Description

Technical Field

[0001] The invention relates to a metal cutting device for making an advertisement board, belonging to the technical field of metal cutting. Background Art

[0002] Billboards refer to all outdoor media that convey advertising information. They are also a signal tool in the pulling system to start the next production process or transport the finished product to the downstream process. The materials of billboards are generally: stainless steel plates and aluminum-plastic plates, etc. In the billboard production process, they need to be cut manually or mechanically. When stainless steel plates and other metal plates are used to make billboards, metal cutting machines are generally used to cut information fonts on the metal plates to complete the production of billboards. When using the current metal cutting machine, the metal plate is generally placed on a platform with a mesh inside the metal cutting machine, and then the metal plate is cut using the laser cutting module on the metal cutting machine. However, the waste generated during the cutting process is easily lifted by the platform and cannot be separated from the metal plate, resulting in a high probability of jamming between the cutting waste and the billboard, leading to a high probability of danger to the workers due to factors such as waste falling during the subsequent material retrieval process. At the same time, when removing the waste in the billboard that is stuck or in a state of material jamming after material retrieval, there is a high probability that the billboard will be deformed due to manual operation, which will affect the metal cutting effect and quality.

The plurality of iron rods 91 are used in combination to lift the guide plate 6 on the one hand and guide the magnetism generated by the large electromagnet 9 into the guide plate 6 on the other hand. A plurality of through holes 62 penetrating the guide plate 6 are formed on the upper end surface of the guide plate 6 and are recessed downward. The ejector rod 7 penetrates the guide plate 6 through the through holes 62. A plurality of straight tubes 71 alternately arranged with the iron rods 91 and located on the lower side of the guide plate 6 are evenly arranged on the upper end of the mounting plate 92. The straight tubes 71 are used to provide installation space for components such as the movable plate 75. The plurality of movable plates 75 are respectively slidably connected in the plurality of straight tubes 71. The ejector rod 7 is lifted through the movable plate 75. A mounting carrier is provided, and a plurality of top rods 7 whose upper ends extend out of the upper side of the straight tube 71 and penetrate the through hole 62 are respectively mounted on the middle part of the upper end of a plurality of movable plates 75. The plurality of top rods 7 are used in combination to lift the raw material plate of the billboard, and the top rods 7 are made of plastic components. The lower end surfaces of the plurality of movable plates 75 are recessed upward to form mounting grooves 73. The mounting grooves 73 provide mounting space for the magnetic block 74.

The annular plate 77 located in the straight tube 71 is slidably connected to the outer end of the ejector rod 7, and the elastic member 76 is installed to limit the position through the annular plate 77, and the elastic member 76 located on the outer side of the ejector rod 7 is arranged between the annular plate 77 and the movable plate 75, and the movable plate 75 is moved downward by the elastic member 76. The elastic member 76 can be a spring, and the inner wall surface of the straight tube 71 is recessed outward to form a slot, and the slot is used to provide an installation space for the limiter, and then the limiter located on the outer side of the ejector rod 7 and attached to the upper end of the annular plate 77 is assembled to the slot, and the annular plate 77 is limited to be installed by the limiter, and the limiter can be a retaining spring 78; The cover plate 13 is hinged to the upper end of the shell 1 through a hinge, and the opening of the shell 1 is blocked by the cover plate 13. The movable parts of the two second telescopic devices, which are arranged obliquely with the left side higher than the right side and the fixed parts installed on the upper end of the shell 1, are both movably arranged on the right end of the cover plate 13. The two second telescopic devices are used in conjunction with each other to automatically open and close the cover plate 13. A through groove penetrating the cover plate 13 is formed on the right end surface of the cover plate 13, which is concave to the left. The through groove provides an installation space for the transparent plate, and then the transparent plate located between the two second telescopic devices is arranged in the through groove. Through the transparent plate, it is convenient to observe the situation in the cutting process in the shell 1 in real time; A vertical plate 61 with a mounting plate 92 and a large electromagnet 9 at the right end and the other end disposed at the lower end of the guide plate 6 is installed on the bottom end of the inner part of the shell 1. The installation position of the collection drawer 11 is limited by the vertical plate 61, and the collection drawer 11 extending to the left end of the shell 1 and located at the lower side of the guide plate 6 is attached to the left end of the vertical plate 61. The collection drawer 11 is used to collect waste chips.

[0020] Before use, first connect the circuit of the small electromagnets 72 of appropriate number and appropriate position, so that the corresponding small electromagnets 72 generate magnetism. Since the small electromagnets 72 and the magnetic blocks 74 are arranged to repel each other, a repulsive force is generated between the corresponding small electromagnets 72 and the magnetic blocks 74. Under the action of the repulsive force, the corresponding movable plate 75 moves upward along the straight tube 71, thereby compressing the elastic member 76, so that the elastic member 76 generates elastic force, and the upward movement of the movable plate 75 causes the top rods 7 of appropriate number and appropriate position to move upward, and then the billboard raw material plate is placed in the shell 1, and the multiple top rods 7 are used to lift the billboard raw material plate, and then the circuit of the large electromagnet 9 is connected, so that the large electromagnet 9 generates magnetism, and the multiple iron rods 91 introduce the magnetism generated by the large electromagnet 9 into the guide plate 6, thereby forming magnetism on the guide plate 6, and then the two first electric push rods 12 are started, so that the cover plate 13 performs a mechanical closing movement, and then the cover plate 13 is moved into the opening of the shell 1; Then start the first motor 22, the second motor 33 and the laser cutting head 8. The first motor 22 drives the corresponding first gear 23 to rotate, and with the assistance of the synchronous belt, the other first gear 23 rotates, thereby causing the two first screw rods 21 to rotate synchronously. Since the two first screw rods 21 are connected to the U-shaped frame 3 through a ball nut pair, the two first screw rods 21 rotate synchronously and simultaneously cause the U-shaped frame 3, the nut seat 32 and the laser cutting head 8 to move left and right. The second motor 33 drives the second screw rod 31 to rotate. Since the second screw rod 31 is connected to the nut seat 32 through a ball nut pair, the rotation of the second screw rod 31 simultaneously causes the nut seat 32 and the laser cutting head 8 to move forward and backward. At this time, the working laser cutting head 8 performs metal cutting operation on the billboard raw material plate, thereby making the billboard raw material plate into a billboard. During the metal cutting process, the magnetism on the guide plate 6 will exert an adsorption force on the billboard raw material plate, so as to achieve stable placement of the billboard raw material plate, effectively reduce the probability of the billboard raw material plate sliding during cutting, effectively ensure the metal cutting effect, and effectively ensure the quality of the produced billboard. When waste is generated by cutting, the magnetism on the guide plate 6 will still exert an adsorption force on the waste, and under the action of the adsorption force, the waste will move down and contact the guide plate 6, so that the waste and the billboard can be separated in time, effectively reducing the probability of material jamming between the cutting waste and the billboard, effectively reducing the probability of deformation of the billboard due to subsequent waste discharge operations, effectively reducing the probability of danger to the staff, and effectively ensuring the metal cutting effect and quality; After the billboard raw material plate is made into a billboard, the laser cutting head 8 is first moved to the original position by using the first screw rod 21, the first motor 22, the first gear 23, the synchronous belt, the second screw rod 31, the nut seat 32 and the second motor 33, and then the cover plate 13 is opened by the two first electric push rods 12, and then the circuit of the large electromagnet 9 is disconnected, so that the magnetism on the guide plate 6 disappears, and then the billboard is taken out of the housing 1, and then the circuit of the small electromagnet 72 is disconnected, so that the repulsive force between the small electromagnet 72 and the magnetic block 74 is made, and Under the elastic force of the elastic member 76, the movable plate 75 and the push rod 7 move down back to their original positions. At this time, the upper end surfaces of the plurality of push rods 7 overlap with the upper end surfaces of the guide plate 6. Since the guide plate 6 is tilted with the left side lower and the right side higher, the waste on the guide plate 6 will slide to the left along the guide plate 6 and fall into the collection drawer 11, so that the waste generated by cutting can be discharged in time, effectively reducing the probability of waste accumulation on the guide plate 6, and effectively reducing the probability of subsequent billboard raw material plates being lifted up due to factors such as accumulation, thereby effectively ensuring the metal cutting effect.

[0021] Embodiment 2: A large electromagnet 9, a plurality of iron rods 91 and a guide plate 6 are used to adsorb the waste generated by cutting, so that the waste can be separated from the billboard in time. In order to avoid the phenomenon of gaps at the outer end of the billboard, surplus material is generally left during the manufacture of the billboard raw material plate, and metal cutting is generally performed on the edge of the outer end of the billboard during production, thereby forming frame-type waste at the edge of the outer end of the billboard. However, the adsorption force exerted by the magnetism on the guide plate 6 on the frame-type waste can easily make it impossible to separate the frame-type waste from the billboard, resulting in a high probability of jamming between the billboard and the frame-type waste located on the outside, resulting in the subsequent manual separation of the frame-type waste from the billboard, resulting in a high probability of deformation of the billboard due to waste discharge, which will affect the metal cutting effect and quality.

The first bevel gear 404 and the second bevel gear 434 are used in conjunction with each other to make the first shaft 403 and the second shaft 433 rotate synchronously, and then the rack 44 is arranged on the bottom end inside the groove 51, and the second gear 45 is rotated through the rack 44, and the second gear 45 located in the groove 51 and meshed with the upper end of the rack 44 is arranged on the front end of the second shaft 433, and the second shaft 433 is rotated through the second gear 45.

[0023] When in use, first use the small electromagnets 72, magnetic blocks 74 and movable plates 75 of appropriate number and position to move the push rods 7 of appropriate number and position upward, then put the billboard raw material board into the shell 1, and make the multiple push rods 7 lift the billboard raw material board, at this time, the rear end and the right end of the billboard raw material board are respectively fitted with the first limit box 4 and the second limit box 43, so as to realize the positioning and placement of the billboard raw material board, effectively reduce the probability of tilting of the metal cutting route on the billboard raw material board, effectively reduce the time of finding the original position in the subsequent metal cutting, and effectively ensure the metal cutting effect; Then, the first screw rod 21, the first motor 22, the first gear 23, the synchronous belt, the second screw rod 31, the nut seat 32, the second motor 33 and the laser cutting head 8 are used to perform metal cutting operations on the billboard raw material plate. After the billboard is made, the second electric push rod 42 is started to drive the first limit box 4 and the second limit box 43 to move to the left, thereby pushing the billboard to move to the left, realizing the mechanical discharging operation of the billboard, effectively reducing the probability of danger caused by taking materials, etc., with high safety, and effectively ensuring the metal cutting effect; When the second limit box 43 moves to the left, the second gear 45 will move to the left along the rack 44, and the second gear 45 will rotate, thereby rotating the second shaft 433, the second bevel gear 434 and the plurality of second cams 432. Since the second bevel gear 434 is meshed with the first bevel gear 404, the rotation of the second bevel gear 434 will rotate the first bevel gear 404, thereby rotating the first shaft 403 and the plurality of first cams 402. The raised portions of the plurality of rotating first cams 402 and the raised portions of the plurality of rotating second cams 432 will knock the frame-type waste located outside the billboard, thereby mechanically separating the billboard from the frame-type waste located outside, effectively reducing the probability of material jamming between the billboard and the frame-type waste located outside, and effectively reducing the probability of deformation of the billboard due to waste discharge, thereby effectively ensuring the metal cutting effect and quality. Embodiment 3: A large electromagnet 9, a plurality of iron rods 91 and a guide plate 6 are used to absorb the waste generated by cutting, so that the waste and the billboard can be separated in time. However, due to the design, some of the cut waste is in the shape of a gourd, etc., which causes one side of the waste to move down first and come into contact with the guide plate 6 when the waste is absorbed. As a result, the waste is prone to be in a warped state and penetrate the billboard, and there is a high probability of material jamming. As a result, when the billboard is subsequently mechanically discharged, obstruction is likely to occur between the warped and stuck waste and the top rod 7, resulting in a high probability that the billboard will be deformed due to mechanical discharge, which will affect the metal cutting effect and quality.

[0024] In order to solve the above problems, Figure 14-16 As shown, a main pipe 302 arranged along the length direction of the U-shaped frame 3 and located between the two limit frames 5 is installed on the lower end of the U-shaped frame 3. Through the main pipe 302, a mounting carrier is provided for components such as nozzles 303, and multiple nozzles 303 located on the upper side of the first limit box 4 and arranged obliquely with the left lower and the right higher are equidistantly connected and arranged on the lower end of the main pipe 302. Multiple nozzles 303 are used in combination to perform air blowing on the upper surface of the guide plate 6, and then a metal pipe 301 that penetrates the baffle 2 and extends out of the right side of the shell 1 and is respectively slidably connected to the baffle 2 and the shell 1 and is located between the two first gears 23 and on the inner side of the synchronous belt is connected and installed on the middle part of the right end of the main pipe 302. Gas is transported into the main pipe 302 through the metal pipe 301, and the other end of the metal pipe 301 is connected and arranged with the gas source equipment through a hose.

[0025] During the left-right movement of the U-shaped frame 3, the main pipe 302, the metal pipe 301 and the multiple nozzles 303 will move left-right. At the same time, the gas is transported to the metal pipe 301 through the gas source equipment, and the gas in the metal pipe 301 is transported to the main pipe 302, and then the gas in the main pipe 302 is diverted to the multiple nozzles 303, and then the gas is sprayed on the upper surface of the billboard raw material board to be cut through the multiple nozzles 303, so as to exert downward pressure on the upper surface of the waste generated by cutting, effectively reduce the probability of material jamming due to factors such as the warping of the waste, effectively reduce the probability of billboard formation during mechanical discharging, and effectively ensure the metal cutting effect and quality; After the billboard raw material plate is made into a billboard, the laser cutting head 8 is first moved to the original position by using the first screw rod 21, the first motor 22, the first gear 23, the synchronous belt, the second screw rod 31, the nut seat 32 and the second motor 33, and then the billboard is mechanically discharged by the first limit box 4, the second limit box 43 and the second electric push rod 42 and other components, and then the movable plate 75 and the push rod 7 are moved down back to the original position by using the elastic member 76. At this time, the upper end faces of the plurality of push rods 7 overlap with the upper end faces of the guide plate 6. Because the guide plate 6 is tilted and arranged with the left side lower and the right side higher, the waste on the guide plate 6 will slide to the left along the guide plate 6 and fall into the collection drawer 11; Then, the first motor 22, the two first gears 23, the synchronous belt and the two first screw rods 21 are used to move the U-shaped frame 3, the main pipe 302 and the multiple nozzles 303 to the left. At this time, the multiple nozzles 303 will blow air to the upper end of the guide plate 6, so that the waste slag on the guide plate 6 moves to the left along the guide plate 6 due to the blowing and falls into the collection drawer 11, so that the waste slag generated by cutting can be discharged in time, effectively reducing the probability of the waste slag hindering the discharge of subsequent waste materials, and effectively ensuring the metal cutting effect.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
