Problems solved by technology
At present, only a few manufacturers use hot forging technology and molds to manufacture water meter shells, but there are no detailed literature reports on the specific process steps of hot forging and the specific structure of forging devices
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 amount of cutting processing is required to form the water meter casing
Due to the special shape of the water meter shell and the need for core pulling at the water inlet and outlet, it is very difficult to design the mold structure for one-time hot forging forming, the forming structure design is difficult, the mold opening structure design is even more difficult, and how to use the forging equipment Power is used to drive mold closing and opening, so it has not been effectively solved for a long time

The invention provides a forging and pressing device 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 device comprises a forging and pressing machine tool and a die (30), wherein the die (30) adopts a 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, the split 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, and a jacking rod is arranged under the die base; and a cross beam (35) is arranged below a die (30), the cross beam (35) is connected to a forging and pressing machine tool driving box (33) by means of connecting rods (36), the cross beam (35) is provided with a jacking bar (37), and the jacking bar (37) has a workingposition A aligned with the jacking rod (7) of the die (30) and a non-working position B. The water meter shell body forging and pressing device 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.
Description
technical field [0001] The invention relates to a forging device for a water meter casing, in particular to a forging machine tool and a mold for stamping a red-hot copper rod into a water meter casing at one time. Background technique [0002] A water meter is an instrument that records water consumption by measuring the flow of tap water. It mainly includes a water meter casing (also called a meter body) and a water meter movement and a cover. It is formed by forging. The water meter core is arranged in the concave cavity of the water meter casing, and the two sides of the water meter casing are respectively provided with a water inlet channel and a water outlet channel running through the cavity, and are respectively connected with water pipes. [0003] At present, the water meter shells sold in the market are mainly formed by casting process. The casting process produces a large amount of exhaust gas when the water meter shell blank is cast, and the rough shell wall is ...
