Description

Technical Field

[0001] The utility model relates to the technical field of mechanical protection devices, in particular to a cutting machine protection cover. Background Art

[0002] In existing steel enterprises, cutting machines are often required for cutting small batches of profiles. The iron filings and worn saw blade slag cut by the cutting machine during the cutting operation are likely to cause splashing. The existing cutting machine has its own protective cover installed above the saw blade of the cutting machine to protect the human body above the saw blade of the cutting machine. However, the lower part of the saw blade cannot be protected because it needs to cut profiles. During the cutting operation, iron filings and the residue after the saw blade is worn are likely to fly out from the lower part of the saw blade. On the one hand, the finer particles of the iron filings and residues are suspended in the air, causing air pollution. On the other hand, the coarser particles of the iron filings or residues are likely to cause harm to the human body, especially when the saw blade is broken due to improper operation, the broken saw blade flies out from under the protective cover, which is likely to pose a serious threat to the human body.

[0003] The Chinese utility model patent with application number 202022259998.0 discloses a protective cover for a grinding wheel cutting machine, comprising an outer cover body and an inner cover body. The cross-sectional shape of the outer cover body is set to be fan-shaped, the inner cover body is set to be semicircular, an arc-shaped slide groove is set inside the outer cover body, and the inner cover body is slidably set in the arc-shaped slide groove. The protection range of the protective cover is increased or reduced by sliding the inner cover body. However, because the profile needs to be cut under the saw blade on the cutting machine, the cutting machine cannot be fully protected.

[0004] In summary, there is an urgent need for a cutting machine protective cover to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] Example:

[0030] See also Figure 1-Figure 6 The present embodiment provides a cutting machine protective cover, including a base 1, a front baffle 2 and a rear baffle 3 are respectively arranged at the front and rear of the base 1, the front baffle 2 and the rear baffle 3 are arranged at intervals, and a accommodating area 4 is formed between the front baffle 2 and the rear baffle 3, and the left and right ends of the accommodating area 4 are connected to the outside for feeding, and an operating groove 21 and a transparent visual window 22 are provided on the front baffle 2, the operating groove 21 is arranged to extend vertically, and the visual window 22 is located on the side of the operating groove 21.

[0031] It can be understood that the cutting machine 5 is installed in the accommodating area 4, and the operating handle 52 of the cutting machine 5 extends from the operating slot 21. When performing the cutting operation, the profile to be cut is inserted from both ends of the accommodating area 4, and is cut by operating the operating handle 52 of the cutting machine 5. During the cutting process, the positional relationship between the saw blade 51 on the cutting machine 5 and the cutting profile is observed through the transparent visual window 22, which is convenient for the cutting operation. During the cutting process, the front baffle 2, the base 1 and the rear baffle form a barrier area for the cutting machine 5 to block and protect the front, bottom and rear of the cutting machine 5, so as to prevent the iron filings generated by the cutting of the cutting machine 5 from flying out and injuring people, reduce the safety threat caused by the flying iron filings to the operator, and improve the safety of the equipment; in addition, the barrier area blocks the hot iron filings in the barrier area to prevent the hot iron filings from flying out and causing a fire. In this embodiment, the visual window 22 is made of inorganic glass. Compared with organic glass, inorganic glass has better flame retardant properties to prevent fire.

[0032] Furthermore, a chip collecting assembly 31 is provided on the rear baffle plate 3, and a collecting port 32 is provided on the rear baffle plate 3, and the chip collecting assembly 31 and the collecting port 32 are docked. The iron chip collecting component 31 matches the position of the saw blade 51 of the cutting machine 5. When the cutting machine 5 cuts the profile, most of the iron chips will be ejected backwards from the tangent line where the saw blade 51 of the cutting machine 5 is tangent to the profile (the reason for ejecting backwards along the tangent line is that when the saw blade 51 of the cutting machine 5 is cutting the profile, the position where the saw blade 51 contacts the profile moves backwards relative to the profile, thereby driving most of the cut iron chips to move backwards and fly backwards along the tangent line at the cutting position, and a small part of the iron chips adhere to the saw blade 51 and are driven to other positions of the saw blade 51 and fly out along other tangent lines). The iron chip collecting component 31 is located on the tangent line where the saw blade 51 is tangent to the profile, so that the iron chips cut by the saw blade 51 and the residues produced by the wear of the saw blade 51 can smoothly enter the iron chip collecting component 31 for collection.

[0033] Furthermore, the iron chip collection assembly 31 includes a collecting hopper 311, a collecting barrel 312, and a connecting piece 313 for detachably connecting the collecting barrel 312 to the collecting hopper 311. The collecting hopper 311 is fixedly connected to the rear baffle 3, and one end of the collecting hopper 311 is docked with the collecting port 32, and the other end of the collecting hopper 311 is cantilevered outward and connected to the collecting barrel 312 through the connecting piece 313. In this embodiment, the connecting piece 313 is a bolt, and the collecting barrel 312 is a metal waste glue bucket with a handle. The bolt is detachably connected to the collecting hopper 311 through a thread, and the handle of the metal waste glue bucket is connected to the bolt by hanging, so that the metal waste glue bucket is hung on the collecting hopper 311. The collecting hopper 311 is cylindrical, and the outer surface of the collecting hopper 311 connected to the metal waste glue bucket is a spherical surface, which is connected to the circular barrel mouth of the metal waste glue bucket through the spherical surface to form a tight fit, so as to prevent the generation of a gap between the collecting hopper 311 and the collecting barrel 312, thereby preventing iron filings from flying out from between the collecting hopper 311 and the collecting barrel. The use of a metal waste glue bucket saves resources on the one hand, and reduces production costs on the other hand. In other embodiments, the collecting barrel 312 can also adopt other structures, such as directly using a sheet metal barrel to be fixedly connected to the collecting hopper 311 by bolts.

[0034] Furthermore, the collecting barrel 312 is arranged to be tilted downward from the front baffle 2 toward the rear baffle 3, and the head opening of the collecting barrel 312 is connected to the collecting hopper 311. The collecting barrel 312 is arranged tilted, so that the iron filings generated by cutting can slide from the mouth of the collecting barrel 312 into the collecting barrel 312 under the action of gravity, so that the iron filings and saw blade 51 slag generated by cutting can enter the collecting barrel 312 for collection.

[0035] Furthermore, the upper portion of the front baffle 2 extends upward and bends inward to form a front inclined plate 23, and an angle is formed between the front inclined plate 23 and the front baffle 2, and the size of the angle is between 90 degrees and 150 degrees. The front inclined plate 23 forms a barrier area in the front and upper part of the cutting machine 5 to prevent iron filings generated by cutting from flying out from the front and upper part; the upper portion of the rear baffle 3 extends upward and bends inward to form a rear inclined plate 33, and an angle is formed between the rear inclined plate 33 and the rear baffle 3, and the size of the angle is between 90 degrees and 150 degrees. The rear inclined plate 33 forms a barrier area in the rear and upper part of the cutting machine 5 to prevent iron filings generated by cutting from flying out from the rear and upper part.

[0036] Furthermore, the front baffle 2 is provided with a fixed angle cutting assembly 24, which includes a guide rail 241 and a fastener 242 for detachably connecting the guide rail 241 to the front baffle 2. In the present embodiment, the guide rail 241 is made of angle iron, one side of which is horizontally arranged to support the profile, and secondly to vertically position the profile, and the other side of the angle iron is vertically arranged to horizontally position the flat iron. The profile cut here is mainly flat iron, which is moved along the length direction of the rail to limit the feeding position of the flat iron. In the present embodiment, the fastener 242 is a bolt, and the guide rail 241 is detachably connected to the front baffle 2 by the bolt. In other embodiments, the guide rail 241 can also be other structures such as square tubes, and the fastener 242 can also be other structures or components such as rivets. The front baffle 2 is provided with a feed hole 25, which is set through the front baffle 2 and is located at the lateral lower part of the operating slot 21. The guide rail 241 is set corresponding to the feed hole 25, and the guide rail 241 forms an angle β26 with the front baffle 2. The extension line of the guide rail 241 is located below the saw blade 51 of the cutting machine 5. When cutting, the profile is moved along the guide rail 241 and inserted into the feed hole 25 to cut the profile. When the angle β26 between the guide rail and the front baffle 2 is different, the end face angle of the cut profile is also different. Here, the angle β26 is 30 degrees or 45 degrees, so as to facilitate the production of flat steel with an end face angle requirement of 30 degrees or 45 degrees (the front baffle 2 and the saw blade 51 of the cutting machine 5 are assumed to be vertical).

[0037] Furthermore, the fixed-angle cutting assembly 24 also includes a supporting foot 243, one end of which is fixedly connected to the guide rail 241, and the other end of the supporting foot 243 is used to support on the ground. The guide rail 241 is supported by the supporting foot 243, which increases the stability of the guide rail 241 and prevents the guide rail 241 from being deformed during use.

[0038] Furthermore, a plurality of fixed-angle cutting assemblies 24 are provided, and a plurality of feed holes 25 are provided on the front baffle plate 2 corresponding to different fixed-angle cutting assemblies 24. In different fixed-angle cutting assemblies 24, the angle β26 between the guide rail 241 and the front baffle plate 2 is different, and the angle β26 can be set between 0 degrees and 90 degrees (excluding 0 degrees). By inserting the profile from the guide rail 241 with different angles β26 for cutting, the required end face structures with different angles can be obtained. In the present embodiment, two fixed-angle cutting assemblies 24 are provided, namely, a fixed-angle cutting assembly 24 with an angle β26 equal to 30 degrees and a fixed-angle cutting assembly 24 with an angle β26 equal to 45 degrees.

[0039] Furthermore, a side baffle 27 extending toward the rear baffle 3 is provided on the inner wall surface of the front baffle 2, and the side baffle 27 is located on the side of the operation slot 21, and the side baffle 27 is located on the side of the operation slot 21 away from the visual window 22. In this embodiment, the side baffle 27 is fixed to the front baffle 2 by welding, and in other embodiments, the side baffle 27 can also be fixed to the front baffle 2 by screw connection or riveting. The side baffle 27 is mainly used to prevent iron filings generated during cutting from flying out to the side, and the side baffle 27 is located on the side of the operation slot 21 away from the visual window 22 to prevent the side baffle 27 from blocking the observation line of sight.

[0040] The operation flow and working principle of the cutting machine protective cover of the utility model are as follows: when it is necessary to cut the profile and obtain a flat end face, the profile can be extended into the cutting machine protective cover from the free positions on the left and right sides of the accommodating area 4, the cutting position is determined through the visual window 22, and the operating handle 52 of the cutting machine 5 is pressed to cut the profile. During the cutting process, a large amount of iron filings generated by the cutting are ejected backwards and enter the collecting hopper 311 through the collecting port 32 on the rear baffle 3, and enter the collecting bucket 312 through the collecting hopper 311 for collection. When the collecting hopper 311 is used, the collecting hopper 312 is used for collection. After the barrel 312 is full of iron filings, the connecting piece 313 connecting the collecting barrel 312 and the collecting hopper 311 is removed, the collecting barrel 312 is taken down, and the iron filings in the collecting barrel 312 are poured out, and then the collecting barrel 312 is reconnected to the collecting hopper 311 through the connecting piece 313. During the cutting process, the front baffle 2 and the front inclined plate 23 block the iron filings flying from the front and upper front of the cutting machine 5, the base 1 blocks the iron filings flying from the bottom of the cutting machine 5, and the rear baffle 3 and the rear inclined plate 33 block the iron filings flying from the rear and upper rear of the cutting machine 5. When the profile needs to be cut into an end face structure with a specific angle, the profile is placed on the guide rail 241 of the required fixed-angle cutting component 24, and the profile is moved along the guide rail 241 toward the cutting machine 5, so that the profile passes through the feed hole 25 and enters under the saw blade 51 of the cutting machine 5. The relative position of the profile and the saw blade 51 is observed through the visual window 22. After adjusting the position of the profile, the operating handle 52 of the cutting machine 5 is pressed to cut the profile.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
