Description

Technical Field

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

[0002] A pipe bending machine is a forming device specifically designed to bend metal or non-metal pipes into specific shapes. It uses mechanical force to push, press, and bend the pipe, changing its axial direction without damaging it, thus forming bends of various angles and curvatures. Pipe bending machines typically consist of a power system, a control system, a mold system, and a clamping system. They can precisely control the bending angle, bending radius, and bending speed to meet different processing requirements. They are widely used in the automotive, aerospace, shipbuilding, chemical, and power industries to manufacture various pipes, fittings, and structural components.

[0003] Traditional pipe bending machines typically rely on manual operation for pipe clamping, making it difficult to automate the process. Operators must manually adjust the position of the clamping blocks, which is not only time-consuming and labor-intensive but also inefficient. Furthermore, during the bending process, traditional pipe bending machines often fail to securely fix the pipe, which can easily lead to pipe displacement, affecting bending accuracy and even causing deformation or damage. Additionally, the lack of additional fixing points and support makes it difficult to guarantee the stability of the bending process.

[0004] Therefore, those skilled in the art have provided a pipe bending machine push-bending structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pipe bending machine push-bending structure. A first servo motor drives a bidirectional threaded rod to automatically clamp the clamping block, while a guide rod ensures its linear motion. A second servo motor, via a connecting rod and a rotating disk, drives the push block to move along a semi-circular groove trajectory to adapt to different bending requirements. A fixing rod and a limiting groove provide additional fixing points to ensure stability during the push-bending process. The automated design reduces manual operation and improves production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pipe bending machine push-bending structure includes a mounting plate, two clamping blocks, and a rotating disk. A mounting base is fixedly connected to the middle of the upper surface of the mounting plate. Two first mounting slots are formed at the rear end of the upper surface of the mounting base. A protective shell is fixedly connected to the rear end of one side of the outer wall of the mounting base. A first servo motor is installed inside the protective shell. A bidirectional threaded rod is installed inside the first mounting slot at the rear end. The output end of the first servo motor at the rear end passes through the mounting base to the interior of the first mounting slot and is fixedly connected to the middle of one side of the bidirectional threaded rod. A guide rod is fixedly connected to the inner wall of the first mounting slot at the front end. Sliding blocks are sleeved on both sides of the outer walls of the guide rod and the bidirectional threaded rod. The upper ends of the sliding blocks on the same side are fixedly connected to the lower surface of the clamping blocks. A support block is fixedly connected to the middle of the upper surface of the rear end of the mounting base.

[0008] Through the above technical solution, the clamping block can be automatically clamped by moving relative to the pipe in the horizontal direction through the first servo motor driving the bidirectional threaded rod. This controls the clamping position and the starting point of bending of the pipe. The guide rod ensures the linear movement of the sliding block and the clamping block, preventing the clamping block from shifting or rotating during the movement. The automated design reduces manual operation and improves production efficiency.

[0009] Furthermore, a fixing rod is provided at the middle of the front end of the clamping block, and a limiting groove is opened at the middle of the front and rear ends of the fixing rod. A second servo motor is fixedly connected to the inner bottom surface of the middle of the front end of the mounting plate. A second mounting groove is opened at the middle of the lower surface of the front end of the mounting base. A connecting rod is provided at the middle of the lower end of the second mounting groove. The output end of the second servo motor passes through the mounting plate to the interior of the second mounting groove and is fixedly connected to the middle of the lower end of the connecting rod. A semi-circular groove is opened at the middle of the upper surface of the front end of the mounting base. The lower end of the semi-circular groove is connected to the interior of the second mounting groove. The upper end of the connecting rod is fixedly connected to the middle of the lower end of the rotating disk. The rotating disk is located at the lower end of the semi-circular groove. A connecting block is fixedly connected to the edge of the upper surface of the rotating disk. The outer walls of the front and rear ends of the connecting block are rotatably fitted with the inner wall of the semi-circular groove. A push block is fixedly connected to the upper end of the connecting block. The lower end of the push block is rotatably fitted with the upper surface of the front end of the mounting base.

[0010] Through the above technical solution, the design of the second servo motor, connecting rod and rotating disk enables the connecting block to drive the push block to move along the trajectory of the semi-circular groove, allowing the push block to adapt to pipes with different bending requirements and improving the adaptability of the equipment. In addition, the fixing rod and limiting groove provide an additional fixing point for the pipe, ensuring that the pipe will not be displaced during the bending process and improving the stability of the bending process.

[0011] Furthermore, a PLC control panel is fixedly connected to the outer wall of one side of the front end of the mounting base;

[0012] The above technical solution uses a PLC control panel to control the operation of the entire equipment.

[0013] Furthermore, one side of the first servo motor is fixedly connected to the inner wall of one side of the protective shell;

[0014] The above technical solution uses a protective shell to protect the internal first servo motor from external factors.

[0015] Furthermore, the two sides of the outer wall of the bidirectional threaded rod at the rear end are rotatably connected to the two sides of the inner wall of the first mounting groove, the outer walls of the sliding blocks are all slidably attached to the inner wall of the first mounting groove, and the lower surfaces of the clamping blocks are all slidably attached to the upper surface of the rear end of the mounting base.

[0016] The above technical solution and design make the clamping process of the clamping block more stable.

[0017] Furthermore, the inner wall of the sliding block on one side is threadedly connected to the outer wall of the bidirectional threaded rod, and the inner wall of the sliding block on the other side is slidably fitted to the outer wall of the guide rod;

[0018] Through the above technical solution, this design achieves a stable movement process for the sliding block.

[0019] Furthermore, the lower end of the fixing rod is fixedly connected to the upper surface of the mounting base;

[0020] The above technical solution provides an additional fixing point for the pipe by means of the limiting groove on the fixing rod, ensuring that the pipe will not be displaced during the bending process.

[0021] This utility model has the following beneficial effects:

[0022] 1. The present invention proposes a pipe bending machine push-bending structure, which uses a first servo motor to drive a bidirectional threaded rod to realize the relative horizontal movement of the clamping block to automatically clamp the pipe, thereby controlling the clamping position and bending start point of the pipe.

Two first mounting grooves 203 are formed at the rear end of the upper surface of the mounting base 2. A protective shell 202 is fixedly connected to the rear end of one side of the outer wall of the mounting base 2. A first servo motor 3 is disposed inside the protective shell 202.

The support block 204 is fixedly connected to the middle of the upper surface of the rear end of the mounting base 2. By driving the bidirectional threaded rod 301 through the first servo motor 3, the clamping block 304 can move relative to each other in the horizontal direction to automatically clamp the pipe, thereby controlling the clamping position and the starting point of bending of the pipe. The guide rod 302 ensures the linear movement of the sliding block 303 and the clamping block 304, preventing the clamping block 304 from shifting or rotating during the movement. The automated design reduces manual operation and improves production efficiency.

In addition, the fixing rod 4 and the limiting groove 401 provide an additional fixing point for the pipe, ensuring that the pipe will not be displaced during the bending process, thus improving the stability of the bending process.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A PLC control panel 201 is fixedly connected to the outer wall of one side of the front end of the mounting base 2. The PLC control panel 201 is used to control the operation of the entire device. One side of the first servo motor 3 is fixedly connected to the inner wall of one side of the protective shell 202. The protective shell 202 is used to protect the first servo motor 3 from external factors. The two sides of the outer wall of the rear bidirectional threaded rod 301 are rotatably connected to the two sides of the inner wall of the first mounting groove 203, respectively. The outer walls of the sliding blocks 303 are all slidably fitted against the inner walls of the first mounting groove 203. The lower surface of the clamping blocks 304 is all in contact with the inner wall of the first mounting groove 203. The upper surface of the rear end of the mounting base 2 slides and fits, which makes the clamping process of the clamping block 304 more stable. The inner wall of one side of the sliding block 303 is threadedly connected to the outer wall of the bidirectional threaded rod 301, and the inner wall of the other side of the sliding block 303 slides and fits with the outer wall of the guide rod 302. This design realizes the stable movement of the sliding block 303. The lower end of the fixing rod 4 is fixedly connected to the upper surface of the mounting base 2. The limiting groove 401 on the fixing rod 4 provides an additional fixing point for the pipe, ensuring that the pipe will not be displaced during the bending process.

[0035] Working principle: First, the rear end of the pipe to be bent is placed on the support block 204, and the front end of the pipe is inserted into the limiting groove 401 on the fixing rod 4. Then, the PLC control panel 201 is operated to start the device, causing the first servo motor 3 to drive the bidirectional threaded rod 301 to rotate, which in turn causes the sliding blocks 303 on both sides to move horizontally along the first mounting groove 203 under the constraint of the guide rod 302. The upper end of the sliding block 303 is fixedly connected to the lower surface of the clamping block 304, so the clamping block 304 also moves horizontally, thereby realizing automatic clamping of the pipe. The fixing rod 4 and the limiting groove 401 at the middle of the front end of the clamping block 304 further restrict the movement of the pipe and ensure the stability of the clamping. Second, the second servo motor 5 drives the connecting rod 501 to rotate. The upper end of the connecting rod 501 is fixedly connected to the rotating disk 502, thereby driving the pipe to rotate. The rotating disk 502 rotates within the semi-circular groove 206 at the front end of the mounting base 2. A connecting block 503 is fixedly connected to the edge of the upper surface of the rotating disk 502. The outer walls of the front and rear ends of the connecting block 503 rotate and fit against the inner wall of the semi-circular groove 206. A push block 504 is fixedly connected to its upper end. Therefore, as the rotating disk 502 rotates, the connecting block 503 drives the push block 504 to move along the trajectory of the semi-circular groove 206, applying a pushing force to the clamped pipe. Under the combined action of the rotating disk 502 and the push block 504, the pipe is bent and shaped according to the preset bending radius and angle. Throughout the process, the PLC control panel 201 controls the two servo motors to ensure that all components work together to achieve automated pipe bending. The protective shell 202 protects the internal first servo motor 3 from external factors and extends the service life of the equipment.
