Abstract

The utility model relates to a double directional explosive forming container closing device, which uses the exploding energy of the explosive as the dynamic force, so two shell covers for containers can be produced instantaneously in one time. The two shell covers for containers nearly has the same quality, the same appearance, the same specification, and the same size. The utility model is suitable for being used for processing and manufacturing the shell covers of petrochemical industry containers, and the shell covers can be used times without number. The finished goods can be gotten by the shell cover blank instantaneously. So the utility model has the advantages of low cost, simple operation, and high safety while in use. The utility model can be mastered by ordinary engineers.

Description

Double directional explosive forming container closing device

The utility model belongs to stress metal forming technique field, specifically a kind of amphiorentation explosive forming vessel head device that is used for the process vessel end socket.

Single now directed no die cavity blast pressure forming technique has become ripe.But the end socket of its shaping is often variant on geometry, simultaneously, bigger on dosage, this is because point charge is to discharge around it with spherical at the explosion time energy, it is useful having only the part to end socket, and discharges other direction, then makes invalid energy and consumes.The phase intercommunication, production efficiency is low, and cost is also just higher.

The purpose of the utility model is to overcome the deficiency of above technology, and the high production rate that provides a kind of once blast can produce two end sockets, the novel amphiorentation explosive forming vessel head device of low energy consumption.

The purpose of this utility model is achieved in that a kind of amphiorentation explosive forming vessel head device, comprise the blasting charge, medium, enclosure, support, mold, bed die, go up blank, blank down, it is characterized in that it once explodes to make a mold and a bed die of blank and the while moulding of following blank.The medium center that explosive places enclosure to surround, can it be detonated with electric cap or fuse cord, liquid or solid granule materials such as medium with water, soil, sand, the mold bed die is located with several supports, to keep the position of blank and following blank, behind detonation of a cartridge, its energy is rapidly to diffusion all around, the energy of its middle and lower part is passed to down blank, force down blank to flow into the bed die chamber and be shaped, the energy on top passes to blank, forces blank to flow into the mold chamber and is shaped, so just obtain the end socket product of two shapings.

Advantage of the present utility model is, it just can obtain two end sockets through once exploding, and its geometry size is basic identical, and a pressure vessel often needs two end sockets, to producing pressure vessel factory, the outward appearance of the pressure vessel of being produced and physical dimension will fully be guaranteed like this.With respect to single directional explosion moulding, productivity ratio has improved, and energy consumption has reduced, and production cost has also decreased.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing is the utility model schematic diagram.

As shown in drawings, the utility model by the blasting charge (1), medium (2), enclosure (3), support (4), up and down blank (5), mould (6), bolt (7) are formed up and down.The blasting charge (1) is the prismatic point charge, place the centre of prismatic cartridge bag (1) by detonator or fuse cord, the making of cartridge bag, be when transmitting medium with water, available common tarred brown paper packing, if when doing to transmit medium with sand or soil property class, the material of cartridge bag, packings such as available tarred brown paper, yellow plate paper.Medium (2) is sand or water, make the energy transmission medium of explosion time.Enclosure (3) is a Cylinder, and making material can be with tarred brown paper or yellow plate paper, and it is usefulness when transmitting medium that tarred brown paper is only limited to water, serves as that the two is all available when transmitting medium with sand, soil.Supporting (4) is the positioner of mould up and down, and connects the usefulness of support, and its quantity can be decided with the size of making end socket or other geometry thing, but generally must not be less than 3.Blank (5) is the sheet metal blank that needs shaping up and down, the utility model device, and available sheet material is: the general steel plate of ferrous metal, corrosion resistant plate and non-ferrous metal plate etc.Mould (6) is no die cavity flange form explosive forming film tool up and down, it is few more than the manufacturing of film tool is looked when producing, if the manufacturing of the workpiece of a spot of end socket and other geometry, available steel plate welding, and reinforcement should be arranged, make weld mold that higher intensity and rigidity be arranged, if the workpiece of the end socket of producing and other geometry is a lot, and consider durable in usely again, then available spheroidal graphite cast-iron or cast steel burn annotates whole no die cavity mold.Bolt (7) is that mold supports up and down.(4) for connecting mould thimble up and down.

The utility model be applicable to the petrochemical industry tankage end socket processing and manufacturing and can use repeatedly.The end socket blank can obtain finished product in instant of detonation, Gu with low cost, in use simple to operate, safe and reliable, so can be grasped by the general engineering technology personnel.

Claims

1, a kind of amphiorentation explosive forming vessel head device, comprise the blasting charge, medium, enclosure, support, mold, bed die, go up blank, following blank, it is characterized in that a mold and a bed die that it once explodes blank and following blank are shaped simultaneously.

2, device according to claim 1 is characterized in that the medium center that the said blasting charge places enclosure to surround.

3, device according to claim 1 is characterized in that said media fluid, and for example water also can be used the solid particle object, for example soil or sand.
