Description

TECHNICAL FIELD

[0001] The application relates to the technical field of angle steel bending, and particularly relates to a high-pressure iron tower angle steel inward bending die and a stamping device. BACKGROUND

[0002] The high-pressure iron tower angle steel is an important material for constructing a high-pressure transmission iron tower and has the characteristics of high strength, good ductility and weldability.

[0003] In actual use, the angle steel usually needs to be bent, and the angle steel bending is mainly operated through a cold bending method and a hot bending method. For the cold bending method, the angle steel is bent through mechanical force.

[0004] In the inward bending process of the high-pressure iron tower angle steel, the angle steel needs to be fixed through a clamp and then bent through a die. However, since the angle steel is arranged in an L shape, the existing clamp can only clamp and fix part of the side wall of the angle steel when the angle steel is fixed, so that the clamped area is small. When the angle steel is bent, the angle steel at the clamped position of the clamp generates a counteracting force in the opposite direction. Since the clamped area of the clamp is small, the supporting force provided by the clamp for the angle steel cannot completely offset the counteracting force. The counteracting force may cause the angle steel at the clamped position of the clamp to deform or have other problems, thereby affecting the bending quality and the structural integrity of the angle steel. SUMMARY

[0017] As a further scheme of the present application, the pushing assembly comprises a first guide sleeve which is slidingly installed on the first guide column, a first connecting plate is fixed to the first guide sleeve, a second air cylinder is fixed to the fixed plate and fixedly connected to the first connecting plate, and a first connecting rod is hingedly connected to the first clamping plate and hingedly connected to the first guide sleeve.

[0018] As a further scheme of the present application, the translation assembly comprises a lead screw which is rotationally installed on the machining table, a threaded sleeve is threadedly connected to the lead screw, a guide rod is fixed to the machining table, a sliding sleeve is slidingly installed on the guide rod, and a receiving plate is fixed to the sliding sleeve and fixedly connected to the threaded sleeve.

[0019] As a further scheme of the present application, the outer supporting mechanism comprises second guide columns which are fixed to the receiving plate and symmetrically arranged, second supporting plates are fixed to the ends of the second guide columns, second receiving rods are fixed to the second supporting plates, the second receiving rods are rotationally connected to the second clamping plates, and an adjusting assembly is arranged on the receiving plate and connected to the second guide columns.

[0020] As a further further scheme of the present application: the adjusting assembly comprises a second guide sleeve slidingly installed on the second guide column, a second connecting plate is fixedly connected to the second guide sleeve, a third cylinder is fixedly connected to the second connecting plate, and a second connecting rod is hingedly connected to the second clamping plate.

[0021] As a further further scheme of the present application: the driving assembly comprises a motor fixedly installed on the machining table, a transmission rod is rotatably installed on the machining table and connected to the output shaft of the motor, a small gear is fixed to the end of the transmission rod, a rotating rod is rotatably installed on the machining table and fixedly connected to the rotating plate, and a large gear fixed to the end of the rotating rod is engaged with the small gear.

[0023] Compared with the prior art, the present application has the following advantages: the present application can adjust the deflection angles of the first clamping plate and the second clamping plate respectively to comprehensively clamp the inner and outer sides of the angle steel, so as to prevent displacement of the angle steel during bending. Specifically, when the angle steel needs to be clamped, the outer clamping mechanism can be controlled to move by the translation assembly, so as to drive the second clamping plate to move towards the first clamping plate. When the angle steel is placed between the second clamping plate and the first clamping plate, the first clamping plate and the second clamping plate can be controlled to deflect by the inner clamping mechanism and the outer clamping mechanism respectively, so as to clamp the inner side of the angle steel by the first clamping plate and clamp the outer side of the angle steel by the second clamping plate. After clamping is completed, the bending assembly can be controlled to move by the rotating plate under the action of the driving assembly, so as to bend the angle steel by the supporting lower die and the arc upper die.

[0024] Since the reinforcing rib is located on the opposite side of the supporting lower die, the supporting force provided by the reinforcing rib to the connecting sleeve is opposite to the bending pushing force provided by the supporting lower die to the connecting sleeve, the bending pushing force provided by the supporting lower die is always changing around the connecting sleeve, and the rotating rod also drives the connecting sleeve to rotate, thereby driving the first rotating ring and the second rotating rod to move synchronously, so that the position of the reinforcing rib is constantly changed and always located on the opposite side of the supporting lower die, so as to ensure that the supporting force provided by the reinforcing rib is always opposite to the bending pushing force generated by the supporting lower die, thereby balancing the bending pushing force generated by the supporting lower die by constantly changing the supporting position of the reinforcing rib, and ensuring the stability and firmness of the arc upper die.

[0025] By adjusting the deflection angle of the first clamping plate and the second clamping plate, the first wedge and the second wedge are tightly fitted with the inner and outer sides of the angle steel, and the first wedge and the second wedge can provide support force to the first clamping plate and the second support plate when the first clamping plate and the second clamping plate are subjected to pulling force, which can increase the clamping area and the clamping strength of the angle steel, avoid displacement of the angle steel when the angle steel is bent, or deformation at the clamping position, thereby reducing the bending accuracy, and can also achieve the effect of clamping different specifications of angle steel.

[0040] Please refer to Figures 1-2 In the embodiments of the present application, the high-voltage iron tower angle steel inward bending die comprises a connecting sleeve 1 and a limiting hole 101 opened on the connecting sleeve 1.

[0041] An arc upper die 2 is rotatably installed on the connecting sleeve 1, a fixed column 3 is fixed at the bottom of the arc upper die 2, a rotating support assembly connected with the arc upper die 2 is arranged on the connecting sleeve 1, the rotating support assembly comprises a first rotating ring 4 and a second rotating ring 5 symmetrically arranged and fixedly installed on the connecting sleeve 1, the first rotating ring 4 is rotatably connected with the arc upper die 2, and a reinforcing rib 6 fixedly connected with the first rotating ring 4 and the second rotating ring 5 is fixed on the connecting sleeve 1.

[0042] Referring to Figures 3-11 , a stamping device, comprising:

[0043] a processing table 7, and a fixed plate 18 fixed on the processing table 7;

[0044] a driving assembly arranged on the processing table 7, a rotating plate 13 connected on the driving assembly, a bending assembly arranged on the rotating plate 13, and a supporting lower die 17 connected on the bending assembly, the driving assembly being capable of driving the supporting lower die 17 to move through the rotating plate 13 and the bending assembly;

[0045] an inner side supporting mechanism arranged on the fixed plate 18, the inner side supporting mechanism being connected with symmetrically arranged first clamping plates 22;

[0046] a translation assembly arranged on the processing table 7, an outer side supporting mechanism arranged on the translation assembly, symmetrically arranged second clamping plates 35 connected on the outer side supporting mechanism, and the translation assembly being capable of driving the second clamping plates 35 to move towards the direction of approaching or moving away from the first clamping plates 22 through the outer side supporting mechanism.

[0047] Specifically, a plurality of first wedge blocks 2201 and second wedge blocks 3501 are respectively fixed on the first clamping plate 22 and the second clamping plate 35, the connecting sleeve 1 is connected with the driving assembly, the fixed column 3 is fixed on the machining table 7, when it is needed to bend the angle steel, at the moment, the outer supporting mechanism can be driven to move by the translation assembly, so as to control the second clamping plate 35 to move towards the first clamping plate 22, when the angle steel is clamped between the first clamping plate 22 and the second clamping plate 35, under the action of the inner supporting mechanism, the deflection angle of the first clamping plate 22 is adjusted, so that the first clamping plate 22 fully abuts against the inclined surface on the inner side of the angle steel, at the same time, under the action of the outer supporting mechanism, the second clamping plate 35 is controlled to fully abut against the inclined surface on the outer side of the angle steel, so as to ensure that the angle steel does not shake when being bent, after the angle steel is fixed, the inner side of the angle steel will abut against the circular arc upper die 2, at the moment, the support lower die 17 is controlled to move towards the circular arc upper die 2 by the bending assembly, until the circular arc upper die 2 and the support lower die 17 abut against the angle steel, under the action of the driving assembly, the bending assembly is driven to move by the rotating plate 13, so as to inwardly bend the angle steel by the support lower die 17 and the circular arc upper die 2, by adjusting the deflection angle of the first clamping plate 22 and the second clamping plate 35, the first clamping plate 22 and the second clamping plate 35 can fully and closely abut against the inner and outer inclined surfaces of the angle steel, which significantly increases the clamping area of the angle steel, thereby improving the stability and reliability of clamping. At the same time, by virtue of the unique design of the first wedge blocks 2201 and the second wedge blocks 3501, the clamping strength of the angle steel can be further enhanced, and the angle steel can be firmly locked. When the angle steel is subjected to a bending force and further generates a pulling force on the first clamping plate 22 and the second clamping plate 35, due to the improvement of the clamping strength, the angle steel can always remain stable and will not displace, which effectively ensures that the bending angle and accuracy of the angle steel reach the best state.

[0048] Please refer to Figures 3-6 The driving assembly comprises a motor 8 fixedly installed on the machining table 7, a transmission rod 9 rotatably installed on the machining table 7 and connected with an output shaft of the motor 8, a small gear 10 fixedly installed at an end of the transmission rod 9, a rotating rod 11 rotatably installed on the machining table 7 and fixedly connected with the rotating plate 13, a large gear 12 fixedly installed at an end of the rotating rod 11 and engaged with the small gear 10, and the bending assembly comprises a guide rail 1301 fixedly installed on the rotating plate 13, a movable sleeve 14 slidably installed on the guide rail 1301, a movable plate 15 fixedly installed on the movable sleeve 14, a support lower die 17 fixedly connected with the movable plate 15, and a first air cylinder 16 fixedly connected with the movable plate 15 and installed on the rotating plate 13.

[0049] It should be noted that when assembling the bending mold, the connecting sleeve 1 and the rotating rod 11 can be mutually sleeved, and the end of the connecting sleeve 1 is provided with an embedding groove which is mutually clamped with the embedding block fixed on the rotating rod 11, so that the connecting sleeve 1 can rotate with the rotating rod 11, and at the same time, the fixed column 3 is fixed on the processing table 7 by bolts or other means, so that the position of the circular arc upper mold 2 is locked, at this time, the circular arc upper mold 2 and the supporting lower mold 17 are in the same horizontal plane, the circular arc upper mold 2 is adapted to the inner side of the angle steel to be processed, the supporting lower mold 17 is adapted to the outer side of the angle steel, and at this time, the reinforcing rib 6 is located on the side of the circular arc upper mold 2 away from the supporting lower mold 17;

[0050] Before the angle steel is started to be bent, under the action of the first cylinder 16, the movable plate 15 is located at the end of the stroke away from the circular arc upper mold 2, so that the distance between the supporting lower mold 17 and the circular arc upper mold 2 is maximum, when the angle steel needs to be bent, the angle steel can be fixed by the first clamping plate 22 and the second clamping plate 35, the inner side of the angle steel will be attached to the circular arc upper mold 2, at this time, the first cylinder 16 works and pushes the movable plate 15 to move, thereby driving the movable sleeve 14 to slide along the length direction of the guide rail 1301, the movable plate 15 also drives the supporting lower mold 17 to move, until the inclined surface of the supporting lower mold 17 is attached to the outer side of the angle steel;

[0051] Subsequently, the motor 8 works and drives the pinion 10 to rotate through the transmission rod 9, since the pinion 10 and the gear 12 are engaged, the gear 12 is synchronously and reversely rotated, thereby driving the rotating rod 11 to rotate, the rotating rod 11 will drive the movable sleeve 14 to move through the rotating plate 13, so as to drive the supporting lower mold 17 to move through the movable plate 15, under the action of the supporting lower mold 17, the bending force around the circular arc track of the circular arc upper mold 2 is provided to the angle steel, so as to bend the angle steel, at the same time, since the reinforcing rib 6 is located on the opposite side of the supporting lower mold 17, the supporting force provided by the reinforcing rib 6 to the connecting sleeve 1 is opposite to the bending pushing force provided by the supporting lower mold 17 to the connecting sleeve 1. At the same time, the bending pushing force generated by the supporting lower mold 17 changes around the connecting sleeve 1, and the rotating rod 11 drives the connecting sleeve 1 to rotate, thereby driving the first rotating ring 4 and the second rotating ring 5 to synchronously move, so that the position of the reinforcing rib 6 continuously changes and is always opposite to the supporting lower mold 17. Such design ensures that the supporting force provided by the reinforcing rib 6 is always opposite to the bending pushing force generated by the supporting lower mold 17, by continuously changing the supporting position of the reinforcing rib 6, the bending pushing force generated by the supporting lower mold 17 is effectively balanced, thereby ensuring the stability and firmness of the circular arc upper mold 2 in the whole bending process, avoiding the problems of mold damage or bending precision reduction caused by uneven stress.

[0052] Preferably, when the rotating rod 11 is rotated to the desired bending angle, the supporting lower die 17 can be controlled to reset. Because there is a certain elastic stress inside the angle steel after bending, it may cause the angle steel to rebound. Therefore, the rotating rod 11 can be controlled to rotate again, and the angle steel is bent again by the supporting lower die 17 until the generated elastic stress is eliminated, ensuring that the bending quality of the angle steel reaches the best state, effectively avoiding the bending angle deviation caused by rebound, and meeting the strict requirements of high-voltage iron tower angle steel on bending quality.

[0053] When the angle steel is bent, a large bending force is required. By driving the large gear 12 to rotate through the pinion gear 10, the power output by the motor 8 can be torque amplified, which not only meets the requirement of bending force, but also effectively reduces the load of the motor 8, ensures the safe operation of the motor 8, and avoids damage due to overload. At the same time, this transmission mode can also accurately control the output rate, so as to realize accurate control of the bending angle of the angle steel.

[0054] Please refer to Figure 3 、 Figure 4 、 Figures 7-9 , the inner side supporting mechanism includes first guide columns 19 fixed on the fixed plate 18 and arranged symmetrically, the first guide columns 19 are fixed with first support plates 20 at the end, the first support plates 20 are fixed with first receiving rods 21, the first receiving rods 21 are rotationally connected with the first clamping plates 22, the fixed plate 18 is provided with a pushing assembly connected with the first guide columns 19, wherein the pushing assembly includes a first guide sleeve 23 slidingly installed on the first guide column 19, the first guide sleeve 23 is fixed with a first connecting plate 25, the fixed plate 18 is fixed with a second air cylinder 26 fixedly connected with the first connecting plate 25, and the first guide sleeve 23 is hinged with a first connecting rod 24 hinged with the first clamping plate 22.

[0055] In detail, before the angle steel is clamped, under the action of the second air cylinder 26, the first connecting plate 25 is located at the end of the stroke towards the fixed plate 18, the spacing between the first guide sleeve 23 and the first support plate 20 is maximum, under the action of the first connecting rod 24, the included angle between the two first clamping plates 22 is minimum, and the included angle between the two first clamping plates 22 and the first support plate 20 is equal, and the side surfaces of the two first clamping plates 22 away from each other are fixed with a plurality of first wedge blocks 2201 distributed equidistantly;

[0056] When the angle steel needs to be clamped, the inner side inclined surface of the angle steel is inclined towards the direction of the first clamping plate 22, and under the action of the translation assembly, the second clamping plate 35 is controlled to move towards the direction of the first clamping plate 22 by the outer clamping mechanism, until the angle steel is placed between the first clamping plate 22 and the second clamping plate 35. Since the included angle of the two first clamping plates 22 is smaller than the included angle of the angle steel, under the action of the second cylinder 26, the first connecting plate 25 is pushed to move, so that the first guide sleeve 23 moves along the length direction of the first guide column 19 and moves towards the direction of the first support plate 20. The first guide sleeve 23 also drives the first connecting rod 24 to move, so that the two first clamping plates 22 rotate around the first receiving rod 21, and the rotation angles are equal and the rotation directions are opposite. The included angle between the two first clamping plates 22 and the inner side surface of the angle steel gradually decreases, until the first clamping plate 22 controls the first wedge block 2201 to complete the fitting with the inner side surface of the angle steel. At this time, the second cylinder 26 stops working.

[0057] Preferably, when performing the inward bending operation of the high-voltage iron tower angle steel, after the clamp clamps the angle steel, the mold applies a bending force to the angle steel to cause the bending deformation. At this time, the angle steel will be subjected to a bending force directed in the bending direction, while the clamp will be subjected to a pulling force and a reaction force at the clamping position. Since the deflection angle of the first clamping plate 22 is adjustable, when the included angle of the inner side of the angle steel changes, the deflection angle of the first clamping plate 22 can be adjusted to achieve adaptive control, so that the first wedge block 2201 tightly fits the inner side of the angle steel. When the first clamping plate 22 is subjected to a pulling force, the first wedge block 2201 can provide support force for it. This design not only increases the area and strength of the clamping of the angle steel, effectively avoids the displacement of the angle steel during bending or the deformation at the clamping position, thereby preventing the problem of reducing the bending precision; but also can clamp angle steels of different specifications, greatly expanding the application scope of the present application and meeting the needs of high-voltage iron tower angle steel bending processing in different scenarios.

[0058] Please refer to Figure 3 , Figure 4 , Figure 7 , Figure 10 , Figure 11The translation assembly comprises a screw rod 27 rotatably installed on the machining table 7, a threaded sleeve 28 threadedly connected to the screw rod 27, a guide rod 30 fixed on the machining table 7, a sliding sleeve 31 slidably installed on the guide rod 30, a receiving plate 29 fixed on the sliding sleeve 31 and fixedly connected with the threaded sleeve 28, the outer support mechanism comprises second guide columns 32 fixed on the receiving plate 29 and symmetrically arranged, second support plates 33 fixed at the ends of the second guide columns 32, second receiving rods 34 fixed on the second support plates 33, and second clamping plates 35 rotatably connected with the second receiving rods 34, and the receiving plate 29 is provided with an adjusting assembly connected with the second guide columns 32, wherein the adjusting assembly comprises a second guide sleeve 36 slidably installed on the second guide columns 32, a second connecting plate 37 fixed on the second guide sleeve 36, a third cylinder 39 fixedly connected with the second connecting plate 37 on the receiving plate 29, and a second connecting rod 38 hinged to the second clamping plate 35 on the second guide sleeve 36.

[0059] Further, the two second clamping plates 35 are fixed on the sides away from each other with a plurality of second wedge blocks 3501 equally distributed, when clamping the angle steel, since the required clamping thickness of the angle steel may be different, the clamping angle of the angle steel may also be different, it is necessary to adjust the distance between the second clamping plate 35 and the first clamping plate 22, and the angle between the two second clamping plates 35, in the initial state, under the action of the screw rod 27, the threaded sleeve 28 is located at the end of the stroke away from the first clamping plate 22, so that the distance between the second clamping plate 35 and the first clamping plate 22 is maximum, under the action of the third cylinder 39, the second connecting plate 37 and the second guide sleeve 36 are located at the end of the stroke away from the second support plate 33, so as to control the angle between the two second clamping plates 35 to be maximum by the second connecting rod 38, and the angle between the second support plate 33 is the same;

[0060] When it is necessary to clamp the angle steel, at this time, the screw rod 27 rotates and drives the threaded sleeve 28 to move, thereby driving the receiving plate 29 to move, which will control the sliding sleeve 31 to move along the length direction of the guide rod 30. Since the guide rod 30 and the sliding sleeve 31 have a guiding effect, it can be ensured that the threaded sleeve 28 moves along the length direction of the screw rod 27 and does not rotate with the screw rod 27. The receiving plate 29 also drives the second guide column 32 to move to control the second clamping plate 35 to move towards the first clamping plate 22. When the angle steel is fixed between the first clamping plate 22 and the second clamping plate 35, the screw rod 27 stops rotating. At this time, the third cylinder 39 can drive the second connecting plate 37 to move, thereby driving the second guide sleeve 36 to move along the length direction of the second guide column 32 to control the two second clamping plates 35 to rotate around the second receiving rod 34 in opposite directions with the same rotation angle. When the second wedge blocks 3501 on the two second clamping plates 35 fully contact the outer side of the angle steel, the third cylinder 39 stops moving. At this time, the angle steel is completely clamped.

[0061] Preferably, by respectively adjusting the deflection angles of the first clamping plate 22 and the second clamping plate 35, the inside and outside of the angle steel can be fully clamped. This design not only increases the clamping area of the angle steel, but also makes the angle steel be stably clamped in all directions. Furthermore, the first wedge block 2201 and the second wedge block 3501 further enhance the clamping strength of the angle steel. During the bending process of the angle steel, this full and high-strength clamping method can effectively prevent the angle steel from displacement or shaking, thereby ensuring the accuracy and stability of the bending operation and improving the quality and efficiency of the angle steel bending.
