Description

Technical Field

[0001] The present invention relates to the technical field of box-type substation box body forming, and specifically provides a bending device for preparing box-type substations. Background Art

[0002] A box-type substation is a complete set of power equipment that integrates transformers, high and low voltage switch cabinets, capacitor banks, relay protection devices, measuring instruments, control equipment, etc. into one or more boxes. It has the characteristics of compact structure, small floor area, convenient installation, and simple maintenance. It is widely used in urban power grid transformation, industrial parks, residential areas, commercial centers and other occasions. The metal shell box body is one of the core components of the box-type substation. The metal shell box body is usually made of sheet metal through shearing, stamping, bending, welding, surface treatment and assembly processing. Among them, bending is the most important step in the shape forming process of the metal shell box body.

[0003] Currently, when performing a 90-degree bending process on the box body, by placing the sheet between the supporting base and the bending pressing head, and then when the bending pressing head moves downward to press the sheet for bending, the two sides of the bending part of the sheet are directly flipped. However, when the sheet is bent and flipped, it is easy to rebound under the action of its own gravity and its own characteristics due to the lack of supporting force at the lower ends of its two sides, thus reducing the quality of the box body bending forming. Secondly, in order to prevent one side of the bending part of the sheet from being larger in size, and to prevent the sheet from deforming under its own gravity when the sheet is bent and flipped, when the sheet is turned over to the horizontal state after bending, a large impact force will be generated between the sheet and the supporting platform. It is necessary to manually support the sheet continuously, but in this way, the convenience of the sheet bending forming process is reduced. Summary of the Invention

[0004] In view of the above problems, the embodiments of the present application provide a bending device for preparing box-type substations to solve the technical problems in the related art.

[0005] To achieve the above object, the embodiments of the present application provide the following technical solutions: A bending device for preparing box-type substations includes a support table and a driving accommodation box installed on its top through a bracket. A supporting platform is installed on the top of the support table. A supporting base with a V-shaped top is jointly installed on the supporting platform and the upper top of the support table. The V-shaped angle at the top of the supporting base is 90 degrees. A double-support auxiliary shaping mechanism is jointly installed on the supporting platform and the supporting base. The lower end of the driving accommodation box is installed with a connecting frame through a vertically sliding fixed clamp. The lower end of the connecting frame is installed with a bending pressing head. The bending pressing head cooperates with the supporting base to bend the sheet into 90 degrees. An existing lifting driving source for driving the fixed clamp to drive the connecting frame and the bending pressing head to move downward to bend the sheet is arranged in the driving accommodation box.

[0006] The double-support auxiliary shaping mechanism includes a supporting panel and a support bar. The dimension of the supporting panel in the width direction is greater than that of the support bar in the width direction. The supporting panel and the support bar are respectively hinged to both sides of the supporting base arranged along its width direction. The supporting panel is located on the side of the supporting base away from the bracket. The supporting panel is used to support the plate. The lower ends of the supporting panel and the support bar are connected by a synchronous flipping connection group installed on the supporting platform. An auxiliary shaping pressing frame is sleeved outside the connecting frame. The auxiliary shaping pressing frame is connected to the connecting frame through a connecting bar. Positioning components that are inserted and matched with the supporting base are installed at both lower ends of the auxiliary shaping pressing frame arranged along its length direction.

[0007] In a possible implementation manner, two gaskets are installed on the top of the supporting platform, and both gaskets are located on the side of the supporting base away from the bracket.

[0008] When the bending pressing head moves downward to bend the plate, the auxiliary shaping pressing frame drives the synchronous flipping connection group through the positioning components to drive the supporting panel and the support bar to flip and assist in supporting the plate.

[0009] Supplementary panels are installed on the end faces of the supporting panel and the support bar away from the supporting platform. When the supporting panel and the support bar are in a horizontal state, the top of the supplementary panel is flush with the top of the supporting base. An auxiliary lifting group for assisting in pulling the supporting panel to flip is jointly installed on the auxiliary shaping pressing frame and the bracket.

[0010] In a possible implementation manner, a limiting strip that can be adjusted in position along the width direction of the supplementary panel is installed on the supplementary panel of the support bar. The limiting strip is used to limit the plate pushed in horizontally.

[0011] In a possible implementation manner, the synchronous flipping connection group includes a Y-shaped groove opened on the supporting platform and located below the supporting base. Two sliding grooves arranged along the width direction of the supporting base are also opened on the top of the supporting platform. The two sliding grooves are respectively communicated with the two tops of the Y-shaped groove. A sliding plate is horizontally slidably connected in the sliding groove. Swing rods arranged along the length direction of the sliding plate are respectively hinged between the two sliding plates and the corresponding supporting panel and support bar. A lifting plate that slides up and down is connected to the vertical section of the Y-shaped groove. A push rod arranged along the length direction of the lifting plate is hinged between the lifting plate and the sliding plate. The push rods connected to the supporting panel and the support bar as a whole are arranged in an inverted V shape. A plurality of uniformly arranged return springs are installed between the lifting plate and the top of the Y-shaped groove.

[0012] In a possible implementation manner, the auxiliary shaping pressing frame is composed of two inclined pressing plates, fixing pieces installed on the opposite surfaces of the two inclined pressing plates and connected to the connecting bar, and a connecting plate installed on the side of the connecting bar away from the connecting frame. The connecting frame is located between the two inclined pressing plates, and the lower inclined surface of the inclined pressing plate and the inclined surface corresponding to the bending pressing head are on the same plane. The inclined pressing plate is used to assist in supplementing the pressing surface of the bending pressing head on the plate.

[0013] In a possible implementation manner, the lower end of the connecting bar is in a conical structure.

[0014] In a possible implementation manner, rib plates are installed between the connecting frame and the two inclined pressing plates.

[0015] In a possible implementation manner, the auxiliary lifting group includes two ropes symmetrically arranged along the length direction of the supporting and supporting panel between the supporting and supporting panel and the bracket. Two pulleys one are rotatably connected to the bracket through supports and are symmetrically arranged along the length direction of the bracket. Two pulleys two are rotatably connected to the tops of the two connecting plates through fixed seats. The ropes bypass the pulleys one and the pulleys two, and limit pieces are installed on both the support and the fixed seat. The limit pieces are used to limit the ropes wound around the pulleys one and the pulleys two.

[0016] In a possible implementation manner, the positioning component includes a positioning insertion rod installed at the bottom of the connecting plate. The positioning insertion rod slides up and down through the supporting base, and a pressing and matching component for driving the lifting plate to move downward in cooperation is installed between the lower end of the positioning insertion rod and the lifting plate.

[0017] In a possible implementation manner, the pressing and matching component is a supplementary cylinder installed at the lower end of the lifting plate and arranged along the length direction of the lifting plate. The supplementary cylinders correspond to the insertion rods one by one, and through grooves communicating with the supplementary cylinders are opened on the lifting plate.

[0018] One or more of the above technical solutions in the embodiments of the present invention have at least one of the following beneficial effects:

[0019] 1. When bending the plate in the present invention, through the cooperation of the supporting and supporting panel, the supporting bar, and the synchronous flipping connection group, the supporting and supporting panel and the supporting bar are flipped synchronously as the side of the plate is bent and flipped, so as to always support the plate, and there is no need to manually support the plate for bending processing, which improves the convenience of the plate bending and forming processing. Moreover, the cooperation of the supporting and supporting panel, the supporting bar, and the auxiliary shaping pressing frame can also assist in pressing and shaping the plate during bending, improving the quality of the plate bending, and further improving the quality of the formed box body.

[0020] 2. When the auxiliary shaping pressing frame in the present invention moves downward and drives the synchronous flipping connection group to drive the supporting panel and the supporting strip to flip, it also drives the auxiliary lifting group to assist in driving the supporting panel to flip, avoiding the problem of inconvenient flipping due to the large volume of the supporting panel, thereby improving the quality of the sheet metal bending forming. At the same time, it also realizes the integrated driving operation of the synchronous flipping connection group and the auxiliary lifting group.

[0021] 3. The connecting frame in the present invention drives the auxiliary shaping pressing frame to move downward, and the positioning component cooperates with the supporting base to guide the up and down movement of the auxiliary shaping pressing frame and the bending pressing head, thereby improving the accuracy of the alignment between the bending pressing head and the supporting base, and further improving the quality of the sheet metal bending forming.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0032] In order to enable those in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments

[0033] Refer to Figure 1 , a bending device for the preparation of a box-type substation, including a support platform 1 and a driving accommodation box 3 installed on its top through a bracket 2. A supporting platform 4 is installed on the top of the support platform 1. A supporting base 5 with a V-shaped top is jointly installed on the top of the supporting platform 4 and the support platform 1. The V-shaped angle at the top of the supporting base 5 is 90 degrees. A double-support auxiliary shaping mechanism 6 is jointly installed on the supporting platform 4 and the supporting base 5

[0034] Refer to Figure 1 And Figure 5 , the lower end of the driving accommodation box 3 is installed with a connecting frame 7 through an up-and-down sliding fixed clamp. The lower end of the connecting frame 7 is installed with a bending pressing head 8. The bending pressing head 8 cooperates with the supporting base 5 to bend the plate 9 into 90 degrees. An existing lifting driving source for driving the fixed clamp to drive the connecting frame 7 and the bending pressing head 8 to move downward to bend the plate 9 is arranged in the driving accommodation box 3

[0035] Refer to Figure 1 , Figure 2 , Figure 3 And Figure 5, the double-support auxiliary shaping mechanism 6 includes a supporting panel 60 and support bars 61. The dimension of the supporting panel 60 in the width direction is greater than that of the support bars 61 in the width direction. The supporting panel 60 and the support bars 61 are respectively hinged to both sides of the supporting base 5 arranged along its width direction. The supporting panel 60 is located on the side of the supporting base 5 away from the bracket 2. The supporting panel 60 is used to support the plate 9. The lower end faces of the supporting panel 60 and the support bars 61 are connected by a synchronous flipping connection group 62 installed on the supporting platform 4. An auxiliary shaping pressing frame 63 is sleeved outside the connecting frame 7. The auxiliary shaping pressing frame 63 is connected to the connecting frame 7 through a connecting bar 65. Positioning components 64 that are inserted and matched with the supporting base 5 are installed at both lower ends of the auxiliary shaping pressing frame 63 arranged along its length direction.

[0036] Refer to Figure 1 and Figure 3 , two gaskets 40 are installed on the top of the supporting platform 4. Both of the two gaskets 40 are located on the side of the supporting base 5 away from the bracket 2. When the supporting panel 60 is in a horizontal state, both of the two gaskets 40 are located below the supporting panel 60. The two gaskets 40 are used to support the supporting panel 60 in the horizontal state, so as to improve the stability of the supporting panel 60 in the horizontal state.

[0037] Refer to Figure 1 , Figure 3 and Figure 5 , when the bending pressing head 8 moves downward to bend the plate 9, the auxiliary shaping pressing frame 63 drives the synchronous flipping connection group 62 through the positioning components 64 to drive the supporting panel 60 and the support bars 61 to flip and assist in supporting the plate 9.

[0038] Refer to Figure 1 , Figure 3 and Figure 5 , supplementary panels 66 are installed on the end faces of the supporting panel 60 and the support bars 61 away from the supporting platform 4. When the supporting panel 60 and the support bars 61 are in a horizontal state, the top of the supplementary panel 66 is flush with the top of the supporting base 5. An auxiliary lifting group 67 for assisting in pulling the supporting panel 60 to flip is jointly installed on the auxiliary shaping pressing frame 63 and the bracket 2.

[0039] In the initial state, the supporting panel 60 and the support bars 61 are both in a horizontal state, and the top of the supplementary panel 66 is flush with the top of the supporting base 5, so as to facilitate supporting both sides of the bending part of the plate 9 after the plate 9 is placed. Then, the plate 9 is horizontally placed on the supporting panel 60, and the plate 9 is horizontally pushed so that the bending part of the plate 9 enters between the bending pressing head 8 and the supporting base 5.

[0040] After that, the lifting drive source drives the connecting frame 7 to drive the bending pressing head 8 to move downward to bend the sheet 9. The connecting frame 7 drives the auxiliary shaping pressing frame 63 to move downward. The positioning assembly 64 cooperates with the supporting base 5 to guide the up and down movement of the auxiliary shaping pressing frame 63. When the bending pressing head 8 contacts the sheet 9, the positioning assembly 64 cooperates with the synchronous flipping connection group 62. When the bending pressing head 8 presses the sheet 9 to bend and enters the V-shaped surface of the supporting base 5, the synchronous flipping connection group 62 drives the supporting panel 60 and the supporting strip 61 to rotate along their respective hinge points until the supplementary panel 66 on the supporting panel 60 and the supporting strip 61 aligns with the corresponding inclined plane in the V-shaped surface of the supporting base 5. The supplementary panel 66 assists in supporting the two end faces of the sheet 9 bent at 90 degrees. During the downward movement of the auxiliary shaping pressing frame 63, it also drives the supporting panel 60 to flip through the auxiliary lifting group 67, avoiding the problem of inconvenient flipping due to the large volume of the supporting panel 60.

[0041] The flipping of the supporting panel 60 and the supporting strip 61 can not only support the sheet 9 during bending and flipping, eliminating the need for manual support of the bent sheet 9, improving the convenience of bending and forming the sheet 9, but also cooperate with the auxiliary shaping pressing frame 63 to press and shape the two ends of the sheet 9 bent at 90 degrees, thus improving the quality of bending and forming the sheet 9.

[0042] Refer to Figure 5 , a limiting strip 610 that can be adjusted in position along the width direction of the supplementary panel 66 is installed on the supplementary panel 66 of the supporting strip 61, and the limiting strip 610 is used to limit the horizontally pushed sheet 9.

[0043] Refer to Figure 3 , Figure 4 and Figure 5 , the synchronous flipping connection group 62 includes a Y-shaped groove 620 opened on the supporting platform 4 below the supporting base 5. Two sliding grooves 621 arranged along the width direction of the supporting base 5 are also opened at the top of the supporting platform 4. The two sliding grooves 621 are respectively communicated with the two tops of the Y-shaped groove 620. A sliding plate 622 is horizontally slidably connected in the sliding groove 621. Swing rods 623 arranged along the length direction of the sliding plate 622 are respectively hinged between the two sliding plates 622 and the corresponding supporting panel 60 and supporting strip 61. A lifting plate 624 that slides up and down is connected to the vertical section of the Y-shaped groove 620. A push-pull rod 625 arranged along the length direction of the lifting plate 624 is hinged between the lifting plate 624 and the sliding plate 622. The push-pull rods 625 connected to the supporting panel 60 and the supporting strip 61 are arranged in an overall inverted V shape. A plurality of uniformly arranged return springs 626 are installed between the lifting plate 624 and the top of the Y-shaped groove 620.

[0044] The auxiliary shaping pressing frame 63 drives the positioning component 64 to move downward. When the bending pressing head 8 contacts the sheet 9 and continues to move downward, the positioning component 64 pushes the lifting plate 624 to move downward. When the lifting plate 624 moves downward, it drives two sliding plates 622 to move towards the supporting base 5 through the push-pull rod 625. During the movement of the sliding plate 622, it pushes the corresponding supporting panel 60 and the supporting strip 61 to rotate along their respective hinge points through the swing rod 623, so as to realize that the supporting panel 60 and the supporting strip 61 rotate along with the bending of the sheet 9 while always supporting the sheet 9.

[0045] Refer to Figure 1 、 Figure 2 And Figure 5 As shown in FIGS.

[0046] Refer to Figure 2 The lower end of the connecting strip 65 is in a conical structure to prevent the bent side of the sheet 9 from colliding with the connecting strip 65.

[0047] Refer to Figure 5 As shown in FIGS.

[0048] Refer to Figure 1 、 Figure 2 And Figure 4 The auxiliary lifting group 67 includes two ropes 670 symmetrically arranged along the length direction of the supporting panel 60 and installed between the supporting panel 60 and the bracket 2. Two pulleys 671 are rotatably connected to the bracket 2 through supports and symmetrically arranged along the length direction of the bracket 2. The tops of the two connecting plates 631 are rotatably connected to pulleys 672 through fixed seats. The ropes 670 bypass the pulleys 671 and the pulleys 672. Limit members 673 are installed on both the support and the fixed seat, and the limit members 673 are used to limit the ropes 670 wound around the pulleys 671 and the pulleys 672.

[0049] When in the initial state, the rope 670 is in a slack state. When the bending pressing head 8 contacts the plate 9, the rope 670 is in a taut state. Then, the bending pressing head 8 continues to drive the auxiliary shaping pressing frame 63 to move downward. The auxiliary shaping pressing frame 63 drives the pulley two 672 to move downward. The pulley two 672 pulls the supporting panel 60 pushed by the swing rod 623 through the rope 670 to assist in flipping, so as to avoid the problem that the width dimension of the supporting panel 60 is relatively long, the swing rod 623 is relatively close to the hinge of the supporting panel 60, and it is difficult for the swing rod 623 to push the supporting panel 60 to flip.

[0050] Refer to Figure 3 、 Figure 4 and Figure 5 , the positioning component 64 includes a positioning insertion rod 640 installed at the bottom of the connecting plate 631. The positioning insertion rod 640 slides up and down through the supporting base 5. A pressing and cooperating component for driving the lifting plate 624 to move downward in cooperation is installed between the lower end of the positioning insertion rod 640 and the lifting plate 624.

[0051] Refer to Figure 3 and Figure 5 , the pressing and cooperating component is a supplementary cylinder 642 installed at the lower end of the lifting plate 624 and arranged along the length direction of the lifting plate 624. The supplementary cylinder 642 corresponds to the insertion rod one by one. A through groove communicating with the supplementary cylinder 642 is opened on the lifting plate 624.

[0052] The positioning insertion rod 640 slides up and down through the supporting base 5 to guide the up and down movement of the auxiliary shaping pressing frame 63. At the same time, the supplementary cylinder 642 is inserted and cooperated with the positioning insertion rod 640, so as to increase the movable distance when the positioning insertion rod 640 moves downward, and also enable the positioning insertion rod 640 to move upward without separating from the supporting base 5. When the positioning insertion rod 640 moves downward, it pushes the supplementary cylinder 642 to drive the lifting plate 624 to move downward.

[0053] Refer to Figures 1 - 6 , during operation, the plate 9 is horizontally placed on the supporting panel 60, and the plate 9 is horizontally pushed so that the bent part of the plate 9 enters between the bending pressing head 8 and the supporting base 5.

[0054] Then, the lifting drive source drives the connecting frame 7 to drive the bending pressing head 8 to move downward to bend the sheet 9. The connecting frame 7 drives the auxiliary shaping pressing frame 63 to move downward. The positioning assembly 64 cooperates with the supporting base 5 to guide the up-and-down movement of the auxiliary shaping pressing frame 63. When the bending pressing head 8 contacts the sheet 9, the positioning assembly 64 cooperates with the synchronous flipping connection group 62. When the bending pressing head 8 presses the sheet 9 to bend and enters the V-shaped surface of the supporting base 5, the synchronous flipping connection group 62 drives the supporting panel 60 and the support bar 61 to rotate along their respective hinge points until the supplementary panels 66 on the supporting panel 60 and the support bar 61 are aligned with the corresponding inclined surfaces in the V-shaped surface of the supporting base 5 and assist in supporting the two end faces of the sheet 9 bent at 90 degrees. There is no need for manual assistance for the bent sheet 9, which improves the convenience of bending the sheet 9 into shape. At the same time, it can cooperate with the auxiliary shaping pressing frame 63 to press and shape the two ends of the sheet 9 bent at 90 degrees, thereby improving the quality of bending the sheet 9 into shape.

[0055] After that, the lifting drive source drives the connecting frame 7 to drive the bending pressing head 8 to move upward, and the supporting panel 60 and the support bar 61 return to their original positions. The sheet 9 is taken out manually or by an external manipulator, the next end face is rotated, and the four sides of the sheet 9 are successively bent and formed (as Figure 6 shown).

[0056] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "vertical", "horizontal", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0057] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected", "installed", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
