[0002] In modern manufacturing, pipes, as essential components for fluid transport and structural connections, are widely used in numerous fields such as refrigeration and air conditioning, automobile manufacturing, home appliances, hydraulics, and pneumatics. With the rapid pace of product updates and the diversification of market demands, production lines often need to switch between processing different specifications and orientations of pipes within short periods to meet the requirements of multi-variety, small-batch, and mixed-line production. Pipe end forming is one of the key processes in pipe processing. It involves using molds to flare, reduce, flange, or shape the pipe ends for subsequent assembly and connection. Due to the diversity of pipe specifications and forming types, the forming molds must correspond one-to-one with the pipe type.

[0003] However, conventional pipe end forming mechanisms typically use bolts and other fasteners to rigidly connect the molds to the forming spindle or mold base. When replacing them, multiple fasteners need to be manually disassembled and installed, which is cumbersome and time-consuming. For pipes of different specifications and sizes, corresponding mold bases, clamps and material guiding components also need to be replaced, which wastes a lot of time, reduces production efficiency and equipment utilization.

[0004] Therefore, it is necessary to invent a tube end forming mechanism that allows for quick mold changes to solve the above problems. Utility Model Content

Combined with a protective layer, it ensures that the pipe does not wobble when clamped and avoids scratches on the pipe surface caused by rigid clamping. This expands the range of pipes that can be adapted to while reducing the workload of manually replacing clamps and improving work efficiency.

[0016] 3. In this utility model, the positioning component achieves automatic positioning of the pipe through a servo motor, screw, and positioning push plate, eliminating the need for manual alignment. The positioning accuracy is precisely controlled by the PLC controller, avoiding deviations and errors caused by manual positioning. At the same time, the PLC controller coordinates the control of components such as the servo motor, cylinder, and laser displacement sensor, realizing full automation of positioning, fixing, mold changing, and processing. Operators only need to start the program, replenish and remove the pipe, resulting in a low operating threshold and significantly improved processing consistency, reducing the scrap rate caused by differences in manual operation.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a pipe end forming mechanism with quick mold change capability, including an operating table assembly 1. The operating table assembly 1 includes an operating table body 11 with a slot 12 on its surface. A laser displacement sensor 15 (model GS-SA030NX / GS-SA030PX) is installed on the operating table body 11 via a fixing rod 14. The operating table assembly 1 also includes a PLC controller 13 fixedly connected to the operating table body 11. The PLC controller 13 is electrically connected to various electrical components. A support rod 16 is also fixedly connected to the bottom of the operating table body 11. A connecting plate 17 is fixedly connected to the bottom of the support rod 16. Two sets of fixing mechanisms 2 are provided in the middle of the operating table body 11 for fixing and clamping pipes of different specifications. A positioning component 3 for automatically positioning the pipe is provided on one side of the fixing mechanism 2. A quick mold change assembly 5 for quickly changing molds and cooperating with a drive mechanism 4 to process the pipe is provided on the other side of the fixing mechanism 2.

[0026] Therefore, the operator connects the connecting plate 17 of the bottom support rod 16 of the main body 11 of the operating table to the connecting part to ensure the overall stability of the equipment and avoid shaking during processing.

[0027] Specifically, such as Figure 2 and Figure 3As shown, the fixing mechanism 2 includes a fixing frame 21 fixedly connected to the top of the operating table body 11, and a first cylinder 22 and a second cylinder 23 fixedly connected to the top of the fixing frame 21 and the operating table body 11 respectively. The output ends of the first cylinder 22 and the second cylinder 23 are both fixedly connected to a fixing seat 23 with a V-shaped groove on the surface. The surface of the fixing seat 23 is also fixedly connected to an anti-slip protective layer 24. The positioning component 3 includes a sliding limit groove 31 opened on the surface of the operating table body 11, and a servo motor 33 fixedly connected to one end of the operating table body 11. A screw 32 is rotatably connected inside the sliding limit groove, and a positioning push plate 34 is threadedly sleeved on the outside of the screw 32. A reinforcing rib 35 is fixedly connected to the side of the positioning push plate 34 away from the fixing mechanism 2.

[0028] Therefore, during use, the operator first places the pipe to be processed in the V-groove of the bottom fixed seat 23 and abuts one end of the pipe against the positioning plate. Then, the servo motor 33 is started to drive the screw 32 to rotate. The rotation of the screw 32 drives the positioning plate to move and pushes the pipe to move synchronously until the pipe moves to the preset reference position. The laser displacement sensor 15 assists in detecting the position of the pipe end to ensure positioning consistency. After positioning is completed, the servo motor 33 stops rotating, and the positioning push plate 34 remains in the positioning state. The rigidity of the push plate is enhanced by the reinforcing rib 35. After positioning is completed, the PLC controller 13 starts the first cylinder 22. The cylinder output end drives the fixed seat 23 with the V-groove on the surface to move towards each other. The lower fixed seat 23 is pushed up, and the upper fixed seat 23 is pressed down until the inner wall of the V-groove is tightly attached to the outer wall of the pipe to clamp and fix the pipe. The reinforcing rib 35 and the anti-slip protective layer 24 work together to prevent the pipe from sliding during processing.

[0029] Specifically, such as Figure 4 and Figure 5As shown, the quick-change mold assembly 5 includes a rotating shaft 51 rotatably connected to the drive mechanism 4 via a bearing seat. One end of the rotating shaft 51 is fixedly connected to a rotating frame 52 with multiple evenly distributed sliding grooves 53 on its surface. Sliding blocks 54 are slidably disposed within the sliding grooves 53. A moving plate 55 is fixedly connected to the top of each sliding block 54. Mold heads 56 adapted to different processing requirements are fixedly connected to one end of each sliding block 54. The other end of the rotating shaft 51 is fixedly connected to an adjusting block 57 with multiple through holes 58 on its surface. Bolts 59 are slidably fitted inside the through holes 58. The drive mechanism 4 includes a... The mounting plate 41 connected to the main body 11 of the operating table is disassembled. A fixing plate 42 is fixedly connected to the mounting plate 41. The fixing plate 42 is rotatably connected to the rotating shaft 51. A second cylinder 43 with a U-shaped block 44 fixedly connected to the output end is provided on the top of the fixing plate 42. A limiting block 45 with a limiting hole 46 on its surface is also fixedly connected to the mounting plate 41. The limiting hole 46 matches the size of the bolt 59. The highest moving plate 55 is initially located inside the opening of the U-shaped block 44. The initial state of the mold head 56 and the tube are located on both sides of the laser displacement sensor 15 after being positioned by the positioning component 3.

[0030] Therefore, when the mold head 56 needs to be replaced, the operator unscrews the bolt 59 in the limiting block 45 and disengages it from the adjusting block 57. Then, the operator rotates the adjusting block 57 to drive the rotating shaft 51 and the rotating frame 52 to rotate until the mold head 56 to be used rotates to the highest position. Then, the operator inserts the bolt 59 back into the through hole 58 in the adjusting block 57 and threadedly connects it with the limiting hole 46 for limiting. At this time, the operator opens the second cylinder 43 to drive the U-shaped block 44 to move. One end of the U-shaped block 44 drives the moving plate 55 and the sliding block 54 to move. The movement of the sliding block 54 drives the mold head 56 to move and perform processing on the tube end. During the operation, according to the processing requirements, the output end of the cylinder and the stroke of the mold head 56 are controlled by the laser displacement sensor 15 and the PLC controller 13. After the processing is completed, the second cylinder 43 is controlled to retract and drive the U-shaped block 44 and the mold head 56 to disengage from the tube end.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
