Embodiment Construction

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0019] Refer to the attached figure 1 A combined insert mold 100 for the production of sector gear shafts according to an embodiment of the present invention is described.

[0020] Specifically, the sector gear shaft includes a cylindrical shaft and sector teeth connected to the shaft. The sector teeth are connected to the middle of the shaft in the longitudinal direction and protrude outward along the radial direction of the shaft. The sector teeth are formed so that the center of the circle is located at the center of the shaft. secto...

Abstract

The invention discloses a combined inserted die used for production of a sector gear shaft. The combined inserted die comprises a lower die bottom plate, a lower die assembly, a middle die assembly, an upper die bottom plate and an upper die assembly; the interior of a lower die cavity is in a detachable fit with a lower die insert; the interior of a middle die cavity is in a detachable fit with amiddle die insert; and the interior of an upper die cavity is in a detachable fit with an upper die insert. By installing the detachable lower die insert, middle die insert and upper die insert, notonly can mold cavities be defined for processing and forging the sector gear shaft, but also any insert can be rapidly replaced at low cost after being damaged, so that not only is a large amount of solder saved, is the maintenance cost of the combined inserted die reduced, and are the labor strength and the workload of a maintenance worker greatly reduced, but also the maintenance efficiency canbe promoted, the maintenance time is shortened, and the lost labor behavior caused by die maintenance can be further reduced; and moreover, since the combined inserted die is convenient to maintain, alarge number of standby dies do not need to be prepared in a manufacturing shop.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment processing, in particular to a combined mosaic mold used for the production of sector gear shafts. Background technique [0002] The fan-shaped gear shaft mold structure in the prior art is mostly an integral design. During the forging process, mold errors frequently occur, and the quality of the forgings is unstable, which leads to increased processing difficulty in the machining process, high scrap rate, and mold failure every time it is repaired. The mold cavity needs to be fully welded (20 kg welding wire), the working pressure of the electric welding process is high (overtime work every day), the repair cycle of each set of mold is one week, the maintenance cost is high, the life of the mold fluctuates and is extremely unstable, and cannot meet the continuous stability of the forging workshop Production demand, and the forging efficiency is low; in addition, the reproduction is t...
