Copper pipe drawing device

Abstract

The invention relates to the field of machining and discloses a copper pipe drawing device. The copper pipe drawing device comprises a base, a die, a core rod, a traction mechanism and a drive motor. The die is fixed to the base. The core rod is matched relative to the die. A sliding rail is arranged on the base. The traction mechanism is connected to the sliding rail in a sliding manner, and a clamp is further arranged on the traction mechanism. The sliding rail is further provided with a sliding seat connected with the sliding rail in a sliding manner. A hydraulic oil tank, a hydraulic pump, a sealing cover and a pressure control valve are arranged on the sliding seat. One end of the sealing cover is an opening end, and the other end of the sealing cover is a fixed end fixed to the sliding seat, wherein the opening end is provided with a locking mechanism. The pressure control valve and the hydraulic pump are installed at the fixed end of the sealing cover and communicate with a cavity of the sealing cover. The sliding seat, the die and the traction mechanism are sequentially arranged on the base, and the opening end of the sealing cover is opposite to the die. The core rod of the copper pipe drawing device does not need to be fixed, and therefore the length of extrusion raw material pipes is not limited; and the device can be used for machining the long extrusion raw material pipes, and therefore the clamping times can be reduced, and the efficiency is improved.

AI Technical Summary

Benefits of technology

Invention describes an apparatus that uses liquid (oil) or gas instead of rods during manufacturing processes. By pressing downward against the inside surface of the cylinder containing the raw materials being processed, it expands them without limiting their size. It then removes excessive moisture from these tubes while still keeping everything fixed together. Additionally, when used repeatedly over multiple times, there are fewer parts wearing out faster than other components due to increased resistance caused by repeated use. Overall, this technology allows for more efficient production of products made up of different types of materials compared to traditional methods like casting moldings.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficient use of drawings machines during production processes due to limitations associated with traditional methods like empty drafting and free standing casting techniques. These issues include wasteful consumption of resources caused by excessive machining time and difficulty in achieving desired dimensions within certain tolerances.
