[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0029] Reference Figures 1 to 6 As shown, an automatic feeding and bending device for special-shaped aluminum tubes is provided, including a machine tool 1, the machine tool 1 is provided with a loading mechanism 2, a feeding mechanism 3 is provided on one side of the loading mechanism 2, a pre-bending upper die 41 and a forming bending upper die 51 are provided above the feeding mechanism 3, a pre-bending lower die 42 and a forming bending lower die 52 are provided below the feeding mechanism 3, the pre-bending upper die 41 and the pre-bending lower die 42 are arranged close to the loading mechanism 2, and a feeding mechanism 6 is provided on the side of the feeding mechanism 3 away from the loading mechanism 2.

[0030] In this embodiment, the raw materials are placed on the loading mechanism 2, and then the equipment is started. The raw materials on the loading mechanism 2 are sent to the feeding mechanism 3, and then the feeding mechanism 3 sends the raw materials to the lower die of the pre-bending process and places them, and waits for the pre-bending upper die 41 to be pressed down, and then the pre-bent product is sent to the lower die of the forming bending process of the next process through the feeding mechanism 3 and placed, and waits for the forming bending upper die 51 to be pressed down, and finally the formed and bent product is sent to the unloading mechanism 6 for unloading through the feeding mechanism 3. Automatic feeding replaces manual feeding, which can solve the safety hazards of manual operation and solve the current problem of labor shortage in enterprises.

[0031] In one embodiment of the present invention, the loading mechanism 2 includes a material guide trough 21 and a grabbing assembly 22. The grabbing assembly 22 is movably arranged below the material guide trough 21. The raw materials will be placed in the material guide trough 21. The grabbing assembly 22 starts to grab the raw materials from the bottom so that the remaining raw materials will be automatically replenished downward due to the action of gravity. In order to facilitate the downward movement of the raw materials in the material guide trough 21, a pulley or a smooth inner lining plate is provided on the inner side of the material guide trough 21 to reduce the friction between the raw materials and the inner side of the material guide trough 21, thereby facilitating the downward movement of the raw materials and improving efficiency.

[0032] Furthermore, the grabbing assembly 22 includes a first cylinder 221 and a grabbing block 222. The first cylinder 221 is provided with a first telescopic rod, and the first telescopic rod is installed with a second cylinder 223. The second cylinder 223 is provided with two first sliders 225. The bottom of the grabbing block 222 is provided with a slide groove 224. The grabbing block 222 is movably connected to the first slider 225 to enable the grabbing block 222 to be opened and closed. When the first telescopic rod contracts toward the direction of the first cylinder 221, the grabbing blocks 222 on the second cylinder 223 will move away from each other and be in an open state, ready to clamp the raw materials. When the grabbing blocks 222 reach under the raw materials, they approach each other for clamping, and then the first telescopic rod moves away from the first cylinder 221 to pass the raw materials to the next process.

[0033] Preferably, a discharge frame bottom plate 211 is fixedly provided on the machine tool 1, and grooves 212 are provided on both sides of the discharge frame bottom plate 211. The guide trough 21 is slidably provided in the groove 212, and the position of the guide trough 21 on the discharge frame bottom plate 211 can be adjusted, so that the grabbing assembly 22 can grab the raw materials on the guide trough 21 more accurately. The bottom of the discharge frame bottom plate 211 is also connected to the upper and lower adjustment plates, and a straight plate is provided below the upper and lower adjustment plates. The straight plate is connected to the upper and lower adjustment plates through an adjustment column, and the straight plate is fixedly connected to the machine tool 1. Therefore, the guide trough 21 can move along the length direction of the groove 212, and can also be displaced in the vertical direction by adjusting the upper and lower adjustment plates, so that the grabbing assembly 22 can grab the raw materials on the guide trough 21 more accurately.

[0034] In one embodiment of the present invention, the feeding mechanism 3 includes a fixed plate 31 and a third cylinder 32. The top surface of the fixed plate 31 is sequentially provided with a first gripper 33, a second gripper 34 and a third gripper 35. The bottom surface of the fixed plate 31 is fixedly installed with a second slider 311. A lifting plate 36 is provided below the fixed plate 31. A slide rail 361 is provided on the lifting plate 36. The second slider 311 is slidably provided on the slide rail 361. The third cylinder 32 is provided with a second telescopic rod. One end of the second telescopic rod is connected to one end of the fixed plate 31 through a connecting plate 37. The first gripper 33, the second gripper 34 and the third gripper 35 are all spaced apart on the top surface of the fixed plate 31. The first gripper 33 is horizontally arranged, and the second gripper 34 and The third gripper 35 is set at an angle. Since the aluminum tube is a straight tube before pre-bending, the first gripper 33 is set horizontally to better grasp the raw material that has not been pre-bent. The raw material after pre-bending will be arc-shaped, so the second gripper 34 and the third gripper 35 are all set at an angle to facilitate grasping arc-shaped products. Several adjustment holes are provided on the fixed plate 31. The first gripper 33, the second gripper 34 and the third gripper 35 can be adjusted to their respective positions on the fixed plate 31. When the second telescopic rod on the third cylinder 32 moves, the fixed plate 31 is driven to move back and forth on the slide rail 361 of the lifting plate 36 through the connecting plate 37. The three grippers can make multiple product parts be grasped and displaced at the same time, thereby improving efficiency.

[0035] like Figure 4 As shown, the two fixing plates 31 are connected by a connecting plate, so that the two fixing plates 31 share a third cylinder 32. The connecting plate enables the two fixing plates 31 to move simultaneously, thereby reducing the setting of one cylinder and reducing equipment costs.

[0036] In one embodiment of the present invention, a fourth cylinder 362 is provided below the lifting plate 36, one end of the fourth cylinder 362 is fixedly mounted on the machine tool 1, and the other end of the fourth cylinder 362 is connected to the lifting plate 36 so that the lifting plate 36 can move up and down. A movable rod is provided between the lifting plate 36 and the machine tool 1 to connect the two. The fourth cylinder 362 can make the lifting plate 36 move up and down, and the lifting plate 36 drives the fixed plate 31, so that the first gripper 33, the second gripper 34 and the third gripper 35 can all be adjusted up and down to better grasp the product.

[0037] In one embodiment of the present invention, the unloading mechanism 6 includes a unloading guide plate 61, which is arranged at an angle. A plurality of surrounding plates 62 are provided on the outer periphery of the unloading guide plate 61 to prevent the formed and bent products from being shaken out when they are sent to the unloading guide plate 61. A unloading port 63 is provided at one end of the unloading guide plate 61 away from the feeding mechanism 3. The product slides from the inclined unloading guide plate 61 to the unloading port 63 due to gravity and is sent to the next process.

[0038] In one embodiment of the present invention, the pre-bending upper die 41 and the pre-bending lower die 42 are arc-shaped structures that cooperate with each other, and the forming bending upper die 51 and the forming bending lower die 52 are arc-shaped structures that cooperate with each other.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
