Description

Technical Field

[0001] The invention relates to the technical field of metal mesh stamping, and in particular to a metal mesh stamping device. Background Art

[0002] Metal stamping, stretching and forming machines are common in the field of hardware processing. They are used to process metal sheets to make them mesh or grid-like. The current metal mesh stamping and stretching forming machines mainly include a support frame and a model slot, followed by a motor and a stamping and forming table. Metal mesh is prone to burrs during stamping, and metal plates are prone to deformation during stamping, which affects the processing quality of the formed metal mesh. At the same time, the cut waste is often not collected in a centralized manner, which is not conducive to the recycling of waste. Therefore, we proposed a metal mesh stamping device. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a metal mesh punching device, comprising: A bottom plate, and a bracket symmetrically arranged on the top of the bottom plate; A punching mechanism, which is arranged on a side of the bracket away from the bottom plate and is used for punching holes on the surface of the metal plate to form a mesh; A conveying mechanism, which is symmetrically arranged on both sides of the punching mechanism and is used for smoothly conveying the metal mesh; The top of the bottom plate is fixedly connected to the bottom of the bracket, the sides of the two brackets away from the bottom plate are fixedly connected to the side of the stamping mechanism close to the bottom plate, and the bottom of the conveying mechanism is fixedly connected to the top of the bottom plate; Among them, the stamping mechanism includes: A punching plate, the surface of which has holes evenly distributed for the punched waste to fall off; A punching column, which is provided in plurality and is used for punching holes on the surface of the metal plate; A driving assembly having a lifting structure for driving the punching column to lift and lower for punching; The stamping plate is arranged at the interval between the two brackets, and the two sides of the stamping plate are fixedly connected to the sides of the two brackets close to each other, and the sides of the driving assembly close to the bottom plate are respectively fixedly connected to the sides of the two brackets away from the bottom plate, and the stamping column is fixedly connected to the side of the driving assembly close to the stamping plate, and the surface of the stamping column is slidably connected to the inner side surface of the stamping plate, and the metal plate is sequentially passed through a conveying mechanism, the interval between the stamping column and the stamping plate, and another conveying mechanism. The metal plate moves, driving the structures of the two conveying mechanisms to roll, ensuring the smooth conveying of the metal plate and avoiding bending of the metal plate during stamping, which affects the shape after stamping. The driving assembly is started, and the driving assembly drives the stamping column to approach the stamping plate. The stamping column first contacts the steel plate and then penetrates it. As the metal plate moves, the surface of the metal plate is continuously punched to complete the punching forming of the metal mesh plate, and finally the waste after stamping is carried into the other side of the stamping plate to avoid the waste remaining on the top of the stamping plate and affecting the continuous punching of the steel plate.

[0004] Furthermore, there are several stamping columns, which are evenly distributed on the side of the stamping plate away from the bottom plate. Several stamping columns can complete multiple punchings at one time, speed up the punching speed, and thus improve production efficiency. A positioning plate is provided at the interval between the driving assembly and the stamping plate. The inner side surface of the positioning plate is slidably connected to the surfaces of several stamping columns, and the side of the positioning plate close to the stamping plate is flush with the end of the stamping column close to the stamping plate. When punching, the positioning plate first contacts the steel plate and presses the steel plate to avoid bending or movement of the steel plate during punching, thereby achieving the purpose of pre-positioning. Then the stamping column continues to move to penetrate the steel plate.

[0005] Furthermore, a positioning spring is provided at the interval between the driving assembly and the positioning plate. The positioning spring is provided on the outer ring of the stamping column, and the two ends of the positioning spring are respectively fixedly connected to the side where the driving assembly and the positioning plate are close to each other. The stamping column passes through the positioning plate, and the positioning spring is compressed, thereby buffering the lifting and lowering of the driving assembly to achieve a shock-absorbing effect. At the same time, before the second punching, the driving positioning plate is reset to ensure that the positioning plate contacts the metal plate before stamping to ensure the pre-positioning effect.

[0006] Furthermore, a circular groove is provided at one end of the stamping column close to the stamping plate, and a slope is provided at one end of the stamping column close to the stamping plate. A tooth groove is also provided at one end of the stamping column close to the stamping plate. A plurality of tooth grooves are evenly provided along the circumference of the stamping column, and the tooth grooves are provided outside the circular groove, and a slope is provided at the bottom of the inner side surface of the tooth groove. The end of the stamping column close to the stamping plate forms two staggered serrated structures. When punching, the former serrated structure penetrates the metal plate, and a circular hole is punched out on the surface of the metal plate. There are several holes in the center of the hole. As the punching column penetrates further, another staggered serrated structure cuts off the remaining connections to form a circular hole. The waste under the punching forms a special-shaped waste with multiple bends instead of a circular plate. This can prevent the waste from sticking to the inside of the circular groove and facilitate the falling of the waste. The two staggered serrated structures divide the punching into two steps, which can reduce the difficulty of punching. At the same time, the two serrated structures are staggered to form a whole circular section, which can avoid the generation of burrs and ensure the quality of punching.

[0007] Furthermore, a top plate is slidably connected to the inner side surface of the circular groove, and an ejector spring is fixedly connected to the side of the top plate away from the stamping plate. One end of the ejector spring away from the top plate is fixedly connected to the side of the inner side surface of the circular groove close to the top plate. The waste material presses the top plate, and the top plate slides toward the inside of the circular groove and compresses the ejector spring. After the stamping is completed, the ejector spring quickly drives the top plate to reset and ejects the waste material, thereby preventing the waste material from being stuck in the circular groove and ensuring that the waste material falls at the bottom of the stamping plate.

[0008] Furthermore, a material discharge frame is provided on the side of the stamping plate away from the positioning plate, and the two sides of the material discharge frame are respectively fixedly connected to the sides of the two brackets close to each other, and the top of the inner side surface of the material discharge frame is inclined. The waste falls from the side of the stamping plate away from the positioning plate and enters the inside of the material discharge frame. Since the top of the inner side surface of the material discharge frame is inclined, the waste will fall along the inclined direction to complete the centralized collection of the waste, and the waste is pressed into a special-shaped structure with multiple bends instead of a circular plate shape, which can prevent the waste from being adsorbed inside the material discharge frame, and change its falling mode from sliding to rolling, thereby preventing the waste from being blocked inside the material discharge frame.

[0009] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0010] Furthermore, the conveying mechanism includes a conveying roller and a lifting assembly symmetrically arranged at both ends of the conveying roller, two of the conveying rollers are arranged at the interval between the two lifting assemblies, the inner walls of the conveying rollers are rotatably connected with a conveying shaft, the two ends of the conveying shaft close to the bottom plate are respectively rotatably connected to the sides of the two lifting assemblies close to each other, and the two ends of the conveying shaft away from the bottom plate are respectively slidably connected to the sides of the two lifting assemblies close to each other, the outer side of the conveying roller is fixedly connected with a film, and the film is arranged in a spiral shape, and a plurality of the films are evenly distributed along the circumference of the conveying roller, a metal plate is placed at the interval between the two conveying rollers, the lifting assembly drives the conveying roller away from the bottom plate to rise and fall, and squeezes and contacts the metal plate, and when the metal plate moves, the two conveying rollers are driven to rotate around the conveying shaft, thereby ensuring that the metal plate can move parallel to the bottom plate, ensuring stable conveying, and the two ends of the metal plate are squeezed by the conveying rollers, which can prevent the metal plate from bending when it contacts the positioning plate, and the spirally arranged film can increase the friction between the metal plate and the metal plate, thereby preventing the metal plate from slipping, and further ensuring the smooth conveying of the metal plate.

[0011] Furthermore, the lifting assembly includes an outer frame, the inner side surface of the outer frame is fixedly connected to a sleeve plate, the sleeve plate is fixedly connected to the top of the base plate, the two conveying shafts are fixedly connected to a connecting block at one end located inside the outer frame, a lifting telescopic rod is provided at the interval between the two connecting blocks, the two ends of the lifting telescopic rod are respectively fixedly connected to the side of the two connecting blocks close to each other, the surface of the conveying shaft close to the base plate is rotatably connected to the inner side surface of the sleeve plate, and the surface of the conveying shaft away from the base plate is limitedly slidably connected to the inner side surface of the sleeve plate, and the lifting telescopic rod is started to drive the connecting block away from the base plate to rise and fall, thereby driving the conveying shaft connected thereto to rise and fall, and driving the conveying roller away from the base plate to rise and fall, thereby pressing the metal plate to ensure its stable conveying, and when punching, further driving the conveying roller to press the metal plate to prevent it from bending during punching.

[0012] Furthermore, the inner side surface of the sleeve plate is fixedly connected to a limiting column, and the limiting column passes through the conveying shaft away from the bottom plate, the surface of the limiting column is slidably connected to the inner side surface of the conveying shaft away from the bottom plate, the surface of the limiting column is slidably connected to a buffer spring, and the buffer spring is arranged at the interval between the two conveying shafts, the conveying shaft away from the bottom plate is lifted and lowered, and slides on the surface of the limiting column, and at the same time compresses the buffer spring, the limiting column limits the lifting and lowering of the conveying shaft to avoid offset between the two conveying rollers, and the setting of the buffer spring can buffer the movement of the conveying roller.

[0013] The present invention has the beneficial effects: The present invention sets a stamping mechanism, and the stamping column first contacts the steel plate and then penetrates it, carrying the waste material after stamping into the other side of the stamping plate, so as to avoid the waste material remaining on the top of the stamping plate and affecting the continuous punching of the steel plate. Several stamping columns can complete multiple punchings at one time, speed up the punching speed, and thus improve the production efficiency. The positioning plate first contacts the steel plate and presses the steel plate to avoid bending or movement of the steel plate during punching, so as to achieve the purpose of pre-positioning.

[0014] The present invention arranges a punching column, and the front serrated structure penetrates the metal plate and punches a plurality of holes in the center of the circle on the surface of the metal plate. As the punching column further penetrates, another staggered serrated structure cuts off the remaining connection to finally form a circular hole. The waste material under the punching forms a special-shaped waste material with multiple bends rather than a circular plate shape, which can prevent the waste material from sticking to the inside of the circular groove and facilitate the falling of the waste material. The two staggered serrated structures divide the punching into two-step operation, which can reduce the difficulty of punching. At the same time, the two serrated structures are staggered to form a whole circular cross-section, which can avoid the generation of burrs and ensure the punching quality.

[0015] The present invention provides a material discharge frame with an inner top surface of the material discharge frame being inclined, so that waste materials fall along the inclined direction, thereby completing the centralized collection of waste materials. Moreover, the waste materials are pressed into a special-shaped structure with multiple bends rather than a circular plate shape, thereby preventing waste materials from being adsorbed inside the material discharge frame and changing the falling mode from the original sliding to rolling, thereby preventing waste materials from being blocked inside the material discharge frame.

[0016] The present invention sets a conveying mechanism to ensure that the metal plate can move parallel to the bottom plate and ensure stable conveying. The two ends of the metal plate are squeezed by the conveying rollers, which can prevent the metal plate from bending when contacting the positioning plate. The spirally arranged film can increase the friction between the metal plate and the metal plate to prevent the metal plate from slipping, further ensuring the smooth conveying of the metal plate. When punching, the conveying rollers are further driven to press the metal plate to prevent it from bending during punching. BRIEF DESCRIPTION OF THE DRAWINGS

The positioning spring 35 is provided on the outer ring of the stamping column 32, and the two ends of the positioning spring 35 are respectively fixedly connected to the side where the driving component 33 and the positioning plate 34 are close to each other. The stamping column 32 passes through the positioning plate 34, and the positioning spring 35 is compressed, thereby buffering the lifting and lowering of the driving component 33 and achieving a shock-absorbing effect. At the same time, before the second punching, the driving positioning plate 34 is reset to ensure that the positioning plate 34 contacts the metal plate before stamping to ensure the pre-positioning effect.

A plurality of tooth grooves 37 are evenly provided along the circumference of the stamping column 32, and the tooth grooves 37 are provided outside the circular groove 36. A slope is provided at the bottom of the inner side surface of the tooth groove 37. The end of the stamping column 32 close to the stamping plate 31 forms two staggered serrated structures. When punching, the former serrated structure penetrates the metal plate and punches holes on the surface of the metal plate. Several holes are pressed out of the center of the circle. As the punching column 32 penetrates further, another staggered serrated structure cuts off the remaining connection to finally form a circular hole. The waste material under the punching forms a special-shaped waste material with multiple bends rather than a circular plate shape, which can prevent the waste material from sticking to the inside of the circular groove 36 and facilitate the falling of the waste material. The two staggered serrated structures divide the punching into two steps, which can reduce the difficulty of punching.

The two sides of the material discharge frame 310 are respectively fixedly connected to the sides of the two brackets 2 that are close to each other, and the top of the inner side surface of the material discharge frame 310 is inclined. The waste falls from the side of the stamping plate 31 away from the positioning plate 34 and enters the inside of the material discharge frame 310. Since the top of the inner side surface of the material discharge frame 310 is inclined, the waste will fall along the inclined direction to complete the centralized collection of the waste. The waste is pressed into a special-shaped structure with multiple bends instead of a circular plate shape, which can prevent the waste from being adsorbed inside the material discharge frame 310, and change its falling mode from sliding to rolling, thereby preventing the waste from being blocked inside the material discharge frame 310.

[0027] Example 2, please refer to Figure 1-Figure 9The conveying mechanism 4 includes a conveying roller 41 and lifting components 42 symmetrically arranged at both ends of the conveying roller 41. Two conveying rollers 41 are arranged at the interval between the two lifting components 42. The inner wall of the conveying roller 41 is rotatably connected with a conveying shaft 44. The two ends of the conveying shaft 44 close to the bottom plate 1 are respectively rotatably connected to the side of the two lifting components 42 close to each other, and the two ends of the conveying shaft 44 away from the bottom plate 1 are respectively slidably connected to the side of the two lifting components 42 close to each other. The outer side of the conveying roller 41 is fixedly connected with a film 43, and the film 43 is arranged in a spiral shape. The film 43 is circumferentially connected to the conveying roller 41. There are several evenly distributed ones, and the metal plate is placed in the interval between the two conveying rollers 41. The lifting component 42 drives the conveying roller 41 away from the bottom plate 1 to rise and fall, and squeezes and contacts the metal plate. When the metal plate moves, it drives the two conveying rollers 41 to rotate around the conveying shaft 44, so as to ensure that the metal plate can move parallel to the bottom plate 1 and ensure stable transportation. The two ends of the metal plate are squeezed by the conveying rollers 41 to avoid bending of the metal plate when it contacts the positioning plate 34. The spirally arranged film 43 can increase the friction between the metal plate and avoid slipping of the metal plate, thereby further ensuring the smooth transportation of the metal plate.

The surface of the limiting column 423 is slidably connected to a buffer spring 424, and the buffer spring 424 is arranged at the interval between the two conveying shafts 44. The conveying shaft 44 away from the base plate 1 is lifted and lowered, and slides on the surface of the limiting column 423, while compressing the buffer spring 424. The limiting column 423 limits the lifting and lowering of the conveying shaft 44 to avoid offset between the two conveying rollers 41, and the setting of the buffer spring 424 can buffer the movement of the conveying roller 41.

[0030] When in use, place the metal plate at the interval between the two conveying rollers 41, and the lifting component 42 drives the conveying roller 41 away from the bottom plate 1 to rise and fall, and squeeze and contact the metal plate. When the metal plate moves, the two conveying rollers 41 are driven to rotate around the conveying shaft 44, and the driving telescopic rod 332 is started. The driving telescopic rod 332 drives the driving plate 331 to rise and fall, and drives the stamping column 32 to rise and fall to stamp the metal plate. At the same time, the sliding rod 333 and the limiting plate 334 are driven to rise and fall, and the stamping column 32 is driven to approach the stamping plate 31. The positioning plate 34 first contacts the steel plate and presses the steel plate, and then the stamping column 32 continues to move to penetrate the steel plate. When punching, the conveying roller 41 is driven to press the metal plate, and the previous serrated structure of the stamping column 32 penetrates the metal. The metal plate is a member of a group of plates. Several holes with the center of the circle are punched out on the surface of the metal plate. As the punching column 32 further penetrates, another staggered serrated structure cuts off the remaining connection and finally forms a circular hole. The waste material squeezes the top plate 38, and the top plate 38 slides into the circular groove 36 and compresses the ejection spring 39. After the punching is completed, the ejection spring 39 quickly drives the top plate 38 to reset and ejects the waste material. The waste material falls from the side of the punching plate 31 away from the positioning plate 34 and enters the blanking frame 310. Since the top of the inner side surface of the blanking frame 310 is inclined, the waste material will fall along the inclined direction to complete the centralized collection of the waste material. Then the conveying roller 41 loosens the metal plate. As the metal plate moves, the surface of the metal plate is continuously punched to complete the punching forming of the metal mesh plate.
