Description

Technical Field

[0001] This invention relates to the field of grooving machine technology, and more specifically, to a grooving machine for bending aluminum composite panels. Background Technology

[0002] Aluminum composite panels are a new type of material with the characteristics of being lightweight, high-strength, beautiful, waterproof, fireproof, weather-resistant, and easy to process. However, aluminum composite panels are easy to break when bent directly, so they must be grooved before bending. When bending aluminum composite panels in large quantities, grooving is usually done by an automated grooving machine. However, for factories with low production volume, grooving of small batches of aluminum composite panels is usually done manually, with workers using hand saws to cut and groove the marked positions on the aluminum composite panels. However, when workers are cutting grooves, the hand saw is prone to shaking, which can cause inconsistent groove depths and affect the accuracy of the grooving. Summary of the Invention

[0003] To address the problem that hand-held saws tend to wobble during grooving, leading to inconsistent grooving depths and affecting grooving accuracy, this invention provides a grooving machine for bending aluminum composite panels.

[0004] This invention provides a grooving machine for bending aluminum composite panels, including a hand-held saw, a T-shaped plate, an L-shaped plate, an extrusion plate, a lifting mechanism, and a limiting mechanism. The hand-held saw is detachably mounted on the T-shaped plate and moves back and forth linearly along the length of the T-shaped plate. The lifting mechanism is connected to the end of the T-shaped plate and is used to drive the L-shaped plate, which is aligned with the cutting wheel of the hand-held saw, to rise and fall vertically relative to the T-shaped plate and fix its position. The limiting mechanism is located at the upper end of the L-shaped plate and is used to drive the extrusion plate, which is located inside the L-shaped plate, to slide outward or retract inward.

[0005] Optionally, a mounting plate is fixedly installed at the bottom of the hand-held saw motor, and a sleeve plate is fixedly connected to the side of the mounting plate. The outer side of the T-shaped plate is slidably connected to the inner surface of the sleeve plate and the sizes are matched.

[0006] Optionally, the lifting mechanism includes a connecting plate, an L-shaped frame, a sleeve, a rotating ring, a drive tube, and a first handle. The end of the connecting plate is fixedly connected to the end of the T-shaped plate, and the connecting plate and the T-shaped plate are perpendicular to each other. The side of the L-shaped plate is slidably connected to the side of the connecting plate away from the T-shaped plate. The sleeve is fixedly mounted on the middle of the upper surface of the L-shaped plate. The rotating ring is rotatably connected to the inner surface of the sleeve. The bottom end of the drive tube is fixedly connected to the middle of the upper end of the rotating ring. The first handle is fixedly mounted on the outer side of the upper end of the drive tube. The L-shaped frame is fixedly mounted at the edge of the upper surface of the connecting plate. The drive tube is internally threaded to the L-shaped frame. The L-shaped plate drives the limiting mechanism to lift vertically synchronously.

[0007] Optionally, the limiting mechanism includes a drive rod, a rotating head, a piston plate, a groove, and a second handle. The L-shaped plate has an L-shaped cavity that communicates with the outside. The piston plate is slidably connected to the inner side of the vertical section of the L-shaped cavity. The groove is located in the middle of the upper surface of the piston plate. The drive rod passes through the rotating ring and the inner side of the drive tube and is threadedly connected to the middle of the upper surface of the L-shaped plate. The rotating head is fixed to the bottom end of the drive rod and is rotatably connected to the inner surface of the groove. The second handle is fixed to the outer side of the upper end of the drive rod. The piston plate is vertically raised and lowered to drive the extrusion plate to slide outward or retract inward.

[0008] Optionally, the L-shaped cavity is divided into a first chamber and a second chamber by a piston plate. The first chamber is filled with hydraulic oil, and a pressing plate is horizontally slidably connected to the inner wall of the first chamber. A plurality of evenly distributed springs are fastened between the inner end face of the pressing plate and the inner side wall of the first chamber.

[0009] Optionally, an anti-slip pad is attached to the outer end face of the extrusion plate.

[0010] Optionally, the upper surface of the L-shaped plate is provided with symmetrical circular holes on both sides, and the circular holes are connected to the second chamber.

[0011] Optionally, the outer surface of the L-shaped plate is on the same plane as the mounting surface of the hand saw cutting wheel.

[0012] Optionally, multiple T-shaped plates can be spliced ​​together end to end, with a stud fixed at one end of each T-shaped plate and a matching threaded hole at the other end.

[0013] The advantages of the grooving machine for bending aluminum composite panels of this invention are as follows: Due to the different thicknesses of aluminum composite panels, the depth and width of the grooving vary. After changing the cutting wheel of the hand saw, the operator first marks the position where the aluminum composite panel needs to be grooved. Then, the hand saw is used to groove one end of the marked line along the marked line. Then, the relative vertical position of the L-shaped panel is adjusted and the extrusion plate is driven to slide outwards to make the L-shaped panel clamp and fix it in the pre-grooved area. Then, the hand saw is moved along the length of the T-shaped panel to stabilize the cutting groove, avoiding inconsistent cutting groove depth caused by the shaking of the hand saw, thus improving cutting accuracy. In addition, the T-shaped panel has a compact structure, is easy to disassemble and carry, and is suitable for various cutting environments. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0020] like Figure 1-8 As shown, this embodiment of the invention provides a grooving machine for bending aluminum composite panels, including a hand-held saw 100, a T-shaped plate 202, an L-shaped plate 301, an extrusion plate 502, a lifting mechanism, and a limiting mechanism. The hand-held saw 100 is detachably installed on the T-shaped plate 202 and moves back and forth linearly along the length of the T-shaped plate 202. The lifting mechanism is connected to the end of the T-shaped plate 202 and is used to drive the L-shaped plate 301, which is aligned with the cutting wheel of the hand-held saw 100, to rise and fall vertically relative to the T-shaped plate 202 and fix its position. The limiting mechanism is set at the upper end of the L-shaped plate 301 and is used to drive the extrusion plate 502, which is set inside the L-shaped plate 301, to slide outward or retract inward.

[0021] In this embodiment, grooving is required before bending the aluminum composite panel. The worker first marks the desired grooving position on the aluminum composite panel, then uses a hand saw 100 to groove one end along the marked line. Next, a T-shaped plate 202 is placed on the upper surface of the aluminum composite panel. Then, a lifting mechanism drives an L-shaped plate 301 to move vertically downwards relative to the T-shaped plate 202. The movement of the L-shaped plate 301 is stopped when its bottom end contacts the inner bottom surface of the grooved area. The L-shaped plate 301 is fixed relative to the T-shaped plate 202. Then, the position of the T-shaped plate 202 is slightly adjusted horizontally so that the side of the L-shaped plate 301 fits against the inner side of the groove. Next, the limiting mechanism drives the extrusion plate 502 inside the L-shaped plate 301 to slide outwards, pressing it against the inner side of the groove. At this point, the L-shaped plate 301 and the extrusion plate 502 are firmly fixed by pressing against the inner side of the groove. The T-shaped plate 202 is now fixed relative to the aluminum composite panel. Next, the hand saw 1... The L-shaped plate 202 is installed on the T-shaped plate 202. Then, the operator holds the handle of the hand saw 100 and moves the hand saw 100 in a straight line along the length of the T-shaped plate 202. That is, the cutting wheel of the hand saw 100 moves along the scribing trajectory to groove the remaining part of the scribing. By pre-cutting a small section of groove and fixing the position of the T-shaped plate 202 with the pre-cut groove as a reference, the hand saw 100 can be moved along the length of the T-shaped plate 202 to stabilize the cutting groove and avoid inconsistent cutting groove depth caused by the shaking of the hand saw 100, thereby improving the cutting accuracy. In addition, the T-shaped plate 202 is compact, easy to disassemble and carry, and suitable for various cutting environments. Since the depth and width of the groove are different due to the different thicknesses of the aluminum composite panels, after changing the cutting wheel of the hand saw 100, the relative vertical position of the L-shaped plate 301 can be adjusted according to the above method, and the position of the T-shaped plate 202 can be fixed by cooperating with the drive extrusion plate 502 to slide outward, so as to stabilize the cutting of grooves of different depths and widths as required. Due to the varying thicknesses of aluminum composite panels, the depth and width of the grooves differ. After replacing the cutting wheel of the hand-held saw 100, the operator first marks the area on the aluminum composite panel where the groove needs to be cut. Then, the hand-held saw 100 cuts the groove along the marked line. Next, the relative vertical position of the L-shaped plate 301 is adjusted, and the drive extrusion plate 502 slides outward to lock and fix the L-shaped plate 301 into the pre-grooved groove. Then, the hand-held saw 100 is moved along the length of the T-shaped plate 202 to stabilize the cutting groove, avoiding inconsistent groove depths caused by the hand-held saw 100 shaking, thus improving cutting accuracy. Furthermore, the T-shaped plate 202 is compact, easy to disassemble and carry, and suitable for various cutting environments.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, optionally, a mounting plate 200 is fixedly installed at the bottom of the motor part of the handheld saw 100, and a sleeve plate 201 is fixedly connected to the side of the mounting plate 200. The outer side of the T-shaped plate 202 is slidably connected to the inner surface of the sleeve plate 201 and the sizes are matched.

[0023] In this embodiment, by fitting the inner side of the sleeve plate 201 onto the outer side of the T-shaped plate 202, the hand-held saw 100 is easy to disassemble and install. When the T-shaped plate 202 is attached to the upper surface of the aluminum composite panel and its relative position is fixed, the hand-held saw 100 can be moved back and forth along the length of the T-shaped plate 202. Since the outer side of the T-shaped plate 202 is slidably connected to the inner surface of the sleeve plate 201 and their sizes match, the bottom end of the mounting plate 200 slides against the upper surface of the aluminum composite panel when the hand-held saw 100 moves, ensuring that the hand-held saw 100 moves stably.

[0024] like Figure 4 , Figure 5 and Figure 6 As shown, optionally, the lifting mechanism includes a connecting plate 203, an L-shaped frame 300, a sleeve 302, a rotating ring 303, a drive tube 304, and a first handle 305. The end of the connecting plate 203 is fixedly connected to the end of the T-shaped plate 202. The connecting plate 203 and the T-shaped plate 202 are perpendicular to each other. The side of the L-shaped plate 301 is slidably connected to the side of the connecting plate 203 away from the T-shaped plate 202. The sleeve 302 is fixedly installed in the middle of the upper end face of the L-shaped plate 301. The rotating ring 303 is rotatably connected to the inner surface of the sleeve 302. The bottom end of the drive tube 304 is fixedly connected to the middle of the upper end of the rotating ring 303. The first handle 305 is fixedly installed on the outer side of the upper end of the drive tube 304. The L-shaped frame 300 is fixedly installed at the edge of the upper end face of the connecting plate 203. The drive tube 304 is internally threadedly connected to the L-shaped frame 300. The L-shaped plate 301 drives the limiting mechanism to lift vertically synchronously.

[0025] In this embodiment, the T-shaped plate 202 and the L-shaped plate 301 are connected by the connecting plate 203, and at this time the L-shaped plate 301 and the T-shaped plate 202 are parallel to each other. When the first handle 305 is rotated, the drive tube 304 is driven to rotate synchronously. Since the drive tube 304 is threadedly connected to the L-shaped frame 300, it drives the rotating ring 303 to rotate and move vertically downward. Since the rotating ring 303 rotates inside the sleeve 302 and the L-shaped plate 301 is attached to the side of the end of the connecting plate 203, the rotation and vertical downward movement of the rotating ring 303 drives the L-shaped plate 301 to move vertically downward relative to the connecting plate 203. The movement involves moving the T-shaped plate 202 vertically downwards, adjusting the position of the L-shaped plate 301, and fixing its relative position. The T-shaped plate 202 is placed on the upper surface of the aluminum composite panel, and then the L-shaped plate 301 is driven to move vertically downwards, so that the L-shaped plate 301 enters the pre-grooved groove and its bottom end contacts the bottom surface of the pre-grooved groove. Then, the side of the L-shaped plate 301 is made to fit against the inner side of the pre-grooved groove, so that the subsequent extrusion plate 502 can slide out and extrude the relative inner side of the pre-grooved groove. The relative position of the L-shaped plate 301 is adjusted according to the required groove depth and width so that the L-shaped plate 301 is fixed in different grooves as a whole.

[0026] like Figure 5 , Figure 6 and Figure 7 As shown, optionally, the limiting mechanism includes a drive rod 400, a rotating head 402, a piston plate 403, a groove 404, and a second handle 405. The L-shaped plate 301 has an L-shaped cavity that communicates with the outside. The piston plate 403 is slidably connected to the inner side of the vertical section of the L-shaped cavity. The groove 404 is opened in the middle of the upper end face of the piston plate 403. The drive rod 400 passes through the rotating ring 303 and the inner side of the drive tube 304, and is threadedly connected to the middle of the upper end of the L-shaped plate 301. The rotating head 402 is fixed on the bottom end of the drive rod 400 and is rotatably connected to the inner surface of the groove 404. The second handle 405 is fixed on the outer side of the upper end of the drive rod 400. The piston plate 403 is vertically raised and lowered to drive the extrusion plate 502 to slide outward or be retracted inward.

[0027] In this embodiment, the drive rod 400 is rotated by the second handle 405. Since the drive rod 400 is threadedly connected to the middle of the upper end of the L-shaped plate 301, the drive rod 400 drives the rotating head 402 to rotate relative to the L-shaped plate 301 and move vertically downward. Since the rotating head 402 rotates in the groove 404 and the piston plate 403 slides on the inner side of the vertical section of the L-shaped cavity, when the drive rod 400 rotates and moves vertically downward, it drives the piston plate 403 to move vertically downward synchronously within the vertical section of the L-shaped cavity. When the second handle 405 rotates in the opposite direction, it drives the drive rod 400 to rotate and move vertically upward, thereby driving the rotating head 402 to rotate and move vertically upward synchronously, thus driving the piston plate 403 to move vertically upward within the vertical section of the L-shaped cavity, thereby driving the extrusion plate 502 to slide outward or retract inward.

[0028] like Figure 5-8 As shown, optionally, the L-shaped cavity is divided into a first chamber 500 and a second chamber 501 by a piston plate 403. The first chamber 500 is filled with hydraulic oil. A pressing plate 502 is horizontally slidably connected to the inner wall of the first chamber 500. A plurality of evenly distributed springs 504 are fastened between the inner end face of the pressing plate 502 and the inner side wall of the first chamber 500.

[0029] In this embodiment, when the piston plate 403 moves vertically downward in the second chamber 501, it squeezes the hydraulic oil. The hydraulic oil, when squeezed, pushes the extrusion plate 502 to slide horizontally outward relative to the first chamber 500. At this time, the spring 504 is stretched. When the extrusion plate 502 slides out, it presses against the inner side of the pre-grooved groove, so that the L-shaped plate 301 is fixed in the pre-grooved groove. The horizontal width of the L-shaped plate 301 is extended by the horizontal outward sliding of the extrusion plate 502, so that the L-shaped plate 301 can be fixed in grooves of different widths by adjustment. When the piston plate 403 moves vertically upward in the second chamber 501, the hydraulic oil no longer pushes the extrusion plate 502 to move outward. At this time, under the pull of the spring 504 to restore its deformation, the extrusion plate 502 slides inward to reset and is stored in the first chamber 500. At this time, the L-shaped plate 301 can be removed from the groove.

[0030] like Figure 8 As shown, optionally, an anti-slip pad 503 is attached to the outer end face of the extrusion plate 502.

[0031] In this embodiment, when the extrusion plate 502 slides outward, it drives the anti-slip pad 503 to slide outward simultaneously and press against the inner side of the pre-grooved surface. The deformation of the anti-slip pad 503 increases the friction between the extrusion plate 502 and the inner side of the pre-grooved surface, thereby improving the stability of the extrusion plate 502 and the L-shaped plate 301 within the pre-grooved surface. Furthermore, the overall fixation of the L-shaped plate 301 ensures the T-shaped plate 202 remains fixed relative to the aluminum composite panel, allowing the hand saw 100 to move stably along the length of the T-shaped plate 202 for grooving. The anti-slip pad 503 is made of rubber material with a certain degree of surface roughness.

[0032] like Figure 5 As shown, optionally, circular holes 505 are symmetrically opened on both sides of the upper end face of the L-shaped plate 301, and the circular holes 505 are connected to the second chamber 501.

[0033] In this embodiment, when the piston plate 403 moves vertically downward, the volume of the second chamber 501 increases, generating negative pressure. External air enters the second chamber 501 through the round hole 505 to ensure that the piston plate 403 moves downward stably. When the piston plate 403 moves vertically upward, the volume of the second chamber 501 decreases, compressing the air in the second chamber 501 to be discharged outward through the round hole 505, thus ensuring that the piston plate 403 moves upward stably.

[0034] like Figure 1 As shown, optionally, the outer surface of the L-shaped plate 301 is on the same surface as the mounting surface of the cutting wheel of the hand saw 100.

[0035] In this embodiment, when the outer contact surface of the L-shaped plate 301 and the mounting surface of the cutting wheel of the hand-held saw 100 are on the same surface, the L-shaped plate 301 can be aligned with the cutting groove when the cutting wheel of the hand-held saw 100 is replaced.

[0036] like Figure 1 As shown, optionally, multiple T-shaped plates 202 can be spliced ​​together end to end. One end of the T-shaped plate 202 is fixed with a stud, and the other end is provided with a matching threaded hole.

[0037] In this embodiment, by rotating the stud into the threaded hole, two adjacent T-shaped plates 202 can be spliced ​​together, thereby extending the length of the T-shaped plate 202 to facilitate grooving of aluminum composite panels of different lengths. Depending on the situation, splicing can also be omitted, and a single T-shaped plate 202 can be repeatedly used to groove longer aluminum composite panels.

[0038] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
