Description

Technical Field

[0001] This utility model relates to the field of anvil mold tooling technology, and in particular to high-performance anvil mold tooling for special steel forgings. Background Technology

[0002] Special steel forgings refer to forgings made of special steel (high alloy steel, stainless steel, tool steel). Special steel forgings have fatigue resistance, can withstand load cycles without cracking or breaking, have strong wear resistance, and are suitable for harsh mechanical working conditions. Special steel has good machinability and can be finely machined through forging and cutting processes to form complex geometric shapes. Forging requires the use of anvils and die fixtures, which are mainly used to forge special steel forgings inside the cavity opened on the surface of the anvil and die fixture.

[0003] During long-term forging, the cavity of the anvil tooling is exposed on the surface of the die, and the contact between the cavity and the workpiece will generate a lot of friction. Especially under the condition of large impact force, the cavity surface is prone to wear, which leads to a reduction in the dimensional accuracy of the forging and the occurrence of dimensional defects. Therefore, a high-performance anvil tooling for special steel forgings is designed. Utility Model Content

[0004] The purpose of this utility model is to provide a high-performance anvil die tooling for special steel forgings, in order to solve the problem mentioned in the background art that the cavity surface is prone to wear under large impact forces, which leads to a reduction in the dimensional accuracy of the forgings and the occurrence of dimensional defects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance anvil mold tooling for special steel forgings, including a pressure-resistant table, an anvil mold platform on the top of the pressure-resistant table, multiple abutment blocks on the outer walls of both the pressure-resistant table and the anvil mold platform, support plates fixedly installed on both sides of the pressure-resistant table, hydraulic cylinders on the top of the two support plates, and adjustment plates driven by the output shafts of the two hydraulic cylinders, with extension plates between the inner walls of some of the abutment blocks, and an arc-shaped plate fixedly installed on one side of four of the abutment blocks.

[0006] As a preferred embodiment of this utility model, two card holes are provided at the top of each of the two extension plates, and convex strips are provided inside the four arc-shaped plates.

[0007] As a preferred embodiment of this utility model, one end of each of the four protrusions is engaged with the interior of one of the four card holes.

[0008] As a preferred technical solution of this utility model, a screw is movably inserted between two adjacent abutting blocks, and nuts are threaded onto both ends of the multiple screws.

[0009] As a preferred embodiment of this utility model, the positions of the two adjacent abutment blocks are corresponding.

[0010] As a preferred embodiment of this utility model, two reinforcing plates are fixedly installed at the top of each of the two support plates, and one side of each of the two adjustment plates is close to the two sides of the anvil mold table.

[0011] As a preferred embodiment of this utility model, the positions of the two adjacent reinforcing plates are corresponding.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model incorporates abutment blocks, hydraulic cylinders, adjusting plates, extension plates, protrusions, and locking holes. After the bottom surface of the anvil and the top of the pressure-resistant platform approach each other, one end of each of the four protrusions is embedded into the corresponding locking holes. At this point, the abutment blocks are in contact with each other, positioning the anvil onto the surface of the pressure-resistant platform. Activating the two hydraulic cylinders drives the adjusting plates, which are connected to their output shafts, to move left and right. After the two adjusting plates move relative to each other, they clamp the two sides of the anvil, further ensuring the firmness of the installation between the anvil and the pressure-resistant platform and keeping the anvil in a centered position. This structure allows for easy replacement of the anvil if it is damaged, thereby improving the quality of special steel forgings.

[0014] 2. This utility model, by setting up a screw, nut, support plate and reinforcing plate, allows two adjacent abutment blocks to fit tightly together. The screw is then inserted between the two abutment blocks, and two nuts are threaded onto the two ends of the screw in sequence, thereby limiting and fixing the two abutment blocks. This enables the installation of the pressure table and the anvil table. The four reinforcing plates can abut one side of the multiple abutment blocks at the top, making the fit with the abutment blocks at the bottom more precise and improving the practicality of the anvil tooling.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a high-performance anvil die tooling for special steel forgings:

[0022] Example 1:

[0023] like Figure 1-3 As shown, the high-performance anvil die tooling for special steel forgings includes a pressure-resistant table 1, an anvil die table 2 on the top of the pressure-resistant table 1, multiple abutment blocks 3 on the outer walls of both the pressure-resistant table 1 and the anvil die table 2, support plates 6 fixedly installed on both sides of the pressure-resistant table 1, hydraulic cylinders 7 on the top of the two support plates 6, and adjustment plates 8 driven by the output shafts of the two hydraulic cylinders 7. Extension plates 10 are provided between the inner walls of some of the abutment blocks 3, and arc-shaped plates 13 are fixedly installed on one side of four abutment blocks 3. When the two hydraulic cylinders 7 are activated, the adjustment plates 8 driven by their output shafts move left and right. After the two adjustment plates 8 move relative to each other, they clamp the two sides of the anvil die table 2 respectively, further ensuring the firmness of the installation of the anvil die table 2 and the pressure-resistant table 1, so that the anvil die table 2 is in a centered state. With this structure, the anvil die table 2 can be replaced if it is damaged.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4 As shown, a screw 4 is movably inserted between each of the two adjacent abutment blocks 3. Nuts 5 are threaded onto both ends of the screws 4. Two reinforcing plates 9 are fixedly installed on the top of each of the two support plates 6. One side of each of the two adjusting plates 8 is close to the two sides of the anvil mold table 2. By setting up the screws 4, nuts 5, support plates 6 and reinforcing plates 9, after the two adjacent abutment blocks 3 are tightly fitted together, the screws 4 are inserted between the two abutment blocks 3. The two nuts 5 are then threaded onto the two ends of the screws 4 respectively, which can limit and fix the two abutment blocks 3, thereby realizing the installation of the pressure table 1 and the anvil mold table 2.

[0026] Working Principle: Special steel forgings refer to forgings made of special steel materials such as high-alloy steel, stainless steel, and tool steel. Special steel forgings possess fatigue resistance, can withstand load cycles without cracking or fracture, and have strong wear resistance, making them suitable for demanding mechanical working conditions. Special steel has good machinability and can be precision-machined through forging and cutting processes to form complex geometric shapes. Forging requires the use of anvils and die fixtures. The main purpose is to forge the special steel forgings inside the cavities opened on the surface of the anvil and die fixture. During long-term forging, the contact between the cavity and the workpiece generates a large amount of friction, especially under high impact forces. This can easily cause wear on the cavity surface, leading to reduced dimensional accuracy of the forgings and resulting in dimensional defects. Therefore, a high-performance anvil and die fixture for special steel forgings is designed. After the bottom surface of the anvil table 2 and the top of the pressure-resistant table 1 approach each other, one end of each of the four protrusions 14 is embedded into the corresponding clips. Inside hole 15, at this time, every two abutment blocks 3 are in contact with each other, which can position the anvil 2 onto the surface of the pressure-resistant table 1. Activating two hydraulic cylinders 7 drives the adjusting plate 8, which is connected to its output shaft, to move left and right. After the two adjusting plates 8 move relative to each other, they clamp the two sides of the anvil 2, further ensuring the firmness of the installation between the anvil 2 and the pressure-resistant table 1, and keeping the anvil 2 in a centered position. This structure allows for replacement of the anvil 2 if it is damaged, thereby improving the forging quality of special steel forgings. After two adjacent abutment blocks 3 are tightly fitted together, the screw 4 is inserted between the two abutment blocks 3, and the two nuts 5 are threaded onto the two ends of the screw 4 respectively, thus limiting and fixing the two abutment blocks 3, and then installing the pressure-resistant table 1 and the anvil 2. The four reinforcing plates 9 can abut one side of the multiple abutment blocks 3 at the top, making their fit with the abutment blocks 3 at the bottom more precise, improving the practicality of the anvil tooling.
