Description

Technical Field

[0001] The utility model relates to the technical field of drawing dies, in particular to a drawing die for a thin-walled rectangular tube. Background Art

[0002] During the production and processing of rectangular tubes, the round tubes are usually pulled by the cooperation between the round tubes, the drawing die and the external moving clamps, and the round tubes are squeezed and deformed under the action of the drawing die to form rectangular tubes.

[0003] When the existing drawing die is used, the die is usually installed on the inner side of the die seat by bolts. However, in actual use, when the tube moves inside the drawing die, a large pulling force will be caused to the drawing die, which will cause a large pulling force between the die and the die seat, which is easy to cause damage to the bolts, making it impossible to use the die and the die seat stably. For this reason, we propose a thin-walled rectangular tube drawing die. Utility Model Content
