Embodiment Construction
[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0034] Such as Figure 1 to Figure 7 As shown, a valve valve body casting sprue cut-off processing machine includes a bottom plate 10 and a fixing device 30 arranged on the top of the bottom plate 10, a circular groove 11 is opened in the center of the top of the bottom plate 10, and the inner wall of the circular groove 11 is symmetrically opened on both sides. There is a telescopic slot 12, and the inside of the telescopic slot 12 is provided with an alignment device 20, wherein the alignment device 20 includes a telescopic plate 21 slidingly docked in the telescopic slot 12, and one end of the telescopic plate 21 is connected to the telescopic slot 12 by a second spring 23. The inner wall is fixedly connected, and the other end is provided with a...

The invention discloses a processing machine and processing method for cutting sprues of valve body castings. The invention uses an alignment device to adjust the position of the valve body so that it is located in the center of the fixing device, and uses a bidirectional motor to drive a bidirectional screw to make two sets of fixing plugs approach at the same time until the fixing plugs are inserted into the valve body, thereby fixing the valve body. The placement is stable, and the cutting incision is smooth; the invention drives two sets of ring cutters at the same time through a group of motors, so that the two sprues can be cut off at the same time, ensuring that the remaining length after the sprue is cut is the same, and a protective cover is set outside the ring cutter to avoid metal fragments Chips splash into the eyes of the operator; by setting a support plate on the top of the support rod, it plays an auxiliary support role for the valve body, and when the sprue is cut from top to bottom, the deformation of the connecting rod due to too much pressure is avoided.
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...
