Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, and in particular to a servo-driven pipe end forming component. Background Technology
[0002] Pipe end forming equipment, as a specialized tool for processing the ends of metal or non-metal pipes, plays a vital role in the pipe processing industry. It can perform various key processes, such as flaring, necking, pipe reduction, flanging, and upsetting. These processes can precisely change the shape and size of the pipe ends according to different production needs to meet diverse industrial applications. Especially in the pipe end forming process of air conditioning and refrigeration heat exchange equipment, the ends of some round pipes often need to be flattened. Pipe end forming equipment plays an indispensable role in this step, ensuring that the pipe ends meet specific design requirements, thereby guaranteeing the normal operation and performance of the air cooling equipment.
[0003] Chinese patent publication CN216989372U discloses a pipe end forming device. This device mainly consists of a clamping mechanism, a forming mechanism, and a shaping assembly. The clamping mechanism includes a pair of V-blocks, with a positioning mandrel positioned in the middle of each V-block, thus stably fixing the pipe during processing. The forming mechanism includes a pair of pressure plates that can move simultaneously in the same or opposite directions to perform the forming operation on the pipe end. Furthermore, the forming mechanism is movably positioned between the clamping mechanism and the shaping assembly, facilitating continuous processing of the pipe.
[0004] However, from the overall structure of the device, the clamping mechanism and the shaping component are separately mounted on the base plate. While this arrangement ensures the independence of each component to a certain extent, it also brings obvious drawbacks: it results in an excessively large space occupied by the entire device, leading to a waste of space resources, and the low integration due to the dispersed placement of the components. Based on the above analysis of the problems existing in the tube end forming device, this utility model believes it is necessary to disclose a servo-driven tube end forming component, which, through optimized design, improves the space utilization and integration of the equipment. Utility Model Content

[0011] Furthermore, a T-shaped transmission plate is slidably disposed on the main frame component, the driving component is connected to the upper end of the T-shaped transmission plate, and the lower end of the T-shaped transmission plate is connected to the forming mandrel.
[0012] Furthermore, it also includes a mounting plate, on which the main frame component is mounted.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model's servo-driven tube end forming assembly integrates a mandrel forming module and a clamping execution module onto the main frame component.

[0026] A. Pipes. Detailed Implementation
[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0028] like Figures 1 to 6The image shows a servo drive tube end forming assembly for which this utility model is claimed. It includes a frame main component 1, on which a mandrel forming module 2 and a clamping execution module 3 are disposed. The difference from the traditional structure is that both the mandrel forming module 2 and the clamping execution module 3 are disposed on the frame main component 1, which helps to improve space utilization and the integration of the equipment.
[0029] The mandrel forming module 2 includes a drive component 201 fixed on the frame main component 1, and the movable end of the drive component 201 is connected to the forming mandrel 202. A T-shaped transmission plate 203 is slidably arranged on the frame main component 1. The drive component 201 is connected to the upper end of the T-shaped transmission plate 203, and the lower end of the T-shaped transmission plate 203 is connected to the forming mandrel 202. In this embodiment, the drive component 201 is a cylinder. The drive component 201 pushes the T-shaped transmission plate 203, thereby controlling the forming mandrel 202 to extend forward and retract.
[0030] The clamping execution module 3 includes dynamic clamping blocks 301 located on both radial sides of the forming mandrel 202. The dynamic clamping blocks 301 are movably and closably mounted on the frame main component 1. The frame main component 1 includes a front end plate 101, in which a front positioning plate 102 is provided. The front positioning plate 102 has a mandrel guide hole 1021 that corresponds to the forming mandrel 202. Under the action of the driving component 201, the forming mandrel 202 is controlled to move within the mandrel guide hole 1021. The mandrel guide hole 1021 helps improve the smoothness of the movement of the forming mandrel 202. A clamping window 1011 is provided between the front end plate 101 and the front positioning plate 102. The dynamic clamping blocks 301 are movably mounted within the clamping window 1011. The clamping window 1011 is rectangular, and its lateral width is greater than the lateral width of the dynamic clamping blocks 301, thus allowing the dynamic clamping blocks 301 to have lateral movement space.
[0031] The dynamic clamping block 301 is connected to the inclined wedge block 302, and the inclined wedge block 302 is connected to the first servo drive screw module 303. An inclined linkage structure is formed between the dynamic clamping block 301 and the inclined wedge block 302. Specifically, the inclined linkage structure includes an inclined guide rail 3021 provided at the front end of the inclined wedge block 302 and an inclined groove 3011 provided on the dynamic clamping block 301. The inclined guide rail 3021 and the inclined groove 3011 are slidably assembled. The dynamic clamping block 301 is also provided with an anti-disengagement stop 3012 to limit the dynamic clamping block 301 from disengaging from the clamping window 1011.
[0032] The cross-sectional area of the inclined guide rail 3021 is trapezoidal, and the inclined groove 3011 is a dovetail groove that matches the shape of the inclined guide rail 3021, so that the two are assembled and joined tightly.
[0033] Therefore, based on the above structural description, in the working state, the tube to be processed is aligned with the forming mandrel 202. The driving component 201 drives the forming mandrel 202 to be axially inserted into the inner cavity of the tube A for support. The first servo drive screw module 303 drives the wedge block 302 to move. Under the constraint of the inclined plane linkage structure, the dynamic clamping block 301 closes, thereby clamping and shaping the tube A, forming it as shown above. Figure 6 The tube A shape is shown. In this embodiment, there are two forming mandrels 202 arranged vertically, therefore... Figure 6 The pipe A shown has two holes. The forming mandrel 202 is fixed on the T-shaped transmission plate 203. For pipes that need to be processed with different numbers of holes, the T-shaped transmission plate 203 with different numbers of forming mandrels 202 can be replaced. Correspondingly, the front positioning plate 102 is detachably fixed to the frame main component 1 by bolts, so that a front positioning plate 102 with different numbers of mandrel guide holes 1021 can be selected.
[0034] It also includes a mounting plate 4, with the main frame component 1 mounted on the mounting plate 4. The mounting plate 4 is also equipped with a pipe end forming module 5, which is arranged side by side with the main frame component 1. The pipe end forming module 5 is equipped with a hole-expanding mold or a hole-shrinking mold 501. The pipe end forming module 5 also has a motor rotating component to drive the hole-expanding mold or hole-shrinking mold 501 to rotate. That is, the mounting plate 4 integrates the functions of expanding or shrinking the hole of the pipe end and clamping and forming.
[0035] Mounting plate 4 is slidably connected to X-axis slide 6 via guide rails. A second servo drive screw module 7 is mounted on X-axis slide 6 and connected to mounting plate 4 to drive mounting plate 4 to move. It also includes Y-axis slide 8, on which X-axis slide 6 is slidably connected via guide rails. Y-axis slide 8 and X-axis slide 6 are orthogonally arranged. A third servo drive screw module 9 is mounted on Y-axis slide 8 and connected to X-axis slide 6 to drive X-axis slide 6 to move. This arrangement enables tube end forming module 5, mandrel forming module 2, and clamping execution module 3 to perform two-dimensional motion on a planar surface.
[0036] The aforementioned servo-driven lead screw modules are all lead screw modules driven by servo motors. Taking the connection between the wedge block 302 and the first servo-driven lead screw module 303 as an example, the first servo-driven lead screw module 303 includes a servo motor, a lead screw, and a lead screw nut. The wedge block 302 is connected to the lead screw nut, which is threaded onto the lead screw. The lead screw is connected to the servo motor. Therefore, according to the working principle of the lead screw module, the servo motor ultimately moves the wedge block 302. The structural principles of the other second servo-driven lead screw modules 7 and third servo-driven lead screw modules 9 are similar to those described above and will not be elaborated here. By using servo motor drive, the accuracy and stability of the motion can be improved.
[0037] This utility model's servo-driven tube end forming assembly integrates a mandrel forming module 2 and a clamping execution module 3 onto the main frame component 1. The mandrel forming module 2 provides support for the inner wall of the tube, while the clamping execution module 3 is responsible for clamping and forming the tube. This integrated design effectively improves space utilization and reduces the overall space occupied.
[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
