[0002] The vertical ring rolling machine is a core roller driven by an electric motor to rotate. During the downward pressure of the main rolling roller, a pair of rollers is formed with the core roller. The ring blank on the core roller is rolled repeatedly in a cycle. The inner and outer diameters of the ring are expanded and the wall thickness is reduced to gradually form. When the ring rolling machine on the market is working, a layer of oxide scale will form on the blank. These oxide scales adhere firmly and are difficult to fall off naturally. The oxide scales are hard and brittle. If they are not cleaned, they may be pressed into the inside of the ring during the ring rolling process, resulting in pits, cracks or other defects on the surface of the ring, which seriously affects the geometric dimensional accuracy and surface quality of the ring, and may even cause the ring to be scrapped. At the same time, when the ring rolling machine is processing the workpiece, the oxide scale on the surface of the workpiece falls directly to the ground, which makes the workplace very dirty and needs to be cleaned and collected manually, which brings great inconvenience and adds to the work content.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0022] The embodiment of the present application provides a scraping mechanism for a vertical CNC ring rolling machine. The scraping mechanism of the vertical CNC ring rolling machine can clean the oxide scale on the surface of the workpiece through the scraping assembly, thereby preventing the oxide scale from being pressed into the interior of the ring during the ring rolling process, resulting in pits, cracks or other defects on the surface of the ring, seriously affecting the geometric dimensional accuracy and surface quality of the ring, and may even cause the ring to be scrapped.

[0023] The scraping mechanism of the vertical CNC ring rolling machine is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example 1

[0025] See also Figure 1-Figure 7 In the embodiment, a scraping mechanism of a vertical CNC ring rolling machine is provided, comprising: a base plate 1, a mounting plate 11 is fixedly mounted on the top of the base plate 1, a core roller 12 is fixedly connected to the middle position of one side of the mounting plate 11, auxiliary rolling rollers 13 are respectively arranged on both sides below the core roller 12, a main rolling roller 14 is arranged directly above the core roller 12, a mounting platform 15 is located at a position on one side of the mounting plate 11 close to one side of the main rolling roller 14, a scraping assembly is arranged on one side of the mounting platform 15, and is used to scrape off the oxide scale on the surface of the workpiece, and a collecting assembly is arranged on one side of the mounting plate 11, and is used to centrally collect the cleaned oxide scale. Example 2

[0026] On the basis of Example 1, the scraper assembly includes: a gear plate 2 rotatably connected to one side of the mounting platform 15, a pneumatic rod 21 is fixedly installed on one side of the gear plate 2, and a mounting frame 22 is fixedly connected to the bottom end of the pneumatic rod 21, and slide grooves 23 are respectively opened on the inner walls on the opposite sides of the mounting frame 22, and steel brushes 24 are slidably connected inside the two slide grooves 23, and threaded holes 25 are respectively opened on the opposite sides of the two slide grooves 23 near the bottom, and the two threaded holes 25 are threadedly connected to limit bolts 26, and one end of the limit bolt 26 extends into the slide groove 23, and the two slide grooves 23 are slidably connected to the inside of the pressing plate 27, and the top of the pressing plate 27 is connected to the mounting frame 2 2 is connected with a spring 28, and limiting grooves 29 are respectively provided on opposite sides of the inner walls of the two slide grooves 23, and limiting blocks 210 used in conjunction with the limiting grooves 29 are respectively provided on both sides of the pressure plate 27. A device box 211 is fixedly installed at a position close to the gear plate 2 on one side of the mounting platform 15, and a driving gear 212 is rotatably connected inside the device box 211. One side of the gear plate 2 extends into the device box 211 and is engaged with the driving gear 212. A driving rod 213 is threadedly connected inside the driving gear 212. A servo motor 214 is fixedly installed on one side of the device box 211, and the rotating shaft of the servo motor 214 is connected to the driving rod 213.

[0027] When it is necessary to clean the oxide scale on the surface of the workpiece, the servo motor 214 is started to drive the driving rod 213 to rotate. The driving rod 213 rotates and screws with the driving gear 212, thereby driving the driving gear 212 to rotate. The driving gear 212 rotates and screws with the gear plate 2, thereby driving the gear plate 2 to rotate. The rotation direction of the gear plate 2 is adjusted by controlling the rotation direction of the servo motor 214. When the gear plate 2 rotates, it drives the pneumatic rod 21 installed on one side to rotate, thereby adjusting the inclination direction of the pneumatic rod 21 to a suitable angle, and then the pneumatic rod 21 is started. After the pneumatic rod 21 is started, it pushes the installation frame 22 out, and the installation frame 22 drives the steel brush 24 to fit with the surface of the workpiece. When the workpiece rotates, it rubs against the steel brush 24, thereby cleaning the oxide scale on the surface of the workpiece. When the steel brush 24 contacts the surface of the workpiece, it is affected by the reaction force and moves in the opposite direction along the inside of the two slide grooves 23, and the steel brush 24 pushes the pressure plate The limit blocks 210 on both sides are moved in the limit grooves 29 when the pressing plate 27 moves. The limit grooves 29 can limit the moving range of the pressing plate 27 without affecting the movement of the steel brush 24. The pressing plate 27 moves upward to squeeze the spring 28. The spring 28 is squeezed and contracts to store energy. The elasticity of the spring 28 can play a buffering role, and the elasticity of the spring 28 can make the steel brush 24 always fit the surface of the workpiece. When replacing the steel brush 24, the limit bolt 26 is screwed out so that the limit bolt 26 withdraws from the inside of the slide groove 23, thereby releasing the limitation on the movable range of the bottom of the slide groove 23. At this time, the steel brush 24 is taken out from the inside of the slide groove 23, and a new steel brush 24 is replaced. The steel brush 24 is pressed to move it upward to the position of the threaded hole 25, and the limit bolt 26 is screwed in so that one end of it passes through the threaded hole 25, thereby limiting the downward movement range of the steel brush 24 and preventing the steel brush 24 from sliding out of the slide groove 23. Example 3

[0028] On the basis of Example 1, the collecting component includes: a material receiving basin 3 fixedly connected to the bottom position of one side of the mounting plate 11, the material receiving basin 3 is arranged in an inverted trapezoidal structure, a material discharge pipe 31 is fixedly connected to the bottom of the material receiving basin 3, a collecting frame 32 is arranged below the material discharge pipe 31, two pairs of rollers 33 are arranged at the bottom of the collecting frame 32, two crushing rollers 34 are arranged between the inner walls of the material receiving basin 3 near the position of the material discharge pipe 31, an outer cover 35 is provided on one side of the material receiving basin 3, and a driving motor 36 is fixedly installed on one side of the outer cover 35, one end of the rotating shaft of the two crushing rollers 34 extends to the inside of the outer cover 35 and is respectively fixedly connected to the driven gears 37, the two driven gears 37 are meshed and connected, and the rotating shaft at one end of the driving motor 36 is connected to one of the driven gears 37.

[0029] The cleaned oxide scale falls naturally and falls into the receiving basin 3. The oxide scale gathers at the bottom position along the inclined surface of the receiving basin 3. At this time, the driving motor 36 is started to drive one of the driven gears 37 to rotate. The driven gear 37 drives the crushing roller 34 connected at one end to rotate counterclockwise. When the driven gear 37 rotates, it meshes with the other driven gear 37 and rotates clockwise, thereby driving the other crushing roller 34 to rotate clockwise. In this way, the two crushing rollers 34 continuously roll the oxide scale between the two for crushing. The crushed oxide scale falls into the collection frame 32 through the discharge pipe 31. The roller 33 can facilitate the movement of the collection frame 32, which is convenient for transportation and replacement of empty collection frames 32.
