Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing equipment, in particular to a front feeding device of a suction cup type bending center. Background Art

[0002] A bending center is a device that bends metal sheets. Usually, the sheet metal is manually fed to a front feeding device, which then cooperates with the main machine to bend the sheet metal.

[0003] Existing front-end feeding devices in bending centers mostly use a pressure-arm feed mechanism. The C-arm, a sliding integral component, has a pressure mechanism below the front end of the C-arm and a downward pressure mechanism above the front end, which contains a pressure shaft and a rotating shaft. The downward pressure mechanism clamps the sheet material between the upper and lower pressure platens. The C-arm then slides as a whole, driving the sheet material to the workstation for bending. This complex overall structure is costly, and the C-arm, which is elevated above the platform conveyor surface, occupies a considerable height space, making it difficult to install a robotic loading and unloading mechanism above, and thus limiting the scalability of the production line.

[0066] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0067] like Figures 1-8 As shown, the present invention provides a front feeding device of a suction cup type bending center, including a first linear module 1, a second linear module 2, a third linear module 3, a movable seat 4, a rotating suction cup assembly 5, a front positioning stop finger 6, a side positioning stop finger 7 and a rear positioning stop finger 8. Figure 1 The X, Y, and Z directions shown in the figure are respectively the first direction, the second direction, and the third direction in the present invention.

[0068] The front feeding device of the suction cup bending center of this embodiment is used to feed the sample. Figure 1 and Figure 5 As shown, the device is often used in conjunction with the existing feeding table 10, which is composed of two flat table surfaces. The first linear module 1 is placed below the feeding table 10 and moves along the first direction ( Figure 1 The second linear module 2 is placed above the first linear module 1 and is arranged along the second direction ( Figure 1 The third linear module 3 extends along the second direction and is staggered with the second linear module 2. The movable seat 4 is installed on the first linear module 1, and the first linear module 1 can drive the movable seat 4 to move back and forth along the first direction; the rotating suction cup assembly 5 is slidably installed on the movable seat 4 for adsorbing and rotating the sample, and the rotating suction cup assembly 5 can move along the third direction ( Figure 1 The front positioning stop finger 6 is installed on the rotating suction cup assembly 5 and can abut against the front side of the template; there are two side positioning stop fingers 7, which are installed on the second linear module 2. The second linear module 2 can drive the two side positioning stop fingers 7 to move along the second direction and abut against the left and right sides of the template; the rear positioning stop finger 8 is slidably installed on the third linear module 3 and abuts against the rear side of the template.

[0069] In the initial state, the top surface of the rotating suction cup assembly 5 is at the same height plane as the feeding table 10. Before the sample is placed on the feeding table 10, the front positioning stop finger 6, the side positioning stop finger 7, and the rear positioning stop finger 8 need to be moved away to provide sufficient placement area to prevent the front positioning stop finger 6, the side positioning stop finger 7, and the rear positioning stop finger 8 from interfering with it when the sample is placed. Specifically, the first linear module 1 drives the movable seat 4 to move away from the second linear module 2, and the second linear module 2 drives the two side positioning stop fingers 7 to move away from each other synchronously, and respectively move to the two end areas of the second linear module 2. The rear positioning stop finger 8 moves on the third linear module 3 in the same way, and can be moved to one end or both ends of the third linear module 3. When the front positioning stop finger 6, the side positioning stop finger 7, and the rear positioning stop finger 8 move to a place larger than the sample, the sample is placed across the feeding table 10, and the degree direction of the sample is the same as the first direction.

[0070] After the sample is placed, the first linear module 1 drives the moving seat 4 to move toward the second linear module 2, and the second linear module 2 drives the two side positioning fingers 7 to move relatively close to the middle, and the rear positioning finger 8 moves to the middle area of ​​the third linear module 3, so that the front and rear sides of the sample on the feeding table 10 correspond to the front positioning finger 6 and the rear positioning finger 8, and the left and right sides of the sample respectively abut against the two side positioning fingers 7 to ensure that the front, rear, left and right positioning of the sample are correct.

[0071] After the front, back, left and right positioning of the sample are completed, the first linear module 1 is started, driving the moving seat 4 to move a short distance away from the second linear module 2, and the front positioning stop finger 6 is separated from the front end of the sample. At the same time, the rotary suction cup assembly 5 moves downward along the third direction. Since the front positioning stop finger 6 is also installed on the rotary suction cup assembly 5, when the rotary suction cup assembly 5 moves downward along the third direction, the front positioning stop finger 6 moves downward synchronously with the rotary suction cup assembly 5 until the rotary suction cup assembly 5 is lower than the bottom surface of the sample as a whole. Then the first linear module 1 is started again to drive the moving seat 4 and the rotary suction cup assembly 5 to move as a whole to the bottom of the sample center. Afterwards, the rotary suction cup assembly 5 moves in the third direction, and the rotary suction cup assembly 5 starts vacuuming and adsorbs the bottom surface of the center of the template. After the adsorption is stable, the first linear module 1 starts again, driving the movable seat 4 and the rotary suction cup assembly 5 and the template adsorbed thereon to move together in a direction away from the second linear module 2, and the template is sent to the subsequent bending equipment (not shown in the figure) for bending. The rotary suction cup assembly 5 can adsorb the template and drive the template to rotate, and can realize the template's 90°, 180° and 270° side-changing bending rotation, thereby achieving one-time positioning and completing all the bending processes of a template, which is conducive to improving the feeding and bending efficiency. After the bending is completed, the rotary suction cup assembly 5 can vacuum adsorb the formed template, and under the driving action of the first linear module 1, further send the formed template to the rear material collection area.

[0072] The front feeding device of the suction cup type bending center can realize the front, back, left and right positioning of the sample after unloading, and the rotating suction cup assembly can also absorb the sample through vacuum, and can also drive the sample to rotate to realize subsequent side bending at different angles. Compared with the existing flexible bending center with a C-type feeding mechanism, the front feeding device of the suction cup type bending center does not occupy the space above the feeding table, and there are no other structural parts above the feeding table, which is conducive to the subsequent clamping of other components such as robots. It has strong expandability and the structure of the whole device is simpler, and the cost is low.
