Abstract
The utility model discloses a stamping die for stainless steel tube forming. The stamping die comprises an upper die component, a lower die holder, a three-section concave die, an inner core, a three-section die holder and a lower die holder bottom plate. The lower die holder is fixed to the lower die holder bottom plate. The center of the lower die holder is provided with a big-end-up inclined hole. The three-section die holder is movably arranged in the inclined hole in the center of the lower die holder in a sleeved mode. The outer wall of the three-section concave die is of an inverted cone shape and is arranged in the inclined hole in the center of the lower die holder in a sleeved mode. The inner core is arranged in an inner cavity of the three-section concave die in a sleeved mode, and the lower end of the inner core is fixed to the three-section die holder. A gap allowing a stainless steel tube to penetrate through is formed between the inner core and the three-section concave die. A guide mechanism is arranged between an upper die holder bottom plate and the lower die holder bottom plate. Due to the fact that the concave die is designed to be a three-section concave die, after a thin-walled tube is subjected to broaching forming, the thin-walled tube can separate from the inclined hole in the center of the lower die holder and can be easily taken out of the lower die holder; moreover, the three-section concave die and the inner core enable the thin-walled tube to be seated and not to deform in the stamping process.
Description
Technical field
The utility model relates to a kind of cold punching die, particularly relates to a kind of stainless steel materials in the tube shaping punching compression mould.
Background technology
Diel, is in Cold Press Working, metal material processing is become to a kind of special process equipment of part.In the production of diel extensive use automobile making, commodity production, various formers.Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacture.Light-wall pipe cold punching die, in forming process, often occurs that light-wall pipe cannot the material returned and the problem such as lower seat distortion, and for this reason, dealer is badly in need of addressing this problem.
This diel is comprised of mould bases, upper and lower die holder, die, punch etc.; The design of each component part standardized module, changes die, punch and realizes fast the replacing of each operation frock; Main feature is, Die Design becomes three valve structures, and having solved light-wall pipe cannot the material returned and the difficult problem such as lower seat distortion.
Utility model content
The purpose of this utility model is to provide a kind of material returned, stainless steel materials in the tube shaping punching compression mould that product quality is high of being easy to.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of stainless steel materials in the tube shaping punching compression mould, and it comprises upper bolster base plate, guiding mechanism, fixed cover, material returned rubber cushion, punch, stripper, material returning sleeve, die shoe, three lobe dies, inner core, three lobe die holders, die shoe base plate; Described fixed cover is bolted on upper bolster base plate, the upper end of punch leans on upper bolster base plate, on the hanging platform of the pressured punch of fixed cover and punch is fixed on upper bolster base plate, gap, stripper middle part is socketed on punch and stripper periphery via clearance is overlapped on extension bolt, stay bolt upper end is fixedly screwed onto on upper bolster base plate, and material returned rubber cushion is set on upper bolster base plate and between stripper; Described die shoe is fixed on die shoe base plate, die shoe central authorities have a up big and down small inclined hole, three lobe die holder activities are nested with in the inclined hole of die shoe central authorities, the outer wall of three lobe dies is be back taper and be nested with in the inclined hole of die shoe central authorities, inner core is nested with at three lobe die inner chambers and its lower end and is fixed on three lobe die holders, between inner core and three lobe dies, has the gap that accommodating stainless steel tube penetrates; Between upper bolster base plate and die shoe base plate, be provided with guiding mechanism.
Described guiding mechanism consists of guide pillars and bushes; Described guide pillar activity is nested with in guide pin bushing; Described guide pillar lower end is fixed on contour pad, and contour pad is fixed on die shoe base plate, and guide pin bushing is fixed on upper bolster base plate.
Adopt after such scheme, because counterdie of the present utility model mainly consists of parts such as die shoe, three lobe dies, inner core, three lobe die holders, die shoe base plates, Die Design becomes three lobe cavity die structures; light-wall pipe is after reaming-forming; light-wall pipe can depart from the inclined hole of die shoe central authorities; light-wall pipe can be easy to take out from die shoe, and three lobe die and inner cores of the utility model setting, makes to be sitting in punching course and can not to be out of shape under light-wall pipe.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
