Description

Technical Field

[0001] This utility model belongs to the field of construction machinery technology, specifically relating to a chamfering device for ALC panels. Background Technology

[0002] ALC panels, short for autoclaved lightweight aerated concrete panels, are a new type of lightweight wall material made from cement, lime, and silica sand as the main raw materials, with aluminum powder added as a foaming agent, and cured by high temperature and high pressure steam.

[0003] When using ALC panels, the sharp right-angled edges can increase the risk of cuts to workers during construction. Beveling eliminates this safety hazard. During installation, beveling prevents interference between panels, ensuring even mortar joints and more thorough sealant filling, making it particularly suitable for special areas such as door and window openings and wall corners. In terms of stress, right angles are prone to stress concentration leading to cracking, while beveling disperses stress and improves the wall's crack resistance. In addition, beveling makes the wall transition more natural, optimizes the visual effect after finishing, and ultimately reduces later maintenance costs, meeting the construction and quality requirements of prefabricated buildings.

[0004] Existing waterjet cutting machines use high pressure to accelerate water flow to extremely high speeds to impact and cut materials. During the cutting process, after the high-speed water flow impacts the ALC sheet, some of the water flow will change direction due to the reaction force of the sheet surface and splash in all directions, which can cause damage to the operator's skin. In addition, the splashed water mist will make the working area humid, thus causing pollution to the processing environment. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-4This utility model provides the following technical solution: a chamfering device for ALC sheet metal, comprising a cutting machine body 1, a mounting bracket 2 mounted on the surface of the cutting machine body 1, a cutting head 3 mounted on the surface of the mounting bracket 2, a limiting groove 4 formed on the bottom surface of the mounting bracket 2, a limiting block 5 inserted into the surface of the limiting groove 4, a slot 6 formed on the surface of the limiting block 5, a crossbar of the limiting frame 7 inserted into the surface of the slot 6, a threaded bolt assembly 8 connected to the side plate surface of the limiting frame 7, the limiting frame 7 being sleeved on the surface of the mounting bracket 2, a flow guide 9 connected to the bottom surface of the limiting block 5, a sealing strip 10 connected to the surface of the flow guide 9, and a movable inner wall surface of the sealing strip 10. The device is in contact with the surface of the flow guide shroud 9. The surface of the flow guide shroud 9 is connected to the fixing plate 11. The fixing plate 11 is bonded to the clamping post 12. The surface of the clamping post 12 is engaged and sleeved in the clamping groove 14 opened on the surface of the clamping plate 13. The surface of the clamping plate 13 is connected to the surface of the flow guide shroud 9. The inner wall surface of the flow guide shroud 9 is connected to the flow guide strip 15. In this design scheme, the cutting machine body 1, the mounting frame 2 and the cutting head 3 constitute the main body of the waterjet cutting machine. A large number of related components are set in the main body of the waterjet cutting machine. Since they are existing technologies and the core content of this technical solution is not related to them, they will not be described in detail in this technical solution.

[0023] The main model of the waterjet cutting machine in this solution is: DWJ2030-FB.

[0024] In use: The waterjet cutting machine first inputs the cutting program and parameters through the CNC operation panel, and sets the cutting path, water pressure, etc.; then the ALC sheet is placed on the worktable, the equipment is started, the high-pressure generating system starts working, and the generated ultra-high pressure water is treated by the water supply and filtration system and then delivered to the cutting head 3; the cutting head 3, supported by the gantry structure, moves in the X and Y axis directions according to the set program, spraying high-speed water jets to cut the ALC sheet and complete the processing task. During the process, the electrical control system precisely controls the operation of each component to ensure smooth cutting.

[0025] Preferably, the limiting groove 4 is a "T" shaped groove, the shape and size of which are adapted to the limiting plug 5, and the two limiting grooves 4 are symmetrically opened on the surface of the mounting bracket 2.

[0026] In practical use, the flow guide 9 is made of polycarbonate, which has high strength, high transparency and good impact resistance. It is not easy to break due to water splash impact or accidental collision. The limiting plug 5 connected to the top of the flow guide 9 is connected and inserted into the limiting groove 4 until the open ends of the two flow guides 9 are abutted together.

[0027] Preferably, the slot 6 is a circular through slot, the shape and size of which are adapted to the crossbar on the surface of the limiting frame 7, and the limiting frame 7 is an integral structure with one side of the arc strip connected to the crossbar.

[0028] In practical use, the crossbar of the limiting bracket 7 is inserted into the slot 6. After the side plates of the two limiting brackets 7 are joined together, the bolts, nuts and washers in the bolt assembly 8 are screwed together to tighten the two limiting brackets 7, thereby fixing the position of the upper end of the flow guide 9 on the mounting bracket 2.

[0029] Preferably, a semi-annular groove is formed on the surface of the mounting bracket 2, the shape and size of which are adapted to the two symmetrically distributed limiting brackets 7.

[0030] In actual use, the arc-shaped structure of the limit frame 7 is fitted into the semi-annular groove on the surface of the mounting frame 2.

[0031] Preferably, the flow guide shroud 9 has an inverted funnel-shaped structure, with three sets of flow guide strips 15 distributed in an annular pattern at equal intervals on its inner wall surface.

[0032] In practical use, the water flow is guided and constrained by the guide shroud 9 at the upper end of the cutting head 3. At the same time, the water splashed in the guide shroud 9 slides down through the guide strip 15 inside the guide shroud 9 and drips onto the worktable of the cutting machine body 1.

[0033] Preferably, the slot 14 is a circular through slot, the shape and size of which are adapted to the slot post 12.

[0034] In practical use, the silicone rubber post 12 engages with the slot 14 to fix the connection below the two air guides 9.

[0035] Working principle: When using the machine body 1 to chamfer ALC sheet, a guide shroud 9 of appropriate length is selected according to the thickness of the sheet. Then, the limiting block 5 connected to the top of the guide shroud 9 is connected and inserted into the limiting groove 4 until the open ends of the two guide shrouds 9 are brought together. The guide shroud 9 wraps around and guides the upper surface of the cutting head 3 to prevent the water jet from the cutting head 3 from splashing. When the two guide shrouds 9 are brought together, the sealing strip 10 connected to its surface is fitted into the gap at the open end of the other guide shroud 9 to block the gap between the two guide shrouds 9 and prevent water from splashing.

[0036] Then, the crossbar of the limiting bracket 7 is inserted into the slot 6, and the arc-shaped structure of the limiting bracket 7 is fitted into the semi-annular groove on the surface of the mounting bracket 2. After the side plates of the two limiting brackets 7 abut together, the bolts, nuts and washers in the bolt assembly 8 are screwed together to tighten the two limiting brackets 7, thereby fixing the position of the upper end of the flow guide 9 on the mounting bracket 2. At the same time, the fixing plate 11 and the clamping plate 13 connected below the flow guide 9 abut together. At this time, the clamping post 12 made of silicone rubber is clamped in the clamping groove 14, thereby fixing the connection below the two flow guides 9.

[0037] At this time, the processing parameters of the ALC plate placed on the worktable of the cutting machine body 1 can be set using the CNC panel on the cutting machine body 1. Then the cutting head 3 cuts the ALC plate. When the water flow splashes in all directions after impacting the surface of the ALC plate, the water flow is guided and constrained by the guide shroud 9 at the upper end of the cutting head 3. At the same time, the water flow splashed in the guide shroud 9 slides down through the guide strip 15 inside the guide shroud 9 and drips onto the worktable of the cutting machine body 1, thereby reducing the possibility of water flow splashing in all directions and also reducing its splash range.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
