Description

Technical Field

[0001] This utility model relates to the field of seamless tube punching technology, specifically to a seamless tube punching and blanking device. Background Technology

[0002] In seamless tube production, billet preparation, as the first process, directly impacts yield, performance, and efficiency. Currently, two common methods are used: mechanical drilling and hollow rod die piercing. Mechanical drilling produces a large amount of aluminum shavings, resulting in the lowest material utilization rate. Furthermore, it requires a wide range of drill bits of varying sizes depending on product specifications, making production inconvenient. Its advantage is the simplicity of the equipment. Hollow rod piercing, on the other hand, uses a hollow rod die to penetrate the center of an aluminum rod, compressing the material into the hollow rod before ejecting a thin aluminum rod. This process essentially transforms aluminum shavings into aluminum rods, facilitating recycling. However, it also complicates the die structure and increases the risk of clogging. It also places certain precision requirements on the equipment, as the piercing process is prone to deviation, which is detrimental to subsequent processes.

[0003] Existing seamless tube punching and blanking equipment cannot convert aluminum chips or pressure bars into effective workpiece materials, which easily leads to eccentricity problems, low product precision, and low degree of automation. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a seamless tube punching and blanking device. This device transforms aluminum chips or pressure bars into effective materials for the workpiece, solves the eccentricity problem, improves product accuracy, increases automation, and enables online piercing and blanking.

[0005] The technical solution adopted by this utility model to solve its technical problem is a seamless tube punching and blanking device, including a die cylinder, a guide pad, a punch rod and a mounting base. The die cylinder has a through structure and a guide pad is provided at the upper end of the die cylinder. The punch rod passes through the guide pad and a punch head is installed at the bottom end of the punch rod by a screw. A support rod is provided at the bottom end of the die cylinder.

[0006] A workpiece is disposed between the guide pad and the support rod, and a heating cavity is provided in the side wall of the mold cylinder. Electric heating plates are installed in the heating cavity at equal intervals by screws.

[0007] By adopting the above technical solutions, the seamless tube punching and blanking device transforms aluminum chips or pressure bars into effective materials for the workpiece, solves the eccentricity problem, improves product accuracy, increases automation, and realizes online piercing and blanking.

[0008] Specifically, a mounting base is provided on the outer side of the mold cylinder, and a protective plate is provided on the outer side of the mounting base.

[0009] By adopting the above technical solution, the mounting base is used to fix the mold cylinder and transmit the punching force, while the protective plate provides protection.

[0010] Specifically, a mold support frame is bolted to the bottom of the mold cylinder.

[0011] Specifically, both sides of the guide pad and the support rod are connected to the mold cylinder by bolts.

[0012] By adopting the above technical solution, it is easy to install and disassemble, and easy to separate the guide pad and support rod.

[0013] Specifically, the punch is made of titanium alloy.
