[0002] Neck flange is a common pipe connection structure, usually used in pipeline systems. Its main feature is that it has a protruding neck on the outer circumference of the flange. During the forging process of this flange, a red-hot cylindrical blank is usually placed in a neck die, and the forging blank is continuously struck by the forging top die to form the required forging.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a flange processing and forging device, which has the following beneficial effects:

[0024] 1. The present invention drives the first gear to rotate by driving a motor. The eccentric groove on the first gear first drives the eccentric slide seat to slide to the right through the transmission pin until the first ring cover and the friction wheel are frictionally fitted. At this time, the forging die is located above the outer edge of the blank. The second gear is rotated by the meshing transmission of the first gear, driving the friction wheel to rotate. The friction wheel then drives the flange neck die and the top surface blank to rotate. The outer edge part is evenly hammered forged by the forging die. After the eccentric groove rotates one circle, the blank is moved to its original position. By using the above structure, the mold is automatically moved to a position deviating from the bottom of the forging die, and the blank is driven to rotate. With a certain hammering frequency of the forging die, the forging blank can be evenly hammered, thereby improving the effect of blank forming, and the operation is simple.

[0025] 2. The present invention contracts the first telescopic drive rod to make the first ring cover and the second ring cover engage with each other, and cooperates with the die barrel and the forging die to put the blank in a sealed environment. The heat dissipated by the blank itself is sealed and insulated, which reduces heat loss, thereby reducing the temperature difference effect on the surface of the blank, and improving the forging quality of the flange blank to a certain extent.

[0026] 3. The present invention circulates the gas in the heat transfer protection component through an air pump and sprays it obliquely through a chip removal nozzle. At the same time, the third gear is driven to rotate by driving motor 2, and the third gear is engaged with the chip cleaning gear ring to rotate the chip removal nozzle, so that the jet airflow itself directly acts on the waste chips and generates centrifugal force on the waste chips, thereby cleaning the waste chips from the top surface of the flange neck mold, thereby reducing the waste chips between the flange plate mold and the blank, and further improving the quality of the neck flange forging.

[0027] 4. The present invention accumulates the waste chips between the first ring cover and the flange neck mold and scrapes them to the top of the chip removal groove through the fixed scraper. At the same time, the fixed scraper is squeezed along the inclined surface of the ladder frame to drive the chip removal plate to rotate downward. At this time, the waste chips slide along the surface of the chip removal plate to the top surface of the eccentric slide. After the fixed scraper passes through the ladder frame, the reset spring resets and rebounds to make the chip removal plate flush with the top surface of the chip removal chassis, so that the heat transfer protection component continues to be sealed, and then the waste chips are discharged from the surface of the eccentric slide for cleaning. The above structure is used to automatically discharge the waste chips between the first ring cover and the flange neck mold, avoiding the accumulation of waste chips in the first ring cover to generate large dust.

[0052] The heat transfer prevention component 5 is arranged on the chip removal chassis 3, the flange neck mold 4 is fixedly connected to the heat transfer prevention component 5, and the flange neck mold 4 is located in the heat transfer prevention component 5;

[0053] A forging die 6, which is arranged on the top of the heat transfer protection component 5;

[0054] Among them, the flange neck mold 4 is used for flange neck molding, and the flange plate mold 43 is used for flange plate molding; the first telescopic driving rod 42 can drive the flange plate mold 43 to rise and fall, which is convenient for cleaning the oxidized waste forged from the surface of the blank before molding, thereby improving the quality of flange forging, and can also expose the blank part after forging to the outside, without pouring the blank out of the mold, thereby facilitating the removal of the blank; the flange plate mold 43 rises after the blank has been forged for a period of time, which can make the distance between the blank and the flange plate mold 43 smaller, thereby reducing waste chips falling into the flange plate mold 43.

[0055] Preferably, the eccentric groove 23 is a combination of a sector shape and a V-shape, and the V-shaped segment opens outward, and the number of teeth of the first gear 22 is greater than the number of teeth of the second gear 28;

[0056] Specifically, the V-shaped portion of the eccentric groove 23 is used to drive the eccentric slide 24 to slide back and forth, and the fan-shaped segment is used to keep the eccentric slide 24 deviated from the bottom of the forging die 6; after the eccentric slide 24 slides to the right until the anti-heat transfer component 5 contacts the friction wheel 210, the friction wheel 210 can drive the flange neck die 4, the anti-heat transfer component 5 and the blank to rotate synchronously, so that the forging die 6 can evenly hammer the outer edge of the blank.

[0057] Preferably, when the flange mold 43 is retracted into the hidden annular groove 41 , the top surface of the flange mold 43 is flush with the top surface of the flange neck mold 4 .

[0058] For further example 2, please refer to Figure 6 As shown:

[0059] The heat transfer prevention component 5 includes a first ring cover 51, the bottom surface of the first ring cover 51 is in contact with the top surface of the chip removal chassis 3, a second telescopic driving rod 52 is embedded and installed inside the first ring cover 51, the top of the second telescopic driving rod 52 is fixedly connected to the second ring cover 53, the side wall of the second ring cover 53 is provided with an inner view transparent plate 54, the top of the second ring cover 53 is slidably connected to a slide plate 55, the sliding direction of the slide plate 55 is parallel to the sliding direction of the eccentric slide seat 24, and the slide plate 55 can always keep the top of the second ring cover 53 airtight, the middle part of the slide plate 55 is rotatably connected to a mold barrel 56, the inner wall of the mold barrel 56 is provided with a second slide groove 57, the top of the side wall of the forging die 6 is fixedly connected to a slider 61, the slider 61 can slide up and down along the inner surface of the second slide groove 57, the forging die 6 is movably inserted in the mold barrel 56, the bottom of the inner wall of the first ring cover 51 is fixedly connected to a fixed scraper 58, and the end of the fixed scraper 58 away from the first ring cover 51 is fixedly connected to the flange neck mold 4;

[0060] When the first ring cover 51 and the second ring cover 53 are combined, a closed space is formed to insulate the blank, thereby ensuring that the surface temperature of the blank is uniform when the forging environment temperature is low, improving the quality of flange forging, and preventing forging waste chips from splashing and scalding the workers;

[0061] When the forging die 6 is in use, it is connected to the vertical hammer hydraulic system. Through the arrangement of the slide plate 55 and the die cylinder 56, the forging die 6 is always kept in the original position to perform hammer forging vertically up and down during the process of the first ring cover 51 moving to the right.

[0062] By extending the second telescopic driving rod 52, the first ring cover 51 and the second ring cover 53 can be separated, so as to facilitate the placement of the blank and the removal of the flange forging;

[0063] By providing the internal viewing transparent plate 54, the staff can observe the forging of the neck flange.

[0064] Preferably, the first ring cover 51 and the second ring cover 53 are concentric and have the same radius, and the surfaces of the first ring cover 51, the second ring cover 53, the slide plate 55 and the mold cylinder 56 are all provided with a heat insulation layer.

[0065] For further example 3, please refer to Figure 3 and Figure 7 As shown:

[0066] An in-mold chip removal component 7 is provided on the flange neck mold 4, and the in-mold chip removal component 7 includes a chip cleaning tooth ring 71, which is concentrically rotatably connected to the top of the flange neck mold 4, and the flange plate mold 43 is located in the middle of the chip cleaning tooth ring 71, and a plurality of air pumps 72 are evenly circumferentially arranged on the top surface of the chip cleaning tooth ring 71, and the output end of the air pump 72 is fixedly connected to a chip removal nozzle 73, and the side wall of the flange neck mold 4 is fixedly connected to a side plate 74, and a driving motor 2 75 is fixedly connected to the side plate 74, and the output end of the driving motor 2 75 is fixedly connected to a third gear 76, and the chip cleaning tooth ring 71 is meshed with the third gear 76.

[0067] Preferably, the direction of the airflow sprayed by the chip removal nozzle 73 forms an angle with the diameter of the chip cleaning gear ring 71 .

[0068] Specifically, the air pump 72 is used to make the chip removal nozzle 73 spray airflow to clean the waste chips. The airflow rotates and sprays obliquely to drive the waste chips to generate a certain centrifugal force, so as to remove the waste chips on the surface of the flange neck mold 4. In addition, as the billet is forged, its diameter gradually increases, and the airflow is sprayed to the billet surface and rebounds, so that the waste chips can also be blown off from the top surface of the flange neck mold 4.

[0069] The air pump 72 and the chip removal nozzle 73 are both provided with filters to prevent waste chips from affecting their use.

[0070] For further example 4, please refer to Figure 6 and Figure 8 As shown:

[0071] An out-of-mold chip removal component 8 is provided on one side of the chip removal chassis 3, and the out-of-mold chip removal component 8 includes a chip removal groove 81 opened on one side of the chip removal chassis 3, and the top of the chip removal groove 81 is rotatably connected to a chip removal plate 82, and a return spring 83 is provided between the bottom surface of the chip removal plate 82 and the bottom surface of the chip removal groove 81, and the top surface of the return spring 83 is fixedly connected to a ladder frame 84, and the bottom surface of the fixed scraper 58 is in contact with the top surface of the chip removal chassis 3.

[0072] Preferably, the top surface of the chip removal plate 82 can be flush with the top surface of the chip removal chassis 3 through the elastic force of the reset spring 83, and the middle part of the ladder frame 84 is hollow.

[0073] Specifically, as the first ring cover 51 and the flange neck mold 4 rotate, the fixed scraper 58 accumulates the waste chips along the top surface of the chip removal chassis 3 and pushes them to the chip removal groove 81. The fixed scraper 58 squeezes the ladder frame 84 to drive the chip removal plate 82 to rotate downward, and the waste chips slide down along the chip removal plate 82 to the top surface of the eccentric slide 24, thereby automatically discharging the waste chips in the first ring cover 51, avoiding the accumulation of waste chips in the first ring cover 51 and generating large dust.

[0074] Everything in the above example works like this:

[0075] When in use, the hammer hydraulic system drives the forging die 6 to vertically hammer forge the blank. As the forging progresses, the blank gradually flattens and its diameter increases. Then, the first telescopic driving rod 42 is extended to extend the flange plate die 43 from the hidden ring groove 41, and then the driving motor 21 drives the first gear 22 to rotate. The eccentric groove 23 on the first gear 22 first drives the eccentric slide 24 to slide to the right through the transmission pin 25 until the first ring cover 51 and the friction wheel 210 are frictionally fitted. At this time, the forging die 6 is located above the outer edge of the blank, and the second gear 28 is rotated by the meshing transmission of the first gear 22, driving the friction wheel 210 to rotate, and then the friction wheel 210 frictionally drives the flange neck die 4 and the top surface blank to rotate, and the outer edge part is evenly hammered and forged by the forging die 6. After the eccentric groove 23 rotates one circle, the blank is moved to its original position;

[0076] In cold weather, during the forging process of the neck flange, the first telescopic driving rod 42 contracts, so that the first ring cover 51 and the second ring cover 53 are buckled together, and the die barrel 56 and the forging die 6 are matched to put the blank in a sealed environment. The heat dissipated by the blank itself is sealed and insulated, reducing heat loss, thereby reducing the temperature difference on the surface of the blank, and improving the forging quality of the flange blank to a certain extent;

[0077] Before the flange plate die 43 is raised, as the blank is forged, oxidized waste chips are forged off the surface of the flange neck die 4, and the gas in the heat transfer protection component 5 is circulated by the air pump 72 and obliquely sprayed through the chip removal nozzle 73. At the same time, the third gear 76 is driven to rotate by the second driving motor 75, and then the third gear 76 is meshed with the transmission chip cleaning gear ring 71 to rotate the chip removal nozzle 73, so that the jet airflow itself directly acts on the waste chips and generates centrifugal force on the waste chips, so that the waste chips are cleaned from the top surface of the flange neck die 4;

[0078] While the friction wheel 210 drives the first ring cover 51 to rotate, the waste chips between the first ring cover 51 and the flange neck mold 4 are accumulated and scraped to the top of the chip removal groove 81 through the fixed scraper 58. At the same time, the fixed scraper 58 is squeezed along the inclined surface of the ladder frame 84, driving the chip removal plate 82 to rotate downward. At this time, the waste chips slide along the surface of the chip removal plate 82 to the top surface of the eccentric slide 24. After the fixed scraper 58 passes the ladder frame 84, the reset spring 83 resets and rebounds, so that the chip removal plate 82 is flush with the top surface of the chip removal chassis 3, so that the heat transfer protection component 5 continues to remain sealed, and then the waste chips on the surface of the eccentric slide 24 are discharged and cleaned.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
