TECHNICAL FIELD
[0001] The application relates to the technical field of forging dies, in particular to a ball valve body forging forming die. BACKGROUND
[0002] A ball valve is a valve in which the closure member (ball) is moved to the fully open or fully closed position by means of a valve stem and rotates through 90 degrees to open or close pinhole. Ball valves are used for on / off service in full flow applications. They differ from globe valves in that they use a ball shaped disc instead of a globe shaped disc. Ball valves are of three types: trunnion ball, floating ball and solid ball. The forging die refers to a tool that can shape the blank into a die forging. The forging die is a key process equipment in die forging production, and is a tool that needs to be used every stroke of the equipment. It plays an important role in die forging production.

DETAILED DESCRIPTION
[0020] Based on this, in order to improve the problem that the entire die needs to be replaced after the partial position of the die in the related art is damaged, the use cost of the die is high, the embodiments of the application provide the following solutions.
[0021] The following will be described in detail in combination with Figure 1 and Figure 2 The utility model is further described in detail.
[0022] The embodiment discloses a ball valve body forging forming die: a ball valve body forging forming die comprises a base 1, a plurality of modules 2 and a fixing mechanism, the base 1 is provided with a mounting groove 11, the modules 2 are movably arranged in the mounting groove 11, the modules 2 are provided with mold cavities 21, the mold cavities 21 on the modules 2 are communicated to form a total mold cavity 21, the fixing mechanism is arranged on the base 1 and used for fixing the modules 2, the base 1 is symmetrically provided with two extrusion columns 4, the base 1 and the two modules 2 at the end are provided with sliding grooves 12, and the extrusion columns 4 are slidably arranged in the sliding grooves 12;
[0023] One side surface of the mounting groove 11 and one side surface of each module 2 matched with the one side surface are inclined surfaces;
[0024] The fixing mechanism comprises a fixed plate 31 and a transmission assembly, the fixed plate 31 is slidably arranged in the mounting groove 11, one side of the fixed plate 31 abuts against one module 2 at the end, and the transmission assembly is used for moving and fixing the fixed plate 31;
[0025] The transmission assembly comprises a threaded rod 321, one end of the threaded rod 321 is rotatably connected to the side of the fixed plate 31 away from the module 2 and is threadedly connected to the base 1, and a handle 322 is fixedly arranged on the end of the threaded rod 321 away from the fixed plate 31.
[0026] As can be seen from the above, the ball valve body forging forming die provided by the embodiment of the application is used to install the die, the base 1 is installed on the fixed platform, then the two ends of the extrusion columns 4 away from the base 1 are connected to the horizontally movable hydraulic machine, and then the base 1 of the die without the two extrusion columns 4 is installed on the vertical hydraulic machine, so that the two sets of dies are opposite to each other. When the die is used to forge the blank, the blank is placed in the total die cavity 21, the vertical hydraulic machine drives the die at the top to move downward and abut against the die at the bottom, then the horizontal hydraulic machine drives the two extrusion columns 4 to move into the total die cavity 21, and the blank is shaped into the shape of the total die cavity 21, i.e. the shape of the ball valve body, under the extrusion of the two sets of dies 2 and the two extrusion columns 4. After the die is used for a long time, some dies 2 may be cracked or damaged, at this time, the threaded rod 321 is twisted to rotate by the handle 322, the fixed plate 31 is driven by the threaded rod 321 to slide away from the dies 2, the fixed plate 31 is separated from the dies 2, so that the fixing mechanism is released to fix the dies 2, then the damaged dies 2 are taken out of the installation groove 11 and replaced with new dies 2. When the new dies 2 are put in, the inclined surface allows the worker to not have to align the dies 2 with the installation groove 11, but only needs to roughly place the dies 2 in the installation position, and the dies 2 can automatically slide into the installation position under the action of gravity, which can facilitate the operation of the worker. After the new dies 2 are replaced, the fixed plate 31 is moved and pressed on the dies 2 by twisting the threaded rod 321, and the dies 2 are fixed, so that it is not necessary to replace all the dies 2, and the use cost of the die can be reduced.
[0027] In some embodiments, referring to Figure 2 and Figure 3 , the first limiting strips 13 are arranged on the two sides in the base 1, the first limiting grooves 22 are arranged on the two sides of each die 2, and the first limiting strips 13 are slidably connected in the first limiting grooves 22.
[0028] The second limiting strips 14 are further arranged in the base 1, the second limiting grooves 311 are arranged on the side of the fixed plate 31 close to the second limiting strips 14 and on the side of each die 2 close to the second limiting strips 14, and the second limiting strips 14 are slidably connected in the second limiting grooves 311.
[0029] In this way, when the module 2 is replaced, the fixed plate 31 is first moved to a position away from the module 2 by a certain distance, then the module 2 closest to the fixed plate 31 is pushed to slide towards the fixed plate 31, the first limiting strip 13 is slid out of the first limiting groove 22, the module 2 can be taken out from the inside of the installation groove 11, then the modules 2 can be taken out in order; the first limiting strip 13 can be matched with the first limiting groove 22 to limit the vertical movement of the module 2, so that the situation that the modules 2 at the top cannot be aligned or the modules 2 fall off from the inside of the installation groove 11 under the action of gravity can be avoided; the second limiting strip 14 can keep the position of the module 2 neat when the module 2 slides with the fixed plate 31, so that the cooperation between the modules 2 is more compact, and the processing precision of the die on the blank is improved.
[0030] Optionally, in some embodiments, referring to Figure 2 and Figure 3 , the clamping holes 23 are arranged on the two symmetrical sides of each module 2.
[0031] In this way, the worker can clamp or place the module 2 through the forging tongs matched with the clamping holes 23, and the replacement of the module 2 by the worker can be facilitated.
[0032] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
