Problems solved by technology

At present, only a few manufacturers use hot forging technology and molds to manufacture water meter housings, but there are no detailed literature reports on the specific process steps of hot forging and the specific structure of molds.
Moreover, as far as the applicant in this case knows, the water meter casing and its inlet and outlet ports still cannot be formed by stamping through holes at one time, and a large amoun

Embodiment Construction

[0028] the following to Figure 1 to Figure 9 As shown, the specific implementation manner of the preferred embodiment of the present invention is described.

[0029] A water meter casing 15 forging mold, used for one-time forging and forming of the water meter casing 15; figure 1 As shown, the forging die includes a base 1, a disc-shaped mold base 2 fixedly installed on the base 1, and a bottom hole 3 is opened in the middle of the base 1; it also includes a mold base 8 and core-pulling sliders 4 on both sides, and a mold core 5. Punch 6 and ejector pin 7.

[0030] Such as figure 1 , figure 2 As shown, the center of the mold base 2 is provided with a through-cavity 9 for accommodating the mold base 8. The mold base 2 runs through the cavity 9 and the mold base 8 matched with it forms a rectangle with four-corner arc transitions on the horizontal plane. Its side wall is an inclined wall, and the relatively inclined walls around the cavity 9 of the formwork 2 are respectively

Abstract

The invention provides a forging and pressing die which is used for punching a red-hot copper rod into a water meter shell body in one step. The water meter shell body forging and pressing die adoptsa water meter shell body cavity formed by combining a pair of Half die cores, the die cores are arranged in a die base formed by combining a pair of Half die bases and having inclined outer walls, thesplit positions of the Half die bases are provided with core-pulling sliding blocks, the Half die bases are arranged in a penetrating cavity with die carrier sidewalls being inclined walls, a jackingrod is arranged under the die base, and the jacking rod jacks up to drive the Half die bases, the Half die cores and the core-pulling sliding blocks to move upwards to open along the die carrier sidewalls being the inclined walls. The water meter shell body forging and pressing die has the advantages of high production efficiency and convenient and rapid operation, and solves the one-time hot forging and pressing forming problem and the die opening and piece taking-out problem of the water meter shell body invention.
