Description

Technical Field

[0001] This utility model belongs to the field of punching die technology, specifically relating to a die with automatic burr removal function. Background Technology

[0002] Square tube punching dies are used to machine holes in square tubes, playing a vital role in the metal stamping industry. They are widely used in various fields such as construction, automotive, and furniture. In construction, they are primarily used for the precision machining of steel structural frames and supporting structures. In automotive production, they are frequently used for drilling holes in the body frame and chassis, playing a crucial role in improving vehicle rigidity and lightweight design. In furniture manufacturing, precise holes are needed for components such as chair armrests or bed frame connections to ensure stability during assembly.

[0003] The principle of square tube punching dies is mainly based on stamping technology. Sufficient pressure is applied to the square tube material through a punch, causing localized plastic deformation and ultimately forming a hole. Hydraulically driven square tube punching dies are used by a motor-driven oil pump that delivers hydraulic oil to the stamping cylinder. The piston rod of the cylinder moves up and down under pressure, moving the die connected to the piston rod. The hydraulic press controls the punching pressure by adjusting the oil pressure, featuring high punching force and high precision.

[0004] In practical applications, especially during punching operations, existing square tube punching dies often encounter a tricky problem: after the punching process, burrs easily form at the edges of the resulting round holes. These burrs come in various shapes, some being fine serrations, others irregular flanging. They abruptly adhere to the edges of the round holes, severely affecting the appearance quality of the punched square tubes, making them look less smooth and refined, and reducing the overall aesthetic appeal of the product.

[0005] More importantly, these rough edges pose significant safety hazards and numerous inconveniences during the subsequent use of the square tubes. Because the rough edges are quite sharp, they can easily come into direct contact with the skin when operators handle, install, or use the perforated square tubes, causing scratches. Utility Model Content

[0006] The purpose of this utility model is to provide a mold with an automatic burr removal function, which aims to solve the problem that existing square tube punching molds are prone to producing burrs at the edges of the round holes after the punching process. These burrs not only seriously affect the appearance quality of the square tube after punching, but also, because the burrs are relatively sharp, they can easily come into contact with the skin and cause scratches when operators handle, install or use the punched square tube.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mold with automatic burr removal function, comprising a mold body, a processing table, and a stamping base. The processing table is connected to the surface of the mold body, the stamping base is installed on the inner wall of the mold body, a bracket is installed on the side surface of the mold body, a square tube liner is connected between the bracket and the mold body, a limiting seat is connected to the surface of the processing table, a support plate is connected to the surface of the processing table, a movable frame is provided on one side of the support plate, a sliding groove is opened on the surface of the movable frame, a T-shaped slider is connected to the side surface of the support plate, a hydraulic rod is connected to the lower surface of the movable frame installed on the processing table, a drive motor is installed on the surface of the movable frame, and a grinding wheel is connected to the output end of the drive motor.

[0008] In a preferred embodiment of the present invention, a mold with an automatic burr removal function is provided, wherein the slide groove and the T-shaped slider are symmetrically arranged on both sides of the movable frame, and the movable frame is slidably connected to the slide groove and the T-shaped slider.

[0009] As a preferred embodiment of the mold with automatic burr removal function of this utility model, the movable frame and the hydraulic rod form a lifting structure.

[0010] As a preferred embodiment of the present invention, a push plate is fitted onto the surface of the square tube liner, a fixing bolt passes through the surface of the push plate, a threaded rod passes through the bottom side of the push plate, the threaded rod is mounted on the side surface of the processing table via a bearing, a servo motor is mounted on the side surface of the bracket, and the threaded rod is mounted on the output end of the servo motor.

[0011] In a preferred embodiment of this utility model, a mold with an automatic burr removal function is provided, wherein the push plate and the square tube liner are slidably connected, and the push plate and the fixing bolt are threadedly connected.

[0012] In a preferred embodiment of this utility model, a mold with an automatic burr removal function is provided, wherein the threaded rod and the push plate are connected by a thread.

[0013] In a preferred embodiment of this utility model, a mold with an automatic burr removal function is provided, wherein the threaded rod forms a rotating structure with the mold body via a bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, when the square tube moves to the bottom of the grinding wheel, the hydraulic rod is activated. When the hydraulic rod retracts, it can drive the movable frame to move downward. The downward movement of the movable frame can drive the grinding wheel to move downward through the drive motor. When the grinding wheel moves to the surface of the punched hole in the square tube, the drive motor drives the grinding wheel to rotate, which can grind and remove the burrs. This allows for convenient and automatic burr removal, improving the aesthetics and safety of the square tube after stamping.

[0016] In this invention, a square tube is fitted onto the surface of the inner lining of a square tube and slides to the end. When the fixing bolt rotates, it can move laterally towards the square tube. When the fixing bolt moves to the surface of the square tube, it can be fixed. When the servo motor runs, it can drive the threaded rod to rotate. When the threaded rod rotates, it can drive the push plate to slide laterally. When the push plate moves laterally, it can push the square tube to move laterally. After the square tube moves to the appropriate position, it can be punched by the stamping seat. This can realize the automatic feeding of the square tube and avoid the safety risks of manual feeding. Attached Figure Description

The processing table 2 is connected to the surface of the mold body 1, the stamping seat 3 is installed on the inner wall of the mold body 1, a bracket 4 is installed on the side surface of the mold body 1, a square tube liner 5 is connected between the bracket 4 and the mold body 1, a limiting seat 6 is connected to the surface of the processing table 2, a support plate 7 is connected to the surface of the processing table 2, a movable frame 8 is provided on one side of the support plate 7, a sliding groove 9 is opened on the surface of the movable frame 8, a T-shaped slider 10 is connected to the side surface of the support plate 7, a hydraulic rod 11 is connected to the lower surface of the movable frame 8 installed on the processing table 2, a drive motor 12 is installed on the surface of the movable frame 8, and a grinding wheel 13 is connected to the output end of the drive motor 12.

[0028] First, the square tube is fitted onto the surface of the inner liner 5 of the square tube. When the power mechanism of the mold body 1 is running, it can drive the stamping seat 3 to move downward. When the stamping head of the stamping seat 3 moves to the surface of the square tube, a hole can be punched on the surface of the square tube.

[0029] Preferably, the slide groove 9 and the T-shaped slider 10 are symmetrically arranged on both sides of the movable frame 8, and the movable frame 8 is slidably connected to the slide groove 9 and the T-shaped slider 10.

[0030] In practical use, when the movable frame 8 is subjected to a force, it can drive the slide groove 9 to slide on the surface of the T-shaped slider 10, which can limit the movement direction of the movable frame 8.

[0031] Preferably, the movable frame 8 and the hydraulic rod 11 form a lifting structure.

[0032] In practical use, the hydraulic rod 11 can drive the movable frame 8 to move longitudinally when it runs. The longitudinal movement of the movable frame 8 can drive the grinding wheel 13 to move longitudinally through the drive motor 12, thereby adjusting the height of the grinding wheel 13.

[0033] Preferably, a push plate 14 is fitted onto the surface of the square tube liner 5, a fixing bolt 15 passes through the surface of the push plate 14, a threaded rod 16 passes through the bottom side of the push plate 14, the threaded rod 16 is mounted on the side surface of the processing table 2 through a bearing 17, a servo motor 18 is mounted on the side surface of the bracket 4, and the threaded rod 16 is mounted on the output end of the servo motor 18.

[0038] Working principle: When using this square tube punching die, firstly, the square tube is fitted onto the surface of the square tube liner 5 and slid to the end. Then, the fixing bolt 15 is rotated. When the fixing bolt 15 rotates, it can move laterally towards the square tube. When the fixing bolt 15 moves to the surface of the square tube, it can be fixed. Then, the servo motor 18 can be run. When the servo motor 18 runs, it can drive the threaded rod 16 to rotate. When the threaded rod 16 rotates, it can drive the push plate 14 to slide laterally on the surface of the square tube liner 5 through the threaded connection. When the push plate 14 moves laterally, it can push the square tube to move laterally. After the square tube moves to the appropriate position, it can be punched through the stamping seat 3.

[0039] When the push plate 14 pushes the square tube and drives the round hole to the bottom side of the grinding wheel 13, the hydraulic rod 11 can be operated. When the hydraulic rod 11 retracts, it can drive the movable frame 8 to move downward. The downward movement of the movable frame 8 can drive the grinding wheel 13 to move downward through the drive motor 12. When the grinding wheel 13 moves to the surface of the square tube punch, the drive motor 12 drives the grinding wheel 13 to rotate, which can grind and remove the burrs.
