Description

Technical Field

[0001] The utility model relates to a continuous drawing die for automobile fasteners, belonging to the technical field of continuous drawing dies. Background Art

[0002] A continuous drawing die is a tool for metal processing. It can continuously draw metal materials into the required shapes and sizes. Such a die usually consists of multiple components, including a die base, a die core, a die sleeve, etc. The working principle of the continuous drawing die is to place the metal material in the die, and then make the die core move downward through mechanical force or hydraulic pressure, so as to continuously draw the metal material. During the drawing process, the shape and size of the metal material will gradually change until the required requirements are met.

[0003] There is a prior continuous drawing die for automobile fasteners with the patent number CN220901593U. This device drives the clamping piece to clamp the port of the die on the center block by using the electric push rod on the adjusting side plate. The rubber blocks on the surfaces of the clamping piece and the center block increase the clamping force. The drawing rod is slowly pulled backward under the control of an external motor. The drawing rod drives the clamping frame to move backward, so as to start drawing the die. It can realize drawing the die, and the structure is more convenient and has a wider application range than the existing device. However, this device does not have the function of continuously drawing automobile fasteners. The continuous drawing die is a progressive mechanical or hydraulic extrusion drawing, rather than direct drawing; and when drawing automobile fasteners, there is no automatic position conversion structure and drawing reset structure in this device, so the automatic continuous drawing process of automobile fasteners cannot be realized.
