Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, in particular to an extrusion molding die for a refrigeration copper tube. Background Art

[0002] Copper pipe is a kind of non-ferrous metal pipe, which is a pressed and drawn seamless pipe. Copper pipe has good electrical and thermal conductivity, and has become the first choice of modern contractors for the installation of tap water pipes and refrigeration pipes in all residential commercial houses. At present, most copper pipes need to be processed with molds. Molds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. There are many types of molds at present, and extrusion molds are one of them.

[0003] After searching, the Chinese patent authorization number CN207414195U discloses a copper tube expanding machine, including a frame, a workbench arranged on the frame, a lower mold is arranged on the workbench, and lower expanding grooves are symmetrically arranged at both ends of the upper surface of the lower mold. An upper mold located directly above the lower mold is arranged on the frame for lifting and lowering, and a first power member for driving the upper mold to lift and lower is arranged between the frame and the upper mold. Upper expanding grooves corresponding to the lower expanding grooves are symmetrically arranged at both ends of the lower surface of the lower mold, and telescopic expansion grooves are symmetrically distributed at both ends of the frame. A expanding die is set up, and a second power component for driving the expanding die to extend and retract is set between the frame and the expanding die. By placing two copper tubes between the lower die and the upper die at the same time, and expanding the two copper tubes at the same time through the two expanding dies, the processing efficiency of the copper tubes can be improved. However, the specifications of the expanding groove are fixed, the steel tubes are not easy to take and place, and manual operation has certain risks. Moreover, only steel tubes of one specification and length can be processed and expanded, which has high limitations. At the same time, the second power component is fixed on the workbench, the stability is not high, and the quality of the extruded finished product is poor.

[0004] Therefore, we proposed a refrigeration copper tube extrusion forming die. Utility Model Content
