Description

Technical Field

[0001] This utility model relates to the technical field of gear forging processing and unloading, specifically a gear forging ejection structure that is easy to disassemble. Background Technology

[0002] Forging refers to the process of applying pressure to a metal billet using forging machinery to cause plastic deformation and obtain forgings with certain mechanical properties, shapes and sizes. In the forging process of gear forgings, after forming, an ejection mechanism is needed to eject the gear forgings from the mold.

[0003] As disclosed in announcement number CN222695934U, a segmented ejection structure suitable for flat, thin, large-hole gear forgings is provided. It includes a rod and a head. The lower end of the rod is provided with a threaded section. The upper end of the head is a cylinder with a threaded hole at the top and four planes on its four sides. The lower end of the head is a conical structure, with the bottom of the head end serving as the contact surface with the forging. This contact surface has a raised structure and can fit against the connecting skin and part of the web of the forging. This invention achieves cost reduction by separating the rod and head and manufacturing them with different materials. Simultaneously, it increases the contact area between the head and the forging, effectively reducing the probability of deformed scrap parts during ejection.

[0004] However, the existing technology has the problem that the ejection structure is not universally applicable and is not convenient for ejecting gear-type forgings of different sizes from the mold. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose an easy-to-disassemble ejection structure for gear-type forgings. Utility Model Content

[0006] The purpose of this utility model is to provide an easy-to-disassemble ejection structure for gear forgings, so as to solve the problem that the ejection structure proposed in the background art is not universal and is inconvenient to eject gear forgings of different sizes from the mold.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gear-type forging ejection structure that is easy to disassemble, including a fixed connecting plate and a replaceable ejection rod;

[0008] Also includes:

[0009] A U-shaped mounting bracket is provided through the middle of the fixed connecting plate, and the mounting bracket and the fixed connecting plate form an up-and-down sliding structure.

[0028] 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.

[0029] Please see Figures 1-6 .

[0030] To address the problem that existing ejection structures lack versatility and are inconvenient for ejecting gear forgings of different sizes from the mold, this solution provides an easily detachable gear forging ejection structure. This structure includes a fixed connecting plate 1 and a replaceable ejector rod 7. A U-shaped mounting bracket 2 is installed through the center of the fixed connecting plate 1, and the mounting bracket 2 and the fixed connecting plate 1 form a sliding structure. Multiple sets of nested hollow connecting plates 4 and movable connecting plates 5 are arranged at equal angles on the side of the fixed connecting plate 1. An ejector rod 7 is positioned above the distal end of the movable connecting plate 5, allowing the movable connecting plate 5 to move the ejector rod 7 outside the fixed connecting plate 1.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, firstly, an ejector rod 7 of the appropriate length is selected according to the gear forging and the corresponding mold. A connector 8 is fixedly connected to the lower end of the ejector rod 7. By rotating the ejector rod 7, the connector 8 is threaded into the fixed mounting sleeve 6, facilitating the assembly of the ejector rod 7 and the movable connecting plate 5. After assembly, according to the size of the gear forging, the movable connecting plate 5 is pulled, allowing it to slide and extend with the hollow connecting plate 4. A fixed connecting strip 9 is fixedly connected to the lower end of the movable connecting plate 5. The movable connecting plate 5 drives the fixed connecting strip 9 to slide with the hollow connecting plate 4, causing the ejector rod 7 to move. This adjusts the distance between the ejector rod 7 and the fixed connecting plate 1, ensuring the distance matches the size of the gear forging. After adjustment, as shown... Figure 5 and Figure 6 As shown, by flipping the movable limiting post 12, the movable limiting post 12 and the auxiliary block 11 rotate. The movable limiting post 12 flips upward and engages in the fixed connecting groove 10 at the corresponding position at the lower end of the fixed connecting strip 9. Then, the fixing bolt 13 is rotated so that the fixing bolt 13 limits the movable limiting post 12, thereby facilitating the fixing of the fixed connecting strip 9, and thus limiting the space between the hollow connecting plate 4 and the movable connecting plate 5.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, after replacement and adjustment, the mounting bracket 2 is fitted onto the gear forging mold, and the ejector rod 7 is inserted into the corresponding hole in the mold. The upper end of the ejector rod 7 is fitted against the formed gear forging. The mounting bracket 2 is then fixed to the mold with bolts. The lower end of the fixed connecting plate 1 is fixedly connected to the connecting drive 3, which is connected to an external drive device for ejection. The drive device is an electric telescopic rod or other linearly driven equipment. After the gear forging is forged in the mold, the external drive device pushes the connecting drive 3 upward. The connecting drive 3 pushes the fixed connecting plate 1 to slide between the mounting bracket 2, so that the fixed connecting plate 1, together with the hollow connecting plate 4 and the movable connecting plate 5, drives the ejector rod 7 to move in the through hole in the mold. The ejector rod 7 ejects the gear forging from the mold. Multiple sets of ejector rods 7 are arranged radially on the outside of the fixed connecting plate 1 to prevent damage to the workpiece at the ejection point.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
