Description

Technical Field

[0001] This invention relates to the field of metal additive manufacturing technology, specifically to a novel three-station integrated laser powder melting additive manufacturing equipment. Background Technology

[0002] Additive manufacturing technology is a manufacturing technique that uses a 3D design model to create a product layer by layer through slicing. Additive manufacturing technology overcomes the structural and performance limitations of tooling and fixtures, greatly increasing design freedom. It also eliminates the prescribed processes of traditional manufacturing methods, saving production time, especially new product development time, and is widely used in many fields.

[0003] However, existing additive manufacturing processes typically require the collaborative use of both additive manufacturing equipment and molding equipment. The molding equipment includes a rolling device and a milling device. After additive manufacturing, the printed material is rolled and then milled to form the final molded part. However, due to the inherent properties of the material during the printing process, porosity issues exist. If the molded part is printed and cooled completely before being rolled and milled, the rolled part can only be rolled on the surface. Since the part has already cooled and is fully printed, the rolling effect on the cooled parts is limited, and the internal porosity cannot be effectively eliminated. The porosity will still remain in the molded part. Therefore, there is an urgent need to design a new three-station integrated laser powder melting additive manufacturing equipment to solve the above problems. Summary of the Invention

[0004] The technical problem this invention aims to solve is: by designing an integrated additive molding equipment, after a certain number of additive printing layers are formed during the entire process, the printed body can be promptly transferred to the forging station for immediate forging by first rolling and then milling. This achieves a cyclical operation of printing-rolling and milling-printing-rolling and milling throughout the entire process. This allows for timely reduction of internal porosity in the molded part through the rolling and milling process during the printing process, increasing the overall density of the molded part and thus improving the quality and performance of the finished molded part after the entire process is completed. At the same time, it can accurately position the printing station or forging station when moving to ensure the accuracy and consistency of the printing and forging processes. A hoisting station is set up to facilitate subsequent hoisting work.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a novel three-station integrated laser powder melting additive manufacturing equipment, comprising: a main body of the equipment, a moving support component for supporting and moving the main body of the molding cylinder and the molding substrate, a printing component for printing on the molding substrate, a forging component for rolling and milling on the molding substrate, and a hoisting assembly component for hoisting the molding substrate together with the molded parts.

[0006] Both the printing component and the forging component are located on the top of the main body of the equipment and are arranged in a straight line. Both the printing component and the forging component have channels that communicate with the outside.

[0007] The mobile support assembly is disposed inside the main body of the equipment. The mobile support assembly includes a molding cylinder housing, a molding cylinder track, and a support drive mechanism. The top of the molding cylinder housing has a housing opening corresponding to the channel. The molding cylinder body is mounted on the molding cylinder housing. The moving end of the molding cylinder body is located inside the molding cylinder housing and is used to drive the molding substrate to move out of or into the housing opening. The molding cylinder track is located in the middle of the main body of the equipment and its extension direction is consistent with the direction of the straight layout. The support drive mechanism is driven to the molding cylinder track and is used to drive the molding cylinder housing to move on the molding cylinder track.

[0008] The hoisting assembly includes a hoisting opening on the top of the main body of the equipment. The hoisting opening is rectangular and is located above the forming cylinder track and on the extension line of the straight layout.

[0009] When the bearing drive mechanism moves the molding cylinder housing to below the printing component, the molding cylinder body moves the molding substrate upward and into the corresponding channel of the printing component, so that the molding substrate is located at the printing station.

[0010] When the bearing drive mechanism moves the forming cylinder housing to below the forging assembly, the forming cylinder body moves the forming substrate upward and into the corresponding channel of the forging assembly, so that the forming substrate is located at the forging station.

[0011] When the bearing drive mechanism moves the molding cylinder housing to below the hoisting assembly, the molding cylinder body moves the molding substrate upward until the molding substrate is located at the hoisting opening, so that the molding substrate is located at the hoisting position.

[0012] During equipment operation, the bearing drive mechanism and the forming cylinder body are operated to move the forming substrate to the printing station, completing the first printing process and obtaining a first printed body. The bearing drive mechanism and the forming cylinder body are then operated again to move the forming substrate to the forging station, completing the first forging process of the first printed body and obtaining a first forged body. Subsequently, the bearing drive mechanism and the forming cylinder body are operated to return the forming substrate to the printing station, completing the second printing process on the first forged body and obtaining a second printed body. The second printed body then enters the forging station for a second forging process and obtains a second forged body. Following this operating mode, and based on the molding requirements, the forming substrate is switched between the printing station and the forging station to complete a cyclical process of printing followed by forging to obtain the final molded part. After obtaining the final molded part, the bearing drive mechanism and the forming cylinder body are operated to move the forming substrate to the hoisting station for hoisting the molded part.

The printing box is disposed on the top of the main body of the equipment. The galvanometer body is disposed on the top plate of the printing box.

[0017] As a preferred embodiment of the present invention, a magnetic scale is provided on the molding cylinder track in the same direction as its extension, and a reading head that cooperates with the magnetic scale is provided on the bearing drive mechanism.

[0018] As a preferred embodiment of the present invention, N positioning telescopic pins are provided on the outer side of the forming cylinder shell, N printing positioning pin holes corresponding to the positioning telescopic pins are provided at the printing opening, and N forging positioning pin holes corresponding to the positioning telescopic pins are provided at the forging opening.

[0021] As a preferred embodiment of the present invention, the hoisting assembly further includes a switchable and airtight door disposed at the hoisting opening.

[0022] The beneficial effects of this invention are reflected in:

[0023] 1. By simultaneously setting up a printing component and a forging component in one device, and cooperating with the forming cylinder track and the load-bearing drive mechanism, the forming cylinder shell can be moved below the printing component and the forging component. Under the action of the forming cylinder body, and with the support of the load-bearing drive mechanism, the forming substrate can be switched between the printing component and the forging component. In the entire process, when at the printing station, after printing a certain number of layers on the forming substrate, the printed body is promptly transferred to the forging station. Subsequently, it undergoes rolling and milling in the forging component, and then is transferred back to the printing component for printing, forming a printing-rolling and milling-printing-rolling and milling cycle. Because the overall printing process reduces the porosity of the material and improves the overall density, the quality and performance of the finished product are improved.

[0024] 2. A magnetic scale and reading head are used for the first positioning. Then, a second positioning is achieved by setting a positioning telescopic pin and cooperating printing positioning pin holes and forging positioning pin holes. This ensures that the positional relationship between the forming cylinder shell and the printing station remains consistent during printing, and the positional relationship between the forming cylinder shell and the forging station remains consistent during forging. This ensures that the positional relationship remains consistent for each printing and forging operation in the printing-forging-printing-forging cycle, thereby ensuring the overall printing and forging quality and effect.

[0025] 3. By setting the printing component, forging component and frame to be connected, and the moving load-bearing component to move inside the frame, the entire printing process is kept in a closed space formed by the frame, printing component and forging component, so that it can be protected by the protective gas supplied in the printing component, ensuring the printing and forging effect.

[0026] 4. By setting up a forming cylinder shell for load transfer, the shell wall can play a heat preservation role during the transfer process, ensuring the forging effect after printing;

[0027] 5. By setting up a hoisting opening in conjunction with a switchable airtight door, the machine can be moved to the hoisting opening after the part has been printed, facilitating subsequent hoisting. The existence of the switchable airtight door ensures that the main body of the equipment is in a relatively sealed state during the printing process, while allowing the hoisting opening to be open during hoisting.

Preferably, the number of N is four, that is, four positioning telescopic pins 81, four printed positioning pin holes 82 and four forged positioning pin holes 83. The projection of the four positioning telescopic pins 81 on the horizontal plane is consistent with the projection of the four printed positioning pin holes 82 and the forged positioning pin holes 83 on the horizontal plane, so as to ensure that when the forming cylinder housing 20 moves to the printing opening 11 or the forging opening 12, the positioning telescopic pins 81 can be smoothly inserted into the printed positioning pin holes 82 or the forged positioning pin holes 83.

[0061] The mobile support mechanism includes a servo motor 31, a support base 32, and a housing lifting part. The servo motor 31, the housing lifting part, and the reading head 72 are all mounted on the support base 32. The output end of the housing lifting part is connected to the forming cylinder housing 20 to drive the forming cylinder housing 20 to move up and down. The servo motor 31 is driven by the forming cylinder track 21. The reading head 72 is electrically connected to the servo motor 31. By setting the reading head 72 to be electrically connected to the servo motor 31, the movement of the servo motor 31 can be controlled according to the movement distance obtained by the reading head 72 in conjunction with the magnetic scale. This allows the servo motor 31 to stop moving in time when the reading head 72 and the magnetic scale 71 need to stop. The housing lifting part allows the upper surface of the forming cylinder housing 20 to fit against the top of the equipment body 10. At the same time, the forming cylinder housing 20 can be moved downwards and separated from the upper surface of the equipment body 10 according to actual needs.

[0062] The hoisting assembly includes a hoisting opening 13 on the top of the equipment body 10. The hoisting opening 13 is a rectangular opening, and the size of the hoisting opening 13 corresponds to the molding substrate 23. The hoisting opening 13 is located above the molding cylinder track 21 and on the extension line of the straight layout.

[0063] The hoisting assembly also includes a switchable airtight door 131 located at the hoisting opening 13. Preferably, the hoisting opening 13 is also provided with a hoisting positioning pin hole that engages with a positioning telescopic pin 81. Similarly, when moving to the hoisting opening 13, the scale of the magnetic scale 71 and the reading head 72 can be set for the first hoisting positioning. Then, the positioning telescopic pin 81 engages with the hoisting positioning pin hole for the second hoisting positioning. The first and second hoisting positioning ensures the accuracy of the hoisting. By setting the hoisting opening 13, after all the additive molding is completed, the molding substrate 23 can be moved to the position of the hoisting opening 13 under the conveying of the molding cylinder housing 20. The molded part located on the molding substrate 23 after printing is removed through the hoisting opening 13 by the molding cylinder body 22 so that the hoisting and removal of the part can be completed by using external hoisting tools. The switchable airtight door 131 adopts a mature method in the prior art. To ensure airtightness, a sealing strip can be added to the edge of the switchable airtight door 131.

[0064] When the bearing drive mechanism moves the forming cylinder housing 20 to below the printing assembly, the reading head 72, in conjunction with the magnetic scale 71, performs the first printing positioning of the forming cylinder housing 20. Specifically, the stop position of the printing opening 11 corresponding to the magnetic scale 71 is preset, and the deceleration position of the servo motor 31 before moving the forming cylinder housing 20 to below the printing opening 11 is also preset. When the servo motor 31 moves the forming cylinder housing 20, the reading head 72 decelerates after passing the deceleration position and stops immediately upon reaching the stop position. The first printing positioning is achieved through the reading head 72 in conjunction with the magnetic scale 71. The positioning telescopic pin 81 is inserted into the printing positioning pin hole 82 to perform the second printing positioning of the forming cylinder housing 20. Specifically, when the first printing... After the printing positioning, the telescopic cylinder 811 drives the insertion pin 812 to be inserted into the printing positioning pin hole 82. Under the action of the insertion pin 812 and the printing positioning pin hole 82, the forming cylinder housing 20 performs a second printing positioning to ensure further positioning accuracy. Subsequently, the forming cylinder body 22 drives the forming substrate 23 to move upward and enter the corresponding channel of the printing component, so that the forming substrate 23 is located at the printing station. Specifically, when the bearing drive mechanism drives the forming cylinder housing 20 to move below the printing component and after the first printing positioning and the second printing positioning, the forming cylinder housing 20 moves exactly to the position of the printing opening 11. The forming cylinder body 22 drives the forming substrate 23 to move through the printing opening 11 into the printing component for printing.

[0065] When the bearing drive mechanism moves the forming cylinder housing 20 to below the forging assembly, the reading head 72, in conjunction with the magnetic scale 71, performs the first forging positioning of the forming cylinder housing 20. Specifically, the stop position of the magnetic scale 71 corresponding to the forging opening 12 is preset, and the deceleration position of the servo motor 31 before moving the forming cylinder housing 20 to below the forging opening 12 is also preset. When the servo motor 31 moves the forming cylinder housing 20, the reading head 72 decelerates after passing the deceleration position and stops immediately upon reaching the stop position. The first forging positioning is achieved through the reading head 72 in conjunction with the magnetic scale 71. The positioning telescopic pin 81 is inserted into the forging positioning pin hole 83 to perform the second forging positioning of the forming cylinder housing 20. Specifically, when the first forging positioning... After positioning, the telescopic cylinder 811 drives the insertion pin 812 to insert into the forging positioning pin hole 83. Under the action of the insertion pin 812 and the forging positioning pin hole 83, the forming cylinder housing 20 is forged and positioned for the second time to ensure further positioning accuracy. Subsequently, the forming cylinder body 22 drives the forming substrate 23 to move upward and enter the corresponding channel of the forging assembly, so that the forming substrate 23 is located at the forging station. Specifically, when the bearing drive mechanism drives the forming cylinder housing 20 to move below the forging assembly and after the first forging positioning and the second forging positioning, the forming cylinder housing 20 moves exactly to the position of the forging opening 12. The forming cylinder body 22 drives the forming substrate 23 to move through the forging opening 12 into the forging box 51 for rolling and milling.

[0066] When the bearing drive mechanism moves the molding cylinder housing 20 to below the lifting assembly, similarly, when it moves to the lifting opening 13, the scale of the magnetic scale 71 and the reading head 72 can be set for the first lifting positioning. Then, the positioning telescopic pin 81 engages with the lifting positioning pin hole for the second lifting positioning. The first and second lifting positioning ensures the accuracy of the lifting. After the first and second lifting positioning, the molding cylinder body 22 moves the molding substrate 23 upwards until it is located at the lifting opening 13, placing the molding substrate 23 in the lifting position. The lifting opening 13 is designed so that after all additive molding is completed, the molding substrate 23 can be moved to the lifting opening 13 position by the molding cylinder housing 20 and then... The forming cylinder body 22 moves the printed part located on the forming substrate 23 to the position of the forming substrate 23 at the lifting opening 13, and then moves it out through the lifting opening 13 so that the part can be lifted and removed using external lifting tools. Correspondingly, the part can also be lifted and removed by using external lifting tools to reach into the lifting opening 13 without moving it out. The opening and closing airtight door 131 adopts a mature method in the prior art. To ensure airtightness, a sealing strip can be added to the edge of the opening and closing airtight door 131. Regarding the lifting and removal process, the forming substrate 23 and the forming part are lifted together by external lifting tools. Then, a new forming substrate 23 is placed on the moving end of the forming cylinder body 22 for subsequent additive forging. The removed forming substrate 23 and the forming part are separated by external tools, and finally the forming part is removed from the forming substrate 23.

[0067] During equipment operation, the bearing drive mechanism and forming cylinder body 22 are operated to move the forming substrate 23 to the printing station after the first and second printing positioning, completing the first printing process and obtaining the first printed body. The bearing drive mechanism and forming cylinder body 22 are operated again to move the forming substrate 23 to the forging station after the first and second forging positioning, completing the first forging process of the first printed body and obtaining the first forged body. Specifically, the rolling mechanism and milling mechanism, in conjunction with the rolling drive and milling drive, successively roll and mill the first printed body to form the first forged body, completing the first forging process. Subsequently, the bearing drive mechanism and forming cylinder body 22 are operated to return the forming substrate 23 to the printing station, completing the second printing process on the first forged body and obtaining the second printed body. The second printed body then enters the forging station for the second forging process to obtain the second forged body. The second printed body then enters the forging station. Under the combined action of the rolling drive and the milling drive, it undergoes a second forging process through rolling by the rolling mechanism and milling by the milling mechanism to obtain a second forged body. According to the above operating mode, based on the forming requirements, the forming substrate 23 switches between the printing station and the forging station to complete the cycle process of printing first and then rolling and milling to obtain the final formed part. Specifically, the above operating mode is to sequentially manufacture the third printed body, the third forged body, the fourth printed body, the fourth forged body, etc., according to the printing process of the first printed body, the forging process of the first forged body, the printing process of the second printed body, and the forging process of the second forged body, until the final formed part is formed. Forging is specifically a process flow of rolling first and then milling. After obtaining the final formed part, the bearing drive mechanism and the forming cylinder body 22 are operated to move the forming substrate 23 to the hoisting station for hoisting the formed part.

[0068] Specifically, when operating the bearing drive mechanism and the molding cylinder body 22, the bearing drive mechanism first moves the molding cylinder housing 20 to below the printing station at the printing opening 11, and then performs the first printing positioning and the second printing positioning. After the first printing positioning and the second printing positioning, the molding cylinder body 22 moves the molding substrate 23 out of the housing opening and into the printing station through the printing opening 11. After printing at the printing station, the molding cylinder body 22 moves the molding substrate 23 into the molding cylinder housing 20 through the printing opening 11. Then the first printing positioning and the second printing positioning are released, and the bearing drive mechanism and the molding cylinder body 22 are operated again.

[0069] When the load-bearing drive mechanism and the forming cylinder body 22 are operated again, the load-bearing drive mechanism first moves the forming cylinder housing 20 to below the forging station at the forging opening 12, and then performs the first forging positioning and the second forging positioning. After the first forging positioning and the second forging positioning, the forming cylinder body 22 moves the forming substrate 23 out of the housing opening and into the forging station through the forging opening 12. After being formed by rolling and then milling at the forging station, the forming cylinder body 22 moves the forming substrate 23 into the forming cylinder housing 20 through the printing opening 11. Then the first forging positioning and the second forging positioning are released, and the subsequent processing process is carried out.

[0070] Regarding the wind farm mechanism 42, the material feeding mechanism 43, the galvanometer body 44, the protective mirror 441, and the powder spreading mechanism 45;

[0071] Specifically:

[0072] The wind farm mechanism 42 includes a protective gas duct 421, a dust removal circulating air inlet duct 422, and a dust removal circulating air outlet duct 423. All three ducts are mounted on the printing box 41. The protective gas duct 421 and the dust removal circulating air inlet duct 422 are located on the same side, with the protective gas duct 421 positioned above the dust removal circulating air inlet duct 422. The dust removal circulating air outlet duct 423 is located on the other side. The dust removal circulating duct is used for gas circulation, and the protective gas duct is used for supplying protective gas. The duct layout and gas supply both utilize mature methods found in existing technologies.

[0073] The feeding mechanism 43 includes a hopper and a quantitative powder dispensing motor. The hopper is located on the printing box 41 and its inlet is located outside the printing box 41. The quantitative powder dispensing motor is located on the printing box 41 and inside the printing box 41. The quantitative powder dispensing motor is located at the outlet of the hopper. The supply of printing powder is realized through the hopper and the quantitative powder dispensing motor. Furthermore, all components of the feeding mechanism 43 adopt mature structures in the existing technology.

[0074] All components of the galvanometer body 44 adopt mature structures from existing technologies;

[0075] The powder spreading mechanism 45 includes a scraper motor and a scraper. Both the scraper motor and the scraper are located inside the printing box 41. The scraper motor drives the scraper to spread the powder. Furthermore, each component of the powder spreading mechanism 45 adopts a mature structure in the existing technology.

[0076] The printing assembly also includes structures found in other prior art printing devices that can ensure the printing requirements of this application;

[0077] The printing assembly is configured so that the printing process can be carried out after the molding substrate 23 is moved into the printing box 41;

[0078] By setting up a forging assembly so that the forging process can be carried out after the molding substrate 23 moves into the forging box 51, the printed body after printing a certain number of layers can be moved to the forging station in time by the moving support assembly for forging treatment of rolling and milling. Then it is moved back to the printing station to realize the cycle operation of printing-forging-printing-forging. Compared with the existing technology of forging after printing, the final printed body has fewer pores, higher density and performance.

[0079] Combined with appendix Figure 1-19 As shown, the number of molding cylinder tracks 21 is even, and each molding cylinder track 21 is provided with a rack 211. Preferably, there are two molding cylinder tracks 21, which are parallel to each other and located on a horizontal plane. The servo motor 31 corresponds to each molding cylinder track 21. The servo motor 31 includes a motor body 311 and a drive gear 312. The motor body 311 is mounted on the support 32. The output end of the motor body 311 is connected to the drive gear 312. The drive gear 312 meshes with the rack 211 on the corresponding molding cylinder track 21. The reading head 72 is electrically connected to the motor body 311. By setting the gear meshing relationship between the drive gear 312 and the rack 211, the molding cylinder housing 20 is driven more stably and accurately by the servo motor 31.

[0080] Combined with appendix Figure 1-19 As shown, the housing lifting unit includes a housing lifting motor 61 and a transmission conversion seat 62. The housing lifting motor 61 is mounted on the bearing seat 32 and is driven to the forming cylinder housing 20 through the transmission conversion seat 62. Specifically, the transmission conversion seat 62 is a worm gear structure. The lifting drive of the forming cylinder housing 20 is realized through the output end of the housing lifting motor 61 and the worm gear structure in the transmission conversion seat 62. The specific transmission conversion seat 62 is selected based on the worm gear structure according to actual needs, and all its components adopt mature structures in the existing technology.

[0081] Working Principle: The printing and forging components are activated. Powder is added to the feeding mechanism 43. The servo motor 31 moves the forming cylinder housing 20 below the printing component. After the first and second printing positioning, the forming cylinder body 22 moves the forming substrate 23 upwards, through the printing opening 11, into the printing box 41. Using the airflow mechanism 42, feeding mechanism 43, galvanometer body 44, protective mirror 441, and powder spreading mechanism 45, a certain number of layers are printed on the forming substrate 23. Subsequently, the forming cylinder body 22 moves the forming substrate 23 downwards into the forming cylinder housing 20. After releasing the first and second printing positioning, the servo motor 31 moves the forming cylinder housing 20 below the forging component. After the first and second forging positioning, the forming cylinder body 22 moves the forming substrate 23 upwards, through the forging opening 12, into the forging box 51. Using the rolling and milling mechanisms in conjunction with the rolling drive and milling drive, a certain number of layers are printed. The printed part on the molding substrate 23 undergoes a forging process involving rolling followed by milling. Subsequently, the molding cylinder body 22 moves the molding substrate 23 back into the molding cylinder housing 20, releasing the first and second forging positioning. The servo motor 31 then moves the molding cylinder housing 20 to the printing station for printing again. This printing-forging-printing-forging process is repeated until the final molded part is formed. Specifically, the forging process involves rolling followed by milling. Then, the servo motor 31 moves the molded part onto the molding cylinder body 23. 2. The final molded part, which has been moved into the molding cylinder housing 20, is moved to the hoisting opening 13. After the first hoisting positioning and the second hoisting positioning, the switch-sealed door 131 is opened, and the molding cylinder body 22 moves the molding substrate 23 upward, so that the final molded part is moved out of the hoisting opening 13 and is hoisted and picked up by the hoisting tool. During the printing-forging-printing-forging process, the printing box 41, the forging box 51 and the equipment body 10 are all protected by protective gas, which can be provided by the air field mechanism 42.
