Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled hydraulic bending machines, in particular to a numerically controlled hydraulic bending machine with a protective device. Background Art

[0002] In the actual production process, steel pipes often need to be bent. Currently, bending is generally done manually with the help of tools. Although this bending method can meet the bending needs of some small steel pipes, CNC hydraulic bending can make up for the shortcomings of manual bending.

[0003] For example, the patent document with the announcement number CN 208195308 U discloses a steel pipe bending machine, the technical solution of which includes a workbench, a vertical rotating bracket is provided at one end of the workbench, a guide wheel is fixedly connected to the rotating bracket, a limit block and a clamping block are provided on one side of the guide wheel, the limit block is connected to the workbench, the clamping block is fixedly connected to the rotating bracket, a fixing device is provided on the workbench, the fixing device includes a vertical sliding rod slidably connected to the workbench and a cross bar slidably connected to the sliding rod, and a clamping mechanism is provided on the cross bar. The utility model can bend special-shaped steel pipes, prevent the existing steel pipe bending machine from rotating when bending special-shaped steel pipes, and improve the accuracy of the spatial angle when bending the steel pipe.

[0004] However, when this structure is used in pipe bending operations, it can often only perform stable limiting and fixing operations on the bending position of the pipe. It is impossible to perform proper limiting and protective operations on the end of the device that has completed the bending. When the pipe at the bending position breaks, the pipe is prone to flying out. It is impossible to perform safer and more reliable protective operations and meet daily use needs. Therefore, it is urgent to design a CNC hydraulic bending machine with a protective device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a CNC hydraulic bending machine with a protective device to solve the problem that the existing structure proposed in the above background technology can only perform stable limiting and fixing operations on the bending position of the pipe when applied to the pipe bending operation, and cannot perform proper limiting and protective operations on the end of the device that has completed the bending. When the pipe at the bending position breaks, the pipe is prone to flying out, and a safer and more reliable protective operation cannot be performed, which cannot meet the daily use needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC hydraulic bending machine with a protective device, comprising a bending frame, a movable track is arranged at the bottom of one end of the bending frame, a feeder seat is arranged on the surface of the movable track, and a supporting bottom plate is fixedly connected to the bottom of the other end of the bending frame;

[0007] A buffer cover is fixedly connected to the surface of the supporting base plate, and a buffer seat is movably connected inside the buffer cover.

[0008] Preferably, a connecting bottom block is fixedly connected to the bottom of the buffer seat, and movable shafts are arranged at both ends of the connecting bottom block.

[0009] Preferably, both ends of the connecting bottom block are movably connected with arc-shaped cover plates via a movable shaft, and the inner walls of the buffer seat, the connecting bottom block and the arc-shaped cover plate are all provided with protective rubber pads.

[0010] Preferably, one end of the two groups of arc-shaped cover plates is fixedly connected to a locking socket, and a locking bolt is provided on the surface of the locking socket.

[0011] Preferably, a damping rubber sleeve is provided on the inner wall of the buffer cover, and buffer springs are evenly provided inside the buffer cover.

[0012] Preferably, both sides of the bending machine frame are fixedly connected with limiting side plates, and the sides of the limiting side plates are provided with mounting covers.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The CNC hydraulic bending machine with protective devices can make the whole equipment perform safer and more reliable CNC hydraulic bending operations of pipes through the bending frame, moving rail, feeder base, supporting bottom plate, buffer cover, buffer seat, protective rubber pad, damping rubber sleeve and buffer spring. In actual use, the staff first fixes one end of the pipe to the inside of the feeder base, and then the pipe enters the inside of the bending frame through the feeder base along the moving rail, and then performs a rapid bending operation through the limiting side plates on the left and right sides of the bending frame and the bending equipment fixed by the limiting inside of the mounting cover. At this time, the bent end of the pipe can enter the inside of the buffer seat and the arc cover plate, and the protective limiting operation of the pipe can be performed through the protective rubber pad on the inner wall. At the same time, the buffer seat as a whole can perform stable buffer protection operation through the damping rubber sleeve and buffer spring inside the buffer cover, thereby providing more comprehensive protection for the overall bending process of the pipe, avoiding the problem of pipe breakage and splashing, and reflecting the practicality of the equipment design.

[0015] The CNC hydraulic bending machine with protective devices further improves the overall use effect of the equipment by setting a bending frame, a buffer seat, a connecting bottom block, a movable shaft, a curved cover plate, a protective rubber pad, a locking seat and a locking bolt. In daily use, when the pipe completes a safe bending process under the protection of the buffer seat and the curved cover plate, the locking bolt on the top of the locking seat can be unscrewed, and then the curved cover plates connecting the two ends of the bottom block can be rotated and unfolded along their respective movable axes, so that the buffer seat and the curved cover plate connected to the bending end of the bending frame can be quickly unfolded over a large range, ensuring that the pipe that has completed the bending operation can be quickly taken out, which reflects the comprehensiveness of the equipment design.
