[0072] See also Figure 1-8 The present invention provides a technical solution: a metal sheet cutting device, comprising:

[0073] The workbench 1 is arranged horizontally, and a strip window 8 is longitudinally opened in the middle of the upper surface of the workbench 1;

[0074] The front and rear side walls of the workbench 1 are fixedly equipped with an arched lifting frame 3, and the bottom surface of the upper end thereof is fixedly equipped with a lifting and cutting mechanism 4 and a negative pressure chip suction and liquid cooling component 5;

[0075] The negative pressure input end and the coolant output end of the negative pressure chip suction and liquid cooling component 5 are directed toward the cutting head of the lifting and cutting mechanism 4;

[0076] The inner wall of the workbench 1 is symmetrically equipped with strip window purge structures 10 on both sides, and the inner ends thereof are connected to the strip windows 8;

[0077] The upper surface of the workbench 1 is symmetrically fixed with a tabletop blowing mechanism 7 on both sides, with the wind direction facing the strip window 8;

[0078] An inclined plate upper and lower surface cleaning device 6 is fixedly mounted on the right end of the workbench 1 .

[0079] Specifically in this embodiment, the workbench 1 is a tabletop of a cutting device, and a strip window 8 is longitudinally provided in the middle thereof for discharging falling debris downwards. A storage container can be placed below the strip window 8 to collect the discharged debris. The negative pressure chip suction and liquid cooling component 5 integrates two functions, namely, a negative pressure dust suction function and a coolant spraying function.

[0080] This device is equipped with a PLC controller to control the operation of electrical equipment;

[0081] Furthermore, the arched lifting frame 3 and the lifting and cutting mechanism 4 cooperate to cut plates of different thicknesses on the workbench 1. During the cutting process, the cutting area is cooled by negative pressure suction and the liquid cooling component 5 sprays cooling water to reduce the splashing of debris. At the same time, the splashing debris is sucked away by negative pressure to reduce the amount of debris adhering to the surface of the plate. The negative pressure airflow acts on the cutting head to provide an auxiliary cooling effect.

[0082] Then, the blowing mechanism 7 on both sides of the table is used to blow wind toward the middle to blow away some debris adhering to the surface of the workbench 1. These debris fall into the strip window 8 and are discharged. The wind blowing is also an air cooling process.

[0083] More specifically, a strip window purge structure 10 is provided in the workbench 1 corresponding to the strip window 8, for blowing air toward the internal components of the strip window 8 to prevent debris from adhering to the outer wall of the internal components of the strip window 8;

[0084] The cut plate slides down along the inclined plate upper and lower surface cleaning device 6, and the residual debris adhering to the upper and lower surfaces of the plate is removed during the sliding process;

[0085] It is understood that in actual use, a bracket 2 is provided at the lower end of the workbench 1. When necessary, a lifting device such as a pad of different thicknesses or a base can be placed at the lower end of the bracket 2 to ensure that there is sufficient space for removing the plate that slides down the upper and lower surface cleaning device 6 of the inclined plate.

[0086] When the inclined plate upper and lower surface cleaning device 6 is in use, the plate that has been cut and cooled synchronously to remove most of the surface debris needs to slide in along the upper and lower slopes of the inclined plate upper and lower surface cleaning device 6. The feeding of the plate can be operated by a robot or manually wearing heat-insulating gloves. Wearing heat-insulating gloves can avoid the influence of the residual temperature of the plate after cooling.

[0087] In some embodiments, the negative pressure chip suction and liquid cooling component 5 includes:

[0088] A mounting plate 51, which is fixedly mounted on the bottom surface of the upper end of the arched lifting frame 3;

[0089] The mounting plate 51 is equipped with a negative pressure chip suction pipe and a liquid cooling output pipe;

[0090] The input end of the negative pressure chip suction pipe and the output end of the liquid cooling output pipe are both close to and facing the cutting head of the lifting cutting mechanism 4;

[0091] The output end of the negative pressure dust suction pipe passes through the mounting plate 51 and is fixedly connected to the external dust collection equipment;

[0092] The input end of the liquid cooling output pipe passes through the mounting plate 51 and is fixedly connected to the external cooling liquid supply device.

[0093] Specifically in this embodiment, the mounting plate 51 is fixed to the bottom surface of the slider below the linear module 33, and the lifting and cutting mechanism 4 is also fixed to the bottom surface of the slider below the linear module 33. As the slider moves, the negative pressure chip suction, liquid cooling component 5 and the lifting and cutting mechanism 4 move, and the relative positions of the negative pressure chip suction, liquid cooling component 5 and the lifting and cutting mechanism 4 are fixed;

[0094] Furthermore, the external dust collection equipment is a combination of a negative pressure fan and a bag dust collector. The negative pressure fan is connected to the output end of the pulse bag dust collector to generate negative pressure. The negative pressure acts on the input end of the pulse bag dust collector to suck in the smoke and debris generated by the plate cutting. The smoke and debris are filtered out by the pulse bag dust collector. The pulse bag dust collector is cleaned by backwashing using a pulse device.

[0095] The coolant supply device consists of a coolant storage tank and a water pump. The water pump pumps the coolant in the coolant storage tank into the liquid cooling output pipe for output. The coolant storage tank needs to be replenished with coolant regularly.

[0096] More specifically, the working status of the negative pressure fan and the water pump is controlled by the controller. The controlled quantities include the start and stop of the negative pressure fan and the water pump, which is the application of the basic function of the controller.

[0097] In some embodiments, the negative pressure debris suction duct comprises:

[0098] The first connecting elbow 53 has a gooseneck 54 fixedly connected to its lower end, and the lower end of the gooseneck 54 is close to and faces the cutting head of the lifting and cutting mechanism 4;

[0099] The upper end of the first connecting elbow 53 is fixedly connected to a first connector 52 , which passes through and is fixed on the mounting plate 51 .

[0100] Specifically in this embodiment, the first connecting elbow 53 is a metal pipe, and the gooseneck pipe 54 is an existing technology that can be bent and positioned arbitrarily, change direction and not rebound, so as to facilitate the adjustment of the lower end position of the negative pressure suction pipe;

[0101] Furthermore, the first connecting elbow 53 is bent at its lower end to connect to the gooseneck 54, so that the lower end of the gooseneck 54 is close to and faces the cutting head of the lifting and cutting mechanism 4;

[0102] It can be understood that the lower end of the cutting head of the lifting and cutting mechanism 4 is used for cutting the plate, and the lower end of the gooseneck tube 54 is close to the middle of the outer side of the cutting head.

[0103] In some embodiments, the liquid cooling output pipeline includes:

[0104] A second connecting elbow 56, the lower end of which is close to and faces the cutting head of the lifting and cutting mechanism 4;

[0105] The upper end of the second connecting elbow 56 is fixedly connected to a second connector 55 , which passes through and is fixed on the mounting plate 51 .

[0106] Specifically in this embodiment, the second connecting elbow 56 is a metal pipe, and its lower end surface is inclined toward the cutting head of the lifting and cutting mechanism 4;

[0107] Furthermore, the lower end of the second connecting elbow 56 is bent close to and toward the cutting head of the lifting and cutting mechanism 4;

[0108] It can be understood that the lower end of the cutting head of the lifting and cutting mechanism 4 is used for cutting the plate, and the lower end of the second connecting elbow 56 is close to the middle of the outer side of the cutting head.

[0109] In some embodiments, the strip window purge structure 10 includes:

[0110] A rectangular chamber 101 is provided at the upper end of the inner wall of the workbench 1;

[0111] The outer end of the rectangular chamber 101 on the outer wall of the workbench 1 is evenly fixed and connected with a branch pipe 103 along the length direction;

[0112] The outer end of the branch pipe 103 on the same side is fixedly connected to the main pipe 104, and both ends are sealed;

[0113] The middle part of the outer side of the main pipe 104 is fixedly connected with an air intake pipe 105;

[0114] A nozzle 102 is provided at the inner end of the rectangular chamber 101 along the length direction, and the inner end thereof is communicated with the strip-shaped window 8 .

[0115] Specifically in this embodiment, the air intake pipe 105 is used to connect to an external air pump for air supply;

[0116] Furthermore, the airflow enters the rectangular chamber 101 along the air inlet pipe 105, the air inlet pipe 105, and the branch pipe 103. The gas in the rectangular chamber 101 is sprayed from the nozzle 102 into the strip window 8 to purge and remove debris adhering to the outer wall of the device in the strip window 8.

[0117] More specifically, the components in the strip-shaped window 8 specifically refer to the bidirectional lead screw 93 and the mounting slider 94 .

[0118] In some embodiments, the inclined plate upper and lower surface cleaning device 6 includes:

[0119] Inclined plate 61, the upper end of which extends to the right end of the workbench 1;

[0120] A support frame 62 is fixedly mounted between the inclined plate 61 and the right end of the workbench 1;

[0121] Strip-shaped bristles 64 are evenly fixed and assembled on the upper surface of the inclined plate 61 along the length direction, and are arranged along the width direction of the inclined plate 61;

[0122] The strip-shaped bristles 64 are composed of first bristles evenly distributed along the width direction of the upper surface of the inclined plate 61;

[0123] A lifting brush mechanism 63 is evenly fixed and assembled on the upper side of the front and rear side walls of the inclined plate 61 along the length direction.

[0124] Specifically in this embodiment, there are two strip bristles 64 and two lifting bristle mechanisms 6; the inclined angle of the inclined plate 61 is 45 degrees;

[0125] Furthermore, as the cut plate slides down the inclined surface of the upper surface of the inclined plate 61, the bristles of the strip brush 64 clean the debris adhered to the bottom surface of the cut plate, and the bristles on the bottom surface of the lifting brush mechanism 6 clean the debris adhered to the top surface of the cut plate.

[0126] In some embodiments, the lifting bristle mechanism 63 includes:

[0127] The arched frame 631 has its lower ends fixedly connected to the front and rear side walls of the inclined plate 61;

[0128] A first electric push rod 632 is vertically fixedly mounted in the middle of the top surface of the arch frame 631, and a strip plate 633 is fixedly mounted on the lower end of the first electric push rod 632 which passes through the top surface of the arch frame 631;

[0129] Second bristles 634 are evenly adhered and fixed to the bottom surface of the strip plate 633 .

[0130] Specifically in this embodiment, the first electric push rod 632 is connected to the controller to adjust the extension amount, thereby controlling the height of the strip plate 633 and the second bristles 643 on the bottom surface;

[0131] Furthermore, by controlling the height of the second bristles 643 , within a certain range, the second bristles 643 can be fitted to the top surface of plates cut to different thicknesses, thereby improving practicality.

[0132] In some embodiments, the tabletop purge mechanism 7 includes:

[0133] The strip-shaped mounting plate 71 has a connecting ear plate 73 fixedly mounted on its bottom surface near the edge of one side of the workbench 1;

[0134] The connecting ear plate 73 is fixedly assembled to the upper edge of the outer wall of the end face of the workbench 1 on the same side by bolts;

[0135] A cooling fan 72 is embedded in the strip-shaped mounting plate 71 along its length, with its wind output end facing the workbench 1 .

[0136] Specifically in this embodiment, the plurality of cooling fans 72 are electrically connected to the controller, and the controller controls whether the cooling fans 72 are working or not;

[0137] Furthermore, the cooling fans 72 are selected according to the length of the workbench 1. In this embodiment, the length of the workbench 1 is three meters, and the wind strength of the cooling fans 72 on both sides is selected to blow the debris on the surface of the workbench 1 inward by 1-1.5 meters.

[0138] More specifically, the cooling fans 72 on both sides are controlled by the controller to work together, and the wind forces meet in the middle of the upper surface of the workbench 1. When the wind forces reach this point, they have weakened to some extent. After the wind forces meet and cancel each other out, the debris carried by the fans falls due to gravity, and some of the debris falls directly into the strip window 8. The debris that does not fall into the strip window 8 is swept into the strip window 8 by an external cleaning tool.

[0139] It can be understood that the debris swept by the cooling fan 72 is mainly the debris that falls on the surface of the workbench 1. During the cutting process of the plate and the process of removing the workbench 1 after cutting, the cooling fan 72 can also remove some of the debris adhering to the outer wall of the plate and cool the plate by air.

[0140] In some embodiments, a plate support structure 9 is installed between the strip window 8 and the upper surface of the workbench 1, which includes:

[0141] The upper end of the inner wall of the strip window 8 is rotated in the length direction with a bidirectional screw rod 93;

[0142] A driving motor 92 is fixedly mounted on the outer wall of the workbench 1 at the end of the bidirectional screw rod 93, and its output end passes through the outer wall of the strip-shaped window 8 and is fixedly connected to the end of the bidirectional screw rod 93 on the same side;

[0143] The outer wall of the bidirectional screw rod 93 is symmetrically screwed with mounting sliders 94 at both ends, which slide and fit with the inner wall of the strip window 8;

[0144] A transverse support plate 91 is fixedly mounted on the upper end of the mounting slide 94 .

[0145] Specifically in this embodiment, the bidirectional screw rod 93 is a conventional technology, and the threads on the front and rear sides of the screw rod are in opposite directions. The drive motor 92 is energized to drive the bidirectional screw rod 93 to rotate, driving the front and rear mounting sliders 94 to move toward or in opposite directions, thereby driving the transverse support plate 91 fixed at the upper end of the mounting slider 94 to move toward or in opposite directions. By adjusting the distance between the front and rear transverse support plates 91, plates of different sizes can be supported within a certain range.

[0146] Furthermore, the transverse support plate 91 is specifically a horizontally arranged strip-shaped rectangular shell, the interior of the strip-shaped rectangular shell is a cavity, and the top surface of the strip-shaped rectangular shell is uniformly provided with through holes along the length direction. The left side of the strip-shaped rectangular shell is fixedly connected to an exhaust pipe, and the exhaust pipe is connected to an external vacuum pump. The negative pressure suction force generated at the through hole adsorbs and fixes the plate placed on the top surface of the front and rear transverse support plates 91;

[0147] It can be understood that after the front and rear transverse support plates 91 are manufactured, the height of the plate is higher than the height of the tabletop blowing mechanism 7, and the wind force acting on the plate is located at the bottom surface of the plate.

[0148] In some embodiments, the arched lifting frame 3 includes:

[0149] The connecting block 32 is symmetrically fixed to the front wall of the workbench 1 by bolts;

[0150] The second electric push rod 31 is fixedly mounted on the upper end of the connecting block 32;

[0151] A linear module 33 is fixedly mounted on the upper end of the front and rear second electric push rods 31, and a slider is provided on the bottom surface of the linear module 33;

[0152] The linear module 33 is arranged along the width direction of the workbench 1 and is located directly above the workbench 1;

[0153] The upper end of the lifting and cutting mechanism 4 is fixedly connected to the bottom surface of the slider of the linear module 33;

[0154] The cutting head of the lifting and cutting mechanism 4 is arranged horizontally.

[0155] Specifically in this embodiment, the second electric push rod 31 is connected to the controller, and the controller controls the extension and contraction amount of the second electric push rod 31, thereby controlling the height of the lifting and cutting mechanism 4;

[0156] Furthermore, the linear module 33 can drive the lowering and cutting mechanism 4 to move forward and backward. Due to the limitation of the forward and backward movement distance of the linear module 33, this solution is suitable for the case where the length of the cut plate in the width direction of the workbench 1 is limited. The length of the cut plate in the width direction of the workbench 1 will not exceed the width of the workbench 1.

[0157] It is understandable that if the length of the plate to be cut is long in the width direction of the workbench 1 and the rear end extends a long distance beyond the rear side transverse support plate 91, auxiliary support can be provided at the rear end of the plate, and the support surface needs to be flat.

[0158] In some embodiments, the descending cutting mechanism 4 includes a third electric push rod 41, the upper end of which is fixed to the bottom surface of the lower end slider of the linear module 33, and a disc cutter 42 is fixed to the telescopic lower end of the third electric push rod 41. The cutting head is disc-shaped and can be replaced. When necessary, a head with a larger outer diameter can be replaced.

[0159] The third electric push rod 41 is connected to the controller to control the extension and contraction amount, and cooperates with the extension and contraction of the second electric push rod 31 to perform multi-level lifting control on the position of the disc cutter 42, and flexibly adjust the height of the disc cutter 42.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
