In order to achieve the above purpose, the present utility model provides the following technical solutions:
Referring to fig. 4 to 6, a positionable blank mold for forging forming a blank 100 is provided according to the present embodiment, comprising: the lower die 200 is provided with a cavity 210 in the lower die 200, and the inner wall of the cavity 210 is provided with a positioning groove 220 for placing the blank 100.
The shape of the cavity 210 in the lower die 200 is the shape that the blank 100 needs to be forged, in this embodiment, the cavity 210 is a tapered structure that tapers downward, and a protrusion is provided at the middle of the bottom of the cavity 210.
Of course, the shape of the cavity 210 may be adjusted according to practical situations, and is not specifically limited herein.
In this embodiment, the blank 100 is placed in the positioning groove 220 on the inner wall of the cavity 210 during forging, and the positioning groove 220 can be exactly clamped with the blank 100.
That is, when the blank 100 is to be forged, the blank 100 can be directly placed into the positioning groove 220 in the cavity 210 in the lower die 200, so that the blank 100 cannot move relatively in the lower die 200, and can be stably fixed in the positioning groove 220 during forging; besides, the positioning grooves 220 can be used for rapidly and accurately placing the blank 100 into the cavity 210, and in addition, the blank 100 is placed in the positioning grooves 220 in the same position during forging, so that the shape of finished products after forging is the same, and the stability of the products is improved.
Preferably, the cavity 210 has a symmetrical structure, and a cross-section perpendicular to the first direction is circular.
Specifically, in the present embodiment, the cavity 210 is a wholly downwardly tapered necked structure, and its cross-section perpendicular to the first direction is circular.
It will be appreciated that the shape of the cavity 210 depends on the shape of the desired finished product, which in this embodiment is a necked-down configuration approximating a truncated cone.
Preferably, the positioning groove 220 is an annular groove.
Specifically, in the present embodiment, the positioning groove 220 is an annular groove, and the axis of the positioning groove coincides with the axis of the cavity 210, and the annular groove is disposed on the inner wall of the cavity 210.
It can be appreciated that the whole blank 100 is in a cylindrical structure, and in order to enable the blank 100 to be placed in the cavity 210 quickly and stably, the positioning groove 220 is integrally formed as an annular groove, so that the shape of the positioning groove 220 can be matched with the shape of the blank 100, and the blank 100 can be placed in the positioning groove 220 stably and quickly.
Preferably, the positioning groove 220 has an inner diameter of 400mm.
Specifically, in the present embodiment, the inner diameter of the positioning groove 220 is 400mm, and the distance from the positioning groove 220 to the inner axis of the cavity 210 is 200mm.
It can be understood that in this embodiment, the blank 100 is specifically a cylindrical structure with a diameter of 400mm and a height of 250mm, and in order to prevent the blank 100 from falling out of the positioning groove 220, the diameter of the positioning groove 220 is also set to 400mm, so that the stability of the blank 100 in the cavity 210 can be increased, which is beneficial to improving the stability of the product.
Preferably, the positioning groove 220 is 100mm from the bottom surface of the cavity 210 in the first direction.
It will be appreciated that, in order to enable rapid forming of the blank 100 during forging, the blank 100 is mounted in the positioning groove 220 in the present embodiment, so that the blank 100 can be formed at a rapid speed and with good quality.
Preferably, a rounded corner is provided in the positioning groove 220.
Specifically, in the present embodiment, the positioning groove 220 is rounded, so that the mold is effectively prevented from cracking due to stress concentration.
Preferably, the corner radius is 15mm.
Specifically, in the present embodiment, the radius of the round is 15mm, which is set to match the round size of the billet 100, so that the positioning effect of the billet 100 and the stability at the time of forging can be improved.
Of course, the fillet size of the positioning groove 220 may be adjusted according to practical situations, so long as the blank 100 can be stably placed, which is not particularly limited herein.
Preferably, the lower die 200 is made of 5CrNiMo steel.
It will be appreciated that the lower die 200 is required to withstand a relatively high pressure as the primary pressure-bearing member, since the blank 100 is heated at a high temperature during forging, the lower die 200 is also required to withstand a relatively high temperature; the 5CrNiMo steel has good toughness, strength and high wear resistance as hot work die steel, and can also withstand the high temperature of the blank 100, so in this embodiment, the lower die 200 is preferably 5CrNiMo steel.
In summary, an embodiment of the present application provides a positionable blank mold, comprising: the lower die 200 is internally provided with a cavity 210, the cavity 210 is of a shrinkage structure which is tapered downwards, the inner wall of the cavity 210 is provided with a positioning groove 220 for placing the blank 100, the positioning groove 220 is an annular groove, the diameter of the positioning groove is 400mm and is matched with the diameter of the placed blank 100, the distance from the bottom of the cavity 210 is 100mm, the annular groove is internally provided with a round corner with the radius of 15mm, the round corner can reduce stress concentration, and the lower die 200 is placed to crack.
When the blank 100 needs to be forged, the blank 100 can be directly placed into the positioning groove 220 in the cavity 210 in the lower die 200, the blank 100 cannot relatively move in the lower die 200, and the blank 100 can be stably fixed in the positioning groove 220 during forging; besides, the positioning grooves 220 can be used for rapidly and accurately placing the blank 100 into the cavity 210, and in addition, the blank 100 is placed in the positioning grooves 220 in the same position during forging, so that the shape of finished products after forging is the same, and the stability of the products is improved.
