Description

Technical Field

[0001] This utility model relates to the field of alloy material spray forming, and in particular to an alloy material spray forming device. Background Technology

[0002] Alloy material spraying forming technology is an advanced manufacturing process that involves spraying molten or semi-molten alloy material at high speed onto the surface of a substrate, and then depositing it layer by layer to form a predetermined shape.

[0003] Traditional spray molding equipment still has certain limitations in terms of substrate fixation and finished product removal. Common equipment often uses mechanical clamping or bolts to fix the substrate, which is cumbersome to operate and difficult to guarantee stability under high-speed spray impact. After molding, the substrate often needs to be manually disassembled, which poses a safety hazard when operating in a high-temperature environment. Therefore, we propose an alloy material spray molding device. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1 to 3 The alloy material spray forming apparatus shown includes a spray forming machine body 1, a spraying mechanism 2 is provided in the spray forming machine body 1, the spraying mechanism 2 includes a spraying head 22 that can move laterally, the spraying head 22 is used for spray forming, and a spray forming platform 3 is vertically driven connected in the spray forming machine body 1, the spray forming platform 3 is used to cooperate with the spraying mechanism 2 to perform spray forming, and the spray forming platform 3 includes a lifting frame 31 and a forming substrate 32 installed on the lifting frame 31.

[0021] A movable seat 34 is slidably connected in the lifting frame 31, and a contact plate 321 and a snap-fit ​​seat 322 are provided below the molding substrate 32. The movable seat 34 has a first working position and a second working position.

[0022] In the first working position, the movable seat 34 cooperates with the snap-fit ​​seat 322 to limit the molding substrate 32;

[0023] In the second working position, the movable seat 34, in conjunction with the contact plate 321, pushes the molding substrate 32 out of the lifting frame 31.

[0024] By placing the molding substrate 32 in the lifting frame 31 and moving the movable seat 34 to engage with the locking seat 322, the molding substrate 32 is constrained, thereby ensuring the stability of the molding substrate 32 during alloy material spray molding and thus ensuring stability during the spray molding process. After the spray molding is completed, the movable seat 34 moves to contact the contact plate 321, pushing the molding substrate 32 upward to facilitate the removal of the molding substrate 32 and the heat treatment of the spray-molded item on the molding substrate 32.

[0025] The rigid snap-fit ​​structure between the movable seat 34 and the snap-fit ​​seat 322 effectively resists the impact and vibration during the spraying process, prevents the molding substrate 32 from shifting or loosening, and ensures the geometric accuracy and consistency of the molded parts. The inclined ejection mechanism driven by the cylinder 33 can realize the automatic lifting of the molded workpiece, reduce manual intervention, improve the efficiency of picking up parts, and reduce the operational risks in high-temperature environments.

[0026] Example 1: Both the movable seat 34 and the contact plate 321 are sloped, and the movable seat 34 and the contact plate 321 are arranged accordingly.

[0027] The movable seat 34 contacts the contact plate 321, thereby smoothly pushing the molding substrate 32 upward and pushing the molding substrate 32 out of the lifting frame 31.

[0028] The movable base 34 is provided with a docking seat 341 on the side near the card holder 322, and the card holder 322 is provided with a card slot on the side corresponding to the docking seat 341.

[0029] The movable seat 34 is moved so that the docking seat 341 is engaged in the slot, thereby engaging the movable seat 34 with the docking seat 322, thus confining the molded substrate 32 in the lifting frame 31 and ensuring the stability of the molded substrate 32 during processing.

[0030] Cylinders 33 are installed on both sides of the lifting frame 31, and the output end of the cylinder 33 is fixedly connected to the corresponding movable seat 34.

[0031] The cylinder 33 drives the moving seat 34 to move. The movement of the moving seat 34 is controlled to limit the molding substrate 32, or the movement of the moving seat 34 is controlled to push the molding substrate 32 out of the lifting frame 31.

[0032] Example 2: The main body 1 of the spray molding machine is connected to a transmission frame 21 in the transverse direction. The transmission frame 21 is equipped with a drive screw 23, and the spray head 22 is connected to the drive screw 23 in a transmission connection.

[0033] The spray head 22 is driven to move on the drive screw 23. In conjunction with the program set in the main body 1 of the spray molding machine, the spray head 22 is controlled to spray along the specified path, so that the alloy material is sprayed and formed on the molding substrate 32.

[0034] The main body 1 of the spray molding machine is equipped with a feed pipe 24, and a raw material hopper is connected to the feed pipe 24. The raw material in the raw material hopper is transported to the spray head 22 through the feed pipe 24.

[0035] Metal powder is stored in a raw material hopper and, driven by a powder feeder, is precisely and stably conveyed to the focal position of the nozzle 22 via the feed pipe 24. The feeding rate can be precisely controlled to ensure it matches the energy input and movement speed.

[0036] The nozzle 22 is a key actuator that integrates an energy source and a feed port. It is equipped with a high-energy source inside or at the front end, which can be set as a laser, electron beam gun, plasma arc, etc.

[0037] The high-energy beam generated by the energy source is precisely focused on the area above the molding substrate 32 to form a molten pool. At the same time, the alloy raw materials transported here are instantly heated to a molten or semi-molten state and incorporated into the molten pool.

[0038] The transverse moving transmission frame 21 and the drive screw 23 constitute a precise two-dimensional XY axis motion mechanism, which receives instructions from the control system and drives the spray head 22 to perform precise scanning motion according to the preset part slice contour path.

[0039] Vertical adjustment: The spray forming platform 3 forms the Z-axis. After each layer of deposition is completed, the lifting platform will descend one step according to the layer thickness to prepare for the deposition of the next layer.

[0040] Through this three-axis linkage, the nozzle 22 scans and deposits material layer by layer under program control, ultimately spraying the three-dimensional digital model into a solid part.

[0041] After the molten material leaves the focus of the energy beam, its heat is rapidly conducted to the already formed substrate below and the surrounding environment, resulting in rapid solidification.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
