Description

Technical Field

[0001] The present invention relates to the field of forging and pressing of flange ring parts, and particularly to a forging and pressing device for flange ring parts facilitating the removal of blank parts and a forging and pressing method thereof. Background Art

[0002] The forging and pressing of flange ring parts is a metal processing technology mainly used for manufacturing flange ring parts. Through mechanical operations, plastic deformation is performed on metal materials to obtain the required flange shape and size. These ring parts play an important role in connecting and sealing industrial equipment such as pipelines, valves, and pressure vessels.

[0003] For the Chinese invention patent application with the publication number CN113020513A, a flange forging device, which relates to the field of flange forging, includes an upper template, a driving rod, and a lower template. At the four corner positions on the top of the lower template, sliders are fixed. In the present invention, it is fabricated by forging a steel plate, that is, a steel plate strip with a fixed length and width is planned and cut from the whole steel plate, and then forged into a semi-circular ring by a pressing plate. Two semi-circular rings can be welded into a flange. Therefore, basically no scrap iron cuttings are generated, avoiding the situation in the past where the cuttings generated by integral cutting can only be treated as scrap iron, resulting in waste of workpiece materials. Through such a setting, labor time is saved, the production efficiency is high, and it only takes 30 seconds to press a set of flanges; the labor intensity of workers is improved, and during the production process, only the steel bar needs to be placed on the mold, and the bending of the flange can be completed through an automated program; raw materials are saved, and compared with the traditional integral cutting of steel plates, about 45% of raw materials can be saved, generating greater economic benefits.

[0004] During the processing of existing flange blank parts, since the forging method using a mold is required, the placement of the existing blank parts in the mold and their subsequent removal are both carried out manually using tools. However, when the weight and volume of the blank parts are large, after forging and pressing, it is likely to cause the situation that it is time-consuming and laborious to remove the blank parts from the mold. Moreover, since the forging and pressing is carried out by an extrusion method, during the downward movement of the upper mold, the blank parts are likely to shift, thus affecting the quality of the formed blank parts, and seriously, it may cause certain damage to the mold itself.

Detailed implementation manners

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] The present invention provides a flange ring forging device for facilitating the taking out of a blank as shown in Figure 1-12 , which includes a base 001. A hydraulic base 101 is arranged above the base 001. Guide shafts 102 are installed between the four corners of the hydraulic base 101 and the four corners of the base 001.

[0022] Furthermore, in the above structure, the pressing-down assembly 002 includes a pressing-down die 201. The pressing-down die 201 is installed below the sliding seat 104. A limiting cylinder 202 is installed below the sliding seat 104, and the limiting cylinder 202 is sleeved with the pressing-down die 201. A plurality of groups of cavities 203 are annularly distributed and opened below the sliding seat 104. A push rod 205 is slidably connected in the cavity 203. A first spring 204 is installed between the push rod 205 and the inner wall of the cavity 203. A push cylinder 206 is installed on the side of the push rod 205 away from the first spring 204, and the push cylinder 206 is slidably connected to the outside of the limiting cylinder 202.

[0023] The push rod 205 is pushed by the first spring 204, so that the position of the push cylinder 206 on the outside of the limiting cylinder 202 is maintained. And the pressing-down die 201 can move downward under the action of the sliding seat 104, so as to complete the pressing-down action. And the push cylinder 206 can limit the green body during the pressing-down process.

[0024] Furthermore, in the above structure, the demoulding assembly 003 includes a bearing seat 301. The bearing seat 301 is installed above the base 001, and the bearing seat 301 and the pressing-down die 201 are in the same vertical horizontal plane. An annular cavity 302 is opened on the side of the bearing seat 301. A die frame 303 is sleeved on the bearing seat 301. A snap ring 304 is installed on the inner wall of the die frame 303, and the snap ring 304 is slidably connected to the annular cavity 302.

[0025] Through the cooperation of the snap ring 304 and the annular cavity 302, the die frame 303 can be limited and slide on one side of the bearing seat 301. And the bearing seat 301 is used for bearing the green body, and the die frame 303 is used for shaping and limiting the forged green body.

[0026] Furthermore, in the above structure, an annular frame 305 is installed above the base 001, and the annular frame 305 is sleeved with the bearing seat 301 and the die frame 303. A plurality of groups of first hydraulic cavities 306 are annularly distributed and opened in the annular frame 305. An extrusion column 307 is connected through the first hydraulic cavity 306, and the upper part of the extrusion column 307 and the edge of the push cylinder 206 are in the same vertical horizontal plane. A plurality of groups of second hydraulic cavities 308 are annularly distributed and opened inside the base 001. A push shaft 309 is connected through the second hydraulic cavity 308, and the push shaft 309 is fixedly connected to the lower edge of the die frame 303. A hydraulic oil pipe 310 is connected and communicated between the first hydraulic cavity 306 and the second hydraulic cavity 308.

[0027] By pressing down the pushing cylinder 206, the pushing cylinder 206 can contact the extrusion column 307, and press down the extrusion column 307. There is a large amount of hydraulic oil in the first hydraulic chamber 306. At this time, the pressed-down extrusion column 307 will squeeze the hydraulic oil, causing it to enter the second hydraulic chamber 308, thereby causing the push shaft 309 to move upward. Finally, the push shaft 309 pushes the mold frame 303 to move upward, so that the mold frame 303 and the bearing seat 301 form the mold shape required for flange ring forging.

[0028] Furthermore, in the above structure, the driving assembly 004 includes a fixing plate 401, which is symmetrically installed on one side above the base 001. A motor 402 is installed on one side of the fixing plate 401, and a connecting cylinder 403 is installed at the output end of the motor 402. The openings of the two connecting cylinders 403 are arranged oppositely. A plurality of limiting grooves 404 are provided on the inner wall of the connecting cylinder 403. A push plate 405 is arranged in the connecting cylinder 403. A plurality of first teeth 406 are annularly distributed and installed on one side of the push plate 405. A plurality of limiting blocks 407 are installed at the edge of the push plate 405, and the limiting blocks 407 are slidably connected to the corresponding limiting grooves 404.

[0029] The motor 402 can drive the connecting cylinder 403 to rotate, and the cooperation between the limiting grooves 404 and the limiting blocks 407 on the connecting cylinder 403 can ensure that the push plate 405 is limited and slides in the connecting cylinder 403.

[0030] Furthermore, in the above structure, a second spring 408 is installed between the push plate 405 and the inner wall of the connecting cylinder 403. A limiting ring 409 is installed on the inner wall of the connecting cylinder 403. A first bevel gear 410 is sleeved and fixed on the connecting cylinder 4'. A first screw 411 passes through and connects between the two connecting cylinders 403. Annular grooves 412 are symmetrically provided on the first screw 411, and the annular grooves 412 are slidably connected to the corresponding limiting rings 409. A plurality of second teeth 414 are annularly distributed and installed at both ends of the first screw 411, and the second teeth 414 are in contact with the corresponding first teeth 406. A slide bar 413 is symmetrically installed between the two fixing plates 401.

[0031] Through the cooperation of the limiting ring 409 and the annular groove 412, the first screw 411 can stably rotate between the two connecting cylinders 403. And due to the limitation of the second spring 408 on the push plate 405 and the friction between the first teeth 406 and the second teeth 414, the two connecting cylinders 403 limit the first screw 411. When one of the motors 402 is driven, at this time, the connecting cylinder 403 on one side will drive the first screw 411 to rotate, and the push plate 405 inside the connecting cylinder 403 on the other side will be squeezed, thereby pushing the second spring 408, and vice versa.

[0032] Further, in the above structure, the component removal member 005 includes a connection frame 501. The connection frame 501 is disposed between two sets of fixing plates 401. An internally threaded block 502 is installed below the connection frame 501, and the internally threaded block 502 is screwed with the first screw 411. A guide plate 503 is installed between the connection frames 501, and the guide plate 503 is connected through two sets of sliding rods 413. A second screw 504 is rotatably connected above the connection frame 501. Two sets of second bevel gears 505 are oppositely installed on one side of the second screw 504, and one set of second bevel gears 505 is engaged with one set of first bevel gears 410.

[0033] Through the cooperation of the internally threaded block 502 and the first screw 411, the connection frame 501 can move between the fixing plates 401. When the connection frame 501 moves to the end of the first screw 411, the motor 402 near this side is in the working state at this time. Since the internally threaded block 502 has moved in place, the first screw 411 cannot rotate. At this time, the connection cylinder 403 will rotate by itself under the action of the push plate 405 and the second spring 408, so that the first bevel gear 410 on the connection cylinder 403 drives the second bevel gear 505 to rotate, and vice versa.

[0034] Further, in the above structure, a connection seat 506 is disposed above the connection frame 501, and the connection seat 506 is screwed with the second screw 504. Guide blocks 510 are symmetrically installed below the connection seat 506. Guide grooves 511 are symmetrically opened above the connection frame 501, and the guide grooves 511 are slidably connected with the guide blocks 510. Electromagnetic slide rails 507 are symmetrically installed on one side of the connection seat 506 away from the two sets of second bevel gears 505. An electromagnetic slide block 508 is slidably connected in the electromagnetic slide rails 507. A clamping pliers 509 is installed on one side of the electromagnetic slide block 508, and the two sets of clamping pliers 509 are oppositely arranged.

[0035] Through the drive of the first bevel gear 410 to the second bevel gear 505, the second screw 504 rotates, causing the second screw 504 to drive the connection seat 506 to move, so that the two sets of clamping pliers 509 approach the bearing seat 301. And the clamping and releasing actions of the two sets of clamping pliers 509 can be controlled through the two sets of electromagnetic slide rails 507, so as to perform the picking and placing actions on the blank.

[0036] A forging method for a flange ring part facilitating the removal of a blank, including a forging device for a flange ring part facilitating the removal of a blank as above, and the processing steps are specifically as follows: S1: The clamping pliers 509 are moved relative to each other through the electromagnetic slide rails 507, so that the blank is clamped. At this time, the first screw 411 rotates to drive the connection frame 501 to move. After the blank moves above the bearing seat 301, the clamping pliers 509 are loosened, so that the blank falls above the bearing seat 301; S2: Drive the sliding seat 104 to move downward through the hydraulic column 103, so that the lower pressing die 201 extrudes the green body, thereby making the pushing cylinder 206 contact the extrusion column 307, so that the hydraulic oil moves into the second hydraulic chamber 308, so that the pushing shaft 309 drives the die frame 303 to move upward, thereby wrapping the green body; S3: As the lower pressing die 201 continues to press downward, the green body deforms, and due to the wrapping and limiting of the die frame 303, the green body forms an annular iron cake shape, thereby obtaining the basic model of the flange ring; S4: Finally, by repeating the first step of the clamping pliers 509, the formed green body is clamped and taken out from above the bearing seat 301, thereby completing the forging work of the flange ring part.

[0037] As Figure 1-12 shown, clamp the green body with the clamping pliers 509. At this time, rotate the motor 402 on the opposite side, so that the first screw 411 drives the internally threaded block 502 to move, so that the connecting frame 501 drives the whole green body to move to the side where the motor 402 is located. When the internally threaded block 502 moves in place on the first screw 411, at this time the first screw 411 cannot rotate, but the motor 402 continues to rotate, so that the connecting cylinder 403 rotates alone. At this time, the second bevel gear 505 just meshes with the first bevel gear 410, so that the second screw 504 drives the connecting seat 506 to move, makes the clamping pliers 509 continue to move, places the green body on the bearing seat 301. After the clamping pliers 509 are reset, the hydraulic column 103 drives the lower pressing die 201 to press downward, so that the pushing cylinder 206 first contacts and extrudes the extrusion column 307, so that the pushing shaft 309 drives the die frame 303 to move upward, and as the continuous pressing, the lower pressing die 201 can extrude the green body, and the die frame 303 limits the extrusion, so that the green body can be extruded and formed. When the hydraulic column 103 drives the lower pressing die 201 to reset, at this time the first spring 204 pushes the pushing cylinder 206 to reset, and the die frame 303 resets, so that the formed green body can be exposed above the bearing seat 301, and then the formed flange green body is taken out by the clamping pliers 509, thus completing the processing of the green body. By this method, the green body can be effectively limited during the processing, avoiding the situation of position deviation during the downward pressing process, and it is convenient to take out the green body after forging, saving manpower and material resources and improving the forging efficiency.

[0038] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
