Description

Technical Field

[0001] The invention relates to the field of steel plate production and processing, and more specifically to a CNC plate bending machine processing platform for steel plate production and processing. Background Art

[0002] Steel plate production and processing refers to the process of converting steel plate raw materials into finished or semi-finished products of various shapes and sizes. Steel plate production and processing includes five main steps: raw material preparation, forming, welding, surface treatment and heat treatment. The forming process in steel plate production and processing refers to the process of plastically deforming the steel plate through various processing methods to achieve the desired shape and size. In this step, the most commonly used operation is to use a bending machine to bend the steel plate into the desired shape.

[0003] The existing operation of bending steel plates adopts CNC sheet metal bending machines for bending. First, a fixed platform of appropriate size needs to be selected according to the thickness of the plate. The technician manually holds the steel plate and uses the steel plate to adjust the distance between the rulers. Then the technician steps on the button at the foot to make the bending knife bend the steel plate on the fixed platform, and then measures the bending angle to determine whether the bending angle meets the standard. If it is not standard, the CNC center is used to adjust the data until the bent steel plate meets the requirements, and then the workers perform batch bending operations on the steel plates. When the bending machine in the above-mentioned prior art performs bending work, since the workers do not have the technicians' understanding of the bending machine, the workers cannot correctly grasp the distance between the rulers, resulting in the workers habitually adjusting the distance between the rulers by hand. At this time, the workers step on the button for controlling the downward pressure of the bending knife due to operating errors or external influences, and the bending knife of the bending machine will press down and injure the worker's arm, causing damage to the worker's safety. The safety of the worker's working environment cannot be guaranteed to a certain extent, which leads to the occurrence of dangerous accidents. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 9 A processing platform of a CNC sheet metal bending machine for steel plate production and processing includes a bending machine body 1, the bending machine body 1 includes a bending mechanism 11 slidably mounted on the bending machine body 1, a bending tool head 14 is fixedly mounted on the bending mechanism 11, a processing platform body 12 is arranged on the bending machine body 1, a steel plate 13 can be placed on the processing platform body 12, the bending tool head 14 can be moved up and down by the bending machine and bend the steel plate 13, an auxiliary component 2 is arranged on the bending machine body 1, the auxiliary component 2 can limit the steel plate 13, and the auxiliary component 2 includes An electric slide rail 26 is fixedly installed on the outer surface of the bending machine body 1, and two groups of electric sliders 27 are matched on the electric slide rail 26. A stopper 21 is fixedly installed on the bottom of each electric slider 27, and a baffle 24 is fixedly installed on each stopper 21. A telescopic rod 25 is fixedly installed on the outer end of the electric slide rail 26, and a thrust spring 23 is sleeved on the outer surface of the telescopic rod 25. The top of the thrust spring 23 is fixedly connected to the outer end of the electric slide rail 26, and the bottom of the thrust spring 23 is fixedly connected to the pressure block 22, and the telescopic end of the telescopic rod 25 is fixedly connected to the pressure block 22.

[0032] The two groups of electric sliders 27 are symmetrically arranged on the left and right, and the stopper 21 is L-shaped. The two groups of stoppers 21 can be used together to limit the steel plate 13. The pressure block 22 is used in conjunction with the stopper 21. The thrust spring 23 and the telescopic rod 25 will not hinder the movement of the electric slider 27. The two groups of electric sliders 27 can move away from or approach each other under the action of the electric guide rail.

[0033] The bottom edges of the front and inner sides of each pressing block 22 are rounded, and the bottom of the pressing block 22 is frosted.

[0034] The bottom of the pressing block 22 can contact the stopper 21 under the action of the thrust spring 23 , and the horizontal height of the bend of the stopper 21 is the same as the horizontal height of the processing platform body 12 .

[0035] When using the bending machine body 1 to bend the steel plate 13, the staff first holds the outer end of the steel plate 13 and places the steel plate 13 horizontally on the processing platform body 12. At this time, the main control display station starts the electric slide rail 26 and brings the two electric sliders 27 closer to each other, so that the two stoppers 21 are closer to each other, and the steel plate 13 is clamped by the two baffles 24. Since the bottom edges of the front and inner sides of each pressing block 22 are rounded, the steel plate 13 will be clamped by the two stoppers 21. The part with rounded corners on the inner side of the pressing block 22 makes the two pressing blocks 22 move up, and the thrust is The spring 23 contracts and is in a compressed state (the compressed thrust spring 23 here will push the pressure block 22 downward, so that the pressure block 22 clamps and fixes one side of the steel plate 13), the telescopic rod 25 contracts, and then the staff pushes the steel plate 13 to the inside of the two stoppers 21 until the steel plate 13 is completely in contact with the inside of the stoppers 21. At this time, the staff steps on the button for starting the bending mechanism 11, so that the bending mechanism 11 moves downward with the bending cutter head 14, and performs a bending action on the steel plate 13 on the processing platform body 12, thereby realizing the bending action of the bending machine body 1 on the steel plate 13 on the processing platform body 12;

[0036] When the two stoppers 21 clamp the steel plate 13, under the action of the pressure block 22 and the stopper 21, the end of the steel plate 13 away from the staff is fixed by the pressure block 22 and the stopper 21, and at the same time, the two side surfaces of the steel plate 13 can be limited in position with the two baffles 24, thereby reducing the offset rotation of the steel plate 13 during bending, so as to achieve the effect of the same bending angle at both ends of the steel plate 13. Electric slide rails 26 and electric sliders 27 are added to the two stoppers 21, so that the staff no longer need to adjust the distance between the two stoppers 21 through the steel plate 13. Even if the staff makes an operating error and causes the bending blade 14 to bend the steel plate 13, the bending blade 14 will not press the staff's arm.

[0037] The bottom of the pressing block 22 is frosted to reduce the possibility that the pressing block 22 fixes the steel plate 13 and the steel plate 13 slips when being bent;

[0038] It should be noted that the bending machine body 1 has a foot-operated structure to control the bending mechanism 11 to carry the bending cutter head 14 to perform bending actions. This is a mature technology that is integrated into the existing bending machine. It is briefly mentioned in the manual. Figures 1 to 9 It is not shown in the figure. In addition, there is a main control display console on the bending machine body 1, which is used to adjust various parameters in the bending machine body 1. This main control display console can control the operation of the electric slide rail 26 and the electric slider 27.

[0039] like Figure 3 , Figure 4 , Figure 7 , Figure 8 and Fig. 9 As shown, a cooling assembly 3 is provided on the bending machine body 1, and the cooling assembly 3 is used in conjunction with the bending cutter head 14. The cooling assembly 3 includes a water tank 31 fixedly installed on the bending machine body 1, a piston cylinder 32 is fixedly installed on the bending machine body 1, and a piston disk 33 is provided for the internal sliding seal of the piston cylinder 32. A connecting rod 36 is fixedly installed on the top of the piston disk 33, and the connecting rod 36 is fixedly connected to the bending mechanism 11. A first delivery pipe 37 is fixedly inserted on the piston cylinder 32, and a second one-way valve 35 is fixedly installed in the first delivery pipe 37. A first one-way valve 34 is provided at the bottom of the piston cylinder 32, and the first one-way valve 34 is used in conjunction with the water tank 31. A water spray pipe 38 is fixedly installed at the end of the first delivery pipe 37, and a plurality of groups of nozzles 39 are provided on the water spray pipe 38, and the water spray pipe 38 can spray water on the bending part of the steel plate 13.

[0040] The first one-way valve 34 controls the water flow inside the water tank 31 to enter the piston cylinder 32, the second one-way valve 35 controls the water flow in the piston cylinder 32 to enter the first delivery pipe 37, the water delivery pump 43 can pump the water flow in the piston cylinder 32 into the second delivery pipe 41, and the flow meter 42 is electrically connected to the water delivery pump 43. The amount of water that can pass through the flow meter 42 and the amount of water contained in the water spray pipe 38 are equal to the amount of water in the piston cylinder 32.

[0041] When the worker steps on the button that controls the bending mechanism 11 to move the bending blade 14 downward, the bending mechanism 11 moves downward, and the connecting rod 36 moves downward, so that the connecting rod 36 pushes the piston disc 33 to move downward inside the piston cylinder 32, and then the water sucked into the piston cylinder 32 through the water tank 31 is discharged to the second one-way valve 35, enters the water spray pipe 38 through the second one-way valve 35, and is sprayed out from the nozzle 39 to the bent part of the steel plate 13. During the bending process, the steel plate 13 will generate heat due to the applied pressure. Spraying water through the nozzle 39 can help reduce the temperature of the bending area and avoid performance degradation of the material due to overheating. At the same time, when the steel plate 13 is bent, the humid environment helps to improve the plasticity of the steel plate 13, making it easier to deform during bending, thereby reducing the risk of material rupture.

[0042] When the bending mechanism 11 is reset and the bending head 14 moves upward, the bending mechanism 11 will move upward with the connecting rod 36, so that the piston disc 33 moves upward to suck the water in the water tank 31 into the piston cylinder 32 through the first one-way valve 34. According to the common sense of the piston needle tube, the piston disc 33 remains stationary. Since the pressure in the piston cylinder 32 is the same as the pressure in the first delivery pipe 37, the water in the piston cylinder 32 will not flow out through the first delivery pipe 37. The water in the piston cylinder 32 can only be pushed out by moving the piston disc 33 downward, thereby realizing the operation of absorbing and spraying water inside the water spray pipe 38. Water will only be sprayed out when the bending head 14 bends the steel plate 13 to ensure the quality of the steel plate 13 after bending, thereby avoiding the situation where the water spray pipe 38 keeps spraying water, resulting in waste of water resources.

[0043] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, an adjusting component 4 is provided on the piston cylinder 32, and the adjusting component 4 is used in conjunction with a water spray pipe 38. The adjusting component 4 includes a second delivery pipe 41 fixedly inserted on the piston cylinder 32, a water pump 43 is fixedly installed on the second delivery pipe 41, a flow meter 42 is fixedly installed on the second delivery pipe 41, the water pump 43 is used in conjunction with the flow meter 42, the water spray pipe 38 is a corrugated pipe, and the nozzle 39 is arranged at the trough of the water spray pipe 38, both ends of the water spray pipe 38 are respectively fixedly connected to the stopper 21, a connecting ring 44 is fixedly sleeved at the center of the water spray pipe 38, the first delivery pipe 37 passes through the connecting ring 44 and is connected with both ends of the water spray pipe 38, and the connecting ring 44 is fixedly connected to the outer surface of the bending machine body 1.

[0044] When steel plates 13 of different sizes are placed on the processing platform body 12, the electric guide rail works, and the electric slider 27 moves the ruler 21 and contacts the steel plate 13. In the process of the ruler 21 moving with the electric slider 27, the two rulers 21 approach each other and squeeze the two ends of the water spray pipe 38. At this time, the water spray pipe 38 will shrink and its internal space will also decrease. The shorter the length of the bending part of the steel plate 13, the smaller the water storage space inside the water spray pipe 38. Subsequently, when the bending cutter head 14 bends the steel plate 13, the bending mechanism 11 will move the piston plate 36 through the connecting rod 36. 3 moves downward in the piston cylinder 32, and then squeezes the water in the piston cylinder 32 to the first delivery pipe 37 and the second delivery pipe 41 at the same time. When the flow meter 42 calculates that the amount of water to be discharged from the second delivery pipe 41 is sufficient, the water delivery pump 43 is turned off, and the operation of the piston cylinder 32 injecting water into the second delivery pipe 41 is stopped. In this process, the water in the piston cylinder 32 can fill the entire interior of the water spraying pipe 38, and under the action of the piston disc 33, it is sprayed from the nozzle 39 to the bent part of the steel plate 13. The water spraying amount can be controlled according to the bending length of the bent steel plate 13, saving water resources;

[0045] It should be noted here that: at this time, the electric slider 27 will transmit the moving distance to the main control display console of the bending machine body 1, and then after calculation by the main control display console, on the premise that the inside of the water spray pipe 38 is full of water, the flow meter 42 is used to calculate the remaining water volume to be discharged, and the remaining water is discharged through the second delivery pipe 41 through the water pump 43.

[0046] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a groove for bending the steel plate 13 is provided on the processing platform body 12 , and the water spraying direction of the second conveying pipe 41 is toward the groove of the processing platform body 12 .

[0047] After the main control display station calculates and ensures that the inside of the water spray pipe 38 is full of water, the flow meter 42 calculates the remaining water volume that needs to be discharged, and the remaining water is discharged through the second delivery pipe 41 by the water pump 43. At this time, the water discharged by the piston cylinder 32 through the second delivery pipe 41 will be sprayed into the groove on the processing platform body 12 to wash away the impurities in the groove. At the same time, the back side of the steel plate 13 where it is bent is also sprayed with water to avoid the back side of the steel plate 13 where it is bent from breaking, thereby reducing the risk of material breakage and ensuring the quality of the steel plate 13 after bending.

[0048] like Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, a transmission member 5 is fixedly installed on the bending mechanism 11, and the transmission member 5 includes a gear rod 51 fixedly installed on the bending mechanism 11. A limit block 9 is fixedly installed on the outer surface of the bending machine body 1, and a limit rod 6 is rotatably installed on the limit block 9. One end of the limit rod 6 away from the limit block 9 is rotatably connected to the outer surface of the piston cylinder 32, and a gear 52 is fixedly sleeved on the outer surface of the limit rod 6, and the gear 52 is used in conjunction with the gear rod 51.

[0049] A slide groove 15 is provided on the outer surface of the bending machine body 1, and a slide rod 7 is slidably arranged in the slide groove 15. A tooth groove 71 is provided on the slide rod 7, and the tooth groove 71 is used in conjunction with the gear 52. A blanking component 8 is provided at the bottom of the slide rod 7, and the blanking component 8 can automatically push out the bent steel plate 13. The blanking component 8 includes a first bellows 81 fixedly installed at the bottom of the slide rod 7, a bent pipe 82 is fixedly inserted at the bottom of the first bellows 81, and a second bellows 83 is fixedly inserted at the bottom of the bent pipe 82. The bent pipe 82 is fixedly installed on the outer surface of the bending machine body 1, and the second bellows 83 is fixedly connected to the outer surface of the bending machine body 1. The outer end of the second bellows 83 is fixedly connected to the top column 84, and the first bellows 81 is connected to the bent pipe 82 and the second bellows 83.

[0050] When the bending cutter head 14 is moved downward by the bending mechanism 11 to bend the steel plate 13, the gear rod 51 is moved downward, and the gear rod 51 pushes the gear 52 to do the following. Figure 8 As shown in the figure, the gear 52 rotates counterclockwise, and because the gear 52 cooperates with the tooth groove 71 on the slide bar 7, the gear 52 will slide the slide bar 7 in the slide groove 15 upward, and the upward movement of the slide bar 7 will pull the first bellows 81 to extend, and the first bellows 81 will suck out the gas in the second bellows 83 through the bend 82, so that the second bellows 83 will shrink, avoiding being pressed by the bending cutter head 14 and causing the second bellows 83 to be damaged;

[0051] When the bending blade 14 is moved upward by the bending mechanism 11, the steel plate 13 has been bent by the bending blade 14, and the gear rod 51 moves upward, and the pole ear gear rod 51 pushes the gear 52 to do the following. Figure 8 The clockwise rotation as shown in the figure causes the slide bar 7 in the slide groove 15 to move downward. The downward movement of the slide bar 7 pushes the first bellows 81 downward and causes the first bellows 81 to contract. At this time, the gas in the first bellows 81 is pushed into the second bellows 83 through the bend 82. The second bellows 83 is filled with gas and extends, and the bent steel plate 13 is pushed down from the processing platform body 12 through the top column 84, thereby realizing the action of automatic unloading, which provides convenience for the staff.

[0052] Instructions for use: When using the bending machine body 1 to bend the steel plate 13, first, the staff holds the outer end of the steel plate 13 and places the steel plate 13 horizontally on the processing platform body 12. At this time, the electric slide rail 26 starts to bring the two electric sliders 27 closer to each other, so that the two blocking rulers 21 are closer to each other and clamp the steel plate 13. At this time, the steel plate 13 will be clamped by the two blocking rulers 21. The staff pushes the steel plate 13 to the inside of the two blocking rulers 21 until the steel plate 13 is completely in contact with the inside of the blocking ruler 21. At this time, the staff steps on the button for starting The button of the bending mechanism 11 causes the bending mechanism 11 to move downward with the bending tool head 14, and bends the steel plate 13 on the processing platform body 12, thereby realizing the bending action of the bending machine body 1 on the steel plate 13 on the processing platform body 12. An electric slide rail 26 and an electric slider 27 are added to the two stoppers 21, and the staff is no longer required to adjust the distance between the two stoppers 21 through the steel plate 13. Even if the staff makes an operating error and causes the bending tool head 14 to bend the steel plate 13, the bending tool head 14 will not press the staff's arm.

[0053] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
