Description

Technical Field

[0001] The utility model relates to the field of metal additive manufacturing, in particular to a wire metal printing auxiliary cooling device. Background Art

[0002] Wire metal printing uses metal wire as raw material and is a type of additive manufacturing technology. Compared with other additive manufacturing technologies that use powder as raw material, wire printing has high material utilization, high deposition efficiency, and low cost, and is suitable for the preparation of medium and large metal structural parts. Metal wire printing technology uses laser or electric arc as a heat source to melt the substrate to form a molten pool. The metal wire enters the molten pool, solidifies and cools, and the deposition is completed. The metal printing process is accompanied by the accumulation of heat, and usually requires a stop between passes or layers for natural cooling. Subsequent deposition is carried out after the temperature drops to the required level, which reduces production efficiency. The utility model proposes a metal wire printing auxiliary cooling device, which places the additive substrate on a heat sink connected to a water tank, and adjusts the heat dissipation capacity by controlling the speed of the water tank fan and the flow rate of the water, thereby greatly reducing the cooling time and improving the molding efficiency.

[0003] After investigation, the patent number CN202223065476.2 discloses an arc additive manufacturing cooling auxiliary device, which relates to the field of arc additive manufacturing. It solves the problem that the cooling process will consume a lot of time. The utility model is composed of a constant temperature water tank, a water pipe, a water pressure adjustment device, a universal water pipe, a fixed buckle and a water recovery device. The universal water pipe is connected to the welding gun of the welding robot through a buckle and a fixed pipe. The end of the universal water pipe is connected to the outlet pipe. The water pressure adjustment device draws water from the constant temperature water tank through the water inlet pipe, and the water is discharged through the outlet pipe after adjusting to a certain pressure. There is a temperature sensor in the constant temperature water tank, which can monitor, feedback and adjust the temperature of the water in real time. The utility model uses liquid cooling instead of natural cooling, greatly reducing the time required for the cooling of the weld, and improving the printing efficiency, but the structure is complex, the operation is difficult, and the cost is high. Summary of the invention

[0004] The utility model aims to solve the problems of the prior art and proposes a cooling device for quickly cooling deposited metal when printing with wire metal, which has the characteristics of simple structure, convenient operation and low cost.

[0006] Further improvement: the water pipe assembly comprises a water inlet pipe and a water outlet pipe, and the upper ends of the water inlet pipe and the water outlet pipe are respectively fixedly connected to the water inlet and the water outlet of the cooling channel.

[0007] Further improvement: One end of the water tank assembly is provided with a water outlet interface and a water inlet interface which are fixedly connected to the lower ends of the water inlet pipe and the water outlet pipe respectively.

The input of the controller is connected to the temperature measuring assembly, and the output of the controller is connected to the fan and the water pump, and the wind speed and flow rate are automatically adjusted according to the water temperature.
