It is widely used in sheet bending processing in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles.

[0003] The bending machines currently on the market can only bend one workpiece at a time. After completing the bending operation, the staff will take the workpiece to be bent from the position where the workpiece is placed next to it and place it on top of the lower die. The existing bending machines require the staff to move to take the workpiece during the workpiece loading process, which is inconvenient and slow. Therefore, we propose a bending machine that is convenient for loading. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a bending machine with convenient loading, including a bending machine body 1, a lower die 2 and an upper die 4, the lower die 2 is installed on the surface of the bending machine body 1, and a connecting seat 3 is arranged above the bending machine body 1, and an upper die 4 is installed at the bottom of the connecting seat 3, a hydraulic cylinder 5 is installed on the top of the bending machine body 1, and the output end of the hydraulic cylinder 5 is connected to the connecting seat 3, and limiting components 6 are arranged on both sides of the bending machine body 1, and the limiting components 6 include a fixed plate 61, a movable groove 62, a guide groove 63, a movable sleeve 64, a movable frame 65, a guide block 66, a threaded rod 67 and a motor 68, and the fixed plate 61 is connected to both sides of the bending machine body 1.

[0024] A movable groove 62 is provided in the middle of the fixed plate 61, and guide grooves 63 are provided on both sides of the inner wall of the fixed plate 61 close to the movable groove 62; a movable sleeve 64 is docked inside the movable groove 62, and a movable frame 65 is connected to the top of the movable sleeve 64, and guide blocks 66 are connected on both sides of the movable sleeve 64; the guide block 66 is docked with the guide groove 63, and a threaded rod 67 passes through the middle of the movable sleeve 64; both ends of the threaded rod 67 are connected to the inner wall of the movable groove 62 through a bearing seat, a motor 68 is installed on the outer side of the fixed plate 61, and the output end of the motor 68 passes through the fixed plate 61 and is connected to the threaded rod 67, the threaded rod 67 and the movable sleeve 64 are threadedly connected, the cross-sectional size of the guide block 66 matches the cross-sectional size of the guide groove 63, and the guide block 66 and the guide groove 63 are slidably connected.

[0025] During specific implementation, the starting motor 68 drives the threaded rod 67 connected to the output end to rotate synchronously. Since the threaded rod 67 and the movable sleeve 64 are threadedly connected, the threaded rod 67 will cause the outer movable sleeve 64 to move outward along the inside of the movable groove 62 when it rotates. The movable sleeve 64 moving outward drives the movable frame 65 connected to the top to move outward synchronously. At this time, the guide blocks 66 connected on both sides of the movable sleeve 64 move stably along the inside of the guide groove 63 until the movable frame 65 is moved outward to the extreme position. At this time, the movable frame 65 is misaligned with the fixed plate 61, and the width between the movable frame 65 and the fixed plate 61 is the widest. The movable frame 65 and the fixed plate 61 arranged on both sides of the bending machine body 1 can neatly support the workpiece to be bent, and it can be directly taken when loading, which facilitates the rapid loading of the bending machine.

[0026] A control panel 7 is connected to the outside of the bending machine body 1, and movable seats 8 are arranged on both sides of the bending machine body 1 close to the lower die 2, and docking grooves 9 are opened inside the movable seats 8; a connecting frame 10 is arranged above the two movable seats 8, and a docking block 11 is connected to the bottom end of the connecting frame 10; the docking block 11 is connected to the docking groove 9, and a cleaning bristle 12 is arranged on the inner wall of the connecting frame 10, and the cleaning bristle 12 is in contact with the surface of the lower die 2, the cross-sectional size of the docking block 11 matches the cross-sectional size of the docking groove 9, and the docking blocks 11 are symmetrically distributed about the center line of the connecting frame 10.

[0027] During specific implementation, after the bending operation is completed, the upper mold 4 is separated from the lower mold 2, and the staff holds the connecting frame 10 and pushes the connecting frame 10 to the end close to the lower mold 2. The pushed connecting frame 10 moves stably along the docking groove 9 inside the movable seat 8 through the docking block 11 connected to the bottom. Since the cleaning bristles 12 connected to the inner wall of the connecting frame 10 are in contact with the surface of the lower mold 2, the connecting frame 10 will drive the cleaning bristles 12 connected to the inner wall to brush and clean the surface of the lower mold 2 when it is pushed. After cleaning, the connecting frame 10 can be pushed to the initial position again. The impurities adhered to the surface of the lower mold 2 can be cleaned in time by the back and forth moving connecting frame 10 and cleaning bristles 12 to prevent impurities from adhering to the workpiece and affecting the quality, thereby making the bending machine have a cleaning structure.

[0028] To sum up, when using the bending machine with convenient loading, first move the bending machine body 1 to the designated working position and turn on the power supply, then place the workpiece to be bent above the lower die 2, and then start the hydraulic cylinder 5 to drive the connecting seat 3 and the upper die 4 connected to the output end to move downward synchronously until the upper die 4 and the lower die 2 overlap and collide with each other. At this time, the hydraulic bending of the workpiece between the upper die 4 and the lower die 2 can be completed. After the bending is completed, the hydraulic cylinder 5 contracts and drives the upper die 4 to move upward to separate from the lower die 2, and the bent workpiece can be taken out.
