Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
On the contrary, this application is intended to cover any alternatives, modifications, equivalents, and alternatives that may be included within the spirit and scope of the application as defined by the appended claims. Furthermore, in the following detailed description of the present application, certain specific details are set forth in order to provide a better understanding of the present application. It will be apparent to one skilled in the art that the present application may be practiced without these specific details.
FIG. 1 is a schematic illustration of a process for forming a cam rocker structure according to some embodiments of the present application; FIG. 2 is a schematic diagram of a process for forming a cam rocker structure according to some embodiments of the present application; the following describes in detail a forming process of a cam rocker structure according to an embodiment of the present application with reference to fig. 1 and 2. It should be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.
In the embodiment of the present application, as shown in fig. 1 and 2, the forming process of the cam rocker 2 structure includes the following steps:
the first step is as follows: the method comprises the following steps of blanking, punching and processing an iron coil into a cam body 1 with a connecting part at one end and a cavity at the other end by utilizing a progressive die; the two cam bodies 1 are buckled to form a cam; the cavity end of the cam body 1 is simultaneously punched to form a limiting opening,
the second step is that: the bent end part of the connecting part is arranged in the strip-shaped hole of the swing rod 2, and meanwhile, the swing rod 2 is rotatably connected to the connecting part of the cam body 1 through the rivet 3.
The application provides a cam structure forms for adopting two 1 locks of cam body, compares traditional adoption iron-based powder metallurgy sintering cam that form, and it is not solid, therefore dead weight greatly reduced, as shown in fig. 3. Simultaneously, cam body 1 utilizes modulus of continuity unloading fast production processing to form through the iron book, and two cams are buckled to form a whole, and then get up through rivet 3 riveting with pendulum rod 2 and constitute cam pendulum rod 2 subassembly, realize the corresponding function of lock body, and the production efficiency of this kind of structure technology is high, and product comprehensive cost is low.
In some embodiments, the spacing port is in the form of two oppositely disposed sectors. The limiting port is used for being matched with parts on the lock body.
The invention also provides a cam swing rod 2 structure which is prepared by any one of the forming processes of the cam swing rod 2 structure. The cam swing rod 2 structure prepared by the process has the advantages of greatly improving the production efficiency, improving the production efficiency by 50 percent, greatly reducing the material cost and reducing the product cost by about 30 percent.
The invention also provides a lock body which comprises the cam swing rod 2 structure. Due to the adoption of the cam swing rod 2 structure, the preparation efficiency of the lock body is greatly improved, and the production cost is greatly reduced. And the mass of the formed lock body is greatly reduced.
In some embodiments, the rivet 3 is a flat-head rivet 3, which facilitates the formation of a two-sided stop after riveting, and the flat head prevents interference with other components inside the lock body after assembly.
The forming process of the cam oscillating bar structure disclosed by the application can bring beneficial effects including but not limited to: the problems that the cam of the lock body is sintered by adopting an iron-based powder metallurgy process, the production efficiency is low, and the manufacturing cost of the product is high are solved. After the structural innovation is optimized, the stamping process is adopted for production, the iron coil material can be quickly produced and processed by utilizing the blanking of the progressive die, the cam can be assembled and used after riveting, the production and processing efficiency of the product can be improved by about 35% after the structural process is optimized and improved, the product cost is reduced by about 30%, and therefore the purpose of improving the market competitiveness of the product is achieved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
