Technical Field

[0001] This utility model belongs to the field of forging tooling technology, and in particular relates to a forging tooling for N06625 pipe flanges. Background Technology

[0002] N06625 pipe is a corrosion-resistant alloy pipe with nickel as the base material and containing elements such as chromium, molybdenum, and niobium. It is suitable for use in harsh environments such as high temperature and strong corrosion, and has good resistance to oxidation, pitting corrosion, and crevice corrosion. It is widely used in chemical, marine, and energy fields. N06625 pipe flanges are flange components made of N06625 alloy and are used to connect N06625 pipes or other equipment. They have similar high temperature resistance and corrosion resistance to the alloy pipe and are suitable for pipeline system connections under various harsh working conditions. The forging tooling is a special tool device used for forging N06625 pipe flanges. It can be adapted to the characteristics of this alloy material and realizes the forging process of the material through appropriate structural design to meet the forming requirements of the flange.

[0003] However, existing forging fixtures are difficult to position the round bar billet during use to ensure that it is in the center of the lower die. This results in uneven stress on the billet during forging, causing problems such as inconsistent thickness and skewed shape in the forgings, which affects the dimensional accuracy and appearance quality of the flange.

[0018] The positioning part 2 includes a positioning component 21, which is disposed above the top plate 112; and a mounting component 22, which is mounted on the top plate 112. The positioning component 21 includes a ring 211 disposed above the rectangular base plate 111. The ring 211 has a plurality of sliding grooves 212 inside, and positioning blocks 213 penetrate through the inner walls of the sliding grooves 212. The positioning blocks 213 are slidably connected to the inner walls of the sliding grooves 212 respectively. A ring spring 214 is sleeved on the outer wall of the ring 211. The ring 211 is provided with several sliding members; the annular spring 214 has elastic force under normal conditions; the mounting assembly 22 includes several mounting rods 221 fixedly connected to the top of the top plate 112, and mounting blocks 222 are slidably connected to the outer walls of the mounting rods 221; the mounting blocks 222 are fixedly connected to the connecting members; the cooperation between the mounting blocks 222 and the mounting rods 221 is used to position the positioning part 2; the sliding members include several limiting blocks 215 fixedly connected to the top of the ring 211. Each of the positioning blocks 213 has an L-shaped slide rod 216 fixedly connected to its top. The side of each L-shaped slide rod 216 away from the positioning blocks 213 passes through a limiting block 215, and the L-shaped slide rods 216 are slidably connected to the limiting blocks 215. The limiting blocks 215 are arranged in a circular array around a ring 211. The connecting components include a support frame 223 fixedly connected to the outer wall of each mounting block 222, and a number of connecting frames 224 fixedly connected to the bottom of the support frame 223. The bottoms of several connecting brackets 224 are fixedly connected to the ring 211. The connecting brackets 224 are arranged in a circumferential array on the ring 211. By setting the positioning part 2, the round bar blank can be quickly positioned at the center of the lower mold 322 through the cooperation of the positioning block 213, the ring spring 214 and other structures, ensuring that the blank is subjected to uniform force, reducing problems such as uneven forging thickness and skewed shape, improving the dimensional accuracy and appearance quality of the flange, and avoiding damage to the mold due to excessive local force, thus reducing the difficulty and cost of subsequent processing.

[0019] The molding section 3 includes a drive assembly 31 mounted on top of a rectangular base plate 111; and a molding assembly 32 disposed on the drive assembly 31. The drive assembly 31 drives the molding assembly 32, which is used for molding. The drive assembly 31 includes an L-shaped support plate 311 fixedly connected to the top of the rectangular base plate 111, and an electric telescopic rod 312 fixedly connected to the top of the L-shaped support plate 311. The electric telescopic rod 312 provides power output. The molding assembly 32 includes components fixedly connected to... The upper mold 321 on the output shaft of the electric telescopic rod 312 is fixedly connected to the bottom of the top plate 112, and the lower mold 322 is fixedly connected to it. The diameter of the upper mold 321 is the same as the inner diameter of the lower mold 322. By setting the forming part 3, after positioning, the positioning block 213 and the operator's hand can be removed to avoid interference or safety hazards during forging. At the same time, the electric telescopic rod 312 drives the upper mold 321 and the lower mold 322 to cooperate in stamping, ensuring that the round bar blank is accurately formed into a disc shape, improving the safety of forging and the consistency of the finished product.

[0020] A specific application of this embodiment is as follows: In use, first, the cylindrical billet to be forged is placed into the lower mold 322. Then, the support frame 223 is held in hand, and several mounting blocks 222 are inserted onto several mounting rods 221 respectively. At this time, the cylindrical billet is located between several positioning blocks 213. Then, the support frame 223 is pushed downwards, causing the positioning blocks 213 to move downwards simultaneously. If the diameter of the cylindrical billet is larger than the inner diameter between the positioning blocks 213, the positioning blocks 213 will move away from each other and press against the annular spring 214, causing it to stretch. At this time, the elastic force of the annular spring 214 increases and acts on the positioning blocks 213, causing the positioning blocks 213 to initially... Finally, the blank is pressed tightly against the cylindrical blank to complete its positioning. During this process, the L-shaped slide bar 216 and the limiting block 215 cooperate to guide the movement of the positioning block 213. After the cylindrical blank is positioned, the worker holds the cylindrical blank and pulls the support frame 223 upward until the positioning block 213 is detached from the cylindrical blank. After detachment, the worker's hand is also removed from the cylindrical blank. Then, the electric telescopic rod 312 on the L-shaped support plate 311 is activated to drive the upper mold 321 downward to stamp the cylindrical blank. During this process, the upper mold 321 cooperates with the lower mold 322 to ensure that the flat cylindrical blank can be stamped into a disc shape.
