Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a bending machine that is easy to limit. Background Technology

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a support, a worktable and a clamping plate. The worktable is placed on the support and consists of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base consists of a housing, a coil and a cover plate. The coil is placed in the recess of the housing and the top of the recess is covered by the cover plate.

[0003] In the use of existing bending machines, the sheet metal is subjected to strong pressure from the upper die during the bending process, which easily causes lateral slippage. Due to the lack of effective lateral restraint on the sheet metal, the slippage will cause the bending line to deviate from the preset position, resulting in the size and shape of the bent sheet metal not meeting the design requirements and affecting the bending quality. Therefore, a bending machine that is easy to limit is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a bending machine that facilitates positioning, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bending machine that facilitates positioning, comprising a bending machine body, an operating table on one side of the bending machine body, a lower die installed on one side of the operating table, and an upper die on the top of the lower die;

[0006] Two limiting plates are provided on one side of the operating table, and the limiting plates are used to limit the side of the bent sheet material.

[0007] The bending machine body has a movable component on one side for adjusting the spacing between the limiting plates, and a disassembly and assembly component on the other side for disassembling the limiting plates.

[0008] The moving component includes a rotating shaft, and the outer side of the rotating shaft is provided with two threaded sections with opposite directions of rotation, and a vertical plate is threadedly connected to the outer side of the threaded sections;

[0009] The assembly / disassembly assembly includes a sliding plate, with a pull rod and a locking rod fixed to each side of the sliding plate.

[0010] Preferably, the top of the vertical plate is provided with a second limiting groove adapted to the outside of the limiting plate, and the inside of the vertical plate is provided with a second sliding groove.

[0011] Preferably, the slide plate is slidably connected to the inner side of the second slide groove, and a spring is connected between the second slide groove and the slide plate.

[0012] Preferably, the limiting plate has a locking groove on one side of its bottom. When the locking rod is inserted into the locking groove, the limiting plate is in a fixed state. When the locking rod leaves the locking groove, the limiting plate is in a disassembled state.

[0013] Preferably, the pull rod extends movably through one side of the vertical plate, and a cover plate located on the side of the spring is connected to one side of the vertical plate by screws.

[0014] Preferably, the operating table has a first limiting groove inside, and the inner wall of the first limiting groove has two first sliding grooves. The outer side of the limiting plate is slidably connected to the inner side of the first sliding groove.

[0015] Preferably, as described above, a servo motor is fixed to one side of the bending machine body, the output shaft of the servo motor is fixed to the end of the rotating shaft, two guide rods are fixed to the inner wall of the first limiting groove, and the vertical plate is slidably connected to the outside of the guide rods through a linear bearing.

[0016] Preferably, the outer side of the rotating shaft is rotatably connected to the inner side of the first limiting groove, a maintenance door located on one side of the vertical plate is installed on the outer side of the bending machine body, and baffles are fixed on both sides of the operating table of the bending machine body.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0018] During the bending process, the sheet material may slide laterally due to the pressure of the upper die, causing the bending line to deviate from the preset position. However, the two limiting plates set on one side of the operating table ensure that the sheet material is always aligned with the back gauge positioning point through physical constraints, effectively preventing the sheet material from moving laterally and thus ensuring the bending quality.

[0019] When processing plates of different widths, the distance between the two limit plates is adjusted by starting the servo motor. The output shaft of the servo motor drives the rotating shaft to rotate. The two threaded sections on the outer side of the rotating shaft with opposite directions are threaded to the vertical plates, so that when the rotating shaft rotates, the two vertical plates can move towards or away from each other along the axis of the rotating shaft, thereby controlling the distance between the limit plates. This makes it easy to adapt to the processing of plates of various widths, greatly enhancing the versatility and applicability of the equipment.

[0020] Pull the lever to one side to retract the locking rod, making room for the installation of the limiting plate. Then, place the limiting plate in a specific way to achieve initial positioning. After it is fully inserted, release the lever. Under the action of the spring, the locking rod returns to its original position and inserts into the locking groove to complete the fixation. The entire installation process is clear and simple to operate. No complicated tools or professional skills are required. The installation of the limiting plate can be completed quickly, which greatly saves installation time and labor costs and improves work efficiency. Attached Figure Description

Example

[0030] Please see Figure 1-5 This utility model provides a technical solution: a bending machine with easy positioning, including a bending machine body 1. The bending machine body 1 is equipped with a grating ruler, a proportional valve, a gear pump, and a back gauge mechanism (not shown in the figure). An operating table 7 is provided on one side of the bending machine body 1, and a lower die 6 is installed on one side of the operating table 7. An upper die 5 is provided on the top of the lower die 6. The bending blade of the upper die 5 cooperates with the V-groove of the lower die 6. The pressure causes the sheet metal to undergo plastic deformation. The power source for pushing the upper die 5 downward can be a hydraulic cylinder or an oil cylinder. Two limiting plates 2 are provided on one side of the operating table 7. The limiting plates 2 are used to limit the side of the bent sheet metal. During the bending process, the sheet metal may slide laterally under the pressure of the upper die 5, causing the bending line to deviate from the preset position. The limiting plate 2 ensures that the sheet metal is always aligned with the back gauge positioning point through physical constraints. The sheet metal is placed on the lower mold 6 with its sides tightly against the two limiting plates 2. The limiting plates 2 are made of metal with a hard chrome plating or a wear-resistant coating to resist long-term friction and impact. A polyurethane or nylon block can be placed on the side in contact with the sheet metal to reduce scratches on the sheet metal surface. The upper mold 5 is driven to press down by a hydraulic cylinder or oil cylinder, which cooperates with the V-groove of the lower mold 6 to plastically deform the sheet metal. The limiting plates 2 constrain the lateral sliding of the sheet metal to ensure that the bending line is always aligned with the back gauge positioning point. The height of the limiting plates 2 can be set differently according to different sheet metals.

[0031] The bending machine body 1 has a moving component 3 on one side for adjusting the spacing of the limit plates 2. By adjusting the spacing of the limit plates 2, it is possible to quickly process plates of different widths. The moving component 3 has a disassembly and assembly component 9 on one side for disassembling the limit plates 2. The disassembly and assembly component 9 facilitates the maintenance and upgrading of the limit plates 2.

[0032] The moving component 3 includes a rotating shaft 35. Two oppositely threaded sections 37 are provided on the outer side of the rotating shaft 35. Vertical plates 36 are threadedly connected to the outer sides of the threaded sections 37. When the servo motor 31 starts, it drives the rotating shaft 35 to rotate. The two oppositely threaded sections 37 on the rotating shaft 35 respectively engage with the two vertical plates 36. When the rotating shaft 35 rotates, the two vertical plates 36 slide synchronously along the guide rod 33. Lead screw guards are fitted onto the outer sides of both the rotating shaft 35 and the guide rod 33. The lead screw guards are respectively connected to the inner side of the first limiting groove 34 and one side of the vertical plate 36.

[0033] The operating table 7 has a first limiting groove 34 inside, and two first sliding grooves 32 are provided on the inner wall of the first limiting groove 34. The outer side of the limiting plate 2 is slidably connected to the inner side of the first sliding groove 32. A servo motor 31 is fixed on one side of the bending machine body 1. The output shaft end of the servo motor 31 is fixed to the end of the rotating shaft 35. Two guide rods 33 are fixed on the inner wall of the first limiting groove 34. The vertical plate 36 is slidably connected to the outer side of the guide rods 33 through a linear bearing. The vertical plate 36 drives the limiting plate 2 to move through the second limiting groove 97 at the top. At the same time, the bottom of the limiting plate 2 slides along the first sliding groove 32 of the operating table 7 to realize the spacing adjustment.

[0034] The outer side of the rotating shaft 35 is rotatably connected to the inner side of the first limiting groove 34. A maintenance door 8 located on one side of the vertical plate 36 is installed on the outer side of the bending machine body 1. The maintenance door 8 provides an internal maintenance passage. Baffles 4 are fixed on both sides of the operating table 7 of the bending machine body 1. A switch group is installed on one side of the bending machine body 1. The output end of the switch group is electrically connected to the input end of the servo motor 31.

[0035] The assembly / disassembly component 9 includes a slide plate 94. A pull rod 91 and a locking rod 95 are fixed on both sides of the slide plate 94 respectively. A second limiting groove 97 adapted to the outside of the limiting plate 2 is opened at the top of the vertical plate 36. A second sliding groove 92 is opened inside the vertical plate 36. The slide plate 94 is slidably connected to the inside of the second sliding groove 92. A spring 93 is connected between the second sliding groove 92 and the slide plate 94. The spring 93 pushes the slide plate 94 to move towards the limiting plate 2.

[0036] A locking groove 96 is provided on one side of the bottom of the limiting plate 2. When the locking rod 95 is inserted into the inner side of the locking groove 96, the limiting plate 2 is in a fixed state. When the locking rod 95 leaves the inner side of the locking groove 96, the limiting plate 2 is in a disassembled state. The locking rod 95 of the slide plate 94 is inserted into the locking groove 96 at the bottom of the limiting plate 2 to complete the mechanical locking. The pull rod 91 is manually pulled outward to make the slide plate 94 compress the spring 93 and move backward. Then the locking rod 95 is removed from the locking groove 96. Finally, the limiting plate 2 can be removed from the second limiting groove 97. The pull rod 91 moves through one side of the vertical plate 36. A cover plate 10 located on the side of the spring 93 is connected to one side of the vertical plate 36 by screws. The cover plate 10 closes the spring 93. The spring 93 can be replaced by removing the cover plate 10.

[0037] In this embodiment, the bending machine body 1 is a model WC67K-100 / 2500 manufactured by Nantong Fuma Heavy Machine Tool Manufacturing Co., Ltd.; the servo motor 31 is model HG-JR353, manufactured by Mitsubishi Electric. The servo motor 31 is self-locked by an electrical signal, so that the output shaft end of the servo motor 31 has a brake structure. Since the structure and operating principle of the bending machine body 1 and the servo motor 31 of this model are existing technologies, their structure and operating principle will not be described in detail here.

[0038] Working principle: When the bending machine body 1 is working, the plate to be bent is placed on the operating table 7 and its side is pressed against the back gauge mechanism for initial positioning. The bending machine is started and the power source pushes the upper die 5 to move downward. The bending knife of the upper die 5 cooperates with the V-groove of the lower die 6 to apply pressure to the plate, causing the plate to undergo plastic deformation and complete the bending action.

[0039] During the bending process, the sheet material may slide laterally under the pressure of the upper die 5, causing the bending line to deviate from the preset position. At this time, the two limit plates 2 set on one side of the operating table 7 play a role in ensuring that the sheet material is always aligned with the back gauge positioning point through physical constraints, preventing the sheet material from moving laterally and ensuring bending accuracy.

[0040] When different widths of sheet metal need to be processed, the servo motor 31 is started. The output shaft of the servo motor 31 drives the rotating shaft 35 to rotate. Since the outer side of the rotating shaft 35 is provided with two threaded sections 37 with opposite directions of rotation, and the outer side of the threaded section 37 is threadedly connected to the vertical plate 36, when the rotating shaft 35 rotates, the two vertical plates 36 will move towards or away from each other along the axial direction of the rotating shaft 35. At the same time, the two guide rods 33 fixed to the inner wall of the first limiting groove 34, the vertical plate 36 is slidably connected to the outer side of the guide rods 33 through linear bearings. The guide rods 33 play a guiding role to ensure the smooth movement of the vertical plate 36. As the vertical plate 36 moves, it drives the limiting plate 2 installed on the vertical plate 36 to move, thereby adjusting the distance between the two limiting plates 2 to adapt to the processing requirements of sheet metal of different widths.

[0041] Pull the lever 91 to one side. The lever 91 drives the slide plate 94 to slide inside the second slide groove 92. At the same time, the spring 93 is compressed, causing the locking rod 95 to retract, leaving space for the installation of the limiting plate 2. Align the bottom of the limiting plate 2 with the second limiting groove 97 on the top of the vertical plate 36, which is adapted to the outer side of the limiting plate 2. The outer side of the limiting plate 2 is slidably connected to the inner side of the first slide groove 32 on the inner wall of the first limiting groove 34 inside the operating table 7 to achieve initial positioning. After the limiting plate 2 is completely placed into the second limiting groove 97, release the lever 91. Under the elastic force of the spring 93, the slide plate 94 drives the locking rod 95 to return to its original position. When the locking rod 95 is inserted into the locking groove 96 on one side of the bottom of the limiting plate 2, the limiting plate 2 is in a fixed state, and the installation is completed.

[0042] Pull the lever 91 to one side. The lever 91 causes the slide plate 94 to slide inside the second slide groove 92. At the same time, the spring 93 is compressed, causing the locking lever 95 to leave the inside of the locking groove 96. At this time, the limiting plate 2 is in the disassembled state. Remove the limiting plate 2 from the second limiting groove 97 and the first slide groove 32 to complete the disassembly, which facilitates the maintenance and upgrading of the limiting plate 2.

[0043] The maintenance door 8 is located on the outside of the bending machine body 1 and on one side of the vertical plate 36, which facilitates the inspection and maintenance of internal components such as the moving component 3. The baffle 4 is fixed on both sides of the operating table 7 of the bending machine body 1, which serves as a safety protection to prevent sheet metal or other objects from flying out and injuring people during the bending process. The switch group is installed on one side of the bending machine body 1 and is used to control the start, stop and other operations of the bending machine. The output end of the bending machine body 1 is electrically connected to the input end of the servo motor 31. The operation of the servo motor 31 can be controlled by the switch group, thereby controlling the adjustment of the distance between the moving component 3 and the limit plate 2.

[0044] In summary, during the bending process, the sheet material may slide laterally due to the pressure of the upper die 5, causing the bending line to deviate from the preset position. However, the two limiting plates 2 set on one side of the operating table 7 ensure that the sheet material is always aligned with the back gauge positioning point through physical constraints, effectively preventing the sheet material from moving laterally, thereby ensuring the bending quality.

[0045] When processing plates of different widths, the distance between the two limit plates 2 is adjusted by starting the servo motor 31. The output shaft of the servo motor 31 drives the rotating shaft 35 to rotate. The two threaded sections 37 on the outer side of the rotating shaft 35 with opposite directions are threadedly connected to the vertical plate 36, so that when the rotating shaft 35 rotates, the two vertical plates 36 can move towards or away from each other along the axis of the rotating shaft 35, thereby controlling the distance between the limit plates 2. This makes it easy to adapt to the processing of plates of various widths, greatly enhancing the versatility and applicability of the equipment.

[0046] Pull the lever 91 to one side to retract the locking lever 95, making room for the installation of the limiting plate 2. Then, place the limiting plate 2 in a specific manner to achieve initial positioning. After it is fully inserted, release the lever 91. Under the action of the spring 93, the locking lever 95 returns to its original position and inserts into the locking groove 96 to complete the fixation. The entire installation process is clear and simple to operate, requiring no complicated tools or professional skills. It can quickly complete the installation of the limiting plate 2, greatly saving installation time and labor costs and improving work efficiency.
