[0034] In some embodiments, the extrusion assembly 2 comprises a plurality of extrusion blocks 21, an extrusion slide rail 22, and a sliding groove 23. The plurality of extrusion blocks 21 are arranged in a ring shape outside the adjusting assembly 3 to form a circular extrusion working surface, ensuring the roundness of the iron cover. The extrusion slide rail 22 is arranged on the fixed base 1 to provide guidance for the sliding of the extrusion blocks 21. The sliding groove 23 is arranged at the bottom of the extrusion blocks 21 and is in sliding cooperation with the extrusion slide rail 22, allowing the extrusion blocks 21 to move radially along the direction of the extrusion slide rail 22.

[0035] In some embodiments, the extrusion assembly 2 further comprises a limiting block 24 and a limiting groove 25. The limiting block 24 is arranged on the side of the extrusion slide rail 22 away from the center, and the limiting groove 25 is arranged on the side of the sliding groove 23 away from the center. The limiting block 24 can slide in the limiting groove 25. Through the cooperation of the limiting block 24 and the limiting groove 25, the maximum movement distance of the extrusion blocks 21 can be limited, preventing the extrusion blocks 21 from moving excessively during the extrusion process and damaging the mold or affecting the forming quality of the iron cover.

[0036] In some embodiments, the adjusting assembly 3 comprises a fixed column 31, an adjusting platform 32, and a lifting groove 33. The fixed column 31 is arranged on the fixed base 1 to support and position the adjusting platform 32. The adjusting platform 32 is externally provided with a plurality of extrusion blocks 21. The outer surface of the adjusting platform 32 is in sliding connection with the inner surface of the extrusion blocks 21. By adjusting the up and down movement of the adjusting platform 32, the initial position and extrusion stroke of the extrusion blocks 21 can be changed, thereby adapting to the extrusion forming requirements of iron covers of different sizes. The lifting groove 33 is arranged at the bottom of the adjusting platform 32 and is in plug-in cooperation with the fixed column 31. A return spring 4 is arranged between the lifting groove 33 and the fixed column 31. During the extrusion operation, the impact block 5 impacts the adjusting platform 32, the adjusting platform 32 moves downward, and the return spring 4 is compressed. When the extrusion operation is completed, the impact force of the punch disappears, and the elastic force of the return spring 4 makes the adjusting platform 32 quickly return to the initial position, also providing certain auxiliary action for the reset of the extrusion blocks 21, ensuring that the entire mold can quickly return to the initial state and be ready for the next extrusion operation.

[0037] In some embodiments, the adjusting platform 32 can be an inverted conical platform. When the adjusting platform 32 moves up and down, it can uniformly push the extrusion blocks 21 outward through the contact between its conical surface and the inner surface of the extrusion blocks 21, ensuring the movement precision and stability of the extrusion blocks 21.

[0038] In some embodiments, the extrusion assembly 2 further comprises a reset ring groove 26 and a spring ring 27. The reset ring groove 26 is arranged on the outer surface of the plurality of extrusion blocks 21, and the spring ring 27 is arranged in the reset ring groove 26. After the extrusion operation is completed, the elastic force of the spring ring 27 can make the extrusion blocks 21 quickly return to the initial position, improving production efficiency.

[0039] In some embodiments, further comprising a fixed plate 7, two guide rails 8, the fixed plate 7 is provided with a shaping block 6 on one side, the two guide rails 8 are transversely arranged on the fixed plate 7, and the fixed seat 1 can slide on the two guide rails 8, through the guiding effect of the guide rails 8, the fixed seat 1 can drive the extrusion assembly 2 to move accurately to the shaping block 6, so as to realize the extrusion and shaping operation of the iron cover round line, and the work station for manually taking the iron cover can be away from the working area of the punch, thereby protecting the safety of the operator.

[0040] In some embodiments, further comprising a handle 9, the handle 9 is arranged on the side of the fixed seat 1 away from the shaping block 6, so as to facilitate the operator to manually push the fixed seat 1 to move on the guide rail 8, and improve the convenience of operation.

[0041] The specific working principle is as follows:

[0042] In specific operation, the operator places the iron cover to be processed on the extrusion assembly 2.

[0043] The operator holds the handle 9 and pushes the fixed seat 1 to slide on the guide rail 8, so that the extrusion assembly 2 approaches the shaping block 6.

[0044] After the fixed seat 1 is moved to the position, the punch is started, the impact force of the punch is transmitted to the adjusting table 32 through the impact block 5, the adjusting table 32 moves downward along the fixed column 31, and the return spring 4 is compressed. At the same time, the conical surface of the adjusting table 32 pushes the extrusion block 21 to move radially outward along the extrusion slide rail 22, so as to extrude the inner wall of the iron cover.

[0045] During the extrusion process, the shaping block 6 further extrudes and shapes the iron cover round line, so as to enhance the extrusion resistance of the round line.

[0046] After the extrusion operation is completed, the impact force of the punch disappears, the elastic force of the return spring 4 makes the adjusting table 32 move upward to return to the initial position, and the elastic force of the spring ring 27 makes the extrusion block 21 move radially inward to return to the initial position.

[0047] The operator holds the handle 9 and pulls the fixed seat 1 back along the guide rail 8, and then takes out the extruded and formed iron cover, so as to complete one extrusion and forming operation.
