Description

Technical Field

[0001] This invention belongs to the field of lost-wax casting technology, specifically referring to a wax model assembly tree welding device. Background Technology

[0002] Lost-wax casting is a traditional precision casting process. To improve production efficiency, multiple identical wax models are usually welded onto the pouring gate in an orderly manner before casting, forming a tree-like structure (called a "wax tree") so that subsequent processes such as slurry application and shell making can be completed in one go.

[0003] However, during the wax pattern assembly and welding process, each wax pattern needs to be welded to the sprue bar individually. This requires repeated picking and placing of the wax patterns, resulting in the welding torch frequently being in a waiting state. Furthermore, to complete welding on different sides, the sprue bar needs to be flipped. These repetitive operations severely impact overall work efficiency. In addition, gaps may exist between the welded wax pattern and the sprue bar, and compensating for these defects often requires additional welding time, further restricting capacity expansion. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a wax model tree welding device, which at least partially solves the above problems.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a wax model tree welding device, comprising: The workbench has a rotating rod in the upper middle part, an inclined rod with a height lower than the rotating rod on its side, and an adjustable rod that can be raised and lowered on the side opposite to the inclined rod. The feeding box is rotatably mounted on the rotating rod. The upper wall and one side wall of the feeding box are open structures. Multiple parallel partitions are provided inside the feeding box. The discharge end of each partition is provided with an inclined plate. Each discharge end of the partition is also hinged with two anti-detachment plates. A support spring is connected between the two anti-detachment plates. Two clamping assemblies are rotatably positioned on the worktable in the area of ​​the welding station, and the two clamping assemblies can slide relative to each other to clamp the sprue bar used for welding the wax mold; The top plate is connected to the worktable by a clamping spring and can slide vertically, and the top plate is located below the clamping assembly.

[0006] Furthermore, the discharge end of the partition is symmetrically provided with limiting blocks to limit the opening angle of the anti-detachment plate.

[0007] Furthermore, adjustment blocks are provided on the upper part of both side walls of the workbench, and the two ends of the adjustment rod are respectively installed in the adjustment blocks on both sides; height adjustment bolts are vertically provided on the adjustment blocks, and the height adjustment bolts are threadedly connected to the workbench.

[0008] Furthermore, an anti-loosening spring is connected between the adjusting block and the worktable.

[0009] Furthermore, a first sleeve is rotatably provided on the side wall of the workbench, and a second sleeve is rotatably provided on the corresponding side of the feeding box. A force-applying rod is provided through the first sleeve, and the end of the force-applying rod can be slidably extended into the second sleeve.

[0010] Furthermore, the clamping assembly includes a positioning plate, a clamping pin, and a clamping screw; a threaded hole is provided on the side wall of the worktable, the clamping screw is threaded into the threaded hole, and is rotatably disposed in the positioning plate, and the clamping screw and the positioning plate are axially fixed relative to each other; when the clamping screw rotates, it can drive the positioning plate to move relative to the side wall of the worktable, and the clamping pin is rotatably mounted in the positioning plate.

[0011] Furthermore, one of the clamping components has multiple sets of limiting grooves on the circumferential side wall of the clamping column, and the corresponding side wall of the worktable has a slot, in which a card plate is slidably disposed, and the card plate is used to engage with the limiting groove to fix the circumferential position of the clamping column.

[0012] Furthermore, a cone is slidably provided at the inner end of the clamping column of one side clamping assembly, and a clamping spring is connected between the cone and the clamping column. A flip handle is also provided at the outer end of the clamping column.

[0013] The beneficial effects achieved by this invention are as follows: With the help of the partition and the anti-detachment plate, the feeding box can sequentially transport the wax molds one by one towards the pouring gate bar when tilted, thereby significantly reducing the waiting time of the welding gun caused by repeatedly picking up the wax molds and improving the welding efficiency; at the same time, the top plate can apply an upward supporting force to the welded wax molds that have been flipped down, so that they are tightly pressed against the pouring gate bar, effectively preventing gaps and improving the integrity and reliability of the welded structure.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] like Figures 1-4As shown in the figure, the wax model tree welding device proposed in this embodiment of the invention includes a worktable 1, a feeding box 2, and a clamping assembly 3. The feeding box 2 is used to hold the wax model, and two clamping assemblies 3 are configured and located on both sides of the feeding box 2 for fixing the pouring nozzle bar of the wax model. During the welding operation, in order to facilitate the picking up of the wax model in the feeding box 2, the wax model can automatically tilt and slide towards the pouring nozzle bar. During the feeding operation, the feeding box 2 can tilt to the opposite side to keep the wax model in the feeding box 2 in a stable state.

[0020] To achieve the above functions, a rotatable rod 12 is provided in the upper middle part of the workbench 1, and an inclined rod 11 with a lower height than the rotatable rod 12 is provided on its side. An adjustable rod 13 with adjustable height is provided on the side opposite to the inclined rod 11. The feed box 2 is rotatably mounted on the rotatable rod 12. Figure 1 As shown, when the feeding box 2 rotates towards the adjusting rod 13, that is, when the bottom wall of the feeding box 2 contacts the adjusting rod 13, the wax mold inside the feeding box 2 will slide towards the pouring nozzle; as Figure 3 As shown, when the feeding box 2 rotates in the direction of the tilting rod 11, that is, when the bottom wall of the feeding box 2 contacts the tilting rod 11, the wax mold in the feeding box 2 will slide away from the pouring nozzle bar, thereby preventing the material in the feeding box 2 from falling out accidentally.

[0021] Specifically, the upper wall and one side wall of the feeding box 2 are open structures. Multiple parallel partitions 6 are installed inside the feeding box 2. Wax molds are placed sequentially between adjacent partitions 6. Simultaneously, as... Figure 5 As shown, the discharge end of partition 6 is equipped with an inclined plate 9, which can be fixed after the angle is adjusted (not shown in the attached figure) to adapt to different working conditions. Each partition 6 discharge end is also hinged with two anti-detachment plates 7, and a support spring 8 connects the two anti-detachment plates 7. When the supply box 2 tilts towards the pouring nozzle, the wax mold between the partitions 6 will slide towards the inclined plate 9 under the action of gravity. Because the density and weight of the wax mold are relatively light, such as Figure 2 As shown, under the action of the anti-detachment plates 7 on both sides, the wax model will be blocked by the anti-detachment plates, so that it only reaches the position close to the sprue bar, and will not fall out of the feeding box 2. During welding, the operator holds the welding gun in one hand and gently moves the wax model above with the other hand to the position of the sprue bar and the welding gun, and the welding can be completed. There is no need to pick up the wax model repeatedly, which greatly reduces the welding waiting time and improves the welding efficiency.

[0022] During welding operations, the sprue bar needs to be welded on multiple surfaces, so the angle of the sprue bar often needs to be adjusted. Both clamping components 3 are rotatably set in the welding area of ​​the worktable 1. The sprue bar is clamped from both ends by the clamping components 3 and rotates with the clamping components 3 under the action of friction, thereby adjusting the angle of the sprue bar. At the same time, the length of the sprue bar may be different for different products, and the two clamping components 3 can slide relative to each other to adjust the distance between them.

[0023] After welding is completed, in order to ensure a tight connection between the wax model and the sprue bar and to avoid gaps in the welding area, a top plate 4 is connected to the worktable 1 by a clamping spring 5. The top plate 4 can slide vertically and is located below the clamping assembly 3. When the clamping assembly 3 rotates and drives the sprue bar to rotate, the wax model welded on the sprue bar also rotates. When the wax model reaches the top plate 4, it applies downward pressure to the top plate 4. Under the action of the clamping spring 5, the top plate 4 applies an opposite upward clamping support force to the wax model, thereby ensuring a tight connection between the wax model and the sprue bar.

[0024] In some embodiments, such as Figure 5 As shown, in order to avoid a large deviation in the angle between the two anti-detachment plates 7, thereby losing the effect of limiting the displacement of the wax model, a limiting block 10 is symmetrically provided on the discharge end of the partition plate 6. The limiting block 10 can limit the opening angle of the anti-detachment plate 7, so that the wax model can be blocked by the anti-detachment plate 7, but will not hinder the sliding of the wax model during the welding operation, so that the wax model can overcome the resistance of the support spring 8 and be easily pushed out.

[0025] In some embodiments, such as Figure 4 As shown, adjustment blocks 14 are provided on the upper sides of both sides of the worktable 1. The two ends of the adjustment rod 13 are respectively installed in the adjustment blocks 14 on both sides. The adjustment block 14 is vertically provided with the height adjustment bolt 16, which is threadedly connected to the worktable 1. Rotating the height adjustment bolt 16 causes it to move up and down relative to the worktable 1, thereby driving the adjustment block 14 to move up and down, ultimately causing the height of the adjustment rod 13 to change. When the height of the adjustment rod 13 changes, the angle of the feeding box 2 tilting towards the working side also changes. The angle adjustment of the adjustment rod 13 is mainly to compensate for the adjustment limitation of the inclined plate 9. It works with the inclined plate 9 to adjust the angle of the wax model when feeding, so that the wax model is at a more suitable angle. In order to maintain the stability of the adjustment block 14, an anti-loosening spring 15 is connected between the adjustment block 14 and the worktable 1. The anti-loosening spring 15 provides an upward support force, so that there is greater friction between the adjustment block 14 and the height adjustment bolt 16, preventing shaking.

[0026] In some embodiments, to reduce the workload during welding operations and to make it easier to rotate the feed box 2, such as... Figure 3 and Figure 6As shown, a first sleeve 19 is rotatably provided on the side wall of the workbench 1, and a second sleeve 20 is rotatably provided on the corresponding side of the feed box 2. A force-applying rod 21 is passed through the first sleeve 19, and the end of the force-applying rod 21 can slide into the second sleeve 20. The distance between the force-applying end of the force-applying rod 21 and the first sleeve 19 is greater than the distance between the second sleeve 20 and the first sleeve 19. Under the action of the lever principle, the feed box 2 can be easily rotated by rotating the force-applying rod 21. The shape of the force-applying rod 21 can be designed to be more flexible and bendable according to the actual working conditions, so that the force-applying end of the force-applying rod 21 is easy to hold and operate.

[0027] In some embodiments, such as Figure 4 and Figure 7 As shown, the clamping assembly 3 includes a positioning plate 22, a clamping column 23, and a clamping screw 24. A threaded hole 17 is provided on the side wall of the worktable 1. The clamping screw 24 is threadedly engaged with the threaded hole 17 and is rotatably disposed in the positioning plate 22. The clamping screw 24 and the positioning plate 22 are axially fixed relative to each other. When the clamping screw 24 rotates, it can drive the positioning plate 22 to move relative to the side wall of the worktable 1. The clamping column 23 is rotatably installed in the positioning plate 22. When the positioning plate 22 slides relative to the worktable 1, the clamping column 23 slides along with it, thereby changing the distance between the two clamping columns 23 so as to clamp pouring gate bars of different lengths.

[0028] In some embodiments, after flipping the sprue bar, in order to keep the angle of the sprue bar fixed, a plurality of limiting grooves 27 are provided on the circumferential side wall of the clamping column 23 of one side clamping assembly 3, and a slot 18 is provided on the side wall of the corresponding side of the worktable 1. A locking plate 29 is slidably provided in the slot 18. When flipping the sprue bar, the locking plate 29 is first pulled out from the slot 18, and after rotating the sprue bar, the locking plate 29 is then inserted into the slot 18 to fix the angle of the clamping column 23 in the circumferential direction.

[0029] In some embodiments, in order to better clamp the sprue bar and better fix the axis of the sprue bar, a cone 25 is slidably provided on the inner end of the clamping column 23 of one side clamping assembly 3. A clamping spring 26 is connected between the cone 25 and the clamping column 23. During the clamping operation, the cone 25 is pushed into the center sprue of the sprue bar. Due to the difference in the diameter of the sprue, the cone 25 will be pushed into the sprue under the action of the clamping spring 26 until the cone 25 fits with the sprue. At this time, the sprue bar is completely fixed. The outer end of the clamping column 23 is also provided with a flip handle 28, which facilitates flipping operation outside the worktable 1.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
