[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1 , Figure 2 and Figure 4 As shown, this utility model is a stable conveying sheet metal bending machine, specifically capable of limiting the placement of metal sheets 7 of different sizes, including a fixed base 1; a pushing component 2 is provided on the inner side of the left end of the fixed base 1 for pushing the metal sheet 7 to the right, and a first side baffle 3 and a second side baffle 4 are respectively provided on the upper left side surface of the fixed base 1.

[0033] In this embodiment, preferably, the cross-sectional shape of the first side baffle 3 and the second side baffle 4 is "L" shaped, and the lower outer side of the first side baffle 3 and the second side baffle 4 are both fixedly installed with connecting ear blocks 5.

[0034] The inner side of the connecting ear block 5 is provided with a second adjusting bolt 6 that is threadedly connected to the fixed base 1. The lower outer side of the second adjusting bolt 6 is provided with holes and slots that are evenly distributed in the fixed base 1.

[0035] In this embodiment, preferably, a limiting groove is provided on the lower right side of the second side baffle 4, a movable baffle 401 is provided inside the limiting groove, and a first adjusting bolt 402 is provided at the connection between the movable baffle 401 and the second side baffle 4.

[0036] The movable baffle 401 forms a snap-fit ​​sliding structure within the second side baffle 4, and both the movable baffle 401 and the second side baffle 4 are connected to the first adjusting bolt 402 by means of threads.

[0037] In summary, firstly, the first side baffle 3 and the second side baffle 4 are stably aligned with the slots on the upper surface of the fixed base 1 by the connecting lugs 5 fixedly installed at the lower end. Then, the second adjusting bolt 6 is threaded through the slots on the inner side of the fixed base 1 and the connecting lugs 5 to secure the connection. Since the cross-sections of the first side baffle 3 and the second side baffle 4 are both "L" shaped, the metal plates 7 can be stacked on the inner side of the first side baffle 3 and the second side baffle 4 in sequence. This can accurately and stably lock and limit the four corners of the metal plates 7, avoiding shaking or displacement that could cause deviation. Furthermore, the slots are evenly distributed on the upper surface of the fixed base 1, allowing the installation positions of the first side baffle 3 and the second side baffle 4 to be adjusted at any time according to the actual size of the metal plates 7, so as to accommodate metal plates 7 of different sizes.

[0038] Furthermore, the first side baffle 3 is designed as a single unit from top to bottom, while the lower right side of the second side baffle 4 has a limiting groove to facilitate the pushing and conveying of the metal sheet 7 from the lower end of the second side baffle 4 to the right. A movable baffle 401 is also provided at the lower end of the second side baffle 4, and the movable baffle 401 is connected to the second side baffle 4 by a threaded connection via a first adjusting bolt 402. With this design, when the thickness of the metal sheet 7 is uncertain, the thickness can be measured before operation, and then the movable baffle 401 can be manually adjusted upwards. 01 Slides within the limiting groove opened in the second side baffle 4, and then uses the first adjusting bolt 402 for limiting and fixing. This can limit the metal plates 7 of different thicknesses and sizes, and prevent some metal plates 7 from being too thin when they leave the factory. This would cause the movable baffle 401 to be too far from the upper surface of the fixed base 1, resulting in the metal plate 7 being disengaged from the limiting engagement state of the first side baffle 3 and the second side baffle 4, causing displacement during subsequent transportation. By using the first side baffle 3 and the second side baffle 4 in cooperation, the metal plates 7 of different sizes can be limited and placed to the greatest extent.

[0039] Example 2

[0040] Please see Figure 1 and Figure 3 As shown, this utility model is a stable conveying sheet metal bending machine, specifically capable of stably conveying metal sheet 7. The pushing component 2 is composed of a reciprocating screw 201, a movable connecting block 202, a return spring 203, and a movable wedge block 204.

[0041] The reciprocating lead screw 201 is located inside the left side of the fixed base 1, and a servo motor is installed at its left end. A movable connecting block 202 is provided on the outside of the reciprocating lead screw 201. A return spring 203 is provided on the upper inside of the movable connecting block 202. A movable wedge block 204 connected to the movable connecting block 202 is provided above the return spring 203.

[0042] In this embodiment, preferably, the upper surface of the movable wedge 204 is inclined, and the movable wedge 204 forms an elastic telescopic structure within the movable connecting block 202 through the return spring 203.

[0043] The movable connecting block 202 is connected to the reciprocating lead screw 201 by a thread, and the movable connecting block 202 forms a snap-fit ​​sliding structure on the inner side of the fixed base 1.

[0044] The movable connecting block 202 is arranged symmetrically about the center line of the fixed base 1.

[0045] In summary, after the metal plates 7 are stacked completely, the servo motor is turned to rotate the reciprocating screw 201, causing the movable connecting block 202, which is threadedly connected to the reciprocating screw 201, to slide laterally within the fixed base 1. Since the upper end of the movable wedge 204 is tilted to the left, when the right end of the movable wedge 204 contacts the metal plate 7, it can push and convey the metal plate 7 to the right, allowing it to reach the surface directly above the bending groove 10 for the next bending operation. Then, the servo motor is turned to rotate the reciprocating screw 201 again, causing the movable connecting block 202 to return to its initial starting position under the action of the reciprocating screw 201. Simultaneously, the movable wedge 204 contacts the metal plate 7 again. The movable wedge 204, through the return spring 203, forms an elastic telescopic movement within the movable connecting block 202. Under the pressure of the first side baffle 3, the metal plate 7 generates resistance, which slides and presses the movable wedge 204. Under the action of the return spring 203, the movable wedge 204 extends and retracts downward, sliding over the lower surface of the metal plate 7, thereby achieving the effect of reciprocating pushing and resetting. Furthermore, the movable wedge 204 is symmetrically arranged about the center line of the fixed base 1. The two sets of arrangements can increase the stability of pushing and conveying the metal plate 7, and avoid the deviation caused by uneven pushing force after the metal plate 7 leaves the contact with the first side baffle 3 and the second side baffle 4 due to the single-rail movement.

[0046] Example 3

[0047] Reference Figure 1 and Figure 2The image shows the second embodiment of this utility model. Specifically, a bending groove 10 is provided on the inner side of the right end of the fixed base 1, an auxiliary guide wheel 11 is provided on the inner side of the bending groove 10, and a stamping head 15 is provided above the bending groove 10.

[0048] In this embodiment, preferably, the auxiliary guide wheels 11 are symmetrically and equidistantly arranged on the inner side of the bending groove 10, and the longitudinal cross-section of the bending groove 10 is arranged in a "V" shape.

[0049] In this embodiment, preferably, a fixed horizontal plate 13 is provided above the punching head 15, and an irregular baffle 14 is fixedly installed on the right end of the fixed horizontal plate 13.

[0050] In this embodiment, preferably, the longitudinal section of the irregular baffle 14 is a "7" shaped structure, and the lowest end of the irregular baffle 14 is lower than the lowest end of the stamping head 15, which is used to pre-contact the fixed base 1 to shield the metal plate 7.

[0051] In summary, the outer frame 8 is fixed to the fixed base 1 by threaded connection through the third adjusting bolt 9. When the metal plate 7 is pushed and conveyed to the upper surface of the bending groove 10, the hydraulic telescopic rod 12 installed on the upper inner side of the outer frame 8 is opened. When the fixed horizontal plate 13 is driven to descend, the punch head 15 can be used to punch the metal plate 7, so that the metal plate 7 moves into the bending groove 10 to achieve the bending effect. Here, the longitudinal section of the bending groove 10 is set to a "V" shaped structure, which can bend the metal plate 7 to the maximum extent and avoid the metal plate 7 from breaking at the bending point. Under the action of the equidistant and inclined auxiliary guide wheels 11, the auxiliary movement effect of the metal plate 7 is increased, and the smoothness of bending is improved.

[0052] Furthermore, a fourth adjusting bolt 16 is provided at the connection between the fixed horizontal plate 13 and the punching head 15, which facilitates the disassembly and replacement of the punching head 15 later. In addition, the bottom end of the irregular baffle 14 is lower than the bottom end of the punching head 15. When the movable wedge 204 pushes the metal sheet 7 to the right to the upper surface of the bending groove 10, the fixed horizontal plate 13 is slightly lowered, so that the irregular baffle 14 can contact the upper surface of the fixed base 1 first and abut against the rightmost end of the metal sheet 7. With the mutual shielding of the movable wedge 204 and the irregular baffle 14, the metal sheet 7 can be prevented from shaking during punching and bending, thereby improving the working effect.
