Description

Technical Field

[0001] The present invention relates to the field of flange forging equipment, and more specifically, to a forging device for processing high-strength flange pipe seats. Background Art

[0002] In the field of industrial production, as a key connecting component, flange pipe seats are widely used in many industries such as petroleum, chemical industry, electric power, and machinery manufacturing. Their main function is to achieve the connection between pipelines and between pipelines and equipment, and at the same time, they have to withstand various complex working conditions such as pressure, temperature, and medium corrosion in the pipeline system. Therefore, there are extremely high requirements for their strength, precision, and quality.

[0003] Forging process, as an important means of manufacturing high-strength flange pipe seats, can apply pressure to the metal blank to cause plastic deformation, thereby improving the internal organizational structure of the metal and enhancing its mechanical properties. However, there are many problems in the existing forging devices for processing high-strength flange pipe seats in actual applications.

[0004] Firstly, when most existing forging devices perform forging operations, the rising and falling processes of the forging hammer rely on a driving device to provide power. For example, common hydraulic drive or motor drive methods, in the entire forging process, the driving device continuously works, not only consuming a large amount of electrical energy or hydraulic energy, but also causing the equipment to heat up during long-term operation, further increasing energy loss. Secondly, the inconvenient adjustment of forging pressure is another prominent problem of most existing forging devices. In actual production, high-strength flange pipe seats of different specifications and materials require different forging pressures to ensure their quality and performance, but the existing forging devices often have difficulty in flexibly adjusting the forging pressure. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a forging device for processing high-strength flange pipe seats.

[0018] The beneficial effects of the present invention are:

[0019] The forging hammer structure in the present invention is controlled by the lifting hammer structure when rising, and relies on gravity during the descending process. No additional power equipment is required to drive it during the descending forging process, which reduces the use time of the lifting hammer structure, reduces the energy consumption of the entire forging process, and helps to achieve energy-saving production and reduce production costs. In addition, the present invention can adjust the forging pressure according to the height of the forging hammer structure controlled by the lifting hammer structure.

When the forging hammer structure slides upward to a preset position and contacts and cooperates with the two hammer release structures, the two hammer release structures control the lifting hammer structure to separate from the forging hammer structure, and can accurately control the timing of the separation of the forging hammer structure from the lifting hammer structure, thereby ensuring that the height and speed of the forging hammer falling during each forging are relatively stable, achieving accurate control of the forging effect, and improving the consistency and quality stability of the forged products.

[0040] Embodiment 1

[0041] Please refer to Figure 1-15 , a forging device for processing high-strength flange pipe seats provided by the present invention, including: a hammer frame structure 2, a forging table structure 3 and a hammer lifting structure 4 installed on the base 1; a forging hammer structure 5 slidably disposed on the hammer frame structure 2 is connected to the hammer lifting structure 4 to slide upward in the hammer frame structure 2 under the control of the hammer lifting structure 4; two hammer releasing structures 6 connected to the hammer lifting structure 4 are installed on the hammer frame structure 2. When the forging hammer structure 5 slides upward to a preset position and comes into contact and cooperation with the two hammer releasing structures 6, the two hammer releasing structures 6 control the separation of the hammer lifting structure 4 and the forging hammer structure 5, so that the forging hammer structure 5 falls under the action of gravity to perform forging treatment on the forging blank placed on the forging table structure 3

[0042] The working principle and technical effects of the above solution are as follows:

[0043] When the forging device of the present invention is forging, the forging blank to be processed is placed on the forging table structure 3, and the hammer lifting structure 4 starts to work. The hammer lifting structure 4 is connected to the forging hammer structure 5. Under the control of the hammer lifting structure 4, the forging hammer structure 5 slides upward along the hammer frame structure 2. The hammer frame structure 2 provides a stable track and support for the upward movement of the forging hammer structure 5, ensuring a smooth upward process and an accurate direction. As the forging hammer structure 5 rises, gravitational potential energy is gradually accumulated. The higher the rising height, the greater the stored gravitational potential energy. When the forging hammer structure 5 slides upward to the preset position, the forging hammer structure 5 comes into contact and cooperation with two hammer releasing structures 6 installed on the hammer frame structure 2. The preset position is set in advance according to the required forging pressure and process requirements. Different forging requirements correspond to different preset positions. The hammer releasing structure 6 is connected to the hammer lifting structure 4. When the forging hammer structure 5 slides upward to the preset position and comes into contact and cooperation with the two hammer releasing structures 6, the two hammer releasing structures 6 control the separation of the hammer lifting structure 4 and the forging hammer structure 5. After the hammer lifting structure 4 and the forging hammer structure 5 are separated, the forging hammer structure 5 is only affected by gravity and starts to accelerate downward in the hammer frame structure 2. During the downward movement, the stored gravitational potential energy is gradually converted into kinetic energy, and the speed continuously increases. The forging hammer structure 5 impacts the forging blank placed on the forging table structure 3 at a certain speed, applying a strong pressure to it, causing the forging blank to undergo plastic deformation, thereby realizing the forging process of the high-strength flange pipe seat. The forging table structure 3 provides stable support for the forging blank, ensuring the smooth progress of the forging process. After one forging is completed, the control hammer lifting structure 4 and the forging hammer structure 5 are connected again, and the above processes of lifting the hammer, releasing the hammer, and forging are repeated until the forging blank meets the required shape, size, and performance requirements. In the present invention, the forging hammer structure 5 is controlled by the hammer lifting structure during the upward movement and relies on gravity during the downward movement, reducing the energy consumption of the hammer lifting structure 4, contributing to energy-saving production and reducing production costs. Using the conversion of gravitational potential energy into kinetic energy to achieve forging makes the energy more effectively utilized. The hammer lifting structure 4 lifts the forging hammer structure 5 to a certain height, storing gravitational potential energy, and this part of the potential energy is converted into kinetic energy for forging when the hammer is released. Compared with the method of continuously relying on the driving device to provide power, the energy conversion is more direct and efficient. And the forging pressure can be adjusted according to the height that the hammer lifting structure 4 controls the forging hammer structure 5 to rise. The higher the rising height, the greater the gravitational potential energy of the forging hammer when it falls, and the greater the forging pressure generated after being converted into kinetic energy, enabling the forging device to flexibly adapt to the forging requirements of high-strength flange pipe seats with different specifications and quality requirements, improving the versatility and applicability of the device.

[0044] Embodiment 2

[0045] Please refer toFigure 1-15 In a forging device for processing high-strength flange pipe seats provided by the present invention, the forging table structure 3 includes: a wear-resistant tabletop 301 disposed directly below the forging hammer structure 5. The bottom of the wear-resistant tabletop 301 is connected to a support 303 that slides on four columns 302. The four columns 302 are fixedly connected to the base 1, and a tension spring is fixedly connected between the base 1 and the support 303. One end of the support 303 is hinged to an inclined beam 304, and the other end of the inclined beam 304 is hinged to a sliding seat 306 screwed onto a horizontal lead screw 305. A screw for pressing against the horizontal lead screw 305 is screwed onto the sliding seat 306. The horizontal lead screw 305 is rotatably provided on the base 1 through two rod seats.

[0046] The working principle and technical effects of the above solution are as follows:

[0047] When the forging device of the present invention is forging, after placing the forging blank to be processed on the wear-resistant tabletop 301 of the forging table structure 3, the wear-resistant tabletop 301 is controlled to rise to lift the forging hammer structure 5, so that the lifted movement height of the forging hammer structure 5 is the same as the height that the forging blank to be processed needs to be forged. The purpose is that when the forging hammer structure 5 is forged and returns to the initial height, it can be judged that the forging of the forging blank meets the preset requirements; in the present invention, by lifting the wear-resistant tabletop so that the movement height of the forging hammer is the same as the height that the blank needs to be forged, the preset forging requirements can be accurately achieved; judging the forging completion by the forging hammer structure 5 returning to the initial height, the method is intuitive, simple, and convenient for operation and monitoring;

[0048] When adjusting the horizontal height of the wear-resistant tabletop 301, after placing the forging blank to be processed on the wear-resistant tabletop 301, the horizontal lead screw 305 is controlled to rotate, changing the threaded connection position between the horizontal lead screw 305 and the sliding seat 306, thereby driving the sliding seat 306 to slide on the upper surface of the base 1, so that one end of the sliding seat 306 drives the inclined beam 304 to move, and the other end of the inclined beam 304 drives the support 303 to slide on the four columns 302, thereby adjusting the horizontal height of the wear-resistant tabletop 301 on the support 303. A tension spring is fixedly connected between the base 1 and the support 303, which is beneficial to ensuring the stability during forging after the horizontal height of the wear-resistant tabletop 301 is adjusted; a screw for pressing against the horizontal lead screw 305 is screwed onto the sliding seat 306 to prevent the horizontal lead screw 305 from rotating under external force, further improving the invariability of the height position of the wear-resistant tabletop 301 during forging.

[0049] Example 3

[0050] Please refer to Figure 1-15, the hammer frame structure 2 includes: an equipment frame 201 fixedly connected to the base 1, a guiding frame 202 fixedly connected to the front side of the equipment frame 201, and a central slideway of the forging hammer structure 5 longitudinally sliding in the guiding frame 202; two assembly frames 203 for installing two hammer placing structures 6 are fixedly connected to the front side of the guiding frame 202. The forging hammer structure 5 includes: a hammer cylinder mechanism 7, with a hammer block connected to the bottom of the hammer cylinder mechanism 7; two traction blocks 8 for clamping and cooperating with the hammer lifting structure 4 are provided on both sides of the top of the hammer cylinder mechanism 7; pressing contact slopes with a gradually decreasing horizontal height from inside to outside are provided above the outer sides of the two traction blocks 8; the front side of the hammer cylinder mechanism 7 is connected to a conduit mechanism 9 sliding in the limiting slideway on the front side of the guiding frame 202; a guiding block 10 cooperatively arranged with the hammer placing structure 6 is connected to the conduit mechanism 9. A clamping groove is provided below the outer side of the traction block 8.

[0051] The working principle and technical effects of the above solution are as follows:

[0052] Two traction blocks 8 for clamping and cooperating with the hammer lifting structure 4 are provided on both sides of the top of the hammer cylinder mechanism 7; when the hammer lifting structure 4 is clamped and cooperated at the bottom of the two traction blocks 8, the connection with the forging hammer structure 5 is realized, and the hammer cylinder mechanism 7 can be driven to slide upward in the central slideway of the guiding frame 202. When the hammer cylinder mechanism 7 slides, it drives the conduit mechanism 9 to slide upward in the limiting slideway on the front side of the guiding frame 202. The conduit mechanism 9 can prevent the hammer cylinder mechanism 7 from rotating and ensure the stability of its lifting movement. When it slides to a preset distance, the guiding block 10 on the conduit mechanism 9 contacts and cooperates with the hammer placing structure 6. At this time, the hammer placing structure 6 can be controlled to separate the hammer lifting structure 4 from the two traction blocks 8, and the hammer cylinder mechanism 7 falls under its own gravity, so as to perform forging treatment through the hammer block at the bottom of the hammer cylinder mechanism 7. A clamping groove is provided below the outer side of the traction block 8, which can improve the stability when the two traction blocks 8 are clamped and cooperated with the hammer lifting structure 4.

[0053] Embodiment 4

[0054] Please refer to Figure 1-15, the hammer barrel mechanism 7 includes: an adjustable hammer barrel 701, two traction blocks 8 are fixedly connected to the upper sides of both sides of the adjustable hammer barrel 701, a hammer block is fixedly connected to the bottom of the adjustable hammer barrel 701, and a detachable end cover 702 is screwed to the top of the adjustable hammer barrel 701; a detection shaft 703 slidably arranged in the central hole of the detachable end cover 702 is connected to a sealing disc 704 hermetically slidably arranged in the cavity of the adjustable hammer barrel 701, and a tension compression spring 705 sleeved on the detection shaft 703 is located between the detachable end cover 702 and the sealing disc 704; a conduit mechanism 9 is fixedly connected to the front side of the adjustable hammer barrel 701, and the connection position of the conduit mechanism 9 and the adjustable hammer barrel 701 is located between the inner wall limit protrusion 706 of the adjustable hammer barrel 701 and the inner bottom surface of the adjustable hammer barrel 701; the sealing disc 704 is clamped above the limit protrusion 706 to ensure a stable injection area is formed between the sealing disc 704 and the inner bottom surface of the adjustable hammer barrel 701. The conduit mechanism 9 includes: a fixed conduit 901 fixedly connected to the adjustable hammer barrel 701 and a moving conduit 902 hermetically rotatably arranged in the fixed conduit 901, the fixed conduit 901 is slidably arranged in the limit slideway on the front side of the guiding frame 202, the moving conduit 902 is connected to a straight pipe 904 with a one-way input valve through a right-angle pipe 903, and a discharge pipe 905 fixedly connected to the straight pipe 904 is located between the one-way input valve and the right-angle pipe 903; a pipe plug is threadedly and hermetically connected to the discharge pipe 905; the straight pipe 904 is slidably arranged in the longitudinal hole of the pipe rack 906, and the pipe rack 906 is connected to the assembly rack 203 through a plurality of bolts.

[0055] The working principle and technical effects of the above solution are as follows: The structure of the hammer cylinder mechanism 7 is arranged such that its overall weight can be adjusted. Adjusting the weight of the hammer cylinder mechanism 7 can change the forging impact pressure on the forging blank under its own gravity, so as to meet the forging pressure requirements in different situations. During adjustment, the discharge pipe 905 is connected to the liquid pump, and liquid is injected into the discharge pipe 905 through the liquid pump. The liquid flows unidirectionally into the right-angle pipe 903 through the one-way input valve, and enters the adjustable hammer cylinder 701 through the right-angle pipe 903, the moving conduit 902, and the fixed conduit 901. The liquid entering the adjustable hammer cylinder 701 generates an upward pressure on the sealing disk 704, causing the sealing disk 704 to slide upward in the adjustable hammer cylinder 701 and drive the detection shaft 703 to slide upward. Scale lines are provided on the detection shaft 703, and the volume of the liquid injected into it can be judged according to the preset scale lines, which is convenient for calculating the overall weight of the hammer cylinder mechanism 7, so as to adjust according to the preset requirements. The tension compression spring 705 sleeved on the detection shaft 703 is located between the detachable end cover 702 and the sealing disk 704, which is convenient for ensuring the accuracy of the filled liquid and reducing the probability of liquid sloshing during downward movement for forging; the setting of the conduit mechanism 9 is not only convenient for injecting liquid but also for discharging liquid. During discharge, the control pipe rack 906 is separated from the assembly rack 203 through multiple bolts. At this time, the straight pipe 904 can be rotated downward, and the straight pipe 904 drives the moving conduit 902 to rotate relative to the fixed conduit 901 through the right-angle pipe 903. When the straight pipe 904 is set downward, the pipe plug on the discharge pipe 905 can be removed to discharge the liquid; Heat exchange coolant can also be filled in the adjustable hammer cylinder 701, so as to absorb the heat generated during the forging of the hammer block to a certain extent. During the forging process of the hammer block, a large amount of heat will be generated due to the violent impact and friction with the forging blank. Continuous high temperature will reduce the performance of the hammer block material and cause thermal fatigue. The heat exchange coolant absorbs the heat of the hammer block, which can effectively reduce the temperature of the hammer block, reduce the generation of thermal fatigue damage, ensure the dimensional accuracy and shape accuracy of the hammer block, and thus improve the quality of the forging product.

[0056] Example 4

[0057] Please refer to Figure 1-15 , the hammer lifting structure 4 includes: a hammer lifting cylinder 401 fixedly connected to the base 1. The movable end of the hammer lifting cylinder 401 is connected to the rear end of the hammer lifting frame 402. The two inserting plates 403 at the front end of the hammer lifting frame 402 are slidably fitted in the horizontal sockets at the top of the two hammer lifting suspension plates 404. At the upper ends of the inner sides of the two hammer lifting suspension plates 404, hammer lifting clamping blocks 405 are fixedly connected. Below the two hammer lifting clamping blocks 405, there are downward pressing slopes 406 for abutting and cooperating with the pressing slopes of the traction clamping block 8; above the two hammer lifting clamping blocks 405, there is a clamping plane for clamping below the traction clamping block 8.

[0058] The vertical surfaces on the left and right sides of the guiding block 10 are in sliding fit with the inner surfaces of the two mounting frames 203, and the two crimping inclined surfaces at the top of the guiding block 10 are arranged in cooperation with the two hammer placing structures 6.

[0059] The hammer placing structure 6 includes: a height-adjusting screw 601 rotatably arranged on the side of the guiding frame 202 through a screw base, a height-adjusting sleeve 602 screwed in the middle of the height-adjusting screw 601, and a screw for abutting against the height-adjusting screw 601 screwed on the height-adjusting sleeve 602; the height-adjusting sleeve 602 is connected to a rectangular sliding sleeve 604 slidably arranged in the longitudinal slideway of the mounting frame 203 through a rear slider 603 slidably arranged in the rear slot of the mounting frame 203; a rectangular vertical pipe 605 is slidably connected in the rectangular sliding sleeve 604, and one end of the rectangular vertical pipe 605 close to the guiding block 10 is connected to a telescopic slider 606 slidably arranged in the side opening of the rectangular sliding sleeve 604 and the inner chute of the guiding frame 202, and the telescopic slider 606 is arranged in cooperation with the crimping inclined surface of the guiding block 10; the other end of the rectangular vertical pipe 605 away from the guiding block 10 is connected to the inner wall of the rectangular sliding sleeve 604 through a plurality of compression springs 607; a hammer placing frame 609 is fixedly connected to the top of a rectangular vertical rod 608 slidably arranged in the rectangular vertical pipe 605, and a hammer lifting hanging plate 404 is slidably arranged in the longitudinal hole of the hammer placing frame 609; a plurality of balance rods 610 fixedly connected to the side of the rectangular vertical rod 608 are slidably arranged in the balance holes on the side of the mounting frame 203; the connecting end of the hammer lifting block 405 and the hammer lifting hanging plate 404 is in clamping contact with the upper surface of the hammer placing frame 609.

[0060] The working principle and technical effects of the above solution are as follows:

[0061] After the lifting hammer cylinder 401 is started, it can drive the lifting hammer frame 402 to move in the up and down directions. When the lifting hammer frame 402 moves upward, it can drive the two lifting hammer suspension plates 404 to move upward through the two inserting plates 403. When the two lifting hammer suspension plates 404 move upward, they drive the two lifting hammer clamping blocks 405 to move upward. When the two lifting hammer clamping blocks 405 move upward, they can drive the two traction clamping blocks 8 to move upward, so as to realize the control of the upward movement of the adjustable hammer barrel 701. When the adjustable hammer barrel 701 moves upward, it drives the guiding block 10 to move upward through the fixed conduit 901. The vertical surfaces on the left and right sides of the guiding block 10 are slidably matched with the inner sides of the two assembling frames 203 to ensure the stability of the up and down sliding of the guiding block 10. When the two pressing inclined surfaces at the top of the guiding block 10 move to contact and cooperate with the telescopic sliders 606 of the two hammer releasing structures 6, as the guiding block 10 continues to move upward, a top pressure can be generated on the telescopic sliders 606, so that the telescopic sliders 606 slide into the rectangular sliding sleeve 604. At this time, the telescopic sliders 606 drive the rectangular vertical pipe 605 to slide in the rectangular sliding sleeve 604 and compress the multiple compression springs 607. When the rectangular vertical pipe 605 moves, it drives the rectangular vertical rod 608 to move away from the guiding block 10. The rectangular vertical rod 608 drives the lifting hammer suspension plate 404 to move away from the traction clamping block 8 through the hammer releasing frame 609, and the lifting hammer suspension plate 404 slides on the inserting plate 403. When the vertical surfaces on the left and right sides of the guiding block 10 contact the telescopic sliders 606, after the lifting hammer suspension plate 404 drives the lifting hammer clamping block 405 to disengage from the traction clamping block 8, the adjustable hammer barrel 701 can fall under its own gravity to perform forging treatment. After forging, structures such as the rectangular vertical pipe 605, the rectangular vertical rod 608, the hammer releasing frame 609, and the lifting hammer suspension plate 404 are reset under the action of the multiple compression springs 607. After completing one forging, it is necessary to control the two lifting hammer clamping blocks 405 to be re-engaged and cooperated with the two traction clamping blocks 8. At this time, control the lifting hammer cylinder 401 to drive the lifting hammer frame 402 to move downward. When the lifting hammer frame 402 moves downward, it can drive the two lifting hammer suspension plates 404 to move downward through the two inserting plates 403. When the two lifting hammer suspension plates 404 move downward, they drive the two lifting hammer clamping blocks 405 to move downward. When the two lifting hammer clamping blocks 405 move downward, the downward pressing inclined surfaces 406 below the two lifting hammer clamping blocks 405 contact the pressing inclined surfaces of the traction clamping blocks 8, and under the cooperation of the two inclined surfaces, the two lifting hammer clamping blocks 405 move outward, finally compressing the multiple compression springs 607. When moving to the preset position, the clamping planes of the two lifting hammer clamping blocks 405 are re-held in the state of being clamped below the traction clamping blocks 8 under the elastic force of the multiple compression springs 607, facilitating the next forging work.

[0062] At the lower ends on the inner sides of two mounting frames 203, a reinforcing beam 11 is fixedly connected, and the top of the reinforcing beam 11 is connected to a pressure sensor through an elastic pad; when the fixed conduit 901 contacts the bottom of the limiting slideway on the front side of the guiding frame 202, the lower surface of the guiding block 10 contacts and cooperates with the pressure sensor. When the pressure sensor detects the guiding block 10, it indicates that the forging has been completed, and the staff is timely reminded to stop the forging work to ensure the forging effect.
