Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, specifically a pipe bending machine device for bending pipes up and down on the machine head. Background Technology

[0002] The pipe bending machine is a device used to bend pipes into curves in the vertical direction. Vertical bending is a pipe processing technology that refers to bending pipes in the vertical direction to form pipes with a certain arc or angle. This processing method is very common in industrial manufacturing, especially in situations where pipes need to be processed into complex shapes to meet specific functional or spatial layout requirements.

[0003] During the processing and application of upper and lower bends, the curvature of the bends at both ends of some pipes may vary depending on actual needs. For example, in the installation of a pipeline system, if space is limited or it is necessary to connect with equipment in different directions, it may be necessary to have a larger bend at one end and a smaller bend at the other end. This design can better adapt to complex installation environments and achieve the optimal layout of the pipeline system.

[0004] In current pipe bending processes, when different arcs or angles of bidirectional bending are required, it is usually necessary to change to a special mold. This operation is quite cumbersome. Specifically, the operator needs to first remove the old mold from the equipment and then install a suitable mold. The entire replacement process not only increases the operation time and reduces production efficiency, but also requires the operator to have skilled and experienced personnel to ensure the accuracy of mold replacement and the normal operation of the equipment. Therefore, a pipe bending machine device with a machine head for bidirectional bending is proposed to address the above problems. Utility Model Content

A second wheel mold 47 is rotatably connected to the outside of the center roller 46.

[0030] As a further implementation of this solution, the fixing component 2 includes a side plate 21. A fixing plate is fixedly connected to the right end of the side plate 21. A first hydraulic rod 23 is fixedly connected to the rear end of the fixing plate of the side plate 21. A first clamping plate 22 is fixedly connected to the right side of the side plate 21. A dovetail-shaped slide groove 25 is opened on the inner side of the side plate 21. A second clamping plate 24 is fixedly connected to the rear end of the first hydraulic rod 23. A dovetail-shaped slider is fixedly connected to the left side of the second clamping plate 24. The dovetail-shaped slider of the second clamping plate 24 is slidably connected to the inner side of the dovetail-shaped slide groove 25. Through the above settings, the second clamping plate 24 can move stably. Then, through the cooperation of the second clamping plate 24 and the first clamping plate 22, the effect of fixing the pipe is achieved, and the stability of the pipe is improved when bending the pipe.

[0031] As a further implementation of this solution, the upper and lower ends of the side plate 21 are provided with sliding grooves. The fixed housing 32 is slidably connected to the inner side of the anti-detachment slide 26. The number of fixed housings 32 is the same as the number of anti-detachment slides 26. The front end of the first electric telescopic rod 31 is fixedly connected to the inner side of the anti-detachment slide 26. The top and bottom ends of the fixed housing 32 are fixedly connected with limit sliders. The inner side of the fixed housing 32 is provided with an installation groove. The first electric telescopic rod 31 and the second electric telescopic rod 35 are on the same horizontal plane. Through the above settings, the first electric telescopic rod 31 can control the position of the fixed housing 32. With the cooperation of the second electric telescopic rod 35, the rotation range of the entire pipe bending assembly 4 can be controlled, thereby controlling the limited bending range of the pipe. At the same time, the cooperation of the second electric telescopic rod 35 and the first electric telescopic rod 31 improves the bending accuracy of the pipe and ensures the quality of the finished product.

[0032] As a further implementation of this solution, the inner side of the fixed box 41 is provided with a groove, the inner side of the first wheel mold 43 is a hollow structure, and a bearing is fixedly connected to the inner side of the first wheel mold 43. The structure of the second wheel mold 47 is the same as that of the first wheel mold 43. The second hydraulic rod 45 is an inclined structure. The left and right ends of the fixed box 41 are provided with inclined grooves 48, and the center roller 46 is embedded in the inner side of the inclined grooves 48. Through the above settings, the angle of local bending of the pipe can be controlled. At the same time, the cooperation between the first wheel mold 43 and the second wheel mold 47 ensures the smoothness of pipe bending and provides a strong guarantee for achieving efficient and precise bending operations, further improving the performance and practicality of the device.

[0033] Workflow: When bending the pipe at both ends simultaneously with different arcs or angles, two electric telescopic rods, the first electric telescopic rod 31 and the second electric telescopic rod 35, are activated simultaneously according to the required arc or angle of bending at the top and bottom of the pipe. If the first electric telescopic rod 31 extends, the second electric telescopic rod 35 retracts. The structure and dimensions of the first electric telescopic rod 31 are the same as those of the second electric telescopic rod 35. When the first electric telescopic rod 31 is activated, it will drive the fixed housing 32 to move. The fixed housing 32 slides inside the anti-detachment slide rail 26. The movement of the second electric telescopic rod 35 will drive the fixed box 41 to move. After adjustment is completed... The fixed box 41 remains in its original position, requiring the servo motor 33 to change position. The pipe is placed between the first clamping plate 22 and the second clamping plate 24, with appropriate distance between the upper and lower ends. It is then inserted between the upper and lower ends of the first wheel mold 43 and the second wheel mold 47. The first hydraulic rod 23 is activated to push the second clamping plate 24 backward. The second clamping plate 24 is slidably connected to the dovetail slide groove 25 via a dovetail slider, which improves the stability of the second clamping plate 24 during movement and prevents it from detaching from the side plate 21. Once the pipe is fixed by the second clamping plate 24 and the first clamping plate 22... Then, the second hydraulic rod 45 is activated and extends, pushing the center roller 46 and the second die 47 forward and downward. The center roller 46 slides inside the inclined groove 48. The tube is bent by the compression of the tube by the second die 47 and the limiting of the tube by the first die 43. The movement range of the second die 47 is offset from that of the first die 43. By extending the length of the second hydraulic rod 45, the local curvature or angle of the tube is bent. After the second hydraulic rod 45 extends to the specified length, it retracts and drives the second die 47 to reset. The servo motor 33 is then activated to drive the extension via the main shaft. Block 34 and the second electric telescopic rod 35 rotate simultaneously. The second electric telescopic rod 35 drives the entire pipe bending assembly 4 to rotate around the main shaft of the servo motor 33. When the pipe bending assembly 4 rotates to the specified arc or angle, the second hydraulic rod 45 is activated to continue bending the pipe. The above work is repeated until the pipe is bent to the specified arc or angle. Through the working principle of the above device, the device can bend the pipe at both ends simultaneously, improving the bending efficiency and production efficiency. At the same time, the angle and arc of the pipe bending at both ends can be adjusted without transferring the pipe or changing the mold, thus improving the production quality.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
