DETAILED DESCRIPTION

[0029] The specific implementation of the present invention is briefly described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Figure 1-Figure 3 The preferred embodiments of the present invention are shown, and their structures are analyzed in detail from different angles.

[0031] like Figure 1 , 2 An automatic heating bending device shown includes a frame 1, a control cabinet 2, a feeding mechanism, a bending component and a heater 4.

[0032] Among them, the frame 1 is used to install the entire device, and the control cabinet 2 is used to control the power on and off of the heater 4 and control the feeding mechanism and the cylinder in the bending component to move the mold to complete the stamping and bending of the workpiece 17.

[0033] The feeding mechanism is arranged at the feeding end of the frame 1, including a feeding cylinder 5 fixedly connected to the frame 1 and a manipulator 6 fixedly connected to the output end of the feeding cylinder 5. The manipulator 6 clamps the workpiece 17 and moves forward under the drive of the feeding cylinder 5, and places the workpiece 17 on the bottom mold 7 after being heated by the heater 4.

[0034] The bending assembly is arranged on the frame 1 and is used for punching and bending the workpiece 17 , and comprises a lifting mechanism, a first punching mechanism, an auxiliary punching mechanism, a second punching mechanism and a cutting mechanism.

[0035] The lifting mechanism is vertically fixedly connected to the frame 1, and the top of the lifting mechanism is fixedly connected to the bottom mold 7 for placing the workpiece 17. Specifically, the lifting mechanism includes an adjusting screw 12, an adjusting flange 11, a pressure spring 13 and a bottom mold slider 25 sleeved on the adjusting screw 12. The adjusting screw 12 is fixedly connected to the bottom surface of the frame 1, and the bottom mold slider 25 is slidably connected to the guide rail provided on the frame 1, and its end away from the pressure spring is fixedly connected to the bottom surface of the bottom mold. The adjusting flange is moved up and down to drive the bottom mold slider 25 to move up and down, so that the height of the bottom mold 7 can be adjusted to be suitable for the workpiece production required by workpieces 17 of different sizes. The pressure spring 13 is arranged between the bottom mold slider 25 and the adjusting flange 11, which can play a certain elastic buffering role when the stamping die 18 moves down and cooperates with the bottom mold 7 to stamp the workpiece 17, thereby improving the service life of the equipment.

[0036] The lifting mechanism also includes a limit block 15 which is detachably fixedly connected to the frame 1 and can be adjusted up and down according to the required height of the bottom mold 7. The limit block 15 cooperates with the steps on both sides of the bottom mold 7 to limit the height of the bottom mold 7 to be moved up and reset under the elastic action of the pressure spring 13 after the stamping die 18 completes a stamping reset, thereby ensuring that the height of the bottom mold 7 is consistent when the workpiece 17 is bent multiple times. Specifically, the limit block 15 is a rectangular parallelepiped with the same width as the width of the steps on the bottom mold 7, and is connected to the frame 1 by a snap connection, a pin connection, or a screw connection.

[0037] The first stamping mechanism is arranged vertically above the jacking mechanism, including a stamping cylinder 19 fixedly connected to the frame 1 and a stamping die 18 arranged at the output end of the stamping cylinder 19. The stamping die 18 moves downward under the drive of the stamping cylinder 19 and cooperates with the bottom die 7 to stamp the workpiece 17.

[0038] like Figure 3 As shown, an auxiliary stamping mechanism is also provided on the back of the stamping mechanism, and the auxiliary stamping mechanism includes a connecting rod mechanism and a telescopic mold core 8. One end of the connecting rod mechanism is fixedly connected to the back of the stamping die 18, and the other end is fixedly connected to the telescopic mold core 8. Under the up and down movement of the stamping die 18, the connecting rod mechanism drives the telescopic mold core 8 to move forward and backward.

[0039] Specifically, the connecting rod mechanism includes a first connecting rod 20, a second connecting rod 23, a third connecting rod 24, a fixed bracket 21 vertically fixedly connected to the frame 1, and a bearing 22 arranged at one end of the fixed bracket 21 away from the frame 1. One end of the first connecting rod 20 is vertically fixedly connected to the back of the stamping die 18, and the other end is hinged to the second connecting rod 23. One end of the second connecting rod 23 is hinged to the first connecting rod 20, and the other end is hinged to the third connecting rod 24. A slide groove 231 is formed on the second connecting rod 23 along its extension direction. The bearing 22 is arranged in the slide groove 231 and slides in the slide groove 231 when the second connecting rod 23 moves up and down with the stamping die 18. The end of the third connecting rod 24 away from the second connecting rod 23 is fixedly connected to the telescopic core 8.

[0040] A set of vertical guide rails are arranged on the frame 1 at the position corresponding to the telescopic mold core 8. A hollow slider that can slide up and down along the frame 1 is arranged in the guide rail. The telescopic mold core 8 is arranged in the hollow slider for horizontal sliding. When the punching die 18 moves up and resets, the second link 23 moves up driven by the first link 20 and gradually moves forward under the action of the bearing 22. The third link 24 drives the telescopic mold core 8 to move upward and forward under the action of the second link 23. At the same time, the third link 24 is driven to rotate under the action of the horizontal hollow slider to keep the telescopic mold core 8 horizontal, so that the telescopic mold core 8 automatically extends and presses the workpiece 17 when the punching die 18 moves up and resets. When the punching die 18 moves down to punch the workpiece 17, the telescopic mold core 8 moves in the opposite direction and contracts.

[0041] The second punching mechanism is horizontally arranged relative to the feeding mechanism, and includes a limit feeding cylinder 14 fixedly connected to the frame 1 and a movable die 16 fixedly connected to the output end of the limit feeding cylinder 14. The movable die 16 moves horizontally under the drive of the limit feeding cylinder 14, and cooperates with the extended telescopic die core 8 to bend the workpiece 17.

[0042] The cutting mechanism is arranged above the workpiece 17, and includes a cutting cylinder 10 fixedly connected to the frame 1 and a cutting die 9 arranged at the output end of the cutting cylinder 10. The cutting die 9 moves downward under the drive of the cutting cylinder 10 to cut the workpiece 17. Specifically, one end of the bottom die slider 25 connected to the bottom die 7 is also fixedly connected with a top block 3 that cooperates with the cutting die 9 to cut the workpiece 17, and the upper surface height of the top block 3 is the same as the upper surface height of the bottom die 7.

[0043] The heater 4 is disposed between the feeding mechanism and the bending assembly, and is electrically connected to the control cabinet 2 , and is used for electrically heating the workpiece 17 .

[0044] Furthermore, a movable slider is provided between the stamping die 18, the movable die 16 and the cutting die 9 and their corresponding cylinders. The movable slider is slidably connected to the guide rail provided on the frame 1, one end of which is fixedly connected to the die, and the other end of which is fixedly connected to the output end of the cylinder.

[0045] When the workpiece 17 is bent: first, the height of the lifting mechanism is adjusted to the required height by adjusting the flange 11, and the bottom mold 7 is installed on the top of the lifting mechanism; then, the heater 4 is started, and the workpiece 17 is clamped by the manipulator 6 and moved to the top of the heater 4 for heating under the drive of the feeding cylinder 5; then, the workpiece 17 after heating is transported to the top of the lifting mechanism under the clamping of the manipulator 6 and placed in the bottom mold 7, and then, the stamping cylinder 19 drives the stamping mold 18 to quickly press down and reset. During the resetting process of the stamping cylinder 19, the connecting rod mechanism is driven to drive the telescopic mold core 8 to move forward and press the workpiece 17; at the same time, the limit feed cylinder 14 is started to drive the movable mold 16 to cooperate with the telescopic mold core 8 to perform secondary stamping on the workpiece 17; finally, after the stamping is completed, the cutting mechanism is started, and the cutting mold 9 is driven by the cutting cylinder 10 to quickly punch down, and cooperate with the top block 3 below to cut off the workpiece 17, completing the processing of the workpiece 17 into the product.
