Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to an angle-adjustable bending machine. Background Technology

[0002] A bending machine is a machine that can bend thin plates. Its function is to press steel plates into parts of various shapes according to process requirements. Its working principle is that the power drives the pressure component downward, which closes with the bending and shaping groove below to achieve bending of the plate.

[0003] For example, utility model application CN202222410429.0 discloses a bending machine for iron products. This utility model, through the cooperation of a support component and a correction component, replaces manual correction of feeding and positioning deviations, thus improving the bending accuracy of iron products. The hook spring design allows the top block to return to a horizontal position via springback when the extrusion head moves away from the iron product. However, it can only bend iron products to a fixed angle, thus its use has certain limitations.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed an angle-adjustable bending machine. Utility Model Content

A rectangular opening is provided on the surface of the worktable 8, and the worktable 8 is in close contact with the bending mold 13 and the bending mold 2 14 respectively. The end of the connecting rod 15 away from the moving plate 7 is rotatably connected to the sliding block 11, and the end of the connecting rod 2 16 away from the moving plate 7 is rotatably connected to the sliding block 2 12. The sliding rod 1 9 and the sliding rod 2 10 are parallel to each other, and the sliding block 11 and the sliding block 2 12 are parallel to each other.

[0022] The specific operation is as follows: start the hydraulic cylinder 6 on the base 1, and drive the moving plate 7 to move up and down outside the support rod 2 through the hydraulic cylinder 6. Change the angle of the connecting rod 15 and the connecting rod 26, thereby adjusting the distance between the sliding block 11 and the sliding block 22. When the bending pressure piece 5 moves down to the appropriate position, workpieces with different bending angles are obtained.

[0023] like Figure 1 As shown, support rods 2 are fixed on both sides of the top of the base 1, and a top seat 3 is connected to the top of the support rods 2. A hydraulic cylinder 4 is installed in the middle of the top seat 3, and a bending pressure piece 5 is provided at the bottom of the hydraulic cylinder 4.
