Description

Technical Field

[0001] The utility model relates to the technical field of flange processing and manufacturing, in particular to a titanium flange alignment punching device. Background Art

[0002] In the production of flanges, it is usually necessary to process the center of the flange into a ring. The existing production process usually adopts a press forming method.

[0003] At present, an existing flange stamping forming device (such as patent number: CN208083146U) discloses a flange stamping forming device, including a base, and also including: a workbench fixed on the base, the workbench protrudes upward to form a cylindrical boss; a lower die, located above the workbench, the lower die is sleeved on the outer peripheral side of the boss and can move up and down, and the lower die is provided with a circle of annular grooves surrounding the outer peripheral side of the boss and used to place the flange; an upper die, located above the lower die and can move up and down, and the bottom of the upper die is provided with a groove corresponding to the boss. The utility model operates smoothly, with low noise, and will not affect the physical and mental health of workers. The utility model can limit and fix the flange by setting an annular groove on the lower die, avoiding the movement of the flange during operation, and does not need to be manually supported or pressed on the flange. On the one hand, it will not affect the personal safety of workers, and on the other hand, it ensures the accuracy of operation.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. The existing device uses a single punching device, which has a sufficient punching effect on iron flanges. However, there are lighter and stronger titanium flanges on the market. Titanium flanges are extremely strong, and a single punching device is not very effective on titanium flanges. Therefore, the application scope of the device is small. In addition, a fixing device is not set between the mold of the device and the workbench. During the flange production and stamping process, a large vibration will be generated, which may displace the mold, resulting in defects in the flange product or even damage to the mold due to incorrect stamping position.

[0006] 2. The existing device does not have a lifting device for the flange after production. After the flange is produced, it needs to be taken out manually. However, sometimes the flange will be stuck with the mold body due to excessive stamping force or its own material characteristics, making it difficult to remove. In addition, the edges and corners of the stamped flange are not polished, and removing it may cause injury. Utility Model Content

The bottom surface of the mold fixing mechanism 4 is also provided with a circular groove 408, and a through hole 407 is provided at the central axis of the circular groove 408. The through hole 407 penetrates the fixed base 401. The top surface of the fixed base 401 is provided with two slide grooves 405, and a slider is slidably connected in the slide groove 405. The slider is fixedly connected to the limit plate 403, and the fixed The fixed base 401 is installed with a limit plate 403 at both ends fixedly installed with a threaded fixing sleeve 402, and a fixing bolt 404 is sleeved inside the threaded fixing sleeve 402. A fixing groove 406 is opened at the center of the top surface of the fixed base 401, and a through hole 407 is opened at the central axis of the fixing groove 406. This solves the technical problems that the existing device does not have a structure for fixing the flange mold, which easily leads to defects in flange production and even damage to the mold, and the flange produced by the device is not easy to pick up, delaying production work and posing a risk of injury during use.

[0035] There are two fixing sets 304 , and the fixing sets 304 and the protruding portion of the telescopic piston of the secondary ram cylinder 302 are equal in height.

[0036] The diameter of the telescopic piston of the cylinder 303 is smaller than the through hole 407, so that the cylinder 303 can extend out of the through hole 407 to push out the flange.

[0037] The main stamping cylinder 2 and the stamping mechanism assembly 3 are located on the same central axis. The upper and lower stamping devices are extremely powerful and are used to stamp flanges made of some special materials.

[0038] A shock-absorbing gasket is arranged in the middle section of the fixing bolt 404 . The number of the threaded fixing sleeve 402 and the number of the fixing bolt 404 are both six. The number of the limiting plates 403 is two. The two limiting plates 403 are used to clamp the mold.

[0039] There are four springs 5 ​​and four limit links 501 , which are installed at the four corners of the stamping mechanism assembly 3 and the mold fixing mechanism 4 . Being arranged at the corners is beneficial to stabilizing the overall structure.

[0040] The flange mold is placed between the two limit plates 403 of the mold fixing mechanism 4, and the fixing groove 406 is used to fix the central axis of the mold to prevent deviation, and then the fixing bolt 404 is used to clamp the limit plate 403 to fix the mold and facilitate mold replacement. The mold fixing mechanism 4 uses a fixed mounting sleeve 409 to be sleeved and fixed on the telescopic piston of the auxiliary stamping cylinder 302.

[0041] After fixing and adjusting the mold, start the main stamping cylinder 2 to drive the upper mold 201 to descend, and start the auxiliary stamping cylinder 302 to drive the mold fixing mechanism 4 to rise. The upper and lower stamping devices work at the same time to generate huge force to stamp the flange. After the stamping is completed, the auxiliary stamping cylinder 302 retracts and closes. After closing the auxiliary stamping cylinder 302, start the cylinder 303, and the telescopic piston of the cylinder 303 extends through the through hole 407 to push out the stamped flange for workers to take. This solves the technical problems that the existing device does not have a structure for fixing the flange mold, which can easily lead to defects in flange production and even damage to the mold, and the flange produced by the device is not easy to take, delaying production work and posing a risk of injury during use.

[0042] Working principle:

[0043] The first step is to place the flange mold between the two limit plates 403 of the mold fixing mechanism 4, use the fixing groove 406 to fix the central axis of the mold to prevent displacement, and then use the fixing bolt 404 to clamp the limit plate 403 to fix the mold and facilitate mold replacement. The mold fixing mechanism 4 uses a fixed mounting sleeve 409 to be fixed on the telescopic piston of the auxiliary stamping cylinder 302. The half groove 410 opened on the fixed mounting sleeve 409 is socketed with the fixed kit 304 to achieve stable socket connection between the stamping mechanism assembly 3 and the mold fixing mechanism 4, and the springs 5 ​​fixedly connected to the four corners of the mold fixing mechanism 4 and the stamping mechanism assembly 3 also play a fixing role.

[0044] In the second step, after fixing and adjusting the mold, start the main stamping cylinder 2 to drive the upper mold 201 to descend, and start the auxiliary stamping cylinder 302 to drive the mold fixing mechanism 4 to rise. The upper and lower stamping devices work at the same time, generating huge force to stamp the flange into shape. After the stamping is completed, the auxiliary stamping cylinder 302 retracts and closes. After closing the auxiliary stamping cylinder 302, start the cylinder 303, and the telescopic piston of the cylinder 303 extends through the through hole 407 to push out the stamped flange for the convenience of workers to take.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
