Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a circular flanging hydraulic mold. Background Technology

[0002] In the metal processing industry, flanging is a common processing method for round parts. Flanging can increase the strength of parts and change their shape to meet different application requirements. However, existing round flanging dies have some shortcomings in practical use.

[0003] For example, after some molds are finished flanging, the parts need to be manually removed from the mold. This not only increases the labor intensity but also reduces the production efficiency. At the same time, there are certain safety hazards in the manual removal process. In addition, some molds are not precise enough in positioning round parts, and they are prone to shaking during flanging, resulting in low dimensional accuracy of the flanged parts and affecting product quality. Therefore, a circular flanging hydraulic mold is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a circular flanging hydraulic mold to solve the problems mentioned in the background art.

[0005] The circular flanging hydraulic mold provided in this application adopts the following technical solution:

[0006] A circular flanging hydraulic mold includes a lower mold base and an upper mold base. A positioning block is fixedly connected to the top middle outer wall of the lower mold base, and a flanging block is fixedly connected to the bottom outer wall of the upper mold base. A demolding mechanism is installed on the outer wall of the flanging block. The demolding mechanism includes multiple mounting blocks fixedly connected to the circumferential outer wall of the flanging block. The multiple mounting blocks are evenly distributed in a circumferential array with equal spacing. A demolding rod is rotatably connected to the outer wall of the mounting blocks through a rotating shaft. The bottom end of the demolding rod is arc-shaped. A compression spring is fixedly connected to the outer wall of the demolding rod near the top end. The end of the compression spring away from the demolding rod is fixedly connected to the outer wall of the flanging block.

[0007] A circular part is sleeved on the outer wall of the positioning block, and multiple arc-shaped inner support plates are embedded in the outer wall of the positioning block. The outer walls of the multiple arc-shaped inner support plates are in contact with the inner wall of the circular part. A clamping mechanism for driving the multiple circular parts to expand outward synchronously is installed on the top inner wall of the lower mold base.

[0008] Preferably, the clamping mechanism includes a shaped turntable rotatably connected to the inner wall of the top center of the lower mold base, with connecting rods rotatably connected to multiple ends of the shaped turntable, a connecting block rotatably connected to the end of the connecting rod away from the shaped turntable, and a sliding column fixedly connected to the top outer wall of the connecting block.

[0009] Preferably, the outer wall of the lower mold base is provided with multiple straight grooves, which are evenly distributed in a circular array with equal spacing around the positioning block. The sliding column is slidably connected to the inner wall of the straight groove, and its top end is fixedly connected to the circular part.

[0010] Preferably, a servo motor is fixedly installed on the inner wall of the bottom center of the lower mold base, and the end of the output shaft of the servo motor is fixedly connected to the outer wall of the center of the irregular turntable.

[0011] Preferably, the top outer wall of the lower mold base is fixedly connected to a plurality of guide rods, the upper mold base is slidably connected to the outer wall of the plurality of guide rods, and a connector is fixedly connected to the top middle outer wall of the upper mold base.

[0012] Preferably, a return spring is sleeved on the outer wall of the guide rod, the top end of the return spring is fixedly connected to the outer wall of the upper mold base, and its bottom end is fixedly connected to the top outer wall of the lower mold base.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The demolding mechanism of this circular flanging hydraulic mold is ingeniously designed. The demolding process requires no manual intervention. The demolding rod and the compression spring work together to automatically lift the circular part from the positioning block after flanging. This greatly reduces labor intensity, avoids damage to parts caused by manual demolding, and significantly improves demolding efficiency and product yield. It is especially suitable for mass production and greatly improves overall production efficiency.

[0015] 2. By incorporating a synchronously outwardly supporting arc-shaped inner support plate and a clamping mechanism consisting of a servo motor, a shaped turntable, connecting rods, connecting blocks, and sliding columns, precise positioning and secure clamping of round parts of different specifications can be achieved. The servo motor drives the shaped turntable to rotate, which in turn drives the arc-shaped inner support plate to synchronously outwardly support itself through the connecting rods and other components. This ensures that the arc-shaped inner support plate fits tightly against the inner wall of the round part, preventing displacement of the part during the flanging process. This provides a stable and reliable foundation for flanging, effectively improving the accuracy and product quality of the flanging process. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a circular flanging hydraulic mold. (Refer to...) Figure 1-5 A circular flanging hydraulic mold includes a lower mold base 1 and an upper mold base 2. A positioning block 3 is fixedly connected to the top middle outer wall of the lower mold base 1, and a flanging block 4 is fixedly connected to the bottom outer wall of the upper mold base 2. A demolding mechanism is installed on the outer wall of the flanging block 4. The demolding mechanism includes multiple mounting blocks 12 fixedly connected to the circumferential outer wall of the flanging block 4. The multiple mounting blocks 12 are evenly distributed in a circumferential array with equal spacing. A demolding rod 13 is rotatably connected to the outer wall of each mounting block 12 via a rotating shaft. The bottom end of the demolding rod 13 is arc-shaped. This arc-shaped design can... The edge of the circular part 18 can be easily inserted between the demolding rod 13 and the flange block 4, facilitating demolding. A compression spring 14 is fixedly connected to the outer wall of the demolding rod 13 near the top. The end of the compression spring 14 away from the demolding rod 13 is fixedly connected to the outer wall of the flange block 4. The function of the compression spring 14 is to provide a certain elastic support force for the demolding rod 13. During the demolding process, the compression spring 14 can make the demolding rod 13 contact the circular part 18 better and apply an appropriate demolding force, ensuring that the circular part 18 can be smoothly removed from the mold.

[0024] A circular part 18 is sleeved on the outer wall of the positioning block 3. Multiple arc-shaped inner support plates 7 are embedded in the outer wall of the positioning block 3. The outer walls of the multiple arc-shaped inner support plates 7 are in contact with the inner walls of the circular part 18. A clamping mechanism is installed on the top inner wall of the upper mold base 2 to drive the multiple arc-shaped inner support plates 7 to support outwards synchronously. The clamping mechanism includes an irregularly shaped turntable 10 rotatably connected to the middle inner wall of the top of the upper mold base 2. Multiple ends of the irregularly shaped turntable 10 are rotatably connected to connecting rods 9. The end of the connecting rod 9 away from the irregularly shaped turntable 10 is rotatably connected to a connecting block 8. A sliding column 6 is fixedly connected to the top outer wall of the connecting block 8.

[0025] The outer wall of the upper mold base 2 has multiple straight grooves 5, which are evenly distributed in a circular array around the positioning block 3 at equal intervals. The sliding column 6 is slidably connected to the inner wall of the straight groove 5, and its top end is fixedly connected to the arc-shaped inner support plate 7. A servo motor 11 is fixedly installed on the inner wall of the bottom center of the upper mold base 2. The end of the output shaft of the servo motor 11 is fixedly connected to the outer wall of the center of the irregular turntable 10. When it is necessary to clamp and position the circular part 18, the servo motor 11 is started. The servo motor 11 drives the irregular turntable 10 to rotate. The irregular turntable 10 drives the connecting block 8 to move through the connecting rod 9. The connecting block 8 then drives the sliding column 6 to slide in the straight groove 5. The sliding of the sliding column 6 drives the arc-shaped inner support plate 7 to expand outward synchronously, so that the arc-shaped inner support plate 7 is tightly attached to the inner wall of the circular part 18, realizing the precise positioning and firm clamping of the circular part 18.

[0026] Multiple guide rods 16 are fixedly connected to the top outer wall of the upper mold base 2. The lower mold base 1 is slidably connected to the outer wall of the multiple guide rods 16. A connector 15 is fixedly connected to the top middle outer wall of the lower mold base 1. The connector 15 can connect the upper mold base 2 to the output end of an external hydraulic device. A return spring 17 is sleeved on the outer wall of the guide rods 16. The top end of the return spring 17 is fixedly connected to the outer wall of the lower mold base 1, and its bottom end is fixedly connected to the top outer wall of the upper mold base 2. The setting of the return spring 17 can ensure that the lower mold base 1 can move stably up and down along the guide rods 16 during operation. After the flanging work is completed, the lower mold base 1 is assisted to return to its original position by the elastic force of the return spring 17, which improves the working efficiency and stability of the mold.

[0027] The implementation principle of a circular flanged hydraulic mold in this application embodiment is as follows: First, the circular part 18 is sleeved on the positioning block 3. The servo motor 11 is started. The servo motor 11 drives the irregular turntable 10 to rotate. The irregular turntable 10 drives the connecting block 8 to move through the connecting rod 9. The connecting block 8 then drives the sliding column 6 to slide in the straight groove 5. The sliding of the sliding column 6 drives the arc-shaped inner support plate 7 to simultaneously support the outer side, so that the arc-shaped inner support plate 7 is tightly attached to the inner wall of the circular part 18, thereby achieving precise positioning and firm clamping of the circular part 18.

[0028] Then, the upper mold base 2 moves downward under the action of an external hydraulic drive device (not shown in the figure, but a conventional hydraulic drive structure), and the flange block 4 descends accordingly. When the flange block 4 descends, it drives multiple demolding rods 13 to descend. Due to the arc-shaped design of the bottom end of the demolding rod 13, the edge of the circular part 18 can be easily inserted between the demolding rod 13 and the flange block 4. At this time, multiple compression springs 14 generate elastic force, causing the demolding rod 13 to rotate around the pivot on the mounting block 12. The bottom ends of the multiple demolding rods 13 support the edge of the circular part 18, and as the... The continuous downward pressure of the flanging block 4 causes the top edge of the circular part 18 to bend and expand outward. When the edge of the circular part 18 expands and flips outward, it creates an inclined angle with the original circumferential outer wall, which makes it easier for the multiple demolding rods 13 to better hook and hold the bent and flanged edge of the circular part 18. After the flanging block 4 has finished punching and flanging the circular part 18, the upper mold base 2 rises. Through the elastic force of the multiple compression springs 14 on the multiple demolding rods 13, the circular part 18 can be easily lifted upward and demolded from the positioning block 3.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
