Description

Technical Field

[0001] This utility model relates to the field of support roller forging technology, specifically to a closed-loop forging device for support rollers. Background Technology

[0002] Track rollers are used to support the weight of the tractor and roll on the track rails (track links) or track plates. They also restrain the tracks and prevent lateral slippage. They are generally forged in specific molds.

[0003] Currently, support rollers are forged at a single location during forging. When forging other locations is required, workers need to manually rotate the support roller to the forging position. The system cannot automatically rotate the support roller to each forging position, meaning it cannot automatically perform forging work on each location on the support roller. This reduces forging efficiency and increases workload. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a closed forging device for support rollers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A closed forging apparatus for support rollers, comprising:

[0007] A forging box, wherein a lower forging plate is fixedly connected to the bottom of the forging box, and a lower forging groove is provided at the upper end of the lower forging plate, and a support roller body is provided in the lower forging groove;

[0008] The rotating mechanism includes two vertical plates, each with a rotating shaft rotatably connected to its sidewall. Rectangular grooves are formed on the sidewalls of the two rotating shafts that are close to each other. A rectangular rod is slidably connected to the inner wall of each rectangular groove. The sidewall of the rectangular rod is elastically connected to the inner wall of the rectangular groove via multiple first springs. A motor is fixedly connected to the sidewall of each vertical plate, with the end of the motor's movable shaft away from the rectangular rod fixedly connected. The two vertical plates are located on either side of the lower forging plate.

[0009] Preferably, it also includes a forging mechanism, which includes two hydraulic cylinders fixedly connected to the upper end of the forging box. The movable ends of the two hydraulic cylinders are fixedly connected to an upper forging plate, and an upper forging groove is provided at the lower end of the upper forging plate.

[0010] Preferably, the forging box is provided with a moving mechanism for moving the two vertical plates. The moving mechanism includes two moving frames slidably connected to the bottom of the forging box. The side walls of the two vertical plates are slidably connected to the inner side walls of the two moving frames respectively. The lower end of the vertical plate is elastically connected to the bottom of the moving frame through multiple second springs.

[0011] Preferably, two electric push rods are fixedly connected to the side wall of the forging box near the moving frame, and the movable ends of the two electric push rods are fixedly connected to the side wall of the moving frame near them.

[0012] Preferably, two first wedge rods are fixedly connected to the bottom of the forging box, and second wedge rods are fixedly connected to the side walls of the two vertical plates that are close to each other, with the upper surface of the first wedge rods and the lower surface of the second wedge rods in contact.

[0013] Preferably, the forging box has a door hinged to its side wall, and the side wall of the door is fitted with tempered glass.

[0014] This utility model has the following beneficial effects:

[0015] 1. A rotating mechanism and a moving mechanism are set up. Two rectangular rods clamp the support roller body under the action of the first spring. Then, two motors are driven to rotate in the same direction, so that the two rotating shafts drive the two rectangular rods to rotate in the same direction, which in turn drives the support roller body to rotate. The forging position on the support roller body is automatically adjusted, which speeds up the forging efficiency of the support roller body. This avoids the problem that in the existing technology, the operator needs to manually rotate the support roller to the forging position. The existing technology cannot automatically perform forging and forming work on each position on the support roller, which reduces the forging efficiency and increases the workload.

[0016] 2. Set a first wedge rod and a second wedge rod. After the two rectangular rods can clamp the support roller body, the four electric push rods continue to extend. At this time, the two second wedge rods will move on the upper surface of the two first wedge rods, causing the two vertical plates to move up. Due to the presence of the first spring, the rectangular rods can slide into the rectangular groove without hindering the sliding of the vertical plates. The movement of the two vertical plates causes the two rectangular rods to drive the support roller body to move up and separate from the lower forging groove, which facilitates the rotation of the support roller body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A closed forging device for support rollers includes a forging box 1, a lower forging plate 3 fixedly connected to the bottom of the forging box 1, a lower forging groove 4 opened at the upper end of the lower forging plate 3, and a support roller body 2 disposed in the lower forging groove 4.

[0025] The forging mechanism includes two hydraulic cylinders 5 fixedly connected to the upper end of the forging box 1. The movable ends of the two hydraulic cylinders 5 are fixedly connected to an upper forging plate 6, and an upper forging groove 7 is opened at the lower end of the upper forging plate 6.

[0026] The support roller body 2 is located in the lower forging groove 4. When the two hydraulic cylinders 5 extend, the upper forging plate 6 moves down, and then the support roller body 2 is forged under the action of the upper forging groove 7.

[0027] The forging box 1 has a hinged door 19 on its side wall, and tempered glass 20 is installed on the side wall of the door 19.

[0028] When forging the support roller body 2, the box door 19 is closed to achieve a closed forging process for the support roller body 2, and the forging situation on the support roller body 2 can be observed through the tempered glass 20.

[0029] The rotating mechanism includes two vertical plates 10. The side walls of the two vertical plates 10 are rotatably connected to rotating shafts 12. The side walls of the two rotating shafts 12 that are close to each other are provided with rectangular grooves 13. The inner walls of the rectangular grooves 13 are slidably connected to rectangular rods 14. The side walls of the rectangular rods 14 are elastically connected to the inner side walls of the rectangular grooves 13 through multiple first springs 15. A motor 16 is fixedly connected to the side walls of the vertical plates 10. The end of the rotating shaft 12 at the movable end of the motor 16 that is away from the rectangular rod 14 is fixedly connected. The two vertical plates 10 are located on both sides of the lower forging plate 3.

[0030] The forging box 1 is provided with a moving mechanism for moving two vertical plates 10. The moving mechanism includes two moving frames 9 slidably connected to the bottom of the forging box 1. The side walls of the two vertical plates 10 are slidably connected to the inner side walls of the two moving frames 9 respectively. The lower end of the vertical plate 10 is elastically connected to the bottom of the moving frames 9 through multiple second springs 11.

[0031] Two electric push rods 8 are fixedly connected to the side wall of the forging box 1 near the moving frame 9, and the movable ends of the two electric push rods 8 are fixedly connected to the side wall of the moving frame 9 near them.

[0032] When forging is required at different positions on the support roller body 2, the four electric push rods 8 are extended, causing the two moving frames 9 to move closer together. In turn, the two moving frames 9 cause the two vertical plates 10 to move closer together, which in turn causes the two rotating shafts 12 and the two rectangular rods 14 to move closer together. This allows the two rectangular rods 14 to clamp the support roller body 2 under the action of the first spring 15. Subsequently, the two motors 16 are driven to rotate in the same direction, causing the two rotating shafts 12 to rotate in the same direction, which in turn causes the two rectangular rods 14 to rotate, thus rotating the support roller body 2. This automatically adjusts the forging position on the support roller body 2, speeding up the forging efficiency of the support roller body 2. This avoids the problem in the prior art where workers need to manually rotate the support roller to the forging position, which cannot automatically perform forging work at various positions on the support roller, thereby reducing forging efficiency and increasing workload.

[0033] Two first wedge rods 17 are fixedly connected to the bottom of the forging box 1, and two second wedge rods 18 are fixedly connected to the side walls of the two vertical plates 10 that are close to each other. The upper surface of the first wedge rod 17 is in contact with the lower surface of the second wedge rod 18.

[0034] It should be noted that the spring constant of the first spring 15 is very large. So when the two rectangular rods 14 first come into contact with the side wall of the support roller body 2, the two rectangular rods 14 can clamp the support roller body 2 under the elastic force of the first spring 15. Then the four electric push rods 8 continue to extend. At this time, the two second wedge rods 18 will move on the upper surface of the two first wedge rods 17, causing the two vertical plates 10 to move upward. And due to the presence of the first spring 15, the rectangular rods 14 can slide into the rectangular groove 13 without hindering the sliding of the vertical plates 10. The upward movement of the two vertical plates 10 causes the two rectangular rods 14 to drive the support roller body 2 to move upward and separate from the lower forging groove 4, which facilitates the rotation of the support roller body 2.

[0035] After the support roller body 2 rotates, the four electric push rods 8 are adjusted to retract, so that the two moving frames 9 drive the two vertical plates 10 away from each other. At this time, the two second wedge rods 18 separate from the two first wedge rods 17, and then the two vertical plates 10 move down to their original positions under the action of multiple second springs 11. The two rectangular rods 14 also separate from the side wall of the support roller body 2.

[0036] When forging the support roller body 2, the support roller body 2 is first placed in the lower forging groove 4, then the box door 19 is closed to achieve a closed forging process for the support roller body 2. Finally, the extension of the two hydraulic cylinders 5 is adjusted, at which time the upper forging plate 6 moves down, and then the support roller body 2 is forged under the action of the upper forging groove 7.

[0037] When it is necessary to forge different positions of the support roller body 2, the four electric push rods 8 are extended, which drives the two moving frames 9 to move closer to each other. Then, the two moving frames 9 drive the two vertical plates 10 to move closer to each other, and drive the two rotating shafts 12 and the two rectangular rods 14 to move closer to each other. Under the action of the first spring 15, the two rectangular rods 14 clamp the support roller body 2. Then, the four electric push rods 8 continue to extend. At this time, the two second wedge rods 18 will move on the upper surface of the two first wedge rods 17, causing the two vertical plates 10 to move upward. And due to the presence of the first spring 15, the rectangular rods 14 can slide into the rectangular groove 13 without hindering the sliding of the vertical plates 10. Then, the two vertical plates 10 move upward, causing the two rectangular rods 14 to drive the support roller body 2 to move upward and separate from the lower forging groove 4.

[0038] Then, the two motors 16 are driven to rotate in the same direction, which causes the two rotating shafts 12 to drive the two rectangular rods 14 to rotate in the same direction, which in turn drives the support roller body 2 to rotate, automatically adjusting the forging position on the support roller body 2 and speeding up the forging efficiency of the support roller body 2.

[0039] After the support roller body 2 rotates, the four electric push rods 8 are adjusted to retract, causing the two moving frames 9 to move the two vertical plates 10 away from each other. At this time, the two second wedge rods 18 separate from the two first wedge rods 17, and then the two vertical plates 10 move down to their original positions under the action of multiple second springs 11, so that the support roller body 2 enters the lower forging groove 4. Subsequently, the two rectangular rods 14 also separate from the side wall of the support roller body 2.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
