[0040] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the billet during processing. During the processing, spherical workpieces are easy to roll and have great instability when stored. Therefore, a base forging is required to support and fix the sphere so that it can be stored stably.

[0041] In view of the above technical problems, the present application discloses a base forging, which supports the spherical workpiece by providing a support part, and limits the spherical workpiece by providing a clamping part, so that the spherical workpiece can be placed in one place without rolling, thereby ensuring the stability of the spherical workpiece when stored. The clamping claws of the clamping part can be close to or away from each other, and can be limited and fixed in different ways, and can also adapt to spherical workpieces of different sizes, and has a wide range of applications. Figures 1 to 5One embodiment of the present application is described.

[0042] like Figures 1 to 5 As shown, in this embodiment, the base forging includes a supporting portion 1 and a clamping portion 2 , the supporting portion 1 is used to support the spherical workpiece, and the clamping portion 2 is used to fix the spherical workpiece on the supporting portion 1 .

[0043] Specifically, the support portion 1 may include a base plate 3 and a support plate 4, wherein the support plate 4 is located above the base plate 3, and the two are connected by a support rod 5, wherein the base plate 3 is partially extended in the horizontal direction relative to the support plate 4, and for the convenience of description, the extended portion is referred to as an extension portion. A pad 6 is provided in the middle of the support plate 4, and an anti-skid protrusion is provided on the surface of the pad 6. In this embodiment, the pad 6 is made of rubber material, which has a certain elasticity. When the spherical workpiece is placed on the pad 6, the pressure-bearing part of the pad 6 is compressed downward, so that the middle of the pad 6 is concave, and the pad 6 is no longer a flat surface. Combined with the anti-skid protrusion, the spherical workpiece placed on the pad 6 will not roll easily when not subjected to external force, so that the clamping portion 2 acts on the spherical workpiece.

[0044] In this embodiment, the clamping portion 2 may include an upper limit structure and a lower limit structure. The lower limit structure is mainly used to limit the bottom of the spherical workpiece so that it does not displace in the horizontal direction. Of course, in some cases, it can also simultaneously play a role in limiting in the vertical direction, which will be further explained below in conjunction with the accompanying drawings; the upper limit structure is used to limit the spherical workpiece in the vertical direction so that it does not displace in the vertical direction.

[0045] Specifically, the lower limit structure includes a first driving structure, a connecting plate 13 and a ball 14. The connecting plates 13 are equidistantly arranged around the pad 6, and the number is not less than three. In the present embodiment, there are exactly three connecting plates 13, and there are also three ball 14. One side of all the connecting plates 13 is provided with an ear plate 15, and the end of any connecting plate 13 is correspondingly provided with two ear plates 15. The ball 14 is rotatably connected to the ear plate 15. The ball 14 is a cylindrical structure, and the diameter of its circular cross-section is larger than the width of the connecting plate 13 along the extension direction of the avoidance groove 18, and the two sides of the ball 14 are respectively grown out of a part of the connecting plate 13, and one end of the connecting plate 13 where the ball 14 is arranged gathers toward the middle direction. Driven by the first driving structure, the connecting plates 13 can approach or move away from each other to achieve the purpose of clamping and limiting the spherical workpiece.

[0046] For a complete spherical workpiece (a complete spherical workpiece refers to a workpiece without any openings on the sphere), the spherical workpiece is first placed on the pad 6, and the first driving structure drives the connecting plate 13 to move toward the middle until the ball 14 or the inner wall of the connecting plate 13 rests on the outer wall of the spherical workpiece. In this embodiment, the length of the connecting plate 13 is adjustable.

[0047] If the spherical workpiece is a workpiece with a circular opening, and the opening can accommodate three connecting plates 13 entering the cavity of the spherical workpiece at the same time, in addition to the above-disclosed limiting method, the following methods can also be adopted for limiting and fixing:

[0048] The first driving structure drives the connecting plates 13 to approach each other, and the spherical workpiece is sleeved on the connecting plates 13. Then the first driving structure drives the connecting plates 13 to move away from each other until the outer wall of the connecting plates 13 abuts against the inner edge of the opening of the spherical workpiece. An anti-slip layer can be provided on the outer wall of the connecting plates 13, and the upper limit structure can also be temporarily idle without limiting the spherical workpiece in the vertical direction.

[0049] By setting the ball 14, when the spherical workpiece is limited, the contact between the spherical workpiece and the ball 14 can prevent the edges of the connecting plate 13 from damaging the spherical workpiece, and the connecting plate 13 can be moved inward. The anti-slip layer on the outer wall of the connecting plate 13 provides two limiting methods for the spherical workpiece. One is for a complete spherical workpiece, the connecting plate 13 or the ball 14 is against the outer wall of the spherical workpiece, which can limit the spherical workpiece from rolling in the horizontal direction. The other is for a spherical workpiece with an opening, it can also be extended into the cavity from the opening of the spherical workpiece, and the outer wall of the connecting plate 13 is against the inner edge side of the opening, which is used to limit the displacement of the spherical workpiece in the horizontal direction. Of course, the limiting method for the complete spherical workpiece is also applicable to the spherical workpiece with an opening.

[0050] Further, the above-mentioned first driving structure may include a first driving member 8, a first bevel gear 9, a second bevel gear 10, a driving screw 11 and a sleeve 12, an installation cavity is provided on the support plate 3, a sinking plate is provided below the support plate 3, the sinking plate and the support plate 3 are respectively provided with a cavity, the two cavities are connected to form an installation cavity, the first bevel gear 9 and the second bevel gear 10 are respectively arranged in the installation cavity, an installation roller is provided in the installation cavity, the first bevel gear 9 and the second bevel gear 10 are respectively rotatably connected to the installation roller, wherein the first bevel gear 9 is provided with one, the number of the second bevel gear 10 matches the number of the connecting plate 13, and the second bevel gear 10 can respectively mesh with the first bevel gear 9, the driving member is provided on the base plate 2, and its driving end extends into the installation cavity and is connected with the first bevel gear 9, that is, the first driving member 8 can drive the first bevel gear 9 to rotate, and then drive the second bevel gear 10 to rotate. The support plate 3 is provided with a position-avoiding groove, in which the driving screw 11 is arranged, one end of which is connected to the second bevel gear 10, and the other end of which is rotatably connected to the groove wall of the position-avoiding groove, the shaft sleeve 12 is matched with the driving screw 11, and one end of the connecting plate 13 is matched with the shaft sleeve 12. It should be emphasized that the shaft sleeve 12 and the position-avoiding groove match, and the position-avoiding groove can play a role of limiting the shaft sleeve 12, so that the shaft sleeve 12 cannot rotate with the rotation of the driving screw 11, wherein the first driving member 8 can be a rotating motor, and its fixed end is arranged on the bottom plate 2.

[0051] The first driving structure described above, by using the cooperation between the first bevel gear 9 and the second bevel gear 10, can realize a situation where one driving member controls multiple driving rods to rotate simultaneously, thereby achieving the purpose of simplifying the structure without affecting the effect.

[0052] In an embodiment, Figure 1 As shown, the upper limit structure is arranged on the bottom plate 2, including the second driving member 7, the L-shaped connecting rod 16 and the pressing plate 17. The L-shaped connecting rod 16 is arranged on the extension of the bottom plate 2, the second driving member 7 is arranged on the L-shaped connecting rod 16, and the driving end of the second driving member 7 passes through the cross beam of the L-shaped connecting rod 16 and is connected to the pressing plate 17. By setting the upper limit structure, the support part 1 can be cooperated to realize the limitation of the spherical workpiece in the vertical direction.

[0053] The above is only a preferred embodiment of a base forging disclosed in the present utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present utility model, which all belong to the protection scope of the present utility model.
