Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printing technology based on welding technology, specifically to an automatic arc repair molding device. Background Technology
[0002] Rapid prototyping (RP) technology, also known as additive manufacturing technology, is a part prototype manufacturing technology that integrates CAD / CAM technology, laser processing technology, CNC technology, and new materials.
[0003] The existing automatic arc repair molding method usually uses an electric arc as a heat source to melt metal wires and build them up layer by layer to achieve repair or molding.
[0004] Existing technologies still have some shortcomings. In the process of forming materials, the material is usually placed inside the forming block, and the material is automatically repaired by the electric arc by closing the two forming blocks. However, during the closing process of the forming blocks, due to the lack of a precise positioning device for the forming blocks, the positions of the two forming blocks are easily offset after the forming blocks are closed, resulting in the inability to close accurately and affecting the accuracy of the material repair forming process. To address this, we propose an automatic electric arc repair forming device. Utility Model Content
[0005] The purpose of this invention is to provide an automatic arc repair and molding device, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic arc repair and forming device, including a mounting plate;
[0007] The controller is fixedly connected to the front of the mounting plate;
[0008] The device includes a molding assembly positioned above the mounting plate. The molding assembly comprises a support plate fixedly connected to the top of the mounting plate. First connecting blocks are fixedly connected to the four outer corners of the support plate. A first molding block is fixedly connected to the top of the support plate. A fixing column is fixedly connected to the top of the first connecting block. A second connecting block is fixedly connected to the other end of the fixing column. A top plate is fixedly connected to the side wall of the second connecting block. A first spring is fixedly connected to the bottom of the second connecting block. A limit block is slidably connected to the outer wall of the fixing column. A second molding block is fixedly connected to the side wall of the limit block. The other end of the first spring is fixedly connected to the top of the limit block. An L-shaped plate is fixedly connected to the top of the top plate. A cylinder is fixedly connected to the top of the inner wall of the L-shaped plate. The output end of the cylinder is fixedly connected to the top of the second molding block. By configuring the molding assembly, when the second molding block is pressed down and closes with the top of the first molding block, the operator can activate the first and second molding blocks by controlling the controller, thereby achieving arc repair molding of the internal material and improving the device's performance.
[0009] Preferably, the top of the mounting plate is further provided with a buffer assembly. The buffer assembly includes a rectangular block fixedly connected to the top of the mounting plate. A crossbar is fixedly connected to the inner wall of the rectangular block. Two sliders are slidably connected to the outer wall of the crossbar. A second spring is fixedly connected to the side wall of the slider. The other end of the second spring is fixedly connected to the inner wall of the rectangular block. A support rod is movably connected to the top of the slider via a hinge. The other end of the support rod is fixedly connected to the bottom of the limiting block via a hinge. By setting up the buffer assembly, when the second molding block moves downward, in order to avoid the second molding block directly colliding with the top of the first molding block and causing damage to both, it is necessary to buffer and limit the second molding block during the downward pressing process. When the second molding block moves downward, the support rod will rotate under the action of the hinge. During the rotation of the support rod, it will push the slider to move laterally along the outer wall of the crossbar and stretch the second spring. After the second spring, slider and support rod limit the second molding block and the limiting block, the buffer and limiting of the second molding block can be achieved, and the purpose of protecting the second molding block can be achieved.
[0010] Preferably, the bottom of the mounting plate is fixedly connected with four support legs. The four support legs are equidistantly fixedly connected to the bottom of the four corners of the mounting plate. By setting four support legs at the bottom of the mounting plate, stable support for the mounting plate can be achieved.
[0011] Preferably, one inner wall of the limiting block is adapted to the outer wall of the fixing column, and the other side of the limiting block is fixedly connected to the top outer wall of the second forming block. By setting the limiting block, the limiting block can move along the outer wall of the fixing column during the downward movement of the second forming block, thereby limiting the second forming block and making it rise and fall smoothly.
[0012] Preferably, there are four limiting blocks, all of the same size, and the four limiting blocks are fixedly connected at equal intervals to the four corners of the top of the second forming block. By setting four limiting blocks, the four corners of the second forming block can be limited.
[0013] Preferably, the bottom outer wall of the slider is adapted to the inner wall of the rectangular block, and the bottom inner wall of the slider is adapted to the outer wall of the crossbar, so that the slider can move laterally along the outer wall of the crossbar to limit the second forming block during the lifting process.
[0014] This invention provides an automatic arc repair and forming device. This automatic arc repair and forming device has the following advantages:
[0015] (1) The automatic arc repair molding device, by setting molding components, when it is necessary to automatically repair and mold the material by arc, the operator places the material on the top of the first molding block, and then opens the cylinder to cause the output end of the cylinder to extend and push the second molding block to move downward. When the second molding block moves downward, it will drive the limit block to move downward. The limit block will move downward along the outer wall of the fixed column. When the limit block moves downward, it will stretch the first spring. During the process, it can limit the second molding block when it is pressed down, and avoid the second molding block from being pressed down too fast and causing damage. When the second molding block is pressed down and closes with the top of the first molding block, the operator starts the first molding block and the second molding block by operating the controller to realize the arc repair molding of the material inside, which improves the use effect of the device.
[0016] (2) The automatic arc repair molding device, by setting a buffer component, when the second molding block moves downward, in order to avoid the second molding block directly colliding with the top of the first molding block and causing damage to both, it is necessary to buffer and limit the second molding block during the downward pressing process. When the second molding block moves downward, the support rod will be rotated by the action of the hinge. During the rotation of the support rod, the slider will be pushed to move laterally along the outer wall of the crossbar and stretch the second spring. After the second molding block and the limit block are limited by the second spring, the slider and the support rod, the buffer limit of the second molding block can be achieved, and the protection of the second molding block can be achieved.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0023] like Figure 1-4 As shown, this utility model has the following two specific embodiments.
[0024] Example 1
[0025] An automatic arc repair and molding device includes a mounting plate 1;
[0026] The controller 3 is fixedly connected to the front of the mounting plate 1;
[0027] The assembly includes a molding component 41 positioned above the mounting plate 1. The molding component 41 includes a support plate 411 fixedly connected to the top of the mounting plate 1. First connecting blocks 413 are fixedly connected to the outer walls of the four corners of the support plate 411. A first molding block 412 is fixedly connected to the top of the support plate 411. A fixing post 414 is fixedly connected to the top of the first connecting block 413. A second connecting block 415 is fixedly connected to the other end of the fixing post 414. A top plate 419 is fixedly connected to the side wall of the second connecting block 415. A first spring 416 is fixedly connected to the bottom of the second connecting block 415. A limit block 417 is slidably connected to the outer wall of the fixing post 414. A second molding block 418 is fixedly connected to the side wall of the limit block 417. The other end of the first spring 416 is fixedly connected to the top of the limit block 417. An L-shaped plate 4110 is fixedly connected to the top of the top plate 419. A cylinder 4111 is fixedly connected to the top of the inner wall of the L-shaped plate 4110. The output end of the cylinder 4111 is connected to the second molding block 412. The top of the 8 is fixedly connected. By setting the molding component 41, when the material needs to be automatically repaired by electric arc molding, the operator places the material on the top of the first molding block 412, and then opens the cylinder 4111 to cause the output end of the cylinder 4111 to extend and push the second molding block 418 to move downward. When the second molding block 418 moves downward, it will drive the limiting block 417 to move downward. The limiting block 417 will move downward along the outer wall of the fixed column 414. When the limiting block 417 moves downward, it will stretch the first spring 416. During the process, it can limit the second molding block 418 when it is pressed down, and prevent the second molding block 418 from being pressed down too fast and causing damage. After the second molding block 418 is pressed down and closed with the top of the first molding block 412, the operator controls the controller 3 to start the first molding block 412 and the second molding block 418 to realize the electric arc repair molding of the material inside, which improves the use effect of the device.
[0028] The bottom of the mounting plate 1 is fixedly connected with four support legs 2. The four support legs 2 are fixedly connected at equal intervals at the bottom of the four corners of the mounting plate 1. By setting four support legs 2 at the bottom of the mounting plate 1, stable support for the mounting plate 1 can be achieved.
[0029] One inner wall of the limiting block 417 is adapted to the outer wall of the fixing column 414, and the other side of the limiting block 417 is fixedly connected to the top outer wall of the second forming block 418. By setting the limiting block 417, the limiting block 417 can move along the outer wall of the fixing column 414 during the downward movement of the second forming block 418, thereby limiting the second forming block 418 and making it rise and fall smoothly.
[0030] There are four limiting blocks 417, all of equal size, and the four limiting blocks 417 are fixedly connected at equal intervals to the four corners of the top of the second forming block 418. By setting four limiting blocks 417, the four corners of the second forming block 418 can be limited.
[0031] The bottom outer wall of slider 423 is adapted to the inner wall of rectangular block 421, and the bottom inner wall of slider 423 is adapted to the outer wall of crossbar 422, which enables slider 423 to move laterally along the outer wall of crossbar 422, thereby limiting the second forming block 418 during the lifting process.
[0032] Example 2
[0033] The difference from Embodiment 1 is that this embodiment discloses a buffer component, such as... Figure 4 As shown:
[0034] A buffer assembly 42 is also provided on the top of the mounting plate 1. The buffer assembly 42 includes a rectangular block 421 fixedly connected to the top of the mounting plate 1. A crossbar 422 is fixedly connected to the inner wall of the rectangular block 421. Two sliders 423 are slidably connected to the outer wall of the crossbar 422. A second spring 424 is fixedly connected to the side wall of the slider 423. The other end of the second spring 424 is fixedly connected to the inner wall of the rectangular block 421. A support rod 425 is movably connected to the top of the slider 423 via a hinge. The other end of the support rod 425 is fixedly connected to the bottom of the limiting block 417 via a hinge. By setting the buffer assembly 42, when the second molding block 418 moves downward, to prevent the second molding block from moving downward, the buffer assembly 422 is used to prevent the second molding block from moving downward. The second molding block 418 directly impacts the top of the first molding block 412, causing damage to both. Therefore, it is necessary to buffer and limit the second molding block 418 during the downward pressing process. When the second molding block 418 moves downward, the support rod 425 will rotate due to the action of the hinge. During the rotation, the support rod 425 will push the slider 423 to move laterally along the outer wall of the crossbar 422 and stretch the second spring 424. After the second spring 424, the slider 423 and the support rod 425 limit the second molding block 418 and the limiting block 417, the buffer and limit of the second molding block 418 can be achieved, thus achieving the purpose of protecting the second molding block 418.
[0035] Working principle: When it is necessary to automatically repair and shape materials by electric arc, the operator places the material on the top of the first shaping block 412, and then opens the cylinder 4111, causing the output end of the cylinder 4111 to extend and push the second shaping block 418 downward. When the second shaping block 418 moves downward, it will drive the limiting block 417 to move downward. The limiting block 417 will move downward along the outer wall of the fixed column 414. When the limiting block 417 moves downward, it will stretch the first spring 416. During the process, it can limit the second shaping block 418 when it is pressed down, so as to prevent the second shaping block 418 from being pressed down too quickly and causing damage. After the second shaping block 418 is pressed down and closes with the top of the first shaping block 412, the operator controls the controller 3 to start the first shaping block 412 and the second shaping block 418, so as to realize the electric arc repair and shaping of the material inside, which improves the use effect of the device.
[0036] As the second molding block 418 moves downward, to prevent it from colliding directly with the top of the first molding block 412 and causing damage, it is necessary to buffer and limit the second molding block 418 during the downward movement. As the second molding block 418 moves downward, the hinge will cause the support rod 425 to rotate. During the rotation, the support rod 425 will push the slider 423 to move laterally along the outer wall of the crossbar 422 and stretch the second spring 424. After the second spring 424, the slider 423 and the support rod 425 limit the second molding block 418 and the limiting block 417, the buffer and limiting of the second molding block 418 can be achieved, thus achieving the purpose of protecting the second molding block 418.
[0037] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
