Description

Technical Field

[0001] The utility model relates to a production line for panel and water tank processing, belonging to the technical field of panel water tank production equipment. Background Art

[0002] Some panels, sinks and other workpieces need to be folded twice on their four sides, so that the four sides are finally formed into a C-shaped bend. The processing of panels, sinks and other workpieces involves multiple processes, such as unwinding and leveling of coils, cutting and blanking of plates, and before folding, it is necessary to make holes, cut corners, and trim the plates to form workpiece blanks, and fold the workpiece blanks. At present, in the folding process of panels, sinks and other workpieces, the degree of automation is low, and many processes are relatively independent of the folding process, resulting in low production efficiency and high production costs. Moreover, in the existing folding processing technology of workpieces such as panels and sinks, the processing steps such as edge trimming, corner trimming, and hole making before the workpiece folding need to be processed by punching equipment, cutting equipment, corner trimming equipment, etc., which requires many processing equipment and processing steps, low processing efficiency, and high production cost; In addition, in the prior art, when folding workpieces such as panels and sinks, most of them use one folding machine to fold the four sides of the workpiece blank one by one, such as the Chinese invention patent with publication number CN109175044B, or use two folding machines arranged opposite to each other to fold the four sides of the workpiece blank one by one, such as the Chinese invention patent with publication number CN 109047398 A's Chinese invention patent application first uses a folding mechanism on one side to bend one of the sides of a workpiece, then adjusts the position of the workpiece to the workpiece positioning position of the folding mechanism on the other side, uses the folding mechanism on the other side to bend the side opposite to the processed side, and then rotates the workpiece 90 degrees and then bends the other two opposite sides of the workpiece one by one. This processing method has low processing efficiency and the workpiece needs to be positioned and adjusted in direction multiple times. Utility Model Content

A movable clamp mechanism is arranged on the folding machine discharge channel. The feeding device comprises a feeding bracket, a large beam, a small beam, and a workpiece grasping mechanism. Feeding brackets are arranged at the front and rear ends of the folding machine discharge channel respectively. The two ends of the large beam are movably arranged on two feeding brackets respectively. A lifting mechanism that can move laterally is arranged on the large beam. The small beam is connected to the lower end of the lifting mechanism, and the workpiece grasping mechanism is connected to the lower part of the small beam. ;

[0005] When the utility model is working, the metal coil is unrolled and leveled by the unrolling and leveling device, and the leveled plate is fed into the disc conveying mechanism of the laser cutting device. The laser cutting machine of the laser cutting device can perform laser hole making, laser angle cutting, and laser cutting on the plate located on the disc conveying mechanism. The laser cutting machine itself can move laterally along the movable crossbeam, and the laser cutting machine can move longitudinally with the movable crossbeam, so as to realize the laser processing of the metal plate. The plate processed by the laser cutting device is conveyed to the roller forming machine through the feed channel of the roller forming machine, and the plate is clamped and conveyed by the upper folding roller and the lower folding roller of the roller forming unit. During the conveying process, the two sides of the plate are respectively bent under the action of the folding mold parts of the upper folding roller and the lower folding roller. Since the shape of the folding mold part between the upper folding roller and the lower folding roller is gradually changed, the two sides of the plate are gradually bent into a C shape during the conveying process. The workpieces that have been folded into a C-shape on both sides are transported to the workbench inside the folding machine, and the workpieces are centered by the centering mechanism of the folding machine. The clamping mechanism of the folding machine drives the clamping beam to move downward through the clamping cylinder, and clamps the workpiece through the pressure head. The flip beam of the bending mechanism on the feeding side of the folding machine is flipped under the action of the flip cylinder to bend the side of the workpiece on the feeding side. The flip beam of the bending mechanism on the discharging side of the folding machine is flipped under the action of the flip cylinder to bend the side of the workpiece on the discharging side. The movable pressing plates set at the four corners of the pressure head of the folding machine are used to clamp the four corners of the workpiece, making it easier for the bending mechanism to bend the workpiece. Before the workpiece enters the folding machine, its left and right sides have been folded into a C-shape, which will interfere with the pressure head. The edges of the four corners of the pressure head cannot fully contact the C-shaped inner parts of the two sides of the workpiece, and the workpiece cannot be effectively pressed. By setting movable pressing plates at the four corners, the movable pressing plates are in a downward position when the pressure head does not contact the workpiece. When the pressure head moves toward the workpiece, the movable pressing plates can be inserted into the C-shaped edge of the workpiece. After the pressure head contacts the workpiece, the movable pressing plate rotates to a horizontal position to press the edge of the workpiece. The feeding of the workpiece during the folding process on the feed side and the discharge side of the folding machine is completed by the roller forming machine and the clamp mechanism set on the folding machine discharge channel. After the folding machine completes the folding of the workpiece, the clamp mechanism set on the folding machine discharge channel drags the processed workpiece to the folding machine discharge channel, and then the stacking device grabs the workpiece on the folding machine discharge channel to the subsequent trolley for stacking. The workpiece grabbing mechanism of the stacking device can grab the workpiece, and the workpiece grabbing mechanism itself can be raised and lowered on the large beam and can move along the large beam. At the same time, the workpiece grabbing mechanism can also move along the unloading bracket with the large beam.

[0006] Furthermore, a coding device is provided at the discharge end of the roll forming machine, through which identification codes can be sprayed on the workpieces.

[0007] Furthermore, the uncoiler and leveling device includes two uncoilers, which are arranged at intervals along the feeding direction, and an auxiliary support is provided on the side of each uncoiler, and the auxiliary support includes a support, a swing arm, a rotating frame, and a swing arm cylinder. One end of the swing arm is rotatably connected to the support, and the other end of the swing arm is provided with a V-shaped bracket. The rotating frame includes a first rotating frame and a second rotating frame, one end of the first rotating frame is hinged to one end of the second rotating frame, the other end of the first rotating frame is hinged to the support, and the other end of the second rotating frame is hinged to the swing arm, one end of the swing arm cylinder is hinged to the support, and the other end of the swing arm cylinder is hinged to the second rotating frame.

[0008] Furthermore, in order to facilitate the processing of workpieces of different sizes, the pressure head of the folding machine is composed of a plurality of detachable pressure plates. By replacing the pressure plates, pressure heads of different sizes can be formed, which is convenient for adapting to the processing of workpieces of different sizes.

[0009] Furthermore, in order to facilitate transmission and processing of workpieces of different sizes, the upper hemming roller of the left forming roller group and the upper hemming roller of the right forming roller group in the roll forming machine are arranged on the same upper roller shaft, and a spacer is arranged between the two upper hemming rollers on the same upper roller shaft; the lower hemming roller of the left forming roller group and the lower hemming roller of the right forming roller group are arranged on the same lower roller shaft, and a spacer is arranged between the two lower hemming rollers on the same lower roller shaft. By arranging a spacer between the two hemming rollers on the same roller shaft, the distance between the two hemming rollers can be changed by replacing spacers of different specifications, thereby adapting to the hemming of workpieces of different sizes.

[0010] The beneficial effects of the utility model are as follows: the utility model can realize the automated processing of panels and sinks, which can greatly improve production efficiency and reduce production costs. The utility model can use a laser cutting machine to perform laser hole making, laser angle cutting and laser cutting processing on metal plates by setting a laser cutting device. The processing is simple and efficient. It can replace the punching equipment, cutting equipment, shearing equipment and the like in the existing processing technology. The processing steps are few and the production cost can be reduced. The utility model adopts a roller forming machine to first bend and form the two sides of the workpiece, and then folds the front and rear ends of the workpiece by a folding machine, which can effectively improve the processing efficiency and ensure reliable processing quality.

[0067] When the utility model is working, the metal coil is unrolled and leveled by the unwinding machine and the leveling machine, and the leveled plate is sent to the processing station on the disc conveying mechanism 3-1 of the laser cutting device 3, and the plate on the disc conveying mechanism 3-1 is laser-punched, laser-cut and laser-cut by the laser cutting machine 3-2.
