Local gas sealing device for additive and subtractive manufacturing

Abstract

A local gas sealing device for additive and subtractive manufacturing relates to the technical field of additive manufacturing sealing equipment and comprises a fixed box, the fixed box is fixedly connected to a machine tool slide carriage, a movable laser cladding head and a welding gun are arranged in the fixed box, an upper sealing cover is fixedly connected to the opening side of the fixed box, the upper sealing cover is fixedly connected with a lower sealing cover through a flexible sealing cover with a bidirectional opening, and the edge of the bottom of the lower sealing cover is provided with a sealing air bag which can deform towards the inner side and is matched with an embedded groove in a machine tool workbench. According to the local gas sealing device for additive and subtractive manufacturing, only a machining area is locally sealed, the use amount of protective gas is reduced, and the preparation time in the inflation and deflation stage is saved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing sealing equipment, in particular to a local gas sealing device for additive and subtractive material manufacturing. Background technique [0002] In actual production and scientific experiments, when additive manufacturing or welding technology processes special materials and complex parts, in order to ensure the quality of the workpiece, it is necessary to perform a reliable sealing operation on the surrounding space to achieve the gas requirements in the processing area. The traditional automatic continuous operation Machine tools generally adopt an integral seal, that is, the transmission system of the machine tool and the processing system are sealed together. The traditional seal requires a large amount of gas each time, which is a waste of time. The manufacture of traditional seals requires a large amount of materials, and some parts that do not need to be sealed are also used....

Problems solved by technology

[0002] In actual production and scientific experiments, when additive manufacturing or welding technology processes special materials and complex parts, in order to ensure the quality of the workpiece, it is necessary to perform a reliable sealing operation on the surrounding space to achieve the gas requirements in the processing area. The traditional automatic continuous operation Machine tools generally adopt an integral seal, that is, the transmission system of the machine tool and the processing system are sealed together. The traditional seal requires a large amount of gas every time, which is a waste of time. The manufacture of traditional seals requires a large demand for materials, and some parts that do not need to be sealed are also used. Sealing in it is not conducive to saving costs, and cannot better save processing time. When complex parts need to be processed by adding or subtracting materials, the traditional seal cannot complete one clamping and one positioning, which affects the processing accuracy and quality. The sealing device only seals part of the whole machine tool, and can automatically shrink without breaking the continuity of the machine tool, and can switch any process
