[0002] The stamping bending machine is a mechanical equipment used for metal sheet processing, which integrates the two functions of stamping and bending; it is widely used in automobile manufacturing, aerospace, home appliances, construction and other industries.

[0003] In the automobile production process, many automobile bracket parts are formed by stamping and bending metal plates. However, when the existing metal plates are bent, the material will rebound after the bending is completed due to the compressive strength of the metal plates, resulting in errors in the bending size. In addition, the existing bending machines are generally set in mechanical processing centers. The environment in the processing center is poor, and there are many metal debris and impurities. The metal debris and impurities are easily adhered to the bending mold, causing the metal plates to be scratched during extrusion, damaging the metal plates, affecting the bending quality, and reducing the production qualification rate. Furthermore, in order to adapt to the bending of some large metal plates, manufacturers usually purchase some bending machines with longer workbenches in machining centers. However, when bending metal plates of normal size, only a part of the bending mold in the workbench is performing the bending operation. At this time, metal debris and impurities are easily accumulated in the bending mold that is not performing the bending operation, which greatly increases the difficulty of subsequent cleaning.

[0025] The following is a detailed description of the process for improving the pass rate of extrusion bending of the metal plate 2: because the metal plate 2 has compressive strength, and the existing bending equipment does not have a good rebound compensation facility when extruding and bending the metal plate 2, and the metal plate 2 is usually placed manually, there is an error in the position of the metal plate 2. In summary, the metal plate 2 has dimensional errors after the extrusion and bending is completed, the precision is not up to standard, and the pass rate is low. Therefore, the following measures are proposed: First, the worker controls the first electric guide rail 101 through the control panel on the stamping and bending machine 1 to drive the two positioning plates 102 to move toward each other, so that a clamping area is formed between the two positioning plates 102; then the worker puts the metal plate 2 on the upper side of the two positioning plates 102, and then the worker controls the first electric guide rail 101 to drive the two positioning plates 102 to correct and position the metal plate 2, thereby avoiding When the metal plate 2 is manually placed, there will be errors that affect the subsequent bending accuracy; it should be noted here that the positioning plate 102 is detachably connected to the slider on the first electric guide rail 101, and the worker can install the matching positioning plate 102 according to the shape of the metal plate 2, so as to adapt to the correction clamping of different metal plates 2; after the metal plate 2 is corrected and positioned, the first electric guide rail 101 will control the two positioning plates 102 to move to the opposite sides, so that the distance between the two positioning plates 102 is greater than the width of the metal plate 2, so as to avoid the positioning plates 102 interfering with the normal operation of the upper mold 5 and affecting the subsequent bending of the metal plate 2, and then the stamping and bending machine 1 controls the upper mold 5 to move downward so that the upper mold 5 contacts the metal plate 2; and gradually press the metal plate 2 into the mold groove 3002 composed of the two lower molds 4; and in the process of the metal plate 2 entering the mold groove 3002, such as Figure 2 and Figure 3 As shown, in the initial state, the contact portion 4001 of the upper and lower molds 4 is in an upward tilted state. When viewed from right to left, the two lower molds 4 will rotate toward each other after being squeezed, and finally the two contact portions 4001 will contact each other, and then the metal plate 2 will be compacted by the lower mold 4, and the metal plate 2 will be squeezed and bent into shape by cooperating with the upper mold 5. After the extrusion is completed, the upper mold 5 is controlled to rise and reset to release the squeezing of the lower mold 4, and the lower mold 4 is rotated and reset, and the contact portion 4001 is tilted upward again, and while the contact portion 4001 is tilted upward, the metal plate 2 in the mold groove 3002 will be lifted upward to complete the demolding.

[0026] Furthermore, the existing bending machine is generally set in a mechanical processing center, the environment in the processing center is poor, there are many metal debris and impurities, and the metal debris and impurities are easily adhered to the bending mold, causing the metal plate 2 to be scratched during extrusion, damaging the metal plate 2, affecting the bending quality, and reducing the production qualification rate; therefore, Figure 2-Figure 5As shown: in the initial state, the contact portion 4001 of the upper and lower molds 4 is in an upwardly tilted state, and the mold groove 3002 and the collecting groove 10401 are in a connected state. At this time, the air pump on the stamping and bending machine 1 is started to blow air into the blowing pipe 107, and then the gas will be blown out from the first blowing port 10701, thereby blowing away the metal debris and impurities on the surface of the lower mold 4, and the first blowing port 10701 is tilted from the upper left to the lower right to blow the metal debris and impurities on the surface of the lower mold 4 into the collecting groove 10401 on the lower side of the mold groove 3002, and in this process, the air pump on the stamping and bending machine 1 is used to suck the suction pipe 105, thereby forming a circulating airflow in the mold groove 3002, and sucking away the metal debris and impurities in the mold groove 3002 and the collecting groove 10401, thereby improving the cleanliness of the mold and ensuring the production quality.

[0027] Furthermore, when the contact portion 4001 of the lower mold 4 is tilted upward, the pressure surface of the upper surface of the lower mold 4 is V-shaped. Metal debris and impurities are easily adhered to the angle of the upper surface of the lower mold 4, and are difficult to be blown into the connecting channel between the mold groove 3002 and the collecting groove 10401. Therefore, a guide groove 3003 is opened on the right side of the mold groove 3002. The gas blown out from the first blowing port 10701 will blow the dust and impurities at the angle of the upper surface of the lower mold 4 directly to the right into the guide groove 3003, and then enter the collecting groove 10401 through the through groove 10402. The guide groove 3003 is wide at the top and narrow at the bottom. When the airflow flows downward from the upper side of the guide groove 3003, the flow velocity will be greatly increased, thereby improving the suction effect.

[0028] Furthermore, when the metal plates 2 of different sizes are corrected and positioned by the two positioning plates 102, the positioning plate 102 will move on the sliding groove 3001, and then pull out the corresponding sealing curtain 103, and then seal the area of ​​the mold base 3 where the bending operation is not performed, to prevent metal debris and impurities in the machining center from entering the upper surface of the lower mold 4 where the bending operation is not performed, and continuously accumulating; and after the metal plate 2 is placed on the positioning plate 102, the upper side of the mold groove 3002 is in a closed state, so when the first blowing port 10701 blows out gas to blow away the metal debris and impurities on the upper surface of the lower mold 4, the mold groove 3002 is in a closed state, and at this time, the mold base 3 blows air on the left side and inhales air on the right side, which greatly increases the flow rate of the airflow from the mold groove 3002 into the collection groove 10401 and is finally sucked, thereby improving the airflow blowing effect on the metal debris and impurities on the upper surface of the lower mold 4, and improving the cleaning effect.

[0029] Furthermore, a branch pipe is provided in the air blowing pipe 107. After the upper mold 5 is pressed down to bend the metal plate 2, the second air blowing port 10702 will blow out cooling gas. At this time, the two contact parts 4001 are in contact with each other, and the mold groove 3002 and the collecting groove 10401 are in a separated state. At this time, the upper left part of the upper mold 5 is sealed by the sealing curtain 103, and the upper mold 5 will enter the mold groove 3002 after pressing the metal plate 2. Therefore, the cold air will flow directly from the left side of the mold groove 3002 to the middle part, and then directly contact the upper mold 5 and the lower mold 4, and then cool down the upper mold 5 and the lower mold 4, so as to avoid metal fatigue of the upper mold 5 and the lower mold 4 during the continuous stamping and bending process, and the strength reduction will affect the subsequent stamping and bending effect. At the same time, it is prevented that the upper mold 5 and the lower mold 4 are overheated and adhered to the metal plate 2, affecting the subsequent demolding.

[0030] On the basis of the above technical effects, the present invention also has the following advantages: An elastic membrane 106 is fixedly connected between each lower mold 4 and the mold base 3 to prevent metal debris and impurities from entering the rotating connection between the lower mold 4 and the mold base 3 when entering the collecting tank 10401 from the mold groove 3002, thereby affecting the subsequent use of the lower mold 4.

[0031] Embodiment 2: Based on embodiment 1, Figure 6-Figure 8 As shown, it also includes a fixed tube 11, a telescopic airbag 12 and a connecting tube 13; each positioning plate 102 is fixedly connected with a fixed tube 11; an air inlet pipe 1101 is arranged on the lower side of the fixed tube 11 located on the left side, and a pressure valve is arranged in the air inlet pipe 1101, and the air inlet pipe 1101 is connected with the mold groove 3002; a connecting tube 13 is connected between the two fixed tubes 11, and the connecting tube 13 is a telescopic tube; the opposite sides of the two positioning plates 102 are fixedly connected with telescopic airbags 12, and the telescopic airbags 12 are connected with the fixed tube 11; each telescopic airbag 12 is located at the upper front side of the mold base 3.

[0032] It also includes a cleaning tube 14; the cleaning tubes 14 are fixedly connected to the opposite sides of the two positioning plates 102; each cleaning tube 14 is connected to the corresponding telescopic airbag 12 through an air pipe, and a micro air pump is provided on the air pipe between the cleaning tube 14 and the telescopic airbag 12; the air outlet of each cleaning tube 14 faces the upper surface of the corresponding positioning plate 102.

[0033] The working principle of the above embodiment is as follows: The existing bending and stamping equipment has a wide range of uses. In order to improve the applicability of the equipment and ensure production efficiency, the equipment can also be used for the bending production of other plates. For thinner and larger metal plates 2 that need to be bent multiple times, when bending, since the front side of the bending part of the metal plate 2 is too long, the front side of the metal plate 2 is heavier after bending and will naturally bend downward, which can easily cause the metal plate 2 located at the corner of the positioning plate 102 and the mold groove 3002 to be deformed and damaged under the downward pressure of the upper mold 5, affecting the subsequent bending process. Therefore, when bending the thinner and larger metal plates 2, workers are required to hold the metal plates 2 for auxiliary operations, but the workers' auxiliary operations are more dangerous and prone to safety accidents. Therefore, when the upper mold 5 moves down to bend the metal plate 2 , the upper mold 5 contacts the metal plate 2, the metal plate 2 contacts the lower mold 4, and the contact parts 4001 of the two lower molds 4 fit together. At this time, a closed space is formed between the mold base 3, the lower mold 4, the upper mold 5 and the sealing curtain 103. The mold groove 3002 is divided into left and right parts by the upper mold 5. The gas blown out by the blowing pipe 107 on the left side of the mold groove 3002 cannot enter the collecting tank 10401. At this time, the air pressure on the left side of the mold groove 3002 continues to increase. When the air pressure is greater than the pressure valve in the air inlet pipe 1101, the air inlet pipe 1101 opens, and the gas on the left side of the mold groove 3002 enters the air inlet pipe 1101 and enters the two telescopic air bags 12 through the fixed pipe 11 and the connecting pipe 13, and then as shown in Figure 8 As shown, the two telescopic airbags 12 expand and extend upward, and contact the front side of the metal plate 2 after bending, and support the metal plate 2 to prevent the front side of the metal plate 2 from falling downward, causing the metal plate 2 to be deformed and damaged, affecting subsequent production and processing. When the upper mold 5 moves upward and resets, the contact parts 4001 of the two lower molds 4 are gradually separated, and the mold groove 3002 is connected with the collection groove 10401. At this time, the air flow on the left side of the mold groove 3002 will enter the collection groove 10401 and be extracted by the suction pipe 105. Therefore, the air pressure on the left side of the mold groove 3002 will continue to decrease, and the gas will no longer enter the air inlet pipe 1101, and then the cleaning pipe 1 is started. 4 and the telescopic airbag 12, draws the gas in the telescopic airbag 12 into the cleaning tube 14 and blows it out, thereby shrinking and resetting the telescopic airbag 12, and at the same time uses the blown gas to clean the upper surface of the positioning plate 102; then the worker can take out the bent metal plate 2, and then use the telescopic airbag 12 to support the front side of the thicker and thinner metal plates 2 instead of the worker; at the same time, the telescopic airbag 12 will expand and contract with the downward pressure and upward movement of the upper mold 5, so as to avoid the telescopic airbag 12 affecting the bending operation of the metal plate 2; it should be noted that during the working process, the blowing tube 107 is always in the blowing state, and the suction tube 105 is always in the suction state.

[0034] Embodiment 3: Based on embodiment 1, Fig. 9As shown, it also includes a second electric guide rail 201, an electric slide 202, an electric lifting plate 203 and a rear baffle 204; two second electric guide rails 201 are fixedly connected to the rear side of the stamping and bending machine 1; all the second electric guide rails 201 are slidably connected to the electric slide 202; the electric slide 202 is slidably connected to the electric lifting plate 203; the electric lifting plate 203 is connected to the rear baffle 204, and the height of the rear baffle 204 is consistent with the height of the metal plate 2 placed on the positioning plate 102.

[0035] The electric lifting plate 203 and the tailgate 204 are detachably connected.

[0036] The working principle of the above embodiment is as follows: When the metal plate 2 is corrected and positioned by the positioning plate 102, the worker can control the second electric guide rail 201, the electric slide 202 and the electric lifting plate 203 to accurately push the workpiece to the predetermined bending starting point with the rear baffle 204. When the worker puts the metal plate 2 on the upper side of the positioning plate 102, the worker can directly push the back side of the metal plate 2 to the rear baffle 204 to ensure that each bending operation starts from the same position, thereby ensuring the consistency and accuracy of the bending. At the same time, moving the rear baffle 204 can fix the workpiece to prevent it from moving during bending, reducing material Elastic rebound makes the final bending angle closer to the expected value, thereby improving the bending accuracy; and for workpieces that need to be bent multiple times or processed into complex shapes, the rear baffle 204 can be brought to different positions and stopped by the second electric guide rail 201, the electric slide 202 and the electric lifting plate 203 to achieve multi-stage bending positioning, ensuring that each stage of bending is accurate; and the electric lifting plate 203 and the rear baffle 204 are detachably connected, and workers can replace different rear baffles 204 according to different metal plates 2, thereby adapting to the stamping and bending of different metal plates 2.
