Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed arbitrarily, and the layout of the components may be more complicated.

As shown in fig. 4, the present application provides a valve cap marking mold for marking a blank for manufacturing a valve cap, the valve cap includes a large head and a small head, the large head has a diameter larger than that of the small head, the valve cap marking mold includes a body 10, an inner wall 11 of the body 10 is annular, and an outer wall 12 of the body 10 is inclined in a slope shape from one end to the other end thereof.

As shown in fig. 1-3, the utility model is used for the small-head mark before the forging of the valve cover into the die; the valve cover number printing die is used and can be directly used for embossing the size required by the product small head on the blank. The specific working process is as follows: (1) rolling and flattening the blank after the blank is completely forged, (2) engraving a small head shape and size by using a marking mold; (3) and then the product is fed into a die for upsetting and forming. Utilize the valve gap number seal mould of present case, can forge out microcephaly shape and size fast, reduce forging weight and material loss, production efficiency is high, and the disability rate is low to practice thrift follow-up processing cost. Fig. 1 shows the shape of the blank before the mark as a rectangular parallelepiped, fig. 2 shows the shape of the blank after the mark as an irregular blank with a small head, and fig. 3 shows the valve cover product after the die upset forming.

The outer wall 12 of the body 10 is inclined in a slope shape from one end to the other end, so that an included angle between the outer wall 12 and the inner wall 11 is 30-75 degrees, in the angle range, when number printing is facilitated, the body 10 applies force to a blank to form a small head, preferably, the included angle between the outer wall 12 and the inner wall 11 is 45 degrees, and the valve cover is suitable for manufacturing more valve covers with small heads and large heads.

The wall thickness formed by the outer wall 12 and the inner wall 11 gradually increases from one end to the other end, and the slope structure is beneficial to the body 10 to apply force to the blank.
