Description

Technical Field

[0002] Metal mesh is usually made of metal thin plates, on which some slits are made according to the arrangement of staggered parallel short dashes.

During the punching process, the metal mesh is located inside the lower mold 13 at the upper end of the lower die base 16, thereby achieving the effect of facilitating the punching of the metal mesh.

When it moves to a suitable position, the bearing 37 is sleeved on the surface of the screw 34 and fixed with the second nut 17, so that the connecting rod 18 drives the feeding crank shaft 19 to move, thereby achieving the effect of providing power for perforating the metal mesh.

[0029] refer to Figure 4 A connecting rod 18 is fixedly connected to the surface of the bearing 37, and a feeding crank shaft 19 is movably connected to the other end of the connecting rod 18. A fixing rod 20 is fixedly connected to one side of the surface of the feeding crank shaft 19, and a torsion spring 21 is sleeved on the surface of the fixing rod 20, and a feeding tooth 22 is fixedly connected to the surface of the torsion spring 21; a feeding wheel 23 is movably connected inside the feeding crank shaft 19, and a lower feeding shaft 24 is fixedly connected to one side of the feeding wheel 23, and the lower feeding shaft 24 is arranged between the two groups of vertical plates 10, and a material holding plate 33 is fixedly connected between both sides of the inner wall of the bottom shell 1;.

[0030] The above scheme is adopted: through the design of the bearing 37, the connecting rod 18, the feed crank shaft 19, the fixed rod 20, the torsion spring 21, the feed tooth 22, the feed wheel 23 and the lower feed shaft 24, when the bearing 37 drives the connecting rod 18 to move, one end of the connecting rod 18 will move on the surface of the feed crank shaft 19. During the movement, because the torsion spring 21 will drive the feed tooth 22 to always contact the feed wheel 23, the feed tooth 22 will be driven to continuously push the feed wheel 23 and rotate the feed wheel 23, and the feed wheel 23 will drive the lower feed shaft 24 to rotate, thereby achieving the effect of facilitating automatic feeding.

[0031] refer to Figure 5 An upper feeding shaft 32 is commonly provided between the two groups of vertical plates 10, and both ends of the upper feeding shaft 32 are fixedly connected to movable plates 29, and one side of the surface of the two groups of movable plates 29 is fixedly connected to movable blocks 31, and the two groups of movable blocks 31 are movably connected to center rods 30, and the two groups of center rods 30 are fixedly connected to one side of the vertical plates 10; one end of the two groups of movable plates 29 is fixedly connected to the inside of the cylinders 27, and the surfaces of the two groups of rotating columns 28 are movably connected to the cylinders 27, and the other ends of the two groups of cylinders 27 are movably connected to the rotating rods 26, and the surfaces of the two groups of rotating rods 26 are fixedly connected to the mounting blocks 25, and the two groups of mounting blocks 25 are respectively fixedly connected to one side of the surface of the two groups of vertical plates 10.

[0032] The above scheme is adopted: through the design of the vertical plate 10, the upper feeding shaft 32, the movable plate 29, the movable block 31, the center rod 30, the rotating column 28, the cylinder 27, the rotating rod 26 and the mounting block 25, when the cylinder 27 is running, it will push the movable plate 29 to rotate on the surface of the center rod 30 using the movable block 31. During the pushing process, the cylinder 27 will use the rotating rod 26 and the rotating column 28 to rotate to prevent jamming, and will drive the upper feeding shaft 32 to be pressed downward, thereby achieving the effect of facilitating feeding and improving practicality.

[0033] The working principle of this utility model:

[0034] During use, when the motor 2 is running, the belt 3 will be used to drive the eccentric shaft 11 to rotate. During the rotation of the eccentric shaft 11, the push plate 12 will be driven to continuously press the fixed block 5 downward. At the same time, due to the support of the fixed plate 6 on the spring 7, the spring 7 drives the first nut 9 to reset upward through the elastic reaction force. The first nut 9 then drives the upper die seat 15 to reset upward continuously through the pull rod 8, thereby making the upper die seat 15 continuously move up and down. Before processing, the eccentric position of the rectangular block 36 inside the circular plate 35 is adjusted. After the position is determined, The bearing 37 is sleeved on the surface of the screw 34 and fixed by the second nut 17, so that the connecting rod 18 drives the feed crank shaft 19 to move. When the eccentric shaft 11 drives the upper and lower materials, it cooperates with the circular plate 35 to drive the eccentrically installed bearing 37, so that the bearing 37 drives the connecting rod 18 to move in a circular manner around the eccentric position. At this time, the connecting rod 18 drives the feed crank shaft 19 movably installed therewith to twist up and down the axis of the feed shaft 24 below. When the connecting rod 18 is pulled to the top position by the bearing 37, the feed crank shaft 19 twists upward around the lower feed shaft 24, and at the same time drives the fixed The fixed rod 20 cooperates with the feeding teeth 22 to squeeze and push the fitted feeding wheel 23 to make the lower feeding shaft 24 rotate with a ratchet, thereby realizing stable feeding of the synchronous eccentric shaft 11. At the same time, due to the torsion of the torsion spring 21, the rotating feeding wheel 23 is squeezed and fitted by the feeding teeth 22 to achieve anti-rotation and stable feeding. When the connecting rod 18 is driven by the bearing 37 to the bottom position, the feeding teeth 22 and the ratchet teeth of the feeding wheel 23 are in the same direction, so the feeding wheel 23 will not be driven to rotate with it. In addition, the torsion of the torsion spring 21 is used to ensure that the feeding crank shaft 19 is always driven during the rotation process. The movable fixed rod 20 cooperates with the feeding tooth 22 to fit the feeding wheel 23 to achieve anti-rotation, which makes it convenient for the connecting rod 18 to move upward again to drive the feeding crank shaft 19 to perform feeding operation, thereby realizing automatic and synchronous feeding. Before this, the cylinder 27 is started to push the movable plate 29 to rotate on the surface of the center rod 30 using the movable block 31. During the pushing process, the cylinder 27 will use the rotating rod 26 and the rotating column 28 to rotate to prevent jamming, and will drive the upper feeding shaft 32 to press down to make the metal plate and the top of the lower feeding shaft 24 precisely contact, which is convenient for feeding and thus improves practicality.

[0035] To sum up: this metal mesh punching machine, through the structure of punching pins 14, upper die base 15, lower die base 16, second nut 17, connecting rod 18, feed crank shaft 19, fixed rod 20, torsion spring 21, feed tooth 22, feed wheel 23, lower feed shaft 24, mounting block 25 and rotating rod 26, solves the problem that the traditional punching device has a relatively single function. When punching holes in the metal mesh, different machines need to be used to operate the metal mesh, which is time-consuming and labor-intensive, and the work efficiency is low. Therefore, the traditional device can no longer meet people's daily work needs.
