Description

Technical Field

[0001] This utility model relates to the field of spiral tube processing technology, specifically to a spiral tube processing mold based on a CNC tube bending machine. Background Technology

[0002] In the production of mechanical parts, bending of pipes is frequently involved. For example, bending of pipes is required in the production and processing of automotive air conditioning parts and robot products. The coiled tube used in pipe bending, also known as a spiral tube or spring tube, is a special type of pipeline. It cleverly compresses the connecting line with varying distances into a spiral shape. This design allows the coiled tube to expand and contract automatically when the distance between the equipment interface changes, reducing storage space and facilitating storage and handling. Coiled tubes are often used between two pieces of equipment, especially when the distance between the connection ports is not fixed, making them particularly convenient to use.

[0003] In the existing technology, one method is manual pipe bending, which is not only labor-intensive but also difficult to control the bending angle of the pipe fittings, resulting in poor consistency. The other method is mechanical pipe bending. Existing CNC pipe bending machines can realize pipe feeding and pipe deflection according to production requirements. However, when processing coiled pipes, the existing molds cannot smoothly pick up the material. Therefore, this technical solution is proposed for improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing spiral tube processing molds, which are inconvenient for material handling, and to provide a spiral tube processing mold based on a CNC tube bending machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spiral pipe processing mold based on a CNC pipe bending machine, comprising an adapter plate disposed on the machine tool, a pressing device for abutting the pipe disposed on the side of the adapter plate, a support block disposed on the side of the pressing device, and a clamping head and a pipe bending wheel disposed on the upper part of the support block for clamping the pipe.

[0006] Furthermore, the adapter plate is vertically arranged, and the pressing device includes a pressing plate that is detachably connected to the adapter plate, with a groove on the side of the pressing plate for accommodating the pipe.

[0007] Furthermore, the tail of the clamping head is provided with a lateral drive device for driving the clamping head to open and close with the bending wheel, and the lateral drive device is located on the side of the support block.

[0008] Furthermore, a rotating shaft is provided at the middle position of the bending wheel, the lower part of the bending wheel is connected to the support block, and a rotation drive device for driving the support block to rotate along the rotating shaft is provided at the bottom of the support block.

[0009] Furthermore, a first forming block is provided at the bottom of the bending wheel, and a second forming block is provided at the top of the bending wheel, with an end cap detachably provided at the top of the second forming block.

[0010] Furthermore, the bottom of the end cap and the upper part of the second molding block are combined to form a molding groove, and the top of the end cap is provided with a connecting hole, and a pin is detachably provided inside the connecting hole.

[0016] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] See Figures 1 to 3This utility model discloses a coiled pipe processing mold based on a CNC pipe bending machine. It mainly includes an adapter plate 1 mounted on a CNC machine tool (in this embodiment, the CNC machine tool is CNC). A cylinder is mounted on the back of the adapter plate 1 to push and pull the adapter plate 1 on a horizontal plane, simultaneously assisting in pipe bending and improving performance. On the front of the adapter plate 1, a pressure mold device is provided to abut against the pipe. The main function of the pressure mold device is to assist in fixing the pipe, ensuring the stability of the pipe clamped on the CNC machine tool. The pressure mold device includes a pressure template 2 detachably connected to the adapter plate 1. The side of the pressure template 2 has a groove 201 for accommodating the pipe. One or more pressure templates 2 can be selected according to the processing position. The design of the groove 201 allows the pipe to fit tightly against the pressure template 2, ensuring the accuracy of the bending angle. The pressure template 2 and the adapter plate 1 are connected by bolts, allowing for different installation angles to meet various processing requirements and increase applicability.

[0018] Support blocks 3 are provided on the sides of the pressing template 2 and the adapter plate 1. A clamping head 4 and a bending wheel 5 for clamping the pipe are provided on the upper part of the support block 3. The clamping head 4 is used to clamp the pipe before bending to prevent it from sliding or deforming during the bending process. The bending wheel 5 is responsible for bending the pipe into the required spiral shape. In order to drive the opening and closing of the clamping head 4 and the bending wheel 5, a transverse drive device is provided at the tail of the clamping head 4. When the clamping head 4 and the bending wheel 5 come into contact, one end of the pipe is clamped. The transverse drive device is located on the side of the support block 3. The clamping and releasing of the pipe is achieved by driving the movement of the clamping head 4, so that the clamping position can be flexibly adjusted when the mold processes pipes with different bending positions, ensuring bending quality and improving bending effect.

[0019] A pivot is located in the middle of the bending wheel 5. The lower part of the bending wheel 5 is connected to the support block 3. A rotation drive device is located at the bottom of the support block 3 to drive the support block 3 to rotate along the pivot. After the clamping head 4 clamps one end of the pipe, the rotation drive device drives the rotation of the support block 3 to drive the bending wheel 5 to rotate, thereby achieving pipe bending. To further improve bending accuracy and mold applicability, a first forming block 501 is located at the bottom of the bending wheel 5, and a second forming block 502 is located at the top of the bending wheel 5. Both the first forming block 501 and the second forming block 502 are provided with forming grooves. The upper part is detachably provided with an end cap 503. The end cap 503 and the second forming block 502 are combined to form a forming groove. The shape of the forming groove matches the required shape of the coiled tube. A connecting hole 504 is provided on the top of the end cap 503. A pin is detachably provided inside the connecting hole 504. The pin is used to fix the upper position of the end cap 503 and the second forming block 502. The design of the pin also makes it easy to disassemble and replace the end cap 503. After processing, the end cap 503 can be opened from the top of the bending wheel 5, and the processed coiled tube can be taken out from the bending wheel 5, which greatly reduces the processing difficulty and improves the processing efficiency.

[0020] In practical operation, the pipe to be processed is first clamped on the clamping device of the CNC machine tool, so that the pipe is clamped horizontally. Then, the pipe is sent forward, and the adapter plate 1 and the pressure plate 2 are conveyed forward. The transverse drive device drives the clamping head 4 to clamp the pipe inside the forming groove on the first forming block 501 of the bending wheel 5. Then, the rotation drive device is started to drive the support block 3, the bending wheel 5 and the clamping head 4 to rotate together, so that the pipe is gradually bent into a U-shape under the action of the pressure plate 2 and the bending wheel 5. Then, the support block 3 is reset, the clamping head 4 is released, the support block 3 is lowered, and the pipe is clamped to the second forming block 5. Inside the forming groove of 02, the clamping device of the CNC machine tool rotates the pipe upward at a certain angle, so that the other end of the pipe is slightly higher than the forming groove on the second forming block 502. Then the clamping head 4 clamps it, and the support block 3 rotates. Through multiple small-angle bends, the clamping device on the machine tool drives the pipe to rotate upward, thereby processing the pipe into a coiled pipe. This ensures that the shape and size of the coiled pipe meet the design requirements. After processing, the end cap 503 is removed from the top, and the coiled pipe can be quickly removed. It has the advantages of simple structure, convenient operation, and high processing accuracy, which improves production efficiency and product quality.
