Description

Technical Field

[0001] This application relates to the field of shearing machine technology, and in particular to an integrated bending and shearing device for a bending machine. Background Technology

[0002] A shearing machine is a mechanical device that cuts metal sheets, profiles, and other materials using the relative motion of blades. It is widely used in machinery manufacturing, automotive parts production, and hardware processing. In bending processes, shearing machines are usually used in conjunction with bending equipment to cut bent workpieces to preset dimensions. It is one of the key pieces of equipment in the metal forming process, and its performance directly affects the cutting accuracy, processing efficiency, and production safety.

[0003] Traditional bending machine shearing devices mostly use a single power drive, and bending and shearing functions are often set up independently, requiring a dedicated independent shearing device. This increases the overall manufacturing cost and floor space of the equipment, and also results in a long processing distance from bending to shearing. Due to the single power system, the equipment cannot flexibly achieve rapid process switching between forward and reverse bending and shearing, making the operation process cumbersome. At the same time, the long bending and shearing distance can easily cause the blade to deviate during the shearing process, leading to shearing failure, reducing production efficiency, and posing a great safety hazard. To address these issues, we propose an integrated bending and shearing device for bending machines. Utility Model Content

[0004] This application provides an integrated bending and shearing device for a bending machine, which can precisely control the bending angle and shearing position according to the specific requirements of the processed graphic. It effectively solves the problems of cumbersome process switching and insufficient processing accuracy caused by the single power source of traditional equipment, and improves the processing adaptability of complex-shaped workpieces.

[0005] This application provides a bending and shearing integrated device for a bending machine, including a base. A first servo motor is fixedly mounted on the upper surface of the base. A coupling is fixedly mounted on the output end of the first servo motor. A transmission screw is fixedly mounted on the bottom end of the coupling. A screw fixing seat is threadedly connected to the outer surface of the transmission screw. A guide rail fixing block is fixedly mounted on one side of the screw fixing seat. An upper and lower slider is fixedly mounted on one side of the guide rail fixing block. A reduction gear fixing seat is fixedly mounted on one side of the upper and lower sliders. A reducer is fixedly mounted on the upper surface of the reduction gear fixing seat. A second servo motor is fixedly mounted on the input end of the reducer. An outer mold fixing block is fixedly mounted on the bottom end of the reduction gear fixing seat. An outer mold assembly is fixedly mounted on the bottom end of the outer mold fixing block.

[0006] Furthermore, an inner mold fixing block is fixedly installed on one side of the deceleration fixing seat, and an inner mold component is fixedly installed on the inner wall of the inner mold fixing block.

[0007] Furthermore, an outer mold auxiliary sleeve is installed at the bottom of the outer mold assembly, and inner and outer mold auxiliary bottom sleeves are fixedly installed on one side of the base.

[0008] Furthermore, a pressure block is fixedly installed at the bottom end of the lead screw fixing seat, and a pressure wheel is fixedly installed at the bottom end of the pressure block.

[0009] Furthermore, a cutting tool is placed on the upper surface of the base, and the bottom end of the pressure wheel is in contact with the upper surface of the cutting tool.

[0010] Furthermore, an air duct is fixedly installed on the outer surface of the base, one end of the air duct is located on one side of the outer mold assembly, a track is fixedly installed on the upper surface of the base, and multiple fixing holes are opened on the upper surface of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The technical solution provided in this application has at least the following technical effects or advantages:

[0013] The first servo motor drives the transmission screw and guide rail assembly to achieve precise up-and-down reciprocating motion, while the second servo motor drives the outer mold fixing block to complete reciprocating rotation through a reducer. The independent control and cooperation of the dual servo systems can easily realize multiple process switching of forward and reverse bending and shearing. It can also precisely adjust the bending angle and shearing position according to the specific requirements of the processed graphic, effectively solving the problems of cumbersome process switching and insufficient processing accuracy caused by the single power source of traditional equipment. It improves the processing adaptability of complex-shaped workpieces. Compared with the shearing device of traditional bending machines, it saves the independent shearing device, saves manufacturing costs, shortens the distance from bending to shearing, and improves production efficiency. It also solves the problem that during shearing, due to the certain distance between bending and shearing, the blade may deviate from the shearing device, making it impossible for the scissors to cut normally, requiring the operator to hold it by hand, which poses a safety hazard. This shearing device is safer. Attached Figure Description

A first servo motor 2 is fixedly mounted on the upper surface of the base 1. A coupling 8 is fixedly mounted on the output end of the first servo motor 2. A transmission screw 9 is fixedly mounted on the bottom end of the coupling 8. A screw fixing seat 10 is threadedly connected to the outer surface of the transmission screw 9. A guide rail fixing block 5 is fixedly mounted on one side of the screw fixing seat 10. An upper and lower slider 4 is fixedly mounted on one side of the guide rail fixing block 5. A reduction fixing seat 19 is fixedly mounted on one side of the upper and lower slider 4. The upper surface of the reduction fixing seat 19 is fixed with... A speed reducer 18 is installed, and a second servo motor 3 is fixedly installed at the input end of the speed reducer 18. An outer mold fixing block 20 is fixedly installed at the bottom end of the speed reducer fixing seat 19, and an outer mold assembly 21 is fixedly installed at the bottom end of the outer mold fixing block 20. The first servo motor 2 drives the transmission screw 9 to rotate through the coupling 8, which can convert the power into the up and down movement of the screw fixing seat 10, and drive the speed reducer fixing seat 19 to rise and fall synchronously through the guide rail fixing block 5 and the upper and lower sliders 4. The second servo motor 3 adjusts the speed and torque through the speed reducer 18 to drive the outer mold fixing block 20 and the outer mold assembly 21 to rotate.

[0022] Example 2:

[0023] An inner mold fixing block 16 is fixedly installed on one side of the deceleration fixing seat 19. An inner mold component 14 is fixedly installed on the inner wall of the inner mold fixing block 16. An outer mold auxiliary sleeve 22 is installed at the bottom of the outer mold assembly 21. An inner and outer mold auxiliary bottom sleeve 13 is fixedly installed on one side of the base 1. A pressure block 7 is fixedly installed at the bottom of the screw fixing seat 10. A pressure wheel 11 is fixedly installed at the bottom of the pressure block 7. The inner mold fixing block 16 fixes the inner mold component 14, enabling it to precisely cooperate with the outer mold assembly 21 to achieve bending and shaping of the cutting material 15. The outer mold auxiliary sleeve 22 enhances the strength of the outer mold assembly 21 and optimizes the contact effect. The inner and outer mold auxiliary bottom sleeve 13 supports the cutting material 15 from the bottom. At the same time, the screw fixing seat 10 drives the pressure wheel 11 to press the cutting material 15 through the pressure block 7 to prevent displacement during processing and ensure the accuracy of bending and shearing.

[0024] A cutting tool 15 is placed on the upper surface of the base 1. The bottom end of the pressure wheel 11 is in contact with the upper surface of the cutting tool 15. An air duct 6 is fixedly installed on the outer surface of the base 1. One end of the air duct 6 is located on one side of the outer mold assembly 21. A rail 12 is fixedly installed on the upper surface of the base 1. Multiple fixing holes 17 are opened on the upper surface of the base 1. The cutting tool 15 is placed on the base 1 and can be used as a processing object to accept bending and shearing operations of the outer mold assembly 21, inner mold part 14 and other execution components. The air duct 6 is fixed to the outer surface of the base 1, and one end is aligned with the outer mold assembly 21. By connecting the air pressure, waste material and slag are blown away during each shearing to avoid the accumulation of impurities affecting the processing quality and the stability of equipment operation.

[0025] The working principle of this application is as follows: First, the first servo motor 2 drives the coupling 8 to rotate, which enables the guide rail assembly of the transmission screw 9 to move up and down reciprocally. Then, the second servo motor 3 drives the reducer 18 and the outer mold fixing block 20 to move back and forth, which can realize forward bending, directional bending, forward shearing, and directional shearing. When the blade passes through the inner and outer mold openings, the first servo motor 2 descends to a certain position, and the second servo motor 3 bends according to the shape of the graphic. When the bending action is completed, the first servo motor 2 descends to a certain position, and the second servo motor 3 rotates at a certain angle to cut the material in one go. After the material is pre-cut, the material is bent. After the bending is completed, the first servo motor 2 descends to perform a second bottom cut. In addition, the air duct 6 is connected to air pressure, and waste material and waste residue generated during each shearing are removed.
