Description

Technical Field

[0001] This utility model relates to the field of titanium anode plate processing technology, and in particular to a pneumatic bending machine for titanium anode plates. Background Technology

[0002] This utility model relates to the field of titanium anode plate processing technology, and in particular to a pneumatic bending machine for titanium anode plates. Due to its unique corrosion resistance and electrochemical properties, titanium anodes have shown wide application value in many fields such as electrolysis, electroplating and water treatment. The processing of titanium anodes, especially the bending process, is a key step to ensure product performance and quality. Traditional bending machines face a series of challenges when processing high-performance materials such as titanium anodes.

[0003] Traditional bending machine designs often prioritize versatility, but their precision is insufficient when processing specific materials such as titanium anodes. Because titanium anodes require high consistency in bending angles and shapes, traditional bending machines are prone to deviations during processing, leading to increased product defect rates and material waste. Furthermore, the lack of equipment stability in traditional bending machines often necessitates multiple adjustments and corrections when processing titanium anodes, reducing production efficiency and increasing costs. More importantly, during prolonged processing, deformation of the frame and sliding components in traditional bending machines can easily lead to deflection, further affecting bending accuracy and consistency. Therefore, a pneumatic bending machine for titanium anode plates is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the high requirements for the consistency of bending angle and shape of titanium anodes, the tendency of traditional bending machines to deviate during processing, leading to increased product defect rates and material waste. Furthermore, traditional bending machines often require multiple adjustments and corrections due to insufficient equipment stability, which not only reduces production efficiency but also increases production costs. More importantly, during long-term processing, the deformation of the frame and sliding parts of traditional bending machines can easily lead to deflection deformation, further affecting the bending accuracy and consistency. Therefore, this invention proposes a pneumatic bending machine for titanium anode plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pneumatic bending machine for titanium anode plates includes a frame, a lower die, and an upper die. A mounting block is fixedly connected to one side of the frame. The lower die is fixedly connected to the top of the mounting block. The upper die is located directly above the lower die and is adapted to fit the lower die. Two slide rails are fixedly connected to the top of the inner walls of the frame on opposite sides. A deflection correction mechanism is slidably arranged between the two corresponding slide rails. The deflection correction mechanism is used to correct the deflection deformation generated by the lower die and the upper die during the bending process.

[0007] In one possible design, the deflection correction mechanism includes multiple extension shafts, a U-shaped slider, and a mounting shaft. The U-shaped slider is slidably connected between two corresponding slide rails. The multiple extension shafts are symmetrically distributed on both sides of the U-shaped slider. One end of each extension shaft slides through one side of the U-shaped slider. An L-shaped connecting block is fixedly connected to the top of the U-shaped slider. The mounting shaft is fixedly connected to the top of the frame and slides through the L-shaped connecting block. A common spring is fixedly connected between the bottom of the L-shaped connecting block and the top of the frame. The spring is sleeved on the outer circumference of the mounting shaft.

[0008] In one possible design, a common connecting frame is provided between the two U-shaped sliders, and multiple extension shafts are fixedly connected to both sides of the connecting frame. A mounting plate is fixedly connected to the bottom of the connecting frame, and the upper mold is fixedly connected to the bottom of the mounting plate. Two support blocks are fixedly connected to the top of the mounting plate. A common rotating shaft is fixedly connected between the inner walls of the adjacent sides of the frame, and a driving mechanism for driving the upper mold to press down is rotatably provided on the outer circumference of the rotating shaft.

[0009] In one possible design, the drive mechanism includes two pneumatic cylinders and two pressing levers. The pneumatic cylinders are rotatably connected to the inner wall of the bottom of the frame, and the pressing levers are rotatably connected to the outer wall of the circumference of the rotating shaft. One end of the bottom of the pressing lever is rotatably connected to the top of the piston rod of the pneumatic cylinder, and the other end of the bottom of the pressing lever is in contact with the top of the corresponding support block. The bottom of the two pressing levers is fixedly connected to the same connecting rod, and two support mechanisms for supporting the pneumatic cylinders are fixedly provided on the side of the bottom of the frame near the pneumatic cylinders.

[0010] In one possible design, the support mechanism includes an outer tube and a worm gear. The outer tube is fixedly connected to the bottom of the frame, and the worm gear is rotatably connected to the bottom of the frame. The worm gear is located inside the outer tube, and a second support block is slidably connected to the inner wall of the outer tube. A threaded rod is fixedly connected to the bottom of the worm gear and is threadedly connected to the second support block. The same worm is rotatably connected between the inner walls of both sides of the outer tube, and the worm meshes with the worm gear. A motor is fixedly mounted on one side of the outer tube, and the output shaft of the motor rotatably passes through one side of the outer tube. The output shaft of the motor is fixedly connected to one end of the worm. A control mechanism for starting the pneumatic cylinder and the motor is provided on one side of the frame.

[0011] In one possible design, the control mechanism includes a mounting bracket fixedly connected to one side of the frame. A programmable logic controller (PLC) for controlling the start and stop of the pneumatic cylinder and the motor is provided on the inner wall of one side of the mounting bracket. A touch screen for controlling the PLC is provided on one side of the mounting bracket. The PLC is electrically connected to the pneumatic cylinder, the motor, and the touch screen, respectively.

[0012] In one possible design, two support frames are fixedly connected to the bottom inner wall of the frame, and the top of the two support frames is fixedly connected to the same placement plate. One side of the placement plate is fixedly connected to one side of the lower mold, and the top of the placement plate and the top of the lower mold are on the same horizontal line. The bottom of the frame is provided with multiple casters for easy movement.

[0013] Working Principle: In this application, when users need to use this bending machine, they first move it to a suitable position using the casters at the bottom. Then, by controlling the touchscreen, the programmable logic controller (PLC) starts the motor. The motor's output shaft drives the worm gear to rotate, which in turn drives the worm wheel to rotate through meshing. The worm wheel then drives the threaded rod to rotate, and through its threaded connection with support block two, it moves support block two downwards until the bottom of support block two contacts the ground. The titanium anode plate to be bent is then placed on the placement plate, and the area to be bent is positioned between the lower and upper dies. Next, by controlling the touchscreen, the PLC starts the pneumatic cylinder. The piston rod of the pneumatic cylinder pushes the lower lever to rotate along the shaft, which in turn moves the connecting frame and mounting plate downwards by pressing down support block one, causing the upper and lower dies to engage and bend the titanium anode plate. At this time, the connecting frame will drive the U-shaped slider to move downward along the slide rail through the extension shafts on both sides, and empower the spring through the L-shaped connecting block. After the bending process is completed, the piston rod of the pneumatic cylinder retracts and drives the lower lever to rotate. Then, under the action of the spring force, the upper mold and the lower mold are separated by pushing the L-shaped connecting block and returned to the initial position. Then the next bending process can begin. Since the bending process may cause deflection deformation due to the deformation of the frame and the U-shaped slider, if the bottom of the upper mold is not completely aligned with the groove of the lower mold when the lower mold and the upper mold come into contact with each other to start bending, the upper mold will come into contact with the lower mold during the pressing process, causing the upper mold to drive the connecting frame to move through the mounting plate. Then, the connecting frame moves left and right in the U-shaped slider through the extension shafts on both sides to align the bottom of the upper mold with the lower mold, thereby ensuring the consistency of the titanium anode bending angle along the entire length.

[0014] Beneficial effects: In this utility model, the pneumatic bending machine for titanium anode plates, through the deflection correction mechanism, including components such as an extension shaft, a U-shaped slider, a mounting shaft, and a spring, can effectively correct the deflection deformation of the lower and upper dies caused by the deformation of the frame and sliding parts during the bending process, thereby ensuring the consistency of the bending angle of the titanium anode plate along its entire length, and greatly improving the processing accuracy and product qualification rate;

[0015] In this utility model, the titanium anode plate pneumatic bending machine, through the use of a drive mechanism composed of a pneumatic cylinder and a downward lever, and a support mechanism driven by a motor, achieves precise control and stable support of the bending process, avoiding the problem that traditional bending machines need to be debugged and corrected multiple times due to insufficient equipment stability when processing titanium anodes, thus significantly improving production efficiency and reducing production costs.

[0016] In this utility model, the titanium anode plate pneumatic bending machine realizes intelligent control of the bending machine by setting a control mechanism composed of a programmable logic controller and a touch screen. Users can conveniently set and adjust bending parameters through the touch screen and monitor the bending process in real time, which greatly improves the convenience of operation and the automation level of the equipment.

[0017] In this invention, a deflection correction mechanism, including components such as an extension shaft, a U-shaped slider, a mounting shaft, and springs, can effectively correct the deflection deformation of the lower and upper dies caused by the deformation of the frame and sliding parts during the bending process. This ensures the consistency of the bending angle along the entire length of the titanium anode plate, greatly improving processing accuracy and product qualification rate. The use of a drive mechanism composed of a pneumatic cylinder and a downward lever, along with a motor-driven support mechanism, achieves precise control and stable support of the bending process. This avoids the problem of traditional bending machines requiring multiple adjustments and corrections due to insufficient equipment stability during titanium anode processing, significantly improving production efficiency and reducing production costs. Furthermore, the use of a control mechanism composed of a programmable logic controller and a touchscreen enables intelligent control of the bending machine. Users can conveniently set and adjust bending parameters and monitor the bending process in real time via the touchscreen, greatly improving operational convenience and the automation level of the equipment.
