Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiment one:

[0022] As shown in Figures 1-5 , an automatic positioning and bending angle controllable bending machine, comprising a workbench 1, both sides of the workbench 1 are fixedly connected with a shell 2, a longitudinal drive assembly 3 is penetratingly and slidingly connected at the inner side wall of the shell 2, a transverse drive assembly 4 is penetratingly arranged at the rear end of the shell 2, the front end of the transverse drive assembly 4 is movably connected to the right end of the longitudinal drive assembly 3, an upper die assembly 5 is fixedly connected to the rear side of the longitudinal drive assembly 3, a lower die 6 is arranged at the top side of the workbench 1, the bottom end of the upper die assembly 5 is above the lower die 6, the lower die 6 is sequentially provided with pressing grooves of different angles, the inner angles sequentially increase from back to front, a positioning sensor 7 is arranged at the bottom side of the lower die 6, the bottom side of the positioning sensor 7 is inside the workbench 1, a controller 8 is arranged at the front side of the workbench 1, and a base 9 is fixedly installed at the bottom of the workbench 1.

[0023] As shown in Figure 1 , Figure 2 ,Figure 4 and Figure 5 As shown, the longitudinal drive assembly 3 includes a rotary motor 31, a rotating rod 32, a gear 33, and a rack 34. The side wall of the rotary motor 31 is located on the side wall of the outer shell 2. The side end of the rotating rod 32 passes through and slides in the side walls of both outer shells 2. The rear side of the rack 34 is fixedly connected to the front right end of the upper mold assembly 5. The front end of the transverse drive assembly 4 is movably connected to the right end of the rotating rod 32. The output end of the rotary motor 31 is fixedly connected to the right end of the rotating rod 32. The outer side of the rotating rod 32 passes through the shaft of the gear 33. The gear 33 and the front teeth of the rack 34 mesh with each other. When the rotary motor 31 is started, its output end drives the rotating rod 32 to rotate. The gear 33 on the rotating rod 32 rotates synchronously with the rotating rod 32. Under the drive of the longitudinal drive assembly 3, the upper mold assembly 5 moves longitudinally downward along the inner side wall of the outer shell 2.

[0024] like Figure 3 and Figure 5 As shown, the transverse drive assembly 4 includes a support platform 41 and a linear motor 42. The support platform 41 and the linear motor 42 are located at the rear right end of the worktable 1. The support platform 41 is located at the rear end of the housing 2. The output end of the linear motor 42 passes through the interior of the housing 2 and is movably connected to the right end of the longitudinal drive assembly 3. The bottom side of the linear motor 42 is fixedly connected to the top of the support platform 41. When the linear motor 42 is started, its output end pushes or pulls the right end of the rotating rod 32, thereby driving the entire longitudinal drive assembly 3 to move back and forth in the transverse direction. Example 2:

[0025] like Figure 4 As shown, the upper mold assembly 5 includes a pressure mold 51 and a conical hot press plate 52. The top end of the conical hot press plate 52 is located inside the bottom end of the pressure mold 51. The two sides of the pressure mold 51 are slidably connected to the inner side wall of the outer shell 2. The bottom end of the conical hot press plate 52 faces the top of the lower mold 6. The top end of the conical hot press plate 52 is located inside the bottom end of the pressure mold 51. During the bending operation, the conical hot press plate 52 can not only cooperate with the lower mold 6 to bend and shape the workpiece.

[0026] Working principle: such as Figures 1-5 As shown, when a bending operation is required, the rotating motor 31 is started, and its output end drives the rotating rod 32 to rotate. The gear 33 on the rotating rod 32 rotates synchronously with the rotating rod 32. Since the gear 33 and the rack 34 mesh with each other, the rotation of the gear 33 will drive the rack 34 to slide longitudinally along the inner sidewall of the outer casing 2.

[0027] The rear side of the rack 34 is fixedly connected to the front right end of the upper mold assembly 5. Therefore, the upper mold assembly 5 will move longitudinally downward along the inner wall of the outer shell 2 under the drive of the longitudinal drive assembly 3.

[0028] The support table 41 provides a stable support base for the linear motor 42, when it is necessary to adjust the position of the upper die assembly 5 in the transverse direction, the linear motor 42 is started, and its output end pushes or pulls the right end of the rotating rod 32, thereby driving the longitudinal driving assembly 3 to move forward and backward in the transverse direction as a whole, thereby realizing the position adjustment of the upper die assembly 5 in the transverse direction;

[0029] The lower die 6 is sequentially provided with different angle pressing grooves, and the inner angles increase from back to front. During the bending process, the controller 8 controls the coordinated movement of the longitudinal driving assembly 3 and the transverse driving assembly 4, so that the upper die assembly 5 can accurately align the pressing groove with the required angle on the lower die 6, thereby realizing the accurate control of the bending angle of the workpiece;

[0030] The positioning sensor 7 is located at the bottom side of the lower die 6 and its bottom side is inside the workbench 1, which can detect the position and state information of the workpiece in real time, and feed back these information to the controller 8, and the controller 8 further adjusts the action of the longitudinal driving assembly 3 and the transverse driving assembly 4 according to the feedback information, to ensure that the bottom of the upper die assembly 5 can align the pressing groove with different angles at the top side of the lower die 6, and ensure the accuracy and stability of the bending process;

[0031] The top end of the conical hot pressing plate 52 is arranged inside the bottom end of the pressing die 51, and in the bending operation, the conical hot pressing plate 52 can cooperate with the lower die 6 to bend and shape the workpiece.
