Description

Technical Field

[0001] The invention belongs to the technical field of bending machines, and in particular relates to a machine base for a metal bending machine. Background Art

[0002] Under the pressure of the upper or lower die of the bending machine, the bent metal sheet first undergoes elastic deformation and then enters plastic deformation. In the initial stage of plastic bending, the sheet is free to bend. As the upper or lower die applies pressure to the sheet, the sheet and the inner surface of the V-groove of the lower die gradually come close to each other. At the same time, the radius of curvature and the bending arm gradually become smaller. Continue to apply pressure until the stroke ends, so that the upper and lower dies are in full contact with the sheet at three points. At this time, a V-shaped bend is completed, which is commonly known as bending. Metal bending operations are an essential part of many manufacturing processes. Bending operations are applied to a variety of different metal materials, including metal sheets, metal pipes or tubes, metal bars, etc.

[0003] Nowadays, in the process of bending metal pipes, it is first necessary to complete the clamping action of the metal pipe, so the force problem of the clamp needs to be considered. When the diameter of the metal pipe is large, the rigidity of the metal pipe is also large, and a larger torque is required to bend the metal pipe. At this time, the force acting on the two clamps of the clamp is significantly increased, and general clamps are difficult to meet the requirements. Moreover, when the metal pipe is large, its mass is also increased accordingly, and the weight borne by the bending machine base is also increased accordingly, which causes the stability of the bending machine to be reduced. As an important component of the bending machine, the bending machine base directly determines the bending accuracy and working life of the bending machine. Therefore, there are deficiencies and it cannot meet the user's use needs. Therefore, it is necessary to further improve it.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a machine base for a metal bending machine is provided, in order to achieve a purpose with more practical value. Summary of the invention

[0007] Furthermore, a movable main rod is fixedly installed at the bottom of the movable component, a movable plate is fixedly installed at the bottom end of the movable main rod, buffer connecting rods are movably installed on the left and right sides of the movable plate, and a buffer block is movably connected to the upper end of the buffer connecting rod; wherein the buffer block is arranged in the inner wall of the fixed machine base, and a buffer spring is arranged and connected between the buffer block and the inner wall of the fixed machine base, and by arranging the mutual coordinated movement among the buffer connecting rod, the buffer block and the buffer spring, the stability of the movable component and the movable plate when moving downward is effectively guaranteed, and the use effect of the device is further improved.

[0008] Furthermore, a buffer plate is fixedly installed at the bottom of the movable plate, and a pressure relief airbag is installed at the bottom of the inner wall of the fixed base, and the pressure relief airbag is arranged directly below the buffer plate; wherein, the buffer plate and the pressure relief airbag are used in combination, and the pressure is effectively absorbed by the pressure relief airbag, which can effectively reduce the bearing pressure of the fixed component on the metal pipe, and at the same time improve the service life of the equipment.

[0009] Furthermore, two supporting air cushions are installed between the fixed base and the bottom of the movable component. The two supporting air cushions are arranged on the left and right sides of the movable main rod. The supporting air cushions are arranged in a folded shape. The supporting air cushions can play a role in supporting the movable component.

[0010] Furthermore, racks are fixedly installed on both sides of the left and right sides of the movable part, and the outer side of the rack is meshed and connected with a driven gear.

[0014] Compared with the prior art, the present invention provides a machine base for a metal bending machine, which has the following beneficial effects: 1. The base of the metal bending machine drives the movable part to move downward through the fixed part based on the pressure generated by the metal pipe, and utilizes the driven gear to mesh with the rack on the outside of the movable part, so that the lower end of the reinforced telescopic rod is slowly opened outward, and the telescopic spring inside the reinforced main rod is used to push the telescopic connecting rod so that its bottom end is always in contact with the bottom of the inner wall of the shell, so that the fixed base increases the contact area with the bottom of the inner wall of the shell, and at the same time increases the force area, thereby improving the stability of the device, and at the same time can reduce its shaking during work, further improving the bending effect of the metal pipe.

[0015] 2. The base of the metal bending machine drives the driving slider to generate kinetic energy through external drive, so that the driving slider slides relatively on the fixed slide rod, and the driving slider moves while driving the bending reinforcement clamp to move synchronously, so that the bending reinforcement clamp is relatively closed, and the metal pipe is fixed and positioned at the same time, thereby fixing the metal pipe. By setting the length of the bending reinforcement clamp to be long enough, the bending reinforcement clamp fixes the metal pipe while increasing the contact area with the metal pipe, thereby increasing its force area during the bending process. On the one hand, the metal pipe is fixed more firmly, and on the other hand, its bending accuracy is effectively improved.

[0016] 3. For the base of the metal bending machine, when the metal tube is larger, its mass will increase accordingly, and the weight borne by the base of the bending machine will also increase accordingly. The pressure generated by the metal tube drives the movable part to move downward through the fixed part, and the buffer connecting rod is used to pull the buffer block, and the buffer spring is squeezed at the same time. The coordinated movement among the buffer connecting rod, the buffer block and the buffer spring effectively ensures the stability of the movable part and the movable plate when moving downward, further improving the use effect of the device.

[0017] 4. The base of the metal bending machine drives the buffer plate to move downward synchronously while the movable plate moves downward, and uses the buffer plate to squeeze and compress the pressure relief airbag. The pressure is effectively absorbed by setting the pressure relief airbag, which can effectively reduce the bearing pressure of the fixed parts on the metal pipe and improve the service life of the equipment.
