Description

Technical Field

[0001] This invention relates to the field of angle steel straightening machine technology, specifically to an angle steel straightening machine. Background Technology

[0002] An angle steel straightening machine is a device used to straighten or level angle steel, a type of steel with an L-shaped cross-section, commonly used in industries such as construction and machinery manufacturing. The angle steel straightening machine uses the principles of force and deformation to straighten the angle steel to achieve the desired shape and size. It typically consists of a frame, straightening rollers, a transmission device, and a control system, and is widely used in steel structure manufacturing, shipbuilding, bridge construction, and other fields.

[0003] Angle steel is commonly used for support in the construction industry, but it can deform to varying degrees during use, affecting its secondary use. Angle steel may be subjected to incorrect forces during installation, such as being struck with a hammer by a worker, or improper fixing or connection during installation, leading to deformation. Angle steel is also frequently subjected to loads exceeding its design or material load-bearing capacity, such as being subjected to excessively heavy reinforced concrete, causing it to be compressed and deformed, thus impairing its load-bearing capacity.

[0004] In building or concrete structures, angle steel is often used for foundation support or formwork fixing. Cement is poured into the formwork, and cement inevitably splashes onto the surface of the angle steel, where it solidifies. Once solidified, the cement is very hard and difficult to remove. When angle steel is recycled and reused, the cement bulges on the surface, affecting its use and corroding it. Workers usually use a hammer to knock it off, which is time-consuming and laborious. Moreover, hammering increases the risk of deformation and causes secondary damage to the angle steel. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] The angle steel straightening machine provided by this invention has the following beneficial effects:

[0020] 1. This invention utilizes a straightening component. A motor rotates the power shaft, causing a gravity hammer to reciprocate up and down. The gravity hammer strikes the angle steel above the extrusion block. The pressure from the gravity hammer and the extrusion block ensures close contact between the extrusion block and the angle steel. Through the hammer's striking of the angle steel, its shape is adjusted to achieve a straightening effect. By reshaping the angle steel through striking, it can be restored to its original state before deformation, thus enabling reuse and restoring and improving its usability.

[0021] 2. This invention utilizes a straightening component and a lifting component. The gravity hammer moves up and down, striking the angle steel above the extrusion block, which knocks off the cement adhering to the surface of the angle steel. The upward movement of the gravity hammer drives the lifting component to lift the angle steel, causing the cement that has fallen off the surface of the angle steel and the cement pressed under the angle steel to slide down the upper surface of the extrusion block. The lifting component creates a second vibration on the placed angle steel, causing dust and fine cement particles to fall off, thereby effectively removing cement from the surface of the angle steel. This ensures that cement components do not interfere with the use of the angle steel and significantly improves its service life.

[0022] 3. This invention utilizes a transmission assembly. Workers manually place the deformed angle steel onto the conveying cone. The motor rotates the power shaft, causing the deflection column to rotate and slide in the intermittent groove, which in turn rotates the conveying cone, conveying the angle steel forward. As the deflection column moves away from the intermittent groove, the conveying cone stops conveying the angle steel, achieving continuous forward conveying of the angle steel. This ensures that the angle steel moves forward after being hammered and corrected, and the uncorrected parts are hammered again. With the orderly coordination of the correction assembly and the steel lifting assembly, the working efficiency of the machine is improved. Attached Figure Description

[0048] The following is the complete working process and working principle of the above embodiment: The worker places the deformed angle steel onto the conveying cone 2211 by hand, with the front end of the angle steel resting on the extrusion block 31. The worker turns on the external power supply of the motor 211 to power the motor 211, causing the drive shaft 212 to rotate clockwise. The drive shaft 212 drives the drive gear 213 to rotate clockwise. Since the drive gear 213 meshes with the transmission gear 221, the drive gear 213 causes the transmission gear 221 to rotate clockwise, thereby driving the gear that meshes with the transmission gear 221. The rotating disk 223 rotates counterclockwise, causing the spindle block 225, which is fixedly connected to the rotating disk 223, to rotate counterclockwise. This causes the deflection column 226 to rotate counterclockwise and slide in the intermittent groove 228 towards the intermittent shaft 2210. The deflection column 226 presses downward against the inner wall of the intermittent groove 228, causing the intermittent block 227 to rotate counterclockwise. The intermittent block 227 causes the intermittent shaft 2210 to rotate counterclockwise, which in turn causes the conveying cone 2211, which is fixedly connected to the intermittent shaft 2210, to rotate counterclockwise. The conveying cone 2211 contacts the angle steel, generating friction. The angle steel is conveyed forward by friction. As the spindle block 225 moves from an inclined state to a horizontal state, the deflection column 226 stops sliding towards the intermittent axis 2210. The spindle block 225 continues to rotate counterclockwise, causing the deflection column 226 to rotate counterclockwise and slide away from the intermittent axis 2210 in the intermittent groove 228. After the deflection column 226 presses down on the inner wall of the intermittent groove 228, causing the intermittent block 227 to rotate counterclockwise, the deflection column 226 slides out of the intermittent block 227. At this point, the deflection column 226 no longer presses down. The intermittent block 227 stops rotating inside the intermittent groove 228, the conveying cone 2211 stops conveying the angle steel, and the spindle block 225 continues to rotate. When the deflection column 226 slides back into the intermittent groove 228, the conveying cone 2211 conveys the angle steel forward again. The above movement is repeated, and the conveying cone 2211 conveys the angle steel forward intermittently, achieving the effect of continuously conveying the angle steel forward. This ensures that the angle steel moves forward after being hammered and corrected, and the unrepaired parts are hammered again. With the help of the correction component 3 and the steel lifting component 4 working in an orderly manner, the working efficiency of the machine is improved.

[0049] As the power shaft 212 begins to rotate clockwise, driving the power gear 213, the clockwise rotation of the power shaft 212 also drives the power rod 33, which is fixedly connected to it, to rotate clockwise around the connection point with the power shaft 212. The end of the power rod 33 away from the power shaft 212 pulls the connecting rod 34 downward, causing the rocker arm 35 to rotate clockwise around the connection point with the support bracket 36. The end of the rocker arm 35 near the sliding bracket 38 pulls the sliding rod 37 upward, causing the gravity hammer 32 to move upward. At the same time, the conveying cone 2211 conveys the angle steel forward. When the conveying cone 2211 stops conveying the angle steel, the clockwise rotation of the power rod 33 changes from an inclined state to a vertical state, and the gravity hammer 32 stops moving upward. At this time, the connection point between the power rod 33 and the connecting rod 34 moves below the power shaft 212. The power rod 33 continues to rotate clockwise, pushing the connecting rod 34 upward, causing the rocker arm 35 to rotate counterclockwise. The rocker arm 35 moves closer to the sliding bracket. One end of 38 pushes the sliding rod 37 downward, which in turn drives the gravity hammer 32 downward. The gravity hammer 32 strikes the angle steel above the extrusion block 31, correcting the deformed angle steel and removing the hard cement on the surface of the angle steel. The power rod 33 pulls the connecting rod 34 downward, causing the rocker arm 35 to rotate clockwise. The end of the rocker arm 35 near the sliding bracket 38 pulls the sliding rod 37 upward, which in turn drives the gravity hammer 32 upward. At this time, the conveying cone 2211 conveys the angle steel forward again, and the cement slides down the upper surface of the extrusion block 31 to both sides. The above movement is repeated, and the conveying cone 2211 repeatedly strikes the angle steel, correcting the deformed angle steel and removing cement dust from the surface of the angle steel. Through the striking of the angle steel by the gravity hammer 32, its shape is adjusted to achieve the correction effect. By striking and reshaping the angle steel, it can be restored to its original shape before deformation, thereby achieving reuse and restoring and improving its usability.

[0050] When the gravity hammer 32 moves upward, it drives the deflection tube 411, which is fixedly connected to it, to move upward. The deflection tube 411 pushes the fixed tube 414 upward, which in turn drives the lifting claw 413 upward. The two lifting claws 413 lift the angle steel, causing the cement dust that has fallen off between the angle steel and the extrusion block 31 to slide down the upper surface of the extrusion block 31 to both sides. The upward movement of the deflection tube 411 drives the locking block 421 to move upward. The locking block 421 pushes the fixed spring 422 upward, compressing the fixed spring 422. The locking block 421 pushes the protective spring plate 423, which is fixedly connected to it, to move upward. The protective spring plate 423 slides upward in the spring plate groove 426, protecting the spring from moving straight up and down and preventing the middle of the spring from breaking off outward. When the lifting claw 413... When the end near the deflection tube 411 moves upward until it contacts the fixed block 424, the fixed block 424 presses the lifting claw 413, causing the lifting claw 413 to rotate around the deflection tube 411 and release the angle steel. The angle steel slides down from the inclined surface at the bottom of the lifting claw 413, and the lifting claw 413 stretches the retracting claw spring 416, causing the angle steel to fall back onto the upper surface of the pressing block 31. The dust on the surface of the angle steel is shaken off, and the two lifting claws 413 rotate clockwise and counterclockwise, aligning the slot 412 with the locking block 421. The fixing spring 422 is no longer resisted upward by the deflection tube 411, and the fixing spring 422 rebounds and presses the locking block 421 downward, causing the locking block 421 to enter the slot 412. When the gravity hammer 32 moves downward, the surface of the lifting claw 413 moves away from the fixed block 424. However, the locking block 421 is stuck in the slot 412, preventing the lifting claw 413 from rotating counterclockwise to reset. The gravity hammer 32 drives the fixing tube 414 to move downward, which in turn pushes the deflection tube 411 downward, causing the lifting claw 413 to move downward. The fixing spring 422 extends and pushes the locking block 421 downward, keeping the locking block 421 stuck in the slot 412. The locking block 421 pulls the protective spring plate 423 downward, which slides downward in the spring plate slot 426. When the gravity hammer 32 moves downward and approaches the angle steel, the fixing spring 422 returns to its original length from the compressed state. The gravity hammer 32 continues to move downward, and the fixing block 424 pulls the fixing spring 422 upward. The fixing spring 422 pulls the locking block 421 upward, and the locking block 421 is subjected to... The upward pull disengages from the slot 412, the retracting claw spring 416 contracts and pulls the lifting claw 413 to rotate counterclockwise and reset. The lifting claw 413 re-encircles the angle steel, and the gravity hammer 32 continues to move downward to strike the angle steel. After the gravity hammer 32 strikes the angle steel, the above movement is repeated. After striking the angle steel, the angle steel is lifted to shake off cement and dust. The upward movement of the gravity hammer 32 drives the lifting steel assembly 4 to lift the angle steel upward, causing the cement that has fallen off the surface of the angle steel and the cement pressed under the angle steel to slide down the upper surface of the extrusion block 31. The lifting steel assembly 4 creates a second vibration on the placed angle steel, causing dust and fine cement to fall off, thereby effectively removing cement from the surface of the angle steel, ensuring that the cement components do not interfere with the use of the angle steel, and significantly improving the service life of the angle steel.
