Description

Technical Field

[0001] This utility model belongs to the field of secondary processing technology of profile steel, and specifically relates to a forming device for arc angle steel. Background Technology

[0002] Angle steel, as a finished steel profile, is normally a straight structure. However, many applications, such as curved steel trusses and ring beams, require secondary processing to bend the angle steel to the designed curvature. Currently, most commonly used bending and forming devices use combined pressure rollers for rolling. This method is mostly suitable for small-section angle steel. However, for angle steel with larger cross-sectional dimensions, due to its high rigidity, the bending force provided by the combined pressure rollers is difficult to meet the requirements. Therefore, hydraulic power is usually used for forming. Specifically, the angle steel is clamped between a fixed mold and a moving mold, and the mold is pushed by a hydraulic cylinder to press the angle steel to match the curvature of the fixed mold and the moving mold.

[0003] Because the curvature requirements for bending angle steel vary in actual processing, it is necessary to match fixed molds and moving molds with corresponding profiles according to each curvature requirement. This not only results in huge mold-making costs, but also requires changing fixed molds and moving molds according to curvature requirements, leading to high labor intensity and affecting work efficiency. Utility Model Content

[0004] This utility model provides a forming device for arc angle steel, which aims to reduce the mold-making cost and mold-changing labor intensity of the forming device for arc angle steel.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a circular arc angle steel forming device is provided, including a support platform, and a fixed mold group, a moving mold group, and a telescopic drive component connected to the support platform; the angle steel to be formed is placed between the fixed mold group and the moving mold group, and the telescopic drive component is used to drive the moving mold group to press the angle steel against the fixed mold group; the fixed mold group includes a mold base, an adjustment component, and an elastic template, the mold base is fixed to the support platform, the elastic template is connected to the side of the mold base facing the moving mold group and forms a fixed mold surface, and the adjustment component is connected to the mold base and independently applies a pushing force to different positions of the elastic template to adjust the curvature of the fixed mold surface.

[0006] In one possible implementation, the mold base has a horizontally penetrating groove on the side facing the moving module, and the elastic template has a connecting ear in the middle. The connecting ear extends into the groove and is connected to the middle groove wall of the groove through a rotating shaft. The adjustment assembly includes multiple sliding pushers, each of which is used to push the elastic template to different positions on both sides of the rotating shaft.

[0007] In some embodiments, a groove is provided in the groove corresponding to the position of each sliding pusher, and the groove extends along the movement direction of the moving module; the sliding pusher includes a threaded adjusting rod and a pressing head; the pressing head is slidably connected to the groove and abuts against the elastic template, the threaded adjusting rod passes through the mold base and is threadedly engaged with the mold base, and one end of the threaded adjusting rod passes through the groove and abuts against the pressing head.

[0008] For example, the mold base has clearance holes that communicate with the grooves on the top wall position directly above each groove; the sliding pusher also includes several adjusting shims, which are inserted between the pusher head and the bottom wall of the groove through the clearance holes.

[0009] For example, the end of the threaded adjusting rod away from the top pressure head extends out of the mold base and is equipped with an operating head. The top pressure head forms a top pressure arc surface on the side facing the moving mold, and the top pressure arc surface abuts against the elastic template.

[0010] In some embodiments, the moving module includes a slide block and a moving mold head detachably connected to the slide block; the slide block is slidably connected to the support platform and connected to the output end of the telescopic drive component; the end face of the moving mold head facing the fixed module forms a moving mold surface, and a pressure groove is provided on the bottom wall of the end of the moving mold head facing the fixed module; wherein, the moving mold surface and the fixed mold surface are used to cooperate to press the vertical surface of the angle steel, and the pressure groove is used to press the horizontal surface of the angle steel against the support platform.

[0011] In some embodiments, the pressing groove includes a first limiting surface and a second limiting surface; wherein, the first limiting surface is used to press the horizontal surface of the angle steel downward, and the second limiting surface is consistent with the target pressing arc of the angle steel and is used to press the edge of the horizontal surface of the angle steel along the movement direction of the moving die head.

[0012] For example, the moving mold head and the slide block have a first slot and a second slot with side openings on their adjacent edges, the openings of the first slot and the second slot are opposite to each other and form an insertion hole, and a pin is inserted into the insertion hole. The pin includes a first pin body and a second pin body. The first pin body is inserted into the first slot and the second pin body is inserted into the second slot.

[0013] For example, two guide grooves are arranged opposite each other on the support platform, and the two sides of the slide and the moving mold head are slidably connected to the two guide grooves respectively.

[0014] In some embodiments, a top seat is provided on the support platform, one end of the telescopic drive component is fixedly connected to the top seat, and the other end is connected to the moving module.

[0015] The beneficial effects of the arc angle steel forming device provided by this utility model are as follows: Compared with the prior art, the arc angle steel forming device of this utility model places the angle steel to be formed flat on the support platform and between the fixed mold group and the moving mold group. The angle steel can be pressed against the fixed mold surface by pushing the mold group with the telescopic drive component to obtain the arc consistent with the fixed mold surface. When it is necessary to adjust the forming arc of the angle steel, it is only necessary to adjust the fixed mold surface to the target arc by adjusting the component to change the pushing force on each position of the elastic template. Then, the corresponding moving mold group can be replaced. Thus, the same set of fixed mold groups can be used to meet different angle steel forming arc requirements, thereby reducing mold making costs, saving time for changing fixed mold groups, and reducing the labor intensity of mold changing.

In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0024] Please refer to the following: Figures 1 to 5 The present invention provides a method for forming arc-shaped angle steel. The arc-shaped angle steel forming device includes a support platform 10, and a fixed mold group 20, a moving mold group 30, and a telescopic drive member 40 connected to the support platform 10. An angle steel 50 to be formed is placed between the fixed mold group 20 and the moving mold group 30. The telescopic drive member 40 drives the moving mold group 30 to press the angle steel 50 against the fixed mold group 20. The fixed mold group 20 includes a mold base 21, an adjustment component, and an elastic template 23. The mold base 21 is fixed to the support platform 10. The elastic template 23 is connected to the side of the mold base 21 facing the moving mold group 30 and forms a fixed mold surface 231. The adjustment component is connected to the mold base 21 and independently applies a pushing force to different positions of the elastic template 23 to adjust the curvature of the fixed mold surface 231.

[0025] It should be noted that, considering that the angle steel 50 to be pressed is usually quite long, and for ease of operation, the support platform 10 in this embodiment can be set as a plane. The support platform 10 serves as the mounting base for the fixed module 20 and the moving module 30, and also provides horizontal support for the angle steel 50 to be pressed. Specifically, the angle steel 50 has two surfaces that form an angle. In order to improve the stability of the pressing process, the vertical surface 51 of the angle steel 50 is held between the moving module 30 and the fixed module 20 during the pressing process, while its horizontal surface 52 is attached to the support platform 10.

[0026] The arc angle steel forming device provided in this embodiment is mainly for secondary bending of angle steel 50 with large cross-sectional dimensions and high strength. Therefore, the telescopic drive component 40 is preferably made of hydraulic cylinder to ensure sufficient thrust output. Of course, this embodiment can also meet the bending and forming requirements of small cross-sectional angle steel 50, and is not limited here.

[0027] In this embodiment, the adjustment component can specifically be a push output end with several independent pushers at different positions of the elastic template 23. The elastic template 23 can specifically be a spring steel plate. By applying corresponding push forces to different positions of the spring steel plate, the spring steel plate is driven to bend to the target curvature. During the pressing process, the moving module 30 presses the vertical surface 51 of the angle steel 50 against the fixed model surface 231. In addition, it should be noted that from the perspective of the pressing process, the angle steel 50 can be preheated before pressing to eliminate toughness, so that the angle steel 50 after pressing and cooling can be consistent with the curvature of the fixed model surface 231.

[0028] Compared with the prior art, the arc angle steel forming device provided in this embodiment places the angle steel 50 to be formed flat on the support platform 10 and between the fixed mold group 20 and the moving mold group 30. The angle steel 50 is pressed against the fixed mold surface 231 by pushing the mold group 30 through the telescopic drive member 40 to obtain the arc consistent with the fixed mold surface 231. When it is necessary to adjust the forming arc of the angle steel 50, it is only necessary to adjust the pushing force on each position of the elastic template 23 by adjusting the component to adjust the fixed mold surface 231 to the target arc, and then replace the corresponding moving mold group 30. Thus, the same set of fixed mold groups 20 can meet the forming arc requirements of different angle steel 50, thereby reducing the mold making cost, saving the time of replacing the fixed mold group 20, and reducing the labor intensity of mold replacement.

[0029] In some embodiments, see Figure 3 and Figure 4 The mold base 21 has a horizontal through groove 211 on the side facing the moving module 30. The elastic template 23 has a connecting ear 232 in the middle. The connecting ear 232 extends into the groove 211 and is connected to the middle groove wall of the groove 211 through a rotating shaft 233. The adjustment assembly includes multiple sliding push parts 22. Each sliding push part 22 is used to push the elastic template 23 to different positions on both sides of the rotating shaft 233.

[0030] By adjusting the pushing amount of each sliding jacking component 22 on the elastic template 23, the elastic template 23 can be elastically deformed, thereby adjusting the fixed template surface 231 to the target curvature. The connecting ear 232 located in the middle of the elastic template 23 is connected to the groove 211 through the rotating shaft 233. The groove 211 can provide upper and lower limit constraints for the elastic template 23. At the same time, each sliding jacking component 22 can be symmetrically distributed on both sides of the rotating shaft 233, so that the elastic template 23 is subjected to balanced force and bending, which can improve the consistency between the fixed template surface 231 and the target curvature, thereby improving the bending and forming accuracy of the angle steel 50.

[0031] It should be noted that during the molding process, each sliding pusher 22 provides reverse support force to the elastic template 23. Therefore, the distribution spacing of the sliding pushers 22 should not be too large, and the distance between the positions of adjacent sliding pushers 22 acting on the elastic template 23 should not exceed 200mm.

[0032] For some possible implementations, please refer to [link / reference]. Figure 3 and Figure 4 Each sliding pusher 22 is provided in the groove 211 corresponding to the position of each sliding pusher 22. The sliding pusher 212 extends along the movement direction of the moving module 30. The sliding pusher 22 includes a threaded adjusting rod 221 and a pressing head 222. The pressing head 222 is slidably connected to the sliding groove 212 and abuts against the elastic template 23. The threaded adjusting rod 221 passes through the mold base 21 and is threadedly engaged with the mold base 21. One end of the threaded adjusting rod 221 passes through the sliding groove 212 and abuts against the pressing head 222.

[0033] By turning the threaded adjusting rod 221, it can be axially displaced relative to the mold base 21. Specifically, when the threaded adjusting rod 221 is turned in the forward direction, the threaded adjusting rod 221 can push the pressing head 222, which in turn pushes the elastic template 23, thereby increasing the bending arc of the elastic template 23. When the threaded adjusting rod 221 is turned in the reverse direction, the pressing head 222 slides in the opposite direction under the rebound force of the elastic template 23, thereby decreasing the bending arc of the elastic template 23. Each pressing head 222 is slidably connected in the corresponding slide groove 212, which can ensure the pushing stability of the pressing head 222 on the elastic template 23.

[0034] In some embodiments, such as Figure 4 As shown, the mold base 21 is provided with a clearance hole 213 communicating with the groove 211 on the top wall position directly above each slide groove 212; the sliding pusher 22 also includes several adjusting shims 223, which are inserted through the clearance hole 213 between the push head 222 and the bottom wall of the groove 211.

[0035] During the pressing process, the pressure force on the elastic template 23 is transmitted to the threaded adjusting rod 221 through the top pressure head 222, and then to the mold base 21 through the thread of the threaded adjusting rod 221. In order to avoid excessive stress and damage to the thread during the pressing process, an adjusting shim 223 can be inserted between the top pressure head 222 and the bottom wall of the groove 211. The force on the top pressure head 222 is directly transmitted to the mold base 21 through the adjusting shim 223, thereby avoiding stress on the thread, improving the overall load capacity of the fixed mold group 20, and thus improving the stability of the pressing operation.

[0036] It should be noted that you should refer to [link / reference]. Figure 4 The end of the threaded adjusting rod 221 away from the top pressing head 222 extends out of the mold base 21 and is provided with an operating head 2211. The top pressing head 222 forms a pressing arc surface 2221 on the side facing the moving mold 30, and the pressing arc surface 2221 abuts against the elastic template 23. The operating head 2211 can be a hexagonal structure suitable for matching a wrench, which facilitates the tightening operation. The pressing arc surface 2221 on the top pressing head 222, which abuts against the elastic template 23, facilitates the occurrence of dislocation between the elastic template 23 and the top pressing head 222 during the bending deformation process. This not only improves the smoothness of the curvature adjustment of the elastic template 23, but also helps the elastic template 23 to self-bend under the action of the top thrust, thereby improving the curvature adjustment accuracy of the fixed mold surface 231.

[0037] As one specific embodiment of the aforementioned moving module 30, please refer to Figures 2 to 4 The moving module 30 includes a slide 31 and a moving mold head 32 detachably connected to the slide 31; the slide 31 is slidably connected to the support platform 10 and connected to the output end of the telescopic drive member 40; the end face of the moving mold head 32 facing the fixed module 20 forms a moving mold surface 321, and the bottom wall of the end of the moving mold head 32 facing the fixed module 20 is provided with a pressing groove 322; wherein, the moving mold surface 321 and the fixed mold surface 231 are used to cooperate to press the vertical surface 51 of the angle steel 50, and the pressing groove 322 is used to press the horizontal surface 52 of the angle steel 50 against the support platform 10.

[0038] The moving die head 32 has a moving model surface 321 that matches the fixed model surface 231, thereby ensuring the forming accuracy of the angle steel 50. When it is necessary to adjust the forming curvature of the angle steel 50, the moving die head 32 can be removed from the slide 31 and replaced. Thus, a uniform slide 31 can be used, and the corresponding moving die head 32 can be made for different forming curvature requirements. Compared with replacing the entire moving die assembly 30, it can not only reduce the labor intensity of mold changing, but also save mold making costs.

[0039] Considering that the moving mold surface 321 mainly acts on the vertical surface 51 during the bending process of the angle steel 50, and the horizontal surface 52 of the angle steel 50 may wrinkle and deform as its vertical surface 51 bends, in this embodiment, the pressure groove 322 set on the bottom surface of the moving mold head 32 is used to press the horizontal surface 52 of the angle steel 50, thereby ensuring the flatness of the horizontal surface 52 of the angle steel 50 after the forming is completed; in addition, the pressure groove 322 can also improve the stability of the angle steel 50 and eliminate the risk of demolding during the forming process of the angle steel 50.

[0040] Specifically, in combination Figure 3 and Figure 5 Understanding the design, the pressure groove 322 includes a first limiting surface 3221 and a second limiting surface 3222. The first limiting surface 3221 is used to press downwards against the horizontal surface 52 of the angle steel 50, while the second limiting surface 3222 is aligned with the target forming arc of the angle steel 50 and is used to press against the edge of the horizontal surface 52 of the angle steel 50 along the movement direction of the moving die head 32. The function of the first limiting surface 3221 is to press against the horizontal surface 52 of the angle steel 50 to avoid the risk of demolding and ensure forming quality. The function of the second limiting surface 3222 is to provide a pushing force to the edge of the horizontal surface 52 of the angle steel 50 to ensure that the strongest angle portion of the angle steel 50 is fully stressed, thereby improving the bending forming quality of the angle steel 50.

[0041] As an optional connection structure between the moving mold head 32 and the slide 31, please refer to Figure 3 and Figure 5 The moving mold head 32 and the slide block 31 have side-opening first slots 311 and second slots 323 on their adjacent edges. The openings of the first slots 311 and the second slots 323 face each other and form an insertion hole. A pin 33 is inserted into the insertion hole. The pin 33 includes a first pin body 331 and a second pin body 332. The first pin body 331 is inserted into the first slot 311 and the second pin body 332 is inserted into the second slot 323.

[0042] Both the first slot 311 and the second slot 323 can have a narrowed opening structure with a slot size smaller than its internal size, such as a dovetail slot or a semi-circular slot with an arc greater than 180 degrees. This allows the first pin 331 to be inserted into the first slot 311 and the second pin 332 to be inserted into the second slot 323. The moving mold head 32 and the slide block 31 can then be connected as a whole by the pin 33. In this way, the moving mold head 32 can move away from the fixed mold group 20 along with the slide block 31 under the traction force of the telescopic drive 40, thereby realizing the demolding of the angle steel 50 and improving the convenience of the forming operation.

[0043] It should be understood that, in this embodiment, please refer to... Figure 1 and Figure 2The support platform 10 has two guide grooves 11 arranged opposite each other. The two sides of the slide block 31 and the moving mold head 32 are respectively slidably connected to the two guide grooves 11. Specifically, the guide grooves 11 can be inverted L-shaped structures welded and fixed to the support platform 10. The two opposite guide grooves 11 provide motion constraints for the slide block 31 and the moving mold head 32, thereby improving the stability of the movement of the moving mold head 32 under the drive of the slide block 31, and further improving the balance of the pushing force of the moving mold head 32 on the elastic template 23, which is beneficial to improving the forming quality of the angle steel 50.

[0044] Figure 2 The diagram shows an optional connection method for the telescopic drive component 40. A top seat 12 is provided on the support platform 10. One end of the telescopic drive component 40 is fixedly connected to the top seat 12, and the other end is connected to the moving module 30. Specifically, the top seat 12 can be welded and fixed to the support platform 10, aligned with the center of the moving module 30. The telescopic drive component 40 can be a hydraulic cylinder, with its cylinder barrel fixedly connected to the center of the top seat 12. The cylinder rod is connected to the moving module 30 (specifically, the slide 31) via fasteners. This allows the top seat 12 to provide a reaction force to the telescopic drive component 40, thereby improving the stability of the driving force output during the forming process of the angle steel 50.

[0045] Combination Figures 1 to 5 Understanding the working process of the arc angle steel forming device provided in this embodiment:

[0046] First, replace the moving die head 32 with the bending arc required for the angle steel 50 to be pressed. When replacing, pull out the pin 33. After the moving die head 32 separates from the slide block 31, it is removed from the guide groove 11. Then, slide the moving die head 32 with the required moving die surface 321 into the guide groove 11 and reinsert the pin 33 into the socket.

[0047] Then adjust the fixed model surface 231, and screw each threaded adjustment rod 221 in sequence. By pushing the elastic template 23 to different positions through each threaded adjustment rod 221, the elastic template 23 obtains the fixed model surface 231 with the required curvature. Then, insert the adjustment shim 223 into the side of the top pressure head 222 away from the moving module 30.

[0048] The angle steel 50 to be pressed (which may have undergone a preheating step) is placed horizontally on the support platform 10, between the fixed mold surface 231 and the moving mold surface 321. Then, the telescopic drive component 40 pushes the slide block 31, and the slide block 31 pushes the mold head 32 closer to the elastic template 23. During the pushing process, the groove 211 of the moving mold head 32 gradually presses against the horizontal surface 52 of the angle steel 50. The pushing continues until both sides of the vertical surface 51 of the angle steel 50 are completely in contact with the fixed mold surface 231 and the moving mold surface 321. After holding the pressure for a period of time, the telescopic drive component 40 drives the slide block 31 to move in the opposite direction, thereby causing the slide block 31 to drive the moving mold head 32 away from the elastic template 23 and thus demolding the angle steel 50.

[0049] It should be noted that for angle steel 50 with a large length, segmented forming can be carried out. That is, the forming process of the entire angle steel 50 can start from one end and form a segment at a time. The forming of adjacent segments should have a certain overlap until the other end of the angle steel 50 is reached after several consecutive forming processes. Of course, it is also possible to start from the middle of the angle steel 50 and form multiple segments towards both ends.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
