[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0022] The present embodiment provides a bending machine, which is mainly used to solve the problem that before using the current bending machine, it is generally necessary to align the bottom of the upper die with the notch of the lower die, that is, the knife setting operation. At present, when setting the knife, the user needs to align it visually, which is inefficient and has low accuracy. The following technical solutions are provided. Figures 1-4 Give detailed instructions:

[0023] An energy-saving electric bending machine comprises: a mounting frame 1 with an upper mold 2 on one side, and a lower mold 3 is arranged below the upper mold 2. When in use, the user needs to first install the lower mold 3 on the surface of the mounting frame 1 through a first limiting unit 5, and then install two infrared transmitters 6 and two infrared receivers 7 on both sides of the upper mold 2 and the lower mold 3 through a second limiting unit 9. In subsequent use, the user controls the lifting and lowering of the upper mold 2 through a driving unit 4. In this process, if the infrared rays emitted by the two infrared transmitters 6 can always be received by the infrared receiver 7 (the two infrared transmitters 6 and the two infrared receivers The receiver 7 is electrically connected to the controller 8 fixedly mounted on the surface of the mounting frame 1), then the controller 8 will display that the tool setting is successful, otherwise the user needs to adjust the position of the lower mold 3 (a buzzer can also be installed inside the controller 8 to remind the user of the success or failure of the tool setting). The main components of the driving unit 4 are: a driving groove 41 provided on the surface of the mounting frame 1. When in use, the user controls the hydraulic rod 43 fixedly mounted on the inner wall of the driving groove 41 through the controller 8 to extend and retract, which can drive the driving plate 42 slidably plugged into the inner wall of the driving groove 41 to slide, and further drive the driving plate 42 mounted on the driving plate 4 through the first mounting unit 44. 2. The upper mold 2 at one end is raised and lowered, wherein the main components of the first limiting unit 5 are: two guide grooves 51 are both opened on the surface of the mounting frame 1, and two guide plates 52 are slidably inserted in the inner walls of the two guide grooves 51. When in use, the user places the lower mold 3 on the surface of the mounting frame 1, and then rotates a plurality of driving threaded rods 53 respectively threadedly inserted in the surfaces of the plurality of guide plates 52, which can drive a plurality of pressing plates 54 respectively rotatably sleeved on the surfaces of the plurality of driving threaded rods 53 to move, so that the plurality of pressing plates 54 are all in contact with the surface of the lower mold 3, thereby achieving the clamping and limiting of the lower mold 3 on the surface of the mounting frame 1. The main components of the second limiting unit 9 are: several mounting protrusions 91 respectively arranged on the surface of the upper mold 2 and the lower mold 3. When in use, the user slides and inserts the infrared transmitter 6 into the surface of two of the mounting protrusions 91, inserts the infrared receiver 7 into the inner wall of the other two mounting protrusions 91, and finally threads the internal threaded tube 93 onto the surface of the external threaded tube 92 at one end of the two infrared transmitters 6, so as to realize the installation of the two infrared transmitters 6 and the two infrared receivers 7 (the installation position of the two infrared transmitters 6 is opposite to the cutting edge of the upper mold 2, and the installation position of the two infrared receivers 7 is opposite to the notch of the lower mold 3).

[0024] By setting an upper mold 2 on one side of the mounting frame 1, when in use, the user installs a lower mold 3 on the surface of the mounting frame 1 through the first limiting unit 5, and installs two infrared transmitters 6 and two infrared receivers 7 on the surfaces of the upper mold 2 and the lower mold 3 respectively through the second limiting unit 9. Finally, the upper mold 2 is pressed down by the driving unit 4. During the pressing process, the infrared rays emitted by the two infrared transmitters 6 are always irradiated on the two infrared receivers 7. If the infrared receivers 7 can always receive the infrared rays, then the tool alignment is accurate (make sure that both ends of the upper mold 2 are aligned with both ends of the lower mold 3). This method makes tool alignment faster and reduces the number of times the user repeatedly controls the extension and retraction of the hydraulic rod 43 during the tool alignment process, thereby achieving the purpose of energy saving.

[0025] By providing two guide grooves 51 on the surface of the mounting frame 1, when in use, the user slides a plurality of guide plates 52 into the inner walls of the two guide grooves 51, and rotates a plurality of driving threaded rods 53 respectively, thereby driving a plurality of guide plates 52 that are respectively rotatably sleeved on one end of the plurality of driving threaded rods 53 to move, so that the surfaces of the plurality of guide plates 52 respectively contact the two sides of the lower mold 3, thereby clamping and fixing the lower mold 3.

[0026] like Figure 3 As shown, in some embodiments, the main components of the first mounting unit 44 are: a first limiting protrusion 441 set on the surface of the driving plate 42. When in use, the user needs to slide a plurality of disassembly sleeves 442 on the surface of the first limiting protrusion 441, and then threadably insert two mounting bolts 443 into the surfaces of the plurality of disassembly sleeves 442, so that the surfaces of the plurality of mounting bolts 443 are threadably inserted into the surface of the first protrusion, and then the upper mold 2 is mounted on the inner walls of the driving plate 42 and the plurality of disassembly sleeves 442 through the second mounting unit 444. To complete the operation, the main components of the second installation unit 444 are: several second limiting protrusions 4441 respectively arranged on the surface of the driving plate 42 and the surfaces of several disassembly sleeves 442. After the installation of the several disassembly sleeves 442 is completed, the user can slide the inner wall of the I-shaped protrusion 4442 arranged on the top of the upper mold 2 onto the surfaces of the several second limiting protrusions 4441, and then rotate the several installation bolts 443 to drive the surfaces of the several disassembly sleeves 442 to contact the surface of the I-shaped protrusion 4442, thereby achieving a stable limitation on the upper mold 2.

[0027] The workflow of this utility model:

[0028] First, the user needs to install the plurality of disassembly and assembly sleeves 442 on the surface of the first limiting protrusion 441 through the plurality of mounting bolts 443, and then slide the inner wall of the I-shaped protrusion 4442 onto the surface of the plurality of second limiting protrusions 4441. Then, the user places the lower mold 3 on the surface of the mounting frame 1 and rotates the plurality of driving threaded rods 53 respectively to drive the plurality of pressing plates 54 to fit the surface of the lower mold 3, thereby limiting the position of the lower mold 3 on the surface of the mounting frame 1.

[0029] Secondly, the user needs to control the extension and retraction of the hydraulic rod 43 through the controller 8, driving the driving plate 42 to slide on the inner wall of the driving groove 41 to achieve control of the spatial height of the upper mold 2. During this process, if the infrared rays emitted by the two infrared transmitters 6 can always be received by the two infrared receivers 7, it means that the tool alignment is completed. Otherwise, the position of the lower mold 3 needs to be adjusted.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
