Description

[0002] Angle steel, also known as angle iron or long strips of steel with two sides perpendicular to each other, is a type of carbon structural steel. Angle steel has the characteristics of light weight, high strength, large load-bearing capacity, good stability, strong plasticity, and easy installation. At the same time, its cross-sectional shape is uniform and symmetrical, so its moment of inertia, section modulus and resistance moment are all large, which enables it to perform well when subjected to dynamic loads and impact loads. Angle steel may bend and deform during transportation, so it needs to be corrected.

[0003] The existing patent document "CN217432664U Correction Machine for Recovering Deformed Angle Steel" discloses an angle steel correction machine.

It is difficult to fully adapt to this deformation only by using a fixed fixture. At the same time, the angle steel is corrected by multiple impacts.

[0056] The correction support structure 5 includes a slide 501, a support portion 502 and a correction platform 503. The slide 501 is arranged on the guide rail 101 and is slidably connected to the guide rail 101.

According to the technical solution, the correction hammer 604 can be driven to move upward by moving the moving guide rod 603 upward, and the spring 605 can be contracted. The contraction of the spring 605 generates elastic potential energy. When the elastic potential energy is released, the correction hammer 604 can be driven to press downward to hammer the angle steel, thereby realizing the function of hammer correction.

[0058] A connecting rod 606 is fixedly connected to the upper end of the movable guide rod 603, and a roller 607 is rotatably connected to one end of the connecting rod 606. The L-shaped fixing frame 608 is fixedly arranged on the side wall of the fixed bracket 601, and a force control part 609 is rotatably connected to the side wall of the L-shaped fixing frame 608. A driving motor 610 is fixedly connected to the other side of the L-shaped fixing frame 608, and the end of the output shaft of the driving motor 610 is fixedly connected to the force control part 609.

[0059] As a preferred technical solution, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the force control part 609 includes a disk 6091, a contact arm 6092, a fixed block 6093, a fixed plate 6094, a connecting screw 6095, a bevel gear A 6096, a rotating rod 6097, a bevel gear B 6098 and an adjusting disk 6099. The disk 6091 is provided with an inner cavity, and a plurality of contact arms 6092 are slidably connected in the inner cavity of the disk 6091. The contact arm 6092 is provided with an inner cavity, and a fixing block 6093 is fixedly connected in the inner cavity of the contact arm 6092. A fixing plate 6094 is fixedly connected in the inner cavity of the disk 6091. A connecting screw 6095 is rotatably connected at the fixing plate 6094, and one end of the connecting screw 6095 extends to the contact arm 6092. In the inner cavity, the connecting screw 6095 passes through the fixed block 6093 and is threadedly matched with the fixed block 6093, one end of the connecting screw 6095 is fixedly connected to a bevel gear A6096, the center position of the disk 6091 is rotatably connected to a rotating rod 6097, the rotating rod 6097 is fixedly connected to a bevel gear B6098, the bevel gear B6098 and the bevel gear A6096 are meshed with each other, the outer wall of the disk 6091 is rotatably connected to an adjusting disk 6099, the adjusting disk 6099 is fixedly connected to the rotating rod 6097, through the technical solution, the operation of the driving motor 610 can drive the force control part 609 to rotate, thereby causing the contact arm 6092 to rotate, such as Figure 5 From the perspective of, when the contact arm 6092 rotates clockwise, the contact arm 6092 can contact the roller 607 and push the roller 607 upward. The upward movement of the roller 607 can drive the correction hammer 604 to move upward, and the spring 605 can contract to accumulate elastic potential energy. As the contact arm 6092 continues to rotate, it will eventually separate from the roller 607. At this time, the correction hammer 604 is pressed down by the elastic potential energy of the spring 605 to perform hammer correction. As the force control part 609 continues to rotate, it can continuously drive the correction hammer 604 to hammer for correction. When the force of the hammer needs to be adjusted, the hammer force can be controlled by adjusting the extension amount of the contact arm 6092. When the arm 6092 is extended longer, the distance that the roller 607 is pushed to move upward is also longer, thereby increasing the contraction stroke of the spring 605 and increasing the hammering force. Conversely, when the contact arm 6092 is extended shorter, the distance that the roller 607 is pushed to move upward is short, the deformation of the spring 605 is short, and the hammering force is also small. The rotating rod 6097 can be driven to rotate by rotating the adjusting disk 6099, and the rotation of the rotating rod 6097 can drive the bevel gear B6098 to rotate, and then drive the bevel gear A6096 to rotate, thereby driving the connecting screw 6095 to rotate, and then the rotation of the connecting screw 6095 drives the fixing block 6093 to move, and then drives the contact arm 6092 to move, such as Figure 6From the perspective of the embodiment, when the rotating rod 6097 rotates counterclockwise, the contact arm 6092 contracts inward, thereby reducing the force of the hammer correction;

[0060] A plurality of limiting holes are provided on the arc-shaped wall of the adjusting disk 6099, the fixing rod 611 is fixedly arranged at the lower position of the adjusting disk 6099, a locking rod 612 is slidably connected in the inner cavity of the fixing rod 611, the top end of the locking rod 612 extends into the limiting hole of the adjusting disk 6099, and a locking bolt 613 is threadedly connected at the side wall of the fixing rod 611. Through the technical solution, the setting of the locking rod 612 can play the function of fixing the adjusting disk 6099, and when the force control part 609 rotates to drive the correction When the hammer head 604 is performing hammering correction, the disc 6091 is rotating. At this time, the adjusting disc 6099 is fixed, so that the rotating rod 6097 rotates counterclockwise relative to the disc 6091 in the inner cavity of the disc 6091. Due to the counterclockwise rotation of the disc 6091, the contact arm 6092 gradually shrinks inward during the continuous rotation process. As a result, the hammering force gradually decreases due to the gradual inward shrinkage of the contact arm 6092, thereby realizing the function of reducing the hammering force as the correction proceeds and avoiding damage caused by over-correction.

[0061] For further technical solutions, see Fig. 9 and Fig.10 As shown, the self-cleaning unit 7 includes a fixed cylinder 701, a movable connecting rod 702, a piston 703, an output hose 704, an air nozzle 705 and an input pipe 706.

One end of the movable connecting rod 702 is fixedly connected to the upper surface of the piston 703. The other end of the movable connecting rod 702 penetrates the upper wall of the inner cavity of the fixed cylinder 701 and extends outside the wall. The top end of the movable connecting rod 702 is fixedly connected to the connecting rod 606. Through this technical solution, when the angle steel is hammered and corrected, as the connecting rod 606 reciprocates up and down, the movable connecting rod 702 can be driven to reciprocate up and down, thereby driving the piston 703 to slide up and down in the inner cavity of the fixed cylinder 701.

[0062] One end of an output hose 704 is fixedly connected to the bottom side of the inner cavity of the fixed cylinder 701, and the other end of the output hose 704 is connected to an air nozzle 705, and the air nozzle 705 is fixedly arranged on the fixed bracket 601.

An input one-way valve is installed at the input pipe 706. When the piston 703 moves upward, air can be drawn in through the input pipe 706, and in the process of the falling of the correction hammer head 604, the piston 703 is pressed downward, so that the gas in the inner cavity of the fixed cylinder 701 is output through the output hose 704 and sprayed through the air nozzle 705, which plays a role of blowing and cleaning the surface of the angle steel, avoiding the phenomenon of indentations and bumps caused by debris particles on the surface of the angle steel during correction, realizing the function of automatic cleaning, without the need for an additional power source, and convenient and flexible to use.
