Description

Technical Field

[0001] The utility model relates to the technical field of aluminum sheet and strip production, and particularly relates to a device for bending and warping the head of an aluminum sheet and strip material. Background Art

[0002] A rolling mill is a device for realizing the metal rolling process, generally referring to the equipment for completing the whole process of rolled material production. At present, in the production and processing of aluminum coils, a rolling mill is usually used to roll aluminum sheets into aluminum sheet and strip. After the aluminum sheet and strip rolling is completed, the aluminum sheet and strip is usually wound around a sleeve at the outlet of the rolling mill through the rotation of a reel to form a coil. However, in the prior art, during the threading process of the aluminum sheet and strip, due to the relatively thin thickness of the incoming material of the aluminum sheet and strip rolling mill, the head of the aluminum sheet and strip material is easy to sag and top against the equipment during threading, resulting in the problem that it is not easy to thread the head of the aluminum sheet and strip material. When threading the aluminum sheet and strip, workers need to pry and guide the head of the aluminum sheet and strip material to thread it, which affects the production efficiency. Summary of the Invention

[0003] In order to solve the problem that the head of the aluminum sheet and strip material is easy to sag and not easy to thread during the threading of the aluminum sheet and strip in the prior art, the utility model provides a device for bending and warping the head of the aluminum sheet and strip material. This device can jack up the head of the aluminum sheet and strip material upward to make the head of the aluminum sheet and strip material bend and warp, so as to facilitate the threading operation of the aluminum sheet and strip and improve the production efficiency.

[0004] To achieve the above object, the technical solution of the utility model is: a device for bending and warping the head of an aluminum sheet and strip material, including a frame and a feeding roller rotatably arranged on the frame. A pressing roller mechanism is arranged above the feeding roller, and a warping roller mechanism is arranged outside the feeding roller. The pressing roller mechanism can press the head of the aluminum sheet and strip material that needs to perform the threading operation, and the warping roller mechanism can jack up the head of the aluminum sheet and strip material upward to achieve the effect of bending and warping the head of the aluminum sheet and strip material.

[0005] The pressing roller mechanism includes a rotating frame, a pressing roller and a first pushing and pulling assembly. The rotating frame is rotatably arranged inside the frame. L-shaped seats are symmetrically arranged on the outside of the rotating frame, and the pressing roller is rotatably arranged on the outside of the rotating frame. The first pushing and pulling assemblies are arranged on both sides of the frame, and the first pushing and pulling assembly is connected to the L-shaped seat. The first pushing and pulling assembly can drive the rotating frame to rotate downward, and the rotating frame can drive the pressing roller to rotate downward through the L-shaped seat, so that the pressing roller presses against the aluminum sheet and strip, in order to facilitate the warping roller mechanism to jack up the head of the aluminum sheet and strip material.

[0006] The head-raising roller mechanism includes a mounting roller seat, a head-raising roller, and a second pushing and pulling assembly. At both ends of the mounting roller seat, there are fixedly arranged turning plates which are rotatably sleeved on the roller shaft of the feeding roller. The head-raising roller is rotatably arranged in the mounting roller seat. The second pushing and pulling assembly is located below the mounting roller seat and is connected to the mounting roller seat. A head-raising plate is arranged between the head-raising roller and the feeding roller. The second pushing and pulling assembly can drive the mounting roller seat to rotate upward. Under the action of the turning plates, the mounting roller seat can drive the head-raising roller to rotate upward, achieving the effect of the head-raising roller pushing up the head of the aluminum strip. And under the action of the head-raising plate on the head of the aluminum strip, the head of the aluminum strip is bent and raised.

When the piston rod of the first pushing and pulling oil cylinder retracts, it can drive the rotating frame to rotate upward, so as to achieve the purpose of the rotating frame driving the pressing roller to rotate downward and press against the aluminum strip.

[0011] Further, the mounting roller seat has a "U" - shaped structure. At both ends of the mounting roller seat, there are pedestal bearings III. The roller shaft of the head-raising roller is in interference fit with the inner ring of the pedestal bearing III. The mounting roller seat is used for mounting the head-raising roller and driving the head-raising roller to rotate simultaneously.

[0012] Further, the number of the second pushing and pulling assemblies is two. The second pushing and pulling assembly includes a third hinge seat, a fourth hinge seat, and a second pushing and pulling oil cylinder. The third hinge seat is fixedly arranged at the bottom of the mounting roller seat. The piston rod end of the second pushing and pulling oil cylinder is hinged to the third hinge seat and the tail end is hinged to the fourth hinge seat. When the piston rod of the second pushing and pulling oil cylinder extends, it can drive the mounting roller seat to rotate upward, so as to achieve the purpose of the mounting roller seat driving the head-raising roller to rotate upward and push up the head of the aluminum strip.

[0013] Furthermore, the cross-section of the tipping plate is in the shape of an isosceles trapezoid. The two ends of the tipping plate are respectively fixedly connected to the two turning plates, and the tipping plate is located at the top of the turning plates. The tipping plate moves synchronously with the turning plates.
