Description

Technical Field

[0001] This utility model belongs to the field of steel plate feeding technology, and in particular relates to a gantry-type shearing steel plate horizontal feeding device. Background Technology

[0002] Shearing machines are widely used cutting equipment for shearing steel plates, precisely cutting them to meet various industrial processing needs. Among them, gantry shearing machines (referred to as "gantry plate cutters") are widely used in the steel plate processing field due to their stable structure and large processing range. The horizontal feeding equipment used in gantry plate cutters is crucial, as its performance directly affects the positioning accuracy, conveying efficiency, and operational safety of the steel plates.

[0003] Existing traditional horizontal feeding equipment generally uses a gantry feeding robot to place steel plates onto the feeding device in a "top-down" manner, and then pushes them through its own pushing mechanism. However, the lack of effective support for the falling steel plates leads to the following significant drawbacks:

[0004] Insufficient stability of steel plate falling: When the gantry feeding robot places a steel plate, if there is looseness or positioning deviation between the mechanical gripper and the steel plate, the steel plate is prone to fall directly due to gravity, which will not only generate loud noise, but also cause the steel plate to shift in position, affecting the subsequent shearing accuracy.

[0005] Significant safety hazards: If the steel plate is out of control during its descent, it may injure nearby workers, posing a considerable safety risk.

[0006] Excess material handling relies on manual labor: After a single steel plate is cut, there is usually excess material at the end that cannot be further processed. Traditional equipment requires workers to remove it manually, which increases labor costs and may cause the excess steel plate to slip or collide due to improper operation.

[0007] Therefore, it is essential to invent a gantry-type shearing steel plate horizontal feeding device. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a gantry-type horizontal feeding device for steel plates, including a feeding platform, a frame, a lifting hydraulic cylinder, a steel plate pushing mechanism, a linear actuator, a pushing mechanism, an actuator servo motor, a conveying slot, a clearance slot, and conveying wheels. The feeding platform is fixedly installed on the frame, and the output end of the lifting hydraulic cylinder, which is fixedly installed in the middle of the lower part of the frame, is fixed to the steel plate pushing mechanism. A pushing mechanism is installed on the linear actuator, which is fixedly installed in the middle of the feeding platform, and the linear actuator is connected to the actuator servo motor, which is fixedly installed on the feeding platform. Two mirror-symmetrically arranged conveying slots and clearance slots are opened through the feeding platform, and several conveying wheels are rotatably installed in each conveying slot.

[0009] Preferably, the steel plate lifting mechanism includes a base, a negative pressure pipe, an air pump, a support column, and a suction cup. The lower center of the base is fixed to the output end of the lifting hydraulic cylinder. Two mirror-symmetrically arranged negative pressure pipes are installed inside the base, and an air pump is fixedly installed on each negative pressure pipe. A suction cup is provided on the support column fixedly installed above the base, and the suction cup is connected to the negative pressure pipe through the support column.

[0010] Preferably, the base has an "H" shaped structure, and the base is located below the feeding platform. The two negative pressure pipes installed inside the base are parallel and symmetrical to each other.

[0011] Preferably, the support columns fixedly installed on the base are arranged along the axis of the negative pressure pipe, and each negative pressure pipe is connected to several support columns. The suction cups fixedly installed on the support columns can pass through the clearance slots provided on the feeding table and adhere to the lower surface of the steel plate.

[0012] Preferably, the two clearance slots are located between the two conveying slots, and a linear actuator is provided between the two clearance slots.

[0013] Preferably, the pushing mechanism fixedly installed on the linear actuator is allowed to move laterally along its own axis, and the pushing mechanism is allowed to move to a position that does not interfere with the suction cup passing through the clearance slot.

[0014] Preferably, the pushing mechanism includes a pushing platform, a reserve pushing plate, and a pushing cylinder. The pushing platform is connected to a linear actuator. The reserve pushing plate is slidably installed on the inner side of the pushing platform, and the reserve pushing plate is fixed to the output end of the pushing cylinder, which is fixedly installed on the outer surface of the pushing platform.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention features a gantry feeding robot that simultaneously feeds materials from top to bottom. A lifting hydraulic cylinder drives a steel plate lifting mechanism (including suction cups) to actively lift the plate from below the feeding platform from bottom to top, creating a coordinated docking pattern. When the steel plate falls above the clearance slot, the suction cups use negative pressure to adhere to the lower surface of the steel plate, effectively buffering the impact of the fall and preventing the steel plate from falling uncontrollably due to the robot's gripper loosening. This reduces noise and positional deviation, ensuring the steel plate fits smoothly against the feeding platform. Furthermore, the suction force between the suction cups and the lower surface of the steel plate, combined with the support of the conveyor wheels, forms multi-point stable contact. Compared to the traditional method of simply relying on gravity, this significantly improves the initial positioning accuracy of the steel plate, providing a reliable benchmark for subsequent shearing processes.

[0017] The residual pushing plate in the pushing mechanism of this utility model can move axially along the linear actuator under the drive of the pushing cylinder, accurately pushing the residual steel plate after cutting without manual intervention, avoiding the risk of scratches or collisions that may occur when operators come into contact with the residual material, while shortening the loading and unloading interval and improving production efficiency. In addition, the pushing mechanism can move laterally to a position to avoid the suction cup (on the side above the clearance slot), ensuring that when the lifting hydraulic cylinder raises the material, the pushing platform will not obstruct the suction cup from passing through the clearance slot to adsorb the steel plate, realizing the coordinated action of material lifting and residual pushing, and avoiding mechanical structural conflicts.

[0018] The material support mechanism of this utility model actively supports the material from the bottom up, transforming the free fall of the steel plate in the traditional material dropping process into "controlled contact". Even if the gantry robot is briefly unstable, the negative pressure adsorption of the suction cup can immediately fix the steel plate, eliminating the safety hazard of injuring operators or damaging equipment.

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a gantry-type horizontal feeding device for sheared steel plates, including a feeding platform 1, a frame 2, a lifting hydraulic cylinder 3, a steel plate pushing mechanism 4, a linear actuator 5, a pushing mechanism 6, an actuator servo motor 7, a conveying slot 8, a clearance slot 9, and conveying wheels 10. The feeding platform 1 is fixedly installed on the frame 2. The output end of the lifting hydraulic cylinder 3, which is fixedly installed in the middle of the lower part of the frame 2, is fixed to the steel plate pushing mechanism 4. The pushing mechanism 6 is installed on the linear actuator 5, which is fixedly installed in the middle of the feeding platform 1. The linear actuator 5 is connected to the actuator servo motor 7, which is fixedly installed on the feeding platform 1. Two mirror-symmetrically arranged conveying slots 8 and clearance slots 9 are opened through the feeding platform 1. Several conveying wheels 10 are rotatably installed in each conveying slot 8.

[0029] Furthermore, the steel plate lifting mechanism 4 mainly consists of a base 41, a negative pressure pipe 42, an air pump 43, support columns 44, and a suction cup 45. The lower center of the base 41 is fixedly connected to the output end of the lifting hydraulic cylinder 3 by high-strength bolts to ensure stability during lifting. Two parallel negative pressure pipes 42 are symmetrically arranged inside the base 41, made of stainless steel to prevent corrosion during gas delivery. An air pump 43 is fixedly installed on each negative pressure pipe 42, connected to the negative pressure pipe 42 via an air pipe to provide power for generating negative pressure. Two sets of support columns 44 are vertically fixedly installed above the base 41, evenly distributed along the axis of the negative pressure pipe 42. A suction cup 45 is installed at the top of each support column 44, connected to the negative pressure pipe 42 through an internal air passage. When the air pump 43 operates, the suction cup 45 generates negative pressure, adsorbing the lower surface of the steel plate.

[0030] Furthermore, the base 41 is designed with an "H" shape and is made of Q345B low-alloy high-strength steel, possessing excellent resistance to pressure and deformation. The base 41 is located directly below the feeding platform 1. The two negative pressure pipes 42 inside the base 41 are arranged parallel and symmetrically, made of seamless steel pipes to ensure good airtightness. The negative pressure pipes 42 are positioned and supported by welded supports to the inner wall of the base 41, preventing the negative pressure pipes 42 from swaying within the base 41.

[0031] Furthermore, the support columns 44 fixedly installed on the base 41 adopt a cylindrical structure, are made of No. 45 steel and have undergone surface quenching treatment to enhance their wear resistance and strength. The support columns 44 are evenly spaced along the axis of the negative pressure pipe 42, and each negative pressure pipe 42 is connected to a set of support columns 44. The top of each support column 44 is fixedly installed with a suction cup 45 made of rubber, which has good flexibility and adsorption performance. The feeding table 1 has clearance slots 9 corresponding to the positions of the support columns 44 and suction cups 45. The size of the clearance slots 9 is slightly larger than the diameter of the suction cups 45, so that the suction cups 45 on the support columns 44 can pass smoothly through the clearance slots 9 and be tightly adsorbed to the lower surface of the steel plate on the gantry feeding robot.

[0032] Furthermore, two mirror-symmetrical conveying slots 8 and clearance slots 9 are formed through the feeding table 1. Both conveying slots 8 and clearance slots 9 are milled using a CNC machining center to ensure dimensional accuracy and surface roughness. The two clearance slots 9 are located between the two conveying slots 8 and are distributed in parallel. A linear actuator 5 is bolted to the surface of the feeding table 1 between the two clearance slots 9. The linear actuator 5 adopts a combination structure of linear guide rail and ball screw, and is driven by the actuator servo motor 7, enabling precise linear motion.

[0033] Furthermore, the pushing mechanism 6, fixedly mounted on the linear actuator 5, is structurally designed to allow for lateral movement along its own axis. The pushing mechanism 6 is connected to the linear actuator 5 via a slider-guide rail pair. The slider is mounted on the guide rail of the linear actuator 5, and the pushing mechanism 6 is bolted to the slider, ensuring smooth sliding under the drive of the linear actuator 5. When the steel plate lifting mechanism 4 is working, the pushing mechanism 6 can move to a specific position, avoiding interference with the suction cup 45 passing through the clearance slot 9, ensuring that the suction cup 45 can smoothly adsorb and lift the steel plate.

[0034] Furthermore, the pushing mechanism 6 consists of a pushing platform 61, a residual push plate 62, and a pushing cylinder 63. The pushing platform 61 adopts a rectangular frame structure made of aluminum alloy, which reduces weight while ensuring strength. Its bottom is fixedly connected to the slider of the linear actuator 5 by bolts. A linear guide rail is provided on the inner side of the pushing platform 61, and the residual push plate 62 is mounted on the linear guide rail by a slider, allowing it to slide along the inner side of the pushing platform 61. The pushing cylinder 63, fixedly installed on the outer side of the pushing platform 61, is connected to the residual push plate 62 by a pin. When the pushing cylinder 63 works, it drives the residual push plate 62 to perform reciprocating linear motion on the inner side of the pushing platform 61, thereby pushing the residual material after cutting the steel plate out of the feeding table 1, passing through the shearing blade of the shearing machine, and then reaching the receiving mechanism of the shearing machine.

[0035] The working principle is as follows: First, the gantry feeding robot places the steel plate on the feeding platform 1, with the steel plate positioned above the two conveying slots 8 and the clearance slot 9. At this time, the lifting hydraulic cylinder 3 drives the steel plate lifting mechanism 4 to rise, and the suction cup 45 on the base 41 passes through the clearance slot 9 to contact the lower surface of the steel plate. The air pump 43 starts, generating negative pressure through the negative pressure pipe 42 to firmly adhere the steel plate.

[0036] Next, the actuator servo motor 7 drives the linear actuator 5, which in turn moves the pushing mechanism 6 to the appropriate position. After the steel plate is stably attracted by the suction cup 45, the lifting hydraulic cylinder 3 descends, placing the steel plate smoothly on the conveyor wheel 10 and the pushing platform 61 of the pushing mechanism 6. Then, the suction cup 45 releases the negative pressure.

[0037] Then, the actuator servo motor 7 drives the linear actuator 5, which pushes the steel plate on the conveyor wheel 10 toward the shearing blade of the shearing machine via the pushing mechanism 6. After the steel plate is conveyed to the designated position of the shearing machine and the shearing process is completed, the remaining steel plate material stays on the pushing table 61.

[0038] Finally, the cylinder 63 is activated, driving the excess material push plate 62 to push the excess steel plate out of the feeding table 1 along the inner side of the push table 61, and through the shearing blade of the shearing machine, into the receiving mechanism of the shearing machine, completing the entire feeding and excess material handling process.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
