Description

Technical Field

[0001] This utility model relates to the technical field of punching devices, specifically a spring-positioning punching device. Background Technology

[0002] Blanking is a stamping method that separates parts or blanks of the required shape and size from sheet metal. Blanking uses the cutting edge of a die to shear and separate the sheet metal along a certain contour line. In addition to being used as raw material preparation, blanking is often used to directly process washers, bicycle sprockets, instrument gears, cams, shift forks, instrument panels, as well as silicon steel sheets in motors and electrical appliances, and connectors in integrated circuits. Blanking accounts for the largest proportion of stamping production. During the blanking process, except for the metal near the shear contour line, the sheet metal itself does not undergo plastic deformation, so the parts processed by blanking from a flat plate are still planar in shape.

[0003] The published patent document with announcement number CN215702091U discloses a punching device for paper cup production. This published patent document uses a cardboard positioning mechanism to quickly press the top two sides of the cardboard, preventing the cardboard from shifting during punching and improving punching quality. It also uses a discharge mechanism to automatically discharge the punched cup bottoms into the hollow base, making material unloading convenient and highly automated. However, the published patent document requires additional driving force to fix the board material when positioning it, resulting in high operating costs. Utility Model Content

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-2 This utility model provides a spring-feeder positioning punching device: including a punching table 1, a bracket 2 fixedly installed on the top of the punching table 1, and a mold 3 set in the middle of the top of the punching table 1. An installation plate 4 is set inside the bracket 2, and a hydraulic cylinder 6 is fixedly installed on the top of the bracket 2. The output end of the hydraulic cylinder 6 is fixedly installed on the top of the installation plate 4. A die 5 matching the mold 3 is set below the installation plate 4, and positioning components 7 are set on the front and rear parts of both sides of the installation plate 4. The positioning components 7 include a U-shaped part 71 and a vertical shaft 72. The U-shaped part 71 is welded to the side of the installation plate 4, and the vertical shaft 72 passes through the U-shaped part 71 and is slidably connected to the U-shaped part 71. A ring 74 is fixedly connected to the vertical shaft 72, and a spring 75 is sleeved on the vertical shaft 72. The upper and lower ends of the spring 75 are fixedly connected to the top inner wall of the U-shaped part 71 and the top of the ring 74, respectively. A spring 73 is fixedly installed at the lower end of the vertical shaft 72.

[0022] In this technical solution, the hydraulic cylinder 6 drives the mounting plate 4 and the die 5 to move downwards, performing a punching operation on the material at the die 3. During the punching process, the spring sheet 73 first holds the material, which not only positions the material and ensures the accuracy of the punching, but also reduces the compressive force on the material through the elasticity of the spring sheet 73 itself. Furthermore, as the die 5 moves downwards, the vertical shaft 72 compresses the spring 75 through the ring 74, and the material can be fixed and positioned using the power of the punching, without the need for additional driving force for material positioning, thus reducing the cost of use.

[0023] In some technical solutions, such as Figure 1-3 As shown, four positioning tubes 22 are fixedly connected to the top of the punching table 1. Positioning shafts 23 matching the positioning tubes 22 are fixedly installed on both sides of the front and rear parts of the mold 3. The lower end of the positioning shaft 23 is inside the positioning tube 22. Threaded shaft 19 is fixedly connected to the four corners of the bottom of the mounting plate 4. Threaded shaft 20 is fixedly connected to the four corners of the top of the die 5. Matching nuts 21 are fitted on the threaded shaft 19 and the threaded shaft 20.

[0024] In use, the mold 3 can be installed by inserting each positioning shaft 23 into the corresponding positioning tube 22. The die 5 can be installed by aligning each threaded shaft 19 with the threaded shaft 20 and then screwing the nut 21 between the threaded shaft 19 and the threaded shaft 20. This increases the convenience of replacing the mold 3 and the die 5 and makes it more flexible to use.

[0025] In some technical solutions, such as Figure 1 and Figure 4 As shown, a bracket 2 8 is fixedly installed on one side of the top of the blanking table 1. An active roller 10 rotates inside the bracket 2 8, and a servo motor 1 9 is fixedly installed on the front side of the bracket 2 8. The output end of the servo motor 1 9 is fixedly installed to the front end of the active roller 10. Sliding holes 11 are opened on both the front and rear sides of the bracket 2 8, and a servo motor 2 12 is fixedly installed on the top of the bracket 2 8. A slider 13 is slidably connected inside the sliding hole 11, and a lead screw 24 is rotatably connected inside one of the sliding holes 11. A driven roller 14 is rotatably installed between two sliders 13. The lead screw 24 passes through one slider 13, and the upper end of the lead screw 24 is fixedly installed to the output end of the servo motor 2 12. The slider 13 is threadedly connected to the lead screw 24.

[0026] In use, the servo motor 12 drives the lead screw 24 to rotate, and the lead screw 24 drives the slider 13 to move downward, so that the driven roller 14 and the driving roller 10 clamp the end of the material. Then, the servo motor 9 drives the driving roller 10 to rotate, which can drive the material to move so that the material can reach the punching position at all positions.

[0027] In some technical solutions, such as Figure 1As shown, a through hole 16 is provided in the middle of the top of the punching table 1, and a discharge hole 17 is provided in the horizontal direction of the punching table 1. The through hole 16 is located below the mold 3, and the through hole 16 is connected to the discharge hole 17.

[0028] When in use, the parts punched on the mold 3 enter the unloading hole 17 through the through hole 16, which facilitates unloading and collection of the parts.

[0029] In some technical solutions, such as Figure 1 As shown, several feeding rollers 15 are equidistantly mounted on the top of the blanking table 1.

[0030] During use, the feeding roller 15 ensures that the blanking material can enter the blanking area smoothly.

[0031] In some technical solutions, such as Figure 1 As shown, casters 18 are fixedly installed at the four corners of the bottom of the blanking table 1.

[0032] The punching device is easy to move during use.

[0033] Working principle: Insert each positioning shaft 23 into the corresponding positioning tube 22 to complete the installation of mold 3. Align each threaded shaft 19 with threaded shaft 20, and then screw the nut 21 between threaded shaft 19 and threaded shaft 20 to complete the installation of die 5, increasing the convenience of changing mold 3 and die 5. Place the end of the material between the driving roller 10 and the driven roller 14. Servo motor 212 drives the lead screw 24 to rotate, and the lead screw 24 drives the slider 13 to move downward, so that the driven roller 14 and the driving roller 10 clamp the end of the material. Then, the servo motor 19 drives the material to move downward. The rotation of the drive roller 10 drives the material to move, so that the material can reach the punching position at all positions. The hydraulic cylinder 6 drives the mounting plate 4 and the die 5 to move downward to punch the material at the die 3. During the punching process, the spring sheet 73 first holds the material, which can not only position the material and ensure the accuracy of punching, but also reduce the extrusion force on the material through the elasticity of the spring sheet 73 itself. During the downward movement of the die 5, the vertical shaft 72 compresses the spring 75 through the ring 74. The material can be fixed and positioned by the punching power without the need for additional driving force for material positioning.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
