Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, specifically an automatic feeding device for a hydraulic scrap steel shearing machine. Background Technology

[0002] A shearing machine is a type of machine tool that is hydraulically driven, safe, reliable, and easy to operate. Before recycling scrap metal, it is necessary to process the recycled scrap metal by shearing, crushing, etc. This not only facilitates transportation but also makes subsequent processing easier. In order to improve shearing efficiency, a shearing machine is required.

[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: the existing hydraulic scrap steel shearing machine does not have a good feeding function. It is mostly done manually or with the help of tools to place a group of scrap steel plates under the cutter. After the cutting is completed, another steel plate is moved. This cycle is repeated, and the transfer of steel plates one by one takes too much time. It is in urgent need of improvement. Therefore, we propose an automatic feeding device for hydraulic scrap steel shearing machine. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for a hydraulic scrap steel shearing machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for a hydraulic scrap steel shearing machine, comprising a frame, a gantry frame fixedly installed in the middle of the lower surface of the frame, a horizontal plate placed in the top of the frame, and a box fixedly installed in the middle of the inner wall of the top of the frame;

[0006] Liquid cylinders are fixedly installed on both sides of the upper surface of the frame. A support block is fixedly installed at the bottom of the drive shaft of the liquid cylinder. The bottom of the support block is fixedly connected to the horizontal plate. Several sets of uniformly arrayed cutters are fixedly installed on the lower surface of the horizontal plate.

[0007] A support plate is placed at the bottom of the frame, and several sets of uniformly arranged scrap steel plates are placed on top of the support plate.

[0008] A servo motor is fixedly installed on the lower surface of the gantry frame, and a threaded column is fixedly installed on the top of the drive shaft of the servo motor.

[0009] A threaded cylinder is fixedly installed on the lower surface of the support plate. A threaded groove is opened in the middle of the threaded cylinder, and the threaded cylinder is screwed to the threaded column through the threaded groove. It can be used in conjunction with components such as the threaded cylinder, servo motor and support plate. During the use of the feeding device, after each set of scrap steel is cut and the cutter moves up and resets, the cut scrap steel can be pushed down manually. Then, the threaded column can be driven to rotate several times through the drive shaft of the servo motor. The threaded column can drive the threaded cylinder to move up through the threaded groove. The threaded cylinder drives the support plate and scrap steel plate to move up a certain distance, so that the stacked scrap steel plate is fed upward. Compared with the existing method, it can effectively improve the cutting efficiency.

[0010] As an optional solution to the technical solution of this application, a distance sensor and a processor are fixedly installed inside the box, and the probe of the distance sensor extends to the outside of the box. The data output terminal of the distance sensor is connected to the data input terminal of the processor, and the signal output terminal of the processor is connected to the signal input terminal of the servo motor. A wire hole is opened on one side of the rear wall of the box, which can be used in conjunction with the distance sensor and the processor. Whenever a single shearing operation is completed and the horizontal plate moves up, the distance monitored by the distance sensor is less than a set threshold. At this time, the processor issues an instruction to make the servo motor run for a set time, which makes the support plate move up. This cycle can be repeated, so there is no need to manually control the servo motor, reducing the operation steps and further improving the shearing efficiency.

[0011] As an optional solution to the technical solution of this application, an indicator sign is fixedly installed on the front side of one side wall of the frame, and the indicator sign is fixedly connected by welding. The indicator sign can inform personnel of the corresponding operating procedures, making it easier for personnel to understand and use the product, and can also be used to introduce and promote the product.

[0012] As an optional solution to the technical solution of this application, the threaded cylinder is a rectangular block structure, and the shape of the threaded cylinder is adapted to the through-hole contour of the bottom wall of the frame, so that the rectangular block design of the threaded cylinder can be guided by the frame, which meets the requirements of the threaded lifting in this application.

[0013] As an optional solution to the technical solution of this application, support rods are fixedly installed at the four corners of the bottom of the frame, and positioning blocks are fixedly installed at the bottom of the support rods. The device can be stably and detachably limited by passing bolts through the positioning blocks and screwing them into the pre-set threaded structure on the support.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model discloses an automatic feeding device for a hydraulic scrap steel shearing machine. By setting up a threaded cylinder, a servo motor, and a support plate, during the use of the feeding device, after each set of scrap steel is sheared and the cutter moves upward and resets, the cut scrap steel can be pushed down manually. Then, the threaded cylinder can be driven to rotate several times by the drive shaft of the servo motor. The threaded cylinder can drive the threaded cylinder to move upward through the threaded groove. The threaded cylinder drives the support plate and the scrap steel plate to move upward a certain distance, so that the stacked scrap steel plate is fed upward. Compared with the existing method, it can effectively improve the shearing efficiency.

[0016] 2. This utility model discloses an automatic feeding device for a hydraulic scrap steel shearing machine. By setting a distance sensor and a processor, whenever the horizontal plate moves up after a single shearing operation, the distance sensor detects that the distance between the horizontal plate and the shearing plate is less than a set threshold. At this time, the processor issues an instruction to make the servo motor run for a set time, which causes the support plate to move up. This cycle can be repeated, eliminating the need for manual control of the servo motor, reducing operation steps, and further improving shearing efficiency. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1-3This utility model provides a technical solution: an automatic feeding device for a hydraulic scrap steel shearing machine, including a frame 1. Support rods 12 are fixedly installed at the four corners of the bottom of the frame 1. Positioning blocks are fixedly installed at the bottom ends of the support rods 12. Stable and detachable limiting of the device can be achieved by threading bolts through the positioning blocks and connecting them to pre-set threaded structures on the supports. A gantry frame 2 is fixedly installed in the middle of the lower surface of the frame 1. A horizontal plate 4 is placed at the top inside the frame 1. A box 5 is fixedly installed in the middle of the top inner wall of the frame 1. An indicator sign 11 is fixedly installed on the front side of one side wall of the frame 1, and the indicator sign 11 is fixedly connected by welding. The indicator sign 11 can inform personnel of the corresponding operating procedures, facilitating understanding and use, and can also be used to introduce and promote the product. Hydraulic cylinders 42 are fixedly installed on both sides of the upper surface of the frame 1. A support block 43 is fixedly installed at the bottom of the drive shaft of cylinder 42. The bottom of the support block 43 is fixedly connected to the horizontal plate 4. Several sets of uniformly arrayed cutters 41 are fixedly installed on the lower surface of the horizontal plate 4. A support plate 23 is placed at the bottom inside the frame 1. Several sets of uniformly arrayed scrap steel plates 3 are placed on the top of the support plate 23. A servo motor 21 is fixedly installed on the lower surface of the gantry 2. A threaded column 24 is fixedly installed on the top of the drive shaft of the servo motor 21. A threaded cylinder 22 is fixedly installed on the lower surface of the support plate 23. The threaded cylinder 22 has a rectangular block structure. The shape of the threaded cylinder 22 is adapted to the outline of the through-hole of the bottom wall of the frame 1. The rectangular design of the threaded cylinder 22 can be guided by the frame 1, which meets the requirements of the threaded lifting in this application. A threaded groove 25 is opened in the middle of the threaded cylinder 22. The threaded cylinder 22 is screwed to the threaded column 24 through the threaded groove 25.

[0024] In this technical solution, components such as threaded cylinder 22, servo motor 21, and support plate 23 can be used together. During the use of the feeding device, after each set of scrap steel is sheared and the cutter moves upward and resets, the cut scrap steel can be pushed down manually. Then, the threaded column 24 can be driven to rotate several times via the drive shaft of servo motor 21. The threaded column 24 can drive the threaded cylinder 22 to move upward via threaded groove 25. The threaded cylinder 22 drives the support plate 23 and scrap steel plate 3 to move upward a certain distance, so that the stacked scrap steel plate 3 is fed upward. Compared with the existing method, the shearing efficiency can be effectively improved.

[0025] In some technical solutions, a ranging sensor 51 and a processor 52 are fixedly installed inside the housing 5, and the probe of the ranging sensor 51 extends to the outside of the housing 5. The data output terminal of the ranging sensor 51 is connected to the data input terminal of the processor 52, and the signal output terminal of the processor 52 is connected to the signal input terminal of the servo motor 21. A wire hole 53 is opened on one side of the rear wall of the housing 5.

[0026] In this technical solution, components such as the distance sensor 51 and the processor 52 can be used together. Whenever the horizontal plate 4 is moved upward after a single shearing operation, the distance between the distance sensor 51 and the horizontal plate 4 is less than a set threshold. At this time, the processor 52 issues an instruction to make the servo motor 21 run for a set time, which will make the support plate 23 move upward. This cycle can be repeated, so there is no need to manually control the servo motor 21, reducing the operation steps and further improving the shearing efficiency.

[0027] Working principle: It should be noted that this utility model is an automatic feeding device for a hydraulic scrap steel shearing machine. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0028] When using an automatic feeding device for a hydraulic scrap steel shearing machine, the feeding device and shearing machine are placed in the hydraulic scrap steel shearing area, and then the device is connected to an external power source. During this process, the horizontal plate 4 and the cutter 41 can be completely moved down by the hydraulic cylinder 42 to cut the scrap steel plate below for scrap cutting and shearing.

[0029] By incorporating a threaded cylinder 22, a servo motor 21, and a support plate 23, during the feeding device's operation, after each set of scrap steel is sheared and the cutter moves upward and resets, the sheared scrap steel can be manually pushed down. Subsequently, the threaded column 24 can be driven to rotate several times via the drive shaft of the servo motor 21. The threaded column 24 can then drive the threaded cylinder 22 upward via the threaded groove 25. The threaded cylinder 22 drives the support plate 23 and the scrap steel plate 3 upward a certain distance, thus feeding the stacked scrap steel plate 3 upward. Compared to existing methods, this effectively improves shearing efficiency. By incorporating a distance sensor 51 and a processor 52, whenever the horizontal plate 4 moves upward after a single shearing operation, the distance monitored by the distance sensor 51 between the horizontal plate 4 and the distance sensor 51 is less than a set threshold. At this time, the processor 52 issues an instruction to make the servo motor 21 run for a set time, thereby causing the support plate 23 to move upward. This cycle can be repeated, eliminating the need for manual control of the servo motor 21, reducing operational steps, and further improving shearing efficiency.
