Description

Technical Field

[0001] This application belongs to the technical field of molds, and particularly relates to a forging mold for a three-way valve body. Background Art

[0002] At present, the multi-directional die forging forming process of three-way valve body forgings has been mature, and most forgings have achieved non-edge and three-way hole cavities. And most of them adopt dynamic die and static die forging, and the blank is placed in the mold cavity for forming when closing.

[0003] Half is the homophone of the English word "half", that is, one-half, which means dividing a template into multiple halves. Generally, it refers to half-blocks, which can be 2 or multiple.

[0004] Such as Figure 4 shown, it is the structure of the forming module of the half mold for machining the three-way valve body at present. However, this structure is difficult for the forming of the three-way valve body, so a larger blank is often used for forging, resulting in more material consumption. Utility Model Content

[0005] The purpose of this application is to provide a forging mold for a three-way valve body aiming at the above existing technical problems, which can save materials during the forging process of the three-way valve body.

[0006] This application provides a forging mold for a three-way valve body, including:

[0007] Forming modules, two forming modules are provided and symmetrically distributed, and the forming modules are provided with die cavity grooves;

[0008] Top punching hole, placed at the top of the forming module;

[0010] Among them, the top punching hole corresponds to the port at the middle position of the three-way valve body, and the side punching hole corresponds to the ports at both sides of the three-way valve body.

[0011] By making the top punching hole correspond to the port at the middle position of the three-way valve body and the side punching hole correspond to the ports at both sides of the three-way valve body, when forging, the blank can be filled into the die cavity groove more smoothly. Therefore, a blank with a smaller diameter can be used for forging, and less blank can be used for forging, which further effectively improves the utilization rate of the blank. The forming module consists of two parts, the die cavity groove corresponds to the three-way valve body to be forged, the blank is put in from the top punching hole, and pressure is applied to the top punching hole and the side punching hole respectively to complete the forging of the blank.

[0012] Furthermore, the forming module further includes:

[0013] Top punching groove;

[0014] Among them, the top punching hole is formed by a top punching groove.

[0016] Furthermore, it also includes:

[0017] A top punching needle, which is adapted to the top punching groove;

[0018] Among them, during forging, the top punching needle is inserted into the top punching hole.

[0019] During forging, the top punching needle is inserted into the top punching hole under the action of pressure and acts on the blank. A hole groove is formed at the middle port of the three-way valve body through the top punching needle, further improving the utilization rate of the blank and facilitating the subsequent cutting process of the three-way valve body forging.

[0020] Furthermore, the forming module further includes:

[0021] A side punching groove;

[0022] Among them, the side punching hole is formed by the side punching groove.

[0024] Furthermore, it also includes:

[0025] A side punching needle, which is adapted to the side punching groove;

[0026] Among them, during forging, the side punching needle is inserted into the side punching hole.

[0027] During forging, the side punching needle is inserted into the side punching hole under the action of pressure and acts on the blank. Hole grooves are formed at both ends of the three-way valve body through the side punching needle, further improving the utilization rate of the blank and facilitating the subsequent cutting process of the three-way valve body forging.

[0028] Furthermore, the forming module further includes:

[0029] A stepped surface, which is placed on the outer side wall of the forming module.

[0030] The installation and positioning of the forming module are facilitated through the stepped surface, and the installation stability during module use is improved.

[0031] Furthermore, the forming module further includes:

[0032] A chamfered surface, which is placed at the opening end of the top punching hole.

[0033] The stability of the top punching needle inserted into the top punching hole during forging is improved through the chamfered surface.

[0034] The beneficial effects of this application are as follows:

[0035] 1. By aligning the top punching hole with the port at the middle position of the three-way valve body and the side punching holes with the ports at both sides of the three-way valve body, when forging, the blank can be filled into the die cavity groove more smoothly. Therefore, blanks with a smaller diameter can be used for forging, enabling the use of fewer blanks for forging and further effectively improving the utilization rate of the blanks.

[0036] 2. During forging, the top punch needle is inserted into the top punching hole under the action of pressure and acts on the blank, forming a hole groove at the middle port of the three-way valve body through the top punch needle, further improving the utilization rate of the blank and facilitating the subsequent cutting process of the three-way valve body forging.

[0037] 3. During forging, the side punch needle is inserted into the side punching hole under the action of pressure and acts on the blank, forming hole grooves at both ends of the three-way valve body through the side punch needle, further improving the utilization rate of the blank and facilitating the subsequent cutting process of the three-way valve body forging.
