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
The present invention relates to punching press sheet metal deep drawing lubrication protection method, specifically a kind of method for drawing to existing high temperature alloy.
Background technology
Pull and stretch is to utilize particular manufacturing craft with stamping-out or cut out a kind of Sheet Metal Forming Technology method that the resulting plate blank in back is made the hollow object of opening.Drawing sequence occupies very consequence in punching production.Use deep-drawing technique, can make tubular, stairstepping, sphere, square box shaped and other erose thin plate workpiece.If pull and stretch cooperates with other process for stamping and forming, also can make shape and be complicated stamping parts.But the processing dimension scope of drawing part also is quite widely, and little extremely several millimeters clock and watch part to automobile, the airplane parts of 2～3 meters profiles, can be made with method for drawing greatly.Therefore, deep-drawing technique is used widely in industrial department such as electronics, electrical equipment, instrument, automobile, aircraft and daily living article are made.
Existing deep-drawing technique method obtains the pull and stretch part with conventional method always, i.e. direct pull and stretch part after panel surface is coated with one deck conventional lubricants.Adopt this mode, only be applicable to the pull and stretch of the material that general plasticity is good, for the pull and stretch of high-temperature alloy material, normal generation is pulled and the drawing crack part in a large number.Therefore, for a change the high-temperature alloy material part is pulled and the drawing crack phenomenon in a large number, the invention provides the guard method of a kind of high temperature alloy sheet metal deep drawing.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of new high temperature alloy method for drawing; this method is that lubricating oil is evenly coated on the upper and lower surface of high temperature alloy plate; the plastic sheeting that covering is gone up and the high temperature alloy plate is onesize thereon is as diaphragm again; the thickness of diaphragm is generally 0.04～0.06mm; put into the mould drawing and forming then, remove diaphragm and lubricant behind the part drawing and forming.Main method step: two-sided covering plate size diaphragm (0.04～0.06 plastic sheeting)-part drawing and forming-removal diaphragm-cleaning lubricant before the two-sided lubricant that is coated with before the part sheet metal deep drawing--the part pull and stretch.Adopt this method, can reduce the coefficient of friction between material and mould, its drawing pressure reduces by 30%, improved the distortion of materials degree, reduced the Limit Drawing coefficient, by practice, the method for the invention can be reduced to 0.37～0.40 from 0.45～0.47 with former Limit Drawing coefficient.Compared with prior art, use the method for the invention to carry out the pull and stretch that high temperature closes life sheet material, part takes out from mould easily, and surface quality of workpieces is good.When adopting original process processing parts; workpiece is pulled or drawing crack easily; after adopting the method for the invention; 0.04～0.06 plastic sheeting on the pad of two sides after part is coated with lubricant; utilize the distinctive extensibility protection of plastic sheeting pull and stretch part; the final piece surface that solves is pulled and the drawing crack phenomenon, and workpiece is essentially no to be pulled and the drawing crack phenomenon.
Description of drawings
Fig. 1 adopts the inventive method the high temperature alloy plate to be carried out the embodiment schematic diagram of pull and stretch on forcing press.
Among the figure: 1-drift, 2-holding pad, 3-lubricating oil, 4-diaphragm, 5-high temperature alloy plate, 6-die, 7-ejecting mechanism.
The specific embodiment
Below in conjunction with the described embodiment of accompanying drawing high temperature alloy sheet metal deep drawing method of the present invention is described in further detail.
In the embodiment in figure 1; lubricating oil 3 is evenly coated on the upper and lower surface of high temperature alloy plate 5; cover to go up thereon again and diaphragm 4 that high temperature alloy plate 5 is onesize; be put into then on the forcing press and carry out pull and stretch with 1 pair of high temperature alloy plate of drift 5; add man-hour; holding pad 2 is pushed down the outer ring of high temperature alloy plate 5, and after the inner ring metal flow entered die 6 arrival certain depths, ejecting mechanism 7 ejected the pull and stretch part.
During pull and stretch, the interaction of blank inside having taken place owing to blank is stressed, made material internal radially produce tension, is tangentially producing compression.Under tension, compression acting in conjunction, plastic deformation has taken place earlier in the material of ledge zone, and constantly is drawn into die, thereby becomes the cylindrical member of different wall.The deformation characteristics of drawing process is that the big basal area from blank becomes the long-pending cylindrical member of light section.This moment, the drawing coefficient of material was the ratio of the basal area before basal area and the pull and stretch behind each pull and stretch, had determined the height of drawing part precision and the quality of quality.In production practices, always wish that drawing coefficient is the smaller the better, because less drawing coefficient value illustrates that deformation extent is big, number of drawing can suitably reduce.Especially concerning producing in enormous quantities, every minimizing one procedure has very big practical significance to producing, and reduces the cost of stamping parts.But it is too small that drawing coefficient is got, and then drawing part easily produces wrinkling and fracture and serious attenuation phenomenon take place.The factor that influences drawing coefficient in the actual production has several main aspects such as the relative thickness, pull and stretch mode, pull and stretch program, mould structure, lubricating condition of the mechanical performance of material, material.Under the relative thickness of the mechanical performance of material, material, pull and stretch mode, pull and stretch program, the geostationary situation of mould structure; good lubrication protection condition just becomes the key issue that drawing coefficient is reduced; high-temperature alloy material pull and stretch of the present invention guard method; simple to operate, stable; when adopting this method to produce high temperature alloy pull and stretch part; no part is pulled and the drawing crack phenomenon, thereby reduces the subsequent handling time spent, improves product percent of pass.Therefore, can reduce labour intensity, reduce the consumption of artificial muscle power, increase work efficiency and shorten the process-cycle, satisfy requirements of large-scale production.
