Background
The main characteristic is that the hinge sheet is divided into a sub-sheet and a main sheet, the sub-sheet and the main sheet are both arranged on the hinge shaft and form hinge connection, and are all in the same tangential direction of the hinge shaft, the sub-sheet is similar to a part of the main sheet which is hollowed out, the sub-sheet can rotate 360 degrees around the central shaft and can be embedded into the main sheet to form a complete sheet. Compared with a casement hinge, the primary and secondary hinges are suitable for installation in the door frame in the middle, at a shallow depth and close to the side, the positions (grooves) of the door leaf fixing hinges do not need to be cut out like the casement hinge, the size of the gaps between the door frame and the door leaf is reasonable, the overall attractive effect is not damaged, and the installation is rapid and convenient.
When the parent hinge is manufactured, a method for producing the hinge in a separated mode of an inner sheet and an outer sheet is generally adopted, and then a series of complicated steps are carried out, and finally a finished product is assembled. The manufacturing process is complicated, the production efficiency is low, the problem of large color difference of surface treatment of the sub-page and the mother page, such as electroplating, spraying and the like, caused by different batches is easy to occur, and particularly, the split production method is easy to cause poor horizontal linearity, inflexible rotation and poor flatness of a scroll;
the primary and secondary hinge pieces are convenient to use and install, low in noise and convenient to use, but the primary and secondary hinge pieces are formed by cutting one hinge plate, so that the structural strength of the primary hinge piece is reduced, and after the primary and secondary hinge pieces are stressed for a long time in the using process, the service life of the primary and secondary hinge pieces is greatly influenced due to the fact that the door is suddenly opened and closed, so that the primary and secondary hinge pieces are synchronously manufactured.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a synchronous manufacturing method of a master-slave hinge plate, which aims to solve the problems in the background art.
In order to achieve the purpose, the invention provides the following technical scheme: a synchronous manufacturing method of a master-slave hinge sheet comprises the following steps:

In one embodiment, the depth of the groove 8 is one quarter of the diameter of the reinforcing rod 22. During operation, the depth of the groove 8 is set to be one fourth of the diameter of the reinforcing rod 22, so that the reinforcing rod 22 in a normal state cannot be easily broken, and only when impact force is not weakened through the supporting plate 21 and directly acts on the reinforcing rod 22, the reinforcing rod 22 can be broken to release the impact force, and the service life of the reinforcing rod 22 is prolonged.
When the combined hinge plate works, the combined hinge plate is convenient to use and mount, low in noise and convenient to use, but the combined hinge plate is formed by cutting one hinge plate, so that the structural strength of the combined hinge plate is reduced, and after the combined hinge plate is stressed for a long time in the using process, the door is suddenly stressed due to violent opening and closing, so that the service life of the combined hinge plate is greatly influenced, therefore, the support unit 2 is fixedly mounted in the clamping groove 1 of the combined hinge plate, and when the combined hinge plate is superposed with the combined hinge plate through the support force of the support unit 2, the support unit 2 can support the combined hinge plate, so that the bidirectional stress of the combined hinge plate is reduced, the structural strength of the combined hinge plate is enhanced, and the service life of the combined hinge plate is prolonged; specifically, when the sub hinge leaves rotate gradually to coincide with the clamping groove 1, the sub hinge leaves are firstly contacted with the supporting plate 21 in the clamping groove 1, and the supporting plate 21 is made of a spring rod material and has certain elasticity, so that the supporting plate 21 can generate certain elastic deformation under the action of force, and the supporting plate 21 provides certain buffering, so that the effect of the sub hinge leaves on the supporting plate 21 cannot coincide suddenly when the door is closed suddenly, and further the damage of the main hinge leaves due to bidirectional stress is caused; two simultaneously constitute triangle-shaped between backup pad 21 and the stiffener 22, triangle-shaped has stability, thereby guarantee that backup pad 21 still can resume initial condition when receiving the striking many times, and the reinforcing rope 23 that both sides were equipped with can provide certain pulling force when backup pad 21 warp, thereby make backup pad 21 surpass the limit and cause permanent deformation when permanent reciprocal elastic deformation, consequently, provide pulling force at the in-process that backup pad 21 resumes through reinforcing rope 23, thereby accelerate backup pad 21's recovery rate, also improve backup pad 21's life greatly simultaneously, the structural strength of female hinge piece has been strengthened, and then improve the holistic life of primary and secondary hinge piece.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
