Abstract

The utility model relates to a universal reverse-jacking bulging die used for stamping copper bush bulging parts. The problems that an existing universal die is poor in universality, and product quality is poor are solved. The universal reverse-jacking bulging die comprises an upper die base, a special screw, a bulging rubber column, an upper die, a positioning guide base, a lower die base, a lower die, an air cushion plate, an air cushion rod and a connecting plate. The bulging rubber column is connected to the upper die base through the special screw and the connecting plate, the positioning guide base is connected to the lower die base, the air cushion rod is matched with the air cushion plate which is matched with the bulging rubber column, the upper die and the lower die form a bulging female die after being compressed, the position, where the upper die is connected with the lower die, of the bulging female die forms an annular groove, the air cushion plate can reversely jack the bulging rubber column upwards, the bulging rubber column deforms under the pressure and is similar to a bulging male die, and the annular groove in the middle of a part is bulged through the bulging male die and the bulging female die. The universal reverse-jacking bulging die is high in universality, eliminates extrusion damage and indentations produced by die dividing face joints to the part during bulging in the prior art, and ensures product quality.

Description

A kind of general anti-top expanding die
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of general anti-top expanding die.
Background technology
In metal punching part, there is the Bushing bulging part that shape is similar, size differs, this class part manufactures and designs expanding die as each part, can cause die cost to increase considerably, reduce economic benefit, and original expanding die is to adopt oblique contract transferring power to carry out bulging from horizontal direction, mould structure complexity, the impression that also has mould seam to cause on part, affects part quality, needs to increase polishing grinding indentation process.
Summary of the invention
The utility model is by a kind of general anti-top expanding die is provided, and one module multiple usages has solved that mould versatility is poor, production cost is high and the problem of poor product quality.
The utility model is achieved in the following ways:
A kind of general anti-top expanding die, comprise upper bolster, screw special, bulging rubber column, patrix, positioning and guiding seat, die shoe, counterdie, air cushion plate, air cushion bar and connecting plate, patrix is connected on upper bolster, bulging rubber column is connected on upper bolster with screw special and connecting plate, counterdie is placed on die shoe, positioning and guiding seat is connected on die shoe, air cushion bar and air cushion plate match, air cushion plate and bulging rubber column match, after compressing, patrix and counterdie form bulging die, bulging die forms annular groove at the joint of patrix and counterdie, air cushion plate is anti-top bulging rubber column upwards, bulging rubber column produces distortion and is equivalent to bulging punch under pressure, together with bulging die, the annular groove muscle in the middle of part is carried out to bulging.
The general degree of the utility model mould is high, and a mold, by changing working portion core rod, completes the bulging of multinomial part, can reduce number of molds, reduces production costs, and enhances productivity.While having eliminated bulging, crowded the hinder impression of mould die joint seam to part, has cancelled polishing indentation process, has guaranteed product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation before the utility model bulging;
Fig. 2 is the structural representation after the utility model bulging;
Fig. 3 is the top view of Fig. 2;
Fig. 4 is product parts figure.
The specific embodiment
As Figure 1-3, the utility model is used for punching press Bushing bulging part, comprises upper bolster 1, screw I2, screw special 3, bulging rubber column 4, patrix 5, positioning and guiding seat 6, die shoe 7, screw II8, counterdie 9, air cushion plate 10, air cushion bar 11 and connecting plate 12.
Patrix 5 use screw I2 are connected on upper bolster 1, bulging rubber column 4 is connected on upper bolster 1 with screw special 3 and connecting plate 12, counterdie 9 is placed on die shoe 7, positioning and guiding seat 6 use screw II8 are connected on die shoe 7, patrix 5 and counterdie 9 are positioned to guiding, air cushion bar 11 matches with air cushion plate 10, and air cushion plate 10 matches with bulging rubber column 4.
Patrix 5 forms bulging die after compressing with counterdie 9, bulging die forms annular groove at the joint of patrix and counterdie, air cushion plate 10 is anti-top bulging rubber column 4 upwards, bulging rubber column 4 produces distortion and is equivalent to bulging punch under pressure, together with bulging die, the annular groove muscle in the middle of part 13 (seeing Fig. 4) is carried out to bulging.
During use, upper bolster 1 is connected with lathe slide block, the blank of part 13 (having rolled up as drum) is placed on to counterdie 9 and positions.When lathe is descending, first patrix 5 compresses (seeing Fig. 1) with counterdie 9, then air cushion plate 10 is by air cushion bar 11, anti-top bulging rubber column 4 upwards under the effect of lathe cylinder air pressure, bulging rubber column 4 produces distortion and is equivalent to bulging punch under pressure, composition bulging die after patrix 5 is closed with counterdie 9, carries out bulging (seeing Fig. 2) by the annular groove muscle in the middle of part.After slide block is up, part is taken out, so just completed the Bulging Process of a part.
