Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal processing equipment, and in particular to a sheet metal trimming machine. Background Technology

[0002] Panel trimming machines are core equipment in the woodworking and furniture manufacturing industry for fine trimming and grooving of panel edges. Current panel trimming machines generally employ a "single-sided processing" structure, meaning that only one edge of the panel can be trimmed in a single setup. When trimming two or all four opposite edges of the panel is required, the operator must manually move and reposition the panel to align the edge to be processed with the cutting tool's working area. This process is not only labor-intensive and inefficient, but also requires repositioning and realigning the panel after movement, leading to increased cumulative errors.

[0003] Furthermore, the fixing mechanisms used to secure the sheet metal in existing equipment (such as vacuum suction cups, pressure rollers, or pneumatic clamps) are typically rigidly installed in predetermined positions on the frame. When the sheet metal's position changes, the fixing mechanism cannot adjust flexibly accordingly, easily leading to insufficient fixing force or misalignment of the fixing points. This can cause the sheet metal to shift, warp, or even fall off, further affecting the trimming quality and posing safety hazards.

[0004] Therefore, there is an urgent need for a new type of board trimming equipment that can reduce labor intensity, improve trimming efficiency, eliminate the need for repositioning, and remain reliably fixed even after the board position changes. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sheet metal trimming machine that can reduce labor intensity and improve trimming efficiency.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A sheet metal trimming machine includes an upper frame, a lower frame, a turntable, a fixing mechanism, and a trimming mechanism;

[0008] The lower support is provided with a boss;

[0009] The boss is provided with an installation space;

[0010] The turntable is rotatably installed in the installation space. The upper surface of the turntable is slightly higher than the upper surface of the boss. The turntable is provided with a vacuum suction hole that communicates with an external vacuum machine and is provided with a sealing ring. The circumferential side of the turntable is provided with an operating part that extends out of the boss for operating the turntable.

[0011] Both the fixing mechanism and the trimming mechanism are mounted on top of the turntable via an upper frame.

[0012] In this technical solution, the sheet material is conveyed to a turntable for trimming. During the trimming process, a fixing mechanism secures the sheet material, while the trimming mechanism trims the edges. After one side is finished, the fixing and trimming mechanisms move away from the sheet material. The operator rotates the turntable via the control unit. If only two opposite sides need trimming, the turntable rotates 180 degrees; if all four opposite sides need trimming, the turntable rotates 90 degrees each time, thus adjusting the sheet material's position. Additionally, during the turntable's rotation, an external vacuum machine operates, firmly adhering the sheet material to the turntable through vacuum suction holes. The angle of the turntable's rotation corresponds to the angle of the sheet material's rotation. This technical solution not only reduces labor intensity and improves trimming efficiency but also eliminates the need for repositioning and realigning the sheet material after adjustment.

[0013] Furthermore, the operating part includes a circular grip and a connector;

[0014] The circular grip is connected to the circumferential side of the turntable via a connector.

[0015] In this technical solution, the turntable is easily rotated by holding a round handle.

[0016] Furthermore, it also includes a locking block;

[0017] The upper surface edge of the turntable is provided with four first grooves that are evenly distributed in a circle, opposite each other, and penetrate through its side.

[0018] The upper surface of the boss is provided with a second groove away from the trimming mechanism;

[0019] The second groove, when the turntable is rotated, cooperates with different first grooves to form a locking groove;

[0020] The locking block can be detachably inserted into the locking slot.

[0021] In this technical solution, only the first and second grooves need to cooperate to form a locking groove, which confirms that the turntable's rotation angle is 90 degrees, 180 degrees, or 270 degrees. Once the turntable has rotated to the desired angle, the locking block is inserted into the locking groove to lock the turntable, preventing it from rotating during edge trimming. When the turntable needs to rotate again, the locking block is removed from the locking groove. This technical solution not only confirms that the turntable's rotation angle is 90 degrees, 180 degrees, or 270 degrees, ensuring that after the turntable rotates, the trimming mechanism processes opposite edges or two other edges without requiring repositioning, but also locks the turntable.

[0022] Furthermore, the upper surface of the turntable is provided with crisscrossing alignment lines.

[0023] In this technical solution, after the sheet material is conveyed to the turntable, it is first aligned by the alignment line. After the alignment is confirmed, the sheet material is fixed by the fixing mechanism to avoid misalignment of the trimming mechanism.

[0024] Furthermore, the fixing mechanism includes a track, a sliding mounting component, a cylinder, and a fixing component;

[0025] The track is fixed on the upper frame;

[0026] The cylinder is slidably connected to the rail via a sliding mounting component;

[0027] The fixing component is installed at the output end of the cylinder.

[0028] In this technical solution, even if the placement of the plate changes, the position can be flexibly adjusted by the cylinder along the track through the sliding mounting parts, so that the plate can remain reliably fixed after the position changes.

[0029] Furthermore, the track is cross-shaped, including longitudinal tracks and transverse tracks, with the intersection of the longitudinal and transverse tracks located directly above the center of the turntable.

[0030] Furthermore, a bearing is provided within the installation space;

[0031] The outer ring of the bearing is fixedly connected to the inner wall of the mounting space;

[0032] The turntable is fixedly connected to the inner ring of the bearing.

[0033] Furthermore, the upper surface of the turntable is covered with a scratch-resistant pad to prevent the turntable from being scratched during the process of feeding or removing the sheet material from the turntable.

[0034] Furthermore, the surface of the circular grip is provided with an anti-slip layer to prevent the hand from slipping during the rotation of the turntable.

[0035] Furthermore, the lower support is provided with conveyor lines located at both ends of the boss, which facilitates the conveying of the sheet material to or from the turntable.

[0036] Compared with existing technologies, the principles and advantages of this technical solution are as follows:

[0037] 1. The sheet material is conveyed to the turntable for trimming. During the trimming process, a fixing mechanism secures the sheet material, while the trimming mechanism trims the edges. After one side is finished, the fixing and trimming mechanisms move away from the sheet material. The operator rotates the turntable via the control unit. If only two opposite sides need trimming, the turntable rotates 180 degrees; if all four opposite sides need trimming, the turntable rotates 90 degrees each time, thus adjusting the sheet material's position. Additionally, during the turntable's rotation, an external vacuum machine operates, firmly adhering the sheet material to the turntable through vacuum suction holes. The angle of the turntable's rotation corresponds to the angle of the sheet material's rotation. This technical solution not only reduces labor intensity and improves trimming efficiency but also eliminates the need for repositioning and realigning the sheet material after adjustment.

[0038] 2. The first and second grooves only need to cooperate to form a locking groove, which confirms the turntable's rotation angle as 90 degrees, 180 degrees, or 270 degrees. Once the turntable has rotated to the desired angle, the locking block is inserted into the locking groove to lock the turntable, preventing it from rotating during edge trimming. When the turntable needs to rotate again, the locking block is removed from the locking groove. This technical solution not only confirms the turntable's rotation angle as 90 degrees, 180 degrees, or 270 degrees, ensuring that the trimming mechanism processes opposite edges or two other edges after the turntable rotates without requiring repositioning, but also locks the turntable.

[0039] 3. Even if the placement of the board changes, the cylinder can be flexibly adjusted along the track by using the sliding mounting parts, so that the board can remain reliably fixed after the position changes. Attached Figure Description

[0048] The present invention will be further described below with reference to specific embodiments:

[0049] like Figures 1 to 5 As shown, the sheet metal trimming machine described in this embodiment includes an upper frame 1, a lower frame 2, a turntable 3, a fixing mechanism 4, a trimming mechanism 5, and a locking block 9;

[0050] The lower support 2 is provided with a boss 6; the boss 6 is provided with an installation space; the turntable 3 is rotatably installed in the installation space, the upper surface of the turntable 3 is higher than the upper surface of the boss 6, the turntable 3 is provided with a vacuum suction hole 7 that is connected to an external vacuum machine and is provided with a sealing ring, and the circumferential side of the turntable 3 is provided with an operating part 8 that extends out of the boss 6 for operating the turntable 3; the fixing mechanism 4 and the trimming mechanism 5 are both mounted on the upper support 1 above the turntable 3.

[0051] Specifically, in this embodiment, the operating part 8 includes a circular handle and a connector; the circular handle is connected to the circumferential side of the turntable 3 through the connector, and the surface of the circular handle is provided with an anti-slip layer to prevent the hand from slipping during the rotation of the turntable 3.

[0052] Specifically, in this embodiment, the upper surface edge of the turntable 3 is provided with four first grooves 10 that are evenly distributed around the circumference, opposite each other, and penetrate through its side; the upper surface of the boss 6 is provided with a second groove 11 that is away from the trimming mechanism 5; the second groove 11 cooperates with different first grooves 10 to form a locking groove when the turntable 3 is rotated; the locking block 9 is detachably inserted into the locking groove.

[0053] Specifically, in this embodiment, the upper surface of the turntable 3 is provided with crisscrossing alignment lines.

[0054] Specifically, in this embodiment, the fixing mechanism 4 includes a track 12, a sliding mounting component, a cylinder 13, and a fixing component 14; the track 12 is fixed on the upper frame 1 and is cross-shaped, including a longitudinal track and a transverse track, the intersection of which is located directly above the center of the turntable 3; the cylinder 13 is slidably connected to the corresponding track 12 (longitudinal track or transverse track) through the sliding mounting component; the fixing component 14 is installed at the output end of the cylinder 13.

[0055] Specifically, in this embodiment, a bearing 15 is provided within the installation space; the outer ring of the bearing 15 is fixedly connected to the inner wall of the installation space; the turntable 3 is fixedly connected to the inner ring of the bearing 15. An anti-scratch pad is laid on the upper surface of the turntable 3 to prevent damage to the turntable 3 during the feeding or removal of materials from it. Conveyor lines 16 located at the front and rear ends of the boss 6 are laid on the lower support 2 to facilitate the feeding or removal of materials from the turntable 3.

[0056] Specifically, in this embodiment, the trimming mechanism 5 is an existing mechanism, including a lateral adjustment module, a longitudinal adjustment module, a front-to-back adjustment module, a drive motor, a mounting base, and a trimming cutter; wherein, the drive motor is mounted on the longitudinal adjustment module via the mounting base (the mounting base is connected to a nut), and the trimming cutter is connected to the output end of the drive motor and is driven to rotate by the drive motor; the front-to-back adjustment module is connected between the lateral adjustment module and the longitudinal adjustment module; the lateral adjustment module, the longitudinal adjustment module, and the front-to-back adjustment module all adopt a screw drive mechanism, and the three work together to drive the drive motor and the trimming cutter to move in the XYZ directions.

[0057] The working principle of this embodiment is as follows:

[0058] The sheet material is conveyed to the turntable 3 via the conveyor line 16 at the front end of the boss 6. It is then aligned using the alignment line. After alignment confirmation, the sheet material is fixed by the fixing mechanism 4 to prevent misalignment of the trimming mechanism 5. After the trimming mechanism 5 completes single-sided trimming of the sheet material, the fixing mechanism 4 and the trimming mechanism 5 are removed from the sheet material. The operator rotates the turntable 3 by holding a circular handle. If only two opposite sides need trimming, the turntable 3 rotates 180 degrees; if all four opposite sides need trimming, the turntable 3 rotates 90 degrees each time, thus adjusting the position of the sheet material. Additionally, during the rotation of the turntable 3, an external vacuum machine operates, firmly adsorbing the sheet material onto the turntable 3 through the vacuum suction holes 7. Therefore, the angle of rotation of the turntable 3 corresponds to the angle of rotation of the sheet material. This embodiment not only reduces labor intensity and improves trimming efficiency but also eliminates the need for repositioning and alignment after the sheet material's position is adjusted.

[0059] During the trimming process, only the first groove 10 and the second groove 11 need to cooperate to form a locking groove to confirm that the rotation angle of the turntable 3 is 90 degrees, 180 degrees, or 270 degrees. When the turntable 3 rotates to the required angle, the locking block 9 is inserted into the locking groove to lock the turntable 3 and prevent it from rotating during the trimming process. When the turntable 3 needs to rotate, the locking block 9 is removed from the locking groove. This embodiment not only confirms that the rotation angle of the turntable 3 is 90 degrees, 180 degrees, or 270 degrees, ensuring that after the turntable 3 rotates, the trimming mechanism 5 processes the opposite edge or two other edges without needing to reposition, but also locks the turntable 3.

[0060] When the fixing mechanism 4 fixes the board (before the board angle is adjusted), the cylinder 13 adjusts its position along the horizontal rail, and the board is fixed by the cooperation of two cylinders 13 slidably connected to the horizontal rail (the two cylinders 13 drive their respective fixing parts 14 to descend). When the board rotates 90 or 270 degrees, the cylinder 13 adjusts its position along the vertical rail, and the board is fixed by the cooperation of two cylinders 13 slidably connected to the vertical rail (the two cylinders 13 drive their respective fixing parts 14 to descend).

[0061] The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all changes made in accordance with the shape and principle of this utility model should be covered within the protection scope of this utility model.
