Description

Technical Field

[0001] This utility model belongs to the field of CNC bending machines, specifically relating to a CNC bending machine that is easy to adjust the angle. Background Technology

[0002] CNC bending machines use equipped dies to bend cold metal sheets into workpieces of various geometric cross-sectional shapes. Designed for cold-rolled sheet metal processing, they are widely used in sheet metal bending in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles. CNC bending machines achieve high-precision processing by precisely controlling the bending angle.

[0003] For example, in the Chinese utility model with announcement number CN219817580U and titled "A CNC bending machine that facilitates adjustment of bending angle", although the bending degree of the workpiece can be adjusted by adjusting the distance between the first and second mold blocks, only the lower mold is adjusted and the upper mold is not adjusted, which will lead to loss of control over the bending angle accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed CNC bending machine that is easy to adjust the angle in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A CNC bending machine with adjustable angle includes a base, a first adjustment component fixedly connected to the upper surface of the base, a connecting plate rotatably connected to the upper surface of the base, a first support plate fixedly connected to the side of the connecting plate, and a second adjustment component provided at the bottom of the first support plate.

[0007] As a further optimization of this utility model, a hydraulic cylinder is fixedly connected to the rear side of the base, and the output end of the hydraulic cylinder is rotatably connected to the connecting plate.

[0008] As a further optimization of this utility model, the first adjustment component includes a second support plate fixedly connected to the upper surface of the base. A servo motor is fixedly connected to the side wall of the second support plate. A bidirectional threaded rod that is rotatably connected to the inner wall of the second support plate is fixedly connected to the output end of the servo motor. Two threaded blocks that are slidably connected to the inner wall of the second support plate are threaded at both ends of the bidirectional threaded rod. A first lower mold base that is slidably connected to the upper surface of the second support plate is fixedly connected to the upper surface of one of the threaded blocks, and a second lower mold base that is slidably connected to the upper surface of the second support plate is fixedly connected to the upper surface of the other threaded block.

[0009] As a further optimization of this utility model, a sliding rod is fixedly connected to the inner wall of the second support plate, and two sliders that are slidably connected to the inner wall of the second support plate are slidably sleeved on the outer side of the sliding rod. The upper surface of one of the sliders is fixedly connected to the bottom of the first lower mold base, and the other slider is fixedly connected to the bottom of the second lower mold base.

[0010] As a further optimization of this utility model, the second adjustment component includes a V-shaped groove fixedly connected to the side of the first support plate. Two connecting rods slide through the inner wall of the V-shaped groove. One end of one connecting rod is fixedly connected to a first upper mold base, and one end of the other connecting rod is fixedly connected to a second upper mold base. Limiting plates are slidably connected to the outer sides of both connecting rods. A third support plate is fixedly connected to the side of the first support plate. An electric push rod is fixedly connected to the upper surface of the third support plate, and the output end of the electric push rod is fixedly connected to the upper surface of the limiting plate.

[0011] As a further optimization of this utility model, a plurality of positioning holes are provided on the upper surface of the second support plate, and positioning rods are inserted into the positioning holes.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the limiting plate is moved by an electric push rod, and the distance between the first upper die base and the second upper die base is moved by the cooperation of the V-groove, the limiting plate and the connecting rod, so as to adjust the angle between the first upper die base and the second upper die base, which facilitates bending different steel plates and other raw materials at different angles.

[0014] 2. The bidirectional threaded rod and threaded block are moved by a servo motor. The distance between the first lower mold base and the second lower mold base is changed by the cooperation of the bidirectional threaded rod, threaded block, slide rod and slider, so as to facilitate the change of the angle between the first lower mold base and the second lower mold base.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 , Figure 2 As shown, a CNC bending machine with adjustable angle includes a base 1, a hydraulic cylinder 2 fixedly connected to the rear side of the base 1, a connecting plate 3 rotatably connected to the upper surface of the base 1, the output end of the hydraulic cylinder 2 rotatably connected to the connecting plate 3, a first support plate 4 fixedly connected to the side of the connecting plate 3, and a first adjustment component 5 fixedly connected to the upper surface of the base 1. The hydraulic cylinder 2 pushes the connecting plate 3 to move, and the connecting plate 3 pushes the first support plate 4 to move, which facilitates subsequent bending operations on raw materials such as steel plates.

[0025] like Figure 3As shown, the first adjustment component 5 includes a second support plate 501 fixedly connected to the upper surface of the base 1. A servo motor 508 is fixedly connected to the side wall of the second support plate 501. In this embodiment, the servo motor 508 is model 80ST-07530, but it can be changed according to the actual situation. A bidirectional threaded rod 502 is fixedly connected to the output end of the servo motor 508. The bidirectional threaded rod 502 is rotatably connected to the inner wall of the second support plate 501. Two threaded blocks 503 are threadedly sleeved at both ends of the bidirectional threaded rod 502. Both are slidably connected to the inner wall of the second support plate 501. A first lower mold base 506 is fixedly connected to the upper surface of one threaded block 503, and the first lower mold base 506 is slidably connected to the upper surface of the second support plate 501. A second lower mold base 507 is fixedly connected to the upper surface of the other threaded block 503, and the second lower mold base 507 is slidably connected to the upper surface of the second support plate 501. A servo motor 508 drives the two threaded blocks 503 to move relative to each other. This relative movement of the threaded blocks 503 facilitates subsequent changes to the first lower mold base 506 and the second lower mold base 507. The distance between the bases 507 facilitates subsequent bending operations at different angles. Two threaded blocks 503 drive the middle sections of the first lower die base 506 and the second lower die base 507 to move. Both sides of the bidirectional threaded rod 502 are equipped with sliding rods 504 fixedly connected to the inner wall of the second support plate 501. Two sliders 505, slidably connected to the inner wall of the second support plate 501, are slidably sleeved on the outer side of the sliding rods 504. The upper surface of one slider 505 is fixedly connected to the bottom of the first lower die base 506, and the other slider 505 is fixedly connected to the second lower die base 507. The bottom is fixedly connected. The relative movement of the slider 505 drives the first lower mold base 506 and the second lower mold base 507 to move on both sides, so as to prevent the first lower mold base 506 and the second lower mold base 507 from tilting on both sides. The upper surface of the second support plate 501 is provided with several positioning holes 7. Positioning rods 8 are inserted into the positioning holes 7. The positions of the first lower mold base 506 and the second lower mold base 507 are fixed by the cooperation of the positioning holes 7 and the positioning rods 8, so as to prevent the positions of the first lower mold base 506 and the second lower mold base 507 from shifting during the bending process.

[0026] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, a second adjustment assembly 6 is provided at the bottom of the first support plate 4. The second adjustment assembly 6 includes a V-groove 602 fixedly connected to the side of the first support plate 4. Two connecting rods 604 slide through the inner wall of the V-groove 602, allowing movement within the V-groove 602 for subsequent position adjustment. One end of one connecting rod 604 is fixedly connected to a first upper mold base 605, and one end of the other connecting rod 604 is fixedly connected to a second upper mold base 606. The outer sides of both connecting rods 604 are slidably connected to the inside of the limiting plate 603. A third support plate 601 is fixedly connected to the side of the support plate 4. An electric push rod 607 is fixedly connected to the upper surface of the third support plate 601. The output end of the electric push rod 607 is fixedly connected to the upper surface of the limiting plate 603. The electric push rod 607 pushes the third support plate 601 to move. Then, it moves inside the V-groove 602 and the limiting plate 603 through the connecting rod 604. This facilitates the adjustment of the angle between the first upper die holder 605 and the second upper die holder 606, and facilitates the adjustment of the distance between the first lower die holder 506 and the second lower die holder 507, thereby improving the bending accuracy.

[0027] It should be noted that in the operation of this CNC bending machine with easy angle adjustment, the operator drives the bidirectional threaded rod 502 to rotate via the servo motor 508. The rotation of the bidirectional threaded rod 502 drives the two threaded blocks 503 to move relative to each other. The two threaded blocks 503 respectively drive the first lower die holder 506 and the second lower die holder 507 to move, thereby adjusting the distance between the first lower die holder 506 and the second lower die holder 507, which facilitates the adjustment of the angle between the lower dies.

[0028] Then, the limit plate 603 is moved by the electric actuator 607. The movement of the limit plate 603 causes the connecting rod 604, the first upper mold base 605 and the second upper mold base 606 to slide in the V-groove 602, which facilitates the adjustment of the angle between the upper mold bases. After the angle is adjusted, the connecting plate 3, the first support plate 4, the first upper mold base 605 and the second upper mold base 606 are moved by the hydraulic cylinder 2, which facilitates bending the steel plate at different angles.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
