Description
Technical Field
The invention relates to the technical field of machining, in particular to a production process of a swing tooth.
Background
The existing swing tooth has two production processes, one is direct die-casting molding, and the other is machining and milling of tooth surfaces by steel; the disadvantages are: 1. the strength of die-casting molding is not enough, and the teeth are easy to break; the product has short service life, small transmission force and small shearing force; 2. in the machining of the steel, the tooth profile is a spline and is not in a standard tooth profile due to the milling of a profiling blade, so that the transmission is spline transmission and is not in gear engagement transmission, and the transmission efficiency is low; meanwhile, the processing efficiency is low, and the cost is high.
Therefore, a process for manufacturing the oscillating tooth is needed to solve the above problems.
Disclosure of Invention
In order to solve the problem, the invention discloses a production process of a swing tooth, which enables the swing tooth to be processed by steel materials, and can ensure the precision and the surface roughness of the tooth shape at the same time, so that the transmission strength and the transmission efficiency of the structure are improved. The production process of the swing tooth is characterized by comprising the following steps: blanking, forging shape, stamping, roughly forging tooth surface and finely forging tooth surface;
firstly, blanking: cutting the bar stock by a sawing machine to obtain the required size;
secondly, forging the shape: forging a bar stock to obtain the appearance of a product, and controlling the angle 01, the angle 02, the angle 03, the angle 04, the integral skin thickness 05 and the flash thickness 06;
thirdly, stamping: removing the connecting skin and flash generated in the previous step;
fourthly, rough forging of tooth surfaces: pre-forging the tooth surface, and controlling 07 the forming depth and shape of the tooth surface;
fifthly, fine forging of tooth surfaces: and (3) carrying out precision forging on the tooth surface, and controlling 08 the precision of the tooth surface to be more than 8 grades and the roughness to be more than 1.6.
Further, the present invention is formed by forging and press-forming the outer shape.
Further, the present invention is directed to forging profiles wherein control of the four angles of the tooth form portions affects the fullness of the final product.
Further, the invention forms and ensures tooth profile finish forging and roughness by rough forging tooth surface and finish forging tooth surface.
Further, the present invention may be used to forge a variety of similar wobble teeth other than those shown.
The invention has the beneficial effects that:
the product has high density, the tooth shape has a finished streamline, and the product strength is improved; the material utilization rate is high, and the waste is less; the processing efficiency is high.
