Abstract
A kind of cupping tool, can solve complicated drawing parts and carry out deep-drawing technique when calculating, analyze the quality problems that may occur, the problem solving easy drawing crack exactly.Cupping tool groundwork part of the present utility model comprises: punch, die, insert, journal stirrup insert, insert, impression block.Not only 2 inserts, are arranged in 4 grooves in die and impression block respectively, and make die groove have drawing, but also have impression, guarantee that workpiece extrudes platform on inclined-plane, square boss C shape journal stirrup adopts insert, and being arranged on impression block is in order to convenient processing and manufacture.The critical piece of the utility model mould adopts combining structure, greatly facilitates mold use, maintenance and maintenance, effectively reduces mold use cost.Adopt the composite technology of shaping and shaping, ensure that the reliable and stable of product quality, realize high-quality and efficient production in enormous quantities.
Description
Technical field
The utility model relates to the drawing of workpiece, particularly the drawing of stairstepping cylindrical member, specifically a kind of cupping tool at the bottom of automobile vacuum booster shell.
Background technology
Drawing is one of most widely used technique in punching production, adopts deep-drawing technique can make the open hollow part of various shape.Because plate is in drawing process, the stressing conditions of blank each several part is very complicated.Therefore, when carrying out deep-drawing technique calculating to complicated drawing parts, be difficult to analyze the quality problems that may occur exactly.Usually solved by die trial.
Summary of the invention
The purpose of this utility model is to provide a kind of cupping tool, described this mould to solve complicated drawing parts carry out deep-drawing technique calculate time, be difficult to analyze the quality problems that may occur exactly.In existing cupping tool, plate is in drawing process, and the stressing conditions of blank each several part is very complicated.When deep-drawing technique calculating is carried out for complicated drawing parts, the quality problems that may occur can not be analyzed exactly, and easily drawing crack.
The utility model can solve the shortcoming of above-mentioned mould, and when complicated drawing parts carries out deep-drawing technique calculating, can analyze the quality problems that may occur exactly, prevent drawing crack, simple to operate, the scope of application is more extensive.
The purpose of this utility model is achieved through the following technical solutions: a kind of cupping tool, comprise cope match-plate pattern, guide pin bushing, backing plate, insert, journal stirrup insert, head part bar, die, punch, insert, very core, impression block, punch retainer, blank holder, push rod, lower bolster, it is characterized in that: described cope match-plate pattern, guide pin bushing are positioned at the upper end of patrix; Described guide pin bushing adopts interference fit press-in cope match-plate pattern; Described die block is positioned at the middle part of patrix; Described die is positioned at the lower end of patrix, and die and die block, cope match-plate pattern are with bolts.
Described a kind of cupping tool, is characterized in that: described head part bar is positioned at the center of patrix, is connected with external equipment; Described punch is positioned at the middle part of counterdie, and lower bolster is positioned at the lower end of counterdie, and punch and punch retainer, lower bolster are with bolts; Described blank holder is positioned at around punch; Described impression block is positioned at the outside of counterdie with enduring core, be connected respectively with lower bolster bolt; Described insert is with bolts with impression block, lower bolster; Described push rod is threaded with very core.
Described a kind of cupping tool, is characterized in that: described blank holder profile is the face of cylinder.
Described a kind of cupping tool, is characterized in that: one section of described push rod is polished rod, and one section is screw rod.
Operation principle of the present utility model is: operationally, first workpiece is placed on blank holder, is located by the external cylindrical surface of blank holder, because this part flange is comparatively large, for making accurate positioning, holds workpiece with very core is auxiliary.During mold work, die is descending with slider of punch, first workpiece pressing under push rod, very core and blank holder effect; Along with slider of punch continues descending, die and punch, journal stirrup insert, insert, insert, impression block carry out the shaping of workpiece; When mould arrives bottom dead centre, the drawing and forming of workpiece terminates; At this moment second and the 3rd step inclined-plane place individual impression platform and square boss C shape journal stirrup be all shaped, the little barrel sizes in bottom also puts in place substantially; Finally, mould moves upward with slide block, and very workpiece ejects by core and blank holder under the effect of push rod from punch and impression block, and workpiece pushes from die by push rod, and drawing work completes.
The utility model is compared with prior art, and its effect is actively with obvious.The critical piece of the utility model mould adopts combining structure, greatly facilitates mold use, maintenance and maintenance, effectively reduces mold use cost.Adopt the composite technology of shaping and shaping, ensure that the reliable and stable of product quality, achieve high-quality and efficient production in enormous quantities.For guarantee punch, die have enough intensity and toughness, consider processing technology, punch, negative molding material select Cr12 simultaneously, and heat treatment hardness requires to reach 58 ~ 62HRC.Consider the area of square boss C shape journal stirrup insert more greatly, thinner, therefore material selection Crl2MoV, its heat treatment deformation is little, hardness high (heat treatment hardness is 56 ~ 60HRC), wearability is good, has good manufacturability, effectively improves the mold use life-span.
Accompanying drawing illustrates:
Accompanying drawing is drawing and forming mould.
Detailed description of the invention: workpiece 7 is placed on blank holder 13, is located by the external cylindrical surface of blank holder 13, because this part flange is comparatively large, for making accurate positioning, holds workpiece with very core 9 is auxiliary.During mold work, die 8 is descending with slider of punch, first workpiece pressing under push rod 15, very core 9 and blank holder 13 act on; Along with slider of punch continues descending, die 8 with punch 12, journal stirrup insert 5, insert 4, insert 14, impress the shaping that block 10 carries out workpiece; When mould arrives bottom dead centre, the drawing and forming of workpiece terminates; At this moment second and the 3rd step inclined-plane place 4 impression platforms and square boss C shape journal stirrup be all shaped, the little barrel sizes in bottom also puts in place substantially; Finally, mould moves upward with slide block, and very workpiece ejects by core 9 and blank holder 13 under the effect of push rod from punch 12 and impression block 10, and workpiece pushes from die 8 by push rod 6, and drawing work completes.
