Description of the invention () (Please read the note r on the back before filling this page) The present invention is related to the processing of saw blades for cutting tools, especially about a rotary hole saw blade with a relatively simple process. Production method. The appendix is the Chinese Patent No. 388730, which provides a method for manufacturing a rotary saw blade, which roughly includes the following steps: 5-cutting: first cut a plate into a rectangular substrate (as shown in the third figure) No. 20), the substrate is a rectangular long side with a circumferential length of a preset saw blade (No. 20 in the sixth figure), and a rectangular width with an axis length of the preset saw blade; The long rectangular substrate is punched out by a stamping machine to produce the sawtooth (23), the fitting tenon (21) and the through hole (22) (as shown in the fourth figure); 10 3. Curling; the fourth icon number (20) The base plate is bent and clamped on a round rod mold with the same inner diameter as the preset saw blade, and is formed into a cylindrical shape with a gap, and the short sides of the rectangle are connected; 4. Welding: the fifth icon number ( 20) The two rectangular short sides of the substrate are welded together to form a complete cylindrical saw blade (sixth icon number 20); 15 V. Heat treatment processing ·· Finally, the formed saw blade is sent to a heat treatment machine for processing Heat treatment to complete the final material strengthening work. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, but the manufacturing method of the conventional rotary hole saw blade has the following disadvantages: After completing the first cutting step, the long rectangular substrates must be stamped. Only one piece of the long rectangle is placed on the stamping machine 20 at a time, and it is first positioned by the fixing member, and then the stamping process is performed. Then, the fixing member is loosened, the long rectangle after punching is removed, and then another piece is replaced. Long rectangle, repeat the aforementioned actions for punching; such a procedure is too tedious to reduce the production man-hours per unit of finished product, that is, the capacity cannot be effectively increased. -3- This paper size is in accordance with Chinese National Standard (CNS) A4 specification (210X297 mm) 528632 A7 B7 V. Description of the invention () (Please read the notes on the back before filling in this page) The main purpose of this invention is to Provided is a method for manufacturing a rotary saw blade, which has a high manufacturing process efficiency and can reduce the average production man-hour of a single finished product. In order to achieve the purpose of the previous disclosure, the manufacturing method of the rotary hole saw blade provided by the present invention includes the following steps: 1. Material preparation step: preparing a long rectangular plate of a predetermined size, the plate is preset The axial length of the saw blade is a rectangular short side. 2. The stamping step: The sheet is continuously input into a stamping machine, and the stamping machine is pressed one by one, so that one edge of the blade has 10 saws and the other edge has A plurality of mating grooves distributed in equal intervals to form a long mother piece; 3. Cutting step: cutting the mother piece into pieces of a predetermined size along the length direction one by one; 4. Setting steps: Each of the substrates is shaped into a cylindrical saw blade, and the two rectangular short sides of each of the saw blades are aligned. A preferred embodiment will be described in detail with reference to the drawings, wherein: The first diagram is a plan view of a plate before processing of a preferred embodiment of the present invention, printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The second figure is a plan view of the mother plate after the stamping step is completed in a preferred embodiment of the present invention; the third figure is a plan view of the mother plate of the second figure after being cut into a plurality of substrates, and the fourth figure is the third figure Saw blade formed after the substrate is shaped. -4- The paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm) 528632 A7 B7 V. Description of the invention () Perspective view; The fifth figure is the fourth figure The assembly diagram of the saw blade and the connecting member; and the sixth figure is a perspective view of the saw blade after the welding step in the fourth figure. 5 As shown in the figure, the manufacturing method of the rotary hole saw blade provided by this preferred embodiment is as follows: Step 1: As shown in the first figure, prepare a long rectangular plate (20) of a predetermined size, the plate The slice (20) is a rectangular short side with the axis length of the preset saw blade (10) (fourth figure). In practice, the plate (20) can have a considerable length, and can be wound into a round bundle of a smaller volume. Step 2: A stamping machine (not shown in the figure) with a predetermined number and position of the sawtooth mold, the fitting groove mold and the through-hole mold corresponding to the rotary hole saw blade (10), and the plate (20) is appropriately adjusted. The speed is subjected to continuous punching through the punching machine, and the plate (20) is punched into a mother piece (70) with a predetermined number and position of saws 15 teeth (30), fitting grooves (40) and through holes (50), such as As shown in the second figure. Step 3: Using a cutting machine, the mother film (70) that passes continuously is equally divided into several substrates (80) of the same shape. As shown in the third figure, the length of the rectangular long side of each substrate (80) is Preset the circumference of the saw blade (10) (fourth picture). 20 Step 4: Roll each of the substrates (80) into a cylindrical saw blade (10) with a setting machine roller, and make the two rectangular short sides of each of the saw blades (10) roughly correspond. In practice, in step 3, the substrates (80) with different rectangular long side lengths can also be cut as required. In this way, the rolls are rolled into saw blades (10) with different diameters. After the above four steps, the saw blade (10) has two rectangular short sides. Since this paper size is not applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the note I on the back side before filling) *: Write this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 528632 A7 B7 V. Description of the invention () It is fixed, so it will have considerable flexibility, so that it can be slightly increased or reduced in diameter to facilitate Installed and fixed in the connecting piece (90) with possible tolerances (91) (fifth figure), and linked with the power mechanism (not shown), so that the saw blade (10) can be used to cut specific Round hole with aperture. 5 Of course, the formed saw blade (10) can still be processed by heat treatment, painting, electroplating (not shown) to enhance the texture or beautify the appearance. To sum up, since the present invention first applies a stamping process to the sheet material (20), it can perform a continuous process of continuous stamping, cutting, and shaping, that is, to complete multiple saw blades (10) in one breath, compared with In the foregoing conventional manufacturing method, the material plate is first cut into multiple long rectangles, and then the single-piece long rectangle is positioned, stamped, and replaced. The iterative processing procedure obviously has the advantage of improving the process efficiency, and makes the single The average production man-hour of the finished product is effectively reduced, and the production capacity is relatively increased. In addition, in practice, it is also possible to set the saw blade (10) with a fixed diameter. Please refer to the sixth figure of 15 for details. After step 4, the rectangular short side of the saw blade (10) is welded to form a weld. Thread (60) (it can also be ground and polished). --------- ^ — (Please read the precautions of Back® before filling out this page) Order 4 This paper is printed by the Intellectual Property Bureau Staff Consumer Cooperative of the Ministry of Economic Affairs, and the paper size applies to the Chinese National Standard (CNS) A4 specification ( 210X297 mm) 528632 A7 B7 V.
