at this time, the unlocking rod moves in the direction close to the pawl 532 under the abutting of the limiting frame 14 and pushes the pawl 532 to separate from the ratchet 531, and in the process of separating from the ratchet 531, the ratchet 531 drives one end, close to each other, of the clamping plate 52 to rotate in the direction away from the side wall of the angle steel for a movement angle, the clamping plate 52 is separated from the angle steel, and when the mounting frame 51 moves in the direction away from the workbench 1, the first spring 533 drives the pawl 532 to reset and fix the ratchet 531 again, and the side wall of the angle steel limits the clamping plate 52, so that feeding is facilitated again.

The mounting bracket 51 moves in a direction approaching the table 1, at this time, the third spring 56 is stretched, and forms a trend of moving in a direction away from the table 1 for the connecting rod 54 and the pressing rod 57, at this time, the pressing rod 57 abuts against the inclined surface of the pressing rod 58 and presses the clamping plate 52 in a direction approaching each other, so that friction force between the clamping plate 52 and the side wall of the angle steel increases in the process of moving the angle steel, when the mounting bracket 51 moves in a direction away from the table 1, the third spring 56 gradually returns to deform, and the pressing force between the pressing rod 58 and the pressing rod 57 gradually disappears, so that the clamping plate 52 is convenient to clamp and separate from the angle steel without manual driving.

The implementation principle of the angle steel cutting machine in the embodiment of the application is as follows: the pushing plate 331 drives the angle steel to move towards the direction close to the workbench 1 until the end part of the angle steel is abutted against the clamping plate 52, and drives the angle steel to move continuously, at the moment, the end part of the angle steel drives the clamping plate 52 to rotate towards the direction far away from each other until the distance between the ends of the clamping plates 52 close to each other is equal to the width of the angle steel, at the moment, the clamping plate 52 clamps the angle steel and moves along with the angle steel to the side close to the workbench 1, the movement of the end part of the angle steel stops when passing through the lower side of the saw blade 11, and the saw blade 11 moves downwards and cuts off the end part of the angle steel, so that the uneven end part of the angle steel is cut off;

the clamping plate 52 is driven to separate from the angle steel and move in a direction away from the workbench 1 until the distance between the mounting frame 51 and the end part of the angle steel, which passes through the saw blade 11, is matched with the length to be sheared, at the moment, the clamping plate 52 clamps the side wall of the angle steel again, the pushing plate 331 pushes the angle steel to move and drives the mounting frame 51 to move in a direction close to the workbench 1 until the side wall of the mounting frame 51 abuts against the side wall of the workbench 1, and the saw blade 11 cuts the angle steel again to finish cutting.

The embodiment of the application also discloses a cutting process. The cutting process comprises the following steps:

s1, placing angle steel at one end of a conveying table 3 far away from a workbench 1, and driving the angle steel to move to one side close to the workbench 1 through a pushing plate 331 until the angle steel moves to a mounting frame 51;

s2, driving the angle steel to continuously move towards the direction close to the workbench 1, wherein at the moment, one end of the angle steel close to the workbench 1 passes through the mounting frame 51, the clamping plate 52 clamps the angle steel under the movement of the angle steel, and at the moment, the mounting frame 51 slides on the conveying table 3 along with the movement of the angle steel until the angle steel passes through the saw blade 11;

s3, stopping the movement of the angle steel, and enabling the saw blade 11 to move downwards and cut off the angle steel to finish cutting.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
