Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] See appendix Figure 1 To be continued Figure 4 As shown, this embodiment provides a bidirectional CNC bending machine 10, including a frame 100, an automatic pressing device 500, an automatic feeding device 600, a starting point positioning device 800, and a dual-axis automatic bending device 700. A table 200 is mounted on the upper surface of the frame 100. Two opposite ends of the table 200 are the input end 300 and the output end 400 of the sheet metal (metal sheet or profile) to be processed. The automatic pressing device 500, the automatic feeding device 600, and the dual-axis automatic bending device 700 are arranged sequentially on the table 200 along the conveying direction of the sheet metal. Each of the automatic pressing device 500, the automatic feeding device 600, and the dual-axis automatic bending device 700 has a reserved conveying channel for the sheet metal to enter. The automatic pressing device 500 is located on the table 200 near the input end 300; the dual-axis automatic bending device 700 is located on the table 200 near the output end 400. It should be noted that in this embodiment, the dual-axis automatic bending device 700 can adopt the bending structure in the prior art, and its specific structure will not be described here.

[0029] See attached document Figure 2 and attached Figure 6 As shown, the automatic pressing device 500 is arranged on the table 200 near the input end 300. The automatic pressing device 500 is used to press the material to be processed before bending, that is, to press the material to be processed.

[0030] In this embodiment, the automatic pressing device 500 includes a feed end fixing seat 504 and a feed end cylinder fixing seat 501. The feed end fixing seat 504 and the feed end cylinder fixing seat 501 are arranged opposite to each other, that is, the feed end fixing seat 504 and the feed end cylinder fixing seat 501 are fixedly installed on both sides of the conveying channel. A feed end fixing pressure plate 505 is installed on the inner side of the feed end fixing seat 504, a feed end side pressure cylinder 502 is installed on the feed end cylinder fixing seat 501, and a feed end movable pressure plate 503 is installed on the feed end side pressure cylinder 502.

[0031] When it is necessary to press the material to be processed, the feed end side pressure cylinder 502 extends outward and pushes the feed end movable pressure plate 503 to move closer to the feed end fixed pressure plate 505 so as to press the material to be processed between the feed end fixed pressure plate 505 and the feed end movable pressure plate 503.

[0032] See attached document Figure 2 Appendix Figure 4 and appendix Figure 5 As shown, the automatic feeding device 600 is used to convey the sheet material to be processed forward. In this embodiment, the automatic feeding device 600 includes a fixed feeding active mold assembly 602 and a side pressure cylinder assembly 601. The fixed feeding active mold assembly 602 and the side pressure cylinder assembly 601 are arranged opposite to each other on both sides of the conveying channel. The fixed feeding active mold assembly 602 and the side pressure cylinder assembly 601 are fixedly installed on the table 200. The side pressure cylinder assembly 601 can move and approach one side relative to the fixed feeding active mold assembly 602.

[0033] See attached document Figure 4 and attached Figure 5As shown, specifically, the fixed feeding active mold assembly 602 includes a servo motor 6023, a first feeding active mold 6021, and a second feeding active mold 6022. The upper ends of the first feeding active mold 6021 and the second feeding active mold 6022 are respectively fixedly installed with main drive shaft synchronous pulleys 6025. The first feeding active mold 6021 and the second feeding active mold 6022 are respectively rotatably installed on the table 200. The conveying end of the servo motor 6023 is connected to the main drive shaft synchronous pulley 6025 located on the first feeding active mold 6021 through a synchronous belt 6024. The main drive shaft synchronous pulleys 6025 located on the first feeding active mold 6021 and the second feeding active mold 6022 are connected by a series synchronous belt 6026. In this way, the power output from the servo motor 6023 output terminal 400 is transmitted to the first feeding active mold 6021 through the synchronous belt 6024, causing the first feeding active mold 6021 to rotate. At the same time, the rotating first feeding active mold 6021 drives the second feeding active mold 6022 to rotate through the series synchronous belt 6026. The rotating first feeding active mold 6021 and the rotating second feeding active mold 6022 can drive the material to be processed to move forward.

[0034] Continue to refer to the appendix Figure 4 and attached Figure 5 As shown, the side-pressure cylinder assembly 601 includes a side-pressure cylinder 6011, a base, a feeding side-pressure cylinder head fixing plate 6012, a first active mold 6013, and a second active mold 6014. The base is fixedly installed on the table 200 on the other side opposite to the fixed feeding active mold assembly 602. The side-pressure cylinder 6011 is fixedly installed on the base and is fixedly connected to the feeding side-pressure cylinder head fixing plate 6012. The first active mold 6013 and the second active mold 6014 are respectively rotatably installed on the feeding side-pressure cylinder head fixing plate 6012. The first active mold 6013 and the first feeding active mold 6021 are arranged opposite to each other, and the second active mold 6014 and the second feeding active mold 6022 are arranged opposite to each other.

[0035] During use, the side pressure cylinder 6011 can extend outward, driving the feeding side pressure cylinder head fixing plate 6012 to move towards the side of the fixed feeding active mold assembly 602, so that the first active mold 6013 and the first feeding active mold 6021 cooperate, and the second active mold 6014 and the second feeding active mold 6022 cooperate. In this way, the plate to be processed can be conveyed forward along the space between the first active mold 6013 and the first feeding active mold 6021 and between the second active mold 6014 and the second feeding active mold 6022.

[0036] In the above structure, when the sheet metal is conveyed and bent along the conveying channel, the side pressure cylinder assembly 601 moves closer to the fixed feeding active mold assembly 602. The two work together to realize the automatic conveying of the sheet metal. When the side pressure cylinder assembly 601 moves in the opposite direction and resets, the conveying channel is formed again between the side pressure cylinder assembly 601 and the fixed feeding active mold assembly 602, and the metal sheet metal can continue to be conveyed forward. The whole structure is compact and ingeniously designed, which can reduce the manufacturing cost of the entire equipment.

[0037] See attached document Figure 3 and attached Figure 5 As shown, in this embodiment, the starting point positioning device 800 is used to position the starting point of the material to be processed. The starting point positioning device 800 is disposed on one side of the fixed feeding active mold assembly 602. In this embodiment, the starting point positioning device 800 includes a mounting base, a positioning cylinder 801, and a positioning baffle 802. The mounting base is fixedly installed on the outer side of the table 200 near the fixed feeding active mold assembly 602. The positioning cylinder 801 is fixedly installed on the mounting base, and the positioning baffle 802 is fixedly installed on the positioning cylinder 801.

[0038] See attached document Figure 1 and attached Figure 2 As shown, to facilitate the installation of the servo motor 6023 in the automatic feeding device 600, a feeding support plate 110 is provided above the automatic feeding device 600, and the servo motor 6023 is fixedly mounted on the feeding support plate 110. In addition, to provide some protection for the automatic feeding device 600, a synchronous belt cover 900 is installed on the feeding support plate 110, and the servo motor 6023, the synchronous belt, and the series synchronous belt 6026 are located in the inner cavity of the synchronous belt cover.
