Description

Technical Field

[0001] This utility model relates to the field of plate rolling technology, and more specifically, to a rolling device for processing iron-based alloy plates. Background Technology

[0002] Iron-based alloy sheets are metal sheets made from iron-based alloys through rolling. Martensitic alloys are a type of iron-based alloy, with Cr as the main hardening element, along with strengthening elements such as Si, Mo, Mn, V, and W. The total alloy element content does not exceed 10%. The coating structure adopts low-carbon martensite, exhibiting good machinability, excellent impact toughness, and good resistance to stress fatigue and thermal fatigue. The material is used for submerged arc welding of metal wires and tubular wires, resulting in good weldability and resistance to cracking. Iron-based alloy sheets are generally used for parts where there is no lubrication between metals during rolling or sliding, such as hot-rolled work rolls, support rolls, continuous casting machine rolls, guide rolls, straightening rolls, and excavator rolls.

[0003] Existing rolling mills mostly require additional hydraulic devices to apply pressure to the rolling rolls in order to complete the rolling process. Moreover, they can only drive the different rolling rolls to rotate by moving the sheet metal. Because the sheet metal moving speed is not high, this rolling method requires a long time to complete the rolling process.

[0004] Therefore, a drive device is needed to rotate the rolling rolls, thereby increasing the speed of the sheet metal movement and improving the efficiency of the rolling process. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rolling device for processing iron-based alloy plates that utilizes a cylinder support to pressurize the rolling rolls, eliminating the need for a separate hydraulic component, and uses a drive to rotate multiple sets of rolling rolls, thereby accelerating the movement speed of the plate and improving the rolling efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rolling apparatus for processing iron-based alloy plates includes a horizontally arranged rolling support, an upper rolling roll assembly arranged along the length direction of the rolling support, and a lower rolling roll assembly arranged at the bottom of the upper rolling roll assembly. The rolling support includes a horizontal support with a rectangular structure and a vertical support arranged vertically at the end of the horizontal support. The upper rolling roll assembly includes two sets of upper rolling mounting frames symmetrically arranged along the width direction of the rolling support and an upper rolling roll installed between the two sets of upper rolling mounting frames. The lower rolling roll assembly includes two sets of lower rolling mounting frames arranged at the bottom of the two sets of upper rolling mounting frames and a first lower rolling roll and a second lower rolling roll symmetrically arranged about the length direction of the upper rolling mounting frames.

[0008] The present invention is further configured such that: the upper rolling mounting frame is arranged vertically, and a set of rolling drive cylinders is arranged at the top center position; the bottom of the rolling drive cylinders is connected downward to a roller mounting ring; a sliding groove is provided through the upper rolling mounting frame at the position corresponding to the roller mounting ring, and the roller mounting ring is slidably installed inside the sliding groove; a circular through hole adapted to the outer diameter of the upper rolling roll is provided through the roller mounting ring, and it is sleeved on the outer wall of the upper rolling mounting frame.

[0009] The present invention is further configured such that: a set of rolling auxiliary cylinders are rotatably connected to the side wall of the upper rolling mounting frame away from the center of the upper rolling roll, and the bottom of the rolling auxiliary cylinders is rotatably connected to the bottom of the horizontal support; two sets of roller shaft mounting rings are respectively installed through both ends of the upper rolling roll, and the end of the roller roll near the vertical support extends to the bottom of the vertical support.

[0010] By adopting the above technical solution, the extension and retraction of the rolling drive cylinder can drive the roller mounting ring to move vertically within the upper rolling mounting frame, and simultaneously drive the upper rolling roll to move vertically, thereby adjusting the distance between the upper rolling roll and the first lower rolling roll and the second lower rolling roll.

[0011] The present invention is further configured such that: the lower rolling mounting frame is a rectangular structure with a width adapted to the upper rolling mounting frame, and its bottom is connected to the top of the horizontal support; the lower rolling mounting frame and the upper rolling mounting frame are rotatably connected; the lower rolling mounting frame is arranged vertically to the top of the horizontal support; a first lower rolling roll and a second lower rolling roll are rotatably connected between the two sets of lower rolling mounting frames; the two ends of the first lower rolling roll and the second lower rolling roll are respectively arranged through the two sets of lower rolling mounting frames; wherein, a set of first meshing gears is provided at the end of the first lower rolling roll near the vertical support, and a set of second meshing gears is provided at the end of the second lower rolling roll near the vertical support.

[0012] The present invention is further configured such that: the first meshing gear and the second meshing gear mesh with each other, and a set of main mating gears are provided at the bottom of the two gears; the main mating gears are rotatably mounted on the side wall of the lower rolling mounting frame near the vertical support, and a drive motor is abutted on the side away from the lower rolling mounting frame.

[0013] The present invention is further configured such that: the drive motor is arranged along the length direction of the horizontal support, and its output end is provided with a gear that meshes with the main cooperating gear; the gear at the output end of the drive motor meshes with the main cooperating gear and the first meshing gear respectively.

[0014] By adopting the above technical solution, the drive motor can drive the gear set on its output end to rotate. During this process, the meshing of the main meshing gear can synchronously drive the first meshing gear and the second meshing gear to rotate. Finally, under the action of the first meshing gear and the second meshing gear, the first lower rolling roll and the second lower rolling roll will rotate.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. The extension and retraction of the rolling drive cylinder can drive the upper rolling roll to move vertically. During the rolling process, the rolling drive cylinder directly applies pressure to the upper rolling roll, causing the upper rolling roll to move towards the first lower rolling roll and the second lower rolling roll, thereby completing the rolling of the iron-based alloy plate.

[0017] 2. A gear is provided at the end of the drive motor. The drive motor can drive the first and second lower rolling rolls to rotate through the meshing of the main meshing gear, the first meshing gear and the second meshing gear, thereby accelerating the movement speed of the iron-based alloy plate and improving the rolling efficiency of the iron-based alloy plate.

[0030] See Figure 1-3 The rolling support 1 includes a horizontal support 11 with a rectangular structure and a vertical support 12 vertically disposed at the end of the horizontal support 11.

On the one hand, it can adjust the distance between the upper rolling roll 22 and the first lower rolling roll 32 and the second lower rolling roll 33; on the other hand, it can directly apply pressure to the upper rolling roll 22 during the rolling process using the rolling drive cylinder 23, causing the upper rolling roll 22 to move towards the first lower rolling roll 32 and the second lower rolling roll 33, thereby completing the rolling of the iron-based alloy plate.

[0032] See Figure 1-4 A set of rolling auxiliary cylinders 25 is rotatably connected to the side wall of the upper rolling mounting frame 21 away from the center of the upper rolling roll 22. The bottom of the rolling auxiliary cylinders 25 is rotatably connected to the bottom of the horizontal support 11.

The first lower rolling roll 32 and the second lower rolling roll 33 are symmetrically arranged about the length of the upper rolling mounting frame 21. The first lower rolling roll 32 and the second lower rolling roll 33 are respectively installed with two sets of lower rolling mounting frames 31 passing through both ends. During the rotation of the first lower rolling roll 32 and the second lower rolling roll 33, the iron-based alloy plate placed on top of the first lower rolling roll 32 and the second lower rolling roll 33 can be moved synchronously.

A set of main mating gears 35 is provided at the bottom of the first meshing gears 36 and the second meshing gears 37. The main mating gears 35 are rotatably mounted on the side wall of the lower rolling mounting frame 31 near the vertical support 12, and a drive motor 34 is abutted on the side away from the lower rolling mounting frame 31. The drive motor 34 is arranged along the length of the horizontal support 11, and its output end is provided with gears that mesh with the main mating gears 35. The gears at the output end of the drive motor 34 mesh with the main mating gears 35 and the first meshing gears 36 respectively. The drive motor 34 can drive the gear set on its output end to rotate. During this process, the meshing of the main meshing gear 35 can synchronously drive the first meshing gear 36 and the second meshing gear 37 to rotate. Finally, under the action of the first meshing gear 36 and the second meshing gear 37, the first lower rolling roll 32 and the second lower rolling roll 33 are driven to rotate, thereby accelerating the moving speed of the iron-based alloy plate and improving the rolling efficiency of the iron-based alloy plate.
