Abstract
Description
Technical Field
[0001] The utility model relates to a balancing frame structure of a plate rolling machine, in particular to a balancing frame structure of a flange plate rolling machine. Background Art
[0002] The flanges used in large offshore wind turbines need to be rolled into a ring-shaped structure by a plate rolling machine. During the rolling process, the steel is first fed into the plate rolling machine. Under the drive and rolling action of the upper and lower rollers, the steel gradually becomes a ring. Then the support component at one end of the upper roller is flipped, and the ring-shaped steel can be translated from between the upper and lower rollers. At this time, only one end of the upper roller is connected to the frame, and the structure is very unstable. When the support component at the other end is flipped back, it is easy to be unable to accurately align with the support component due to the unstable support of the upper roller. Therefore, a structure is required to keep the upper roller stable when the flipping device is separated from the upper roller. Utility Model Content
[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a balance frame structure of a flange plate rolling machine, which can ensure that the upper pressure roller is kept stable when the turning device is separated from the upper pressure roller.
[0004] To achieve this purpose, the structure adopted by the utility model is: a balancing frame structure of the flange rolling machine, including a base, two groups of lower pressure rollers are symmetrically arranged on the base, each group of lower pressure rollers is connected to a group of motor reducers, a group of upper pressure rollers is arranged above the center of the two groups of lower pressure rollers, a hydraulic lifting cylinder is arranged at the bottom of the upper pressure roller, and brackets are symmetrically arranged on both sides of one end of the upper pressure roller, the brackets are connected to the base, an upper pressure block is arranged in the center of the bracket, the upper pressure block is arranged above the upper pressure roller, and the upper part of the upper pressure block is connected to the bracket through a lower pressure cylinder.
[0005] The bottom of the upper pressing block contacts one end of the upper pressing roller, and the contact surface is in an arc shape. The upper pressing block is arranged above the hydraulic lifting cylinder.
[0006] Two groups of downward pressure oil cylinders are symmetrically arranged above the upper pressure block, and the tops of the two groups of downward pressure oil cylinders are connected to the brackets on both sides through connecting blocks.
[0007] Slide blocks are symmetrically arranged on both sides of the upper pressing block, and slide grooves are arranged at positions corresponding to the slide blocks on the bracket, and the slide blocks are matched with the slide grooves.
[0008] The beneficial effects are: the structural design of the utility model is reasonable and ingenious. When the flipping structure on the plate rolling machine flips away from one end of the upper pressure roller, the upper pressure block presses one end of the upper pressure roller under the action of the lower pressure cylinder to prevent it from shaking and keep it horizontal. When the flipping structure flips back, it can accurately dock with the end of the upper pressure roller. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The present invention will be described by way of examples with reference to the accompanying drawings, in which:
[0010] Figure 1 It is the front view of the utility model. DETAILED DESCRIPTION
[0011] Now the utility model is further described in detail with reference to the accompanying drawings.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0013] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components; the fixed connection can be welding or gluing. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0014] like Figure 1 The balance frame structure of the flange plate rolling machine shown includes a base 1, on which two groups of lower pressure rollers 3 are symmetrically arranged, each group of lower pressure rollers 3 is connected to a group of motor reducers 8, and a group of upper pressure rollers 7 parallel to the lower pressure rollers 3 is arranged above the center of the two groups of lower pressure rollers 3. The bottom of one end of the upper pressure roller 7 is connected to the base 1 through a hydraulic lifting cylinder to achieve the up and down movement of the upper pressure roller 7, and the contact end of the hydraulic lifting cylinder and the upper pressure roller 7 is in an arc shape. Brackets 2 are symmetrically arranged on both sides of the upper pressure roller 7. The bracket 2 is a trapezoidal steel frame structure. An upper pressure block 6 is arranged in the center of the bracket 2. The upper pressure block 6 is arranged above the upper pressure roller 7. The side of the upper pressure block 6 that contacts the upper pressure roller 7 is in an arc shape. The upper pressure block 6 is correspondingly arranged above the hydraulic lifting cylinder. When the upper pressure block 6 is pressed down, it forms a ring with the hydraulic lifting cylinder to wrap one end of the upper pressure roller 7. A downward pressure cylinder 5 is arranged on the top of the upper pressure block 6, and the downward pressure cylinder 5 is connected to the bracket 2 through the connecting block 4. The downward pressure cylinder 5 applies a force to the upper pressure roller 7 corresponding to the hydraulic lifting. Only when the flip structure is separated from the upper pressure roller 7 can the upper pressure roller 7 be kept balanced.
[0015] Two groups of downward pressure cylinders 5 are symmetrically arranged on the left and right sides above the upper pressure block 6. The two groups of downward pressure cylinders 5 can enable the upper pressure block 6 to apply pressure to the upper pressure roller 7 evenly. Since the contact surface between the upper pressure block 6 and the upper pressure roller 7 is arc-shaped, a single downward pressure cylinder 5 cannot enable the two sides of the upper pressure block 6 to apply force to the upper pressure roller 7, and the center of the upper pressure block 6 may be deformed due to excessive pressure.
[0016] Slide blocks are symmetrically arranged on both sides of the upper pressure block 6, and slide grooves are arranged on the corresponding positions of the slide blocks on the two side brackets 2. The slide blocks cooperate with the slide grooves, and the upper pressure block 6 moves up and down along the slide grooves under the action of the downward pressure cylinder 5, so that the movement of the upper pressure block 6 remains stable, and it can also ensure that the force of the upper pressure block 6 is balanced during the downward pressure process, avoiding uneven force application and causing the lower pressure block 6 to wear too quickly.
[0017] The above is based on the enlightenment of this utility model. Through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
