Pressure dies for dust-free drawing of aluminum-clad steel

Abstract

The invention relates to the technical field of aluminum-clad steel, in particular to a pressure die for dust-free drawing of aluminum-clad steel. This pressure die for dust-free drawing of aluminum-clad steel includes a wire drawing die and a pressure die, two ends of the pressure die are provided with hard alloy, and the wire drawing die and the pressure die are connected by a transition joint, and the transition The joint and the pressure die are fixed in the cage, and the drawing die, the transition joint and the pressure die are provided with inner holes. This pressure mold for dust-free drawing of aluminum-clad steel can ensure the clearance requirements required for dust-free drawing of aluminum-clad steel. The installation of this structure can be completed at one time without causing the deflection of the transition joint to affect the drawing of aluminum-clad steel. Phenomenon: The inner hole of the transition joint is a little larger than the inner hole of the normal pressure die, so even if a little deformation occurs under a large pressing force, it will not affect the normal drawing of the aluminum-clad steel, and the life of the die is extended, even if the transition joint is deformed If it is too large, only one joint needs to be replaced, which saves the investment cost.

Description

technical field [0001] The invention relates to a pressure die, in particular to a pressure die for dust-free drawing of aluminum-clad steel. Background technique [0002] For a long time, the drawing process in my country's aluminum-clad steel production process has been using the traditional solid lubricant powder forced lubrication drawing technology. This technology will produce dust in the drawing and subsequent processes, which will affect the health of operators and cause air pollution. For the installation method of powder drawing pressure die and wire drawing die, see figure 1 .At the same time, the gap between the pressure die and the drawn aluminum-clad steel clad rod is relatively large. At the same time, in order to ensure that the lubricating powder does not leak, a large pressing force is added when the wire drawing die and the pressure die are connected. In order to ensure that the liquid does not leak, the pressing force is appropriately increased when the ...

Problems solved by technology

In order to ensure that the liquid does not leak, the pressing force is appropriately increased when the drawing die and the pressure die are installed, so plastic deformation occurs at the contact part between the pressure die and the drawing die. At this time, the cladding rod often breaks when the aluminum-clad steel is drawn, and After each fracture, the disassembly of the pressure mold often requires repairing the deformed part, from figure 1 It can be seen from the figure that the size of the head of the pressure die is relatively small. Such a pressure die will be scrapped after being used several times, which wastes a lot of manpower and material resources.
