Description

Technical Field

[0001] This application relates to the field of cutting protection technology, and in particular to a portable anti-splash device for a cutting machine. Background Technology

[0002] With the increasing demand for on-site operations in industries such as construction and shipbuilding, portable cutting machines have become an important tool in modern industrial production. However, the high-temperature sparks (3600-6000℃) and high-speed metal shavings (30m / s) generated during operation pose a serious threat to operators. Accidents caused by flying debris during cutting operations account for 34% of mechanical injury incidents (OSHA2024 data).

[0003] Existing protective solutions mainly rely on fixed metal covers (such as the protective covers in the GB / T 27607-2011 standard). For example, Chinese patent application number CN202020442708.3 discloses a cutting machine anti-splash device, which includes a sealed cavity near the cutting machine. The sealed cavity has an adsorption port at one end corresponding to the cutting machine. Multiple magnet blocks are arranged on the inner wall of the sealed cavity. The top surface of the sealed cavity is movably connected to the two side surfaces.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist:

[0005] Common fixed metal enclosures, with a single steel enclosure weighing over 15kg, are not convenient to move or reposition. The enclosed structure can lead to blind spots during operation, and most accidents involving abrasive cutting are caused by obstructed vision. In addition, the cost of cleaning and maintenance after use is high, and the accumulation of debris inside significantly increases the equipment failure rate. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0040] This application discloses a portable anti-splash device for a cutting machine. (Refer to...) Figure 1-3The portable cutting machine anti-splash device includes a support frame 1, a front baffle 2, a rear baffle 3, a top plate 4, and two side baffles 5. The front baffle 2 is fixed to the front end of the support frame 1, the rear baffle 3 is fixed to the rear end of the support frame 1, and the top plate 4 is fixed to the top of the support frame 1. The tops of the two side baffles 5 are respectively hinged to the opposite sides of the top of the support frame 1 by self-lubricating hinges. The support frame 1 is welded from multiple steel bars. The front baffle 2, rear baffle 3, top plate 4, and two side baffles 5 are all corrugated plates.

[0041] In this embodiment, a vertically arranged portal frame 6 is also provided on the top of the support frame 1. A manual adjustment mechanism 7 is threadedly fitted on the top center of the portal frame 6. An adjustment rope 8 is provided between the bottom of the manual adjustment mechanism 7 and the bottom of the side baffle 5. Through holes 61 for the adjustment rope 8 to pass through are provided on both sides of the portal frame 6. The manual adjustment mechanism 7 drives the side baffle 5 to rotate through the adjustment rope 8 to adjust the unfolding angle of the side baffle 5.

[0042] The manual adjustment mechanism 7 includes a vertically arranged adjustment screw 71, which is threaded onto the gantry bracket 6. A winding drum 72 is fixed to the bottom of the adjustment screw 71, and the end of the adjustment rope 8 away from the side baffle 5 is fixed to the winding drum 72. A rotating handle 73 is also vertically connected to the top of the adjustment screw 71.

[0043] The manual adjustment mechanism 7 and adjustment rope 8 designed above, combined with the self-locking and height-adjustable characteristics of the adjusting screw 71 under threaded assembly, make it convenient for staff to adjust the unfolding degree of the side baffle 5 at any time. That is, the unfolding angle of the side baffle 5 can be easily adjusted and fixed.

[0044] To prevent the adjusting rope 8 from breaking easily, the adjusting rope 8 is made of stainless steel wire or ultra-high molecular weight polyethylene fiber rope. At the same time, to facilitate the connection and fixation of the adjusting rope 8 to the side baffle 5, a connecting block 9 is fixed at the bottom middle position of the side baffle 5. One end of the adjusting rope 8 is welded to the connecting block 9. A magnet is also embedded in the inner side of the connecting block 9. Thus, when the side baffle 5 is in the closed state, the magnet can also be magnetically fixed to the bottom outer side of the support frame 1, which has a temporary fixing effect and effectively prevents the side baffle 5 from easily rotating and unfolding.

[0045] In this embodiment, the support frame 1 includes a bottom rectangular frame 11, a top rectangular frame 12, and four columns 13. The bottom rectangular frame 11 is arranged horizontally, and the top rectangular frame 12 is arranged obliquely. The tops of the four columns 13 are respectively connected to the four corners of the top rectangular frame 12, and the bottoms of the four columns 13 are respectively connected to the four corners of the bottom rectangular frame 11. The front end of the top rectangular frame 12 is higher than the rear end. The support frame 1 is welded from multiple angle steels or multiple square steel pipes. The outer surfaces of the angle steels and square steel pipes are provided with a galvanized layer or an anti-rust coating. The corrugated plate is a Q235 thin steel plate, and the wave height of the corrugated plate is between 10-15 mm.

[0046] The support frame 1 designed above has a simple and sturdy structure, is not easy to bend or deform, has good impact resistance, effectively suppresses deformation caused by cutting vibration, and is easy to obtain materials, lightweight, and has low manufacturing cost.

[0047] The beneficial technical effects of the portable cutting machine anti-splash device according to the embodiments of this application are roughly as follows:

[0048] Not only is the structure robust and the protection effective, but the overall weight can also be controlled between 5-10kg, making it easier to handle and move. By rotating the assembled side baffle 5, this design can be unfolded into a non-enclosed structure. After unfolding the side baffle 5, the protective volume can be increased by 2-3 times, supporting the processing of long workpieces and improving the space utilization rate by more than 2 times. It is less likely to have blind spots during operation, reducing safety accidents caused by obstructed vision during abrasive wheel cutting. Moreover, unfolding the side baffle 5 makes it easy to clean the accumulated debris inside, reducing the equipment failure rate.

[0049] In other embodiments, in order to balance heat dissipation, noise reduction and further reduce weight, the wave plate is also provided with multiple holes, and the opening ratio of the wave plate is between 25% and 35%.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
