Description

Technical Field

[0001] This invention relates to the field of steel coil production technology, and in particular to a steel coil turning machine. Background Technology

[0002] In the steel production process, different steps have specific requirements for the placement of steel coils. For example, steel coils processed in a bell-type annealing furnace are usually in an upright position. However, when these coils need to enter the downstream leveling or rewinding units for further processing, they must be changed from an upright to a horizontal position. At this time, the steel coil turning machine undertakes this important task. Through precise and reliable turning actions, it ensures that the steel coils can smoothly adapt to the operational requirements of subsequent processes, ensuring the continuity and efficiency of the entire production process.

[0003] Currently, most widely used steel coil turning machines on the market are electrically driven. While this drive method can meet the basic requirements of steel coil turning to a certain extent, it has many significant drawbacks. On the one hand, due to the enormous mass of the steel coil itself, the turning machine needs to be equipped with a high-power motor to provide sufficient power for smooth turning. The use of high-power motors not only increases the initial purchase cost of the equipment but also places higher demands on the power supply system, requiring a stable power input to ensure the normal operation of the equipment. On the other hand, steel coil turning machines typically need to operate continuously for long periods on the production line, and the prolonged operation of high-power motors results in extremely high energy consumption. This not only leads to a significant increase in production costs but also, in the current context of increasingly scarce energy resources and the promotion of energy conservation and emission reduction, the high-energy-consuming equipment operation mode runs counter to the concept of sustainable development, imposing a heavy economic burden and environmental pressure on enterprises. Summary of the Invention

[0004] The purpose of this invention is to provide a steel coil turning machine to solve the above-mentioned problems existing in the prior art.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A steel coil turning machine includes a main body and a support. The main body includes a truncated cone block with a semi-circular bottom and an L-shaped flip plate horizontally offset from the top of the truncated cone block. The support includes support plates vertically and symmetrically arranged on both sides of the truncated cone block and a U-shaped base horizontally fixedly connected to the bottom of the support plates. A semi-arc rotating shaft horizontally arranged in the middle of the two side walls of the truncated cone block is respectively inserted into the rotating holes of the two support plates. A limiting block is provided at the top of the rotating hole relative to the semi-arc rotating shaft to restrict the main body from rotating counterclockwise from vertical.

[0006] The beneficial effects of this invention are: the round-bottomed truncated cone block and the staggered L-shaped flip plate structure can flip the steel coil, and at the same time, it can automatically return to the correct position; this steel coil flipping machine does not require external motor input power, and uses the gravitational potential energy of the steel coil itself to complete the flipping of the steel coil, which does not consume electricity, saves energy and reduces emissions, and has good economic benefits.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, it also includes a first pad and a second pad corresponding to the L-shaped flap. The inner surfaces of the horizontal and vertical plates of the L-shaped flap are provided with several connecting holes. The first pad is provided with several first countersunk holes corresponding to the connecting holes. The second pad is provided with two slopes that slope downward from the outer side of the plate towards the center line of the plate. A stop strip is provided on one side of the two slopes. Several second countersunk holes are provided on the slopes corresponding to the connecting holes.

[0009] The further beneficial effects of the above-mentioned method are as follows: When flipping the steel coil from a horizontal to a vertical position, a second pad is bolted to the horizontal plate of the L-shaped flip plate, and the stop bar is positioned outside the horizontal plate. A first pad is bolted to the vertical plate of the L-shaped flip plate. The slope of the second pad can help position the steel coil and prevent it from rolling on the horizontal plate. At the same time, the stop bar can prevent the steel coil from sliding outward within the slope. When flipping the steel coil from a vertical to a horizontal position, a first pad is fixed to the horizontal plate of the L-shaped flip plate, and a second pad is fixed to the vertical plate of the L-shaped flip plate, with the stop bar positioned outside the vertical plate. The first and second pads can prevent the steel coil from rolling during flipping, providing a good limiting effect.

[0010] Furthermore, the square-shaped base has a flexible pad on the inner wall of the vertical plate side near the L-shaped flap.

[0011] The further beneficial effect of adopting the above is that the flexible pad can buffer the L-shaped flap, preventing the L-shaped flap from breaking due to the increased local pressure when the steel coil is rolled into place.

[0012] Furthermore, several slots are provided on the side of the frustum block.

[0013] The further beneficial effects of the above are: inserting a counterweight into the slot increases the mass of the bottom of the frustum block, so that although the weight of the frustum block is less than the mass of the steel coil, it is very close. This increases the torque when the frustum block rotates, thereby reducing the relative torque between the steel coil and the frustum block during rotation, reducing the rotational speed of the frustum block, and thus reducing the turning speed of the steel coil, reducing the impact on the flexible pad, and further increasing the safety of the steel coil turning.

[0016] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0017] Example 1 like Figures 1 to 10As shown, a steel coil turning machine includes a main body 1 and a support 2. The main body 1 includes a truncated cone block 11 with a semi-circular bottom and an L-shaped flip plate 12 horizontally offset from the top of the truncated cone block 11. The support 2 includes support plates 21 vertically and symmetrically arranged on both sides of the truncated cone block 11 and a U-shaped base 22 horizontally fixedly connected to the bottom of the support plates 21. Semi-arc rotating shafts 13 horizontally arranged in the middle of the two side walls of the truncated cone block 11 are respectively inserted into the rotating holes 211 of the two support plates 21. A limiting block 212 is provided in the rotating hole 211 with its top relative to the semi-arc rotating shaft 13 to limit the main body 1 from rotating counterclockwise.

[0018] A steel coil 6, which is in a vertical position and has a mass greater than that of the main body 1, is placed on the horizontal plate of the L-shaped flip plate 12. The steel coil 6 drives the L-shaped flip plate 12 and the frustum block 11 to rotate around the rotation hole 211 of the support plate 21 until the vertical plate of the L-shaped flip plate 12 falls horizontally, so that the steel coil 6 is in a horizontal position. The process of changing the steel coil 6 from a horizontal position to a vertical position is the same as above. Due to the round bottom structure of the lower part of the frustum block 11, the mass distribution of the main body 1 is uneven, with the bottom being heavier and the top being lighter. After the steel coil 6 is removed, the frustum block 11 will rotate counterclockwise around the rotation hole 211 to return to a vertical position. The round bottom of the frustum block 11 and the misaligned L-shaped flip plate 12 structure can flip the steel coil 6 and can also automatically return to the vertical position. This steel coil flipping machine does not require external motor input power. It uses the gravitational potential energy of the steel coil 6 itself to complete the flipping of the steel coil 6, which does not consume electricity, saves energy and reduces emissions, and has good economic benefits.

[0019] Example 2 This embodiment is a further improvement on embodiment 1, as detailed below: It also includes a first pad 3 and a second pad 4 corresponding to the L-shaped flap 12. Several connecting holes 121 are provided on the inner side of the horizontal and vertical plates of the L-shaped flap 12. Several first countersunk holes 31 are provided on the first pad 3 corresponding to the connecting holes 121. Two slopes 42 are provided on the surface of the second pad 4, which slope downward from the outer side of the plate towards the center line of the plate. A baffle 43 is provided on one side of the two slopes 42. Several second countersunk holes 41 are provided on the slopes 42 corresponding to the connecting holes 121. When the steel coil 6 is flipped from a horizontal to a vertical position, the second pad 4 is bolted to the horizontal plate of the L-shaped flip plate 12, and the stop bar 43 is positioned outside the horizontal plate. The first pad 3 is bolted to the vertical plate of the L-shaped flip plate 12. The slope 42 of the second pad 4 can help position the steel coil 6 and prevent it from rolling on the horizontal plate. At the same time, the stop bar 43 can prevent the steel coil 6 from sliding outward within the slope 42. When the steel coil 6 is flipped from a vertical to a horizontal position, the first pad 3 is fixed to the horizontal plate of the L-shaped flip plate 12, and the second pad 4 is fixed to the vertical plate of the L-shaped flip plate 12, with the stop bar 43 positioned outside the vertical plate. The first pad 3 and the second pad 4 can prevent the steel coil 6 from rolling during flipping, providing a good limiting effect.

[0020] It should be noted that during the use of the steel coil turning machine, the direction of the steel coil 6 is fixed. It is not necessary to frequently disassemble the first pad 3 and the second pad 4. The steel coil turning machine does not need to alternate between turning the steel coil 6 in two different states.

[0021] Example 3 This embodiment is a further improvement on embodiment 1, as detailed below: The semi-circular rotating shaft 13 is a boss shaft, and the rotating hole 211 is a boss hole. This can enhance the local strength of the shaft and optimize stress distribution, preventing cracks in the shaft due to stress concentration.

[0022] The U-shaped base 22 has a flexible pad 5 on the inner wall of the vertical plate side near the L-shaped flap 12. The flexible pad 5 can buffer the L-shaped flap 12 and prevent the L-shaped flap 12 from breaking due to the increased local pressure when the steel coil 6 is rolled into place.

[0023] The frustum block 11 has several slots 111 on its side. A counterweight is inserted into the slots 111 to increase the mass of the bottom of the frustum block 11. Although the weight of the frustum block 11 is less than the mass of the steel coil 6, it is very close. This increases the torque when the frustum block 11 rotates, thereby reducing the relative torque between the steel coil 6 and the frustum block 11 during rotation, reducing the rotational speed of the frustum block 11, and thus reducing the flipping speed of the steel coil 6. This reduces the impact on the flexible pad 5 and further increases the safety of the steel coil 6 flipping.

[0024] Example 4 This embodiment is a further improvement on any one of embodiments 1 to 3, as detailed below: A reinforcing rib 14 is provided between the horizontal plate of the L-shaped flap 12 and the top of the frustum block 11. This improves the overall strength of the frustum block 11 and the L-shaped flap 12.

[0025] The support plate 21 is triangular, and a step 213 is provided on the hypotenuse of the support plate 21. This facilitates the operator to climb to the top of the support plate 21 to replace the first pad 3 and the second pad 4 and to perform routine equipment maintenance.

[0026] The four corners of the square-shaped base 22 are provided with connecting pieces 23, and the connecting pieces 23 are provided with screw holes 231. The connecting pieces 23 can be welded to the ground or bolted through the screw holes 231; or they can be both welded and bolted, with high connection strength and convenient load transfer.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
