Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Be a kind of embodiment with the Profile cut-off machine preventing Mars splashing function of the present invention as shown in Figure 1 to Figure 3, a kind of as shown in Figure 1 have the Profile cut-off machine preventing Mars splashing function, this Profile cut-off machine comprises: the protective hood of grinding wheel 2 playing operating grip 1 protective action of angular adjustment effect, emery wheel 3 for cutting during rotation is characterized in that, described abrasive machine also includes one for the flameproof enclosure 4 of Mars splatter guard, it is wrapped on the both sides of emery wheel and the emery wheel vertical plane of Mars splashing, its by afterbody staple 5 and head slide block 7 to match with slide bar 8 and realize with abrasive machine fixing, its operation principle is, the flameproof enclosure 4 when cutting, stop can not be caused to the sight line of cutting operation person, as shown in Figure 2 and its cutting time should be able to not because of the rising of emery wheel 3 or decline because changing, the while that now the performance of its protection Mars can not reducing, it can't impact cutting itself, described flameproof enclosure 4 afterbody is connected with afterbody staple 5 by afterbody connecting rod 6, afterbody connecting rod 6 can rotate around afterbody staple 5, and itself has elasticity, such setting makes it in the course of the work, because angle change can occur emery wheel 3, but its object all the time on horizontal plane carries out contacting the function forming cutting, so require that flameproof enclosure 4 also should ensure its vertical situation at any time, and be rotatably connected and just can realize such requirement, when emery wheel 3 rotates, flameproof enclosure 4 can rotatably match by connecting rod 6 under gravity, if the 3rd figure of Fig. 3 is when pulling lower handle 1, now connecting rod 6 power that suffers oppression is little, and itself there is elasticity, resilience rapidly flameproof enclosure 4 can be able to be pressed down fit with horizontal plane, described head slide block 7 can in the cofree slip of slide bar 8, arranging like this can make to form a kind of connection movably between flameproof enclosure 4 and protective hood of grinding wheel 2, be beneficial to the continuous change along with its angle in emery wheel 3 course of work like this, and flameproof enclosure 4 can remain a kind of effect straight down, procedure chart as Fig. 3 can be learnt, when slide block 7 moves on slide bar 8, only head connecting rod 9 can be made to move up and down thereupon, and angle change can not be there is, like this function that well ensure that its fire-proof and dust-proof is set, described flameproof enclosure 4 head is formed with head slide block 7 is hinged by head connecting rod 9, such setting is as above stated, all the time condition is provided straight down for flameproof enclosure 4, that avoids is fixedly connected with the drawback that its angle can change with tie point one, described slide bar 8 one end is fixed on protective hood of grinding wheel 2, and can rotate around tie point, the other end is free end, its length meets abrasive machine in the unlikely landing of each operating position head slide block 7, the slide block 7 that is set to like this provides motion path, make it can not depart from connecting rod 8 because of making in operation slide block 7 thus cause protection to lose efficacy, because emery wheel is in high-speed rotation time serious, easily make it stressed and fly away from, form the security incident of injury to personnel, and its to be rotatably connected be the basis kept relative stability in motion for flameproof enclosure 4 equally, described flameproof enclosure 4 is made up of refractory material, and itself be band pleated structure, due in the process of reality, because cutting speed is very fast, thus the broken last temperature produced is very high, as a large amount of Mars can be formed after the section steel cutting of metal species, if so the character not fire-resistant of anti-fire-spark arrester itself, resistant to elevated temperatures words its be easy to damage, its life-span is declined, but also itself can cause some potential safety hazards due to flameproof enclosure 4, its pleated structure then ensure that the scope that it will protect constantly changes, make it have enough cushion spaces can deacclimatize.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
