Description

Technical Field

[0001] This utility model relates to the field of bending machine lower die front support technology, specifically a high-precision front support angle magnetic positioning device and lower die structure for bending machines. Background Technology

[0002] The bending accuracy and angle accuracy of the workpiece to be processed by the bending machine directly depend on the angle positioning device in front of it. Because the bending angle of the workpiece is different, the traditional processing method of sheet metal processing enterprises is to draw a line once, place the workpiece on the lower die and bend it once to form a bending angle.

[0003] This cannot meet the requirements of batch positioning, angle accuracy, and work efficiency, and the angle accuracy of the traditional bending method is also not high.

[0004] For example, CN202211286550.5 describes a front support frame for a bending machine and a bending machine, which includes a front support frame to support workpieces.

[0005] Furthermore, as exemplified by CN202023061943.5, the angle positioning device for the front support of a bending machine uses an arc-shaped vernier fixed below one side of the upper plate of the tray, which is detachably installed on the lower die of the bending machine. This allows the angle positioning ruler, which is rotatably installed on the upper plate of the tray, to be positioned inside the arc-shaped vernier. The locking device at the bottom of the tray then locks and positions the angle positioning ruler after the angle has been adjusted, effectively solving the problem of the high processing difficulty of bending parts with angle requirements.

[0006] However, the following problems exist:

[0007] 1) The angle positioning device is fixed to the side of the lower mold with bolts. Disassembly requires loosening the bolts.

[0008] 2) The comparative document states that the knob set screw passes through the tray to tighten or loosen the angle positioning ruler. The friction limit is achieved by rotating the end of the set screw to move and abut against it. The limiting constraint force is small. It is easy for the workpiece to come into contact with the angle positioning ruler and generate angular rotational displacement.

[0009] 3) Before each bending, the workpiece needs to be marked and aligned. The marking is the bending position, and the alignment is to place the marked position parallel to the bending groove. Therefore, the production efficiency of bending the workpiece is not high.

[0010] To address these issues, we provide a high-precision front support angle magnetic positioning device and lower die structure for a bending machine. Utility Model Content

[0011] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-precision front support angle magnetic positioning device and lower die structure for bending machines, so as to solve the technical problem that the angle and position alignment of workpiece bending cannot be done quickly and effectively.

[0012] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-precision front support angle magnetic positioning device for a bending machine, including a support base located on one side of the lower die, an installation port is provided in the support base and a suction cup electromagnet is installed thereon, and the installation port is set towards the lower die.

The adjusting component adjusts the included angle between the sheet metal backing plate and the support plate and constrains the placement angle of the workpiece. The side of the workpiece moves and abuts against the side of the sheet metal backing plate that is away from the support plate.

[0015] In a further technical solution, a lateral connecting plate is installed between the lower mold and the support base. One end of the lateral connecting plate is fixedly connected to the lower mold, and the other end is locked to the support base by lateral bolts.

[0016] In a further technical solution, the top of the angle scale plate is flush with the top of the lower mold.

[0017] In a further technical solution, the adjusting component includes a connecting plate one and a connecting plate two, one end of each connecting plate one and the connecting plate two is located on the support plate and connected to each other by a mounting positioning bolt one; the other end of each connecting plate one and the connecting plate two are fixed to the plate abutment by a mounting positioning bolt two.

[0018] The length of the first connecting plate is less than the length of the second connecting plate, and the first connecting plate is located on the side of the second connecting plate closer to the lower mold.

[0019] In a further technical solution, the connecting plate 2 has a waist-shaped groove, and a positioning bolt 1 is installed in the waist-shaped groove; the support plate has a fixing hole and is threadedly connected to the positioning bolt 1.

[0020] In a further technical solution, the support plate is also provided with a guide groove, which is perpendicular to the lower mold; the connecting plate is constrained in the guide groove by a corresponding positioning bolt; the other end of the connecting plate is provided with two sets of position holes and one set of mounting positioning bolts is detachably connected to the plate backing plate.

[0021] In a further technical solution, two sets of support bases and angle scale plates are respectively installed at both ends of the lower mold, and the two sets of angle scale plates are symmetrically distributed.

[0022] A high-precision lower die structure for a bending machine includes a high-precision front support angle magnetic positioning device installed on one side of the lower die and a limiting component installed on the other side of the lower die. The limiting component is used to constrain the top movement position of the workpiece placed on the lower die.

[0023] In a further technical solution, the limiting component includes a limiting base plate and a positioning plate. A mounting base is installed at the bottom of the lower mold. The limiting base plate is installed on the side of the mounting base facing away from the support base. A fixing plate and a positioning plate are respectively provided on the limiting base plate. The positioning plate slides on the limiting base plate. The fixing plate and the limiting base plate are fixedly connected and located on the side of the positioning plate facing away from the lower mold.

[0024] A limit screw is installed between the positioning plate and the fixing plate. The limit screw is threadedly connected to the fixing plate and its end is connected to the positioning plate through a mounting bearing.

[0025] In a further technical solution, the height of the positioning plate is higher than the height of the angle scale plate; the positioning plate is in movable contact with the workpiece.

[0026] In this device, the support plate serves to fix and connect; connecting plate one connects the support plate and the sheet metal support plate, allowing them to move together; connecting plate two connects the support plate and the sheet metal support plate, allowing them to move together; the sheet metal support plate serves as a reference support for the sheet metal.

It has the function of attracting objects when energized and not attracting objects when de-energized; the angle scale plate is used to indicate the placement angle of the workpiece; the support base is used to fix and install the suction cup DC electromagnet; the lateral positioning plate is used to fix the support base and provide lateral positioning.

[0027] Compared with existing technologies, it has the following beneficial effects:

[0028] This utility model is divided into a left angle positioner and a right angle positioner. It relies on an electric suction cup type DC electromagnet to act on the side of the mold. By adjusting the plate backing plate, the angle required by the customer can be bent, effectively meeting the requirements of convenient disassembly, angle accuracy, work efficiency, and batch positioning.

[0029] This utility model achieves the support effect through the second connecting plate, and the waist-shaped groove on the second connecting plate can realize the long-distance adjustment of the second connecting plate; simultaneously, the movement of the first connecting plate on the guide groove can also realize the long-distance adjustment; simultaneously, the installation of a washer on the first positioning bolt can realize the locking constraint, which is used to maintain the angle constraint of the plate against the support plate, thereby ensuring that the placement angle of the workpiece has good certainty.

[0030] This utility model uses a limiting base plate installed on the side of the mounting base; a limiting screw is installed on the limiting base plate, which can move the positioning plate relative to the fixed plate by a certain distance to limit the end position of the workpiece, thereby realizing the quick confirmation of the angle and position of the workpiece. Therefore, it can quickly locate the bending position without drawing lines, which is suitable for operators on the assembly line to quickly perform bending, and is conducive to large-scale and efficient production.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Example 1

[0047] like Figure 1-5 As shown, this is one embodiment of the present invention: a high-precision front support angle magnetic positioning device for a bending machine, as follows. Figure 1 As shown, it includes a front support angle magnetic suction component located on one side of the lower mold 9. The front support angle magnetic suction component includes a support base 7. The support base 7 has an installation port and a suction cup electromagnet 5 is installed inside it. The installation port is set towards the lower mold 9.

[0048] An angle scale plate 6 is mounted on the support base 7, and the upper surface of the angle scale plate 6 is marked with angle graduations. Two sets of support bases 7 and angle scale plates 6 are respectively mounted on both ends of the lower mold 9, and the two sets of angle scale plates 6 are symmetrically distributed, allowing for the simultaneous bending of at least two sets of workpieces. Figure 1 The left side is set up for angle positioning, including the left angle scale plate, support base, and adjustment components; the right side is set up for the right angle locator, including the right angle scale plate, adjustment components, and support base.

[0049] like Figure 1 As shown, a support plate 1 and a sheet metal abutment 4 are vertically mounted on an angle scale plate 6. The support plate 1 is fixedly mounted on the angle scale plate 6. An adjusting component is installed between the sheet metal abutment 4 and the support plate 1. The adjusting component adjusts the included angle between the sheet metal abutment 4 and the support plate 1 and constrains the placement angle of the workpiece 10. The side of the workpiece 10 movably abuts against the side of the sheet metal abutment 4 facing away from the support plate 1. The adjusting component can configure the sheet metal abutment to be hinged at one end and detachably connected and fixed at the other end using connecting rods of different sizes.

[0050] like Figure 2 As shown, a lateral connecting plate 8 is installed between the lower mold 9 and the support base 7. One end of the lateral connecting plate 8 is fixedly connected to the lower mold 9, and the other end is locked to the support base 7 by lateral bolts. The top of the angle scale plate 6 is flush with the top of the lower mold 9.

[0051] This invention guides the installation angle of the workpiece by setting an angle scale plate, such as... Figure 4 As shown, by pre-drawing lines, the installation position of the workpiece is determined, enabling the workpiece to bend along different bending lines to form... Figure 5 The finished workpiece. This utility model has the advantage of quickly determining the installation angle of the workpiece. This utility model adjusts and fixes the included angle between the sheet metal backing plate and the support plate through an adjusting component.

[0052] Example 2

[0053] like Figure 6-10 As shown, this is another embodiment of the present invention, based on embodiment 1, as follows: Figure 6 As shown, the adjusting component includes a connecting plate 2 and a connecting plate 3. One end of the connecting plate 2 and the connecting plate 3 are located on the support plate 1 and connected to each other by a mounting positioning bolt 11; the other end is fixed to the plate backing plate 4 by a mounting positioning bolt 12.

[0054] The length of the connecting plate 2 is less than the length of the connecting plate 3, and the connecting plate 2 is located on the side of the connecting plate 3 closer to the lower mold 9.

[0055] like Figure 7 As shown, the connecting plate 2 3 has a waist-shaped groove 13, and a positioning bolt 11 is installed in the waist-shaped groove 13; the support plate 1 has a fixing hole 15 and is threadedly connected to the positioning bolt 11.

[0056] like Figure 8 As shown, the support plate 1 is also provided with a guide groove 14, which is perpendicular to the lower mold 9; the connecting plate 2 is constrained within the guide groove 14 by corresponding positioning bolts 11; as shown Figure 9 As shown, the other end of the connecting plate 2 is provided with two sets of position holes 16 and a set of mounting positioning bolts 12 are detachably connected to the plate backing plate 4. The support plate 1 can be fixed to the angle scale plate 6 by welding or bonding. The support plate is perpendicular to the lower mold.

[0057] like Figure 10 As shown, this embodiment differs from Embodiment 1 in its technical solution. It employs multiple sets of front support angle magnetic suction components, which can be installed on the same side of a single set of lower mold components. Although Figure 10The diagram shows five sets of front support angle magnetic chucks, but it is not limited to five sets; the number can be further expanded for actual production. This embodiment, by installing a large number of front support angle magnetic chucks, enables bending of multiple workpieces in a single operation, thereby overcoming the low efficiency of existing single-bending methods and achieving simultaneous bending of large batches of workpieces, greatly improving workpiece bending efficiency.

[0058] Working method: First, clean the sides of the lower mold 9 with gasoline, let it dry, and then wipe it clean with a dry cloth;

[0059] Then, the left and right angle positioners are placed on the side of the lower mold and flush with the upper plane of the lower mold by energizing the suction cup electromagnets, and the lateral bolts on the lateral positioning plate are tightened.

[0060] Pull the corresponding sheet metal backing plate according to the required angle to align the reference surface of the sheet metal backing plate with the angle value on the angle scale plate, and tighten the positioning bolts at the positions of connecting plate one and connecting plate two to fix them in place;

[0061] Using the sheet metal support plate as a reference, place the workpiece on the angle scale plate. After reaching the required angle dimension, press the foot switch to the angle required by the drawing, remove the workpiece, and use an angle ruler to check the dimensions according to the drawing requirements. Once the requirements are met, directly place the workpieces onto the positioners one by one according to the above process. After completing the required workpieces, turn off the suction cup electromagnet and remove the left and right angle positioners. This effectively meets the requirements of convenient disassembly, angle accuracy, work efficiency, and batch positioning.

[0062] Left and right angle positioners can meet the bending angle requirements of different workpieces. The suction cup electromagnet attracts objects when energized and disengages when de-energized, making it easy to disassemble, safe, reliable, and space-saving.

[0063] This utility model achieves the support effect through the second connecting plate, and the waist-shaped groove on the second connecting plate can realize the long-distance adjustment of the second connecting plate; simultaneously, the movement of the first connecting plate on the guide groove can also realize the long-distance adjustment; simultaneously, the installation of a washer on the first positioning bolt can realize the locking constraint, which is used to maintain the angle constraint of the plate against the support plate, thereby ensuring that the placement angle of the workpiece has good certainty.

The limiting screw 21 is threadedly connected to the fixing plate 19, and its end is connected to the positioning plate 20 via a mounting connection bearing 22. Figure 13 As shown.

[0067] like Figure 11 As shown, the height of the positioning plate 20 is higher than the height of the angle scale plate 6; the positioning plate 20 is in movable contact with the workpiece 10.

[0068] This utility model uses a limiting base plate installed on the side of the mounting base; a limiting screw is installed on the limiting base plate, which can move the positioning plate relative to the fixed plate by a certain distance to limit the end position of the workpiece, thereby realizing the quick confirmation of the angle and position of the workpiece.
