Problems solved by technology

However, the metal 3D printer needs to be pre-filled with inert gas when it is working, so the working cabin door cannot be opened, and the wind field in the working chamber cannot be detected through the equipment.
[0003] CN109307582A discloses a wind field testing device and testing method for additive manufacturing equipment, including a simulation box, the shape of the simulation box is the same as the box structure of the tested additive manufacturing equipment, a simulated air inlet is opened on the side of the simulation box, and a simulated air inlet is opened on the opposite side. There is a simulated air outlet corresponding to the simulated air inlet, and a measurement component is installed on the top of the simulation box; the test method is to move the measurement component, record the data of the anemometer, and compare the data to draw conclusions; Simulated inspection, but it is still impossible to carry out wind field inspection on the debugged additive manufacturing equipment

Abstract

The invention discloses a wind field detection device for additional material manufacturing equipment. A first guide rail and a second guide rail are included. The first guide rail is provided with asliding block. The second guide rail is vertically in sliding connection to the first guide rail through the sliding block. The sliding block is provided with four first idlers arranged in a rectanglemanner. First motors are arranged at the two ends of the first guide rail. The output ends of the two first motors are connected with belt wheels. A second idler is arranged at one end of the secondguide rail, a second motor is arranged at the other end, a belt fixing pile is arranged at the position close to the second motor, the output end of the second motor is connected with a winding wheel,and the winding wheel is connected with an anemograph through a winding wire. One belt surrounds the two belt wheels, the first idlers, the second idler and the belt fixing pile and is arranged in across-shaped manner. Meanwhile, the invention further discloses the additional material manufacturing equipment applying the wind field detection device. Through control of the first motors and the second motor, three-dimensional monitoring of a work cavity in the additional material manufacturing equipment can be achieved.

Description

technical field [0001] The present invention relates to the field of additive manufacturing, in particular to a wind field detection device for additive manufacturing equipment and an additive manufacturing equipment using the wind field detection device. Background technique [0002] Additive manufacturing is 3D printing technology. In the context of Industry 4.0, the development of additive manufacturing technology has become an inevitable trend. During the printing process of additive manufacturing equipment, the metal powder layer is first spread on the working platform by the powder spreading vehicle, and then the laser is controlled to move in the working platform and sintered; the laser sintering powder process will generate black smoke and splashed powder particles, which will Reduce the printing quality. At this time, the air inlet and outlet are opened, and a layer of wind area is formed above the working platform to discharge black smoke and flying dust particles....
