In the process that the baffle block 3 moves downwards, the inclined plane on the outer side of the baffle block 3 can be in contact with the bending roller 9 and continuously move downwards, so that the friction force can be reduced, and when the side baffle is bent to the steel plate, the friction force between the side baffle and the steel plate can be reduced through the baffle roller 901, so that the side baffle can be bent conveniently.

As shown in fig. 5 and 13, an oil storage chamber 10 is arranged inside the baffle block 3, lubricating oil or drawing oil and the like can be stored in the oil storage chamber 10, an oil inlet 1001 is formed in the upper side of the baffle block 3, an oil outlet 1002 is formed in the lower side of the baffle block 3, two oil pouring ports 1003 are formed in the side pressure plate 201 in a penetrating mode, the oil pouring ports 1003 are located on the upper side of the baffle roller 901 which is close to the oil inlet 1001, and when the oil inlet 1001 and the oil pouring ports 1003 are not communicated, the lubricating oil in the oil storage chamber 10 cannot leak out.

Before processing, lubricating oil is poured into the oil storage cavity 10 manually, after the baffle block 3 is extruded by the baffle roller 901 towards the direction close to the middle pressing plate 203, the oil outlet 1002 on the baffle block 3 is communicated with the oil pouring port 1003 on the side pressing plate 201, so that the lubricating oil in the oil storage cavity 10 can flow into the bending roller 9 through the oil pouring port 1003 and the oil outlet 1002, the baffle block 3 can reset towards the reverse movement away from the middle pressing plate 203 when moving downwards into the baffle groove 303, then the oil outlet 1002 is not communicated with the oil pouring port 1003, and the steel plate can be better bent by pouring the lubricating oil on the baffle roller 901.

It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
