Description

Technical Field

[0001] The invention belongs to the technical field of building board production, and in particular relates to a punching device for building board production. Background Art

[0002] Building panels are flat rectangular building material panels made into standard sizes, including color steel tiles and iron sheets. In order to facilitate the wide application of color steel tiles and iron sheets in the construction industry, they need to be trimmed, stamped, and cut to form building components of different sizes.

[0003] At present, the Chinese invention with the publication number of CN117181899B discloses a sheet metal stamping device for mechanical production, including a bottom plate, the top of which is fixedly connected with a stamping base, and the four corners of the top of the bottom plate are symmetrically fixedly connected with four pneumatic telescopic columns. The invention forces the connecting teeth to drive the toggle teeth to rotate by the downward movement of the punch, thereby driving the two top rings to push upward through the punching hole, and can push the deformation generated when the punching sleeve is punched downward to ensure the flatness of the sheet metal. The punching sleeve slides up and down in the connecting hole, driving the pressure plates on both sides to move closer or farther from each other, thereby flattening the deformed sheet metal on the upper surface of the punching hole to ensure the stamping quality of the sheet metal. The debris remaining in the punching sleeve during the punching process is ejected by the ejector column and the pressure head, and falls into the collection box, which can prevent the debris from remaining and affecting the punching work again, and collect and reuse the debris.

[0004] The existing color steel tile building iron sheet needs to be punched into a flat iron sheet with a trapezoidal groove during the processing process, which can greatly improve the strength of the iron sheet and reduce the risk of bending deformation. However, the existing stamping device can only punch out a trapezoidal groove. In the actual installation process of the color steel tile iron sheet, it is necessary to drill holes on both sides of a single iron sheet to bolt multiple iron sheets together. The existing stamping cannot perform fixed-distance punching on both sides of the color steel tile as needed, so it is not convenient for the subsequent installation and connection of the color steel tile, and the practicality is low. At the same time, after the iron sheet is stretched from the reel, it is not convenient to move after pressing and forming because it is long. The existing stamping device generally cuts the iron sheet into a single piece and then presses it, rather than cutting it after pressing. This causes the size of the pressed iron sheet to be reduced and deformed, so the size becomes inappropriate. The common practice is to lengthen a distance during cutting to compensate for the reduction deformation of the iron sheet, which is relatively wasteful, and often there is a lot of waste under cutting. Summary of the invention

[0005] The purpose of the present invention is to provide a punching device for producing building panels, which has the advantage of being able to simultaneously perform fixed-distance punching at both ends when pressing and forming building iron sheets, thereby facilitating the subsequent rapid installation of building iron sheets. At the same time, the building iron sheets can be punched and cut at one time, thereby improving the processing efficiency of the building iron sheets and reducing the waste of raw materials.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a stamping device for producing building boards, comprising a protective shell, an arc-shaped protrusion bolted on one side of the outside of the protective shell, a motor bolted on one side of the arc-shaped protrusion, an output end of the motor fixedly connected to an output shaft, an end of the output shaft away from the motor fixedly connected to a pressure plate roller rotatably connected to the protective shell, a stamping ring fixedly sleeved on the surface of the pressure plate roller, a placement plate slidably connected to the inside of the protective shell, a stamping groove used in conjunction with the stamping ring is provided on the top of the placement plate, and a cutting mechanism and a stamping mechanism used in conjunction with the placement plate are respectively installed inside the protective shell and the pressure plate roller.

[0007] By adopting the above technical scheme, after pressing a trapezoidal groove into the building iron sheet through the punching ring and the punching groove, the punching rod can slide back and forth through the arc-shaped protrusion to penetrate the first hole and the second hole to continuously punch holes on both sides of the edge of the building iron sheet. It is convenient for the subsequent rapid installation of the building iron sheet and improves practicality. During the reciprocating sliding of the cutting blade back and forth inside the second linkage belt, the side gear is engaged at the top of the fixed rack. As a result, the large gear is engaged with the small gear and drives the cutting blade to rotate, so that it can cut the stamped building iron sheet, so that the building iron sheet can be stamped and cut in one step, which improves the processing efficiency of the building iron sheet and reduces the waste of raw materials.

[0008] The present invention is further configured as follows: the stamping mechanism includes a fixed shaft rotatably connected to the inside of the pressure plate roller, the end of the fixed shaft away from the motor is bolted to the inside of the protective shell, the surface of the fixed shaft is fixedly sleeved with a fixed disk, the surface of the fixed disk is slidably sleeved with an arc-shaped sleeve, the end of the arc-shaped sleeve away from the fixed disk is fixedly connected to a punching rod slidably connected to the pressure plate roller, the bottom of the fixed disk is fixedly connected to an arc-shaped protrusion slidably connected to the arc-shaped sleeve, the surface of the punching rod is sleeved with a reset spring, the surface of the pressure plate roller and the top of the placing plate are respectively provided with a first hole and a second hole slidably connected to the punching rod, both sides of the bottom of the protective shell are bolted with a lifting cylinder, and the output end of the lifting cylinder is fixedly connected to the bottom of the placing plate.

[0009] By adopting the above technical solution, the punching rod can penetrate the first hole and the second hole to continuously punch holes on both sides of the edge of the building iron sheet, which is convenient for the subsequent rapid installation of the building iron sheet and improves practicality.

[0010] The present invention is further configured as follows: the cutting mechanism includes a first bevel gear fixedly sleeved with the surface of the output shaft, the arc-shaped protrusion is rotatably connected to the inside of the arc-shaped protrusion, the bottom of the connecting rod is provided with a third bevel gear rotatably connected to the arc-shaped protrusion, the top and bottom of the connecting rod are fixedly connected to second bevel gears respectively meshing with the first bevel gear and the third bevel gear, both sides of the bottom of the inner cavity of the protective shell are rotatably connected to reciprocating screws, one end of the two reciprocating screws is fixedly sleeved with a first linkage belt, and the end of the third bevel gear away from the second bevel gear is fixedly connected to the reciprocating screw.

[0011] By adopting the above technical scheme, the stamped building iron sheet can be cut, so that the building iron sheet can be stamped and cut in one step, thereby improving the processing efficiency of the building iron sheet.

[0012] The present invention is further configured as follows: a threaded sleeve is threadedly sleeved on the surface of the reciprocating screw, a sliding bracket slidably connected to the protective shell is fixedly connected to the surface of the threaded sleeve, a support plate is fixedly connected to the top of the sliding bracket, a fixed rack is bolted to the inside of the protective shell, a first rotating rod and a second rotating rod are rotatably connected to the inside of the support plate respectively, an end of the first rotating rod away from the second rotating rod is fixedly sleeved with a side gear meshing with the fixed rack, ends of the first rotating rod and the second rotating rod close to each other are fixedly sleeved with a large gear and a small gear meshing with each other respectively, an end of the second rotating rod away from the first rotating rod is fixedly sleeved with a cutting blade, and a cutting groove slidably connected to the cutting blade is provided on the top of the placement plate.

[0013] By adopting the above technical solution, when the placement plate is driven to move upward by the lifting cylinder, the cutting blade can be retracted into the cutting groove when the placement plate is raised, so that when cutting is not needed, it will not affect the movement of the building iron sheet on the top of the placement plate. When the placement plate is lowered, the cutting blade can extend out of the cutting groove, thereby cutting the building iron sheet.

[0014] The present invention is further configured as follows: the two sides of the top of the placing plate are rotatably connected with the first roller and the second roller respectively, and both ends of the pressure plate roller are fixedly sleeved with the second linkage belt which is fixedly sleeved with one end of the first roller and the second roller respectively.

[0015] By adopting the above technical solution, it is convenient to use the second linkage belt to make the pressure plate roller synchronously drive the first roller and the second roller to rotate, thereby conveniently pushing the building iron sheet forward on the top of the placement plate for continuous stamping.

[0016] The present invention is further configured as follows: anti-slip sleeves are fixedly attached to the surfaces of the first roller and the second roller, and trimming blades are fixedly attached to both ends of the surface of the first roller.

[0017] By adopting the above technical solution, the friction between the first roller and the second roller is increased, thereby pushing the building iron sheet to slide forward. At the same time, the first roller can be used to drive the trimming blade to rotate, and the edges of the stamped building iron sheet can be neatly cut to ensure that the size of the building iron sheet is consistent.

[0018] The present invention is further configured as follows: universal wheels are bolted to the four corners of the bottom of the protective shell, and a locker is fixedly installed on one side of the universal wheel.

[0019] The above technical solution is adopted to facilitate the position movement of the punching device, and the universal wheel can be limited by the lock to fix the position.

[0020] The present invention is further configured as follows: both sides of the top of the placement plate are rotatably connected with balls, and one side of the outside of the protective shell is bolted with an observation window.

[0021] With the above technical solution, since the two ends of the building iron sheet will slide inward when the punching ring and the punching groove are used to press the building iron sheet, the provision of the ball bearing can reduce the friction of the sliding of the building iron sheet. At the same time, it does not affect the forward sliding of the building iron sheet, which is convenient for observation during the punching process of the building iron sheet.

[0022] The present invention is further configured as follows: a collecting box used in conjunction with the cutting blade is bolted to one side of the interior of the protective shell, and a slag discharge port connected to the collecting box is opened on one side of the exterior of the protective shell.

[0023] By adopting the above technical solution, the cut waste can be collected and stored together to facilitate subsequent processing.

[0024] The present invention is further configured as follows: a limiting clamp ring which is slidably connected to the arc-shaped sliding sleeve is fixedly sleeved on the surface of the fixing disk.

[0025] By adopting the above technical solution, the arc-shaped sliding sleeve is limited when sliding on the surface of the fixed disk, thereby preventing it from being separated from the fixed disk.

[0026] In summary, the present invention has the following beneficial effects: 1. After the stamping ring and the stamping groove are pressed into a trapezoidal groove on the building iron sheet, the punching rod is pressed and slid up and down through the arc-shaped protrusion, so that the punching rod can penetrate the first hole and the second hole to continuously punch holes on both sides of the edge of the building iron sheet. This facilitates the subsequent rapid installation of the building iron sheet and improves practicality; 2. When the cutting blade slides back and forth inside the second linkage belt, the side gear meshes with the top of the fixed rack. The large gear meshes with the small gear and drives the cutting blade to rotate, so that it can cut the stamped building iron sheet, so that the building iron sheet can be stamped and cut at one time, improving the processing efficiency of the building iron sheet and reducing the waste of raw materials.

After the building iron sheet is pressed into a trapezoidal groove by the punching ring 7 and the punching groove 8. At the same time, the punching rod 904 is squeezed and reciprocated up and down through the arc-shaped protrusion 908, so that the punching rod 904 can penetrate the first hole 905 and the second hole 906 to continuously punch holes on both sides of the edge of the building iron sheet. It is convenient for the subsequent rapid installation of the building iron sheet and improves practicality.

[0031] refer to Figure 2 , Figure 4 , Figure 5 , Figure 6 The punching mechanism 9 includes a fixed shaft 901 rotatably connected to the inside of the pressure plate roller 6, and the end of the fixed shaft 901 away from the motor 4 is bolted to the inside of the protective shell 1, and a fixed disk 902 is fixedly sleeved on the surface of the fixed shaft 901, and an arc sleeve 903 is slidably sleeved on the surface of the fixed disk 902. The end of the arc sleeve 903 away from the fixed disk 902 is fixedly connected to a punching rod 904 slidably connected to the pressure plate roller 6, and the bottom of the fixed disk 902 is fixedly connected to an arc protrusion 908 slidably connected to the arc sleeve 903. The surface of the punching rod 904 is sleeved with a reset spring 907, and the surface of the pressure plate roller 6 and the top of the placement plate 3 are respectively provided with a first hole 905 and a second hole 906 that are slidably connected to the punching rod 904. Both sides of the bottom of the protective shell 1 are bolted with a lifting cylinder 909, and the output end of the lifting cylinder 909 is fixedly connected to the bottom of the placement plate 3. The punching rod 904 can penetrate the first hole 905 and the second hole 906 to continuously punch holes on both sides of the edge of the building iron sheet, so as to facilitate the subsequent rapid installation of the building iron sheet and improve practicality.

[0032] refer to Figure 1 , Figure 2 , Figure 7The first roller 14 and the second roller 15 are rotatably connected to the two sides of the top of the placement plate 3, and the two ends of the pressing plate roller 6 are fixedly sleeved with the second linkage belt 13 which is respectively fixedly sleeved with one end of the first roller 14 and the second roller 15. The second linkage belt 13 is convenient for the pressing plate roller 6 to synchronously drive the first roller 14 and the second roller 15 to rotate, so as to facilitate the building iron sheet to move forward on the top of the placement plate 3 for continuous stamping.

[0033] refer to Figure 2 The surfaces of the first roller 14 and the second roller 15 are fixedly covered with anti-slip sleeves 16, and both ends of the surface of the first roller 14 are fixedly covered with trimming blades 17. The friction between the surfaces of the first roller 14 and the second roller 15 is increased, thereby pushing the building iron sheet to slide forward. At the same time, the first roller 14 can be used to drive the trimming blade 17 to rotate, and the edges of the stamped building iron sheet can be neatly cut to ensure that the size of the building iron sheet is consistent.

[0034] refer to Figure 5 , Figure 6 The surface of the fixed disk 902 is fixedly sleeved with a limiting snap ring 24 that is slidably connected to the arc-shaped sliding sleeve 903. The arc-shaped sliding sleeve 903 is limited to slide on the surface of the fixed disk 902, thereby preventing it from being separated from the fixed disk 902.

[0035] Brief description of the use process: First, the lifting cylinder 909 is turned on to push the placement plate 3 upward to slide, so that the building iron sheet placed on the top of the placement plate 3 is pressed and fixed between the pressure plate roller 6 and the placement plate 3. Then, the motor 4 is turned on to drive the pressure plate roller 6 to rotate, so that the punching ring 7 and the punching groove 8 can squeeze the building iron sheet, thereby pressing a trapezoidal groove on the building iron sheet. After that, the arc sleeve 903 is driven to slide on the surface of the fixed disk 902 during the rotation of the pressure plate roller 6. When the arc sleeve 903 slides to the arc convex block 908 at the bottom of the fixed disk 902, the arc convex block 908 can squeeze the arc sleeve 903 from the inside of the first hole 905 pushed by the punching rod 904, so that it penetrates the first hole 905 and the second hole 906 and then punches the edge of the building iron sheet. Since the arc-shaped protrusion 908 is arranged at the bottom, the punching rod 904 will punch out to punch holes only after the first hole 905 is driven to the bottom by the pressing plate roller 6 and fits with the building iron sheet. At the same time, when 605 slides to other positions, the arc-shaped protrusion 908 cannot squeeze the arc-shaped sliding sleeve 903, and then the arc-shaped sliding sleeve 903 can drive the punching rod 904 to reset and retract into the first hole 905 through the rebound force of the first hole 905, so that the building iron sheet can be punched continuously at a fixed distance during the pressing process.

[0036] Embodiment 2: refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 A punching device for producing building boards includes a protective shell 1, an arc-shaped protrusion 10 is bolted to one side of the outer side of the protective shell 1, a motor 4 is bolted to one side of the arc-shaped protrusion 10, an output end of the motor 4 is fixedly connected to an output shaft 5, an end of the output shaft 5 away from the motor 4 is fixedly connected to a platen roller 6 rotatably connected to the protective shell 1, a punching ring 7 is fixedly sleeved on the surface of the platen roller 6, a placement plate 3 is slidably connected to the inside of the protective shell 1, a punching groove 8 used in conjunction with the punching ring 7 is provided on the top of the placement plate 3, and a cutting mechanism 2 and a punching mechanism 9 used in conjunction with the placement plate 3 are respectively installed inside the protective shell 1 and the platen roller 6. During the reciprocating sliding of the cutting blade 11 back and forth inside the second linkage belt 13, the side gear 212 is used to mesh at the top of the fixed rack 210. Therefore, the large gear 213 is meshed with the small gear 215 to drive the cutting blade 11 to rotate, so that it can cut the stamped building iron sheet, so that the building iron sheet is stamped and cut at one time, and the processing efficiency of the building iron sheet is improved.

[0037] refer to Figure 2 , Figure 3 , Figure 7 The cutting mechanism 2 includes a first bevel gear 201 fixedly sleeved with the surface of the output shaft 5, a connecting rod 202 is rotatably connected inside the arc-shaped protrusion 10, a third bevel gear 204 rotatably connected with the arc-shaped protrusion 10 is provided at the bottom of the connecting rod 202, and a second bevel gear 203 meshing with the first bevel gear 201 and the third bevel gear 204 is fixedly connected to the top and bottom of the connecting rod 202, respectively, and reciprocating screws 205 are rotatably connected on both sides of the bottom of the inner cavity of the protective shell 1, and one end of the two reciprocating screws 205 is fixedly sleeved with a first linkage belt 206, and one end of the third bevel gear 204 away from the second bevel gear 203 is fixedly connected to the reciprocating screw 205. The stamped building iron sheet can be cut, so that the building iron sheet is stamped and cut at one time, and the processing efficiency of the building iron sheet is improved.

[0038] refer to Figure 2 , Figure 3 , Figure 8The surface of the reciprocating screw 205 is threadedly sleeved with a threaded sleeve 207, and the surface of the threaded sleeve 207 is fixedly connected with a sliding bracket 208 that is slidably connected to the protective shell 1, and the top of the sliding bracket 208 is fixedly connected with a support plate 209, and a fixed rack 210 is bolted inside the protective shell 1, and the inside of the support plate 209 is rotatably connected with a first rotating rod 211 and a second rotating rod 214, respectively, and the end of the first rotating rod 211 away from the second rotating rod 214 is fixedly sleeved with a side gear 212 that meshes with the fixed rack 210, and the ends of the first rotating rod 211 and the second rotating rod 214 that are close to each other are respectively fixedly sleeved with a large gear 213 and a small gear 215 that mesh with each other, and the end of the second rotating rod 214 away from the first rotating rod 211 is fixedly sleeved with a cutting blade 11, and a cutting groove 12 that is slidably connected to the cutting blade 11 is opened on the top of the placement plate 3. When the placement plate 3 is driven to move upward by the lifting cylinder 909, the cutting blade 11 can be retracted into the cutting groove 12 when the placement plate 3 is raised, so that when cutting is not needed, it will not affect the movement of the building iron sheet on the top of the placement plate 3. When the placement plate 3 is lowered, the cutting blade 11 can extend out of the cutting groove 12, thereby cutting the building iron sheet.

[0039] refer to Figure 1 , Figure 2 , Figure 3 The four corners of the bottom of the protective housing 1 are bolted with universal wheels 19, and a locker 20 is fixedly installed on one side of the universal wheel 19. It is convenient for the stamping device to move its position, and the locker 20 can be used to limit the universal wheel 19, so as to fix the position.

[0040] refer to Figure 1 , Figure 2 , both sides of the top of the placement plate 3 are rotatably connected with ball bearings 18, and one side of the outside of the protective shell 1 is bolted with an observation window 21. Since the two ends of the building iron sheet will slide inward when the punching ring 7 and the punching groove 8 are pressing the building iron sheet, the provision of the ball bearings 18 can reduce the friction of the sliding of the building iron sheet. At the same time, it does not affect the forward sliding of the building iron sheet, which is convenient for observation during the punching process of the building iron sheet.

[0041] refer to Figure 1 , Figure 2 , Figure 3 A collecting box 22 used in conjunction with the cutting blade 11 is bolted to one side of the inner side of the protective shell 1, and a slag discharge port 23 connected to the collecting box 22 is provided on one side of the outer side of the protective shell 1. The cut waste can be collected and stored for subsequent processing.

[0042] Brief description of the use process: By turning on the lifting cylinder 909, the placement plate 3 is driven to slide downward. At this time, the pressure plate roller 6 and the placement plate 3 cannot squeeze the building iron sheet, and the building iron sheet is separated from the pressure plate roller 6. Turning on the motor 4 again will only drive the pressure plate roller 6 to idle, and the pressure plate roller 6 cannot drive the building iron sheet to slide forward. Then, the output shaft 5 drives the first bevel gear 201 to mesh with the second bevel gear 203 and then drives the third bevel gear 204 to rotate, so that the two reciprocating screws 205 rotate synchronously after being linked by the first linkage belt 206. After that, the reciprocating screw 205 is threadedly engaged with the threaded sleeve 207, so that the sliding bracket 208 slides back and forth inside the protective shell 1, so that the side gear 212 can mesh with the fixed rack 210 and drive the first rotating rod 211 to rotate inside the support plate 209. Then, the large gear 213 and the small gear 215 are meshed, so that the second rotating rod 214 drives the cutting blade 11 to rotate synchronously during the reciprocating sliding process inside the cutting groove 12, thereby cutting the building iron sheet. At the same time, since the cutting blade 11 is meshed with the large gear 213 and then the small gear 215, the rotation speed of the cutting blade 11 can be increased, thereby ensuring that the cutting blade 11 can cut the building iron sheet. And when the lifting cylinder 909 drives the placement plate 3 to move upward, when the placement plate 3 is raised, the cutting blade 11 can be retracted into the inside of the cutting groove 12, so that when cutting is not needed, it does not affect the movement of the building iron sheet on the top of the placement plate 3, and when the placement plate 3 is lowered, the cutting blade 11 can extend out of the inside of the cutting groove 12, thereby cutting the building iron sheet.
