Description

Technical Field

[0001] The utility model relates to the technical field of steel strip punching processing, in particular to a continuous punching machine for connecting steel strips. Background Art

[0002] The connecting steel belt is a connecting piece used when assembling wooden packaging boxes. It is used to fix two adjacent wooden board sides together. In order to facilitate fixing the connecting steel belt on the surface of the wooden board, a hole structure needs to be processed on the surface of the connecting steel belt before using it.

[0003] The holes in the connecting steel strip are generally punched out. When a traditional punching machine is in use, the residual material on the surface of the punched connecting steel strip is easy to fall onto the punching table. If it is not cleaned up in time, it will affect the subsequent hole processing effect of the connecting steel strip. If the residual material on the surface of the punching table is cleaned up, the hole processing of the connecting steel strip will be interrupted, affecting the efficiency of the hole processing on the surface of the connecting steel strip. Utility Model Content

[0023] The telescopic cylinder is fixedly mounted on the upper surface of the mounting seat. The telescopic cylinder is a hydraulic cylinder or a pneumatic cylinder. The telescopic rod of the telescopic cylinder is fixedly connected to the mounting block.

[0024] The telescopic cylinder can be used to adjust the position of the upper roller up and down, thereby adjusting the distance between the upper roller and the lower roller.

[0040] Two rows of punching modules 51 are installed in the box above the machine 1, and a punching rod is installed on the lower end surface of the punching module 51. The punching rod is installed using the punching module 51, and two longitudinally distributed punching modules 51 are fixedly installed on the surface of the same support plate 5 at the same time; hydraulic rods 6 are installed on the side walls on both sides of the box above the machine 1, and a pressing plate 61 is fixedly installed on the lower end of the hydraulic rod 6, and the pressing plate 61 is fixedly connected to the support frame 3.

[0041] A support platform 7 is fixedly mounted on the upper surface of the machine platform 1 . A pressing groove 71 is provided on the upper surface of the support platform 7 . The width of the pressing groove 71 matches the width of the connecting steel strip. The connecting steel strip to be pressed is placed in the pressing groove 71 .

[0042] Two rows of forming holes 72 are provided on the bottom surface of the pressing groove 71, and there is a corresponding forming hole 72 just below the pressing rod. The pressing rod cooperates with the forming hole 72 to perform pressing and forming processing on the surface of the connecting steel belt; the number of holes in a row of forming holes 72 is greater than the number of hole pressing rods in a row; a driving motor is installed inside the slide 4, and the driving motor is used to adjust the lateral position of the slide 4 on the surface of the guide rail 31, and the driving motor is used to adjust the spacing between two adjacent slides 4, thereby changing the distance between two adjacent pressing rods, and cooperating with the forming hole 72, the hole spacing of the holes on the surface of the connecting steel belt can be changed.

[0043] A support block 8 is installed inside the forming hole 72 for sliding up and down, and a return spring 81 is provided between the lower surface of the support block 8 and the inner wall of the forming hole 72. A suction rod 9 is installed inside the support block 8 to absorb the residual material dropped from the pressing hole on the surface of the connecting steel strip to prevent the residual material from falling into the pressing groove 71.

[0044] The interior of the suction rod 9 is a hollow tube, the upper end of the hollow tube is connected to the pressing groove 71, and a sealing gasket 91 is fixedly installed on the upper end of the suction rod 9. The sealing gasket 91 protrudes from the upper surface of the support block 8. The design of the sealing gasket 91 can increase the contact sealing effect between the connecting steel belt and the upper end of the suction rod 9.

[0045] A cylinder 10 is fixedly installed on the bottom surface of the forming hole 72, and a piston plate 92 is sealed and slidably installed inside the cylinder 10. The lower end of the suction rod 9 is fixedly connected to the piston plate 92, and a limit block 921 is fixedly installed on the upper surface of the piston plate 92 for limiting the upward position of the suction rod 9. The hollow tube inside the suction rod 9 is connected to the space inside the cylinder 10 above the piston plate 92. A through hole is opened on the bottom surface of the cylinder 10, and the space pressure inside the cylinder 10 below the piston plate 92 is the same as the atmospheric pressure.

[0046] When the punching rod moves downward and pushes the remaining material of the connected steel strip into the forming hole 72, the remaining material pushes the support block 8 and the suction rod 9 to move downward, and at the same time, the lower surface of the remaining material contacts the sealing gasket 91. When the suction rod 9 moves downward, it pushes the piston plate 92 to move together, and the air pressure in the space inside the cylinder 10 above the piston plate 92 drops, thereby generating negative pressure in the hollow tube inside the suction rod 9. The adsorption effect of the negative pressure is used to make the remaining material adsorbed on the surface of the sealing gasket 91, so as to avoid the remaining material being brought into the pressing groove 71 when the punching rod is reset.

[0047] A material guide channel 73 is opened on both sides of the forming hole 72, and the suction rod 9 is installed inside the support block 8 for sliding up and down. A return spring 101 is provided between the piston plate 92 and the bottom surface inside the cylinder 10. The speed at which the support block 8 moves up and returns to its original position is lower than the speed at which the suction rod 9 moves up and returns to its original position.

[0048] The diameter of the support block 8 is smaller than the aperture of the forming hole 72 . A group of stops 721 are rotatably installed on the inner wall of the forming hole 72 . The stops 721 are located on the lower side of the material guide channel 73 . The stops 721 are designed to be tilted downward, and a spring is provided between the stops 721 and the inner wall of the forming hole 72 .

[0049] When the support block 8 and the suction rod 9 are reset, the upper end of the suction rod 9 lifts up the residual material. When the side of the residual material moves to the position of the stopper 721, the residual material will overturn. At the same time, the air pressure inside the suction rod 9 returns to the atmospheric pressure. When the overturned residual material moves to the position of the material guide channel 73, it slides into the material guide channel 73, and the residual material is collected in a centralized manner by using the material guide channel 73.

[0050] A steel belt input assembly 11 and a steel belt output assembly 12 are respectively provided at both ends of the support platform 7. The steel belt input assembly 11 and the steel belt output assembly 12 both include a mounting seat 13, a lower roller 131, an upper roller 132 and a telescopic cylinder 133. The mounting seat 13 is U-shaped, and the lower roller 131 is rotatably mounted on the inner wall of the mounting seat 13. The uppermost surface of the lower roller 131 is not lower than the bottom surface of the pressure groove 71, and the lower roller 131 is driven to rotate by a motor device installed on the side surface of the mounting seat 13.

[0051] Both ends of the upper roller 132 are rotatably mounted with mounting blocks, and the mounting blocks are slidably mounted inside the mounting seat 13 up and down; the telescopic cylinder 133 is fixedly mounted on the upper surface of the mounting seat 13, and the telescopic cylinder 133 is a hydraulic cylinder or a pneumatic cylinder, and the telescopic rod of the telescopic cylinder 133 is fixedly connected to the mounting block.

[0052] The telescopic cylinder 133 can be used to adjust the position of the upper roller 132 up and down, thereby adjusting the distance between the upper roller 132 and the lower roller 131. When the connecting steel belt enters between the lower roller 131 and the upper roller 132, the upper roller 132 is used to press the connecting steel belt, and the motor equipment is used to drive the lower roller 131 to rotate. The lower roller 131 cooperates with the upper roller 132 to convey the connecting steel belt.

[0053] Working principle of punching machine:

[0054] First, use the steel belt input assembly 11 to transport the connecting steel belt to the pressing groove 71. When the connecting steel belt moves to a suitable position, start the hydraulic rod 6. The hydraulic rod 6 drives the support frame 3 to move downward through the pressing plate 61. The support frame 3 drives the punching module 51 in the support plate 5 to move downward together. The punching module 51 drives the punching rod to move in the direction of the connecting steel belt.

[0055] After the punching rod contacts the surface of the connecting steel strip, the punching rod cooperates with the forming hole 72 to punch a hole on the surface of the connecting steel strip. At the same time, the residual material after the hole is formed on the surface of the connecting steel strip enters the forming hole 72 and continues to move downward under the action of the punching rod. The residual material pushes the support block 8 and the suction rod 9 to move downward. At the same time, the lower surface of the residual material contacts the sealing gasket 91. When the suction rod 9 moves downward, it pushes the piston plate 92 to move together. The air pressure in the space inside the cylinder 10 above the piston plate 92 decreases, thereby generating negative pressure in the hollow tube inside the suction rod 9. The adsorption effect of the negative pressure is used to make the residual material adsorbed on the surface of the sealing gasket 91, thereby preventing the residual material from being brought into the pressing groove 71 when the punching rod is reset.

[0056] When the support block 8 and the suction rod 9 are reset, the upper end of the suction rod 9 lifts up the residual material. When the side of the residual material moves to the position of the stopper 721, the residual material will overturn. At the same time, the air pressure inside the suction rod 9 returns to the atmospheric pressure. When the overturned residual material moves to the position of the material guide channel 73, it slides into the material guide channel 73, and the residual material is collected in a centralized manner by using the material guide channel 73.

[0057] After the holes on the surface of the connecting steel strip in the pressing groove 71 are processed, the steel strip input assembly 11 and the steel strip output assembly 12 are continued to be used to transport the processed connecting steel strip out of the pressing groove 71, and the connecting steel strip to be processed is transported into the pressing groove 71, and the above operation is continued, thereby realizing continuous hole pressing processing of the connecting steel strip.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
