Description

Technical Field

[0001] The invention relates to the technical field of sheet metal processing, in particular to a mechatronic sheet metal punching machine. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts, and sheet metal parts are indispensable in our lives. Sheet metal parts are made by filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending, die forging, water jet cutting, and precision welding.

[0003] The commonly used method of punching holes in sheet metal parts is to use a high-pressure punching machine to punch holes in the sheet metal parts, punching out the required holes one by one. Due to the thin thickness of the sheet metal parts, the sheet metal parts are prone to local deformation during the punching process. At the same time, the sheet metal parts may be stuck in the punching device after punching, which may easily cause damage to the punching device. Summary of the invention

[0004] To achieve the above object, the present invention is implemented through the following technical solution: a mechatronic sheet metal punching machine, comprising a platform (1), a waste box (5) is arranged inside the platform (1), a vertical plate (3) is fixedly connected to the outside of the platform (1), and a support arm is arranged at one end of the vertical plate (3) close to the platform (1), and further comprising: The punching assembly 4 comprises a hydraulic cylinder (41) fixedly mounted on the support arm, wherein the output end of the hydraulic cylinder is fixedly connected to a fixing plate, a punch is fixedly connected to a side of the fixing plate away from the hydraulic cylinder, a sleeve is slidably connected to the outside of the punch, and a pressure plate is fixedly connected to the outside of the sleeve; Preferably, the fixing assembly 2 includes a supporting member 21 fixedly installed in the middle of the top of the platform 1, and a slide groove is opened on the outer side of the supporting member. There are multiple slide grooves, and the multiple slide grooves are symmetrically arranged on the supporting member. The inner wall of the slide groove is slidably connected with a slider. When working, the material is placed on the supporting plate. At this time, the slider drives the connecting plate to move toward the middle of the supporting plate, so that the outer side of the material contacts the roller, and then clamps the two ends of the sheet metal. Then the hydraulic cylinder drives the fixed plate to move downward, so that the fixed plate drives the pressure plate to move downward, and the pressure plate contacts the top of the circular plate. The circular plate is squeezed and drives the round rod to move downward. At this time, the splint fixes the sheet metal up and down, and through multiple splints, the material at the punching position is fixed in multiple directions to avoid the punching process. The sheet metal is offset, which enhances the fixing effect of the equipment and improves the quality of the products produced by the equipment. The top of the slider is fixedly connected to a connecting plate, and the connecting plate is set to an L-shaped plate. The outer side of the connecting plate is slidably connected to a round rod, and the top of the round rod is fixedly connected to a round plate. The side of the round plate close to the round rod is fixedly connected to a limiting spring, and the end of the limiting spring away from the round plate is fixedly connected to the top of the connecting plate. The round rod penetrates the connecting plate, and the end of the round rod away from the round plate is fixedly connected to a splint. By setting the splint to a fan shape, the contact area between the splint and the sheet metal is increased. When the clamping force is constant, the larger the contact area, the smaller the pressure per unit area, thereby reducing the possibility of local deformation or damage to the clamped sheet metal. The splint is set to a fan shape.

[0005] Preferably, the clamping plate is slidably connected to the connecting plate, and the connecting plate is rotatably connected to a roller on one side away from the round rod, and the roller is made of rubber. During the movement of the material, the roller is set to utilize rolling instead of sliding, thereby reducing the friction between the edge of the material and the connecting plate, thereby reducing the loss caused by the punching process of the material. At the same time, due to the thin thickness of the sheet metal, the roller contacts the edge of the sheet metal, and utilizes the material and characteristics of rubber to adapt to sheet metals of different shapes and sizes, providing a more uniform clamping force, thereby reducing damage and deformation to the surface of the sheet metal. Its soft characteristics can also play a certain buffering role in the clamping process, reducing the risk of structural damage to the sheet metal caused by excessive clamping force. In addition, rubber material usually has a good friction coefficient, which can increase the friction between the sheet metal and the sheet metal, and improve the stability and reliability of clamping. The clamping plate is provided with a semicircular groove, the roller is located inside the semicircular groove of the clamping plate, and a moving component is provided in the middle of the support.

The end of the sleeve away from the fixing plate is fixedly connected with a connecting rod, and the end of the connecting rod away from the sleeve is fixedly connected with a fixing ring. During operation, the pressure plate contacts and squeezes the circular plate, so that the splint fixes the sheet metal part, and at the same time, the fixing ring contacts the upper surface of the sheet metal part. The hydraulic cylinder continues to move downward, and the compression spring is compressed by force, so that the sleeve drives the pressure plate to slide relatively on the outer wall of the punch, and then the hydraulic cylinder drives the punch to punch the sheet metal part. By setting the fixing ring, the sheet metal part around the punching place is fixed, and the punching place is supported to a certain extent, so that the sheet metal part can resist deformation when punching. At the same time, by setting the compression spring , plays a certain buffering role, avoids the pressure applied by the punch being too large, exceeding the bearing capacity of the sheet metal, causing deformation of the sheet metal, the sleeve is fixedly connected with a compression spring at one end away from the connecting rod, the compression spring is fixedly connected to the fixed plate at one end away from the sleeve, the punch passes through the sleeve, the connecting rod is fixedly connected with a limiting rod at one end close to the punch, and the limiting rod contacts with the punch at one end away from the connecting rod. After the punching is completed, the hydraulic cylinder drives the punch to leave the sheet metal, and the limiting rod slides on the outer surface of the punch, thereby preventing the waste of the sheet metal from sticking to the bottom of the punch. The outer wall of the pressing plate is slidably connected with a straight rod. When fixed, the hydraulic cylinder drives the pressing plate to continue to move downward, so that the straight rod slides inside the pressing plate, and the end of the straight rod away from the pressing plate is rotatably connected to the fixed plate, and a magnetic plate is fixedly connected at the outer edge of the pressing plate.

[0008] Preferably, the moving assembly includes a square plate, the square plate is located inside the limiting groove, a through hole is opened on the outer side of the square plate, the inner wall of the through hole is rotatably connected to a rotating rod, when working, the hydraulic cylinder drives the fixed plate to move downward, so that the fixed plate drives the pressure plate to move downward, the magnetism between the magnetic block and the magnetic plate is opposite, the pressure plate drives the magnetic plate close to the magnetic block, and under the action of the mutual attraction between the magnetic plate and the magnetic block, the magnetic block drives the square plate to move in the direction of the reset spring, so that the reset spring is compressed and deformed by force, so that the round hole and the punch are located in the same straight line, At the same time, the square plate drives the limit block to move. At this time, the rotating wheel and the sheet metal rotate relatively, and the sheet metal does not move with the limit block. When the positioning plate contacts the cylinder under the annular groove, the positioning plate drives the limit block to flip 180 degrees. At this time, the rectangular block contacts the lower surface of the sheet metal, so that the sheet metal does not deviate during operation. The rotating rod passes through the square plate, and the outer side of the rotating rod is fixedly connected to the limit block. The limit block is located inside the through hole. A rotating wheel is provided on the top of the limit block, and the bottom of the limit block is set as a rectangular block. A circular hole is opened on the outer side of the square plate. There are two through holes, which are symmetrically arranged with the circular hole as the center. A cleaning brush is fixedly connected to the bottom of the square plate. Waste materials after punching may remain in the limiting groove. The square plate drives the cleaning brush to move back and forth during work, thereby cleaning the inside of the limiting groove, so that the waste materials can enter the through opening and fall into the waste box, which is convenient for collecting waste materials. A magnetic block is fixedly connected to the outer side of the square plate, and a reset spring is fixedly connected to one end of the square plate away from the magnetic block. After the punching is completed, the magnetic plate is away from the magnetic block, and under the action of the elastic force of the reset spring, The square plate is reset, and friction is generated between the rectangular block and the sheet metal.

At the same time, a compression spring is set to play a certain buffering role to avoid excessive pressure applied by the punch, which exceeds the bearing capacity of the sheet metal and causes deformation of the sheet metal.
