Description
Technical Field
[0001] This utility model relates to the technical field of CNC shearing machine components, specifically a material support device for a CNC shearing machine. Background Technology
[0002] A CNC shearing machine is a technologically advanced piece of equipment that achieves precise control through digital instructions composed of numbers, text, and symbols. Its main components include a CNC numerical control system, a position encoder, a hydraulic transmission system, a tool holder, and a frame. The CNC numerical control system and the position encoder form a closed-loop control system to ensure high precision and stability. CNC shearing machines are widely used in the manufacturing of automobiles, airplanes, ships, and other transportation vehicles, as well as in material cutting and processing in industries such as construction, machinery, and electronics.
[0003] Existing material support devices for CNC shearing machines use a carrier plate to support sheet metal (thin plates). The sheet is placed on the carrier plate and then moved to the cutting blade for shearing. However, the sheet may deviate during movement. This could be due to uneven force, speed, or direction during manual movement, causing the sheet to deviate from its intended path, increasing the risk of deviation. Alternatively, the sheet's inherent characteristics—material, thickness, shape, and surface condition—may affect its stability during movement, making some sheets more susceptible to external forces and prone to shifting. Existing material support devices cannot fix the sheet's movement path, leading to potential deviation. This deviation can result in the inability to cut sheets to the required size. To address these issues, we propose a material support device for CNC shearing machines. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a material support device for CNC shearing machines.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] This utility model discloses a material support device for a CNC shearing machine, comprising a support plate with several equally spaced mounting holes on both sides. Two spaced vertical plates are fixed on the support plate, and two spaced limiting plates are provided between the two vertical plates.

A screw is rotatably installed on the top of the front bracket. The upper end of the screw passes through the movable frame and is threadedly connected to the movable frame. A throttle handle is fixed on the top of the screw.
[0008] As a preferred embodiment of this utility model, each side of the vertical plate is provided with a connecting strip, and the connecting strip is fixedly connected to two horizontal bars on the same side.
[0009] As a preferred embodiment of this utility model, one end of the tray is provided with a downwardly inclined guide slope.
[0010] As a preferred technical solution of this utility model, a sliding groove is provided at the top of one end of the tray, a pad that can slide up and down is provided in the sliding groove, and a plurality of elastic elements are provided in the sliding groove at equal intervals, with the upper and lower ends of the elastic elements fixed to the pad and the bottom of the sliding groove, respectively.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model discloses a material support device for a CNC shearing machine, including a support plate 1. The support plate 1 has several equally spaced mounting holes on both sides. Two vertical plates 2 are fixed on the support plate 1 at intervals. Two limiting plates 3 are provided between the two vertical plates 2 at intervals. A crossbar 4 is fixed at both ends of the limiting plate 3. The crossbar 4 passes through the vertical plate 2. A bidirectional screw 5 is rotatably installed between the two vertical plates 2. The bidirectional screw 5 passes through the two limiting plates 3 and is threadedly connected to the limiting plates 3. A turntable 6 is rotatably installed on one side of the vertical plate 2. The rotating shaft of the turntable 6 is fixedly connected to the bidirectional screw 5.
[0026] Mount the tray 1 onto the shearing machine with screws. Refer to the schematic diagram of the device's operation. Figure 1 As shown, the sheet material is placed on the pallet 1 and positioned between two limiting plates 3. The sheet material moves on the pallet 1 towards the cutting blade of the shearing machine. The two limiting plates 3 limit the sheet material on the pallet 1 and prevent it from shifting to the side during movement. By rotating the turntable 6, the bidirectional lead screw 5 is rotated, causing the two limiting plates 3 to move closer or further apart, thereby adjusting the distance between the two limiting plates 3 to accommodate sheet materials of different widths.
[0027] A front bracket 8 is fixed on the tray 1. An upper pressure plate 9 is provided at one end of the tray 1. The upper pressure plate 9 is located between two limiting plates 3. A movable frame 10 that can slide up and down is passed through the front bracket 8. The lower end of the movable frame 10 is fixedly connected to the upper pressure plate 9. A screw 11 is rotatably installed on the top of the front bracket 8. The upper end of the screw 11 passes through the movable frame 10 and is threadedly connected to the movable frame 10. A throttle handle 12 is fixed on the top of the screw 11.
[0028] refer to Figure 4 As shown, the shearing end of the sheet metal is located below the upper pressure plate 9. The upper pressure plate 9 limits the shearing end of the sheet metal to prevent warping, making the shearing amount more precise and improving the yield rate. By rotating the handle 12, the screw 11 is rotated, which moves the upper pressure plate 9 vertically, thereby adjusting the distance between the upper pressure plate 9 and the support plate 1. Therefore, when the thickness of the sheet metal changes, the height of the upper pressure plate 9 can be adjusted to accommodate sheets of different thicknesses.
[0029] Each vertical plate 2 has a connecting strip 7 on one side, which is fixedly connected to two horizontal bars 4 on the same side. The connecting strip 7 limits the horizontal bars 4, preventing them from detaching from the vertical plate 2.
[0030] After one end of the board is cut, by pushing the board to continue moving a certain distance toward the cutter, the uncut board can push the cut board to move until the cut board is removed from the support plate 1.
[0031] One end of the tray 1 is provided with a downwardly inclined guide slope 13. By setting the guide slope 13, the cut sheet material is guided and slides out of the guide slope 13 and can fall into the external storage structure. Therefore, the cut sheet material on the tray 1 can be automatically discharged from the tray 1 without manual removal.
[0032] The pallet 1 has a groove 14 at one top end, within which a sliding pad 15 is installed. Multiple equidistant elastic elements 16 are also installed within the groove 14, with their upper and lower ends fixed to the pad 15 and the bottom of the groove 14, respectively. The pad 15 is positioned above the cutting blade of the shearing machine. During cutting, the pad 15 can retract slightly, simultaneously compressing the elastic elements 16 and protecting the cutting blade. The top of the pallet 1 is polished, allowing for smoother movement of the sheet material on it.
[0033] The system includes a rear support 17 fixed on the support plate 1, a U-shaped plate 18 positioned above the support plate 1 and between two limiting plates 3, a height adjustment mechanism connected to the U-shaped plate 18 for adjusting its height, two spaced friction rollers 19 rotatably mounted inside the U-shaped plate 18, a synchronous belt mechanism 20 connected to the two friction rollers 19 via the synchronous belt mechanism 20, and a motor 21 fixed on the U-shaped plate 18 with its output shaft fixed to one side of the friction roller 19. The height adjustment mechanism includes two spaced vertical rods 22, the lower ends of which are fixed to the U-shaped plate 18 and the upper ends of which pass through the rear support 17. An electric push rod 23 is fixed on the rear support 17, with its output end fixed to the U-shaped plate 18.
[0034] The sheet material on the pallet 1 is placed below the friction roller 19. When the sheet material on the pallet 1 moves, the electric push rod 23 drives the U-shaped plate 18 to move, so that the two friction rollers 19 inside the U-shaped plate 18 come into contact with the sheet material and there is sufficient friction between them. The motor 21 drives the friction roller 19 on one side to rotate. With the transmission of the synchronous belt mechanism 20, the two friction rollers 19 can be driven to rotate synchronously. The friction roller 19 can drive the sheet material to move towards the cutter. The motor 21 works intermittently and can intermittently push a certain length of sheet material to the cutter, thereby replacing manual feeding and being applicable to sheet materials of different thicknesses.
[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
