Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
The Arc fuse additive manufacturing device provided by the embodiment of the invention is suitable for various Arc fuse additive manufacturing heat sources, such as an Arc heat source in a Metal Arc Welding (MIG) process or a Cold Metal Transfer (CMT) process, or a Plasma Arc heat source in a Gas Arc Welding (TIG) process or a Plasma Arc Welding (PAW) process, and is used for additive manufacturing with high forming efficiency.
Fig. 1 is a schematic structural diagram of an arc fuse additive manufacturing apparatus according to an embodiment of the present invention, as shown in fig. 1, the arc fuse additive manufacturing apparatus includes: a control unit 10, an electric heating unit 20, a welding wire 30, an arc striking unit 40, and an electric base plate 50; the electric heating unit 20 is arranged above the electric substrate 50, and the distance between the electric heating unit 20 and the electric substrate 50 is an arc striking distance L;
the control unit 10 is electrically connected with the welding wire 30 and the arc striking unit 40 respectively, and is used for controlling the welding wire 30 to move between the electric heating unit 20 and the electric base plate 50 during area printing for fuse additive manufacturing; and controlling the arc-striking unit 40 to move to be disposed opposite to the electric heating unit 20 at the end of the area printing for guiding the heat source between the electric heating unit 20 and the electric substrate 50 to between the electric heating unit 20 and the arc-striking unit 40.
In particular, the arc fuse additive manufacturing technology is particularly suitable for the additive manufacturing of difficult-to-machine and precious metal parts due to the characteristics of the heat source used and the feeding mode of the material. Here, there are two main forms of the arc fuse additive manufacturing technology, one is a coaxial wire feeding form based on consumable electrode arc, that is, the metal wire is fused on the electric substrate 50 by using the arc as a heat source to be deposited and formed layer by layer; the other is a plasma arc-based paraxial wire feeding mode, namely, the plasma arc is used as a heat source to melt metal wires and deposit and form the metal wires layer by layer, and a three-dimensional metal blank which is close to the shape and the size requirements of a product is manufactured on the electric substrate 50. The distance between the two electrodes when the arc fuse is manufactured in an additive mode needs to be set as an arc striking distance L. The specific value of the arc striking distance L is mainly determined by the nature of the heat source technology of the arc fuse additive manufacturing. Under a specific heat source technology, no matter the distance between the two electrodes is smaller than the arc striking distance L or larger than the arc striking distance L, air cannot be punctured to generate a heat source, namely, an electric arc or a plasma arc cannot be generated, the heat source is excited only when the distance is equal to or very close to the arc striking distance, and after the heat source is generated, source fuse materials such as a welding wire 30 and the like are required to be continuously printed in the heat source to maintain the arc extinction of the heat source.
When the additive manufacturing is started, the electric base plate 50 is connected with the negative electrode of the power supply, the electric heating unit 20 is connected with the positive electrode of the power supply, the control unit 10 controls the welding wire 30 to move between the electric heating unit 20 and the electric base plate 50, when the distance between the electric base plate 50 and the welding wire 30 or the distance between the electric base plate 50 and the electric heating unit 20 is equal to or close to the arc starting distance L, air in the arc starting distance L is broken down to generate an electric arc or a plasma arc, and the electric arc or the plasma arc serves as a heat source to melt the welding wire 30 on the electric base plate 50 to be deposited and formed layer by layer, so that area printing is realized. At the moment when the area printing is finished, the control unit 10 controls the arc striking unit 40 to move to be disposed opposite to the electric heating unit 20, and does not extinguish the arc to the arc striking unit 40 from the welding wire 30 or the heat source between the electric heating unit 20 and the electric substrate 50. The control unit 10 then controls the arc-starting unit 40, the welding wire 30 and/or the electric heating unit 20 to move together to the starting point of the new area printing, so as to drive the heat source on the arc-starting unit 40 to move to the starting point of the new area printing without quenching the arc. Finally, the control unit 10 controls the welding wire 30 and/or the electric heating unit 20 to drive the heat source to move out of the arc striking unit 40 without quenching the arc and start printing at the starting point of the new area printing. Therefore, the arc striking unit 40 completes the arc striking process of not extinguishing the arc from the moment when the zone printing is finished to the starting point of the new zone printing under the control of the control unit 10, and the printing efficiency of the additive manufacturing is greatly improved. In the arc striking process, the arc striking unit 40 can be connected to a power supply cathode, and the arc striking unit 40 can be made of materials of the electric substrate 50, so that the arc striking unit 40 can play a role of the electric substrate 50 and a role of the welding wire 30 to ensure that the heat source is generated and maintained and is not extinguished, the arc striking function is further exerted, the arc striking is not extinguished between non-communicated areas under the condition that the electric substrate 50 is not moved, and the forming efficiency of the arc fuse additive manufacturing is improved.
Illustratively, as shown in fig. 1, when additive manufacturing is started, the control unit 10 controls the welding wire 30 to melt in the area corresponding to the blank S1 to deposit layer by layer to form the blank S1, when the printing of the blank S1 is finished, the control unit 10 controls the arc ignition unit 40 to perform arc ignition, and without arc quenching, the arc ignition unit 40, the welding wire 30 and/or the electric heating unit 20 are moved together to the printing starting point of the area corresponding to the blank S2, and the blank S2 is printed. Alternatively, when the blank W is printed, since the blank W includes the disconnected regions W1 and W2. In the additive manufacturing process, the area W1 is firstly subjected to layer-by-layer deposition printing, when the area W1 is printed, the control unit 10 controls the arc striking unit 40 to strike an arc, and under the condition that the arc is not extinguished, the movable arc striking unit 40, the welding wire 30 and/or the electric heating unit 20 move together to the area W2, and the area W2 is subjected to layer-by-layer deposition printing.
The arc fuse wire additive manufacturing device provided by the embodiment of the invention has the advantages that by arranging the arc striking unit, when the area printing is finished, the arc striking unit is utilized to guide the heat source from the position where the area printing is finished to the starting point of the new area printing, the arc striking unit plays the role of the electric substrate and the welding wire in the arc striking process, the generation and the maintenance of the heat source are ensured, the arc extinguishing of the heat source is avoided, the multiple arc striking and arc extinguishing of the heat source in the traditional process of printing non-connected areas between layers and each layer or multiple parts on the same substrate are avoided, the time cost caused by the multiple arc striking and arc extinguishing is reduced, the non-arc extinguishing of the heat source at the non-connection position of the path between the layers and each layer or in the process of printing multiple parts on the same substrate is realized, the freedom degree of forming path planning is improved, and the forming efficiency of the arc fuse wire additive manufacturing is also improved, the applicability of the arc fuse additive manufacturing to batch printing is expanded.
Optionally, the arc ignition unit 40 comprises an arc ignition plate; the material of the arc ignition plate is the same as that of the electric substrate 50. Specifically, since the arc striking plate needs to serve as the electric substrate 50 to ensure the heat source to occur during the arc striking process, the arc striking plate and the electric substrate 50 can be made of the same material or materials with the same properties; moreover, during the arc striking process, the arc striking plate may also serve as a role of the welding wire 30 to maintain a heat source, and therefore, the arc striking plate, the electric substrate 50 and the welding wire 30 may all be made of the same material or materials with the same property; the material of the welding wire 30 can be metal, steel-aluminum alloy, titanium alloy, high temperature alloy, etc.
Example two
In this embodiment, the first embodiment is further refined, and fig. 2 is a schematic structural diagram of an arc fuse additive manufacturing apparatus according to a second embodiment of the present invention during area printing, as shown in fig. 2, optionally, the electric heating unit 20 is disposed around the welding wire 30 along a direction parallel to the surface of the electric substrate 50; the bonding wire 30 moves in a direction perpendicular to the surface of the electrical substrate 50.
Specifically, when the electric heating unit 20 includes a consumable arc welding process or a cold metal transfer welding process, the welding wire 30 is electrically connected with the control unit 10, and the welding wire 30 serves as an electrode, the electric heating unit 20 may be disposed around the welding wire 30, and the electric heating unit 20 and the welding wire 30 may be coaxially controlled by the control unit 10. The welding wire 30 is drawn up and down along the direction vertical to the surface of the electric base plate 50, so that short circuit and open circuit are ensured to occur when the arc striking distance L is reached between the welding wire 30 and the electric base plate 50, air is broken down in the arc striking distance L to generate electric arc, and meanwhile, the welding wire 30 is melted on the electric base plate 50 by the electric arc, so that a blank is formed in a printing area. The arc striking plate 40 is electrically connected to the control unit 10, and at the moment of finishing the area printing, the control unit 10 controls the arc striking plate 40 to move to a position opposite to the electric heating unit 20 and the welding wire 30, so as to guide the arc between the electric heating unit 20 and the welding wire 30 and the electric substrate 50 to the electric heating unit 20 and between the welding wire 30 and the arc striking plate 40. The arc striking plate 40 moves to the start point of the new printing area opposite to and together with the electric heating unit 20 and the welding wire 30 under the control of the control unit 10, so that the arc between itself and the electric heating unit 20 and the welding wire 30 is not extinguished to be led to the start point of the new printing area. In the process of moving to the printing starting point of the new area relatively and together, the electric heating unit 20 and the welding wire 30 are kept at the arc striking distance L from the arc striking plate 40, the welding wire 30 is printed on the arc striking plate 40, and the arc striking plate 40 plays the role of an electric substrate 50, and is used as an electrode and a fuse for receiving the welding wire 40, so that the electric arc is not extinguished from the moment when the area printing is finished to the printing starting point of the new area under the condition that the electric substrate 50 is not moved in place.
With continued reference to fig. 2, optionally, an arc runner 40 is disposed on one side of the electric heating unit 20 in the direction of the arrangement of the zones; the arc ignition plate 40 and the electric substrate 50 form an included angle A, one side of the arc ignition plate 40 close to the electric heating unit 20 is lower than one side of the arc ignition plate 40 far away from the electric heating unit 20, and the lowest point of the arc ignition plate 40 and the end position of the area printing are in the same horizontal plane.
Specifically, at the moment of finishing the area printing, fig. 3 is a schematic structural diagram of an arc fuse additive manufacturing apparatus according to a second embodiment of the present invention during arc striking, as shown in fig. 3, the control unit 10 controls the arc striking plate 40 to move to a position opposite to the electric heating unit 20 and the welding wire 30, so as to guide the arc between the electric heating unit 20 and the welding wire 30 and the electric substrate 50 to the electric heating unit 20 and between the welding wire 30 and the arc striking plate 40. In order to prevent the arc from being extinguished at the moment when the arc is introduced onto the arc ignition plate 40 from the end position of the area printing, the arc ignition plate 40 may be disposed on one side of the electric heating unit 20 and close to the electric heating unit 20, and the lowest point of the arc ignition plate 40 is in the same horizontal plane as the end position of the area printing, so as to prevent the arc from being extinguished when the arc is introduced onto the arc ignition plate 40 from the end position of the area printing, and the distance between the electric heating unit 20 and the welding wire 30 and the electric substrate 50 does not reach the arc initiation distance L.
After the arc is initiated, fig. 4 is a schematic structural diagram of an arc fuse additive manufacturing apparatus according to a second embodiment of the present invention when the arc initiation plate 40, the electric heating unit 20 and the welding wire 30 are moved to a new area printing initiation point by the control unit 10, as shown in fig. 4, the electric heating unit 20 and the welding wire 30 are controlled by the control unit 10 to move out of the arc initiation plate 40 to the new area printing initiation point together with the arc, and the printing is started.
With continued reference to fig. 4, optionally, the angle of the arc runner 40 is 0 ° or more and 45 ° or less.
Specifically, at the moment when the arc is not extinguished from the end position of the area printing to be introduced onto the arc ignition plate 40 and after being introduced onto the arc ignition plate 40, the welding wire 40 is continuously drawn back and forth and melted onto the arc ignition plate 40 by the arc, and the accumulated fuse is deposited on the arc ignition plate 40 at a position close to the included angle a. By arranging the arc striking plate 40 obliquely, arc blowout due to the distance between the electric heating unit 20 and the welding wire 30 and the electric substrate 50 or the distance between the electric heating unit 20 and the welding wire 30 and the arc striking plate 40 not reaching the arc striking distance L can be avoided.
In addition, when the inclination angle a of the arc ignition plate 40 is zero degree, it is only applicable to the thickness of the fuse deposited on the arc ignition plate 40 by the bonding wire 30 is negligible. As the control unit 10 controls the starting point of the arc starting plate 40, the electric heating unit 20 and the welding wire 30 to print to the new area to move, and the welding wire 30 is continuously melted on the arc starting plate 40, the inclination angle a of the arc starting plate 40 can be increased to avoid that the fuse wire on the arc starting plate 40 cannot be affected, and when the arc moves from the arc starting plate 40 to the starting point of the new area to print, the distance between the arc and the electric substrate 50 cannot reach the arc starting distance L. If the angle of inclination a of the arc ignition plate is too large, for example, greater than 45 degrees, the fuse droplet of the bonding wire 30 will slide along the arc ignition plate 40 onto the electric substrate 50, which will affect the overall formation of the final blank, preferably, the angle of inclination is 25 degrees or 30 degrees. In addition, before next arc striking, the arc striking plate 40 deposited with the fuse can be milled for recycling, and before next arc striking, the arc striking plate 40 can be replaced to improve the arc striking quality.
Optionally, fig. 5 is a schematic view of the arc starting plate rotating horizontally with respect to the electric heating unit and the welding wire with an inclination angle as a center according to the embodiment of the present invention, as shown in fig. 5, in the process that the control unit 10 controls the arc starting plate 40, the electric heating unit 20 and the welding wire 30 to move to the starting point of the new area printing, the arc starting plate 40 may be controlled to rotate horizontally with respect to the electric heating unit 20 and the welding wire 30 with the inclination angle a as a center, so as to avoid fuse deposition on the arc starting plate 40; the adjustment of the inclination angle a and the control of the horizontal rotation of the arc runner 40 with respect to the electric heating unit 20 and the welding wire 30 about the inclination angle a may be simultaneously performed to prevent the accumulation of the fuse deposited on the arc runner 40.
Optionally, the control unit 10 controls the electric heating unit 20 and the welding wire 30 to move relative to the arc ignition plate 40 above the arc ignition plate 40 coaxially in the process of controlling the movement of the arc ignition plate 40, the electric heating unit 20 and the welding wire 30 to the starting point of the new area printing, and in addition to keeping an arc ignition distance L between the electric heating unit 20 and the arc ignition plate 40 and between the welding wire 30 and the arc ignition plate 40, the movement of the electric heating unit 20 and the welding wire 30 relative to the arc ignition plate 40 is a circular movement, so as to avoid fuse deposition on the arc ignition plate 40, and further avoid arc extinction caused by the fact that the distance between the electric heating unit 20 and the welding wire 30 and the arc ignition plate 40 does not reach the arc ignition distance L. Fig. 6 shows a circular motion track of the electric heating unit and the welding wire relative to the arc plate according to the embodiment of the present invention, and fig. 7 shows another circular motion track of the electric heating unit and the welding wire relative to the arc plate according to the embodiment of the present invention, as shown in fig. 6 and 7, such circular motion tracks may be formed by depositing the welding wire 30 on the arc plate in a "C" shape or a "back" shape, so that the arc striking distance L between the electric heating unit 20 and the welding wire 30 and the arc plate 40 is ensured, and arc blowout is avoided.
Optionally, the thickness of the arc striking plate 40 is 2-10 mm. Specifically, the arc striking plate 40 has a characteristic of striking the arc without quenching the arc, and the thickness thereof should be smaller than the arc column height of the arc, and therefore, the thickness of the arc striking plate 40 is preferably 2 to 10 mm. In addition, since the arc striking plate 40 needs to receive the fuse of the welding wire 30 during the process of striking the arc, the arc striking plate 40 has a certain area.
According to the arc fuse additive manufacturing device provided by the embodiment of the invention, the welding wire is used as an electrode, the electric heating unit is arranged around the welding wire, an electric arc is generated between the welding wire and the electric substrate, and the electric arc is used as a heat source to melt the welding wire on the electric substrate to be deposited and formed layer by layer. When the area printing is finished, the arc striking plate is controlled to move to the side of the electric heating unit and the welding wire, the electric arc is moved to the arc striking plate, then the arc striking plate, the electric heating unit and the welding wire are controlled to move to the initial point of the new area printing together, and therefore under the condition that the electric substrate is not moved, the electric arc is not extinguished to be led to the initial point of the new area printing through the arc striking plate, multiple times of arc striking and arc extinguishing in the process from the area printing to the new area printing in the prior art are avoided, arc fuses are not extinguished in the process of manufacturing non-connected positions of paths between printing layers, non-connected areas of each layer or multiple parts on the same substrate in an additive manufacturing mode, the degree of freedom of forming path planning is improved, the forming efficiency of the arc fuse additive manufacturing is also improved, and the applicability of the arc fuse additive manufacturing to batch printing is expanded.
