Description

Technical Field

[0001] This invention relates to the field of mast processing technology, particularly to forklift outer masts, specifically a production line and method for processing channel steel for forklift outer masts. Background Technology

[0002] A forklift is an industrial material handling vehicle primarily used for loading, unloading, stacking, and short-distance transport of goods. It is widely used in ports, railway stations, airports, freight yards, factory workshops, warehouses, distribution centers, and other similar locations. The main components of a forklift include a power unit, chassis, working device, hydraulic system, and electrical equipment. Common types of forklifts include internal combustion forklifts (fueled by gasoline, diesel, or liquefied petroleum gas) and electric forklifts (powered by batteries).

[0003] The forklift mast is the main load-bearing structure of the forklift's lifting device. The outer mast is generally composed of two channel steel sections, and it is typically connected to the inner mast via rollers and chains, simultaneously driving the lifting and lowering of the inner mast. For example... Figures 2 to 3 As shown, the roller is usually mounted on the outer frame. To avoid interference between the roller and the outer frame, a notch 18-1 is usually pre-drilled in the channel steel 18. Furthermore, to facilitate the installation of the roller, a roller mounting hole 18-2 is pre-drilled in the channel steel 18. In actual use, the shaft end is often pre-installed in the roller mounting hole 18-2, and then the roller is assembled onto the shaft end. The channel steel 18 also has a connecting hole 18-3, which is usually a threaded hole. An internal limiting device is installed in the threaded hole to prevent the roller from sliding out of the channel steel 18.

[0004] In existing technologies, the processing steps for channel steel are typically as follows: S1. The channel steel 18 is hoisted onto the roller frame by a combination crane, and then the notch 18-1 of the channel steel is cut according to the notch template using a profile cutting machine to ensure the length dimension of the notch 18-1. S2. Then, transfer the channel steel 18 with the notch 18-1 cut to the CNC machining equipment, use the tooling fixture to position and clamp it, and perform milling to finish the surface. S3. Reprogram the machining of roller mounting holes 18-2 on channel steel 18. The opening of roller mounting holes 18-2 needs to be deburred and chamfered. S4. Then, the channel steel 18 is transferred to the radial drilling machine by manual handling or hoisting, positioned and clamped, and the threaded hole 18-3 is machined using a drill bit and tap. S5. Transfer the batch-processed channel steel to the welding workshop and weld the shaft head during the gantry assembly.

[0005] Due to the wide variety of channel steel specifications, the processing steps described above are complex. Specifically, the processing of the channel steel 18 involves flipping (because the notch 18-1 and the roller mounting hole 18-2 are located in different directions) and fixing (i.e., clamping, cutting, drilling, etc.), resulting in low efficiency in producing channel steel that meets the requirements. For example, if 620 channel steels are processed using the above processing method, 15 people are needed per day. This increases labor costs and the production cost of the channel steel, which in turn increases the production cost of equipment such as forklifts that use the channel steel, as well as the user's operating costs. This affects the user experience and is not conducive to the promotion and application of the above processing method in the market. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] Example: Figure 1As shown, a production line for processing channel steel for forklift outer masts is disclosed. The channel steel 18 has a notch 18-1, a roller mounting hole 18-2, and a connecting hole 18-3. The production line includes a machining center 1, a loading station 3, a turning workbench 4, an information display system 6, a machining center 2, a unloading station 9, a turning workbench 2 11, and a flame cutting station 12. The loading station 3 is used for preparing materials for the line. When the channel steel 18 is transported to the loading station 3, the channel steel model to be processed is selected on the information display system 6. Then, the channel steel 18 is transported to the flame cutting station 12 by a handling robot 2 to process the notch 18-1 of the channel steel 18. After the notch 18-1 is processed, the handling robot 2 transports the channel steel 18 to the turning workbench 2 11 to change the direction of the channel steel 18. The handling robot 2 then transports the channel steel 18 to the turning workbench 2 11 to change the direction of the channel steel 18. The aforementioned channel steel 18 is transported to the aforementioned machining center 1 to complete the machining of the aforementioned connecting hole 18-3; after the aforementioned connecting hole 18-3 is completed, the aforementioned channel steel 18 is transported to the turning workbench 4 to realize the turning of the channel steel 18; the aforementioned channel steel 18 after turning is transported to the second machining center 7 to complete the machining of the roller mounting hole 18-2. After the aforementioned channel steel 18 is completed, the aforementioned channel steel 18 is transferred to the aforementioned unloading station 9. It can be seen that the production line of this embodiment integrates multiple devices into one line, and the machining of the notch 18-1, roller mounting hole 18-2 and connecting hole 18-3 of the outer mast channel steel 18 can be completed on this production line. Moreover, its degree of automation is high, so as to realize the automated machining of the channel steel 18, reduce labor costs, improve production efficiency, enhance user experience, and facilitate the promotion and application of the aforementioned production line for machining forklift outer mast channel steel in the market.

[0027] To enable the welding of the channel steel 18 to the shaft head, so that the roller can be subsequently installed at the roller mounting hole 18-2, the production line in this embodiment also includes a conveyor line 8 and a shaft head welding system. The processed channel steel 18 is conveyed to the shaft head welding system via the conveyor line 8. Specifically, the shaft head welding system includes a shaft head feeding system 13, a shaft head handling robot 14, a shaft head welding robot 15, and a shaft head welding fixture 17. The processed channel steel 18 is transported to the shaft head welding fixture 17. The shaft head handling robot 14 uses laser positioning to grasp the shaft head and place it onto the roller mounting hole 18-2 of the channel steel 18. The shaft head welding robot 15 welds the channel steel 18 to the shaft head. The production line also includes a forming press 16. After welding, the channel steel 18 with the welded shaft head is transported to the forming press 16 for shaping to ensure the quality of the channel steel 18.

[0028] In this embodiment, both machining center 1 and machining center 7 are equipped with hydraulic clamps capable of accommodating different types of channel steel 18. These hydraulic clamps securely hold the channel steel 18 to ensure its stability and accuracy during drilling. By incorporating hydraulic clamps in machining center 1 and machining center 7, the production line for processing channel steel for forklift outer masts can be compatible with processing and welding channel steel 18 lengths up to 3.6 meters, thus improving the utilization rate of the production line.

[0029] In this embodiment, the loading station 3 is mainly used to place the channel steel 18 to be processed. The transport robot 2 can transport the channel steel 18 located at the loading station 3 to the processing center 1. The transport robot 2 can automatically complete the transport task of the channel steel 18, reducing the need for manual handling, lowering labor costs, and avoiding errors and safety hazards that may arise from manual operation. The transport robots 2, 5, and 10 are used to transport the channel steel 18 between different stations. The robots can complete the transport task quickly and accurately, significantly improving production efficiency compared to manual handling, ensuring efficient operation of the production line, and enhancing the user experience. The grippers of the transport robots 2, 5, and 10 all use electromagnets to reduce wear on the channel steel 18 and ensure that the grippers can adapt to different models of channel steel 18. The gripper is equipped with a laser displacement sensor and a laser positioner on its side. The laser positioner is used to emit a laser to scan and position the channel steel 18. The laser displacement sensor is communicatively connected to the laser positioner.

[0030] In this embodiment, the production line positions the loading station 3 between machining center 1 and machining center 7. By rationally arranging the production line and connecting it with a transport robot, the logistics path of the entire production line can be optimized, reducing the transportation distance and time of materials on the production line. This layout can also make full use of factory space and avoid space waste caused by unreasonable equipment layout.

[0031] To ensure the orientation of the channel steel 18 during processing meets the requirements for drilling or cutting without manual adjustment, this embodiment utilizes the aforementioned turning worktable 4 and turning worktable 11 to achieve the reversal of the channel steel 18. This is primarily because the notch 18-1, roller mounting hole 18-2, and connecting hole 18-3 are located on different processing surfaces of the channel steel 18. The turning worktables 4 and 11 can quickly adjust the orientation or position of the channel steel 18, reducing rework or readjustment time due to incorrect orientation, thereby improving production efficiency. The turning worktables also allow the channel steel 18 to flow smoothly between different workstations, reducing the complexity of handling robots or conveyor lines 8 and optimizing the logistics path of the entire production line. The conveyor line 8, which can be a conventional conveyor roller, is used to transport the channel steel between different workstations. The conveyor line 8 enables automatic transport of the channel steel between different workstations, reducing the need for manual handling, lowering labor costs, and avoiding potential errors and safety hazards associated with manual handling. Conveyor line 8 can also continuously and stably transport channel steel, ensuring efficient material flow on the production line, reducing waiting time, and improving production efficiency. In this embodiment, conveyor line 8 is located in the middle of the production line to connect various processing and handling stations, ensuring that the channel steel can flow smoothly according to the preset process flow.

[0032] In this embodiment, the unloading station 9 can be located at the lower right corner of the production line, or closer to the lower right corner. The unloading station 9 is used to remove the finished channel steel from the production line; that is, as the end point of the production line, it is responsible for removing the finished channel steel, thereby freeing up space for new channel steel to be processed. This effectively avoids blockage of the production line due to finished product accumulation, ensuring smooth production flow and reducing damage to the channel steel. The unloading station 9 can also collect the finished channel steel centrally for subsequent packaging, inspection, storage, or transportation. Centralized management reduces the dispersion of finished channel steel on the production line and improves management efficiency.

[0033] The aforementioned information display system 6 is used to display real-time status information of the production line, such as equipment operating status, production progress, and fault alarms. The operation panel allows operators to input commands and select processing programs. The aforementioned flame cutting station 12 cuts the channel steel 18 to form the aforementioned notch 18-1 according to the information preset by the aforementioned information display system 6. The preset information includes, but is not limited to, the dimensions of the channel steel 18, the notch 18-1, and the size of the opening on the channel steel 18. The aforementioned information display system 6 includes an operation panel for selecting processing information and displaying the production line status. The operation panel allows operators to input commands and select the required channel steel model. The aforementioned information display system 6 then retrieves the corresponding processing information based on the selected channel steel model.

[0034] The flame cutting station 12 in this embodiment includes a cutting fixture for fixing the position of the channel steel 18 and a cutting robot that can cut the channel steel according to the information preset by the information display system 6. The robot uses a robot program and a flame cutting mold to complete the flame cutting of the channel steel 18, ensuring the cutting size and slag treatment.

[0035] The aforementioned shaft loading system 13 includes a vision system capable of automatically loading shaft components. The vision system identifies the position of the shaft components, and the shaft handling robot then transports them to the shaft welding fixture 17. Different types of shafts are conveyed via the conveyor line 8, where the handling robot performs secondary positioning and grips them onto the roller shaft welding fixture, completing the welding of the shaft to the channel steel. Specifically, the handling robot transports the shaft to the positioning fixture, and then to the channel steel 18 for welding. Shafts are divided into two main categories: directional and non-directional. Directional shafts are identified by the vision system through image capture, transported to the positioning fixture, and then to the channel steel 18 for welding. Non-directional shafts can be directly transported to the channel steel 18 for welding.

[0036] The aforementioned shaft loading system 13 is used for automatically loading shaft head components; the aforementioned shaft head handling robot 14 and the aforementioned shaft head welding robot 15 are used for handling and welding shaft head components; the aforementioned forming press 16 and the aforementioned shaft head welding fixture 17 are used for shaping and welding the shaft heads to complete the fabrication of channel steel. This embodiment describes a production line for processing channel steel for forklift outer masts, featuring a flexible design that is compatible with processing and welding channel steel up to 3.6 meters in length. Some types of channel steel shaft heads may deform after welding; these can be corrected using a 60T press before being removed from the production line.

[0037] The aforementioned shaping press 16 and the aforementioned unloading station 9 are connected by a transport robot 3 10 to achieve unloading.

[0038] This embodiment describes a production line for processing channel steel for forklift outer masts. It integrates a machining center, a loading station, a steering table, an information display system, a machining center, an unloading station, a steering table, and a flame cutting station. The loading station prepares materials for the line. Once the channel steel arrives at the loading station, the desired channel steel type is selected on the information display system. Then, a transport robot transports the channel steel to the flame cutting station to process the notch. After the notch is processed, the transport robot transports the channel steel to the steering table to change its orientation. Finally, the transport robot transports the reoriented channel steel to the machining center. The process involves several steps: 1) completing the machining of the connecting holes; 2) transferring the channel steel to a turning workbench to turn it; 3) transferring the turned channel steel to machining center 2 to machine the roller mounting holes; 4) transferring the channel steel to the unloading station. This production line integrates multiple machines onto a single line, enabling the machining of notches, roller mounting holes, and connecting holes in the outer gantry channel steel. Its high degree of automation effectively increases processing speed while reducing labor costs, thus saving processing costs and reducing user operating costs, improving the user experience, and facilitating the promotion and application of this production line in the gantry machining field.

[0039] A production method for a production line used for machining channel steel for forklift outer masts includes the following steps: S1. Place the channel steel 18 to be processed at the loading station 3; S2. Select the model of the channel steel 18 to be processed on the operation screen of the information display system 6; S3, the handling robot 2 uses image and laser positioning recognition technology to place the channel steel 18 onto the cutting worktable of the flame cutting station 12, and the flame cutting robot cuts the channel steel 18 according to the notch 18-1 data; S4. The handling robot 12 places the channel steel 18 with the notch 18-1 cut onto the turning workbench 14. S5. The handling robot 12 picks up the channel steel 18 on the turning workbench 21 to complete the reversing operation; S6. The handling robot 2 moves the channel steel 18 to the hydraulic clamp of the machining center 1, clamps and positions it, and completes the connection hole 18-3. S7. The handling robot 12 transports the channel steel 18 with the machined connecting holes 18-3 to the turning worktable 14. S8, the transport robot 25 transports the channel steel 18 from the turning workbench 14 to the machining center 27, the hydraulic clamp clamps the channel steel 18, and the roller mounting holes 18-2 are machined on the channel steel 18; S9. The handling robot 25 moves the channel steel 18 from the machining center 27 to the conveyor line 8. The processed channel steel 18 flows into the shaft welding system through the conveyor line 8. S10, the handling robot transports the 18 channel steel to the shaft head welding fixture; S11. The shaft head handling robot uses laser positioning to grab the shaft head onto the channel steel 18, and the shaft head welding robot welds the channel steel 18 to the shaft head. S12. After welding is completed, the transport robot 310 transports the channel steel 18 with the welded shaft head to the shaping press 16 for shaping. S13. After the calibration is completed, the transport robot 310 transports the channel steel 18 to the unloading station 9 for unloading.

[0040] The production line in this embodiment includes the aforementioned production line for processing channel steel for forklift outer masts; it also includes a production line for processing channel steel for inner masts. The aforementioned production line for processing channel steel for inner masts is laid out in the same way as the production line for processing channel steel for forklift outer masts and is symmetrically arranged. The symmetrical arrangement can reduce the transportation distance and time of the channel steel 18 on the production line. The symmetrically distributed outer mast channel steel processing area and inner mast channel steel processing area can also evenly distribute the production tasks to the two areas, avoid overloading of a single processing area, and thus improve the overall production efficiency.

[0041] In this embodiment, the outer gantry channel steel production line and the inner gantry channel steel production line share the forming press 16 and the shaft head welding fixture 17. By sharing the forming press 16 and the shaft head welding fixture 17, duplicate equipment purchases are avoided, thereby reducing equipment investment costs. Furthermore, the shared equipment can be flexibly allocated and used according to the actual needs of the two processing areas, ensuring that the equipment is in working condition most of the time, reducing equipment idle time, and improving the overall utilization rate of the equipment.
