Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, and particularly relates to a single-servo pure-electric bending machine. Background Technique

[0002] A bending machine is a machine that can bend thin plates and is widely used in industries such as metal processing, household appliances, construction, electronics, and automobiles to achieve precise and efficient bending processing of metal sheets. By placing the metal material on the workbench and then using the pressure and bending mechanism of the machine to bend the material. Specifically, when the hydraulic pump sends hydraulic oil into the hydraulic cylinder, pressure is generated and transmitted to the upper die or the upper die through the control of the hydraulic valve, thereby generating the required bending force. During the bending process, the metal sheet remains stable under the fixation of the clamping plate and is bent through the pressure action of the upper die or the upper die.

[0003] For example, the Chinese authorized patent "A Bending Machine" with the publication number CN217858167U includes a machine frame, a workbench, a lifting plate, a clamping assembly, a positioning assembly, a fixing frame, a mold, a supporting assembly, and a driving device; one end of the machine frame is connected to the rear side of the workbench, and the other end of the machine frame is connected to the rear side of the lifting plate. The driving device is used to drive the lifting plate to move up and down. The lifting plate is provided with a plurality of clamping assemblies, and the plurality of clamping assemblies are evenly arranged along the length direction of the lifting plate. The clamping assembly is used to clamp the tool; two installation strips protrude from the top surface of the workbench, and a first installation groove is formed between the two installation strips. The first installation groove is provided with a mold, and the supporting assembly is installed on the front side of the workbench; the fixing frame is installed on the machine frame, the fixing frame is located at the rear side of the workbench, and the positioning assembly is movably installed on the fixing frame.

[0004] Although the above-mentioned prior art can realize the bending processing of metal plates, on the one hand, the installation structure of the upper die is relatively troublesome and cannot achieve precise positioning on the premise of ensuring portable installation. On the other hand, the material supporting mechanism needs to replace the mold to cooperate with the upper die to achieve forming at different angles, which is not only more troublesome to operate but also affects the processing efficiency of the metal plate. Therefore, it does not meet the existing requirements, and for this reason, we propose a single-servo pure-electric bending machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a single-servo pure-electric bending machine to solve the problem that the installation structures of the upper die and the material supporting mechanism of the bending machine are relatively troublesome as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A single-servo pure electric bending machine, comprising a base, and a workbench protruding forward is fixedly arranged above the base; further comprising: a material supporting mechanism, which is arranged on the upper end surface of the workbench, and the material supporting mechanism is composed of a fixing plate, an adjusting plate and an adjusting component. The fixing plate is fixed at the upper end of the material supporting mechanism. An adjusting shaft penetrating through both sides is fixedly arranged inside the adjusting plate, and the adjusting shaft is rotationally connected with the material supporting mechanism;

[0007] A driving mechanism, which is arranged above the material supporting mechanism, and the rear end of the driving mechanism is fixed to the base through a support column. A lifting seat is slidably installed inside the driving mechanism, and a guide rail mounting seat is fixedly arranged at the bottom of the lifting seat;

[0008] A mounting block, which is installed outside the guide rail mounting seat, and the mounting block is slidably matched with the guide rail mounting seat. Positioning blocks are arranged in the inner cavities at the front and rear ends of the guide rail mounting seat. Positioning grooves are arranged at the front and rear of the inner groove wall of the mounting block, and the positioning blocks are adapted to the positioning grooves.

[0009] Preferably, a servo motor is fixedly installed above one side of the driving mechanism. The output shaft of the servo motor is provided with a driving shaft extending into the driving mechanism. First bevel gears are fixedly arranged at both ends of the driving shaft. First screw rods are fixedly and rotatably installed on both sides of the inner cavity of the driving mechanism. A second bevel gear is fixedly arranged at the upper end of the first screw rod, and the second bevel gear is meshed with the first bevel gear.

[0010] Preferably, sliding blocks are fixedly arranged on both sides of the lifting seat. The first screw rod penetrates through the sliding blocks, and the first screw rod is in threaded cooperation with the sliding blocks.

[0011] Preferably, a first adjusting wheel is rotatably installed on one side of the front end of the material supporting mechanism. A worm is arranged at one end of the first adjusting wheel located inside the material supporting mechanism. A worm gear adapted to the worm is arranged above the worm, and the shaft at one end of the worm gear is fixed to the adjusting shaft.

[0012] Preferably, a second adjusting wheel is rotatably installed on one side of the guide rail mounting seat, and the shaft at one end of the second adjusting wheel extends into the guide rail mounting seat. A third bevel gear is fixedly arranged at one end of the second adjusting wheel located inside the guide rail mounting seat. Fourth bevel gears are meshed on both sides of the third bevel gear.

The second screw rod extends into the positioning block, and the second screw rod is in threaded connection with the positioning block.

[0013] Preferably, an upper die is fixedly installed at the bottom of the mounting block.

[0014] Preferably, an operation panel is installed on the side of the base.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, the material supporting mechanism is designed with an adjustable angle. By rotating the first adjusting rod, the worm is driven to rotate. The contact surface between the worm and the worm wheel forms a spiral friction transmission surface. The rotation of the worm drives the worm wheel to rotate, and then the adjusting shaft is driven to rotate by the worm wheel. Subsequently, the adjusting plate is driven to rotate through the adjusting shaft, realizing the angle adjustment between the fixing plate and the adjusting plate. At this time, the metal plate is positioned above the material supporting mechanism, and the bending operation of the metal plate is realized in cooperation with the upper die. This structure not only has a convenient and easy-to-operate adjustment method, overcomes the problem of the traditional need to replace the material supporting mechanism, improves the bending efficiency of the metal plate, but also utilizes the self-locking property of the worm and worm wheel to ensure the stability of the adjusting plate at the set angle and ensure the bending precision of the metal plate.

[0017] 2. The present utility model is provided with a convenient upper die disassembly and assembly structure. When installing the upper die, it only needs to be aligned with the guide rail mounting seat from the side, and the mounting block is moved to the designated position in a sliding form. Subsequently, by rotating the second adjusting wheel, the third bevel gear is driven to rotate. Under the meshing with the fourth bevel gear, the second screw rod is driven to rotate. The external thread of the second screw rod meshes with the internal thread hole of the positioning block. With the guiding effect of the inner groove of the guide rail mounting seat on the positioning block, the positioning holes on both sides are synchronously extended outward continuously until they enter the positioning grooves of the mounting block, forming the firmness of the mounting block at this position, providing a good premise for the upper die and the material supporting mechanism to cooperate to form the metal plate.

[0018] 3. The present utility model is provided with a single servo pure electric drive mechanism. By turning on the servo motor, its output shaft drives the drive shaft equipped with the first bevel gear to rotate. Under the meshing effect, the second bevel gear device is driven, and then the first screw rod is driven to rotate. Its external thread frictions with the internal thread hole of the sliding block, converting the rotational motion into a linear motion. Thus, the lifting seat is driven to move vertically by the sliding block to realize the operation of the upper die and the material supporting mechanism for mold closing and mold separation. This single servo pure electric drive mechanism realizes the direct correlation between the input power of the motor and the load power, significantly reducing the energy consumption under no-load or low-load conditions. At the same time, its high transmission efficiency is more energy-saving than hydraulic transmission, and the transmission system has a simple and efficient structure, and the overall maintenance cost is relatively low.

[0028] A mounting block 7, which is installed outside the guide rail mounting seat 6, and the mounting block 7 is slidably matched with the guide rail mounting seat 6. Positioning blocks 26 are arranged in the inner cavities at the front and rear ends of the guide rail mounting seat 6. Positioning grooves 25 are arranged at the front and rear of the inner groove wall of the mounting block 7, and the positioning blocks 26 are adapted to the positioning grooves 25. An upper die 8 is fixedly installed at the bottom of the mounting block 7.

[0029] The blank holding mechanism 3 is designed with adjustable angle, and the adjustment method is convenient and easy to operate, overcoming the problem of the traditional need to replace the blank holding mechanism, improving the bending efficiency of the metal plate. The portable upper die disassembly and assembly structure provides a good premise for the cooperation between the upper die 8 and the blank holding mechanism 3 to realize the forming of the metal plate. The single servo pure electric drive mechanism realizes the direct correlation between the motor input power and the load power, significantly reducing the energy consumption under no-load or low-load conditions. At the same time, its high transmission efficiency is more energy-saving than hydraulic transmission, and the transmission system structure is simple and efficient, with relatively low overall maintenance costs.

[0030] Please refer to Figure 3 , above one side of the drive mechanism 4, a servo motor 13 is fixedly installed. The output shaft of the servo motor 13 is equipped with a drive shaft 14 extending into the drive mechanism 4. Both ends of the drive shaft 14 are fixedly provided with first bevel gears 15.

[0031] When the servo motor 13 is turned on, its output shaft drives the drive shaft 14 equipped with the first bevel gear 15 to rotate. Under the meshing action, it drives the second bevel gear 18 device, thereby driving the first screw rod 16 to rotate. The external thread thereof rubs against the internal thread hole of the slide block 17, converting the rotational motion into a linear motion, thereby driving the lifting seat 5 to move vertically through the slide block 17 to realize the operation of the upper die 8 and the blank holding mechanism 3 for mold closing and separation.

The second screw rod 22 extends into the positioning block 26 and is threadedly connected to the positioning block 26;

[0035] When installing the upper die 8, it is only necessary to align it with the guide rail mounting seat 6 from the side, move the mounting block 7 to the designated position in a sliding manner, and then drive the third bevel gear 23 to rotate by rotating the second adjusting wheel 12. The second screw rod 22 is driven to rotate under the meshing with the fourth bevel gear 24. The external thread of the second screw rod 22 is meshed with the internal screw hole of the sliding block 17. With the guiding effect of the inner groove of the guide rail mounting seat 6 on the positioning block 26, the two sides of the positioning block 26 are synchronously and continuously extended outwards until they enter the positioning groove 25 of the mounting block 7, forming the firmness of the mounting block 7 at this position.
