Technical Field

[0001] This utility model relates to the field of workpiece processing, specifically a metal punching device. Background Technology

[0002] Punching is a common metalworking process that involves creating holes in sheet metal or other materials.

[0003] In the existing technology, the workpiece punching device mainly consists of a hydraulic cylinder, a top seat connected to a punch, and a base. The hydraulic cylinder is used to control the top seat and the punch to move up and down, and then the punch moves down to punch out the corresponding hole in the workpiece, thereby completing the workpiece punching process.

[0004] However, during processing, after the workpiece is punched, the worker needs to remove the workpiece from the equipment to unload it, which is inconvenient, time-consuming and labor-intensive. Therefore, a metal punching device is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a metal punching device includes a worktable 11, a frame 12 fixedly connected to the top of the worktable 11, a hydraulic cylinder 13 fixedly connected to the top of the frame 12, a top seat 14 fixedly connected to the output end of the hydraulic cylinder 13, and a punch fixedly connected to the bottom of the top seat 14; a bracket 15 fixedly connected to the top of the worktable 11, a rotating shaft rotatably connected to the top of the bracket 15, a motor 17 fixedly connected to the side of the bracket 15, the output end of the motor 17 fixedly connected to the rotating shaft, a tilting seat 16 fixedly connected to the rotating shaft, a base 18 fixedly connected to the top of the tilting seat 16, and a punching hole opened at the corresponding position of the punch on the base 18; an electric push rod 21 fixedly connected to the side of the tilting seat 16, a fixed seat 22 fixedly connected to the output end of the electric push rod 21, and the fixed seat 22 located on the top of the tilting seat 16;

[0024] In use, the workpiece is placed on the base 18, and then the hydraulic cylinder 13 drives the top seat 14 to move down. The downward movement of the top seat 14 drives the punch to punch holes, thus completing the punching process of the workpiece. After punching, the motor 17 drives the flipping seat 16 to rotate 90 degrees, and then the workpiece falls off the base 18, thus completing the unloading of the workpiece. This makes it convenient for workers to use and reduces their workload. The motor 17 is a servo geared motor.

[0025] Before punching, the electric actuator 21 drives the fixed seat 22 to press down, and the fixed seat 22 comes down to fix the workpiece on the base 18. This can fix the workpiece and reduce the movement of the workpiece during the punching process.

[0026] Furthermore, such as Figure 3-5As shown, a vertical cylinder 31 is fitted onto the surface of the punch. A sliding hole 32 is formed at the corresponding position of the top seat 14 and the vertical cylinder 31. The top end of the vertical cylinder 31 is inserted into the sliding hole 32 and slidably connected thereto. A spring 33 is fixed between the top end of the vertical cylinder 31 and the inner wall of the sliding hole 32. Guide rods 43 are fixedly connected to both sides of the flip seat 16. Positioning seats 41 are fixedly connected to both ends of the top seat 14 at the corresponding positions of the guide rods 43. Positioning holes 42 are formed inside the positioning seats 41 at the corresponding positions of the guide rods 43.

[0027] In use, a vertical cylinder 31 is fitted onto the surface of the punch. The bottom end of the vertical cylinder 31 presses against the surface of the punching area of ​​the workpiece, which facilitates fixation. For thinner workpieces, it presses against the edge of the punching area, thus reducing deformation of the edge of the punching area and facilitating processing. A spring 33 is used to support the vertical cylinder 31 to press against the workpiece. Positioning seats 41 are installed on both sides of the top seat 14. After the top seat 14 is lowered, the guide rod 43 of its flip seat 16 is inserted into the positioning hole 42 in the positioning seat 41, which can play a guiding and positioning role.

[0028] Furthermore, such as Figure 3-5 As shown, a chip removal seat 5 is fixedly connected to the bottom of the bracket 15. The chip removal seat 5 is located at the bottom of the flipping seat 16, and the bottom of the chip removal seat 5 is inclined. A support 61 is fixedly connected to the chip removal seat 5. The support 61 and the flipping seat 16 are rotatably connected. A through hole 63 is opened on the base 18. A top rod 62 is slidably connected inside the through hole 63. The bottom end of the top rod 62 is in contact with and slidably engaged with the surface of the support 61.

[0029] During use, the chip removal seat 5 is provided to facilitate the discharge of waste chips from the punch, making it convenient for workers to use. The bottom end of the push rod 62 slides on the surface of the support 61. The support 61 has a protrusion. When the flipping seat 16 is flipped and tilted, the protrusion on the support 61 can help push the support rod out, thereby facilitating the ejection of the workpiece from the base 18 and making it easier to unload the workpiece.

[0030] Furthermore, such as Figure 3-5 As shown, a notch 7 is provided at the bottom of the positioning seat 41 and at the corresponding position of the guide rod 43. The notch 7 is located on the side of the positioning hole 42. In use, the notch 7 is used to allow the end of the guide rod 43 to pass through the notch 7 and enter the positioning seat 41 after the flip seat 16 is reset, so that the guide rod 43 can enter the positioning hole 42 for guidance.

[0031] Working principle: When in use, the workpiece is placed above the base 18, and then the hydraulic cylinder 13 drives the top seat 14 to move down. The downward movement of the top seat 14 drives the punch to punch holes, thereby completing the punching process of the workpiece. After punching is completed, the motor 17 drives the flipping seat 16 to rotate 90 degrees, and then the workpiece falls off the base 18, thereby completing the unloading of the workpiece. This makes it convenient for workers to use and reduces their workload. The motor 17 is a servo geared motor.

[0032] Before punching, the electric actuator 21 drives the fixed seat 22 to press down, and the fixed seat 22 fixes the workpiece on the base 18, thus fixing the workpiece and reducing its movement during punching. In use, a vertical cylinder 31 is fitted onto the surface of the punch, and the bottom end of the vertical cylinder 31 presses against the surface of the workpiece's punching area, facilitating fixation. For thinner workpieces, it presses against the edge of the punching area, reducing deformation and facilitating processing. A spring 33 supports the vertical cylinder 31 in pressing the workpiece, relying on the top seat 14... Positioning seats 41 are installed on both sides. After the top seat 14 is placed under the top seat 14, the guide rod 43 of the flip seat 16 is inserted into the positioning hole 42 in the positioning seat 41, which can play a guiding and positioning role. During use, the chip removal seat 5 is set to facilitate the discharge of waste chips from the punch, making it convenient for workers to use. The bottom end of the top rod 62 slides on the surface of the support 61. The support 61 is provided with a protrusion. When the flip seat 16 is flipped and tilted, the protrusion on the support 61 can cooperate to push out the support rod, thereby facilitating the ejection of the workpiece from the base 18, which can facilitate the unloading of the workpiece.
