Description

Technical Field

[0001] The utility model belongs to the technical field of robot bending equipment, and particularly relates to a double-machine bending equipment for sheet metal. Background Technique

[0002] In a sheet metal production line, when bending large-sized sheet metal products, such as the maximum unfolded size: 5980*1965 and the weight of 120 kg, manual production completely fails to meet the requirements. Due to the large size and heavy weight of the products, 2 robots are required to synchronously and jointly complete the bending operation. Because the sheet metal size is large, the robots must move along the bending direction of the sheet metal product during bending to prevent the product from deforming to meet the processing accuracy requirements. Therefore, it is necessary to develop a double-machine bending equipment that can meet the processing accuracy requirements to achieve bending automation. Content of the Utility Model

[0003] The purpose of the utility model is to provide a double-machine bending equipment for sheet metal aiming at the above problems. Two robots are used to synchronously bend the products on a bending machine tool, realizing automatic bending processing and ensuring the processing accuracy and processing quality requirements.

Detailed implementation mode

[0015] The present utility model will be further described below in conjunction with specific examples and the accompanying drawings.

[0016] As Figures 1-3 shown, a double-machine bending device for sheet metal includes a bending machine tool 1. A horizontal robot track 2 is arranged in front of the front of the bending machine tool 1. A first bending robot 3 and a second bending robot 4 are arranged on the robot track 2 along the moving direction of the track. The shape and structure of the first bending robot 3 are the same as those of the second bending robot 4. A horizontal slide 41 is provided at the lowermost part of the second bending robot 4. A base 42 is provided on the horizontal slide 41. The base 42 is connected to the lower arm through an X-axis rotating shaft 43. The lower arm is connected to the middle arm through a first Y-axis rotating shaft 44. The middle arm is connected to the upper arm through a second Y-axis rotating shaft 45. A Z-axis rotating shaft 47 is provided in the middle of the upper arm. The other end of the upper arm is connected to a palm connecting seat 48 through a third Y-axis rotating shaft 46. The rotation amplitudes of the X-axis rotating shaft 43, the first Y-axis rotating shaft 44, the second Y-axis rotating shaft 45, the third Y-axis rotating shaft 46, and the Z-axis rotating shaft 47 are respectively controlled by air cylinders. The palm connecting seat 48 bends the workpiece 8 through the connected bending palm 5. The connecting end of the palm connecting seat 48 and the bending palm 5 is disc-shaped and is provided with 12 protruding columns distributed in a ring, and is connected to the clamping holes of the bending palm 5 through the protruding columns. A slide track 21 matching the horizontal slide 41 is provided above the robot track 2. Two parallel guide chain tracks 22 are provided below the robot track 2. A rack 23 is fixedly provided on the inner side wall of the robot track 2. A guide chain 412 and a slide driving motor 411 are installed on the horizontal slide 41. The slide driving motor 411 drives the gear to rotate and engage the rack 23 to drive the horizontal slide 41 to move horizontally. When the horizontal slide 41 moves horizontally, the guide chain 412 is embedded in the guide chain track 22 to keep the horizontal slide 41 moving in a straight line. The first bending robot 3 and the second bending robot 4 respectively occupy one guide chain track 22. The first bending robot 3 and the second bending robot 4 are controlled by the control cabinet 6 to synchronously push the bending palm 5 to bend the workpiece 8 clamped by the bending machine tool 1.

[0017] A protective enclosure 7 for protection is provided around the bending machine tool 1 and the robot track 2.

[0018] The stroke of the robot track 2 is greater than the working surface width of the bending machine tool 1, which is convenient for one bending robot to avoid to one side and vacate the operating space when a single bending robot is needed for operation.

[0019] For the dual-machine bending equipment for sheet metal designed by the present utility model, during use, according to the size of the workpiece 8 to be processed on the bending machine tool 1, the position of the bending palm 5 is adjusted, and then the positions of the first bending robot 3 and the second bending robot 4 on the robot track 2 are adjusted respectively, so that the palm connecting seats 48 on the upper parts of the first bending robot 3 and the second bending robot 4 are respectively aligned with the two bending palms 5. For example, when adjusting the position of the second bending robot 4 on the robot track 2, the gear is driven to rotate by the slide plate drive motor 411 to engage the rack 23 to drive the horizontal slide plate 41 to move horizontally. When the horizontal slide plate 41 moves horizontally, the guide chain 412 is embedded in the guide chain track 22 to keep the horizontal slide plate 41 moving in a straight line. By setting the precision of the rack 23, the translation precision of the bending robot can be controlled. Then, the rotation amplitudes of the X-axis rotating shafts, the first Y-axis rotating shafts, the second Y-axis rotating shafts, the third Y-axis rotating shafts, and the Z-axis rotating shafts of the first bending robot 3 and the second bending robot 4 are synchronously controlled by the control cabinet 6. The first bending robot 3 and the second bending robot 4 push the bending palm 5 to bend the workpiece 8 clamped by the bending machine tool 1, and during the bending process, the first bending robot 3 and the second bending robot 4 move together with the workpiece 8 to prevent local deformation of the workpiece 8 and ensure the bending processing quality. When a single bending robot is needed for work, for example, the second bending robot 4 is driven by the slide plate drive motor 411 to drive the gear to rotate and engage the rack 23 to drive the horizontal slide plate 41 to move horizontally to the rightmost side, and the first bending robot 3 is adjusted to a suitable position on the robot track 2 for individual operation.
