DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a material blocking device for a bending machine, comprising a mounting beam 19, wherein strip seats 1 are vertically mounted at both ends of one side of the mounting beam 19, and the other ends of the strip seats 1 are connected by a supporting beam 2, such as Figure 2 As shown, the mounting beam 19, the two strip seats 1 and the support beam 2 form a quadrilateral frame structure, and mounting frames 17 are provided at both ends of the bottom of the strip seat 1. Figure 3 As shown, ①, the material blocking device can be installed inside the bending machine through the mounting frame 17; Figure 4 As shown, ②, or the mounting frame 17 is used as a supporting leg, the mounting frame 17 is supported on the ground, and the material blocking device is located on the back side of the bending machine.

[0023] like Figure 2 As shown, a plurality of strip plates 11 arranged in parallel with the strip seat 1 are provided on the top of the mounting beam 19, the number of the strip plates 11 is at least three, one end of the strip plate 11 away from the mounting beam 19 extends to the outside of the end of the strip seat 1, that is, the strip plate 11 extends to the outside of the quadrilateral frame structure, and the strip plate 11 is placed on the top of the support beam 2, so that the strip plate 11 can be connected to the mounting beam while being supported by the support beam 2, so that the strip plate is supported by two points at the same time, so that the strip plate 11 can be smoothly extended to the upper and lower templates in the inlet of the bending machine;

[0024] The specific operation process of the strip board is that the strip board mainly supports the board, such as Figure 3 and Figure 4 As shown, one end of the strip plate 11 away from the mounting beam 19 is placed at the bending opening, and the plate to be bent (such as Figure 3 and Figure 4The plate is placed inside the bending mouth of the bending machine, and the plate extending into the bending machine can be directly placed on the strip plate 11 for support.

[0025] like Figure 1 As shown, a connecting beam 8 parallel to the mounting beam 19 is provided above the strip plate 11, and the connecting beam 8 does not contact the strip plate 11. A linear drive module connected to the end of the connecting beam 8 and driving the connecting beam 8 to reciprocate along the strip plate 11 is provided on each strip seat 1. The two linear drive modules move synchronously. When the linear drive modules move, they can drive the connecting beam 8 to reciprocate, so that the connecting beam 8 is close to the bending opening or away from the bending opening.

[0026] The top of the connecting beam 8 is connected to a plurality of support arms 13 extending toward the supporting beam 2. The support arms 13 are parallel to the strip plates 11 and their ends are vertically connected to the sides of the strip baffles 15. The strip baffles 15 are parallel to the mounting beams 19. The strip baffles 15 and the strip plates 11 are fitted with a gap. Here, the strip plates 11 can move with the movement of the connecting beam 8.

[0027] The specific operation process of the strip baffle 15 is as follows: the plate to be bent (such as Figure 3 and Figure 4 After the plate (indicated by the middle arrow A) is placed inside the opening of the bending machine, first place the plate on the strip plate 11 and position it horizontally, then push the strip plate 11 and let one side of it abut against the side of the strip baffle 15, so that the strip plate 11 is in contact with the strip baffle 15, and the bending part of the plate is just inside the bending mouth, and the bending machine can be controlled to bend at this time.

[0028] It should be noted that after the plate is placed inside the bending machine, the plate is placed on the strip plate 11 for horizontal positioning, and then the side of the plate contacts the strip baffle 15, so that the plate can be positioned deep inside the bending machine.

[0029] Furthermore, the strip plate 11 is adjustable, that is, a first guide rail 18 is installed on the top of the mounting beam 19, and at least three first sliders 12 matching therewith are slidably arranged on the first guide rail 18, and the top of the strip plate 11 is located on the top of the first slider 12 and the two are fastened by bolts;

[0030] Moreover, if Figure 1 and Figure 2As shown, a rectangular groove 9 matching the width of the strip plate 11 is provided on the top of the first slider 12, and one end of the strip plate 11 is placed in the rectangular groove 9 to make the two match more stably, and a strip opening 10 is opened on the end of the strip plate 11, and a bolt is fastened in the strip opening 10. When the bolt is loosened, the strip plate can slide in the rectangular groove to adjust the gap between the strip plate and the bending opening to prevent the gap between the strip plate and the bending opening from being too large.

[0031] Furthermore, the specific structure of the linear drive module includes second guide rails 6 respectively installed on the top of the bar seat 1, and the second guide rails 6 are each provided with a second slider 5 matching therewith, such as Figure 1 As shown, both ends of the connecting beam 8 are fastened to the second slider 5 by bolts respectively;

[0032] The linear drive module also includes two ball screws 3, such as Figure 2 As shown, two ball screws 3 are respectively placed on the side of the strip seat 1, and each ball screw 3 is provided with a ball nut 14, and each ball nut 14 is connected to the second slider 5 through a connecting frame 4;

[0033] One end of the ball screw 3 is rotatably connected to the end of the mounting beam 19, and a driving motor 7 connected to the ball screw is installed outside the two ends of the mounting beam 19, and the driving motor 7 is preferably a servo motor. The two servo motors move synchronously, and the end of the ball screw 3 away from the mounting beam is rotatably connected to the bearing seat 16, and the bearing seat 16 is connected to the end of the strip seat 1. Therefore, when the driving motor rotates, it can drive the ball screw 3 to rotate, and the ball screw 3 drives the connecting beam 8 to move forward or away from the bending mouth, thereby changing the distance between the strip baffle 15 and the bending mouth.

[0034] Based on the above embodiment, further optimization can be performed, because in the actual production process, the working process of the bending machine is continuous, that is, a plate needs to be bent multiple times to be formed, so the depth of the plate extending into the bending machine may be different, so the drive motor can be connected to the control system of the bending machine to accurately control the drive motor. After the first bending process is completed, the drive motor will automatically drive the strip baffle 15 to move to the next bending position, and the process can be repeated, which is convenient for operators to operate and facilitates continuous bending work.
