The size of the collet 3154 is larger than the diameter of the first through hole 3331 of the i-shaped coupling member 333, and the collet 3154 is screw-coupled with the third rod portion 3153. When the driving rod 315 is connected to the pressing plate portion 33, the retaining head 3154 may be unscrewed from the end of the third rod portion 3153, the end of the third rod portion 3153 may be inserted through the first through hole 3331 of the i-shaped connecting member 333, and then the retaining head 3154 may be screwed to the end of the third rod portion 3153, thereby fixedly connecting the pressing plate portion 33 and the driving rod 315.

In this embodiment, as shown in fig. 10, the press bending apparatus further includes a stopping mechanism 50. The stopping mechanism 50 is slidably connected to the side plate 20, and the stopping mechanism 50 is used for stopping the pressing plate portion 33 at a predetermined position, thereby controlling the position of the pressing block 32. Because the pressing block 32 has different bending angles when bending the product to be bent, the bending angle of the product to be bent can be indirectly controlled by controlling the position of the stopping mechanism 50.

Further, in this embodiment, the side plate 20 may have a kidney-shaped hole, and the stopping mechanism 50 may be slidably connected to the side plate 20 by a stud passing through the kidney-shaped hole. Alternatively, as shown in FIG. 10, the stop mechanism 50 may be a stop block.

Alternatively, as shown in fig. 10, one end of the guide rod 60 may be fixed to the side plate by a guide rod fixing block 61, and the other end of the guide rod 60 is fixedly connected to the base 10.

In this embodiment, as shown in fig. 11, the press bending apparatus further includes a reinforcing plate 70, the reinforcing plate 70 is located on a side of the side plate 20 where the pressing mechanism is not located, and the reinforcing plate 70 is fixedly connected to the side plate 20 and the base 10 respectively, so as to increase the pressure bearing capacity of the side plate 20. Alternatively, as shown in fig. 11, a plurality of feet 80 may be further provided at the bottom of the base 10, and the feet 80 may be used to support the base 10.

Next, in this embodiment, a method of using the press-type bending apparatus will be described by taking the press-type bending apparatus shown in fig. 1 as an example.

Firstly, a product to be bent is placed on the placing groove, a part to be bent of the product to be bent is located at the abutting positions of the two rollers 421, then a proper pressing block 32 is selected according to the size of the product to be bent and the bending requirement of the product to be bent, the pressing block 32 is installed on the pressing plate portion 33, and then the position of the stopping mechanism 50 is adjusted according to the requirement of the bending angle of the product to be bent, so that the pressing plate portion 33 can be stopped when reaching the preset position.

Next, the control handle 313 is moved to drive the pressing block 32 to move towards the direction close to the bearing part 41, in the process, the arc surface of the pressing block 32 contacts with the part to be bent of the product to be bent and presses the part to be bent between the two rollers 421, the two rollers 421 rotate and separate with the rotating shaft 422 as a rotating center, when the pressing plate part 33 moves to a preset position, the control handle 313 stops moving, at this time, the product to be bent is bent, and the distance between the two rollers 421 is controlled to be greater than or equal to the length of the limiting block 442 of the limiting part 44 in the first direction, so that the third part 4421 of the limiting block 442 is located between the two rollers 421, so as to be capable of limiting the positions of the two rollers 421, and prevent the two rollers 421 from pressing the product to be bent under the action of the return spring 43.

Subsequently, the handle 313 may be controlled to move the pressing block 32 away from the bearing portion 41, so that the pressing block 32 is away from the bent product, and finally the bent product is taken out. Before the next product to be bent is bent, the pressing block 441 can be pressed in the second direction, the spring 443 is compressed, the pressing block 441 moves in the second direction, and drives the fourth portion 4422 to move in the second direction, and at this time, the third portion 4421 located between the two roller portions 42 moves in the second direction. When the third portion 4421 is removed from between the two roller portions 42, the two rollers 421 approach each other and finally abut under the action of the return spring 43, ready for bending of the next product to be bent.
