However, the device does not have a quick demolding mechanism, which makes the demolding work after the copper tube is formed difficult and affects the work efficiency. It needs to be improved.

[0005] Therefore, a forming and processing equipment for copper pipe fittings of refrigeration equipment is proposed. Utility Model Content

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, this utility model embodiment provides a forming and processing equipment for copper pipe fittings of refrigeration equipment, including a processing table 1 and a cylinder 4. A lower mold 2 is installed on the processing table 1, and a water-cooled forming mechanism is connected inside the lower mold 2. A mold closing mechanism is connected to the output end of the cylinder 4. A horizontal plate 7 is also installed on the output end of the cylinder 4, and a U-shaped plate 8 is installed at the bottom of the horizontal plate 7. The U-shaped plate 8 can slide up and down. The processing table 1 has through grooves arranged in the vertical direction on both sides for the U-shaped plate 8 to slide. A forming groove is provided inside the lower mold 2, and a support plate 9 is provided inside the forming groove. A connecting column 10 is slidably installed inside the processing table 1, and a connecting plate 11 is installed at the bottom of the connecting column 10. A spring 12 is sleeved on the connecting column 10, and the spring 12 is located between the processing table 1 and the connecting plate 11.

[0029] In one embodiment, the mold clamping mechanism includes an L-shaped bracket 3, an upper mold 5, and a grouting port 6. The L-shaped bracket 3 is mounted on the processing table 1, and the upper mold 5 is mounted on the output end of the cylinder 4. The upper mold 5 is located above the lower mold 2 and can slide up and down. The grouting port 6 is located on the upper mold 5. Molten copper is injected into the forming groove in the lower mold 2 through the grouting port 6. Under the action of the upper mold 5 and the lower mold 2, the molten copper will form a copper tube after cooling.

[0030] In one embodiment, the water-cooled molding mechanism includes a spiral cooling pipe 13, an inlet pipe 14, an outlet pipe 15, a circulating pump 16, a storage tank 17, and heat dissipation fins 18. The spiral cooling pipe 13 is arranged around the periphery of the molding groove in the lower mold 2. One end of the inlet pipe 14 is connected to the inlet of the spiral cooling pipe 13, and the other end of the inlet pipe 14 is connected to the storage tank 17. The circulating pump 16 is arranged on the inlet pipe 14. One end of the outlet pipe 15 is connected to the spiral cooling pipe 13, and the other end of the outlet pipe 15 is connected to the storage tank 17. The heat dissipation fins 18 are arranged on the storage tank 17.

[0031] In one embodiment, one end of the spring 12 is mounted on the bottom of the processing table 1, and the other end of the spring 12 is mounted on the top of the connecting plate 11. Under the action of the spring 12, the support plate 9 can be driven back to the bottom of the forming groove and complete the reset.

[0032] In one embodiment, the connecting column 10 is installed at the bottom of the support plate 9, and the processing table 1 is provided with a sliding groove for the connecting column 10 to slide up and down. When the cylinder 4 drives the U-shaped plate 8 to rise, during the process of contacting the connecting plate 11 and driving the connecting plate 11 upward, the connecting column 10 moves upward along the processing table 1, and drives the support plate 9 to slide upward along the forming groove. In this process, the internally formed copper tube is lifted and pushed out from the forming groove, achieving the effect of automatic unloading.

[0033] In one embodiment, the coolant reservoir 17 is located below the processing table 1, and the heat dissipation fins 18 are made of copper. Copper has good thermal conductivity, which can accelerate the rapid cooling of the coolant and ensure heat absorption efficiency.

[0034] In one embodiment, the pumping end of the circulating pump 16 is connected to the storage tank 17 via the inlet pipe 14, and the delivery end of the circulating pump 16 is connected to the spiral cooling pipe 13 via the inlet pipe 14. The circulating pump 16 is started, causing the coolant in the storage tank 17 to enter the spiral cooling pipe 13 through the inlet pipe 14.

[0035] In operation, this invention works as follows: First, the cylinder 4 is activated, causing the upper mold 5 to descend and close with the lower mold 2. Then, molten copper is injected into the forming groove of the lower mold 2 through the injection port 6. Next, the circulation pump 16 is activated, driving the coolant in the storage tank 17 through the inlet pipe 14 into the spiral cooling pipe 13. Simultaneously, as the coolant passes through the spiral cooling pipe 13, it rapidly absorbs the heat dissipated by the molten copper through heat conduction, thereby reducing the temperature around the forming groove and improving the forming efficiency of the internal copper tubes. After absorbing heat, the coolant is discharged through the outlet pipe 15 on the other side and finally returns to the storage tank 17. Under the action of the heat dissipation fins 18, the stored coolant can be quickly cooled. The internal coolant of box 17 dissipates heat, ensuring that the coolant temperature approaches normal operating temperature. After the copper tube is formed inside the forming tank, cylinder 4 is activated first, which lifts the upper mold 5. During this process, the U-shaped plate 8 moves upward. As the upper mold 5 rises, the U-shaped plate 8 eventually contacts the connecting plate 11 and lifts the connecting plate 11 upward, thereby causing the connecting column 10 to move upward along the processing table 1 and drive the support plate 9 to slide upward along the forming tank. In this process, the internally formed copper tube is lifted and pushed out of the forming tank, achieving automatic unloading. When cylinder 4 lowers the U-shaped plate 8, the support plate 9 can return to the bottom of the forming tank under the action of spring 12, completing the reset.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
