Description

Technical Field

[0001] This utility model relates to the field of servo pipe bending machine technology, and in particular to a servo pipe bending machine with a fixed structure. Background Technology

[0002] The servo pipe bending machine with a fixed structure is a high-precision and high-efficiency metal pipe processing equipment. It adopts a rigid frame and modular fixed fixtures to ensure stability, and achieves precise control through a multi-axis servo system (such as bending axis and feeding axis). With the help of replaceable molds and mandrel anti-wrinkle devices, it can complete bending at complex angles (such as 0-190°). It is suitable for automotive, aerospace and other fields, and features high repeatability (±0.1mm) and high degree of automation.

[0003] In the prior art, Chinese utility model patent CN213350517U discloses a servo clamping structure for a pipe bending machine, including a pipe bending arm. A connecting inner groove is formed inside the pipe bending arm. A clamping slider is slidably connected to the top of the pipe bending arm directly above the connecting inner groove. An adjusting slider is fixedly connected to the bottom of the clamping slider. A positioning base is fixedly connected to the bottom of the adjusting slider. A positioning inner hole is formed in the middle of the positioning base, and the positioning base is located within the connecting inner groove. A servo motor is installed at the bottom of the pipe bending arm, and a mounting side plate is installed on one side of the pipe bending arm. The servo motor and ball screw improve the stability of the structure. The rotation of the servo motor drives the ball screw to rotate, causing the clamping slider, which is sleeved outside the ball screw, to slide. This allows the clamping slider to slide between the pipe bending arm and the pipe bending arm, thereby fixing the connecting pipe between the pipe bending arm and the clamping slider. The operation is simple.

[0004] Problems with existing technology: The aforementioned servo clamping structure for pipe bending machines cannot stably clamp pipes of various diameters during the bending process and it is inconvenient to control the clamping force, which can easily cause deformation and damage to the pipes, affecting the yield rate of bent pipes.

[0005] Therefore, there is an urgent need for a servo-driven pipe bending machine with a fixed structure. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a servo pipe bending machine with a fixed structure.

[0007] The technical problem solved by this utility model is achieved through the following technical solution: a servo pipe bending machine with a fixed structure, including a base, a fixed cylinder installed at one end of the base, and a fixing mechanism disposed inside the fixed cylinder for clamping and fixing the connecting pipe, and a driving mechanism disposed on one side of the clamping mechanism for driving the fixing mechanism to operate. The fixing mechanism includes a fixing frame, which is fixed to the middle position of the fixed cylinder by bolts. Multiple push rods are slidably connected to both sides of the fixing frame. An arc-shaped plate is fixedly installed at one end of each push rod. Notches A are provided at both ends of the arc-shaped plate, and notches B are provided on the outer side of the arc-shaped plate. A pressure sensor is fixedly installed at the middle position of the arc-shaped plate.

[0008] As a further embodiment of this utility model: the driving mechanism includes a mounting base, which is uniformly welded to the outer wall of the fixed frame. A crossbeam is fixedly installed above the mounting base. A servo motor is fixedly installed at one end of the crossbeam. A bidirectional lead screw is fixedly installed at the rotating end of the servo motor. A driving block is driven to both ends of the bidirectional lead screw. An L-shaped support arm is fixedly installed at one end of the driving block. The L-shaped support arm is fixedly connected to the push rod.

[0009] As a further embodiment of this utility model: a lifting mechanism is provided above the base for driving the fixed cylinder to adjust its height. The lifting mechanism includes a connecting frame, which is fixed to the base by bolts. A square tube is provided above the connecting frame, and a hydraulic rod is fixedly installed in the middle of the square tube. A top rod is fixedly installed at the extended end of the hydraulic rod, and the top rod is fixedly connected to the fixed cylinder.

[0010] As a further improvement of this utility model, both the fixing mechanism and the driving mechanism are evenly arranged along the outer circumference of the fixing cylinder.

[0011] As a further improvement of this utility model, a rubber pad is provided on the inner wall of the arc-shaped plate.

[0012] As a further improvement of this utility model, a servo pipe bending device is fixedly installed at one end of the base.

[0013] As a further improvement of this utility model: a controller is fixedly installed on the outer wall of the fixed cylinder, and the controller is electrically connected to the servo motor and the pressure sensor.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. A servo motor drives a bidirectional lead screw to rotate, which in turn drives push rods to move closer or further apart. The push rods push the arc plates closer together, and notches A and B interlock. This allows the servo pipe bending machine with a fixed structure to stably clamp connecting pipes of various diameters during the bending process. At the same time, a pressure sensor controls the clamping force of the arc plates to prevent excessive clamping force and avoid deformation and damage to the connecting pipes, thus ensuring a high yield rate of bent connecting pipes.

[0016] 2. The hydraulic rod drives the lifting rod to rise and fall. The lifting rod is slidably connected to the square tube, and drives the fixed cylinder to adjust its height. This allows the servo pipe bending machine with a fixed structure to meet the bending operations at various heights. The servo pipe bending equipment automatically bends the connecting pipe, expanding the application range of the servo pipe bending machine with a fixed structure. Attached Figure Description

The fixing mechanism includes a fixing frame 101, which is bolted to the middle position of the fixed cylinder 200. The inner wall of the fixing frame 101 is hexagonal. Multiple push rods 201 are slidably connected to both sides of the fixing frame 101. One of the push rods 201... An arc-shaped plate 202 is fixed to the end by bolts. A push rod 201 pushes the arc-shaped plate 202 to move. A rubber pad 210 is attached to the inner wall of the arc-shaped plate 202 to protect the outer surface of the connecting pipe. Notches A203 are cut at both ends of the arc-shaped plate 202, and notches B204 are cut on the outer side of the arc-shaped plate 202. Notches A203 and B204 are interlocked.

The drive mechanism includes a mounting base 102, which is uniformly welded to the outer wall of the frame 101. A crossbeam 103 is bolted to the top of the mounting base 102.

The rotation of bidirectional lead screw 105 drives drive blocks 106 to move closer or further apart. One end of drive block 106 is fixed with an L-shaped support arm 107 by bolts. The L-shaped support arm 107 is fixedly connected to push rod 201. Bidirectional lead screw 105 drives push rod 201 to move closer or further apart.

The push rods 201 push the arc plates 202 closer together, and the notches A203 and B204 cooperate crosswise, so that the servo pipe bending machine with a fixed structure can stably clamp connecting pipes of various diameters during the bending process. At the same time, the pressure sensor 205 controls the clamping force of the arc plate 202 to prevent excessive clamping force and avoid deformation and damage to the connecting pipe, thus ensuring the yield rate of the bent connecting pipe.
