The change is that different design schemes are provided on the basis of some existing schemes, related part shapes are manufactured and improved by a new thinking, modules with different functions are formed by common precision original pieces on the market, a precision indexer receives station instructions output by a control unit under a controllable power condition, and products can be manufactured fully automatically by combining the flow of a special sensing and induction device control process with the compiling of a control program and an internet connection system.
From the implementation example, the structure and the rigid pivot of the product are redesigned, the traditional thinking of the original power is changed, the plasticity of the material is increased through the forging function of the hydraulic power, the material is changed from two-dimensional to three-dimensional through one or more processes, so that the cast inner structure effect is achieved in the final product, the surface meets the beautifying requirements of the pressing function and additional workers, and more importantly, the material of the built-in spring in the traditional mode is changed, so that the specification of the product is unified, the problems in the links of sale and recovery are reduced, and the acceptance of the product in the market is expanded; the whole design thinking is changed, and through numerical control and the communication function on the internet, the production cost can be reduced in the aspect of energy conservation, and the load of each part can be effectively controlled. The new processing technology can achieve the purpose of comprehensively transforming and optimizing the products, and a brand new route is provided for future chain buckle series, so that the energy is saved, the labor force is reduced, the quality is changed, and the product standardization is enhanced.
Because a new thinking mode can be realized after the numerical control technology is advanced in the future, the mode can have larger development space. Other than in the examples, or where otherwise indicated, all numbers expressing quantities of forms of reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term "about". Accordingly, unless indicated to the contrary, the numerical parameters set forth in the foregoing specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples set forth above are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
The above examples only show one embodiment of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
