Description

Technical Field

[0001] The utility model relates to the technical field of forging devices, and specifically relates to a split forging device for I-shaped precision alloy forgings. Background Technique

[0002] The main principle of split forging is to establish a material split cavity or split channel in the forming part of the blank or die. During the forging process, while the material fills the cavity, part of the material flows into the split cavity or split channel, so as to obtain forgings with better filling degree.

[0003] In this regard, Chinese Patent Application No.: CN202221824376.0 discloses a gear forging die, which includes a die cover plate, a gear-shaped forging die body, a support table and an expansion foot. The gear-shaped forging die body is welded on the top of the support table, and a strengthening layer is electroplated on the outer surface layer of the gear-shaped forging die body. A circular groove is arranged in the gear-shaped forging die body, and limiting rods for preventing displacement during forging are welded at equal intervals on the outer side of the circular groove, and the top ends of the limiting rods penetrate through the gear-shaped forging die body. This new type of forging die can improve the overall strength and prevent displacement during forging, and is suitable for wide promotion and use.

[0004] By hitting the die cover plate, this forging die can extrude the forging raw material into the gear-shaped forging die body to achieve forging forming. However, the position of the die cover plate is not limited, and the die cover plate will displace on the gear-shaped forging die body during hammering, which is easy to damage the die and will affect the forming effect of the object.

[0005] Therefore, in order to solve the above problems, a split forging device for I-shaped precision alloy forgings is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a split forging device for I-shaped precision alloy forgings to solve the problem in the prior art mentioned in the above background technique that the forging die can extrude the forging raw material into the gear-shaped forging die body by hitting the die cover plate to achieve forging forming, but the position of the die cover plate is not limited, and the die cover plate will displace on the gear-shaped forging die body during hammering, which is easy to damage the die and will affect the forming effect of the object.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A split forging device for I-shaped precision alloy forgings, including: a base, an installation plate is installed on the top surface of the base, a die body is installed on the top surface of the installation plate, and a die cover plate is installed on the top surface of the die body;

[0008] A limiting plate is integrally formed on the side wall of the die cover plate;

[0009] A limiting structure is installed on the base. The limiting structure includes a hand-rotated worm. The hand-rotated worm is movably installed on the top surface of the base through a bearing. A fixed column is fixedly connected to the top surface of the base. A worm gear sleeve block is threadedly connected to the outer side of the lower end of the fixed column. A spring is rotatably connected to the top surface of the worm gear sleeve block. The upper end of the spring is fixedly connected to a connecting ring. A pressing rod is welded to the side wall of the connecting ring.

[0010] Preferably, the mold cover plate is adapted to the mold body, and the limiting plate is sleeved on the outer side of the upper end of the fixed column.

[0011] Preferably, the fixed column is located at the rear side of the hand-rotated worm. The upper end of the fixed column penetrates through the mounting plate and is located on both sides of the mold body.

[0012] Preferably, the worm gear sleeve block is adapted to the hand-rotated worm, and the worm gear sleeve block meshes with the hand-rotated worm.

[0013] Preferably, the spring is sleeved on the outer side of the upper end of the fixed column.

[0014] Preferably, the connecting ring is sleeved on the outer side of the mold body, and the upper end of the fixed column penetrates through the connecting ring. The top surface of the connecting ring is in contact with the bottom surface of the limiting plate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: By sleeving the limiting plate integrally formed with the mold cover plate on the fixed column fixedly connected to the base, the fixed column cooperates with the limiting plate to provide guiding and limiting for the movement of the mold cover plate above the mold body, so that the mold cover plate can only move vertically, avoiding the horizontal displacement of the mold cover plate, and further ensuring the matching effect between the mold cover plate and the mold body and the forming effect of the forging.

[0016] The utility model sets a limiting structure. The mold cover plate is covered on the top surface of the mold body, and the limiting plate is sleeved outside the fixed column. At this time, a forging hammer is used to strike the mold cover plate. The mold cover plate acts on the raw material, enabling the raw material to be formed inside the mold body, spreading the hammering force, avoiding excessive force concentration and causing cracks in the raw material. Press down the pressing rod, and the pressing rod presses down the spring through the connecting ring, causing the spring to contract and deform downward. Then release the pressing rod, and the connecting ring will reset upward under the elastic recovery of the spring. The top surface of the connecting ring will strike the bottom surface of the limiting plate, which can vibrate the mold cover plate to loosen the mold cover plate from the raw material and the mold body, facilitating the removal of the mold cover plate. Rotate the manually rotated worm. The manually rotated worm meshes with the worm gear sleeve block. The rotation of the manually rotated worm drives the rotation of the worm gear sleeve block. The worm gear sleeve block is threadedly connected to the lower end of the fixed column. When the worm gear sleeve block rotates, it will move upward at the lower end of the fixed column. The worm gear sleeve block drives the spring to move upward outside the fixed column, which can adjust the position height of the lower end of the spring outside the fixed column, and further adjust the impact force of the connecting ring on the limiting plate under the action of the spring, improving the convenience of taking and placing the mold cover plate and ensuring the use experience of the device.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 4 , an embodiment provided by the present utility model:

[0024] The base 1, the mold body 12, and the mold cover plate 13 used in this application are products that can be directly purchased on the market. Their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here.

[0025] An I-shaped precision alloy forging split forging device, comprising: a base 1, an installation plate 11 is installed on the top surface of the base 1, a mold body 12 is installed on the top surface of the installation plate 11, and a mold cover plate 13 is installed on the top surface of the mold body 12;

[0026] A limiting plate 14 is integrally formed on the side wall of the mold cover plate 13;

[0027] A limiting structure 2 is installed on the base 1. The limiting structure 2 includes a hand-rotated worm 21. The hand-rotated worm 21 is movably installed on the top surface of the base 1 through a bearing. A fixed column 22 is fixedly connected to the top surface of the base 1. A worm gear sleeve block 23 is threadedly connected to the outer side of the lower end of the fixed column 22. A spring 24 is rotatably connected to the top surface of the worm gear sleeve block 23. The upper end of the spring 24 is fixedly connected to a connecting ring 25. A pressure rod 26 is welded to the side wall of the connecting ring 25. By sleeving the limiting plate 14 integrally formed with the mold cover plate 13 on the fixed column 22 fixedly connected to the base 1, the fixed column 22 cooperates with the limiting plate 14 to guide and limit the movement of the mold cover plate 13 on the upper side of the mold body 12, so that the mold cover plate 13 can only move vertically, avoiding the horizontal displacement of the mold cover plate 13, and further ensuring the matching effect between the mold cover plate 13 and the mold body 12 and the forming effect of the forging.

[0028] Further, the mold cover plate 13 is adapted to the mold body 12. The limiting plate 14 is sleeved on the outer side of the upper end of the fixed column 22. The raw materials in the mold body 12 can be forged and formed through the mold cover plate 13. The limiting plate 14 cooperates with the fixed column 22 to guide and limit the movement of the mold cover plate 13 on the upper side of the mold body 12.

[0029] Further, the fixed column 22 is located behind the hand-rotated worm 21. The upper end of the fixed column 22 penetrates through the installation plate 11 and is located on both sides of the mold body 12. The fixed column 22 can guide and limit the mold cover plate 13 on both sides.

[0030] Further, the worm gear sleeve block 23 is adapted to the hand-rotated worm 21. The worm gear sleeve block 23 meshes with the hand-rotated worm 21. Rotating the hand-rotated worm 21 can drive the worm gear sleeve block 23 to move spirally on the fixed column 22.

[0031] Further, the spring 24 is sleeved on the outer side of the upper end of the fixed column 22. The spring 24 can deform and move on the outer side of the fixed column 22. The spring 24 provides power for the reset movement of the connecting ring 25.

[0032] Furthermore, the connecting ring 25 is sleeved outside the mold body 12, and the upper end of the fixing column 22 penetrates through the connecting ring 25. The top surface of the connecting ring 25 is in contact with the bottom surface of the limiting plate 14. The connecting ring 25 can impact the limiting plate 14 under the action of the spring 24 on the fixing column 22, so that the mold cover plate 13 is separated from the mold body 12, ensuring the convenience of disassembling and assembling the mold cover plate 13.

[0033] Working principle: During processing, the raw material is placed inside the mold body 12, and the mold cover plate 13 is covered on the top surface of the mold body 12, so that the lower end of the mold cover plate 13 contacts the raw material, and the limiting plate 14 is sleeved outside the fixing column 22. At this time, a forging hammer is used to hammer the mold cover plate 13. The mold cover plate 13 acts on the raw material, so that the raw material is formed inside the mold body 12, spreading the hammering force and avoiding excessive concentration of force, which may cause cracks in the raw material.

[0034] When it is necessary to take out the forging, the pressure rod 26 can be pressed downward. The pressure rod 26 presses the spring 24 downward through the connecting ring 25, so that the spring 24 contracts and deforms downward. Then, the pressure rod 26 is released, and the connecting ring 25 will reset upward under the elastic recovery action of the spring 24. The top surface of the connecting ring 25 will impact the bottom surface of the limiting plate 14, which can vibrate the mold cover plate 13, so that the mold cover plate 13 is loosened between the raw material and the mold body 12, facilitating the removal of the mold cover plate 13.

[0035] At the same time, by rotating the hand-rotated worm 21, the hand-rotated worm 21 meshes with the worm gear sleeve block 23. The rotation of the hand-rotated worm 21 drives the rotation of the worm gear sleeve block 23. The worm gear sleeve block 23 is threadedly connected to the lower end of the fixing column 22. When the worm gear sleeve block 23 rotates, it will move upward at the lower end of the fixing column 22. The worm gear sleeve block 23 drives the spring 24 to move upward outside the fixing column 22, and the position height of the lower end of the spring 24 outside the fixing column 22 can be adjusted. Furthermore, the impact force of the connecting ring 25 on the limiting plate 14 under the action of the spring 24 can be adjusted, so as to improve the convenience of taking and placing the mold cover plate 13 and ensure the use experience of the device.

[0036] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Any person skilled in the art can smoothly implement the present invention according to the illustrations in the specification and the above description. However, any equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above, such as slight modifications, decorations, and evolutions, are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
