[0019] In addition, in the description of the present application, terms such as "first" and "second" are only used for differential description and should not be construed as indicating or implying relative importance.

[0020] As Figures 1 to 7 shown, it shows a screen punching machine for metal wire mesh production in an embodiment of the present disclosure, including a base 1 and a stamping part 2. The stamping part 2 is fixedly installed on the base 1, and a metal sheet or a metal plate passes through the stamping part 2. It further includes a fixed frame 3 and a stepping conveying device. The fixed frame 3 is fixedly installed on the base 1. Fixed frames 3 are arranged on both sides of the stamping part 2. There are four stepping conveying devices, and the four stepping conveying devices are fixedly arranged on the fixed frame 3. Two stepping conveying devices are respectively arranged on both sides of the stamping part 2. The two stepping conveying devices on the same side are respectively arranged on the upper and lower sides of the metal sheet. The stepping conveying device is used to convey the metal sheet. The stepping conveying device includes a C-shaped pressing plate mechanism and an I-shaped pressing plate mechanism. The I-shaped pressing plate mechanism is fixedly arranged in the center of the fixed frame 3, and the I-shaped pressing plate mechanism can contact the metal sheet. There are two C-shaped pressing plate mechanisms, and the two C-shaped pressing plate mechanisms are respectively fixedly connected to both sides of the fixed frame 3. The two C-shaped pressing plate mechanisms are arranged in pairs facing each other, and the C-shaped pressing plate mechanism can contact the metal sheet. The C-shaped pressing plate mechanism and the I-shaped pressing plate mechanism alternately contact the metal sheet. When conveying the metal sheet or the metal plate, the two stepping conveying devices located above and below the metal sheet on the same side are linked. The two C-shaped pressing plate mechanisms move simultaneously to press the metal sheet and drive the metal sheet to move. When the C-shaped pressing plate mechanism finishes conveying the metal sheet, the I-shaped pressing plate mechanism contacts the metal sheet and drives the metal sheet to move. Through the cyclic drive of the C-shaped pressing plate mechanism and the I-shaped pressing plate mechanism, the metal sheet can be driven to move. The two stepping conveying mechanisms on both sides of the stamping part 2 can drive and convey the metal sheet before stamping and the metal wire mesh after stamping. The conveying speed of the stepping conveying mechanism closer to the metal wire mesh is faster.

[0021] As Figures 2 to 5As shown in the figure, the I-shaped pressing plate mechanism includes a first driving cylinder 4, a first track assembly, and an I-shaped pressing plate 5. There are multiple first driving cylinders 4, and all of the multiple first driving cylinders 4 are fixedly installed on the fixed frame 3. There are multiple first track assemblies. The output end of the first driving cylinder 4 is fixedly connected to the first track assembly. An I-shaped pressing plate 5 is slidably connected to the first track assembly. The first track assembly is used to drive the I-shaped pressing plate 5 to slide. The center of the I-shaped pressing plate 5 is slidably connected to the side of the first track assembly close to the metal sheet. The I-shaped pressing plate 5 can contact the metal plate. The C-shaped pressing plate mechanism includes a second driving cylinder 6, a second track assembly, and a C-shaped pressing plate 7. There are multiple second driving cylinders 6, and all of the multiple second driving cylinders 6 are fixedly installed on the fixed frame 3. The second track assembly is fixedly connected to the output ends of the multiple second driving cylinders 6. A C-shaped pressing plate 7 is slidably connected to the second track assembly. The center of the C-shaped pressing plate 7 is slidably connected to the side of the second track assembly close to the metal sheet. The C-shaped pressing plate 7 can contact the metal plate. The I-shaped pressing plate 5 and the C-shaped pressing plate 7 have a large area and can press the metal sheet. At the same time, through the support plates 8 on the I-shaped pressing plate 5 and the C-shaped pressing plate 7, the contact area with the metal sheet can be extended, and the integrity when driving the metal sheet to move can be enhanced. The C-shaped pressing plates 7 on both the upper and lower sides of the metal sheet simultaneously press the metal sheet, and the movement of the C-shaped pressing plate 7 drives the metal sheet to move. At this time, the I-shaped pressing plate 5 separates from the metal sheet and moves in the direction opposite to the movement direction of the metal sheet. When the C-shaped pressing plate 7 moves to one end of the sliding track 15, the I-shaped pressing plate 5 contacts the metal sheet and drives the metal sheet to move, and the C-shaped pressing plate 7 separates from the metal sheet, thereby alternately driving the metal sheet to move.

[0022] As Figures 3 to 5 shown, the I-shaped pressing plate 5 is arranged between two C-shaped pressing plates 7. Support plates 8 are arranged on both sides of the I-shaped pressing plate 5 close to the two C-shaped pressing plates 7. Curled edges 9 are arranged on both sides of the I-shaped pressing plate 5 away from the C-shaped pressing plates 7. Support plates 8 are also arranged on the side of the C-shaped pressing plate 7 close to the I-shaped pressing plate 5. The support plates 8 on the I-shaped pressing plate 5 and the C-shaped pressing plate 7 are arranged in a staggered manner. Curled edges 9 are also arranged on both sides of the C-shaped pressing plate 7 away from the I-shaped pressing plate 5. The curled edges 9 can prevent the pressure at the edges of the I-shaped pressing plate 5 and the C-shaped pressing plate 7 from damaging the metal sheet when pressing the metal sheet. When the I-shaped pressing plate 5 and the C-shaped pressing plate 7 alternately contact the metal sheet, the support plates 8 on the C-shaped pressing plate 7 will extend between the support plates 8 on the I-shaped pressing plate 5 or separate between the support plates 8 on the I-shaped pressing plate 5. Through the staggered arrangement of the support plates 8, the overall control of the metal sheet can be ensured. The two C-shaped pressing plates 7 slide through simultaneously, pulling the metal sheet through the edge of the metal sheet, and the I-shaped pressing plate 5 pulls the metal sheet through the center of the metal sheet.

[0023] As Figures 4 to 6As shown, the track assemblies 1 and 2 have the same structure. The track assembly 1 includes a fixed bracket 1, a fixed bracket 2 and a sliding track 15. The fixed bracket 1 is fixedly connected to the output end of the driving cylinder 1 or the output end of the driving cylinder 2. A tension pulley 11 is rotatably connected to the fixed bracket 1. The fixed bracket 2 is fixedly connected to the output end of the driving cylinder 1 or the output end of the driving cylinder 2. A tension member 13 is fixedly connected to the fixed bracket 2. A tension pulley 14 is rotatably connected to the tension member 13. Both ends of the sliding track 15 are fixedly connected to the fixed bracket 1 and the fixed bracket 2. The sliding track 15 is slidably connected to the C-shaped pressing plate 7 or the I-shaped pressing plate 5. A spring is provided in the tension member 13 to push the tension pulley 14, so that the tension pulley 14 stretches the transmission cable 18. The transmission cable 18 on the track assembly 1 is fixedly connected to the counterweight 17 and the I-shaped pressing plate 5. The transmission cable 18 on the track assembly 2 is fixedly connected to the counterweight 17 and the C-shaped pressing plate 7. Taking the track assembly 1 as an example, when the output end of the driving cylinder 3 drives the I-shaped pressing plate 5 to slide, the counterweight 17 is pulled to slide through the transmission cable 18. When the I-shaped pressing plate 5 approaches the fixed bracket 1, the counterweight 17 approaches the fixed bracket 2. The center of gravity on the sliding track 15 can be adjusted by the counterweight 17 to prevent the sliding track 15 from tilting due to the sliding of the I-shaped pressing plate 5, which affects the driving cylinder 1 and the conveyance of the metal sheet.

[0024] As Figures 3 to 7 shown, a driving cylinder 3 is fixedly installed on the fixed bracket 1. The output end of the driving cylinder 3 is fixedly connected to the C-shaped pressing plate 7 or the I-shaped pressing plate 5. A counterweight 17 is slidably connected to the side of the sliding track 15 away from the metal sheet. A transmission cable 18 is tensioned and sleeved on the tension pulley 11 and the tension pulley 14. The counterweight 17 is fixedly connected to the transmission cable 18. The C-shaped pressing plate 7 and the I-shaped pressing plate 5 are respectively fixedly connected to the transmission cable 18. The output end of the driving cylinder 3 extends and contracts to pull the C-shaped pressing plate 7 or the I-shaped pressing plate 5 to slide. When the C-shaped pressing plate 7 or the I-shaped pressing plate 5 contacts the metal sheet, the metal sheet is pulled for conveyance. When the C-shaped pressing plate 7 or the I-shaped pressing plate 5 separates from the metal sheet, the output end of the driving cylinder 3 drives the C-shaped pressing plate 7 or the I-shaped pressing plate 5 to quickly move to the initial position for convenient re-conveyance.

[0025] As Figures 4 to 6 shown, support arms 19 are fixedly connected to both the fixed bracket 1 and the fixed bracket 2. The support arms 19 are slidably connected to the fixed frame 3 and are slidably connected to the inside of the fixed frame 3. When the C-shaped pressing plate 7 and the I-shaped pressing plate 5 drive the metal sheet to slide, the support arms 19 support the fixed frame 3 to prevent the driving cylinder 1 or the driving cylinder 2 from being laterally stressed.

[0026] In some examples, a metal sheet or plate is passed through the stamping part 2 and between the upper and lower two step conveyor devices. A total of four step conveyor devices are started simultaneously to convey the metal sheet. The output end of the first driving cylinder 4 extends to push the I-shaped pressing plate 5 into contact with the metal sheet. At this time, the output end of the third driving cylinder 16 connected to the I-shaped pressing plate 5 shortens to pull the I-shaped pressing plate 5 to slide on the sliding track 15. The upper and lower I-shaped pressing plates 5 of the metal sheet clamp and pull the metal sheet to slide. At this time, the output end of the second driving cylinder 6 remains in the shortened state, and the output end of the third driving cylinder 16 connected to the C-shaped pressing plate 7 extends to push the C-shaped pressing plate 7 to move in the opposite direction to the movement direction of the metal sheet. When the I-shaped pressing plate 5 approaches the first fixing frame 10, the output end of the second driving cylinder 6 extends to push the C-shaped pressing plate 7 into contact with the metal sheet. At this time, the C-shaped pressing plate 7 drives the metal sheet to move at the output end of the third driving cylinder 16, and the output end of the first driving cylinder 4 shortens to pull the I-shaped pressing plate 5 away from the metal sheet. When the I-shaped pressing plate 5 and the C-shaped pressing plate 7 slide, the counterweight 17 moves in the opposite direction accordingly to balance the sliding track 15.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered by the scope of the claims of the present disclosure.
