Embodiment 1

[0035] refer to Figure 1 to Figure 2, a lower notch angle compensation device for a bending machine, comprising an angle compensation mechanism 1, a lower die mold 2, an adjustment mechanism 3 and a moving base 4, an adjustment mechanism 3 is installed on the upper end of the movement base 4, and the adjustment mechanism 3 and the angle compensation The mechanism 1 is connected to each other, and the angle compensation mechanism 1 is connected to the lower die mold 2; the angle compensation mechanism 1 includes a panel 11, a central shaft 12, a U-shaped bracket 13 and a hydraulic cylinder 14, and the lower end of the panel 11 is fixedly connected with a central shaft 12, U The middle part of the lower end of the U-shaped bracket 13 is rotatably connected with the central axis 12, and the upper end of the U-shaped bracket 13 is connected with the panel 11 through the hydraulic cylinder 14; the lower end of the U-shaped bracket 13 extends downward to form side ears 15, and the t...

Embodiment approach

[0039] refer to Figure 7 , in order to better demonstrate the implementation process of the lower notch angle compensation device for bending machines, this embodiment now proposes an implementation method for the lower notch angle compensation device for bending machines, including the following steps:

[0040] S101: The driving mechanism drives the main sliding plate 42 to slide to the right end of the lower mold 2 until the projection of the angle compensation mechanism 1 along the vertical direction is located at the right end of the lower mold 2;

[0041] S102: the adjustment mechanism 3 drives the angle compensation mechanism 1 to move downward until the central axis 12 is aligned with the notch 21; specifically, the lifting cylinder 31 in the adjustment mechanism 3 drives the angle compensation mechanism 1 to move downward;

[0042] S103: The driving mechanism drives the main sliding plate 42 to slide to the left end of the lower die 2 until the central axis 12 is comp...

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that in this embodiment, a wedge block 23 is added, and the position between the lower mold 2 and the panel 11 is fixed by the wedge block 23, thereby improving the V-shaped groove in the process of bending the workpiece. Compressive performance, and at the same time can avoid misalignment between the lower die mold 2 and the panel 11.

[0046] refer to Figure 8 , the top wall of the lower mold 2 and the lower inner wall of the panel 11 are provided with oblique conical teeth 22, and a wedge block 23 is provided between the lower mold 2 and the panel 11, and the outer surface of the wedge block 23 is provided with The obliquely tapered groove 24 , the obliquely tapered groove 24 and the obliquely tapered teeth 22 engage with each other.

[0047] refer to Figure 9 , in order to better demonstrate the implementation process of the lower notch angle compensation device for bending machines, this embodiment now ...

Abstract

The invention discloses a lower notch angle compensation device for a bending machine and an implementation method of the lower notch angle compensation device, and belongs to the technical field of notch angle compensation. The problem that the notch angle of the bending machine cannot be adjusted is solved. The lower notch angle compensation device comprises an angle compensation mechanism, a lower mold, an adjusting mechanism and a moving base, the adjusting mechanism is arranged at the upper end of the moving base, the adjusting mechanism is connected with the angle compensation mechanism, and the angle compensation mechanism is connected with the lower mold; and the angle compensation mechanism comprises a panel, a middle shaft, a U-shaped support and a hydraulic cylinder, the lower end of the panel is fixedly connected with the middle shaft, the middle of the lower end of the U-shaped support is rotationally connected with the middle shaft, and the upper end of the U-shaped support is connected with the panel through the hydraulic cylinder. The angle of a bending groove is adjusted through stretching and retracting of the hydraulic cylinder, the complexity of replacing the bending groove is reduced, and the bending efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of notch angle compensation, in particular to a lower notch angle compensation device for a bending machine and an implementation method thereof. Background technique [0002] The bending machine is a machine capable of bending thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is composed of a seat shell, a coil and a cover plate, the coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into various workpiece requ...
