Below in conjunction with accompanying drawing most preferred embodiment of the present invention is further described.
Such as Fig. 1, shown in 2, a kind of detonation tool is annotated the powder charge rising head, this rising head comprises rising head body 1, the first core bar 2, push rod 3, the second core bar 4 and blaster case 5, the first core bar 2 and the second core bar 4 be vertical being placed in the blaster case 5 side by side, the first core bar 2 and the second core bar 4 width between centerss are 16-18mm, the first core bar 2 and the second core bar 4 relative blaster case 5 center arrangement, the first core bar 2 and the second core bar 4 top end diameter are Φ 6-Φ 10mm, the total length tapering is 1: 10, blaster case 5 upper ends are opening, and the first core bar 2 and the second core bar 4 protrude from blaster case 5 upper end 5-8mm; Rising head body 1 bottom diameter is than the large 0.5-lmm of blaster case 5 external diameters, rising head body 1 bottom arranges respectively the first core bar pilot hole 6, the second core bar pilot hole 7, pouring hole 8 and venting hole 9, the first core bar pilot hole 6 and the first core bar 2 couplings, the second core bar pilot hole 7 and the second core bar 4 couplings, pouring hole 8 is positioned on the first core bar pilot hole 6 and the second core bar pilot hole 7 cross central lines, distance center 20mm, pouring hole 8 upper end diameter are Φ 15mm, pouring hole 8 lower end diameter are Φ 11mm, be uniform-distribution with 6-10 venting hole 9 on the center circle on rising head body 1 bottom surface, venting hole 9 upper end diameter are Φ 5mm, venting hole 9 lower end diameter are Φ 3mm, rising head body 1 is placed on the blaster case 5, and assemble with the first core bar 2 and the second core bar 4, the first core bar 2 inserts in the first core bar pilot hole 6, the first core bar 2 and the first core bar pilot hole 6 adopt running fit, gap length is 0.1-0.25mm, the second core bar 4 inserts in the second core bar pilot hole 7, the second core bar 4 and the second core bar pilot hole 7 adopt running fit, and gap length is 0.1-0.25mm.Rising head body 1 upper end diameter is 80mm, and the Tapered teeth of rising head body 1 upper end and rising head body 1 bottom is 10-15 °, is provided with push rod 3 at rising head body 1 apart from 20mm position, bottom.Push rod 3 mainly is to make rising head separate usefulness with powder column during for automatic production in the purpose of this setting.When automatic production, powder column enters in the groove of push-pull device push rod 3 by back mode device jack-up, and the push-pull device horizontal balance drives push rod 3 and makes rising head body 1 along blaster case 5 central rotation 3-5 °, and rising head body 1 is separated with blaster case 5.
The first core bar 2, the second core bar 4 and rising head body 1 internal surface have adopted the teflon thermal spraying treatment, and coat-thickness is 15-20 μ m; The sectional area sum of venting hole 9 is greater than the 50%-60% of pouring hole 8 sectional areas.
Its detailed process is described as follows:
The first core bar 2 and the second core bar 4 are assembled on the pallet take wood pallets as transport agent, after manually blaster case 5 being placed on the collet of the first core bar 2 and the second core bar 4, again with rising head body 1 along the first core bar hole 6 and the second core bar hole 7 insert the first core bars 2 and the second core bar 4 and with blaster case 5 matched togethers.
Rising head body 1 cavity volume is the 15-20% of the blaster case 5 product useful volumes that will pour into a mould, rising head body 1 inner chamber is conical, cone angle is 10-15 °, rising head body 1 lower end and blaster case 5 are mating surface, the degree of depth 15mm of blaster case 5 is inserted in rising head body 1 lower end, purpose is to prevent that rising head body 1 from coming off from blaster case 5 in the wood pallets moving process, and rising head body 1 can prevent also that with blaster case 5 end face close contacts liquid from flowing out from rising head body 1 lower surface along blaster case 5 sidewalls simultaneously.Rising head body 1 bottom surface and blaster case 5 contact jaw face thicknesses are 2-3mm, be provided with the first core bar pilot hole 6, the second core bar pilot hole 7, pouring hole 8 and venting hole 9 in this bottom surface, wherein the first core bar pilot hole 6 and the second core bar pilot hole 7 respectively with the first core bar 2 and the second core bar 4 running fit.Tolerance clearance is put into the first core bar 2 and the second core bar 4 is advisable so that rising head body 1 is easy and convenient, is generally 0.1-0.25mm.Pouring hole 8 and venting hole 9 are taper hole, cone angle is 90 °, and venting hole 9 arranges 6-10 venting hole 9 according to blaster case 5, is 7 in Fig. 2, venting hole 9 lower surface diameters are Φ 3mm, and it is on the center circumferential of Φ 40mm that venting hole 9 is evenly arranged in rising head body 1 bottom surface diameter.Pouring hole 8 lower end diameter are 12mm, the large 2-5mm of liquid outlet diameter than casting valve, be the sprue channel open of liquid, liquid injects blaster cases 5 bottoms by casting valve by pouring hole 8 during cast, again by blaster case 5 bottom climbeds until reach required liquid position in the rising head body 1.The sectional area sum of all venting holes 9 is greater than the 50%-60% of the sectional area of pouring hole 8.The gas of being more convenient for like this in the blaster case 5 is discharged, and avoids forming in the product pore.Push rod 3 diameters are 10-15mm, and leaning out rising head body 1 outer electrical path length is 20-30mm, and push rod 3 and blaster case 5 couplings are installed on the rising head body 1.Arranging of push rod 3 mainly is to use in order to move back rising head in the automatic production.
Each assembly material of rising head is carbon steel, also can adopt other metallic substance, and surface smoothness is more than 8 class precisions.The whole Teflon hot-spraying techniques that adopts of rising head body 1 internal surface, the first core bar 2 and the second core bar 4 outside surfaces, coat-thickness is 15-20 μ m.Adopting the hot-spraying techniques purpose is to guarantee not adhere to behind the liquid crystallization and freezing, be convenient to separating of the rising head medicine that in rising head body 1, produces in the casting process and rising head body 1, the powder column that is cast in the blaster case 5 is withdrawed from from the first core bar 2 and the second core bar 4 smoothly.
Rising head of the present invention be for detonation tool traditional artificial notes powder charge produce some problems that exist and invent a kind of simple in structure, safe and reliable, can realize the device that the automatization serialization is produced, broken through the technical bottleneck of traditional artificial second pouring.Especially realize the disposable automatic casting of detonation tool by this invention, avoided product easily to form shrinkage cavity, pore, coarse crystallization, defects i.e.cracks, guaranteed the quality of product, realized detonation tool production serialization automatization.By adopting the riser gating mode to produce detonation tool, improved and annotated the work situation that powder charge is produced, ensured quality product.Reduce the site operation personnel, improved the safety of producing equipment, formed the novel process that the detonation tool cast is produced.
