grinding The blade has sufficient hardness, and a plurality of protrusions are formed on the blade through the shaping step, thereby improving the structural strength of the blade, that is, maintaining the stability and sharpness of the surface during grinding, thereby greatly simplifying In the case of processing steps, the production of suitable garden shear blades has the effect of reducing production costs.

Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description and related drawings.
