Abstract

The invention is a cutting processing machine and processing method for valve body casting pouring openings. The cutting processing machine comprises a bottom plate and a fixing device arranged on thetop of the bottom plate, wherein the center of the bottom plate is symmetrically provided with alignment devices, and the top of the bottom plate is also provided with a cutting device. The inventionuses the alignment devices to adjust the position of the valve body to make the valve body located at the center of the fixing device, and uses a bidirectional motor to drive a bidirectional screw tomake two sets of fixing plugs approach at the same time until the fixing plugs are inserted into the valve body, so that the valve body is fixed and stably placed, and the cutting incision is flat. The invention drives two sets of ring cutters through a set of motors at the same time to cut the two pouring openings at the same time to ensure that the remaining lengths of the pouring openings after the cutting are the same, provides a protective cover outside the ring cutters to prevent metal debris from splashing into the eyes of the operator, and provides a support plate on the top of the support rods to assist to support the valve body, thereby preventing the connecting rods from deforming due to excessive pressure when the pouring openings are cut from top to bottom.

Description

technical field [0001] The invention relates to the technical field of valve body finishing, in particular to a processing machine and a processing method for cutting a sprue of a valve body casting. Background technique [0002] The three-way valve is a control component in the fluid delivery system, which has the functions of cut-off, adjustment, flow diversion, prevention of reverse flow, pressure stabilization, diversion or overflow, etc., and the valve body is a main part of the valve, which varies according to the pressure level. Mechanical manufacturing methods, such as: casting, forging, etc., the valve body of medium and low pressure specifications is usually produced by casting process. When the valve body is formed, in order to make the molten iron quickly fill the mold, the pouring port is usually added. There are two pouring ports on the outer wall of the valve body of the three-way valve. After the valve body is formed, it needs to be finished, including the re...
