Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a flat steel stamping equipment. Background Technology

[0002] Steel grating, also known as steel grid, is a steel product made by arranging flat steel bars at specific intervals and crossbars, and welding them together to form a grid with square openings. Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, and a rectangular cross-section with slightly blunt edges. Flat steel is often formed by stamping, typically using a hydraulic cylinder and a stamping head to press the flat steel bars onto a forming die.

[0003] However, some existing flat steel stamping and forming devices cannot fix flat steel of different sizes during stamping, resulting in low applicability. This can lead to the flat steel shifting during the stamping process, affecting the stamping effect and threatening the safety of workers. Furthermore, the stamping head often suffers damage due to excessive material strength caused by poor buffering performance during the stamping process, significantly shortening its service life. Therefore, these devices do not meet the current requirements. To address this, we propose a flat steel stamping device. Utility Model Content

In addition, the stamping head is often damaged due to excessive material strength due to poor buffering performance during the stamping process, which greatly shortens the service life of the stamping head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat steel stamping equipment, comprising a base, wherein multiple grooves are evenly arranged on the upper surface of the base, a base plate is installed on the upper surface of the grooves, a first pressure sensor is installed on the inner side of the base plate, side plates are movably connected to the upper sides of the inner walls of the grooves via electric push rods, two clamping plates are symmetrically connected to the opposite sides of the outer surfaces of the two side plates via bidirectional moving mechanisms, a second pressure sensor is installed inside the opposite sides of the two clamping plates, a third pressure sensor is installed below the inside of the opposite sides of the two side plates, an L-shaped plate is installed on the rear end face of the base, a hydraulic rod is installed on the upper surface of the L-shaped plate, a lifting seat is fixedly connected to the lower surface of the hydraulic rod, a square groove is provided on the lower surface of the lifting seat, a buffer seat is provided inside the square groove, the buffer seat and the square groove are connected via a first buffer mechanism and a second buffer mechanism, and multiple pressing dies are evenly installed on the lower surface of the buffer seat.

[0006] Preferably, the first buffer mechanism includes a fixed seat and a slider. The slider is disposed on both sides of the upper end face of the buffer seat through a groove. The slider is movably connected to the inner wall of the groove through a first spring. The upper end face of the fixed seat is fixedly connected to the inner wall of the groove.

[0007] Preferably, the front and rear faces of the fixed base and the slider are each provided with a rotating plate, and the rotating plate is rotatably connected to the fixed base and the slider via a pin.

[0008] Preferably, the second buffer mechanism includes a telescopic sleeve rod, and a second spring is sleeved on the outer surface of the telescopic sleeve rod. The telescopic sleeve rod includes a thick sleeve and a thin sleeve rod, and the thin sleeve rod is inserted into the inner side of the thick sleeve. The upper end face of the telescopic sleeve rod is fixedly connected to the inner wall of the groove, and the lower end face of the telescopic sleeve rod is fixedly connected to the upper end face of the buffer seat.

[0009] Preferably, the bidirectional moving mechanism includes a connecting shaft, which is disposed above one side of the outer surface of the side plate via a strip groove. Threaded rods are installed on both the front and rear faces of the connecting shaft, with the thread directions of the two threaded rods being opposite. A threaded plate is sleeved on the outer surface of the threaded rod, and the outer surface of the threaded plate is fixedly connected to the outer surface of the clamping plate.

[0010] Preferably, a motor is installed behind the strip groove through a cavity, and the output end of the motor is fixedly connected to the rear end face of the threaded rod through a connecting shaft, while the front end face of the other threaded rod is rotatably connected to the inner wall of the strip groove through a bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a second pressure sensor, a third pressure sensor, a first pressure sensor, a side plate, an electric push rod, a bidirectional moving mechanism, and a clamping plate, places the flat steel to be stamped inside the groove, with the flat steel in contact with the bottom plate. When the first pressure sensor measures the pressure, the PLC controller controls the electric push rod and motor to work. The electric push rod drives the side plate to move closer to the flat steel and its outer surface, and the motor drives the threaded rod to rotate. The two threaded plates move simultaneously closer to the outer surface of the flat steel, causing the clamping plate to clamp the flat steel stably. When the second and third pressure sensors measure the pressure, the PLC controller controls the electric push rod and motor to stop working. This utility model can stably clamp flat steel of different sizes and improve the stamping effect.

[0014] 2. This utility model, by setting a first buffer mechanism and a second buffer mechanism, allows the rotating plate to rotate during the stamping process, and the slider to slide inside the groove. The first spring extends and retracts to buffer the movement, and the telescopic sleeve extends and retracts, driving the second spring to extend and retract to buffer the movement. This provides a buffer time and space for the die, which can reduce the excessive reaction force directly and instantaneously received by the die from the flat steel to be formed during stamping. This prevents the die from being damaged due to the excessive strength of the flat steel material during the direct downward stamping process, which helps to ensure the service life of the stamping die and is suitable for widespread application.

[0024] The first buffer mechanism 9 includes a fixed base 906 and a slider 901. The slider 901 is disposed on both sides of the upper end face of the buffer base 6 through a slide groove 902. The slider 901 is movably connected to the inner wall of the slide groove 902 through a first spring 903.

[0025] Rotating plates 905 are provided on the front and rear faces of the fixed base 906 and the slider 901. The rotating plates 905 are rotatably connected to the fixed base 906 and the slider 901 through pins 904, which improves the stability of the rotation of the rotating plates 905.

[0026] The second buffer mechanism 10 includes a telescopic sleeve 1002. A second spring 1001 is sleeved on the outer surface of the telescopic sleeve 1002. The telescopic sleeve 1002 includes a thick sleeve and a thin sleeve, with the thin sleeve inserted into the inner side of the thick sleeve.

[0027] The bidirectional moving mechanism 15 includes a connecting shaft 1504, which is positioned above one side of the outer surface of the side plate 13 via a strip groove 1501.

The motor drives the threaded rod 1503 to rotate, and the two threaded plates 1502 move simultaneously closer to the outer surface of the flat steel, causing the clamping plate 16 to clamp the flat steel stably. When the second pressure sensor 17 and the third pressure sensor 18 detect pressure, the PLC controller will control the electric push rod 14 and the motor to stop working. Through the first buffer mechanism 9 and the second buffer mechanism 10, the stamping process is stabilized. During the process, the rotating plate 905 rotates, and the slider 901 slides inside the groove 902. The first spring 903 extends and retracts to buffer the movement, and the telescopic sleeve 1002 extends and retracts, driving the second spring 1001 to extend and retract to buffer the movement. This provides a buffer time and space for the die 5, which can reduce the excessive reaction force from the flat steel to be formed that the die 5 directly and instantaneously receives during the stamping process. This prevents the die 5 from being damaged due to the excessive strength of the flat steel material during the downward stamping process, which is beneficial to ensuring the service life of the stamping die 5. This invention is suitable for widespread application. It can stably clamp flat steel of different sizes and improve the stamping effect. Furthermore, by setting the first buffer mechanism 9 and the second buffer mechanism 10, it is beneficial to ensure the service life of the stamping die.
