Description

Technical Field

[0001] The invention belongs to the technical field of flange forging equipment, and in particular relates to an energy-saving flange forging furnace. Background Art

[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Forged flange is a product with the best mechanical properties among flange products. Its raw material is generally a column blank. When forging flange is cast, the column blank is forged in a forging furnace and then hammered to shape, and then cut, polished and other processing procedures are performed to obtain it.

[0003] When forging a column blank, the existing flange forging furnace will put multiple column blanks in the furnace at the same time. When the temperature of the column blank reaches the casting requirement, the worker will open the furnace door and take out a column blank for hammering. However, since the existing forging furnace lacks a suitable material taking device, when the furnace door is opened, the temperature in the furnace will continue to dissipate through the opened furnace door, thereby causing the loss of heat energy in the forging furnace. In addition, since the surface of the column blank is relatively round, the speed of taking out the column blank from the forging furnace is further reduced, and then the temperature in the forging furnace is sharply lost during the entire period when the furnace door is open.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] The present invention provides Figures 1 to 9An energy-saving flange forging furnace shown in the figure comprises a base 1, a furnace body 2 is installed on the top of the base 1, a feed port and a discharge port are respectively opened on both sides of the furnace body 2, a first furnace door 3 is provided at the feed port, a second furnace door 4 is provided at the discharge port, a storage plate 5 is provided inside the furnace body 2, and the storage plate 5 is inclined downward on the side close to the discharge port, a plurality of cylindrical blanks 6 are placed on the top of the storage plate 5, a support platform 7 is hinged at the bottom of the storage plate 5, the bottom of the support platform 7 is fixedly connected to the inner wall of the bottom of the furnace body 2, and the support platform 7 is located on the side where the center of gravity of the storage plate 5 is biased toward the feed port, a first support plate 8 and a second support plate 9 are respectively provided on both sides of the support platform 7, the first support plate 8 and the second support plate 9 are both fixedly connected to the bottom of the furnace body 2, the height of the first support plate 8 is higher than the height of the second support plate 9, and the first support plate 8 is provided at a height of a second support plate 9. A support plate 8 is close to the direction of the first furnace door 3, and in the initial state, the first support plate 8 does not contact the bottom of the storage plate 5. A discharge assembly is arranged near the discharge port inside the furnace body 2. A material picking box 10 is installed on the side of the furnace body 2 near the discharge port. Both sides of the material picking box 10 are designed to be open. A material receiving assembly is arranged in the material picking box 10. A box door 11 is installed on the side of the material picking box 10 away from the furnace body 2. The first furnace door 3 and the box door 11 are respectively hinged on the side of the furnace body 2 away from the material picking box 10. A first electric push rod 12 is hinged between the front and rear sides of the first furnace door 3 and the front and rear sides of the furnace body 2. A second electric push rod 13 is hinged between the front and rear sides of the box door 11 and the front and rear sides of the material picking box 10. The front and rear sides of the second furnace door 4 are rotatably connected to the front and rear inner walls of the discharge port respectively near the top;

[0033] Before forging, the first furnace door 3 can be opened by the first electric push rod 12 when the second furnace door 4 is closed, so that the blanks 6 can be placed one by one on the top of the placing plate 5. Since the placing plate 5 is in an inclined state, when the blanks 6 fall on the top of the placing plate 5, the blanks 6 can roll along the top of the placing plate 5 to a position that conflicts with the second furnace door 4. When the blanks 6 are placed, the first furnace door 3 is closed and the furnace body 2 is started, so that all the blanks 6 on the placing plate 5 are calcined.

[0034] When the blank 6 is calcined and ready to be taken, the discharge assembly is started to move it downward gradually. During this process, as the discharge assembly moves downward, the second blank 6 can be restricted by the discharge assembly first, and the second furnace door 4 is then released. When the restriction of the second furnace door 4 is released, the first blank 6 can push open the second furnace door 4 under the action of gravity and fall onto the receiving assembly in the material taking box 10. Then the discharge assembly is closed. At this time, all the blanks 6 on the storage plate 5 can automatically move forward to the position of the previous blank 6 to wait for being taken.

[0035] Finally, the material taking box 10 is opened by the second electric push rod 13, and the blank 6 on the material receiving assembly can be removed. Compared with the existing material taking method, the material taking efficiency of the present invention is higher, and the furnace door opening and closing time is shorter, which greatly reduces the heat loss in the furnace body 2 and is more energy-saving and environmentally friendly.

[0036] like Figure 2 , Figure 3 and Figure 7 As shown, the discharge assembly includes a baffle 14, which is perpendicular to the front side of the furnace body 2, and the bottom of the baffle 14 is vertically slidable and inserted into the bottom inner wall of the furnace body 2. The baffle 14 is penetrated with through holes along the two sides thereof, and a partition 15 matching the length of the through hole is fixedly connected to the top inner wall of the through hole, and the height of the through hole is greater than the diameter of the blank 6, and the storage plate 5 is inserted into the through hole, and the top of the baffle 14 is slidably sleeved with a fixed plate 16, and the fixed plate 16 is fixedly connected to the top inner wall of the furnace body 2, and the bottom of the baffle 14 is horizontally fixedly connected with a sealing plate 17, and the bottom of the sealing plate 17 is vertically connected to the top of the base 1. A hydraulic rod 18 is fixedly connected, and a plug plate 19 is arranged in parallel on one side of the fixed plate 16 close to the second furnace door 4. The plug plate 19 is slidably inserted into the inner wall at the bottom of the discharge port, and the bottom of the plug plate 19 is vertically fixedly connected to the top of the sealing plate 17. A plug hole is provided at the bottom of the second furnace door 4, and the top of the plug plate 19 is slidably inserted into the plug hole. In the initial state, the length of the plug plate 19 inserted into the plug hole is greater than the distance from the bottom of the partition 15 to the top of the blank 6. The thickness of the bottom of the partition 15 and the top of the plug plate 19 gradually becomes thinner toward the middle, and the distance from the partition 15 to the second furnace door 4 is equal to the diameter of the blank 6.

[0037] When the first blank 6 is placed on the placing plate 5, the first blank 6 will roll along the top of the placing plate 5 to a position in contact with the second furnace door 4 under the action of gravity, and the blanks 6 subsequently placed on the placing plate 5 can be close to each other under the action of gravity;

[0038] When it is necessary to take out the blank 6, the hydraulic rod 18 is started to shorten it gradually. As the hydraulic rod 18 shortens gradually, the sealing plate 17 can drive the baffle 14 and the plug plate 19 to move downward together. In this process, as the sealing plate 17 continues to descend, the partition 15 on the baffle 14 can be inserted between the first blank 6 and the second blank 6 first, thereby restricting the second blank 6, and the plug plate 19 is gradually withdrawn from the insertion hole. As the sealing plate 17 continues to descend, when the plug plate 19 is completely withdrawn from the insertion hole at the bottom of the second furnace door 4, the hydraulic rod 18 is closed. At this time, since the second furnace door 4 is no longer restricted by the plug plate 19, the second furnace door 4 is deflected away from the storage plate 5 under the pressure of the first blank 6, so that the discharge port is opened, and the first blank 6 can roll along the top of the storage plate 5 to the material receiving assembly in the material taking box 10, thereby realizing the single material taking operation;

[0039] After the first blank 6 falls into the material taking box 10, the second furnace door 4 returns to the vertical state under the action of gravity, and the hydraulic rod 18 is started at this time, so that it drives the baffle 14 and the plug plate 19 to gradually move upward through the sealing plate 17. In this process, the plug plate 19 can be first inserted into the insertion hole at the bottom of the second furnace door 4, so as to lock the second furnace door 4. As the sealing plate 17 continues to move, when the partition 15 gradually separates from the second blank 6, the second blank 6 and other blanks 6 can move together toward the discharge port under the action of gravity. When the second blank 6 contacts the second furnace door 4, all blanks 6 stop moving, and the hydraulic rod 18 can be closed at this time. Similarly, when the second blank 6 needs to be taken, it can be achieved according to the above operation.

[0040] During the entire process of taking the blank 6, the blank 6 can be automatically transferred to the material taking box 10 by only opening and closing the second furnace door 4. Therefore, compared with the existing material taking method, the material taking efficiency of the present invention is higher and the furnace door opening and closing time is shorter, which greatly reduces the heat loss in the furnace body 2 and is more energy-saving and environmentally friendly.

[0041] like Figure 4 and Figure 5 As shown, the material receiving assembly includes a material receiving plate 20, the top surface of the material receiving plate 20 gradually tilts downward from both sides to the direction close to the middle of the material receiving plate 20 in a V shape, a plurality of telescopic rods 21 are vertically fixedly connected between the bottom of the material receiving plate 20 and the bottom inner wall of the material taking box 10, a buffer spring 22 is sleeved on the telescopic rod 21, and the two ends of the buffer spring 22 are respectively fixedly connected to the bottom of the material receiving plate 20 and the bottom inner wall of the material taking box 10, and two notches are opened on the side of the material receiving plate 20 close to the box door 11, the length of the two notches is greater than half of the width of the material receiving plate 20, and the distance between the two notches is less than the length of the blank 6;

[0042] As the second furnace door 4 is opened, the blank 6 closely attached to the second furnace door 4 can roll onto the receiving plate 20 under the action of gravity, and when the blank 6 contacts the top of the receiving plate 20, the receiving plate 20 begins to compress the telescopic rod 21 and the buffer spring 22 downward due to the pressure of the blank 6, thereby converting the impact of the blank 6 on the receiving plate 20 into the internal energy of the buffer spring 22, thereby protecting the receiving plate 20 from being damaged by the blank 6;

[0043] In addition, since the top surface of the receiving plate 20 is V-shaped, when the blank 6 falls to the top of the receiving plate 20, the V-shaped design of the top surface of the receiving plate 20 can restrict the blank 6, thereby preventing the blank 6 from rolling down from the top of the receiving plate 20;

[0044] When the blank 6 falls steadily on the top of the receiving plate 20, a forklift or lifting equipment can be used to apply a supporting force to the blank 6 from the two notches of the receiving plate 20, so as to facilitate the blank 6 to be quickly removed from the top of the receiving plate 20 for subsequent hammering operations.

[0045] like Figure 3 , Figure 8 and Fig. 9 As shown, a bevel groove is provided at the top of the storage plate 5 near the feed inlet, and the bottom groove wall of the bevel groove gradually tilts upward toward the feed inlet, and a movable block 23 is slidably installed in the bevel groove, and the top of the movable block 23 is flush with the top of the storage plate 5, and the bottom of the movable block 23 is tightly fitted with the bottom groove wall of the bevel groove, and a connecting hole is penetrated through the bottom groove wall of the bevel groove, and a limiting rod 24 is rotatably connected between the front and rear side inner walls of the connecting hole, and a connecting plate 25 is hinged at the bottom of the movable block 23, and the bottom of the connecting plate 25 is always tilted toward the feed inlet, and a first counterweight block 26 is fixedly connected to the bottom of the connecting plate 25, and the weight of the first counterweight block 26 is greater than the gravity of the movable block 23, and a strip-shaped limiting hole is penetrated through the connecting plate 25 along the front-to-back direction, and the limiting rod 24 penetrates and is inserted in the limiting hole;

[0046] In the process of placing the blank 6 onto the placement plate 5, as the blank 6 falls onto the movable block 23, the movable block 23 begins to move along the inclined groove toward the direction close to the discharge port due to the impact force of the blank 6, and as the movable block 23 moves, the movable block 23 can pull the top of the connecting plate 25 to move together, and in the process of the movement of the connecting plate 25, since the connecting plate 25 is also restricted by the limiting rod 24 and the limiting hole, while the top of the connecting plate 25 moves toward the direction close to the discharge port, the connecting plate 25 also pries the first counterweight block 26 axially with the limiting rod 24 as the axis, thereby converting the impact force of the blank 6 on the placement plate 5 into the kinetic energy of the first counterweight block 26 and the movable block 23 and the gravitational potential energy of the first counterweight block 26, thereby playing a buffering and protective role on the placement plate 5, preventing the placement plate 5 from being deformed and damaged due to the impact of the blank;

[0047] In addition, since the hinge point between the storage plate 5 and the support platform 7 is relatively close to the feed port, the side of the storage plate 5 close to the discharge port always remains tilted downward. Therefore, when the blank 6 falls onto the storage plate 5, the impact force of the blank 6 on the storage plate 5 will also cause the side of the storage plate 5 close to the discharge port to deflect upward, thereby converting the impact force of the blank 6 on the storage plate 5 into the kinetic energy of the storage plate 5. If there are other blanks 6 on the storage plate 5 when the blank 6 is placed on the storage plate 5, the impact force of the blank 6 just placed on the storage plate 5 on the storage plate 5 can be partially converted into the kinetic energy of other blanks 6 when they deflect upward with the storage plate 5 and the gravitational potential energy, thereby also having a buffering effect on the storage plate 5.

[0048] like Figure 3 , Figure 6 and Figure 7 As shown, a groove is provided on the side of the second furnace door 4 close to the storage plate 5, and a sliding groove is provided on the half of the groove wall on the side opposite to the storage plate 5, and a second counterweight block 27 is slidably installed between the front and rear groove walls of the sliding groove, and a first buffer plate 28 is vertically hingedly connected to the side of the second counterweight block 27 close to the storage plate 5, and a second buffer plate 29 is hingedly connected to the bottom of the first buffer plate 28, and the hinged part of the two is opposite to the middle part of the blank 6, and the front and rear sides of the second buffer plate 29 are respectively rotatably connected to the front and rear inner walls of the groove near the bottom;

[0049] When the blank 6 has not yet been placed into the furnace body 2, since the connection between the first buffer plate 28 and the second buffer plate 29 is not squeezed, the second counterweight 27 can be located at the bottom of the chute under the action of gravity, and the hinge between the first buffer plate 28 and the second buffer plate 29 protrudes toward the direction close to the storage plate 5;

[0050] When the blank 6 is placed on the top of the placement plate 5, the blank can roll along the top of the placement plate 5 toward the discharge port. When the blank 6 contacts the hinge of the first buffer plate 28 and the second buffer plate 29, due to the extrusion, the hinge of the first buffer plate 28 and the second buffer plate 29 can simultaneously deflect in the direction away from the placement plate 5. As the two gradually deflect, the second counterweight block 27 can move upward along the slide groove under the joint push of the first buffer plate 28 and the second buffer plate 29, thereby converting the impact force of the blank 6 on the second furnace door 4 into the kinetic energy and gravitational potential energy of the second counterweight block 27, thereby playing a buffering and protective role for the second furnace door 4, and preventing the second furnace door 4 from being damaged and deformed due to excessive impact force.

[0051] like Figure 4 and Figure 5As shown, a collecting hole is provided at the bottom of the material taking box 10, and a collecting plate 30 is provided at the bottom of the collecting hole. The front side view of the collecting plate 30 is an isosceles triangle. A plurality of tie rods 31 are vertically fixedly connected between the top middle position of the collecting plate 30 and the bottom of the material receiving plate 20, and in the initial state, the collecting plate 30 can close the collecting hole under the pulling of the tie rods 31, and a collecting box 32 is provided at the bottom of the collecting hole, and the collecting box 32 is placed on the top of the base 1, and the top opening of the collecting box 32 is larger than the bottom area of ​​the collecting plate 30, and a plurality of leakage holes are provided through the top of the material receiving plate 20, and the plurality of leakage holes are evenly distributed on the top of the material receiving plate 20;

[0052] During the forging process of the billet 6, as the temperature increases, some impurities in the billet 6 will precipitate onto the surface of the billet 6 under the action of high temperature, and when the billet 6 rolls along the top of the placing plate 5 through the second furnace door 4 to the receiving plate 20, the impurities on the surface of the billet 6 will be separated from the surface of the billet 6 due to vibration, and the separated impurities will fall to the top of the collecting plate 30 through the gap and the leak hole of the receiving plate 20, and when the billet 6 falls on the top of the receiving plate 20, the receiving plate 20 will drive the collecting plate 30 to move downward through the pull rod 31 under the pressure of the billet 6, and as the collecting plate 30 moves downward, the top of the collecting plate 30 is gradually separated from the collecting hole, so that the impurities gathered on the top of the collecting plate 30 can fall along the inclined surface of the top of the collecting plate 30 into the collecting box 32 and be collected, thereby avoiding the impurities precipitated on the surface of the billet 6 from the furnace body 2 to the forging place. Falling randomly and causing ground pollution.

[0053] like Figure 3 As shown, a connecting strip 33 is fixedly connected to one side of the bottom of the discharge port near the storage plate 5, and the side of the connecting strip 33 opposite to the storage plate 5 is designed with an inclined surface, and the two inclined surfaces of the connecting strip 33 and the storage plate 5 fit tightly, and in the initial state, the top surface of the connecting strip 33, the top surface of the storage plate 5 and the bottom inner wall of the discharge port are all located on the same plane;
