Description

Technical Field

[0001] This utility model relates to the field of anti-warping structure technology for steel plate cutting, and in particular to an anti-warping guide device for a plate cutting machine. Background Technology

[0002] It is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. Before the production of large structural components, it is necessary to cut the metal sheet into a certain size and then process the cut metal sheet into structural components.

[0003] When cutting metal sheets, the blade moves downwards to cut the sheet. During the cutting process, the cut area is subjected to tremendous pressure, causing the sheet to tend to move upwards away from the cut area. This results in an uneven cut and the sheet is prone to shifting, affecting subsequent processing.

[0004] For example, the anti-tilting guide device for a panel cutting machine disclosed in Chinese Patent Application No. CN202022196687.4 is as follows: The guide device is installed between the feeding roller and the shearing blade of the panel cutting machine. The feeding roller drives the steel plate to be cut forward and feeds it to the shearing blade of the panel cutting machine. After passing the feeding roller, the steel plate tilts upward. The steel plate continues to move forward and enters through the inlet of the guide device. Because the tilting blade at the inlet expands the feeding range, the tilted steel plate can enter the guide device. The steel plate passes through the guide plate, is pressed down under the action of the guide plate, and exits through the outlet of the guide device. Because the gap height between the pressure plate at the outlet and the panel cutting machine is equal to the thickness of the steel plate, the exiting steel plate can be tightly attached to the panel cutting machine. However, this design has the following technical problems:

[0005] First, the gap between the pressure plate at the outlet of the above structure and the cutting machine is equal to the thickness of the steel plate to be cut, which means that it can only press steel plates of a single size. When cutting steel plates of other sizes, the anti-tilting guide device needs to be replaced. It can be seen that the applicable scope of the above structure is relatively small.

[0006] Second, after long-term use, wear will occur between the pressure plate and the steel plate, making it difficult for the pressure plate to press the steel plate tightly, and a new device needs to be replaced. It can be seen that the above structure has low stability for the steel plate. Utility Model Content

[0007] To address the issues of limited applicability and low stability to steel plates mentioned in the background section, this utility model provides the following technical solution:

[0008] A board cutting machine anti-warping guide device includes an anti-warping structure for pressing the steel plate;

[0009] One side of the anti-warping structure is equipped with an adjustment structure for controlling the angle change of the anti-warping structure, and the outside of the anti-warping structure is equipped with a mounting bracket for limiting the anti-warping structure.

[0010] The mounting bracket includes a cylinder for controlling the left and right movement of the adjustment structure.

[0011] The adjustment structure includes a push plate for pushing the anti-tilting structure, and a magnetic block for controlling the up-and-down movement of one side of the anti-tilting structure is obliquely installed on the left side of the push plate.

[0012] Furthermore, connecting plates are installed at both the upper and lower ends of the mounting frame, and multiple mounting holes for fixing the mounting frame to the cutting machine are opened in the middle of the connecting plates.

[0013] Furthermore, a limiting shaft for limiting the anti-tilting structure is installed on the middle left side of the mounting frame, a limiting vertical plate and a limiting horizontal plate for limiting the adjusting structure are installed on the middle right side of the mounting frame, and a baffle for limiting the cylinder is installed at one end of the cylinder.

[0014] Furthermore, the anti-warping structure includes a pressure plate with a U-shaped cross-section. The upper left side of the pressure plate has a limiting hole for limiting the pressure plate in conjunction with a limiting shaft. The upper right side of the pressure plate is provided with a steel block, and multiple square blocks are installed in the middle of the upper end of the pressure plate.

[0015] Furthermore, the push plate has multiple threaded holes on its right side, and a guide edge that abuts against the steel block is provided at the lower left end of the push plate. The guide edge and the magnetic block have the same tilt angle and tilt direction.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. After this utility model is fixed on the plate cutting machine, when the steel plate passes through the mounting frame and is below the anti-tilting structure during the cutting of the steel plate, the cylinder is activated. The cylinder pushes the adjusting structure, causing the guide edge to push the steel block. Under the guidance of the guide edge, the steel block drives the pressure plate to press the steel plate. After the plate cutting machine finishes cutting the steel plate, the cylinder is reset. When the adjusting structure moves in the direction of the cylinder, one side of the pressure plate is raised with the cooperation of the steel block and the magnetic block, releasing the pressure on the steel plate, and the cut steel plate can be taken out.

[0018] Second, this utility model uses an anti-warping structure that can be adjusted in angle, which allows the pressure plate to press steel plates of different thicknesses. Even if wear occurs after long-term use, the pressure plate can still press the steel plate, thereby increasing the service life of this utility model. Attached Figure Description

Detailed Implementation

[0025] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0026] Please see Figures 1-4 This utility model provides a board cutting machine anti-tilting guide device. Through the anti-tilting structure 20 that can be adjusted in angle, the pressure plate 21 can press steel plates of different thicknesses. Even if wear occurs after long-term use, the pressure plate 21 can still press the steel plate, thereby increasing the service life of this utility model.

[0027] This utility model includes an anti-warping structure 20 for pressing a steel plate. An adjustment structure 30 for controlling the angle change of the anti-warping structure 20 is installed on one side of the anti-warping structure 20. An installation frame 10 for limiting the anti-warping structure 20 is installed on the outside of the anti-warping structure 20. The steel plate is placed on the upper part of the bottom plate of the installation frame 10, so that the steel plate is between the bottom plate of the installation frame 10 and the anti-warping structure 20. The bottom plate of the installation frame 10 is at the same height as the belt for conveying the steel plate, so that the steel plate can enter the middle of the installation frame 10. Connecting plates 11 are fixedly installed at the front and rear ends of the upper part and the front and rear ends of the lower part of the installation frame 10. Multiple mounting holes 12 with matching bolts are opened in the middle of the connecting plates 11 to fix the installation frame 10 to the cutting machine. The installation frame 10 is fixed on the two sides of the cutting machine away from the cutting blade, so that the two anti-warping structures 20 press the two sides of the steel plate tightly, preventing the steel plate from warping up on both sides during cutting.

[0028] A limiting shaft 13 for limiting the anti-tilting structure 20 is installed on the middle left side of the mounting frame 10. A limiting vertical plate 14 and a limiting horizontal plate 15 for limiting the adjusting structure 30 are installed on the middle right side of the mounting frame 10. The limiting horizontal plate 15 is located at the upper and lower ends of the adjusting structure 30, and the limiting vertical plate 14 is located on the left and right sides of the adjusting structure 30. The limiting vertical plate 14 and the limiting horizontal plate 15 are fixedly connected, so that the adjusting structure 30 can only move laterally between the two limiting vertical plates 14 and the two limiting horizontal plates 15.

[0029] The mounting bracket 10 includes a cylinder 16 for controlling the adjustment structure 30 to move left and right. One end of the cylinder 16 is equipped with a baffle 17 for limiting the cylinder 16. The baffle 17 is fixedly installed on the upper right side of the mounting bracket 10, so that after the cylinder 16 is started, the extension end of the cylinder 16 drives the adjustment structure 30 to move left and right synchronously.

[0030] The anti-tilting structure 20 includes a pressure plate 21 with a U-shaped cross-section. The upper left side of the pressure plate 21 has a limiting hole 22 for limiting the pressure plate 21 in conjunction with the limiting shaft 13. The limiting shaft 13 is located in the limiting hole 22, allowing the pressure plate 21 to rotate around the limiting shaft 13. The upper right side of the pressure plate 21 is provided with a steel block 24, and the upper end of the steel block 24 is a semi-circular block. The rest of the pressure plate 21 is made of a high-strength alloy that is not magnetically attracted, so that when the adjusting structure 30 moves the anti-tilting structure 20 upward, the steel plate is prevented from being magnetically attracted. Multiple square blocks 23 are fixedly installed at the upper middle part of the pressure plate 21. The setting of multiple square blocks 23 increases the mechanical strength of the pressure plate 21, making the pressure plate 21 less prone to deformation during the process of pressing against the steel plate. When the adjustment structure 30 pushes the steel block 24, the steel block 24 is also less prone to deformation, making the anti-warping function of the pressure plate 21 more stable.

[0031] The adjustment structure 30 includes a push plate 31 for pushing the anti-tilting structure 20. The push plate 31 has multiple threaded holes 32 on its right side. The extension end of the cylinder 16 is fixedly mounted with a flange. The flange is tightened in the threaded hole 32 with bolts, so that when the extension end of the cylinder 16 moves, it drives the push plate 31 to move left and right simultaneously.

[0032] A magnetic block 34 is obliquely installed on the left side of the push plate 31 to control the up-and-down movement of one side of the anti-tilting structure 20. The horizontal height of the left side of the magnetic block 34 is higher than that of the right side. A guide edge 33 is provided at the lower left side of the push plate 31 to abut against the steel block 24. The tilt angle and tilt direction of the guide edge 33 and the magnetic block 34 are the same, so that when the steel block 24 slides on the guide edge 33, the magnetic block 34 and the steel block 24 always maintain a magnetic attraction state. This allows the side of the pressure plate 21 with the steel block 24 to be lifted upward when the push plate 31 moves to the left.

[0033] After this utility model is fixed on the cutting machine, when the steel plate is being cut, when the steel plate passes through the mounting frame 10 and is below the anti-tilting structure 20, the cylinder 16 is activated. The cylinder 16 pushes the adjusting structure 30, so that the guide edge 33 pushes the steel block 24. Under the guidance of the guide edge 33, the steel block 24 drives the pressure plate 21 to press the steel plate. After the cutting machine finishes cutting the steel plate, the cylinder 16 is reset. When the adjusting structure 30 moves in the direction of the cylinder 16, one side of the pressure plate 21 is raised with the cooperation of the steel block 24 and the magnetic block 34, releasing the pressure on the steel plate, and the cut steel plate can be taken out.

[0034] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
