Description

Technical Field

[0001] This utility model relates to a bin tilting mechanism, belonging to the field of mechanical equipment technology. Background Technology

[0002] In the production process of the outer ring of a roller bearing, the billet needs to be rolled into a ring using a ring rolling mill. After being sawn into sections, the round steel is loaded into a material box, which is then transported to the forging workshop. To facilitate the stacking of the material boxes and save space, the base and top corners of the material boxes are designed with supporting structures, see... Figure 1 The bottom of the hopper can cover the top corner, and it can be stacked one on top of the other.

[0003] Since a full hopper of billets typically weighs over two tons, specialized equipment such as overhead cranes, hoists, or forklifts is required to lift the hopper from the bottom, causing it to flip and dump out the billet segments. These segments are then transported to a ring rolling mill for ring production. During the flipping process, one side of the hopper's base acts as a support point, bearing most of the material's weight. This excessive stress on the base leads to severe deformation, causing problems such as the hoppers being unable to be stacked, paint peeling, and requiring frequent repairs, thus increasing maintenance costs.

[0004] Therefore, there is an urgent need for a simple and easy-to-operate bin tilting mechanism that does not damage the bottom of the bin during the tilting and unloading process, thereby reducing maintenance costs. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a simple and easy-to-operate bin flipping mechanism that does not damage the bottom of the bin during the flipping and unloading process, thereby reducing maintenance costs.

[0006] The purpose of this utility model is achieved as follows:

[0007] A hopper tilting mechanism includes a base, a support seat hinged to the base at its bottom via a pin, and a hydraulic cylinder hinged between the bottom of the support seat and the base. The support seat has an L-shaped folded plate structure and includes a vertical plate and a horizontal plate welded together. Two windows are symmetrically arranged at the bottom of the vertical plate to accommodate the bottom feet of the hopper. The horizontal plate is provided with a limiting mechanism to restrict the position of the bottom feet of the hopper, and the bottom of the horizontal plate is provided with a hinge point for the hydraulic cylinder. The hydraulic cylinder pushes the bottom of the horizontal plate, causing the support seat to tilt around the pin.

[0008] Furthermore, the window is a rectangular through-hole structure, the width and height of which are greater than the width and height of a single foot of the loading box, making it convenient for the foot of the loading box to be embedded in the window.

[0009] Furthermore, the limiting mechanism includes two limiting plates symmetrically arranged on the horizontal plate, which limit the position of the bottom feet on both sides of the loading box on the horizontal plate, so that the position of the bottom feet of the loading box corresponds to the window.

[0010] Furthermore, the two limiting plates are parallel long blocks, and the distance between them is greater than the distance between the bottom feet on both sides of the loading box, but less than the distance between the two windows on the vertical plate, ensuring that the bottom feet on both sides of the loading box are located within the two windows; the long blocks are perpendicular to the vertical plate.

[0011] Furthermore, reinforcing plates are welded to the corners of the vertical and horizontal plates.

[0012] Furthermore, the base is equipped with protective nets on three sides to isolate the oil cylinder located inside the base from external operators and equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model uses an oil cylinder to push an L-shaped support base to rotate the material box, embedding the bottom of the material box into the window of the vertical plate of the support base. During the rotation process, the bottom of the material box is no longer solely supported by the support force, but is instead mainly supported by the side of the material box, thus protecting the bottom of the material box from deformation. The overall structure is simple, easy to operate, improves the rotation efficiency, and reduces production costs. Attached Figure Description

[0021] Vertical plate 31, horizontal plate 32, window 33, limiting plate 34, reinforcing plate 35. Detailed Implementation

[0022] See Figures 2-4The present invention relates to a bin tipping mechanism, comprising a base 1, a support seat 3 hinged to the base 1 at its bottom via a pin 2, and a hydraulic cylinder 4 hinged between the bottom of the support seat 3 and the base 1; the three sides of the non-tilting side of the base 1 are provided with protective nets to isolate the hydraulic cylinder 4 located inside the base 1 from external operators and equipment, thereby improving the safety of equipment and personnel.

[0023] The support base 3 has an L-shaped folded plate structure, including a vertical plate 31 and a horizontal plate 32 welded together. A reinforcing plate 35 is welded to the corner of the vertical plate 31 and the horizontal plate 32. Two windows 33 are symmetrically arranged at the bottom of the vertical plate 31 to accommodate the bottom feet of the loading box. Each window 33 is a rectangular through-hole structure, with its width and height both greater than the width and height of a single bottom foot of the loading box, facilitating the insertion of the bottom feet into the window 33. The horizontal plate 32 is provided with a limiting mechanism to restrict the position of the bottom feet of the loading box, including two limiting plates 34 symmetrically arranged on the horizontal plate 32, limiting the position of the two bottom feet of the loading box on the horizontal plate 32, so that the position of the bottom feet of the loading box corresponds to the window 33. In this embodiment, the two limiting plates 34 are parallel long blocks, with a distance between them greater than the distance between the two bottom feet of the loading box, but less than the distance between the two windows 33 on the vertical plate 31, ensuring that the bottom feet of the loading box are both located within the two windows 33. The long blocks are perpendicular to the vertical plate 31.

[0024] The bottom of the horizontal plate 32 is provided with a hinge point 5 for the hydraulic cylinder 4; the hydraulic cylinder 4 pushes the bottom of the horizontal plate 32, causing the support seat 3 to rotate around the pin 2.

[0025] During unloading, a forklift inserts into the bottom of the loading box, lifts the entire loading box, and places it on the horizontal plate 32 of the support base 3, between the two limiting plates 34. The hydraulic cylinder 4 is activated to push the support base 3 to rotate around the pin 2. Under the action of gravity, the loading box automatically slides along the limiting plate 34 towards the vertical plate 31 of the support base 3 until it is blocked by the vertical plate 31. At this time, the bottom of the loading box is embedded in the window at the bottom of the vertical plate 31 and is not subject to additional constraints. The loading box continues to follow the vertical plate 31 to perform a flipping action. The overall weight of the loading box and the blank is gradually borne by the vertical plate 31 and the side of the loading box. The bottom no longer needs to support the entire weight. When the vertical plate 31 reaches a horizontal state and continues to flip downward, the entire weight is borne by the vertical plate 31 and the side of the loading box. At this time, the material in the loading box is automatically poured out of the loading box under the action of gravity, realizing the automatic flipping of the blank while protecting the bottom of the loading box, reducing production costs and improving flipping efficiency.

[0026] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
