Embodiment 1

[0031] figure 1 It is a schematic structural diagram of the concave anvil 100 for forging provided in Embodiment 1 of the present invention. see figure 1 , this embodiment provides a forging concave anvil 100 for forging large forgings. The forging concave anvil 100 has a concave surface 111, a bottom surface 120 and defines a reference plane 110. The reference plane 110 is opposite to the concave surface 111.

[0032] In this embodiment, the concave anvil 100 for forging generally has a cuboid structure as a whole. The concave anvil 100 for forging extends along the first direction 101, and has a length a in the first direction 101, and the concave anvil 100 for forging has a thickness formed between the concave surface 111 and the bottom surface 120 along the second direction 102, along the third direction 103 has width.

[0033] The concave surface 111 is a surface depressed in the second direction 102 , and the distance between it and the reference plane 110 gradually a...

Embodiment 2

[0044] figure 2 It is a schematic structural diagram of the concave anvil 200 for forging provided in the second embodiment of the present invention. see figure 2 The main difference between the forging concave anvil 200 provided in this embodiment and the forging concave anvil 100 provided in the first embodiment lies in the concave surface 111 .

[0045] In this embodiment, the concave anvil 200 for forging also has a first plane 201 and a second plane 202 . The concave surface 111 extends along the first direction 101 , and the edges 104 of two sides of the concave surface 111 coincide with the first plane 201 and the second plane 202 respectively.

[0046] In this embodiment, both the first plane 201 and the second plane 202 are on the same plane, and both are coplanar with the reference plane 110 . In other embodiments of the present invention, the relative positional relationship between the first plane 201 and the second plane 202 can be changed according to the si...

Embodiment 3

[0052] image 3 It is a structural schematic view of the first viewing angle of the concave anvil 300 for forging provided by the third embodiment of the present invention. see image 3 One difference between the forging concave anvil 300 provided in this embodiment and the forging concave anvil 100 provided in Embodiment 1 lies in the concave surface 111 . In this embodiment, the concave surface 111 also has a planar region 301 , and the planar region 301 is relatively parallel to the reference plane 110 . The distance between the planar area 301 and the reference plane 110 is constant, and the distance is equal to the maximum distance between the concave surface 111 and the reference plane 110 . That is, in the second direction 102 , relative to the reference plane 110 , the concave surface 111 has a maximum depth b equal to the distance between the plane region 301 and the reference plane 110 .

Abstract

The invention provides a concave anvil used for forging and a forging device and belongs to the field of machinery. The concave anvil used for forging is provided with a concave surface, and a reference plane opposite to the concave surface is defined on the concave anvil. The distance between the concave surface and the reference plane is gradually and synchronously decreased from the center to the two ends of the concave surface. The difference value between the maximum distance and the minimum distance between the concave surface and the reference plane is 3.5 mm-6.5 mm. The forging device comprises the concave anvil used for forging. According to the concave anvil used for forging, the defect problem of a forging is solved, so that the fiber structure of the forging and the shape of the forging are kept consistent, the metallurgical quality of the forging is improved, and meanwhile, the forging cost is also reduced.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a concave anvil for forging and a forging device. Background technique [0002] Judging from the development of world industry, the demand for large forgings in electric power, metallurgy, chemical industry and other industries is becoming stronger and stronger. The weight of large forgings is constantly increasing, and the requirements for their performance and quality are constantly improving.
