TW201736090A - Lamination production processing machine to stack up more than two deposition layers on the carrying stage into the lamination body for the molten metal fluid to be solidified into the deposition layer quickly without sagging - Google Patents

Abstract

A lamination production processing machine is disclosed, which comprises a carrying stage and a lamination production device. The lamination production device comprises a material supplying unit for transporting powder to a location above the carrying stage, and a fusion unit for melting said powder into a deposition layer. The fusion unit has: a working air path set for transporting inert gas; a chamber for merging the inert gas and powder, and then releasing powder relative to the carrying stage; and a fusion gun to generate the transfer-type plasma arc effect with the carrying stage. The said transfer-type plasma arc effect is generated at a voltage of greater than 30V, and is applied for melting the powder released from the chamber, so more than two deposition layers can be stacked up on the carrying stage into the lamination body. Accordingly, when melting the powder released from the chamber, heat can be concentrated at the jetted powder, but not at the currently existing deposition layers or workpiece, so the molten metal fluid can be solidified into the deposition layer quickly without sagging.

Description

Laminated manufacturing machine

The present invention relates to a method of manufacturing a laminate, and more particularly to a laminate manufacturing machine.

Referring to Fig. 1, a printing apparatus 1 disclosed in the Patent No. M498668 of the Republic of China, mainly comprises a forming platform 11 carrying a workpiece, a spreading mechanism 12 for spraying powder against the forming platform 11, and a laser. Mechanism 13, and a forging mechanism 14. The laser mechanism 13 is for melting the powder to form a sintered body. The forging mechanism 14 is used for forging the sintered body to make the sintered body structure more compact.

However, the above-mentioned method of forging easily damages the sintered body or deforms the sintered body, and since the sintered body is formed by stacking a plurality of deposited layers, each time a layer of deposited layer is formed, a forged nail is applied, and a process is performed. The shortcomings of time extension.

Accordingly, it is an object of the present invention to provide a laminated manufacturing machine capable of improving the solidity between layers and reducing the processing time.

Thus, the laminated manufacturing machine of the present invention is suitable for producing a laminated body comprising a stage and a laminated manufacturing apparatus.

The laminate manufacturing apparatus includes a material supply unit for conveying powder to the top of the stage, and a melting unit for melting the powder into a deposited layer, the melting unit having a working gas path group for conveying an inert gas a cavity for collecting inert gas and powder and releasing powder relative to the stage, and a melting gun for generating a shifting plasma arc effect with the stage, the shifting plasma arc effect is greater than It is produced at a voltage of 30 volts and is used to melt the powder released from the cavity, so that two or more deposited layers are stacked on the stage as the laminate.

The effect of the invention is that when the powder released from the cavity is melted, the heat can be concentrated on the sprayed powder instead of the existing deposited layer or workpiece, so that the molten metal can be quickly solidified into a sink. Laminated without sagging.

Referring to Fig. 2, an embodiment of the laminated manufacturing machine of the present invention comprises a body 2, a stage 3, a laminated manufacturing apparatus 4, and a driving unit 6.

The stage 3 has a swinging portion 31 pivotally mounted to the body 2, and a carrier portion 32 disposed on the swinging portion 31.

The laminate manufacturing apparatus 4 includes a material supply unit 41 for conveying powder to the load-bearing portion 32 of the stage 3, and a melting unit 42 for melting the powder into a deposition layer 71. The melting unit 42 is a shifting plasma arc apparatus in the present embodiment, and has a working gas path group 421 for conveying an inert gas, and a bearing portion 32 for collecting inert gas and powder and opposing the stage 3. A cavity 422 for discharging the powder, and a melting gun 423 which generates an arc effect with the carrier portion 32 of the stage 3. The aforementioned shifting plasma arc effect is for melting the powder released from the cavity 22, causing the molten powder to fall on the stage 3 to form a deposited layer, and stacking the deposited layers 71 of the two or more layers. The stage 3 is formed on the laminated body 7.

The driving device 6 includes a first driving unit 61 that drives the melting unit 42 to be displaced in an X-axis direction and a Y-axis direction, and a second driving unit 62 that drives the melting unit 42 to be displaced in a Z-axis direction, respectively. a third driving unit 63 that drives the swinging portion 31 of the stage 3 to rotate around the X-axis, and a fourth driving unit 64 that drives the carrying portion 32 of the stage 3 to rotate around the Z-axis .

During processing, the first driving unit 61, the second driving unit 62, the third driving unit 63 and the fourth driving unit 64 are controlled, so that the melting unit 42 can follow the X-axis direction and the Y-axis. The direction, the displacement in the Z-axis direction, and the swinging portion 31 of the stage 3 are rotated about the X-axis, and the carrier portion 32 of the stage 3 is rotated about the Z-axis. Scanning and filling is performed on the carrying portion 32, and a plurality of deposited layers 71 are stacked to form a laminated body 7, or a workpiece (not shown) is disposed on the carrying portion 32, and a joint with the workpiece is formed on the workpiece. Laminated body 7.

It should be noted that the shifting plasma arc effect of the melting unit 42 is generated at a voltage greater than 30 volts and does not cause a keyhole phenomenon, and therefore, when melting the powder released from the cavity 22, it can be made The heat is concentrated on the sprayed powder instead of the existing deposited layer 71 or workpiece (not shown), whereby the molten molten metal can be rapidly solidified into the deposited layer 71 without sagging.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

When the powder released from the cavity 422 is melted, the present invention can concentrate the heat on the sprayed powder instead of the existing deposited layer 71 or the workpiece, so that the molten molten metal can be rapidly solidified into the deposited layer 71. Without sag, the melting unit 42 using the shifting plasma arc device is lower in cost, and for the finished product with lower precision requirements, the compactness and appearance of the laminated body 7 can also meet the process requirements.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
