Description

Technical Field

[0001] The invention relates to the technical field of bending equipment, in particular to an angle steel bending and cutting device. Background Art

[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, and warehouse shelves.

[0003] At present, in the production of angle steel bending, most of the methods used are to first punch a V-shaped bend at the bend of the angle steel and then bend it. However, in this method, the stamping and bending of the angle steel are processed separately by two machines, which results in the angle steel needing to be moved to the bending machine for repositioning after stamping, affecting efficiency. In addition, most existing bending machines use bending punches to bend angle steels. The head angle of such bending punches is mostly fixed. Bending angle steels of different angles requires replacing punches of different angles. This results in the need to replace the bending punches when bending angle steels of different angles, affecting the bending efficiency.

[0004] Therefore, we make improvements to this and propose an angle steel bending and cutting device. Summary of the invention

[0050] A take-out groove 38 is provided in the middle of one end of the conveying frame 1 close to the bending component 6 .

[0051] Working principle of the present invention:

[0052] Place the angle steel on the angle steel slide rail 2 so that the inner cavity of the angle steel fits the upper part of the angle steel slide rail 2, and then push the angle steel so that the front end of the angle steel is placed under the conveying component 3 at the left end of the conveying frame 1;

[0053] All conveying components 3 are started, and the hydraulic cylinder D29 drives the rotating wheel seat 26 to descend. The head of the conveying wheel 27 of the conveying component 3 at the left end of the conveying frame 1 is elastically fitted with the outer wall of the angle steel through the nitrogen spring 30, and the heads of the conveying wheels 27 of the two conveying components 3 adjacent to the corner cutting component 5 are elastically fitted with the outer wall of the angle steel slide rail 2 through the nitrogen spring 30. The stepper motor 28 is started to drive the conveying wheel 27 to rotate, and the conveying wheel 27 of the conveying component 3 at the left end of the conveying frame 1 drives the angle steel to move, and the conveying wheels 27 of the two conveying components 3 adjacent to the corner cutting component 5 idle on the upper part of the angle steel slide rail 2. When the angle steel moves to the two conveying components 3 adjacent to the corner cutting component 5, under the push of the conveying component 3 at the left end of the conveying frame 1, the angle steel squeezes into the bottom of the conveying wheels 27 of the two conveying components 3 adjacent to the corner cutting component 5, and drives the angle steel to move on the angle steel slide rail 2.

[0054] When the length of the angle steel passing through the cutting component 4 reaches the set length, the stepper motors 28 of all the conveying components 3 stop working, and the hydraulic cylinder E34 of the cutting component 4 starts, driving the punching knife 33 to move downward, and the punching knife 33 enters the punching groove 36, and cuts off the angle steel at the same time, and then, the hydraulic cylinder E34 drives the punching knife 33 to rise.

[0055] The two conveying components 3 adjacent to the corner cutting component 5 continue to drive the cut angle steel to move. When the preset bending opening position of the angle steel reaches directly below the corner cutting component 5, the stepper motor 28 of the two conveying components 3 adjacent to the corner cutting component 5 stops working, and the hydraulic cylinder A8 drives the mounting block 9 and the punching block 10 to move downward. The punching strip 12 in the V-groove of the punching block 10 cooperates with the punching bevel groove 37 to punch out the bending opening on the outer wall of the angle steel. The air avoidance groove A13 can prevent the punching strip 12 from completely cutting the angle steel when cutting the angle steel.

[0056] After the angle steel is cut, the hydraulic cylinder A8 drives the mounting block 9 and the punching block 10 to rise. In the initial state, the positioning block 16 of the bending component 6 is fitted with the right end of the angle steel slide rail 2, and the stepper motor 28 of the conveying component 3 at the right end of the angle steel slide rail 2 is started to move the angle steel after the cutting is completed to the positioning block 16. When the bending mouth of the angle steel moves to the limiting wheel 18 of the bending component 6, the limiting wheel 18 is placed in the bending mouth of the angle steel, and the positioning block 16 cooperates with the limiting wheel 18 to position the bending mouth of the angle steel. At this time, the stepper motor 28 of the conveying component 3 at the right end of the angle steel slide rail 2 stops working. At the same time, the hydraulic cylinder D29 of the two conveying components 3 adjacent to the angle cutting component 5 drives the rotating wheel seat 26 and the conveying wheel 27 to rise, so that the angle steel after the cutting is completed is separated from the conveying component 3;

[0057] The hydraulic cylinder B19 drives the bending block 15 to move downward, and the V-shaped grooves on the side walls of the bending block 15 are placed on the outer wall of the angle steel. The V-shaped grooves of the bending block 15 are symmetrically arranged on both sides of the bending opening of the angle steel and are arranged away from the bending opening. The hydraulic cylinder B19 stops working, and the bending component 6 is moved to the front end of the conveying slide rail 20 through the hydraulic cylinder C23, so that the angle steel after the angle cutting is completed is separated from the angle steel slide rail 2;

[0058] The hydraulic cylinder B19 continues to drive the bending block 15 to move downward. Under the action of the hydraulic cylinder B19, the bending block 15 applies pressure to the angle steel. The V-grooves on the side walls of the bending block 15 apply pressure to the outer walls of the angle steel on both sides of the bending mouth of the angle steel. As the bending block 15 slowly descends, the top of the bending mouth begins to bend, and the inner wall of the angle steel uses the outer edges of the upper ends of the positioning block 16 as support points to close the opposite sides of the bending mouth using the lever principle. During the bending process, the inner wall of the angle steel and the outer edges of the upper ends of the positioning block 16 are slidably arranged. After the bending is completed, the position of the bending mouth is located in the inner cavity of the bending block 15 and the upper part of the positioning block 16.

[0059] After the angle steel is bent, the hydraulic cylinder B19 with the bending block 15 rises, and then the bent angle steel is taken out through the taking-out groove 38.
