[0034] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0035] Please refer to Figures 1 to 6 As shown, the multi-hole synchronous punching device for a steel tube table top of the present invention comprises a support base 1 and a bearing base 11 fixed to the top of the support base 1, and a driving element 2 connected to the support base 1 is connected to the top of the bearing base 11;

[0036] The upper surface of the support base 1 is provided with a conveying trough 13, on which a conveying element 3 for conveying the steel pipe is provided, and on both sides of the conveying element 3 are provided support elements 4 for connecting to the support base 1. In actual implementation, the steel pipe component on the steel pipe table to be punched is placed at one end of the conveying trough 13, and the conveying element 3 is activated to slide the steel pipe toward the inside of the conveying trough 13, thereby completing the automatic feeding of the steel pipe. At the same time, the conveying element 3 controls the depth of the steel pipe input and allows the steel pipe to stop at different positions according to the punching of the steel pipe, so as to meet the requirements of multi-hole punching at the corresponding position.

[0037] Optionally, the conveying element 3 includes a conveying roller 31 rotatably arranged in the conveying trough 13, one side of the conveying roller 31 is movably connected to the side wall of the conveying trough 13 through a bearing, and the other end is fixed with a transmission shaft 32 and movably assembled with the support base 1;

[0038] The surfaces of the transmission shafts 32 on the multiple conveying rollers 31 are collectively equipped with a driving mechanism. In actual implementation, when the steel pipe components are placed on the steel pipe table, the driving mechanism is activated to drive the transmission shafts 32 to rotate. Since the transmission shafts 32 are connected to the conveying rollers 31, the multiple conveying rollers 31 will also rotate synchronously to convey the steel pipes thereon.

[0039] Optionally, the drive mechanism includes a pulley 33 connected to the surface of the transmission shaft 32, with a transmission belt 34 being provided on the surfaces of the plurality of pulleys 33. One side of one of the pulleys 33 is connected to a servo motor 35 fixed to the support base 1. In actual implementation, the servo motor 35 is activated to cause its output end to rotate a certain pulley 33. During the rotation of the pulley 33, the pulley 33 drives the synchronous rotation of the plurality of pulleys 33 via the transmission belt 34 thereon. The rotation of the plurality of pulleys 33 drives the rotation of the plurality of transmission shafts 32 and the ground conveying rollers 31 thereon, thereby satisfying the conveying movement of the steel pipe.

[0040] Optionally, the support element 4 includes a support rod 41 slidably arranged on the support seat 1, a connecting seat 42 connected to one end of the support rod 41, and a resistance ball 43 movably embedded in the connecting seat 42, wherein a spring 44 is sleeved on the surface of the support rod 41, one end of the spring 44 is connected to the surface of the connecting seat 42, and the other end is connected to the surface of the support seat 1;

[0041] The other end of the support rod 41 is fixed with a limit plate 45, and one end of the contact ball 43 is pressed against the surface of the steel pipe for positioning by the action of the spring 44. In actual implementation, when the steel pipe component on the steel pipe table is placed inside the conveying trough 13, the contact ball 43 inside the support rod 41 and the connecting seat 42 thereon will press against the surface of the steel pipe due to the action of the spring 44. Since there are contact balls 43 on both sides of the steel pipe, the steel pipe is kept in the middle position. Since the contact ball 43 presses against the upper half of the steel pipe, the steel pipe subjected to the resistance force will press downward, thereby increasing the contact force between the steel pipe and the conveying roller 31 to meet the normal conveying movement of the steel pipe during conveying by the conveying roller 31. Since the contact ball 43 and the connecting seat 42 are mutually movable, the resistance force of the contact ball 43 will not affect the sliding conveying of the steel pipe itself.

[0042] Optionally, the driving element 2 includes a connecting plate 21 provided above the bearing seat 11 and guide rods 22 slidably provided at the four corners of the connecting plate 21;

[0043] One end of each of the four guide rods 22 is fixed to the corresponding supporting seat 11 below, and a return spring 23 sleeved on the surface of the guide rod 22 is commonly connected between the connecting plate 21 and the top of the guide rod 22. The driving element 2 also includes a hydraulic push rod 24 connected to the center of the top of the connecting plate 21 and a support frame 25 connected to the surface of the hydraulic push rod 24 and fixed to the support seat 1. A punching terminal 26 is fixed at the center of the lower surface of the connecting plate 21, and a punching slot 27 for the punching terminal 26 to pass through is opened on the supporting seat 11. In actual implementation, after the steel pipe is input into the conveying trough 13, the hydraulic push rod 24 is activated so that its output end drives the connecting plate 21 to slide toward the punching seat 12, so that the punching terminal 26 passes through the punching slot 27 to punch the steel pipe.
