Description

TECHNICAL FIELD

[0001] The utility model relates to hot forging surface treatment technical field, concretely is a kind of hot forging surface treatment device. BACKGROUND

[0002] Hot forging is heated to high temperature, then through die forging forming, due to the commonality of hot forging, after heating, the surface of blank will produce more oxide skin, before blank enters die forging officially, oxide skin on its surface needs to be removed, to ensure the surface quality of later forging.

[0003] The existing hot forging surface treatment method, commonly adopt double-roller type oxide skin removing machine to remove the oxide skin produced on the surface of hot forging, double-roller type oxide skin removing machine is mainly composed of rack, double-roller assembly and driving mechanism, when cleaning the oxide skin produced on the surface of hot forging, first, place bar-shaped metal blank between two rollers, then drive two rollers to rotate by driving mechanism, rotating roller surface contacts with the surface of metal blank, and applies pressure and friction force to it, under the extrusion and shearing action, oxide skin is broken and falls off from the surface of blank, so that the oxide skin on the surface of hot forging can be removed.

[0004] When using double-roller type oxide skin removing machine to remove the oxide skin produced on the surface of hot forging, a large amount of broken oxide skin chips are produced during the removal of oxide skin, since the existing hot forging surface treatment device lacks protection mechanism, oxide skin chips splash everywhere, operator is easy to be injured by splashing, cause serious work injury accident, and since lacking effective material receiving mechanism, oxide skin chips scatter everywhere, which not only increases the burden of cleaning work, but also may pollute working environment, therefore, aiming at the above problems, a kind of hot forging surface treatment device is proposed. UTILITY MODEL CONTENTS

[0005] In order to make up for the deficiencies of prior art, solve the problems raised in the background art, the utility model provides a kind of hot forging surface treatment device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A surface treatment device for hot forgings according to this utility model includes a frame, a protective cover fixedly connected to the top side of the frame, a discharge port on one side of the protective cover, and a feed port on the top of the protective cover. Two limiting slide rails are fixedly connected to both sides of the feed port, and a sealing plate is slidably mounted on the two limiting slide rails. Support seats are fixedly connected to both sides of the protective cover, and a first pneumatic cylinder is mounted on each of the two support seats. A first pneumatic rod is mounted on the actuating end of each of the two first pneumatic cylinders, and a connecting block is fixedly connected to the other end of each of the two first pneumatic rods, with the connecting block fixedly connected to the sealing plate. During the process of removing oxide scale from the surface of hot forgings, a large amount of broken oxide scale debris is generated. By setting up a protective cover, the splashing of oxide scale debris can be prevented. In order to prevent oxide scale debris from splashing out through the feed inlet, sealing plates are set on both sides of the feed inlet. When the metal billet is placed between the two rollers, the first pneumatic cylinder is activated to bring the two sealing plates closer together, thereby sealing the feed inlet and preventing oxide scale debris from splashing out of the feed inlet. The fully enclosed protective cover can intercept oxide scale debris or metal fragments thrown out at high speed, effectively preventing oxide scale debris from splashing and avoiding scratches, burns or eye injuries to operators.

[0007] Preferably, a waste slag collection box is fixedly connected to the bottom side of the frame. A slag discharge port is opened on one side of the waste slag collection box. A threaded rod is rotatably installed inside the waste slag collection box. A movable sleeve is fitted onto the threaded rod, and a semi-circular push plate is fixedly connected to the movable sleeve. The arc-shaped surface of the semi-circular push plate is in contact with the bottom inner wall of the waste slag collection box. A first motor is installed at one end of the waste slag collection box away from the slag discharge port. The output end of the first motor is connected to one end of the threaded rod. When removing oxide scale from the surface of hot forgings, the waste slag collection box intercepts the oxide scale after it is removed. The oxide scale fragments fall into the waste collection box, effectively collecting them and preventing them from scattering everywhere. This ensures the cleanliness of the ground and the surrounding environment, reducing pollution to the working environment. When the collected oxide scale fragments in the waste collection box reach a certain amount, the first motor is started, causing the threaded rod to rotate. This, in turn, causes the movable sleeve to move the semi-circular push plate along the waste collection box, allowing the collected oxide scale fragments at the bottom of the waste collection box to be discharged through the slag discharge port, facilitating the removal of the collected oxide scale fragments from the waste collection box.

[0008] Preferably, two rotating shafts are rotatably mounted inside the frame, each shaft is fitted with a roller, and a driven gear is fitted at one end of each shaft. A fixed frame is fixed to one side of the frame, and a second motor is mounted on the fixed frame. A drive gear is mounted on the output end of the second motor, and the drive gear meshes with the two driven gears. When removing oxide scale from the surface of the hot forging, the second motor is started, causing the drive gear to rotate, which in turn forces the two driven gears to rotate. The two driven gears drive the two rollers to rotate, and the rotating roller surfaces come into contact with the surface of the metal blank, applying pressure and friction to it, thereby removing the oxide scale from the surface of the hot forging to ensure the processing quality of the subsequent forging surface.

[0009] Preferably, two limiting rods are fixedly connected inside the protective cover, and each limiting rod is fitted with a limiting sleeve. A connecting rod is fixedly connected between the two limiting sleeves, and a pusher plate is fixedly connected to the connecting rod. A second pneumatic cylinder is installed on the side of the protective cover away from the discharge port. A second pneumatic rod is fitted to the working end of the second pneumatic cylinder, and the other end of the second pneumatic rod is fixedly connected to the connecting rod. A third pneumatic cylinder is installed on the top side of the protective cover, and a third pneumatic rod is fitted to the working end of the third pneumatic cylinder. A mounting plate is fixedly connected to the bottom end of the third pneumatic rod, and a baffle plate is fixedly connected to the bottom side of the mounting plate. When removing the oxide scale from the surface of the hot forging, the third pneumatic cylinder is activated to move the baffle plate downwards. At the same time, the second pneumatic cylinder is activated. With the cooperation of the limit rod and the limit sleeve, the connecting rod and the pusher plate move stably. Through the cooperation of the baffle plate and the pusher plate, the two ends of the metal billet can be effectively limited and clamped. As the two rollers drive the metal billet to rotate, the oxide scale at both ends can also be removed. Thus, the oxide scale on the periphery and both ends of the hot forging can be removed simultaneously, thereby comprehensively removing the oxide scale from the surface of the hot forging and further ensuring the surface processing quality of subsequent products.

[0010] The advantages of this utility model are:

[0011] 1. This utility model generates a large amount of broken oxide scale debris during the process of removing oxide scale from the surface of hot forgings. By setting up a protective cover, the splashing of oxide scale debris can be prevented. In order to prevent oxide scale debris from splashing out through the feed inlet, sealing plates are set on both sides of the feed inlet. When the metal billet is placed between the two rollers, the first pneumatic cylinder is activated to bring the two sealing plates closer together, thereby sealing the feed inlet and preventing oxide scale debris from splashing out from the feed inlet. The fully enclosed protective cover can intercept oxide scale debris or metal fragments thrown out at high speed, effectively preventing the splashing of oxide scale debris and avoiding scratches, burns or eye injuries to operators.

[0012] 2. When removing oxide scale from the surface of hot forgings, this utility model uses a waste collection box. Oxide scale fragments intercepted by the protective cover fall into the waste collection box, thus effectively collecting the oxide scale fragments and preventing them from scattering everywhere. This ensures the cleanliness of the ground and the environment around the equipment, while reducing pollution to the working environment. Attached Figure Description

[0023] Please see Figures 1-5 As shown, a surface treatment device for hot forgings includes a frame 1, a protective cover 2 fixedly connected to the top side of the frame 1, a discharge port 3 on one side of the protective cover 2, and a feed port 4 on the top of the protective cover 2. Two limiting slide rails 5 are fixedly connected to both sides of the feed port 4, and a sealing plate 6 is slidably mounted on each of the two limiting slide rails 5. Support seats 7 are fixedly connected to both sides of the protective cover 2, and a first pneumatic cylinder 8 is mounted on each of the two support seats 7. A first pneumatic rod is mounted on the actuating end of each of the two first pneumatic cylinders 8, and a connecting block 9 is fixedly connected to the other end of each of the two first pneumatic rods, with the connecting block 9 fixedly connected to the sealing plate 6. During operation, the device removes oxide scale from the surface of the hot forgings. During the process, a large amount of broken oxide scale debris is generated. By setting up a protective cover 2, the splashing of oxide scale debris can be prevented. In order to prevent oxide scale debris from splashing out through the feed inlet 4, sealing plates 6 are set on both sides of the feed inlet 4. When the metal billet is placed between the two rollers 16, the first pneumatic cylinder 8 is activated to bring the two sealing plates 6 closer to each other, thereby sealing the feed inlet 4 and preventing oxide scale debris from splashing out from the feed inlet 4. The fully enclosed protective cover 2 can intercept oxide scale debris or metal fragments thrown out at high speed, effectively preventing the splashing of oxide scale debris and avoiding scratches, burns or eye injuries to operators.

[0024] A waste slag collection box 10 is fixedly connected to the bottom side of the frame 1. A slag discharge port 11 is opened on one side of the waste slag collection box 10.

A first motor 12 is installed at one end of the waste slag collection box 10 away from the slag discharge port 11. The output end of the first motor 12 is connected to one end of the threaded rod 13. During operation, when removing oxide scale from the surface of hot forgings, the oxide scale intercepted by the protective cover 2 is removed by setting up the waste slag collection box 10. The oxide scale fragments will fall into the waste collection box 10, thereby effectively collecting the oxide scale fragments and preventing them from scattering everywhere. This ensures the cleanliness of the ground and the environment around the equipment, while reducing pollution to the working environment. When the oxide scale fragments collected in the waste collection box 10 reach a certain amount, the first motor 12 is started, causing the threaded rod 13 to rotate. This causes the movable sleeve 14 to drive the semi-circular push plate 15 to move along the waste collection box 10, thereby discharging the oxide scale fragments collected at the bottom of the waste collection box 10 through the slag discharge port 11, making it easy to remove the collected oxide scale fragments from the waste collection box 10.

[0025] Please see Figures 2-3 and Figures 6-7 As shown, two rotating shafts are rotatably installed inside the frame 1. Rollers 16 are mounted on both rotating shafts, and driven gears 17 are mounted on one end of each rotating shaft. A fixed frame 18 is fixed to one side of the frame 1, and a second motor 19 is mounted on the fixed frame 18. A drive gear 20 is mounted on the output end of the second motor 19, and the drive gear 20 meshes with the two driven gears 17. During operation, when removing the oxide scale from the surface of the hot forging, the metal billet to be processed is first placed between the two rollers 16 through the feed port 4. Then, the first pneumatic cylinder 8 is started to block the feed port 4 with two sealing plates 6. Then, the second motor 19 is started to make the drive gear 20 rotate, which in turn forces the two driven gears 17 to rotate. The two driven gears 17 drive the two rollers 16 to rotate. The rotating roller surfaces come into contact with the surface of the metal billet and apply pressure and friction to it, thereby removing the oxide scale from the surface of the hot forging to ensure the processing quality of the subsequent forging surface.

[0026] Two limiting rods 25 are fixedly connected inside the protective cover 2. Each limiting rod 25 is fitted with a limiting sleeve 26. A connecting rod 27 is fixedly connected between the two limiting sleeves 26. A pusher plate 28 is fixedly connected to the connecting rod 27. A second pneumatic cylinder 29 is installed on the side of the protective cover 2 away from the discharge port 3. A second pneumatic rod is fitted to the working end of the second pneumatic cylinder 29, and the other end of the second pneumatic rod is fixedly connected to the connecting rod 27. A third pneumatic cylinder 21 is installed on the top side of the protective cover 2. A third pneumatic rod 22 is fitted to the working end of the third pneumatic cylinder 21. A mounting plate 23 is fixedly connected to the bottom end of the third pneumatic rod 22, and a baffle plate 24 is fixedly connected to the bottom side of the mounting plate 23. During operation, when removing oxide scale from the surface of the hot forging, the metal... After the metal blank is placed between the two rollers 16, the third pneumatic cylinder 21 is activated, causing the third pneumatic rod 22 to move the baffle plate 24 downward. At the same time, the second pneumatic cylinder 29 is activated. With the cooperation of the limiting rod 25 and the limiting sleeve 26, the second pneumatic rod drives the connecting rod 27 and the pusher plate 28 to move stably. Through the cooperation of the baffle plate 24 and the pusher plate 28, the two ends of the metal blank can be effectively limited and clamped. During the rotation of the metal blank by the two rollers 16, the oxide scale at both ends can also be removed. Thus, the oxide scale on the periphery and both ends of the hot forging can be removed at the same time, thereby comprehensively removing the oxide scale on the surface of the hot forging and further ensuring the surface processing quality of subsequent products.

[0027] Working Principle: When using a double-roller descaling machine to remove oxide scale from the surface of hot forgings, a large amount of broken oxide scale debris is generated during the removal process. Due to the lack of protective mechanisms in existing hot forging surface treatment devices, oxide scale debris flies everywhere, easily injuring operators and causing serious work-related accidents. Furthermore, the lack of an effective receiving mechanism causes oxide scale debris to scatter, increasing the cleaning workload and potentially polluting the working environment. Therefore, to address these problems, a surface treatment device for hot forgings is proposed. When removing oxide scale from the surface of hot forgings, a protective cover 2 is installed to prevent the flying of oxide scale debris. To prevent oxide scale debris from flying out through the feed inlet 4, sealing plates 6 are installed on both sides of the feed inlet 4. When the metal billet is placed between the two rollers 16, the first pneumatic cylinder 8 is activated, causing the two sealing plates 6 to move closer together, thereby sealing the feed inlet 4 and allowing the metal billet to pass through. To prevent oxide scale debris from splashing out of the feed inlet 4, the fully enclosed protective cover 2 can intercept oxide scale debris or metal fragments thrown out at high speed, effectively preventing oxide scale debris from splashing and avoiding scratches, burns or eye injuries to operators; by setting up a waste slag collection box 10, the oxide scale debris intercepted by the protective cover 2 will fall into the waste slag collection box 10, thereby effectively collecting the oxide scale debris and preventing the oxide scale debris from scattering everywhere, ensuring the cleanliness of the ground and the environment around the equipment, and reducing pollution to the working environment. When the oxide scale debris collected in the waste slag collection box 10 reaches a certain amount, the first motor 12 is started, causing the threaded rod 13 to rotate, which in turn causes the movable sleeve 14 to drive the semi-circular push plate 15 to move along the waste slag collection box 10, thereby discharging the oxide scale debris collected at the bottom of the waste slag collection box 10 through the slag discharge port 11, making it easy to remove the collected oxide scale debris from the waste slag collection box 10;

[0028] When removing oxide scale from the surface of hot forgings, the metal billet to be treated is first placed between two rollers 16 through the feed inlet 4. Then, the first pneumatic cylinder 8 is activated, causing the two sealing plates 6 to block the feed inlet 4. Next, the third pneumatic cylinder 21 is activated, causing the third pneumatic rod 22 to move the baffle plate 24 downwards. Simultaneously, the second pneumatic cylinder 29 is activated. With the cooperation of the limiting rod 25 and the limiting sleeve 26, the second pneumatic rod drives the connecting rod 27 and the pusher plate 28 to move stably. Through the cooperation of the baffle plate 24 and the pusher plate 28, the metal billet can be removed. The blank is effectively clamped at both ends, and then the second motor 19 is started to make the drive gear 20 rotate, which in turn forces the two driven gears 17 to rotate. The two driven gears 17 drive the two rollers 16 to rotate. The rotating roller surfaces come into contact with the surface of the metal blank and apply pressure and friction to it. With the cooperation of the baffle plate 24 and the push plate 28, the oxide scale on the periphery and both ends of the hot forging can be removed at the same time, thus comprehensively removing the oxide scale on the surface of the hot forging and further ensuring the surface processing quality of subsequent products.
