Description

Technical Field

[0001] This invention relates to the field of steel transfer technology, specifically a feeding mechanism for steel processing. Background Technology

[0002] Steel: Steel ingots, billets, or finished steel products are processed under pressure to achieve various shapes, sizes, and properties. Steel is an important category of metal plastic processing products. Of the total steel production, except for a small portion formed by casting and powder metallurgy, the vast majority is plastically processed into steel products. In addition to having a specified chemical composition, good surface quality, and precise geometric dimensions, steel products possess sufficient tensile strength, yield strength, hardness, toughness, and other mechanical properties. Some also exhibit weldability, ease of forming, and certain special physicochemical properties. Based on their cross-sectional shape, steel products can be divided into four main categories: profiles, plates, pipes, and metal products.

[0003] When processing steel, it is usually hoisted by a hoisting mechanism, which is inefficient, requires manual assistance, and is labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems and provide a feeding mechanism for steel processing, which facilitates the transfer and feeding of steel and reduces labor intensity.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A steel processing feeding mechanism includes a conveying mechanism for conveying steel and a transfer mechanism for transferring steel.

[0007] The transfer mechanism includes a first rotating shaft, a turntable disposed on the upper end of the first rotating shaft, and a drive mechanism for driving the first rotating shaft to reciprocate. The turntable is evenly provided with three positioning slots. A first swing arm is provided between the two positioning slots on the left end, and drive slots are provided at both ends of the positioning slot on the right end. A lifting rod is provided on the first swing arm. When the first rotating shaft rotates, the lifting rod is driven to rise and fall through the linkage mechanism. A pneumatic gripper for gripping steel is provided at the lower end of the lifting rod.

[0008] The linkage mechanism includes a first bracket, a support plate at the upper end of the first bracket, and a crossbar at the side of the lifting rod. The support plate has a protrusion, and the rear end of the crossbar has a roller supported on the support plate. A tension spring is provided between the upper end of the lifting rod and the first swing arm.

[0009] The driving mechanism includes a second bracket, a drive shaft mounted on and rotating on the second bracket, and second rotating shafts at both ends of the drive shaft. The two ends of the drive shaft are connected to the corresponding second rotating shafts via bevel gears. A second swing arm is provided at the upper end of the front second rotating shaft, and a first drive rod that cooperates with the drive groove is provided at one end of the outer side of the second swing arm. A first positioning plate and a second positioning plate that cooperate with the positioning groove are provided at the upper end of the rear second rotating shaft. A third swing arm is provided between the first positioning plate and the second positioning plate, and a second drive rod that cooperates with the drive groove is provided at one end of the outer side of the third swing arm.

[0010] Furthermore, the first swing arm is provided with a guide sleeve, and the lifting rod passes through the guide sleeve and is slidably connected to the guide sleeve.

[0011] Furthermore, both the lifting rod and the guide sleeve are rectangular.

[0012] Furthermore, the upper end of the lifting rod is provided with a connecting rod, the upper end of the tension spring is connected to the connecting rod, and the lower end of the tension spring is connected to the first swing arm.

[0013] Furthermore, the second bracket is equipped with a motor, the output shaft of the motor is equipped with a first pulley, and the drive shaft is equipped with a second pulley. The first pulley and the second pulley are connected by a belt.

[0014] Furthermore, the included angle of the first positioning plate is greater than the included angle of the second positioning plate.

[0015] Furthermore, the conveying mechanism includes a third support and a conveyor belt mounted on and operating on the third support.

[0016] Furthermore, guide plates are provided on both the left and right sides of the third bracket.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention includes a conveying mechanism for transporting steel and a transfer mechanism for transferring steel. During operation, the conveying mechanism continuously transports steel backwards, and then the transfer mechanism picks up the steel and places it at the processing station, thus achieving automatic steel feeding with a compact cycle, high efficiency, and no need for manual assistance, reducing labor intensity.

[0019] 2. The transfer mechanism of this invention includes a first rotating shaft, a turntable disposed on the upper end of the first rotating shaft, and a drive mechanism for driving the first rotating shaft to reciprocate. The turntable has three evenly spaced positioning slots. A first swing arm is disposed between the two positioning slots on the left end, and drive slots are disposed at both ends of the positioning slot on the right end. A lifting rod is disposed on the first swing arm. When the first rotating shaft rotates, the lifting rod is driven to rise and fall via a linkage mechanism. A pneumatic gripper for gripping steel is disposed at the lower end of the lifting rod. During operation, the drive mechanism drives the first rotating shaft to reciprocate continuously, and the first swing arm rotates accordingly. When the first swing arm rotates to the left and right ends, the lifting rod descends to the bottom, facilitating the pneumatic gripper to grip the steel. When the first swing arm swings, under the action of the linkage mechanism, the lifting rod first rises and remains stationary. Then, when the first swing arm swings to the rightmost end, the lifting rod descends, releasing the steel. When the pneumatic gripper grips the steel and swings, it rises first, without interfering with the conveying mechanism.

[0020] 3. The linkage mechanism in this invention includes a first bracket, a support plate at the upper end of the first bracket, and a crossbar on the side of the lifting rod. The support plate has a protrusion, and the rear end of the crossbar has a roller supported on the support plate. A tension spring is provided between the upper end of the lifting rod and the first swing arm. When the first swing arm swings, the roller is always in contact with the support plate under the action of the tension spring. When the roller passes the protrusion, the lifting rod moves upward against the elastic force of the tension spring. Through mechanical linkage, the swing of the first swing arm and the lifting of the lifting rod are linked, which has good reliability and does not require a separate drive mechanism to drive the lifting rod to move up and down, thus reducing costs.

[0028] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0029] like Figure 1 As shown, a steel processing feeding mechanism includes a conveying mechanism for transporting steel and a transfer mechanism for transferring steel. During operation, the conveying mechanism continuously transports steel backwards, and then the transfer mechanism picks up the steel and places it at the processing station, thus achieving automatic steel feeding. This process is efficient, with a tight cycle, and requires no manual assistance, reducing labor intensity.

[0030] like Figures 2 to 4 As shown, the transfer mechanism includes a first rotating shaft 1, a turntable 2 mounted on the upper end of the first rotating shaft 1, and a drive mechanism for driving the first rotating shaft 1 to reciprocate. The turntable 2 has three evenly spaced positioning slots 3. A first swing arm 4 is positioned between the two positioning slots 3 on the left end, and drive slots 5 are located at both ends of the positioning slots 3 on the right end. A lifting rod 6 is mounted on the first swing arm 4. When the first rotating shaft 1 rotates, the lifting rod 6 is raised and lowered via a linkage mechanism. A pneumatic gripper 7 for gripping steel is located at the lower end of the lifting rod 6. During operation, the drive mechanism drives the first rotating shaft 1 to reciprocate continuously, causing the first swing arm 4 to rotate accordingly. When the first swing arm 4 rotates to the left or right ends, the lifting rod 6 descends to its lowest point, facilitating the gripper 7 to grip the steel. When the first swing arm 4 swings, under the action of the linkage mechanism, the lifting rod 6 first rises and remains stationary. Then, when the first swing arm 4 swings to its rightmost end, the lifting rod 6 descends, releasing the steel. When the pneumatic gripper 7 grips the steel and swings, it rises first, preventing interference with the conveying mechanism.

[0031] like Figure 3 and Figure 4As shown, the linkage mechanism includes a first bracket 8, a support plate 9 located at the upper end of the first bracket 8, and a crossbar 10 located on the side of the lifting rod 6. A first rotating shaft 1 passes through the first bracket 8 and is rotatably connected to the first bracket 8 via a bearing. The support plate 9 has a protrusion 11. The rear end of the crossbar 10 has a roller 12 supported on the support plate 9. A tension spring 13 is provided between the upper end of the lifting rod 6 and the first swing arm 4. When the first swing arm 4 swings, the roller 12 is always in contact with the support plate 9 under the action of the tension spring 13. When the roller 12 passes the position of the protrusion 11, the lifting rod 6 moves upward against the elastic force of the tension spring 13. Through mechanical linkage, the swing of the first swing arm 4 and the lifting of the lifting rod 6 are linked, which has good reliability and does not require a separate drive mechanism to drive the lifting rod to move up and down, resulting in low cost.

[0032] like Figure 5 As shown, the drive mechanism includes a second bracket 14, a drive shaft 15 mounted on and rotating on the second bracket 14, and second rotating shafts 16 located at both ends of the drive shaft 15. The axis of the second rotating shafts 16 is vertical, and the shafts 16 pass through the second bracket 14 and are rotatably connected to the second bracket 14 via bearings. The axis of the drive shaft 15 is horizontal, and both ends of the drive shaft 15 are supported on the second bracket 14 via bearings. The two ends of the drive shaft 15 are connected to the corresponding second rotating shafts 16 via bevel gears. A second swing arm 17 is provided at the upper end of the shaft 16. One end of the inner side of the second swing arm 17 is fixed to the upper end of the second rotating shaft 16. One end of the outer side of the second swing arm 17 is provided with a first drive rod 18 that cooperates with the drive groove 5. The upper end of the rear end of the second rotating shaft 16 is provided with a first positioning plate 19 and a second positioning plate 20 that cooperate with the positioning groove 3. A third swing arm 21 is provided between the first positioning plate 19 and the second positioning plate 20. One end of the inner side of the third swing arm 21 is fixed to the rear end of the second rotating shaft 16. One end of the outer side of the third swing arm 21 is provided with a second drive rod 22 that cooperates with the drive groove 5. When the drive shaft 15 rotates, the second shafts 16 on both sides rotate in the opposite direction. When the second drive rod 22 engages with the drive groove at the front end, it drives the first swing arm 4 to swing from back to front. After the second drive rod 22 separates from the drive groove, the first positioning plate 19 engages with the corresponding positioning groove, the first swing arm 4 remains stationary, and the pneumatic gripper 7 clamps the steel. When the first drive rod 18 engages with the drive groove at the rear end, the first swing arm 4 swings from front to back, realizing the transfer of the steel. The second positioning plate 20 engages with the corresponding positioning groove, the first swing arm 4 remains stationary, and the pneumatic gripper 7 releases the steel.

[0033] like Figure 3 As shown, the first swing arm 4 is provided with a guide sleeve 23, and the lifting rod 6 passes through the guide sleeve 23 and is slidably connected to the guide sleeve 23.

[0034] Both the lifting rod 6 and the guide sleeve 23 are rectangular to prevent the lifting rod 6 from rotating when the first swing arm 4 swings.

[0035] like Figure 3 As shown, the upper end of the lifting rod 6 is provided with a connecting rod 24, the upper end of the tension spring 13 is connected to the connecting rod 24, and the lower end of the tension spring 13 is connected to the first swing arm 4.

[0036] like Figure 1 As shown, the second bracket 14 is equipped with a motor 25, the output shaft of the motor 25 is equipped with a first pulley 26, and the drive shaft 15 is equipped with a second pulley 27. The first pulley 26 and the second pulley 27 are connected by a belt 28, and the motor 25 drives the drive shaft 15 to rotate through the belt 28.

[0037] like Figure 2 As shown, the included angle of the first positioning plate 19 is greater than the included angle of the second positioning plate 20.

[0038] like Figure 1 As shown, the conveying mechanism includes a third support 29 and a conveyor belt 30 mounted on the third support 29 and running on the third support 29, through which steel is continuously conveyed.

[0039] The third support 29 is provided with guide plates 31 on both the left and right sides, which guide the movement of the steel.
