[0041] Before using the equipment, manually place the sheet metal workpiece in the feeding mechanism 2. The sheet metal workpiece is between the first fixed frame 10 and the second fixed frame 11, which is the feeding station. Then turn on the motor in the motor box 8, and the motor drives the connecting cylinder 9 and the feeding mechanism 2 to move until the sheet metal workpiece is at the bottom of the tool holder 13, which is the cutting station. Adjust the feeding mechanism 2 and the receiving mechanism 3, adjust the position of the sheet metal workpiece, and then turn on the power system in the tool holder 13 to complete the cutting work. During the cutting work, manually complete the loading of the next sheet metal workpiece.

A conical rod is fixedly connected to the outside of the second telescopic rod 2036. The central plate 2033 is fixedly connected inside the disc 202.

[0046] The placing component 203 further includes a spring 2037. A baffle 2038 is fixedly connected to the outside of the spring 2037. A hinge 2039 is installed on the outside of the baffle 2038. The hinge 2039 is installed inside the disc 202. Both the spring 2037 and the baffle 2038 are provided with two, and are symmetrically arranged. The spring 2037 is fixedly connected to the outside of the central plate 2033.

[0047] When it is necessary to adjust the position of the sheet metal workpiece, turn on the second telescopic rod 2036. The second telescopic rod 2036 drives the conical rod to move towards the sliding frame 2035. The conical rod contacts and drives the two baffles 2038 to rotate outside the two hinges 2039. At this time, the spring 2037 deforms. The conical rod gradually contacts the sliding frame 2035 and drives the sliding frame 2035 to move in the sliding groove 2034, thereby driving the fixing component 204 to move. The fixing component 204 drives the sheet metal component to move to adjust the position of the sheet metal component.

[0048] The fixing component 204 includes a groove 2041. A first telescopic bent rod 2042 is fixedly connected inside the groove 2041. The bottom of the first telescopic bent rod 2042 is fixedly connected with an arc-shaped plate 2043. The bottom of the arc-shaped plate 2043 is fixedly connected with a pressing rod 2044. A plurality of pressing rods 2044 are provided. The bottom of the pressing rod 2044 is fixedly connected with a rubber strip. An expansion column 2045 is fixedly connected to the outside of the sliding frame 2035. The expansion column 2045 is fixedly connected inside the sliding groove 2034. The groove 2041 is opened inside the sliding frame 2035.

[0049] A through hole is formed inside the sliding carriage 2035, and a conical cylinder 2046 is fixedly connected to the outside of the sliding carriage 2035. The conical cylinder 2046 is located at the through hole. A plurality of cushion blocks 2047 are fixedly connected to the outside of the sliding carriage 2035.

[0050] The first telescopic bent rod 2042 is opened to the maximum stroke. The first telescopic bent rod 2042 drives the arc-shaped plate 2043 and the pressure rod 2044 to move upward, reserving a working space for placing the sheet metal workpiece. Subsequently, the sheet metal workpiece is manually placed in the placement groove 2031, and the sheet metal workpiece contacts the plurality of cushion blocks 2047. The first telescopic bent rod 2042 is adjusted to the corresponding stroke. The first telescopic bent rod 2042 drives the arc-shaped plate 2043 and the pressure rod 2044 to move towards the sheet metal workpiece until the rubber strip at the bottom of the pressure rod 2044 presses on the sheet metal workpiece to fix the position of the sheet metal workpiece.

[0051] As the conical rod gradually contacts the sliding carriage 2035, the conical rod gradually snaps into the conical cylinder 2046 and drives the sliding carriage 2035 to move in the sliding groove 2034, thereby adjusting the telescopic column 2045 to different strokes. During the movement of the sliding carriage 2035, the first telescopic bent rod 2042, the arc-shaped plate 2043, the pressure rod 2044, the cushion blocks 2047, and the sheet metal workpiece start to move, thereby pushing the sheet metal workpiece to the cutting station, the bending station, or the discharging station.

[0052] When it is necessary to complete the discharging work, the first telescopic bent rod 2042 is adjusted to the initial state. The pressure rod 2044 and the rubber strip are separated from the sheet metal workpiece. Driven by the sliding carriage 2035, the sheet metal workpiece gradually enters the transportation channel 12 to complete the discharging work.

[0053] A fifth telescopic rod 304 is fixedly connected inside the fixed frame 303. A clamping plate 305 is fixedly connected to the outside of the fifth telescopic rod 304. A support plate 306 is fixedly connected to the outside of the clamping plate 305. One end of the support plate 306 away from the clamping plate 305 is set as an inclined edge. A stretching plate 307 is fixedly connected to the outside of the clamping plate 305. One end of the stretching plate 307 away from the clamping plate 305 is fixedly connected inside the fixed frame 303. A plurality of stretching plates 307 are provided.

[0054] Before cutting, bending or unloading, the third telescopic rod 301 is opened, and the third telescopic rod 301 drives the fourth telescopic rod 302 and the fixed frame 303 to move toward the sheet metal workpiece. The fourth telescopic rod 302 is opened, and the fourth telescopic rod 302 drives the fixed frame 303 to move upward until the fixed frame 303 is flush with the placement slot 2031. As the tapered rod drives the sliding frame 2035 and the sheet metal workpiece to move, the sheet metal workpiece is gradually placed on the support plate 306. According to the cutting length or bending position, the fifth telescopic rod 304 is adjusted to the corresponding stroke, and the fifth telescopic rod 304 drives the support plate 306 to move outward, extending the movement space of the sheet metal workpiece.

[0055] Working principle: Before using the equipment, manually place the sheet metal workpiece in the feeding mechanism 2. The sheet metal workpiece is between the first fixed frame 10 and the second fixed frame 11, which is the feeding station. Open the first telescopic bending rod 2042 to the maximum stroke, and the first telescopic bending rod 2042 drives the arc plate 2043 and the pressure rod 2044 to move upward to reserve a working space for placing the sheet metal workpiece. Then manually place the sheet metal workpiece in the placement groove 2031, and the sheet metal workpiece contacts with multiple pads 2047. Adjust the first telescopic bending rod 2042 to the corresponding stroke, and the first telescopic bending rod 2042 drives the arc plate 2043 and the pressure rod 2044 to move in the direction of the sheet metal workpiece until the rubber strip at the bottom of the pressure rod 2044 presses on the sheet metal workpiece to fix the position of the sheet metal workpiece.

[0056] Then, the motor in the motor box 8 is turned on, and the motor drives the connecting tube 9 and the feeding mechanism 2 to move until the sheet metal workpiece is at the bottom of the tool holder 13. For the cutting station, the feeding mechanism 2 and the receiving mechanism 3 are adjusted to adjust the position of the sheet metal workpiece. When the position of the sheet metal workpiece needs to be adjusted, the second telescopic rod 2036 is turned on, and the second telescopic rod 2036 drives the tapered rod to move in the direction of the sliding frame 2035. The tapered rod contacts and drives the two baffles 2038 to rotate outside the two hinges 2039, and the spring 2037 is deformed at this time. The tapered rod gradually contacts the sliding frame 2035, and drives the sliding frame 2035 to move in the slide groove 2034, thereby driving the fixed component 204 to move, and the fixed component 204 drives the sheet metal component to move to adjust the position of the sheet metal component.

[0057] As the conical rod gradually contacts the sliding frame 2035, the conical rod gradually gets stuck in the conical cylinder 2046, and drives the sliding frame 2035 to move in the slide slot 2034, thereby adjusting the telescopic column 2045 to different strokes. During the movement of the sliding frame 2035, the first telescopic bending rod 2042, the arc plate 2043, the pressure rod 2044, the cushion block 2047 and the sheet metal workpiece begin to move, thereby pushing the sheet metal workpiece to the cutting station, the bending station or the unloading station. Before the cutting work, the bending work or the unloading work, the third telescopic rod 301 is opened, and the third telescopic rod 301 drives the fourth telescopic rod 302 and the fixed frame 303 to move in the direction of the sheet metal workpiece, and the fourth telescopic rod 302 is opened, and the fourth telescopic rod 302 drives the fixed frame 303 to move upward until the fixed frame 303 is level with the placement slot 2031. As the tapered rod drives the sliding frame 2035 and the sheet metal workpiece to move, the sheet metal workpiece is gradually placed on the support plate 306. According to the cutting length or bending position, the fifth telescopic rod 304 is adjusted to the corresponding stroke. The fifth telescopic rod 304 drives the support plate 306 to move outward, thereby extending the movement space of the sheet metal workpiece.

[0058] At this time, the power system in the tool holder 13 is turned on to complete the cutting work. During the cutting work, the loading work of the next sheet metal workpiece is completed manually.

[0059] Adjust the motor again until the sheet metal workpiece is at the bending machine 5, adjust the feeding mechanism 2 and the receiving mechanism 3, adjust the position of the sheet metal workpiece, and then start the bending machine 5 to complete the bending of the sheet metal workpiece. Finally, adjust the motor until the sheet metal workpiece is at the first fixed frame 10, adjust the feeding mechanism 2, and complete the unloading of the sheet metal workpiece.

[0060] When the unloading work needs to be completed, the first telescopic bending rod 2042 is adjusted to the initial state, the pressure rod 2044 and the rubber strip are separated from the sheet metal workpiece, and the sheet metal workpiece gradually enters the transport channel 12 under the drive of the sliding frame 2035 to complete the unloading work.

[0061] After the work is completed, the first telescopic rod 205 is turned on to the reciprocating motion mode, the first telescopic rod 205 drives the lifting ring 206 to move up and down, and the lifting ring 206 repeatedly hits the fixed outer ring 207 to promote the falling of the broken materials outside the receiving mechanism 3.
