[0035] As shown in the accompanying Figure 1 ~ attached Figure 9 It also comprises an electric heating sleeve 5 arranged on one side of the base 1.

[0036] Specific electric heating sleeve 5 uses power frequency alternating current, and the electric heating sleeve 5 heats the angle steel, then the angle steel is placed on the bottom die plate 3, and then the angle steel is pressed and bent by the bottom die plate 3 and the pressing die plate 4, and finally the whole bending process is completed.

[0037] Specifically, the electric heating sleeve 5 is a right-angled electric heating sleeve 5, and the angle steel can pass between the electric heating sleeves 5 before being pressed and bent.

[0038] As shown in the accompanying Figure 1 ~ attached Figure 9 As shown, it also includes a conveying frame 6 and a pushing frame 7, the conveying frame 6 is arranged on one side of the electric heating sleeve 5, one side of the conveying frame 6 is provided with a guide rail 8, one side of the guide rail 8 is provided with a rack 9, the rack 9 is in parallel with the guide rail 8, the pushing frame 7 is in sliding fit with the guide rail 8, the pushing frame 7 is provided with a pushing motor 10, the shaft of the pushing motor 10 is in fit with the rack 9 through a gear.

[0039] Specifically, the conveying frame 6 is used to guide and clamp the angle steel, and the angle steel can move on the conveying frame 6 when subjected to external force. When the angle steel is subjected to external force, it can enter the electric heating sleeve 5 for heating, and after heating is completed, it can also be moved out of the conveying frame 6 under the action of external force. In this bending device, a guide rail 8 is arranged on one side of the conveying frame 6, a rack 9 parallel to the guide rail 8 is arranged on one side of the guide rail 8, a pushing frame 7 is slidingly installed on the guide rail 8, a pushing motor 10 is arranged on the pushing frame 7, the shaft of the pushing motor 10 is in meshing fit with the rack 9 through a gear. When the pushing motor 10 operates, the pushing frame 7 slides along the guide rail 8, and the pushing frame 7 can push the angle steel on the conveying frame 6 to move on the conveying frame 6. The angle steel can slide into or out of the electric heating sleeve 5 when sliding on the sliding frame.

[0040] Specifically, the conveying frame includes a bottom plate 601 and a plurality of supporting rollers 602, the bottom plate 601 is an isosceles trapezoidal bottom plate 601, both ends of the bottom plate 601 are rotatably installed with supporting rollers 602, the supporting rollers 602 are in a rotatable state relative to the bottom plate 601, the supporting rollers 602 are used to contact the outer wall of the angle steel, and the rotation of the supporting rollers 602 can make the angle steel slide relative to the bottom plate 601.

[0041] Specifically, in this device, in order to stably push the angle steel to move on the conveying frame 6, two tension hooks 11 and a clamping cylinder 12 are further arranged on the pushing frame, both ends of the two tension hooks 11 are rotatably installed on the pushing frame, and the other ends of the two tension hooks 11 are in fit with the clamping cylinder 12. When the cylinder rod of the clamping cylinder 12 shrinks, the two tension hooks 11 approach each other, and the two tension hooks 11 can clamp the angle steel when they approach each other. When the cylinder rod of the clamping cylinder 12 is elongated, the two tension hooks 11 are stretched, and the two tension hooks 11 no longer clamp the angle steel.

[0042] When the two tension hooks 11 clamp the angle steel, the pushing frame can stably move back and forth on the conveying frame 6 with the angle steel.

[0043] In the specific device, a plurality of lifting cylinders 13 are installed on a frame 14 installed on one side of the base 1, and the guide rail 8 and the rack 9 are also installed on the frame 14.

When the cylinder rods of the lifting cylinders 13 are extended, all the conveying frames 6 are arranged together to form a complete conveying belt, and the complete conveying belt can continuously and stably convey the angle steel. When the cylinder rods of the lifting cylinders 13 are retracted, all the conveying frames 6 no longer form a complete conveying belt, and an avoiding gap is formed on the conveying belt. The avoiding gap facilitates the clamping jaw on the mechanical arm 15 to clamp the angle steel, and ensures that the clamping jaw has good clamping efficiency on the angle steel.

[0044] As shown in the accompanying drawings, the device also comprises a mechanical arm 15 and a clamping jaw. The clamping jaw is arranged on the mechanical arm 15, and the mechanical arm 15 is arranged on one side of the base 1. Figure 1 Figure 9 The clamping jaw is installed on the mechanical arm 15, and the clamping jaw is used to clamp the angle steel.

[0045] The clamping jaw is installed on the mechanical arm 15, and the clamping jaw is used to clamp the angle steel. The mechanical arm 15 is used to transport the angle steel after the angle steel is clamped.

[0046] ​The specific clamping claws include a clamping base 1601, an electromagnetic adsorption claw 1602 and a suspension clamp 1603. The electromagnetic adsorption claw 1602 is installed on the clamping base 1601. The electromagnetic adsorption claw 1602 directly uses magnetic attraction to adsorb and clamp the angle steel. Before the angle steel is heated by the electric heating sleeve 5, the angle steel can be clamped by the electromagnetic adsorption claw 1602. Specifically, a slide rail 1604 is also installed in the clamp seat 1601, and there are two suspension clamps 1603. The two suspension clamps 1603 are respectively slidably installed on the slide rails 1604, and an adjusting screw 1605 is rotatably installed in the clamp seat 1601.

[0050] The specific temporary storage table 18 is also located on one side of the conveyor frame 6. The functions of the rotating seat 19, the supporting arm 20 and the electromagnetic magnet are to adsorb and reverse the angle steel, and the function of the temporary storage table 18 is to place the reversed angle steel. The specific whole process is as follows: first, the angle steel on the conveyor frame 6 is in an open-up state. At this time, the rotating shaft 1901 rotates, so that the electromagnetic magnet on the supporting arm 20 attracts the angle steel, and then the rotating shaft 1901 rotates in the opposite direction. The reverse rotation of the rotating shaft 1901 drives the supporting arm 20 to rotate in the opposite direction. After the supporting arm 20 rotates in the opposite direction, the angle steel will reach the temporary storage table 18. When the angle steel contacts the temporary storage table 18, the electromagnetic magnet no longer attracts the angle steel. After the electromagnetic magnet releases the angle steel, the rotating shaft 1901 drives the supporting arm 20 to rotate again.

[0051] As attached Figure 1 ~AttachedFigure 9 As shown, the base 20 further comprises a supporting table 21, which is arranged at the periphery of the base.

[0052] The supporting table 21 is used for temporarily placing the angle steel 2301 before bending and the angle steel 2302 after bending.

[0053] As shown in the accompanying drawings, the base 20 further comprises a supporting table 21, which is arranged at the periphery of the base. Figure 1 ~ the accompanying drawings Figure 9 Figure 1 Figure 9 Figure 1 Figure 9 As shown, the supporting table 21 is provided with a supporting tray 22.

[0054] The supporting tray 22 is used for placing the angle steel, and is directly placed on the supporting table 21. The supporting tray 22 can be transferred between the supporting table 21 and the lifting warehouse 17.

[0055] The angle steel on the supporting tray 22 can be carried to the temporary storage table 18 by the gripper and the mechanical arm 15 for temporary storage.
