Abstract

[Use of article]; This design article is a set of rolling molds used to produce screws, including two die plates that move relative to each other to create screw threads. Both dies have bevels that impress the threads onto the outer surface of the screw placed between the two dies. ;[Design description];The design features of this design are as shown in the attached picture. The set of items includes left and right tooth plates. The corresponding end surfaces of the left and right tooth plates are respectively equipped with diagonally extending and gradually expanding tooth rubbing patterns. The cut marks and the tooth-rubbing cut marks form an array of multiple grooves and thin strips of cut marks. ;The three-dimensional view of the right die plate in the figure is viewed from the bottom, and the upper left part of the figure is truncated. In actual use, the right die plate is a complete plate.

Description

Dental plate set

The design article is a set of rolling dies for producing a screw, comprising two dental plates, the two dental plates moving relative to each other to manufacture a screw ridge. Both jaws have chutes that emboss the threads on the outer surface of the screw placed between the two plates.

The design features of the design are as shown in the figure. The group of articles includes the left and right slabs, and the corresponding end faces of the left and right dies are respectively provided with obliquely extending and gradually expanding ridge lines and ridge lines. The plurality of grooves and thin strips are formed on the incision to form an array of slits.

The perspective view of the right tooth plate of the figure is viewed from the bottom, and the upper left of the figure is a truncated representation, and the right tooth plate is actually used as a complete plate.
