Description

Technical Field

[0001] The present invention belongs to the field of metal cutting equipment, and specifically relates to an automatic processing equipment for corner brackets used in wooden furniture. Background Art

[0002] Corner brackets are common connectors in wooden furniture, used to reinforce and fix various components of the furniture. Corner brackets are mainly used to connect and fix two mutually perpendicular members, enhancing the stability and load-bearing capacity of the furniture. Relatively larger wooden furniture requires larger corner brackets for connection. When processing such corner brackets, angle steel is usually cut to form corner brackets, and then the corner brackets are drilled and polished. After metal cutting processes such as drilling, cutting, and polishing, a complete connecting piece corner bracket can be initially formed.

[0003] A patent document with the publication number CN106736557B discloses a processing device for special-shaped movable corner brackets, including a workbench, an auxiliary clamp, a conveyor, a drilling mechanism, and a cutting machine. An auxiliary clamp is provided at one end of the workbench, a conveyor is provided on the workbench near the auxiliary clamp, a drilling mechanism is provided on the workbench near the conveyor, and a cutting machine is provided on one side of the workbench along the advancing direction of the special-shaped movable corner bracket profile near the drilling mechanism.

[0004] In the traditional technical solution, the production and processing of corner brackets require multiple devices to participate. After being processed by one device, it is then moved to another device for processing. Therefore, the production and processing efficiency of corner brackets is relatively slow. In the traditional technology, during the process of cutting and polishing angle steel to form corner brackets, the positions of the angle steel and the corner brackets need to be adjusted to cooperate with cutting and polishing and other cutting processes, and the adjustment means in the traditional technology are not precise enough.

[0005] Therefore, the present invention provides an automatic processing equipment for corner brackets used in wooden furniture. Summary of the Invention

[0009] Preferably, the punching component includes an electric drive motor and two punching moving heads movably installed at the end of the electric drive motor. There is a certain distance between the two punching moving heads. A fixed frame is fixedly installed on the side of the electric drive motor. One end of the fixed frame is fixedly connected to the upper part of the first conveyor table.

[0010] Preferably, a rotating table is rotatably installed on the side of the rotating component. The grinding wheel and the cutting knife are movably installed on the side of the rotating table. The rotating table is used for driving the grinding wheel and the cutting knife to rotate. The cutting knife is used for cutting the metal angle steels.

[0011] Preferably, a feeding groove is penetrated and opened inside the second material conveying block for placing the metal angle steels. Feeding grooves are penetrated and opened inside the first fixed block, the first material conveying block, and the second material conveying block. A plurality of component grooves are opened at the adjacent ends of the first material conveying block and the second material conveying block. The plurality of component grooves are symmetrically distributed inside the component grooves. The clamping and displacement components move inside the corresponding component grooves.

[0012] Preferably, an air pump is fixed on the outside of the second material conveying block. A plurality of air pipes are fixedly installed at the output end of the air pump. A fixed motor is also fixedly installed inside the second material conveying block. A screw rod is fixedly installed at the output end of the fixed motor. The screw rod is in screw connection with the clamping and displacement component. By rotating the screw rod, the clamping and displacement component is driven to move inside the component groove.

[0013] Preferably, the clamping displacement assembly includes a displacement column that moves inside the component groove and an air cylinder fixedly installed on one side of the displacement column. A moving cylinder is movably installed inside the air cylinder. The displacement column is helically connected to the screw rod. The air pump is connected to the inside of the air cylinder through the corresponding air pipe that penetrates the displacement column.

[0014] Preferably, a small column is fixedly installed at one end of the moving cylinder. An airbag ring is fixedly installed on the outer side of the small column. The airbag ring is connected to the air pump through an air pipe.

[0015] Preferably, a plurality of electric telescopic rods are fixedly installed on the outer side of one end of the air cylinder.

[0016] Preferably, a fitting ring is movably installed on the side of the covering component facing the small column.

The side of the fitting ring is connected to the inside of the moving ring through a plurality of springs.

[0017] The beneficial effects of the present invention are as follows: 1. For the automatic angle code processing equipment for wooden furniture of the present invention, the rotation of the rotating assembly drives the cutting tool to rotate. The cut metal angle steel forms an angle code. After the cutting of the metal angle steel is completed, the moving table moves between the second conveying table and the first conveying table to facilitate the subsequent grinding by the grinding wheel. The grinding wheel is driven to rotate by the rotating assembly and the grinding wheel rotates at a high speed. By the same method, the distance between the opposite cutting surfaces of the metal angle steel and the angle code is reduced. Moreover, the clamping displacement assembly arranged inside the second material feeding block and the first material feeding block can clamp and move the metal angle steel and the angle code, perform secondary movement, and accurately move the distance, so that the cutting and processing process of the angle code does not require multiple devices to participate, and the processing process of the angle code can be completed during the conveying process of the metal angle steel. And in this device, the clamping displacement assembly can drive the metal angle steel and the angle code to perform further precise movement to ensure the processing quality of the additional code.

[0018] 2. For the automatic angle code processing equipment for wooden furniture of the present invention, since two clamping displacement assemblies are also arranged inside the first material feeding block, the metal angle steel can also be driven to move inside the first material feeding block by the two clamping displacement assemblies. The distance between the cutting surfaces of the metal angle steel and the angle code can be initially adjusted by the movement of the moving table. Subsequently, by rotating the screw rod, the moving cylinder and the corresponding angle code or metal angle steel are driven to move for secondary precise adjustment, so that the cutting surfaces of the metal angle steel and the angle code are in the position to be ground outside the grinding wheel. When the metal angle steel is about to be cut, the moving cylinder is inside the corresponding angle code groove, which helps to correct the position of the metal angle steel to ensure the completion of the cutting work.

[0019] 3. An automatic processing device for corner codes used in wooden furniture according to the present invention has two airbag rings inside the corner code groove. Driven by an air pump, another air pipe delivers air into the airbag rings, causing the two airbag rings to expand. At this time, the expanded airbag rings are in close contact with the inner wall of the corner code groove, which can further accurately position the cutting surface of the corner code or metal angle steel. And when the grinding wheel grinds the cutting surface of the corner code or metal angle steel, the close contact between the expanded airbag rings and the corner code groove can reduce the vibration frequency and amplitude of the corner code or metal angle steel, thereby avoiding damage to the corner code or metal angle steel and the second and first material conveying blocks.

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Embodiment 1: As Figure 1-2 and Figure 6 shown, an automatic processing device for corner codes of wooden furniture according to an embodiment of the present invention includes an equipment workbench 1 and a metal angle steel 2 conveyed above the equipment workbench 1. Two punching components 3 are fixedly installed above the equipment workbench 1, and a rotating component 4 is also fixedly installed on the side of the punching component 3. A grinding wheel 5 and a cutting knife 6 are movably installed on one side of the rotating component 4. The rotating component 4, the grinding wheel 5 and the cutting knife 6 are located above the metal angle steel 2; The equipment workbench 1 includes a first conveying table 11 and a second conveying table 12. A moving table 13 is slidably installed between the first conveying table 11 and the second conveying table 12. A first fixing block 111 is fixedly installed above the first conveying table 11, a first material conveying block 131 is fixedly installed above the moving table 13, and a second material conveying block 121 is fixedly installed above the second conveying table 12. The first fixing block 111, the first material conveying block 131 and the second material conveying block 121 are used to convey the metal angle steel 2. After the metal angle steel 2 undergoes cutting work by the punching component 3, the cutting knife 6 and the grinding wheel 5, corner codes are formed. A plurality of corner code grooves 21 are penetrated and opened inside the metal angle steel 2; A plurality of symmetrically distributed clamping and displacement components 7 are movably installed inside the second material conveying block 121 and the first material conveying block 131. The plurality of clamping and displacement components 7 are symmetrically arranged in pairs and are on the same axis. The symmetrically arranged clamping and displacement components 7 are used to clamp the metal angle steel 2 and drive it to move.

[0025] Specifically, the metal angle steel 2 is conveyed above the equipment workbench 1 through the first fixing block 111, the second feeding block 121 and the first feeding block 131. The two punching components 3 are staggered, and one punching component 3 is arranged downward and one punching component 3 is arranged horizontally, so that the metal angle steel 2 during the conveying process can be punched to form the holes required for the corner brackets. The punched part of the metal angle steel 2 continues to be conveyed into the first feeding block 131 and the second feeding block 121. At this time, the rotation of the rotating component 4 drives the cutting knife 6 to rotate, that is, the cutting knife 6 rotating at high speed contacts the metal angle steel 2 between the second feeding block 121 and the first feeding block 131 and cuts it. The cut metal angle steel 2 forms corner brackets. After the cutting of the metal angle steel 2 is completed, the moving table 13 moves between the second conveying table 12 and the first conveying table 11, increasing the distance between the opposing cutting surfaces of the metal angle steel 2 and the corner brackets at this time, so as to facilitate the subsequent grinding by the grinding wheel 5. The grinding wheel 5 is driven to rotate by the rotating component 4 and the grinding wheel 5 rotates at high speed, so that the grinding wheel 5 rotating at high speed is located between the second feeding block 121 and the first feeding block 131. By the same method, the distance between the opposing cutting surfaces of the metal angle steel 2 and the corner brackets is reduced, and the clamping and displacement component 7 arranged inside the second feeding block 121 and the first feeding block 131 can clamp and move the metal angle steel 2 and the corner brackets, perform secondary movement, and accurately move the distance, so that the opposing cutting surfaces of the metal angle steel 2 and the corner brackets are abutted against the outside of the grinding wheel 5. At this time, the grinding wheel 5 can grind the opposing cutting surfaces of the metal angle steel 2 and the corner brackets. At this time, the corner brackets located inside the second feeding block 121 are processed and formed. In this device, by setting the punching component 3 and the integrated grinding wheel 5 and cutting knife 6, the cutting process of the corner brackets does not require multiple devices to participate, and the processing process of the corner brackets can be completed during the conveying process of the metal angle steel 2. And in this device, the clamping and displacement component 7 can drive the metal angle steel 2 and the corner brackets to perform further precise movement to ensure the processing quality of the corner brackets.

[0026] As Figure 2-3 shown, a working groove 112 is formed through the upper position of the first conveying table 11, and the punching positions of the two punching components 3 are inside the working groove 112. A second fixing block 113 is also fixedly installed above the first conveying table 11. The second fixing block 113 and the first fixing block 111 are made of the same structure.

[0027] Specifically, when the two punching components 3 punch the metal angle steel 2, the waste materials punched down will fall from the working groove 112, which will not affect the subsequent conveying of the metal angle steel 2 and the punching of the punching components 3. The setting of the second fixing block 113 is to stabilize the conveying of the metal angle steel 2, and the function of the second fixing block 113 is the same as that of the first fixing block 111.

[0028] As Figure 4-5As shown, the punching assembly 3 includes an electric drive machine 33 and two punching movable heads 31 movably installed at the end of the electric drive machine 33. There is a certain distance between the two punching movable heads 31. A fixing frame 32 is fixedly installed on the side of the electric drive machine 33, and one end of the fixing frame 32 is fixedly connected to the top of the conveying platform 11.

[0029] A rotating table 41 is rotatably installed on the side of the rotating component 4, and a grinding wheel 5 and a cutting knife 6 are movably installed on the side of the rotating table 41. The rotating table 41 is used to drive the grinding wheel 5 and the cutting knife 6 to rotate. The cutting knife 6 is used to cut the metal angle steel 2, and the grinding wheel 5 is used to grind the metal angle steel 2.

[0030] Specifically, the two punching moving heads 31 provided in the same punching assembly 3 are on the same axis. After the metal angle steel 2 is punched by the two punching assemblies 3, the vertical and horizontal surfaces of the subsequent angle codes will be provided with angle code grooves 21 to facilitate the subsequent use of the angle codes. Driven by the electric drive motor 33, the punching moving head 31 can move toward the position of the metal angle steel 2 to complete the punching step. When the rotating table 41 rotates, it can drive the grinding wheel 5 and the cutting knife 6 to move as a whole, thereby moving the grinding wheel 5 and the cutting knife 6 to the position between the angle codes of the metal angle steel 2.

[0031] like Figure 6 As shown, a discharge trough 1211 is provided inside the second feed block 121 for placing the metal angle steel 2, and a discharge trough 1211 is provided inside the fixed block 111, the first feed block 131 and the second feed block 121, and a plurality of component grooves 1212 are provided at the ends adjacent to the first feed block 131 and the second feed block 121, and the plurality of component grooves 1212 are symmetrically distributed inside the component grooves 1212, and the clamping displacement assembly 7 moves inside the corresponding component grooves 1212.

[0032] As shown Figure 7 and Figure 9 As shown, an air pump 1213 is fixed to the outside of the second feed block 121, and a plurality of air pipes 1214 are fixedly installed at the output end of the air pump 1213. A fixed motor 1215 is also fixedly installed inside the second feed block 121, and a screw 1216 is fixedly installed at the output end of the fixed motor 1215. The screw 1216 is spirally connected to the clamping displacement assembly 7, and the rotation of the screw 1216 drives the clamping displacement assembly 7 to move inside the component groove 1212.

[0033] The clamping displacement assembly 7 includes a displacement column 71 movable inside the component groove 1212 and an air cylinder 72 fixedly installed on one side of the displacement column 71, a moving cylinder 74 is movably installed inside the air cylinder 72, the displacement column 71 is spirally connected to the screw 1216, and the air pump 1213 is connected to the interior of the displacement column 71 and the air cylinder 72 through the corresponding air pipe 1214.

[0034] Specifically, the fixed motor 1215 drives the screw 1216 to rotate, which can cause the clamping displacement assembly 7 stuck inside the component groove 1212 to move. After the metal angle steel 2 is cut, the corner code with an unpolished cutting surface is in the feeding groove 1211 at this time, and the moving cylinder 74 and the corresponding corner code groove 21 are on the same axis. In the initial state, the moving cylinder 74 is hidden inside the component groove 1212, which does not affect the movement of the corner code inside the feeding groove 1211. At this time, the air pump 1213 is driven to introduce air into the air cylinder 72 through a group of air pipes 1214, so that the moving cylinder 74 moves inside the air cylinder 72 until the moving cylinder 74 moves into the corner code groove 21. The clamping displacement assemblies 7 are symmetrically distributed and on the same axis. Therefore, through the same process, both moving cylinders 74 will be inside the corner code groove 21. At this time, the movement of the displacement column 71 drives the moving cylinder 74 and the corner code to move. There are also two clamping displacement assemblies 7 inside the first feeding block 131. Therefore, the metal angle steel 2 can also be driven to move inside the first feeding block 131 by the two clamping displacement assemblies 7. The distance between the metal angle steel 2 and the cutting surface of the corner code can be initially adjusted by the movement of the moving table 13. Subsequently, the rotation of the screw 1216 drives the moving cylinder 74 and the corresponding corner code or metal angle steel 2 to move for secondary precise adjustment, so that the metal angle steel 2 and the cutting surface of the corner code are at the position to be polished outside the grinding wheel 5. When the metal angle steel 2 is about to be cut, the moving cylinder 74 is inside the corresponding corner code groove 21, which helps to correct the position of the metal angle steel 2 to ensure the completion of the cutting work.

[0035] As Figure 8 shown, a small column 741 is fixedly installed at one end of the moving cylinder 74, and an airbag ring 742 is fixedly installed on the outside of the small column 741. The airbag ring 742 is connected to the air pump 1213 through the air pipe 1214.

[0036] Specifically, when the end of the moving cylinder 74 moves into the corner code groove 21, the airbag ring 742 is inside the corner code groove 21 and in contact at this time. Due to the opposite setting of the clamping displacement assemblies 7, that is, the two airbag rings 742 are inside the corner code groove 21. The air pump 1213 drives the other air pipe 1214 to transport air into the airbag ring 742, so that the two airbag rings 742 are in an inflated state. At this time, the inflated airbag ring 742 is in close contact with the inner wall of the corner code groove 21, which can further accurately position the cutting surface of the corner code or metal angle steel 2. And when the grinding wheel 5 grinds the cutting surface of the corner code or metal angle steel 2, the close contact between the inflated airbag ring 742 and the corner code groove 21 can reduce the vibration frequency and amplitude of the corner code or metal angle steel 2, thereby avoiding damage to the corner code or metal angle steel 2 and the second feeding block 121 and the first feeding block 131.

[0037] Embodiment 2: As Figure 7-8As shown, compared with the first comparative example, another implementation manner of the present invention is as follows: A plurality of electric telescopic rods 73 are fixedly installed on the outer side of one end of the air cylinder 72. A covering member 75 is movably sleeved on the outer side of the moving cylinder 74. One ends of the plurality of electric telescopic rods 73 are connected to the covering member 75. A fitting ring 752 is movably installed on the side of the covering member 75 facing the small column 741. The diameter of the fitting ring 752 is larger than the inner diameter of the moving ring 751 and smaller than the outer diameter of the moving ring 751. The side of the fitting ring 752 is connected to the inside of the moving ring 751 through a plurality of springs.

[0038] Specifically, when the two airbag rings 742 are inside the corner code groove 21 and in contact, at this time, the two covering members 75 are outside the corner code groove 21, that is, inside the member groove 1212. When cutting is performed by the cutting knife 6, the driving electric telescopic rod 73 extends, thereby driving the covering member 75 to move outside the moving cylinder 74 until the covering member 75 contacts the outside of the metal angle steel 2. At this time, the whole fitting ring 752 slides inside the moving ring 751, and multiple springs between the moving ring 751 and the fitting ring 752 are compressed, that is, the two moving rings 751 cover the outside of the corner code groove 21. At this time, a sealed environment is formed inside the corner code groove 21. At this time, the two airbag rings 742 expand in this sealed environment, so that the airbag rings 742 can be in complete contact with the inner wall of the corner code groove 21, thereby further accurately positioning the processing position of the metal angle steel 2 or the corner code. During the cutting operation, the expanded airbag rings 742 can decompose some of the vibration force of the metal angle steel 2 or the corner code, reducing damage. When grinding is performed by the grinding wheel 5, the movement of the moving cylinder 74 can drive the movement of the metal angle steel 2 to further accurately position the processing position of the cutting surface of the metal angle steel 2 or the corner code. At this time, the electric telescopic rod 73 is contracted by electric drive, that is, the two covering members 75 move in the opposite direction, increasing the distance between the two moving rings 751 and the metal angle steel 2. At this time, the fitting ring 752 moves inside the moving ring 751 toward the outside of the metal angle steel 2 until one side of the fitting ring 752 abuts against the outside of the metal angle steel 2. At this time, the corner code groove 21 is also a sealed space, but the sealed space at this time is larger than before. Therefore, the gas inside the two airbag rings 742 inside the corner code groove 21 can expand toward the horizontal position, that is, the gas density of the airbag rings 742 is reduced at this time. When the metal angle steel 2 and the cutting surface of the corner code are abutted against the outside of the grinding wheel 5 by moving, the airbag rings 742 inside the corner code groove 21 are slightly compressed. The cutting surfaces of the metal angle steel 2 and the corner code are usually rough and uneven. At this time, the rough and uneven cutting surface will abut against the rotating outside of the grinding wheel 5. When the grinding wheel 5 rotates at a high speed, it will quickly grind off the rough and uneven cutting surface. At this time, the airbag rings 742 are not slightly compressed, so that the cutting surface of the metal angle steel 2 or the corner code is slightly close to the rotating outside of the grinding wheel 5, and the relatively flat cutting surface at this time is ground, thereby ensuring that the cutting surface is flat and smooth after being ground, which is beneficial to improving the quality of the corner code. In the traditional technology, to achieve this slight movement of the grinding distance, very complex machinery is required, and these very complex structures are extremely prone to damage if they are subjected to long-term vibrations such as cutting and grinding. The structure in this device can effectively avoid this problem.

[0039] Working principle: The metal angle steel 2 is conveyed above the equipment workbench 1 through the first fixing block 111, the second feeding block 121 and the first feeding block 131. The two punching components 3 are staggered, and one punching component 3 is arranged downward and one punching component 3 is arranged horizontally, so that the metal angle steel 2 during conveying can be punched to form the holes required for the angle code. The part of the metal angle steel 2 after punching continues to be conveyed into the first feeding block 131 and the second feeding block 121. At this time, the rotation of the rotating component 4 drives the cutting knife 6 to rotate, that is, the cutting knife 6 rotating at high speed and self-rotating contacts the metal angle steel 2 between the second feeding block 121 and the first feeding block 131 and cuts it. The cut metal angle steel 2 forms an angle code. After the cutting of the metal angle steel 2 is completed, the moving table 13 moves between the second conveying table 12 and the first conveying table 11 to increase the distance between the opposing cutting surfaces of the metal angle steel 2 and the angle code at this time, so as to facilitate the subsequent grinding by the grinding wheel 5. The grinding wheel 5 is driven to rotate by the rotating component 4 and the grinding wheel 5 rotates at high speed and self-rotates, so that the grinding wheel 5 rotating at high speed and self-rotating is located between the second feeding block 121 and the first feeding block 131. By the same method, the distance between the opposing cutting surfaces of the metal angle steel 2 and the angle code is reduced, and the clamping displacement component 7 arranged inside the second feeding block 121 and the first feeding block 131 can clamp and move the metal angle steel 2 and the angle code for secondary movement to accurately move the distance, so that the opposing cutting surfaces of the metal angle steel 2 and the angle code are against the outside of the grinding wheel 5. At this time, the grinding wheel 5 can grind the opposing cutting surfaces of the metal angle steel 2 and the angle code. At this time, the angle code inside the second feeding block 121 is processed and formed. In this device, by setting the punching component 3 and the integrated grinding wheel 5 and cutting knife 6, the cutting process of the angle code does not require multiple devices to participate, and the processing process of the angle code can be completed during the conveying of the metal angle steel 2. And in this device, the clamping displacement component 7 can drive the metal angle steel 2 and the angle code to make further precise movement to ensure the processing quality of the additional code. When the two airbag rings 742 are inside the angle code groove 21 and in contact, at this time the two covering members 75 are outside the angle code groove 21, that is, inside the member groove 1212. When cutting with the cutting knife 6, the driving electric telescopic rod 73 extends out and drives the covering member 75 to move outside the moving cylinder 74 until the covering member 75 contacts the outside of the metal angle steel 2. At this time, the whole fitting ring 752 slides inside the moving ring 751, and the multiple springs between the moving ring 751 and the fitting ring 752 are compressed, that is, the two moving rings 751 cover the outside of the angle code groove 21. At this time, a sealed environment is formed inside the angle code groove 21. At this time, the two airbag rings 742 expand in this sealed environment, which can make the airbag rings 742 completely contact the inner wall of the angle code groove 21, and further accurately position the processing position of the metal angle steel 2 or the angle code. During the cutting work, the expanding airbag rings 742 can decompose some of the vibration force of the metal angle steel 2 or the angle code and reduce the damage. When grinding with the grinding wheel 5,The movement of the cylinder 74 can drive the movement of the metal angle steel 2, further accurately positioning the processing position of the metal angle steel 2 or the cutting surface of the angle code. At this time, the electric telescopic rod 73 contracts by electric drive, that is, the two covering members 75 move in opposite directions, increasing the distance between the two moving rings 751 and the metal angle steel 2. At this time, the fitting ring 752 moves towards the outside of the metal angle steel 2 inside the moving ring 751 until one side of the fitting ring 752 abuts against the outside of the metal angle steel 2. At this time, the angle code groove 21 is also a sealed space, but the sealed space at this time is larger than before. Therefore, the gas inside the two airbag rings 742 inside the angle code groove 21 can expand towards the horizontal position, that is, the gas density of the airbag ring 742 is reduced at this time. When the metal angle steel 2 and the cutting surface of the angle code are abutted against the outer side of the grinding wheel 5 by moving, the airbag ring 742 inside the angle code groove 21 is slightly compressed. The cutting surfaces of the metal angle steel 2 and the angle code are usually rough and uneven. At this time, the rough and uneven cutting surface will abut against the rotating outer side of the grinding wheel 5. The high-speed rotation of the grinding wheel 5 will quickly grind off the rough and uneven cutting surface. At this time, the airbag ring 742 is not slightly compressed, so that the cutting surface of the metal angle steel 2 or the angle code approaches the rotating outer side of the grinding wheel 5 slightly, and the relatively flat cutting surface at this time is ground, so as to ensure that the cutting surface is flat and smooth after being ground, which is beneficial to improving the quality of the angle code. In the traditional technology, to achieve this slight movement of the grinding distance, very complex machinery is required, and these very complex structures are extremely easy to be damaged if they are subjected to long-term vibrations such as cutting and grinding. However, the structure in this device can effectively avoid this problem.
