[0002] Electro-hydraulic servo CNC bending machine is a CNC bending equipment that uses electro-hydraulic servo control technology. Its core technology consists of a feedback control system composed of an electrical signal processing device and a hydraulic power mechanism, which integrates the advantages of electrical and hydraulic technologies. Among them, the stop finger of the electro-hydraulic servo CNC bending machine is a key component used in the operation of the bending machine. It plays a role in positioning and supporting the material to improve processing accuracy and efficiency.

[0003] Existing electro-hydraulic servo CNC bending machines require operators to manually adjust the position of the stop fingers when bending sheet metal parts to meet the bending positioning requirements of sheet metal parts of different lengths. However, manual adjustment poses safety hazards and is prone to accidents, and also results in low processing accuracy of sheet metal parts. Utility Model Content

[0004] The purpose of this invention is to provide a stop finger drive device for an electro-hydraulic servo CNC bending machine, which eliminates the need for manual adjustment of the stop finger position by operators, reduces safety hazards and avoids accidents, improves the processing accuracy of sheet metal parts, and solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The hydraulic cylinder drives a crossbeam to move back and forth on the base. A mounting seat is provided on the crossbeam, and a stop finger is provided on the mounting seat. The stop finger moves laterally on the crossbeam and is positioned on the mounting seat by a rod.

[0007] Preferably, the piston rod of the hydraulic cylinder is connected to a crossbeam, and a slide is provided at the bottom of the crossbeam. The slide is movably connected to a guide rod, and the guide rod is mounted on a base.

[0008] Preferably, the crossbeam is provided with guide rails and a lead screw, the guide rails are distributed on both sides of the lead screw, the lead screw is driven to rotate by a motor, and the motor is mounted on the crossbeam.

[0009] Preferably, there are two lead screws with opposite thread directions, connected by a coupling, and one of the lead screws is connected to the output shaft of the motor.

[0010] Preferably, the bottom of the mounting base is provided with a slider, which is movably connected to the guide rail, and the bottom of the mounting base is also provided with a traction block, which is movably connected to the lead screw.

[0011] Preferably, the insertion rod is disposed on the connecting plate, the connecting plate is connected to the fixed seat by a spring and a telescopic guide post, the fixed seat is mounted on the mounting base, and the connecting plate is provided with a pull rod, one end of the pull rod passing through the fixed seat and connected to an operating handle.

[0013] Preferably, the stop finger is provided with a through groove for inserting the rod, and the through grooves are evenly distributed.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The motor-driven lead screw of this invention rotates, causing the traction block, mounting base, and slider to move laterally under the guidance of the guide rail. The lateral movement of the mounting base allows the stop finger to also move laterally. At the same time, the hydraulic cylinder drives the crossbeam and slide to move back and forth under the guidance of the guide rod. The back and forth movement of the crossbeam allows the mounting base and stop finger set on the crossbeam to also move back and forth, thereby driving the stop finger to move to the appropriate position.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the issue that existing electro-hydraulic servo CNC bending machines require manual adjustment of the stop finger position during sheet metal bending, which poses safety hazards, increases the risk of accidents, and results in low machining accuracy, please refer to... Figures 1-7 This embodiment provides the following technical solution:

[0026] The finger-stop driving device of the electro-hydraulic servo CNC bending machine includes a base 1, on which a hydraulic cylinder 2 is installed. The hydraulic cylinder 2 drives the crossbeam 3 to move back and forth on the base 1.

[0027] In this embodiment, the piston rod of the hydraulic cylinder 2 is connected to a crossbeam 3, and a slide block 31 is provided at the bottom of the crossbeam 3. The slide block 31 is movably connected to the guide rod 11, and the guide rod 11 is mounted on the base 1.

[0028] A mounting base 4 is provided on the crossbeam 3, and a stop finger 5 is provided on the mounting base 4. The stop finger 5 moves laterally on the crossbeam 3.

[0029] In this embodiment, a guide rail 32 and a lead screw 33 are provided on the crossbeam 3. The guide rail 32 is distributed on both sides of the lead screw 33. The lead screw 33 is driven to rotate by a motor 34, which is mounted on the crossbeam 3.

[0030] In this embodiment, there are two lead screws 33 with opposite thread directions. The two lead screws 33 are connected by a coupling, and one of the lead screws 33 is connected to the output shaft of the motor 34.

[0031] Specifically, when the motor 34 drives the two lead screws 33 to rotate, the adjacent stop fingers 5 can move laterally towards or away from each other to meet the bending and positioning requirements of sheet metal parts of different lengths.

[0032] In this embodiment, a slider 41 is provided at the bottom of the mounting base 4, and the slider 41 is movably connected to the guide rail 32. A traction block 42 is also provided at the bottom of the mounting base 4, and the traction block 42 is movably connected to the lead screw 33.

[0033] Working principle: The motor 34 is started, which drives the lead screw 33 to rotate, causing the traction block 42, mounting seat 4, and slider 41 to move laterally under the guidance of the guide rail 32. The lateral movement of the mounting seat 4 causes the stop finger 5 to move laterally as well. At the same time, the hydraulic cylinder 2 is started, which drives the crossbeam 3 and slide 31 to move back and forth under the guidance of the guide rod 11. The back and forth movement of the crossbeam 3 causes the mounting seat 4 and stop finger 5 set on the crossbeam 3 to move back and forth as well, thereby driving the stop finger 5 to move to the appropriate position. The position of the stop finger 5 does not need to be manually adjusted by the operator, which can reduce safety hazards and avoid the occurrence of safety accidents. To a certain extent, it can improve the processing accuracy of sheet metal parts.

[0034] The stop finger 5 is positioned on the mounting base 4 via the insert rod 6.

[0035] In this embodiment, the insertion rod 6 is disposed on the connecting plate 61. The connecting plate 61 is connected to the fixed seat 64 by the spring 62 and the telescopic guide post 63. The fixed seat 64 is mounted on the mounting base 4. The connecting plate 61 is provided with a pull rod 65. One end of the pull rod 65 passes through the fixed seat 64 and is connected to the operating handle 651.

[0036] In this embodiment, the mounting base 4 is provided with a guide groove 43 for the horizontal movement of the stop finger 5. The stop finger 5 is positioned in the guide groove 43 provided on the mounting base 4 by the insertion rod 6. The stop finger 5 is provided with a through groove 51 for the insertion rod 6 to be inserted. The through grooves 51 are evenly distributed.

[0037] Working principle: The operating handle 651 drives the pull rod 65 to move, causing the connecting plate 61 and the insertion rod 6 to move synchronously. The spring 62 and the telescopic guide post 63 are compressed by the connecting plate 61 until the insertion rod 6 is no longer inserted into the stop finger 5. At this time, the stop finger 5 can be removed from the mounting base 4 for easy replacement and maintenance. The stop finger 5 can also be moved in the guide groove 43 set on the mounting base 4 for fine adjustment. After fine adjustment, the stop finger 5 is positioned in the guide groove 43 set on the mounting base 4 by the insertion rod 6, which is convenient to use.
