Description
Technical field
The utility model belongs to trolley coach door angle manufacturing technology field, and in particular to a kind of door of stainless steel rail car
Angle mould.
Background technology
Door angle is the face component on the doorframe on stainless steel rail car, the on the door presentation quality at angle and formed precision requirement
It is higher.Mould structure of the prior art uses usual pressure spring and is combined realization shaping with machine tool air cushion power.But
There is following technological deficiency in prior art：Usual pressure spring force is small, can only play material returned effect, depend merely on the list of machine tool air cushion power
Direction periphery binder, it is impossible to effectively prevent the deformation of blank material mid portion in the forming process of door angle from arching upward, causes an angle shaping
There is raised technological deficiency at mid portion Pingdu difference and fillet afterwards.
Utility model content
The purpose of this utility model is to provide a kind of door angle mould, solves after the shaping of door angle present in prior art
There is the technical problem of projection at mid portion Pingdu difference and fillet.
The utility model technical solution adopted for solving the technical problem is as follows：
Door angle mould, it include lower template, cope plate, die fixed seat, stripper, multiple nitrogen springs, four
Die plate insert, four guide pillars, four guide pin bushings, holding pad, four holding pad inserts, punch-pin and punch-pin fixed seat；In cope plate
Portion is provided with multiple through holes in crossing distribution, and multiple nitrogen springs are connected on the middle part of stripper and end in cross,
The upper end of multiple nitrogen springs is corresponded in the through hole of insertion cope plate；During stripper is decussate texture, die fixed seat
Portion is provided with a cross cavity for being used to accommodate stripper, and the angle of bottom four of die fixed seat, which is respectively provided with one, to be used to accommodate
The groove of die plate insert；Punch-pin and punch-pin fixed seat are decussate texture, and the middle part of holding pad is convex for accommodating provided with one
The cross cavity of mould and punch-pin fixed seat, four, the top angle of holding pad, which is respectively provided with one, to be used to accommodate the recessed of holding pad insert
Groove；Four guide pillars are distributed on four angles of lower template, and four guide pin bushings are respectively distributed on four angles of cope plate, each guide pillar
When one guide pin bushing of correspondence, cope plate and lower template fastening, four guide pin bushing correspondences are enclosed within four guide pillars；Punch-pin fixed seat and lower mould
Plate is threadedly coupled, and punch-pin is threadedly coupled with punch-pin fixed seat, and holding pad is threadedly coupled with holding pad insert, die plate insert and cavity plate
Fixed seat is threadedly coupled.
The beneficial effects of the utility model are：The utility model is using the nitrogen spring conduct that multiple strokes are big, pressure is big
Apply pressure-plate-force and the flexible member of material returned power at the top of upper mould, enough thrusts are provided for an angle forming process；Stripper
Initial position is less than shaping upper, it is ensured that materials and parts stripper before die plate insert applies forming force to blank material is tightly pressed from both sides with punch-pin
Tight blank material, prevents that blank material from producing Free Transform, so as to effectively prevent deformation in the middle part of materials and parts, whole forming process keeps original
Pingdu；When the utility model ensure that materials and parts start deformation under punch-die effect, the holding pad of air cushion applying power and upper mould
Blank periphery is compressed；Door angle is molded under air cushion power and the dual force collective effect of nitrogen spring active force, solves materials and parts
In forming process the problem of Pingdu is poor in the middle part of materials and parts caused by the small generation of blank material intensifying force is freely deformed, while molding part fillet
Locate bump defects to disappear, effectively improve stainless steel rail car door angle Forming Quality；High-quality is used in the forming process of door angle
Drawing oil, effectively protection materials and parts surface, it is to avoid materials and parts and mould produce scuffing.
Brief description of the drawings
Fig. 1 is the configuration schematic diagram of the utility model door angle mould；
Wherein, 1, lower template, 2, cope plate, 3, die fixed seat, 4, stripper, 5, nitrogen spring, 6, die plate insert, 7,
Guide pillar, 8, guide pin bushing, 9, holding pad, 10, holding pad insert, 11, punch-pin, 12, punch-pin fixed seat.
Embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, door angle of the present utility model mould is the door under a kind of air cushion and the effect of nitrogen spring dual force
Angle mould.This angle mould includes lower template 1, cope plate 2, die fixed seat 3, stripper 4, multiple nitrogen springs
5th, four die plate inserts 6, four guide pillars 7, four guide pin bushings 8, holding pad 9, four holding pad inserts 10, punch-pin 11 and punch-pin are fixed
Seat 12.
The middle part of cope plate 2 is provided with multiple through holes in crossing distribution, and multiple nitrogen springs 5 are connected in cross to move back
The middle part of flitch 4 and the upper surface of end, the upper end of multiple nitrogen springs 5 are corresponded in the through hole of insertion cope plate 2.Multiple nitrogen
Spring 5 is not when working, and the lower surface of the initial position of stripper 4 is less than the lower surface of cope plate 2, to ensure in die plate insert 6
Blank material can be clamped with punch-pin 11 by applying stripper 4 before forming force to blank material, prevent that blank material from producing Free Transform, so that
Effectively prevent deformation in the middle part of materials and parts.
Stripper 4 is decussate texture, and the middle part of die fixed seat 3 is provided with a cross for being used to accommodate stripper 4
