Abstract
The invention relates to a forming die by solid particle medium and radial thrust, comprising a convex die, a concave die, a blank holder, a seal plate, a top plate, solid particles, a nitrogen cylinder, a top rod, a lower die holder and the like, wherein the nitrogen cylinder is arranged on the lower die holder, and the working end of the nitrogen cylinder penetrates into a swaging plate and contacts with the top plate which is arranged in the blank holder to be against the lower surface of the top plate; and the seal plate is arranged on the swaging plate, the seal plate forms a sealed space with the concave die, the blank holder, the top plate and the formed part, the solid particles are placed in the sealed space, and the radial thrust is transmitted to a sheet material by the nitrogen cylinder via solid particle medium; or the swaging is completed by the nitrogen cylinder and radial thrust is provided by a machine air cushion. The die has the advantages of simple structure, high safety, high reliability, no pollution, easy forming and sound effect.
Description
Technical field
The invention belongs to Stamping Die Technology, be specifically related to a kind of shaping dies by solid particle medium and radial thrust, mainly is at the mould that radial pressure can be provided.
Technical background
Common shaping dies does not have radial thrust usually, is shaped to drive plate by punch, finishes to the die pulling; Can not produce radial thrust during moulding, moulding tissue odds is even; And, the cupping tool of band radial thrust hydraulic means, radial thrust is realized that by fluid pressure though can produce radial thrust during moulding, its sealing problem is difficult to solve, and this mould structure complexity, cost is higher, the needs of incompatibility domestic consumer.
Summary of the invention
The present invention is directed to the insoluble problem of cupping tool sealing problem that common shaping dies does not have radial thrust and is with hydraulic radial, a kind of shaping dies by solid particle medium and radial thrust is provided, thereby realize providing radial thrust, solve sealing problem; Reduce the cost of mould simultaneously.
Technical scheme of the present invention is as follows: a kind of shaping dies by solid particle medium and radial thrust, include punch, die, blank holder, nitrogen cylinder and die shoe, described punch is installed on the die shoe, die is movably, the nitrogen cylinder is installed on the die shoe, and the working end of push rod is passed die shoe and withstood blank holder; It is characterized in that: the working end of described nitrogen cylinder penetrates blank holder, contacts with the lower surface of top board in being arranged on blank holder; Sealing plate is installed in above the blank holder, and solid particle is set on blank holder; In forming process, sealing plate, top board, die, blank holder and blank form an enclosure space, and solid particle is full of in the enclosure space.
Further feature is: enclosure space is symmetricly set on the blank holder both sides.
The topmost improvement of the present invention is that the working end of nitrogen cylinder penetrates blank holder, contacts with the lower surface of top board in being arranged on blank holder; Sealing plate is installed in above the blank holder, and sealing plate and die, blank holder, top board and blank form an enclosure space in forming process, and solid particle is arranged in the enclosure space.
This mould structure is simple, and radial thrust is delivered on the plate by solid particle medium by the nitrogen cylinder, realizes reliable, pollution-free; When radial thrust is provided, solved sealing problem; Reduce the cost of mould simultaneously.This mould structure also can be realized binder by the nitrogen cylinder, realizes radial thrust by the lathe air cushion.Compare with common shaping dies, it is easier to be shaped, and effect is very remarkable.
Description of drawings
Fig. 1 is the shaping dies of the present invention by solid particle medium and radial thrust.
Among the figure: 1-sealing plate, 2-top board, 3-solid particle, 4-die, 5-blank, 6-blank holder, 7-nitrogen cylinder, 8-punch, 9-push rod, 10-die shoe, 11-enclosure space.
The specific embodiment
Referring to Fig. 1, be depicted as a kind of shaping dies by solid particle medium and radial thrust, comprise punch 8, die 4, push rod 9, die shoe 10, sealing plate 1, top board 2, solid particle 3, blank 5, blank holder 6, nitrogen cylinder 7.Die 4 is installed on the inner slide and (does not illustrate among the figure), and die 4 can move, and punch 8 is installed on the die shoe 10, the moulding in the die cavity of die 4 and punch 8 of described blank 5.Blank holder 6 is arranged on below the die 4, nitrogen cylinder 7 lower ends are installed on the die shoe 10, and its working end (upper end) passes blank holder 6, contact with the lower surface of top board 2 in being arranged on blank holder 6 counterbores, withstand the lower surface of top board 2, promote top board 2 upper and lower motions during 7 work of nitrogen cylinder; Nitrogen cylinder 7 is two, is symmetrically arranged on die shoe 10.Sealing plate 1 is installed in above the blank holder 6, and sealing plate 1 can form an enclosure space 11 with die 4, blank holder 6, top board 2 and blank 5 in forming process, and solid particle 3 is full of in the enclosure space 11 when moulding; When moulding not, solid particle 3 is in the counterbore of blank holder 6, when nitrogen cylinder 7 raises, upwards ejected by top board 2, thereby prevent that solid particle 3 from splashing away, can provide a thrust radially simultaneously, blank 5 is subjected to the radial thrust of solid particle 3 in forming process; Be symmetricly set on blank holder 6 both sides at the formed enclosure space 11 in the left and right two ends of blank holder 6 among the figure, the radial thrust that left and right sides solid particle 3 is produced equates.Under nitrogen cylinder 7 effect, the solid particles 3 that top board 2 promotes in the enclosure spaces 11 move up and down synchronously, regulate what (solid particles 3 that flow out in the blank holder 6 what) that solid particle 3 flows out blank holders 6.Left and right two nitrogen cylinders 7 are fixed on the die shoe 10, guarantee that the solid particle 3 in left and right two enclosure spaces 11 moves up and down synchronously, guarantee that the quantity of the solid particle 3 of outflow blank holder 6 equates, strengthen its running stability; The radial thrust that guarantees the left and right sides equates.
The upper end of push rod 9 contacted with the following of blank holder 6, withstand on blank holder 6 below, clamping pressure or cushion effect are provided.
Radial solid particle 3 of the present invention, shaping solid particle 10 mainly adopt steel ball, steel ball, Metal Ball or the suitable particle of other performances, satisfy the needs of moulding extruding.
