Description

Technical Field

[0001] The utility model relates to the technical field of metal processing auxiliary devices, in particular to a chip shielding device for metal processing. Background Technique

[0002] Metal processing, abbreviated as metalworking, refers to the production activities of humans processing materials composed of metal elements or mainly composed of metal elements with metal characteristics. Profile cutting is a common and indispensable metal processing activity, which is generally carried out by using a profile cutting machine during the processing. A profile cutting machine, also called a grinding wheel saw, is suitable for departments such as construction, hardware, petrochemical industry, mechanical metallurgy and hydropower installation. It is a commonly used device that can cut materials such as metal square flat tubes, square flat steels, I-beams, channel steels, carbon yuan steels, and yuan tubes.

[0003] When the existing profile cutting machine is working, due to the intense friction, part of the metal will turn into high-temperature and high-speed metal chips, and then turn into sparks and fly everywhere after contacting the air. Users need to be equipped with corresponding protective measures to avoid injury, which will bring inconvenience to the processing process. At the same time, the splashing chip sparks may splash onto people or objects around the processing environment, resulting in personal injury or damage to objects. Therefore, in view of the above problems, a chip shielding device for metal processing is proposed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a chip shielding device for metal processing. The outer shielding cover provided by the metal processing auxiliary device can shield chips during the processing process and prevent them from flying everywhere. In particular, since the outer shielding cover is rotationally connected to the rotating shaft of the cutting machine support, its movement trajectory can coincide with the movement trajectory of the cutting blade, so that the cutting blade can move freely within a certain angle range in the outer shielding cover, and the outer shielding cover will not interfere with the normal cutting operation. And one side of the outer shielding cover is a transparent baffle, which can facilitate workers to observe the profile cutting situation inside the cover and is convenient for operation, solving the technical problem that the existing profile cutting machine lacks a shielding measure that does not interfere with the cutting operation, resulting in the splashing of chips and sparks during the cutting process, which may cause adverse consequences.

[0005] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0006] A chip shielding device for metal processing includes a profile cutting machine, an outer shielding cover, which is rotationally connected to the rotating shaft of the profile cutting machine support through a rotating connecting piece, and an inner cover, which is installed on the front end face of the profile cutting machine motor, and the cutting blade of the profile cutting machine is rotatably arranged in the inner cover; wherein, the inner cover is arranged in the outer shielding cover and is in sliding contact with the outer shielding cover, and the outer shielding cover includes a cover shell and a transparent baffle, and the transparent baffle is detachably connected to the cover shell.

[0007] With the above structural form, the externally arranged shielding cover can shield debris during the processing to prevent it from splashing everywhere. Moreover, since the externally arranged shielding cover is rotationally connected to the rotating shaft of the profile cutting machine, its movement trajectory can coincide with that of the cutting blade. When the externally arranged shielding cover falls onto the base of the profile cutting machine, the cutting blade can freely move within a certain angular range inside it without driving the externally arranged shielding cover to move, so that the externally arranged shielding cover will not interfere with the normal cutting operation. One side of the externally arranged shielding cover is a transparent baffle, which can facilitate the worker to observe the profile cutting situation inside the cover and is convenient for operation.

[0008] In a possible implementation manner, the inner cover includes a sector-shaped cover body covering above the cutting blade of the profile cutting machine. At the centers of both sides of the sector-shaped cover body, an end connection ring and a sliding shaft are respectively fixedly arranged. The end connection ring is fixedly connected to the front end face of the motor of the profile cutting machine, and the output shaft of the motor passes through the end connection ring without contact.

[0009] With the above structural form, the sector-shaped cover body can divide the cutting blade of the profile cutting machine from the externally arranged shielding cover, avoiding direct contact between the externally arranged shielding cover and the blade when the externally arranged shielding cover is severely deformed or the connection fails, thus preventing accidents. At the same time, the end connection ring and the sliding shaft provide a necessary structural basis for the transmission connection between the inner cover and the externally arranged shielding cover.

[0010] In a possible implementation manner, the housing includes an end plate and a shielding baffle. A first guide groove is formed on the end plate, and the sliding shaft is slidably arranged in the first guide groove. A second guide groove is formed on the transparent baffle, and the end connection ring is slidably arranged in the second guide groove.

[0011] With the above structural form, when the worker rotates the cutting part of the profile cutting machine through the handle, since the inner cover is directly connected to the cutting part, the inner cover will move accordingly. As a result, the sliding shaft and the end connection ring slide in the first guide groove and the second guide groove respectively. When the cutting part of the profile cutting machine is lifted significantly after cutting is completed, the sliding shaft and the end connection ring will quickly move to the top of their respective guide grooves and apply an upward lifting force to the externally arranged shielding cover, lifting it with a lag. When cutting, when the cutting part of the profile cutting machine is pressed down, the externally arranged shielding cover will fall synchronously and first contact the base of the profile cutting machine to play a blocking role.

[0012] In a possible implementation manner, a first material passing opening is formed at the bottom of the end plate in a centered arrangement, and a second material passing opening is formed at the bottom of the transparent baffle in a centered arrangement.

[0013] With the above structural form, the first material passing opening and the second material passing opening can provide a necessary structural basis for the passage of the profile.

[0014] In a possible implementation, two sets of symmetrically arranged heat dissipation holes are provided on the end plate, and each single heat dissipation hole is in a long strip shape.

[0015] With the above structural form, the heat dissipation holes can play a role in heat dissipation, avoiding excessive heat accumulation inside the cover and affecting the normal operation of workers.

[0016] In a possible implementation, the rotating connecting piece includes a connecting curved plate fixedly connected to the cover shell. Connecting pieces are fixedly connected to both sides of the connecting curved plate, and through holes are provided on the connecting pieces, and the size of the through holes is the same as that of the rotating shaft of the support of the profile cutting machine.

[0017] With the above structural form, the rotating connection with the rotating shaft of the support of the profile cutting machine can be achieved through the connecting pieces, and then the cover shell fixedly connected to the connecting curved plate is rotatably connected to the rotating shaft of the support of the profile cutting machine.

[0018] In a possible implementation, the transparent baffle is made of a transparent material resistant to high temperature, and it is connected to the cover shell by screws.

[0019] With the above structural form, it can ensure that the transparent baffle has a certain durability while playing its role, and the screw connection method can facilitate the replacement of the transparent baffle after it fails.

[0020] In a possible implementation, when the sliding shaft slides to the top of the first guide groove and the end connecting ring slides to the top of the second guide groove, there is still a gap between the upper part of the fan-shaped cover main body and the shielding baffle.

[0021] With the above structural form, it can avoid direct contact between the upper part of the fan-shaped cover main body and the shielding baffle, and can play a protective role for the internal fan-shaped cover main body and the internal blade.

[0022] In summary, the present utility model has the following beneficial technical effects:

[0023] The provided outer shielding cover can block debris during the processing process, avoiding its splashing everywhere. And since the outer shielding cover is rotatably connected to the rotating shaft of the profile cutting machine, its movement trajectory can coincide with the movement trajectory of the cutting blade. When the outer shielding cover falls onto the base of the profile cutting machine, the cutting blade can move freely within a certain angle range inside it without driving the outer shielding cover to move, so that the outer shielding cover will not interfere with the normal cutting operation. And one side of the outer shielding cover is a transparent baffle, which can facilitate workers to observe the profile cutting situation inside the cover and is convenient for operation.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0032] As Figure 1 - Figure 2 shown, a chip shielding device for metal processing provided in this embodiment includes a profile cutting machine 1, an outer shielding cover 2 which is rotatably connected to the rotating shaft of the support of the profile cutting machine 1 through a rotating connecting piece 3, and an inner cover 4 which is installed on the front end face of the motor of the profile cutting machine 1, and the cutting blade of the profile cutting machine 1 is rotatably arranged in the inner cover 4. Through the above structural form, the provided outer shielding cover 2 can shield chips during the processing process to prevent them from splashing everywhere, and since the outer shielding cover 2 is rotatably connected to the rotating shaft of the profile cutting machine 1, its movement trajectory can coincide with the movement trajectory of the cutting blade. When the outer shielding cover 2 falls onto the base of the profile cutting machine 1, the cutting blade can freely move within a certain angle range inside it without driving the outer shielding cover 2 to move, so that the outer shielding cover 2 will not interfere with the normal cutting operation.

[0033] Among them, the inner cover 4 is arranged in the outer shielding cover 2 and is in sliding contact with the outer shielding cover 2. The outer shielding cover 2 includes a cover shell 21 and a transparent baffle 22. The transparent baffle 22 is detachably connected to the cover shell 21. Since one side of the outer shielding cover 2 is the transparent baffle 22, it is convenient for workers to observe the cutting situation of the profiles inside the cover, which is convenient for operation. And the transparent baffle 22 is made of high-temperature resistant transparent material, and it is connected to the cover shell 21 by screws. This kind of material can ensure that the transparent baffle 22 has a certain durability while playing its role, and the screw connection method can facilitate the replacement of the transparent baffle 22 after it fails.

[0034] As Figure 3 - Figure 4 As shown, the inner cover 4 includes a sector-shaped cover main body 41 covering the cutting blade of the profile cutting machine 1. At the centers of both sides of the sector-shaped cover main body 41, an end connection ring 42 and a sliding shaft 43 are respectively fixedly arranged. The end connection ring 42 is fixedly connected to the front end face of the motor of the profile cutting machine 1, and the motor output shaft passes through the end connection ring 42 non-contact. The above technical solution can use the sector-shaped cover main body 41 to separate the blade of the profile cutting machine 1 from the outer shielding cover 2, avoiding direct contact with the blade when the outer shielding cover 2 is severely deformed or the connection fails, resulting in accidents. At the same time, the end connection ring 42 and the sliding shaft 43 provide a necessary structural basis for the transmission connection between the inner cover 4 and the outer shielding cover 2.

[0035] In addition, the cover shell 21 includes an end plate 211 and a shielding plate 212. A first guide groove 201 is opened on the end plate 211, and the sliding shaft 43 is slidably arranged in the first guide groove 201. A second guide groove 202 is opened on the transparent baffle 22, and the end connection ring 42 is slidably arranged in the second guide groove 202.

[0036] Through the above structural form, when the worker rotates the cutting part of the profile cutting machine 1 through the handle, since the inner cover 4 is directly connected to the cutting part, the inner cover 4 will move accordingly. Then, the sliding shaft 43 and the end connection ring 42 slide in the first guide groove 201 and the second guide groove 202 respectively. When the cutting part of the profile cutting machine 1 is lifted significantly after cutting, the sliding shaft 43 and the end connection ring 42 will quickly move to the top of their respective guide grooves and apply an upward lifting force to the outer shielding cover 2, lifting it with a delay. When cutting, when the cutting part of the profile cutting machine 1 is pressed down, the outer shielding cover 2 will synchronously drop and first contact the base of the profile cutting machine 1 to play a blocking role.

[0037] As Figure 3 - Figure 4 As shown, a first material passing opening 203 is arranged in the center at the bottom of the end plate 211, and a second material passing opening 204 is arranged in the center at the bottom of the transparent baffle 22. Through the above structural form, it can provide a necessary structural basis for the passage of profiles through the first material passing opening 203 and the second material passing opening 204.

[0038] As Figure 3 shown, two sets of symmetrically arranged heat dissipation holes 205 are provided on the end plate 211, and each single heat dissipation hole 205 is in a long strip shape. With the above structural form, the heat dissipation holes 205 can play a role in heat dissipation, avoiding excessive heat accumulation inside the cover and affecting the normal operation of workers.

[0039] As Figure 4 shown, the rotating connecting member 3 includes a connecting curved plate 31 fixedly connected to the cover 21. Connecting pieces 32 are fixedly connected to both sides of the connecting curved plate 31. Through holes 33 that are through and have the same size as the support rotating shaft of the profile cutting machine 1 are provided on the connecting pieces 32. With the above structural form, the connecting pieces 32 can be used to achieve rotational connection with the support rotating shaft of the profile cutting machine 1, and further rotate the cover 21 fixedly connected to the connecting curved plate 31 on the support rotating shaft of the profile cutting machine 1.

[0040] As Figures 3 - 5 shown, when the sliding shaft 43 slides to the top of the first guide groove 201 and the end connecting ring 42 slides to the top of the second guide groove 202, there is still a gap between the upper part of the sector-shaped cover body 41 and the shielding plate 212. With the above structural form, direct contact between the upper part of the sector-shaped cover body 41 and the shielding plate 212 can be avoided, and the internal sector-shaped cover body 41 and the internal blade can be protected.

[0041] The working principle and working process of the present utility model:

[0042] When a worker rotates the cutting part of the profile cutting machine 1 through the handle, since the inner cover 4 is directly connected to the cutting part, the inner cover 4 will move accordingly, and then the sliding shaft 43 and the end connecting ring 42 will slide in the first guide groove 201 and the second guide groove 202 respectively; when the cutting part of the profile cutting machine 1 is lifted significantly after cutting is completed, the sliding shaft 43 and the end connecting ring 42 will quickly move to the tops of their respective guide grooves and apply an upward lifting force to the outer shielding cover 2, lifting it with a delay. When cutting, when the cutting part of the profile cutting machine 1 is pressed down, the outer shielding cover 2 will synchronously drop and first contact the base of the profile cutting machine 1 to play a blocking role, blocking debris during the processing process and preventing it from flying everywhere.

[0043] The above technical solution can enable the cutting blade to freely move within a certain angle range inside the outer shielding cover 2 without driving the outer shielding cover 2 to move when the outer shielding cover 2 falls onto the base of the profile cutting machine 1, so that the outer shielding cover 2 will not interfere with the normal cutting operation. And since one side of the outer shielding cover 2 is a transparent baffle 22, it is convenient for workers to observe the profile cutting situation inside the cover and facilitate operation.

[0044] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
