Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet processing equipment, and in particular to a hydraulic bending and forming device suitable for metal sheets. Background Technology

[0002] Metal sheets are commonly used in the construction industry, such as curtain walls, ceilings, partitions, and railings. They are also widely used in manufacturing industries such as aerospace, automobile manufacturing, and home appliance manufacturing. Hydraulic bending is one of the important processing technologies for metal sheets.

[0003] Existing hydraulic bending and forming devices for metal sheets require manual control of the bending length and angle, resulting in significant dimensional errors in the bending process, reduced work efficiency, and impact on the usability of the sheets. Therefore, this invention proposes a hydraulic bending and forming device for metal sheets that differs from existing technologies to address these technical problems. Utility Model Content

[0004] To address the aforementioned issues of large dimensional errors in sheet metal bending, reduced work efficiency, and impact on sheet metal usability, this invention provides a hydraulic bending and forming device suitable for metal sheets.

[0005] This utility model provides a hydraulic bending and forming device suitable for metal sheets, which adopts the following technical solution:

[0006] A hydraulic bending and forming device for metal sheets includes a transverse plate, an upper processing frame installed on the periphery of the upper surface of the transverse plate, a plurality of sets of strip holes opened on the upper surface of the upper processing frame, a plurality of sets of sliding units installed on the upper processing frame, upper bending components that penetrate the strip holes installed at the plurality of sets of sliding units, a lower bending component installed on the upper surface of the transverse plate, and an angle adjustment unit installed on the lower bending component.

[0007] The metal sheet is bent by the cooperation of the upper bending component and the lower bending component, and the angle of the lower bending component can be changed by the angle adjustment unit.

[0008] By adopting the above technical solution, the metal sheet to be processed is placed above two sets of bending forming plates. The sliding unit is activated by the existing PLC or other control unit to drive the upper bending assembly to move horizontally. The upper bending assembly is also activated to cooperate with the lower bending assembly to perform hydraulic bending of the metal sheet. Simultaneously, the two sets of angle adjustment units are activated to adjust the included angle between the two sets of bending forming plates, which is convenient to meet the different bending angle processing requirements of the metal sheet.

[0009] Optionally, the sliding unit includes an electric slide rail, which is fixed to the upper surface of the upper processing frame, and an electric slider is mounted on the outside of the electric slide rail.

[0010] Optionally, the upper bending assembly includes a second cylinder frame, which is fixed to the outer wall of the electric slider. A second telescopic cylinder is installed at the top of the inner cavity of the second cylinder frame, and the output shaft of the second telescopic cylinder passes through the strip hole and is fixed with a bending forming roller.

[0011] Optionally, the lower bending assembly includes a lower processing frame, which is fixed to the upper surface of the transverse plate. Rotating rods are installed at both ends of the upper surface of the lower processing frame. The top ends of multiple sets of rotating rods are hinged to bending forming plates via hinge shafts. An anti-overstretching unit is installed on the upper surface of the lower processing frame and fixed to the lower surface of the bending forming plate.

[0012] By adopting the above technical solution, the second telescopic cylinder is activated to extend and retract to different sizes, thereby driving the bending forming roller to move downward to the corresponding height to perform hydraulic bending of the metal sheet. The electric slide rail is activated to drive multiple sets of electric sliders to move synchronously, thereby driving the second cylinder frame, the second telescopic cylinder and the bending forming roller to move horizontally synchronously, so that the metal sheet is gradually bent and fully fits between the two sets of bending forming plates, so that the bending angle of the metal sheet is the same as the angle between the two sets of bending forming plates.

[0013] Optionally, the angle adjustment unit includes a first cylinder frame, which is fixed on the lower processing frame. A first telescopic cylinder is installed at the bottom of the inner cavity of the first cylinder frame, and the output shaft of the first telescopic cylinder passes through the top wall of the lower processing frame and is fixed with an arc-shaped plate.

[0014] By adopting the above technical solution, the two sets of first telescopic cylinders are activated simultaneously to move the arc plate up and down. Under the action of the steering wheel, the bending and forming plate can be rotated, thereby adjusting the included angle between the two sets of bending and forming plates, which is convenient for processing metal plates with different bending angles.

[0015] Optionally, the anti-overstretch unit includes a steering wheel and a transverse tube. The steering wheel and the transverse tube are respectively installed on the upper surface of the lower processing frame. A spring is installed in the inner cavity of the transverse tube. A connecting block is installed at the end of the spring. A steel wire rope is installed on the outer wall of the connecting block, which is wound around the outside of the steering wheel and fixed to the lower surface of the bent forming plate.

[0016] By adopting the above technical solution, the connecting block can be driven to move horizontally in the inner cavity of the transverse tube under the elastic force of the spring. Thus, under the action of the steering wheel, the wire rope can pull the bending forming plate to rotate at the top of the rotating rod through the hinge shaft. This allows adjustment of the included angle between the two sets of bending forming plates, preventing the rotation angle between the two sets of bending forming plates from being too large.

[0017] Optionally, baffles are welded to both the front and rear sides of the upper surface of the lower processing rack to prevent the metal sheet from accidentally slipping away from the bending and forming plate.

[0018] By adopting the above technical solution, the metal sheet to be processed can be blocked by the two sets of baffles, so that the metal sheet may accidentally separate from the bending and forming plate during the processing.

[0019] In summary, this utility model has at least one of the following beneficial effects:

[0020] The simultaneous activation of two sets of first telescopic cylinders allows the curved plate to move up and down. Under the elastic force of the spring, the bending and forming plate can be rotated by the steel wire rope, thereby adjusting the included angle between the two sets of bending and forming plates, which is convenient for processing metal sheets with different bending angles.

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0025] Example 1: This example provides a hydraulic bending and forming device suitable for metal sheets, such as... Figure 1 and 2As shown, this invention can solve the problem of large dimensional errors in sheet metal bending, which reduces work efficiency and affects the use of the sheet metal. It includes a horizontal sheet 10, with an upper processing frame 1 installed on the outer periphery of the upper surface of the horizontal sheet 10. The lateral longitudinal section of the upper processing frame 1 is set as an inverted U-shape. Multiple sets of strip holes 15 are opened on the upper surface of the upper processing frame 1. Multiple sets of sliding units are installed on the upper processing frame 1. The sliding units include electric slide rails 19, which are fixed on the upper surface of the upper processing frame 1. Electric sliders 20 are installed on the outside of the electric slide rails 19. Multiple sets of electric sliders 20 are equipped with upper bending components. The upper bending components include a second cylinder frame 16, which is fixed on the outer wall of the electric slider 20.

[0026] Combination Figure 1 and 2 In an embodiment of this utility model, a second telescopic cylinder 17 is installed at the top of the inner cavity of the second cylinder frame 16. The output shaft of the second telescopic cylinder 17 passes through the strip hole 15 and is fixed with a bending forming roller 18. A lower bending assembly is installed on the upper surface of the transverse plate 10. The lower bending assembly includes a lower processing frame 11, which is fixed on the upper surface of the transverse plate 10. The lower processing frame 11 is located inside the upper processing frame 1. Rotating rods 7 are installed at both ends of the upper surface of the lower processing frame 11. The top ends of multiple sets of rotating rods 7 are hinged to bending forming plates 13 through hinge shafts.

[0027] The metal sheet to be processed is placed above the two sets of bending forming plates 13. The second telescopic cylinder 17 is activated to extend and retract to different sizes, thereby driving the bending forming roller 18 to move downward to the corresponding height to perform hydraulic bending processing on the metal sheet. Multiple sets of electric slide rails 19 are controlled to drive multiple sets of electric sliders 20 to move synchronously, thereby driving the second cylinder frame 16, the second telescopic cylinder 17 and the bending forming roller 18 to move horizontally synchronously, so that the metal sheet is gradually bent and fully fits between the two sets of bending forming plates 13.

[0028] Combination Figure 1 and 2 In an embodiment of this utility model, an anti-overstretching unit is installed on the upper surface of the lower processing frame 11. The anti-overstretching unit includes a steering wheel 3 and a transverse tube 6. The steering wheel 3 and the transverse tube 6 are respectively installed on the upper surface of the lower processing frame 11. The steering wheel 3 is located on the outer side of the transverse tube 6. A spring 8 is installed in the inner cavity of the transverse tube 6. A connecting block 9 is installed at the end of the spring 8. A steel wire rope 12 is installed on the outer wall of the connecting block 9, which is wound around the outside of the steering wheel 3 and fixed to the lower surface of the bent forming plate 13.

[0029] Under the elastic force of the spring 8, the connecting block 9 can move horizontally in the inner cavity of the transverse tube 6. Thus, under the action of the steering wheel 3, the wire rope 12 pulls the bending forming plate 13 to rotate at the top of the rotating rod 7 through the hinge shaft, thereby avoiding an excessively large included angle between the two sets of bending forming plates 13.

[0030] Combination Figure 1 and 2 In this embodiment of the invention, an angle adjustment unit is installed on the lower bending assembly. The angle adjustment unit includes a first cylinder frame 4, which is fixed on the lower processing frame 11. A first telescopic cylinder 5 is installed at the bottom of the inner cavity of the first cylinder frame 4. The output shaft of the first telescopic cylinder 5 passes through the top wall of the lower processing frame 11 and is fixed with an arc-shaped plate 2. The upper surface of the arc-shaped plate 2 contacts the lower surface of the bending forming plate 13. By simultaneously activating the two sets of first telescopic cylinders 5 to extend and retract, the arc-shaped plate 2 can be moved up and down, causing the bending forming plate 13 to rotate at the top of the rotating rod 7 via the hinge shaft. This allows adjustment of the included angle between the two sets of bending forming plates 13, making it convenient to meet the different bending angle processing requirements of metal sheets.

[0031] Combination Figure 1 and 2 In this embodiment of the invention, baffles 14 are welded to both the front and rear sides of the upper surface of the lower processing frame 11. Both sets of baffles 14 are located on the outer sides of the bending forming roller 18 and the bending forming plate 13. Under the action of the two sets of baffles 14, the metal sheet to be processed can be blocked, thereby preventing the metal sheet from accidentally separating from the bending forming plate 13 during the processing.

[0032] Working principle: When using this hydraulic bending and forming device suitable for metal sheets, the device is stably placed using the transverse plate 10. The metal sheet to be processed is placed above the two sets of bending and forming plates 13. The second telescopic cylinder 17 is activated by the existing PLC or other control unit to extend and retract to different sizes, thereby driving the bending and forming roller 18 to move downward to the corresponding height. The hydraulic pressure of the second telescopic cylinder 17 drives the bending and forming roller 18 to perform hydraulic bending processing on the metal sheet.

[0033] At this time, multiple sets of electric slide rails 19 are controlled to drive multiple sets of electric sliders 20 to move synchronously, thereby driving the second cylinder frame 16, the second telescopic cylinder 17 and the bending forming roller 18 to move horizontally synchronously, so that the metal sheet is gradually bent and fully fits between the two sets of bending forming plates 13, so that the bending angle of the metal sheet is the same as the angle between the two sets of bending forming plates 13.

[0034] The simultaneous activation of two sets of first telescopic cylinders 5 extends and retracts, thereby driving the arc plate 2 to move up and down. Under the elastic force of the spring 8, the connecting block 9 can move horizontally within the inner cavity of the transverse tube 6. Thus, under the action of the steering wheel 3, the wire rope 12 pulls the bending forming plate 13 to rotate at the top of the rotating rod 7 through the hinge shaft, thereby adjusting the included angle between the two sets of bending forming plates 13. This is convenient for processing metal sheets with different bending angles. Under the action of the two sets of baffles 14, the metal sheet to be processed can be blocked, thus preventing the metal sheet from accidentally separating from the bending forming plate 13 during processing.
