Abstract
Description
Technical Field
[0001] This utility model specifically relates to a transverse electromagnetic feeding mechanism for a steel strip in a discharge machine. Background Technology
[0002] In the manufacturing process of cranes, a large amount of steel strips are used. The steel strips need to be precisely cut into different segments. However, the steel strips used in crane production are not only long, but also thick and heavy, making them impossible to load manually using conventional forklifts.
[0003] Currently, traditional material loading typically relies on overhead cranes, wire ropes, and manual hooking, which is cumbersome, slow, requires multiple workers, and poses safety hazards. Furthermore, when using single-point hoisting or simple chain / wire rope lifting, the load is prone to rotation and swaying in the air, leading to inaccurate placement and requiring repeated manual adjustments, thus affecting the smoothness of the automated process. Moreover, it is difficult to ensure that all workpieces are lifted, moved, and lowered synchronously during hoisting, increasing the risk of tilting and slippage accidents. Additionally, after the steel strips are hoisted and placed on the loading platform, their positions may be uneven, requiring subsequent manual alignment or adjustment before proceeding to the next process. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a transverse electromagnetic feeding mechanism for steel belts in a discharge machine.
[0005] The technical solution adopted by this utility model to solve its technical problem is: A transverse electromagnetic feeding mechanism for a steel strip discharge machine includes a transversely moving feeding gantry, a storage platform located below the feeding gantry, and a feeding platform located below the feeding gantry and placed parallel to the storage platform. The feeding gantry includes a gantry moving rack bolted to a concrete floor, a gantry moving slide rail bolted to the concrete floor and parallel to the gantry moving rack, a gantry body assembled with the gantry moving slide rail, a displacement motor bolted to the feet of the gantry body and engaged with the gantry moving rack by gears, several sets of cable lifting devices mounted on the gantry body, two square tubes fixedly mounted to the cable lifting devices and movable by the cable lifting devices, and electromagnetic chucks equidistantly arranged on the square tubes and fixed by mounting bases.
[0006] Preferably, the cable lifting device includes a servo motor fixedly installed with the gantry frame, a four-layer winch installed below the servo motor, four steel cables wound by the four-layer winch, a pulley block fixedly installed with the gantry frame for guiding the steel cables, a lifting pipe for fixing and installing the square tube and for stable lifting using the four steel cables, and a guide column welded to the lifting pipe at its lower end and fixedly installed with the gantry frame at its upper end via a positioning plate.
[0007] Furthermore, the pulley block includes a cable-exiting smooth pulley near the fourth-layer winch and fixedly mounted on the gantry frame using bolts and brackets; a first guide cable pulley near the cable-exiting smooth pulley and fixedly mounted on the gantry frame using bolts and brackets; and a second guide cable pulley located directly above the hoisting pipe and fixedly mounted on the gantry frame using bolts and brackets.
[0008] Preferably, the loading platform includes a frame, several platens welded onto the frame, and a lateral pushing device located between two platens and fixedly installed via the frame.
[0009] Furthermore, grooves are evenly spaced on the stand.
[0010] Furthermore, the lateral pushing device includes two lateral moving guide rails fixedly mounted on the frame by bolts, a lateral rack fixedly mounted on the frame and located between the two lateral moving guide rails by bolts, a lateral moving slide plate with a slider at the bottom cooperating with the lateral moving guide rails, a lateral moving motor fixedly mounted on the lateral moving slide plate and with a gear meshing with the lateral rack at the output end, a mounting base fixedly mounted on the lateral moving slide plate, a lateral pushing cylinder fixedly mounted by the mounting base, and a pushing plate fixedly mounted on the output end of the lateral pushing cylinder.
[0011] The beneficial effects of this utility model are as follows: 1. This mechanism achieves fully automated operation of the steel strip from the storage platform to the loading platform through the lateral movement of the loading gantry, the lifting of the electromagnetic chuck, and the coordination of the lateral pushing device. This reduces manual intervention and significantly improves the loading speed and overall production efficiency. In addition, the displacement motor drives the gantry to move on the rack and slide rail, ensuring fast and accurate positioning. The electromagnetic chuck enables rapid picking and placing of workpieces by turning on and off the power, which is simple to operate and responds quickly. Moreover, the cable lifting device uses a servo motor to drive a four-layer winch. The four steel cables work in conjunction with the cable delivery smooth pulley, the first guide cable pulley, and the second guide cable pulley to achieve synchronous winding and unwinding, ensuring the stability of the electromagnetic chuck during the lifting process. This avoids the steel strip from shaking, tilting, or falling during transportation, improving operational safety. The structural design of the guide column and lifting tube further enhances the stability of the lifting process and prevents lateral swaying. 2. The coordination of the gantry's moving rack and slide rail, along with the precise control of the displacement motor, enables the gantry to accurately move to the target positions on the storage platform and loading platform, meeting the requirements for high-precision loading. The electromagnetic chucks are arranged equidistantly on the square tube via mounting bases, and their position or number can be adjusted according to the size and shape of the steel strip to adapt to the loading requirements of different workpieces, offering high flexibility. The lateral pushing device, driven by the lateral moving guide rail, rack, and motor, achieves precise positioning and pushing of the pushing plate, ensuring that the steel strip is neatly arranged on the loading platform.

[0012] Figure 1 This is an assembly drawing of a transverse electromagnetic feeding mechanism for a discharge machine according to the present invention; Figure 2 for Figure 1 Structural diagram of the loading and unloading gantry frame; Figure 3 for Figure 2 Structural diagram of the cable lifting device; Figure 4 for Figure 1 Structural diagram of the upper and middle feeding platforms; Figure 5 for Figure 4 Exploded view of the middle lateral feeding device. Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.
[0014] Example like Figure 1 As shown, a transverse electromagnetic feeding mechanism for a steel strip discharge machine includes a transversely moving feeding gantry 1, a storage platform 2 located below the feeding gantry 1, and a feeding platform 3 located below the feeding gantry 1 and placed side by side with the storage platform 2. Specifically, the layout of the feeding gantry 1, storage platform 2, and feeding platform 3 optimizes the complete automated process from material picking and handling to material unloading, replacing inefficient manual hoisting and laying the foundation for high-efficiency production.
[0015] like Figure 2-3 As shown, the loading gantry 1 includes a gantry moving rack 11 bolted to the cement floor, a gantry moving slide rail 12 bolted to the cement floor and parallel to the gantry moving rack 11, a gantry body 13 assembled with the gantry moving slide rail 12, a displacement motor 14 bolted to the feet of the gantry body 13 and meshing with the gantry moving rack 11 via gears, several sets of cable lifting devices 15 mounted on the gantry body 13, two square tubes 16 fixedly mounted to the cable lifting devices 15 and movable by the cable lifting devices 15, and electromagnetic chucks 17 equidistantly arranged on the square tubes 16 and fixed by mounting bases.
[0016] It should be further explained that the combination of the gantry moving rack 11 and the displacement motor 14 provides a moving method with large driving force and precise positioning, ensuring that the entire gantry body 13 can stably and accurately move back and forth between the storage platform 2 and the loading platform 3 over long distances while carrying heavy objects. The gantry moving slide rail 12 ensures the smoothness of the movement process. The electromagnetic chuck 17 is used as the actuator, which magnetically picks up the steel strip, avoiding surface indentations, scratches, or deformation that may be caused by mechanical clamps. It is particularly suitable for plates or coils with high surface quality requirements. In addition, more importantly, several sets of cable lifting devices 15 drive two square tubes 16, and the electromagnetic chucks 17 are arranged at equal intervals and fixed by the mounting base. In fact, the number and spacing of the electromagnetic chucks 17 can be adjusted according to steel strips of different sizes and shapes, enhancing the versatility of the equipment.
[0017] The cable lifting device 15 includes a servo motor 151 fixedly installed with the gantry frame 13, a four-layer winch 152 installed below the servo motor 151, four steel cables 153 wound by the four-layer winch 152, a pulley block 154 fixedly installed with the gantry frame 13 for guiding the steel cables 153, a lifting pipe 156 for fixing and installing the square tube 16 and for stable hoisting by the four steel cables 153, and a guide column 157 with its lower end welded to the lifting pipe 156 and its upper end fixedly installed with the gantry frame 13 by a positioning plate. Specifically, the servo motor 151 drives the four-layer winch 152, and the four steel cables 153 synchronously lift the rigid hoisting pipe 156, forming a stable four-point hoisting. This solves the tilting and swaying problems that are easy to occur in single-point or double-point hoisting, which is crucial for ensuring that the long steel strip remains horizontal during the lifting process. In addition, the guide column 157 is connected to the gantry frame 13 through the positioning plate, providing a rigid vertical guide for the entire cable lifting device 15, effectively preventing it from swinging and rotating in the horizontal direction, and further improving the stability and positioning accuracy of the lifting.
[0018] The pulley block 154 includes a cable-exiting smooth pulley 1541 near the fourth-layer winch 152 and fixedly mounted on the gantry frame 13 with bolts and brackets; a first guide cable pulley 1542 near the cable-exiting smooth pulley 1541 and fixedly mounted on the gantry frame 13 with bolts and brackets; and a second guide cable pulley 1543 located directly above the hoisting pipe 156 and fixedly mounted on the gantry frame 13 with bolts and brackets. Specifically, the steel cable 153 is released from the fourth-layer winch 152 and passes through the cable-exiting smooth pulley 1541, the first guide cable pulley 1542, and the second guide cable pulley 1543 in sequence before being assembled with the hoisting pipe 156 via clamps. When the servo motor 151 drives the fourth-layer winch 152, it can simultaneously wind and unwind four steel cables 153 to smoothly raise and lower the hoisting pipe 156, thereby driving the electromagnetic chuck 17 installed on the square tube 16 to smoothly raise and lower.
[0019] It should be further explained that the electromagnetic chuck 17 is a device that generates magnetic force by energizing an internal coil, which then passes through a magnetically conductive panel to firmly hold the workpiece in contact with the panel surface. When the coil is de-energized, the magnetic force disappears, thus demagnetizing the workpiece and allowing it to be picked up or put down.
[0020] like Figure 4-5 As shown, the loading platform 3 includes a frame 31, several platen 32 welded onto the frame 31, and a lateral pushing device 33 located between two platen 32 and fixedly installed via the frame 31. The lateral pushing device 33 is installed on the frame 31 so that when the steel strip is placed on the platen 32 but its position is slightly uneven, the lateral pushing device 33 can automatically push it to a reference position.
[0021] The frame 31 has grooves 311 evenly spaced on it. Specifically, the frame 31 can be used to install the table plate 32 at intervals through the grooves 311, and the grooves 311 can be used to assemble the lateral pusher device 33.
[0022] The lateral pushing device 33 includes two lateral moving guide rails 331 bolted to the frame 31, a lateral rack 332 bolted to the frame 31 and located between the two lateral moving guide rails 331, a lateral moving slide plate 333 with a slider at the bottom cooperating with the lateral moving guide rails 331, a lateral moving motor 334 fixedly mounted on the lateral moving slide plate 333 and with a gear meshing with the lateral rack 332 at its output end, a mounting base 335 fixedly mounted on the lateral moving slide plate 333, a lateral pushing cylinder 336 fixedly mounted on the mounting base 335, and a pushing plate 337 fixedly mounted on the output end of the lateral pushing cylinder 336. Specifically, the combination of the lateral moving guide rail 331, the lateral rack 332, and the lateral moving motor 334 enables the lateral moving slide plate 333 to move precisely to a preset pushing starting position in the horizontal direction with the lateral pushing cylinder 336, adapting to steel strip workpieces of different widths. The lateral pushing cylinder 336 drives the pushing plate 337 to complete the final pushing action. In addition, the lateral pushing cylinder 336 operates smoothly and has a constant pushing force, which can ensure that the steel strip is pushed into place while avoiding damage to the workpiece or equipment due to excessive impact force.

All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of this utility model, shall fall within the scope of protection of this utility model.
