Description

An anti-deviation feeding device for ultra-high precision sheet metal bending machines Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to an anti-deviation feeding device for an ultra-high precision sheet metal bending machine. Background Technology

[0002] A sheet metal bending machine is a piece of equipment used for processing sheet metal. It uses specific molds and pressure systems to bend flat sheet metal materials into various angles and shapes, such as V-shapes and U-shapes, to meet the styling requirements of different industrial products for sheet metal parts.

[0003] In existing sheet metal bending operations, sheet metal bending machines play a crucial role. However, a prominent problem exists when performing bending operations: deviation. When the bending machine begins bending the sheet metal, various factors, such as insufficient equipment precision, wear of mechanical parts, slight deviations in mold installation, or external interference during operation, can cause the sheet metal to deviate from the predetermined bending trajectory. Once such deviation occurs, it becomes impossible to complete the precise bending as required by the design, ultimately resulting in the bending operation failing to achieve the expected results. To address this, we propose an anti-deviation feeding device for ultra-high precision sheet metal bending machines. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that there is a prominent issue when performing bending operations: the tendency for misalignment to occur.

[0005] To address the aforementioned technical problems, this application provides an anti-deviation feeding device for an ultra-high precision sheet metal bending machine, including a base and further comprising:

[0006] A lifting seat is provided on top of a base. Four hydraulic cylinders are fixedly connected between the lifting seat and the base. A bending seat is fixedly connected to the top of the base, and a bending blade is fixedly connected to the bottom of the lifting seat. The bending seat and the bending blade cooperate to perform bending.

[0007] Support plates, two of which are fixedly connected to the two sides of the base respectively, and a horizontal plate is fixedly connected between the two support plates. Two grooves are opened on the top of the horizontal plate.

[0008] An anti-deviation unit is disposed on the top of the horizontal plate. The anti-deviation unit includes a first hydraulic rod, a second hydraulic rod, and a first plate. The two first plates clamp and limit the workpiece. The first hydraulic rod and the second hydraulic rod drive the two first plates to rotate accordingly, thereby adapting to the bending angle.

[0009] In some embodiments, the anti-deviation unit includes two first hydraulic rods disposed on the top of the horizontal plate. The two first hydraulic rods are respectively disposed at both ends of the horizontal plate. The two ends of the two first hydraulic rods are respectively rotatably connected to a first rotating joint and a second rotating joint. The top of the two first rotating joints is fixedly connected to a first plate body. The bottom of the two second rotating joints extends into a groove. The outside of the two grooves is fixedly connected to a second hydraulic rod. The driving end of the two second hydraulic rods extends into the groove and is fixedly connected to the second rotating joint. The top of the first plate body is provided with a plurality of clamping members.

[0010] In some embodiments, the clamping member includes a damping rod fixedly connected to the top of the first plate, a frame fixedly connected to the top of the damping rod, a clamping wheel rotatably connected inside the frame, and a spring sleeved on the damping rod.

[0011] In some embodiments, the horizontal plate and the anti-deviation unit are configured as two sets, and the two sets of the horizontal plate and the anti-deviation unit are arranged opposite to each other.

[0012] In some embodiments, a conveying unit is provided at the top of the horizontal plate for feeding the workpiece for bending. The conveying unit is configured in two sets, which are arranged opposite to each other.

[0013] In some embodiments, the conveying unit includes three third hydraulic rods fixedly connected to the top of the horizontal plate, the drive ends of the three third hydraulic rods being fixedly connected to a second plate, the second plate having two rectangular slots extending through it, and drive components being provided at both ends of the horizontal plate.

[0014] In some embodiments, the driving component includes a motor fixedly connected to the outside of the cross plate, two driving wheels rotatably connected inside the rectangular groove, and the driving end of the motor extending into the rectangular groove and fixedly connected to the two driving wheels.

[0015] This utility model has at least the following beneficial effects:

[0016] By setting up an anti-deviation unit, the plate-shaped workpiece is pushed between two first plates. The workpiece first contacts the upper and lower clamping parts. The clamping wheels compress the damping rod according to the workpiece thickness to avoid damage from hard contact. After being pushed towards the bending seat, the hydraulic cylinder is activated to bend the workpiece. Simultaneously, the first hydraulic rod is activated to rotate the first plate, limiting deviation and adapting to the angle. After bending, the bending angle can also be controlled. In addition, a conveying unit is added to activate the third hydraulic rod to clamp the workpiece. Then, the motor drives the drive wheel to move it, realizing automatic feeding. In short, this device can achieve automatic feeding while avoiding deviation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model. Embodiment 1

[0025] Please refer to Figures 1-6. This utility model provides a technical solution:

[0026] An anti-deviation feeding device for an ultra-high precision sheet metal bending machine includes a base 1, and further includes: a lifting seat 11, a support plate 2, and an anti-deviation unit 3. The lifting seat 11 is located on the top of the base 1, and four hydraulic cylinders 12 are fixedly connected between the lifting seat 11 and the base 1. A bending seat 13 is fixedly connected to the top of the base 1, and a bending blade 14 is fixedly connected to the bottom of the lifting seat 11. The bending seat 13 and the bending blade 14 cooperate to perform bending. Two support plates 2 are fixedly connected to both sides of the base 1, and a horizontal plate 21 is fixedly connected between the two support plates 2. Two grooves 22 are opened on the top of the horizontal plate 21. The anti-deviation unit 3 is located on the top of the horizontal plate 21. The anti-deviation unit 3 includes a first hydraulic rod 31, a second hydraulic rod 35, and a first plate 34. The two first plates 34 clamp and limit the workpiece. The first hydraulic rod 31 and the second hydraulic rod 35 drive the two first plates 34 to rotate accordingly, thereby adapting to the bending angle.

[0027] The anti-deviation unit 3 includes two first hydraulic rods 31 set at the top of the horizontal plate 21. The two first hydraulic rods 31 are respectively set at both ends of the horizontal plate 21. The two ends of the two first hydraulic rods 31 are respectively rotatably connected to a first rotating joint 32 and a second rotating joint 33. The top of the two first rotating joints 32 is fixedly connected to a first plate body 34. It should be noted that the position of the two first plate bodies 34 is higher than that of the bending seat 13 so that bending can be performed.

[0028] The bottoms of the two second rotating joints 33 extend into the grooves 22, and the two grooves 22 are fixedly connected to the outside of the two second hydraulic rods 35. The driving ends of the two second hydraulic rods 35 extend into the grooves 22 and are fixedly connected to the second rotating joints 33. The top of the first plate 34 is provided with multiple clamping parts 36. By setting the second hydraulic rods 35, the position of the first hydraulic rod 31 can be adjusted. It cooperates with the first hydraulic rod 31 to drive the first plate 34 to rotate.

[0029] The clamping member 36 includes a damping rod 361 fixedly connected to the top of the first plate 34. A frame 362 is fixedly connected to the top of the damping rod 361. A clamping wheel 363 is rotatably connected inside the frame 362. A spring 364 is sleeved on the damping rod 361. The horizontal plate 21 and the anti-deviation unit 3 are set in two sets. The two sets of horizontal plates 21 and anti-deviation units 3 are arranged opposite to each other. By setting the spring 364, the clamping wheel 363 can be quickly returned to its original position.

[0030] In use, the plate-shaped workpiece is pushed between the two first plates 34. The workpiece first contacts the upper and lower sets of clamping members 36. The clamping wheels 363 inside the two sets of clamping members 36 contact the workpiece and can compress the damping rod 361 according to the thickness of the workpiece, thereby avoiding damage from hard contact. Then, the workpiece is pushed to the top of the bending seat 13 by the upper and lower sets of clamping wheels 363. Then, the hydraulic cylinder 12 is activated to drive the lifting seat 11 to descend, which drives the bending cutter 14 to descend and cooperate with the bending seat 13 to bend. At this time, the workpiece will be bent at a certain angle. During this process, the upper and lower sets of first hydraulic rods 31 are activated simultaneously, which drives the upper and lower first plates 34 to rotate accordingly. Since the bending seat 13 is provided with a set of anti-deviation unit 3, support plate 2 and cross plate 21 on both sides, the two ends of the workpiece can be limited to avoid deviation. At the same time, it can adapt to the bending angle. In addition, after the bending is completed, the first hydraulic cylinder 12 can be activated again to control the bending angle of the workpiece. Example 2

[0031] Please refer to Figures 1 and 6. This utility model provides a technical solution:

[0032] Unlike Embodiment 1, the top of the horizontal plate 21 is provided with a conveying unit 4 for feeding the workpiece in for bending. The conveying unit 4 is configured in two sets, which are arranged opposite to each other.

[0033] The conveying unit 4 includes three third hydraulic rods 41 fixedly connected to the top of the horizontal plate 21. The driving ends of the three third hydraulic rods 41 are fixedly connected to the second plate 42. Two rectangular slots 43 are opened through the second plate 42. Both ends of the horizontal plate 21 are provided with driving components 44.

[0034] The driving component 44 includes a motor 441 fixedly connected to the outside of the horizontal plate 21, and two driving wheels 442 rotatably connected inside the rectangular groove 43. The driving end of the motor 441 extends into the rectangular groove 43 and is fixedly connected to the two driving wheels 442. It should be noted that both sides of the bending seat 13 are provided with conveying units 4, and the driving direction of the motors 441 in the two sets of conveying units 4 is the same to avoid interference.

[0035] By adding a conveying unit 4, firstly, the upper and lower sets of third hydraulic rods 41 are activated, which can drive the two second plates 42 to move relative to each other and clamp the plate-shaped workpiece. Then, the motor 441 is activated, which drives the drive wheel 442 to rotate, thereby driving the workpiece to move. In conjunction with the anti-deviation unit 3, automatic feeding is achieved.
