[0002] Currently, copper foil stamping equipment for heat exchangers is used to stamp copper foil to form the required structure of the heat exchanger. It typically consists of a frame, stamping die, feeding mechanism, drive mechanism, and control system. The working process is as follows: the feeding mechanism transports the copper foil to the stamping die, the drive mechanism provides power to drive the upper die of the stamping die to move downward, and cooperates with the lower die to stamp the copper foil, so that the copper foil forms specific shapes and structures such as fins and flow channels to meet the heat dissipation and fluid flow requirements of the heat exchanger. The control system is used to control the operating parameters of various parts of the equipment, such as stamping speed, pressure, and feeding speed, to ensure the stability of the stamping process and product quality.

[0003] However, the existing technology has obvious shortcomings during application. It lacks a good positioning structure and the function of quick mold assembly and disassembly. During use, the mold is fixed and the positioning mechanism cannot be adjusted according to specific processing needs. When the specifications of the heat exchanger to be processed change, the entire set of equipment often needs to be replaced. Even if the mold can be replaced, the positioning mechanism and the mold assembly and disassembly process are cumbersome and inconvenient. This situation is difficult to adapt to the needs of flexible production and processing, and also leads to high operating costs. Therefore, it is necessary to design a stamping equipment with an adjustable positioning structure and the ability to quickly change molds. Utility Model Content

[0024] The upper module 4 includes a mounting rail 41, which is fixedly mounted on the bottom output end of the hydraulic cylinder 5. An upper mounting plate 42 is slidably connected inside the mounting rail 41. An upper mold 43 is fixedly mounted on the bottom of the upper mounting plate 42. Upper mounting screws 44 are threaded to both ends of the top of the mounting rail 41, with the ends of the upper mounting screws 44 threaded through the mounting rail 41 and the upper mounting plate 42. During operation, the mounting rail 41 is fixed to the bottom output end of the hydraulic cylinder 5. The upper mounting plate 42 is slidably connected to the inside of the mounting rail 41, aligning the upper mold 43 at the bottom of the upper mounting plate 42 with the lower position. The mounting rail is then rotated. The upper mounting screws 44 at both ends of the top of 41 pass through the mounting rail 41 and are threadedly connected to the upper mounting plate 42, thereby fixing the upper mounting plate 42 and the upper mold 43. When the upper mold 43 needs to be replaced, the upper mounting screws 44 are rotated in the opposite direction to disengage it from the upper mounting plate 42, and the upper mounting plate 42 is slid out along the mounting rail 41. After replacing the upper mounting plate 42 and the upper mold 43, they are fixed again by the upper mounting screws 44. During stamping, the output end of the hydraulic cylinder 5 drives the mounting rail 41 and the upper mounting plate 42 to move down, so that the upper mold 43 completes the stamping operation. After the operation is completed, the hydraulic cylinder 5 drives the upper module 4 to reset.

[0025] refer to Figures 1-3 The lower module 3 includes a mounting groove 31, which is located at both ends of the top of the base 1.

A lower mold 35 is fixedly mounted on the top of the lower mounting plate 32. Both the upper mounting screw 44 and the lower mounting screw 34 are hand-tightening screws. The outer corners of the support frame 2 are all rounded. During the application of this device, the mounting groove 31 is located at both ends of the top of the base 1, and the lower mounting plate 32 is slidably connected to the base 1. Inside the mounting groove 31, adjust to the target position. The middle of the fixing bracket 33 at the top front end of the lower mounting plate 32 is threaded with a lower mounting screw 34. Rotate the hand-tightened lower mounting screw 34 so that its end passes through the fixing bracket 33 and is threaded to the top of the base 1 to fix the lower mounting plate 32. When replacing the lower mounting plate 32 and related parts, rotate the lower mounting screw 34 in the opposite direction to disengage it from the base 1 and slide the lower mounting plate 32 out along the mounting groove 31. After replacement, fix it again with the lower mounting screw 34. The outer corners of the support frame 2 are rounded to provide protection during operation. Both the upper mounting screw 44 and the lower mounting screw 34 are hand-tightened for easy manual operation to fix or disassemble.

[0026] refer to Figures 1-3 - Figure 4The positioning mechanism 6 includes a side rail 61, which is fixedly installed on the lower side of the support frame 2. A drive motor 62 is fixedly installed at the rear end of the side rail 61. A lead screw 63 is fixedly installed through the side rail 61 at the output end of the drive motor 62. The two ends of the lead screw 63 have opposite threads. Both ends of the lead screw 63 are threadedly connected to sliders 64. A clamping assembly 65 is fixedly connected to the inner side of the slider 64. The internal cross-sectional shape of the side rail 61 is set to a convex shape, and the cross-sectional shape of the slider 64 is also set to a convex shape. Wear-resistant pads are attached to the outer surface of the slider 64. The clamping assembly 65... 5 includes a clamping rail 651, which is fixedly installed on the side of the slider 64 near the support frame 2. Movable blocks 652 are slidably connected to both ends of the clamping rail 651. A side clamping plate 653 is fixedly installed on the top of the movable block 652, and a fixing arm 654 is fixedly installed on the outer side of the movable block 652. A limit screw 655 is threadedly connected to the lower end of the fixing arm 654, and the end of the limit screw 655 is fixed to the arm 654. The outer side of the clamping rail 651 has equally spaced linearly arranged locking holes 656, and the end of the limit screw 655 is inserted into the locking holes 656. Inside 56, during the use of this device, its side rail 61 is fixed to the lower end of one side of the support frame 2. The output end of the drive motor 62 at the rear end of the side rail 61 passes through the side rail 61 and is fixedly installed with the lead screw 63. The threads at both ends of the lead screw 63 have opposite directions and are both threaded to the slider 64. The clamping assembly 65 is fixedly connected to the inner side of the slider 64. The internal cross-sections of both the side rail 61 and the slider 64 are convex. Wear-resistant pads are attached to the outer surface of the slider 64. When the drive motor 62 is started, its output end drives the lead screw 63 to rotate. Since the threads at both ends of the lead screw 63 have opposite directions, the slider 64 moves along the side rail 61. The internal sliding mechanism moves the clamping assemblies 65 closer to or further apart to adjust their positions. The clamping rail 651 of the clamping assembly 65 is fixed to the side of the slider 64 near the support frame 2. The movable block 652 inside the sliding clamping rail 651 moves the side clamping plate 653 to the corresponding position. The lower end of the fixed arm 654 on the outside of the movable block 652 is threaded with a limiting screw 655. The limiting screw 655 is rotated so that its end passes through the fixed arm 654 and is inserted into the corresponding card hole 656 on the outside of the clamping rail 651, fixing the movable block 652 and the side clamping plate 653, thus completing the copper foil positioning.

[0027] Operating principle and advantages: The upper mounting plate 42 is slidably connected to the inside of the mounting rail 41, aligning the upper mold 43 at the bottom of the upper mounting plate 42 with the lower position. The upper mounting screws 44 at both ends of the top of the mounting rail 41 are rotated so that their ends pass through the mounting rail 41 and are threadedly connected to the upper mounting plate 42, thus fixing the upper mold 43. When the upper mold 43 needs to be replaced, the upper mounting screws 44 are rotated in the opposite direction to disengage it from the upper mounting plate 42, and the upper mounting plate 42 is slid out along the mounting rail 41. After replacing the upper mounting plate 42 and the upper mold 43, they are re-fixed by the upper mounting screws 44. The lower mounting plate 32 is slidably connected to the mounting groove 31 at the top of the base 1. After adjusting it to the target position, the lower mounting screw 34 in the middle of the fixing frame 33 is rotated so that its end passes through the fixing frame 33 and is threadedly connected to the top of the base 1. To fix the lower mounting plate 32, when replacing the lower mold 35, rotate the lower mounting screw 34 in the opposite direction to slide the lower mounting plate 32 out along the mounting groove 31. After replacement, fix it again by the lower mounting screw 34. Start the drive motor 62 at the rear end of the side rail 61 in the positioning mechanism 6. Its output end drives the lead screw 63 to rotate. Since the threads at both ends of the lead screw 63 rotate in opposite directions, the sliders 64 at both ends slide along the inside of the side rail 61 and move closer or further away from each other. Adjust the position of the clamping group 65, slide the movable block 652 inside the clamping rail 651, and drive the side clamping plate 653 to move to the position corresponding to the side of the copper foil. Rotate the limiting screw 655 at the lower end of the fixing arm 654 so that its end is inserted into the corresponding card hole 656 on the outside of the clamping rail 651, fix the position of the movable block 652 and the side clamping plate 653, and complete the clamping and positioning of the copper foil.

[0028] The copper foil is placed on the lower mounting plate 32 of the lower mold 3. The copper foil is positioned by the side clamping plate 653 of the positioning mechanism 6. The hydraulic cylinder 5 is activated, and its output end drives the clamping rail 651 and the upper mounting plate 42 to move downward, so that the upper mold 43 contacts the copper foil on the lower mounting plate 32 and performs stamping. After stamping, the hydraulic cylinder 5 drives the upper mold 4 to reset, releases the clamping group 65 of the positioning mechanism 6, and removes the processed copper foil. The positioning mechanism 6 drives the lead screw 63 to rotate through the drive motor 62, so that the slider 6 4. The clamping assembly 65 moves synchronously to achieve positioning adjustment for copper foils of different widths. The movable block 652 in the clamping assembly 65 slides along the clamping rail 651, and is fixed with the limit screw 655 and the locking hole 656, which can adapt to the clamping requirements of copper foils of different thicknesses, improving the flexibility and accuracy of positioning. The upper module 4 is slidably connected to the clamping rail 651 through the upper mounting plate 42, and is fixed with the upper mounting screw 44, which enables the quick assembly and disassembly of the upper mold 43. The lower module 3 is connected to the mounting groove 31 through the lower mounting plate 32. The sliding connection, combined with the fixing of the lower mounting screw 34, enables quick replacement of the lower mold 35 without additional tools, reducing the time cost of mold replacement. The upper mounting screw 44, lower mounting screw 34, and limit screw 655 are all hand-tightened, allowing operators to operate them directly without auxiliary tools, simplifying the operation process. The external corners of the support frame 2 are rounded to reduce the risk of injury from bumps during operation. The cross-sections of the side rail 61 and the slider 64 are both convex, increasing stability during sliding. The wear-resistant pads attached to the outer surface of the slider 64 reduce wear during long-term use and extend the service life of the positioning mechanism 6. The threaded connection between the upper mounting screw 44 and the lower mounting screw 34 ensures the structural stability after mold installation. Through the adjustable design of the positioning mechanism 6 and the quick mold replacement function, the equipment can adapt to the stamping requirements of copper foil of different specifications of heat exchangers without replacing the entire set of equipment, reducing the investment cost of production equipment and improving the versatility of the equipment.
