Description

Technical Field

[0001] The utility model relates to the technical field of copper tube bending, in particular to a bending device for copper tubes of a refrigeration box. Background Technique

[0002] Copper tube is a kind of non-ferrous metal tube, which is commonly used in tap water pipes, heating and refrigeration pipes. As an installation tube, it has the advantages of being hard in texture, not easy to corrode, high temperature resistance, high pressure resistance, etc., and can be used in different environments. The copper tube combines the advantages of metal and non-metal tubes, and takes the lead in the cold and hot water systems, being the best connecting pipe. The copper tube is fire-resistant and heat-resistant, and can still maintain its shape and strength at high temperatures without aging phenomenon.

[0003] At present, when the equipment for bending copper tubes is in use, the positions for fixing the endpoints of the copper tubes are mostly fixed. When the copper tube is long, the position of the copper tube placement can be adjusted for bending processing. When the copper tube is short, the fixed endpoints prevent the end of the copper tube to be bent from extending to the component for bending processing, resulting in the inability to perform bending processing, making the adaptability of the bending equipment poor. At the same time, the fixing method for the end of the copper tube is still relatively cumbersome, affecting the processing efficiency. Content of the Utility Model

[0026] Through the above scheme, the specific bending process of the copper pipe pushed by the electric push rod 7 is carried out by using the bending mechanism;

[0027] In this embodiment, preferably, the connecting mechanism includes a limiting cylinder 18, a threaded rod 19, a top block 20 and a clamping block 21. Limiting cylinders 18 are fixedly arranged at the bottom ends of both ends of the arc-shaped plate 13.

[0028] Through the above scheme, the addition and fixation work of the arc-shaped plate 13 can be quickly completed by using the connecting mechanism in cooperation with the connecting groove 25 and the clamping groove 26. When fixing the end of the copper pipe to be processed, the operation can be quickly completed only by rotating the knob 27, ensuring the convenience of the application of this device;

[0037] When using the bending device for the copper tube of a refrigeration box of the present embodiment, the position of the support block 9 inside the moving frame 4 is first adjusted according to the length of the bending part of the copper tube, so that the support range of the device is adapted to the length requirement. When making adjustments, it is only necessary to enable the first motor 11 to drive the screw rod 8 to rotate, so that the support block 9 limited by the connection of the guide rod 10 is displaced in the horizontal direction. After completing the position adjustment of the support block 9, one end of the copper tube to be bent is placed on the fitting groove 12 on the support block 9, and the middle end of the copper tube is supported in the placement groove 5 on the moving frame 4, and then the arc plate 13 is buckled on, and the end of the copper tube is fixed by the arc plate 13, so that when the bending process is performed, the end of the copper tube will not be lifted up due to the bending force of the other end. When using the arc plate 13, it is only necessary to align the limiting cylinder 18 with the connecting groove 25 and buckle the arc plate 13 The upper block 20 is moved downwards as the threaded rod 19 rotates, and the contact surface between the upper block 20 and the clamping block 21 is an inclined surface. Therefore, as the upper block 20 moves downwards, the clamping block 21 is displaced in the horizontal direction and embedded in the clamping groove 26, thereby completing the addition and fixation of the arc plate 13. Finally, the electric push rod 7 is enabled to push the moving frame 4 to send the end of the copper tube to be bent into the rotating frame 15, and the rotating frame 15 is driven to rotate by the second motor 17, so that the bending process is completed through the contact of the bending wheel 16. When the copper tube needs to be removed, the upper block 20 is removed by reversely twisting the knob 27, and the clamping block 21 is reset under the action of the spring 23 and disengaged from the clamping groove 26, thereby removing the arc plate 13, and then removing the processed copper tube workpiece.
