Problems solved by technology
[0007] However, this existing registered proposal is to use hydraulic pressure to load and unload the punch. Although the operation is relatively easy, the length of the punch is equivalent to the length of the bending machine, which is not only very long, but also heavy.
Therefore, it is necessary to maintain the state of moving the punch downward for replacement during replacement, which still has the original danger.
In addition, the following configuration is not clearly proposed, that is, the operation of the hydraulic device to make the adapter press the punch

The present invention relates to a device to attach and detach a bending blade of a bending machine, to be mounted on a bending machine bending or forming a steel plate, and, more specifically, relates to a device to attach and detach a bending blade of a bending machine, capable of preventing an accident likely to occur during replacement of the bending blade, facilitating the replacement of thebending blade, and surely fixating the bending blade. To achieve this, a protrusion is formed on a front cover and a groove corresponding to the protrusion is formed on the bending blade, thereby being able to perform the replacement by inserting the bending blade from a side surface of the bending machine. A hydraulic device is used for fixating or removing the bending blade, and a piston operated by hydraulic pressure pushes the bending blade through a rear cover, thereby rotating a lower part of the front cover forward and backward by a fastening bolt while pressing a spring, to fixate or remove the bending blade.
Description
technical field [0001] The present invention relates to a bending blade loading and unloading device of a bending machine installed on a bending machine for bending or forming iron plate articles. Specifically, it is a bending blade loading and unloading device for a bending machine that can prevent possible accidents when changing the bending blade and can ensure that the bending blade is easily replaced and the bending blade is fixed firmly. Background technique [0002] Generally speaking, a bending blade is installed on a bending machine that bends an iron plate object according to a prescribed shape, and the iron plate object can be bent by means of the bending blade, so that the iron plate object can be bent according to the required shape. bend. [0003] It is for this reason that the bending blade must be replaced every time according to the bending shape of the iron plate item to be bent. In addition, when the bending blade is worn due to friction and precision ma...
