The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] See also Figures 1 to 3A new bending machine provided by an embodiment of the present utility model includes a frame 10 and a bending plate 20 arranged on the upper side of the frame 10, and also includes two groups of bending components 30 arranged on the frame 10, the bending components 30 include two motors 31, two synchronous belts 32 connected to the two motors 31 respectively, a screw synchronous wheel 33 connected to the two synchronous belts 32 at the same time, and a screw 34 connected to the screw synchronous wheel 33, the lower end of the screw 34 is connected to the bending plate 20, the outer side of the screw 34 is provided with a screw nut 35, the outer side of the screw nut 35 is provided with a bearing 36, the outer side of the bearing 36 is provided with a bearing seat 37, and the screw synchronous wheel 33 is provided at the upper end of the bearing seat 36.

[0022] The novel bending machine mentioned above achieves the purpose of reducing the power of a single motor by jointly driving a lead screw 34 through two or more motors 31, thereby reducing the cost of the bending machine.

[0023] It should be noted that for motors of the same power, the price of multiple small motors is cheaper than the price of one motor with the same total power.

[0024] It should also be noted that in other embodiments of the present invention, at least one bending assembly 30 can be provided, and at least two motors 31 can be provided, for example, 3, 4, or 5. Accordingly, corresponding synchronous belts 32 are provided so that each motor is connected to the screw synchronous wheel 33, so that multiple motors 31 can drive the screw to rotate at the same time.

[0025] Specifically, in the present application, the motor 31 serves as a power source, providing driving force for the entire bending operation. The selection of the motor 31 can be adapted according to the parameters such as torque and speed required for the actual bending, ensuring that sufficient and stable power can be output so that the bending action can proceed smoothly. The synchronous belt 32 plays an important role in transmitting the power of the motor 31 in the present application. It can accurately transmit the rotational power generated by the motor 31 to the subsequent transmission components (screw synchronous wheel 33). At the same time, it has the advantages of high transmission efficiency, accurate transmission ratio, and the ability to ensure the synchronous operation of multiple transmission parts, thereby avoiding bending deviations caused by inconsistent power transmission. The screw 34 is connected to the screw synchronous wheel 33, and its lower end is connected to the bending plate 20. When the screw synchronous wheel 33 receives power and rotates, the screw 34 will rotate accordingly. Through the spiral transmission principle between the screw 34 and the screw nut 35, the rotational motion is converted into linear motion, thereby driving the bending plate 20 to move up and down, realizing the bending operation of the workpiece to be bent. Screw nut 35 is mounted on the outside of screw 34 and cooperates with screw 34. When screw 34 rotates, screw nut 35 moves linearly along the axial direction of screw 34. It is one of the key components for converting the rotational motion of screw 34 into linear motion. The precision of its cooperation with screw 34 has a significant impact on the accuracy of the bending operation. Bearing 36 is mounted on the outside of screw nut 35. Its main function is to reduce the friction of screw nut 35 during rotation and linear motion, ensuring that screw nut 35 can move smoothly, while also helping to improve the stability and service life of the entire transmission system. Bearing 36 is mounted on the outside of bearing seat 37, which supports bearing 36 and provides a stable mounting base for the entire transmission structure, ensuring that bearing 36 operates in the proper position and state. Screw synchronizing wheel 33 is located at the upper end of bearing seat 37, making the structural layout of the entire bending assembly 30 more compact and reasonable, and the coordinated operation between the various components more stable and efficient.

[0026] In one embodiment of the present invention, the bending plate 20 is connected to the screw 34 via a screw connector 38 , and the lower end of the screw connector 38 is threadedly connected to the bending plate 20 .

[0027] In one embodiment of the present invention, a screw tensioning sleeve 39 is provided on the inner side of the screw synchronous wheel 33, and the screw 34 is connected to the screw synchronous wheel 33 through the screw tensioning sleeve 39. This makes the connection between the screw 34 and the screw synchronous wheel 33 tighter and more stable.

[0028] In one embodiment of the present invention, the motor 31 is connected to the frame 10 via a motor mounting plate 40 .

[0029] In one embodiment of the present invention, a guide block 50 is provided on one side of the bearing seat 38. Two guide wheels 60 are spaced apart on the bending plate 20 at positions corresponding to the guide block 50 to guide the bending assembly 30 and improve machining accuracy. During operation, the guide block 50 is clamped between the two guide wheels 60 and moves up and down, preventing the bending assembly 30 from moving horizontally in the front-to-back direction and thus providing guidance.

[0030] In one embodiment of the present invention, a plurality of anti-slip teeth (not shown) are vertically provided on the side of the screw synchronous wheel 33 to increase the friction between the synchronous belt 32 and the screw synchronous wheel 33, thereby improving the power transmission efficiency. Specifically, a gear mechanism can be provided on the inner side of the synchronous belt 32, and cooperate with the screw synchronous wheel 33 to prevent slipping.

[0031] In one embodiment of the present invention, the frame 10 is provided with a bending clamp 70 in the direction of the descending of the bending plate 20 to fix the product to be clamped. Specifically, the bending clamp 70 can be set according to the shape of the product and can be a common machine tool clamp such as a hydraulic clamp.

[0032] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
