Abstract
The utility model relates to a machine tool for a crane whole span beam hydraulic detonation forming which is characterized in that a prestressed rigid container composed of a well cylinder 1, an inertia assembly set 2, etc., the working medium-water 5 is put into the container, an explosive material detonator 6 and a piece 8 being processed are arranged on the cavity die 9 of a foundation 11, a whole span beam 15 of a crane, the prestressed rigid container can expand freely, and the camber of (f) =1.4L< k >/1000 can be formed one time by the detonation forming when the detonation occurs. The utility model has the advantages of simple structure and high production efficiency.
Description
The utility model relates to the explosive forming device.
The explosive forming technology has been used to process pressure vessels for the chemical industry, aerospace parts, petroleum industry and boiler industry in recent years.The clear 49-11305 of Japan Patent " punch forming device " is used for the processing metal small container effectively, makes each thickness partly of explosive forming part even.But the explosive forming device of prior art all is limited to smaller part.Crane girder adopts polylith plane steel plate butt joint welding method to constitute case structure always.There are many shortcomings in the girder of this structure, and the inventor reforms this, is designed to a kind of crane whole span beam, and has declared patent.How the full span girder of this crane of machine-shaping is camber (f)=1.4L
K/ 1000 the such huge monster of ∩ template, its shaped device has just become a difficult problem.
The purpose of this utility model is to solve an above-mentioned difficult problem, designs a kind of explosive forming device that can process the crane whole span beam.
Structure of the present utility model is formed by three major parts, and first is the pit shaft parts partly, and these parts are by pit shaft, and the bolster in coasting body assembly and the spacing buffering cannelure constitutes.The purpose of these parts is: the one, constitute a bulk container, and wherein can hold a large amount of working medias--water.The 2nd, it is a kind of prestressing force rigid body that can free wxpansion, can effectively absorb the shock wave of blast.Second partly is workpiece: it comprises workpiece to be machined, cavity punch set component, working medium water and explosives and detonators, band etc.The effect of these parts is ignition charges, and the shock wave that blast forms passes through working media--water is delivered on the workpiece to be machined, and this metallic plate is stamped on the punch, is processed into ∩ shape girder.The 3rd is basic components partly.This basis is provided with vacuum tube, can link to each other with the evacuator of outside, below the metallic plate with the punch both sides in air in the cavity that forms extract out, work piece both sides under the explosion wave effect can be close on the punch.The main effect on basis is first and second parts of supporting and discharges working medium water after machine-shaping.
The drawing explanation:
Fig. 1: crane whole span beam water-exploding forming lathe cross-sectional view;
Fig. 2: A is to view;
Fig. 3: B is to view;
Fig. 4: crane whole span beam water-exploding forming lathe sectional oblique drawing;
Fig. 5: the sectional oblique drawing of crane whole span beam.
Now further specify the utility model with embodiment in conjunction with the accompanying drawings.Among the figure:
1-pit shaft 2-coasting body assembly
3-lumps of wood 4-rubber slab
5-working medium water 6-explosives and detonators
7-band 8-work piece
The buried bolt of 9-cavity punch set component 10-
11-basis 12-drainage pipeline
13-elasticity blank cap 14-vacuum tube
15-crane whole span beam 16-exhaust cavity
The spacing buffering cannelure of 17-
Structure of the present utility model is: the outside that metallic plate is placed in spacing buffering cannelure 17 forms flute profile pit shaft 1, and coasting body sub-assembly 2 is placed in the inwall of pit shaft 1 successively, and with pit shaft 1 inwall near, pit shaft 1 peripheral banding is in aggregates.Respectively establish the bolster lumps of wood 3 in the both sides of spacing buffering cannelure 17 and lay rubber slab 4 on the bottom and the top of cannelure 17.By constituted a tun with upper part.In container, fill working media--water 5, in water, establish some explosives and detonators 6, workpiece to be machined 8 is placed in the top of cavity punch set component 9, the buried bolt 10 of punch set component 9 usefulness is fixed on the basis 11, for preventing that working medium water from 8 times leakages of work piece, is provided with band 7 between workpiece 8 and rubber slab 4.For the air in the cavity 16 of extracting the formation of work piece 8 and punch 9 both sides out, establish vacuum-pumping tube 14, link to each other with the external vacuum machine.For remaining water after the discharge explosive forming, by being located at the drainage pipeline 12 in the basis 11, the elasticity blank cap 13 of opening its end is discharged water 5.In order to make crane whole span beam L
KHas camber (f)=1.4L
K/ 1000, punch 9 longitudinally is processed into is camber (f)=1.4L
K/ 1000 radian.
Explosive forming process: work piece 8, maximum span can reach 43.5 meters, be placed on the cavity punch 9, central lines, work piece 8 peripheries seal with band 7 with place, basic 11 upper surface outers everywhere, vacuum tube 14 connects evacuator and extracts air in the cavity 16 out, places explosives and detonators 6 and connects main firing.Explosion wave impacts on the work piece 8 by WATER AS FLOW MEDIUM 5, and work piece 8 is processed to ∩ type crane girder 15 by flat board.Open elasticity blank cap 13, WATER AS FLOW MEDIUM is discharged through passing away 12.
Remarkable result of the present utility model is that this explosive forming lathe can become to have camber f=1.4L by an explosive processingK/ 1000 crane whole span beam. This machine tool structure is simple, and production efficiency height, its power are equivalent to 2000 tons of hydraulic presses.
Claims (2)
1, a kind of crane whole span beam water-exploding forming lathe, of the present utility model being characterised in that: inertia sub-assembly 2 is placed in the inwall of pit shaft 1 successively, in spacing buffering cannelure 17, establish the bolster lumps of wood 3 and rubber slab 4, explosives and detonators 6 is set in working medium water 5, work piece 8 is placed in the top of punch set component 9, buried bolt 10 fastening punch set components 9 are on basis 11, between workpiece 8 and rubber slab 4, band 7 is set, vacuum tube 14 links to each other with cavity 16, establish drainage pipeline 12 in basis 11, elasticity blank cap 13 is established in its end.
