Description

^ ----- No. 91123167 V. Description of the invention (1) [The present invention, the present invention relates to a kind and in particular to a kind of process j ^ /, is made by using forging, turning and other surface processing steps It can be promoted by a real industry, and it is disclosed in [the ratchet wrench of the present invention, and research and creation as one of the first drawing m hand tools. There are many and all teeth have one. However, the influence of the periphery, due to the accuracy of the control number, means that it only shows more than 7 2 teeth, and the return of 7 2+ is back to 1 ′ The more the number of teeth is limited, the more important is to say that it is in the system (that is, the number of teeth is pure, “Cause 7 2 is not a system of a lot of operations. From the accuracy of the overall number of teeth, the process of the teeth is clear. Can be less than the essence of life until now there is no other, the number of teeth of the industry can be made in detail 90 ton torsion trimming body, to achieve the usefulness and background of the general public (1) can be shown, 'regardless of Is Ming

To the 180 value of the ratchet value of the tooth, and the grinding, tumble drying, and heat effect of the south ring, the invention of the step, which is the most ratchet wrench in the world (one-way action or two-wheel) The method of ratcheting system and processing, so when it is worthwhile to send the previous ratchet to the ground, the number of salaries exceeds the medium quality of 5 per tooth, which is still not because of this process, its ratchet 3 6 teeth straight hand (1 ) The synergy will be even more true. There is a spine slogan with an instability angle of 7 2 teeth. There are more than 9 kinds of south teeth.

(1 ') Until now, the structure is good, but it is also known as 7 2 (but this is the reason why it is toothed). The ratchet with 0 teeth is also fine because it is commonly used; Two teeth have the same number of teeth, and the number of teeth produces slightly more ratchets. (Can not be required ill. Page 4 592903 ΛΆ 9112λ1B7 V. Description of the invention (2) The inventor is based on the issue of the present invention. Consumers and the industry [the main purpose of the present invention is 0 to 180, the number of peripheral teeth of the present invention and the secondary mesh torque value and better meshability of the present invention is another object of the present invention to manufacture this method The system of the number of equal ratchet teeth can therefore be called quite a breakthrough. [The present invention is related to the method of making reference to the second figure, which mainly includes: 1. Forging: ie 10), as shown in the third figure 2. Fireballization Fireballization, the purpose is stability; and in the system, the best is two destructuring to have toughness, and make it have

After revising years of experience in manufacturing this type of product, it was finally developed to a 180-tooth ratcheting method. The purpose of the invention of the invention is to make the ratchet wheel have a 90-degree process; the system can make its ratchet wheel more The higher is because it can make 90 to 180 teeth simple and convenient, which is beneficial to the process of the manufacturer; the invention can be said to be quite progressive, and an invention, and has industrial use A detailed description of the embodiment of the value invention] As shown in a ratcheting method capable of producing 90 to 180 teeth, this ratchet capable of producing 90 to 180 teeth is firstly roughened by a forging technology (As shown; • That is, the ratchet body rough embryo (10) must be annealed and spheroidized again and again to eliminate its stress due to forging and strengthen its knotting process according to the accuracy of the number of teeth. From brittle to soft with better machinability to facilitate subsequent processing; mm 592903 case number 91123167

Amendment V. Description of the invention (3) Third, the lathe trimming the body: that is, the lathe fine embryo is reprocessed by turning, and the second fine embryo of the ratchet body is made (1 2); Fourth, the grinding process: That is, the secondary fine embryo (1 2) of the ratchet body after lathe processing is ground, and this step can be controlled to about 1 u to 5 u by intentional or unintentional grinding. And as shown in the fourth and fifth figures;

V. Rolling: The ratchet body fine embryo is positioned after the completion of the fourth step, and the internal buckle is rotated and chiplessly extruded to form a ratchet tooth (13) with a peripheral ratchet number of 90 to 18, which is mainly achieved by The precise control of the pressure value, the center point and the rotation speed can obtain ratchet teeth with 90 to 180 ratchet teeth; and as shown in the sixth figure; 6. Heat treatment: the ratchet teeth (13) are heat-treated to increase Its structural hardness; 7. Surface treatment: The ratchet tooth fine embryo is surface-treated (such as electroplating or blackening) to become a finished ratchet with 90-180 teeth (20 Of course, the present invention can also be used in the same manufacturing process , Can change the rolling process of the smelting tool can be made into concave tooth profile, convex tooth profile, double concave tooth profile and arc tooth profile ratchet structure, and as shown in Figures 8 to 11; After many experiments by the inventor, the present invention can indeed be made into ratchet teeth with high precision, and has the functions and advantages of high torque withstanding value and high meshability. The elaborate and ingenious design is amazing, and the invention is indeed practical and Industrial Utilization Value As can be widely promoted. 90 can thus be made to the teeth 180 of the ratchet wheel manufacturing method of the present invention can be

Your review is quite practical and has industrial use value. The inspectors can better understand the effect and value of the present invention. The above arguments are discussed: 1. The present invention can be made 90 to With the method of ratcheting with 18 teeth, the basin is mainly made of ratchets with the above-mentioned number of teeth through various steps, because of the high torque withstanding value and high meshability; 2. The present invention can produce 90 to 180 teeth. Ratcheting method, each step has a specific coordination mode, which is the brainchild of the inventor's many experiments

3. Each step of the present invention can be made into a ratchet with 90 矣 180 teeth without using special technology or equipment, which is quite in line with the value of the industry and worthy of promotion by the industry. 4. The method used in the present invention Because it can be more effective, its process design is quite attentive and can achieve a solid and practical purpose. It is an invention that the conventional process can't compare. It can be said to the industry as a breakthrough in the era of dichotomy. To sum up, the present invention is practically and cost-effectively used in accordance with the needs of industrial development, and the disclosed method invention is also an unprecedented innovation, so it should be considered as having "newness".

Therefore, according to the above, it can be seen that the process of the present invention is indeed more attentive and more "practical" than the previous process. Its unique features and functions are also far away. # The conventional process can be compared, so it is indeed comparable The conventional ones are more "progressive" and have not been found in published publications. They are more in line with the "novelty" requirements. They fully comply with the requirements of the patent law in China regarding the application requirements for invention patents. Please fish
