Description

Technical Field

[0001] This utility model belongs to the field of forging equipment, and in particular to an upsetting device and its oxide scale collection mechanism. Background Technology

[0002] Upsetting is a common forging process, primarily used to increase the cross-sectional area and reduce the height of a billet. This process is typically used to improve material properties or to manufacture parts requiring a large cross-sectional area, such as shafts, gears, and flanges. During upsetting, the billet is first heated to the required forging temperature. During forging, a support base holds the billet, and a forging head applies axial pressure to the billet, causing it to thicken. Because the billet temperature is high during upsetting, an oxide scale forms on its surface when it encounters oxygen in the air. This oxide scale breaks off and falls onto the support base during upsetting; however, due to its high temperature, manual collection is inefficient.

[0003] Utility model patent application number CN202022903178.0 discloses an automatic oxide scale cleaning device for upsetting in a forging press. In the upsetting process, a heated cylindrical alloy billet is first placed on the lower upsetting anvil within the mold for upsetting. The press slide is operated so that the upper upsetting anvil presses downwards onto the billet, causing the outer surface of the billet to expand and deform. At this time, the oxide scale generated by the high temperature begins to fall off. The fallen oxide scale falls along the gap between the lower upsetting anvil and the mold to the lower part of the mold. The driver is then activated, pushing the rack in a reciprocating linear motion. The rack drives the meshing gear to reciprocate, thereby pushing the oxide scale cleaning disc to reciprocate. The oxide scale accumulated between the lower upsetting anvil and the mold continuously falls into four inclined grooves on the oxide scale cleaning disc 22. When the four inclined grooves connect with four material discharge channels on the worktable, the oxide scale slides from the material discharge channels into the oxide scale collection box. This device is suitable for die upsetting processes but not for free upsetting processes. Furthermore, since the oxide scale is usually in flake form and difficult to break into powder, it cannot guarantee that all the oxide scale can pass through the gap between the upsetting anvil and the die. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a roughing device and its oxide scale collection mechanism, which is suitable for free roughing process and can automatically collect the oxide scale generated during the roughing process.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: an oxide scale collection mechanism, including a support platform, a vertical lower anvil provided on the support platform, a frustum-shaped guide post provided at the bottom of the lower anvil, the upper end diameter of the guide post being the same as the diameter of the lower anvil, the lower end diameter of the guide post being larger than the upper end diameter of the guide post, and an annular collection groove provided below the lower end of the guide post.

[0006] Furthermore, the lower anvil is fixedly connected to the guide column, and the guide column can be detachably installed on the support platform.

[0007] Furthermore, the support platform is provided with a positioning seat, the lower surface of the guide column is provided with multiple vertical positioning pins, and the upper surface of the positioning seat is provided with multiple vertical pin holes, with each positioning pin inserted into one pin hole.

[0008] Furthermore, the collection trough is rotatably mounted on the support platform, and the collection trough is connected to a drive mechanism for driving the collection trough to rotate; the bottom of the collection trough is provided with an upper discharge hole, and the support platform is provided with a lower discharge hole. When the collection trough rotates, the upper discharge hole can move to directly above the lower discharge hole; a fixed baffle plate is provided in the collection trough above the lower discharge hole.

[0009] Furthermore, a connecting rod is provided on the top of the baffle plate, and the connecting rod is installed on the support platform via a column.

[0010] Furthermore, the driving mechanism includes a motor, a driving gear is provided on the main shaft of the motor, and a driven gear is provided on the outer wall of the collection tank, the driven gear meshing with the driving gear.

[0011] Furthermore, there are three upper unloading holes.

[0012] The roughing device of this utility model includes the above-mentioned oxide scale collection mechanism.

[0013] Furthermore, an upper anvil is provided above the lower anvil, and a pressure mechanism is connected to the upper anvil.

[0014] The beneficial effects of this utility model are as follows: During the upsetting process, the heated columnar billet is placed vertically on the upper surface of the lower anvil, and then downward pressure is applied to the columnar billet. During the upsetting process, the oxide scale on the surface of the columnar billet falls off, and some of the oxide scale falls onto the guide column and slides down the surface of the guide column into the collection tank, thereby realizing the collection of oxide scale.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] The oxide scale collection mechanism of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a support platform 1, on which a vertical lower anvil 2 is provided. A frustum-shaped guide post 3 is provided at the bottom of the lower anvil 2. The upper diameter of the guide post 3 is the same as the diameter of the lower anvil 2, and the lower diameter of the guide post 3 is larger than the upper diameter of the guide post 3. An annular collection groove 4 is provided below the lower end of the guide post 3.

[0023] The support platform 1 is horizontally positioned and made of high-compressive-strength metal sheet. The lower anvil 2, a cylindrical metal column, supports the billet being uptaken. The diameter of the lower anvil 2 matches the diameter of the billet after uptaking, ensuring stable support during the uptaking process. The collection trough 4 has an annular collection cavity, with the lower end of the guide column 3's outer wall positioned above the collection cavity, ensuring that oxide scale sliding down the guide column 3's outer wall falls into the collection trough 4.

[0024] The oxide scale collection mechanism of this invention operates as follows: After heating the billet, it is placed vertically on the upper surface of the lower anvil 2. Downward pressure is then applied to the billet, causing its length to decrease and its diameter to increase. During the upsetting process, the oxide scale on the billet surface cracks and falls downwards. Some of the oxide scale falls onto the outer wall of the guide column 3 and then slides down along the outer wall of the guide column 3 into the collection tank 4. While some oxide scale falls onto the upper surface of the lower anvil 2, as the billet thickens and expands radially, it pushes the oxide scale on the upper surface of the lower anvil 2 onto the guide column 3.

[0025] The lower anvil 2 is fixedly connected to the guide post 3; specifically, the lower anvil 2 and the guide post 3 can be integrally formed. The guide post 3 is detachably installed on the support platform 1. When upsetting billets of different diameters, lower anvils 2 of different sizes can be replaced. For lower anvils 2 of different diameters, the lower end diameter of the guide post 3 below them remains consistent, ensuring that after replacing different guide posts 3 and lower anvils 2, the oxide scale can slide down along the outer wall of the guide post 3 into the collection tank 4.

[0026] The guide post 3 can be connected to the support platform 1 via common connectors such as screws. In a preferred embodiment, the support platform 1 is provided with a positioning seat 5, and the lower surface of the guide post 3 is provided with multiple vertical positioning pins 6. The upper surface of the positioning seat 5 is provided with multiple vertical pin holes, and each positioning pin 6 is inserted into one pin hole. When installing the guide post 3 and the lower anvil 2, simply align each positioning pin 6 with the pin holes and lower the guide post 3 onto the positioning seat 5. The assembly and disassembly are very convenient.

[0027] The collection tank 4 can be a rectangular or circular ring, as long as it can receive the oxide scale that slides off the outer wall of the guide column 3. The collection tank 4 can be fixedly installed on the support platform 1, and the oxide scale inside the collection tank 4 can be manually cleaned periodically. Alternatively, the collection tank 4 can be detachably installed on the support platform 1, and the collection tank 4 can be removed periodically to empty the oxide scale inside.

[0028] To achieve automatic cleaning of oxide scale in the collection tank 4, the collection tank 4 of this invention is annular in shape and rotatably mounted on the support platform 1. The collection tank 4 is connected to a drive mechanism that rotates it. Specifically, the positioning seat 5 can be a cylindrical body, with the collection tank 4 surrounding it and capable of rotating around it. The bottom of the collection tank 4 is provided with an upper discharge hole 7, which can be one, but preferably multiple, such as two, three, or four. The support platform 1 is provided with a lower discharge hole 8, the shape and size of which are the same as those of the upper discharge hole 7. When the collection tank 4 rotates, the upper discharge hole 7 can move to directly above the lower discharge hole 8, causing them to overlap. A fixed baffle plate 9 is provided inside the collection tank 4 above the lower discharge hole 8. The bottom edge of the baffle plate 9 is close to the bottom wall of the inner cavity of the collection tank 4, and the two sides of the baffle plate 9 are close to the side walls of the inner cavity of the collection tank 4.

[0029] During the roughing process, the drive mechanism rotates the collection tank 4. After the oxide scale falls into the collection tank 4, it moves along with it. When the upper discharge hole 7 and the lower discharge hole 8 are misaligned, the bottom wall of the collection tank 4 covers the lower discharge hole 8, preventing the oxide scale in the collection tank 4 from falling into the lower discharge hole 8. However, the oxide scale is blocked by the baffle plate 9 and remains above the lower discharge hole 8. When the upper discharge hole 7 moves to the lower discharge hole 8, the upper discharge hole 7 and the lower discharge hole 8 connect, allowing the oxide scale accumulated above the lower discharge hole 8 to fall through the upper discharge hole 7 into the lower discharge hole 8, and then through the lower discharge hole 8 to fall below the support platform 1. A set of support feet can be installed on the lower surface of the support platform 1 to maintain a suitable height. An oxide scale collection box can also be placed below the lower discharge hole 8 to collect the falling oxide scale.

[0030] This novel invention enables automated collection of oxide scale, eliminating the need for manual collection, reducing the risk of burns to workers, and lowering labor intensity.

[0031] The baffle plate 9 needs to be kept fixed. Specifically, a connecting rod 10 is provided on the top of the baffle plate 9, and the connecting rod 10 is installed on the support platform 1 via a column 11. The column 11 is fixed on the support platform 1, the connecting rod 10 is fixed on the top of the support platform 1, one end of the connecting rod 10 extends above the inner cavity of the collection tank 4, the upper end of the baffle plate 9 is fixedly connected to the connecting rod 10, and the lower part of the baffle plate 9 is located in the inner cavity of the collection tank 4.

[0032] In this invention, the driving mechanism includes a motor 12, which is mounted on a support platform 1. A drive gear 13 is mounted on the main shaft of the motor 12, and a driven gear 14 is mounted on the outer wall of the collection tank 4. The driven gear 14 meshes with the drive gear 13. When the motor 12 drives the drive gear 13 to rotate, it can drive the driven gear 14 to rotate, which in turn drives the collection tank 4 to rotate.

[0033] The roughing device of this utility model, such as Figure 4 As shown, including the above Figures 1 to 3 The oxide scale collection mechanism shown.

[0034] Specifically, an upper anvil 15 is provided above the lower anvil 2. The diameter of the upper anvil 15 can be larger than the diameter of the billet and the lower anvil 2, allowing for forging of billets of various diameters. The upper anvil 15 is connected to a pressure mechanism 16, which uses an existing hydraulic mechanism to push the upper anvil 15 downward and apply downward pressure to the billet.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
