Embodiment Construction

[0007] The method for deep-drawing a superalloy sheet of the present invention will be further described in detail with reference to the embodiments described in the accompanying drawings.

[0008] exist figure 1 In the embodiment of the present invention, the upper and lower surfaces of the superalloy sheet 5 are evenly coated with lubricating oil 3, and then covered with a protective film 4 of the same size as the superalloy sheet 5, and then placed on the press with a punch 1. Deep-draw the high-temperature alloy sheet 5. During processing, the binder plate 2 presses the outer ring of the high-temperature alloy sheet 5, and the inner ring metal flows into the die 6 to reach a certain depth, and the ejector mechanism 7 will draw the part ejected.

[0009] During deep drawing, the internal interaction of the blank occurs due to the force on the blank, which causes tensile stress in the radial direction and compressive stress in the tangential direction inside the material. ...

Abstract

A high-temperature alloy plate drawing method includes: evenly applying lubricant to the upper and lower surfaces of a high-temperature alloy plate, covering the high-temperature alloy plate with plastic films, as large as the high-temperature alloy plate, to serve as protective films which are 0.04-0.06mm in thickness generally, drawing the high-temperature alloy plate by a die, and removing the protective films and the lubricant after draw-forming of the part. The high-temperature alloy plate drawing method mainly includes the steps of applying the lubricant to double surfaces of a plate part before drawing, covering the double surfaces of the plate part with the protective films (0.04-0.06mm plastic films) as large as the plate part before drawing, drawing the part, removing the protective films, and cleaning the lubricant. By the aid of the method, friction coefficient between material and the die can be reduced, drawing force is reduced by 30%, deforming degree of the material is increased, and limit drawing coefficient is reduced. Practice shows that the original limit drawing coefficient can be reduced from 0.45-0.47 to 0.37-0.40 by using the method.

Description

technical field [0001] The invention relates to a lubricating and protecting method for deep-drawing of stamping sheet metal, in particular to a deep-drawing method for existing high-temperature alloys. Background technique [0002] Deep drawing is a stamping process that uses a special die to make a flat blank that is punched or trimmed into a hollow part with an opening. The deep drawing process occupies a very important position in stamping production. With the deep drawing process, thin plate workpieces with cylindrical, stepped, spherical, square box and other irregular shapes can be made. If deep drawing is combined with other stamping forming processes, stamping parts with complex shapes can also be manufactured. The machinable size range of deep-drawing parts is also quite wide. Watch parts as small as a few millimeters, and automobile and aircraft parts with a profile as large as 2 to 3 meters can be made by deep-drawing methods. Therefore, the deep drawing proce...
