Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and more specifically, to a flame cutting machine for processing a reducer housing. Background Technology

[0002] As a key structural component in mechanical transmission systems, the reducer housing is usually made of thick steel plates through cutting and welding. Its processing quality directly affects the assembly accuracy and service life of the entire machine. Currently, flame cutting technology is still widely used in the blanking and cutting of such large plates due to its advantages such as low cost and large cutting thickness.

[0003] Traditional cutting machines often employ fixed-track or simple cross-carriage structures, limiting the cutting path and making it difficult to perform precise cuts on complex curved surfaces or arbitrary contours. When machining reducer housings with various holes, grooves, and irregular shapes, multiple clamping or equipment changes are often required, resulting in large cumulative positioning errors, low processing efficiency, and poor adaptability to complex workpieces. Although some machines utilize conveyor rollers for material movement, the cutting head lacks sufficient freedom of movement, hindering effective coordination with the conveying system and limiting the improvement of its automation level. Furthermore, the flame cutting process generates a large amount of high-temperature, viscous molten metal oxide slag, also known as welding slag. This welding slag is extremely prone to splashing and adhering to the surface of the conveyor rollers. As the equipment operates, the accumulated welding slag can cause unevenness on the roller surface, leading to problems such as slippage, deviation, and even scratches on the workpiece surface during plate conveying, which seriously affects processing accuracy and product yield. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a flame cutting machine for processing reducer housing, which has the advantages of being able to achieve flexible and automated cutting and having a highly efficient self-cleaning function.

[0005] According to another aspect, the present invention provides the following technical solution: a flame cutting machine for processing a reducer housing, comprising a water storage base and a flame cutting machine body, wherein a material moving component for driving material movement is provided at the upper port of the water storage base, a gantry frame is installed in the middle of the upper side of the water storage base, a driving component for driving the flame cutting machine body to move is installed on the gantry frame, and a welding slag cleaning component is installed inside the water storage base, and the welding slag on the material moving component is cleaned by the welding slag cleaning component.

[0006] According to another aspect, the material moving assembly includes a frame fixedly installed at the port of the water storage seat, and a plurality of conveying rollers are rotatably mounted at equal intervals on the inner side of the frame.

[0007] According to another aspect, a servo motor is fixedly installed on the outside of the frame, and the output shaft of the servo motor is fixedly connected to the rotating shaft of the corresponding conveyor roller through a coupling. The rotating shafts of several conveyor rollers are connected by a number of gear pairs and chains.

[0008] According to another aspect, the welding slag cleaning and storage assembly includes a plurality of protective hoppers arranged in a rectangular array inside the water storage base, and a slag removal component located inside the water storage base below the frame base to perform friction slag removal on the outer sides of the plurality of conveying rollers.

[0009] According to another aspect, the top of the slag removal component is provided with a plurality of friction grooves adapted to a plurality of conveying rollers, and the top of the slag removal component is provided with a plurality of through grooves that are equidistant from each other and intersect with the plurality of friction grooves.

[0010] According to another aspect, a rectangular array of water inlet grooves is provided through the lower side of the outer surface of the protective hopper, and a hollow float is slidably installed through the top of the inner side of the protective hopper. The top of the hollow float is fixedly connected to the bottom of the slag removal component.

[0011] According to another aspect, the welding slag cleaning and storage assembly also includes a dividing frame and a bidirectional water pump fixedly installed inside the water storage base. The dividing frame divides the inner cavity of the water storage base into inner and outer layers, wherein several of the protective hoppers are located in the outer layer of the inner cavity of the water storage base, and the bidirectional water pump is installed inside the inner cavity of the water storage base.

[0012] According to another aspect, the drive assembly includes a rodless cylinder fixedly mounted on the top of the gantry, a rack slidably mounted on the rodless cylinder, a sliding frame seat slidably mounted on the outside of the rack, a mounting base fixedly mounted on one vertical end of the sliding frame seat, and the flame cutting machine body mounted on the mounting base.

[0013] According to another aspect, a frame block is fixedly installed on one end of the sliding frame seat away from the mounting base, and a slide rod is slidably installed on one end of the frame block in the vertical direction, extending through the inner side of the sliding frame seat. A toothed plate that engages with the toothed rod is fixedly installed on one end of the slide rod extending into the inner side of the sliding frame seat.

[0014] According to another aspect, a stop ring is fixedly installed on the outer surface of the slide rod located inside the frame block, and a spring is sleeved on the outer side of the slide rod, with the first and last ends of the spring respectively abutting between the stop ring on the outer side of the slide rod and the frame block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, the material is moved by a conveyor line composed of conveying rollers, and the flame cutting machine body is moved on the mounting base by a rodless cylinder. The two work together to realize the multi-degree-of-freedom movement of the cutting head relative to the material plane. This not only improves the conveying and positioning efficiency of large plates, but more importantly, it enables the flame cutting to flexibly perform complex contour cutting of arbitrary trajectories, greatly enhancing the adaptability and automation level of workpiece processing such as reducer housings.

[0016] 2. In this utility model, the high-temperature welding slag generated by the flame cutting machine body falls into the water and cools rapidly after passing through the gap of the conveying roller. At the same time, the buoyancy of the water makes the surface of the slag removal part continuously contact and rub against the rotating conveying roller. Thus, during the material conveying process, the welding slag adhering to the roller surface can be automatically and continuously scraped off. This self-cleaning mechanism fundamentally avoids problems such as uneven material conveying, slippage, or scratching of the workpiece surface caused by slag on the roller surface, ensuring the continuity and stability of production, and reducing the frequency and intensity of equipment maintenance.

[0025] like Figures 1 to 6As shown, this utility model provides a flame cutting machine for processing a reducer housing, including a water storage base 1 and a flame cutting machine body 3. A material moving component 5 for driving material movement is provided at the upper port of the water storage base 1. A gantry frame 2 is installed in the middle of the upper side of the water storage base 1. A driving component 4 for driving the flame cutting machine body 3 is installed on the gantry frame 2. A welding slag cleaning component 6 is installed inside the water storage base 1, and the welding slag on the material moving component 5 is cleaned by the welding slag cleaning component 6.

[0026] In actual use, the material moving component 5 is activated first, conveying the cutting machine to be processed laterally to the cutting area. Then, the drive component 4 starts working, driving the flame cutting machine body 3 to perform precise longitudinal coordinated movement within the plane formed by the gantry 2, thereby performing flame cutting of the steel plate with arbitrary contours according to the preset path. During the cutting process, the high-temperature welding slag generated will fall down through the gap of the conveying roller in the material moving component 5. At this time, the welding slag cleaning and storage component 6 starts to play its role: the falling welding slag first falls into the water in the water storage seat 1 and is cooled. At the same time, the component uses the buoyancy of the water to keep the slag removal component in contact with the lower surface of the conveying roller. When the conveying roller rotates, the welding slag attached to its surface is automatically scraped off and falls into the water, thereby realizing the online self-cleaning of the conveying roller and effectively preventing the accumulation of welding slag from affecting the smooth conveying of materials or scratching the surface of the workpiece.

[0027] The material moving component 5 includes a frame 51 fixedly installed at the port of the water storage seat 1, and a number of conveying rollers 52 are rotatably installed at equal intervals on the inner side of the frame 51. A servo motor 54 is fixedly installed on the outside of the frame 51. The output shaft of the servo motor 54 is fixedly connected to the rotating shaft of the corresponding conveyor roller 52 through a coupling. The rotating shafts of several conveyor rollers 52 are connected by several gear pairs and chains 53. The servo motor 54 can drive all the conveying rollers 52 to rotate synchronously and in the same direction, ensuring the stability and straightness of the material during the conveying process. This provides a stable benchmark for the flame cutting machine body 3 to achieve precise cutting. This design is not only efficient in transmission and compact in structure, but also simplifies the control system and reduces the manufacturing cost and maintenance complexity of the equipment.

[0028] Among them, the drive assembly 4 includes a rodless cylinder 41 fixedly installed on the top of the gantry 2, a toothed rod 42 slidably installed on the rodless cylinder 41, a sliding frame seat 43 slidably installed on the outside of the toothed rod 42, and a mounting seat 49 fixedly installed at one end of the sliding frame seat 43 in the vertical direction. The flame cutting machine body 3 is installed on the mounting seat 49. A frame block 45 is fixedly installed on the end of the sliding frame base 43 away from the mounting base 49. A slide rod 46 that extends through the inner side of the sliding frame base 43 is slidably installed on one end of the frame block 45 in the vertical direction. A toothed plate 48 that engages with the toothed rod 42 is fixedly installed on one end of the slide rod 46 that extends into the inner side of the sliding frame base 43. A stop ring is fixedly installed on the outer surface of the slide rod 46 inside the frame block 45. A spring 47 is sleeved on the outer side of the slide rod 46, and the two ends of the spring 47 abut against the stop ring on the outer side of the slide rod 46 and the frame block 45 respectively. The rodless cylinder 41 drives the rack 42 and the mounting base 49 to move, thereby driving the flame cutting machine body 3 mounted on the mounting base 49 to move together. In conjunction with the material moving component 5, the cutting object is moved to achieve precision cutting. Pulling the slide rod 46 moves the toothed plate 48 away from the toothed bar 42, thereby releasing the locking effect between the slide frame seat 43 and the toothed bar 42. This allows the slide frame seat 43 to slide and adjust the distance between the flame cutting machine body 3 and the workpiece. After adjusting the distance between the flame cutting machine body 3 and the workpiece, the slide rod 46 is released. The tension of the spring 47 pushes the slide rod 46 to reset the toothed plate 48, thus allowing the slide frame seat 43 to re-engage with the toothed bar 42.

[0029] Among them, the slag removal and storage component 6 includes a number of protective buckets 63 installed in a rectangular array inside the water storage base 1, and a slag removal component 62 located inside the water storage base 1 on the lower side of the frame base 51 to remove slag from the outside of a number of conveying rollers 52 by friction. The top of the slag removal component 62 is provided with a number of friction grooves 621 that are adapted to a number of conveying rollers 52, and the top of the slag removal component 62 is provided with a number of through grooves 622 that are equidistant from each other and intersect with the number of friction grooves 621. The lower outer surface of the protective hopper 63 has a rectangular array of water inlet grooves 631. The top inner side of the protective hopper 63 has a hollow float 64 that is slidably installed. The top of the hollow float 64 is fixedly connected to the bottom of the slag removal component 62. Welding slag falls into the water storage 1 through the gap between the conveying rollers 52. The water in the water storage 1 can quickly cool the high-temperature welding slag and prevent the welding slag from sticking to the water storage 1. The welding slag adhering to the outer surface of the conveying roller 52 rubs against the friction groove 621 opened on the slag removal part 62 when the conveying roller 52 rotates, thereby removing the welding slag adhering to the surface of the conveying roller 52 through rotational friction. The removed welding slag falls into the water storage seat 1 through the through groove 622 for centralized treatment. The slag removal component 62 floats on the water surface of the water storage base 1 through several hollow floats 64 at its four corners.

[0030] The welding slag cleaning and storage component 6 also includes a dividing frame 61 and a bidirectional water pump 611 fixedly installed inside the water storage base 1. The dividing frame 61 divides the inner cavity of the water storage base 1 into inner and outer layers, with several protective hoppers 63 located on the outer layer of the inner cavity of the water storage base 1, and the bidirectional water pump 611 installed on the inner side of the inner cavity of the water storage base 1.

[0031] The water inside the water storage seat 1 is transported to the outside of the water storage seat 1 by the bidirectional water pump 611. When the water level on the outside of the water storage seat 1 rises, the hollow float 64 rises with the water level. The hollow float 64 then pushes the slag removal component 62 more forcefully upward to get closer to the conveying roller 52, thereby increasing the friction between the slag removal component 62 and the frame seat 51.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
