Description

Technical Field

[0001] The present invention relates to the technical field of forging, and particularly to an integrated forging heating device for forging production and a using method thereof. Background Art

[0002] Forging is a common process in the machining process. In order to achieve certain characteristics, workpieces need to be forged at high temperature to obtain such properties. A forging heating furnace is an indispensable processing equipment in forging. A forging heating furnace is the main heating equipment for heating forgings in a forging workshop. At present, the combustion heating methods of forging heating furnaces are mainly coal heating, diesel heating, natural gas heating, electric heating, etc.

[0003] At present, during the heating process of bar metals by the existing forging heating furnace, the material inlet needs to be frequently opened for loading and unloading materials. When the material inlet of the heating furnace is opened, the temperature in the furnace chamber decreases due to the entry of external air, resulting in waste of heat, increasing the operating cost of the forging heating furnace and the forging heating time. At the same time, after multiple bars are pushed into the heating furnace in a straight line, the bars are in close contact with each other, so that the heated temperature at the contact places between the bars is slower than other positions of the bars, and the heating is uneven, resulting in uneven deformation of the subsequent forged bars, affecting the forming quality of the product. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to provide an integrated forging heating device for forging production and a using method thereof.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0013] Preferably, the heat dissipation prevention mechanism includes a door panel part slidably arranged on the forging heating furnace. A groove matching with the conveying rack is formed at the bottom of the door panel part. The door panel part includes a first door panel, a second door panel, a third door panel and a fourth door panel arranged in sequence. Support plates are arranged on both sides of the forging heating furnace. A hydraulic cylinder is arranged on each support plate. The piston rods of the two hydraulic cylinders are both connected with a connecting plate. One of the connecting plates is connected with the first door panel and the third door panel, and the other connecting plate is connected with the second door panel and the fourth door panel.

[0014] Preferably, a preheating cavity is formed between the first door panel and the second door panel, a heating cavity is formed between the second door panel and the third door panel. A distance adjusting component is arranged in the heating cavity. A blanking cavity is formed between the third door panel and the fourth door panel.

[0015] Preferably, the distance adjusting component includes a fixing plate fixedly arranged in the heating cavity. A screw rod is rotatably connected to the fixing plate. A sleeve part is arranged on the outer side of the screw rod. The sleeve part includes a first sleeve rotatably connected with the screw rod, a second sleeve threadedly connected with the screw rod and a plurality of third sleeves sleeved on the outer side of the screw rod. The plurality of third sleeves are arranged between the first sleeve and the second sleeve. Partition rods are arranged on the first sleeve, the second sleeve and the third sleeves. Adjusting frames are movably arranged between the first sleeve and the third sleeve, between adjacent two third sleeves and between the third sleeve and the second sleeve. The adjusting frame includes two swing rods hinged to each other.

[0016] Preferably, the distance adjusting component further includes a rotating rod rotatably arranged on the forging heating furnace. A knob and a driving bevel gear are respectively arranged at the top and the bottom of the rotating rod. A driven bevel gear meshed with the driving bevel gear is arranged on the screw rod.

[0017] Preferably, the partition rod includes a first connecting rod rotatably arranged at the bottom side of the sleeve part through a first pin shaft. A torsion spring for the first connecting rod to reset and rotate is sleeved on the first pin shaft. One end of the first connecting rod far away from the sleeve part is connected with a partition part through a hinge.

[0018] Preferably, movable grooves are formed on both the unloading rack and the conveying rack. Two conveying shafts are symmetrically and rotatably connected in the movable grooves. Conveying wheels are arranged on each conveying shaft. A driving motor for driving the conveying shaft to rotate is arranged in the unloading rack.

[0019] Preferably, a U-shaped frame and a waste residue box are respectively arranged at the top and bottom of the blanking rack. An elastic telescopic rod is arranged on the U-shaped frame. One end of the elastic telescopic rod far away from the U-shaped frame is provided with an arc-shaped plate. A brush plate is arranged at the bottom of the arc-shaped plate. A guide plate is arranged at one end of the arc-shaped plate close to the forging heating furnace. The guide plate is inclined on the arc-shaped plate.

[0020] The invention also discloses a using method of the integrated forging heating equipment for forging production, including the following steps:

[0021] S1: According to the size and length of the forging heating bar stock, adjust the distance adjusting assembly. By rotating the knob, the knob drives the rotating rod and the driving bevel gear at the end of the rotating rod to rotate. The driving bevel gear meshes with the driven bevel gear on the screw rod, so that the screw rod rotates in the heating cavity. The second sleeve screwed with the screw rod moves horizontally along the axis of the screw rod, and then the distance between the second sleeve and the first sleeve changes. And a regulating frame is rotatably arranged between the first sleeve and the third sleeve, between adjacent two third sleeves, and between the third sleeve and the second sleeve. The two swing rods on the regulating frame automatically rotate when the second sleeve moves, so that the intervals between the first sleeve, the second sleeve and the third sleeve are equal, and the distance between the partition rods is adapted to the length of the bar stock forging.

[0022] S2: Place the bar stock to be forged and heated on the loading rack. When the bar stock arrives at the first door plate along the loading rack, control one of the hydraulic cylinders in the heat dissipation prevention mechanism to act. This hydraulic cylinder drives the first door plate and the third door plate to move upward through the connecting plate. At this time, the preheating cavity is opened, and the heating cavity is communicated with the blanking cavity. The bar stock forging on the loading rack passes through the feed port of the forging heating furnace and enters the preheating cavity to preheat the bar stock forging. The bar stock forging heated in the heating cavity moves down to the blanking cavity. Then control this hydraulic cylinder to drive the first door plate and the third door plate to reset through the connecting plate. At this time, the forging heating furnace is closed again, and the high-temperature air in the heating cavity does not overflow on a large scale and exchange too much with the outside air.

[0023] S3: Then control the other hydraulic cylinder of the heat dissipation prevention mechanism to act. This hydraulic cylinder drives the second door plate and the fourth door plate to move upward, so that the bar stock forging preheated in the preheating cavity enters the heating cavity, so that the bar stock forging reaches the die forging temperature, and the bar stock forging heated and completed in the blanking cavity moves to the blanking rack for subsequent processes.

[0024] S4: When the bar forging slides downward on the upper side of the conveying rack, the bar forging abuts against the partition rod, causing the partition rod to be stressed and rotate. When the bar forging passes over the partition rod, the partition rod rotates back to its original position under the action of the torsion spring. Moreover, a partition part is hinged to the bottom of the partition rod. When the partition rod rotates back to its original position, the partition part at the bottom automatically abuts against and bends the bar forging, facilitating the smooth reset of the partition rod. And the reset partition rod will abut against the previous bar forging under the pressing of the next bar forging, placing the partition rod between two bar forgings and separating them;

[0025] S5: Control the driving motor to operate, so that the output end of the driving motor drives the conveying shaft to rotate. Then, the conveying shaft drives the bar forging placed on the conveying rack and the blanking rack to rotate and move downward through the conveying wheel. Since the bar placed in the heating cavity is restricted by the partition rod, the bar will only rotate in the heating cavity, making the heating of each part of the bar uniform;

[0026] S6: The bar that moves from the forging heating furnace to the blanking rack exerts a force on the guide plate, causing the guide plate to drive the arc plate to move upward, so that the space formed between the arc plate and the blanking rack adapts to the diameter size of the bar forging. The bar rotates and is conveyed downward under the action of the conveying wheel. The arc plate is elastically arranged on the U-shaped frame, so that the brush plate at the bottom of the arc plate is in close contact with the outer side of the bar forging, enabling the brush plate to brush the scale on the outer side of the heated bar. The waste residue generated by cleaning falls into the waste residue box. After the scale on the outer side of the bar workpiece is removed, it enters the next production process along the blanking rack.

[0027] Compared with the prior art, the present invention provides an integrated forging heating device for forging parts and its use method, which has the following beneficial effects:

[0028] 1. For the integrated forging heating device for forging parts and its use method, by setting a heat dissipation prevention mechanism in the forging heating furnace, when the furnace door is opened, not too much external air of the furnace body will exchange with the hot air inside the furnace body, avoiding the rapid drop of the temperature inside the furnace body when the furnace door is opened, resulting in heat loss inside the furnace body. Moreover, the furnace body can preheat the incoming air, reducing the heat loss inside the furnace body when the furnace door is opened and the production cost of the forging heating furnace, shortening the heating time of the bar, and improving the production efficiency of the bar.

[0029] 2. For the integrated forging heating device for forging parts and its use method, by controlling the driving motor to operate, the output end of the driving motor drives the conveying shaft to rotate, and the conveying wheel on the conveying shaft drives the bar to rotate in the heating cavity, improving the heating effect of the bar inside the furnace body, making the heating of the bar uniform, and ensuring the subsequent forging effect of the bar.

[0030] 3. The integrated forging heating equipment for forging production and its usage method. By arranging a distance adjusting component in the heating cavity, the partition rods can separate billets of different lengths, preventing the billets from tightly abutting against each other, which may cause slow heating at the contact areas between the billets. Thus, the billets can be heated more evenly, ensuring the subsequent forging effect of the billets.

[0031] 4. The integrated forging heating equipment for forging production and its usage method. During the transportation of the billets by the conveyor wheels on the blanking rack, the billets rotate, enabling the brush plate to brush off the scale on the outer side of the heated billets, improving the surface finish of the workpieces. Therefore, it can prevent waste slag from entering the interior of the workpiece body during forging, thereby improving the processing and forging quality of the billets.

[0046] Embodiment 1:

[0047] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an integrated forging heating device for forging production includes a frame 1 with an inclined top, and further includes:

[0048] A forging heating furnace 2, which is fixedly arranged on the frame 1 and is used for heating forging materials. The front and rear ends of the forging heating furnace 2 are respectively provided with a feeding port and a discharging port, and a heat dissipation prevention mechanism is arranged between the feeding port and the discharging port;

[0049] A loading rack 3, which is arranged on the frame 1 and is located at the feeding port of the forging heating furnace 2 and is used for loading materials;

[0050] An unloading rack 4, which is arranged on the frame 1 and is located at the discharging port of the forging heating furnace 2 and is used for unloading materials; and

[0051] The conveying rack 5 is arranged inside the forging heating furnace 2, and the front and rear ends of the conveying rack 5 are respectively connected to the loading rack 3 and the unloading rack 4;

[0052] Among them, the loading rack 3, the unloading rack 4 and the conveying rack 5 are all arranged in a direction parallel to the top of the machine frame 1.

[0053] Specifically, the bar stock to be forged and heated is placed on the loading rack 3. The loading rack 3, the unloading rack 4 and the conveying rack 5 are all inclined, so that the bar stock placed on the loading rack 3 will move downward under its own weight. The bar stock passes through the loading rack 3, the conveying rack 5 and the unloading rack 4 in sequence. The bar stock is heated by the forging heating furnace 2 inside the conveying rack 5 to make the bar stock forging reach the die forging temperature. By arranging a heat dissipation prevention mechanism inside the forging heating furnace 2, when the furnace door is opened, there will be no excessive exchange of air outside the furnace body and hot air inside the furnace body, avoiding the rapid drop of the temperature inside the furnace body when the furnace door is opened, resulting in heat loss inside the furnace body, and the furnace body can preheat the incoming air, reducing the heat loss inside the furnace body when the furnace door is opened and the production operation cost of the forging heating furnace 2, shortening the bar stock heating time, and improving the production efficiency of the bar stock.

[0054] Embodiment 2:

[0055] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 For an integrated forging heating device for forging production, on the basis of Embodiment 1, furthermore, arc grooves 15 for the forging material to slide down are arranged on the loading rack 3, the unloading rack 4 and the conveying rack 5.

[0056] Specifically, by arranging the arc grooves 15 on the loading rack 3, the unloading rack 4 and the conveying rack 5, the bar stock to be forged and heated can slide down along the arc grooves 15, avoiding the random placement of the bar stock during the downward movement and affecting the subsequent processing of the bar stock forging.

[0057] Embodiment 3:

[0058] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 10, An integrated forging heating device for forging production. On the basis of Embodiment 1, further, the heat dissipation prevention mechanism includes a door panel part 6 slidably arranged on the forging heating furnace 2. A groove 605 matching with the conveying rack 5 is opened at the bottom of the door panel part 6. The door panel part 6 includes a first door panel 601, a second door panel 602, a third door panel 603 and a fourth door panel 604 arranged in sequence. Support plates 7 are arranged on both sides of the forging heating furnace 2. A hydraulic cylinder 701 is arranged on each support plate 7. The piston rods of the two hydraulic cylinders 701 are both connected with a connecting plate 702. One connecting plate 702 is connected with the first door panel 601 and the third door panel 603, and the other connecting plate 702 is connected with the second door panel 602 and the fourth door panel 604.

[0059] Furthermore, a preheating cavity is formed between the first door panel 601 and the second door panel 602, a heating cavity is formed between the second door panel 602 and the third door panel 603. A distance adjusting component is arranged in the heating cavity, and a blanking cavity is formed between the third door panel 603 and the fourth door panel 604.

[0060] Specifically, the bar stock to be forged and heated is placed on the loading rack 3. The bar stock slides down along the loading rack 3 under the action of its own gravity. The bar stock moves to the feed port of the forging heating furnace 2 and is blocked by the first door panel 601. Subsequently, control one of the hydraulic cylinders 701 in the heat dissipation prevention mechanism to act. This hydraulic cylinder 701 drives the first door panel 601 and the third door panel 603 to move upward through the connecting plate 702. At this time, the preheating cavity is opened, the heating cavity is communicated with the blanking cavity, and the bar stock forging on the loading rack 3 passes through the furnace body feed port and enters the preheating cavity. The bar stock forging that has been heated in the heating cavity moves down to the blanking cavity. Subsequently, control this hydraulic cylinder 701 to drive the first door panel 601 and the third door panel 603 to reset through the connecting plate 702. At this time, the forging heating furnace 2 is closed again, and the high-temperature air in the heating cavity does not overflow on a large scale. Then control the other hydraulic cylinder 701 of the heat dissipation prevention mechanism to act. This hydraulic cylinder 701 drives the second door panel 602 and the fourth door panel 604 to move upward, so that the preheated bar stock forging in the preheating cavity enters the heating cavity, and the bar stock forging that has been heated and placed in the blanking cavity moves to the blanking rack 4 for subsequent processes. The present invention can prevent excessive exchange of external air of the furnace body and the hot air inside the furnace body when the furnace door is opened, avoid the rapid drop of the temperature inside the furnace body when the furnace door is opened, reduce the heat loss inside the furnace body, and the furnace body can preheat the incoming air, reduce the heat loss inside the furnace body when the furnace door is opened and the production operation cost of the forging heating furnace 2, shorten the heating time of the bar stock, and improve the production efficiency of the bar stock forging.

[0061] Embodiment 4:

[0062] Refer to Figure 4 、 Figure 6 、 Figure 8 and Figure 9, an integrated forging heating device for forging production. Further, on the basis of Embodiment 3, the distance adjustment assembly includes a fixed plate 8 fixedly arranged in the heating cavity. A screw rod 801 is rotatably connected to the fixed plate 8. A sleeve part is arranged outside the screw rod 801. The sleeve part includes a first sleeve 802 rotatably connected to the screw rod 801, a second sleeve 803 threadedly connected to the screw rod 801, and a plurality of third sleeves 804 sleeved outside the screw rod 801. The plurality of third sleeves 804 are arranged between the first sleeve 802 and the second sleeve 803. Partition rods 806 are arranged on the first sleeve 802, the second sleeve 803, and the third sleeves 804. Adjusting frames 805 are movably arranged between the first sleeve 802 and the third sleeve 804, between adjacent two third sleeves 804, and between the third sleeve 804 and the second sleeve 803. The adjusting frame 805 includes two swing rods 8051 hinged to each other.

[0063] Further, the distance adjustment assembly further includes a rotating rod 9 rotatably arranged on the forging heating furnace 2. A knob 901 and a driving bevel gear 902 are respectively arranged at the top and bottom of the rotating rod 9. A driven bevel gear 807 meshed with the driving bevel gear 902 is arranged on the screw rod 801.

[0064] Further, the partition rod 806 includes a first connecting rod 8061 rotatably arranged at the bottom side of the sleeve part through a first pin shaft. A torsion spring 8062 for resetting the rotation of the first connecting rod 8061 is sleeved on the first pin shaft. One end of the first connecting rod 8061 far from the sleeve part is hinged to a partition part 8063.

[0065] Specifically, according to the size and length of the forging heated bar stock, the distance adjustment component is adjusted. By rotating the knob 901, the knob 901 drives the rotating rod 9 and the driving bevel gear 902 at the end of the rotating rod 9 to rotate. The driving bevel gear 902 meshes with the driven bevel gear 807 on the screw rod 801 to drive the screw rod 801 to rotate in the heating cavity. The second sleeve 803 screwed to the screw rod 801 moves horizontally along the axis 801 of the screw rod, so that the distance between the second sleeve 803 and the first sleeve 802 changes. And there are adjusting frames 805 rotatably arranged between the first sleeve 802 and the third sleeve 804, between adjacent two third sleeves 804, and between the third sleeve 804 and the second sleeve 803. When the second sleeve 803 moves, the two swing rods 8051 on the adjusting frame 805 automatically rotate, so that the intervals between the first sleeve 802, the second sleeve 803 and the third sleeve 804 are equal, and the distance between the partition rods 806 adapts to the length of the bar stock forging. When the bar stock forging slides down on the top of the conveying frame 5, the bar stock forging abuts against the partition rods 806, causing the partition rods 806 to be forced to turn over. When the bar stock forging passes over the partition rods 806, the partition rods 806 reset and rotate under the action of the torsion spring 8062. And the bottom of the partition rod 806 is hinged with a partition part 8063. When the partition rod 806 resets and rotates, the partition part 8063 at the bottom automatically abuts against and bends the bar stock forging, facilitating the smooth reset of the partition rod 806 and preventing the partition rod 806 from abutting against the bar stock when resetting, resulting in the failure of the partition rod 806 to reset. And the reset partition rod 806 will abut against the previous bar stock forging under the pressure of the next bar stock forging, so that the partition rod 806 is placed between two bar stocks and separates them, preventing the bar stocks from tightly abutting against each other, resulting in slow heating at the contact places between the bar stocks, so that the bar stocks are heated evenly in the heating cavity, ensuring the subsequent forging effect of the bar stocks; it should be noted that the distance adjustment component is made of high-temperature resistant alloy material to avoid being damaged by heating when placed in the heating cavity.

[0066] Embodiment 5:

[0067] Referring to Figure 4 、 Figure 5 and Figure 10 Based on Embodiment 4, further, movable grooves 10 are provided on both the blanking frame 4 and the conveying frame 5. Two conveying shafts 11 are symmetrically and rotatably connected in the movable grooves 10. A conveying wheel 111 is arranged on each conveying shaft 11. A driving motor 112 for driving the conveying shaft 11 to rotate is arranged in the blanking frame 4.

[0068] Specifically, by controlling the operation of the driving motor 112, the output end of the driving motor 112 drives the conveying shaft 11 to rotate, and then the conveying shaft 11 drives the bar forging placed on the conveying rack 5 and the blanking rack 4 to rotate and move downward through the conveying wheel 111. Since the bar placed in the heating chamber is restricted by the partition rod 806, the bar will only rotate in the heating chamber, improving the heating effect of the bar inside the furnace body, making the heating of each part of the bar uniform, and ensuring the subsequent forging effect of the bar.

[0069] Embodiment 6:

[0070] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 10 and Figure 11 Based on Embodiment 5, further, a U-shaped frame 12 and a waste residue box 13 are respectively arranged at the top and bottom of the blanking rack 4. An elastic telescopic rod 121 is arranged on the U-shaped frame 12. One end of the elastic telescopic rod 121 away from the U-shaped frame 12 is provided with an arc-shaped plate 122. A brush plate 123 is arranged at the bottom of the arc-shaped plate 122. A guide plate 14 is arranged at one end of the arc-shaped plate 122 close to the forging heating furnace 2. The guide plate 14 is inclined on the arc-shaped plate 122.

[0071] Specifically, the bar moved from the forging heating furnace 2 to the blanking rack 4 is placed between the arc-shaped plate 122 and the blanking rack 4. The bar rotates and is conveyed downward under the action of the conveying wheel 111. The arc-shaped plate 122 is elastically arranged on the U-shaped frame 12, so that the brush plate 123 at the bottom of the arc-shaped plate 122 is in close contact with the outer side of the bar forging, enabling the brush plate 123 to brush off the scale on the outer side of the heated bar. The waste residue generated by the cleaning falls into the waste residue box 13, which is convenient for improving the surface finish of the workpiece, thus avoiding the waste residue from entering the inside of the workpiece body during forging, and further improving the processing and forging quality of the bar; by providing a guide plate 14 at the front end of the arc-shaped plate 122, when the bar forging slides down along the blanking rack 4, it first contacts the guide plate 14, causing the guide plate 14 to be stressed and drive the arc-shaped plate 122 to move upward, and the elastic telescopic rod 121 is compressed. Then, the space formed between the arc-shaped plate 122 and the blanking rack 4 adapts to the diameter size of the bar forging, which is convenient for ensuring the cleaning effect of the bar forging and has strong practicability.

[0072] The present invention also discloses a usage method of an integrated forging and heating device for forging production, including the following steps:

[0073] S1: Adjust the distance adjustment component according to the size and length of the forging heated bar stock. By rotating the knob 901, the knob 901 drives the rotating rod 9 and the driving bevel gear 902 at the end of the rotating rod 9 to rotate. The driving bevel gear 902 meshes with the driven bevel gear 807 on the screw rod 801 to drive the screw rod 801 to rotate in the heating cavity. The second sleeve 803 screwed to the screw rod 801 moves horizontally along the axis of the screw rod 801, thereby changing the distance between the second sleeve 803 and the first sleeve 802. And between the first sleeve 802 and the third sleeve 804, between adjacent two third sleeves 804, and between the third sleeve 804 and the second sleeve 803, adjusting frames 805 are rotatably arranged. The two swing rods 8051 on the adjusting frame 805 automatically rotate when the second sleeve 803 moves, so that the intervals between the first sleeve 802, the second sleeve 803, and the third sleeve 804 are equal, and the distance between the partition rods 806 is adapted to the length of the bar stock forging;

[0074] S2: Place the bar stock to be forged and heated on the loading rack 3. When the bar stock arrives at the first door panel 601 along the loading rack 3, control one of the hydraulic cylinders 701 in the heat dissipation prevention mechanism to act. The hydraulic cylinder 701 drives the first door panel 601 and the third door panel 603 to move upward through the connecting plate 702. At this time, the preheating cavity is opened, the heating cavity is communicated with the blanking cavity, and the bar stock forging on the loading rack 3 passes through the feed port of the forging heating furnace 2 and enters the preheating cavity to preheat the bar stock forging. The bar stock forging that is heated and completed in the heating cavity moves down to the blanking cavity. Subsequently, control the hydraulic cylinder 701 to drive the first door panel 601 and the third door panel 603 to reset through the connecting plate 702. At this time, the forging heating furnace 2 is closed again, and the high-temperature air in the heating cavity does not overflow on a large scale and exchange too much with the outside air;

[0075] S3: Then control the other hydraulic cylinder 701 of the heat dissipation prevention mechanism to act. This hydraulic cylinder 701 drives the second door panel 602 and the fourth door panel 604 to move upward, so that the preheated bar stock forging in the preheating cavity enters the heating cavity, making the bar stock forging reach the die forging temperature, and the bar stock forging that is heated and completed in the blanking cavity moves to the blanking rack 4 for subsequent processes;

[0076] S4: When the bar stock forging slides down on the upper side of the conveying rack 5, the bar stock forging abuts against the partition rod 806, causing the partition rod 806 to be forced to turn over. When the bar stock forging passes over the partition rod 806, the partition rod 806 rotates back to its original position under the action of the torsion spring 8062. And the bottom of the partition rod 806 is hinged with a partition part 8063. When the partition rod 806 rotates back to its original position, the partition part 8063 at the bottom automatically abuts against and bends the bar stock forging, facilitating the smooth reset of the partition rod 806. And the reset partition rod 806 will abut against the previous bar stock forging under the pressing of the next bar stock forging, so that the partition rod 806 is placed between two bar stocks and separates them;

[0077] S5: Control the operation of the driving motor 112 so that the output end of the driving motor 112 drives the conveying shaft 11 to rotate. Further, the conveying shaft 11 drives the bar forging placed on the conveying frame 5 and the blanking frame 4 to rotate and move downward through the conveying wheel 111. Since the bar placed in the heating cavity is restricted by the partition rod 806, the bar will only rotate in the heating cavity, making the heating of each part of the bar uniform;

[0078] S6: The bar that moves from the forging heating furnace 2 to the blanking frame 4 exerts a force on the guide plate 14, causing the guide plate 14 to drive the arc plate 122 to move upward, so that the space formed between the arc plate 122 and the blanking frame 4 adapts to the diameter size of the bar forging. The bar rotates and is conveyed downward under the action of the conveying wheel 111. The arc plate 122 is elastically arranged on the U-shaped frame 12, so that the brush plate 123 at the bottom of the arc plate 122 is in close contact with the outer side of the bar forging, enabling the brush plate 123 to brush off the scale on the outer side of the heated bar. The waste residue generated by cleaning falls into the waste residue box 13. After the scale on the outer side of the bar workpiece is removed, it enters the next production process along the blanking frame 4.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
