Description

Technical Field

[0001] The invention relates to the technical field of industrial design, and in particular to a device for trimming the appearance of an industrial design product. Background Art

[0002] At present, various industrial processing products we use not only need to have corresponding product functions, but also need to have a certain appearance design to meet the convenience of use or visual aesthetics. Industrial design often requires designing and adjusting the product appearance during the design stage. Generally, a virtual model will be established in the computer to roughly determine the design direction, and then a clay model will be made in reality for detailed adjustment.

[0003] Clay is a material with a certain hardness and good machinability at room temperature, and a certain plasticity under a certain high temperature or external force. In industrial design, clay is first used to make a clay sculpture with the general outline of the product, and then a CNC robot arm and a rotary cutting tool are used to cut its surface for preliminary shaping. The designer then manually carves the clay model or applies new clay to the surface of the model to make detailed adjustments to the product contour lines. A large amount of clay debris will be generated during the cutting process. After the cutting work is completed, the clay debris at the work site needs to be recycled and reprocessed into clay columns or clay blocks for subsequent use. The recycling process requires interrupting the modeling operation, which has a certain impact on work efficiency. At the same time, the CNC robot arm can only perform cutting work. When the appearance of the model needs to be adjusted by additive manufacturing, it can only be applied manually. When the clay temperature is low, its plasticity is slightly poor, and manual application is relatively laborious, which will also reduce work efficiency. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] Combined with Figure 1 , Attachment Figure 2 and attached Figure 4 A device for trimming the appearance of an industrial design product comprises a cylindrical shell 1, a connecting tool 7, an air-electric integrated slip ring 8 and a vortex tube 30, wherein the connecting tool 7 is arranged on one side of the outer side of the cylindrical shell 1, and the air-electric integrated slip ring 8 is arranged on the side of the connecting tool 7, wherein the rotor end of the air-electric integrated slip ring 8 is fixedly connected to the connecting tool 7, and the stator end is respectively connected with a second suction pipe 11 and a second compressed air pipe 13, and an air suction hood 18 is arranged on one side of the inner side of the cylindrical shell 1, and the air suction hood 18 is sleeved with the vortex tube 30.

[0032] The above-mentioned gas-electric integrated slip ring 8 is a prior art and will not be further described in this application. When the present invention is implemented, the gas-electric integrated slip ring 8 should be a model with at least two gas paths.

[0033] Combined with Figure 7 and attached Figure 8A hot air pipe 31 is arranged at one end of the vortex tube 30, and a cold air pipe 10 is arranged at the other end. One end of the cold air pipe 10 passes through the cold end cover 2 and is connected to the outside, and is extended to the root of the hot air pipe 31 and is provided with an isolation ring 32. A compressed air channel 33 is arranged inside the air suction hood 18 and is tangentially connected to the side wall of the vortex tube 30. A first compressed air pipe 14 is arranged outside the cylindrical shell 1 and is connected to the compressed air channel 33. The end of the first compressed air pipe 14 is connected to one of the gas paths of the gas-electric integrated slip ring 8. A screw 19 is rotatably sleeved at the hot gas outlet end of the vortex tube 30. A hot end cover 3 is arranged at one end of the cylindrical shell 1. A hot gas outlet 24 is arranged in the center of the hot end cover 3. A counterflow cone 25 is arranged in the center of the hot gas outlet 24. The central axis of the screw 19 is arranged to be hollow, and the hot gas outlet 24 is connected to the inside of the central axis of the screw 19.

[0034] The above components constitute the air path structure of the vortex tube 30, which is connected to the external air compressor through the second compressed air pipe 13, and the compressed air is passed into the vortex tube 30. The compressed air enters the interior of the vortex tube 30 in the tangential direction of the contour of the vortex tube 30 to generate a rotating vortex, and is guided by the isolation ring 32 into the hot air pipe 31. Here, the vortex airflow undergoes internal heat exchange, wherein the hot air vortex and the screw 19 are avoided from being squeezed out, and part of the heat is transferred to the screw 19, and finally discharged through the gap between the hot air outlet 24 and the reflow cone 25. The cold air vortex is blocked by the reflow cone 25 and flows into the cold air pipe 10 and is discharged through the cold air pipe 10.

[0035] Combined with Figure 5 The other side wall of the cylindrical shell 1 connected to the connecting tool 7 is provided with a sludge recovery port 17 connected to the interior, and a sludge outlet 20 is provided near the hot end cover 3 on the same side where the cylindrical shell 1 is connected to the connecting tool 7. A sludge extrusion chamber 6 is provided outside the cylindrical shell 1 and is connected to the inside of the cylindrical shell 1 through the sludge outlet 20. An isolating cylinder 21 is rotatably sleeved inside the cylindrical shell 1, and the isolating cylinder 21 is located between the screw 19 and the inner wall of the cylindrical shell 1. A first connecting port 22 matching the sludge recovery port 17 and a second connecting port 23 matching the sludge outlet 20 are provided in the middle of one side of the isolating cylinder 21. A cold end cover 2 is provided at the other end of the cylindrical shell 1 where the hot end cover 3 is provided, and a transmission mechanism for driving the screw 19 and the isolating cylinder 21 to rotate is provided inside the cold end cover 2 of the cylindrical shell 1.

[0036] The isolation cylinder 21 is rotated to align the sludge recovery port 17 with the first connecting port 22. This state is the sludge debris recovery state. The suction hood 18 is used to suck the inside of the cylindrical shell 1 to form a negative pressure. The sludge recovery port 17 is brought close to the sludge debris to suck it into the cylindrical shell 1. After the recovery is completed, the isolation cylinder 21 is rotated again to change the position of the first connecting port 22, so that the isolation cylinder 21 isolates the sludge recovery port 17 from the inside of the cylindrical shell 1 and stores the sludge debris in the cylindrical shell 1.

[0037] The isolating cylinder 21 is rotated to align the sludge outlet 20 with the second connecting port 23. This state is the sludge extrusion state. The screw 19 is heated by the vortex of hot gas from the rotating vortex tube 30. The sludge debris in the cylindrical shell 1 is heated and softened, while the sludge is squeezed into the sludge extrusion chamber 6 in the form of screw conveying and extruded. The sludge can be squeezed onto the surface of the sludge model for subsequent modeling treatment, or it can be squeezed into a sludge recovery and shaping container for recovery.

[0038] Combined with Figure 2 and attached Figure 6 The root of the screw 19 extends into the air suction hood 18 and is fixedly connected to a first gear ring 26. A first gear 28 is rotatably arranged in the air suction hood 18 and meshes with the first gear ring 26. A first motor 15 is arranged outside the cold end cover 2 and is power-connected to the first gear 28. The root of the isolation cylinder 21 extends into the air suction hood 18 and is fixedly connected to a second gear ring 27. A second gear 29 is rotatably arranged in the air suction hood 18 and meshes with the second gear ring 27. A second motor 16 is arranged outside the cold end cover 2 and is power-connected to the second gear 29.

[0039] The screw 19 can be driven to rotate by the first motor 15 , and the isolation cylinder 21 can be driven to rotate by the second motor 16 .

[0040] Combined with Figure 2 and attached Fig. 9 An air suction chamber 34 and an air suction channel 36 connected to the air suction chamber 34 are provided inside the air suction hood 18. A filter net 35 is provided on the surface of the air suction hood 18 to connect the air suction chamber 34 with the inside of the cylindrical shell 1. A first suction pipe 12 is provided outside the cylindrical shell 1 to connect with the air suction channel 36. The end of the first suction pipe 12 is connected to one of the air paths of the gas-electric integrated slip ring 8.

[0041] The second suction pipe 11 is connected to the air inlet end of an external air compressor or a vacuum pump, and suctions the inside of the cylindrical shell 1 through the suction chamber 34. The airflow drives the oily sludge debris into the cylindrical shell 1 under the pressure difference between the inside and outside of the cylindrical shell 1. The oily sludge debris is isolated by the filter 35, and the air passes through the filter and enters the suction chamber 34.

[0042] Combined with Figure 3 A three-way valve 4 is provided outside the hot end cover 3 and is connected to the hot air outlet 24 . The three-way valve 4 is connected to the first hot air pipe 5 and the second hot air pipe 37 .

[0043] The outlet of the first hot air pipe 5 is coaxially arranged with the cylindrical shell 1, and the outlet of the second hot air pipe 37 is led to other directions. When the plasticizing clay model needs to be heated and softened, the three-way valve 4 can be controlled to allow the first hot air pipe 5 to discharge hot air flow to blow and heat the clay model, and in other states, it is discharged through the second hot air pipe 37. In addition, when the clay model needs to be cooled and shaped, the cold air flow discharged from the cold air pipe 10 can be blown to cool the clay model.

[0044] The end of the oil mud extrusion chamber 6 is sleeved with an extrusion molding port 38 . By connecting the extrusion molding ports 38 with different outlet shapes, the cross-sectional shape of the oil mud during extrusion can be changed to create special molding lines.

[0045] Combined with Figure 2 and attached Figure 3 The stator end of the gas-electric integrated slip ring 8 is provided with a third motor 9, one side of the shell of the third motor 9 is fixedly connected to the stator end of the gas-electric integrated slip ring 8, and the other end is connected to an external CNC robot arm. The axis of the output end of the third motor 9 is perpendicular to the axis of the cylindrical shell 1 and is dynamically connected to the connecting tooling 7.

[0046] The cylindrical shell 1 is rotated as a whole by the third motor 9 to change the positions of the first hot air pipe 5 , the cold air pipe 10 and the extrusion molding port 38 .

[0047] The present invention and its implementation methods are described above, and such description is not restrictive, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by it, and does not deviate from the purpose of the invention, and does not creatively design a structure and implementation method similar to the technical solution, they should all fall within the protection scope of the present invention.
