Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending machine technology, and in particular to an adjustment and positioning structure for a hydraulic bending machine. Background Technology
[0002] Hydraulic bending machines are widely used in workpiece bending operations due to their advantages of simple operation, low cost and fast response speed. A hydraulic bending machine generally includes a support, a worktable, a hydraulic drive system and a die. The support usually adopts a cantilever structure and is used for the first hydraulic cylinder. The hydraulic cylinder is controlled by its control system to control the movement of the die to complete the bending work.
[0003] In existing technology, such as the Chinese patent publication number CN212682123U, a CNC hydraulic bending machine with shock absorption function is disclosed. This machine includes a hydraulic bending machine body, inside which an electromagnetic control valve is installed. Below the electromagnetic control valve, a first hydraulic cylinder is installed. The electromagnetic control valve is connected to both the first and second hydraulic cylinders. The electromagnetic control valve is connected to a control device via a power supply connection. The second hydraulic cylinder is installed inside the first hydraulic cylinder, and a hydraulic rod is installed at the bottom of the second hydraulic cylinder. The first hydraulic cylinders are symmetrically distributed along the centerline of the hydraulic bending machine body. Beneficial effects: When replacing the shock absorption mechanism, the electric telescopic cylinder is disassembled. After prolonged use, the shock absorption spring gradually loses its elasticity, causing it to shorten. When the corresponding rod contacts and abuts against the secondary corresponding rod, the shock absorption mechanism needs to be replaced, thus ensuring the equipment has a long-lasting shock absorption effect.
[0004] When a hydraulic bending machine bends a workpiece, the workpiece is usually placed on a table, and the bending mechanism is extended and retracted by a cylinder to bend the workpiece. However, the workpiece needs to be adjusted and positioned during this process. If the positioning effect of the workpiece is not good, it will cause the workpiece to shift or tilt, thereby reducing the bending effect. Therefore, a hydraulic bending machine adjustment and positioning structure is needed to solve this problem. Utility Model Content
[0005] The purpose of this invention is to provide an adjustment and positioning structure for a hydraulic bending machine, which has the effect of adjusting and positioning the bent parts.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hydraulic bending machine adjustment and positioning structure, including a processing table and a base, wherein a bending groove is provided inside the processing table, roller plates are fixedly connected to both sides of the processing table, and a support roller is rotatably connected inside the roller plate, an L-plate is fixedly connected to both sides of the processing table, a cylinder plate is provided on the outer side of the L-plate, a rectangular feed groove is provided inside the cylinder plate, a first limiting groove is provided inside the L-plate, a cylinder is fixedly installed on the inner side of the cylinder plate, a push rod is provided at the output end of the cylinder, a pressure block is fixedly connected to one end of the push rod, a second limiting groove is provided inside the pressure block, and limiting rollers are rotatably connected inside both the first limiting groove and the second limiting groove.
[0007] By adopting the above technical solution, the cylinder plate is installed on the outside of the L-plate, and then the bent part is extended into the first limiting groove inside the L-plate through the rectangular feeding groove. The bent part is supported by two symmetrical rollers. During the feeding process, the friction and resistance of the bent part are reduced by the rotation of the two rollers, and the bent part is passed through the inside of the two L-plates and the cylinder plate. The part to be bent overlaps above the bending groove. Then the cylinder is activated, which drives the push rod and the pressure block to extend and retract. The pressure block descends, allowing another part of the bent part to extend into the inside of the second limiting groove. The first and second limiting grooves limit the bent part, preventing the bent part from shifting or shaking during the bending process. The bent part deforms during the bending process and will be displaced on the two symmetrical limiting rollers, thereby reducing the resistance and friction during the deformation process. This device can prevent the bent part from shifting or shaking during the bending process by adjusting and positioning the bent part.
[0008] A further feature of this invention is that a linear track is fixedly connected to the inner side of the cylinder plate, and the pressure block is slidably connected inside the linear track.
[0009] By adopting the above technical solution, the pressure block will move inside the linear track during the extension and retraction process. The linear track is linear in shape, which prevents the pressure block from shifting during the extension and retraction process.
[0010] A further feature of this invention is that a connecting plate is fixedly connected to the outside of the L-plate, and a groove is provided inside the cylinder plate.
[0011] By adopting the above technical solution, the groove is extended into the interior of the connecting plate, thereby allowing the cylinder plate to be installed on the outside of the L plate.
[0012] A further feature of this invention is that the cylinder plate is internally threaded with a screw pin, which extends into the interior of the connecting plate.
[0013] By adopting the above technical solution, the cylinder plate is fixed to the outside of the L plate with screws, which not only has a good fixing effect, but also makes it easy to disassemble the cylinder plate, thus facilitating maintenance.
[0014] A further feature of this invention is that the number of screw pins is eight, and the eight screw pins are arranged in groups of four, with each group of screw pins distributed in a rectangular array.
[0015] By adopting the above technical solution, since there are two cylinder plates, the eight screw pins are divided into two groups, with each group of screw pins distributed at the four corners of the cylinder plate.
[0016] A further feature of this invention is that the number of idlers is two, and the two idlers are symmetrical to each other.
[0017] By adopting the above technical solution, two rollers support the two sides of the middle part of the bent piece respectively.
[0018] A further feature of this invention is that a counterweight is fixedly connected inside the base.
[0019] By adopting the above technical solution, the counterweight is set on the inner bottom wall of the base, increasing the overall weight of the base.
[0020] A further feature of this invention is that a hydraulic cylinder is fixedly connected to the top of the counterweight, and a push rod is provided at the output end of the hydraulic cylinder.
[0021] By adopting the above technical solution, the hydraulic cylinder is activated, which drives the push rod to extend and retract.
[0022] A further feature of this invention is that a lifting seat is fixedly connected to the top of the top rod, and the lifting seat is fixedly connected to the bottom of the processing table.
[0023] By adopting the above technical solution, the top rod drives the lifting seat to extend and retract, thereby allowing the height of the processing table to be adjusted. By adjusting the height of the processing table, the distance between the bending machine and the processing table can be adjusted, improving the flexibility of bending operations.
[0024] A further feature of this invention is that both sides of the inner wall of the base are fixedly connected to a limiting rail, and the limiting rail is linear.
[0025] By adopting the above technical solution, the lifting seat will move inside the limit track during the lifting process, preventing the lifting seat from deviating.
[0026] The beneficial effects of this utility model are:
[0027] 1. This utility model, through the arrangement of a processing table, bending groove, roller plate, support roller, L-plate, cylinder plate, rectangular feed groove, first limiting groove, cylinder, push rod, pressure block, second limiting groove, and limiting roller, installs the cylinder plate on the outside of the L-plate. Then, the bent part extends through the rectangular feed groove into the first limiting groove inside the L-plate. Two symmetrical support rollers support the bent part. During the feeding process, the rotation of the two support rollers reduces friction and resistance, allowing the bent part to pass through the interior of the two L-plates and the cylinder plate. The bending point overlaps with the bending section. Above the bending groove, the cylinder is then activated, causing the cylinder to drive the push rod and pressure block to extend and retract. The pressure block descends, causing another part of the bent piece to extend into the interior of the second limiting groove. The first and second limiting grooves limit the bent piece, preventing it from shifting or wobbling during the bending process. The bent piece deforms during the bending process and will move on two symmetrical limiting rollers, thereby reducing the resistance and friction during the deformation process. This device can prevent the bent piece from shifting or wobbling during the bending process by adjusting and positioning it.
[0028] 2. This utility model, through the arrangement of the connecting plate, screw pin, base, counterweight, hydraulic cylinder, push rod, lifting seat, and limiting rail, extends the groove into the interior of the connecting plate, thereby allowing the cylinder plate to be installed on the outside of the L-plate. The cylinder plate is fixed to the outside of the L-plate by the screw pin, which not only provides a good fixing effect but also facilitates the disassembly of the cylinder plate for easy maintenance. Activating the hydraulic cylinder drives the push rod to extend and retract, which in turn drives the lifting seat to extend and retract, thereby allowing the height of the processing table to be adjusted. By adjusting the height of the processing table, the distance between the bending machine and the processing table can be adjusted, improving the flexibility of the bending operation.

[0036] Reference Figure 1-4A hydraulic bending machine adjustment and positioning structure includes a processing table 1 and a base 17. The processing table 1 has a bending groove 2 inside. Roller plates 3 are fixedly connected to both sides of the processing table 1. Support rollers 4 are rotatably connected inside the roller plates 3. L-plates 5 are fixedly connected to both sides of the processing table 1. A cylinder plate 6 is provided on the outer side of the L-plate 5. A rectangular feed groove 7 is provided inside the cylinder plate 6. A first limiting groove 8 is provided inside the L-plate 5. A cylinder 9 is fixedly installed on the inner side of the cylinder plate 6. A push rod 10 is provided at the output end of the cylinder 9. A pressure block 11 is fixedly connected to one end of the push rod 10. A second limiting groove 12 is provided inside the pressure block 11. Limiting rollers 13 are rotatably connected inside both the first limiting groove 8 and the second limiting groove 12. The cylinder plate 6 is installed on the outer side of the L-plate 5. The bent part is then extended through the rectangular feed chute 7 into the first limiting groove 8 inside the L-plate 5. Two symmetrical support rollers 4 support the bent part. During feeding, the rotation of the two support rollers 4 reduces friction and resistance, allowing the bent part to pass through the two L-plates 5 and the cylinder plate 6. The part to be bent overlaps above the bending groove 2. Then, the cylinder 9 is activated, driving the push rod 10 and the pressure block 11 to extend and retract. The pressure block 11 descends, causing another part of the bent part to extend into the second limiting groove 12. The first limiting groove 8 and the second limiting groove 12 limit the bent part, preventing it from shifting or wobbling during bending. The bent part deforms during bending. The component will be displaced on two symmetrical limiting rollers 13, thereby reducing resistance and friction during deformation. This device can prevent the bent component from shifting or wobbling during bending by adjusting and positioning it. A linear track 14 is fixedly connected to the inner side of the cylinder plate 6, and the pressure block 11 is slidably connected inside the linear track 14. The pressure block 11 will shift inside the linear track 14 during extension and retraction. The linear track 14 is linear in shape to prevent the pressure block 11 from shifting during extension and retraction. A connecting plate 15 is fixedly connected to the outside of the L plate 5. A groove is opened inside the cylinder plate 6, extending into the inside of the connecting plate 15, so that the cylinder plate 6 is installed on the outside of the L plate 5. A screw pin 1 is threadedly connected inside the cylinder plate 6. 6. The screw pins 16 extend into the interior of the connecting plate 15, fixing the cylinder plate 6 to the exterior of the L plate 5. This not only provides excellent fixation but also facilitates disassembly of the cylinder plate 6 for easy maintenance. There are eight screw pins 16, arranged in groups of four, forming a rectangular array. Since there are two cylinder plates 6, the eight screw pins 16 are divided into two groups, with each group located at one of the four corners of the exterior of the cylinder plate 6. There are two support rollers 4, symmetrically positioned to support both sides of the middle of the bent part. A counterweight 18 is fixedly connected inside the base 17, positioned on the inner bottom wall of the base 17 to increase its overall weight.A hydraulic cylinder 19 is fixedly connected to the top of the counterweight 18. A push rod 20 is installed at the output end of the hydraulic cylinder 19. Activating the hydraulic cylinder 19 drives the push rod 20 to extend or retract. A lifting seat 21 is fixedly connected to the top of the push rod 20, and the lifting seat 21 is fixedly connected to the bottom of the processing table 1. The push rod 20 drives the lifting seat 21 to extend or retract, thereby adjusting the height of the processing table 1. By adjusting the height of the processing table 1, the distance between the bending machine and the processing table 1 can be adjusted, improving the flexibility of the bending operation. Limiting rails 22 are fixedly connected to both sides of the inner wall of the base 17. The limiting rails 22 are linear. During the lifting process, the lifting seat 21 will move within the limiting rails 22, preventing the lifting seat 21 from shifting.
[0037] In this invention, the cylinder plate 6 is installed on the outer side of the L-plate 5. Then, the bent part is extended through the rectangular feed groove 7 into the first limiting groove 8 inside the L-plate 5. Two symmetrical support rollers 4 support the bent part. During feeding, the rotation of the two support rollers 4 reduces friction and resistance, allowing the bent part to pass through the interiors of the two L-plates 5 and the cylinder plate 6. The part to be bent overlaps above the bending groove 2. Then, the cylinder 9 is activated, causing the cylinder 9 to drive the push rod 10 and the pressure block 11 to extend and retract. The pressure block 11 descends, causing another part of the bent part to extend into the interior of the second limiting groove 12. The first limiting groove 8 and the second limiting groove 12 limit the bent part, preventing it from shifting or wobbling during bending. The bent part deforms during bending. The bent part will be displaced on two symmetrical limiting rollers 13, thereby reducing resistance and friction during deformation. This device can prevent the bent part from shifting or shaking during bending by adjusting and positioning the bent part. The groove extends into the interior of the connecting plate 15, so that the cylinder plate 6 is installed on the outside of the L plate 5. The cylinder plate 6 is fixed to the outside of the L plate 5 by the screw pin 16, which not only has a good fixing effect, but also makes it easy to disassemble the cylinder plate 6, achieving the effect of easy maintenance. The hydraulic cylinder 19 is started, so that the hydraulic cylinder 19 drives the push rod 20 to extend and retract. The push rod 20 drives the lifting seat 21 to extend and retract, thereby allowing the height of the processing table 1 to be adjusted. By adjusting the height of the processing table 1, the distance between the bending machine and the processing table 1 can be adjusted, improving the flexibility of bending operation.
