Description

Technical Field

[0001] This utility model relates to the field of material feeding vehicle technology, and in particular to a warm rolling material feeding vehicle. Background Technology

[0002] A four-high reversible warm rolling mill combines the features of a four-high rolling mill and a reversible rolling mill. It's a device that performs rolling processing on metallic materials below their recrystallization temperature. The warm rolling mill maintains a specific temperature during the rolling process. This temperature is typically lower than that of hot rolling but higher than room temperature, hence the name "warm rolling." Warm rolling helps improve the processing properties of materials, reduces deformation resistance, and avoids problems such as excessive oxidation and roughening of the material surface caused by high temperatures. Precise temperature control allows for optimization of the rolling process, improving product quality and performance. Therefore, it places high demands on the equipment.

[0003] In current production processes, manual operation for centering and feeding of titanium coils by operators results in prolonged exposure to air during the process of removing the coils from the natural gas heating furnace and placing them into the coiler. This rapid heat loss prevents the coils from reaching the required rolling temperature, leading to reduced product performance and quality, and increased production costs. Utility Model Content

[0026] Please refer to Figures 1 to 4 This utility model discloses a warm rolling mill feeding trolley, including a main trolley assembly, a secondary trolley assembly, and a transfer assembly. The main trolley assembly includes a main trolley track 1, a main trolley crossbeam 2, a main trolley longitudinal beam 3, and a main trolley wheel set 4. The main trolley track 1 is erected between the starting and ending points of the warm rolling mill feeding trolley. The main trolley wheel set 4 is located at the bottom of the main trolley crossbeam 2. The length direction of the main trolley crossbeam 2 is perpendicular to the length direction of the main trolley track 1. The main trolley crossbeam 2 is mounted on the main trolley track 1 via the main trolley wheel set 4 and can move along the length direction of the main trolley track 1. The main trolley longitudinal beam 3 is fixedly connected to the upper side of the main trolley crossbeam 2, and its length direction is parallel to the length direction of the main trolley track 1. The secondary trolley assembly includes a secondary trolley disc 5, a secondary trolley wheel set 6, and a secondary trolley track 7. The secondary trolley track 7 is located on the upper side of the main trolley crossbeam 2, and its length direction is perpendicular to the length direction of the main trolley track 1. The secondary trolley wheel set 6 is located at the bottom of the secondary trolley disc 5. The trolley pallet 5 is mounted on the trolley track 7 via trolley wheel sets 6, and can move along the length of the trolley track 7. The transfer assembly includes a fixed gantry 8, a movable gantry 9, forks 10, and a drive assembly. The fixed gantry 8 is vertically mounted on the trolley pallet 5. The movable gantry 9 is vertically mounted on the fixed gantry 8. The drive assembly is used to drive the movable gantry 9 to move up and down. The forks 10 are horizontally mounted on one side of the movable gantry 9 along the length of the trolley track 7, and are used for loading and unloading titanium coils.

[0027] For details, please refer to Figure 1 and Figure 2The system comprises two main trolley crossbeams 2 and two main trolley longitudinal beams 3. The two main trolley crossbeams 2 and the two main trolley longitudinal beams 3 are spaced apart and parallel to each other, forming a "well" shape. The main trolley crossbeams 2 and 3 can be fixedly connected by welding. The main trolley longitudinal beams 3 can be made of beams of equal strength to improve the overall load-bearing capacity of the trolley assembly and enhance the safety of the warm rolling feeder during operation. Both the main trolley track 1 and the trolley track 7 can be steel rails. In a preferred embodiment of this invention, steel plates can be welded between the two main trolley crossbeams 2 to further improve the strength of the connection between them.

[0028] There are two main tracks 1. The two main tracks 1 are spaced apart and parallel to each other, corresponding one-to-one with the main beam 2. The main wheel assembly 4 includes two driven wheels and two driving wheels. Each main track 1 has one driving wheel and one driven wheel. The two driving wheels are located on the same straight line parallel to the main beam 2. The two driving wheels can be independent of each other or connected to each other. In a preferred embodiment of this invention, the two driving wheels are rigidly connected, thereby ensuring the synchronization between the two driving wheels and reducing the deviation of the main assembly's movement direction.

[0029] The trolley disc 5 is a rectangular frame. The trolley wheel set 6 includes two trolley drive wheels 61 and two trolley driven wheels 62, which are arranged in a rectangular shape at the bottom of the trolley disc 5. The two trolley drive wheels 61 are located on the same straight line parallel to the main trolley longitudinal beam 3.

[0030] Both the large and small carriage drive wheels 61 can be driven by electric motors. In a preferred embodiment of this invention, each of the two large carriage drive wheels is driven by a large carriage motor, and the two large carriage motors are used in parallel. Each of the two small carriage drive wheels 61 is driven by a small carriage motor, and the two small carriage motors are used in parallel. This improves the synchronization of movement between the two large carriage drive wheels and between the two small carriage drive wheels 61.

[0031] The large and small trolley components need to be precisely positioned and stationary during movement. To ensure that the large and small trolley components can accurately stop at a preset position and remain stationary there, the large trolley wheel assembly 4 also includes a large trolley brake. The large trolley brake is used to limit the movement of the large trolley component. The small trolley wheel assembly 6 also includes a small trolley brake. The small trolley brake is used to limit the movement of the small trolley component. In a preferred embodiment of this invention, both the large trolley brake and the small trolley brake can be electromagnetic brakes. Electromagnetic brakes are contactless braking systems that can be controlled by electrical signals, responding within milliseconds, and have high braking efficiency, thus helping to improve the positioning accuracy of the large and small trolley components.

[0032] Rigid limiting members 21 are provided at both ends of the main beam 2. The rigid limiting members 21 are used to prevent the trolley assembly from detaching from the trolley track 7. The rigid limiting members 21 can be made of steel plates, vertically welded to both ends of the main beam 2, and extend upward to the height of the trolley track 7. When the trolley moves to the ends of the trolley track 7, it will at most collide with the rigid limiting members 21, without falling off the trolley track 7 and causing danger, thereby improving the overall safety of the warm rolling feeder.

[0033] Please refer to Figure 1 and Figure 2 The fixed gantry 8 includes a crossbar 81 and two support columns 82. The two support columns 82 are respectively vertically installed on the upper side of the trolley platform 5, and are respectively located close to both sides of the trolley platform 5 along the length of the main beam 2. The crossbar 81 is fixedly connected between the ends of the two support columns 82 away from the trolley platform 5.

[0034] The fixed mast 8 is shaped like an inverted "C". Chains are installed on the opposite sides of the two support pillars 82, each chain arranged vertically. One side of the fixed mast 8 along the length of the trolley track 7 is used to mount the forks 10, while the other side is fixedly connected to the trolley disc 5 with several reinforcing ribs 83. These ribs enhance the mechanical strength of the fixed mast 8 and also act as counterweights to balance the weight carried by the forks 10. Similarly, reinforcing ribs 83 can also be installed between the forks 10 and the fixed mast 8, forming a stable triangular structure and improving the load-bearing capacity of the forks 10.

[0035] The movable gantry 9 is a rectangular plate with several perforations in the middle to reduce its weight. Sprockets are installed at both ends of the movable gantry 9 along its length. Each sprocket engages with a chain on one of the two support columns 82. This allows the movable gantry 9 to rise and fall under the guidance of the chains via the sprockets. Furthermore, when the movable gantry 9 is suspended, the chains provide support, ensuring safety during its raising and lowering.

[0036] It should be noted that the chain, not shown in the figure, is arranged in a straight line along the vertical direction, rather than forming a loop end-to-end, thus allowing the sprockets to move vertically along the chain. Alternatively, the two chains can be replaced by two vertically arranged slide rails, each positioned on opposite sides of the two supports 82. Correspondingly, the sprockets at both ends of the movable gantry 9 can be replaced by sliders. The sliding engagement between the sliders and the slide rails also guides the raising and lowering of the movable gantry 9.

[0037] The fork 10 includes two or more fork teeth, which are long and straight. One end is fixedly connected to the side of the movable mast 9 opposite to the fixed mast 8, and the other end extends along the movement direction of the trolley assembly. The fork 10 loads or unloads titanium coils by moving the trolley assembly and lifting the movable mast 9, and can transfer the titanium coils loaded on it to other positions by moving the trolley assembly.

[0038] The drive assembly can be a hydraulic cylinder, with its piston rod vertically positioned and its end connected to the movable gantry 9, enabling it to drive the movable gantry 9 to rise and fall. Alternatively, the drive assembly can be a pneumatic cylinder, a motor lead screw, or other similar device.

[0039] Specifically, when the drive assembly uses a hydraulic cylinder, the drive assembly also includes a high-pressure plunger pump, an inlet oil line, a hydraulic lock, and an inlet oil line and a return oil line. The high-pressure plunger pump is connected to the drive cylinder through the inlet oil line and the return oil line, and pumps hydraulic oil to the drive cylinder through the inlet oil line. The hydraulic oil flows back to the high-pressure plunger pump from the drive cylinder through the return oil line. A mesh filter is installed on the inlet oil line. A return oil filter is installed on the return oil line. The mesh filter and the return oil filter are used to clean impurities in the hydraulic oil, ensuring that the drive cylinder is not affected by impurities in the hydraulic oil. In a preferred embodiment of this utility model, a hydraulic lock is installed on the inlet oil line or the return oil line to protect the drive cylinder, prevent hydraulic oil leakage during operation, maintain stable hydraulic oil pressure, and buffer the impact and vibration generated when the piston rod of the drive cylinder moves.

[0040] To improve the working efficiency of the warm rolling mill feeding car, this utility model also includes an electrical control system. The electrical control system includes a PLC system and a human-machine interface. To achieve control of the warm rolling mill feeding car, the main carriage assembly, the auxiliary carriage assembly, and the forks 10 must first be precisely positioned.

[0041] Therefore, in this embodiment, the warm rolling feed trolley also includes a trolley limit switch 11, a trolley limit switch 12, and a fork lifting limit switch 13. The trolley limit switch 11 is located at either end of the trolley crossbeam 2 and is used to position the trolley assembly on the trolley track 1. The trolley limit switch 12 is located at either end of the trolley crossbeam 2 or on any rigid limiting member 21 and is used to position the trolley disc 5 on the trolley track 7. The fork lifting limit switch 13 is located on the top of the fixed mast 8 and is used to position the fork 10 on the fixed mast 8, i.e., the lifting stroke of the fork 10. The trolley limit switch 11, trolley limit switch 12, and fork lifting limit switch 13 can all be replaced by proximity switches or other suitable sensors.

[0042] The PLC system is communicatively connected to the trolley limit switch 11, the trolley limit switch 12, and the fork lifting limit switch 13, and is used for automatic control of the trolley assembly, trolley assembly, and transfer assembly. That is, given a fixed position for the titanium coil and a fixed start and end point for the warm rolling feeder, the PLC system can program the movement sequence and trajectory of the trolley assembly, trolley assembly, and transfer assembly, thereby enabling the PLC system to control the warm rolling feeder to operate automatically.

[0043] The human-machine interface (HMI) is communicatively connected to the trolley limit switch 11, trolley limit switch 12, forklift lifting limit switch 13, and the PLC system. It displays the positions of the trolley assembly, trolley assembly, and transfer assembly, and allows for intervention in their operation via the PLC system. Through the HMI, operators can view the real-time positions and operating status of the trolley, trolley, and transfer components. If a problem is detected, the automatic control of the PLC system can be stopped directly, and the trolley, trolley, and transfer components can be manually controlled, reducing the occurrence of safety accidents.

[0044] The working principle of this utility model's warm rolling feeding trolley is as follows: The trolley assembly drives the fork 10 to extend into the titanium strip in the natural gas heating furnace. The hydraulic cylinder drives the fork 10 to rise, loading the titanium coil onto the fork 10. After loading, the trolley assembly drives the fork 10 to move, removing the titanium coil from the natural gas heating furnace. Then, the main carriage assembly drives the trolley assembly and fork 10 to the coiler. After the main carriage assembly reaches its position, the trolley assembly drives the fork 10 to the designated position on the coiler. Then, the fork 10 descends, unloading the titanium coil into the coiler. After unloading, the trolley assembly drives the fork 10 out of the coiler, and then the main carriage assembly drives the trolley assembly and fork 10 back to the natural gas heating furnace to load the next titanium coil.

[0045] This utility model's warm rolling feeding trolley features a main track 1 positioned between the starting and ending points of the warm rolling feeding trolley, with a main track assembly mounted on the main track 1. A trolley track 7 is mounted on the main track assembly, with its length direction horizontal and perpendicular to the length direction of the main track 1, and a trolley assembly mounted on the trolley track 7. A liftable fork 10 is mounted on the trolley assembly, replacing manual centering and feeding. This significantly reduces the time required to remove titanium coils from the natural gas heating furnace and place them into the coiling machine, thus helping to improve the quality of titanium coil products and reduce the production cost of titanium coils.

[0046] Furthermore, the warm rolling feeding trolley of this utility model can achieve fully automatic feeding through a PLC system, a trolley limit switch 11, a trolley limit switch 12, and a fork lifting limit switch 13, which further improves production efficiency and yield, while reducing the labor intensity of workers and eliminating safety hazards from the equipment level, thus ensuring the personal safety of workers.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
